BACKGROUND: Early life development may influence subsequent respiratory morbidity. We addressed the impact of factors determined in childhood on adult lung function, lung function decline and chronic obstructive pulmonary disease (COPD). METHODS: European Community Respiratory Health Survey participants aged 20-45 years, randomly selected from general populations in 29 centres, had a spirometry in 1991-93 (n=13,359) and nine years later (n=7,738). Associations of early life factors with adult FEV1, FEV1 decline and COPD (FEV1/FVC ratio<70% ci="67-124];">/=3 factors men: 274ml[154-395], women: 208ml[124-292]. Childhood disadvantage was associated with larger FEV1 decline (one factor 2.0ml [0.4-3.6] per year; two factors 3.8ml [1.0-6.6]; >/=3 factors 2.2ml[-4.8-9.2]). COPD increased with increasing childhood disadvantage (one factor men: OR=1.7[95%CI=1.1-2.6], women: 1.6[1.01-2.6]; >/=3 factors: men: 6.3[2.4-17], women: 7.2[2.8-19]). These findings were consistent between centres, and when excluding subjects with asthma. CONCLUSIONS: People with early life disadvantage had permanently lower lung function, no catch-up with age but slightly larger lung function decline, and substantially increased COPD risk. The impact of childhood disadvantage was as large as that of heavy smoking. Increased focus on early life environment may contribute to prevent COPD.
