Crump C, et al. - In view of the linking of preterm birth with cardiometabolic, respiratory, and neuropsychiatric disorders in adulthood, researchers examined the prevalence of survival without major comorbidities in adulthood among persons born prematurely. They performed a national cohort study of all 2,566,699 persons born in Sweden from January 1, 1973, through December 31, 1997, who had gestational age data and followed them for survival and comorbidities through December 31, 2015 (ages 18-43 years). Survival at ages 18 to 43 years was reported in 54.6% of those born preterm (gestational age < 37 weeks) and 22.3% of those born extremely preterm (22-27 weeks) with no major comorbidities, when compared with 63.0% of those born full-term. Statistically significantly lower prevalences were observed in those born at earlier gestational ages vs full-term. These findings suggest that a large percentage of Swedish persons who born prematurely survived into adulthood and had no major comorbidities.
