Childhood and adolescence are critical periods of bone mineral content (BMC) accrual that may have long-term consequences for osteoporosis in adulthood. Calcium intake in the diet and adequate physical activity are of maximum relevance in child developement. However, the relative effects of physical activity and calcium in the diet on BMC accrual during the process of pubertal development in childhood remains unclear.
The purpose of this Nebraska study was to determine the effects of calcium intake in the diet self-Reported Physical Activity and the Los bone accumulations during the Five Stages of pubertal development in a large cohort of Diverse Children and Adolescents North American Support weight. Bone mineral density in the Study of Childhood Longitudinal Study BE A mixed 7393 Observations on 1,743 subjects.
Annually, it was measured for DXA BMC, physical activity and calcium intake questionnaire, and the pubertal development (Tanner stage) Examination. They used mixed-effects regression models to assess the activity paragraph calcium intake and physical effects on BMC accrual at each Tanner stage.
It was found that physical activity self-reports of weight contributed significantly to a mayor devengamiento BMC in both sexes and racial subgroups (black and white). In Los black men there, the magnitude of the effect on activity of total body BMC accumulations vary between Tanner Stages fit after paragraph calcium intake; The Difference Between Kids Mayor of high and low activity was greater Managers Tanner Stage 3 intake of calcium had significant effect on bone accrual in girls only race not black. This effect was not significantly different between Tanner stages.
These results give no support for differential effects of physical activity and calcium intake on bone mass accrual according to the stage of maturation. The longitudinal study showed significant effects of weight that takes physical activity to bone accumulations during all developmental stages of puberty.
