South Asians are among the fastest growing immigrant population groups in the United States. Their traditional diets are rich in minimally processed fruits, vegetables, grains, herbs, and spices. However, the proliferation of ultra-processed foods (highly processed, industrially manufactured formulations) around the globe may compromise the nutrition profile of South Asians, threatening to increase their risk of noncommunicable diseases. This commentary discusses the rise in ultra-processed food consumption among South Asians in the United States and hypothesizes that South Asians may be especially vulnerable to the effects of ultra-processed foods due to their unique cardiovascular disease risk profiles. Using these emerging data, we propose several strategies for preventing the overconsumption of ultra-processed foods among South Asian Americans. These include the implementation of policies to encourage the consumption of whole foods over ultra-processed foods and the development of culturally tailored interventions, which include promoting consumption of traditional diets, improving affordability of healthful, culturally appropriate foods, and cultivating healthier food environments for South Asians living in the United States.

High blood pressure is an important predictor of atherosclerotic cardiovascular disease (ASCVD), particularly among South Asians, who are at higher risk for ASCVD when compared to other population groups. The Dietary Approaches to Stop Hypertension (DASH) dietary pattern is established as the best proven nonpharmacological approach to preventing hypertension in adults. Using data from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) cohort, we calculated a DASH dietary score to examine the association between adherence to the DASH diet and its components, and prevalent and incident hypertension and systolic and diastolic blood pressure, after five years of follow-up. We found that the relative risk ratio (RRR) of incident hypertension was 67% lower among participants in the highest DASH diet score category (aRRR: 0.33; 95% CI: 0.13, 0.82; p_trend = 0.02) compared with those in the lowest DASH diet score category in fully adjusted models. These findings are consistent with previous clinical trials and large prospective cohort studies, adding to evidence that supports the diet-disease relationship established between DASH diet and hypertension. This study is the first to examine DASH diet adherence and hypertension among South Asian adults in the U.S.

OBJECTIVE:To examine diet quality and diet-related factors among male adults of reproductive age with and without disabilities. DESIGN/METHODS:Cross-sectional data from the National Health and Nutrition Examination Surveys, 2013-2018. SETTING/METHODS:Disability was reported as serious difficulty hearing, seeing, concentrating, walking, dressing and/or running errands due to physical, mental or emotional conditions. Diet quality was assessed by the Healthy Eating Index (HEI)-2015 and diet-related factors included self-rated diet healthfulness, food security and food assistance programmes. Multivariable linear regression estimated differences in HEI-2015 scores. Multivariable Poisson regression estimated adjusted prevalence ratios (aPR) and 95 % CI for diet-related factors. PARTICIPANTS/METHODS:In total, 3249 males, 18-44 years; of whom, 441 (13·4 %) reported having disabilities. RESULTS:Compared with males without disabilities, those with disabilities had a 2·69-point (95 % CI: -4·18, -1·20) lower mean total HEI-2015 score and approximately one-third to half of a point lower HEI-2015 component scores for greens and beans, total protein foods, seafood and plant proteins, fatty acids and added sugars. Males with any disabilities were more likely to have low food security (aPR = 1·57; 95 % CI: 1·28, 2·92); household participation in food assistance programmes (aPR = 1·61; 95 % CI: 1·34, 1·93) and consume fast food meals during the previous week (1-3 meals: aPR = 1·11; 95 % CI: 1·01-1·21 and 4 or more meals: aPR = 1·18; 95 % CI: 1·01-1·38) compared with males with no disabilities. CONCLUSIONS:Factors affecting diet and other modifiable health behaviours among male adults of reproductive age with disabilities require further investigation. Health promotion strategies that are adaptive to diverse populations within the disability community are needed.

PURPOSE OF REVIEW:Eating behaviors and dietary patterns begin in early childhood and persist into adolescence and adulthood, affecting lifelong acute and chronic disease risk. Vegetables provide a high density of necessary vitamins, minerals, and fiber. Dietary intake data show that children of all ages consume below the recommended range for vegetables. Pediatric providers are optimally positioned to promote vegetable intake in childhood. This review seeks to summarize lessons learned from behavioral interventions useful in the pediatric primary care setting to improve vegetable intake. RECENT FINDINGS:Ten published studies tested behavioral interventions in primary care to increase child vegetable intake. Strategies tested include teaching healthy eating behaviors and role modeling to parents of infants, and motivational interviewing paired with frequent office visits and reminders for families of older children and adolescents. Some strategies suggested positive change, despite study quality being limited by underpowered samples, heterogeneity of outcome measures, and statistical analytic approach. SUMMARY:Increased vegetable intake was achieved in infants through parental role-modeling when providers emphasized healthy dietary choices in parents. Older children increased their vegetable intake with motivational interviewing and frequent reminders from providers. Despite the high prevalence of inadequate vegetable intake among children, at present, there is only a modest body of literature to help guide pediatric providers in implementing practice-based interventions to improve vegetable intake in childhood, highlighting a need for high-quality research in this area.

BACKGROUND:Adult females of reproductive age (18-44 years) with disabilities have higher rates of health-risk behaviors and chronic conditions compared to their counterparts without disabilities; however, there is limited examination of diet. OBJECTIVE:To examine associations of self-reported disability status with diet quality and diet-related factors. DESIGN/METHODS:Cross-sectional data were from the National Health and Nutrition Examination Surveys, 2013-2018. PARTICIPANTS/SETTING/METHODS:Adult females aged 18-44 years were included. Disability was defined as serious difficulty hearing, seeing, concentrating, walking, dressing, and/or running errands due to physical, mental, or emotional conditions. MAIN OUTCOME MEASURES/METHODS:The Healthy Eating Index (HEI)-2015 assessed diet quality. Diet-related factors included self-rated diet healthfulness, meal characteristics, food security, and food assistance programs. STATISTICAL ANALYSIS/METHODS:Multivariable linear regression estimated differences in HEI-2015 scores for a given day and multivariable Poisson regression estimated adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) of diet-related factors by disability status. RESULTS:Of 3,579 adult females, 557 (16%) reported any disabilities, 207 (6%) of whom reported having two or more types of disabilities. Differences in mean HEI-2015 scores for a given day were one third to half of a point lower for fruits, total protein foods, and seafood/plant proteins among females with two or more types of disabilities compared to those without disabilities. Females with any disabilities were more likely to rate their diet as poor, have low food security, participate in food assistance programs, and consume frozen foods/pizza compared to those without disabilities (aPR ranged from 1.35 to 1.93); they were less likely to be the main food planner/preparer or shopper for their households. CONCLUSIONS:Some indicators of diet quality and diet-related factors differed between adult females with and without disabilities. Further investigation of dietary intakes and behaviors, as well as access to and availability of healthy foods, among females with disabilities is necessary.

Health status during the reproductive years influences fecundity, fertility, and the future health of males and their offspring. There remains a dearth of literature examining men's preconception health, especially among high-risk populations, such as those with disabilities. The objective of this study was to examine indicators of preconception health, including chronic medical conditions, lifestyle behaviors, and health care utilization, among males of reproductive age with and without disabilities in the United States. Data were from 3,702 males of reproductive age (18-44 years) who participated in the National Health and Nutrition Examination Surveys, 2013-2018. Approximately 14% of males reported having at least one disability related to vision, hearing, cognition, mobility, self-care, or independent living. Among all men, suboptimal preconception health indicators were prevalent including poor or fair self-rated health; low education and household income status; lack of health insurance and no recent utilization of health care and dental care; cigarette smoking; frequent alcohol consumption and binge drinking; marijuana and illegal drug use; obesity; low fruit and vegetable intake and no multi-vitamin use; low physical activity; short sleep durations; depressive symptoms; and hypertension and asthma. Compared to males with no disabilities, males with any disabilities were more likely to have suboptimal preconception health indicators. Strategies to promote and improve sexual health, preconception care, and family planning services among all men are needed. For males with disabilities, specifically, further investigation of their specific health needs related to sex, reproduction, family planning, and fatherhood, as well as interactions with health care providers, is required.

BACKGROUND:Woman's weight changes during pregnancy and postpartum contribute to obesity and health outcomes later in life. This study aimed to identify and characterize weight change trajectories from pregnancy to one year postpartum among adult women. METHODS:We used data from an ongoing cohort of healthy adult women (n = 819) with singleton pregnancies from 2007 - 2011. Sociodemographic data, pre-pregnancy body weight, and sedentary and breastfeeding practices were collected using questionaries applied by trained professionals. We applied a group-based trajectory modeling to distinguish weight change measured in the second and third trimesters of pregnancy and at one month, six, and 12 months postpartum. Multinomial regression models were run to characterize each trajectory. RESULTS:We identified six weight change trajectories with the main difference in the patterns followed after one month of delivery. One in three women (36.7%) was classified in some of the three postpartum weight gain trajectories and regained weight from the second trimester of the first year postpartum. Women who followed some of these trajectories were more likely to have higher age, obesity before pregnancy, < 10 years of schooling, and partner, compared with women (10.7%, n = 87) in a postpartum sustained-fast-lost-weight trajectory (p < 0.05). CONCLUSIONS:Women with obesity before pregnancy have higher odds of regaining gestational weight after delivery without reaching their pre-pregnancy weight. The first six months postpartum are crucial to establishing obesity prevention strategies. Further research is needed to evaluate the effect of the interventions that prevent substantial weight gain through reproductive years in high-risk women.

PURPOSE OF REVIEW/OBJECTIVE:Poor diet quality is the leading risk factor related to the overall cardiometabolic disease burden in the USA and globally. We review the current evidence linking ultra-processed foods and cardiometabolic health risk and provide recommendations for action at the clinical and public health levels. RECENT FINDINGS/RESULTS:A growing body of evidence conducted in a variety of study populations supports an association between ultra-processed food intake and increased risk of metabolic syndrome, hypertension, type 2 diabetes, overweight and obesity trajectories, and cardiovascular disease. The strongest evidence is observed in relation to weight gain and obesity among adults, as this association is supported by high-quality epidemiological and experimental evidence. Accumulating epidemiologic evidence and putative biological mechanisms link ultra-processed foods to cardiometabolic health outcomes. The high intake of ultra-processed foods in all population groups and its associated risks make ultra-processed foods an ideal target for intensive health promotion messaging and interventions.
