[BDSP. Notice produite par INIST-CNRS f9o8R0xP. Diffusion soumise à autorisation]. Background : Socioeconomic status (SES) may contribute to the trajectory of pulmonary function over the life course. Studies suggest that people with lower (versus higher) SES during childhood subsequently have lower levels of adult pulmonary function. But prospective studies are sparse across young adulthood, an important phase in pulmonary development. Methods : Participants were from the Coronary Artery (Disease) Risk Development in (Young) Adults (CARDIA) study : 5113 young adults ages 18-30 at baseline, approximately balanced within centres across gender, self-identified race/ethnicity (Black, White), and current SES. Childhood SES was ascertained from baseline self-reports of parents'highest completed education. Pulmonary function in young adulthood was measured using FEV1 (forced expiratory volume in one second) and FVC (forced vital capacity), assessed on three occasions over a period of 5 years. Results : Longitudinal analyses suggested that rates of change in both FEVI and FVC differed in a gradient fashion by childhood SES. As shown by significant childhood SES by time interaction terms, these associations with FEV1 were robust for men (b=1.59E-3, SE=5.21E-4, P
