초록

본 연구에서는 성인기 초반에 있는 대학생 118명을 대상으로 나트륨 섭취를 간단하게 평가할 수 있는 소변 중 salt signal을 사용하여 나트륨 섭취량을 추정하고 이에 따른 나트륨 섭취 관련 식행동 및 식태도를 조사하였으며, 그 결과는 다음과 같다. 연령 및 신체계측 분석 결과 소변 중 salt signal에 따른 과잉섭취군의 경우 남자 대상자의 비율이 적정섭취군에 비해 유의적으로 높았으며 수축기혈압이 높은 경향을 보였다. 또한 체질량지수는 두 군간 유의한 차이를 보이지 않았으며 생활습관 조사 결과 과잉섭취군의 경우 음주를 하는 비율이 적정섭취군에 비해 유의적으로 높게 나타났다. 나트륨 관련 식태도에 대해 분석한 결과 11가지 항목에 대한 식태도 총 점수는 적정섭취군과 과잉섭취군에서 각각 35.50점과 33.45점으로 적정섭취군이 과잉섭취군에 비해 긍정적인 나트륨 관련 식태도를 가지는 것으로 나타났다(P<0.05). 나트륨 관련 식행동에 대해 분석한 결과 식행동 총점은 소변 중 salt signal에 따른 두 군간 유의한 차이를 보이지 않았다. 그러나 나트륨 관련 영양지식을 조사한 결과 나트륨 관련 영양지식 총점에서 12점 만점 중 적정섭취군이 9.77점으로 과잉섭취군의 8.82점에 비해 유의적으로 높은 점수를 보였다(P<0.05). 소변 중 salt signal과 나트륨 관련 식태도, 식행동 및 영양지식과의 상관관계를 분석한 결과 연령, 성별 및 체질량지수를 보정했을 때 소변 중 salt signal에 따른 소금 함량은 나트륨 관련 식태도 총점과 음의 관련성을 보였다. 이상의 연구 결과를 종합하여 볼 때 대학생에서 소변 중 salt signal에 따라 과다한 소금 섭취를 보인 대상자의 경우 적정섭취를 보인 대상자에 비해 나트륨 관련 식태도가 좋지 않고 영양지식도 낮은 것으로 나타났다. 이와 같은 결과를 통해 소변 중 salt signal로 추정한 나트륨 섭취와 나트륨 관련 식행동과의 관련성을 제시할 수 있었다.

The purpose of this study was to evaluate salt-related dietary attitudes, behaviors, and nutrition knowledge according to urinary salt signal of university students. Based on urinary salt signal, we classified subjects into an "adequate Na intake (ANI)" group (n=52) (salt ${\leq}6g$) and "excess Na intake (ENI)" group (n=66) (salt >6 g). Subjects were asked about general characteristics, lifestyle, salt-related dietary attitudes, behaviors, and nutritional knowledge using questionnaire. The ENI group had more subjects who were drinkers (P<0.05) compared to the ANI group. The ENI group (33.45) showed a significantly lower score in terms of salt-related dietary attitudes compared to the ANI group (35.50) (P<0.05). There was no significant difference in the total score of salt-related dietary behavior between the groups. The score of nutrition knowledge was significantly higher in the ANI (9.77) group than in the ENI (8.82) group (P<0.05). The correlation analysis indicated that the urinary salt signal had a negative correlation with the salt-related dietary attitude score after adjustments for age, sex, and body mass index (r=-0.2100, P<0.05). These results support the validity of using the urinary salt signal to simplify estimation of sodium intake.
