To analyze the relationship between engagement in sports in early life and bone variables among adults of both sexes.
The sample was composed of 225 men and women. Demographic data were collected, and dual-energy X-ray absorptiometry was used to assess bone mineral density, bone mineral content, and lean soft tissue. Sports participation in early life was assessed by an interview including childhood and adolescence. Consumption of tobacco and alcohol was also assessed by interview and the habitual physical activity level by a pedometer.
Inactive men had bone mineral content around 11% lower than active men in childhood or adolescence, whereas for women, this difference represented around 14%. Active men had 74% less fat mass than inactive men in early life, and the difference was 67% for women. Early sports participation explained the differences in whole-body bone mineral content (16.8%, P-value = .005) and bone mineral density (8.8%, P-value = .015), as well as bone mineral density in lower limbs (18.9%, P-value = .001) among women.
Adults engaged in sports in early life have higher bone mass than their inactive peers, especially women.
分析一生中早期参与运动与两性成人群体骨骼变量之间的关系。
该样本由 225 名男性和女性组成。收集了人口统计学数据，并使用双能 X 射线吸收法评估了骨矿物质密度、骨矿物质含量和瘦软组织。通过访谈评估了一生中早期的运动参与情况，包括儿童期和青少年期。通过访谈评估了烟草和酒精的消费情况，并通过计步器评估了习惯性体力活动水平。
不活跃的男性在儿童或青少年时期的骨矿物质含量比活跃的男性低约 11%，而女性的这一差异约为 14%。活跃的男性在早期的脂肪量比不活跃的男性少 74%，而女性的差异为 67%。早期运动参与解释了女性全身体骨矿物质含量（16.8%，P 值=0.005）和骨矿物质密度（8.8%，P 值=0.015）以及下肢骨矿物质密度（18.9%，P 值=0.001）差异的原因。
一生中早期参与运动的成年人比不活跃的同龄人具有更高的骨量，尤其是女性。
