Grandparenting, Social Relations, and Mortality in Old Age.

ABSTRACT: Guided by a convoy model of social relations, this study investigates the relationships between grandparenting status, social relations, and mortality among community-dwelling grandparents age 65 and older who are caring for their grandchildren. The data were drawn from the 2008 and 2016 waves of the Health and Retirement Study (N = 564). Latent class analysis was used to identify the social network structure based on six indicators of interpersonal relationships and activities. A series of hierarchical Weibull hazard models estimated the associations between grandparent caregiving, social relations, and mortality risk. Results of survival analyses indicate that co-parenting and custodial grandparents had higher all-cause mortality risk than grandparents who babysat occasionally; however, for custodial grandparents, the association was not significant once social relation variables were added to the model. This study suggests that community-based support may be beneficial to older grandparents and improved relationship quality is integral to the well-being of older adults.

Project description:BackgroundSurvival to old ages is increasing in many African countries. While demographic tools for estimating mortality up to age 60 have improved greatly, mortality patterns above age 60 rely on models based on little or no demographic data. These estimates are important for social planning and demographic projections. We provide direct estimations of older-age mortality using survey data.MethodsSince 2005, nationally representative household surveys in ten sub-Saharan countries record counts of living and recently deceased household members: Burkina Faso, Côte d'Ivoire, Ethiopia, Namibia, Nigeria, Swaziland, Tanzania, Uganda, Zambia, and Zimbabwe. After accounting for age heaping using multiple imputation, we use this information to estimate probability of death in 5-year intervals ((5)q(x)). We then compare our (5)q(x) estimates to those provided by the World Health Organization (WHO) and the United Nations Population Division (UNPD) to estimate the differences in mortality estimates, especially among individuals older than 60 years old.FindingsWe obtained information on 505,827 individuals (18.4% over age 60, 1.64% deceased). WHO and UNPD mortality models match our estimates closely up to age 60 (mean difference in probability of death -1.1%). However, mortality probabilities above age 60 are lower using our estimations than either WHO or UNPD. The mean difference between our sample and the WHO is 5.9% (95% CI 3.8-7.9%) and between our sample is UNPD is 13.5% (95% CI 11.6-15.5%). Regardless of the comparator, the difference in mortality estimations rises monotonically above age 60.InterpretationMortality estimations above age 60 in ten African countries exhibit large variations depending on the method of estimation. The observed patterns suggest the possibility that survival in some African countries among adults older than age 60 is better than previously thought. Improving the quality and coverage of vital information in developing countries will become increasingly important with future reductions in mortality.

Project description:BackgroundThe epsilon2, epsilon3, and epsilon4 alleles of the apolipoprotein E gene (APOE) encode three isoforms, apoE2, E3, and E4, respectively. The apoE isoforms circulate in different plasma concentrations, but plasma concentrations of the same isoform also differ between individuals. Whereas the isoforms have been associated with cardiovascular disease, the relation between plasma apoE levels and cardiovascular disease is unknown.Methods and findingsWe assessed APOE genotypes, plasma levels of apoE, cardiovascular risk factors, and mortality in a population-based sample of 546 individuals aged 85 y who participated in the Leiden 85-plus Study and were prospectively followed for specific causes of death for 5 y. Participants in the highest tertile of apoE levels suffered a twofold-increased risk of cardiovascular mortality (hazard ratio compared to lowest tertile, 2.08; 95% confidence interval [CI], 1.30 to 3.33). Among the 324 participants with the epsilon3epsilon3 genotype, the hazard from cardiovascular disease was threefold increased (highest versus lowest tertile 3.01; 95% CI 1.60 to 5.66), with similar estimates for men and women. Other causes of death were not increased significantly. Plasma levels of apoE in epsilon3epsilon3 participants were positively correlated with total cholesterol (p < 0.001), low-density lipoprotein cholesterol (p < 0.001) and triglycerides (p < 0.001) and negatively with high-density lipoprotein cholesterol levels (p = 0.010). Adjustment for plasma lipids did not change the hazard ratios, whereas interaction was absent. The risk associated with high levels of apoE, however, was strongest in participants from the lowest tertile of C-reactive protein (CRP) levels and absent in those from the highest tertile (p(interaction) < 0.001). Among participants from the lowest tertile of CRP levels, those with a high apoE levels had a significantly steeper increase in CRP than those with low apoE levels (p = 0.020). Similar cardiovascular mortality risks as in epsilon3epsilon3 participants were found in epsilon2 and epsilon4 carriers.ConclusionsIn old age, high plasma apoE levels precede an increase of circulating CRP and strongly associates with cardiovascular mortality, independent of APOE genotype and plasma lipids.
