This study was performed to investigate the consumption of coffee beverages and energy contribution ratios of coffee beverages and accompanying snacks by college students in Deajeon City and Chungnam Province in Korea. Questionnaire survey, dietary survey, and snack survey using food record method during 3-days were carried out. As a result, we found that 86.9% of male students and 75.6% of female students consumed coffee beverages usually, with no differences between the two groups. However, the frequency of coffee beverages consumed by female students out-numbered that of male students by 1 cup a day to 1-2 cups a week (p<0.05). Furthermore, male students most likely consumed coffee beverages at schools or academies, but female students consumed them at coffee shops (p<0.01). The reasons male students gave to consume coffee beverages were for scent, taste, fatigue, and to stay awake. Similarly, the reasons female students gave to consume coffee beverages were for scent, taste, habit, and to stay awake (p<0.01). Fully 58.1% of male students and 80.0% of female students ate snacks along with coffee beverages (p<0.01). Most male students substituted a coffee beverage and accompanying snack for a regular meal once a month. Female students were doing it at most 2-3 times a month (p<0.05). The mean daily dietary energy intake of male students was 1,924 kcal/d, and of female students was 1,518 kcal/d (p<0.001), which both were below the estimated energy requirements. Male students obtained 285.6 kcal/d and female students obtained 289.5 kcal/d from coffee beverages and accompanying snacks. There was a significant different in dietary intake of energy (p<0.05), calcium, and iron (p<0.001) for each ratio of reference intake between male and female students. The students who ate larger amounts of coffee beverages and accompanying snacks consumed less dietary energy, protein, calcium, and iron, respectively (p<0.05). These results show that many students consume coffee beverages regularly and obtain large amounts of energy from coffee beverages and accompanying snacks. It also shows that student's dietary nutrient intake tends to be poorer, as he or she obtains more energy from coffee beverages and accompanying snacks. Therefore, it is critical to monitor the influence of consumption of coffee beverages and accompanying snacks on the dietary nutrient intakes and health of college students, and to provide nutrition education about the proper consumption of coffee beverages and accompanying snacks based on scientific evidence.

목적: 대전지역 대학신입생들의 굴절상태와 안광학상수를 측정하여 성인의 굴절이상 변화에 미치는 요인들을 분석하였다. 방법: 2008년 3월과 2009년 3월 2회에 걸쳐 76명(남 23명, 여 53명)을 대상으로 기본신체검사, 자동굴절검사, 각막곡률반경, 전방깊이, 안축장을 현성 및 조절마비 상태에서 측정하였다. 결과: 등가구면 굴절이상도는 -0.080±0.301D(p=0.001) 근시방향으로 진행하였고, 각막곡률반경은 -0.015±0.040 mm(p=0.000) 감소하였다. 전방깊이는 0.036±0.066 mm(p=0.000) 증가하였으며 안축장의 변화는 유의하지 않았고(p=0.274), AL/CR 비는 0.004±0.020(p=0.004) 증가하였다. 각막곡률반경 변화량과 굴절이상도 변화량은 양의 상관성이 있었고(r=0.578, p=0.000) 굴절이상도 변화량과 AL/CR 비의 변화는 음의 상관성이 있었다(r=-0.542, p=0.000). 굴절이상도 변화량과 안축장 변화량의 상관성은 유의하지 않았다(r=-0.074, p=0.367). 굴절이상도에 따른 변화에서 근시군의 등가구면 굴절이상도가 -0.134±0.316D 증가하여 원시나 정시보다 변화량이 가장 컸다. 근시군에서 굴절이상도 변화와 각막곡률반경 변화는 양의 상관성을(r=0.664, p=0.000), AL/CR 비 변화와는 음의 상관성을 보였다(r=-0.600, p=0.000). 각막곡률반경 변화와 AL/CR 비 변화는 음의 상관성을 보였다(r=-0.719, p=0.000). 정시군에서 굴절이상도 변화와 안광학성분 변화의 상관성은 유의하지 않았다. 원시군에서 굴절이상도 변화와 각막곡률반경 변화만 양의 상관성을 보였다(r=0.490, p=0.024). 결론: 이상으로부터 성인근시도의 증가는 각막곡률반경 변화 및 AL/CR비의 변화와 관련이 있으며, 성인근시의 원인은 안구성장보다 각막곡률반경의 변화가 더 큰 영향을 미치는 요소로 추정된다.
