Summary
Higher rates of eating out are linked to increased body mass index (BMI) and obesity risk in South Korean women. No significant association was found in men, highlighting a need for targeted obesity prevention education.
Area of Science:
- Nutrition Science
- Public Health
- Epidemiology
Background:
- Adult men tend to consume more calories when dining out compared to meals prepared at home.
- Understanding the relationship between eating-out frequency and weight status is crucial for public health initiatives.
Purpose of the Study:
- To investigate the association between the daily eating-out rate and body mass index (BMI) in the Korean population.
- To determine if this association differs between genders.
Main Methods:
- Utilized data from 18,019 Korean adults (aged ≥19) from the 2013-2016 Korea National Health and Nutrition Examination Survey (KNHANES).
- Assessed Body Mass Index (BMI) using Asia-Pacific criteria.
- Employed multinomial logistic regression analysis to examine the eating-out rate and BMI relationship.
Main Results:
- Women with higher daily eating-out rates showed significantly increased risks of being overweight and obese.
- Specifically, 1%-50% and 51%-100% eating-out rates correlated with higher odds of obesity and overweight in women.
- No statistically significant association between eating-out rate and BMI was observed in men.
Conclusions:
- The study identified a positive association between frequent eating out and higher BMI in South Korean women, but not men.
- Findings suggest a need for targeted health education on mindful eating habits to prevent obesity among women who frequently dine out.
- Public health strategies may need to consider gender-specific approaches to address diet-related health issues.

One of the core constructs in social psychology is the notion of an attitude toward an object or person. Traditionally, psychologists measured attitudes by simply asking people to self-report their beliefs, opinions, or feelings. This approach has limitations, however, when measuring socially sensitive attitudes, like racial prejudice, because people are often motivated to self-report unprejudiced, egalitarian beliefs (despite...

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Diagnosing eating disorders in healthcare is challenging. Therefore, the present protocol develops an algorithm based on 949 patient responses to a questionnaire, with the diagnosis displayed on an easy-to-use web-based interface. This system facilitates the accurate diagnosis of eating disorders while excluding those believed to have an eating disorder.
