Background: As individual lifestyles become busier, people tend to skip breakfast more often than in the past. It is already known that skipping breakfast increases the prevalence of hypertension, diabetes, dyslipidemia, and cardiovascular disease. As people are becoming aware about obesity, weight management is also emerging as an important issue. This study was conducted to examine the influence of the frequency of breakfast intake on body mass index and body weight changes in Korean adults.
Methods: This study was conducted with results from the Korea National Health and Nutrition Examination Survey in 2014. Those aged 19 years and older (1,524 men and 2,008 women) were included in this study, excluding those who skipped lunch and dinner. The student’s t-test and chi-square test were used to analyze the relationship between breakfast habits and general characteristics. A general linear model was applied to determine the association between skipping breakfast and body mass index. Logistic regression analysis was performed to evaluate weight changes according to breakfast consumption.
Results: People who were younger, highly educated, worked long hours, and engaged in regular aerobic exercise were more likely to skip breakfast. In both men and women, breakfast habits were not significantly associated with body mass index. However, in both men and women, skipping breakfast was not associated with weight loss, but was associated with weight gain.
Conclusion: In men and women, skipping breakfast is associated with weight gain.
