Abstract

This study was conducted to estimate the prevalence of constipation, bowel habits and nutrient intakes of college students. The subjects were 353 college students (166 males and 187 females) aged 19 to 29 years in Incheon area. The subjects were asked about bowel habits and dietary intake using questionnaires during march, 2008 and the prevalence of functional constipation (FC) was based on the Rome II criteria. The prevalence of FC in male and female students was 12.7% and 28.9%, respectively. The prevalence of self-reported constipation in male and female students was 12.0% and 36.9%, respectively. Both were higher in female students compared to male students. Among the subjects that have self-reported constipation, proportions of FC were 35.0% in male students and 55.1% in female students. Of subjects that did not self-reported constipation, the proportions of FC were 9.6% in male students and 13.6% in female students. Over 90% of respondents that self-reported constipation in male students, had neither visited a hospital and nor used laxatives or functional foods for constipation relief. Seventy five point three percent of male students, and 40.1% of female students, had a defecation frequency of over 5 times per week (p < 0.001). Ratios intaken under the estimated average requirement (EAR) of Vit A, Vit C, folic acid and Ca were over the 50% regardless of functional constipation. Mean daily consumption of total dietary fiber was 15.0 g/day in male students and 13.5 g/day in female students. According to these results, both functional constipation and self-reported constipation are more frequent in female college students and further studies are required in case-control study and related to psychological factors as well as nutrients to relieve of constipation.

대학생들의 변비유병률과 배변습관을 알아보고 영양소섭취 상태를 알아보고자 인천지역 대학교에서 건강관련 교양강의를 듣는 수강생들을 대상으로 (남자 166명, 여자 187명) 설문조사와 신체계측 및 3일간 식이섭취 조사를 실시한 결과는 다음과 같다. 조사 대상자의 평균 연령은 남학생 23.5세, 여학생 20.9세이었으며, 자택에서 거주하는 비율이 가장 많았으며 자취, 기숙사, 하숙이나 친척집에 거주하는 순이었다. 남학생의 63.9%, 여학생의 63.1%는 21~40만원의 용돈을 받고 있었고 지난 2개월 동안 남학생의 45.2%, 여학생의 47.1%는 체중을 유지하고 있었다. 로마기준 II를 이용하여 조사한 기능성 변비유병률은 남녀 각각 12.7%, 28.9%, 자의적 변비 유병률은 남녀 각각 12.0%, 36.9%로 여학생이 남학생에 비해 유의적으로 높았으며 일반사항에 따른 기능성 변비와 자의적 변비의 차이는 보이지 않았다. 자의적 변비 중 남학생의 35.0%, 여학생의 44.9%만이 기능성 변비의 진단기준에 부합하였고, 본인은 변비가 아니라고 응답했지만 기능성 변비의 진단기준에 부합한 경우는 11.4%이었다. 본인이 변비라고 인식하는 경우 남학생의 94.7%, 여학생의 91.0%는 의료기관을 방문한 경험이 없었고 남학생은 모두 변비약이나 건강기능식품을 이용하고 있지 않았으며 여학생은 변비 완화를 위해 10.3%가 변비약, 11.8%가 건강기능식품을 복용하고 있었다. 배변습관 조사 결과 남학생의 75.3%, 여학생의 40.1%는 주 5회 이상 배변을 하고 있었고, 변의 양은 2 cup 이상이라고 응답한 경우가 남학생은 93.4%, 여학생은 75.9%로 남학생이 많은 경향을 보였다. 남녀 모두 대상자의 70%정도가 배변 후 상쾌하다고 하였으며 남학생의 49.4%, 여학생의 24.6%만이 규칙적으로 배변을 하였다. 신체계측치와 영양소 섭취량 분석 결과 기능성 변비와 자의적 변비 유무에 따른 차이는 보이지 않았으나 단백질의 경우 성별이나 변비 유무와 상관없이 RI에서 UL 사이로 섭취하는 비율이 가장 높았고, 남학생은 여학생에 비해 EAR 보다 낮게 섭취하는 비율이 유의적으로 높았다. 비타민 C, Vit $B_2$, 엽산, 칼슘, 아연의 섭취는 EAR 이하로 섭취하는 비율이 모두 50%를 넘어 영양소의 섭취량이 매우 낮음을 알 수 있었고 특히 엽산은 남녀 모두 95% 이상이 EAR 이하로 섭취하고 있어 섭취 부족이 심각하였다. 변비와 관련이 있는 것으로 알려진 식이섬유 섭취량은 1,000 kcal당 섭취량으로 환산에 남학생은 8.5 g, 여학생은 8.9 g으로 한국인 영양섭취기준의 식이섬유 충분섭취량에 훨씬 못 미치는 수준이었다. 여학생의 경우 기능성 변비의 유병률은 28.9%, 자의적 변비의 유병률은 36.9%로 조사되었는데, 본인은 변비가 아니라고 응답했지만 기능성 변비의 진단기준에 부합한 경우도 13.6%이며 본인이 변비라고 응답한 경우의 대다수는 의료기관 방문이나 약물, 기능성 식품 섭취 같은 노력도 하지 않고 있어 만성적 변비로 인한 질병의 위험이 우려된다. 또한 식이섬유 섭취를 비롯한 각종 영양소들도 균형 있는 섭취를 하고 있지 않아 이후 다가올 임신기와 수유기의 영양문제로 이어질 것이므로 올바른 영양섭취를 비롯한 적절한 영양교육이 활성화 되어야겠다.
