Summary
Stress awareness and physical inactivity are linked to weight gain in women. These factors, along with skipping breakfast, significantly impact weight changes, unlike sleep duration or depression after adjustments.
Area of Science:
- Public Health
- Epidemiology
- Behavioral Science
Background:
- Investigating lifestyle factors contributing to weight gain is crucial for public health interventions.
- Understanding the differential impact of stress, depression, sleep, physical activity, and diet on weight is essential.
Purpose of the Study:
- To identify key factors associated with weight gain.
- To determine which lifestyle factors (stress, depression, sleep, physical activity, diet) have a greater impact on weight gain.
Main Methods:
- Utilized data from the 2016 Korea National Health and Nutrition Examination Survey (KNHANES VII).
- Included 3,163 adults (19-64 years), excluding those with weight-affecting diseases.
- Employed t-tests, chi-square tests, and logistic regression to analyze associations and odds ratios (ORs).
Main Results:
- Weight gain group participants were younger and more likely to be obese.
- Among women, stress awareness (OR: 1.27), physical inactivity (OR: 1.25), and skipping breakfast (OR: 1.28) were significant predictors of weight gain.
- Depression showed an association with weight gain in women, but this was not significant after adjusting for other variables. No significant associations were found for men.
Conclusions:
- Stress awareness is a significant factor associated with weight gain in women.
- Psychological factors like depression and sleep duration did not show a significant association with weight gain after adjustments.
- Physical inactivity and dietary habits (skipping breakfast) are important considerations for weight management in women.
