Stockholm county formed a separate group. <jats:italic>Main outcome measures.<\/jats:italic> Perinatal morbidity. <jats:italic>Results<\/jats:italic>. In counties with the most active management, 19% of pregnancies &gt;41<jats:sup>+2<\/jats:sup> GW were delivered at &gt;42<jats:sup>+2<\/jats:sup> GW during 2000\u20132004 compared to 7.1% in 2005\u20132007. In the least active counties, corresponding figures were 21.0% compared to 19.4%. During 2005\u20132007, the odds ratios for meconium aspiration and 5\u2010minute Apgar score of <jats:bold>\u2264<\/jats:bold>6 in the least compared to most active counties, were 1.55 (95% CI: 1.03\u20132.33) and 1.26 (95% CI: 1.06\u20131.51). In Stockholm &gt;42<jats:sup>+2<\/jats:sup>GW seen among pregnancies of &gt;41<jats:sup>+2<\/jats:sup> decreased from 21.0% in 2000\u20132004 to 5.9% in 2005\u20132007. Reduced perinatal death risks by 48%, meconium aspiration of 51% and low Apgar scores by 31% in 2005\u20132007 compared with 2000\u20132004 were observed.
