| Summary: | Obese children have been highlighted as a particularly sedentary population and the
possible negative effects of a sedentary lifestyle are being uncovered. Total time spent
sedentary and the sedentary patterns of obese children have not been described using
objective and direct measure of body inclination. Therefore, the aims of this study are to
examine the patterns of objectively measured sitting/lying, standing and stepping in obese
children using the ActivPALTM and to highlight possible differences in sedentary levels and
patterns during weekday and weekends. One hundred and one obese children, age 9-11
years, were recruited from urban and rural schools in Kuala Terengganu. Participants wore
an ActivPALTM monitor for 7 days to measure total time of daily sitting/lying, standing and
stepping. The ActivPALTM output was examined using a customized macro Excel 2013. The
results shows that obese children tend to spend most of their days in sitting/lying (77.8%)
rather than standing (14.3%) and stepping (7.9%). There is significance different found in
sitting/lying during weekends compared to weekdays (19.3 hours vs 18.4 hours; p value
<0.001). Significantly more sedentary bouts were accumulated during weekdays compared
to weekends (p value <0.05). Sedentary behaviour was one of the factors that contribute
to childhood obesity. This is the first study in Malaysia that use activPALTM monitor to
measure sedentary behaviours in obese children. Interventions that target the sedentary
behaviour of obese children by displacing sitting with activity may offer most promise for
reducing population levels of sedentary behaviour and physical activity levels in school
children. |
