This study investigates the relationship between vitamin C intake and obesity prevalence among Korean adults. Based on data of the Korean National Health and Nutrition Examination Survey (2016-2017), a total of 1,356 participants were included in this analysis. Increasing the dietary vitamin C intake resulted in a significantly decreased occurrence of BMI obesity prevalence (p for trend=0.0194) and WC obesity prevalence (p for trend=0.0452). Moreover, increasing the dietary vitamin C intake of Korean adults having a high frequency of eating breakfast resulted in significantly decreased BMI obesity prevalence (p for trend=0.0406) and WC obesity prevalence (p for trend=0.0432). Among the Korean adults who ate out frequently, decreased BMI obesity prevalence was determined with increased intakes of dietary vitamin C (p for trend=0.0193) and total vitamin C (food and dietary supplements) (p for trend=0.0429), whereas significant decrease in WC obesity prevalence was observed with increased dietary vitamin C intake (p for trend=0.0484). Our results provide conclusive evidence that consumption of dietary vitamin C is associated with obesity prevalence in Korean adults, according to their habits of eating breakfast and frequency of eating out.

The purpose of this study was to investigate the comparison of nutrient intake and metabolic syndrome between single person households and non-single person households in elderly subjects. We analyzed data from 2,903 subjects ≥ age 65 who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2013~2015. As a result, single-person households had lower income and economic ability, overall nutrient intake was deteriorated, and the proportion of high-carbohydrate intake was high, compared to non-single person households. After adjusting for potential confounders (sex, age, education, household income, economic activity, smoking status, alcohol consumption, walking frequency, health status, depression status, and dietary factors), the singleperson household showed a tendency of 1.22-fold higher ORs of metabolic syndrome and 1.3-fold higher ORs of hypertriglyceridemia than the non-single-person household. We suggest that the single-person household may be associated with increased prevalence of metabolic syndrome and hypertriglyceridemia in the elderly subjects.

목적 : DEQ-5 설문지를 이용하여 연령과 성별에 따른 건성안 유병률을 조사하고자 하였다. 방법: 강원도에 거주하고 안질환이 없는 남자 141명(35.78±14.703세), 여자146명 (35.19±14.766세), 총 287명(35.48±14.713세)을 대상으로 DEQ-5 설문지를 이용하여 자각적 으로 건성안 진단을 하였다. 6점 이상일 경우 건성안으로 판단하고, 성별과 연령에 따른 건성 안 유병률을 분석하였다. 결과 : 1. DEQ-5 점수 성별에 따른 DEQ-5 평균 점수는 남성이 7.57 ± 4.523이고, 여성이 9.06±4.780로 나타나 여성과 남성사이에 점수 차이는 크게 나타나지 않은 것으로 조사되었다. 연령별 DEQ-5 평균 점수는 10대가 4.44±3.791점, 20대가 7.45 ± 4.500점, 30대가 8.92 ±4.695점, 40대가 10.05±3.962점, 50대이상이 9.95±4.328점으로 나타나 50대에서는 DEQ 평균점수가 약간 감 소되었으나, 연령이 증가할수록 평균점수가 증가하는 것으로 조사되었다. 2. 성별에 따른 건성안 유병률 남성 중에서 건성안이 61.0%이었으며, 여성 중에서 건성안이 73.3%로 나타나 여성에서 건 성안이 더 많은 것으로 조사되었다. 3. 연령에 따른 건성안 유병률 10대는 건성안이 28.0%, 20대는 건성안이 60.4%, 30대는 건성안이 75.4%, 40대는 건성안 이 82.8%, 50대 이상의 경우 건성안이 81.5%로 나타나 연령이 증가함에 따라 건성안이 더 많은 것으로 조사되었다. 결론: 성별에 따른 건성안 유병률은 여성이 남성보다 높게 나타났고, 연령에 따른 건성안 유병 률은 연령이 증가할수록 높게 나타나는 것으로 조사되었다.

This study was performed to estimate the seroprevalence of PRRSV in breeding farms in Jeju 2008 using a commercial enzyme-linked immunosorbent assay (ELISA) kit. The tested sera were randomly collected from a total of 1,947 sera from 9 breeding farms unvaccinated in Jeju. As a result, all breeding farms were seropositive for PRRSV. Seven hundred-eighty six of 1,947 sera (40.4%) were positive for PRRSV. Seropositve rate of PRRSV infection in 9 farms showed various levels: 1%, 8.9%, 9.1%, 43%, 46.9%, 48.2%, 51.6%, 60.9%, 85.5%, respectively. The results confirmed that PRRSV infection has been prevailing in breeding farms in Jeju. Also, these results must be taken into a consideration in strategy establishment for the control and eradication of PRRS.
