Virtanen P, Nummi T, Janlert U, Hammarström A. Psychosocial conditions during school-age as determinants of long-term labour market attachment: a study of the Northern Swedish Cohort from the 1980s to the 2020s. BMC Public Health 2024; 24:191. [PMID: 38229043 PMCID: PMC10790433 DOI: 10.1186/s12889-023-17611-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 12/28/2023] [Indexed: 01/18/2024] Open
Abstract
BACKGROUND This study, conducted on a Swedish population cohort, explores how internalized (depressive and functional somatic) and externalized (smoking, drinking, truancy, vandalism, delinquency) mental health symptoms, as well as close interpersonal relations (family climate and school connectedness) reported during adolescence, influence the work-life course up to late midlife. METHODS We examined repeated measurements of labour market status from age 16 to 56 using sequence analyses. We identified five different labour market attachment (LMA16-56) trajectories, namely 'strong,' 'early intermediate,' 'early weak,' 'late weak,' and 'constantly weak.' Multinomial logistic regressions were employed to relate each of the nine determinants to the identified trajectories. RESULTS When compared to the risk of 'strong' LMA16-56, adversity in all conditions, except for vandalism, entailed a higher risk of the 'constantly weak' trajectory. Moreover, all conditions, except for functional somatic symptoms, entailed a higher risk of the 'late weak' LMA16-56. The risk of the 'early intermediate' LMA16-56 was non-significant across all the conditions. CONCLUSIONS This study contributes to existing knowledge through its novel exploration of labour market attachment and the revelation of the significance of proximal interpersonal relationships in attachment outcomes. Additionally, the study reaffirms the importance of externalizing behaviour, while suggesting that internalized symptoms in adolescence might have a less influential, though not negligible, role. These results underscore the importance of addressing acting out behaviour and nurturing human relationships during compulsory basic education, when the entire age group is still within reach. This approach aims not only to reduce frictions in the school-to-work transition but also to prevent midlife labour market attachment problems that may arise with delayed intervention.

Abstract
Background Little is known about factors that may explain the association between depressive symptoms and poor labour market participation (LMP). The aim of this study is to examine the mediation and interaction effects of social support on the association between depressive symptoms and LMP. Methods Data were used from 985 participants (91% of the initial cohort) of the Northern Swedish Cohort, a longitudinal study of Swedish participants followed from adolescence throughout adulthood. Depressive symptoms were measured at age 16, social support at age 21 and LMP from age 30 to 43. Poor LMP was defined as being unemployed for a total of 6 months or more between the ages of 30 and 43. A four-way decomposition approach was applied to identify direct, mediation and interaction effects, together and separately. Results Both depressive symptoms during adolescence and social support at young adulthood were associated with poor LMP [odds ratio (OR) = 1.70, 95% confidence interval (CI) 1.17–2.47 and OR = 2.56, 95% CI 1.78-3.68 respectively]. The association between depressive symptoms and poor LMP was partially mediated by a lack of social support. No interaction effect of a lack of social support was found. Conclusion The results suggest that depressive symptoms influence not only later LMP but also the intermediary level of social support, and in turn influencing later LMP. Recommendations for public health are to detect and treat depressive symptoms at an early stage and to focus on the development of social skills, facilitating the increased availability of social support, thereby improving future LMP.

Abstract
The main goal of this paper is to address how different partnership statuses impact the likelihood of death among mature adults and elderly persons in Spain circa 2012 using a massive new dataset of administrative registers linked to census data. First, gross and net effects of having a partner on mortality risks of partnered and non-partnered persons are evaluated; then the characteristics and the importance of selection and protection effects of marriage and partnership with regard to the likelihood of death are assessed. We make use of exact matching methods in order to avoid the selection bias associated with the non-random assignment of persons to different partnership statuses. Protection effects decline gradually with age, but always remain positive. Selection effects show a far more pronounced decline with age leading to a pattern in which selection is much stronger than protection during the mature adult ages, but then disappear entirely and even become negative as people age. While both sexes show similar patterns, the protection effect is slightly higher among men while the selection effect is much higher among women, especially before 65 years of age.

Abstract
BACKGROUND Research indicate that social class mobility could be potentially important for health, but whether this is due to the movement itself or a result of people having been integrated in different class contexts is, to date, difficult to infer. In addition, although several theories suggest that transitions between classes in the social hierarchy can be stressful experiences, few studies have empirically examined whether such movements may have health effects, over and above the implications of "being" in these classes. In an attempt to investigate whether intragenerational social mobility is associated with functional somatic symptoms in mid-adulthood, the current study tests three partially contrasting theories. METHOD The dissociative theory suggests that mobility in general and upward mobility in particular may be linked to psychological distress, while the falling from grace theory indicates that downward mobility is especially stressful. In contrast, the acculturation theory holds that the health implications of social mobility is not due to the movement itself but attributed to the class contexts in which people find themselves. Diagonal Reference Models were used on a sample of 924 individuals who in 1981 graduated from 9th grade in the municipality of Luleå, Sweden. Social mobility was operationalized as change in occupational class between age 30 and 42 (measured in 1995 and 2007). The health outcome was functional somatic symptoms at age 42, defined as a clustering self-reported physical symptoms, palpitation and sleeping difficulties during the last 12 months. RESULTS Overall mobility was not associated with higher levels of functional somatic symptoms compared to being immobile (p = 0.653). After controlling for prior and current class, sex, parental social position, general health, civil status, education and unemployment, the association between downward mobility was borderline significant (p = 0.055) while upward mobility was associated with lower levels of functional somatic symptoms (p = 0.03). CONCLUSION The current study did not find unanimous support for any of the theories. Nevertheless, it sheds light on the possibility that upward mobility may be beneficial to reduce stress-related health problems in mid-life over and above the exposure to prior and current class, while downward mobility can be of less importance for middle-age health complaints.

Abstract
OBJECTIVES Little is known on long-term consequences of poor social relationships in adulthood. The study aimed to examine associations between social relationships at age 30 and internalising symptoms at age 42. METHODS Data was drawn from four waves of the Northern Swedish cohort (n = 1001, 94 % response rate). The outcome internalising symptoms was measured by a composite index of depressiveness and anxiety. A cumulative measure was constructed to reflect various aspects of social relationships. Multivariate ordinal logistic regressions were used, controlling for socioeconomic indicators and previous level of internalising symptoms. RESULTS An accumulation of poor social relationships indicators at age 30 is related to internalising symptoms at age 42 in women (OR 1.30; CI 1.11-1.52) and men (OR 1.17; CI 1.02-1.36). The associations remained significant after adjustment for covariates. CONCLUSIONS Poor quality of social relationships at age 30 can predict internalising symptoms 12 years later in both men and women even when previous mental health as well as financial disadvantage is accounted for. More research is required to further examine pathways and mechanisms as well as suitable interventions.

Abstract
BACKGROUND Most previous studies on the effects of length of unemployment on health have focused on the duration of continuous spells of unemployment rather than on the cumulative length of intermittent spells. This study analysed the relationship between the cumulative length of intermittent spells of unemployment and different health-related outcomes using data from a longitudinal study of school leavers. METHODS All pupils who completed compulsory schooling in 1981 in a medium-sized town in northern Sweden (N = 1083) were followed for 14 years with repeated questionnaires including questions about unemployment, health and health behaviour. RESULTS Men tended to react with a steady state or a levelling off of health symptoms with increased unemployment, whereas women showed deteriorating health symptoms. For health behaviour the reverse occurred. Women's health behaviour was less connected with increased unemployment while men's health behaviour tended to deteriorate. CONCLUSION Cumulative length of unemployment is correlated with deteriorated health and health behaviour. Long-term unemployment, even as a result of cumulated shorter employment spells over a number of years should be an urgent target for policy makers.

Abstract
BACKGROUND The importance of social and avoidable determinants of depressive symptoms has been increasingly recognized in public health research. However, when it comes to determinant of gender differences in depressive symptoms the focus is predominantly on biological unavoidable determinants. Thus, there is a need for more focus on gendered social determinants of health. The aim of this study was to analyse the importance of gender relations for depressive symptoms after taking socioeconomic factors and earlier depressive symptoms into account in the Northern Swedish cohort. METHODS A 26-year follow-up study of a cohort of all school leavers in a middle-sized industrial town in Northern Sweden was performed from age 16 until age 42. Of those still alive of the original cohort, 94% participated during the whole period and answered extensive questionnaires. Exposure was measured as socioeconomic status, financial strain, perceived gender inequity in the couple relationship and division of responsibility for domestic work. The outcome was depressive symptoms at age 42, while depressive symptoms were controlled at age 30. RESULTS In multivariate logistic regression analyses significant relations between financial strain and, among women only, also perceived gender equity in the couple relationship and depressive symptoms after adjustment for earlier health status, as well as for all other exposure measures. CONCLUSIONS Financial strain, and among women, also gender inequity in the couple relationship was related to depressive mood. There is a need to pay more attention to gender relations in future research on social determinants of depressive mood.

Abstract
Background It has been argued that the association between job strain and health could be confounded by early life exposures, and studies have shown early adversity to increase individual vulnerability to later stress. We therefore investigated if early life exposure to adversity increases the individual's physiological vulnerability job strain in adulthood. Methodology/Principal Findings In a population-based cohort (343 women and 330 men, 83% of the eligible participants), we examined the association between on the one hand exposure to adversity in adolescence, measured at age 16, and job strain measured at age 43, and on the other hand allostatic load at age 43. Adversity was operationalised as an index comprising residential mobility and crowding, parental loss, parental unemployment, and parental physical and mental illness (including substance abuse). Allostatic load summarised body fat, blood pressure, inflammatory markers, glucose, blood lipids, and cortisol regulation. There was an interaction between adversity in adolescence and job strain (B = 0.09, 95% CI 0.02 to 0.16 after adjustment for socioeconomic status), particularly psychological demands, indicating that job strain was associated with increased allostatic load only among participants with adversity in adolescence. Job strain was associated with lower allostatic load in men (β = −0.20, 95% CI −0.35 to −0.06). Conclusions/Significance Exposure to adversity in adolescence was associated with increased levels of biological stress among those reporting job strain in mid-life, indicating increased vulnerability to environmental stressors.

Abstract
PURPOSE Earlier research on health-related selection in the labour market has concentrated on selection of those with poor health into unemployment. The purpose of the present study was to investigate if suboptimal health also predicts non-permanent employment. METHODS A population cohort of 517 men and 477 women was surveyed at age 30 and at age 43 about their health and yearly employment. Non-permanent employment during the follow-up was assessed for its occurrence with Cox regression and for the amount (accumulation in months) with generalised linear models. RESULTS Suboptimal self-rated health, sense functioning and sleep quality in women and suboptimal mood in men predicted high accumulation of non-permanent employment. By contrast, in men, suboptimal self-rated health and sense functioning predicted low accumulation. The gender differences were statistically significant. Smoking predicted high occurrence and accumulation of non-permanent employment equally in men and women, whereas no associations were seen with overweight and alcohol consumption. CONCLUSIONS Selection into non-permanent employment was shown for several indicators of suboptimal health. A gendered pattern was found, with more health selection among women. The findings of this pioneering study should be tested with further research.

Abstract
Introduction Limited existing research on gender inequities suggests that for men workplace atmosphere shapes wellbeing while women are less susceptible to socioeconomic or work status but vulnerable to home inequities. Methods Using the 2007 Northern Swedish Cohort (n = 773) we identified relative contributions of perceived gender inequities in relationships, financial strain, and education to self-reported health to determine whether controlling for sex, examining interactions between sex and other social variables, or sex-disaggregating data yielded most information about sex differences. Results and Discussion Men had lower education but also less financial strain, and experienced less gender inequity. Overall, low education and financial strain detracted from health. However, sex-disaggregated data showed this to be true for women, whereas for men only gender inequity at home affected health. In the relatively egalitarian Swedish environment where women more readily enter all work arenas and men often provide parenting, traditional primacy of the home environment (for women) and the work environment (for men) in shaping health is reversing such that perceived domestic gender inequity has a significant health impact on men, while for women only education and financial strain are contributory. These outcomes were identified only when data were sex-disaggregated.

Abstract
AIMS Research often fails to ascertain whether men and women are equally hit by the health consequences of unemployment. The aim of this study was to analyze whether men's self-reported health and health behaviour were hit more by unemployment than women's in a follow-up of the Northern Swedish Cohort. METHODS A follow-up study of a cohort of all school leavers in a middle-sized industrial town in northern Sweden was performed from age 16 to age 42. Of those still alive of the original cohort, 94% (n = 1,006) participated during the whole period. A sample was made of participants in the labour force and living in Sweden (n = 916). Register data were used to assess the length of unemployment from age 40 to 42, while questionnaire data were used for the other variables. RESULTS In multivariate logistic regression analyses significant relations between unemployment and mental health/smoking were found among both women and men, even after control for unemployment at the time of the investigation and indicators of health-related selection. Significant relations between unemployment and alcohol consumption were found among women, while few visits to a dentist was significant among men. CONCLUSIONS Men are not hit more by the health consequences of unemployment in a Swedish context, with a high participation rate of women in the labour market. The public health relevance is that the study indicates the need to take gendered contexts into account in public health research.

Abstract
OBJECTIVE The general aim of this study was to explore the associations between foreign extraction and subjective health complaints (SHC) among school-aged children in Sweden. METHODS Data were obtained from the global cross-sectional survey Health Behaviour in School-aged Children (HBSC), 1997/1998, 2001/2002, and 2005/2006. A total of 11,972 pupils in grades 5, 7 and 9 participated in the survey. Logistic regression analyses were used to estimate remaining risk of SHC among the subgroups of pupils. The analyses were adjusted for socio-demographic indicators, grade and measurement year. RESULTS Parental background: Swedish n = 9,585, mixed n = 1,263, and foreign n = 1,124. The results showed an increased risk of SHC among girls with a foreign background OR 1.27 (95% CI 1.04-1.55) compared with girls with a Swedish background and among girls in single-adult households OR 1.42 (95% CI 1.20-1.67) compared with girls in two-adult households. No such differences were shown among boys. CONCLUSIONS A significantly increased risk of ill health remained in girls of foreign background after adjustment for socio-demographic indicators, grade and measurement year.

Abstract
Aims: There is a lack of empirical studies assessing the possible impact of active labour market programmes (ALMP) on health. The aim of this study was to analyze whether participation in ALMP, in contrast to being unemployed and not participating in ALMP (UNALMP), was related to mental health at different ages. Methods: The study was carried out in a medium-sized industrial town in the north of Sweden. The cohort, consisting of all 1,083 pupils who attended or should have attended the last year of compulsory school in 1981, was followed up at the ages of 16, 18, 21 and 30. Data on 381 individuals at age 21, and 281 at age 30 were used in the study. The main health measurement was psychological symptoms among participants of ALMP in contrast to UNALMP at ages 21 and 30, and was analyzed by propensity score matching method (PSM) and multivariate logistic regression. Results: Generally, ALMP had higher scores of psychological symptoms than UNALMP. Nevertheless, participation in ALMP was not related to mental health. Due to methodological shortages our results have to be interpreted with caution. Adjustment for either all background selection variables or the propensity score in multivariate logistic regression showed similar associations, suggesting that propensity score could be used to adjust for background selection variables. Conclusions: There is a need for more well-designed studies, using a theoretical framework, within the field, that are based on larger samples.

Abstract
BACKGROUND Despite the inconsistent findings of the growing amount of research analysing the possible health consequences of temporary employment, there is a lack of heterogeneous perspectives. The aim of the study was to analyse whether the health consequences of temporary employment are worse among low educated compared with high educated, after control for health-related selection. METHODS A 26-year follow-up study of a cohort of all school leavers in a middle-sized industrial town in northern Sweden was performed between 1981 and 2007. Of those still alive of the original cohort, 94% participated during the whole period. For this study, a sample of participants with temporary and permanent employment contracts between the age of 30 and 42 years was selected (n = 660). RESULTS In multivariate logistic regression analyses, an additive synergistic interaction effect was found for low education and high exposure to temporary employment in relation to suboptimal self-rated health, after controlling for health-related selection and sex. An additive antagonistic interaction was found between low education in combination with high exposure to temporary employment in relation to psychological distress, whereas no interaction was found for depressive symptoms. CONCLUSION Our hypothesis regarding worse health effects of temporary employment among low educated was partly confirmed. Our results indicate the need to analyse temporary employment from a more heterogeneous perspective as well as in relation to different health outcomes.

Abstract
Background During the past two decades, the hypothesis of fetal origins of adult disease has received considerable attention. However, critique has also been raised regarding the failure to take the explanatory role of accumulation of other exposures into consideration, despite the wealth of evidence that social circumstances during the life course impact on health in adulthood. The aim of the present prospective cohort study was to examine the contributions of birth weight and life course exposures (cumulative socioeconomic disadvantage and adversity) to dyslipidemia and serum lipids in mid-adulthood. Methods A cohort (effective n = 824, 77%) was prospectively examined with respect to self-reported socioeconomic status as well as stressors (e.g., financial strain, low decision latitude, separation, death or illness of a close one, unemployment) at the ages of 16, 21, 30 and 43 years; summarized in cumulative socioeconomic disadvantage and cumulative adversity. Information on birth weight was collected from birth records. Participants were assessed for serum lipids (total cholesterol, low- and high-density lipoprotein cholesterol and triglycerides), apolipoproteins (A1 and B) and height and weight (for the calculation of body mass index, BMI) at age 43. Current health behavior (alcohol consumption, smoking and snuff use) was reported at age 43. Results Cumulative life course exposures were related to several outcomes; mainly explained by cumulative socioeconomic disadvantage in the total sample (independently of current health behaviors but attenuated by current BMI) and also by cumulative adversity in women (partly explained by current health behavior but not by BMI). Birth weight was related only to triglycerides in women, independently of life course exposures, health behaviors and BMI. No significant association of either exposure was observed in men. Conclusions Social circumstances during the life course seem to be of greater importance than birth weight for dyslipidemia and serum lipid levels in adulthood.

Abstract
BACKGROUND The hypothesis of fetal origins of adult disease has during the last decades received interest as an explanation of chronic, e.g. cardiovascular, disease in adulthood stemming from fetal environmental conditions. Early programming and enduring dysregulations of the hypothalamic-pituitary-adrenal (HPA axis), with cortisol as its end product, has been proposed as a possible mechanism by which birth weight influence later health status. However, the fetal origin of the adult cortisol regulation has been insufficiently studied. The present study aims to examine if body size at birth is related to circadian cortisol levels at 43 years. METHODS Participants were drawn from a prospective cohort study (n = 752, 74.5%). Salivary cortisol samples were collected at four times during one day at 43 years, and information on birth size was collected retrospectively from delivery records. Information on body mass during adolescence and adulthood and on health behavior, medication and medical conditions at 43 years was collected prospectively by questionnaire and examined as potential confounders. Participants born preterm or < 2500 g were excluded from the main analyses. RESULTS Across the normal spectrum, size at birth (birth weight and ponderal index) was positively related to total (area under the curve, AUC) and bedtime cortisol levels in the total sample. Results were more consistent in men than in women. Descriptively, participants born preterm or < 2500 g also seemed to display elevated evening and total cortisol levels. No associations were found for birth length or for the cortisol awakening response (CAR). CONCLUSIONS These results are contradictory to previously reported negative associations between birth weight and adult cortisol levels, and thus tentatively question the assumption that only low birth weight predicts future physiological dysregulations.

Abstract
Although the health risk of socioeconomic disadvantage over the life-course is fairly established, the mechanisms are less studied. One candidate pathway is long-term dysregulation of cortisol. This study assesses whether socioeconomic trajectories from adolescence to adulthood influences the regulation of cortisol in mid-adulthood, and further investigates the importance of adolescence as a critical period and of accumulation of socioeconomic disadvantage. Participants were drawn from a 27-year prospective cohort study (n=732, 68% of the original cohort). Information on socioeconomic status (SES) was collected at the ages of 16 (based on parental occupation), 21, 30 and 43 (based on own occupation) years, and at 43 years participants collected one-day salivary cortisol samples at awakening, after 15min, before lunch and at bedtime. We found that the cortisol awakening response (CAR) differed with respect to SES trajectory; those with stable low or early low/upwardly mobile SES tended to display higher CAR than those with early high/downwardly mobile, highly mobile or stable high trajectories. Further analyses revealed that early low SES was related to higher CAR, and in women low SES was related to lower bedtime cortisol, independently of later SES and potential confounders. We found no support for a linear effect of accumulation of socioeconomic disadvantage. In conclusion, our study gives support for an independent effect of low socioeconomic status early in life, on the regulation of cortisol in adulthood.

Abstract
Background and objectives: Health selection into unemployment may be either direct or operate by reference to health-related behaviours rather than health per se (indirect selection). Panel data are desirable to investigate selection effects, and the two types of selection processes may be concurrent. We examine jointly the roles of health and health-related behaviours as precursors of unemployment, in order to disentangle direct from indirect selection processes. Design: The data of a multi-round nationally representative health survey in France were analysed longitudinally, based on three data collection rounds: 1992–5, 1996–8 and 2000–2. Following employees salaried in the private sector and aged 30–54 years at baseline, we explored through logistic regression the influence of non-optimal self-rated health, smoking and obesity on the risk of being found unemployed 4 years later. Results: After adjustment for self-rated health, obesity was found to be a significant precursor of unemployment in women, and heavy smoking had that role in men. After adjustment for smoking and obesity, poor health at baseline was found to be a significant precursor of unemployment in both genders. Conclusion: Those findings confirm the intrinsic role of poor health and of health-related behaviours as precursors of unemployment, with gender-specific patterns for the latter. Public policy prescriptions regarding employees’ protection from job insecurities should integrate appropriate accommodations of health limitations, and the personal factors underlying unfavourable work and health behaviours should be investigated, in order to thwart indirect selection phenomena.

BMC Public Health 2008; 8:159.

Abstract
BACKGROUND Having secure employment, in contrast to being unemployed, is regarded as an important determinant of health. Research and theories about the negative health consequences of unemployment indicated that transition from unemployment to a paid job could lead to improved health. The objective of this study was to test the hypothesis that obtaining permanent employment after being in an unstable labour market position protects mental health. METHODS A 14-year follow-up of all graduates from compulsory school in an industrial town in northern Sweden was performed at ages 16, 18, 21 and 30 years. Complete data on the cohort were collected for 1044 individuals with the aid of a comprehensive questionnaire. The response rate was 96.4%. The health measurement used in this study was the psychological symptoms analysed by multivariate logistic regression. Those who obtained permanent employment were the focus of the analysis. This group consisted of people who were in an unstable labour market position for a year or more between the ages of 25 and 29, and who had acquired a permanent job one year before and at the time of the investigation. RESULTS After controlling for gender as well as for an indicator of health-related selection, possible confounders and mediators, an association was found between the lower probability of psychological symptoms and obtaining permanent employment (OR = 0.35, 95% CI 0.19-0.63) as well as having permanent employment (OR = 0.22, 95% CI 0.10-0.51). CONCLUSION Our findings suggest that transition from an unstable labour market position to permanent employment could be health-promoting, even after controlling for possible confounders and mediators, as well as for an indicator of health-related selection. However, as there are few studies in the field, there is a need for more longitudinal studies in order to further analyse the relationship and to examine possible explanations. The policy implication of our study is that the transformation of unstable labour market positions into permanent employment could contribute to better public health.

Abstract
This article assesses the effects of comprehensive tobacco control policies on diverse subpopulations of girls and women who are at increased vulnerability to tobacco use because of disadvantage. The authors report on a recent assessment of experimental literature examining tobacco taxation; smoking location restrictions in public and private spaces; and sales restrictions. A comprehensive search was undertaken to identify relevant studies and evaluation reports. Gender based and diversity analyses were performed to identify pertinent sex differences and gender influences that would affect the application and impact of the policy. Finally, the results were contextualised within the wider literature on women's tobacco use and women's health. The authors consider not only the intended policy effects, but also explicitly examine the gendered and/or unintended consequences of these policies on other aspects of girls and women's health and wellbeing. A framework for developing gender sensitive tobacco programmes and policies for low income girls and women is provided.
