Course and prediction of body image dissatisfaction during pregnancy: a prospective study

BACKGROUND: During pregnancy, women`s bodies undergo rapid changes in body weight and body size within a relatively short period of time. Pregnancy may therefore be associated with an increased vulnerability for the development of body image dissatisfaction that has been linked to adverse health outcomes for mother and child. The present study aims to examine changes in body image during pregnancy as well as predictors of body image dissatisfaction. This is the first study using a tailored, multidimensional measure of body image especially developed for the pregnant population. METHODS: A prospective longitudinal design with a quantitative approach was applied. Healthy pregnant women (N = 222) were assessed using standardized instruments at two time points (T1: 18th-22th week of gestation, T2: 33th-37th week of gestation). The impact of demographic, weight- and health-related, behavioral, and psychological factors assessed at T1 on body image dissatisfaction at T1 and T2 was examined using stepwise linear regression analyses. RESULTS: T-tests for paired samples revealed that dissatisfaction with strength-related aspects of body image, dissatisfaction with body parts, and concerns about sexual attractiveness increased significantly from the middle to the end of pregnancy. In contrast, preoccupation with appearance, dissatisfaction with complexion, and prioritization of appearance over function were significantly reduced over time. Stepwise linear regression analyses revealed that factors influencing body image depend on the component of body image investigated. Overall, a low level of self-esteem and a high level of pregnancy-specific worries were risk factors for several components of body image dissatisfaction. Besides these, poor sleep quality, low levels of physical activity, disturbed eating behavior, and higher levels of BMI and weight gain were significant predictors. CONCLUSIONS: The results highlight the multidimensional nature of body image and show positive as well as negative changes during pregnancy. Overall, modifiable psychological, behavioral, and weight-related factors appear relevant to the extent of body image dissatisfaction.
