Impact of First Occupation on Health at Older Ages

Occupation is discussed as a social determinant of health. Occupation has received little attention in this light in the economics literature. We examine occupation in a life-course framework and use measures of first-occupation, initial health, and mother’s education. We contend that first occupation is a choice made relatively early in life that affects health outcomes at later ages. We examine first-occupation for two reasons: 1) there is growing evidence that early determinants affect later health and occupation has received little attention in this regard and 2) first occupation is predetermined in analysis of later health, which helps to address the issue of potential simultaneity. Using data from the Panel Study of Income Dynamics (PSID) we estimate the impact of initial occupation on two measures of health later in life: respondent-reported fair/poor health and ever suffering a heart attack. The PSID offers the opportunity to examine a lifecycle perspective as we can examine the impact of early occupation on later health while controlling for several predetermined conditions such as mother’s education and health in youth. Estimates suggest that first-occupation has a durable impact on later health, ceteris paribus, but that the impact varies by health measure and the set of control variables in regression specifications. Early choice of occupation could be a critical factor in successful aging and this information may pave the way to developing more effective workplace and public policies to improve health in older ages.

Work Expectations, Realizations, and Depression in Older Workers

We explore the impact on depressive symptoms of deviation in actual labor force behavior at age 62 from earlier expectations. Our sample of 4,241 observations is drawn from the Health and Retirement Study (HRS). We examine workers who were less than 62 years of age at the 1992 HRS baseline, and who had reached age 62 by our study endpoint, enabling comparison of actual labor force withdrawal with earlier expectations. Poisson regression were used to estimate the impact of expected full-time work status on depressive symptoms; regressions are estimated separately for those working fulltime at age 62 and those not working fulltime. We found significant effects on depression at age 62 both for full-time workers who expected not to be working full-time, and for participants not working full-time who expected to be doing so. These results hold even after adjustment for earlier depressive symptoms, sociodemographic and other relevant controls. The findings suggest that working longer and retiring earlier than expected each may compromise psychological well-being. The current financial crisis may result in both scenarios as some workers may have to work longer than expected due to the decline in pension and other wealth while others may retire earlier due to job loss.

Gender and age differences among current smokers in a general population survey

BACKGROUND: Evidence suggests a higher proportion of current smokers among female than among male ever smokers at the age above 50. However, little is known about the proportion of current smokers among ever smokers in old age groups with consideration of women in comparison to men from general population samples. The goal was to analyze the proportions of current smokers among female and among male ever smokers including those older than 80. METHODS: Cross-sectional survey study with a national probability household sample in Germany. Data of 179,472 participants aged 10 or older were used based on face-to-face in-home interviews or questionnaires. The proportions of current smokers among ever smokers were analyzed dependent on age, age of onset of smoking and cigarettes per day including effect modification by gender. RESULTS: Proportions of current smokers tended to be larger among female than among male ever smokers aged 40 or above. Women compared to men showed adjusted odds ratios of 1.7 to 6.9 at ages 40 to 90 or older in contrast to men. No such interaction existed for age of onset of smoking or cigarettes per day. CONCLUSION: Special emphasis should be given to current smokers among the female general population at the age of 40 or above in public health intervention

Diabetes Morbidity After Displacement

We investigate how career disruptions in terms of job loss may impact morbidity for individuals diagnosed with type 2 diabetes (T2D). Combining unique, high-quality longitudinal data from the Swedish National Diabetes Register (NDR) with matched employer-employee data, we focus on individuals diagnosed with T2D, who are established on the labor market and who lose their job in a mass layoff. Using a conditional Difference-in-Differences evaluation approach, our results give limited support for job loss having an impact on health behavior, diabetes progression and cardiovascular risk factors

The cellular composition of the human immune system is shaped by age and cohabitation.

Detailed population-level description of the human immune system has recently become achievable. We used a 'systems-level' approach to establish a resource of cellular immune profiles of 670 healthy individuals. We report a high level of interindividual variation, with low longitudinal variation, at the level of cellular subset composition of the immune system. Despite the profound effects of antigen exposure on individual antigen-specific clones, the cellular subset structure proved highly elastic, with transient vaccination-induced changes followed by a return to the individual's unique baseline. Notably, the largest influence on immunological variation identified was cohabitation, with 50% less immunological variation between individuals who share an environment (as parents) than between people in the wider population. These results identify local environmental conditions as a key factor in shaping the human immune system

Does Job Loss Make You Smoke and Gain Weight?

This paper estimates the effect of involuntary job loss on smoking behavior and body weight using German Socio-Economic Panel Study data. Baseline nonsmokers are more likely to start smoking due to job loss, while smokers do not intensify their smoking. Job loss increases body weight slightly, but significantly. In particular, single individuals as well as those with lower health or socioeconomic status prior to job loss exhibit high rates of smoking initiation. The applied regression-adjusted semiparametric difference-in-difference matching strategy is robust against selection on observables and time-invariant unobservables. This paper provides an indirect test showing that the identifying assumption is not violated in the difference-in-difference estimator. The findings are robust over various matching specifications and different choices of the conditioning variables

Health events and the smoking cessation of middle aged Americans.

This study investigates the effect of serious health events including new diagnoses of heart attacks, strokes, cancers, chronic lung disease, chronic heart failure, diabetes, and heart disease on future smoking status up to 6 years postevent. Data come from the Health and Retirement Study, a nationally representative longitudinal survey of Americans aged 51-61 in 1991, followed every 2 years from 1992 to 1998. Smoking status is evaluated at each of three follow-ups, (1994, 1996, and 1998) as a function of health events between each of the four waves. Acute and chronic health events are associated with much lower likelihood of smoking both in the wave immediately following the event and up to 6 years later. However, future events do not retrospectively predict past cessation. In sum, serious health events have substantial impacts on cessation rates of older smokers. Notably, these effects persist for as much as 6 years after a health event.This research was supported by a grant from the Robert Wood Johnson Foundation (#039787), as part of the Transdisciplinary Tobacco Use Research Center at Yal
