This study assessed the 8-week nutrition and physical activity program "Food and Fun," adapted for low-income Spanish-speaking mothers and their children. Fruit/vegetable consumption, physical activity, and other characteristics were measured at baseline and at the end of the program. The final sample consisted of 7 mothers and 13 children. Among mothers, there was a significant increase in vigorous physical activity (p =.045). Among children, there was a significant increase in fruit and vegetable consumption (p =.05) and in physical activity (p =.02). This program may be effective in promoting healthy nutrition and physical activity among low-income Latinas and their children.
