Household dietary diversity (HDD) is an important nutrition outcome measuring the economic ability of a household to access a variety of foods during a determined period. For this, it has been increasingly used as indicator of food security. This paper examines the determinants of HDD. Data for this paper comes from the cross-sectional survey collected from two districts of Illu Ababora Zone, Oromia region of Ethiopia. Overall, 334 farm households of which 71 female headed households and 263 male headed households were surveyed. Twelve different food groups were used to calculate the HDD score, which is a continuous score ranging from 0 to 12. This score was then recoded to a three-level ordered categorical variable. Ordered probit, OLS regression and Poisson regression were used to check for robustness and consistency of the results. The result shows that human capital, natural capitals and physical capitals are the main explanatory factors for HDD variations in the study context. Mediating the utilization of livelihood assets, social relations, institutions, organizations, shocks and seasonality are also explaining variations in HDD. Livelihood strategies such as farm production diversity and non-farm income are significantly and positively influencing HDD. Similarly, livelihood outcomes such as meal frequency and household wealth status are also positively influencing HDD. The current promotion of export crops at the expense of crops diversity will hurt HDD given the apparent poor market-integration, rugged terrain, poor infrastructure development and fragmented institutional arrangements at the study areas.
