Objectives To estimate the relationship between patient characteristics and referral decisions made by musculoskeletal hubs, and to assess the possible impact of an evidence-based referral tool. Design Retrospective analysis of medical records and decision tree model evaluating policy changes using local and national data. Setting One musculoskel...

Aims: To assess how the cost-effectiveness of total hip arthroplasty (THA) and total knee arthroplasty (TKA) varies with age, sex, and preoperative Oxford Hip or Knee Score (OHS/OKS); and to identify the patient groups for whom THA/TKA is cost-effective. Methods: We conducted a cost-effectiveness analysis using a Markov model from a United Kingd...

Retirement is a major life event potentially associated with changes in relevant risk factors for cardiovascular and metabolic conditions. This study analyzes the effect of retirement on behavioral and biomedical risk factors for chronic disease, together with subjective health parameters using Southern German epidemiological data. We used panel da...

Retired parents might invest time in their adult children by providing childcare. Such intergenerational time transfers can have important implications for family decisions. This paper estimates the effects of parental retirement on the fertility of their adult children. We use representative panel data from Germany to link observations on parents...

Incentivizing restraint in drug use The accelerating tide of antimicrobial resistance (AMR) is a major worldwide policy concern. Like climate change, the incentives for individual decision-makers do not take into account the costs to society at large. AMR represents an impending “tragedy of the commons,” and there is an immediate need for collectiv...

We study how population variation in testosterone levels impacts male labour market earnings using data from the UK Household Longitudinal Study between 2011 and 2013. We exploit genetic variation between individuals as instrumental variables following a Mendelian Randomization approach to address the endogeneity of testosterone levels. Our finding...

This paper examines the causal effect of childcare provision on grandparents’ health in the United States. We use the sex ratio among older adults’ children as an instrument for grandparental childcare provision. Our instrument exploits that parents of daughters transition to grandparenthood earlier and invest more in their grandchildren than paren...

Public parental leave schemes aim to facilitate women’s reconciliation of family and employment after their transition into motherhood. While parental leave policies underwent several reforms over the past decades, adapting to changing female labour market participation and family cultures, the available entitlements are not tailored to women’s ind...

To check claims of a “loneliness epidemic,” we examined whether current cohorts of older adults report higher levels and/or steeper age-related increases in loneliness than earlier-born peers. Specifically, we used 1,068 age-matched longitudinal reports (Mage observations = 79 years, 49% women) of loneliness provided by independent samples recruite...

The poor live paycheck to paycheck and are repeatedly exposed to strong cyclical income fluctuations. We investigate whether such income fluctuations affect their risk preference. If risk preference temporarily changes around payday, optimal decisions made before payday may no longer be optimal afterward, which could reinforce poverty. By exploitin...

Existing literature shows the importance of maternity leave as a strategy for women to balance work and family responsibilities. However, only a few studies focused on the long-run impact of maternity leave length on maternal health. Therefore, how exactly they are related remains unclear. We examine women’s selection into different lengths of mate...

History-graded increases in older adults’ levels of cognitive performance are well documented, but little is known about historical shifts in within-person change: cognitive decline and onset of decline. We combined harmonized perceptual-motor speed data from independent samples recruited in 1990 and 2010 to age-match 2,008 longitudinal observation...

We examine whether retirement has a causal effect on the frequency of voluntary work provision in Europe and the U.S. We draw on data from the English Longitudinal Study of Ageing, The Irish Longitudinal Study on Ageing, the Survey of Health, Ageing and Retirement in Europe and the Health Retirement Study for the period 2009-2017 and use eligibilit...

We conduct a genome-wide association study (GWAS) of educational attainment (EA) in a sample of ~3 million individuals and identify 3,952 approximately uncorrelated genome-wide-significant single-nucleotide polymorphisms (SNPs). A genome-wide polygenic predictor, or polygenic index (PGI), explains 12–16% of EA variance and contributes to risk predi...

Biological processes have provided new insights into diverging labour market trajectories. This paper uses population variation in testosterone levels to explain transition probabilities into and out of unemployment. We examine labour market transitions for 2,004 initially employed and 111 initially unemployed British men from the UK Household Long...

This study uses prospective data spanning 27 years (1991-2018) to explore the relationship between economic precariousness and young Britons' transition to a first coresidential partnership according to age, historical time and gender over historical time. Economic precariousness is measured using several objective and subjective indicators, such a...

An extensive body of research shows that motherhood has substantial impacts on women's earnings, but there is less evidence on the effect of the timing of motherhood, particularly in the long term and from contexts other than the US. This study analyses data from the 1970 British Cohort Study (BCS70) to examine whether the timing of motherhood affe...

A large body of empirical evidence has accumulated showing that the experience of old age is "younger," more "agentic," and "happier" than ever before. However, it is not yet known whether historical improvements in well-being, control beliefs, cognitive functioning, and other outcomes generalize to individuals' views on their own aging process. To...

The relationship between urbanization, the brain, and human mental health is subject to intensive debate in the current scientific literature. Particularly, since mood and anxiety disorders as well as schizophrenia are known to be more frequent in urban compared to rural regions. Here, we investigated the association between cerebral signatures, me...

This paper examines the causal impact of retirement on preventive care use by focusing on breast cancer screening. It contributes to a better understanding of the puzzling results in the literature reporting mixed effects on health care consumption at retirement. We use five waves of data from the Eurobarometer surveys conducted between 1996 and 20...

Introduction: Control beliefs can protect against age-related declines in functioning. It is unclear whether neighborhood characteristics shape how much control people perceive over their life. This article studies associations of neighborhood characteristics with control beliefs of residents of a diverse metropolitan area (Berlin, Germany). Meth...

This study tests whether being in an exogamous union affects older individual's family networks, and whether associations between exogamy and mental health reported in previous studies operate through changes in family ties and differ by gender. We focus on individuals aged 60 or above in the German Socio‐Economic Panel Study between 2002 and 2016....

Many public health interventions aim to provide individuals with health information on the consequences of behaviours such as smoking, alcohol consumption or preventive care use, with the intention of changing health behaviour through better health knowledge. This paper examines whether the provision of health information in organised breast cancer...

Biological processes have provided new insights into diverging labour market trajectories. In this paper, we use population variation in testosterone levels to explain transition probabilities into and out of unemployment. We follow individual employment histories for 1,771 initially employed and 109 initially unemployed British men from the UK Hou...

Population ageing is expected to increase the burden of non-communicable diseases, e.g., cardiovascular diseases and cancer. These diseases are amenable to prevention, such as lifestyle changes (primary prevention) and early detection (secondary prevention), and thus prevention is considered to be one of the keys to maintaining the health of an age...

Voluntary work is an important contribution for many non-profit organizations, such as charities, political and religious organizations. Older individuals make up a sizable share of the volunteer workforce, and volunteering is often regarded as an example of "active ageing". In this study, we examine whether retirement has a causal effect on the fr...

Objectives: This study tests whether being in an exogamous union, in which one of the partners is an immigrant and the other native, affects an older individual's social networks, and whether the association between exogamy and mental health operates through social networks. We hypothesize that immigrants gain social capital through their native sp...

Life Span theory posits that sociohistorical contexts shape individual development. In line with this proposition, cohort differences favoring later-born cohorts have been widely documented for cognition and health. However, little is known about historical change in how key resources of psychosocial functioning such as control beliefs develop in o...

Background There is no good evidence to support the use of patient-reported outcome measures (PROMs) in setting preoperative thresholds for referral for hip and knee replacement surgery. Despite this, the practice is widespread in the NHS. Objectives/research questions Can clinical outcome tools be used to set thresholds for hip or knee replacemen...

Research on close relationships in later life has received increased attention over the past decade. However, little is known about sexuality and intimacy in old age. Using cross-sectional data from the Berlin Aging Study II (BASE-II; Mage = 68 years, SD = 3.68; 50% women; N = 1,514), we examine age differences in behavioral (sexual activity), cogn...

Humans vary substantially in their willingness to take risks. In a combined sample of over one million individuals, we conducted genome-wide association studies (GWAS) of general risk tolerance, adventurousness, and risky behaviors in the driving, drinking, smoking, and sexual domains. We identified 611 approximately independent genetic loci associ...

Breast cancer is one of the major causes of death among women aged 50 and above. Early detection considerably improves survival, and therefore many countries have introduced breast cancer screening programs. This paper examines the causal impact of retirement on the uptake of mammography screening. We use data from a series of Eurobarometer surveys...

Objectives To assess how costs and quality of life (measured by EuroQoL-5 Dimensions (EQ-5D)) before and after total hip replacement (THR) and total knee replacement (TKR) vary with age, gender and preoperative Oxford hip score (OHS) and Oxford knee score (OKS). Design Regression analyses using prospectively collected data from clinical trials, co...

Background The last decades have seen great advances in the understanding, treatment, and prevention of cardiovascular disease (CVD). Although mortality rates due to CVD have declined significantly in the last decades, the burden of CVD is still high, particularly in older adults. This raises the question whether contemporary populations of older a...

Enriched environments elicit brain plasticity in animals. In humans it is unclear which environment is enriching. Living in a city has been associated with increased amygdala activity in a stress paradigm, and being brought up in a city with increased pregenual anterior cingulate cortex (pACC) activity. We set out to identify geographical character...

Introduction: Medication therapy for type 2 diabetes has become increasingly complex, and there are few reliable data on the current state of clinical practice. We report treatment pathways and associated costs of medication therapy for people with type 2 diabetes in the UK, their variability and changes over time. Methods: Prescription and biom...

The genetic architecture of human reproductive behavior—age at first birth (AFB) and number of children ever born (NEB)—has a strong relationship with fitness, human development, infertility and risk of neuropsychiatric disorders. However, very few genetic loci have been identified, and the underlying mechanisms of AFB and NEB are poorly understood...

We examine how late-life personality development relates to overall morbidity as well as specific performance-based indicators of physical and cognitive functioning in 1,232 older adults in the Berlin Aging Study II (aged 65-88 years). Latent growth models indicated that, on average, neuroticism and conscientiousness decline over time, whereas extr...

Educational attainment is strongly influenced by social and other environmental factors, but genetic factors are estimated to account for at least 20% of the variation across individuals1. Here we report the results of a genome-wide association study (GWAS) for educational attainment that extends our earlier discovery sample1, 2 of 101,069 individu...

Very few genetic variants have been associated with depression and neuroticism, likely because of limitations on sample size in previous studies. Subjective well-being, a phenotype that is genetically correlated with both of these traits, has not yet been studied with genome-wide data. We conducted genome-wide association studies of three phenotype...

Background: Neighborhood characteristics are important determinants of individual health and well-being. For example, characteristics such as noise and pollution affect health directly, while other characteristics affect health and well-being by either providing resources (e.g. social capital in the neighborhood), which individuals can use to cope...

Background: Lifespan psychological and life course sociological perspectives indicate that individual development is shaped by social and historical circumstances. Increases in fluid cognitive performance over the last century are well documented and researchers have begun examining historical trends in personality and subjective well-being in old...

Background: Excessive loss of muscle mass in advanced age is a major risk factor for decreased physical ability and falls. Physical activity and exercise training are typically recommended to maintain muscle mass and prevent weakness. How exercise in different stages of life relates to muscle mass, grip strength, and risk for weakness in later lif...

This paper investigates the mechanisms behind the health effects of retirement. Using a Regression Discontinuity Design to exploit financial incentives in the German pension system for identification, I find that retirement improves subjective health status and mental health, while also reducing outpatient care utilization. I explore a wide range o...

How sociocultural contexts shape individual functioning is of prime interest for psychological inquiry. Secular increases favoring later-born cohorts in fluid intelligence measures are widely documented for young adults. In the current study, we quantified such trends in old age using data from highly comparable participants living in a narrowly de...

Aircraft noise is a particularly problematic source of noise as many airports are located in or near major cities and, as a result, densely populated areas are affected. Data from the Berlin Aging Study II (Berliner Altersstudie II, BASE-II), whose socioeconomic module is based on the longitudinal SocioEconomic Panel (SOEP) study which has been con...

This paper estimates the causal effect of retirement on health, health behavior, and healthcare utilization. Using Regression Discontinuity Design to exploit financial incentives in the German pension system for identification, I investigate a wide range of health behaviors (e.g. alcohol and tobacco consumption, physical activity, diet and sleep) a...

The Berlin Aging Study II (BASE-II) is a multidisciplinary study that allows for the investigation of how a multitude of health status factors as well as many other social and economic outcomes interplay. The sample consists of 1,600 participants aged 60 to 80, and 600 participants aged 20 to 35. The socio-economic part of BASE-II, the so called SO...

The German health care reform implemented in 2009 led to a considerable increase in price transparency within the statutory health insurance (SHI) (Gesetzliche Krankenversicherung, GKV) system and also made it more consumer-friendly which, in turn, has encouraged policy holders to react to price hikes by switching to a different health insurance fu...

Die 2009 implementierte Gesundheitsreform hat die Preistransparenz und somit die Verbraucherfreundlichkeit innerhalb der gesetzlichen Krankenversicherung (GKV) zunächst deutlich erhöht und die Bereitschaft der Versicherten gefördert, auf Preiserhöhungen mit einem Wechsel der Krankenkasse zu reagieren. Denn mit der Einführung des Gesundheitsfonds 20...
