IntroductionFood insecurity is a potential predictor of intimate partner violence. This study (1) describes the prevalence of food insecurity and various forms of intimate partner violence experience among women in Mwanza, Tanzania; and (2) assesses the effect of food insecurity and hunger on various forms of women's experience of intimate partner violence longitudinally.MethodsWomen (aged 18-70 years) who reported being in a relationship in the past 12 months, who had participated in the control arms of two randomized controlled trials conducted as part of the MAISHA study were interviewed at four time points (N=1,004 at baseline in 2017). Analyses were conducted in 2022. Associations between food insecurity exposures and intimate partner violence outcomes were assessed, and univariate random effect logistic models were conducted to identify relevant sociodemographic variables (including age, education level, and SES) that were statistically significant. Multivariable random effects logistic models were conducted, including time as a fixed effect, to calculate odds ratios indicating associations between food insecurity exposures and intimate partner violence outcomes.ResultsPrevalence of food insecurity was 47.7%, 55.6%, 47.2%, and 50.8% for each of the 4 waves, respectively, with significant difference in proportion of food insecurity between baseline and Wave 2. Multivariable random effects models indicated that food insecurity was associated with increased odds of exposure to all forms of intimate partner violence outcomes, and hunger was significantly associated with increased odds of experience of all intimate partner violence outcomes, apart from controlling behaviors.ConclusionsResults from this longitudinal analysis of food insecurity and women's reports of intimate partner violence experience in a low- and middle-income country setting indicate that food insecurity is significantly associated with all forms of intimate partner violence, apart from controlling behaviors, among women in this sample in Mwanza, Tanzania. Policy and programmatic implications include the need for integrated intimate partner violence prevention programming to take into account household food needs.Copyright © 2023 American Journal of Preventive Medicine.
