This study was conducted to analyze diet and health-related factors based on the income level of single-adult households using data from the Korea National Health and Nutrition Survey (KNHANES). Among those who participated in the 2016–2018 KNHANES, 951 single-adult households aged 19 to 64 were selected, and factors such as general characteristics, physical characteristics, dietary behaviors, health behaviors, and the prevalence of chronic diseases were analyzed. The high-income group had higher frequency of eating out, better dietary status generally, higher recognition rate of nutrition labels than the other groups. The rate of alcohol consumption and smoking was higher in the high-income group of single-adult households, while the rates of anxiety and depression were higher in the low-income group. Additionally, the use of dietary supplements decreased as income level decreased. Among chronic diseases, hypertension, diabetes, and dyslipidemia had the lowest prevalence in the middle-income group and the highest prevalence in the low-income group. These results suggest that diet and health behaviors vary by income level in single-adult households and may be associated with the prevalence of chronic diseases. Future systematic studies should be conducted to determine the causal relationships between these factors.
This study analyzed the 2019 Community Health Survey data to compare and analyze the health levels and life satisfaction of single-person elderly households based on food security. The final study subjects were 15,606 single-person elderly individuals aged 65 and above. These subjects were classified based on their response to food security into three groups: food sufficient-diverse, food sufficient-not diverse, and food insufficient. The study results showed that the proportion of the food insufficient group among single-person elderly households was 7.4% for men and 10.6% for women, with a slightly higher rate for female elderly. Both male and female elderly over 80 years of age, with low education levels, and basic living support recipients showed significantly higher proportions in the sufficient-not diverse and food insufficient groups. For male elderly, significant differences were observed in subjective health status and oral health level in the food insufficient group, and for female elderly, stress levels also showed significant differences. Life satisfaction scores were generally lower for female elderly compared to male, and significant differences were found in both male and female elderly based on food security. Common factors that significantly influence life satisfaction among single-person elderly households, both male and female, include food security, subjective health status, and living environment satisfaction, with food security being the most impactful factor. The study suggests that it is necessary to include these significant factors in the development of various social activity programs, such as dietary programs, to enhance life satisfaction and food security of single-person elderly households.
