Participants Students were recruited in September 2005 via invitation/information

letters sent home by the teachers. Written consent was obtained from parents/guardians; children gave verbal and written assent. In all, 1494 students consented to participate in the study at baseline. Stattic Of those, 1441 students were measured (n = 52 students were absent and n = 1 moved prior to being measured). The 1421 children who completed the question regarding their participation in organized sport that was part of the Physical Activity Questionnaire for Children (PAQ-C) were included in the analysis. Measurement procedures Descriptive characteristics Stretched stature to the nearest 0.1 cm (Seca 214 Portable Stadiometer) and weight to the nearest 0.1 kg (Conair digital electronic scale) were each measured twice and the mean was used in the analysis. Body Mass Index

Vactosertib (BMI) was calculated from height and weight as kg/m2. Overweight/obesity was calculated using age and BMI [12]. Dietary measures Two instruments were used to assess the diet of each participant. The EHSA Food Processor Nutrition and Fitness Software (v. 10.0, Salem, OR) was used to determine macronutrients (also including total calories, fibre and sugar) learn more consumed from a validated 24-hour dietary recall [13]. As well, fruit, vegetables, milk, 100% fruit juice, sports drinks and SSBs (including flavoured milk, carbonated beverages, non-carbonated flavoured beverages, sweetened coffee and tea, and sports beverages) were hand-tallied from the dietary

recall, with serving size determined using the Canadian Nutrient File [14]. Typical frequency of fruit, vegetable, milk and 100% fruit juice consumption was assessed using a targeted Food Frequency Questionnaire (FFQ) adapted from the US National Cancer Institute’s National Institutes of Health: Eating at America’s Table Study Quick Food Scan [15]. Physical activity Physical activity and participation in organized sport was measured using a modified version click here of the PAQ-C [16]. The PAQ-C is a valid and reliable tool for assessing moderate-to-vigorous physical activity (PA) over the previous 7 days [16, 17]. The physical activity score (PA score) ranges from 1 (low active) to 5 (high active) and was calculated from the mean score of nine questions related to frequency and intensity of PA. In addition, students were asked if they participated in organized sport outside of school and then to describe the sport activity and indicate the days they participate in that sport during the week. Those who reported participation in any organized sport and identified the sport and participation frequency were assigned to the ‘sport’ group and those who did not were assigned to the ‘non-sport’ group.
