Social Support, Health Behaviors, Self-Esteem, and Successful Aging in a Sub-Saharan African Sample of Older Adults: Test of a Sequential Mediation Model.

Background and Objectives: Previous research demonstrates that social support facilitates successful aging across all cultures. However, the factors that potentially mediate the link between social support and successful aging remain unclear. This study examined whether a healthy lifestyle and self-esteem mediate the association between social support and successful aging. It was hypothesized that the relationship between social support (family, friends, and significant other) and successful aging would be serially mediated by both healthy lifestyle and self-esteem. Research Design and Methods: Participants were 479 Nigerian retirees (53.4% female) aged 60 to 90 years (Mage = 64.81, SD = 6.86). They provided information on relevant demographic variables and completed the following measures: Fantastic Lifestyle Checklist (Fitness Appraisal), Rosenberg Self-esteem Scale, Multidimensional Scale of Perceived Social Support Scale, and Successful Aging Inventory. Three separate regression models (family, friends, and significant other dimensions of social support) were conducted using the Hayes PROCESS macro for SPSS with 5,000 bootstrap estimates. Results: Controlling for age and sex, family support, significant other support, friends support, healthy lifestyle, and self-esteem were directly associated with successful aging. The association between family support and successful aging was mediated by healthy lifestyle; and this was also seen for friends' support and significant other support. The sequential path from social support to successful aging through healthy lifestyle, and then via improved self-esteem, was significant for family support and significant other support, but not friends support. Discussion and Implications: Findings suggest that middle-aged to older adults who have strong support from their families and significant others may be more likely to engage in healthy behaviors and, in turn, experience higher levels of self-esteem, thereby aging well.

Working for the future: parentally deprived Nigerian Children have enhanced working memory ability.

BACKGROUND: The dominant view based on the deficit model of developmental psychopathology is that early adverse rearing impairs cognition. In contrast, an emerging evolutionary-developmental model argues that individuals exposed to early-life stress may have improved cognitive abilities that are adapted to harsh environments. We set out to test this hypothesis by examining cognitive functions in parentally deprived children in Nigeria. METHODS: Cognitive performance was compared between 53 deprived children who currently live in institutional homes and foster families and 51 nondeprived control participants. We used a multifaceted neurocognitive test battery for the assessment of inhibition, set-shifting and working memory. RESULTS: Results showed that the deprived and nondeprived group did not significantly differ in their performance on set-shifting and inhibition tasks. Conversely, the deprived group performed significantly better than the nondeprived group in the working memory task. DISCUSSION: We interpret the enhanced working memory ability of the deprived group as a correlate of its ecological relevance. In Nigeria, underprivileged children may need to rely to a larger extent on working memory abilities to attain success through academic work. This study provides further evidence that exposure to early adversity does not necessarily impair cognitive functions but can even enhance it under some conditions and in some domains.

Stressful life events, family support and successful ageing in the Biafran War generation.

OBJECTIVES: Although the developing countries contribute substantially to the population of the elderly, little is known about ageing in populous countries like Nigeria, particularly the Biafran War generation (BWG). Some of those who witnessed the Biafran War (also known as Nigerian Civil War) as children are well into late adulthood, while the majority of this pre-war/wartime cohort who are in their golden years will enter into later life in less than a decade from now. The aim of the present research was to examine the role of stressful life events and family support in successful ageing of the BWG. METHOD: Data were collected using a self-administered survey completed by 453 members of the BWG who were ≥45 years. The survey included measures such as the Successful Ageing Inventory, Life Events Inventory, and family support subscale of Family Dynamics Scale. Hierarchical multiple regression analyses were conducted to test the hypotheses of the study. RESULTS: The three dimensions of stressful life events (health events, interpersonal events and work-related/financial events) had moderate negative relationships with successful ageing. Family support was moderately and positively associated with successful ageing. For the moderation hypotheses, family support was a significant moderator of only the relationship between work-related stressful life events and successful ageing, especially for the <65 years subgroup. CONCLUSION: Growing old can be a very positive experience for both the individual and the society. Family support provides social protection for older people, in the face of difficult socio-economic circumstances.

Number of Dependents, Community Support, and Mental Health in Later Life: Does Gender Make a Difference?

This study examined associations of number of dependents and community support with mental health and whether the nature of these associations differs for males and females. Data were obtained from 209 elderly Nigerians using self-report measures. Hierarchical multiple regression (stepwise method) and Hayes regression-based PROCESS approach for tests of moderation were employed in analyzing the data. Results of a hierarchical multiple regression showed that number of dependents predicted mental health for the total sample and for men, but not for women. For the subgroups of men and women, there were significant predictions of mental health by community integration, community participation, and use of community organization, even after controlling for the roles of sociodemographic variables. The hypothesis on the moderation effect of community support on the associations of number of dependents and mental health was also supported. Findings highlighted the importance of addressing gender differences in the role of social capital in mental health.
