The objective of this study was to generate evidence for strengthening the local food system to contribute to improved dietary diversity among children in Ethiopia.

A community-based cross-sectional survey.

The study was conducted in the Amhara, Oromia and Somali regions of Ethiopia.

A total of 1475 children aged 6–23 months were included. Children requiring special care or not permanently residing in the study areas were excluded.

The primary outcome measure was the adequate Minimum Dietary Diversity, defined as the consumption of at least five of the eight defined food groups in the previous 24 hours.

Only 25.6% of children met the adequate minimum dietary diversity requirement. Children from households with backyard gardening (Adjusted odds ratio (AOR)=1.43, 95% CI 1.08 to 1.88), access to communication devices (AOR=1.99, 95% CI 1.51 to 2.64), attendance at cooking demonstrations (AOR=1.99, 95% CI 1.44 to 2.74), use of labour-saving and time-saving technologies (AOR=1.55, 95% CI 1.15 to 2.09) and irrigation use for crop production (AOR=1.78, 95% CI 1.26 to 2.52) had higher odds of meeting adequate minimum dietary diversity. Residence was strongly associated with dietary outcomes: children in Amhara had more than seven times the odds of achieving adequate minimum dietary diversity of children compared with Somali (AOR=7.56, 95% CI 4.92 to 11.62), while those in Oromia had nearly twice the odds (AOR=1.74, 95% CI 1.17 to 2.60).

Dietary diversity among children was low in the study areas. Strengthening local food systems through promotion of backyard gardening, cooking demonstrations, irrigation use, communication access and appropriate technologies could improve children’s dietary diversity. Regional disparities highlight the need for context-specific strategies, particularly to address the low dietary diversity in children.
