Sažetak
We wanted to evaluate a bone mineral density (BMD) in families with adopted children and to analyze possible similarities in BMD between adopted children and their non-biological parents. Thirteen children including two pairs of siblings, who were adopted by 10 parents, were recruited. The mean age of children was 14.4 ± 2.9 years and 49, 5 ± 4, 4 years for parents. Bone mineral density (BMD ; g/cm2) at the spine and total hip was determined by dual energy absorptiometry (DXA). Anthropometric measurements, assessment of calcium intake and physical activity were also determined. In both skeletal sites the BMD of parents was higher than that of their children (p < 0.001 in spine, p = 0.010 in total hip). There was no significant correlation in BMD between parents and children. Mean calcium intake was in accordance with the RDA (recommended daily allowance) in parents and children. Physical activity differed significantly according to sex (higher in males ; p < 0.0001). To determine what percentage of the total variation in child bone mineral density can be explained by predictor variables, we used the squared semi-partial correlation. The proportion of variance caused by environmental covariates (calcium intake and physical activity), after adjusting child BMD for age, height and weight was 14% for the spine and 17% for the total hip. We conclude that heredity had more influence on BMD than selected environmental factors. However, we believe that we may have underestimated the effect of other environmental factors known to be important for bone health.
