Ångest efter graviditet : Vilken betydelse har Body Mass Index, muskelmassa och fysisk aktivitet?

Sammanfattning: Background: The prevalence of anxiety postpartum is high. Physical activity has shown positive effects for depressive symptoms and anxiety in pregnant women. The risk of anxiety postpartum can increase with a high and low Body Mass Index (BMI), no studies have been found to investigate the correlation between muscle mass and anxiety. Aim: To investigate the correlation between level of anxiety, BMI and proportion of muscle mass postpartum and see if there were any differences in level of self-reported anxiety between two independents groups: those who reported regular exercise and those who didn’t report regular exercise during pregnancy. Method: A quantitative correlative and comparative cross-sectional study. Data was collected using Beck Anxiety Inventory (BAI) questionnaire and one question about training answered by 2599 participants. Bioimpedance was used to calculate the proportion of muscle mass and BMI and included 164 participants. Results: There was a correlation between higher level of anxiety and higher proportion of muscle mass (r=0.25 p=<0.05) and between higher level of anxiety and higher BMI (r=0.23 p=<0.05). There was a difference (p=<0.05) in level of anxiety between two groups: those who reported regular exercise: Md 4 (Q=6) self-reported a lower level of anxiety than those who didn´t report regular exercise: Md 4 (Q=8). Conclusion: High BMI and high proportion of muscle mass correlate with higher level of anxiety postpartum. There was a correlation between exercise during pregnancy and a decreased level of anxiety.
