Predictors of women's utilization of primary health care for skilled pregnancy care in rural Nigeria.

BACKGROUND: Although Primary Health Care (PHC) was designed to provide universal access to skilled pregnancy care for the prevention of maternal deaths, very little is known of the factors that predict the use of PHC for skilled maternity care in rural parts of Nigeria - where its use is likely to have a greater positive impact on maternal health care. The objective of this study was to identify the factors that lead pregnant women to use or not use existing primary health care facilities for antenatal and delivery care. METHODS: The study was a cross-sectional community-based study conducted in Esan South East and Etsako East LGAs of Edo State, Nigeria. A total of 1408 randomly selected women of reproductive age were interviewed in their households using a pre-tested structured questionnaire. The data were analyzed with descriptive and multivariate statistical methods. RESULTS: The results showed antenatal care attendance rate by currently pregnant women of 62.1%, and a skilled delivery of 46.6% by recently delivered women at PHCs, while 25% of women delivered at home or with traditional birth attendants. Reasons for use and non-use of PHCs for antenatal and delivery care given by women were related to perceptions about long distances to PHCs, high costs of services and poor quality of PHC service delivery. Chi-square test of association revealed that level of education and marital status were significantly related to use of PHCs for antenatal care. The results of logistic regression for delivery care showed that women with primary (OR 3.10, CI 1.16-8.28) and secondary (OR 2.37, CI 1.19-4.71) levels education were more likely to receive delivery care in PHCs than the highly educated. Being a Muslim (OR 1.56, CI 1.00-2.42), having a partner who is employed in Estako East (OR 2.78, CI 1.04-7.44) and having more than five children in Esan South East (OR 2.00, CI 1.19-3.35) significantly increased the odds of delivery in PHCs. The likelihood of using a PHC facility was less for women who had more autonomy (OR 0.75, CI 0.57-0.99) as compared to women with higher autonomy. CONCLUSION: We conclude that efforts devoted to addressing the limiting factors (distance, costs and quality of care) using creative and innovative approaches will increase the utilization of skilled pregnancy care in PHCs and reduce maternal mortality in rural Nigeria.

Assessment of service readiness for maternity care in primary health centres in rural Nigeria: implications for service improvement.

INTRODUCTION: several scientific reports from studies across Nigeria revealed a higher incidence of maternal mortality in rural parts of the country as compared to the urban areas. Part of the reasons is the paucity of health care infrastructure and personnel. This study was designed as part of an intervention program with the goal to improve the access of pregnant women to skilled pregnancy care in rural Nigeria. The specific objective of the study was to determine the nature and readiness of Primary Health Centres (PHCs) in two Local Government Areas (LGAs) in rural parts of Edo State, Southern Nigeria to deliver effective maternal and child health services. METHODS: the study was conducted in 12 randomly selected PHCs in the two LGAs. Data were obtained with a semi-structured questionnaire administered on health workers and through direct observation and verification of the facilities in the PHCs. The results obtained were compared with the national standards established for PHCs in Nigeria by the National Primary Health Care Development Agency (NPHCDA). Descriptive statistics were used to analyze the data. RESULTS: the results showed severe deficits in buildings and premises, rooms, medical equipment, essential drugs, and personnel. Only 40% of items recommended by the NPHCDA were available for buildings; 41% of the PHCs had facilities available in the labour ward; while less than 30% had the recommended facilities in the antenatal care rooms. Only one PHC had a laboratory space, with only one item (a dipstick for urine analysis) identified in the laboratory. None of the PHCs had ambulances, mobile phones, internet or computers. There was no nurse/midwife in 4 PHCs; only one nurse/midwife each were available in 8 PHCs; while there was no Environmental/Medical Records Officer in any PHC. About 26% of the essential drugs were not available in the PHCs. CONCLUSION: we conclude that PHCs in Edo State, Nigeria have severe deficits in infrastructural facilities, equipment, essential drugs and personnel for the delivery of maternal and child health care. Efforts to improve these facilities will help increase the quality of delivery of maternal and child health, and therefore reduce maternal and child mortality in the country.

Human dietary exposure to chemicals in sub-Saharan Africa: safety assessment through a total diet study.

BACKGROUND: Human dietary exposure to chemicals can result in a wide range of adverse health effects. Some substances might cause non-communicable diseases, including cancer and coronary heart diseases, and could be nephrotoxic. Food is the main human exposure route for many chemicals. We aimed to assess human dietary exposure to a wide range of food chemicals. METHODS: We did a total diet study in Benin, Cameroon, Mali, and Nigeria. We assessed 4020 representative samples of foods, prepared as consumed, which covered more than 90% of the diet of 7291 households from eight study centres. By combining representative dietary surveys of countries with findings for concentrations of 872 chemicals in foods, we characterised human dietary exposure. FINDINGS: Exposure to lead could result in increases in adult blood pressure up to 2·0 mm Hg, whereas children might lose 8·8-13·3 IQ points (95th percentile in Kano, Nigeria). Morbidity factors caused by coexposure to aflatoxin B1 and hepatitis B virus, and sterigmatocystin and fumonisins, suggest several thousands of additional liver cancer cases per year, and a substantial contribution to the burden of chronic malnutrition in childhood. Exposure to 13 polycyclic aromatic hydrocarbons from consumption of smoked fish and edible oils exceeded levels associated with possible carcinogenicity and genotoxicity health concerns in all study centres. Exposure to aluminium, ochratoxin A, and citrinin indicated a public health concern about nephropathies. From 470 pesticides tested across the four countries, only high concentrations of chlorpyrifos in smoked fish (unauthorised practice identified in Mali) could pose a human health risk. INTERPRETATION: Risks characterised by this total diet study underscore specific priorities in terms of food safety management in sub-Saharan Africa. Similar investigations specifically targeting children are crucially needed. FUNDING: Standards and Trade Development Facility.

Methodology design of the regional Sub-Saharan Africa Total Diet Study in Benin, Cameroon, Mali and Nigeria.

The core food model was described more than three decades ago, and has been used ever since to identify main food contributors to dietary intakes for both nutrients and other food chemicals. The Sub-Saharan Africa Total Diet Study (SSA-TDS) uses this model to describe the food consumption habits of some selected populations of Benin, Cameroon, Mali, and Nigeria, prior to use in the completion of quantitative risk assessments with regard to food chemicals. Food consumption data were derived from food expenditure data contained in national household budget surveys that were provided by the national institutes of statistics in each country. A classification of African foods was established for the purpose of the study and core foods were selected, so as to reflect 96 ± 1% of the average national total diet expressed in weight. Populations from eight study centers were selected by national stakeholders. This approach involves the purchase of 4020 individual foods, prepared as consumed and pooled into 335 food composite samples, for analysis of mycotoxins, PAHs, PCBs and dioxins, pesticides, metals and trace elements, PFAs, and BFRs. This sampling plan aims to provide a representative, cost effective, and replicable approach for deterministic dietary exposure assessments in developing countries.
