To investigate the relationship between bone mineral density (BMD), age, sex, anthropometric measurements, dietary calcium intake and daily physical activity, in prepubertal children with distal forearm fracture (DFF). 160 children (80 males, 80 females) 3-10 years of age with DFF; control group of 160 children (age-sex matched) were studied. Age, sex, weight, height, tricipital skin fold thickness (TS), body mass index, daily calcium intake, and level of physical activity (extra-school physical exercise: low 1hour/day) registered. BMD assessed by peripheral DXA densitometer. Most fractures were caused by mild-moderate precipitating trauma by accidental fall (85.6%), with radius fracture in most cases (87.5%). BMI was higher in patients (19.14 kg/m(2)+/-3.50 vs. 17.46 kg/m(2)+/-2.67; p0.05). Physical activity was lower in study group (extra-school physical activity >1h: 21.25% vs. 46.87%; p0.05). BMD was lower in fractured children (0.2591 g/cm(2)+/-0.0413 vs. 0.2801 g/cm(2)+/-0.0300; p
