Abstract
Background: Childhood obesity has become a global epidemic. It
is related to several chronic diseases such as essential hypertension,
type 2 diabetes mellitus, and renal disease. The relationship between
the degree of obesity and lung functions is well defined in adults, but
limited information is available about the childhood period.
Aims: This study aims to determine the impact of the degree of
obesity on the pulmonary functions of school children and adolescents.
Study Design: Cross sectional study.
Methods: Included in the study were a total of 170 school children
and adolescents (9-17 years old) referred to our paediatric outpatient
clinic. Of these subjects, 42 were lean and non-obese (BMI % <85),
30 subjects were overweight (BMI % ˃85, <95), 34 subjects were
obese (BMI % ˃95, <97), and 64 subjects were morbidly obese (BMI
% ˃97). Anthropometric measurements were taken and spirometry
was performed on all subjects. Forced vital capacity (FVC), forced
expiratory volume in 1 second (FEV1
), forced vital capacity 25-75
(FEV25-75) and peak expiratory flow (PEF) were used to measure the
ventilatory functions for all the subjects.
Results: The groups showed no significant differences in age or gender. Despite no statistically significant differences in FEV1
, FVC, or
FEV1
/FVC, there were significant reductions in PEF (p<0.001) and
FEV25-75 (p<0.001) in the overweight, obese and morbidly obese subjects, when compared with those who were non-obese.
Conclusion: Overweight, obese and morbidly obese children have
no obstructive abnormalities compared with healthy lean subjects.
