Results Descriptive Characteristics of Participants In total of 605 children participated in the study (age range 5-14 years, mean age 8.81
years, ±2.2, 44% female). Those children (n=58) not included in the study were absent
from school or class during questionnaire administration; no statistical differences in age
or gender with the main sample were noted (age range 6-13 years, mean age 9.05, ±
2.08, 44% female).
Behavioural determinants Free Play Physical Activity: Break and Lunch-Time: Participation in sedentary,
moderate or vigorous activity by gender for break-time and lunch-time is shown in
Table 4.4.

Although there is no significant difference for gender it can be seen that more boys
(72.8% at break-time and 79.5% at lunch-time) than girls (36.7% at break-time and
43.6% at lunch-time) reported participation in vigorous physical activity, whilst girls
were more likely to choose sedentary activities. Girls were significantly more likely to
report participating in vigorous activities at lunch-time (43.6% vigorous versus 16.6%
133
sedentary) (χ

(2) = 85.47, p< 0.001) as opposed to break-time (36.7% vigorous versus
29.2% sedentary) (χ

(2) = 78.84, p< 0.001). Boys were equally likely to be vigorously
active at break and lunch time.
