Abstract 4146319: Racial Disparities and Driving Factors in the AHA's Life's Essential 8 Among American Adults: Insights from NHANES 2011-2020

Backgrounds: The AHA introduced "Life's Essential 8" (LE8) in 2022 as a comprehensive metric to facilitate detailed tracking and management of cardiovascular health (CVH) at the population level. However, the racial/ethnic differences in LE8, how these differences change over time, and the driving factors of LE8 in each subgroup remain unclear. Methods: We utilized data from the continuous NHANES from 2011 to 2020 to examine racial disparities and driving factors in the AHA's LE8 among American adults. To ensure national representation, appropriate weights were applied. Survey-weighted and age-standardized trends in LE8 scores by racial and ethnic groups were analyzed using generalized linear models (GLMs). To identify the driving factors—specific metrics influencing the LE8 overall score—we calculated z-scores for all components. Then we used the spider chart to visualize the driving factors. Results: A total of 13,915 adult were included, of whom the mean age is 47.9 ± 0.37 years, 6,612 (47.55%) were women, 3,485 (14.63%) were Hispanics, 5,335 (69.74%) were non-Hispanic Whites, 3,464 (10.82%) were non-Hispanic Blacks, and 1,631 (4.81%) were Asians. From 2011-2020, the LE8 scores did not change significantly overall and across all racial groups (all p-trend > 0.10, Figure 1 ). During the study period, racial/ethnic disparity persisted with Asian adults consistently having the highest LE8 scores and Black adults having the lowest scores. Notably, the lower LE8 scores in Black adults were primarily driven by lower scores of diet, blood pressure, and sleep health, whereas the higher LE8 scores in Asian adults primarily driven by higher scores of diet, nicotine exposure, and BMI. The LE8 scores in White adults were primarily driven by blood glucose and physical activity and the LE8 score in Hispanic adults were primarily driven by blood pressure ( Figure 2-A ). In 2017-2020 ( Figure 2-B ), Black adults had the lowest scores for all LE8 components, except for blood lipids. In contrast, Asian adults had the highest scores in diet, physical activity, nicotine exposure, and sleep health. Throughout the study period, the racial/ethnic disparity in LE8 score did not change significantly (all p >0.10). Conclusion: We found persistent racial disparities in cardiovascular health among U.S. adults, with Black adults having the lowest LE8 scores in almost all components. The driving factors for LE8 scores varied by racial subgroups, emphasizing the need for targeted interventions.

Relative validity of three diet quality scores derived from the Brief-type Self-administered Diet History Questionnaire and Meal-based Diet History Questionnaire in Japanese adults.

No study has validated questionnaires for assessing easily calculable diet quality scores in Japan. The Brief-type self-administered Diet History Questionnaire (BDHQ) is widely used to assess dietary intake in Japan, while the Meal-based Diet History Questionnaire (MDHQ) assesses dietary intake for each meal (breakfast, lunch, dinner and snacks) and overall dietary intake. This study examined the relative validity of the BDHQ and MDHQ for assessing three diet quality scores in Japanese adults. A total of 111 women and 111 men aged 30-76 years completed the web MDHQ and BDHQ, followed by 4-non-consective-day weighed dietary records. The diet quality scores examined included the Diet Quality Score for Japanese (DQSJ), Dietary Approaches to Stop Hypertension (DASH) score and Alternate Mediterranean Diet (AMED) score. The means of the three scores for overall diet from the BDHQ were not significantly different from those from the dietary records in both sexes, whereas those from the MDHQ were higher than those from the dietary records, except for the DASH and AMED in women. Pearson's correlation coefficients between both questionnaires and dietary records were 0·57-0·63 for DQSJ, 0·49-0·57 for DASH and 0·31-0·49 for AMED across both sexes and both questionnaires. For each meal, Pearson's correlation coefficients between the MDHQ and dietary records ranged from 0·01 (DASH for snacks in women) to 0·55 (DQSJ for breakfast in men), with a median of 0·35. This study showed that the ability of the BDHQ and MDHQ to rank individuals was good for DQSJ and DASH and acceptable for AMED.

Examining the association of climate change worry and awareness of ecological footprint reduction behaviours with Mediterranean diet adherence and climate-friendly food choices

PurposeConsumers’ preferences for more sustainable dietary patterns and more climate-friendly foods can play a significant role in mitigating the effects of climate change. Accordingly, the present cross-sectional study aimed to examine the role of climate change worry and awareness of ecological footprint reduction behaviours in undergraduate consumers’ adherence to the Mediterranean diet and climate-friendly food choices.Design/methodology/approachThis cross-sectional study was carried out with 600 healthy undergraduate students, including 255 (42.5%) males and 345 (57.5%) females. They completed the climate change worry scale, the awareness scale for reducing ecological footprint and the Mediterranean diet adherence scale. In addition, participants’ climate-friendly diet scores (CFDS) were calculated to evaluate climate-friendly food choices. Data were analysed using SPSS software.FindingsLinear regression models indicated that climate change worry was positively associated with adherence to the Mediterranean diet (β = 0.121, p = 0.003) and CFDS (β = 0.087, p < 0.001). Similarly, a positive association was observed between the awareness of ecological footprint reduction behaviours and adherence to the Mediterranean diet (β = 0.179, p < 0.001) and CFDS (β = 0.098, p < 0.001).Research limitations/implicationsThe results may indicate that worry about climate change and awareness of ecological footprint reduction behaviours can promote higher adherence to the Mediterranean diet and more climate-friendly food choices, but the observed associations do not imply causality, and further studies are required to determine whether causal links exist.Originality/valueThis study examined the relationships between climate change worry, awareness of ecological footprint reduction behaviours, adherence to the Mediterranean diet and climate-friendly food choices in a single study on undergraduate students.

Abstract 4134379: Mediterranean-Style Diet and Adverse Pregnancy Outcomes by Race and Overweight or Obesity Status in the Boston Birth Cohort

Introduction: Mediterranean-style diet (MSD) is associated with a lower risk of cardiovascular and metabolic diseases. However, the association of MSD during pregnancy with adverse pregnancy outcomes (APOs) among different racial and ethnic groups and overweight or obesity (OWO) status remains unclear. Question: We examined if MSD during pregnancy is protective for developing any APO and individual APOs in a large cohort of racially and ethnically diverse, urban, low-income women. Methods: Among 8,511 patients in the Boston Birth Cohort (mean age 28.2±6.5 yrs), 47% were non-Hispanic Blacks and 28% were Hispanics. Among 4,343 (51%) with pre-pregnancy OWO status, 25% Black and 12% Hispanic women developed any APO (Figure 1). Individual Mediterranean-style diet score (MDS) was based on maternal diet intake during pregnancy via food frequency questionnaire interviews at 24-72 hours postpartum. Results: Increase in the MDS by one standard deviation was inversely associated with any APO (aOR, 0.86 [95% CI, 0.82–0.90]), preeclampsia or eclampsia or HELLP (aOR, 0.89 [95% CI, 0.82–0.97]), gestational diabetes (aOR, 0.88 [95% CI, 0.81–0.95]), preterm birth (aOR, 0.90 [95% CI, 0.86–0.95]), and low birth weight (aOR, 0.87 [95% CI, 0.83–0.92]) (Table 1). In the subgroup analysis, higher adherence to MSD was associated with lower odds of developing, preeclampsia or eclampsia or HELLP, low birth weight, and preterm birth in Black women with or without OWO. The benefit of MDS was also observed for gestational diabetes in Hispanic women with OWO (Figure 2). Conclusion: Greater adherence to MSD during pregnancy is associated with a lower risk of composite APOs, with benefits varying across types of APOs, racial/ethnic groups, and OWO status.

Trends in Toddler Diet Quality in the United States: 1999 to 2018.

Diet quality has improved over time for US adults and youth aged ≥2 years. Trends over time and disparities in the diet quality of toddlers 12 through 23 months old have not been documented. Our objective was to investigate the direction and magnitude of toddler diet quality trends from 1999 to 2018 overall and by household socioeconomic status. This serial cross-sectional analysis of National Health and Nutrition Examination Survey (NHANES) data was performed with 2541 toddlers from 10 NHANES cycles from 1999 to 2018. Dietary intake was measured by NHANES study staff using proxy-reported 24-hour recalls. Healthy Eating Index-Toddlers-2020 total scores (0-100 points, higher scores indicate healthier diets) and component scores were calculated from the 24-hour dietary recalls using the population ratio method. Multivariable linear regression was used to evaluate the association between time in years (measured as the midpoint of each NHANES cycle) and diet quality. Toddler diet quality improved significantly from 1999 to 2018 (P < .001), from 63.7 points on average in 1999-2000 to 67.7 points in 2017-2018. A significant positive linear trend in total diet quality was observed for all socioeconomic status groups (P < .05). Several dietary component scores improved, as follows: Whole Fruits (P < .001), Whole Grains (P = .016), Fatty Acids (P = .002), Refined Grains (P = .009), and Added Sugars (P < .001). Scores did not significantly change for Total Fruit, Total Vegetables, Greens and Beans, Dairy, Total Protein Foods, Seafood and Plant Proteins, Sodium, or Saturated Fats. From 1999 to 2018, toddler diet quality improved significantly, but mean scores still fell short of dietary guidance.

The relationship between the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet and metabolic health status in adolescents with overweight and obesity: results from a cross-sectional study in Iran.

Few studies investigated the association between Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet and metabolic health status, particularly among adolescents. The present study was designed to investigate the association of MIND diet with metabolic health status in Iranian adolescents with overweight/obesity. This cross-sectional study was done among 203 adolescents with overweight/obesity (12-18 years) in Isfahan, Iran. A validated FFQ was applied to collect dietary intakes. Anthropometric indices and blood pressure were also measured by standard procedures. Fasting blood samples were obtained to determine serum insulin, glucose and lipid profile. To categorise participants as being with metabolically healthy overweight/obesity (MHO) or metabolically unhealthy overweight/obesity (MUO), two methods including International Diabetes Federation (IDF) criteria and IDF plus Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) were applied. Participants had a mean age of 13·98 years and 50·2 % of them were girls. In fully adjusted models, participants with highest MIND diet adherence had lower odds of MUO status based on IDF (OR = 0·20; 95 % CI 0·08, 0·51) and IDF/HOMA-IR (OR = 0·22; 95 % CI 0·08, 0·59) criteria. Stratified analyses revealed that this association was stronger among girls and was only significant among individuals with overweight. An inverse association was also found between MIND diet score and odds of hyperglycaemia and insulin resistance (IR). Higher MIND diet adherence was associated with lower odds MUO in adolescents with overweight/obesity. Inverse associations were also found between MIND diet and odds of hyperglycaemia and IR. Future longitudinal prospective studies are necessary to confirm our results.

Associations of various healthy dietary patterns with biological age acceleration and the mediating role of gut microbiota: results from the China Multi-Ethnic Cohort study.

To investigate the associations between dietary patterns and biological aging, identify the most recommended dietary pattern for coping with biological aging and explore the potential mediating role of gut microbiota in less-developed ethnic minority regions (LEMRs). This prospective cohort study included 8288 participants aged 30-79 years from the China Multi-Ethnic Cohort study (CMEC). Anthropometric measurements and clinical biomarkers were utilized to construct biological age based on Klemera and Doubal's method (KDM-BA) and KDM-BA acceleration (KDM-AA). Dietary information was obtained through the baseline food frequency questionnaire (FFQ). Six dietary patterns were constructed: plant-based diet index (PDI), healthful plant-based diet index (hPDI), unhealthful plant-based diet index (uPDI), healthy diet score (HDS), Dietary Approaches to Stop Hypertension (DASH), and alternative Mediterranean diets (aMED). Follow-up adjusted for baseline analysis were employed to assess the associations between dietary patterns and KDM-AA. Additionally, quantile G-computation was utilized to evaluate the significant beneficial and harmful food groups. In the subsample of 764 participants with gut microbiota data obtained through 16S rRNA gene sequencing, we used causal mediation model to explore the mediating role of gut microbiota in the associations between dietary patterns and KDM-AA. The results showed that all dietary patterns were associated with KDM-AA. Transitioning from non-compliance to compliance, DASH exhibited the strongest negative association with KDM-AA [β = -0.91, 95%CI (-1.19, -0.63)]. The component analyses revealed that tea and soybean products were the significant beneficial food groups, while salt, preserved vegetables, red and processed meats were identified as the major harmful food groups. In mediation analysis, the decreased abundance of Synergistetes phylum and Pyramidobacter genus possibly mediated the negative associations between plant-based diets and KDM-AA (5.61%-9.19%). Overall, healthy dietary patterns, especially DASH, are negatively associated with biological aging in LEMRs. The Synergistetes and Pyramidobacter may mediate the associations between plant-based diets and biological aging. Developing appropriate strategies may promote healthy aging in LEMRs.

Relationship between Diet-Related Inflammation and Hospitalization Risk and Disease Severity in Patients with COVID-19

Background: Increased serum concentrations of inflammatory biomarkers in patients indicate a strong association between COVID-19 and inflammation. However, the association between diet-related inflammation and COVID-19 has been less investigated. The aim of this study is to investigate whether the inflammatory scores of the diet are associated with the severity of COVID-19 disease and the probability of hospitalization of patients. Methods: The authors conducted a cross-sectional study involving 141 patients with COVID-19. The empirical dietary inflammatory pattern (EDIP) and dietary inflammation scores (DIS) were calculated based on a 147-item semi-quantitative food frequency questionnaire. The association between serum levels of inflammatory biomarkers and diet-related inflammation was also investigated. Results: 74 inpatients and 87 outpatients participated in this study. Higher DIS scores were significantly associated with an increased risk of COVID-related hospitalization (Tertile3 vs. tertile1: OR = 3·62; 95 % CI 1·43 to 9·14, P=0·008 after fully adjustment). This association with EDIP was also observed, but it was not significant. Conclusion: The data from this provide evidence that a pro-inflammatory diet was associated with higher risk of hospitalization due to high severity of COVID-19.

Television viewing, oxidative stress, and kidney stone risk in males: a cross-sectional study with mediation analysis of the NHANES data (2011-2018 years).

To explore the association between television viewing time (TV-hours) and dietary oxidative balance score (DOBS) with the kidney stone risk in males. We analyzed age, poverty to income ratio, race, education, hypertension, diabetes, smoke, alcohol use, triglycerides, TV-hours, and DOBS data in the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018. Multivariable logistic regression was uesd to evaluate the associations between TV-hours, lifestyle OBS (LOBS), DOBS, Total OBS (TOBS), and the risk of kidney stones. Interaction terms between subgroup measures were used to test for effect modification across subgroups. Mediation analysis was performed to explore the mediating effect of DOBS on the association between TV-hours and kidney stones. The restricted cubic spline (RCS) was applied to describe dose-response relationships between TV-hours and risk of kidney stones as well. The study included 4167 males aged 20 and older, including 417 patients with kidney stones. The results showed that five or more TV-hours a day was associated with a higher risk of kidney stones [odds ratio (OR) = 1.16, (95% CI: 1.04-1.29), p = 0.01], and higher DOBS level was associated with a lower risk of kidney stones [OR = 0.97, (95% CI: 0.95-0.99), p = 0.004]. This association was remarkably consistent across TV-hours subgroups by age, race, alcohol use, hypertension and diabetes. According to the mediation analysis results, prolonged TV-hours is associated with an increased risk of kidney stones, this association is not mediated by DOBS. In other words, the impact of TV-hours on kidney stones risk is mainly a direct effect. When TV-hours is more than 2hours, the odds ratio began to be greater than 1. Overall, TV-hours was positively associated with kidney stones in males, whereas low DOBS was associated with kidney stones in males. This study suggests that an antioxidant diet and reduced television viewing time may be effective measures to prevent kidney stones in males.

Ultra-processed food consumption is associated with the acceleration of biological aging in the Moli-sani Study

BackgroundHealthy diets have been inversely associated with biological aging. However, the nutritional content is only one aspect of the overall food health potential, and more recently, increasing attention has been paid to nonnutrient food characteristics, such as food processing. ObjectivesTo examine the association of ultra-processed food (UPF) consumption with biological aging measured by circulating blood biomarkers. MethodsCross-sectional analyses were conducted on 22,495 participants enrolled in the Moli-sani Study (2005–2010, Italy). Food intake was assessed by a 188-item food frequency questionnaire. UPF was defined according to the Nova classification and calculated as the ratio (weight ratio; %) between UPF (g/d) and total food eaten (g/d). Diet quality was assessed by the Mediterranean Diet Score (MDS; ranging 0–9). A deep neural network approach based on 36 circulating biomarkers was used to compute biological age (BA), and the resulting difference (Δage = BA − chronological age)—an index of biological aging—was tested as dependent variable in multivariable linear regression analyses including known risk factors. ResultsThe mean Δage in this population was −0.70 (standard deviation ±7.70) years. In multivariable-adjusted analyses, higher intake of UPF was associated with accelerated Δage [β = 0.34 years; 95% confidence interval (CI): 0.08, 0.61 for the last fifth compared with the first). This association was not linear (P value for overall association <0.001; P value for nonlinearity = 0.049). Inclusion of the MDS into the model slightly attenuated this association by 9.1% (β = 0.31 years; 95% CI: 0.04, 0.59). ConclusionsA diet rich in UPF was associated with an acceleration of biological aging in a large sample of Italian adults. The poor nutritional composition of highly processed foods weakly accounted for this association, suggesting that biological aging could be adversely influenced by nonnutrient characteristics of these foods.

Relationship between Low Carbohydrate Diet and Postpartum Anxiety and Depression: Iranian Maternal and Child Health Cohort Study

Introduction: Postpartum depression, a form of depression, is a relatively common but serious medical condition that occurs following the birth of a baby. This study aimed to determine the relationship between the carbohydrate diet and the occurrence of anxiety and postpartum depression symptoms in women participating in the initial phase of the Maternal and Child Health Cohort Study, Yazd, Iran. Methods: This study was conducted on the data of 1028 pregnant women from the Yazd Maternal and Child Health Cohort Study. The study tools were food frequency questionnaire (FFQ) and postpartum depression questionnaire. Data related to dietary intake at the beginning of the study were collected in the first visit after pregnancy diagnosis and data related to depression in the second month after delivery. Carbohydrate intake score was calculated for each person according to summing up assigned scores to deciles of percentages of energy from macronutrients. Multivariable logistic regression models were used to estimate the odds ratio (ORs) and 95% confidence interval (CI) of postpartum depression and anxiety across quartiles of low carbohydrate diet scores. Results: Based on the multivariable-adjusted model, there was no significant association between low carbohydrate diet score and odds of postpartum depression (P=0.08). However, multivariable-adjusted model significantly indicated an association between low carbohydrate diet score in second tertile and the odds of postpartum anxiety (P=0.02) (OR: 0.36, 95% CI: 0.15-0.86). Conclusion: After adjusting the confounders, women in the second tertile of low carbohydrate diet score might have 64% lower chance of depression versus those in the first quartile. While low or high carbohydrate intake does not affect postpartum anxiety and depression, moderate carbohydrate intake might be anxiety protective.

Mediterranean diet and atrial fibrillation: a case-control study from China.

The aim of this study was to assess the association between adherence to Mediterranean diet and the presence of atrial fibrillation (AF) in a Northern Chinese population. This study was a single center, case-control study. A total of 952 low risk participants in Beijing Anzhen Hospital from 2016 to 2021 were collected, including 476 patients with first diagnosed of atrial fibrillation and 476 age and sex matched controls. According to the food frequency questionnaire (FFQ), the alternate Mediterranean diet score (AMED) was calculated, which was 0-9 points, indicating the adherence to the Mediterranean diet from low to high. The average age of the participants was 57.6 ± 9.1 years old, and 70.2% were men. After analyzing every component of AMED, vegetable consumption shows a negative correlation with the risk of AF, whereas alcohol consumption demonstrates a positive correlation with it (OR = 0.61, 95% CI 0.44-0.80, p < 0.001; OR = 1.99, 95% CI 1.48-2.58, p < 0.001). All patients were grouped according to AMED score. A significant inverse association between AMED and the risk of AF was observed. Compared with participants with AMED<4, the multivariable-adjusted ORs of AF were 0.75 (95% CI 0.55-1.06) for AMED 4-5 and 0.61 (95% CI 0.43-0.89) for AMED ≥6, with a trend in risk (p = 0.008). Results were consistent in stratified analyses of gender, age, BMI and smoking. The Mediterranean diet was inversely associated with the risk of AF in this Northern Chinese population.

A Mediterranean dietary pattern intervention does not improve cardiometabolic risk but does improve quality of life and body composition in an Aotearoa New Zealand population at increased cardiometabolic risk: A randomised controlled trial.

To test if a New Zealand food-based Mediterranean diet (NZMedDiet) with behavioural intervention improves cardiometabolic health and wellbeing. A randomised controlled trial comparing 12 weeks of the NZMedDiet to usual diet in participants with increased cardiometabolic risk (metabolic syndrome severity score [MetSSS] > 0.35). The intervention group was provided with food and recipes to meet 75% of their energy requirements, supported by a behavioural intervention to improve adherence. The primary outcome measure was (MetSSS) after 12 weeks. Two hundred individuals with mean (SD) age 49.9 (10.9) years of which 62% women were enrolled with their household/whānau. After 12 weeks, the mean (SD) MetSSS was 1.0 (0.7) in the control (n = 98) and 0.8 (0.5) in the intervention (n = 102) group; estimated difference (95% confidence interval [CI]) of -0.05 (-0.16 to 0.06), p = 0.35. The Mediterranean diet score (PyrMDS) was greater in the intervention group 1.6 (1.1-2.1), p < 0.001, consistent with a change to a more Mediterranean dietary pattern. Weight reduced in the NZMedDiet group compared with control (-1.9 kg [-2.0 to -0.34]), p = 0.006 and wellbeing, assessed by the SF-36 quality of life questionnaire, and improved across all domains. For example, the physical component summary score difference (95% CI) was 4.0 (2.4-5.7), p < 0.001, and the mental component summary score difference was 3.0 (0.7-5.2), p = 0.01. In participants with increased cardiometabolic risk, food provision with a Mediterranean dietary pattern and a behavioural intervention did not improve metabolic risk scores but was associated with reduced weight and improved quality of life.

Determinants of nutrition status among adolescents in selected secondary schools in rural Kanungu district Uganda

Background: Adolescence, the time between childhood and adulthood, often considered relatively healthy stage of life remain highly vulnerable to malnutrition. One crucial first step in reducing teenage malnutrition may be to attend to their dietary needs. This study examined the determinants of nutrition status among secondary school adolescents in the Kanungu district, Uganda. Methods: A school-based cross-sectional analytical study was employed in this study where both qualitative and quantitative methods of data collection were used for triangulation purposes. A multi-stage random sampling method was applied to obtain the study respondents. The Cochran formula was utilized to obtain 340 study respondents. Results: More than a quarter (37.1%) of the study respondents had malnutrition. Households that were father-headed (OR=1.8,95%CI=1.03-3.20), having met the recommended number of meal frequency (OR=2, 95%CI=1.13-3.44), being aware of healthy dietary habits (OR=2.2, 95%CI=0.29-0.71), having a small household size of 1-4 members (OR=4.3, 95%CI=2.38-7.83) and being employed (OR=2.1, 95%CI=1.17-3.93) increased the odds of having a normal nutrition status while having a primary level of education (OR=3.6, 95%CI=0.11-0.68), having an inadequate dietary score (OR=2.1,95%CI=0.28-0.76) reduced the odds of having a normal nutrition status. Conclusions: From this study, malnutrition was a public health concern. Households that were father-headed, being aware of healthy dietary habits, having a small household size of 1-4 members, and being employed increased the odds of having a normal nutrition status while having a primary level of education, having an inadequate dietary score reduced the odds of having a normal nutrition status.

The association between low carbohydrate dietary score (LCDS) and cardiovascular risk factors: results from the Shiraz Heart Study (SHS)

BackgroundCardiovascular disease (CVD) is a major cause of death and recent studies have highlighted the potential role of dietary carbohydrate indices in cardiovascular health. Given the controversial results in this field, the aim of this study was to investigate the association between low carbohydrate dietary score (LCDS) and CVD risk factors in a population of Iranian adults.MethodsThis cross-sectional study was conducted within the framework of the Shiraz Heart Study (SHS) including 1982 adults. The validated 168 items food frequency questionnaire (FFQ) was used to assess participants’ dietary intakes. To investigate the association between LCDS and cardiometabolic risk factors, logistic regression, was conducted.ResultsDuring 5 years of follow-up, a total of 1982 adults, with a mean age of 53.07 ± 8.38 years, were included to the analysis. The adjusted model based on known confounding factors (age, sex, smoking, physical activity, energy intake and body mass index) revealed a significant decrease in a body shape index (ABSI) (OR = 0.70, 95% CI= (0.50 to 0.98), P = 0.038) comparing highest LCDS tertile vs. the reference. In contrast, risk of hypertension (HTN), body mass index (BMI), waist-hip ratio (WHR), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), atherogenic index of plasma (AIP), and fasting blood sugar (FBS) were not significantly associated with LCDS.ConclusionCurrent findings suggest that adherence to a low carbohydrate diet reduces ABSI, a main indicator of central obesity.

Onset of cognitive impairment, diet quality and adherence to dietary guidelines over 12 years: the Personality and Total Health Cohort Study.

Around 55 million people worldwide live with dementia, and more are expected due to population ageing. We aimed to investigate associations between healthy diet and mild cognitive impairment and dementia in 1753 older adults aged 60-64 from the PATH (Personality and Total Health Through Life Cohort) study. Healthy diet was defined by the Mediterranean-DASH diet Intervention for Neurological Delay (MIND) and two dietary guideline quality scores (Dietary Guideline Index (DGI) and Index Diet Quality (IDQ)), which were calculated from baseline FFQ. Higher dietary scores indicated higher diet quality. Incidence of Alzheimer's disease/vascular dementia (National Institute of Neurological Disorders criteria) and mild cognitive impairment (Winbald criteria) was assessed after 12 years of follow-up using validated questionnaires with nominated proxies. Logistic regression explored associations between dietary scores and cognitive function, adjusting for demographics, lifestyle factors and medical preconditions. Adjusted logistic regression comparing the per unit linear increase in diet scores showed MIND (OR = 0·82, 95 % CI = 0·68, 0·99), but not DGI (0·99 (0·97, 1·00)) or IDQ (1·12 (0·95, 1·32)), was significantly associated with lower odds of developing cognitive impairment. In conclusion, a healthier neuroprotective dietary pattern is associated with better cognitive function over time, whereas dietary patterns generated from general dietary guidelines did not show a significant association. Further research and well-designed clinical studies are needed to determine the effects of the MIND diet on cognitive impairment in older adults without a family history of dementia.

Comparison of diet quality indices for predicting metabolic syndrome in Iran: cross-sectional findings from the persian cohort study

BackgroundThe metabolic syndrome (MetS) comprises metabolic irregularities, including hypertension and central obesity, which are influenced by genetic, metabolic, environmental, and dietary factors. As diet and lifestyle are risk factors for MetS, it is important to know which diet quality index better predicts MetS. The aim of this study is to compare the ability of different diet quality indices in predicting MetS and to identify the most effective one.MethodsThis cross-sectional study involved 5,206 participants aged 35 to 70 engaged in the Prospective Epidemiological Research Study in Iran (PERSIAN) cohort. Assessment of one year’s food intake via a validated 134-item semi-quantitative food frequency questionnaire (FFQ) facilitated the calculation of adherence to five diet quality indices: Dietary Approaches to Stop Hypertension (DASH), Mediterranean, Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND), Dietary Inflammatory Index (DII), and Diet Quality Indices (DQI). While bivariate Pearson correlation and binary logistic regression aided in identifying the strongest correlation and predictor for MetS among the indices.ResultsThis study showed a significant association between adhering to the DASH diet score, Mediterranean diet score, MIND diet score, DII score, and DQI score, and the odds of developing MetS (OR: 0.94, (95% CI: 0.93–0.95), OR: 0.85, (95% CI: 0.81–0.89), OR: 0.84, (95% CI: 0.80–0.89), OR: 1.22, (95%CI: 1.11–1.34), OR: 0.95, (95%CI 0.94–0.96) respectively). Therefore, with each unit increase in DASH diet score, Mediterranean diet score, MIND diet score, DII score, and DQI score, the odds of MetS was reduced by 5.4%, 14.5%, 15.6%, 22%, 5%, respectively. All the indices were correlated with the intake of most of the micronutrients, with the strongest correlations being observed in the DII. DASH diet score aligned with the most favourable MetS biomarker risk, while DII score primarily associated with MetS and could be considered as a predictor for MetS.ConclusionThe present study’s findings reveal that between all these five diet quality indices, the DASH diet score correlates strongly with a favourable biomarker risk profile, while the DII score is predominantly linked to MetS.

Diet quality trajectories from infancy to age 18 and their association with diet quality at age 26

Abstract Background and objectives Dietary habits during childhood and adolescence show strong stability. However, no studies have investigated dietary trajectories from infancy to adulthood. We therefore aimed to 1) identify diet quality trajectories from age 1 to 18 years and 2) explore how trajectories are associated with diet quality at age 26 years. Methods The study included 620 individuals from the Special Turku Coronary Risk Factor Intervention Project (STRIP), started in infancy (n = 1062). Food and nutrient intake was assessed annually from age one to age 18, and again at age 26 using 4-day food records. A food-based diet score (range 0-33) was calculated to indicate diet quality. Group-based modelling was used to model trajectories of diet quality between the ages of 1 and 18 years. Linear regression analyses were used to investigate associations between the diet quality trajectory groups and diet quality at age 26 years. Results By the age of 18, we found five diet quality groups: 1) low (19% of participants) with a mean diet score of 12 points, 2) decreasing (25%) with a mean diet score of 15 points, 3) increasing (15%) with a mean diet score of 16 points, 4) intermediate (31%) with a mean diet score of 18 points, and 5) high (10%) with a mean diet score of 22 points. The diet quality trajectory groups were associated with 0.4 (decreasing), 2.5 (medium), 3.8 (increasing) and 4.1 (high) points higher diet scores at age 26 compared to the low diet quality trajectory group (p &amp;lt; 0.001 for all). Discussion Five distinct dietary trajectories were found from infancy to late adolescence, with a clear difference between the groups with the lowest and highest diet quality. However, the differences in diet quality levelled out by the age of 26 years. Our results suggest that diet quality established already in childhood moderately predicts diet quality into adulthood. Key messages • Diet quality established in childhood moderately predicts diet quality in young adulthood. • Five distinct dietary trajectories were found from infancy to late adolescence, with a clear difference between the groups with the lowest and highest diet quality.

Effectiveness of Internet + E-Coach chronic disease management on blood glucose, lipid levels, liver function, and quality of life in patients with chronic diabetic retinopathy: a comparative study

ObjectiveThis study aims to explore the effect of Internet + E-Coach chronic disease system intervention on fasting blood glucose (FPG), 2-hour postprandial blood glucose(2hPG), fasting serum insulin (FINS), triglyceride (TG), alanine transaminase (ALT) and quality of life in patients with chronic diabetic retinopathy.Methods208 patients with chronic diabetic retinopathy who were treated in the hospital from March 2021 to March 2023 are chosen and separated into two groups by random number Table 104 patients in the control group received routine continuous intervention, and the research group received Internet + E-Coach chronic disease system intervention. The cognition of disease related knowledge, blood related indicators inflammatory factor levels and improvement of life quality between the two groups before intervention, 6 and 12 months after intervention were compared.ResultsBefore the intervention, the comparison between the two groups in disease related knowledge scores, blood glucose, blood lipid, liver function indicators, inflammatory factor, and low vision quality of life scale (CLVQOL) scores was with P > 0.05. After 6 and 12 months of intervention, the research group had significantly higher scores for basic blood glucose intervention, healthy diet, reasonable exercise, and correct medication use compared to the control group (P < 0.05). FPG, 2hPG, TG and ALT in the research group were lower than those in the control group. FINS were higher in the control group, with P < 0.05. Interleukin-6 (IL-6), tumor necrosis factor (TNF-α), and hypersensitive C-reactive protein (Hs-CRP) in the research group were obviously lower than those in the control group (P < 0.05). The scores of far vision, movement and light perception, adjustment ability, reading and fine work, and daily living ability in the research group were higher than those in the control group, with P < 0.05.ConclusionThe intervention of Internet + E-Coach chronic disease system can improve the knowledge of chronic diabetic retinopathy patients about their own condition, stabilize the levels of blood sugar, blood lipid and liver function indicators, reduce the inflammatory reaction of the body, and improve the quality of life.

Correlations Between Dietary Magnesium Consumption and Magnesium Depletion Score in Relation to Parkinson's Disease: A Population-Based Study.

The purpose of the study was to examine whether magnesium (Mg) depletion score (MDS) and dietary Mg intake are associated in adults with the risk of developing Parkinson's disease (PD). In this study, we analyzed data from the National Health and Nutrition Examination Survey (NHANES), which included 20,010 adults aged over 40 years old. To evaluate the linear association between PD and dietary intake of Mg or MDS, we conducted weighted logistic regression for univariate analysis and multivariate linear regression models. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using logistic regression models. A restricted cubic spline (RCS) was drawn to visualize the nonlinear relationship between MDS/dietary Mg intake and PD. In addition, we examined the variations in the relationship between MDS and PD across different confounding factors of the association using subgroup analysis. There were 240 PD cases (1.2%), and 19770 non-PD were included in the study. We found that a higher MDS was associated with an increased risk of PD after adjusting for covariates (OR per 1-unit increase, 1.47; 95% CI, 1.16-1.86). There is insufficient evidence to support a significant statistical association between Mg intake and the risk of PD. According to nonlinear regression, high MDS was associated with higher odds of PD and lower odds of PD above 250 mg/day intake of Mg. It has been shown that Mg bioavailability may be negatively associated with PD as measured by MDS. MDS is a potential method for screening the population with PD. Maintaining adequate Mg status may be important for PD prevention.
