Domestic violence as risk factor for unwanted pregnancy and induced abortion in Mulago Hospital, Kampala, Uganda

OBJECTIVE To compare pregnancy intention and domestic violence among women with induced and spontaneous abortion. METHOD Case-control study in Mulago Hospital, Uganda, from September 2003 to June 2004 of 942 women seeking post-abortion care. Direct inquiry, records review and clinical examination identified 333 with induced abortion (cases) and 609 with spontaneous abortion (controls), who were compared regarding socio-demographic characteristics, contraceptive use, domicile (rural or urban, nuclear or extended families), pregnancy intention, household decision-making and domestic violence. Data was analysed with EPI-INFO and STATA, using Student t-test and analysis of variance for continuous and chi-square for categorical variables. Stratified and multivariate logistic regression analyses were used to adjust for confounding and interaction at the 95% confidence level. RESULTS Cases significantly differed from controls as they were younger or more often single; had lower parity and education, less household decision-making and fewer living children. They were similar to controls (P > 0.05) regarding employment, spouse's age, years spent in marital relationship and domicile. Cases more frequently (P < 0.001) had mistimed, unplanned or unwanted pregnancy at conception and presentation. Cases were more likely to have a recent history of domestic violence (physical, sexual or psychological) [OR: 18.7 (95%CI: 11.2-31.0)] after adjusting for age, pregnancy intention and marital status. CONCLUSION Domestic violence is a risk factor for unwanted pregnancy and induced abortion among women seeking post-abortion care.
