This study aimed to investigate the relationship between meal regularity (i.e. breakfast intake and meal-times), and the risk of metabolic syndrome (MetS) among generally healthy Korean single-person household adults (≤60 years, n=594) based on the Seventh Korean National Health Examination and Nutrition Survey (KNHANES) (2016~2018). Among men (n=325), the breakfast intake frequency was not significantly associated with the pervalence of MetS. However, men consuming a regular meal at least once a day showed a lower prevalence of MetS compared to those whose meals were irregular. These patterns remained after adjusting for age, smoking and drinking habits, individual income, education level, exercise, and total calorie intake. An association between meal regularity and MetS risk was observed in post-menopausal women (n=84), but not in pre-menopausal women (n=185). More specifically post-menopausal women with irregular breakfast eating habits or eating no breakfast at all showed a significantly higher risk of MetS than those eating breakfast regularly after the adjustment. The analysis revealed an odds ratio (OR) of 8.46, confidence intervals (CIs): 1.149~62.199, P<0.05 in irregular breakfast eaters, and an OR of 13.377, CIs: 1.665~107.511, P<0.05, in those who ate no breakfast. Furthermore, post-menopausal women who had irregular meals daily showed a higher risk of MetS than those consuming one or more regular meals/day after the adjustment (OR: 16.888, CIs: 1.258~226.655, P<0.05). In conclusion, the results from this study may be used for formulating optimal dietary guidelines for the prevention and the management of MetS in adults in single-person households.

The purpose of this study is to prevent obesity in the elderly and to seek differentiated intervention measures according to education level by comparing and analyzing the factors influencing obesity in single-person households according to education level. Using the data from the National Health and Nutrition Survey in 2020, cross-analysis and logistic regression analysis were conducted through data of a total of 400 respondents, and the analysis showed vulnerability in physical activities that could affect obesity if the education level was low, and risk factors such as eating out and sodium intake were high. As a result of comparative analysis of influencing factors through the classification of education levels, sedentary time was a risk factor in the low-education group, and sodium intake was a risk factor for obesity in the high-education group. Through this, it was discussed the need for healthy nutrition and physical activity education for middle-aged and elderly single-person households, and differentiated intervention according to the level of education.

The purpose of this study was to analyze the relationship between social participation activities, cognitive function, and depression of middle and old single-person households in consideration of social problems such as aging population and increasing single-person households. For the analysis, path analysis and multi-group analysis were conducted. As a result of the analysis, it was found that social participation activities of middle and old single-person households reduced depression through increased cognitive function, and the positive effects of social participation activities were stronger in groups of dementia. Based on these results, we discussed ways to promote social participation activities, implications for developing programs that can help cognitive function or mental health, and suggested the need for programs or treatment methods to promote social participation rather than isolated treatment in nursing facilities.

This study utilized the data from 2017, 2019 Korean National Health and Nutrition Survey to analyze the factors influencing depression and suicidal ideation among single-person households. For the analysis, demographic and economic variables as well as health status/behavior variables were considered. Activity restriction (OR: 4.753, p-value: <.0001) and smoking status (OR: 2.013, p-value: 0.044) were significantly associated with depression, and in terms of suicidal ideation, household income (OR: 3.526, p-value: 0.043), subjective health status (OR: 2.945, p-value: 0.007), activity restriction (OR: 2.263, p-value: 0.003) and smoking status (OR: 2.000, p-value: 0.023) showed significant association. In this regard, single-person households are likely to experience psychological angst, and further experience mental problems due to socio-economic and physical crisis. Therefore, it is necessary to establish a social network system in the community to detect those in need and provide appropriate interventions to prevent harmful outcomes.

This study was conducted to compare of dietary behaviors of young and temporary workers with older and permanent workers of single-person households. A questionnaire survey was conducted by purposive quota sampling(n=566) by age groups(20~59 years old) and status of workers(temporary workers, permanent workers and business owners). Compared to other age groups, 20s had lower average monthly income and cost of eating-out, and they rarely cooked at home and mainly bought food and groceries at convenience stores(p<0.001). This pattern was similar to temporary workers compare to other groups. This study will be meaningful as a basic data for creating a healthy living environment for temporary workers and 20s of single-person households.

To comparison of the differences in affecting factors of prevalence of obesity and hypertension according to the employment type of single-person households, aged 20 to 59 years old people were classified by permanent and temporary workers(n=566). A questionnaire survey was conducted by purposive quota sampling to ask disease, income and health habits. In the results of logistic regression on hypertension and obesity, the prevalence of hypertension was significantly affected as age and obesity increased regardless of employment type. In particular, temporary workers with lower income were more likely to have hypertension(p<0.001). The prevalence of obesity was significantly lower for female than for male regardless of employment type. In particular, temporary workers had a higher prevalence of obesity as their dinner fidelity decreased(p<0.001). As a result, chronic disease management for single-person households with lower income and dinner fidelity should be intervened in more useful ways.

Purpose: This study focused on the societal changes associated with the entry into an ultra-aged society and the increase in single-person households. The core objective of this research is to investigate how social intelligent robots can bring about positive changes in the lives of individuals in single-person households and how such changes influence user satisfaction and the intention to use these robots. Methods: The study employed a cross-sectional analysis using a structural equation model. A survey designed to assess the impact of social intelligent robots' characteristics, such as perceived encouragement, empathy, presence, appearance, and attachment, on user satisfaction and usage intentions was conducted. Data were collected from a total of 335 users and analyzed using the structural equation model. Results: In the characteristics of social intelligent robots for single-person households, it was found that empathy, presence, and attachment significantly influenced satisfaction, while perceived encouragement, empathy, and attachment significantly influenced usage intentions. The research results indicate differences between enhancing user satisfaction and increasing the intention to use social intelligent robots. The findings suggest the essential need for a user-centric approach in the design and development of social intelligent robots. Additionally, it was observed that emotional support plays a crucial role in users' experiences with social intelligent robots. Conclusion: This study verified the impact of social intelligent robots on satisfaction and usage intentions based on users' experiences. It examined the influence of linguistic, visual, and personal characteristics of robots on user experiences, providing insights into how technological and human aspects of social intelligent robots interact to shape user satisfaction and usage intentions. Consequently, the study confirmed that social intelligent robots can bring positive changes to human life, emphasizing the necessity for the advancement of robot technology in a human-centric direction.

Focusing on increasing of single-person households this study aims to develop a scale to measure the healthiness of lifestyle among single-person households. The concept of healthiness of lifestyle is based on the theories of family strength and family ecology. We draw 50 items that encompass basic needs, individual, familial, and social aspects of single-person life. Using a sample of 317 persons who live alone, this study examined a factor structure of the items and selected 44 items based on the results of factor analysis. Reliability and criterion- and construct validity were also examined. The final scale consists of four domains; basic needs (finance, housing, consumption, and future plan), work·life balance (time management, health, and stress), family relations, and social participation (social network, social interests, and community participation). This scale can be used as an assessment measure of the healthiness of lifestyle of single persons who participate in programs in Healthy and Multicultural Families Support Centers.

This study sought to analyze factors influencing high-risk drinking in single-person households. For this, data from the 2018 community health survey were used. Subjects were 32,389 adults above the age of 19 in single-person households. For the data analysis, high-risk drinking groups were extracted according to the high-risk drinking rate index of the survey to arrive at influencing factors and differences in health-related and sociodemographic characteristics. The IBM SPSS 25.0 software was used for analysis and a complex sampling design was applied. The results showed that the high-risk drinking rate of Korea's single-person households was 15.0% (male: 25.8%, female: 5.8%) and age, education under high school level, service-industry employees, smokers, people with depression, high blood pressure, and irregular breakfast eaters appeared as common elements for both genders. Stress appeared to only affect males while being diabetic only affected females. High-risk drinking was higher for males in their 30~40s and women in their 20~30s. The younger generation showed the highest numbers in high-risk drinking and factors like stress or depression appeared to be influencing factors for high-risk drinking. Hence, mental health programs along with customized health policies through health forms and lifestyle changes will be required to lower the high-risk drinking rates of single-person households.

Background: This study aimed at investigating the meal regularity, health, and oral health habits of single Korean households to understand the impact of these factors on the risk of metabolic syndrome, in addition to preventing and managing metabolic syndrome. Methods: Using raw data from the 8th Korea National Health and Nutrition Examination Survey (2019), 274 study subjects, aged 19 to 64, were selected primarily from single adult households. Complex sample statistical analysis was performed using the Predictive Analytics Software Statistics ver. 18.0 program. Results: Regarding the meal regularity in single-person households in Korea, the younger group outperformed the middle-aged group, and those who drank more than once a month performed better than those who drank less than once a month. In terms of oral health, regardless of the age and the income level, participants who ate three meals a day had a higher rate of speech problems and chewing difficulties than those who ate irregularly or regularly on a regular day. Factors influencing the risk of developing metabolic syndrome were age, speech problems, and frequency of toothbrushing. Compared to the younger group, there were 0.361 times more people in the middle-aged group; and compared to those without speech problems, there were 1.161 more people with speech problem. Compared to those who tooth brushed more than four times a day, there were 1.284 more people who tooth brushed 2 to 3 times a day and there were 5.673 times more people who tooth brushed less than once. Conclusion: Based on the study results, it is necessary to implement a program that can plan and apply customized management measures and prevent metabolic syndrome by improving and correcting the health and oral health behaviors of single-person households in Korea. Therefore, active mediation measures, such as support and publicity at the local or national level, should be planned.
