Factors Related with Induced Abortion among Primigravid Women in Ho Chi Minh City, Vietnam

A case-control study was conducted between July and August 2001 in Ho Chi Minh City to investigate factors associated with having induced abortions among primigravid women aged 16 to 38 years. Interviews were conducted with 87 women undergoing abortion (cases) and 81 pregnant women coming for antenatal care (controls). Multiple logistic regression analysis revealed that older age (odds ratio [OR]=0.84) and being married (OR=0.05) decreased the risk of getting unintended pregnancy leading to abortion. Risk factors of obtaining an abortion were not being exposed to family planning promotion on television (OR=2.28) and not knowing the adverse effects of abortion (OR=10.26). Descriptive analysis of contraceptive behavior showed that 41% of cases had never used contraceptives and the reason for non-usage was lack of knowledge of any type of contraceptives in 43% of the cases. Additionally, only 24% of cases had discussed about family planning with their partners. Effective contraceptive methods should be promoted among young population, both females and males, and they need to be informed of the consequences of abortion. Television programs might be an effective mode of providing the information.
