Sociodemographic, ethnic and dietary factors associated with childhood obesity in Thessaloniki, Northern Greece
Tóm tắt
OBJECTIVE: To investigate sociodemographic, ethnic and dietary factors associated with the development of childhood obesity. DESIGN: 276 children, aged 8–12 years, randomly selected from seven schools in Thessaloniki, Northern Greece, participated in the study. 13% of the children were immigrants from neighboring Balkan countries and ex-Soviet Union countries. Data was collected using specific validated questionnaires. Anthropometric measurements, dietary intake and physical activity assessment were carried out for all children. RESULTS: 26.1% of the boys and 22.4% of the girls were overweight and a further 11.6% of boys and 10.9% of girls were obese. The overweight and obesity rate was significantly lower in immigrants (10% and 3.3%) compared to Greeks (25.8% and 12.7%), p=0.024. Obese children compared to their non-obese counterparts a) had parents who were obese at a higher percentage (p=0.001), b) reported that food preparation was carried out by their grandmother (p=0.006) and c) had less pocket money (p=0.004). Daily energy and carbohydrate intakes were significantly higher in immigrants compared to Greeks (1611±599Kcal vs 1363±471Kcal, p=0.036 and 188.31±70.63g vs 149.87±56.41g, p=0.001) and the same was true for exercise (6.38±7.22 h/w vs 4.14±4.18 h/w, p=0.049). CONCLUSIONS: In planning interventions for childhood obesity, sociodemographic factors in addition to food intake and physical activity patterns have to be considered.
