listen audio

Study Justification:
– Nigeria has poor maternal and child health indicators.
– Compliance with WHO guidelines on the minimum number of antenatal care (ANC) contacts could improve these indicators.
– This study aims to assess the compliance with WHO recommended standards on ANC contacts in Nigeria and identify associated factors.
Highlights:
– About 25% of women had no ANC contact, 58% had at least 4 contacts, and only 20% had 8 or more ANC contacts.
– The highest rates of 8 or more ANC contacts were in Osun (80.2%), Lagos (76.8%), and Imo (72.0%), while the lowest rates were in Kebbi (0.2%), Zamfara (1.1%), and Yobe (1.3%).

The strength of evidence for this abstract is 8 out of 10.
The evidence in the abstract is strong, as it is based on a nationally representative cross-sectional data of 21,785 most recent births. The study uses descriptive statistics and multivariable logistic regression to analyze the compliance with WHO guidelines on ANC contacts in Nigeria. The findings highlight the percentage of women with different levels of ANC contacts, the variation across states, and the factors associated with compliance. The study concludes that compliance is poor and recommends policy review, prioritizing women’s education and socioeconomic status, and addressing regional disparities. To improve the evidence, the study could have included a more detailed methodology section, provided more information on the data collection process, and discussed potential limitations of the study.

Background: Nigeria has unimpressive maternal and child health indicators. Compliance with the WHO guidelines on the minimum number of antenatal care (ANC) contacts could improve these indicators. We assessed the compliance with WHO recommended standards on ANC contacts in Nigeria and identify the associated factors. Methods: Nationally representative cross-sectional data during pregnancy of 21,785 most recent births within five years preceding the 2018 Nigeria Demographic Health Survey was used. The number of ANC contacts was categorised into “None”, “1–3”, “4–7” and “8 or more” contacts based on subsequent WHO guidelines. Descriptive statistics, bivariable and multivariable multinomial logistic regression was used at p = 0.05. Results: About 25 % of the women had no ANC contact, 58 % had at least 4 contacts while only 20 % had 8 or more ANC contacts. The highest rate of 8 or more ANC contacts was in Osun (80.2 %), Lagos (76.8 %), and Imo (72.0 %) while the lowest rates were in Kebbi (0.2 %), Zamfara (1.1 %) and Yobe (1.3 %). Respondents with higher education were twelve times (adjusted relative risk (aRR): 12.46, 95 % CI: 7.33–21.2), having secondary education was thrice (aRR: 2.91, 95 % CI: 2.35–3.60), and having primary education was twice (aRR: 2.17, 95 % CI: 1.77–2.66) more likely to make at least 8 contacts than those with no education. Respondents from households in the richest and middle wealth categories were 129 and 67 % more likely to make 8 or more ANC contacts compared to those from households in the lowest wealth category respectively. The likelihood of making 8 ANC contacts was 89 and 47 % higher among respondents from communities in the least and middle disadvantaged groups, respectively, compared to the most disadvantaged group. Other significant variables were spouse education, health care decision making, media access, ethnicity, religion, and other community factors. Conclusions: Compliance with WHO guidelines on the minimum number of ANC contacts in Nigeria is poor. Thus, Nigeria has a long walk to attaining sustainable development goal’s targets on child and maternal health. We recommend that the maternal and child health programmers should review existing policies and develop new policies to adopt, implement and tackle the challenges of adherence to the WHO recommended minimum of 8 ANC contacts. Women’s education, socioeconomic status and adequate mobilization of families should be prioritized. There is a need for urgent intervention to narrow the identified inequalities and substantial disparities in the characteristics of pregnant women across the regions and states.

Nigeria has 36 states and the Federal Capital Territory (FCT). The states are further grouped into 6 regions as shown in Fig. 1. Although the regions have no administrative functions, people within each region are deemed to have similar characteristics, culture, ethnicity, vegetation etc. The States are further subdivided into local government areas (LGAs). The LGAs are subdivided into wards which are political/health units. The wards are also known as enumeration areas (EAs). Following the new 2016 WHO ANC guideline, the Federal Ministry of Health in Nigeria developed an orientation package for a new ANC model in Nigeria in 2017. The model marked the transition from a minimum of 4 visits to a minimum of 8 contacts [19]. With an emphasis on contacts rather than visits, ANC providers were trained, orientated and directed to operationalize it [19].

N/A

The recommendation to improve access to maternal health in Nigeria, based on the study mentioned, is to review existing policies and develop new policies that prioritize adherence to the World Health Organization (WHO) recommended minimum of 8 antenatal care (ANC) contacts. This recommendation is important because compliance with the WHO guidelines on ANC contacts in Nigeria is currently poor, and improving compliance could significantly improve maternal and child health indicators.

Specifically, the study suggests that maternal and child health programmers should focus on the following areas:

1. Review and develop policies: The existing policies related to ANC should be reviewed to identify gaps and challenges in adherence to the WHO guidelines. New policies should be developed to address these challenges and ensure that pregnant women receive the recommended minimum of 8 ANC contacts.

2. Prioritize women’s education and socioeconomic status: The study found that women with higher education and higher socioeconomic status were more likely to make 8 or more ANC contacts. Therefore, efforts should be made to prioritize women’s education and improve their socioeconomic status to increase access to ANC.

3. Mobilize families: Adequate mobilization of families is crucial to ensure that pregnant women receive the recommended ANC contacts. Health education and awareness campaigns should be conducted to inform families about the importance of ANC and encourage their support in ensuring that pregnant women attend the required number of contacts.

4. Address inequalities and disparities: The study identified significant inequalities and disparities in the characteristics of pregnant women across regions and states in Nigeria. Urgent interventions are needed to narrow these gaps and ensure that all pregnant women, regardless of their background, have equal access to ANC services.

By implementing these recommendations, Nigeria can work towards achieving the Sustainable Development Goals targets on child and maternal health and improve access to maternal health services for all women in the country.

AI Innovations Methodology
To simulate the impact of the main recommendations on improving access to maternal health in Nigeria, the following methodology can be used:

1. Data Collection: Collect data on the number of ANC contacts and associated factors from a nationally representative sample of pregnant women in Nigeria. This can be done through surveys or by accessing existing data sources such as the Nigeria Demographic Health Survey.

2. Categorize ANC Contacts: Categorize the number of ANC contacts into “None”, “1-3”, “4-7”, and “8 or more” based on the WHO guidelines.

3. Descriptive Analysis: Calculate the percentage of women in each category of ANC contacts and examine the regional and state-level variations.

4. Multivariable Analysis: Conduct a multivariable logistic regression analysis to identify the factors associated with making 8 or more ANC contacts. Include variables such as education, socioeconomic status, spouse education, health care decision making, media access, ethnicity, religion, and community factors.

5. Policy Review and Development: Review existing policies related to ANC in Nigeria and identify gaps and challenges in adherence to the WHO guidelines. Develop new policies that prioritize adherence to the recommended minimum of 8 ANC contacts.

6. Impact Simulation: Simulate the impact of the policy changes by estimating the percentage increase in the number of women making 8 or more ANC contacts based on the identified factors. This can be done by applying the adjusted relative risks from the multivariable analysis to the population of pregnant women in Nigeria.

7. Sensitivity Analysis: Conduct sensitivity analysis to assess the robustness of the results by varying the assumptions and parameters used in the simulation.

8. Monitoring and Evaluation: Monitor the implementation of the new policies and evaluate their impact on improving access to maternal health. This can be done through regular data collection and analysis of ANC contacts and maternal health indicators.

By following this methodology, policymakers and stakeholders can assess the potential impact of the recommendations and make informed decisions to improve access to maternal health in Nigeria.
