Dietary Patterns and Their Association with Cardiometabolic Biomarkers and Outcomes among Hispanic Adults: A Cross-Sectional Study from the National Health and Nutrition Examination Survey (2013-2018).

Cardiovascular disease and metabolic disorders are disproportionately prevalent among Hispanic and Latino adults in the United States. We extracted a posteriori dietary patterns (DPs) among a nationally representative sample of 2049 Hispanic adults using the 2013-2018 National Health and Nutrition Examination Survey. Three primary DPs and their tertiles were identified, and their associations with cardiometabolic outcomes were examined. Those with higher levels of the Solids Fats, Cheeses, Refined Carbohydrates DP were more likely younger, male, and Mexican American. Those with higher levels of the Vegetables DP were more likely female, higher income, and long-term immigrant residents. Those with higher levels of The Plant-Based DP tended to have higher education levels. Higher levels of the Solid Fats, Cheeses, Refined Carbohydrates DP level were positively associated with body mass index (Tertile 2, ß: 1.07 [95%CI: 0.14, 1.99]) and negatively associated with lower high-density lipoprotein cholesterol (HDL-C) levels (Tertile 3, ß: -4.53 [95%CI: -7.03, -2.03]). Higher levels of adherence to the Vegetables DP were negatively associated with body fat (Tertile 3, ß: -1.57 [95%CI: -2.74, -0.39]) but also HDL-C (Tertile 2, ß: -2.62 [95%CI: -4.79, -0.47]). The Plant-Based DP showed no associations with cardiometabolic outcomes. Future research and interventions should consider these associations as well as the sociodemographic differences within each DP.

Randomized-controlled trial of a whole-family obesity prevention and treatment intervention designed for low-income Hispanic families: HeLP the healthy living program.

BACKGROUND: Low-income Hispanic families face marked disparities in obesity, but interventions for obesity prevention and treatment have rarely been designed with this population as a focus. Hispanic culture is characterized by Familism, a value that prioritizes familial respect, cooperation, and togetherness. We describe the rationale and design of a trial of the Healthy Living Program (HeLP), a bilingual whole-family behavioral obesity prevention and treatment intervention designed around the value Familism and addressing food insecurity. METHODS/DESIGN: This two-group randomized comparative effectiveness trial will compare the effects of HeLP versus a primary care counseling intervention (Recommended Treatment of Obesity in Primary Care, or RTOP) on decreasing body mass index (BMI; kg/m2) in Hispanic children 2-16 years of age with obesity and preventing BMI increase among siblings without obesity. 164 families per arm will be recruited from primary care practices. Families randomized to HeLP will participate in 12 two-hour sessions, followed by booster sessions. HeLP sessions include family meals and instruction in parenting skills, nutrition, culinary skills, fitness, and mindfulness delivered at community recreation centers by bilingual health educators and athletic trainers. Families randomized to RTOP will be offered individual visits in primary care every 3 months throughout the 18-month follow-up period. Secondary outcomes include changes to objectively measured child fitness, the home environment related to nutrition, physical activity, and media usage, food insecurity, child eating behaviors, quality of life, parent BMI and waist circumference, and implementation outcomes. DISCUSSION: This protocol paper describes the rationale and planned methods for the comparative effectiveness trial. TRIAL REGISTRATION: Clinicaltrials.gov Identifier NCT05041855 (6/13/2023).

Food Insecurity and Type 2 Diabetes Among Latinos: Examining Neighborhood Cohesion as a Protective Factor.

Qualitative work has found that Latino food pantry recipients share food and reciprocally provide social support to their food-insecure neighbors. These findings suggest that neighborhood cohesion (NC) may serve as an important community-level resource that Latinos utilize as a coping mechanism when food-insecure. High levels of NC may be a proxy for instrumental support outside the household and act as a buffer against the adverse health effects of food insecurity including type 2 diabetes (T2D), which is highly sensitive to food insecurity. The purpose of this study was to quantitatively test this theory by examining whether NC moderated the association between T2D and food security (FS) status among Latino adults nationwide. We used data from the 2013-2018 National Health Interview Survey (n = 23,478). We found that FS status was associated with T2D prevalence, with Latino adults having a higher odds of T2D if they had low FS or very low FS compared to their FS counterparts. We also found Latinos adults who reported high NC had a lower odds of T2D compared to those who reported low NC. However, we did not find there was significant interaction between FS status and NC on T2D. NC may instead be a precursor to FS status, rather than a buffer of food insecurity on T2D. Low NC may lead to less instrumental support and tangible benefits that determine FS. Additionally, perceived NC might not align with objective NC and T2D may be too distal of a health outcome to test the protective effect of NC.

Food insecurity, diabetes, and perceived diabetes self-management among Latinos in California: Differences by nativity and duration of residence.

We examined associations between food security (FS) status and type 2 diabetes (T2D) prevalence and perceived T2D self-management by nativity and US duration of residence among Latinos living in California. We used the California Health Interview Survey (2012-2017) and included Latinos who lived below 200% of the federal poverty line (n = 16,254) and for our management outcome, those with T2D (n = 2284). Latinos with low FS (OR = 1.44, 95% CI 1.14-1.83) or very low FS (OR = 1.87, 95% CI 1.33-2.61) had a higher odds of T2D compared to their food-secure counterparts. When stratified by nativity/duration in the US, US-born Latinos and Latino immigrants with >10 years duration had a higher odds of T2D if they reported low FS (US-born: OR = 1.60, 95% CI 1.02-2.52; >10 yrs: OR = 1.48, 95% CI 1.12-1.97) or very low FS (US-born: OR = 2.37, 95% CI 1.45-3.86; >10 yrs: OR = 1.78, 95% CI 1.15-2.76) compared to their food-secure counterparts. There was no association among immigrants with <10 years duration. For perceived T2D self-management, those with low or very low FS had lower odds of reporting proper management (OR = 0.56, 95% CI 0.36-0.86; OR = 0.46, 95% CI 0.26-0.83) compared to their food-secure counterparts. When stratified by nativity, the US-born did not differ in their perceived self-management by FS status, while immigrants with low or very FS had lower odds of perceived self-management (OR = 0.54, 95% CI 0.34-0.86; OR = 0.36, 95% CI 0.17-0.74), compared to their food-secure counterparts. Food insecurity may be an important contributor to T2D prevalence and perceived T2D self-management for Latino immigrants.

Exploring Dietary Factors in the Food Insecurity and Obesity Relationship Among Latinos in California.

We explored the role of dietary factors, as measured by individual behaviors and neighborhood produce availability, in the relationship between food insecurity and obesity among a representative sample of Latinos in California. We utilized data from the 2012, 2013/2014 California Health Interview Survey and included Latinos aged 18-65 years and under 200% of the federal poverty line (n=5,957). We conducted logistic regressions to first estimate the association between food insecurity and obesity and then examine whether this association remained significant after adjusting for soda and fast food consumption, perceived neighborhood fresh produce environment, and covariates. Latina women, and not men, were significantly more likely to be obese if they were very food insecure (OR=1.50, 95% CI=1.03-2.19). After adjusting for diet and neighborhood variables, only neighborhood affordability of fresh produce reduced this significant association. Policy efforts to remediate obesity among food insecurity households should focus on the affordability of neighborhood fresh produce.
