Family Environment and the Metabolic Syndrome: Results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study (SCAS)

Social Network Size and Severe Tooth Loss among Persons With Diabetes: Findings From the Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

Aims: The aims of this study were to examine the association of social network size with severe tooth loss and the number of missing teeth among Hispanic adults with diabetes in the United States and to assess whether the association varied by glycemic control. Methods: Data obtained from 1,007 adults who participated in the Hispanic Community Health Study were analyzed. Structural social support was measured with the Social Network Index (SNI), which assessed network size and frequency of social contacts. Tooth loss was measured by a count of the number of missing teeth and categorically as severe tooth loss (<9 remaining teeth). Descriptive statistical analyses were conducted to examine the sample characteristics. Logistic and negative binomial regression analyses were performed to examine the independent association between SNI and tooth loss and to test whether the association was modified by the glycemic target. Results: The prevalence of severe tooth loss was 5.91%. For each one-unit increase in SNI, the expected log count of the number of missing teeth was reduced by 3.3% (p-value: 0.037). Conclusions: In this study, a larger social network size was associated with fewer missing teeth among Hispanic persons living with diabetes. Further examination of social support and oral health is warranted.

Current Family Functioning and Youth Cardiometabolic Health in the SOL Youth Study

BACKGROUND

Family functioning may impact children's cardiometabolic health; however, few studies have examined multiple cardiometabolic markers among a diverse racial/ethnic cohort. The relationship between child- and caregiver-reported family functioning and the cardiometabolic health of Hispanic/Latino youth was examined.

METHOD

Data were from the Hispanic Community Children's Health Study/Study of Latino Youth (SOL Youth) (2012-2014), a population-based cohort study of children and adolescents whose parents participated in the HCHS/SOL (2008-2011). The relationship between youth- and caregiver-rated family functioning, and concordance of ratings is modeled, utilizing the general functioning subscale of the McMaster Family Assessment Device with youth objective cardiometabolic health markers (obesity, central adiposity, prediabetes/diabetes, prehypertension/hypertension, triglycerides, HDL cholesterol) adjusting for sociodemographic factors.

RESULTS

Among boys, child/caregiver concordant ineffective family functioning rating was associated with higher cumulative cardiometabolic risk (adjusted B (95% CI): 0.30 (0.04, 0.56)), but no association was observed among girls (adjusted B (95% CI): 0.04 (-0.13, 0.21)). Among girls, ineffective child rating/effective caregiver rating was associated with higher cumulative cardiometabolic risk (adjusted B (95% CI): 0.27 (0.06, 0.48)), but no association was observed among boys (adjusted B (95% CI): 0.02 (-0.23, 0.27).

CONCLUSION

Findings suggest that family functioning among this Hispanic/Latino population may influence cardiometabolic risk among youth. Observed differences in the associations by youth sex and concordant/discordant reports of family functioning suggest interventions at the family level, targeting both caregivers and youth, that consider differential sex effects are warranted.

Evolving Science on Cardiovascular Disease Among Hispanic/Latino Adults: JACC International

The landmark, multicenter HCHS/SOL (Hispanic Community Health Study/Study of Latinos) is the largest, most comprehensive, longitudinal community-based cohort study to date of diverse Hispanic/Latino persons in the United States. The HCHS/SOL aimed to address the dearth of comprehensive data on risk factors for cardiovascular disease (CVD) and other chronic diseases in this population and has expanded considerably in scope since its inception. This paper describes the aims/objectives and data collection of the HCHS/SOL and its ancillary studies to date and highlights the critical and sizable contributions made by the study to understanding the prevalence of and changes in CVD risk/protective factors and the burden of CVD and related chronic conditions among adults of diverse Hispanic/Latino backgrounds. The continued follow-up of this cohort will allow in-depth investigations on cardiovascular and pulmonary outcomes in this population, and data from the ongoing ancillary studies will facilitate generation of new hypotheses and study questions.

Influence of Stress, Gender, and Minority Status on Cardiovascular Disease Risk in the Hispanic/Latino Community: Protocol for a Longitudinal Observational Cohort Study

BACKGROUND

Hispanic/Latino sexual and gender minorities (SGM) are the fastest growing ethnic group of SGM in the United States. Cardiovascular disease (CVD) is a leading cause of morbidity and mortality among Hispanics/Latinos. SGM inequities in CVD risk have been identified as early as young adulthood, and minority stress has been identified as a potential mediator. Yet, the small number of ethnic or racial minority participants in SGM studies have precluded the examination of the intersections of sexual orientation, gender identity, and race and ethnicity.

OBJECTIVE

Minority stress models conceptualize relationships between stressors in minority groups and health outcomes. In this study, we will (1) examine the influence of sexual orientation and gender identity on CVD risk among all Hispanic Community Health Study/Study of Latinos (HCHS/SOL) participants at visit 3 (2021-2024; N~9300); (2) model pathways from sexual orientation and gender identity to CVD risk through stigma, discrimination, and stress in a 1:2 matched subcohort of SGM and non-SGM participants at visit 3 (n~1680); and (3) examine the influence of resilience factors on sexual orientation or gender identity and CVD risk relationships among subcohort participants at visit 3 (n~1680).

METHODS

This study will leverage existing data from the parent HCHS/SOL study (collected since 2008) while collecting new data on sexual orientation, gender identity, stigma, discrimination, stress, coping, social support, and CVD risk. Data analysis will follow the SGM minority stress model, which states that excess stigma against SGM populations leads to minority stress that increases CVD risk. In this model, coping and social support serve as resilience factors that can mitigate the impact of minority stress on CVD risk. Cross-sectional and longitudinal regression models as well as structural equation models will be used to test these relationships.

RESULTS

This study was funded by the National Heart, Lung, and Blood Institute in March 2020. Recruitment is scheduled to begin in the first quarter of 2021 and continue through 2024.

CONCLUSIONS

Understanding the influence of stigma-induced stress on CVD risk among Hispanic/Latino SGM has significant implications for the development of culturally specific CVD risk reduction strategies. Study findings will be used to build on identified Hispanic/Latino cultural strengths to inform adaptation and testing of family and community acceptance interventions.

Moving Diabetes Upstream: the Social Determinants of Diabetes Management and Control Among Immigrants in the US

PURPOSE OF REVIEW

Relative to the US-born population, immigrants are less likely to successfully manage and control their diabetes, leading to a host of diabetes-related complications. This review draws on the social determinants of health framework (SDoH) to summarize the multilevel factors that shape diabetes care and management among immigrants in the USA.

RECENT FINDINGS

While the diabetes literature is replete with research on individual-level risk factors and health behaviors, empirical literature linking the SDoH to diabetes management among immigrants is limited. However, housing precarity, food insecurity, poverty, uninsurance and underinsurance, and limited support for immigrants in healthcare systems are consistently shown to deter diabetes management and care. Immigrants with diabetes face a multitude of structural constraints to managing their diabetes. More research that theorizes the role of SDoH in diabetes management along with empirical qualitative and quantitative studies are needed. Interventions to address diabetes also require a more upstream approach in order to mitigate the drivers of diabetes disparities among immigrants.

Family Support and Family Negativity as Mediators of the Relation between Acculturation and Postpartum Weight in Low-Income Mexican-Origin Women

BACKGROUND

Obesity presents a significant health concern among low-income, ethnic minority women of childbearing age.

PURPOSE

The study investigated the influence of maternal acculturation, family negativity, and family support on postpartum weight loss among low-income Mexican-origin women.

METHODS

Low-income Mexican-origin women (N=322; 14% born in the U.S.) were recruited from a prenatal clinic in an urban area of the Southwest U.S. Acculturation was assessed during a prenatal home visit (26-38 weeks gestation), and post-birth family support and general family negativity were assessed at 6 weeks postpartum. Objective maternal weight measures were obtained at five time points across the first postpartum year.

RESULTS

Higher acculturation predicted higher family support and family negativity. Higher family support predicted decreasing weight across the first postpartum year, and higher family negativity predicted higher weight at 6 weeks postpartum and increasing weight across the first postpartum year. In combination, family negativity and support mediated the impact of acculturation on postpartum weight gain.

CONCLUSIONS

Cultural and family-related factors play a significant role in postpartum weight gain and loss for low-income Mexican-origin women.

Relationships of family conflict, cohesion, and chaos in the home environment on maternal and child food-related behaviours

This study examined how food-related behaviours differed in mothers and their preschool children by levels of family functioning (cohesion and conflict) and household disorganization (chaos). A nationally representative sample of mothers of preschoolers completed an online survey assessing food-related behaviours of themselves and their children. Maternal and child diet, eating behaviours, and health status; household availability of fruits/vegetables, salty/fatty snacks, and sugar-sweetened beverages; family mealtime atmosphere; and family conflict, cohesion, and household chaos were assessed with valid, reliable scales. Cluster analyses assigned families into low, middle, and high conflict, cohesion, and chaos groups. Participants (n = 550) were 72% White, and 82% had some post-secondary education. Regression analysis examining the association of cluster grouping levels on diet-related behaviour measures revealed that positive home environments (i.e., low family conflict, high family cohesion, and low household chaos) were associated with healthier food-related behaviours (e.g., increased fruits/vegetables intake), whereas negative home environments (i.e., high family conflict, low family cohesion, and high household chaos) were associated with unhealthy food-related behaviours (e.g., greater % total calories from fat) even after controlling for sociodemographic and related behavioural factors. Findings suggest family functioning and household chaos are associated with food-related behaviours. This frequently overlooked component of family interaction may affect intervention outcomes and objectives of educational and interventional initiatives.
