Background: The aim of this study was to investigate physical activity and associated factors in women with gestational diabetes mellitus (GDM).
Methods: This cross-sectional study was performed on 2706 women as part of the Lifestyle INtervention for Diabetes prevention After pregnancy (LINDA-Brasil) study, recruited between 2012 and 2016 in Brazil. A structured questionnaire was used to assess physical activity. Descriptive and Poisson regression analyses were used to investigate physical activity and associated factors.
Results: Counseling regarding physical activity practices was reported by 47.4% and 34.3% of women before and after a diagnosis of GDM, respectively. During pregnancy, 26% of women were classified as inactive, 39.7% were classified as insufficiently active, and 34.3% were classified as active. Compared with prepregnancy, 63.1% of women reported a decrease in physical activity levels during pregnancy. The prevalence of being inactive during pregnancy was higher among women who did not live with a partner (P = 0.003), had a lower household income (P = 0.01), were employed (P < 0.001), and who had four or more children (P < 0.001).
Conclusion: Among Brazilian women with GDM, physical activity levels and practices were low, with most women reporting decreased physical activity during pregnancy. A low socioeconomic status was associated with lower physical activity. These findings indicate the need to reinforce the importance of physical activity in the management of GDM in Brazil.
摘要: 背景 这项研究的目的是在妊娠糖尿病(gestational diabetes Mellitus，GDM)妇女中调查体力活动与相关因素对糖尿病的影响。 方法 这项研究是妊娠后生活方式干预预防糖尿病研究(Lifestyle INtervention for Diabetes prevention After pregnancy [LINDA-Brasil] study)的一部分，2012至2016年间从巴西招募了2706名妇女进行了横断面研究。通过结构化问卷测量体力活动。采用了描述性与泊松回归分析方法，研究体力活动及其相关因素对糖尿病的影响。 结果 在诊断GDM之前及之后，分别有47.4%与34.3%的妇女接受了体力活动咨询。在妊娠期间，有26%的妇女被归类为不活动类别，39.7%被归类为活动不足，34.3%被归类为积极活动。与妊娠前相比，63.1%的妇女报告妊娠期间的体力活动水平下降。未与伴侣一起生活的妇女，其妊娠期间不活动的比例明显更高(P = 0.003)，并且她们的家庭收入也较低(P = 0.01)，是有工作的(P < 0.001)，而且她们有4个或者更多的小孩(P < 0.001)。 结论 在巴西GDM妇女中，体力活动水平与锻炼程度都较低，并且大部分妇女都报告妊娠期间的体力活动水平下降。社会经济地位较低与体力活动较少有关。这些研究结果表明在巴西GDM的管理中，需要强调体力活动的重要性。.
