Abstract
Objective: To evaluate the effectiveness of a ‘health
promotional’ intervention by lay people in
changing determinants of low birth weight, when
added to the existing package of antenatal care
provision.
Method: A quasi-experimental study design was
used. An intervention was carried out among 403
pregnant women and their partners. Intervention
group (IG) was recruited from participants registered
to routine field antenatal services in the
Anuradhapura district. A comparison group (CG) of
403 pregnant women and their partners was
recruited from an adjacent district. Both groups were
recruited in the first trimester of pregnancy. The
intervention was based on health promotion
principles and used a model previously piloted in Sri
Lanka. Data from the Child Health Development
Record (CHDR) available at the health clinic were
used to determine birth weights.
Results: Significant improvements were seen in the
IG, compared to the CG, in the care given to the
pregnant mothers by their families, and level of
control over identified determinants of low birth
weight (LBW). The prevalence of LBW in the IG
was 10.0% and in the CG 19.2%. (X2=12.465;
p<0.001) with an adjusted OR of 0.5 (95% CI; 0.2-
0.8) and mean birth weight in the IG 2987g and in
the CG 2772.4g (t=6.934; df=726; p<0.001).

Conclusion: The community centred health
promotion intervention model was effective in
enabling lay communities to change selected
determinants of LBW and enabled lay communities
to change determinants of LBW.
