Mealtimes with Parents vs. Mealtime Alone: Consequences for the U.S. Adolescents’ Behavior Problems and Depression

Association between having a meal together with family and smoking: a cross-sectional nationwide survey

BACKGROUND

Smoking is a major risk factor that significantly affects public health. Although the South Korean government spends significant money on smoking cessation services, the smoking rate remains stagnant. Families influence health-conscious decisions, and family meals can positively affect smoking suppression and health behaviors. Therefore, this study investigated whether family meals are correlated with adults' smoking behaviors.

METHODS

This study used data from the 2019-2021 Korean National Health and Nutrition Examination Survey. Having a meal together with family was defined as "yes" for those who have at least one meal with their family each day and "no" for those who do not. Current smoking status was classified as having smoked at least 5 packs of cigarettes (100 cigarettes) in one's lifetime and having used either conventional cigarettes or e-cigarettes in the last 30 days. Multiple logistic regression analyses were used to examine the association between eating together, smoking, and weight application.

RESULTS

When comparing the group that ate with their family compared to the group that did not, the odds ratio for current smoking status was 1.27 (95% confidence interval [CI]: 1.05-1.54) for male participants and 1.90 (95% CI: 1.33-2.71) for female participants. This showed a dose-dependent effect according to the frequency of family meals. Those who smoked conventional cigarettes had a strong association (men: OR 1.28, 95% CI 1.00-1.67; women: OR 2.22, 95% CI 1.42-3.46). However, those who only vaped e-cigarettes or used both conventional cigarettes and e-cigarettes had no statistically significant correlations.

CONCLUSION

This study provides evidence suggesting that eating meals as a family is related to smoking behavior and can positively affect smoking cessation intentions in adults. Consequently, a smoking cessation program can be developed that uses social support, such as encouraging family meals.

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.
