Correlation coefficients of food habits score and anthropometric measurements were that salty of food was negative and food habits scores were positive correlation for anthropometric measurements and obesity index (p < 0.05 - p < 0.001). Frequency of exercise and fitting exercise for body were different among three groups (p < 0.05). Obesity group was lower frequency of exercise than the other groups. Regular diet was positive correlation with food combination (p < 0.01), taking fish (p < 0.05), taking vegetables (p < 0.01), taking bean products (p < 0.01) and food habits score (p < 0.01), frequency of eating out and snacks were negative correlation with taking fruits and fishes.
