Socioeconomic inequalities in health among Swedish adolescents - adding the subjective perspective

Abstract Background Socioeconomic inequalities in adolescent health predict future inequalities in adult health. Subjective measures of socioeconomic status (SES) may contribute with an increased understanding of these inequalities. The aim of this study was to investigate socioeconomic health inequalities using both a subjective and an objective measure of SES among Swedish adolescents. Method Cross-sectional HBSC-data from 2002 to 2014 was used with a total sample of 23,088 adolescents aged 11–15 years. Three measures of self-rated health (dependent variables) were assessed: multiple health complaints, life satisfaction and health perception. SES was measured objectively by the Family Affluence Scale (FAS) and subjectively by “perceived family wealth” (independent variables). The trend for health inequalities was investigated descriptively with independent t-tests and the relationship between independent and dependent variables was investigated with multiple logistic regression analysis. Gender, age and survey year was considered as possible confounders. Results Subjective SES was more strongly related to health outcomes than the objective measure (FAS). Also, the relation between FAS and health was weakened and even reversed (for multiple health complaints) when subjective SES was tested simultaneously in regression models (FAS OR: 1.03, CI: 1.00;1.06 and subjective SES OR: 0.66, CI: 0.63;0.68). Conclusions The level of socioeconomic inequalities in adolescent health varied depending on which measure that was used to define SES. When focusing on adolescents, the subjective appraisals of SES is important to consider because they seem to provide a stronger tool for identifying inequalities in health for this group. This finding is important for policy makers to consider given the persistence of health inequalities in Sweden and other high-income countries

The supermembrane with central charges:(2+1)-D NCSYM, confinement and phase transition

The spectrum of the bosonic sector of the D=11 supermembrane with central charges is shown to be discrete and with finite multiplicities, hence containing a mass gap. The result extends to the exact theory our previous proof of the similar property for the SU(N) regularised model and strongly suggest discreteness of the spectrum for the complete Hamiltonian of the supermembrane with central charges. This theory is a quantum equivalent to a symplectic non-commutative super-Yang-Mills in 2+1 dimensions, where the space-like sector is a Riemann surface of positive genus. In this context, it is argued how the theory in 4D exhibits confinement in the N=1 supermembrane with central charges phase and how the theory enters in the quark-gluon plasma phase through the spontaneous breaking of the centre. This phase is interpreted in terms of the compactified supermembrane without central charges.Comment: 33 pages, Latex.

Social support from developmental contexts and adolescent substance use and well-being: a comparative study of Spain and Portugal

The aim of this study was to analyse the contribution of social support from family, friend and school (teacher and classmate) contexts in substance use (tobacco and alcohol use) and well-being (life satisfaction and health-related quality of life). Participants were 5,784 Portuguese and 22,610 Spanish adolescents aged 11 to 16 years, from the 2014 edition of the Health Behavior in School-aged Children (HBSC) study in Portugal and Spain. Results showed that for a higher life satisfaction, family ( p < .001, partial η 2 = .032), teacher ( p < .001, partial η 2 = .018) and classmate ( p < .001, partial η 2 = .031) support were important in Portugal, and family ( p < .001, partial η 2 = .056) and friend ( p < .001, partial η 2 = .015) support in Spain. Similarly, for a better health-related quality of life, all the social support variables were relevant in Portugal (family: p < .001, partial η 2 = .063; teacher: p < .001, partial η 2 = .032; classmate: p < .001, partial η 2 = .054; friend: p < .001, partial η 2 = .034) and in Spain (family: p < .001, partial η 2 = .054; teacher: p < .001, partial η 2 = .014; classmate: p < .001, partial η 2 = .018; friend: p < .001, partial η 2 = .040). In contrast, only family support ( p < .001, partial η 2 = .014) was relevant in Portugal for tobacco use. Therefore, social support was more relevant for adolescent well-being than for adolescent substance use, and the most relevant source of support was family support, in both Spain and Portugal

A new version of the HBSC Family Affluence Scale - FAS III: Scottish qualitative findings from the International FAS Development Study

A critical review of the Family Affluence Scale (FAS) concluded that FAS II was no longer discriminatory within very rich or very poor countries, where a very high or a very low proportion of children were categorised as high FAS or low FAS respectively (Currie et al. 2008). The review concluded that a new version of FAS - FAS III - should be developed to take into account current trends in family consumption patterns across the European region, the US and Canada. In 2012, the FAS Development and Validation Study was conducted in eight countries - Denmark, Greenland, Italy, Norway, Poland, Romania, Slovakia and Scotland. This paper describes the Scottish qualitative findings from this study. The Scottish qualitative fieldwork comprising cognitive interviews and focus groups sampled from 11, 13 and 15 year-old participants from 18 of the most- and least- economically deprived schools. These qualitative results were used to inform the final FAS III recommendations.Publisher PDFPeer reviewe

Self-efficacy and medicine use for headache among adolescents in Italy: results from the Italian HBSC 2010 study

This article aims first to investigate gender patterns in medicine use, and corresponding headache complaints, in Italian adolescents; second, to examine the association between self-efficacy and medicine use for headache. This study used data from 23,941 15-year-old students participating in the 2009/2010 Health Behaviour in School-aged Children (HBSC) Survey. Self-complete questionnaires devised by the HBSC international group were administered in classrooms. Logistic regression models (controlling demographics: age, gender, and FAS) were used to investigate the association between medicine use for the associated health complaint, and perceived self-efficacy. Overall, prevalence of students reporting medicine use for headache (at least once a month) was 40.1%. Medicine use was significantly more common among girls than among boys for that somatic symptom. The use of medicines was significantly associated with the frequency of the corresponding health complaint. Selfefficacy was associated with a lower use of medicine for headache just for the group with low frequency of headache. In conclusion, self-efficacy may reduce the tendency to use medicines when adolescents report infrequent headaches

Trends in high life satisfaction among adolescents in five Nordic countries 2002–2014

Life satisfaction is an important indicator when assessing positive mental health aspects in populations, including among adolescents. The aim of this study was to investigate trends over time in prevalence of high life satisfaction among adolescents from five Nordic countries: Denmark, Iceland, Finland, Norway and Sweden. We used data from four waves of the Health Behaviour in School-Aged Children study from 2002, 2006, 2010 and 2014 (n=109,847). HBSC is a school-based study examining social circumstances, health and health behaviour among 11-, 13- and 15-years olds every four years in many European and North American countries. The Cantril Ladder, an 11-step visual analogue scale, was used as the measure of life satisfaction, and was dichotomised into two groups: high life satisfaction (scoring 9 or 10 on the scale) and medium/low life satisfaction (scoring <9). Over the 12-year period studied, between 28.6 and 44.8% of adolescents in the five countries rated their life satisfaction as high. Relatively large changes in prevalence levels occurred at the country level over the period. Denmark and Finland showed a steady, significant decline in the prevalence of high life satisfaction over the years. Iceland showed the highest prevalence in 2010. Norway and Sweden showed similar development until 2010, followed by a clear increase for Norway and a sharp decline in adolescent high life satisfaction for Sweden up until 2014. In all countries, high life satisfaction was most prevalent in 11-year- olds and least prevalent in almost all surveys among 15-year-old girls.peerReviewe

Socioeconomic disparities in diet vary according to migration status among adolescents in Belgium

Little information concerning social disparities in adolescent dietary habits is currently available, especially regarding migration status. The aim of the present study was to estimate socioeconomic disparities in dietary habits of school adolescents from different migration backgrounds. In the 2014 cross-sectional Health Behavior in School-Aged Children survey in Belgium, food consumption was estimated using a self-administrated short food frequency questionnaire. In total, 19,172 school adolescents aged 10-19 years were included in analyses. Multilevel multiple binary and multinomial logistic regressions were performed, stratified by migration status (natives, 2nd- and 1st-generation immigrants). Overall, immigrants more frequently consumed both healthy and unhealthy foods. Indeed, 32.4% of 1st-generation immigrants, 26.5% of 2nd-generation immigrants, and 16.7% of natives consumed fish two days a week. Compared to those having a high family affluence scale (FAS), adolescents with a low FAS were more likely to consume chips and fries once a day (vs. <once a day: Natives aRRR = 1.39 (95%CI: 1.12-1.73); NS in immigrants). Immigrants at schools in Flanders were less likely than those in Brussels to consume sugar-sweetened beverages 2-6 days a week (vs. once a week: Natives aRRR = 1.86 (95%CI: 1.32-2.62); 2nd-generation immigrants aRRR = 1.52 (1.11-2.09); NS in 1st-generation immigrants). The migration gradient observed here underlines a process of acculturation. Narrower socioeconomic disparities in immigrant dietary habits compared with natives suggest that such habits are primarily defined by culture of origin. Nutrition interventions should thus include cultural components of dietary habits
