Background Although childhood respiratory tract infections and low birth weight have both been associated with reduced adult lung function, little is known about the timing of these associations during life. We used data from the Newcastle Thousand Families Study, to examine how these, and other, factors influenced forced expiratory volume in the first second (FEV1) at age 14 years and between ages 14 and 49-51 years. Methods Detailed information was collected prospectively during childhood. At aged 14 years, 252 members of the cohort were recruited into a case-control study of respiratory health, which included measurement of FEV1. 122 of these were measured again at aged 49-51. Linear regression models were used to examine cross-sectional and longitudinal influences on FEV1. Results Lower height (p1 at age 14 years. Correspondingly, being female (p1 at age 14 years (p1 between ages 14 and 49-51 years. Conclusion This study suggests that the change in FEV1 between youth and middle age depends on several factors acting throughout life including FEV1 in adolescence, sex, cigarette smoking history, birth weight, and childhood respiratory health.
