目的:比较妇女产后1年内不同时点体力活动水平对其腰围、臀围、腰臀比和腰围身高比值的影响,探索妇女产后体格复原进程。方法:对合肥市某区妇幼保健院体检的645名妇女建立基线,在其产后42天和3、6、9、12个月调查体力活动情况及测量腰围、臀围,计算腰臀比(WHR)、腰围身高比(WHtR),采用四分位间距法对各时点不同体力活动水平妇女分为3个组进行比较。结果:产后3、9个月P25组较P25-75组的臀围值大,差异有统计学意义(P<0.05)。产后9个月P25组妇女较P25-75组、P75组妇女的腰围和WHR、WHtR值大,腰围异常值检出率高,差异有统计学意义(P<0.05);产后12个月P25组妇女较P75组妇女臀围、WHtR值大,差异有统计学意义(P<0.05)。结论:建议妇女在产后应进行适量的体力活动,以促进妇女产后体格复原,预防中心性肥胖发生发展,降低罹患相关疾病风险。
OBJECTIVE: To compare the effects of different levels of physical activity at different time points on the waistline, hip circumference, waist-to-hip ratio and waistline height ratio of women at post-natal period, and to explore the process of women’s post-natal physical rehabilitation. Methods: A total of 645 women undergoing physical examinations in a MCH hospital in Hefei City were enrolled in the study. Physical activity was measured at 42 days, 3,6,9,12 months postpartum and waist circumference and hip circumference were measured. WHR ) And waist circumference ratio (WHtR). The interquartile range method was used to compare the women with different physical activity levels at different time points. Results: The hip circumference of P25 group was significantly larger than that of P25-75 group at 3 and 9 months postpartum (P <0.05). At 9 months postpartum, women in P25 group had higher waist circumference, WHR and WHtR than those in P25-75 group and P75 group, with significant difference in waist circumference (P <0.05). P25 group Women than the P75 group of women hip circumference, WHtR value, the difference was statistically significant (P <0.05). Conclusion: It is recommended that women should take appropriate physical activity after delivery to promote post-partum physical rehabilitation, prevent the development of central obesity, and reduce the risk of developing related diseases.
