Education leads to a more physically active lifestyle: Evidence based on Mendelian randomization.

Physical inactivity is a major health risk worldwide. Observational studies suggest that higher education is positively related to physical activity, but it is not clear whether this relationship constitutes a causal effect. Using participants (N = 1651) drawn from the Cardiovascular Risk in Young Finns Study linked to nationwide administrative data from Statistics Finland, this study examined whether educational attainment, measured by years of education, is related to adulthood physical activity in terms of overall physical activity, weekly hours of intensive activity, total steps per day, and aerobic steps per day.

Do childhood infections affect labour market outcomes in adulthood and, if so, how?

A burgeoning body of literature suggests that poor childhood health leads to adverse health outcomes, lower educational attainment and weaker labour market outcomes in adulthood. We focus on an important but under-researched topic, which is the role played by infection-related hospitalization (IRH) in childhood and its links to labour market outcomes later in life. The participants aged 24-30 years in 2001 N = 1706 were drawn from the Young Finns Study, which includes comprehensive registry data on IRHs in childhood at ages 0-18 years.

Moving to become healthier?

This paper examines individuals' health and whether it improves when individuals move from a region with poorer health on average to a region with better health on average. We used data from Finland, which is a country with large regional differences in health behaviours and outcomes. We found no evidence that moving from a less healthy region to a healthier region would have any significant effect on the health of individuals who move compared with the health of other individuals.

Self-reported health versus biomarkers: does unemployment lead to worse health?

Objectives: This paper examines the relationship between unemployment and health using both subjective and biometric information on health status.

Study Design: Longitudinal panel data.

Methods: We compare the results of regressions of unemployment on self-reported health with those of regressions of unemployment on health as measured with biomarkers (hypertension and levels of blood glucose and C-reactive protein).

Employment Status and Personal Income Before and After Onset of a Severe Mental Disorder: A Case-Control Study.

Objective: Individuals with severe mental disorders have an impaired ability to work and are likely to receive income transfer payments as their main source of income. However, the magnitude of this phenomenon remains unclear. Using longitudinal population cohort register data, the authors conducted a case-control study to examine the levels of employment and personal income before and after a first hospitalization for a serious mental disorder.

Alternative measures of body composition and wage premium: New evidence from Indonesia.

This paper examines the relationship between body composition and earnings in a developing country setting. We use body mass index, waist circumference and hip circumference. Exploiting the panel structure of our longitudinal survey, we find that along with BMI, waist circumference is related to higher earnings in Indonesia.

Mental disorders and long-term labour market outcomes: nationwide cohort study of 2 055 720 individuals.

Objective: To examine the associations between an onset of serious mental disorders before the age of 25 with subsequent employment, income and education outcomes.

Methods: Nationwide cohort study including individuals (n = 2 055 720) living in Finland between 1988-2015, who were alive at the end of the year they turned 25. Mental disorder diagnosis between ages 15 and 25 was used as the exposure.

Health endowment and later-life outcomes in the labour market: Evidence using genetic risk scores and reduced-form models.

This paper examines the relationship between health endowment and later-life outcomes in the labour market. The analysis is based on reduced-form models in which labour market outcomes are regressed on genetic variants related to the increased risk of cardiovascular diseases. We use linked Finnish data that have many strengths.

The effect of weight on labor market outcomes: An application of genetic instrumental variables.

This paper contributes to the literature on the labor market consequences of obesity by using a novel instrument: genetic risk score, which reflects the predisposition to higher body mass index (BMI) across many genetic loci. We estimate instrumental variable models of the effect of BMI on labor market outcomes using Finnish data that have many strengths, for example, BMI that is measured rather than self-reported, and data on earnings and social income transfers that are from administrative tax records and are thus free of the problems associated with nonresponse, reporting error or top coding. The empirical results are sensitive to whether we use a narrower or broader genetic risk score, and to model specification.

Harsh times: do stressors lead to labor market losses?

This paper examines the links between stressful life events and labor market outcomes. We use twin data for Finnish men and women combined with register-based individual information on earnings, employment and social income transfers. The twin data allow us to account for shared environmental and genetic confounders.

Does education protect against depression? Evidence from the Young Finns Study using Mendelian randomization.

Using participants (N = 1733) drawn from the nationally representative longitudinal Young Finns Study (YFS) we estimate the effect of education on depressive symptoms. In 2007, when the participants were between 30 and 45 years old, they reported their depressive symptoms using a revised version of Beck's Depression Inventory. Education was measured using register information on the highest completed level of education in 2007, which was converted to years of education.

If you drink, don't smoke: Joint associations between risky health behaviors and labor market outcomes.

This paper examines the links between risky health behaviors and labor market success. We provide new evidence on the joint relationships between the most prominent forms of risky health behavior - alcohol consumption, smoking and physical inactivity - and long-term labor market outcomes. We use twin data for Finnish men and women linked to register-based individual information on earnings and labor market attachment.

Health and retirement age: Comparison of expectations and actual retirement.

Aim: We examine the relationship between the subjective assessment of health status and retirement by using information on expected and actual retirement ages.

Methods: Subjective data from cross-sectional surveys, conducted in Finland in 2003 and 2008, are linked to information on actual retirement age from register data from 2003 to 2013. Regression models are estimated for actual and expected retirement ages.

Unfit for work: Health and labour-market prospects.

Aim: The aim of this study was to examine whether health status (number of chronic diseases, health shock and use of tranquilizers/sleeping pills) is related to labour-market outcomes later in life.

Methods: Twin data for Finnish men and women who were at least 33 years old in 1990 were linked to comprehensive register-based information on unemployment and the incidence of disability pension. We used the within-twin dimension of the data to account for shared family and genetic factors.

Gene-environment interactions between education and body mass: Evidence from the UK and Finland.

More education is associated with a lower body mass index (BMI) and likelihood of being overweight. However, since a large proportion of the variation in body mass is due to genetic makeup, it has been hypothesized that education may moderate the genetic risk. We estimate main associations between (i) education, (ii) genetic risk, and (iii) interactions between education and genetic risk on BMI and the probability of being overweight in the UK and Finland.

The biometric antecedents to happiness.

It has been suggested that biological markers are associated with human happiness. We contribute to the empirical literature by examining the independent association between various aspects of biometric wellbeing measured in childhood and happiness in adulthood. Using Young Finns Study data (n = 1905) and nationally representative linked data we examine whether eight biomarkers measured in childhood (1980) are associated with happiness in adulthood (2001).

Does higher education protect against obesity? Evidence using Mendelian randomization.

Objectives: The aim of this explorative study was to examine the effect of education on obesity using Mendelian randomization.

Methods: Participants (N=2011) were from the on-going nationally representative Young Finns Study (YFS) that began in 1980 when six cohorts (aged 30, 33, 36, 39, 42 and 45 in 2007) were recruited. The average value of BMI (kg/m) measurements in 2007 and 2011 and genetic information were linked to comprehensive register-based information on the years of education in 2007.

Genetic endowments, parental resources and adult health: Evidence from the Young Finns Study.

This paper uses longitudinal survey data linked to administrative registers to examine socioeconomic gradients in health, particularly whether the effects of genetic endowments interact with the socioeconomic resources of the parental household. We find that genetic risk scores contribute to adult health measured by biomarkers. This result is consistent with the findings from genome-wide association studies.

Preventing Sickness Absence With Career Management Intervention: A Randomized Controlled Field Trial.

This study examined whether a group intervention focusing on building up preparedness for career management can prevent future sickness absence.Register-based data on the number of sickness absence days and sickness absence episodes were examined as outcomes of the intervention among 684 employees in 17 organizations in a randomized controlled trial. Sickness absence data were collected covering a period from 1 year before (baseline) to approximately 2 years after the intervention (follow-up).

Stature and long-term labor market outcomes: Evidence using Mendelian randomization.

We use the Young Finns Study (N=∼2000) on the measured height linked to register-based long-term labor market outcomes. The data contain six age cohorts (ages 3, 6, 9, 12, 15 and 18, in 1980) with the average age of 31.7, in 2001, and with the female share of 54.

Changes in Income at Macro Level Predict Sex Ratio at Birth in OECD Countries.

The human sex ratio at birth (SRB) is approximately 107 boys for every 100 girls. SRB was rising until the World War II and has been declining slightly after the 1950s in several industrial countries. Recent studies have shown that SRB varies according to exposure to disasters and socioeconomic conditions.

Depressive symptoms and long-term income: The Young Finns Study.

Background: Higher depressive symptoms have been associated with lower future income. However, studies examining this issue have had limited follow-up times and have used self-reported measures of income. Also, possible confounders or mediators have not been accounted.

Devil in disguise: Does drinking lead to a disability pension?

Objectives: To examine whether alcohol consumption in adulthood is related to the incidence of receiving a disability pension later in life.

Methods: Twin data for Finnish men and women born before 1958 were matched to register-based individual information on disability pensions. Twin differences were used to eliminate both shared environmental and genetic factors.

The Education-health Nexus: Fact and fiction.

This paper examines the link between schooling and health. We provide new evidence on the relationship between formal schooling completed and several aspects of health by using Finnish twin data matched to individual information on schooling. Health is measured in 1990 (and 1981).
