24시간 소변 분석, 식사기록법 및 음식섭취빈도조사에 의한 여자 성인의 나트륨 섭취량 조사

This study assesses the sodium intake of adults by 24-hour urine analysis, dietary records review and a food intake questionnaire. Subjects were 236 adult female in Daegu. The results are summarized as follows: Sodium intake as indicated by the 24-hour urine analysis was 5,805.4 ± 3836.8 ㎎. This was significantly higher than intake indicated by dietary records (4415.4 ± 1935.1 ㎎) and the dish frequency questionnaire (DFQ 55)(4293.5 ± 1526.5 ㎎). The results of the 24-hour urine analysis and DFQ 55 showed that sodium intake was higher for the 65-to-74-year-old age group than for other age groups (p < 0.05, p < 0.05). Review of dietary records to examine typical sodium intake by food groups showed that 53.7% of the sodium consumed by subjects in all age groups came from seasonings and spices (2399.0 ± 1526.5 ㎎). The analysis of sodium intake by food groups using DFQ 55 showed 34.2% of their sodium came from consumption of kimchi (p < 0.001) and kimch, soup, stew and fish jorim accounted for 57.8% of total sodium intake. The results indicate positive correlation between age and sodium intake, as shown by the 24-hour urine analysis and food intake questionnaire (p < 0.05). Therefore, these results would be valuable as basic data for planning nutrition education for sodium intake reduction.
