Labour market exit routes in high- and low-educated older workers before and after social insurance and retirement policy reforms in Sweden
Few previous studies have investigated how socioeconomic differences in labour market exit have changed after restrictions in social insurance policies. The aim of this register-based study is to investigate how early labour market exit pathways among older men and women with different levels of education changed after major restrictive social insurance and retirement policy reforms in Sweden. Cohort 1 (pre-reform) consisted of individuals who we…
Do early life factors explain the educational differences in early labour market exit? A register-based cohort study
The association between education and early exit due to disability pension, long-term sickness absence and long-term unemployment was to a large part explained by factors from early life. However, this was not seen for early old-age retirement. These results indicate the importance of taking a life-course perspective when examining labour market participation in later working life
Trends in Precarious Employment in Sweden 1992–2017
The aim of this study was to identify trends in precarious employment in the Swedish workforce from 1992 to 2017. This is a repeated cross-sectional study, analyzing the total working population aged 16-75 in Sweden at five-year intervals. We used version 2.0 of the Swedish Register-based Operationalization of Precarious Employment, covering the following dimensions: employment insecurity, income inadequacy, lack of rights and protection. The pro…
Educational qualification differences and early labor market exit among men
Exposure to labor market marginalization across the working life was important in explaining educational differences in early labor market exit due to disability pension or sickness absence and unemployment. This study underscores the importance of identifying and implementing preventive measures in the workplace (e.g. adaptions) to prevent new spells of sickness absence and unemployment, especially among low educated individuals
What is precarious employment? A systematic review of definitions and operationalizations from quantitative and qualitative studies
Death of a Parent During Childhood and the Risk of Ischemic Heart Disease and Stroke in Adult Men
OBJECTIVE: The death of a parent during childhood is a severe life event with potentially long-term consequences. Earlier studies have shown an increased risk of cardiovascular diseases (CVD) after the death of a spouse, child, or sibling. Whether parental death during childhood is associated with an increased risk of incident CVD is unknown and was investigated in this study. METHODS: We studied 48,992 men born 1949 to 1951 and enlisted for mili…
Educational differences in labor market marginalization among mature-aged working men
Educational differences remained regarding LMM among mature-aged workers, even after considering several important risk factors measured across the life course. Previous health problems and disrupted employment histories explained the largest part of the associations
Childhood IQ and mortality during 53 years’ follow-up of Swedish men and women
BACKGROUND: The association between childhood cognitive ability measured with IQ tests and mortality is well documented. However, studies on the association in women are few and conflicting, and the mechanisms underlying the association are unclear. METHODS: Data on IQ were collected at school at age 13 among 19 919 men and women born in 1948 and 1953. Information on childhood socioeconomic position, the participants' socioeconomic and social cir…
Long-term effects of youth unemployment on mental health
BACKGROUND: Ill health is a risk factor and a consequence of unemployment, which might vary depending on the national rate of unemployment. We investigated the long-term effect of youth unemployment on mental health and explored the possible interaction during periods of high (economic crisis) and low (non-crisis) unemployment rates. METHODS: A register-linked population-based cohort study was conducted including individuals aged 17-24 years. The…
Fathers’ intelligence measured at age 18–20 years is associated with offspring smoking
BACKGROUND: An association between lower IQ of parents, measured early in life, and smoking among their offspring has been reported. The extent to which other background factors account for this association is unknown. METHODS: Data on IQ, smoking, mental health, social class, parental divorce and social problems in a cohort of men born during 1949-1951 and conscripted for military service in 1969 were linked to smoking data on 682 offspring inte…
IQ and alcohol-related morbidity and mortality among Swedish men and women
There was an inverse, graded association between IQ and alcohol-related disease and death, which at least partially was mediated by social position as an adult. For alcohol-related death, complete mediation by socioeconomic position as an adult was found. Gender does not moderate this association. The role of socioeconomic position may differ between the genders
Does high intelligence improve prognosis? The association of intelligence with recurrence and mortality among Swedish men with coronary heart disease
BACKGROUND: Lower intelligence early in life is associated with increased risks for coronary heart disease (CHD) and mortality. Intelligence level might affect compliance to treatment but its prognostic importance in patients with CHD is unknown. METHODS: A cohort of 1923 Swedish men with a measure of intelligence from mandatory military conscription in 1969-1970 at age 18-20, who were diagnosed with CHD 1991-2007, were followed to the end of 200…
Sick leave and the impact of job-to-job mobility on the likelihood of remaining on the labour market - a longitudinal Swedish register study
The present study indicates that for those on long-term sick leave that changed workplaces, the opportunities to stay on the labour market might increase. However, the study has methodological limitations and the results for men are ambiguous. We do not therefore have enough evidence for recommending job change as a strategy for vocational rehabilitation
The effect of childhood socioeconomic position on alcohol-related disorders later in life
BACKGROUND: Alcohol use is the third most important global-health risk factor and a main contributor to health inequalities. Previous research on social determinants of alcohol-related disorders has delivered inconsistent results. We aimed to investigate whether socioeconomic position (SEP) in childhood predicts alcohol-related disorders in young adulthood in a Swedish national cohort. METHODS: We studied a register-based national cohort of Swedi…
Educational differences in disability pension among Swedish middle-aged men
BACKGROUND: The association between level of education and disability pension (DP) is well known. Earlier studies have investigated the importance of early life factors and work characteristics but not in combination. The aim of this study was to investigate the association between level of education and DP among Swedish middle-aged working men and to what extent such an association can be explained by factors measured in late adolescence and wor…
P1-521 IQ in childhood and later risk of alcohol-related disease and death
Introduction While much research has been performed on associations between intelligence and several different health outcomes, there is as yet no conclusive evidence regarding the association between intelligence and alcohol-related disease and death. Furthermore, most studies have been performed on men. The aim of this study is to further investigate the association between IQ and alcohol-related morbidity and mortality and to explore if there …
Unemployment and mortality—a longitudinal prospective study on selection and causation in 49321 Swedish middle-aged men
BACKGROUND: Unemployment is associated with increased risk of mortality. It is, however, not clear to what extent this is causal, or whether other risk factors remain uncontrolled for. The aim of this study was to investigate the association between unemployment and all-cause and cause-specific mortality, adjusting for indicators of mental disorder, behavioural risk factors and social factors over the life course. METHODS: This study was based on…
Cognitive ability in adolescence and mortality in middle age
BACKGROUND: An association between childhood cognitive ability measured by IQ tests and mortality has been reported recently. It is not clear from those studies to what extent the increased relative risk associated with lower IQ scores may be attenuated by adjustment for other risk factors. This study aims to investigate the association between cognitive ability measured at age 18-20 years and mortality among middle-aged men adjusting for risk fa…
The association between masculinity rank and mortality patterns
BACKGROUND: Being male constitutes a risk factor for early death, and this may be connected to concepts of masculinity. The objective of the present study was to investigate the association between masculinity rank during late adolescence and mortality patterns in a cohort of 49 321 Swedish men tested for compulsory military training in 1969. METHODS: The measure of masculinity consisted of a five-grade ranking from the conscription information t…
How Does IQ Affect Onset of Smoking and Cessation of Smoking—Linking the Swedish 1969 Conscription Cohort to the Swedish Survey of Living Conditions
OBJECTIVE: To examine the association between intelligence quotient (IQ) measured at ages 18 to 20 and onset of smoking, and the association between IQ and smoking cessation. METHODS: Data on IQ, smoking, mental health, and social background among 49,321 Swedish men born 1949 to 51, collected at conscription for military service in 1969, were used. The association between IQ and smoking cessation was investigated among those 694 members of the fu…
