Intimate partner physical violence and inadequate weight gain in pregnancy

Abstract Objectives: to evaluate the association between intimate partner physical violence (IPPV) and inadequate gestational weight gain (GWG). Methods: cross-sectional study composed of 554 women who attended four Basic Health Units in the city of Rio de Janeiro between 2005 and 2009. The GWG was calculated through the difference between the final weight of pregnancy and pre-gestational weight. For the measurement of IPPV, the Portuguese version of the Conflict Tactics Scales (CTS-1) was used. Data analysis was based on multinomial logistic regression models, estimating odds ratios and respective 95% confidence intervals for associations between the variables of interest. Results: the prevalence of minor and severe IPPV was 31.6% and 16.3%, respectively. Almost two-thirds of the women had insufficient or excessive GWG. After adjusting the model, it was observed that the presence of IPPV increased by 1.66 (CI95%=1.05-2.64) times the chances of insufficient GWG, compared to couples who did not experience this type of violence. Concerning the excessive GWG, the associations with IPPV were not statistically significant. Conclusion: women who experience IPPV in their relationships are more likely to have insufficient GWG during pregnancy. From this perspective, prenatal care becomes an essential service for screening domestic violence and its possible repercussions.
