Poverty and other correlates of obesity and underweight among 7-year-olds from Croatia and Montenegro.

OBJECTIVES: This study aimed at investigating poverty and other correlates of childhood underweight and obesity in two urban regions with lower (Podgorica, Montenegro) and higher economic development (Osijek, Croatia). STUDY DESIGN: Comparative study. METHODS: A comparative study was conducted on 693 children (52% boys), aged 7 years old (224 from Podgorica and 469 from Osijek). Parents completed the study-specific questionnaire on relevant factors for children's nutritional status. We measured children's height and weight and calculated their body mass index (BMI). International Obesity Task Force cut-off values of BMI were used to assess children's nutritional status. Subjective social position was assessed by the Mac Arthur scale. RESULTS: There were more underweight children in Osijek compared with Podgorica, both among boys (5.5% vs. 1.6%) and girls (6.9% vs. 1.0%). Obesity was more frequent in Podgorica than Osijek, both among boys (11.3% vs. 5.9%) and girls (10.0% vs. 4.3%). However, poverty in two cities diminished observed differences in children's nutritional status. The odds for child underweight decreased by 12.2%, while the odds for obesity increased by 3.6% per each paternal BMI unit. The frequency of child obesity was lowered per each step higher on the Mac Arthur scale and with breastfeeding by 23.2% and 68.0%, respectively. CONCLUSIONS: We show that a higher economic development is related to less obese children but more underweight children. However, poverty seems to impact nutritionally all children equally, regardless of the regional economic development. Paternal and not maternal BMI is relevant for both extremes in children's nutritional status. Breastfeeding and higher social position independently protect from child obesity.

Hypertension and correlates among Montenegrin schoolchildren-a cross-sectional study.

OBJECTIVES: In one of the few national studies of children in a former Eastern bloc country emerging as a Western democracy and the first such study ever in Montenegro, this study establishes the prevalence and correlates of childhood hypertension (CH). STUDY DESIGN: A cross-sectional national study. METHODS: The study was conducted with 3254 children aged 7-13 years (50.3% male) from 39 elementary schools. We used a structured questionnaire to gather sociodemographic information as well as data on factors potentially related to CH. Children's nutritional status was assessed using the criteria of the International Obesity Task Force. Waist circumference was also measured. Blood pressure was measured in schools using an oscillometric monitor. CH was defined as an average systolic blood pressure and/or diastolic blood pressure greater than or equal to the 95th percentile for sex, age, and height. RESULTS: The prevalence of CH was 10.4% with no differences between boys and girls. Multiple regression revealed that the odds for child hypertension were lowered by 10% for each year of age. On the other hand, rural environment and child obesity raised the odds of hypertension by 38% and 68%, respectively. CONCLUSIONS: We found hypertension in one out of ten Montenegrin schoolchildren, with no gender differences. Obesity and rural areas may be unfriendly to children's blood pressure.
