Associations between Exposure to Unhealthy Food Outlets Within Residential District and Obesity: Using Data from 2013 Census on Establishments and 2013-2014 Korea National Health and Nutrition Examination Survey: Yoonjung Kim, Sung Nim Han; Korean J Community Nutr 2016;21(5):463-476.

OBJECTIVES
Environmental, social and personal factors influence eating patterns. This study aimed to investigate the relationship between unhealthy food outlets within a residential area and obesity using nationally representative Korean survey data and data from the Census on Establishments.
METHODS
Data on the food intakes and socioeconomic variables of a total of 9,978 adults aged â‰¥ 19 years were obtained from the 2013-2014 Korea National Health and Nutrition Examination Survey. Geographic locations of restaurants were obtained from the 2013 Census on Establishments in Korea. Administrative area was categorized into tertiles of count of unhealthy food outlets based on the distribution of number of unhealthy food outlets among all urban (Dong) and rural (Eup or Myun) administrative districts in Korea. Multilevel logistic regressions model were used to assess the association between the number of unhealthy food outlets and obesity.
RESULTS
People living in the district with the highest count of unhealthy food outlets had higher intakes of fat (45.8 vs. 44.4 g/day), sodium (4,142.6 vs. 3,949.8 mg/day), and vitamin A (753.7 vs. 631.6 ÂµgRE/day) compared to those living in the district with the lowest count of unhealthy food outlets. A higher count of unhealthy food outlets was positively associated with frequent consumption of instant noodles, pizza, hamburgers and sandwiches, sweets and sour pork or pork cutlets, fried chicken, snacks, and cookies. Higher exposure to unhealthy food outlets was associated with increased odds of obesity (1st vs. 3rd tertile; OR 1.689; 95% CI 1.098-2.599).
CONCLUSIONS
A high count of unhealthy food outlets within a residential area is positively associated with the prevalence of obesity in Korea. The results suggest that food environmental factors affects the health outcomes and interventions aiming to restrict the availability of unhealthy food outlets in local neighborhoods may be a useful obesity prevention strategy.

Characteristics of Infants' Temperaments and Eating Behaviors, Mothers' Eating Behaviors and Feeding Practices in Poor Eating Infants: Yoonjung Kim, Young Shin Han, Sang Jin Chung, Yoonna Lee, Sang Il Lee, Haymie Choi; Korean J Community Nutr 2006;11(4):449-458. Published online August 31, 2006

Abstract PDF: The purpose of this study was to determine the characteristics of infants' temperaments and eating behaviors, mothers' eating behaviors and feeding practices in poor eating infants. The participants were 80 infants of 12 - 24 months (27 poor eaters and 53 matched normal controls) from a hospital and a public health center. Mothers were questioned about their eating behaviors and feeding practices, and infants' temperaments, eating behaviors, and nutrient intakes by one day food recall. Subjects were divided by mean nutrient adequacy ratio (MAR, < 0.75; poor eater). Intakes of Ca, P, Fe, Zn, thiamin, riboflavin, niacin, vitamin C, E, folate were below 75% RDA in poor eaters, whereas protein, thiamin, riboflavin, vitamin B6, C, folate exceeded 125% RDA in good eaters. Rhythmicity of infants' temperaments and eating behaviors, restriction of mothers' eating behaviors and feeding practices were significantly lower, whereas activity levels of infants' temperaments were higher than good eaters. In multiple logistic regression model of poor eaters, activity of infants' temperaments (T, OR: 1.19, CI: 1.05 - 1.35) and attention spans of infants' eating behaviors (A, OR: 1.18, CI: 1.03 - 1.35) were significantly positive, whereas rhythmicity of infants' eating behaviors (R, OR: 0.79, CI: 0.67 - 0.94) was significantly negative [E (the logit) = -6.8644 + 0.1712 x T - 0.2337 x R + 0.1641 x A]. Our findings suggest that examination of eating behaviors, feeding practices, and temperaments will help target interventions to improve infants' food intakes, and these variables should be examined at the time of nutrition counseling.

Effects of the Life Style and Self-Recognition of Health Conditions on the of Body Fat % in Hotel Culinary College Students: Sookhee Kim, Kyunghee Joung, Yoonjung Kim; Korean J Community Nutr 2005;10(6):825-834. Published online December 31, 2005

Abstract PDF: This study was to investigate the effects of the body fat % on life styles and self-recognition of health conditions in hotel culinary college students. This survey was conducted using the questionnaires for 144 students (110 males, 34 female) in Hongseung-located college. More exercise time and less frequency of alcoholic beverage they intake, lowered their body fat %. Males did stronger exercise and had lower body fat % than females. The stronger exercise they did, the lower body fat % they had, and were more satisfied with their present weight. Since they had more alcoholic beverage, they smoked more. Less smoking, more abdominal obesity they were. The less satisfaction with their body weights, the higher body fat % they had. The obese less were content with their weights. More recognition of obese shape, higher body fat % they had and abdominal obesity they were. Female had higher body fat % and were more abdominal obesity, did weak action, less smoke and weak exercise than male. Higher body fat % they had, more abdominal obesity they were. The more part time jobs they had, they did not smoke or were not satisfied with their body weights. Female students in culinary arts division had higher body fat % and were dissatisfied with their body weights and did less exercise or subnormal exercises.
