Adherence to a healthy diet and odds of metabolic syndrome: A cross-sectional study.

INTRODUCTION: Metabolic syndrome (MetS) is a major health concern around the world. Dietary factors, including diet quality, play a significant role in its pathophysiology. Healthy Eating Index (HEI) is a tool used as a valid measurement of the individual's diet quality. We aimed at investigating the relationship between diet quality as assessed by HEI-2015 and the risk of MetS and its components in a cross-sectional sample of suburban individuals from PERSIAN Kavar cohort study (PKCS), Fars province, Iran. METHODS: 2225 individuals meeting the eligibility criteria participated in the study. The relevant data were obtained from the baseline phase of PKCS. MetS was defined according to cut-offs presented by the National Cholesterol Education Program Adult Treatment Panel III (ATP III). HEI-2015 was calculated for the included individuals. Odds ratios were estimated. P-values <0.05 were considered as significant. RESULTS: The overall prevalence of MetS was 27.3%. Individuals with lower HEI-2015 scores had higher odds for MetS and its components. We observed that those who were categorized as the top HEI-2015 tertile had 42% (OR: 0.58; 95% CI: 0.38-0.90) lower odds of high blood pressure in the overall population. Also, the odds of high serum triacylglycerol was lower (OR: 0.72; 95% CI: 0.57-0.90) in those with the highest HEI-2015 scores. CONCLUSION: We found that higher dietary quality measured by HEI will decrease the risk of developing MetS, hypertension, and hypertriglyceridemia among Iranian adults. However, future interventional studies are required to further elucidate the issue.

Social Determinants of Rural Household Food Insecurity under the Taliban Regime.

Despite the severity of food insecurity in Afghanistan, little is known about the factors contributing to household food insecurity (HFI) under the Taliban regime. Therefore, this paper investigated the social determinants of severe HFI in rural areas of Afghanistan. We used the fifth-round survey of 6019 rural households from 25 provinces, collected between July and August 2022 by the Food and Agriculture Organization. We used binary logistic regression to examine the association between household characteristics and HFI. The majority of household heads were male (97.8%) with no education (62.8%). The findings showed that female-headed households had significantly higher odds of severe HFI. Household heads with any level of formal education had significantly reduced odds of severe HFI, while the odds of severe HFI was not different among those with religious/informal household-head education compared to those with no education. Likewise, engagement in any type of agricultural activity decreased the odds of severe HFI. Additionally, household income per member was negatively, while household size was positively associated with severe HFI. In summary, interventions to alleviate HFI among rural households should prioritize income-generating opportunities and skills targeting households with female heads, low levels of household-head education, larger size, no agricultural activities, and low income.

Association of plant-based dietary patterns with metabolic syndrome: baseline results from the Persian Kavar cohort study (PKCS).

Plant-based diets (PBDs) have gained a positive reputation among experts as a solution to combat the epidemic of MetS. A total of 2225 healthy Iranian individuals aged 35-70 years were considered eligible to be included in this cross-sectional investigation. Various dietary, anthropometric, and biochemical assessments were conducted using standard, valid methods/tools. Relevant PBD scores were calculated using three a posteriori indices, including the overall plant-based diet index (PDI), healthful PDI (hPDI), and unhealthful PDI (uPDI). Our findings showed that women with the highest adherence to hPDI had a lower chance of MetS. Also, participants in the top tertiles of hPDI were more likely to have a lower risk of low serum HDL-c and abnormal glucose homeostasis. Additionally, a significant increasing trend was observed for low serum HDL-c across tertiles of uPDI. Our observations suggest that healthful-rich plant foods may have a protective effect against MetS, especially in women.
