본 연구는 한국인 인구집단에서 폭식행동, 음식중독을 식별하고, 해당 증상들이 비만 및 섭식행 동, 정신건강, 인지적 특성과 어떠한 연관성을 보이는지 규명하고자 하였다. 이를 위하여 정상체중 및 비만 체중에 해당하는 한국인 성인 257명을 대상으로 섭식문제(예: 폭식, 음식중독, 음식갈망), 정신건강(예: 우 울), 인지기능(예: 충동성, 정서조절)에 관한 임상심리검사 척도를 측정하였다. 비만 여부와 성별에 따라 그 룹을 나누었을 때, 비만체중 여성에서 폭식행동이 46.6%, 음식중독이 29.3%로 가장 빈도가 높았다. 성향 점수 매칭 후 데이터로 독립성 검정을 수행한 결과, 폭식행동 및 음식중독이 비만체중 집단에서 정상체중 집단보다 더 많이 나타나는 것을 확인하였다. 또한 폭식행동과 음식중독 유무에 각 심리검사 척도 요인이 미치는 영향력을 파악하고자, 전진선택법을 적용한 로지스틱 회귀모델을 구축하였다. 로지스틱 회귀분석 결과, 폭식행동에는 섭식장애, 음식갈망, 상태불안, 정서조절(인지적 재해석) 및 음식중독이 주로 관여하였 고, 음식중독에는 음식갈망, 폭식행동과 함께 비만과 연령의 교호작용, 교육년수가 유의하게 작용하는 것으 로 나타났다. 본 연구는 한국인 성인을 대상으로 한 체계적 연구로서, 폭식행동과 음식중독이 여성 및 비만 인에서 특히 더 많이 나타남을 확인하였다. 폭식행동과 음식중독에는 일부 섭식문제(예: 음식갈망)가 공통되게 관여하나, 정신건강 및 인지적 위험요인에는 차이가 있었다. 따라서 음식중독과 폭식행동은 서로 구 별되는 개념으로 두고, 각각의 기질적·환경적 위험요인을 깊이 있게 탐구하는 것이 필요하다.

This study investigated the association between dietary intake and 10-year risk for CHD predicted from Framingham risk score in Korean adults using the Korea National Health and Nutrition Examination Survey 2019-2020. Eight thousand subjects (3,382 men and 4,618 women) aged 30 years or older were classified into three groups according to the 10-year CHD risk (%). The sociodemographics, anthropometrics indices, blood profiles, and dietary intake were collected. After adjusting for confounding variables, the mean adequacy ratio (MAR) decreased for both men and women as the disease risk increased. The high–risk group was below the MAR criteria, indicating that the overall quality of the meal was not good. The highest consumers of legumes (OR 0.56, 95% CI 0.37-0.84), fruits (OR 0.67, 95% CI 0.48-0.93), and fish (OR 0.60, 95% CI 0.42-0.87) had a 44%, 33%, and 40% lower 10-year CHD risk than lowest consumers in men, respectively. In women, there is no significant relationship between food groups and disease risk. Therefore, improving lifestyle habits such as weight control, increased activity, and adequate food intake, especially legumes, fruits, and fish rich in antioxidant nutrients and bioactive substances, appears to have a potential association with preventing coronary heart disease in Korean adults.

The purpose of this study was to evaluate dietary intake according to the risk of coronary heart disease (less than 10% = low-risk group; 10~20% = middle-risk group) based on Framingham risk score (FRS), on 122 male adult subjects. The body weight and body mass index were not significantly different between the groups, while height of the low-risk group was shown to be significantly high compared to that of the middle-risk group. The daily energy intake was shown to be significantly high in the low-risk group with 1,910.88 kcal, compared to 1,606.63 kcal of the middle-risk group. As a result of analyzing nutrient intake per 1,000 kcal of energy, while the low-risk group had significantly high intake of animal protein, fat, and animal fat compared to the middle-risk group, the intake of plant protein, carbohydrate, and plant iron was found to be significantly low. The daily food intake was shown to be significantly high in the low-risk group (1,445.16 g), compared to the middle-risk group (1,075.12 g). The low-risk group was found to have significantly high intake of sugars, eggs, and beverages compared to the middle-risk group, while mushrooms intake was significantly high in the middle-risk group. Dietary variety score (DVS) was significantly high in the low-risk group with 26.42, compared to 22.66 of the middle-risk group. Dietary diversity score (DDS) was indicated to be significantly high in the low-risk group with 3.70, compared to 3.27 of the middle-risk group. The low-risk group was indicated to have significantly high score in DDS of dairy products and fruit group, compared to the middle-risk group. In the correlation between diversity index of food intake (DVS and DDS) and FRS, DDS was shown to have significantly negatively correlation with FRS after adjusting for confounding factors. To sum up these results, the adult males with low-risk of coronary heart disease had more various consumptions of fruits and milk, compared to the subjects with the middle-risk. The proportion of consuming major food groups such as cereals, meat group, milk, fruits, and vegetables more than a fixed quantity was indicated to be high. Accordingly, dietary habit for intake of various food seems to be necessary, to prevent coronary heart disease.

This study identified problems of the existing ecosystem-based fisheries assessment approach, and suggested new methods for scoring risk and for the estimation of fishery risk index. First, risk scores of zero to two for target and limit reference points for each indicator were replaced by those of zero to three, and the risk scores were calculated from new formulae which were developed in this study. Second, a new method for estimating fishery risk index (FRI) was developed in this study, considering the level of indicators. New method was applied to the Korean large purse seine fishery, large pair trawl fishery and drag net fishery. More precise and detailed risk scores were obtained from the new method, which can explain the risks by the wider range of both risk levels for 'better than target' and 'beyond limit'. The new method for estimating FRI could avoid the basic problem related with duplicated computations of fishery-level indicators, which improved the estimated FRI to be more accurate. Also, a method for estimating variance of FRI using the bootstrap was proposed in this study.

심혈관 질환의 위험도를 조기에 발견해 예방하기 위한 다양한 시도들이 이루어지고 있는 데 질환자를 대상으로 한 많은 연구를 통해 관상동맥 석회화의 판정기준이 마련되었으나 수치가 100 이상이 되어야 진행의 흐름을 예상할 수 있었다. 이에 본 연구는 자각증상이 없는 일반인을 대상으로 칼슘 수치와 체성분 분석, 혈중지질 수치의 상관관계를 수 치화하여 기존 연구와 비교분석하여 칼슘 수치가 낮을 때에도 잠재적인 심혈관 질환의 위험성을 나타낼 수 있을지에 대한 평가를 해 보았다. 연구 결과 체성분 분석에서 칼슘수치가 0-10일 때 와 칼슘수치가 11-100일 때 유의한 상관 관계가 있는 BMI와 WHR을 살펴보면 정상범위의 빈도수가 많아 평균값이 정상범위에 머물렀으나 21%의 상대적인 위 험률이 도출되었으며 지질검사에서도 유의한 상관관계가 있는 HDL과 TG를 살펴보면 정상범위의 빈도수가 많아 평균 값이 정상범위에 머물렀으나 21-40%의 상대적인 위험률이 도출되었다. 또한 상관관계가 없는 BFM과 BMR에서는 표 준이상에서 빈도수가 높아 평균값도 높게 나타났으며 상대적 위험도가 31-93%로 도출되었으며 지질검사에서 상관관 계가 없는 TC가 200 mg/dl이상으로 죽상동맥경화증의 발생이 급격히 증가하여 LDL값이 높게 나타났으며 죽상경화증 의 발생을 억제하기 위해 이미 생긴 죽종에서 콜레스테롤을 제거하는 작용을 하는 HDL의 값도 동시에 증가한 것으로 보인다. 이 때의 상대적 위험률은 43-50%로 도출되었다. 즉 칼슘 수치가 낮을 때에도 심혈관 질환의 발생률이 내재되 어 있음을 알 수 있었다.
