PURPOSE: To investigate the relationship between skipping breakfast and cardiovascular disease risk factors such as blood pressure, serum lipids, smoking, and lock of exercise. MATERIALS AND METHODS: Data from the National Nutrition survey conducted by the Ministry of Health and Welfare, from 1995 through 1997 were employed for the analysis. Data were used only if subjects were between 20 and 59 years old and had participated in the nutrition survey, and values for height and weight, blood pressure, serum lipids, blood sugar, number of steps per day, and smoking, drinking, and exercise habits were available. The number of subjects with data available for all of the above was 11,778 (4,438 men and 7,340 women). Analyses were performed separately by sex. The relationship between skipping breakfast and continuous variables such as nutrient intake ratio (nutrient intake divided by recommended dietary allowances), body mass index, blood pressure, serum lipids, blood sugar, and the number of steps per day was examined controlling for age using analysis of covariance (ANCOVA). The relationship between skipping breakfast and categorical variables such as smoking, drinking, and exercise habits was assessed controlling for age using Cochran-Mantel-Haenszel statistics. RESULTS: The younger the generation, the higher the rate of skipping breakfast. The rate of skipping breakfast in men was twice as high as in women. The breakfast skippers tended to intake less energy and calcium, both in men and women, that non-skippers. Female skippers tended to intake less iron and vitamin D. The number of steps per day was smaller in breakfast skippers than that in non-skippers both in men and women. Male skippers tended to have higher blood pressure than non-skippers, and female skippers tended to have a higher serum total cholesterol level than non-skippers. The breakfast skippers tended to smoke more than non-skippers, both in men and women, and female skippers tended to drink more alcohol and take less exercise. CONCLUSIONS: Skipping breakfast is related to cardiovascular risk factors such as lack of exercise, smoking, high blood pressure, and high serum total cholesterol.
