Intimate partner violence and nutritional status among nepalese women: An investigation of associations

Abstract

Background: Malnutrition among women in Nepal persists as a major public health burden. Global literature suggests that domestic violence may have a negative impact on women's nutritional status. The contribution of intimate partner violence (IPV) to increased stress levels, poor self-care including the consumption of less food and, in turn, malnutrition has been documented. However, there is little empirical evidence on IPV and its relationship with women's nutritional status in Nepal and thus, this paper assesses these associations. Methods: We used data on non-pregnant married women (n = 3293) from the 2016 Nepal Demographic and Health Survey (NDHS). The primary exposure variable was whether the women had ever experienced physical, sexual, or emotional violence or controlling behaviours by a current or former partner, based on her responses to the NDHS domestic violence questions. The primary outcome variables were three indicators of malnutrition: under-weight (BMI < 18.5), over-weight (BMI > 25), and anemia (Hb < 11.0 g dL). We used logistic and multinomial regression models, adjusted for potential socio-demographic and economic confounders, as well as clustering, to examine associations between IPV exposure and malnutrition. Results: Approximately 44% of women had experienced at least one of the four types of IPV. Among them, around 16, 25%. and 44% were underweight, overweight, or anemic, respectively, compared to 13, 29, and 35% of women never exposed to IPV. We did not find any associations between underweight and any of the four types of IPV. Overweight was associated with physical violence (adjusted RRR = 0.67, P < 0.01, CI = 0.50-0.88) and severe physical violence (adjusted RRR = 0.53, P < 0.05, CI = 0.32-0.88) Controlling behaviors were associated with anemia (adjusted RRR = 1.31, P < 0.01, CI = 1.11-1.54). Conclusions: Among married Nepalese women, physical violence appears to be a risk factor for one's weight and controlling behaviors for one's anemia status. Additional, rigorous, mixed-methods research is needed to understand the reporting of IPV and what relationships do or do not exist between IPV experience and nutrition both in Nepal and in other settings.
