Three features of early life course of Americans and Europeans during the twentieth century are of note: (1) the increased age-grading of transitions; (2) the closer spacing of different transitions, and (3) the more extensive overlap between economic and family transitions. Historical changes in the structure of individual life histories have been interpreted alternatively, as a consequence of industrialization and urbanization, or as the result of rising levels of the family and personal incomes available for consumption and investment in human capital skills. In this article we bring additional evidence to bear on this debate by comparing historical changes in the early life transitions of men and women in Japan and the United States. Trends in the transition to adulthood systematically relate to the structure of schools and labor markets in the two nations, drawing attention to the various life course implications of the institutional forms under which industrial societies may organize.

This chapter provides a synthesis of the literature on the transition to adulthood among emerging adults with a disability in the United States. The life course paradigm was used to frame the discussion in the context of demographic trends and contemporary circumstances regarding major life transitions in the areas of education, employment, independent living, and sex, marriage, and parenthood. A critical assessment of the current state of the literature from a social versus medical model of disability in these central life domains provides a foundation from which sociologists can explore processes of cumulative inequality embedded in the relatively uncharted lives of transition-age youth with a disability.

This review examines the role of schooling in the life course of individuals, focusing on the timing and sequencing of schooling in the transition to adulthood. First, I examine conceptual issues in the study of schooling and the life course, drawing heavily on the sociological literature. I then consider the timing and sequencing of schooling in the transition to adulthood in the United States, and the consequences of variations in the timing and sequencing of schooling for adult social and economic success. I then discuss the role of social structure, norms, and institutional arrangements in the transition to adulthood, with special attention to cross-national comparisons with the U. S. and historical changes within countries. I conclude with speculations regarding trends in the role of schooling in the life course, and some directions for future research on this topic.

Following Foote the life histories of twenty-seven white, middle-aged, middle class, American mothers were analyzed for career-like components [4]. Motherhood dominates the lives of these women but is only one of several careers which ebb and flow throughout their lives. Treating careers as developmental subdivisions in the life course, we understand how women can progress through life transitions and crises. Properties of careers, such as the emergent symbols of success, the clockwork which sets the time limits for career objectives, and the bargaining which these women undertake to work out career conflicts, all contribute to the understanding of how career is placed beside career to create each woman's career set. The career set acts as a social and personal resource, providing consistent and continuous meaning throughout major periods of time even in the face of major career stress or loss.

Folklore occurs at every stage of a person’s life, and this chapter covers the way folklore and folklife across, and of, the life course has been studied. Six divisions in the life course that mark traditions of age groups as well as perceived stages in the United States are pregnancy and birth, infancy and early childhood, childhood and adolescence, adulthood, seniority, and death. Although much of the scholarship of age groups has been on the beginning and end of life, I demonstrate the conditions of aging in adolescence through the senior years that generate folklore and should be studied in relation to formation of age-group identity. This chapter emphasizes the use of folklore as an adaptation to aging. It examines the connection of folk traditions to the role that anxiety plays in the aging process, the formation of self and group identity, and the rites of passage that mark transitions from one stage to another. It shows that the presence of invented and emerging traditions indicates changing values and beliefs across the life course and encourages research in age-based research as a basic component of folklore and folklife studies.

Abstract Racial health disparities in old age are well established, and new conceptualizations and methodologies continue to advance our understanding of health inequality across the life course. One group that is overlooked in many of these analyses, however, is the aging American Indian/Native Alaskan (AI/NA) population. While scholars have attended to the unique health inequities faced by the AI/NA population as a whole due to its discordant political history with the US government, little attention has been paid to unique patterns of disparity that might exist in old age. I propose to draw critical gerontology into the conversation in order to establish a framework through which we can uncover barriers to health, both from the political context of the AI/NA people as well as the political history of old age policy in the United States. Health disparities in old age are often described through a cumulative (dis)advantage framework that offers the benefit of appreciating that different groups enter old age with different resources and health statuses as a result of cumulative inequalities across the life course. Adding a framework of age relations, appreciating age as a system of inequality where people also gain or lose access to resources and status upon entering old age offers a path for understanding the intersection of race and old age. This paper will show how policy history for this group in particular as well as old age policy in the United States all create a unique and unequal circumstance for the aging AI/NA population.

Abstract Of all the various forms of adversity experienced during childhood, childhood maltreatment (emotional and physical abuse) is shown to have the largest impacts on mental health and well-being. Yet we still have a limited understanding of why some victims of early maltreatment suffer immense mental health consequences later on in the life course, while others are able to cushion the blow of these early insults. Using two waves of data from the National Survey of Midlife Development in the United States (MIDUS), this study considers change in religiosity as a buffer across three dimensions for victims of childhood abuse: religious importance, attendance, and the specific act of seeking comfort through religion. Results suggest that increases in religious comfort during adulthood are positively associated with adult mental health for victims of abuse, while decreases in religious comfort over time were associated with worse mental health. Changes in religious attendance and religious importance were not significant associated with mental health for victims of abuse. Taken together, my results show that the stress-moderating effects of religion for victims of childhood maltreatment are contingent on the stability or increases or decreases in religiosity over the life course, which has been overlooked in previous work.

Abstract Introduction: Racial disparities in cognitive function have been well-documented in the literature, but factors driving the disparities remain under explored. This study aims to quantify the extent to which cumulative stress exposures across the life course explain Black–White disparities in executive function and episodic memory. Method: Data were drawn from the 2004–2006 wave of the Midlife Development in the United States (MIDUS) and the MIDUS refresher study (N=5,967, 5,277 White, 690 Black). Cumulative stress exposures were assessed by using 10 domains of stressors (e.g., financial stress, childhood adversity). Cognitive function was assessed using the Brief Test of Adult Cognition by Telephone. Marginal structural models were conducted to quantify the proportion of the effect of race/ethnicity status on cognitive function that can be explained by cumulative stress exposures. Result: Blacks reported higher levels of cumulative stress exposures and lower average levels of executive function and episodic memory than Whites. Cumulative stress exposures explained 8.43% of the disparities in executive function and 13.21 % of the disparities in episodic memory. Cumulative stress exposures had stronger effects on racial disparities in cognitive function in the older age group (age≥ 55 years old) than in the younger age group (age < 55 years old). Conclusion: Cumulative stress exposures explain modest proportions of racial disparities in levels of cognitive function. Interventions that focus on reducing stress exposures or improving coping resources among Blacks may help lessen racial disparities in cognitive function at the population level.

Abstract Background Existing evidence suggests that there is an association between body size and prevalent Benign Prostatic Hyperplasia (BPH)-related outcomes and nocturia. However, there is limited evidence on the association between body size throughout the life-course and incident BPH-related outcomes. Methods Our study population consisted of men without histories of prostate cancer, BPH-related outcomes, or nocturia in the intervention arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) (n = 4710). Associations for body size in early- (age 20), mid- (age 50) and late-life (age ≥ 55, mean age 60.7 years) and weight change with incident BPH-related outcomes (including self-reported nocturia and physician diagnosis of BPH, digital rectal examination-estimated prostate volume ≥ 30 cc, and prostate-specific antigen [PSA] concentration > 1.4 ng/mL) were examined using Poisson regression with robust variance estimation. Results Men who were obese in late-life were 25% more likely to report nocturia (Relative Risk (RR): 1.25, 95% Confidence Interval (CI): 1.11–1.40; p-trendfor continuous BMI < 0.0001) and men who were either overweight or obese in late-life were more likely to report a prostate volume ≥ 30 cc (RRoverweight: 1.13, 95% CI 1.07–1.21; RRobese: 1.10, 95% CI 1.02–1.19; p-trendfor continuous BMI = 0.017) as compared to normal weight men. Obesity at ages 20 and 50 was similarly associated with both nocturia and prostate volume ≥ 30 cc. Considering trajectories of body size, men who were normal weight at age 20 and became overweight or obese by later-life had increased risks of nocturia (RRnormal to overweight: 1.09, 95% CI 0.98–1.22; RRnormal to obese: 1.28, 95% CI 1.10–1.47) and a prostate volume ≥ 30 cc (RRnormal to overweight: 1.12, 95% CI 1.05–1.20). Too few men were obese early in life to examine the independent effect of early-life body size. Later-life body size modified the association between physical activity and nocturia. Conclusions We found that later-life body size, independent of early-life body size, was associated with adverse BPH outcomes, suggesting that interventions to reduce body size even late in life can potentially reduce the burden of BPH-related outcomes and nocturia.

Introduction: Premature fatal cardiovascular disease rates have plateaued in the US. Identifying population distributions of short- and long-term predicted risk for atherosclerotic cardiovascular disease (ASCVD) can inform interventions and policy to improve cardiovascular health over the life course. Methods: Among nonpregnant participants age 30-59 years without prevalent CVD from the National Health and Nutrition Examination Surveys 2015-18, continuous 10 year (10Y) and 30 year (30Y) predicted ASCVD risk were assigned using the Pooled Cohort Equations and a 30-year competing risk model, respectively. Intermediate/high 10Y risk was defined as ≥7.5%, and high 30Y risk was chosen a priori as ≥20%, based on 2019 guideline levels for risk stratification. Participants were combined into low 10Y/low 30Y, low 10Y/high 30Y, and intermediate/high 10Y categories. We calculated and compared risk distributions overall and across race-sex, age, body mass index (BMI), and education using chi-square tests. Results: In 1495 NHANES participants age 30-59 years (representing 53,022,413 Americans), median 10Y risk was 2.3% and 30Y risk was 15.5%. Approximately 12% of individuals were already estimated to have intermediate/high 10Y risk. Of those at low 10Y risk, 30% had high 30Y predicted risk. Distributions differed significantly by sex, race, age, BMI, and education (P<0.01, Figure ). Black males more frequently had high 10Y risk compared with other race-sex groups. Older individuals, those with BMI ≥30 kg/m 2 , and with ≤high school education had a higher frequency of low 10Y/high 30Y risk. Conclusions: More than one-third of middle-aged U.S. adults have elevated short- or long-term predicted risk for ASCVD. While the majority of middle-aged US adults are at low 10Y risk, a large proportion among this subgroup are at high 30Y ASCVD risk, indicating a substantial need for enhanced clinical and population level prevention earlier in the life course.

Older adults are particularly prone to function-limiting health issues that adversely affect their well-being. Previous work has identified factors from across the life course –childhood socio-economic status, childhood cognitive ability and education – that predict later-life functional outcomes. However, the independence of these contributions is unclear as later-in-the-life-course predictors are themselves affected by earlier ones. The present study capitalised on the recent linkage of the Scottish Mental Survey 1947 with the Scottish Longitudinal Study, using path analyses to examine the direct and indirect associations between life-course predictors and the risk of functional limitation at ages 55 (N = 2,374), 65 (N = 1,971) and 75 (N = 1,534). The odds of reporting a function-limiting long-term condition increased across later life. At age 55, reporting a functional limitation was significantly less likely in those with higher childhood socio-economic status, higher childhood cognitive ability and higher educational attainment; these associations were only partly mediated by other predictors. At age 65, adult socio-economic status emerged as a mediator of several associations, although direct associations with childhood socio-economic status and childhood cognitive ability were still observed. At age 75, only childhood socio-economic status and adult socio-economic status directly predicted the risk of a functional limitation, particularly those associated with disease or illness. A consistent pattern and direction of associations was observed with self-rated health more generally. These results demonstrate that early-life and adult circumstances are associated with functional limitations later in life, but that these associations are partly a product of complex mediation between life-course factors.
