Adjusting for length, age, and sex, we found a mean significant reduction of 92 ml\/s (22%) in FEF50, 73 ml\/s (21%) in FEF25\u201375, and 19 ml (28%) in FEV0.5 in the preterm group. These differences in expiratory flows remained significant using another model that adjusts for lung volume (p &amp;lt; 0.01 for FEF50, FEF25\u201375, and FEV0.5, and p &amp;lt; 0.05 for FEF75). In the preterm group, after adjusting for length, male sex, lower gestational age, and increased weight were significantly and independently associated with reduced flows.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings confirm that prematurity is independently associated with reduced lung function and that this is detectable in the first months of life.
