Gestational Age and Cardiorespiratory Fitness in Individuals Born At Term: A Life Course Study

Ferreira et al, J Am Heart Assoc. 2017 Sep



In contrast to the effects of preterm birth, the extent to which shorter gestational age affects the cardiorespiratory fitness (CRF) levels of individuals who were born at term (ie, between 37 and 42 weeks) is largely unknown. The aim of this study was to examine whether life-course CRF levels varied across different gestational ages within the at-term range.

Conclusions: These findings suggest that early-term births within the at-term range are linked to poorer CRF through adolescence to young adulthood, and may have important clinical and public health implications for policies about (avoidable) early-term deliveries given their recent increasing trends.
