The study was conducted from July to October 1995. Children
aged 7–11 y were selected from 10 schools in 3 neighboring villages
in Bogor District, West Java, Indonesia. Schoolchildren
usually eat 1–3 meals/d at home, which consist of rice with side
dishes such as chili sauce, salted fish, and vegetables and receive
pocket money (US$0.05–0.10) to buy snacks from vendors near
school. Children eat fruit once or twice per month.
