| 目的 探讨山东省青岛和浙江省丽水地区双生子人群体育活动和静坐行为的遗传度。方法 使用两地区2004 年随访的有卵型信息的双生子人群（共568 对，其中青岛242 对，丽水326 对）横断面调查资料，通过问卷调查得到体育活动和静坐行为信息。采用基于双生子的方差组分分析方法计算双生子表型的遗传度。结果 同卵双生子有367 对，异卵双生子有201 对，双生子中男性571 人，女性565 人。同卵双生子年龄为（41.14±10.11）岁，异卵双生子年龄为（41.23±9.89）岁。青岛和丽水地区＜40 岁人群的体育活动遗传度为78%（35%～96%）、59%（0～94%），≥40 岁人群体育活动不受遗传影响。青岛和丽水地区静坐行为遗传度分别为68%（59%～75%）、32%（7%～62%）。结论 青岛和丽水地区人群静坐行为水平受遗传影响，且遗传因素在20～40 岁人群的体育活动水平中有着重要作用。 |

| Objective To investigate both genetic and environmental influences on the exercise participation and sedentary behavior in Qingdao，Shandong province and 326 in Lishui， Zhejiang province. Methods 568 twin pairs，including 242 in Qingdao and 326 in Lishui，were studied. Exercise participation was measured by two questions on the frequency and intensity and then divided into two groups. Sedentary behavior was measured by one question as‘how long do you spend on sitting every day’. Variance component models based on twins was used to estimate the genetic and environmental factors on these traits. Results The average age in monozygotic twins was（41.14±10.11）while in dizygotic twins it was（41.23±9.89）. Genetic factors accounted 78% （35%-96%）and 59%（0-94%）for exercise participation variance in Qingdao and Lishui in people aged between 20 and 40. However，there were no heritability noticed on physical activity in people older than 40 years of age. Rates of heritability on sedentary behavior in Qingdao and Lishui were 68% （59%-75%）and 32%（7%-62%），respectively. Conclusion Results from the study suggested that sedentary behavior in Chinese people was influenced by genetic factors，which could also explain much of the exercise participation variance in people aged between 20 and 40. |
