Development of Strategies to Improve the National Nutrition Survey System / 대한지역사회영양학회지

OBJECTIVES: The current survey environment is changing and participation rates in national nutrition surveys are decreasing. Therefore, the purpose of this study was to develop strategies for improving the nutrition survey system in the Korea National Health and Nutrition Examination Survey (KNHANES). METHODS: To develop an alternative system for conducting the KNHANES nutritional survey, we conducted focus group interviews with stakeholders of the survey, SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis, and expert reviews. In addition, spatial analysis of potential sites for conducting surveys instead of relying on household visits was performed, and the perception of nutritional surveys in the population eligible for KNHANES was evaluated. RESULTS: Based on the results of the focus group interviews, SWOT analysis, and expert reviews, we propose two options for survey sites: vehicles specifically prepared for nutritional surveys and public facilities such as community service centers or public health centers. Among public facilities, community service centers were found to be more appropriate sites than public health centers because they were considered more accessible. About 90% of respondents would participate in the survey in public facilities and about 74% would in vehicles. CONCLUSIONS: Conducting national nutrition surveys in specially designed vehicles and public facilities could be a viable alternative to home visits. Next, the validity of these newly proposed nutrition survey methods needs to be compared to the results of the current national nutrition survey.

Socio-demographic factors and diet-related characteristics of community-dwelling elderly individuals with dysphagia risk in South Korea

BACKGROUND/OBJECTIVES: The objective of this study was to determine dysphagia risk among community-dwelling elderly people living at home. We also examined the impact of socio-demographic variables on dysphagia risk as well as the relationship between dysphagia risk and dietary characteristics. SUBJECTS/METHODS: The study sample included 568 community-dwelling individuals, aged 65 years and above, who were living independently in their own home in Seoul, Gyeonggi, or Gwangju in South Korea. We used a dysphagia risk assessment scale to screen for dysphagia risk and the Mini nutritional assessment to evaluate the nutritional status. Associations between dysphagia risk and other variables were assessed using logistic regression analysis. RESULTS: Of the 568 subjects, 350 (61.6%) were classified into the dysphagia risk group (DR) and 218 (38.4%) were classified into the normal group (non-DR). Being female (odds ratio (OR) = 1.82, 95% confidence interval (CI) = 1.28–2.59), being 75 years and older (OR = 2.40, 95% CI = 1.69–3.42), having a lower education level (OR = 2.29, 95% CI = 1.33–3.97), and having a lower perceived economic status (OR = 2.18, 95% CI = 1.32–3.60) were more frequently observed with dysphagia risk compared to those who did not have such characteristics. Lowered mastication ability (OR = 14.40, 95% CI = 4.43–46.95), being at risk of malnutrition or malnourished (OR = 2.72, 95% CI = 1.75–4.23), lowered appetite (OR = 3.27, 95% CI = 2.16–4.93), and decreased food intake (OR = 2.95, 95% CI = 1.83–4.78) were observed more frequently in the DR group than in the non-DR group when adjusting for potential confounding factors. CONCLUSIONS: It is necessary to develop and apply integrated programs to improve the dietary habits and nutritional status of elderly individuals at risk for dysphagia, especially for women aged 75 years or older with lower educational and economic levels.
