Book Description
A unique observational long-term study In a long follow-up period of 23 years about 600 teenagers were observed till their young adult age in order to investigate the longitudinal relationship between health and lifestyles considering physical activity, diet, smoking and alcohol consumption. Longitudinal studies with a follow-up lasting for a quarter of a century are very rare and the Amsterdam Growth and Health Longitudinal Study (AGAHLS) is indeed unique among them. The focus is multidisciplinary and involves both physical and psychological determinants in relation to a wide range of health outcomes. The multiple measurements were carefully standardized in nine waves of data collection, thus producing a high-quality data set, which has been analyzed by the application of advanced statistical techniques. The monograph provides not only an overview of 23 years of follow-up, it also summarizes over 200 scientific publications and 10 PhD theses. This publication is especially recommended to investigators planning longitudinal research, to health workers, and to authorities who like to implement health promotional activities in their community.

Book Description
Growth, Maturation and Body Composition documents one of the most remarkable and significant studies in the field of human biology. The Fels Longitudinal Study is the longest, largest and most productive serial study of human growth, maturation and body composition. This book shows how data collected from more than 1000 participants during the past 60 years have been analysed to test a wide range of hypotheses, and describes how the findings have led to the development of improved research methods. Topics covered include the management and analysis of data, prenatal, familial and genetic studies, physical growth, development and maturation, bones and teeth, body composition, and risk factors for cardiovascular disease. With more than 1000 specialized publications of Fels data, the present book provides a unique overview of this fascinating research programme, which will be of interest to a wide range of researchers, including those in the fields of physical anthropology, nutrition science, pediatrics, gerontology, epidemiology, endocrinology, human genetics, as well as statistics.

Book Description
Longitudinal principal components analyses on a combination of four subcutaneous skinfolds (biceps, triceps, subscapular and suprailiac) were performed using data from the London Longitudinal Growth Study. The main objectives were to discover at what age during growth sex differences in body fat distribution occur and to see if there is continuity in body fatness and body fat distribution from childhood into the adult status (18 years). The analyses were done for four age sectors (3mon-3yrs, 3yrs-8yrs, 8yrs-18yrs and 3yrs-18yrs). Longitudinal principal component one (LPC1) for each age interval in both sexes represents the population mean fat curve. Component two (LPC2) is a velocity of fatness component. Component three (LPC3) in the 3mon-3yrs age sector represents infant fat wave in both sexes. In the next two age sectors component three in males represents peaks and shifts in fat growth (change in velocity), while in females it represents body fat distribution. Component four (LPC4) in the same two age sectors is a reversal in the sexes of the patterns seen for component three, i.e., in males it is body fat distribution and in females velocity shifts. Components five and above represent more complicated patterns of change (multiple increases and decreases across the age interval). In both sexes there is strong tracking in fatness from middle childhood to adolescence. In males only there is also a low to moderate tracking of infant fat with middle to late childhood fat. These data are strongly supported in the literature. Several factors are known to predict adult fatness among the most important being previous levels of fatness (at earlier ages) and the age at rebound. In addition we found that the velocity of fat change in middle childhood was highly predictive of later fatness (r $\approx -$0.7), even more so than age at rebound (r $\approx -$0.5). In contrast to fatness (LPC1), body fat distribution (LPC3-LPC4) did not track well even though significant components of body fat distribution occur at each age. Tracking of body fat distribution was higher in females than males. Sex differences in body fat distribution are non existent. Some sex differences are evident with the peripheral-to-central ratios after age 14 years.

Book Description
This open access book examines health trajectories and health transitions at different stages of the life course, including childhood, adulthood and later life. It provides findings that assess the role of biological and social transitions on health status over time. The essays examine a wide range of health issues, including the consequences of military service on body mass index, childhood obesity and cardiovascular health, socio-economic inequalities in preventive health care use, depression and anxiety during the child rearing period, health trajectories and transitions in people with cystic fibrosis and oral health over the life course. The book addresses theoretical, empirical and methodological issues as well as examines different national contexts, which help to identify factors of vulnerability and potential resources that support resilience available for specific groups and/or populations. Health reflects the ability of individuals to adapt to their social environment. This book analyzes health as a dynamic experience. It examines how different aspects of individual health unfold over time as a result of aging but also in relation to changing socioeconomic conditions. It also offers readers potential insights into public policies that affect the health status of a population.

Book Description
The period of adolescence is a transitional developmental stage, critical in shaping health trajectories across the life course. While many individuals traverse the adolescent transition relatively unscathed, a number suffer from significant health problems from adolescence to adulthood. Recent studies have begun to investigate the biological mechanism through which social conditions early in the life course influence health trajectories. Previous research on allostatic load, an indicator of physiological dysregulation resulting from the wear and tear of stress, has focused on adults and the aging, but few have explored allostatic load among adolescents. Additionally, recent literature has begun to explore the mechanisms through which social conditions during adolescence lead to changing obesity patterns during the transition to adulthood, though none have considered the mediating mechanism of stressful life events. Using data from two nationally representative samples of adolescents age 12 to 19 years, the National Health and Nutrition Examination Survey (NHANES) (N = 8,431) and the National Longitudinal Study of Adolescent Health (Add Health) (N = 9,311), the overarching goals of this study were (1) to investigate sociodemographic correlates of AL across adolescence from age 12 to 19 years, and (2) to determine whether stressful life events (SLE) in adolescence explain the relationship between adolescent sociodemographic factors and longitudinal patterns of obesity from adolescence to young adulthood. The research for this dissertation drew upon life course, social stratification, and stress process theories. Specific significant differences in AL among adolescents by age and race/ethnicity were found. In particular, higher AL scores, suggestive of greater cumulative physiological dysregulation, were significantly associated with older age and Black race/ethnicity. Select significant mediating pathways of adolescent SLE on becoming obese among males were also found. Mediation analysis revealed that SLE done to adolescent males partially explained the relationship between age and low family income on becoming obese over time. Surprisingly, no significant mediating effects of adolescent SLE on longitudinal obesity patterns were found among females. This study provided the first examination of associations between major sociodemographic factors and AL among a nationally representative sample of adolescents. The concept of AL offers great promise toward expanding our understanding of how social and environmental factors are embodied within our biological regulatory systems, and translated into disease outcomes and health disparities. The present research has significant implications for informing health prevention interventions among younger populations. Additionally, by focusing on the intervening mechanism through which adolescent social conditions may affect obesity, this research contributes to an understanding of the processes of obesity development during childhood and adolescence. These findings point to possible interventions that can prevent obesity among young males who are from low SES households. Recommendations regarding stress management and coping mechanisms could aid in the fight against the increasing obesity epidemic among the younger population.
