Potential Association between Breakfast Skipping and Concomitant Late-Night-Dinner Eating with Metabolic Syndrome and Proteinuria in the Japanese Population

الملخص EN

Skipping breakfast is considered to be an unhealthy eating habit linked to predispositions to obesity and type 2 diabetes.

Because eating dinner late at night can elicit subsequent breakfast skipping, we investigated if skipping breakfast concomitant with late-night-dinner eating (LNDE) was associated with metabolic syndrome (MetS) and proteinuria in the general Japanese population.

We examined self-reported habitual breakfast skipping and LNDE, MetS (modified ATP-III criteria), and proteinuria in a cross-sectional study of 60,800 Japanese adults aged 20–75 years.

A total of 14,068 subjects (23.1%) skipped breakfast, of whom approximately half (52.8%) skipped breakfast alone (without LNDE).

The percentages of subjects who skipped breakfast showed a J-shaped relationship with body mass index (BMI).

Multivariate logistic regression analysis showed that skipping breakfast concomitant with LNDE (n = 6,645) was significantly associated with MetS and proteinuria, even after adjusting for relevant confounders (odds ratio (95% CI), 1.17 (1.08–1.28), P=0.0003, and 1.37 (1.24–1.52), P<0.0001, resp.).

Skipping breakfast alone and LNDE alone were not associated with MetS and proteinuria, respectively.

In conclusion, habitual breakfast skipping concomitant with LNDE may represent poorer eating behavior than skipping breakfast alone, associated with MetS, asymptomatic proteinuria, obesity, and low body weight in the general Japanese population.
