Examining change in social support and fruit and vegetable consumption in African American adults

Associations Between Social Determinants of Health and Cardiovascular Health of U.S. Adult Cancer Survivors

Background

Relationships between the social determinants of health (SDOH) and cardiovascular health (CVH) of cancer survivors are underexplored.

Objectives

This study sought to investigate associations between the SDOH and CVH of adult cancer survivors.

Methods

Data from the U.S. National Health Interview Survey (2013-2017) were used. Participants reporting a history of cancer were included, excluding those with only nonmelanotic skin cancer, or with missing data for any domain of SDOH or CVH. SDOH was quantified with a 6-domain, 38-item score, consistent with the Centers for Disease Control and Prevention recommendations (higher score indicated worse deprivation). CVH was quantified based on the American Heart Association's Life's Essential 8, but due to unavailable detailed dietary data, a 7-item CVH score was used, with a higher score indicating worse CVH. Survey-specific multivariable Poisson regression was used to test associations between SDOH quartiles and CVH.

Results

Altogether, 8,254 subjects were analyzed, representing a population of 10,887,989 persons. Worse SDOH was associated with worse CVH (highest vs lowest quartile: risk ratio 1.30; 95% CI: 1.25-1.35; P < 0.001), with a grossly linear relationship between SDOH and CVH scores. Subgroup analysis found significantly stronger associations in younger participants (P interaction = 0.026) or women (P interaction = 0.001) but without significant interactions with race (P interaction = 0.051). Higher scores in all domains of SDOH were independently associated with worse CVH (all P < 0.001). Higher SDOH scores were also independently associated with each component of the CVH score (all P < 0.05 for highest SDOH quartile).

Conclusions

An unfavorable SDOH profile was independently associated with worse CVH among adult cancer survivors in the United States.

Religiosity and Physical Health of Middle–Old Aged African Americans: The Linking Role of Self-Control

Objective: This study examined a psychological process (i.e., sense of control) that links religiosity to self-reported physical health in older African Americans. Methods: Two waves of data from 231 middle–old aged African Americans (AAs) were used to test two specific hypotheses: (a) religiosity influences changes in sense of control middle–old aged AAs, and (b) sense of control influences changes in global physical health in middle–old aged AAs. The analysis used two modeling approaches: (a) an autoregressive cross-lagged modeland (b) a parallel growth/change model. Results: The results of both types of models showed that religiosity positively influenced changes in sense of control and that sense of control positively influenced changes in physical health in middle–old aged AAs over time. Discussion: These findings provide evidence that sense of control links religiosity to physical health in older African Americans. The theoretical and practical implications of the findings are discussed.

Social Isolation Is Associated With Rapid Kidney Function Decline and the Development of Chronic Kidney Diseases in Middle-Aged and Elderly Adults: Findings From the China Health and Retirement Longitudinal Study (CHARLS)

Background: There is limited evidence on the relationship between social isolation and renal outcomes. To address this gap, this study estimated the prospective relationship of social isolation with rapid kidney function decline and the development of chronic kidney disease (CKD) in middle-aged and elderly Chinese with normal kidney function. Methods: We analyzed data from 3,031 participants aged ≥ 45 years with baseline estimated glomerular filtration rates (eGFR) ≥ 60 ml/min/1.73 m². All data were obtained from the 2011 and 2015 waves of the Chinese Longitudinal Study of Health and Retirement (CHARLS). eGFR was estimated based on a combination of serum creatinine and cystatin C. The primary outcome was rapid decline in renal function, as defined by an eGFR decrease of > 5 ml/min/1.73 m² per year, while the secondary outcome was the development of CKD, as defined by an eGFR decrease to a level < 60 ml/min/1.73 m². Results: During the follow-up of 4 years, 258 (8.5%) participants experienced a rapid decline in renal function, while 87 (2.9%) developed CKD. In the fully adjusted model, high social isolation was significantly related to an increased risk of experiencing a rapid decline in renal function (OR 1.805, 95% CI 1.310-2.487) and CKD onset (OR 1.842, 95% CI 1.084-3.129). Among the five components of social isolation, being unmarried, not participating in social activities, and living alone independently predicted declined renal function. Conclusions: Social isolation is significantly associated with the risk of rapid eGFR decline and CKD onset in middle-aged and older adults with normal kidney function in China.

Perceptions of African American Adults With Type 2 Diabetes on Family Support: Type, Quality, and Recommendations

PURPOSE

The overall purpose of the study was to explore perceptions of family support in diabetes self-management among African American adults with type 2 diabetes.

METHODS

A qualitative study using focus group methodology and individual interviews was conducted. Thirty-seven African American adults with type 2 diabetes were recruited in the Midwest, United States. Data were analyzed using qualitative content analysis.

RESULTS

Themes emerged from the perspectives of the social interdependence theory. Positive family support included emotional support, instrumental support, and specific information or advice on diabetes management strategies. Positivity, family communication, and healthy eating/meal planning were perceived as helpful family behaviors. Negative support was perceived as intentional or unintentional behaviors. Family members' help in decision-making included goal setting with family member(s) and help in making decisions on diet and exercise. Recommendations included exercise and nutritional programs, support groups, family involvement, and materials and resources. Motivations for attending diabetes programs included involving family members, sharing success stories, seeing positive results, encouraging and caring, and providing incentives.

CONCLUSIONS

Intervention programs for African Americans should specifically target challenges in family support, healthy eating, and physical activity at an interpersonal level. Health care providers should assess family roles and family support to facilitate diabetes self-management for African Americans.

"I Struggle with Breast Cancer and I Struggle with God": Insights from African American Breast Cancer Survivors

PURPOSE

Recognizing that spiritual and religious beliefs are personal and vary within communities, the purpose of this qualitative study was to explore the influence of these beliefs on experiences with breast cancer care and social support among African American Christian breast cancer survivors.

METHODS

Forty-seven African American breast cancer survivors participated in focus groups (n = 7) in three northeastern urban cities. We used thematic analyses to identify major themes.

RESULTS

Three themes emerged relating to how spirituality influenced participants' cancer journeys: (1) struggling with God, (2) reclaiming my power, and (3) needing religious social support. Participants described the rhythmic flow of their spiritual beliefs as they navigated their lived experiences during diagnosis, treatment, and post-treatment. Spirituality was intimately intertwined with their illness experience as they grappled with their health and well-being.

CONCLUSIONS

Participants used spirituality as an avenue to cope and navigate through their diagnosis and treatment. These spiritual relationships created "church families" and provided the survivors' access to cancer support groups, financial support, and therapeutic support. Our findings support faith-based approaches to health promotion and call for more studies to understand the influence of religion on health.

BACKGROUND

There is limited evidence on the relationship between social support and renal outcomes in African Americans. We sought to determine the association of social support with prevalent chronic kidney disease (CKD) and kidney function decline in an African American cohort. We also examined whether age modifies the association between social support and kidney function decline.

METHODS

We identified Jackson Heart Study (JHS) participants with baseline (Exam in 2000-2004) functional and structural social support data via the Interpersonal Support Evaluation List (ISEL) and social network size questions, respectively. With ISEL as our primary exposure variable, we performed multivariable regression models to evaluate the association between social support and prevalent CKD [estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m2 or urine albumin-creatinine ratio (ACR) ≥30 mg/g], eGFR decline, and rapid renal function decline (RRFD) (> 30% decrease in eGFR over approximately 10 years). All models were adjusted for baseline sociodemographics, diabetes, hypertension, smoking status, and body mass index; models for eGFR decline and RRFD were additionally adjusted for eGFR and ACR. In models for eGFR decline, we assessed for interaction between age and social support. For secondary analyses, we replaced ISEL with its individual domains (appraisal, belonging, self-esteem, and tangible) and social network size in separate models as exposure variables.

RESULTS

Of 5301 JHS participants, 4015 (76%) completed the ISEL at baseline. 843 (21%) had low functional social support (ISEL score < 32). Participants with low (vs. higher) functional social support were more likely to have lower income (47% vs. 28%), be current or former tobacco users (39% vs. 30%), have diabetes (25% vs. 21%) or CKD (14% vs. 12%). After multivariable adjustment, neither ISEL or social network size were independently associated with prevalent CKD, eGFR decline, or RRFD. Of the ISEL domains, only higher self-esteem was associated with lower odds of prevalent CKD [OR 0.94 (95% CI 0.89-0.99)]. The associations between social support measures and eGFR decline were not modified by age.

CONCLUSIONS

In this African-American cohort, social support was not associated with prevalent CKD or kidney function decline. Further inquiry of self-esteem's role in CKD self-management and renal outcomes is warranted.
