Objectives: Health status and health behaviors are associated with academic achievement in children and adolescents. The purpose of this study was to investigate whether skipping breakfast and being overweight are related to academic achievement of Korean adolescents. Methods: Cross-sectional data on a sample of 1,652 high-school seniors (942 males and 710 females) drawn from the 2004 Korea Education Employment Panel were analyzed. Results: A higher proportion of males (15.3%) than females (6.1%) was overweight (p < 0.001); 37% of males and 41% of females reported skipping breakfast. Overall test scores were significantly higher for females than males (p < 0.05), and in language and foreign language subjects. However, both males and females who reported skipping breakfast had significantly lower scores in language, mathematics, and foreign language than those who did not report skipping breakfast. Overweight males had a lower probability than normal-weight males of having the highest language scores (OR = 0.52, p < 0.05), but there was no difference among females. Females who skipped breakfast had a lower probability of having the highest scores in language (OR = 0.41, p < 0.05), mathematics (OR = 0.24, p < 0.01), or foreign language (OR = 0.18, p < 0.01), while males had a lower probability of having the highest scores in language only (OR = 0.46, p < 0.05). Conclusion: Skipping breakfast and being overweight are associated with poor academic achievement in Korean adolescents. Eating breakfast and weight control is being discussed as the overlooked factors that may influence better academic achievement.

홍경의(Hong Kyung Eui),강양화(Kang Yang Wha),정효지(Joung Hyojee) 韓國營養學會 2008 Journal of Nutrition and Health Vol.41 No.4

외식소비자들의 외식 건강증진사업 요구도와 실행의지를 분석한 결과를 요약하면 다음과 같다. 첫째, 외식에 포함되는 영양소로 지질, 열량, Na, 섬유소 등을, 건강정보로 비만, 심혈관질환, 암, 당뇨 등과 관련된 내용을 표시하는 것에 대한 요구도가 높았다. 둘째, 외식 건강증진사업 목표인구로는 요구도와 실행의지가 높은 여성, 30대 연령층, 배우자가 있는 대상자, 외식할 때 식당관리 상태 및 식당 음식의 질을 많이 고려하는 사람을 주 대상으로 할 필요가 있다. 셋째, 요구도는 높으나 실행의지는 낮은 50대 이상 연령층, 저학력층 대상자들이 접근하기 용이한 사업 개발이 필요하고, 요구도도 낮고 실행의지도 낮은 남성, 배우자가 없는 대상자 등에 대해서도 건강증진사업의 중요성을 인식시키고 이를 활용하도록 하는 사업을 개발할 필요가 있다. 넷째, 외식산업 건강증진사업을 개발할 경우 식당환경 및 위생관리, 식당음식의 질 관리 등 식당운영을 잘 할 수 있도록 지도하는 사업을 개발할 필요가 있다. 본 연구에 의하면 현재 외식소비자들의 외식 건강증진사업 요구도와 실행의지는 높았다. 그러나 대상자의 특성에 따라 요구도와 실행의지에 차이가 났고, 각각의 점수가 아직도 그렇게 높지 않은 점을 감안하여 건강증진사업을 계획하여야 될 것으로 나타났다. 이를 위해서 외식 소비자들에게는 건강증진사업 참여가 본인의 건강에 이익이 된다는 것을 알리는 활동이 포함되어야 한다. 외식 제공자들에게는 영양정보나 건강정보가 표시되는 음식을 만들 수 있는 기술개발, 식당환경 향상 등의 활동이 포함되는 것이 필요하고, 건강증진사업을 주관하는 측에게는 제공되는 영양 및 건강정보의 정확성을 소비자들이 확신할 수 있도록 하는 제도적 인증체계의 구축, 외식 제공자들의 음식 영양성분 분석 의뢰를 처리해 줄 수 있는 연구소 신설 등이 건강증진사업 활동으로 포함되는 것이 필요하다. This study examined the needs and practice willingness for the health promotion program of restaurant industry among Seoul residents. Using structured self-administered questionnaires, data on subjects’ general characteristics, health status, and eating out behavior characteristics, the needs and practice willingness of the health promotion program for restaurant industry were collected from 765 adults above the age of 19. The needs for nutrition labeling such as fat, calorie, sodium, fiber, and the practice willingness for consuming nutrition labeled food were high. Results showed that gender, restaurant’s management status, and food quality status were significant indicators for needs for health promotion program. Education duration, food quality status, and the frequency of eating out were significant variables for practice willingness. The results imply that health promotion program for the restaurant industry should be based on the consumer’s characteristics. Also, the results imply the necessity of several activities such as social marketing to inform the benefit of participation in the health promotion program for consumers, guidance to maintain the food quality and improve the ambiance of restaurant for suppliers, and the new establishment of research centers to validate the labeled information on meals and analyze the nutrients of the meals for agencies.

Objectives: The response concordance between interviewer-assisted interviews and telephone survey was introduced in the Community Health Survey for the quality control and examining the association between the response concordance and related variables is required. Methods: Total 22,665 were participated in the 2014 Community Health Survey, Korea. Multivariate logistic regression analysis was performed on the response concordance for the five questions; self-rated health status (SRH), car driving, sleep time, health check-ups, and doctors diagnosed hypertension (DDH). Response concordance was investigated by gender, age (19-39, 40-64, 65-74, ≥75), residential areas (urban, rural), comorbidity, and interval period (<6 days, 6 days ≤) defined as the different days between interviewer-assisted interviews and telephone survey. Results: Women (12,658, 55.9%), urban residents (15,486, 68.3%), age 40-64 years (10,732, 47.4%), and comorbidities (6,911, 30.5%) were predominant among study population. The association of SRH were observed for women [1.08 (95% confidence interval [CI], 1.02-1.14)] and age group 40-64 [0.79 (95% CI, 0.73-0.85)], 65-74 [0.60 (95% CI, 0.55-0.66)], ≥75 [0.43 (95% CI, 0.38-0.48)], rural [0.84 (95% CI, 0.79-0.89)], and comorbidities [0.90 (95% CI, 0.78-1.04)]. Gradual decrease in car driving was observed by the age groups 40-64 [1.43 (95% CI, 1.17-1.74)], 65-74 [1.78 (95% CI, 1.32-2.40)], and ≥75 [1.87 (95% CI, 1.29-2.70)]. The variables showing significant association with the interval period (6 days ≤) were SRH [0.88 (95% CI, 0.83-0.93)] and sleep time [0.85 (95% CI, 0.77-0.93)], and rural area residents showed lower response concordance with SRH [0.84 (95% CI, 0.79-0.89)], sleep time [0.64 (95% CI, 0.58-0.70)], health check-ups [0.90 (95% CI, 0.83- 0.99)], and DDH [0.71 (95% CI, 0.64-0.80)] except for car driving [1.21 (95% CI, 0.90-1.26)]. Conclusions: The factors associated with the response concordance varied and having comprehensive understanding about the survey is necessary to assess the quality of the data.
