Long-term changes in frailty and incident atrial fibrillation: multicenter prospective cohort study

Abstract Background Atrial fibrillation is the most common sustained cardiac arrhythmia and is prevalent among the elderly. Previous findings indicated a higher prevalence of AF in frail adults and frailty prevalent in AF patients. However, the association between dynamic changes of frailty and risk of new-onset AF is unclear. Purpose We aimed to investigate the associations of long-term changes in frailty with incident AF. Its associations with heart failure (HF), coronary heart disease (CHD), and stroke were also evaluated as a secondary aim. Methods Over 50,000 participants from UK Biobank cohort were included, with available frailty index (FI) data and free of AF, HF, CHD or stroke in both baseline and final follow-up assessments. Participants were categorized into nonfrailty, prefrailty and frailty based on their FI scores. Changes of frailty status from baseline to final follow-up assessment included alleviation, maintenance, and aggravation. Thus, transitions of frailty status included 7 categories: nonfrailty maintenance, nonfrailty aggravation (nonfrailty to prefrailty or frailty), prefrailty alleviation (prefrailty to nonfrailty), prefrailty maintenance, prefrailty aggravation (prefrailty to frailty), frailty alleviation (frailty to prefrailty or nonfrailty), and frailty maintenance. FI in baseline and follow-ups are used to calculate the trajectories of frailty (ΔFI). Cox proportional hazard models were used. Results Compared with nonfrailty at baseline, the HRs (95% CI) of AF for prefrailty and frailty were 1.32 (1.29, 1.36) and 1.89 (1.83, 1.96) in the multivariable-adjusted model. During a median of 5.1 years of follow-up from the final assessment, 1729 cases of AF were recorded. Frailty trajectory analysis showed that even a 0.01 point/year increase in ΔFI was associated with 14% (95% CI 1.08-1.20) higher risk of AF, independent of baseline FI and the risk rose to 1.89 (1.45, 2.46) with per 0.05 point/year increase in ΔFI. This association was strengthened in low genetic risk of AF, but sex, age, smoking status, alcohol intake, obesity, hypertension, diabetes and cancer did not materially modify the associations. Moreover, compared with nonfrailty maintenance, sustained frailty had the highest risk of AF (HR 1.95, 1.61-2.36). Alleviation from frailty reduced the risk of AF by 30% (95%CI 0.53-0.94), compared to sustained frailty. These associations were similar in HF and CHD, however, not significant in stroke. Conclusions Middle aged and elderly people, including those with diabetes, obesity and hypertension, may gain substantial benefits in risk of AF, HF and CHD by becoming less frail or maintaining nonfrailty, irrespective of past frailty status and established risk factors, delivering public health implications for the necessity of early identification and timely interventions of frailty in heart health management.

Associations of Neighborhood Food Retail Environments with Weight Status in a Regional Pediatric Health System.

Background: There have been mixed findings on the relationships between childhood obesity and macroscale retail food environments. The current study investigates associations of the neighborhood retail food environment with changes in children's weight status over 6 years in the Kansas City Metropolitan area. Methods: Anthropometrics and home addresses were collected during routine well-child visits in a large pediatric hospital (n = 4493; >75% were Black or Latinx children). Children had measures collected during two time periods ([Time 1] 2012-2014, [Time 2] 2017-2019). Establishment-level food environment data were used to determine the number of four types of food outlets within a 0.5-mile buffer from the children's residence: supermarkets/large grocery stores, convenience stores/small grocery stores, limited-service restaurants, and full-service restaurants. Children who moved residences between periods were "movers" (n = 1052). Associations of baseline and changes in food environment status with Time 2 weight status were assessed using mixed-effects models. Results: Movers who experienced no change in the number of convenience stores or small grocery stores within a 0.5-mile of their home had increased likelihoods of having overweight/obesity and less favorable BMIz changes, compared with movers who experienced a decrease in convenience stores/small grocery stores within a 0.5-mile distance. No associations were observed among nonmovers. Conclusion: Findings suggest that moving to an area with fewer unhealthy retail food outlets (e.g., convenience stores) is associated with a lower risk of obesity in children. Future research is needed to determine whether larger-scale changes to the retail food environment within a neighborhood can support children's healthy weight.

Association between provegetarian food patterns and micronutrient adequacy in preschoolers: the SENDO project

This study aims to examine the association between different versions of a provegetarian food pattern and micronutrient adequacy in a population of children from the SENDO Project. Children aged 4–5 years old were recruited and baseline information on diet, lifestyle and socio-demographic characteristics was collected through self-administered online questionnaires completed by their parents. Scores were calculated for overall, healthful, and unhealthful provegetarian food patterns (FP) using an a priori approach. Participants were categorized into tertiles according to their scores. Micronutrient adequacy was assessed using the Estimated Average Requirement (EAR) cut-off point. Multivariate analyses were performed to evaluate the relationship between tertiles of each provegetarian FP and the risk of inadequate micronutrient intake (failing to meet ≥ 3 requirements). Despite lower intakes of certain micronutrients, children with higher scores in the healthful provegetarian FP did not exhibit a higher prevalence of inadequacy. Children in the highest tertile of this index had 0.47-fold lower odds (95%CI 0.23–0.95) of having ≥ 3 inadequate micronutrient intakes than their peers in the lowest tertile, after adjusting for potential confounders. In contrast, children in the highest tertile of the unhealthful provegetarian FP had 20.06-fold higher odds (95%CI 9.19–43.79) of having ≥ 3 inadequate micronutrient intakes compared to children in the lowest tertile. Conclusions: Adherence to a healthful provegetarian food pattern is associated with improved nutritional adequacy in preschoolers, while following an unhealthful pattern is detrimental to micronutrient adequacy. These results suggest that moderate reductions in animal food consumption within a healthy diet may not compromise micronutrient adequacy in young children. Further research is needed to explore the impact of diets reduced in animal food intake on the health of children.What is Known:• There's a notable trend towards plant-based diets due to health and sustainability concerns.• Research links plant-based diets in adults with lower risks of obesity, cardiovascular disease, and cancer.What is New:• A new study examines how different versions of a provegetarian food pattern affect micronutrient adequacy in children, using a moderate and stepwise approach.• Following a healthful provegetarian food pattern enhances nutritional adequacy in preschoolers, whereas an unhealthful pattern negatively impacts micronutrient adequacy.

The Health and Nutritional Benefits of Fruits and Vegetables to Reduce the Risk of Obesity and High Blood Lipids

Background: Vegetables and fruits are an important part of a healthy diet and help with growth and support body functions and physical, mental, and social well-being at all ages. They can also help prevent all forms of malnutrition, such as undernutrition, micronutrient deficiencies, obesity, and overweight, and reduce the risk of non-communicable diseases. World Health Organization consumption of at least 400 grams of fruits and vegetables per day, or five servings of 80 grams each, and the reasons for the sad fact that most people do not eat enough of them to maintain a healthy life for the sake of obesity treatment and weight reduction. Objectives: The aim of the study was to investigate the effects of increasing fruit and vegetable intake rich in antioxidants and vitamins on people at risk of obesity and high levels of blood fat and to provide education about its benefits and the amount of daily rations. Methods: This a descriptive cross-sectional study, 160 obese women underwent to Aspetar ospital in Misurata city during The period (October–December 2022) and they were divided into two groups of 80 women per group. The first group was presented with a weight-loss diet devoid of vegetables and fruits. The second group was given a weight-loss diet rich in vegetables, including cucumber, lettuce, tomato, and fruits (kiwi, apple, and orange). For three consecutive months. Results: The findings were a decrease in weight with an average of 8 kg per woman for the first group and 15 kg per woman for the second group, and the average cholesterol and triglycerides were 280 mg/100 dL of blood and 230 mg/100 dL of blood, respectively, for the women of the first group. While it was 150 mg/100 dL blood and 90 mg/100 dL blood for the women of the second group, with some daily light exercise for all women in the two groups. Conclusion: This study indicates that consumption of three to five portions/day of fruit and vegetables is highly associated with prevention and a low risk of obesity, high blood fat, cholesterol, and cardiovascular disease. Therefore, we recommend relying on eating vegetables and fruits daily to reduce weight and blood fats, improve health, and nourish the body.

Trends and social determinants of the obesity epidemic among reproductive-age women in ten Asian countries

The rapid epidemiological transition in Asian countries, resulting from the rising trend of urbanisation and lifestyle changes, is associated with an increasing risk of obesity in women of reproductive age. This is the first study to investigate the trends and population-attributable fraction (PAF) of obesity, and the interaction effects of education and wealth on obesity among reproductive-age women aged 15–49 years in ten Asian countries. This cross-sectional study examined the most recent (2000 to 2022) Demographic and Health Surveys (DHS) data from ten Central and Southeast Asian countries. Multilevel multinomial logistic regression models were used to compute odds ratios (ORs). PAFs adjusted for communality were calculated using adjusted ORs and prevalence estimates for each risk factor. This study included a weighted sample of 743,494 reproductive-age women. All the countries showed an increasing trend for obesity and a decreasing trend for underweight, except for the Maldives. The highest PAFs of obesity were associated with women who were married (PAF = 22.2%; 95% CI 22.1, 22.4), aged 35–49 years (PAF = 16.4%; 95% CI 15.5, 17.1), resided in wealthy households (PAF = 14.5%; 95% CI 14.4, 14.5), watched television regularly (PAF = 12.5%; 95% CI 12.1, 12.8), and lived in urban areas (PAF = 7.8%; 95% CI 7.7, 8.0). The combined PAF showed that these five risk factors were associated with 73.3% (95% CI 71.8, 74.9) of obesity among reproductive-age women. Interaction analysis between women’s education and household wealth revealed that having a secondary or higher level of education and residing in a wealthier household was associated with a lower risk of obesity (OR = 0.71, 95% CI 0.66, 0.76). The findings of this study suggest that, in order to address the rising rate of obesity among women in Asian countries, education and lifestyle modifications in urban areas should be a priority. Pakistan and the Maldives need to be a priority given the rapidly increasing trends in obesity and underweight subpopulations in their respective countries.

Association of Weight Status and Waist Circumference with Physical Activity in people with Schizophrenia Spectrum Disorders and healthy controls

BackgroundIndividuals with Schizophrenia Spectrum Disorders (SSD) often suffer from obesity and do limited Physical Activity (PA). PA has many beneficial effects on a variety of somatic and mental variables and it should be strengthened among people with mental disorders. The relationship between Body Mass Index (BMI), Waist Circumference (WC), and PA in this population is poorly understood, with a lack of precise PA assessment. This study investigates the association between BMI, WC, weight, and PA in individuals with SSD and controls using accelerometers. MethodsOne hundred twenty-six patients with SSD (residents and outpatients) and 110 sex- and age-matched controls were enrolled. Clinical, sociodemographic, and quality-of-life data were collected. PA was measured with a tri-axial ActiGraph GT9X and quantified by Vector Magnitude (VM). Relationships between PA and BMI, WC, and weight changes were analysed using linear regression models. ResultsPatients were more likely to be unmarried, unemployed, and less educated compared to controls (p < 0.001). Residents had more medical comorbidities (p = 0.001), while outpatients had higher BMI, weight, and WC (p < 0.001). Residents reported more severe psychopathology, lower functioning, and greater use of psychopharmacological medications (p < 0.001). Higher PA levels were not significantly associated with lower BMI, WC, or weight. Although not statistically significant, increased PA showed a trend towards lower obesity risk. ConclusionsSociodemographic, medical, and clinical characteristics of individuals with SSD define vulnerability factors that can inform tailored interventions to improve PA.

Relationship of vegetarianism with body weight loss and ASCVD.

The association between a plant-based diet and weight loss and atherosclerotic cardiovascular disease (ASCVD) has not been fully elucidated. We performed a pooled analysis and Mendelian randomization (MR) analysis to investigate this question. We searched for randomized controlled trials on the effects of a plant-based diet on weight loss compared with a non-plant-based diet. In addition, a two-sample MR study was conducted. IVs were obtained from the genome-wide association studies (GWAS) on the exposures, and we obtained summary statistics on the outcomes. The inverse-variance weighted (IVW) method was used as the main analysis and other MR methods were performed as supplementary analyses. Individuals on the plant-based diet lost more weight than the non-plant-based diet group (WMD -0.96 kg; 95% CI: -1.32 to -0.60). Population conditions and energy restriction were identified as the study-level factors that influenced the pooling results in the subgroup analyses. Increased consumption of raw vegetables was significantly associated with lower BMI (IVW, β -0.35, 95% CI: -0.62 to -0.08, p = 0.012) and lower risk of obesity (IVW, OR 0.11, 95% CI: 0.01 to 0.99, p = 0.048), coronary heart disease (IVW, OR 0.44, 95% CI: 0.21 to 0.92, p = 0.029) and myocardial infarction (IVW, OR 0.39,95% CI: 0.15 to 0.98, p = 0.045) and a higher HDL-C (IVW, β 0.47, 95% CI: 0.24 to 0.70, p = 4×10-5). The present findings suggest that raw vegetable intake is beneficial for weight loss and prevention of ASCVD.

Beneficial effects of short-term breastfeeding versus non-breastfeeding in early life against childhood obesity: findings from the US-based population study NHANES

BackgroundBreastfeeding is widely recognized for its potential to reduce childhood obesity. However, research investigating these benefits in children breastfed for a short duration (up to 6 months) remains limited despite this being a common practice globally.MethodsThis study focused on a population breastfed for 6 months or less to determine the potential benefits of short-term breastfeeding for preventing childhood obesity. Data were collected from five survey cycles of an US-based population study (the National Health and Nutrition Examination Survey (NHANES)), spanning 2009–2020. A sample of 3,211 children aged 2–6 years was selected, including 1,373 never breastfed and 1,838 ever breastfed. Logistic regression analysis examined the direct association between short-term breastfeeding and childhood obesity. Subsequent subgroup analyses were conducted. Additionally, stratified logistic regression explored the relationship between childhood obesity and the introduction of other early nutrition in both ever-breastfed and never-breastfed children.ResultsOverall, breastfeeding for 6 months or less did not directly prevent childhood obesity. However, among participants with older mothers (aged 35 or above), short-term breastfeeding was associated with a lower risk of childhood obesity compared to never being breastfed (OR 0.31, 95% CI: 0.17, 0.59). Similarly, children aged 3–4 years who were breastfed for > 3 ~ 6 months exhibited a lower obesity risk (OR 0.56, 95% CI: 0.35, 0.89). In ever-breastfed children, delayed infant formula introduction was linked to a lower risk of obesity (P-trend < 0.05: introduction at age ≤ 1 vs. >1 ~ 3 vs. >3 months). Conversely, for non-breastfed children, introducing milk (other than breast milk or formula) later (≥ 12 versus < 12 months) and introducing alternatives to whole cow’s milk were associated with lower obesity risks (OR 0.54, 95% CI: 0.37, 0.78; OR 0.21, 95% CI: 0.08, 0.60, respectively). Notably, these trends were not observed in ever-breastfed children.ConclusionsShort-term breastfeeding may offer some benefits in preventing childhood obesity for specific populations. Additionally, it could potentially mitigate risks associated with the introduction of formula and cow’s milk at inappropriate times.

Seafood intake in childhood/adolescence and the risk of obesity: results from a Nationwide Cohort Study

Background & aimsObesity has been linked to various detrimental health consequences. While there is established evidence of a negative correlation between seafood consumption and obesity in adults, the current research on the association between seafood intake in childhood/adolescence and the risk of obesity is lacking. Our aim was to evaluate the association between seafood intake in childhood/adolescence and the risk of obesity in a Chinese nationwide cohort.MethodsWe utilized data from the China Health and Nutrition Survey (CHNS) from the year of 1997 to 2015. Seafood consumption was evaluated through 3-day 24-hour recalls. In our study, overweight/obesity status was determined based on the Chinese Criteria of Overweight and Obesity in School-age Children and Adolescents (WS/T 586–2018), while abdominal obesity status was determined according to the Chinese Criteria of Waist Circumference Screening Threshold among Children and Adolescents (WS/T 611–2018).ResultsDuring an average follow-up of 7.9 years, 404 cases developed overweight/obesity among 2206 participants in the seafood-overweight/obesity analysis, while 381 cases developed abdominal obesity among 2256 participants in the seafood-abdominal-obesity analysis. The high-consumer group was associated with 35% lower risk of overweight/obesity risk and 26% lower risk of abdominal obesity after fully adjusting for sociodemographic and lifestyle factors, compared with the non-consumer group. Considering different cooking methods, boiled seafood consumption was associated with 43% lower risk of overweight/obesity and 23% lower risk of abdominal obesity in the fully adjusted model, while stir-fried seafood did not demonstrate a statistical significance.ConclusionHigher intake of seafood in childhood/adolescents, particularly in a boiled way, was associated with lower obesity risk.

The EAT-Lancet Diet Index Is Associated with Lower Obesity and Incidence of Type 2 Diabetes in the Multiethnic Cohort

BackgroundThe EAT-Lancet Commission has developed dietary recommendations, named the EAT-Lancet diet, to promote healthy nutrition and sustainable food production worldwide. ObjectivesWe developed an adapted score for the EAT-Lancet diet for participants of the Multiethnic Cohort (MEC) Study and its relation with incidence of obesity and type 2 diabetes (T2D). MethodsThe MEC includes 5 ethnic groups followed since 1993–1996. Anthropometric characteristics and dietary intake were assessed by questionnaire at cohort entry (Qx1) and 10 y later (Qx3). To create the EAT-Lancet index (range: 0–48 points), a 3-point scoring system for 16 food groups standardized to 2500 kcal/d was applied. T2D cases were identified through repeated self-reports and administrative data. In a prospective design, obesity at Qx3 and T2D incidence were evaluated using Cox regression to estimate hazard ratios (HR) with 95% confidence intervals (95% CI) while adjusting for relevant covariates. ResultsAmong 193,379 MEC participants, the overall mean of the EAT-Lancet index score was 25 ± 4 points and 46,140 new T2D cases were identified. Higher adjusted means were observed in females than males, in participants of Japanese American and Native Hawaiian ancestry, and in those with healthy weight than overweight or obese. Obesity was lower in cohort members with higher EAT-Lancet scores (HR: 0.76; 95% CI: 0.73, 0.79 for tertile 3 compared with 1). Although T2D incidence was 10% lower among participants in the highest (27–42 points) compared with the lowest (9–23 points) EAT-Lancet index tertile (HR: 0.90; 95% CI: 0.88, 0.92), the association was attenuated after BMI adjustment (HR: 0.97; 95% CI: 0.94, 0.99). This inverse association with T2D was restricted to African American and European American participants. ConclusionsThese findings support the hypothesis that adherence to the EAT-Lancet diet is related to a lower risk of obesity, which may be partially responsible for the small reduction in T2D incidence.

Breastfeeding duration and brain-body development in 9-10-year-olds: modulating effect of socioeconomic levels.

To investigate relationships of breastfeeding duration with brain structure and adiposity markers in youth and how these relationships are modified by neighborhood socioeconomic environments (SEEs). This was a cross-sectional study of youth enrolled in the Adolescent Brain and Cognitive Development (ABCD) Study® (n = 7511). Mixed effects models examined associations of breastfeeding duration with global brain measures and adiposity markers, adjusting for sociodemographic, pre- and post-natal covariates. Stratified analysis was performed by area deprivation index (ADI) tertiles. Total cortical surface area (SA) (False Discovery Rate - FDR corrected P < 0.001), cortical (FDR corrected P < 0.001) and subcortical gray matter (GM) volume (FDR corrected P < 0.001) increased with increased breastfeeding duration. Body mass index (BMI) z-scores (FDR corrected P = 0.001), waist circumference (FDR corrected P = 0.002) and waist-to-height ratio (WHtR) (FDR corrected P = 0.001) decreased with increased breastfeeding duration. Breastfeeding duration was inversely associated with adiposity in youth from high- and medium- ADI neighborhoods, but positively associated with SA across ADI tertiles. In this cross-sectional study, longer breastfeeding duration was associated with lower adiposity indices, particularly in youth from lower SEEs and greater SA across SEE levels. Longer breastfeeding duration showed long-term associations with brain and body development for offspring. Building on previous findings that longer breastfeeding duration is associated with healthier weight gain, lower obesity risk, and brain white matter development in infancy, our results find longer breastfeeding duration to be associated with lower adiposity indices and greater cortical and subcortical gray matter volume, and cortical surface area during peri-adolescence. Children from lower socioeconomic environments (SEEs) demonstrated stronger negative associations of breastfeeding duration and adiposity indices, and children across SEEs showed positive relationships between breastfeeding duration and cortical surface area. Promoting breastfeeding, particularly among women from lower SEEs would confer long-term benefits to offspring.

PACE: a Novel Eating Behavior Phenotype to Assess Risk for Obesity in Middle Childhood

BackgroundBehavioral phenotypes that predict future weight gain are needed to identify children susceptible to obesity. ObjectivesThis prospective study developed an eating behavior risk score to predict change in adiposity over 1 y in children. MethodsData from 6 baseline visits (Time 1, T1) and a 1-y follow-up visit (Time 2, T2) were collected from 76, 7- to 8-y-old healthy children recruited from Central Pennsylvania. At T1, children had body mass index (BMI) percentiles <90 and were classified with either high (n = 33; maternal BMI ≥30 kg/m2) or low (n = 43; maternal BMI ≤25 kg/m2) familial risk for obesity. Appetitive traits and eating behaviors were assessed at T1. Adiposity was measured at T1 and T2 using dual-energy x-ray absorptiometry, with a main outcome of fat mass index (FMI; total body fat mass divided by height in meters squared). Hierarchical linear regressions determined which eating measures improved prediction of T2 FMI after adjustment for covariates in the baseline model (T1 FMI, sex, income, familial risk, and Tanner stage). ResultsFour eating measures—Portion susceptibility, Appetitive traits, loss of control eating, and eating rate—were combined into a standardized summary score called PACE. PACE improved the baseline model to predict 80% variance in T2 FMI. PACE was positively associated with the increase in FMI in children from T1 to T2, independent of familial risk (r = 0.58, P < 0.001). Although PACE was higher in girls than boys (P < 0.05), it did not differ by familial risk, income, or education. ConclusionsPACE represents a cumulative eating behavior risk score that predicts adiposity gain over 1 y in middle childhood. If PACE similarly predicts adiposity gain in a cohort with greater racial and socioeconomic diversity, it will inform the development of interventions to prevent obesity.This trial was registered at clinicaltrials.gov as NCT03341247.

Abstract PO2-02-02: BREAst Cancer Personalized NuTrition (BREACPNT): dietary intervention in HR+ breast cancer patients treated with endocrine therapy

Abstract BACKGROUND Breast cancer patients treated with adjuvant endocrine therapy commonly experience weight gain, which has been associated with low adherence to therapy and worse breast cancer prognosis. Dietary interventions are the first-line treatment for weight management in breast cancer patients and have beneficial results. Yet, the ability to maintain these outcomes requires further research. Here, we aimed to assess whether a personalized postprandial glucose targeting (PPT) diet is beneficial for weight management and metabolic health as compared with the recommended Mediterranean (MED) diet in this population. DESIGN AND METHODS BREACPNT is a phase-2 randomized trial in HR+ patients with breast cancer, treated with adjuvant endocrine therapy. We randomly assigned participants to follow a MED diet or a PPT diet for a 6-month dietary intervention and additional 6-month follow-up. The PPT diet is based on a machine-learning algorithm that integrates clinical and microbiome features to predict personal postprandial glucose responses (PPGRs). During the intervention, participants were monthly followed by a registered dietitian, they were additionally connected to a 2-week continuous glucose monitoring (CGM) on 3-timepoints, provided stool and blood samples and self-reported dietary intake using a smartphone application. RESULTS Among 127 randomized patients (mean ± SD age 53 ± 10 years, BMI 28.6 ± 5 kg/m2), 103 (81%) completed the 6-month intervention period. A total of 94 participants provided 12-month follow-up data. Both interventions led to a significant weight loss. The PPT-diet showed numerically greater weight loss with median change of -1.45kg (IQR -3.75 – 0) compared to the MED-diet with median change of -1kg (IQR -3.2 - 0.1) , however this was not significant (p=0.9). Notably, at the 12-month time point , participants in the PPT arm were more likely to maintain the weight loss (median -1.2kg, IQR -4 - 0.1) compared to participants in the MED-arm (median -0.15kg , IQR -4.25 - 1.5), p=0.14) and had significantly improved waist circumference (median, IQR; -5 cm, -8-(-2) in the PPT arm, compared to -1cm, -6.5-3 in the MED arm, p=0.01). In terms of glucose metabolism the PPT-diet led to improved glycemic control as measured by CGM, with significant lower average postprandial glucose responses (PPGRs) and glucose coefficient of variation (CV) compared to the MED-diet arm (mean 6-month change in PPGR was 2.1 ± 7.5 mg/dL × h for MED and −3.4 ± 5.6 mg/dL × h for PPT, p&amp;lt; 0.001, and the 6-month mean change for CV was 0.15 ± 2.76 for MED and −1.37 ± 3.2 for PPT, p&amp;lt; 0.01). Within the entire cohort, participants who experienced the greatest weight loss (upper quartile) were more likely to be postmenopausal compared to participants in the lower quartile. Additionally, participants who did not achieve weight loss (lower quartile) were significantly more likely to be treated with tamoxifen than AI (p=0.015). CONCLUSIONS In this dietary intervention in HR+ breast cancer patients, both PPT diet and MED diet led to weight loss and improved food quality, with a slight advantage to PPT diet. PPT diet additionally improved glycemic features as compared to MED diet, which are linked to lower risk of obesity and disease recurrence, suggesting an advantage in a glucose targeting approach. Premenopausal and Tamoxifen treated patients were less likely to lose weight through the intervention. These findings may have implications for dietary advice in clinical practice.

The Association of Free Testosterone with Sarcopenic Obesity in Community-Dwelling Older Men: A Cross-Sectional Study.

Background and Objectives: Sarcopenic obesity, a clinical condition coexisting with obesity and sarcopenia, is associated with a high risk of functional impairment, reduced quality of life, and increased mortality. A decline in age-related free testosterone (FT) levels has been reported to be associated with decreased muscle mass and muscle strength and increased fat mass. However, the association between low FT levels and risk of sarcopenic obesity has not been well studied. This study aimed to investigate the direct association between low FT levels and sarcopenic obesity. Materials and Methods: This cross-sectional study used data of 982 community-dwelling men aged 70-84 years from the Korean Frailty and Aging Cohort Study. Sarcopenia was defined according to the criteria of the Asian Group for Sarcopenia (AWGS) 2019. Obesity was defined as a body fat mass ≥28.3%. Participants who met both sarcopenia and obesity criteria were defined as having sarcopenic obesity. Low FT levels were defined as FT levels <17.35 pmol/L according to the Endocrine Society Clinical Practice Guidelines. Results: The prevalence of sarcopenia, obesity, and sarcopenic obesity was significantly higher in the low-FT group than in the normal-FT group. Low FT levels were significantly associated with a higher risk of obesity (odds ratio [OR], 2.09, 95% confidence interval [CI], 1.11-3.92), sarcopenia (2.57, 95% CI 1.08-6.10), and sarcopenic obesity (3.66, 95% CI 1.58-8.47) compared with the healthy control group. The risk of low appendicular skeletal muscle mass index (ASMI) (1.78, 95% CI 1.04-3.02) and high fat mass (1.92, 95% CI 1.12-3.31) was significantly higher in the low-FT group than in the normal-FT group. Conclusions: This study showed that low FT levels were associated with a higher risk of sarcopenic obesity. Low FT levels were mainly related to body composition parameters such as low ASMI and high fat mass.

Water intake and obesity: By amount, timing, and perceived temperature of drinking water.

Water intake has been suggested to be associated with weight control, but evidence for optimal water intake in terms of amount, timing, and temperature is sparse. Additionally, genetic predisposition to obesity, which affects satiety and energy expenditure, might interact with water intake in regulating individual adiposity risk. We conducted a cross-sectional study recruiting 172 Korean adults. Information on water intake and lifestyle factors was collected through self-reported questionnaires, and height, weight, and waist circumference (WC) were measured by researchers. The oral buccal swab was performed for genotyping of FTO rs9939609, MC4R rs17782313, BDNF rs6265 and genetic risk of obesity was calculated. Linear regression was performed to estimate mean difference in body mass index (BMI) and WC by water intake and its 95% confidence interval (95% CI). As a sensitivity analysis, logistic regression was performed to estimate odds ratio (OR) of obesity/overweight (BMI of ≥23kg/m2; WC of ≥90cm for men and of ≥80cm for women) and its 95% CI. Drinking >1L/day was significantly associated with higher BMI (mean difference: 0.90, 95% CI 0.09, 1.72) and WC (mean difference: 3.01, 95% CI 0.62, 5.41) compared with drinking ≤1L/day. Independent of total water intake, drinking before bedtime was significantly associated with lower BMI (mean difference: -0.98, 95% CI -1.91, -0.05). The results remained consistent when continuous BMI and WC were analyzed as categorical outcomes. By perceived temperature, drinking >1L/day of cold water was associated with higher BMI and WC compared with drinking ≤1L/day of water at room-temperature. By genetic predisposition to obesity, a positive association between water intake and WC was confined to participants with low genetic risk of obesity (P interaction = 0.04). In conclusion, amount, timing, and perceived temperature of water intake may be associated with adiposity risk and the associations might vary according to genetic predisposition to obesity.

Glycemic Profile and Lipid Profile in Chronic Obstructive Pulmonary Disease (COPD) Patients With and Without Metabolic Syndrome.

There is a lack of Indian data regarding the frequency of metabolic syndrome (MetS) or its components in chronic obstructive pulmonary disease (COPD). As a result, the present study aimed to determine the prevalence of MetS in COPDcases and investigate its association with COPD severity. After receiving ethical approval fromIndex Medical College and Hospital, we conducted this cross-sectional study in Indore. We recruited 100 participants with a history of COPD and divided them into two groups: those with MetS and those without. Researchers examined the subjects' fasting blood glucose, serum high-density lipoprotein, triglyceride(TG), systolic and diastolic blood pressure (SBP/DBP), waist circumference, and fasting blood glucose levels. We discovered that 59% of patients with COPD and 52% of individuals with impaired fasting glucose (IFG) had MetS (mean ± SD = 110.8 ± 32.8). In comparison, 48% (mean ± SD = 98.2 ± 24.8) of individuals with normal fasting glucose do not experience this. The incidence of MetS was higher in both groups, those with IFG and those without, but the difference was not statistically significant (t = 1.7088, df = 98; p = 0.0907). We observed X2 = 1.336, df = 1, and p = 0.2476 when we tested the association between IFGand COPD with the Chi-square test. Individuals with MetS were more likely to have high BP, raised TG levels, low HDL cholesterol, abdominal obesity, and other risk factors.

BMI Growth Profiles Among Black Children from Immigrant and US-Born Families.

A large body of research has documented racial/ethnic disparities in childhood obesity in the United States (US) but less work has sought to understand differences within racial groups. Longitudinal studies are needed to describe BMI trajectories across development, particularly for Black children from immigrant families who have been underrepresented in childhood obesity research. The current study utilizes BMI data collected longitudinally from ages 5 to 8 years and growth mixture modeling to (1) identify and visualize growth patterns among Black children from primarily Caribbean immigrant families, and (2) to compare these patterns to growth trajectories among Black children from US-born families. First, we identified four classes or trajectories of growth for Black children from immigrant families. The largest trajectory (70% of the sample) maintained non-overweight throughout the study period. A second trajectory developed overweight by age 8 (25%). Two small trajectory groups demonstrated high rates of moderate and severe obesity-i.e., specifically, a trajectory of accelerated weight gain ending in moderate/severe obesity (3%), and a trajectory of early severe obesity with BMI decreasing slightly with age (2%). We identified a very similar four class/trajectory model among Black children from US-born families, and compared the model to the one for children from immigrant families using multi-group growth mixture modeling. We found that the patterns of growth did not differ significantly between the populations, with two notable exceptions. Among Black children from immigrant families, ∼ 5% were classified into the two heavier BMI trajectories, compared to ∼ 11% of children from US-born families. Additionally, among children with an accelerated weight gain trajectory, children from immigrant families had lower BMIs on average at each time point than children from US-born families. These findings describe the multiple trajectories of weight gain among Black children from immigrant families and demonstrate that although these trajectories are largely similar to those of Black children from US-born families, the differences provide some evidence for lower obesity risk among Black children from immigrant families compared to Black children from US-born families. As this study is the first to describe BMI trajectories for Black children from immigrant families across early and middle childhood, future work is needed to replicate these results and to explore differences in heavier weight trajectories between children from immigrant and US-born families.

Legumes and pulses - a scoping review for Nordic Nutrition Recommendations 2023.

Consumption of legumes and pulses is associated with various health outcomes. Therefore, when updating the Nordic Nutrition Recommendations (NNR), summarizing the best available evidence on key health outcomes regarded as relevant for the Nordic and Baltics related to the consumption of legumes was essential. The aim of this scoping review was to evaluate the updated evidence on the effect of the consumption of legumes and pulses on various health outcomes, as well as their dose-response relationship in updated systematic reviews and meta-analyses. The scoping review is built on a de novo systematic review published in 2023 and additional searches on the consumption of legumes and pulses and its various health outcomes, including cardiovascular disease (CVD), cancer, type 2 diabetes, and obesity. Current available evidence shows that the consumption of legumes and pulses is associated with a lower risk of several cancers (evidence: low-moderate), and lower all-cause mortality (evidence: moderate). The associations with CVDs are neutral or inverse, with studies generally showing favourable changes in biomarkers for CVDs. Legume consumption is associated with a lower risk of obesity (evidence: low). For type 2 diabetes, no association was found with incidence, but trials on consumption of legumes and pulses and biomarkers generally indicated protective effects. Overall, the current evidence supports dietary recommendations to increase the consumption of legumes and pulses.

Abstract P193: Sex Moderates Diet Quality Differences in Integrated Collaborative Care for Comorbid Obesity and Depression: Post-Hoc Analysis of the Research Aimed at Improving Both Mood and Weight Randomized Clinical Trial

Background: High-quality diets, such as the Dietary Approaches to Stop Hypertension (DASH), are associated with lower risk for obesity and obesity-related chronic diseases. It is unclear whether diet quality improves aside from reduced calories in evidence-based behavioral weight loss interventions. Objective: Leveraging data from the Research Aimed at Improving Both Mood and Weight (RAINBOW) randomized trial, the objective of this post hoc analysis is to investigate (1) whether the study intervention was associated with improved diet quality in adults with comorbid obesity and depression, compared to usual care; and (2) whether the associations were modified by sex. Methods: Participants completed 24-hour dietary recalls at baseline, 6, 12, 18, and 24 months. Dietary outcomes included the DASH score as the composite measure of diet quality and its components. Between-group differences in dietary outcomes were examined among 409 participants and by sex, using repeated-measures mixed-effects linear models. Results: Changes in DASH scores did not differ between the intervention and usual care control groups through 24 months in both women and men. Compared with controls, men in the intervention group had significantly decreased nut, seed, and legume intake at 6 (mean difference, -1.1; 95% CI, -1.9, -0.3 servings/day; P=0.01) and 12 months (-1.0; -2.0, -0.0 servings/day; P=0.048). Compared with controls, women in the intervention group had significantly decreased fruit and vegetable intake at 18 (-1.8; -2.9, -0.6 servings/day; P=0.002) and 24 months (-1.1; -2.2, -0.1 servings/day; P=0.03), and whole grain intake at 24 months (-0.5; -0.9, -0.1 servings/day; P=0.03), but increased percent calories from fat at 24 months (3.6; 0.6, 6.5; P=0.02). Conclusions: Diet quality not only did not improve in an effective behavioral weight loss intervention but deteriorated in women, in particular. These post-hoc findings warrant confirmation and may suggest that behavior change techniques targeting diet quality that are tailored to women and men need to be an explicit focus of behavioral weight loss interventions aside from caloric reductions.

Abstract P343: Diet Behaviors, Income, and Body Composition Among Diverse Adult Populations in the United States

Background: Dietary behavior and food components contribute to an increased risk of obesity development and other metabolic disorders across racial groups. Those with favorable healthy diet behaviors and higher incomes experience a lower risk of obesity. Little is known about the effects of diet behaviors and income on body composition among Hispanic and non-Hispanic Black men and women. As a step toward developing successful obesity interventions among minority populations, this study aimed to investigate associations and interactions among eating outside of the home, fast foods, and income with multiple measures of obesity. Method: Publicly available data from the 2017-2018 National Health and Nutrition Examination Survey (NHANES) for 3942 Hispanic, non-Hispanic White, and Black women and men were analyzed using two-way MANOVA and sample independent t-tests. Diet behaviors included eating foods outside of the home (FOH) and fast food (FF), while obesity measures included body mass index (BMI), percent of body fat (POF), and waist circumference (WC). Results: Adults were 20-80 years old, with a mean BMI of 25.1, SD=6.4 (men, 24.9; women, 25.2), showing healthy weight overall. On average, men were eating more FOH ( M =0.84, 95% CI: 0.59 to 1.08, p &lt;0.001, Cohen’s d =0.1) and FF ( M =0.57, 95% CI: 0.22 to 0.92, P &lt;0.001, Cohen’s d=0.2) than women; Black men were eating more FOH ( M =1.09, 95% CI: 0.61 to 1.58, p &lt;0.001, Cohen’s d =0.3) than Black women; and there were no significant mean differences on eating FF among Black men and Black women. Women with income &lt;$25000/year were eating more FF and had higher BMI (π 2 =0.013) and POF (π 2 =0.013, p &lt;0.05) than men. On average, Hispanic, White, and Black men were more likely to eat more FOH ( p &lt;0.001) than Hispanic, White, and Black women, and Hispanic and Black women with income &lt;$25000/year were eating more FF and FOH and had higher BMI and WC than Hispanic, White, and Black men ( P &lt;0.05). Conclusion: Understanding associations between diet behaviors, income, and obesity across sex differences and ethnic groups is important to address multilevel public health interventions for those in need of obesity treatment. Additionally, it is important for providers and health professionals to understand obesity risks that are unique by racial group when developing tailored intervention and prevention programs.
