ABSTRACT. Objective:The purpose of this study was to test the structure and endorsement of drinking motives and their links to alcohol use among 11-to 19-year-olds from 13 European countries. Method: Confi rmatory factor analysis, latent growth curves, and multiple regression models were conducted, based on a sample of 33,813 alcohol-using students from Belgium, Denmark, Estonia, Finland, Hungary, Ireland, Italy, Poland, Portugal, Scotland, Slovakia, Switzerland, and Wales who completed the Drinking Motives Questionnaire Revised Short Form (DMQ-R SF). Results: The fi ndings confi rmed the hypothesized fourdimensional factor structure. Social motives for drinking were most frequently indicated, followed by enhancement, coping, and conformity motives, in that order, in all age groups in all countries except Finland. This rank order was clearest among older adolescents and those from northern European countries. The results confi rmed that, across countries, social motives were strongly positively related to drinking frequency, enhancement motives were strongly positively related to frequency of drunkenness, and conformity motives were negatively related to both alcohol outcomes. Against our expectations, social motives were more closely related to drunkenness than were coping motives, particularly among younger adolescents. Conclusions: The fi ndings reveal striking cross-cultural consistency. Health promotion efforts that are based on, or incorporate, drinking motives are likely to be applicable across Europe. As social motives were particularly closely linked to drunkenness among young adolescents, measures to impede the modeling of alcohol use and skills to resist peer pressure are particularly important in this age group.

Background: Parents have significant influence on behaviors and perceptions surrounding eating, body image and weight in adolescents. The aim of this study was to examine the prevalence of body weight dissatisfaction, difficulty in communication with the parents and the relationship between communication with parents and adolescents' dissatisfaction with their body weight (dieting or perceived need to diet).

In over half of the countries examined overweight prevalence did not change during 2002-2010. However, increasing overweight prevalence was noted in many Eastern European countries over this time period. Overweight prevalence remained high in several countries in Europe and North America. These patterns call for continued research in youth overweight and highlight the need to understand cross-national differences by examining macro-level indicators. Such research should feed into developing sound translations and practices to prevent and reduce overweight in youth.

BackgroundLow to moderate agreement between self-reported and directly measured anthropometry is shown in studies for adults and children. However, this issue needs further evaluation during puberty, a period marked by several transitions. We examined the correspondence of BMI status based on self-reported versus measured anthropometric data among Estonian adolescents with a specific focus on gender and age differences.MethodsSelf-reported height and weight were determined in a national representative sample of Estonian schoolchildren collected within the framework of the HBSC (health behaviour of school-aged children) survey. Self-reported and directly measured height and weight were collected from 3379 students (1071 aged 11, 1133 aged 13 and 1175 aged 15 years). The standardized HBSC questionnaire was used for collecting self-reported data; direct anthropometric measures were taken after the HBSC questionnaires were completed. The accuracy of the self-reported values by age and gender groups were determined by comparing mean differences, Bland–Altman plots with limits of agreement, Kappa statistics, and by estimation of the sensitivity and positive predictive value for detecting overweight.ResultsMean self-reported weight, height and body mass index (BMI) values were significantly lower than corresponding values obtained using direct measurements. Mean differences between self-reported and directly measured weight, height and BMI were largest among 11-year-olds and smallest among students aged 15 years. Underestimation of overweight prevalence (includes obese) showed a graded trend which decreased in older age groups; the difference was greater among girls than boys in all age groups. The mean underestimation of overweight prevalence based on self-reported anthropometry was 3.6 percentage points. The positive predictive value was 72.3 % for boys and 63.4 % for girls.ConclusionA distinct age-related pattern in underestimation of weight, height and prevalence of overweight was found; the bias decreased with increasing age. The mean underestimation of overweight prevalence based on self-reports was small, 3.6 %. Self-reported height and weight remain the method of choice in large surveys for practical and logistical reasons.Electronic supplementary materialThe online version of this article (doi:10.1186/s13104-015-1587-9) contains supplementary material, which is available to authorized users.
