Background: A third of pregnant women in Nigeria do not attend Antenatal care, hence this quasi-experimental study was carried out within 500 consenting pregnant women within the 5 administrative zones of Lagos to determine the association between Mhealth services and utilization of antenatal and skilled delivery services amongst pregnant women in Lagos, Southwest Nigeria.Methods: Participants were divided into an intervention (who received voice messages) and a control arm (did not receive voice messages). Ownership of a mobile phone and willingness to participate were the selection criteria. Data was collected using a structured interviewer administered questionnaire. Analysis was by descriptive statistics with 95% CI to identify factors associated with antenatal attendance.Results: Total respondents were 488 (response rate 97.6%). One hundred and fifty-nine (63.8%) of the intervention group found the messages useful. Using the WHO 2016 ANC model, women in the intervention group had a significantly higher frequency of antenatal care attendance than the control group (p < 0.0001). There was a statistically significant difference in antenatal attendance between the intervention and the controls (p < 0.0001). There was also a significantly lower likelihood of poorly supervised (unskilled) home deliveries within the intervention arm (p=0.011). Conclusion: Mhealth was associated with an increased antenatal attendance and skilled birth attendance at delivery. This has a significant impact in reducing morbidity and mortality indices.

Background. Nigeria has one of the lowest antenatal care (ANC) utilization rates compared to other low- and middle-income nations. In order to ensure a positive pregnant experience, the World Health Organization recommends at least eight ANC visits during pregnancy. This study intends to examine the impact of a mobile phone-based voice message intervention on ANC use in Lagos, Nigeria. Methods. In this cluster-randomized experiment, primary healthcare centres were divided into five intervention and five control groups using multistage simple random sampling. The intervention consisted of a weekly voice message transmitted through mobile phone from the time of recruitment in the first trimester until two weeks postpartum. Attending at least eight ANC visits before birth was the primary outcome. STATA v17.0 was used to conduct descriptive and bivariate analyses as well as multivariate linear models to calculate crude risk ratios. Results. 458 women participated. All intervention group women (269 women, or 58.7% of the sample) received the text message. These ladies were mostly married, Christian, had several children, and had completed high school. Women who received the intervention were more likely to attend eight ANC visits. Conclusion. A voice message-based intervention can boost ANC utilization, according to the conclusion. This contributes to the existing body of information about the influence of mHealth treatments on maternal health outcomes and serves as a useful tool for ensuring that no woman is left behind.
