Japan still has been concerned about having a salt intake that is more than the recommended value worldwide( 1 – Reference Zhou, Stamler and Dennis 3 ), although the WHO( 4 ) published new guidelines for recommended intake levels of sodium for adults and children. Particularly, they are concerned that the average salt intake in Japan, an eastern Asian country, is higher than other developed countries( Reference Stamler, Elliott and Dennis 2 , Reference Zhou, Stamler and Dennis 3 ), even though , according to the National Health and Nutrition Survey in Japan( 5 ), salt intake has been continuously decreasing because of the westernisation of the Japanese diet and the use of home refrigerators, instead of salt-preserving. However, the result of a previous study shows that younger Japanese consume almost the same amount of sodium as older people. The authors concluded that people cannot be expected to voluntarily reduce salt intake without encouragement. Another previous study( Reference Mori, Mori and Yamori 7 ) shows a significant effect of the nutrition project towards salt intake reduction among children by urinary analysis. The school program for healthy eating could be an excellent method for maintaining the Japanese diet. The aim of the present study was to assess the effect of the school's nutrition project on salt intake reduction by the analysis of overnight urine.

First, we conducted 3 varieties of nutrition projects( Reference Mori, Mori and Yamori 7 ) to encourage 3 classes and to set 2 classes as a control at Year 4 in 2 public elementary schools in Choshi city. We checked the change of sodium concentrate in the overnight urine specimens collected before and after the intervention, in order to investigate the effect of the Food Education Program. The value of salt intake was estimated from the sodium and creatinine concentration in the overnight urine.

(Repeated ANCOVA, followed by fisher's LSD (Salt intake 0w as a covariates))

When compared with the mean of estimated salt intake at pre (0w) in the intervention group, significant differences were found (p < 0·05) in both the means at post (3w) and follow up (13w). On the other hand, no significant difference (p > 0·05) was found among the means of estimated salt intake over the 3 intervals (0w, 3w, 13w) in urine measurement in the control group. This result suggests that the school's nutrition project might have a benefit on reducing the salt intake among Year 4 pupils. The enhancement and improvement of school's nutrition projects are needed for its efficacy to be made.
