BACKGROUND: Obesity affects lung function and respiratory muscle strength. The aim of the present study was to assess lung function and respiratory muscle strength in @entity1 with @entity28 and determine the influence of body composition on these variables. METHODS: A cross-sectional study was conducted involving 75 @entity1 (40 with @entity28 and 35 within the ideal weight range) aged 6 - 10 years. Body mass index, z score, waist circumference, body composition (tetrapolar bioimpedance), respiratory muscle strength and lung function (spirometry) were evaluated. RESULTS: @entity1 with @entity28 exhibited larger quantities of both lean and fat mass in comparison to those in the ideal weight range. No significant differences were found between groups regarding the respective reference values for respiratory muscle strength. Male @entity1 with @entity28 demonstrated significantly lower lung function values (forced expiratory volume in the first second % (FEV1%) and FEV1/forced vital capacity % (FVC%) : 93.76    9.78 and 92.29    3.8, respectively) in comparison to males in the ideal weight range (99.87    9.72 and 96.31    4.82, respectively). The regression models demonstrated that the spirometric variables were influenced by all body composition variables. CONCLUSION: @entity1 with @entity28 demonstrated a reduction in lung volume and capacity. Thus, anthropometric and body composition characteristics may be predictive factors for altered lung function.
