“…The role of the local environment plays in determining birth outcomes is ambiguous. There is evidence that the local environment influences the health of different populations in different ways (Elliot et al, 1996;Ahern et al, 2003;Wen et al, 2003;Beckman et al, 2004;Diez-Roux et al, 2004;Sundquist et al, 2004).
