Multivariable associations of childhood socioeconomic position (SEP) with forced expiratory volume in 1 second (FEV1)
| Childhood measure of SEP | Difference (95% CI) in FEV1 (SD) | ||
|---|---|---|---|
| Model 1* | Model 2† | Model 3‡ | |
| SD = standard deviation (1 standard deviation FEV1 = 0.52 l). | |||
| *Adjusted for nurse, age, and height squared. | |||
| †Adjusted for nurse, age, height squared, smoking, body mass index, physical activity, adult social class, and respiratory treatment. | |||
| ‡Adjusted for nurse, age, height squared, smoking, body mass index, physical activity, adult social class, respiratory treatment, and each of the other childhood indicators of SEP (first column). | |||
| Manual – non-manual social class | −0.23 (−0.30 to −0.47) | −0.16 (−0.23 to −0.10) | −0.12 (−0.19 to −0.05) |
| House without bath – house with bath | −0.13 (−0.19 to −0.07) | −0.08 (−0.13 to −0.02) | −0.01 (−0.10 to 0.09) |
| House without hot water – house with hot water | −0.13 (−0.19 to −0.08) | −0.08 (−0.14 to −0.03) | −0.03 (−0.13 to 0.06) |
| No car access – car access | −0.19 (−0.27 to −0.12) | −0.14 (−0.21 to −0.07) | −0.10 (−0.16 to −0.02) |
| Shared bedroom – bedroom of own | −0.11 (−0.17 to −0.05) | −0.08 (−0.13 to −0.02) | −0.03 (−0.09 to 0.03) |
