Senior high school students had lowest everyday breakfast consumption rate, and highest daily sugar sweetened beverage consumption and screen time compared to elementary and junior high school students. Students of higher parental education level and higher family income had better eating behaviors and lower daily screen time. Parental education level, family income, daily screen time and parental weight status were independent risk factors of overweight and obesity among primary and middle school students. After adjusted by age, gender, socioeconomic status factors, breakfast frequency, sugar sweetened beverage consumption frequency, calorie intake and physical activities, only parental weight status was kept as a risk factor of overweight and obesity. Changes of the prevalence of overweight or obesity among grades were parallel to the changes of no daily breakfast consumption, calorie contributions from sugar sweetened beverage intake, and daily screen time. In conclusion, the prevalence of overweight or obesity among primary and middle school students were high in Taiwan. Parental weight status was important risk factors for obesity.
