The effectiveness of theory-based intervention to improve haemoglobin levels among women with anaemia in pregnancy

ABSTRACT

@#health problem throughout the world. The effects of theexisting intervention in ensuring compliance to thesubscribed regimen and the impact of nutrition education inenhancing dietary modification during pregnancy inMalaysia have been minimal. This study aims to develop,implement and evaluate the effects of the Health BeliefModel educational intervention on haemoglobin level amonganaemic pregnant women.Methods: This is a quasi-experimental research with pre-post test design with control group involving 81 participantsper group from two health clinics in Sepang. The primaryoutcome was a change in the haemoglobin levels followingeducational intervention. Secondary outcomes includeknowledge on anaemia, Health Belief Model (HBM)constructs, dietary iron intake and compliance towards ironsupplementation. The intervention group received a HBM-based education intervention programme. Results: The response rate in the intervention and controlgroup were 83.9% and 82.7% respectively. Generalisedestimating equations analysis showed that the interventionwas effective in improving the mean haemoglobin level(β=0.75, 95%CI=0.52, 0.99, p<0.001), the knowledge score(β=1.42, 95%CI=0.36, 2.49, p=0.009), perceived severityscore (β=2.2, 95%CI= 1.02, 3.39, p<0.001) and increasedproportion of high compliance level (AOR=4.59, 95%CI=1.58,13.35, p=0.005).Conclusion: HBM-based health education programme hasproven to be effective in improving the haemoglobin levels,knowledge scores, perceived severity scores andcompliance level of participants. The study resultsemphasized on the effectiveness of such an approach,therefore it is recommended that future educationalinterventions which aim at increasing preventive healthybehaviours in pregnant women may benefit from theapplication of this model in primary health care settings.
