Objective This study was aimed at comparing cardiorespiratory fitness (CF), measured asVO2max, amongst school children exposed to varying levels of particulate matter (PM10), and air pollution in Bogotá, Colombia.
Methods This was a cross-sectional study; it involved 1,045 children aged 7-12 attending four public schools served by different public transit routes and systems. Three schools were classified as being highly polluted (HP) and one slightly polluted (SP). The children and their parents were surveyed to collect data regarding their socio-demographic characteristics, physical activity habits and respiratory disease background. Objective measurements of weight and height were used to calculate the body mass index. VO2max was estimated using the 20-meter shuttle-run test, previously validated for Bogotá. Spirometry was performed on 435 children.
Results After adjustment for covariates, no difference was found inVO2max between children attending SP or HP schools (girls SP 45.8 ml/kg/min cf HP 44.6 ml/kg/min, p=0.11;boys SP 47.2 ml/kg/min cf HP 48.2 ml/kg/min, p=0.41).
Conclusions VO2max levels did not differ amongst children attending schools exposed to high compared to low levels of air pollution and PM. A longitudinal study assessing children’s VO2max levels in relation to exposure to highly-polluted areas is warranted.
Abstract
Background: Promoting physical activity among children is important for disease prevention. However in Latin America there is uncertainty on the health implications of recommending physical activity to children in highly polluted environments.
Objective: The objective of this study is to compare the cardiorespiratory fitness measured asVO2max among children attending schools exposed to varying levels of particulate matter (PM10), and air pollution in Bogotá, Colombia.
Methods: The study population consisted of 1045 children aged 7-12 attending four public schools served by different mass transit systems. Schools were classified as low (LP) or highly polluted (HP). VO2max was estimated via the 20-meter shuttle-run test. Analyses were adjusted by socio-demographic characteristics, body mass index, physical activity habits, respiratory diseases history, and lung function tests.
Results: After adjustment for covariates, no difference in the VO2max was found between the children attending LP or HP schools (girls LP: 45.8 ml/kg/min vs. HP 44.6 ml/kg/min; p =0.11, boys LP 47.2 ml/kg/min vs. HP 48. 2 ml/kg/min; p =0.41).
Conclusions: VO2max levels did not differ among children attending schools exposed to high vs. low levels or air pollution and PM. A Longitudinal assessment of children’s VO2max levels in relation to exposure to highly polluted areas is warranted.
