Chronic Stress and Unhealthy Dietary Behaviors among Low-Income African-American Female Caregivers.

ABSTRACT:

Background

Chronic stress increases the risk of excess intake of calorie-dense foods. Low-income minority caregivers in the United States are cumulatively exposed to stressors and unhealthy foods, but evidence of this association is limited in this population group. The objective of the current study was to assess the association between chronic stress and unhealthy dietary behaviors among low-income African-American caregivers in Detroit, Michigan.

Methods

Data came from Detroit Dental Health Project, a longitudinal study of pairs of African-American caregivers and children during 2002-2007. A sample of 912 female caregivers were included and their baseline (2002-2003) survey responses were analyzed to identify those with chronic stress and patterns of dietary behaviors. The likelihood of having unhealthy dietary behaviors was compared between chronically stressed caregivers and others, and the mediator role of depressive symptoms or current smoking was tested.

Results

Approximately 10% of caregivers experienced chronic stress as they all reported discrimination, residential movement, and lack of social support. Twenty-five percent of the caregivers were found to have an unhealthy dietary pattern characterized by excess intake of high fatty foods and soda. Chronically stressed caregivers were more likely to exhibit unhealthy dietary behaviors (prevalence ratio: 1.39; 95% CI: 1.05, 1.84), and this relation was significantly mediated by depressive symptoms, not current smoking.

Conclusions

These findings suggest that chronic stress played a role in negatively influencing dietary behaviors. As this association might be mediated by depressive symptoms, an intervention to reduce depressive symptoms can be considered as an effective strategy to promote healthy dietary behaviors among chronically stressed minority caregivers.

Project description:BackgroundCigarette smoking is a common risk factor for diseases and cancers. Oral microbiota is also associated with diseases and cancers. However, little is known about the impact of cigarette smoking on the oral microbiota, especially among ethnic minority populations.MethodsWe investigated cigarette smoking in relationship with the oral microbiota in a large population of predominately low-income and African-American participants. Mouth rinse samples were collected from 1616 participants within the Southern Community Cohort Study, including 592 current-smokers, 477 former-smokers and 547 never-smokers. Oral microbiota was profiled by 16S ribosomal RNA gene deep sequencing.ResultsCurrent-smokers showed a different overall microbial composition from former-smokers (p=6.62×10-7) and never-smokers (p=6.00×10-8). The two probiotic genera, Bifidobacterium and Lactobacillus, were enriched among current-smokers when compared with never-smokers, with Bonferroni-corrected p values (PBonferroni ) of 1.28×10-4 and 5.89×10-7, respectively. The phylum Actinobacteria was also enriched in current-smokers when compared with never-smokers, with a median relative abundance of 12.35% versus 9.36%, respectively, and with a PBonferroni =9.11×10-11. In contrast, the phylum Proteobacteria was depleted in current smokers (PBonferroni =5.57×10-13), with the relative abundance being almost three times that of never-smokers (7.22%) when compared with that of current-smokers (2.47%). Multiple taxa within these two phyla showed differences in abundance/prevalence between current-smokers and never-smokers at PBonferroni <0.05. The differences in the overall microbial composition and abundance/prevalence of most taxa were observed among both African-Americans and European-Americans. Meanwhile, such differences were not observed between former-smokers and never-smokers.ConclusionSmoking has strong impacts on oral microbial community, which was recovered after smoking cessation.

Project description:BackgroundPsychosocial factors are important determinants of health behaviors and diet-related outcomes, yet relatively little work has explored their relation to food-purchasing and preparation behaviors in low-income populations.AimTo evaluate the psychosocial factors associated with food-related behaviors.MethodsCross-sectional data collected from 465 low-income African American adult caregivers in the baseline evaluation of the B'more Healthy Communities for Kids obesity prevention trial. Questionnaires were used to assess household sociodemographic characteristics, food sources frequently used, and food preparation and food acquisition behaviors. Multiple linear regression models explored the associations between caregiver psychosocial variables and food-related behaviors, controlling for caregivers' age, sex, household income, household size, and food assistance participation.ResultsCaregivers purchased prepared food at carry-outs on average 3.8 times (standard deviation [ SD] = 4.6) within 30 days. Less healthy foods were acquired 2 times more frequently than healthier foods ( p < .001). Higher food-related behavioral intention and self-efficacy scores were positively associated with healthier food acquisition (β = 0.7; 95% confidence interval [CI] [0.09, 1.4]; β = 0.04; 95% CI [0.02, 0.06]) and negatively associated with frequency of purchasing at prepared food sources (β = -0.4; 95% CI [-0.6, -0.2]; β = -0.5; 95% CI [-0.7, -0.3]), respectively. Higher nutrition knowledge was associated with lower frequency of purchasing food at prepared food venues (β = -0.7; 95% CI: [-1.2, -0.2]).DiscussionOur findings indicate a positive association between psychosocial determinants and healthier food acquisition and food preparation behaviors.ConclusionInterventions that affect psychosocial factors (i.e., food-related behavioral intentions and self-efficacy) may have the potential to increase healthier food preparation and food-purchasing practices among low-income African American families.
