Adherence to diet with higher dietary diabetes risk reduction score is associated with reduced risk of type 2 diabetes incident in Iranian adults

BackgroundThe Dietary diabetes risk reduction score (DDRRS) has recently been considered by researchers as a diet quality index to predict the risk of chronic diseases, such as type 2 diabetes (T2D). In this study, we aimed to assess the association of DDRRS with T2D risk in Iranian adults.MethodsSubjects aged ≥ 40 years without T2D (n = 2081) were selected for the current study from participants of the Tehran Lipid and Glucose Study (2009–2011) and followed for a mean of 6.01 years. We used the food frequency questionnaire to determine the DDRRS that is characterized by eight components, including higher consumption of nuts, cereal fiber, coffee, and polyunsaturated to saturated fat ratio and lower consumption of red or processed meats, trans fats, sugar-sweetened beverages, and high glycemic index foods. The multivariable logistic regression analysis was used to determine the odds ratio (ORs) and 95% confidence interval (CI) of T2D across the DDRRS tertiles.ResultsThe mean ± SD age of individuals was 50.4 ± 8.2 years at baseline. The Median (25–75 interquartile range) DDRRS of the study population was 24(22–27). During the study follow-up, 233(11.2%) new cases of T2D were ascertained. In the age and sex-adjusted model, the odds of T2D were decreased across tertiles of DDRRS (OR = 0.68; 95%CI: 0.48–0.97, P for trend = 0.037). Based on the multivariable-adjusted model, after controlling all potential confounders, the risk of T2D is reduced across tertiles of DDRRS (OR = 0.66; 95%CI: 0.44–0.98, P for trend = 0.047). Also, higher scores (lower consumption) of red and processed meat (OR = 0.59; 95%CI: 0.39–0.88, P = 0.012) and sugar-sweetened beverages (OR = 0.49; 95%CI: 0.32–0.76, P = 0.002) as DDRRS components were associated with decreased T2D incident.ConclusionsOur findings suggested that a diet with a higher score of DDRRS may be related to reducing the risk of T2D in Iranian adults.

Is Adherence to the Mediterranean Diet Associated with Eating Behaviour and Emotional Appetite in Young Women?

Introduction: This study aimed to evaluate the effects of adherence to the Mediterranean Diet (MD) on eating attitudes and emotional appetite in young females aged 18-24. Methodology: A cross-sectional study (n=306) was conducted on young females. A questionnaire including demographic characteristics, Eating Attitudes Test-26 (EAT-26), Emotional Eating Questionnaire (EMAQ), and International Physical Activity Questionnaire (IPAQ) was applied. Daily food consumption was obtained from the 24-hour- food records and used to calculate the Mediterranean Diet Quality Index (MAI). The researchers measured the body weight (kg) and height (cm). Results: Half of the participants (50.7%) have low adherence to the MD, moderate in 25.2%, and high in 24.2%. There is no statistical difference in MAI scores between EAT-26 groups (p>0.05). The dieting status was higher (28.2%) in the disordered eating tendencies group compared to the group without disordered eating tendencies (11.1%) (χ2 =12.490, p<0.001). The scores of the negative total scores were higher in the group with disordered eating risk (p=0.004). Conclusions: Young females’ low adherence to Mediterranean Diet might be associated with future health problems. No effect of MAI on disordered eating behavior was determined but EMAQ-negative sub and total scores were determined as a component of EAT-26. Early detection of diet quality and conditions associated with emotional eating disorders is thought to be important in preventing future health problems.

Diets of Men and Women in Rural Bangladesh Are Equitable but Suboptimal

BackgroundRecent evidence suggests that diet inequities between men and women may have diminished within rural Bangladeshi households. However, this has not been directly tested with appropriate physiologic adjustments and it is unclear whether changes have occurred across socioeconomic strata. Understanding intrahousehold dietary patterns at different points on the income and food-security distribution in rural Bangladesh—particularly, within ultrapoor and farm households—is important for appropriate design of gender-sensitive and nutrition-sensitive interventions, which often target these groups. ObjectiveUsing 2012 and 2016 data, we aimed to examine gender differences in diet quantity and quality among ultrapoor and farm households in rural Bangladesh. MethodsThe study used baseline 24-h dietary data from 2 randomized control trials conducted in rural Bangladesh: the Transfer Modality Research Initiative (ultrapoor households) and the Agriculture, Nutrition, and Gender Linkages project (farm households). Ordinary least squares regressions with household-level fixed effects tested for gender differences among constructed diet measures, such as caloric intake, caloric adequacy ratio, dietary diversity score, global diet quality score, and probability of consuming moderate or high levels of healthy food groups. ResultsIn both samples, on average, women consumed fewer calories than men in the same households but consumed near equal or more in reference to their caloric needs. Women scored <1% lower than men on diet quality indicators and showed similar probabilities to men of consuming healthy foods. Most men and women in both samples were calorically inadequate (>60%) and recorded poor diet quality scores that indicated high risk of nutrient inadequacy and chronic disease (>95%). ConclusionsIn both ultrapoor and farm households, although men record higher intake quantities and diet quality scores, the apparent male advantage disappear when energy requirements and the magnitudes of difference are considered. Diets of men and women in these rural Bangladeshi households are equitable but suboptimal.

Effects of dietary sugar restriction on hepatic fat in youth with obesity.

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in children. Like adults, children can develop the progressive form of NAFLD, nonalcoholic steatohepatitis (NASH), which is characterized by hepatic inflammation, often in the presence of fibrosis. Children with NAFLD are at higher risk of liver-related complications, metabolic dysfunction, and cardiovascular disease in adulthood. Many factors contribute to the escalating prevalence of NAFLD in the pediatric population, among which are an array of dietary patterns such as overnutrition, poor diet quality, and heavy consumption of fat and sugar, including fructose. Findings from an increasing number of epidemiological studies support a connection between high habitual sugar consumption and NAFLD, especially within the context of obesity, but these studies are not able to demonstrate whether sugar is a contributing factor or instead an indicator of an overall poor diet (or lifestyle) quality. To date, only four randomized controlled dietary interventions assessing the effects of sucrose/fructose restriction on hepatic fat fraction in youth with obesity have been published. The objectives of this review are to summarize the key findings from these dietary interventions to achieve a better understanding of the strength of the relationship between dietary sugar restriction and liver fat reduction, despite their inherent limitations, and to discuss the potential impact of weight loss and fat mass reduction on improvement in hepatic steatosis.

0235 Social Jetlag and Diet Quality Among US Young Adults

Abstract Introduction Young adults are among the populations with the lowest quality diets in the US, and poor sleep could be a contributing factor. Social jetlag, the lack of consistent sleep timing from weekdays to weekends, is also more common among young adults. Our objective was to examine associations between social jetlag and diet quality among US young adults, and to evaluate effect modification by sex or race/ethnicity. Methods The study population included 1,308 adults aged 20-39 who participated in the 2017-2018 National Health and Nutrition Examination Survey. Social jetlag was considered as ≥2-hour difference in sleep midpoint (median of bedtime and wake time) between weekends and weekdays. Diet quality was assessed with the Healthy Eating Index (HEI)-2015, which is comprised of 13 dietary components and ranges from 0 to 100 (higher scores=better diet quality). Scores were binned into three groups based on tertile cutoffs. Ordinal logistic regression analyses were utilized to evaluate the relationship between social jetlag and HEI-2015 scores as well as the individual HEI components, adjusting for age, sex, race/ethnicity, educational attainment, recent tobacco use and physical activity. Effect modification by sex and race/ethnicity were also considered. Results In the analytic sample, 31% of young adults had social jetlag. Overall, there were no associations between social jetlag and diet quality. However, interaction analysis revealed several associations were race-specific (P, interaction&amp;lt; 0.05). Among Black adults, social jetlag was associated with lower overall diet quality (OR = 0.4, 95% CI 0.2, 0.8; i.e., less likely to be in higher diet quality tertiles) and more unfavorable scores on total vegetables (OR = 0.6, 95% CI 0.3, 1.0) and added sugar (i.e., OR = 0.6, 95% CI 0.4, 0.9). For Hispanic adults, social jetlag was associated with higher intakes of sodium (OR=0.6, 95% CI 0.4, 0.9) However, White adults with social jetlag had higher intake of greens and beans (OR = 1.9, 95% CI 1.1, 3.2). Conclusion Within a nationally-representative sample of US young adults, social jetlag was related to certain indicators of lower diet quality among Black and Hispanic Americans.

Prevalence of functional gastrointestinal disorders in Italian children living in different regions: analysis of the difference and the role of diet

BackgroundFunctional Gastrointestinal Disorders (FGIDs) are common in pediatric age. AimsTo estimate the prevalence of FGIDs in Italian children and evaluate the impact of diet. MethodsHealthy children aged 4–18 years were recruited in a multicenter cross-sectional study. We evaluated their eating habits and the presence of FGIDs, using Rome IV criteria, 3-day food diaries and Mediterranean Diet Quality Index (KIDMED) questionnaires. ResultsSeven hundred forty subjects were enrolled:369 children aged 4–9 years (Group A), and 371 adolescents 10–18 years old (Group B). The overall prevalence of FGIDs was 26.4% in Group A and 26.2% in Group B, with a significant higher prevalence in females in both groups. The most frequent disorders were functional constipation, functional dyspepsia, and abdominal migraine. No significant difference in FGIDs prevalence was found between Northern and Southern Italy, despite significant variation in diet. In Group A there was a significant difference in KIDMED between North and South (5.3 ± 1 vs 6 ± 1.2, respectively; p = 0.001). A significant association between FGIDs and KIDMED was found in Group A (OR=0.83, p = 0.034), but not in Group B (OR=0.89, p = 0.166). ConclusionsFGIDs are common in Italian children, with a higher prevalence in females. Despite significant differences in dietary habits between North and South, FGIDs prevalence does not vary significantly.

How is healthy eating index-2015 related to risk factors for cardiovascular disease in patients with type 2 diabetes.

Cardiovascular disease (CVD) is the primary cause of mortality and disability among diabetes. The aim of this study is to evaluate how healthy eating index-2015 related to risk factors for cardiovascular disease in patients with type 2 diabetes. This cross-sectional study was conducted on 490 patients with type 2 diabetes in Tehran, Iran. The healthy eating index-2015 (HEI-2015) used as a diet quality indicator. Dietary intake was assessed by a valid and reliable semi-quantitative food frequency questionnaire (FFQ). Four indicators of CVD risk factor [Castelli risk index-1 and 2 (CRI-II), atherogenic index of plasma (AIP), cholesterol index (CI), and lipid accumulation of plasma (LAP)] were calculated. The anthropometric indices [a body shape index (ABSI), abdominal volume index (AVI), and body roundness index (BRI)] were computed. After adjusting for potential confounders, it is evident that participants in the highest tertile of HEI had a lower odds ratio of BRI (OR: 0.52; 95% CI: 0.29-0.95; p-trend = 0.03) and AIP (OR:0.56; 95% CI: 0.34-0.94; p-trend = 0.02). Also, HEI and CRI had a marginally significant negative relation (OR: 0.61; 95% CI: 0.38-1; p-trend = 0.05) in crude model, after adjusting the signification disappeared. In conclusion, our finding shows that more adherence to HEI reduces about 50% of the odds of AIP, BRI among diabetic patients. Further, large-scale cohort studies in Iran need to confirm these findings, including diabetic patients of various racial, ethnic backgrounds, body composition and different components of HEI.

The association between diet quality index-international and inflammatory markers in Iranian overweight and obese women.

The present study was conducted to evaluate whether there is a link between the diet quality index (DQI) and markers of systemic inflammation in Iranian overweight and obese women. This cross-sectional study included 200 Iranian overweight and obese women aged 18-48 years. The DQI-international (DQI-I) comprises four main components: variety, adequacy, moderation, and overall balance. Blood samples were collected in a fasted state to measure inflammatory markers. After adjusting for age, body mass index (BMI), physical activity, total energy intake, economic status, education, supplement intake, age of starting obesity, and history of body mass loss, a marginally significant negative association was observed between the homeostasis model assessment of insulin resistance (HOMA-IR) and the DQI-I (β: -0.015, 95% CI: -0.03, 0.000; p = 0.061). The results after adjustment showed that DQI-I has a negative association with high-sensitivity C-reactive protein (hs-CRP) concentrations (β: -0.031, 95% CI: -0.104, -0.031; p = 0.023). Furthermore, negative associations were observed between the adequacy component and levels of HOMA-IR (β: -0.025, 95% CI: -0.100, 0.047, p = 0.050) and hs-CRP (β: -0.615, 95% CI: -1.191, -0.020; p = 0.045). In addition, negative associations were found between transforming growth factor-β (TGF-β) and balance score (β: -6.270, 95% CI: -39.211, -3.661, p = 0.020), as well as HOMA-IR (β: -0.080, 95% CI: -0.202, -0.000, p = 0.041) and chemoattractant protein-1 (MCP-1) (β: -0.562, 95% CI: -11.414, -0.282, p = 0.021), with the various component. A marginally significant negative association between galectin 3 (Gal-3) and moderation score (β: -0.451, 95% CI: -1.171, 0.060, p = 0.060) was found. In addition, a marginally significant inverse association was also established between hs-CRP and variety score (β: -0.311, 95% CI: -0.970, 0.001, p = 0.052). The Receiver Operating characteristic (ROC) curve analysis demonstrated that DQI-I might better predict HOMA-IR with a cut point of 3.13 (AUC = 0.698, 0.511-0.699, p = 0.050). These findings showed that a higher adherence to diet quality and its components could probably be related to lowering the inflammatory markers considerably in overweight and obese women.

Interrogating Components of 2 Diet Quality Indices in Pregnancy using a Supervised Statistical Mixtures Approach

BackgroundThe Healthy Eating Index (HEI)-2015 and Alternative Healthy Eating Index (AHEI)-2010 evaluate diet holistically in pregnancy. However, it remains unclear how individual index components interact to contribute to health. ObjectivesTo evaluate associations of HEI-2015 and AHEI-2010 components with gestational length using traditional and novel statistical methods in a prospective cohort. MethodsPregnant women completed a 3-mo food-frequency questionnaire (FFQ) at median 13 wk gestation to calculate the HEI-2015 or AHEI-2010. Covariate-adjusted linear regression models evaluated associations of HEI-2015 and AHEI-2010 total scores and individual components (one at a time and simultaneously adjusted) with gestational length. Covariate-adjusted weighted quantile sum regression models evaluated 1) associations of HEI-2015 or AHEI-2010 components as mixtures with gestational length and 2) contributions of components to these associations. ResultsEach 10-point increase in HEI-2015 and AHEI-2010 total score was associated with 0.11 (95% CI: −0.05, 0.27) and 0.14 (95% CI: 0.00, 0.28) wk longer gestation, respectively. In individual or simultaneously adjusted HEI-2015 models, higher intakes of seafood/plant proteins, total protein foods, greens/beans, and saturated fats but lower intakes of added sugars and refined grains were associated with longer gestational length. For the AHEI-2010, higher intake of nuts/legumes and lower intake of sugar-sweetened beverages (SSBs)/fruit juice were associated with longer gestational length. Jointly, 10% increases in HEI-2015 or AHEI-2010 mixtures were associated with 0.17 (95% CI: 0.001, 0.34) and 0.18 (95% CI: 0.05, 0.30) wk longer gestational length, respectively. Seafood/plant protein, total protein foods, dairy, greens/beans, and added sugars were the largest contributors to the HEI-2015 mixture. Nuts/legumes, SSBs/fruit juice, sodium, and DHA/EPA were the largest contributors to the AHEI-2010 mixture. Associations were less precise but consistent in women with spontaneous labors. ConclusionsCompared to traditional methods, associations of diet index mixtures with gestational length were more robust and identified unique contributors. Additional studies could consider interrogating these statistical approaches using other dietary indices and health outcomes.

Adherence to dietary guidelines, and the risk of developing rheumatoid arthritis: results from a nested case-control study.

To examine the relationship between adherence to dietary guidelines and the risk of developing RA. Participants in the Malmö Diet and Cancer Study (MDCS) cohort diagnosed with RA were identified through register linkage and validated in a structured review. Four controls per case were selected, matched for sex, year of birth, and year of inclusion in the MDCS. Diet was assessed at baseline (1991-1996) using a validated diet history method. A Diet Quality Index (DQI) based on adherence to the Swedish dietary guidelines including intakes of fibre, vegetables and fruits, fish and shellfish, saturated fat, polyunsaturated fat, and sucrose, was used. The associations between the DQI and its components and the risk of RA were assessed using conditional logistic regression analysis, adjusting for total energy intake, smoking, leisure time physical activity and alcohol consumption. We identified 172 validated cases of incident RA in the cohort. Overall adherence to the dietary guidelines was not associated with the risk of RA. Adherence to recommended fibre intake was associated with decreased risk of RA in crude and multivariable-adjusted analyses, with odds ratios (ORs) 0.60 (95% CI 0.39, 0.93) and 0.51 (95% CI 0.29, 0.90), respectively, compared with subjects with non-adherence. Reaching the recommended intake level of dietary fibre, but not overall diet quality, was independently associated with decreased risk of RA. Further studies are needed to assess the role of different food sources of dietary fibre in relation to risk of RA and the underlying mechanisms.

Prevalence of Mental Health Problems Among University Students and Association With Body Mass Index (BMI) and Diet Quality

Introduction: Numerous factors contributed to the susceptibility of university students to develop mental health issues. Objective: This study aimed to assess the prevalence of mental health problems among International Islamic University Malaysia (IIUM) students and their relationships with diet quality and body mass index (BMI). Methods: A cross-sectional study was conducted among 104 students. The Depression, Anxiety, and Stress Scale (DASS-21) was used to assess students’ depression, anxiety, and stress levels. The Malaysian Healthy Eating Index (M-HEI) was used to assess diet quality. Spearman Rho was used to determine the relationships between variables. Results: Approximately 69.4% (n = 34), 71.4% (n = 35), and 48.9% (n = 34) of male students experienced moderate to extremely severe symptoms of depression, anxiety, and stress, respectively. In contrast, 85.4% (n = 47), 89.1% (n = 49), and 54.6% (n = 30) of female students had moderate to extremely severe symptoms of depression, anxiety, and stress, respectively. No correlations were found between diet quality and BMI with students’ mental health problems. For male students, there were negative significant associations reported between fat-rich foods (r = -0.447, p-value = 0.001) and sugar-rich foods (r = -0.332, p-value = 0.020) intake with depression; a positive significant relationship between fruit intake and anxiety (r = 0.284, p-value = 0.048); a positive relationship between fruit intake and stress (r = 0.300, p-value = 0.036); and a negative relationship between fat-rich foods and stress (r = -0.293, p-value = 0.041). Female students only had a significant negative correlation between fish intake and anxiety (r = -0.376, p-value = 0.005). Conclusion: No associations were found between diet quality, BMI, and mental health problems. A more profound comprehension of the connections between risk factors and mental health could lead to new intervention strategies.

Diet quality and anthropometric indices of patients undergone bariatric surgery: the prospective Tehran obesity treatment study

BackgroundPatients undergone bariatric surgery (BS) has long-term risks including decrease in diet quality, nutritional deficiencies and weight regain. This study focus on assessing dietary quality and food group components in patients one year after BS, the relationship between dietary quality score and anthropometric indices, and also evaluating the trend of body mass index (BMI) of these patients three years after BS.MethodsA total of 160 obese patients (BMI ≥ 35 kg/m2) were undergone sleeve gastrectomy (SG) (n = 108) or gastric bypass (GB) (n = 52), participated in this study. They were assessed for dietary intakes using three 24-hour dietary recalls one year after surgery. Dietary quality was assessed using food pyramid for post BS patients and healthy eating index (HEI). Anthropometric measurements were taken pre-surgery and 1, 2 and 3 years after operation.ResultsThe mean age of patients was 39.9 ± 11 years (79% female). The mean ± SD percentage of excess weight loss was 76.6 ± 21.0 one year after surgery. Intake patterns are generally (up to 60%) not consistent with the food pyramid. The mean total HEI score was 64 ± 12 out of 100. More than %60 of participants is exceeding the recommendations for saturated fat and sodium. The HEI score did not show significant relationship with anthropometric indices. The mean of BMI in SG group increased over three years of follow up, while in GB group, there were no significant differences in BMI during three years of follow up.ConclusionsThese findings showed that patients had not healthy pattern intake one year after BS. Diet quality did not show significant relationship with anthropometric indices. The trend of BMI three years after surgery was different based on surgery types.

Dietary Total Antioxidant Capacity, a Diet Quality Index Predicting Mortality Risk in US Adults: Evidence from the NIH-AARP Diet and Health Study.

Dietary total antioxidant capacity (TAC) is an index representing the total antioxidant power of antioxidants consumed via the diet. This study aimed to investigate the association between dietary TAC and mortality risk in the US adults using data from the NIH-AARP Diet and Health Study. A total of 468,733 adults aged 50-71 years were included. Dietary intake was assessed using a food frequency questionnaire. Dietary TAC from diet was calculated from antioxidants including vitamin C, vitamin E, carotenoids, and flavonoids, and TAC from dietary supplements was calculated from supplemental vitamin C, vitamin E, and beta-carotene. During a median follow-up of 23.1 years, 241,472 deaths were recorded. Dietary TAC was inversely associated with all-cause (hazard ratio (HR) for quintile 5 vs. quintile 1: 0.97, 95% confidence interval (CI): 0.96-0.99, p for trend < 0.0001) and cancer mortality (HR for quintile 5 vs. quintile 1: 0.93, 95% CI: 0.90-0.95, p for trend < 0.0001). However, dietary supplement TAC was inversely associated with cancer mortality risk only. These findings indicate that consuming a habitual diet high in antioxidants may reduce the risk of all-cause and cancer mortality and TAC from foods might confer greater health benefits than TAC from dietary supplements.

Fruit Juice Consumption, Body Mass Index, and Adolescent Diet Quality in a Biracial Cohort

Fruit juice consumption during childhood remains controversial. Here, we evaluated the association between preadolescent 100% fruit juice intake and later adolescent diet quality and body mass index (BMI). We used prospective data over 10 years from the National Growth and Health Study for 1921 black and white girls, ages 9–10 years at baseline, for analyses of diet quality, and 2165 girls for BMI analyses. Statistical analyses included repeated measures analysis of variance and logistic regression models. Girls who drank ≥1.0 cup/day of fruit juice in preadolescence consumed 0.44 cup/day more total fruit in later adolescence than non-juice-drinking girls (p &lt; 0.0001). White and black girls who drank ≥1.25 cups/day in preadolescence were 2.62 (95% CI: 1.35–5.08) and 2.54 (1.27–5.07) times more likely, respectively, to meet the Dietary Guidelines for whole fruit by later adolescence than those with the lowest juice intakes. Further, fruit juice consumption was positively associated with diet quality scores. Overall, girls consuming ≥1.25 cups/day of juice had a BMI in late adolescence that was 1.7 kg/m2 lower than that of non-juice-drinking girls. In conclusion, early adolescent fruit juice intake was positively associated with subsequent whole fruit consumption, better diet quality, and lower BMI in later adolescence.

Adherence to a priori dietary patterns in relation to obesity: results from two cycles of the Canadian National Nutrition Survey.

To test whether adherence to the Mediterranean diet, the Dietary Approaches to Stop Hypertension (DASH) or a dietary pattern in-line with the 2015-2020 Dietary Guidelines for Americans (DGA) was associated with obesity. 24-h dietary recall data from the Canadian Community Health Survey (CCHS)-Nutrition, 2004 and 2015 cycles, were analysed. Diet quality index scores were computed for the Mediterranean-Style Dietary Pattern Score (MSDPS), a DASH index and the 2015 Dietary Guidelines for Americans Adherence Index (DGAI). Higher scores indicated greater adherence. Association between scores and obesity was examined using logistic regression, adjusting for age, sex, physical activity, smoking status, sequence of dietary recall and alcohol and energy intake. Canada (excluding territories and the institutionalised population). Canadian adults (≥ 18 years), non-pregnant and non-breast-feeding; 11 748 from CCHS 2004 and 12 110 from CCHS 2015. The percentage of females in each sample was 50 %. Mean MSDPS, DASH and DGAI scores were marginally but significantly higher in CCHS 2015 than in CCHS 2004. Those affected by obesity obtained lower scores for all indexes in CCHS 2004 (OR 10th v. 90th percentile for DASH: 2·23 (95 % CI 1·50, 3·32), DGAI: 3·01 (95 % CI 1·98, 4·57), MSDPS: 2·02 (95 % CI 1·14, 3·58)). Similar results were observed in CCHS 2015; however, results for MSDPS were not significant (OR 10th v. 90th percentile for DASH: 2·45 (95 % CI 1·72, 3·49), DGAI: 2·73 (95 % CI 1·85, 4·03); MSDPS: 1·30 (95 % CI 0·82, 2·06)). Following DASH or the 2015-2020 DGA was associated with a lower likelihood of obesity. Findings do not indicate causation, as the data are cross-sectional.

Relationship between diet quality and biochemical profile in Brazilian overweight pregnant women

ObjectiveThe aim of this study was to evaluate the relationship between the Adapted Diet Quality Index for Pregnant Women (IQDAG) and the biochemical profile of overweight pregnant adult women. MethodsThis was a cross-sectional study, using baseline data from a randomized controlled clinical trial conducted with 239 pregnant women in Brazil. The usual diet was obtained through two dietary recalls and the Multiple Source Method. Diet quality was assessed using the IQDAG, which has nine components: eight for adequacy and one for moderation. Fasting blood glucose, insulin, total cholesterol, low-density lipoprotein, high-density lipoprotein, triacylglycerols, and C-reactive protein were measured to evaluate the biochemical profile. Adjusted linear regression models were used to evaluate the association between the score of the IQDAG (and its components) and the biochemical profile. The significance level considered was P ≤ 0.05. ResultsThe mean index score was 75.4 points. An inverse association was observed between the consumption of legumes and total cholesterol level (β = –4.76; 95% confidence interval [CI], –9.16 to –0.35; P = 0.03) and low-density lipoprotein (β = –4.13; 95% CI, –7.56 to –0.69; P = 0.02), and a direct association between calcium intake and total cholesterol (β = 0.02; 95% CI, 0.002–0.41; P = 0.03). No other associations were observed between the investigated variables. ConclusionsThe data from the present study suggest that higher consumption of legumes is associated with lower levels of total cholesterol and low-density lipoprotein. A higher intake of calcium was directly associated with total cholesterol . Further research is required to fully understand how diet quality affects pregnant women's biochemical profiles and what that means for the health of the mother and the fetus.

Quality of diet and odds of metabolic syndrome in Iranian adults: Baseline results from the PERSIAN Kavar cohort study (PKCS)

Background and aimsMetabolic Syndrome (MetS) is a major risk factor for cardiovascular diseases and type 2 diabetes mellitus. Diet quality has been associated with multiple chronic diseases. We aimed to investigate the association between the quality of diet and the odds of being diagnosed with MetS. Methods and resultsThis study was conducted cross-sectionally on baseline data of 2225 individuals from the PERSIAN Kavar Cohort Study (PKCS). The quality of diet was measured based on the Diet Quality Index – International (DQI-I), using Food Frequency Questionnaires. The association between DQI-I and MetS and its components was measured via logistic regression models in crude and adjusted models. We did not observe any association between DQI-I and MetS in the overall population. However, after adjustment for potential confounders, we found that male participants with higher DQI-I scores had a lower risk of MetS [adjusted odds ratio (OR) 95% confidence interval CI) = 0.62 (0.42–0.93)]. Moreover, analogous trends were observed with respect to some components of MetS, including elevated triglyceride (TG) [crude OR (95% CI) = 0.89 (0.70–0.98); adjusted OR = 0.82 (0.65–0.93)], lowered high-density lipoprotein cholesterol (HDL-c) [crude OR (95% CI) = 0.79 (0.57–0.99); adjusted OR = 0.76 (0.55–0.97)], and abnormal glucose homeostasis [crude OR (95% CI) = 0.80 (0.55–0.94); adjusted OR = 0.73 (0.51–0.91)] only in male participants, both before and after adjustment for potential confounders. ConclusionIn this study, we showed that higher adherence to a high-quality diet was associated with a lower chance of developing MetS in men.

Interactions of BDNF Val66met and dietary indices in relation to metabolic markers among patient with type 2 diabetes mellitus: a cross-sectional study

BackgroundGene–diet interaction is related to the progression of diabetes and cardiovascular diseases biomarkers. We aimed to evaluate the interaction between diet quality indices and BDNF Val66Mat (rs6265) on cardiometabolic markers among diabetic patients.MethodsThis cross-sectional study was conducted on 634 patients with type 2 diabetes mellitus, which were randomly recruited from diabetic centers in Tehran. Dietary intakes were estimated by a previously validated semi-quantitative food frequency questionnaire comprising 147 items. All participants were categorized into three categories, based on healthy eating index (HEI), diet quality index (DQI), and phytochemical index (PI) scores. Polymerase chain reaction was used for genotyping the BDNF Val66Met. Interactions were tested using analysis of covariance in adjusted and crude models.ResultsOur result showed that higher DQI, HEI, and PI scores significantly decrease body mass index and waist circumference among individuals with Met/Met, Val/Met, and Val/Val genotypes (P interactions < 0.05). Moreover, the highest quartile of the DQI and PI, compared to the lowest, showed lower TG level among Met allele carriers compared to Val/Val homozygotes (P interaction = 0.004 and 0.01, respectively) and a faster reduction in IL-18 and TC level was seen among Met/Met, Val/Met who had higher HEI intake than those with Val/Val genotype.ConclusionsBDNF Val66Met polymorphism may interact with HEI, DQI, and PI. We have revealed that Met allele acts as a protective allele for diabetic patients and may have a beneficial influence on cardio-metabolic factors through regulating dietary intake.

Adherence to the Mediterranean diet in Greek adolescents during COVID-19: exploring determining factors through cross-sectional study

PurposeDuring the pandemic, people have changed their diet and lifestyle, which are highly important to maintain health and well-being. This study aims to investigate the relationship between demographic, socioeconomic, dietary and lifestyle characteristics and adolescents' adherence to the Mediterranean diet (AMD).Design/methodology/approachIn all, 2088 youth from Attica, Greece, 12–18 years old, were recruited in this school-based, cross-sectional study conducted in May–December 2021. The tools Mediterranean Diet Quality Index for children and adolescents, the Family Affluence Scale III and the Godin-Shephard Leisure Time Physical Activity Questionnaire were used to estimate AMD, family affluence and the levels of physical activity (PA), respectively. Mann–Whitney U, Kruskal–Wallis, Chi-square tests, analysis of variance and multiple linear regression approaches were applied.FindingsEmpirical results showed that boys (p = 0.000), higher socioeconomic status (p = 0.034) and higher maternal education (p = 0.026) emerged as significant determinants for higher AMD. In addition, healthier dietary patterns (p = 0.000), PA (p = 0.000), more social lifestyle (p = 0.000) and night sleep duration (p = 0.000) were also positively correlated to diet quality. On the contrary, age (p = 0.000), screen time (p = 0.003) and the negative consequences of COVID-19 affected adversely AMD among adolescents.Originality/valueTo the best of the authors’ knowledge, this study was the first that highlighted the important role of several demographic, socioeconomic, dietary and lifestyle characteristics, together with the COVID-19 consequences to the AMD among secondary school children in Greece.

High Alternative Health Eating Index-Taiwan Scores Are Associated With Prevention of Graft Dysfunction in Taiwanese Renal Transplant Recipients

Various dietary quality indices demonstrate that a higher dietary quality score is associated with a reduced risk of several chronic diseases. However, creating an index tailored to the national population is crucial. The study investigated the association between the Alternative Healthy Eating Index-Taiwan (AHEI-Taiwan) and graft dysfunction in Taiwanese renal transplant recipients (RTRs). A prospective cohort study recruited 102 RTRs with a functioning allograft without acute rejection in the last 3 months from September 2016 to June 2018. Laboratory data were obtained from the medical records of patients. Graft dysfunction was indicated by an estimated glomerular filtration rate (eGFR) <60 mL/min per 1.73 m2 in accordance with the Kidney Disease Outcomes Quality Initiative guideline. The dietary quality index AHEI-Taiwan was adapted from the AHEI based on Taiwanese dietary recommendations. Mean age, renal transplant time, and eGFR were 48.9 ± 12.8 years, 8.5 ± 5.8 years, and 54.9 ± 17.8 mL/min per 1.73 m2, respectively, in 102 RTRs. The RTRs with the highest quartile of AHEI-Taiwan scores were older and had a higher eGFR. Logistic regression analysis adjusted for age, sex, calories, Charlson comorbidity index, transplant time, and dialysis time showed that the highest quartile of the AHEI-Taiwan was associated with an 88% (odds ratio, 0.12; 95% CI, 0.03-0.59, P < .01) lower risk of graft dysfunction. A high AHEI-Taiwan score was associated with a reduced risk of graft dysfunction in Taiwanese RTRs.
