Abstract
Objective To investigate the association between television viewing time and dietary patterns among preschool children. Methods All the children and their parents from 11 kindergartens in Hongkou District,Shanghai China were included. The Socio-demographic questionnaire was used to collect the basic information and television viewing time of the children. Dietary information was collected by using a simplified food frequency questionnaire( FFQ),which included children's common food intake during the past week. Principal component analysis was used to derive two dietary patterns based on the FFQ. Children's weight and height were also measured uniformly and BMI was calculated. Children's television viewing time was divided into 2 groups using 2 hours as the cutoff point and to explore the association between television viewing time and dietary patterns. Results The final sample consisted of 1 670 children,boys accounted for 49. 3%. And average BMI was(15. 8 ± 1. 8)kg·m_2 and BMI Z score was 0. 015 ± 0. 96. ①On weekdays children who watched TV more than 2 h·d_1 were 12. 9%,while at weekends were 36. 6%. ②Two dietary patterns were labeled as 〝the traditional dietary pattern〝 and 〝the western dietary pattern〝. The former included fruits,vegetables,red meat,white meat and staple food,whereas the latter included snack,juice,soft drinks and white meat. ③Comparing with children watching TV less than 2 h·d_1 ,children spending more than 2 h·d_1 watching TV seemed to have lower traditional dietary pattern scores but higher western dietary pattern scores,even after adjustment for age,gender,BMI levels,and family income. ④Preschool children with higher western dietary pattern scores appeared to have higher BMI(β =0. 066,P=0. 006). Conclusion Western dietary patterns might be the risk factors for preschooler' obesity. Shorter television viewing time may be beneficial for pre-school children's dietary patterns. Children who have excessive television viewing time may need to be encouraged to consume a more healthy diet.关键词
