Stress associated with caregiving: an examination of the stress process model among Kenyan Luo elders.

Globally, a growing number of grandparents are caring for their grandchildren. The impact and burden associated with increases in custodial grandparenting, however, may differ by culture. In the United States, the caregiving role has been shown to be a significant source of stress for older adults. In cultures in which grandparents are more commonly involved in the care of young children, however, increasing caregiving roles may not be viewed as stressful. This study examines the impact of caregiving on perceived and physiological measures of stress among 640 Luo elders (60+) in western Kenya, where high HIV prevalence among younger-to-middle aged adults has led to a heavy burden of orphan care. Perceived stress levels were measured using the Luo Perceived Stress Scale (LPSS). Salivary cortisol and casual blood pressure were used as biomarkers of stress. Results were analyzed using random mixed effects models. Overall this study showed that caregivers have higher levels of perceived stress than non-caregivers. For women, household composition, including the number of orphans and adults in the homestead impacted perceived stress. Among men, those who perceived caregiving as burdensome had higher perceived stress. Despite the association between caregiving and perceived stress, there was a minimal relationship between caregiving and the two biomarkers of stress. This may be because caregiving is superimposed onto other stressors and therefore has a minimal physiological impact. These results highlight the importance of local context in determining the impact of the caregiving role on older adult well-being.

Caregiving, gender, and nutritional status in Nyanza Province, Kenya: grandmothers gain, grandfathers lose.

UNLABELLED: Based on anecdotal and qualitative reports, a general assumption is that caregiving negatively impacts grandparents in Africa. OBJECTIVES: The purpose of this article is to determine how caregiving and gender impact nutritional status over four waves of data from Luo elders. METHODS: Luo elders, aged 60 and over (age 73.6 ± 7.9) were sampled. Participant recruitment was rolling and included 287 Luo grandparents in 2005, 396 in 2006, 389 in 2007, and 390 in 2009. A total of 689 elders participated in at least 1 year. Standard anthropometric measures were used to determine nutritional status. Impact of caregiving was examined using structural equation models. RESULTS: Caregiving positively associated with nutritional status among women. This main effect was mediated by caregiving intensity, which also positively associated with nutritional status. Among men, caregiving negatively associated with nutritional status, although caregiving intensity did not significantly associate with most anthropometric measures. Socioeconomic status (SES) positively associated with five of nine anthropometric measures in women and all measures in men. Several measures indicated that both men and women became larger over time but few of the variables tested predicted growth. CONCLUSIONS: The beneficial impact on grandmothers might indicate a coping strategy. These results indicated that researchers should shift away from comparing caregivers to noncaregivers and instead look at the multiple factors which may make some families resilient and others at risk. Human biologists can contribute to this literature by examining the ecological and cultural contexts under which caregiving represents a burden with physiological repercussions.

Caregiving and cardiovascular disease risk factors in male and female Luo elders from Kenya.

BACKGROUND: The HIV/AIDS pandemic has created over 11 million orphans, who are primarily being cared for by grandparents. It has been suggested that this renewed parenting responsibility presents elders with added stressors. Few studies have systematically examined the impact of caregiving on health outcomes. AIM: The aim of this study was to examine the impact of caregiving on cardiovascular risk. It was hypothesized that caregiving would increase cardiovascular disease risk as measured by Framingham risk scores. SUBJECTS AND METHOD: 386 Luo elders (age = 73+/-8), divided into caregiving and non-caregiving groups, were recruited from the Nyanza Province, Kenya. Data were obtained from the participants including: Total cholesterol, HDL cholesterol, glucose, blood pressure, age, sex and smoking status. RESULTS: No significant difference was found between the Framingham risk scores of caregivers and non-caregivers. Among women increased BMI was positively associated with Framingham score (p=0.017), and among men increased waist circumference was positively associated with the score (p<0.001). Among women, the number of orphans under one's care lowered the risk of falling into the top quartile of the Framingham score while being a caregiver increased the risk of falling into the top quartile. CONCLUSION: This study demonstrates that there is not a simple relationship between caregiving and cardiovascular risk.
