Objective The community of residence (ie, urban vs rural) is one of the known factors of influence on substance use and misuse (SUM). The aim of this study was to explore the community-specific prevalence of SUM and the associations that exist between scholastic, familial, sports and sociodemographic factors with SUM in adolescents from Bosnia and Herzegovina. Methods In this cross-sectional study, which was completed between November and December 2014, the participants were 957 adolescents (aged 17 to 18 years) from Bosnia and Herzegovina (485; 50.6% females). The independent variables were sociodemographic, academic, sport and familial factors. The dependent variables consisted of questions on cigarette smoking and alcohol consumption. We have calculated differences between groups of participants (gender, community), while the logistic regressions were applied to define associations between the independent and dependent variables. Results In the urban community, cigarette smoking is more prevalent in girls (OR=2.05; 95% CI 1.27 to 3.35), while harmful drinking is more prevalent in boys (OR=2.07; 95% CI 1.59 to 2.73). When data are weighted by gender and community, harmful drinking is more prevalent in urban boys (OR=1.97; 95% CI 1.31 to 2.95), cigarette smoking is more frequent in rural boys (OR=1.61; 95% CI 1.04 to 2.39), and urban girls misuse substances to a greater extent than rural girls (OR=1.70; 95% CI 1.16 to 2.51,OR=2.85; 95% CI 1.88 to 4.31,OR=2.78; 95% CI 1.67 to 4.61 for cigarette smoking, harmful drinking and simultaneous smoking-drinking, respectively). Academic failure is strongly associated with a higher likelihood of SUM. The associations between parental factors and SUM are more evident in urban youth. Sports factors are specifically correlated with SUM for urban girls. Conclusions Living in an urban environment should be considered as a higher risk factor for SUM in girls. Parental variables are more strongly associated with SUM among urban youth, most probably because of the higher parental involvement in children’ personal lives in urban communities (ie, college plans, for example). Specific indicators should be monitored in the prevention of SUM.

INTRODUCTION Childhood obesity is currently considered to be one of the most prevailing and challenging public health issues in industrialized countries and some developing countries, including the Republic of Srpska. OBJECTIVE Our objective was to determine macronutrients intake in collective diet of preschool children and to estimate the rate of obesity in this population. METHODS Samples of food intended for preschool children diet were collected in a preschool facility in the western region of the Republic of Srpska. In daily portions, the content of proteins, fats, carbohydrates, water and mineral matter were determined using standard methods. The body mass index was determined on the basis of anthropometric measurements. RESULTS An average daily meal contained 17.5 g of fats, 19.1 g of proteins and 101.5 g of carbohydrates. The energy value was 676 Kcal. The analysis of the data from the menu showed that the number of consumed servings of fruits, vegetables, legumes, milk and dairy products was less than one portion per day. However, the amount of consumed meat and meat products exceeded one portion per day. Out of the total number of children, 10.0% were undernourished, 16.7% were overweight and 13.3% were obese. CONCLUSION Daily portions in the preschool facility are not in accordance with the recommended dietary allowance for energy and carbohydrates intake, and the composition of meals is inadequate. Parents and caregivers should be encouraged to expose young children to a wide variety of fruit and vegetables, whole grains, low-fat dairy products, and to balance food intake with the requirements.

Background . Self-regulation is an important executive function responsible for the control of emotions, behaviors and inner processes. It is related to the academic success of the children as well as to their cognitive and social development. Children with intellectual disability are reported to have significant deficits in self-regulation skills. Objective. The goal of this study was to examine self-regulation skills in children with mild intellectual disability. The addi­tional goals were to examine self-regulation in relation to the child’s gender and to examine the relationship between age and self-regulation. Method . The sample for this study com­prised 42 children with mild intellectual disability, aged 7 to 15. There were 22 boys and 20 girls. Self- regulation was assessed with the Behavior Rating Inventory of Executive Function (BRIEF). Results . The results indicated that 10 children or 23.8% had clinically significant deficit in self-regulation skills. Self-regulation skills in this sample were significantly lower as com pared to the normative sample. Boys had better self-regulation skills than the girls in this sample. Self-regulation skills were impro­ving with age for this sample of participants. Conclusion . Given the fact that these skills can be improved, it is suggested that educa­tional institutions should give more attention to the development of executive functions at school age. Educational institu­tions should consider incorporating the training of executive functions into their curriculums.
