School lunches in Japan: their contribution to healthier nutrient intake among elementary-school and junior high-school children.

ABSTRACT:

Objective

The role of school lunches in diet quality has not been well studied. Here, we aimed to determine the contribution of school lunches to overall nutrient intake in Japanese schoolchildren.

Design

The study was conducted nationwide under a cross-sectional design. A non-consecutive, three-day diet record was performed on two school days and a non-school day separately. The prevalence of inadequate nutrient intake was estimated for intakes on one of the school days and the non-school day, and for daily habitual intake estimated by the best-power method. The relationship between food intake and nutrient intake adequacy was examined.

Setting

Fourteen elementary and thirteen junior high schools in Japan.

Subjects

Elementary-school children (n 629) and junior
