Abstract

HIV and AIDS incidence among infants in South Africa is on the increase.The uptake of prevention of motherto- child transmission (PMTCT) interventions is often said to be dependent on the beliefs and educational needs of those requiring PMTCT services.This study therefore sought to examine the effect of clinic-based health education interventions (HEI) on behavioural intention of PMTCT among 300 pregnant women from 4 primary health care clinics in Tshilidzini Hospital catchments area, South Africa. An interview schedule was used to obtain information regarding participants' demographic characteristics, level of exposure to clinic-based HEI, salient beliefs and behavioural intention on PMTCT.The major findings included that approximately 85% of the participants had heard of PMTCT.There was very little association between frequency of antenatal clinic (ANC) visits and level of exposure to PMTCT information. Condom use had the lowest set of salient belief scores. Control belief was the most common belief contributing to behavioural intention. Generally, the association between PMTCT salient beliefs and behavioural intention was weak. Clinic-based HEI had an impact on behavioural intention of HIV testing, normative belief of regular ANC visit and nevirapine use.The vital contribution of alternative PMTCT information sources such as the radio and television was observed. Enhancing initiatives that empower women, and a better coordination of the existing HEI through better implementation of health education strategy may strengthen the prevailing moderate PMTCT intention in the area investigated.

Résumé

Le cas de VIH/SIDA augmente parmi les bébés en Afrique du Sud. L'assimilation des interpositions de prévention de transmission mère á enfant (PMTCT) est souvent vu d'être dépendante de croyances et de besoins éducatifs de ceux qui ont besoin des services PMTCT. Cette étude a pour but de vérifier l'effet des interpositions de l'éducation sanitaire clinique-basées (HEI) sur l'intention comportementale de PMTCT auprès de 300 femmes enceintes originaires de 4 services de santé primaire dans les bassins de captation de l'hôpital Tshilidzini, en Afrique du Sud. Un barème d'entretien a été utilisé pour obtenir des informations concernant les caractéristiques démographiques des participants, le niveau d'être exposé aux HEI clinique-basées, les croyances principales et l'intention comportementale sur les PMTCT. Les résultats principaux ont démontré qu'approximativement 85% de participants avaient déjà entendu parlé de PMTCT. Il y a eu une association très étroite entre la fréquence de visites antenatales et le niveau d'être exposé à l'information de PMTCT. L'utilisation du préservatif avait les résultats de croyances principales les plus bas. La croyance de commande était la croyance la plus commune qui contribue à l'intention comportementale. En général, l'association entre les croyances principales des PMTCT et l'intention comportementale était faible. Les HEI clinique-basées avaient un impact sur l'intention comportementale du dépistage de VIH, la croyance normative des visites antenatales régulières et la prise du nevirapine. La contribution primordiale des sources alternatives d'informations sur les PMTCT comme la radio et la télévision a été observée. Rehausser les initiatives vers le développement des femmes et la coordination meilleure de HEI qui existent à travers une meilleure mise en oeuvre de la stratégie de l'éducation sanitaire pourraient renforcer l'actuelle intention modérée des PMTCT dans le lieu en question.
