Food routines are an ecocultural asset of Latino families. This cluster-randomized trial with 248 children (M[subscript age] = 67 months; 50% girls; 13 schools) investigated the impact of a 4-week family program designed to capitalize on food routines in improving Latino kindergarteners' outcomes in the United States. There were moderate-to-large impacts on child vocabulary (especially food-related) at end-of-treatment and the 5-month follow-up, and suggestive evidence of moderate impacts on approaches to learning (ATL; including ATL math) and executive function at the 5-month follow-up (d = 0.38-0.95). There were no statistically significant impacts on children's math or literacy skills. A strengths-based, culturally responsive family intervention that is integrated into Latino family life can improve the skills needed to succeed in school.
