  • Abbreviation: FEV1 = forced expiratory volume in the first second.

  • NOTE: P values < 0.05 are denoted in bold.

  • * For light activity and strenuous physical activity, change scores represent regression estimates in minutes of activity per week, with positive scores denoting an increase in activity and negative scores a decrease in activity. For sedentariness, change scores are log odds ratios, with positive scores denoting a greater likelihood of becoming sedentary and negative scores denoting a lower likelihood of becoming sedentary.

  • Sedentary defined as engaging in no light, moderate, or strenuous intensity activity.

  • For comparison with normal weight individuals.
