- Previous studies have shown that sodium excretion is positively related to calcium excretion in the urine. As excessive sodium intake is a common nutritional problem in Korea, we intended to investigate associations among sodium intake levels and calcium status, evaluated by 24 hour recall method and urinary excretion, and bone status. We collected dietary information for non-consecutive three days from 139 young adult women 19~29 years. After classifying the subjects into 4 groups based on the dietary sodium levels by daily total sodium intake (mg) and sodium density (sodium intake per 1000 kcal energy intake), we compared the bone status, nutrient intakes, urinary calcium and sodium excretions. The results showed a positive association between total daily sodium intake and intake of other nutrients. However, no significant differences in nutrients intakes were observed among subject groups classified by sodium density levels. There were no significant differences of bone density among groups by total daily sodium intake as well as by sodium density. While total daily sodium intake showed significantly positive relationship with urinary sodium (p < 0.05) and calcium (p < 0.05), sodium density was not related to urinary excretion of calcium and sodium. Our results suggested that promoting balanced meals providing appropriate amounts of energy intake is the essential component of nutrition education for improving calcium status of young Korean women with excessive sodium intake.

Abstract

- The purpose of this study was to compare the degree of understanding about school foodservice management and environmentally friendly agricultural products between urban and rural elementary school children's mothers. The subjects were 280 elementary school children's mothers who lived in Gunsan city and the nearby countryside. The results are summarized as follows. The mothers in urban schools were higher on the degree of participation (p < 0.01) and interest (p < 0.01), but were lower on the degree of satisfaction (p < 0.001) for school foodservice than rural ones. The best improvement of school foodservice management was improving food tastes and qualities of the foodstuffs in urban schools and sanitation at the service area in the rural schools (p < 0.001). The school foodservice program contributed to cure the unbalanced diets and developing of bodies and minds; there was no difference of urban and rural schools. But eating habits in rural schools were more improved than urban schools (p < 0.001). The primary reason for using environmentally friendly agricultural products was to improve their health and in securing safe foods, there was no difference of urban and rural schools, but generating the farmer's income from the products in rural schools was higher than urban schools (p < 0.001). There are conflicting views between urban and rural schools for the additional costs brought by using the environmentally friendly agricultural products (p < 0.001). The order of preference on using environmentally friendly agricultural products was rice and various grains, vegetables, fruits, livestock, seasoning, etc. In conclusion, our central and local governments should change their roles in financially positive ways and reflect the issues in making the policy effective. Responsible administrators of school food suppliers run the system more faithfully with the above government support.
