An ecological perspective on risk factors for repeat induced abortion in China.

INTRODUCTION: Repeated induced abortion (RIA) is a challenging public health issue. Although many studies have investigated the characteristics of women who experience multiple abortions, most have focused only on limited intrapersonal variables. To frame the analysis, this study used an ecological model integrating intrapersonal, interpersonal and environmental variables to explore factors associated with RIA.

METHODS: Single-site (Maternal and Child Health Hospital, Hubei, China) cross-sectional data were collected from 405 women between July 2015 and November 2015 using a self-administered questionnaire. Characteristics of women who experienced only one abortion were compared to those who had RIA (≥2 abortions).

RESULTS: Among the 316 eligible women who completed the questionnaire, 110(34.8%) experienced one abortion, 206 (65.2%) experienced two or more. Multivariate binary logistic regression analysis showed a higher odds of RIA among women who were older, reported earlier age at sexual debut and reported higher abortion frequency among close female friends. Factors appearing to protect against RIA included higher frequency of partner agreement to women's contraceptive preference.

CONCLUSIONS: Adapting an ecological perspective, this study examined social and environmental factors related to RIA. Our findings emphasize the importance of developing interventions that target both women and their male partner. Group norms relating to contraceptive use also need to be addressed to improve contraceptive use and reduce the risk of repeat abortions.
