[[alternative]]Family diet and physical activity study for parents and adolescents

[[abstract]]The purpose of this study was to explore the associations on dietary intakes and physical activities between parents and their adolescent children aged from 12 to 15 years old. We recruited students and their family members from Taipei Municipal Cheng-Cheng junior High School in Nang Kan area and conducted face-to-face interviews at home to collect dietary, physical activity, and related family information by the structured questionnaires. Total 70 families consisting of 59 fathers, 67 mothers, 37 boys and 45 girls between aged 12-15 were included in the final analyses. The results from children between 12-15 years old show that the means of protein and vitamin B2 intakes by 24-hour recalls were significantly higher in boys than girls (p<0.05). The nutrient densities per 1000 kcal of vitamin C from food frequency questionnaire were higher in girls than boys (p<0.05). The frequency of eating-out for each meal was higher in boys than girls. There was significant positive correlation between the frequency of eating-out meals and extra lessons after school for girls (r=0.34，p<0.05). Girls had higher rates of participation in walking to school than boys and spent 5-15 minutes in walking mainly. Boys spent longer time than girls on physical activities per week, mostly in high intensity activities. There were significant positive correlations between mothers and daughters , fathers and daughters for protein (r=0.32、0.44，p<0.05), and between mothers and sons, fathers and sons for vitamin C (r=0.46、0.46，p<0.05) by 24-hour recalls. There were significant positive correlations between fathers and daughters on nutrient densities per 1000 kcal for protein、vitamin C、polyunsaturated fatty acid (r=0.50、0.39、0.33，p<0.05), and between fathers and sons on fat intake (r=0.38，p<0.05) by food frequency questionnaire. As for physical activity relationships between parents and adolescents, significant positive correlations were found between mothers and their daughters in exercise activity (r=0.56，p<0.05), and between walking of mothers and exercise activity of sons (r=0.42，p
