Pregnancies in adolescent and older women have implications for maternal and child health. The topic is relevant at present, as first-birth rates for women aged >35 years have increased exponentially [2]. A number of studies showed an association between maternal age and respiratory symptoms and asthma in childhood, suggesting that lung development might differ between children born to very young or very old mothers [3]. However, the evidence for longer lasting effects is scarce.Adjusting for residual confounding when studying perinatal factors and offspring health can be difficult but it is very important for designing future studies http://ow.ly/H78y30kPxMZ ER -
