The percentage of grade 7s that reached the recommended level dropped to 45.3% for boys and 23.8% for girls, and in grade 11 only 9.7% of the boys and <1% of the girls were active enough to achieve the moderate physical activity recommendation. [...] In grade 7 approximately 40% of the boys and 35% of the girls achieved 60 minutes or more of physical activity on 3 to 4 days of the week suggesting that a small increase in physical activity on 1 or 2 days of the week may significantly increase the percentage of youth that would meet the Nova Scotia physical activity guidelines.

[...] In grade 7, 27.6% of the boys and 38.8% of the girls had a waist girth that was “at risk” or “unhealthy”, and in grade 11, 24.6% of the boys and 34.4% of the girls were “at risk” or “unhealthy” considering their waist circumference. [...] Similarly, 17.4% of the boys and 13.2% of the girls in grade 7 and 13.1% of the boys and 9.5% of the girls in grade 11 would be considered at the greatest health risk because of a combined “unhealthy” waist girth (i.e., > 95th age- and sex-matched percentile) and overweight BMI (i.e., > 95th age- and sex-matched percentile).
