Effect of nutrition education by health professionals on pregnancy-specific nutrition knowledge and healthy dietary practice among pregnant women in Asmara, Eritrea: a quasi-experimental study.

Background: Healthy pregnancy and birth outcomes are greatly influenced by the intake of adequate and balanced nutrition. Pregnant women's nutritional knowledge and practice have been identified as an important prerequisites for their proper nutritional intake. The antenatal period with the opportunities for regular contact with health professionals appears to be the ideal time and setting to institute the intervention which could maximise pregnant women's outcome and that of their baby by motivating them to make nutritional changes.

Objective: To assess the effect of nutrition education on the appropriate nutritional knowledge and practice of pregnant women.

Methodology: A facility-based single-group pre-post quasi-experimental study design was employed in five health facilities providing antenatal care (ANC) service in Asmara on 226 pregnant women. A predesigned and pretested questionnaire was used to collect data regarding nutritional knowledge via interview by trained data collectors during the pretest, immediate post-test and 6 weeks later. The practice was assessed at pre-intervention and 6 weeks later only. Repeated measures analysis of variance and paired t-test were used to make comparisons in knowledge and practice scores, respectively, using SPSS (V.22).

Results: Training provided to pregnant women resulted in a significant increase on the mean scores of their knowledge from 29.01/47 (SE=0.35) pre-intervention to 42.73/47 (SE=0.24) immediate post-intervention. However, the score declined significantly from immediate after intervention to 6-week follow-up by 1.79 (SE=0.22). Although the score declined, knowledge at 6-week follow-up was still significantly greater than that of pre-intervention (p<0.0001). Health professionals (70.2%) were the primary source of information for pregnant women. The pregnancy-specific dietary practice score at 6-week follow-up (M=13.13/16, SE=0.09) was significantly higher than that of pre-intervention (M=12.55/16, SE=0.16). There was no significant interaction between the categories of demographic characteristics and change in practice and knowledge.

Conclusion: This study has shown that the nutrition messages given to pregnant women by trained health professionals using a holistic approach in a sustained manner played a huge role in increasing their knowledge and in introducing positive dietary practices among them. Thus, ANC clinics must play a leading role in coordinating the effort of awareness creation regarding nutrition during pregnancy.
