Abstract

Relationship between nutritional status and cardiovascular health according to the household type of adults in Korea : Using the 7th~8th (2016~2019) Korea National Health and Nutrition Examination Survey Park Yoon-Seon Advisor : Prof. Choi, Ji-Young, Ph. D. Major in Nutrition Education Graduate School of Education, Chosun University Due to the rapid increase in single-person households, the change from the type of household that makes up a large family in the past to the type of household centered on the nuclear family is being made, and it is believed that it may negatively affect cardiovascular health in relation to the fact that single-person households have poor intake of various nutrients and subjective health compared to households with two or more people. However, there are currently insufficient cases of studying the relationship between nutritional status and cardiovascular health by classifying household types. Therefore, this study aims to ascertain whether a relationship exists between the characteristics of nutritional status and cardiovascular health, contingent on the type of adult household in Korea. This study was conducted based on the cross-sectional study design using the raw data of the 7th-8th National Health and Nutrition Survey (2016-2019). The subjects of this study used data collected from a total of 8,231 adults, excluding those who met the exclusion criteria among adults aged 30 to 69 living in Korea. Cardiovascular health is an index that scores the risk factors for cardiovascular disease by the sum of the risk levels, and seven risk factors for cardiovascular disease (systolic blood pressure, diastolic blood pressure, abdominal obesity, diabetes, high triglycerideemia, low high-density lipoprotein cholesterol, and high total cholesterol were converted into z-scores and summed up as standard indicators for cardiovascular health. Data analysis was designed as a complex sample analysis applying stratification variables, colony variables, and weights through the IBM SPSS Statistics 25 program and analyzed by frequency analysis, t-test, variance analysis, and multiple regression analysis. As a result of the study, among the general characteristics of the study subjects, the age distribution was found to be relatively high in single-person households in their 30s and 60s, and high rates in their 40s and 50s in two-person households. In terms of income level, single-person households were lower than two-person households. Among the total participants, the rate of skipping meals for each meal was breakfast (32.6%), lunch (9.6%), and dinner (7.3%) in single-person households, and breakfast (23.3%), lunch (6.6%), and dinner (4.6%) in two-person households were found to have a higher rate of skipping meals in single-person households, and the frequency of eating out was also higher in single-person households in the number of eating out. Nutrient intake analysis highlighted that households with two or more occupants demonstrated elevated intake levels of dietary fiber and vitamin C. Notably, dietary fiber intake was found to exert a significant influence on cardiovascular health standard indicators (CVH). Examining the characteristics of cardiovascular risk factors, single-person households generally exhibited worse outcomes compared with two or more person households. Specifically, higher levels of systolic blood pressure, diastolic blood pressure, waist circumference, fasting blood sugar, total cholesterol, and triglycerides were observed in single-person households compared to households with two or more occupants. In conclusion, there is a imperative need for sustained observation and research pertaining to the nutritional status and cardiovascular health of diverse household types among Korean adults. Furthermore, the implementation of diverse nutrition education measures is essential to mitigate the prevalence of dietary deficiencies and should be tailored to the specific characteristics of different household types to ensure the equitable consumption of various nutrients. Additionally, it is considered crucial to develop an educational program that customizes preventive cardiovascular disease education and healthcare education to minimize complications based on specific household types for enhanced cardiovascular health outcomes.
