Background Adolescent pregnancy is a public health concern in Malawi as it is associated with high risks of adverse pregnancy outcomes. Almost 29% of adolescent women aged 15–19 years are already mothers and adolescent fertility rate is also high estimated at 136 per 1000 women. Therefore, the aim of the study was to explore knowledge of pregnant adolescents on importance of antenatal care and health promotion during pregnancy. Methods A qualitative descriptive design was used to solicit information on significance of antenatal care and how adolescents promote their health during pregnancy. Data was collected from 77 pregnant adolescents, purposively sampled from Namitambo and Namadzi Heath Centres in Chiladzulu District, Malawi. A semi-structured interview guide was used for data collection. Data were analysed manually following principles of qualitative content analysis. Results Themes that emerged from the qualitative data included: knowledge deficit on the purpose and benefits of antenatal care; knowledge deficit on services offered at antenatal care clinic; knowledge deficit on danger signs during antenatal period and antenatal emergency care; knowledge deficit on effects of alcohol and smoking; knowledge deficit on nutrition during pregnancy; and knowledge deficit on importance of rest during pregnancy. Conclusion This study has shown knowledge deficit among adolescent mothers that may contribute to poor pregnancy outcomes. Several factors could be attributed to such knowledge deficit. Therefore, healthcare systems and healthcare professionals have a responsibility to enhance health literacy of pregnant adolescents with an ultimate goal of improving maternal and neonatal health outcomes.

Background Information, education, and communication is a strategy to spread awareness through communication channels to a target audience to achieve a desired positive result. Women are supposed to receive information, education, and communication at each contact with the health worker during antenatal care. In Malawi, information, education, and communication for antenatal care is inadequate despite high antenatal care coverage. Most women do not receive it as stipulated. This could be one of the reasons that maternal and neonatal mortality is high. The provision of information, education, and communication is supposed to help in reducing maternal mortality because it is intended to develop positive attitudes towards health behaviours to support pregnant women accessing health services when required. This study, therefore, assessed the status of information, education, and communication as perceived by clients receiving antenatal care at Chiradzulu District Hospital in Malawi. Methods A descriptive study design with a sample of 384 pregnant women attending antenatal care was used. The sample size for the study was calculated using Lemeshow, Hosmer, Klar and Rwanga's formula. Systematic random sampling method was used to select the study participants. Data were analysed using a statistical package for social sciences software version 20.0. Results Findings revealed that information, education, and communication provided during antenatal care were inadequate. Most information was offered. However, no topic was rated adequate by 80% of the respondents according to the Likert Scale that was used. The majority of the respondents (71.4%, n = 274) (95% CI 66.5. 75.8) preferred to receive information, education, and communication from midwives who are in the category of skilled attendants. Results further showed that more than half of the respondents participated passively and spent little time receiving information, education, and communication. Conclusion The findings signify that information, education, and communication provided to women receiving antenatal care at Chiradzulu District Hospital had some gaps. It was inadequate and some topics were not taught. The target audience participated passively. It is recommended that midwives should provide the information, education, and communication and must have adequate contact time with the women. This is so because they are believed to be trusted sources of information.
