Abstract [en]

This paper discusses the concepts of vulnerability and susceptibility and their relevance for understanding and tackling health inequalities. Tackling socioeconomic inequalities in health is based on an understanding of how an individual's social position influences disease risk. Conceptually, there are two possible mechanisms (not mutually exclusive): there is either some cause(s) of disease that are unevenly distributed across socioeconomic groups (differential exposure) or the effect of some cause(s) of disease differs across groups (differential effect). Since differential vulnerability and susceptibility are often used to denote the latter, we discuss these concepts and their current use and suggest an epidemiologically relevant distinction. The effect of social position can thus be mediated by causes that are unevenly distributed across social groups and/or interact with social position. Recent improvements in the methodology to estimate mediation and interaction have made it possible to calculate measures of relevance for setting targets and priorities in policy for health equity which include both mechanisms, i.e. equalize exposure or equalize effects. We finally discuss the importance of differential susceptibility and vulnerability for the choice of preventive strategies, including approaches that target high-risk individuals, whole populations and vulnerable groups.

Abstract [en]

Background:

Shift work is associated with increased risk of cardiovascular disease, but the causes have not yet been fully established. It has been proposed that the coronary risk factors are more hazardous for shift workers, resulting in a potential interaction effect with shift work.

Objective:

To analyse interaction effects of work schedule and established risk factors for coronary artery disease on the risk of myocardial infarction.

Methods:

This analysis was conducted in SHEEP/VHEEP, a case-control study conducted in two counties in Sweden, comprising all first-time cases of myocardial infarction among men and women 45-70 years of age with controls stratified by sex, age, and hospital catchment area, totalling to 4648 participants. Synergy index (SI) was used as the main outcome analysis method for interaction analysis.

Results:

There was an interaction effect between shift work and physical inactivity on the risk of myocardial infarction with SI of 2.05 (95% CI 1.07 to 3.92) for male shift workers. For female shift workers, interaction effects were found with high waist-hip ratio (SI 4.0, 95% CI 1.12 to 14.28) and elevated triglycerides (SI 5.69, 95% CI 1.67 to 19.38).

Conclusion:

Shift work and some established coronary risk factors have significant interactions.

Abstract [en]

Purpose: Supportive social relations are associated with good mental health, yet few studies have considered the prospective importance of adolescent peer relations for adult mental health and the potential mechanisms involved.

Methods: Participants (n=941) were sourced from the Northern Swedish Cohort, a prospective study comprising school students aged 16 in 1981. Integrating life course epidemiology with four-way decomposition analysis, this paper considers the controlled direct effect of poor peer relations at age 16 on depressive symptoms at age 43, the pure indirect effect mediated by the availability of social support at age 30, and potential interactions between the exposure and the mediator.

Results: After controlling for gender, baseline depressive symptoms and parental socioeconomic position, poor peer relations at age 16 were associated with depressive symptoms at age 43, largely irrespective of social support at age 30. Nonetheless, poor peer relations in adolescence were associated with poorer social support at age 30, and mediation accounted for a modest proportion (pure indirect effect 10%) of the association between poor peer relations and depressive symptoms at age 43.

Conclusions: Policies to foster constructive peer relations for adolescents at school are encouraged; such policies may promote both the availability of social support and better mental health across the life course.

Abstract [en]

Introduction: Present knowledge concerning potential associations between comorbidities and the fatality of a first myocardial infarction (MI) is limited.

Aim: To identify comorbidities in 45-70-year-old individuals who suffered a first MI and died within 7 days in Stockholm County from 1992-1994. In addition, to assess how each of the comorbidities identified, as well as the number of hospitalizations during the 10-year period prior to the MI, was associated with MI fatality.

Methods: The data collected on our inception cohort of 1984 first Ml, of which 524 were fatal within 7 days, were primarily self-reported, proxy-reported by questionnaire and/or extracted from comprehensive national registers. Comorbidilies among fatal cases with a prevalence >2% were identified. Risk ratios (with 95% confidence intervals) for the association of Ml fatality with number of prior hospitalizations and specific comorbidities were calculated using binomial regression with log link. A structured review of autopsy reports on fatal cases was performed in order to identify additional indicators of comorbidities.

Results: After adjusting for sex, age and disposable income, the number of previous hospitalizations was associated with 7-day Ml fatality. Of the comorbidities identified as prevalent in fatal cases, the following were associated with 7-day fatality in crude analysis: epilepsy, heart failure, stroke, alcoholism, cancer, renal diseases, asthma, psychiatric diseases, diabetes, and rheumatoid arthritis. Indicators of comorbidities identified from autopsy data included a silent MI, severe atherosclerosis of the abdominal aorta, and hepatic steatosis. Adjustments for sex and age (although not possible for epilepsy and alcoholism), did not substantially alter results.

Conclusions: Our current findings indicate that in connection with a first MI, particular attention should be paid to those with repeated prior hospitalizations and/or epilepsy, heart failure, stroke, alcoholism, cancer, renal diseases, asthma, psychiatric diseases, diabetes and rheumatoid arthritis.

Abstract [en]

Background: Organized group activities (e.g. sports or arts clubs) have long been noted as important developmental settings for youth, yet previous studies on the relationships between participation and mental health outcomes have focused on short-term effects among school-aged adolescents. The subsequent period of life, emerging adulthood, has been largely overlooked despite being another important life stage where individuals face new existential challenges and may benefit from group activity participation. The potential for macroeconomic conditions to modify these relationships has also not been considered.

Methods: Participants (n = 1654) comprise two cohorts, born in either 1965 (n = 968) or 1973 (n = 686), from the same middle-sized industrial town in Northern Sweden. Both cohorts completed detailed questionnaires at age 21 (macroeconomic boom for Cohort 65, recession for Cohort 73) and approximately 20 years follow-up (age 43 for Cohort 65, age 39 for Cohort 73). General linear models were used to assess concurrent and prospective associations between regular group activity participation and depressive symptoms, as well as the potential interaction with boom/recession.

Results: After controlling for sociodemographic factors, regular group activity participation at age 21 was associated with lower depressive symptoms, both concurrently and at follow-up. Those exposed to recession at age 21 reported higher depressive symptoms at the time but there was no interaction between cohort (boom/recession) and group activity participation.

Conclusions: Regular group activity participation during emerging adulthood is associated with lower depressive symptoms uniformly in times of boom and recession. Beneficial effects of such participation may contribute to better mental health over 20 years.

Abstract [en]

Background Shift work has been associated with an increased risk of cardiovascular disease (CVD). However, there is a need for more studies to determine whether there is an interaction between shift work and other risk factors of CVD, thereby increasing the risk of CVD in shift workers. Aims To discern whether shift work and parental mortality from myocardial infarction (MI) or sudden cardiac death (SCD) interact to increase the risk of MI in men. Methods A case-control dataset was used to assess interaction between shift work and parental history of CVD, using death from MI or SCD, or death before age 65, on an additive scale. Results were reported as relative excess risk due to interaction, attributable proportion due to interaction (AP) and synergy index (SI). Results There was an interaction between shift work and paternal mortality from MI or SCD, when both factors were present [SI = 2.39; 95% confidence interval (CI) 1.02. 5.6 and AP = 0.4; 95% CI 0.08. 0.73]. Conclusions Paternal mortality from MI or SCD interacts with shift work to increase the risk of MI in men.

Abstract [en]

Objective: The aim of this study was to determine whether job strain, i.e. a combination of job demands and decision latitude (job control), and sleep disturbances among persons with occasional low-back pain are prognostic factors for developing troublesome low-back pain; and to determine whether sleep disturbances modify the potential association between job strain and troublesome low-back pain. Methods: A population-based cohort from the Stockholm Public Health Cohort surveys in 2006 and 2010 (n = 25,167) included individuals with occasional low-back pain at baseline 2006 (n = 6,413). Through logistic regression analyses, potential prognostic effects of job strain and sleep disturbances were studied. Stratified analyses were performed to assess modification of sleep disturbances on the potential association between job strain and troublesome low-back pain. Results: Those exposed to job strain; active job (odds ratio (OR) 1.3, 95% confidence interval (95% CI) 1.1-1.6), or high strain (OR 1.5, 95% CI 0.9-2.4) and those exposed to severe sleep disturbances (OR 3.0, 95% CI 2.3-4.0), but not those exposed to passive jobs (OR 1.1, 95% CI 0.9-1.4) had higher odds of developing troublesome low-back pain. Sleep disturbances did not modify the association between job strain and troublesome low-back pain. Conclusion: These findings indicate that active job, high job strain and sleep disturbances are prognostic factors for troublesome low-back pain. The odds of developing troublesome low-back pain due to job strain were not modified by sleep disturbance.

Abstract [en]

Background: The role of healthy lifestyle behavior (HLB) in terms of physical activity, alcohol intake, smoking, and diet put together has not yet been explored for the risk of low back pain (LBP) and neck pain (NP). Our aim was to study if an HLB is protective against the onset of long duration troublesome LBP and NP in men and women.

Methods: Two cohorts from the Stockholm Public Health Cohort, free from LBP (n=12,483) and NP (n=10,539), respectively, in 2006, were surveyed with questionnaires. Baseline information about physical activity, alcohol intake, diet, and smoking were dichotomized into being healthy/not healthy and combined in a categorical variable according to the number of healthy behaviors present. Binomial regression analyses were used to evaluate the role of HLB for the outcomes 4 years later.

Results: When men with three or four healthy lifestyles were compared to men with none or one, the risk ratio (RR) of LBP was 0.63 (95% confidence interval [CI]: 0.39-1.02). The corresponding RR for LBP in women was 0.86 (95% CI: 0.56-1.32). When men with three or four healthy lifestyles were compared to men with none or one, the RR for NP was 1.13 (95% CI: 0.74-1.71). The corresponding RR for NP in women was 0.52 (95% CI: 0.35-0.77).

Conclusion: An HLB seems to be protective for long duration troublesome LBP in men, and for long duration troublesome NP in women.
