“…Aside from financial affordability, the literature also highlights the impact of unhealthy eating behaviors at the price of convenience or saved time. While consumption frequencies of fruits and vegetables has decreased [ 26 ], high energy and low nutrient foods (e.g. instant noodles, fried food, junk food) are more frequently consumed particularly among children, regardless of their income status [ 27 28 29 ].…”

Food deserts in Korea? A GIS analysis of food consumption patterns at sub-district level in Seoul using the KNHANES 2008-2012 data

BACKGROUND/OBJECTIVESThe concept of "food deserts" has been widely used in Western countries as a framework to identify areas with constrained access to fresh and nutritious foods, providing guidelines for targeted nutrition and public health programs. Unlike the vast amount of literature on food deserts in a Western context, only a few studies have addressed the concept in an East Asian context, and none of them have investigated spatial patterns of unhealthy food consumption from a South Korean perspective.SUBJECTS/METHODSWe first evaluated the applicability of food deserts in a Korean setting and identified four Korean-specific unhealthy food consumption indicators, including insufficient food consumption due to financial difficulty, limited consumption of fruits and vegetables, excessive consumption of junk food, and excessive consumption of instant noodles. The KNHANES 2008-2012 data in Seoul were analyzed with stratified sampling weights to understand the trends and basic characteristics of these eating patterns in each category. GIS analyses were then conducted for the data spatially aggregated at the sub-district level in order to create maps identifying areas of concern regarding each of these indicators and their combinations.RESULTSDespite significant reduction in the rate of food insufficiency due to financial difficulty, the rates of excessive consumption of unhealthy foods (junk food and instant noodles) as well as limited consumption of fruits and vegetables have increased or remained high. These patterns tend to be found among relatively younger and more educated groups, regardless of income status.CONCLUSIONSA GIS-based analysis demonstrated several hotspots as potential "food deserts" tailored to the Korean context based on the observed spatial patterns of undesirable food consumption. These findings could be used as a guide to prioritize areas for targeted intervention programs to facilitate healthy food consumption behaviors and thus improve nutrition and food-related health outcomes.

“…A possible reason for the low consumption of vegetables by adolescents is the current popularity of Western foods and food practices, involving an increased intake of processed foods and regular dining out, in Korea. Adolescents also prefer animal products or fast food over plant-based foods such as whole grains and vegetables [ 7 8 ]; thus, the implementation of nutrition intervention to encourage adolescents to increase their vegetable intake is needed.…”

BACKGROUND/OBJECTIVESDespite the importance of consuming sufficient amounts of vegetables, daily vegetable intake among adolescents in Korea is lower than the current dietary recommendation. The objective of this study was to examine determinants affecting vegetable preference in order to suggest a stage-tailored education strategy that can promote vegetable consumption in adolescents.SUBJECTS/METHODSAdolescents (n = 400, aged 16-17 years) from two high schools participated in a cross-sectional study. Survey variables were vegetable preference, the social cognitive theory (SCT) and stages of change (SOC) constructs. Based on vegetable preference, subjects were classified into two groups: a low-preference group (LPG) and a high-preference group (HPG). SOC was subdivided into pre-action and action/maintenance stages. To compare SCT components and SOC related to vegetable preference, chi-squared and t-tests, along with stepwise multiple-regression analysis, were applied.RESULTSIn the LPG, a similar number of subjects were classified into each stage. Significant differences in self-efficacy, affective attitudes, and vegetable accessibility at home and school were detected among the stages. Subjects in the HPG were mainly at the maintenance stage (81%), and there were significant differences among the stages regarding self-efficacy, affective attitudes, and parenting practice. In the predictions of vegetable preference, self-efficacy and parenting practice had a significant effect in the “pre-action” stage. In the action/maintenance stage, outcome expectation, affective attitudes, and vegetable accessibility at school had significant predictive value. In predicting the vegetable preference for all subjects, 42.8% of the predictive variance was accounted for by affective attitudes, self-efficacy, and vegetable accessibility at school.CONCLUSIONThe study revealed that different determinants affect adolescent vegetable preference in each stage. Self-efficacy and affective attitudes are important determinants affecting vegetable preference. Additionally, school-based nutrition intervention that focuses on enhancing affective attitudes, self-efficacy, and vegetable exposure may constitute an effective education strategy for promoting vegetable consumption among adolescents.

“…Numerous factors may influence the dietary behaviors of adolescents. On the other hand, biochemical, genetic, socio-cultural, and psychological factors affect the prevalence of obesity [5][6]. CDC (2014) points out that poor dietary behaviors such as eating of low-quality foods containing significant amount of salt, sugar, and fat and consumption of soft and carbonated drinks, as well as insufficient levels of exercise and stress are among the most important causes of obesity at younger ages [2].…”

On the other hand, fruit and vegetables (FV) help to reduce the risks for many illnesses such as cardiovascular diseases, diabetes, obesity, and some types of cancers [5][6][7]. Adolescents with high dietary self-efficacy perception levels consume lower fat and less sugary foods, as well as foods that are good for health promotion [8][9].…”

To predict demographic, psychosocial, and behavioral variables specific to each stage by determining the stages of change of dietary behaviors of adolescents within the framework of Transtheoretical Model (TTM) and thus to guide for interventions make adolescents ready f or next stage of change. A descriptive, cross-sectional design was used in the study. The students aged between 10-12 and selected indicators. Separate multivariate logistic regression models were created to determine the readiness of adolescents to make changes in dietary behaviors. Of the adolescences, 89.5% were in the Preparation, Action and Maintenance stages. In the Contemplation stage, f ather education and mother Body Mass Index (BMI); In Preparation, mother BMI, dietary knowledge and dietary self-efficacy; In Action, adolescent BMI, dietary knowledge and stress management were able to predict the later stage of promoting behavior change. In the Maintenance stage the sex, adolescent BMI, dietary knowledge, dietary behavior, dietary self-efficacy, stress management and social support were able to predict the maintenance of promoting health. TTM was useful to evaluate and predict health behaviors of adolescents. Except for exercise behavior, all of the determinants predicted the later stage for promoting behaviors. Female adolescents were more likely to be ready to make changes.
