In this article, we examine birth cohort differences in parents’ provision of monetary help to adult children with particular focus on the extent to which cohort differences in family structure and the transition to adulthood influence these changes. Using data from the Health and Retirement Study from 1994 to 2010, we compare financial help to children of three respondent cohorts as the parents in these birth cohorts from ages 53–58 to 57–62. We find that transfers to children have increased among more recent cohorts. Two trends—declining family size and children’s delay in marriage—account for part of the increase across cohorts. However, other trends, such as the increase in the number of stepchildren and increasing child’s income level, tend to decrease the observed cohort trend.

Objectives: We examine the cumulative long-term role of childhood health and socioeconomic status in affecting functional health at ages 50 to 59. Method: Data on 2,233 respondents to The Irish Longitudinal Study of Aging (TILDA) are used to examine functional health measured by the timed-up-and-go (TUG) test of lower-body mobility. We examine the association of father’s education, childhood rural residence, and childhood self-evaluated health with TUG and examine respondent’s education, adult health behaviors, measured health, and cognition as mediators of the association of childhood characteristics and TUG. Results: Father’s education, rural residence, childhood health, and education are associated with TUG times at ages 50 to 59. While health behaviors mediate most of the rural residence and education associations, the association with childhood self-evaluated health is direct. Discussion: Early life circumstances play substantial direct and indirect roles in molding functional level in late mid-life.

Objective: This study investigates the relationship between intergenerational occupational mobility and objective physical functioning in later life. Method: Data come from The Irish Longitudinal Study of Ageing (TILDA), a nationally representative probability sample of 5,985 respondents aged 50 and older. Walking speed and grip strength are the functional health measures. The intergenerational occupational mobility measure characterizes origin and destination position as: professional/managerial, non-manual, skilled manual/semi-skilled, unskilled, never worked, and farmer. Results: Results indicated no direct association of childhood origin with walking speed or grip strength in later life, except for individuals from farming backgrounds. Those who experienced upward mobility were comparable in speed and strength with those who enjoyed high status (e.g., stable professional/managerial origin and destination) at both time points, whereas the downwardly mobile were comparable with those who were stable across generations at lower occupational positions. The results did not support the central tenets of the accumulation hypothesis. Respondents from farming backgrounds exhibited a clear performance advantage irrespective of destination, which, we speculate, may represent a critical period effect. Discussion: The mechanisms through which childhood origin affects health in later life are complex, but the position attained in adult life is most important. Intergenerational mobility is important only insofar as it leads to a destination occupation. The present findings suggest that the musculoskeletal system may accommodate environmental modification in adulthood.

Divorce and remarriage have reshaped the American family giving rise to questions about the place of stepchildren in remarried families. In this article, we examine money transfers from a couple to each of their children. We introduce characteristics of the family and estimate the role of shared family membership affecting all children in the family as well as the difference that stepchild status and other individual characteristics make in transfer flows. Data are from the Health and Retirement Study. There are two central results in the analysis. Overall, provision of financial help from parents to children is a family phenomenon. While help to a particular child is episodic, differences between families in provision of help were much greater than the differences in helping one child versus another within families. Second, stepchild status does differentiate one child from another within a family. Stepchildren are disadvantaged, particularly stepchildren of the wife.

Purpose of the Study: This article examines the impact of early- and later-life circumstances on loneliness among people aged 65+ in Ireland. Data are from the first wave of the Irish Longitudinal Study on Ageing, a nationally representative sample of community-dwelling adults aged 50+. The participants (N = 2,645) aged 65+ were included in the analysis. Because of the large number of never married persons in the older Irish population, we first used a multinomial logistic model to examine which childhood circumstances are associated with current marital status. We then estimated multiple regression models for loneliness, in stages conforming to the life course, to examine the extent to which early events are mediated by later events. Poor childhood socioeconomic status (for men and women) and parental substance abuse (for men) have direct effects on loneliness at older ages. The results indicate the significance of the childhood environment for understanding loneliness in later life. Future research should examine possible pathways not currently measured that may be responsible for the association of early environment and later-life loneliness and explore the links between childhood and other measures of well-being in old age. The relationship of childhood socioeconomic deprivation and parental substance abuse with adult well-being should be an important consideration in social policy planning.

Objective: This article contributes to the literature on depression and the life course by examining the impact of both early and later life circumstances on depressive symptoms among men and women aged 65 and over in Ireland. Method: Data are from the first wave of The Irish Longitudinal Study on Ageing, a nationally representative sample of 8504 community-dwelling adults aged 50 years and older. About 3507 respondents aged 65 years and over were included in the analysis. Multinomial logistic regression was used to examine the childhood and early adult life circumstances associated with marital status. A series of nested models were estimated to evaluate which childhood and adulthood circumstances are associated with depressive symptoms. Models were estimated separately for men and women. Results: Ill health in childhood and in later life has a strong and direct effect on depression in later life for both men and women. Other early stressors are mediated by later circumstances. Marital status is a significant independent predictor of depression in later life. Later life circumstances mediate between some marital statuses and depressive symptoms. When later life circumstances are included, widowhood and, for men, divorce, are directly associated with depression, but singlehood is not. Income in later life is strongly associated with depressive symptoms for women. Conclusion: Both early and later life circumstances affect late-life depressive symptoms. Our findings indicate that previous studies which did not consider both may have underestimated or overestimated the effect of marital status, education, current health and education on depressive symptoms.

This article examines the role of family structure in the financial support parents provide for their children's college education. Data are from the Health and Retirement Study. We focus on aspects of family structure that affect parental support and estimate shared family variance in investments as well as within-family variation using a multilevel model. Family membership accounts for about 60% of the variance in payment of college costs. Small family size, living with both biological parents (compared to one biological parent and a stepparent), higher parental education, and having older parents are associated with greater parental expenditures.

An adult child's provision of care to an unmarried elderly mother varies both within and between families. Within-family differences address the variation in different children's behavior within in a family. Between-family differences refer to the propensities that members of a family-the children of one mother-share and that differentiate them from other families. Previous research suggests five hypotheses affecting either within-family or between-family differences. Data from multiple waves of the Asset and Health Dynamics Among the Oldest Old (AHEAD) cohort of the Health and Retirement Study (HRS; 16,719 observations on 5,607 mother-child dyads in 1,925 families) are used to estimate a multilevel model with a binary outcome. Results indicate substantial differences between families. Mother's characteristics, family composition, and family history account for about half the between-family differences.

Objectives: This article examines the relationship between lifetime marital history and mortality after age 50. Method: Data are drawn from the Health and Retirement Study birth cohort of 1931 to 1941. The analysis utilizes three measures of marital history: number of marriages, proportion time married, and age at first marriage. Results: Three or more marriages and a lower proportion of adult life spent married are each associated with a higher hazard of dying after age 50 for both men and women even after controlling for current marital status and socioeconomic status. Smoking behavior accounts for part of the relationship of marital history and status with mortality. Discussion: Research on marital status and health should consider marital history as well as current status. Two topics are particularly important: examining the relationship in different cohorts and disentangling the potentially causal role of health behaviors such as smoking.

Examine the relationship between early age at first birth and mental health among women in their fifties. Analysis of data on women from a British 1946 birth cohort study and the U.S. Health and Retirement Study birth cohort of 1931-1941. In both samples a first birth before 21 years, compared to a later first birth, is associated with poorer mental health. The association between early first birth and poorer mental health persists in the British study even after controlling for early socioeconomic status, midlife socioeconomic status and midlife health. In the U.S. sample, the association becomes non-significant after controlling for educational attainment. Early age at first birth is associated with poorer mental health among women in their fifties in both studies, though the pattern of associations differs.
