Chest expansion measurement, normal value, healthy Thai children



This study aimed to investigate the normal value of chest expansion in healthy Thai children aged between 6 to 12 years old. Chest expansion was measured at upper and lower chest part. The results of 329 children (154 boys, 175 girls) showed the average of upper chest expansion in 6 to 12 year old boys were 3.08 ± 0.82, 2.92 ± 076, 3.03 ± 0.89, 3.57 ± 0.57, 3.06 ± 0.60, 3.69 ± 0.88 and 3.48 ± 0.76 cm, respectively, and the mean of lower chest expansion were 4.30 ± 1.14, 4.12 ± 0.76, 4.22 ± 0.93, 4.95 ± 0.78, 4.48 ± 0.86, 5.00 ± 0.74 and 4.74 ± 0.79 cm, respectively. For girls, the average of upper chest expansion were 2.40 ± 0.94, 3.52 ± 0.49, 3.25 ± 0.83, 3.19 ± 0.61, 3.46 ± 0.77, 3.97 ± 0.81 and 3.61 ± 0.65  cm, respectively, and the mean of lower chest expansion were 3.57 ± 0.99, 4.95 ± 0.56, 4.34 ± 0.95, 4.62 ± 0.83, 4.71 ± 0.98, 5.36 ± 1.01 and 5.01 ± 0.79 cm, respectively. In this study, the mean of chest expansion between boys and girls in upper chest parts were statistically significant difference (p < 0.05) in 7, 9 and 10 years-old group. There was statistically significant difference  (p < 0.05) of lower chest parts in 7 year-old group.
