Duration of diabetes (years)	10 ± 5	—	9 ± 5	9 ± 5	—	8* ± 4	13* ± 4	—
BMI (kg/m2)	22.6 ± 4	23.3 ± 4	21.8 ± 4	23.7† ± 6	24.0† ± 4	22.2 ± 3	22.5† ± 4	22.6† ± 4

Data are means ± SD unless otherwise indicated. Data are not shown for 167 children and adolescents in whom there were no significant differences in pulmonary function or BMI between those with and those without diabetes. (See text for details.)

*Significant difference (P < 0.05) in duration of diabetes between female subjects with and without fasting hyperglycemia.

†Significant differences (P < 0.05) between male and female subjects within a diagnostic subgroup (with fasting hyperglycemia, without fasting hyperglycemia, or with no CFRD).

‡Significant differences (P < 0.05) between CFRD and no CFRD.
