Sažetak
Background: The proportion of heredity and environmental factors which influence the bone density is not precisely established. We analyzed the lifestyle predictors of bone density in adopted children and compared them to biological children. Methods: The study comprised 18 adopted children, aged 14.0 (4.1) years with their non-biological parents and the group of 17 children with their biological parents. Bone mineral density (BMD ; g/cm2) was measured at the lumbar spine, total femur and distal radius. Nutritional intake was assessed by food frequency questionnaire. Information on smoking and physical activity was obtained by a questionnaire. Results: Intake of all nutrients corrected for energy intake and the lifestyle characteristics, with exception of the sleeping, were similar in biological children and their parents. Adopted children had significantly different energy, protein and calcium intake and physical activity compared to their parents. In the regression model, significant negative relationship was found between adopted children′s and parents′ BMD z score at the spine and total femur, while significant positive relationship was found between biological children and parents′ BMD z score at all measure sites. The greatest proportion of total variance of BMD in adopted children was accounted for by calcium intake, while in biological children total variance of BMD was accounted for mostly by parents′ BMD. Conclusions: Some lifestyle characteristics and nutrient intake differ more prominently between parents and children in adoptive than in biological families. The most important lifestyle predictor of bone density was the calcium intake.
