Army families in the UK have been observed to have a higher infant mor
tality compared with the civilian population. Little is known about th
e reasons for the higher mortality. We report a comparative study of t
he health of army and civilian babies and their families in a UK garri
son town, the aim being to investigate any differences in risk factors
which may have explained the differences in mortality. A total of 250
first born army and civilian babies fulfilling the selection criteria
were recruited to the study. Army babies had a lower birth weight dis
tribution and both maternal and paternal smoking rates were higher in
army families. In addition, social support and in particular, contact
with close family members appeared to be available to fewer army mothe
rs. The study highlighted the needs of this population and prompted a
number of local health services to work together to address the issues
it raised.
