Introduction The relationship between obesity or
overweight and pulmonary functions has not been
investigated in Sri Lankan children previously. Therefore,
we aimed to study the effects of obesity / overweight on
dynamic lung functions in healthy school children in Sri
Lanka.
Methods This cross sectional study was carried out
among healthy school children. They were categorised
into ‘obese/over weight’ group (BMI > 85th percentile) and
'normal weight’ group (BMI 5"1-85lh percentile). Forced vital
capacity (FVC), forced expiratory volume in one second
(FEV1) and forced expiratory flow at 25-75% (FEF 25-75%)
were used as measures of ventilatory function.
overweight’. BMI has no significant relationship to any of
the pulmonary function parameters. However, in contrast
to what is expected, mean values o f FVC, FEV, and FEF
25-75% were lower in ‘normal weight’ group (Table 2).
Conclusions No significant difference was detected in
spirometry parameters between obese/overweight and
normal weight school children in our study.
