妊娠意愿与孕早期体力活动关系的研究

The relationship between pregnancy intention and physical activityin the first trimester

目的探讨孕妇妊娠意愿与孕早期体力活动的关系。方法选取2015年6月至2016年6月在马鞍山市妇幼保健院早孕建卡的2122名孕早期妇女为研究对象,调查妊娠意愿等相关信息,并采用丹麦的自填式体力活动问卷了解孕早期体力活动状况;将每日中度以上体力活动达0.5h者评定为体力活动达标;分析不同妊娠意愿与孕早期体力活动状况的关联性。结果孕妇孕早期体力活动水平较低,体力活动类型主要为睡眠和静坐类型,体力活动达标者745人,仅占35.1%。完全意外怀孕、顺其自然怀孕和有充分思想准备怀孕者孕早期体力活动的达标率分别为39.7%、36.1%和31.4%,达标率依次降低,组间差异具有统计学意义(χ^2=7.096,P<0.05)。多因素分析显示,顺其自然怀孕(OR=0.756,95%CI=0.614~0.931,P<0.01)和完全意外怀孕(OR=0.591,95%CI=0.438~0.796,P<0.001)妊娠者孕早期体力活动不足风险低于有充分思想准备者。结论有充分思想准备怀孕的妇女较顺其自然怀孕和完全意外怀孕者体力活动不足问题更为明显。

Objective To explore the relationship between pregnancy intention and physical activity in the first trimester.Methods From June 2015to June 2016,2122first-trimester pregnant women enrolled in Ma'anshan Maternal and Child Health Hospital were selected as subjects,and their pregnancy intention and other relevant information were investigated.The Danish Self-administered Physical Activity Questionnaire was used to evaluate their physical activity during the first trimester.It was assessed as up to standard if the time of moderate-to-vigorous intensity physical activity was at least half an hour a day.And then the correlation between different pregnancy intention and physical activity in the first trimester was analyzed.Results The level of physical activity of pregnant women during the first trimester was low,and sleep and meditation were the main physical activity types.A total of 745 pregnant women met the standard,accounting for only 35.1%.The attainment rates of physical activity in women with unintentional pregnancy,natural pregnancy and intentional pregnancy were 39.7%,36.1%and 31.4%,respectively,the difference among the three groups was statistically significant(χ^2=7.096,P<0.05).Multivariate analysis showed that women with natural pregnancy(OR=0.756,95%CI:0.614-0.931,P<0.01)and unintentional pregnancy(OR=0.591,95%CI:0.438-0.796,P<0.001)had lower risk of insufficient physical activity during the first trimester than those who were well intentional.Conclusion The problem of insufficient physical activity during the first trimester is more serious in women with intentional pregnancy than that in women with naturally or unintentional pregnancy.
