ABSTRACT Background: Adequate fruit and vegetable consumption during early childhood plays a crucial role in preventing all forms of malnutrition, supporting optimal growth and development, and reducing the risk of NCDs later in life. Despite these benefits, children’s intake often falls below recommended levels globally. In Ethiopia, no published study has specifically assessed adequate fruit or vegetable intake among young children aged 2-5 years, despite being a critical period to establish a healthy dietary habit. National data on zero fruit or vegetable consumption among children under two years indicate very low intake, suggesting that inadequate consumption may persist into the preschool years. However, evidence on the magnitude of adequate fruit or vegetable consumption and its associated factors among children aged 2-5 years remain limited. Objective: The aim of this study was to assess adequate fruit or vegetable consumption and associated factors among young children in Waja Town, North east Ethiopia, 2025. Methods: A community based cross sectional study was conducted from August 05 to September 01 2025 among mothers of young children aged 2-5 years living in Waja Town. A two stage cluster sampling technique was employed to select a total of 636 study participants and data on fruit and vegetable intake was collected using interviewer administered semi quantitative FFQ. Binary logistic regression was used; variables with p < 0.25 in bivariate analysis were included in multivariable analysis, and those with p < 0.05 were considered statistically significant. The direction and strength of association were interpreted using AOR at 95% confidence intervals. Result: The prevalence of adequate fruit or vegetable consumption was 11.8 %( 95% CI: 9.3¬-14.3%). Parental fruit and vegetable consumption [AOR =4.253, 95% CI (2.148, 8.423)], household food security status [AOR =0.257, 95% CI (0.105, 0.634)] and farm production diversification [AOR=2.566, 95% CI (1.266, 5.198)] were significantly associated with adequate fruit or vegetable consumption. Conclusions and recommendations: The prevalence of adequate fruit or vegetable consumption among young children was very low. Therefore, responsible stakeholders should strengthen interventions that improve parental fruit and vegetable consumption, farm production diversification, and household food security.
