Health and Social Determinants Among Boys and Girls in Sweden : Focusing on Parental Background
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The majority of Swedish boys and girls have good psychosomatic health. Despite that the risk of mental health problems such as nervousness, feeling low and sleeping difficulties has increased steadily in recent decades. Moreover, previous surveys on health and well-being indicate that boys and girls of foreign extraction in Sweden are at increased risk of ill health compared to boys and girls of Swedish background. The main aim of this thesis was to analyse health and social determinants among boys and girls of foreign extraction in Sweden. The factors explored in papers I–IV include parental background, family affluence and gender and their associations with subjective health complaints, psychosomatic problems or health risk behaviours. Other included risk factors for ill health were involvement in bullying, low participation and discrimination at school. This thesis takes an intersectional perspective, with ambitions to be able to emphasize the interplay between different power relations (i.e. gender, social class and parental background). Two sets of cross-sectional data were used. Three papers were based on the Swedish part of the World Health Organization’s Health Behaviour in School-Aged Children. The sample consisted of 11,972 children (boys n = 6054; girls n = 5918) in grades five, seven and nine from the measurement years 1997/98, 2001/02 and 2005/06. The response rate varied between 85 and 90%. About one fifth of the included children were of foreign extraction. For the fourth paper regional data from Northern Sweden were used. Boys (n = 729) and girls (n = 798) in grades six to nine answered a questionnaire in 2011 and the response rate was 80%. About 14% of the included children were of foreign extraction. Statistical methods used were chi-square test, correlation analyses, logistic regression analyses, cluster analyses and test of mediating factor. The results showed that girls of foreign background were at increased risk of subjective health complaints (SHC) and boys of mixed background were at increased risk of psychosomatic problems (PSP). Increased risk of allocation to the cluster profile of multiple risk behaviour was shown in boys and girls of mixed background, in girls of foreign background and in girls of low family affluence. Increased risk of allocation to the cluster profile of inadequate tooth brushing was shown in boys and girls of foreign background and in girls of low family affluence. General risk factors for increased risk of ill health for boys and girls in Sweden were: any form of bullying involvement, low family affluence, low participation and discrimination at school, of which the latter also was a mediating factor for ill health. Living with a single parent was a risk factor for ill health among girls. The results can function as a basis for developing health promotion programmes at schools that focus on social consequences of foreign extraction, family affluence, participation as well as health risk behaviours and gender.

- This study aimed to analyze how bullying involvement is associated with the distribution of parental background and with subjective health complaints (SHC) among Swedish boys and girls. Data were collected from the World Health Organization, Health Behavior in School-aged Children (WHO/HBSC) survey, measurement years 1997/1998, 2001/2002 and 2005/2006. A total of 11,972 boys (50.6 %) and girls (49.4 %) in grades five, seven and nine participated in the study. The adolescents were categorized in subgroups according to parental background: Swedish (80.1 %), mixed (10.5 %) and foreign(9.7 %). Multivariate logistic regressions were used to estimate remaining risk of SHC in the categories of bullying involvement. The frequencies of bullying involvement once or more were: none involved (74.8 %), victims (10.6 %), bullies (10.3 %) and bully/victims (4.4 %). Six out of ten involved in bullying were boys. Boys of foreign background were more involved as bullies compared to boys of mixed or Swedish background. Girls of foreign background were more involved in all three categories of bullying than girls of mixed or Swedish background. Increased risk of SHC was estimated among all adolescents involved in bullying, with highest OR in the category of bully/victims, OR 3.95 (CI 3.13–4.97) for the boys and OR 4.51 (CI 4.51–6.40) for the girls. The multivariate models were stable even after adjustment for socio-demographics. There are some associations between bullying involvement and parental background. Regardless of parental background, family affluence, family structure and gender, all adolescents involved in bullying are at increased risk of SHC.

- Background: Negative impact on health from school disturbance due to asymmetric power relations such as discrimination and offensive treatment are frequent problems among students. This study sought to analyze associations between occurrence of discrimination at school, participation and psychosomatic problems. Methods: Pupils in grades 6–9 in ten schools in a northern Swedish municipality participated in the study. The frequency of discrimination at school was measured by six items: sex; culture or ethnicity; disability; religion beliefs; sexual preferences; and any other form of discrimination. The Social and Civic Objectives Scale (SCOS) was used for an estimation of the level of participation. The pupils’ health was measured by the PsychoSomatic Problem (PSP) scale. Multivariate logistic regression models were used for estimation of increased risk of PSP. The formula Z=d/s (d)was used to test mediation. Results: Two thirds of the boys and three fourths of the girls reported occurrences of discrimination at schools (p = 0.001). Discrimination was a mediating factor between participation and PSP among boys and girls as the mediating formula Z=d/s (d) was > + 2 SD, –2.59 for boys and –39.27 for girls. Independent of each other, low participation and discrimination were associated with increased risk of PSP. Conclusion: Discrimination was a mediating factor between participation and PSP. The mediating effectwas stronger in girls than in boys. There is a need for school health promotion programsfocusing on participation in terms of democratic processes, communication and cooperation in the classroom.

- Aim: To analyse how health risk behaviours (HRB) are clustered and associated with parental background and family wealth among Swedish boys and girls.Methods: Data were collected from Health Behaviour in School-aged Children (HBSC),a global cross-sectional survey for 1997/98, 2001/02, and 2005/06. A total of 11,972 boys and girls in grades 5, 7, and 9 participated in the study. The pupils were categorised in subgroups according to parental background: Swedish (80.0%), mixed (10.6%), and foreign (9.4%). Cluster analyses were used to identify HRB profiles. Multinomial logistic regression analysis was used to estimate associations between cluster allocation, parental background, and family affluence.Results: In total 11,232 pupils were identified and allocated to five cluster profiles, half of them in the cluster profile of low-risk behaviour. The most disadvantaged cluster was multiple HRB, which was characterised by high prevalence of smoking, drunkenness, low physical activity, and high soft-drink consumption. The cluster profile of multiple HRB was associated with both mixed background and foreign background in girls and with mixed background in boys.. The cluster profile of inadequate tooth brushing was associated with foreign background in both boys and girls. The cluster profiles of multiple HRB and inadequate tooth brushing were associated with low family affluence in girls.Conclusions: The cluster profiles of multiple HRB and inadequate tooth brushing were associated with parental foreign extraction in boys and girls and with low family affluence in girls. Prevention programmes based on identified clusters of HRB, including consideration of impact of socio-demographic indicators, are needed.

- 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. © 2011 Swiss School of Public Health.

Comparison of alternative versions of the job demand-control scales in 17 European cohort studies : the IPD-Work consortium
- 2012
-
Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 12, s. 62-

Tidskriftsartikel (refereegranskat)abstract
- Background: Job strain (i.e., high job demands combined with low job control) is a frequently used indicator of harmful work stress, but studies have often used partial versions of the complete multi-item job demands and control scales. Understanding whether the different instruments assess the same underlying concepts has crucial implications for the interpretation of findings across studies, harmonisation of multi-cohort data for pooled analyses, and design of future studies. As part of the 'IPD-Work' (Individual-participant-data meta-analysis in working populations) consortium, we compared different versions of the demands and control scales available in 17 European cohort studies. Methods: Six of the 17 studies had information on the complete scales and 11 on partial scales. Here, we analyse individual level data from 70 751 participants of the studies which had complete scales (5 demand items, 6 job control items). Results: We found high Pearson correlation coefficients between complete scales of job demands and control relative to scales with at least three items (r > 0.90) and for partial scales with two items only (r = 0.76-0.88). In comparison with scores from the complete scales, the agreement between job strain definitions was very good when only one item was missing in either the demands or the control scale (kappa > 0.80); good for job strain assessed with three demand items and all six control items (kappa > 0.68) and moderate to good when items were missing from both scales (kappa = 0.54-0.76). The sensitivity was > 0.80 when only one item was missing from either scale, decreasing when several items were missing in one or both job strain subscales. Conclusions: Partial job demand and job control scales with at least half of the items of the complete scales, and job strain indices based on one complete and one partial scale, seemed to assess the same underlying concepts as the complete survey instruments.

Forskningsöversikt (refereegranskat)abstract
- Unfavorable work characteristics, such as low job control and too high or too low job demands, have been suggested to increase the likelihood of physical inactivity during leisure time, but this has not been verified in large-scale studies. The authors combined individual-level data from 14 European cohort studies (baseline years from 19851988 to 20062008) to examine the association between unfavorable work characteristics and leisure-time physical inactivity in a total of 170,162 employees (50 women; mean age, 43.5 years). Of these employees, 56,735 were reexamined after 29 years. In cross-sectional analyses, the odds for physical inactivity were 26 higher (odds ratio 1.26, 95 confidence interval: 1.15, 1.38) for employees with high-strain jobs (low control/high demands) and 21 higher (odds ratio 1.21, 95 confidence interval: 1.11, 1.31) for those with passive jobs (low control/low demands) compared with employees in low-strain jobs (high control/low demands). In prospective analyses restricted to physically active participants, the odds of becoming physically inactive during follow-up were 21 and 20 higher for those with high-strain (odds ratio 1.21, 95 confidence interval: 1.11, 1.32) and passive (odds ratio 1.20, 95 confidence interval: 1.11, 1.30) jobs at baseline. These data suggest that unfavorable work characteristics may have a spillover effect on leisure-time physical activity.

Tidskriftsartikel (refereegranskat)abstract
- Background: The relationship between work-related stress and alcohol intake is uncertain. In order to add to the thus far inconsistent evidence from relatively small studies, we conducted individual-participant meta-analyses of the association between work-related stress (operationalised as self-reported job strain) and alcohol intake. Methodology and Principal Findings: We analysed cross-sectional data from 12 European studies (n = 142 140) and longitudinal data from four studies (n = 48 646). Job strain and alcohol intake were self-reported. Job strain was analysed as a binary variable (strain vs. no strain). Alcohol intake was harmonised into the following categories: none, moderate (women: 1-14, men: 1-21 drinks/week), intermediate (women: 15-20, men: 22-27 drinks/week) and heavy (women: > 20, men: > 27 drinks/week). Cross-sectional associations were modelled using logistic regression and the results pooled in random effects meta-analyses. Longitudinal associations were examined using mixed effects logistic and modified Poisson regression. Compared to moderate drinkers, non-drinkers and (random effects odds ratio (OR): 1.10, 95% CI: 1.05, 1.14) and heavy drinkers (OR: 1.12, 95% CI: 1.00, 1.26) had higher odds of job strain. Intermediate drinkers, on the other hand, had lower odds of job strain (OR: 0.92, 95% CI: 0.86, 0.99). We found no clear evidence for longitudinal associations between job strain and alcohol intake. Conclusions: Our findings suggest that compared to moderate drinkers, non-drinkers and heavy drinkers are more likely and intermediate drinkers less likely to report work-related stress.

Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: Many clinicians, patients and patient advocacy groups believe stress to have a causal role in inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis. However, this is not corroborated by clear epidemiological research evidence. We investigated the association between work-related stress and incident Crohn's disease and ulcerative colitis using individual-level data from 95 000 European adults. Methods: We conducted individual-participant data meta-analyses in a set of pooled data from 11 prospective European studies. All studies are a part of the IPD-Work Consortium. Work-related psychosocial stress was operationalised as job strain (a combination of high demands and low control at work) and was self-reported at baseline. Crohn's disease and ulcerative colitis were ascertained from national hospitalisation and drug reimbursement registers. The associations between job strain and inflammatory bowel disease outcomes were modelled using Cox proportional hazards regression. The study-specific results were combined in random effects meta-analyses. Results: Of the 95 379 participants who were free of inflammatory bowel disease at baseline, 111 men and women developed Crohn's disease and 414 developed ulcerative colitis during follow-up. Job strain at baseline was not associated with incident Crohn's disease (multivariable-adjusted random effects hazard ratio: 0.83, 95% confidence interval: 0.48, 1.43) or ulcerative colitis (hazard ratio: 1.06, 95% CI: 0.76, 1.48). There was negligible heterogeneity among the study-specific associations. Conclusions: Our findings suggest that job strain, an indicator of work-related stress, is not a major risk factor for Crohn's disease or ulcerative colitis.

- BackgroundMany patients and healthcare professionals believe that work-related psychosocial stress, such as job strain, can make asthma worse, but this is not corroborated by empirical evidence. We investigated the associations between job strain and the incidence of severe asthma exacerbations in working-age European men and women. MethodsWe analysed individual-level data, collected between 1985 and 2010, from 102 175 working-age men and women in 11 prospective European studies. Job strain (a combination of high demands and low control at work) was self-reported at baseline. Incident severe asthma exacerbations were ascertained from national hospitalization and death registries. Associations between job strain and asthma exacerbations were modelled using Cox regression and the study-specific findings combined using random-effects meta-analyses. ResultsDuring a median follow-up of 10years, 1 109 individuals experienced a severe asthma exacerbation (430 with asthma as the primary diagnostic code). In the age- and sex-adjusted analyses, job strain was associated with an increased risk of severe asthma exacerbations defined using the primary diagnostic code (hazard ratio, HR: 1.27, 95% confidence interval, CI: 1.00, 1.61). This association attenuated towards the null after adjustment for potential confounders (HR: 1.22, 95% CI: 0.96, 1.55). No association was observed in the analyses with asthma defined using any diagnostic code (HR: 1.01, 95% CI: 0.86, 1.19). ConclusionsOur findings suggest that job strain is probably not an important risk factor for severe asthma exacerbations leading to hospitalization or death.
