摘要:AbstractBackground: Food security is a central component of the development agenda in pastoralist communities, especially among those who reside in drought-prone areas.Objective: This study measured the prevalence of household food insecurity and associated factors among pastoralist communities of Borana, Ethiopia. Methods and materials: A community-based cross-sectional study was conducted between July and August 2015 in two pastoralist communities in Borana Zone, Oromia, Ethiopia. Data were collected from 1,058 randomly sampled households through an interviewer-administered structured questionnaire. The data were analysed using SPSS version 21.0. Results: The mean household food insecurity score was 18.21 (value range: 0.00-27.00). Overall, 82.33% of the households were severely food insecure, with 14.56% moderately food insecure. Ownership of private farming land, reliance on crop farming as the main economic activity (β=1.47, p=0.016), and one-way walk time to water sources (β=0.01, p=0.001) were significantly associated with household food insecurity (p<0.05). Likewise, increased family size (β=0.49, p=0.001) and lack of education (β=1.41, p=0.025) were significantly associated with food insecurity. In contrast, dependence on small business (petty trade and shop) as the main economic activity (β=5.14, p=0.001); ownership of milking cow (β=-0.25, p=0.001), bull/heifer (β=-0.16, p=0.002), goat (β=-0.14, p=0.001) or pullet (β=-1.17, p=0.001); ownership of various assets, such as forage (β=-2.50, p=0.009); and participation in village-level saving schemes (β=-1.41, p=0.044) were all significantly associated with reduced household food insecurity. Conclusions: Household food insecurity was widespread in the pastoralist communities of Borana, Ethiopia, affecting a high number of households in all domains: food anxiety, food quality, and quantity of food at the household level. As there were factors that were linked to food insecurity in the study pastoralists, evidence-based innovative interventions via a combination of measures in a medium-to-long-term development plan are vital for sustained household food security.
