Russ TC, Kivimäki M, Batty GD. Respiratory Disease and Lower Pulmonary Function as Risk Factors for Dementia: A Systematic Review With Meta-analysis. Chest 2020; 157:1538-1558. [PMID: 31952950 DOI: 10.1016/j.chest.2019.12.012] [Citation(s) in RCA: 40] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 11/13/2019] [Accepted: 12/12/2019] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND In addition to affecting the oxygen supply to the brain, pulmonary function is a marker of multiple insults throughout life (including smoking, illness, and socioeconomic deprivation). In this meta-analysis of existing longitudinal studies, the hypothesis that lower pulmonary function and respiratory illness are linked to an elevated risk of dementia was tested. METHODS A systematic review was conducted of longitudinal studies using PubMed until April 1, 2019, and, where possible, results were pooled in random effects meta-analyses. RESULTS Ten studies relating pulmonary function to later dementia risk and 11 studies of respiratory illness and dementia (including one that assessed both factors) were identified. The lowest quartile of FEV1 compared with the highest was associated with a 1.4-fold (hazard ratio [HR], 1.46; 95% CI, 0.77-2.75) increased dementia risk (Ntotal = 62,209; two studies). A decrease of 1 SD in FEV1 was associated with a 28% increase in dementia risk (HR, 1.28; 95% CI, 1.03-1.60; Ntotal = 67,505; six studies). Respiratory illness was also associated with increased dementia risk to a similar degree (pooled HR, 1.54; 95% CI, 1.30-1.81; Ntotal = 288,641; 11 studies). CONCLUSIONS Individuals with poor pulmonary function experience an increased risk of dementia. The extent to which the association between poor pulmonary function and dementia is causal remains unclear and requires examination.

Abstract
Infertility is often recognised as a status that is medically identified in adulthood after unsuccessful attempts to conceive. This paper develops existing literature by illustrating how current conceptualisations of infertility do not incorporate a full range of experiences. Drawing on detailed, reflective diaries and in-depth interviews with five participants, I explore how infertility is experienced and understood by women with variations of sex characteristics (VSCs) or intersex traits. I argue that greater consideration needs to be applied to intersex people and the circumstances of an infertility status that may be received in infancy, childhood or adolescence, before or outside of attempts to conceive, and without undergoing fertility treatment. Through discussions of time and futurity, this paper seeks to explore how visions of the future coalesce with an infertile status that is received in combination with an atypical sex status early in life. The paper indicates that early infertility can hinder some intersex children and young people's ambitions. However, infertility is not understood to be pathological or consistently prohibitive throughout the lives of everyone affected. Intersex women's conceptions of a potentially childless future are varied, complex, ambivalent and, in some cases, transitional throughout the life course.

Abstract
The positive association between educational attainment and adult health ("the gradient") is stronger in some areas of the United States than in others. Explanations for the geographic pattern have not been rigorously investigated. Grounded in a contextual and life course perspective, this study assesses childhood circumstances (e.g., childhood health, compulsory schooling laws) and adult circumstances (e.g., wealth, lifestyles, economic policies) as potential explanations. Using data on US-born adults aged 50-59 at baseline (N=13,095) and followed for up to 16 years across the 1998-2014 waves of the Health and Retirement Study, this study examined how and why educational gradients in morbidity, functioning, and mortality vary across nine U.S. regions. The findings indicate that the gradient is stronger in some areas than others partly because of geographic differences in childhood socioeconomic conditions and health, but mostly because of geographic differences in adult circumstances such as wealth, lifestyles, and economic and tobacco policies.

Abstract
OBJECTIVE This article examines whether multidimensional indicators of objective and subjective socioeconomic status (SES) across the life course can be categorized into latent classes of SES mobility and tests the associations of these categories with inflammation markers among white and black adults. METHODS Data are from 592 non-Hispanic white and 158 non-Hispanic black participants who completed both the baseline survey and biomarkers assessment of the Midlife in the United States Refresher study. Groups of different SES mobility were examined using latent class analysis. RESULTS White and black participants showed different patterns of SES mobility. Among blacks, the latent classes were as follows: 1) objectively always high (24.71%; high objective SES across the life course), 2) subjectively always high (6.48%; high subjective and low objective SES across the life course), 3) downwardly mobile (35.84%; high childhood SES, low adult SES), and 4) always low (32.97%; low childhood SES, education, and adult SES). Among whites, the latent classes were as follows: 1) always high (52.17%; high childhood SES, high education, high adult SES), 2) upwardly mobile (18.14%; low childhood SES, high education, high adult SES), 3) subjectively downward (27.74%; high childhood SES, high education, high objective adult SES, low subjective adult SES), and 4) always low (1.95%; low childhood SES, education, and adult SES). SES mobility was associated with inflammation in white (Wald χ values (3) = 12.89-17.44, p values < .050), but not in black adults (Wald χ values (3) = 2.79-7.22, p values > .050). CONCLUSION The lack of SES mobility differentiation on inflammation is an indication of diminished return for the most affluent class among black participants.

Abstract
BACKGROUND Limited research has examined the association of life-course socioeconomic status (SES) with hypertension prevalence and incidence in a large cohort of African Americans. METHODS Among 4,761 participants from the Jackson Heart Study (JHS), we examined the association of SES indicators with prevalent and incident hypertension. We used multivariable Poisson regression to estimate prevalence ratios (PR, 95% confidence interval-CI) of baseline (2000-2004) hypertension by adult (education, income, occupation, wealth) and childhood (mother's education) SES. Cox proportional hazards regression was used to estimate hazard ratios (HR, 95% CI) of incident hypertension by adult and childhood SES (2005-2013; 7.21 median years of follow-up). We also examined the association of childhood-to-adult SES mobility (parent-to-adult education) with prevalent and incident hypertension. Model 1 adjusted for age and sex. Model 2 added waist circumference, behaviors (smoking, alcohol, physical activity, diet), and diabetes prevalence. RESULTS High (vs. low) adult SES measures were associated with a lower prevalence of hypertension, with the exception of having a college degree and upper-middle income (PR: 1.04, 95% CI: 1.01, 1.07; PR: 1.05, 95% CI: 1.01, 1.09, respectively). Higher childhood SES was associated with a lower prevalence and risk of hypertension (PR: 0.83, 95%: CI 0.75, 0.91; HR: 0.76, 95% CI: 0.65, 0.89, respectively). Upward mobility and consistent high SES (vs. consistent low SES) from childhood to adulthood was associated with a greater prevalence, but lower incidence of hypertension. CONCLUSION Efforts to prevent hypertension among African Americans should consider childhood and current SES status.

Abstract
A key uncertainty in the obesity-mortality association continues to be how this association changes over the life course. Prior studies tend to rely on cross-sectional design with static weight status taken at the time of the survey. This study tracks a cohort of individuals and employs lifelong body mass index information from the Framingham Heart Study original cohort (1948-2010). We focus on respondents who were younger than age 45 at time of their first survey (n = 2,176) and evaluate how the mortality risk associated with obesity changes over three age groups (below 45, 45-59, and 60 and above) and how population compositions may contribute to this pattern. We find the hazard ratio associated with obesity compared to normal weight decreases over three age groups, but this pattern is influenced by different ages of onset of obesity, inconsistency in the reference group (normal weight) over ages, and mortality selection effects. These factors explain away the decreasing effect of obesity (with onset before age 45) on mortality up to age 60; after age 60, the detrimental effect still declines, but to a much less degree. Later onset of obesity, however, is not significantly associated with excess mortality risks after age 60.

Abstract
It is unclear how coronary heart disease (CHD) risk across the adult life span affects late-life cognition. We estimated associations of midlife and late-life elevated CHD risk with cognitive trajectories (general cognitive performance, processing speed/executive function, memory) in later life (after age 55 years or age 70 years) among 2,892 Framingham Offspring Study participants who had completed CHD risk assessments approximately every 4 years since 1971 and had undergone neuropsychological testing between 1999 and 2014. We stratified analyses by apolipoprotein E gene (APOE) Ɛ4 allele carrier status. Using linear mixed-effects models, elevated CHD risk in midlife (age 55 years) was associated with lower levels of general cognitive performance (β = -0.560 standard deviation (SD) units, 95% confidence interval (CI): -0.874, -0.246), executive function (β = -0.624 SD units, 95% CI: -0.916, -0.332), and memory (β = -0.560 SD units, 95% CI: -0.907, -0.213) at age 70 years but not with rates of cognitive change. Late-life (age 70 years) elevated CHD risk, however, was associated with somewhat better levels of general cognitive performance and memory. There were associations between duration of elevated CHD risk during midlife and levels (but not trajectories) of later-life cognitive outcomes. Associations were not modified by APOE-ɛ4 status. These findings suggest that midlife elevated CHD risk is associated with lower cognition, independently of APOE-ɛ4 status, suggesting that risk of vascular disease may not contribute a "second hit" to AD risk.

Abstract
Work incapacity is a major public health challenge and an economic burden to both society and individuals. Understanding the underlying causes is becoming ever more relevant as many countries face an aging workforce. We examined stability and change in genetic and environmental factors influencing work incapacity from age 18 until retirement, and sex differences in these effects. The large population-based sample comprised information from 28,759 twins followed for up to 23 years combined with high-quality national registry data. We measured work incapacity as the total proportion of potential workdays lost due to sickness absence, rehabilitation and disability benefits. Structural equation modeling with twin data indicated moderate genetic influences on work incapacity throughout life in both men and women, with a high degree of genetic stability from young to old adulthood. Environmental influences were mainly age-specific. Our results indicate that largely the same genetic factors influence individual differences in work incapacity throughout young, middle and older adulthood, despite major differences in degree of work incapacity and probable underlying medical causes.

Abstract
This study investigates the importance of mid-career income for the gender pension gap and psychological scarring effects of low income earlier in life. More specifically we analyse whether women's typically less stable mid-life careers also affect outcomes in late careers and in retirement. Swedish income register data from 1990, 2009, and 2015 was linked to the "HEalth, Ageing, and Retirement Transitions in Sweden" survey. The gender pension gap of 966 retirees and worries about pension income of 2,723 older workers between the age of 60 and 66 years were investigated. Blinder-Oaxaca decompositions were applied to analyse the gender pension gap and linear regressions were used for the analysis of financial worries. Results show that gender differences in mid-career income play a stronger role for the gender pension gap than late career income. Mid-career income is furthermore related to higher worries about pension income and accounts for observed gender differences. Our findings demonstrate that gender gaps in mid-career income can be regarded as an open wound with visible negative effects in older ages. The reformed pension system in Sweden may potentially contribute to an even greater gender gap in pensions.

Abstract
A growing body of research suggests that maternal exposure to discrimination helps to explain racial disparities in children's health. However, no study has considered if the intergenerational health effects of unfair treatment operate in the opposite direction-from child to mother. To this end, we use data from mother-child pairs in the National Longitudinal Survey of Youth 1979 to determine whether adolescent and young adult children's experiences of discrimination influence their mother's health across midlife. We find that children who report more frequent instances of discrimination have mothers whose self-rated health declines more rapidly between ages 40 and 50 years. Furthermore, racial disparities in exposure to discrimination among children explains almost 10% of the black-white gap but little of the Hispanic-white gap in self-rated health among these mothers. We conclude that the negative health impacts of discrimination are likely to operate in a bidirectional fashion across key family relationships.

Abstract
BACKGROUND Subjective memory complaints (SMC) have been suggested as an early marker of mild cognitive impairment and dementia. However, there is a paucity of evidence on the effects of early life conditions on the development of SMC in old age. This study is aimed at investigating the association between childhood socioeconomic status (SES) and SMC in community-dwelling older adults. METHODS We used the data of the Japan Gerontological Evaluation Study, a population-based cohort study of people aged 65 years or older enrolled from 28 municipalities across Japan. Childhood SES and SMC in everyday life were assessed from the self-report questionnaire administered in 2010 (n = 16,184). Poisson regression was performed to determine their association, adjusted for potential confounders and life-course mediators and examined cohort effects. RESULTS We identified SMC in 47.4% of the participants. After adjusting for sex, age, and number of siblings, low and middle childhood SES were associated with 29% (prevalence ratio [PR]: 1.29, 95% confidence interval [CI]: 1.22, 1.36) and 10% higher prevalence of SMC (PR: 1.10, 95%CI: 1.04, 1.17), respectively, compared with high childhood SES (p for trend <.001). The interaction terms between childhood SES and age groups were not statistically significant. CONCLUSION Childhood SES is significantly associated with SMC among community-dwelling older adults. Efforts to minimize childhood poverty may diminish or delay the onset of SMC and dementia in later life.

Abstract
OBJECTIVE Telomere length is associated with poorer lung health in older adults, possibly from cumulative risk factor exposure, but data are lacking in pediatric and population-based cohorts. We examined associations of telomere length with lung function in children and mid-life adults. METHODS Data were drawn from a population-based cross-sectional study of 11 to 12 year-olds and mid-life adults. Lung function was assessed by spirometric FEV1 , FVC, FEV 1 /FVC ratio, and MMEF 25-75 . Telomere length was measured by quantitative polymerase chain reaction from blood and expressed as the amount of telomeric genomic DNA to the beta-globin gene (T/S ratio). Associations of telomere length with spirometric parameters were tested by linear and logistic regression models, adjusting for potential confounders of sex, age, body mass index, socioeconomic position, physical activity, inflammation, asthma, pubertal status, and smoking. RESULTS Mean T/S ratio was 1.09 (n = 1206; SD 0.55) in children and 0.81 (n = 1343; SD 0.38) in adults. In adults, for every additional unit in T/S ratio, FEV 1 /FVC and MMEF 25-75 z-scores were higher (β 0.21 [95% confidence interval, CI; 0.06-0.36] and 0.23 [95% CI; 0.08-0.38], respectively), and the likelihood of being in the lowest quartile for FEV 1 /FVC and MMEF 25-75 z-scores was lower (odds ratios 0.59 [95% CI, 0.39-0.89] and 0.64 [95% CI, 0.41-0.99], respectively). No evidence of association was seen for adult FEV 1 or FVC, or any childhood spirometric index after adjustments. CONCLUSION Shorter telomere length showed moderate associations with poorer airflow parameters, but not vital capacity (lung volume) in mid-life adults. However, there was no convincing evidence of associations in children.

Abstract
A growing body of research addresses the long-term implications of early-life circumstances for adult health and aging by drawing on retrospective reports on childhood. There has been little scholarly discourse on considerations for the design of such questions for members of racial/ethnic minority groups specifically. This article aims to encourage greater attention to this area by presenting insights from the process of designing a childhood history questionnaire within an ongoing study of cognition, health, and aging among older African American adults in greater Newark, New Jersey. The article presents on three overarching themes, including the importance of (a) adopting a resilience orientation with attention to protective factors, (b) being sensitive to concerns about questions on adverse childhood experiences, and (c) orienting to ethnoracially embedded cohort influences. The article concludes by describing the particular importance of cultural humility-with attention to intersectional social positions-among researchers who are engaged in studies on childhood with older adults from underrepresented racial/ethnic groups.

Abstract
Background This study examined the association between ideal cardiovascular health (CVH) and the retinal microvasculature in midadulthood. Methods and Results The Cardiovascular Risk in Young Finns Study included children from 5 Finnish University cities, who were chosen randomly from the national population register. Participants ranged from 12 to 18 years in childhood (1986) and from 37 to 43 years in midadulthood (2011). Ideal CVH was defined according to the American Heart Association criteria. Retinal microvascular measures included diameters, lengths, length:diameter ratio, and tortuosity. From childhood to adulthood, fasting plasma glucose and blood pressure were significantly higher in those with impaired fasting glucose or diabetes mellitus. Childhood ideal CVH was negatively associated with adult arteriolar tortuosity (β=−0.008; 95% confidence interval [CI], −0.01 to −0.003; P=0.001). Improved ideal CVH from childhood to adulthood was positively associated with adult arteriolar diameter (β=0.122; 95% CI, 0.01–0.24; P=0.033) and negatively associated with adult length:diameter ratio (β=−0.666; 95% CI, −1.25 to −0.08; P=0.026). When stratified by glucose metabolism, among those with diabetes mellitus and impaired fasting glucose, there was a negative association between childhood ideal CVH and adult venular diameter (diabetes mellitus: β=−2.75; 95% CI, −5.46 to −0.04; P=0.047; impaired fasting glucose: β=−2.13; 95% CI, −4.18 to −0.08; P=0.042). Conclusions This study is the first to comprehensively examine the impact of CVH from childhood to midadulthood on quantitative measures of the retinal microvasculature. Ideal CVH in childhood and improvement in CVH from childhood to adulthood appears to have a protective effect on the retinal microvasculature in those with, without, and at risk of diabetes mellitus.

Abstract
An international committee set up through the IAP for Health met to develop an action plan for dementia. Comprehensive international and national initiatives should move forward with calls for action that include increased public awareness regarding brain health and dementia, support for a broad range of dementia research objectives, and investment in national health care systems to ensure timely competent person-centred care for individuals with dementia. The elements of such action plans should include: 1) Development of national plans including assessment of relevant lifecourse risk and protective factors; 2) Increased investments in national research programs on dementia with approximately 1% of the national annual cost of the disease invested; 3) Allocating funds to support a broad range of biomedical, clinical, and health service and systems research; 4) Institution of risk reduction strategies; 5) Building the required trained workforce (health care workers, teachers, and others) to deal with the dementia crisis; 6) Ensuring that it is possible to live well with dementia; and 7) Ensuring that all have access to prevention programs, care, and supportive living environments.

Abstract
Background Women with hypertensive pregnancy disorders have adverse levels of cardiovascular risk factors. It is unclear how this adverse risk factor profile evolves during adult life. We compared life course trajectories of cardiovascular risk factors in women with preeclampsia or gestational hypertension in their first pregnancy to normotensive women. Methods and Results We linked information on cardiovascular risk factors from the population‐based HUNT (Nord‐Trøndelag Health Study) surveys with pregnancy information from the Medical Birth Registry of Norway. Trajectories of cardiovascular risk factors were constructed for 22 308 women with a normotensive first pregnancy; 1092 with preeclampsia, and 478 with gestational hypertension in first pregnancy. Already before first pregnancy, women with preeclampsia in their first pregnancy had higher measures of adiposity, blood pressure, heart rate, and serum lipids and glucose compared with women with a normotensive first pregnancy. After first pregnancy, there was a parallel development in cardiovascular risk factor levels, but women with a normotensive first pregnancy had a time lag of >10 years compared with the preeclampsia group. There were no clear differences in risk factor trajectories between women with gestational hypertension and women with preeclampsia. Conclusions Women with hypertensive pregnancy disorders in their first pregnancy had an adverse cardiovascular risk factor profile before pregnancy compared with normotensive women, and the differences persisted beyond 50 years of age. Hypertensive disorders in pregnancy signal long‐term increases in modifiable cardiovascular risk factors, and may be used to identify women who would benefit from early prevention strategies.

Abstract
Attitudes towards sexual health and relationships are learned from a young age, and there is an ongoing need for innovative and comprehensive approaches to sex education that keep pace with rapidly changing contexts of people's lives. We used thematic analysis of data from two qualitative studies in Scotland to explore learning contexts from a multi-generational perspective, as well as the influence of different socio-cultural factors on provision, access to and experience of sex education. The importance, but inadequacy, of school as a source of learning, was a persistent theme over time. Participants' strategies to address perceived gaps in knowledge included experience, conversations, vicarious and online learning. Gender and age differences emerged, with younger participants more likely to go online for information, and prevailing gender norms shaping attitudes and behaviours across both study groups. Participants who identified as gay, lesbian or bisexual described feeling particularly unprepared for sex and relationships due to the narrow, heteronormative content received. Although schools continue to be a common source of information, it appears that they fail to equip young people for their post-school sexual life-course. We recommend the mandatory provision of comprehensive, positive, inclusive and skills-based learning to improve people's chances of forming and building healthy, positive relationships across the lifespan.

Int J Geriatr Psychiatry 2019; 34:1642-1650. [PMID: 31328308 DOI: 10.1002/gps.5177] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Accepted: 07/17/2019] [Indexed: 11/10/2022]
Abstract
OBJECTIVES Lower socio-economic status (SES) may be associated with dementia later in life, but there is inconsistent evidence supporting this claim. We aim to examine the association between three SESs (education, job, and income indicators) and dementia onset in older adults. METHODS Study design was a 6-year prospective cohort study. Participants included a total of 52 063 community-dwelling adults aged 65 years or older without long-term care needs from the Japan Gerontological Evaluation Study. Outcome variable was dementia onset. Explanatory variables were educational years, the longest job held, and equivalised household income. We performed Cox proportional hazard analysis by gender with multiple imputation. RESULTS During the follow-up period, 10.5% of participants acquired dementia. The adjusted risks of dementia incidence of the participants with less than 6 years of education were 1.34 times (95% confidence interval [CI], 1.04-1.73) in men and 1.21 (1.00-1.45) times in women higher than those with more than 13 years of education. Females with less than 1.99 million yen (hazard ratio = 0.83, 0.72-0.96) of equivalised income were less likely to acquire dementia than those with four million yen or higher. CONCLUSIONS Educational attainment had a robust impact on dementia onset compared with the other SES factors in both genders of older Japanese people. Securing an education for children could be crucial to prevent dementia later in life. The longest job held was less likely to be risks of dementia incidence, compared with the other two factors.

Abstract
BACKGROUND Workers holding intermediate hierarchical positions in an institution may have a higher risk of occupational stress-related, ill health. This study examined the prevalence rates and odds ratios (ORs) of anxiety disorders among a hierarchical group of firefighters. METHODS This cross-sectional study samples firefighters from Minas Gerais, Brazil, who answered a structured questionnaire in 2011 (survey completion rate = 89.5%). The outcome of interest was a medical diagnosis of anxiety disorder. Bivariate and multivariate analyses were conducted among five hierarchical occupational positions: privates (lowest position), corporals, sergeants (intermediate position), sub lieutenants, and officers (highest position). RESULTS Overall, 8.4% of the sample reported an anxiety disorder, with the highest rate observed among intermediate workers (sergeants = 14.2%), followed by corporals (10%), privates (5.6%), sub lieutenants (5%), and officers (2.1%). Compared with privates, the unadjusted OR for sergeants was 2.49 (95% confidence interval, 1.35, 4.58). This finding remained statistically significant after adjustment for several control variables but was eliminated by age. CONCLUSION The mental health of firefighters is affected by social class position. Mental health promotion efforts should focus on longitudinal research and work toward interventions aimed at modifying the hierarchical structure of workplaces.

Abstract
BACKGROUND Shorter gestational age at birth is associated with worse academic performance in childhood. Socio-economic and demographic factors that affect a child's development may modify the relationship between gestational age and later academic performance. OBJECTIVE The purpose of this study was to investigate socio-economic and demographic effect modification of gestational age's association with kindergarten-level literacy skills in a longitudinal Wisconsin birth cohort. METHODS We sampled 153 145 singleton births (2007-2010) that linked to Phonological Awareness Literacy Screening-Kindergarten (PALS-K) scores (2012-2016 school years). PALS-K outcomes included meeting the screening benchmark (≥28 points, range 0-102 points) and the standardised score. Multivariable linear regressions of PALS-K outcomes on gestational age (completed weeks) included individual interactions for five maternal attributes measured at delivery: Medicaid coverage, education, age, race/ethnicity, and marital status. RESULTS Each additional completed gestational week was associated with a 0.5 percentage point increase in the probability of meeting the PALS-K literacy benchmark. The benefit of an additional week of gestational age was 0.5 percentage points (95% confidence interval 0.3, 0.7 percentage points) greater for Medicaid-covered births (0.8 percentage points) relative to non-Medicaid births (0.3 percentage points). Relative to only completing high school, having college education weakened this association by 0.3-0.6 percentage points, depending on years in college. Similar but modest relations emerged with standardised scores. CONCLUSIONS Socio-economic advantage as indicated by non-Medicaid coverage or higher levels of completed maternal education may diminish the cost of preterm birth on a child's kindergarten-level literacy skills.

Abstract
OBJECTIVES To study the change in body mass index (BMI) from childhood and adolescence and development of obesity into adulthood. STUDY DESIGN We performed a longitudinal study of 480 individuals (49% male; 67% white) with height and weight measures in childhood (mean age 7 years), repeated in adolescence (mean age 16 years) and adulthood (mean age 39 years). Weight status in childhood was defined as low normal weight (0-<50 BMI percentile); high normal weight (50-<85 BMI percentile); overweight (85-<95 BMI percentile); obese (≥95 BMI percentile). Adult weight status was defined as normal weight (18.5-<25 kg/m2); overweight (25-<30 kg/m2); obese (>30 kg/m2). RESULTS Adult obesity (%) increased with weight status in childhood (low normal weight 17%; high normal weight 40%; overweight 59%; obesity 85%) and similarly with adolescence. Children in a lower category in adolescence than in childhood had lower risk of having adult obesity than did those who maintained their childhood category. Among adults with obesity, 59% (111 out of 187) were normal weight as children, with 75% (83 out of 111) from the high normal weight children; and 50% of adults with obesity were normal weight (n = 94/187) as adolescents, with 84% (81 out of 94) from the high normal weight adolescents. Only 6% of 143 normal weight adults had either overweight (n = 9) or obesity (n = 0) during childhood. CONCLUSIONS This study shows the high risk for adult obesity in children and adolescents who have overweight or obesity. A majority of adults with obesity had a 50-85 BMI percentile as children. Those who did not move to higher weight status between childhood and adolescence had lower probability of adult obesity.

Abstract
Objectives: The paper identifies types of work-family trajectories of men and women and investigates their links with depression at older age. Method: We use data from the Heinz Nixdorf Recall study, with retrospective information on employment histories and parenthood between age 20 and 50 (1482 men and 1537 women, born between 1925 and 1955). We apply sequence analysis and group trajectories into six clusters for each gender. We test their association with two alternative measures of depression: self-reported depressive symptoms and intake of antidepressant medication. Multivariate models exclude participants with early life depression and adjust for age, marital status, education, and income. Results: We find clear differences of work-family trajectories between men and women, where women's trajectories are generally more diverse, and include family leaves and returns into full or part-time work. For men, work-family trajectories are neither related to depressive symptoms nor to medication intake. In contrast, women who returned into full-time work after family leave show more depression than those who return part-time, both in terms of depressive symptoms and intake of antidepressant medication. Conclusion: Our findings show gender differences in terms of work-family trajectories and their health-related consequences. In particular, findings suggest that mothers who return to full-time work are a vulnerable group for depression at older age and should be the focus of further research attention.

Abstract
Rural older women are surrounded by nature, a dynamic context for human development. Informed by place attachment and attention restoration theory, and guided by a life course perspective, this qualitative study focused on the perceived influence of nature in the lives of 34 rural older women. Using grounded theory techniques to analyze in-depth interviews, two primary findings emerged: (a) nature was integral to the women's identity; and (b) interactions with nature were motivated by prior positive spiritual and psychological outcomes. Findings revealed the power of the natural environment as a resource for coping with the challenges associated with aging.

Abstract
From birth, children living in disadvantaged socioeconomic circumstances (SECs) suffer from worse health than their more advantaged peers. The pathways through which SECs influence children's health are complex and inter-related, but in general are driven by differences in the distribution of power and resources that determine the economic, material and psychosocial conditions in which children grow up. A better understanding of why children from more disadvantaged backgrounds have worse health and how interventions work, for whom and in what contexts, will help to reduce these unfair differences. Macro-level change is also required, including the reduction of child poverty through improved social security systems and employment opportunities, and continued investment in high-quality and accessible services (eg, childcare, key workers, children's centres and healthy school environments). Child health professionals can play a crucial role by being mindful of the social determinants of health in their daily practice, and through advocating for more equitable and child-focussed resource allocation.

Abstract
Exposure to multiple forms of victimization has been shown to have increasingly negative outcomes, but their unique trajectory-setting effects have been largely unexplored. Using a life course approach, this article examines the life trajectories of child polyvictims. I use a nationwide sample including 3,652 respondents after cleaning and preparation. Seemingly unrelated regressions were used to predict depression and criminal behavior in childhood and adulthood. Results suggest that children who experience multiple forms of parental abuse tend to have life trajectories which grow increasingly worse through the life course. However, life trajectories of children experiencing violence outside the home have less persistent negative outcomes. Researchers and interventions should take differing life trajectories into account when attempting to aid different types of polyvictims.
