Heritability of body mass index and physical activity in Ukrainian adolescents

The article analyzed the lifestyle and physical development of Ukrainian adolescents their parents estimated familial aggregation heritability body mass index activity. 408 nuclear families were examined (1216 people with complete information). Anthropometric measures such as weight, height measured following standardized procedures WHO. Questionnaires used to estimate levels method genetic epidemiology research was explore (h2) family (ρ). Analysis performed using software product S.A.G.E. study showed that 12.0±1.6% children overweight or obese, 6.4±1.2% underweight 81.6±1.9% normal weight. It found among aged 12-15 years, 17.5±3.1% boys 32.7±2.9% girls physically inactive. Body values higher than 25.0 kg/m2 in 34.3±2.4 mothers 70.6±2.3% fathers. proportion inactive persons 45.7±2.5% 51.1±2.7% Heritability significant for both (h2 =0.41±0.09; p<0.001) activity =0.23±0.07; p<0.001). Significant correlations obtained between parents-offspring (ρ=0.20±0.04; (ρ=0.25±0.03; mother-son mother-daughter pairs father-son father-daughter pairs. highest is (ρ = 0.29 ± 0.06; p <0.001), lowest (ρ=0.19±0.08; p<0.05) by index. As inactivity increase risk non-communicable diseases development, data should be taken into account while planning preventive measures.
