Abstract
As the number of Chinese international students in the Korea continues to rise, it is critical to understand their dietary behaviors changes and nutritional status. As part of the adaptation process of international students, the external influence upon their dietary behaviors is inevitable. The purpose of this study was to analyze the nutritional status of the Chinese female college students in Korea, and to investigate the changes in their dietary behavior after residing in Korea. The subjects were 114 Chinese female college students currently studying in Korea. For this study, general characteristics, daily nutrient and food intakes, dietary behaviors, and nutritional quality were investigated. This survey was implemented for Chinese students from May 2011 to March 2012. Food consumption was assessed using a 1-day 24-hour recall. We observed that most nutrients, namely calcium, iron, zinc, vitamin B2, vitamin C and folate consumption in the subjects is estimated to fall below the EAR for Korean population at 72%, 63.4%, 61.3%, 59.1%, 63.4%, 94.6, respectively. Moreover, the subjects pose a risk of deficiency in folate the most among all the other nutrients which turned out to be the lowest in NAR and INQ scores at 0.41±0.19 and 0.51±0.23, respectively. In the present study, dietary behavior scores comparing eating habits and other dietary patterns before and after residing in Korea were estimated by Chinese students. The behavior scores fell significantly after Chinese students immigrated to Korea (P<0.001). Increased frequency of meal skipping, less consumption of fruits and vegetables, irregular meal pattern, lower serving portion of meals, imbalanced diet, and increased consumption of coffee were observed to be just some of the significant changes among Chinese students before and after residing in Korea. According to changes in dietary behaviors, consumption of most nutrients including dietary fiber, vitamin A, vitamin B group, vitamin C and folate in the Worsened Group were significantly lower than the No Change Group (P<0.05). In conclusion, these results indicated that more unhealthy dietary behaviors were found in Chinese students after residing in Korea and Chinese students residing in Korea showed poor nutritional quality. A follow-up study is needed to assess the nutritional status of Chinese students using blood profile tests. These results would be used to plan a nutritional surveillance program for Chinese students.;본 연구는 최근 급증하고 있는 중국유학생 중 서울지역의 중국 여자유학생을 대상으로 이들의 영양섭취 상태를 평가하고 한국에 온 후의 식행동의 변화를 분석하고자 수행되었다. 2011년 5월부터 2012년 3월까지 모집된 중국 여자 유학생 114명을 대상으로 진행되었으며, 식이섭취상태는 24시간 회상법 (24-hour recall method)을 이용하여 조사하였다. 한국에 거주하는 중국 여자 대학생의 영양 섭취 상태를 살펴본 결과, 칼슘 (72%), 철분 (63.4%,), 아연 (61.3%), 비타민 B2 (59.1%), 비타민 C (63.4%), 엽산 (94.6%) 등 많은 영양소의 섭취가 한국인 기준의 평균필요량(EAR)에 미치지 못하는 것으로 나타났다. 식사의 질을 평가한 결과에서는 엽산의 영양소 적절 섭취 비율(NAR)와 영양밀도지수(INQ)가 다른 영양소에 비해 낮아 질적으로 가장 문제되는 영양소인 것으로 평가되었다. 중국 여자 대학생의 식행동 점수의 총점은 중국에 있을 때보다 한국에 온 후에 낮아졌으며(P<0.001), 특히 아침 결식의 증가, 과일과 야채의 섭취 감소, 불규칙한 식사 패턴, 커피 섭취 증가 등의 부적절한 식행동이 한국에 온 후에 증가한 것으로 나타났다. 식행동 점수가 낮아진 그룹은 식이섬유, 비타민 A, 비타민 B군, 비타민 C 그리고 엽산 등 많은 영양소의 섭취가 식행동 점수가 변하지 않는 그룹보다 유의하게 낮았다 (P<0.05). 결론적으로, 한국에 유학 온 중국 여학생들은 한국에 온 후에 바람직하지 않은 식행동을 갖게 되고 식사의 질이 낮아짐을 알 수 있었다. 추후 중국 유학생을 대상으로 혈액 분석을 통한 영양상태 분석이 필요할 것으로 보이며, 본 연구결과는 중국인 유학생의 보건영양 관련 프로그램 계획을 위한 기초자료로 이용될 수 있을 것이다.
