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.
