Spatial, temporal, and health associations of eating alone: A cross-cultural analysis of young adults in urban Australia and Japan

Trust and distrust in food among non-dependent elderly people in Spain. Study on socio-cultural representations through the analysis of cultural domains

The social and cultural representations of food are essential when it comes to understanding the perception of risk and the trust/distrust that people place on it. In this paper, we analyse the attributes and categories that non-dependent older people aged 65 and over living in Spain use when talking about trust/distrust in relation to food. In order to explore how they manifest different social meanings, we have conducted a study based on an analysis of cultural domains. The results of examining free-listing and pile-sort techniques were triangulated with the narratives obtained from interviews, life histories, food diaries and participatory workshops. The ethnographic research was conducted between June 2021 and June 2022 in the autonomous communities of Andalusia and Catalonia as well as the Valencian Community. Understanding the criteria for trust and distrust through the analysis of cultural domains allows us to better comprehend what food risks are perceived by older people and what value they place on food safety in their food choices. This study aims to provide qualified input for the development of healthier eating habits with recommendations for making ageing an easier process.

Socio-cognitive barriers to healthy eating among mothers: A segmentation analysis in Argentina, France, and Denmark

The prevalence of childhood obesity has increased at an alarming rate despite several actions to reverse this trend. It is important to focus on tackling the constraints for healthy food provisioning. We focus on identifying segments of mothers in relation to factors acting as barriers to healthy eating. Five hundred mothers in each country (Argentina, France and Denmark) completed an online survey. In each of the three countries, four segments are identified, varying mostly on working and socio-economic status, self-efficacy and attitudes to health experts. Segments of mothers who are skeptical to nutrition advice from health professionals were identified. Another important finding is that staying-at-home mothers might face more barriers to healthy eating than mothers who work outside the home. We provide suggestions for targeted interventions addressing healthy eating behaviors among mothers with different profiles.

Parenthood as a Window of Opportunity for Dietary Changes: Perspectives From Uruguayan Parents

Research on behavioral and social science has demonstrated that transitions throughout a person's life course, as the life event of becoming a parent, represent an opportunity for dietary changes. However, research in this area has been mostly restricted to developed European and North American countries and has shown ambiguous results. The present work aimed to gain an in-depth understanding on the changes in eating habits caused by the transition to parenthood and to explore factors influencing those changes in Uruguay, a Latin American country. Forty-two in-depth interviews with Uruguayan parents from diverse social-economic backgrounds were conducted. The narrations by the interviewees evidenced mostly positive changes during three stages in the transition: pregnancy, the first months with the baby, and the beginning of complementary feeding. Most informants perceived changes mainly in terms of increased consumption of fruits, vegetables, and pulses; increased consumption of homemade meals; and decreased consumption of ultra-processed foods, fast foods, and fried foods. Reasons for these changes included adaptation of meals to the child's needs and schedule, feeling of responsibility for the child's health, and willingness to be a good role model. Factors influencing changes in eating habits were identified in some levels of the socioecological model and included socioeconomic status; price of fruits, vegetables, and fish; low accessibility of good quality fish; perceived time pressure; father's low interest on healthy eating; social support; and access to nutrition information. Findings suggest that parenthood represents a window of opportunity for favorable changes in eating habits. However, barriers constraining those changes should be addressed by stakeholders.

Association between meal frequency with others and psychological distress during the COVID-19 pandemic: A cross-sectional study

Aim

Previous studies evaluated the association between eating alone and mental health mainly in older people and adolescents. This study aimed to evaluate the association between dinner frequency with others and psychological distress during the COVID-19 outbreak among the Japanese working population.

Methods

Data were acquired from a prospective online cohort study (the Employee Cohort Study in the COVID-19 pandemic in Japan) conducted in February 2021 as a cross-sectional design. Dinner frequency with others was categorized into five groups: "almost daily," "4-5 times per week," "2-3 times per week," "once per week," and "less than once per week," setting them as a predictor variable. Modified Poisson regression was performed to calculate the prevalence ratio of psychological distress with multiple imputation for missing data. Global fear and worry about COVID-19 were adjusted as a covariate.

Results

A total of 1171 participants completed the questionnaire. Respondents who ate dinner with others "almost daily" had the least psychological distress than those who ate with others "4-5 times," "2-3 times," and "once per week" in the crude model (prevalence ratio (95% CI): 1 [reference], 1.34 [1.08-1.67], 1.40 [1.15-1.69], 1.44 [1.12-1.85], respectively). The association was comparable after adjusting for global fear and worry about COVID-19.

Conclusions

Among those who ate dinner with others at least once a week, those who ate with others "almost daily" had the least psychological distress. The association was comparable after adjusting for global fear and worry about COVID-19. Further study is needed on why those who eat with others less than once a week may have a lower prevalence ratio of having mental distress.

Solo Dining at Home in the Company of ICT Devices

The consumption of a solo meal is often subject to negative associations. Studies indicate that solo diners use information and communication technology (ICT) devices such as smartphones, to mitigate negative experiences such as boredom and loneliness, especially when dining in a public context. However, we know less about the motivation to use such devices and consequent meal experiences in a private context. For this exploratory qualitative study, we asked participants to fill out a cultural probe kit to capture their dining experience and use of ICT devices over a period of seven days. Once completed, the content was discussed with participants during a semi-structured interview. Data was analyzed using thematic analysis in a deductive and inductive form leading to four themes: (1) The experience of eating with others; (2) The use of electronic devices while eating; (3) The meaning of food; and (4) Relaxing features and influences. Participants indicated that eating alone can be a pleasurable experience that people enjoy and perceive as relaxing. ICT devices were named to play an essential part in the dining experience. The entertainment that devices provide can mitigate feelings of loneliness and uncomfortable silence when eating by oneself. We reflect on the findings and point out potential design avenues for future studies.

Living and eating alone on depressive symptoms by physical frailty status: A cross-sectional study based on the Korean Frailty and Aging Cohort Study

BACKGROUND

General health conditions in older adults, including their mental health, differ greatly based on their physical health conditions rather than age. Thus, we evaluated how lifestyle factors, which included eating and living, affected depressive symptoms in older adults based on their physical frailty status.

METHODS

We included older adults aged 70-84 years from the Korean Frailty and Aging Cohort Study (KFACS). Based on their eating and living patterns, we classified them into four groups: "lived and ate with others," "lived alone yet ate with others," "lived with others yet ate alone," and "lived and ate alone." Depressive symptoms and physical frailty were measured using the Korean version of the Geriatric Depression Scale and modified version of the Cardiovascular Health Study (CHS) Frailty Index, respectively.

RESULTS

A total of 2,702 participants, 11.4% lived with others yet ate alone, and 19.7% lived and ate alone. For robust older adults, after adjusting for variables, the "ate alone" group was significantly related with depressive symptoms, and the "lived and ate alone" group showed a higher risk of depressive symptoms. In the prefrail to frail participants, the "lived and ate alone" group was at a higher risk of depressive symptoms.

CONCLUSION

Eating and living alone are key risk factors for depressive symptoms in community-dwelling older adults regardless of their physical frailty status. Therefore, social interventions are needed for both physically frail and healthy older adults to support their eating patterns and increase opportunities for social interaction.

Cloud-Based Commensality: Enjoy the Company of Co-diners Without Social Facilitation of Eating

Previous research has associated frequently enforced solo dining with negative consequences on psychological well-being, but the problem of having to eat alone may be solved by seeking mealtime companions in the digital space by watching an eating broadcast (i.e., Mukbang) or videoconferencing with others (i.e., cloud-based commensality). We conducted the present study to compare the consequences of Mukbang-based, cloud-based, and in-person commensality. Ninety-five healthy Chinese young adults were instructed to rate images of eating scenarios and foods. The results revealed that they expected loneliness to be reduced by Mukbang-based or in-person commensality, but they were also aware of the risks of enhancing food intake and/or being shifted toward less healthy food choices in these two scenarios. By contrast, the participants expected cloud-based commensality to provide the benefits of reducing loneliness without the health-compromising risks of increasing food intake or unhealthy eating. Collectively, these findings suggest the beliefs of the participants that cloud-based commensality can provide an "alone but together" context to balance the need for social interactions with the strategic avoidance of a social context facilitating unhealthy eating. The findings also provide some novel insights into how the application of technologies for eating behavior can be used to integrate social factors and food pleasure, and shed light on the promising future of cloud-based commensality as a combination of the strengths of solitary and commensal eating.

Associations among Solo Dining, Self-Determined Solitude, and Depression in South Korean University Students: A Cross-Sectional Study

Although solo dining motivated by self-determined solitude can be a positive and healthy experience for individuals, solo dining that is not motivated by self-determined solitude can trigger physical and mental health problems. This study examined the associations among solo dining, self-determined solitude, and depression in university students. Accordingly, an online survey was conducted on 372 university students. The results show that students who live alone, those in poor health, and those with more frequent solo dining experiences had higher depression scores than others. Whereas satisfaction with solo dining was high when voluntary solitude was high, female students displayed higher depression scores when they had low self-determined solitude or high non-self-determined solitude, and when they had a higher frequency of eating lunch alone, compared to their male counterparts. University undergraduates who live and dine alone, owing to non-self-determined solitude, are highly vulnerable to mental health problems, including depression. Hence, interventions that foster social connectedness and entail the identification of factors accounting for students’ non-self-determined solitude should be developed.

The use of ICT devices as part of the solo eating experience

An increasing number of people tend to eat alone due to social changes and an altered attitude towards cooking and eating practices. Anecdotal reports indicate that solo diners tend to use information and communication technology devices, for example, the smartphone, as part of the eating experience. While lab studies suggest that the devices contribute to an increased high-calorie food intake and decreased feeling of satiety, these studies disregard the everyday experience and motivation of solo diners. We conducted an exploratory study to investigate how solo diners use digital devices as part of their daily eating experience. Semi-structured interviews with solo diners (N = 12) were analyzed using thematic analysis in an inductive approach leading to six themes. The themes focus on (1) the perception of a meal; (2) the experience of a solo diner; (3) the purpose of using an information and communication technology device; (4) the perceived influence of the devices; (5) factors decreasing and increasing the use; (6) and the potential to promote healthier food consumption. Our results indicate that the use of digital devices while eating alone can lead to distraction, being unaware of the food texture and the amount that is eaten. The devices can also induce a positive influence by providing entertainment and mitigating negative emotions like loneliness and boredom. The devices have the potential to contribute to healthy eating practices by providing education and by influencing the speed of eating through elements of sound. Although the use of devices might negatively affect eating behavior, their ubiquitous presence also offers the opportunity to reach specific, vulnerable populations.

Association between commensality with depression and suicidal ideation of Korean adults: the sixth and seventh Korean National Health and Nutrition Examination Survey, 2013, 2015, 2017

OBJECTIVES

This study investigated whether commensality (eating a meal with others) is associated with mental health (depression, suicidal ideation) in Korean adults over 19 years old.

METHODS

Our study employed data from the sixth and seventh Korea National Health and Nutritional Examination Surveys (KNHANES) for 2013, 2015, and 2017. The study population consisted of 14,125 Korean adults (5854 men and 8271 women). In this cross-sectional study, data were analyzed with the Rao-Scott chi-square test and multiple logistic regression to evaluate the association between commensality(0[includes skipping meals] to 3 times eating meals together) and both depression and suicidal ideation using select questions from the Mental Health Survey. By setting socioeconomic factors, health conditions, and behavioral factors as confounders, we conducted a subgroup analysis to reveal the effect on depression and suicidal ideation commensality.

RESULTS

Commensality was significantly associated with depression and suicidal ideation (p < 0.05). In both sexes, people who ate fewer meals together had poorer mental health. In a subgroup analysis, we revealed greater odds of developing depression in men when living in rural areas and belonging to low-income groups. In contrast, greater odds of suicidal ideation in men who ate alone when living in the city and belonging to high-income groups. On the other hand, Women in every region had greater odds of being depressed if they ate alone. And greater odds of suicidal ideation in women who ate alone when living in the city and belonging to medium-high income groups.

CONCLUSIONS

Our analysis confirmed that Korean adults with lower chance of commensality had greater risk of developing depression and suicidal ideation. And it could be affected by individuals' various backgrounds including socioeconomic status. As a result, to help people with depression and prevent a suicidal attempt, this study will be baseline research for social workers, educators and also policy developers to be aware of the importance of eating together.

Characteristics of Eating Alone Affecting the Stress, Depression, and Suicidal Ideation

This study aimed to identify the characteristics of eating alone that influence stress, depression, and suicidal ideation in Korean adults. This study was a cross-sectional survey using the raw data of the sixth Korea National Health and Nutrition Examination Survey (KNHANES VI) conducted in 2015. The survey sampled 7380 adults, of whom 3515 were included in this analysis. The odds of stress were 1.308 times higher in individuals who ate dinner alone than those who ate dinner with others. The odds of having depressive symptoms were 1.711 times and 1.531 times higher in individuals who ate lunch and dinner alone, respectively, than those who ate lunch or dinner with others. The association between eating alone and suicidal ideation was statistically significant only in the simple model. There is a need for interventional programs that can reduce negative relationships of eating alone behaviors for preventing mental health problems.

Eating Alone at Each Meal and Associated Health Status among Community-Dwelling Japanese Elderly Living with Others: A Cross-Sectional Analysis of the KAGUYA Study

This cross-sectional study investigated the association between eating alone at each meal and health status, including functional capacity among community-dwelling Japanese elderly living with others. A self-administered questionnaire was mailed to all 8004 residents aged 65 or older, residing in the same Japanese town in March 2016. Eating alone was assessed by first asking whether participants ate three separate meals each day (i.e., breakfast, lunch, and dinner), and those who answered affirmatively were then asked how many people were usually present at each meal. Health status was assessed in terms of subjective health, medical history, care needs, body mass index, depression, and functional capacity. Data from 2809 respondents were analyzed. Those who reported not being in good subjective health and a history of hypertension were significantly more likely to eat alone at breakfast (odds ratio 1.27; 95% confidence interval 1.01–1.61, and 1.26; 1.06–1.49). Depressive symptoms and many subscales of functional capacity were also significantly associated with eating alone at breakfast, lunch, and dinner (p < 0.05). Many health status indicators were related to eating alone at each meal, especially breakfast.

Solo dining in Chinese restaurants: A mixed-method study in Macao

Given the emergence of solo dining resulting from the changing family structure and increasingly individualised lifestyle in contemporary Chinese society, this study investigates solo dining in the setting of Chinese restaurants in Macao, including the solo dining motivations, behavioural characteristics, and experiences, taking into considerations the underlying social and cultural factors. Adopting a sequential exploratory mixed-method design, 18 interviews were conducted, followed by a survey with 493 local diners. Findings show that freedom of choice and satisfying hunger are the main motivations for solo dining, and some solo-friendly attributes, food-related attributes, and restaurant characteristics are considered as important elements. Solo dining is perceived positively, partly because its perceptions and experiences are shaped by the diners' socio-cultural backgrounds and unique regional characteristics, in which solo dining is considered relatively common in Macao as opposed to extant literature that has suggested an essentialised assumption about Chinese group-oriented dining preference. Sociocultural insights and managerial implications are provided in catering to the growing solo diner market.

Eating Together and Health-Related Quality of Life Among Korean Adults

OBJECTIVE

To investigate the association between frequency of eating together and health-related quality of life (HRQoL).

DESIGN

Population-based cross-sectional study.

PARTICIPANTS AND SETTING

A total of 13,920 adults (≥19 years). Data obtained from the Korea National Health and Nutrition Examination Survey conducted from 2014 to 2016. The European Quality of Life-5 Dimensions index was used to assess the HRQoL.

MAIN OUTCOME MEASURES

Relation between the frequency of eating together (eating alone, 1 time/d, and ≥2 times/d) and HRQoL.

ANALYSIS

ANOVA, correlations, and multivariable logistic regression.

RESULTS

A significantly positive association was observed between the frequency of eating together and the European Quality of Life-5 Dimensions index (P < .001). An increase in the frequency of eating together was associated with decreased odds ratios of having problems in subdimensions (self-care, usual activities, and anxiety or depression; P for trend <.005).

CONCLUSIONS AND IMPLICATIONS

A decreased frequency of eating together is associated with low HRQoL. Additional work is warranted to confirm the association between the frequency of eating together and HRQoL in young adults, aged 19-64 years. Further studies are required to identify whether an intervention to increase the frequency of eating together would improve HRQoL in individuals who usually eat alone.

Associations of eating alone with type D personality, depression and rejection sensitivity among South Korean university students

PURPOSE

To identify the associations of eating alone with type D personality, depression, and rejection sensitivity among South Korean university students.

DESIGN AND METHODS

Data were collected from 370 students recruited from five universities using a self-reported questionnaire.

FINDINGS

Eating alone had significant correlations with type D personality and depression. Significant factors affecting eating alone were age, place of residence, type D personality, and depression. These factors accounted for 17% in eating alone.

IMPLICATIONS FOR NURSING PRACTICE

There is a need for interventional programs that can reduce the negative effects of eating alone and prevent depression among students with type D personality.

A question of food intake: The impact of living arrangement and meal factors on total daily caloric intake

There has been dramatic weight gain among college students during their collegiate years. A food diary can give much insight of a college student's life. The purpose of this study is to analyze the food intake of college-aged students taking in factors such as the size of meal, the foods being eaten, the location of the meal, and if the meal was eaten with others. The results of this study suggest that being male, eating breakfast, and eating more snacks relative to the number meals increases daily caloric intake. On the other hand, being female and eating more meals at home will result in a lower daily caloric intake.

Analysis of differences in eating alone attitude of Koreans by dietary habits and age

This study compares differences in eating alone attitude according to dietary habits and age in Seoul and Gyeonggi-do region in South Korea. Out of total 411 participants, 207(50.4%) were males and 204(49.6%) were females. 30 types of eating alone attitude were identified to perform a factor analysis; further these 30 types of attitudes were categorized into 8 factors termed as: 'enjoyable eating alone', 'eating alone as a daily routine', 'healthy eating alone', 'self-conscious eating alone', 'choose what I want', 'efficient eating alone', 'lonely eating alone', and 'solo dining'. Our investigation on the link between dietary habits and eating alone attitude revealed significant differences in 3 factors out of those 8 factors: healthy eating alone, solo dining, eating alone as a daily routine. The high healthy meal group was found to have less frequency of eating alone. Among people in their 20s and 30s, the low healthy meal group had more population than the high healthy meal group. There was a tendency that the population of the high healthy meal group increases as age rises. Our data indicated that the younger generation eats alone more frequently as a daily routine (p < 0.01), feels freer when eating alone, eats out alone more frequently (p < 0.01). People in their 20s were found to be more positive on eating alone and tended to be willing solo diners. The high healthy meal group did eat alone in a healthy way whereas the low healthy meal group had a negative view on eating alone. Our study aims at providing a good starting point to develop programs for healthy eating alone by finding gaps between healthy and unhealthy eating alone.

Eating Alone is Differentially Associated with the Risk of Metabolic Syndrome in Korean Men and Women

Few studies have examined overall patterns of eating alone in relation to the risk of metabolic syndrome (MetS) in Korean populations. The present study aimed to examine the relationship between patterns of eating alone and the risk of MetS in Korean adults. Data from the Korea National Health and Nutrition Examination Survey (KNHANES) for 2013–2015 were used, with 8988 Korean adult participants, including 3624 men and 5364 women, aged 18 to 64 years. Patterns of eating alone were categorized into eight groups based on the total frequency of eating alone on a daily basis in the past one year: (1) three times for breakfast, lunch, and dinner; (2) twice for breakfast and dinner; (3) twice for lunch and dinner; (4) twice for breakfast and lunch; (5) once for breakfast only; (6) once for lunch only; (7) once for dinner only; and (8) never eating alone. The presence of MetS has been defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) and International Diabetes Federation (IDF). Multivariable logistic regression analyses were performed to assess the association between patterns of eating alone versus the risk of MetS after controlling for age, income, occupation, number of family members, generation types, marital status, smoking status, and physical activity. The prevalence of MetS was the highest in men and women aged 40–64 who had breakfast, lunch, and dinner alone (50.1% and 36.8%, respectively). Men who had dinner alone or lunch and dinner alone compared with those who eat with others had a significantly higher risk of MetS, with adjusted odds ratios (AOR) of 1.51, and a 95% confidence interval (CI) of 1.06–2.16; and an AOR of 1.54, with a 95% CI of 1.05–2.25, respectively. Women who had breakfast alone compared with those who ate with others had a significantly lower risk of MetS (AOR 0.70, 95% CI 0.53–0.94). In conclusion, patterns of eating alone are differentially associated with the risk of MetS in a representative sample of Korean adults. Future studies are warranted to identify dietary patterns across the different eating alone patterns in relation to various health outcomes in Korean adult populations.

Who eats with family and how often? Household members and work styles influence frequency of family meals in urban Japan

Family commensality, or meals eaten together with family members, is a key practice to understand the socio-cultural organization of eating and family lives. Yet empirical evidence is limited outside of western societies, which have different household structures, work styles, and socio-cultural constructions of the practice. This study examined frequencies of family commensality based on 242 surveys of Japanese adults aged between 20 and 85 in two metropolitan areas. Results showed that family commensality is less frequent not only among those living alone, but also among those living with only non-partners including adult children, parents, and non-family members, than among those living with partners. Full-time employment was associated with late dinner times on weekdays. Later weekday dinner times were strongly associated with reduced frequency of dinners together. Late dinners have become commonplace among full-time workers in postwar Japan, and the peak dinner time in Japan occurs later than in other developed countries. Thus, work and lifestyle constraints impacting schedules appear to influence the frequency of family commensality. Our results suggest that frequencies of family commensality are influenced by co-residents and work styles of participants rather than household sizes. The idea that reduction of household size drives reduction of family commensality may be biased by previous studies conducted in western countries where most people reside in either single or nuclear households. Our study highlights complex determinants of family commensality, beyond presence of other household members, and demonstrates a need for rigorous investigation of family commensality across cultures.
