ABSTRACT
Objective@#Dietary factors are important contributors to obesity and related metabolic disorders. Few studies have evaluated the impact of dietary habits (e.g., breakfast consumption frequency and meal regularity) on metabolic health. We investigated the effects of breakfast consumption frequency and meal time regularity on nutrient intake and cardiometabolic status in Korean adults. @*Methods@#Participants without diagnosed diseases (n=217) were examined for anthropometric and biochemical parameters, lifestyle, dietary habits, and nutrient intake.They were categorized into 4 groups by breakfast consumption frequency (≥6 or <6 times/ week) and meal time regularity (regular or irregular): breakfast ≥6 times/week and regular eating (HBRE), breakfast ≥6 times/week and irregular eating (HBIE), breakfast <6 times/week and regular eating (LBRE) and breakfast <6 times/week and irregular eating (LBIE). @*Results@#Participants in the LBIE group were the youngest, had higher waist circumference, body mass index, triglyceride levels, and inflammation, and consumed the highest daily total caloric intake (TCI), the highest proportion of fats, and the lowest proportion of carbohydrates. The LBIE group also had the lowest proportion of energy intake at breakfast and the highest proportion at dinner. The LBIE group consumed the lowest amounts of fiber, beta-carotene, vitamin K, folate, calcium and iron, and had the highest prevalence of inadequate nutrient intake for TCI, protein, vitamins A, C, B6, and B12, folate, calcium, iron, zinc, and copper. @*Conclusion@#Regular breakfast consumption and meal times are related to healthy lifestyle habits and adequate nutrient intake, which affect metabolic health, thereby helping prevent obesity and related metabolic disorders.

ABSTRACT
This study aimed to investigate the relationship between meal regularity (i.e. breakfast intake and meal-times), and the risk of metabolic syndrome (MetS) among generally healthy Korean single-person household adults (≤60 years, n=594) based on the Seventh Korean National Health Examination and Nutrition Survey (KNHANES) (2016∼2018).Among men (n=325), the breakfast intake frequency was not significantly associated with the pervalence of MetS. However, men consuming a regular meal at least once a day showed a lower prevalence of MetS compared to those whose meals were irregular. These patterns remained after adjusting for age, smoking and drinking habits, individual income, education level, exercise, and total calorie intake. An association between meal regularity and MetS risk was observed in post-menopausal women (n=84), but not in pre-menopausal women (n=185). More specifically post-menopausal women with irregular breakfast eating habits or eating no breakfast at all showed a significantly higher risk of MetS than those eating breakfast regularly after the adjustment. The analysis revealed an odds ratio (OR) of 8.46, confidence intervals (CIs): 1.149∼62.199, P＜0.05 in irregular breakfast eaters, and an OR of 13.377, CIs: 1.665∼ 107.511, P＜0.05, in those who ate no breakfast. Furthermore, post-menopausal women who had irregular meals daily showed a higher risk of MetS than those consuming one or more regular meals/day after the adjustment (OR:16.888, CIs: 1.258∼226.655, P＜0.05). In conclusion, the results from this study may be used for formulating optimal dietary guidelines for the prevention and the management of MetS in adults in single-person households.
