The Changes in Obesity Prevalence and Dietary Habits in Korean Adults by Residential Area during the Last 10 Years – Based on the 4th (2007-2009) and the 7th (2016-2018) Korea National Health and Nutrition Examination Survey Data / 대한지역사회영양학회지

Objectives@#The purpose of this study was to discover the changes in obesity prevalence and dietary habits in Korean adults residing in various residential areas during the last 10 years. @*Methods@#Data on Korean adults aged 19 years and above was obtained from the 4th (2007-2009) and the 7th (2016-2018) Korea National Health and Nutrition Examination Survey. The subjects were classified into metropolitan 4th : n=5,977, 7th : n=6,651), urban (4th : n=4,511, 7th : n=5,512) and rural (4th : n=3,566, 7th : n=2,570) based on their residence. The general characteristics, nutrient intake, intake amount, food groups, and healthy dietary factors were analyzed. The association between residential areas and obesity prevalence were analyzed by multiple logistic regression. @*Results@#In urban and rural areas, the obesity rate increased in the 7thsurvey compared to the 4th survey, excluding the metropolitan area. The carbohydrate intake decreased, and lipid intake increased in the 7thsurvey compared to the 4thsurvey. Over the same period, the intake of cereals and vegetables decreased, and the intake of meat and processed foods increased. Rural residents had a higher intake of cereals and vegetables, and a lower intake of milk and processed foods than those in metropolitan areas and urban residents. The proportion of subjects who practiced a healthy diet increased in the 7th survey compared to the 4thsurvey. In the 4th survey, there was no relationship seen between the prevalence of obesity and the subject’s residential area, but in the 7thsurvey, the odds ratio of obesity was higher in rural areas than in the metropolitan areas, confirming the regional gap (OR: 1.16, 95% CI=1.00-1.36, p=0.044). @*Conclusions@#This study showed that the obesity prevalence increased in rural residents compared to metropolitan residents, indicating a gap between the regions. The nutrient intake and intake of food groups changed in the 10 years under consideration, and there were differences seen between regions. Therefore, it is necessary to formulate a policy that will reduce obesity prevalence and health inequalities between regions.

Food and nutrient intake status of Korean elderly by perceived anxiety and depressive condition: data from Korean National Health and Nutrition Examination Survey 2013 ~ 2015 / 한국영양학회지

PURPOSE: This study examined the food and nutrient intake of Korean elderly according to the anxiety and depressive condition using the data from the Korea National Health and Nutrition Survey (KNHANES) from 2013 to 2015. METHODS: The participants were 3,504 elderly people over 65 years of age (1,523 in men and, 1,981 in women). The dietary information was analyzed using the 24-hour recall data. The anxiety and depressive state was assessed using the self-reported scale EQ-5D in the quality of life dimension. The subjects were divided into the anxiety · depression group (AD) and non-anxiety · depression group (NAD) according to their anxiety and depressive conditions. RESULTS: In the male elderly, the AD group had a significantly lower education and economic level and higher proportion in living alone than the NAD group. The percentage of eating lunch and dinner alone in the male AD group was higher than that of the NAD group. The female AD group showed less a lower frequency of dinner than the NAD group. The male AD group had a lower consumption of total foods, fish and shellfishes, seaweeds, mushrooms, oils and fats, and seasonings than the NAD group. With regard to the nutrient intake, the male elderly NAD group had more sufficient nutrient intakes than the AD group. In particular, the daily intakes of dietary fiber, riboflavin, niacin, potassium and iron were significantly lower in the AD group. To compare with the nutrient density of the two groups, the vitamin C and niacin intakes were lower in the AD group than in the NAD group. Overall, the nutritional status of the male AD group was significantly lower than that of the NAD group. Meanwhile, the female elderly had showed a smaller difference in nutrient intake according to their anxiety and depressive condition. CONCLUSION: These results of this study show that more nutritional education and emotional support are needed to improve the nutritional status and health of the male elderly with anxiety or depression.

Dietary Habits and Nutritional Status of Young Women according to Breakfast Frequency in Seoul / 대한지역사회영양학회지

OBJECTIVES: Although breakfast is important to nutrition balance, prevention of overeating, and weight control, people in their 20s (males: 55.1%, females: 49.9%) were reported to have the highest rate of skipping breakfast in 2016 Korea Health Statistics. This study aims to examine dietary habits and nutrient intake depending on breakfast frequency among young women in Seoul. METHODS: The subjects were 655 young women in Seoul from August to October 2016, and the survey was performed by using a questionnaire that included general characteristics, dietary habits, and eating behavior. Body composition was determined by bioelectric impedance analysis. Nutritional status was examined by the 24-hour recall method. RESULTS: The participants were classified by breakfast intake frequency; ‘≥ 5 times/week (n=160)’, ‘1–4 times/week (n=327)’, and ‘breakfast skipping (n=168)’. The ‘breakfast skipping’ group had lower frequency and regularity of meals. In addition, the ‘breakfast skipping’ group had a higher frequency of eating-out and late-night meals. There was no difference in total calories between the ‘breakfast skipping’ group and other groups, but the ‘breakfast skipping’ group had significantly low carbohydrate and fiber intakes. The participants showed lower intakes of calories, fiber, vitamin A, vitamin C, niacin, folic acid, calcium, potassium, and zinc in comparison with recommended intakes. Especially, the ‘breakfast skipping’ group had significantly lower fiber, vitamin A, vitamin C, calcium, potassium levels compared to the ‘≥ 5 times/week’ group. For Mean Adequacy Ratio (MAR), the ‘breakfast skipping’ group recorded a ratio of 0.60, which was lower than those of other groups. Index of Nutritional Quality (INQ) including fiber, vitamin C, calcium and phosphorus were significantly lower in the breakfast skipper group, compared to the breakfast eater group. CONCLUSIONS: The ‘breakfast skipping’ group showed low regularity of meals and a high frequency of eating-out and late-night meals. The breakfast regular eater group showed high intake of micronutrients and quality of meals was high in general. Skipping breakfast could lower nutrient intake and quality of meals, which requires attention.
