Abstract
BACKGROUND
Obesity and overweight are increasing worldwide and may compromise female sexual function. Our aim was to compare the sexual function of normal and overweight women in pregnancy.
METHODS
A cross-sectional study involving 223 pregnant women: 105 overweight [pre-pregnancy body mass index (BMI) ≥ 25.0 kg/m(2) ] and 118 normal weight (BMI 18.5-24.9 kg/m(2) ), in the 2nd and 3rd trimester of pregnancy. These women were managed at an antenatal clinic of a public university hospital in São Paulo, Brazil, between 2011 and 2014. The Female Sexual Function Index (FSFI) was used. The characteristics of normal and overweight women were compared using two-tailed Student's t- or chi-squared tests. Differences in mean FSFI scores were assessed using the Kruskal-Wallis test. Pearson's correlation coefficient was used to assess the correlation between pre-pregnancy BMI and FSFI scores.
RESULTS
In the 2nd trimester, mean total FSFI scores were similar in overweight (n = 51) compared to normal weight (n = 67) women (21.9 ± 9.8 vs. 21.7 ± 10.4, p = 1.000). In the 3rd trimester, overweight women (n = 54) had significantly lower total FSFI scores than normal weight women (n = 51; 19.1 ± 10.3 vs. 24.5 ± 9.7, p = 0.0004). In the 3rd trimester, overweight women also had significantly lower mean scores in desire, arousal, lubrication, orgasm and dyspareunia domains. We found an inverse correlation between pre-pregnancy BMI and mean 3rd trimester total FSFI scores (r = -0.212, p = 0.030), desire (r = -0.216, p = 0.027) and orgasm (r = -0.222, p = 0.023).
CONCLUSIONS
Overweight women in the 3rd trimester of pregnancy had poorer sexual function compared with normal weight women.
