RESUMEN
Many young adolescents experiment with substance use which can have substantial health implications later in life. This study examined trends in substance use among Danish adolescents from 2002 to 2018, including exclusive and dual current use of alcohol and cigarettes. Data on 13- and 15-year-olds (N = 15,295) from five comparable cross-sectional Health Behavior in School-aged Children (HBSC) surveys were used. Cochran-Armitage test for trend assessed the development in substance use patterns over time. Overall, a decreasing trend in current use of alcohol and cigarettes was found among Danish adolescents during the 16-year study period: from 71.7% in 2002 to 51.6% in 2018. In 2018, most adolescents (41.8%) currently used alcohol exclusively, 8.6% had a dual current use of cigarettes and alcohol, and 1.3% smoked cigarettes exclusively. Trends in alcohol use differed according to age groups, while no gender-specific trends in substance use were found. Findings suggest that a significant prevention potential in adolescent substance use remains, and future initiatives may focus on dual use of substances as well as tailored efforts to specific subgroups in high risk of using substances.

AIMS: Existing quality of life questionnaires are either disease specific or generic in their assessment of themes which are perceived important to the quality of life in populations with disabilities. To be able to improve quality of life in a population with diverse disabilities there was a need for a cross-disability instrument. The Electronic Quality of Life (EQOL)-questionnaire was developed to meet this need. It is crucial that such an instrument is validated, easy to use, and interpret by, for example, clinicians and policy planners. This study aims to test the content validity of the EQOL questionnaire and to construct a user-friendly, cross-disability quality of life profile. METHODS: To further test the content validity of the EQOL-questionnaire, we conducted field test analyses on 318 individuals (aged 16-64) with self-reported disabilities. Comments on the questionnaire were scrutinised and sorted. A profile with six domains of quality of life was developed. Model fit was evaluated by confirmatory factor analysis and content validity was evaluated based on distributions. RESULTS: The EQOL-questionnaire was found to have an acceptable content validity and respondents from the field test found that it features important themes of quality of life. The confirmatory factor analysis estimated a satisfying model fit by the root-mean-squared error of approximation (0.06), whereas the comparative fit index and goodness of fit index indicated poorer model fit. Graphical charts, with colour categories for user-friendly interpretation, were constructed. CONCLUSION: By identifying themes reported as problematic, the EQOL-profile can be used to inform and target interventions aiming to improve quality of life in populations with diverse disabilities.

Aims: The aims of this study were: (a) to examine trends in daily emotional symptoms among 11- to 15-year-olds from 1991 to 2014 in Denmark, and (b) to examine trends in social inequality in daily emotional symptoms, that is, whether the differences in prevalence between adolescents with parents of varying occupational social class changed over time. Methods: We combined seven comparable cross-sectional Health Behaviour in School-aged Children surveys (N=31,169). Daily emotional symptoms were measured by the HBSC Symptom Check List and occupational social class (OSC) by students' reports about parents' occupation. We calculated absolute (per cent) differences in emotional symptoms between high and low OSC and relative differences by odds ratio for emotional symptoms by parents' OSC. Results: Eight per cent reported at least one daily emotional symptoms, with an increasing trend from 1991 to 2014 (p<0.001). The prevalence in high, middle and low OSC was 6.2%, 7.4% and 10.6% (p<0.0001). From 1991 to 2014, there was an increase in the prevalence of daily emotional symptoms in high (p<0.0001) and middle (p<0.0001) but not low OSC (p=0.4404). This resulted in a diminishing absolute social inequality in emotional symptoms. The statistical interaction between OSC and survey year was significant (p=0.0023) and suggests a diminishing relative social inequality in emotional symptoms from 1991 to 2014. Conclusions: There was an increasing prevalence of daily emotional symptoms from 1991 to 2014 and a diminishing social inequality in prevalence of daily emotional symptoms in terms of both absolute and relative social inequality.

BACKGROUND: Assessment of implementation is essential for the evaluation of school-based preventive activities. Interventions are more easily implemented in schools if detailed instructional manuals, lesson plans, and materials are provided; however, implementation may also be affected by other factors than the intervention itself-for example, school-level characteristics, such as principal support and organizational capacity. We examined school-level characteristics of schools in groups of high, medium, and low implementation of a smoking prevention intervention. METHODS: The X:IT study is a school-randomized trial testing a multicomponent intervention to prevent smoking among adolescents. Our data came from electronic questionnaires completed by school coordinators at 96.1% of participating intervention schools (N = 49) at first follow -up. RESULTS: Schools that implemented the X:IT intervention to a medium or high degree had higher levels of administrative leadership (77.3% and 83.3% vs 42.9%), school climate/organizational health (95.5% and 91.7% vs 66.7%), mission-policy alignment (90.9% and 100.0% vs 71.4%), personnel expertise (81.8% and 75.0% vs 46.7%), school culture (77.3% and 91.7% vs 53.3%), positive classroom climate (91.4% and 96.2% vs 82.9%) compared with low implementation schools. CONCLUSION: Our findings highlight the importance of considering the school context in future health prevention initiatives.

Children with cerebral palsy participate less in everyday activities than children in the general populations. During adolescence, rapid physical and psychological changes occur which may be more difficult for adolescents with impairments. Within the European SPARCLE project we measured frequency of participation of adolescents with cerebral palsy by administering the Questionnaire of Young People's Participation to 667 adolescents with cerebral palsy or their parents from nine European regions and to 4666 adolescents from the corresponding general populations. Domains and single items were analysed using respectively linear and logistic regression. Adolescents with cerebral palsy spent less time with friends and had less autonomy in their daily life than adolescents in the general populations. Adolescents with cerebral palsy participated much less in sport but played electronic games at least as often as adolescents in the general populations. Severity of motor and intellectual impairment had a significant impact on frequency of participation, the more severely impaired being more disadvantaged. Adolescents with an only slight impairment participated in some domains as often as adolescents in the general populations. Regional variation existed. For example adolescents with cerebral palsy in central Italy were most disadvantaged according to decisional autonomy, while adolescents with cerebral palsy in east Denmark and northern England played sports as often as their general populations. Participation is an important health outcome. Personal and environmental predictors of participation of adolescents with cerebral palsy need to be identified in order to design interventions directed to such predictors; and in order to inform the content of services.

OBJECTIVES: To use comparable data from many countries to examine 1) socio-economic inequality in multiple health complaints among adolescents, 2) whether the countries' absolute wealth and economic inequality was associated with symptom load among adolescents, and 3) whether the countries' absolute wealth and economic inequality explained part of the individual level socio-economic variation in health complaints. METHODS: The Health Behaviour in School-aged Children (HBSC) international study from 2005/06 provided data on 204,534 11-, 13- and 15-year old students from nationally random samples of schools in 37 countries in Europe and North America. The outcome measure was prevalence of at least two daily health complaints, measured by the HBSC Symptom Check List. We included three independent variables at the individual level (sex, age group, family affluence measured by the Family Affluence Scale FAS) and two macro level measures on the country's economic situation: wealth measured by Gross National Product (GNP) and distribution of income measured by the Gini coefficient. RESULTS: There was a significant socio-economic variation in health complaints in 31 of the 37 countries. The overall OR (95 % CI) for 2+ daily health complaints for all countries was 1.31 (1.27-1.36) in the medium versus high FAS group and 2.07 (2.00-2.14) in the low versus high FAS group. This socio-economic gradient in health complaints attenuated somewhat in the multilevel models which included macro level data. There was no association between GNP and health complaints. The OR for high symptom load was 1.35 (1.08-1.69) per 10 % increase in Gini coefficient. The socio-economic gradient in health complaints at the individual level was somewhat attenuated in the multilevel models which included macro level data. CONCLUSIONS: There was a significant association between low FAS and high level of health complaints in 30 of 37 countries. Health complaints increased significantly by increasing income inequality in the country.

BACKGROUND AND AIM: In most northern European countries adolescent smoking is most prevalent in lower social classes but there is little information about time trends in social inequality. This paper describes trends in social inequality in daily smoking among adolescents from 1991 to 2006 by both absolute social inequality (prevalence difference between low and high social class) and relative social inequality (prevalence ratio). METHODS: We analysed 15-year-olds from the Health Behaviour in School-aged Children (HBSC) study in Denmark in 1991, 1994, 1998, 2002 and 2006, total n = 6703. The surveys were comparable because of similar procedures for sampling, data collection, and measurements of smoking and parents' occupational social class. FINDINGS: From 1991 to 2006 the prevalence of daily smoking decreased from 15.9% to 10.9% among boys and from 20.1% to 10.6% among girls. The social inequality fluctuated over time and was different for boys and for girls. The prevalence difference between boys from low and high social class was 5.2% in 1991 and 9.3% in 2006, corresponding figures for girls were 4.8% and 7.0%. The prevalence ratio among boys was 1.38 (in 1991) and 2.19 (in 2006), among girls 1.28 and 1.95. CONCLUSIONS: Daily smoking was most prevalent among students from lower social classes and the level of inequality fluctuated over time. Conclusions on social inequality in adolescent smoking may appear differently when described by absolute and relative measures. The absolute and relative social inequality in adolescent smoking was higher in 2006 than in 1991.

BACKGROUND: The objective was to test whether an association between school connectedness and smoking exists among Danish school children, and if so, to examine whether parental smoking attitude and parental smoking behaviour influenced this association. METHODS: Data were collected by the Danish contribution to the cross-national study Health Behaviour in School-Aged Children (HBSC) 1998. Analyses were performed on questionnaire-based data from 1537 students at grade nine from a random sample of schools in Denmark. RESULTS: An independent inverse association was found between school connectedness and smoking among both boys and girls. Parents' attitude to their children's smoking significantly modified this association among boys. Among girls the modifying effect was less marked. Neither among boys nor girls did parental smoking behaviour significantly modify the association between school connectedness and smoking, although a modifying tendency was observed among girls. CONCLUSIONS: The smoking behaviour of Danish adolescents may be influenced by complicated interactions of varying sets of experienced smoking norms, and any research project or preventive programme focusing on the influence of school life on adolescent smoking behaviour needs to consider the family smoking norms. Additionally, the results stress the important role of gender by indicating that the smoking behaviour of girls may be more sensitive to restricting social influences than the smoking behaviour of boys.

AIMS: An analysis was undertaken to investigate social inequalities in health among old men and women in relation to five indicators of social position. METHODS: The study is based on a population-based cross-sectional survey among 748 75-year-old men and women, which was performed as clinical examinations and interviews in 1989 in Glostrup, a suburban area west of Copenhagen. Social position was measured by vocational education, occupation, social class, income, and housing tenure. Health was measured by number of chronic diseases, tiredness in relation to mobility, need of help in relation to mobility, oral health (number of teeth), and well-being (the CES-D Scale). The statistical analysis included bivariate contingency tables and logistic regression analyses. RESULTS: Two material wealth variables (income and tenure) were consistently related to nearly all health measures while the relationships between the other social position variables and health showed no consistent patterns. Multiple logistic regression analyses with tenure and income as independent variables and each of the health variables as dependent variables and control for education and occupation showed different patterns for men and women. In men the odds ratios of housing tenure on four health variables were strong and unaffected by education and occupation while in women the odds ratios of income on three health variables were strong and unaffected by education and occupation. CONCLUSION: This study demonstrates strong, consistent associations between variables of material wealth indicators and various measures of health among 75-year-old men and women.

AIMS: To quantify the correlation between male and female smoking prevalence in elementary school classes by group-level analysis. METHODS: This study was the Danish contribution to the cross-national study Health Behaviour in School-Aged Children (HBSC) 1998. Ninety school classes at grade nine (1,515 students) from a random sample of schools in Denmark took part. The proportion of male and female "at all" smokers and daily smokers in the school class was calculated. RESULTS: The mean "at all" smoking proportion in the school classes is 39% for girls and 32% for boys. The proportion of male and female smokers within school classes does not correlate. There is high variation in male and female smoking behaviour between school classes. CONCLUSIONS: The influence of social classroom environment on the processes causing smoking behaviour may be different for boys and girls. This paper illustrates that group-level analysis provides valuable new knowledge.

INTRODUCTION: The objective was to study the correlation between male and female smoking prevalence in elementary school classes at grade nine through group-level analysis. MATERIAL AND METHODS: Data was collected by the 1998 Danish contribution to the cross-national study Health Behaviour in School-Aged Children. A standardised questionnaire was applied. This study included ninety school classes at grade nine (1515 students) from a random sample of schools in Denmark. The outcome measure was the proportion of male and female smokers in the school classes. RESULTS: The proportion of male and female smokers within the school classes did not correlate. For both boys and girls there was a high variation in the proportion of smokers between the school classes. DISCUSSION: The smoking-related social processes that exist in the school classes probably operate in a sex-differentiated manner. The effect of the classroom environment on the students' smoking behaviour must be considered differently for boys and girls.
