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.

This study aimed to compare adherence to dietary guidelines between elderly and non-elderly individuals with type 2 diabetes mellitus (T2DM) in Korea. Data of 4,577 participants with T2DM were collected from the 1998-2015 Korea National Health and Nutrition Examination Surveys. The participants were classified into two groups based on age: non-elderly T2DM group comprising participants aged 30–64 years and elderly T2DM group comprising participants aged ≥ 65 years. Adherence to dietary guidelines was assessed using the Korean Diabetes Association-Korean Ministry of Health and Welfare (KDA-KMHW) index, comprising six components of dietary guidelines for T2DM patients. Multivariable generalized linear regression analysis was performed to analyze the KDA-KMHW index scores. The adherence levels to the individual components of the KDA-KMHW index were mostly lower in non-elderly group (p < 0.001) than elderly group, except for moderate carbohydrate consumption. The total KDA-KMHW index score was significantly lower in non-elderly T2DM group than in the elderly T2DM group (p < 0.001). The study results suggest the need for developing patient-specific education programs that focus on adherence to dietary guidelines, particularly for non-elderly patients, to adequately intervene with the difficulties experienced in T2DM dietary management.
