Antenatal care (ANC) offers remarkable opportunities to reach a large number of women with effective nutrition and health interventions, including iron (Fe) supplementation. However, all women do not equally seek nor benefit from ANC. We aimed to identify characteristics associated with ANC and Fe use among women in hard-to-reach areas in Afar, Ethiopia; Sedhiou and Kolda, Senegal; and Kakamega, Kenya. Women who gave birth within 1 year preceding the survey (n = 4,575) from 15 different sub-regions were randomly selected and surveyed. Multivariable logistic regression was used to identify associations of socio-demographic characteristics with ANC and Fe use. Factors that showed positive associations with ANC uptake included education, income, possession of a mobile phone, and the occupation of the mother or another household member. Beginning ANC in the first trimester associated positively with achievement of 4 or more ANC visits, and having any ANC visits related positively with Fe intake. Distance to the nearest health facility was negatively associated, and type of nearest facility and counselling and health education were positively associated with some outcomes. The results from these surveys demonstrate the need to ensure access of services across all population groups and can help identify ANC programming needs.
The following methods summarize those applied in the baseline survey of the three countries. Further detail is provided by Kung’u, Pendame, et al. (2018) in this supplement. Cross‐sectional surveys were conducted in selected communities in each of the three countries. Mothers with children under 12 months were eligible to participate in the baseline surveys. The surveys included five sub‐counties of Kakamega County in Kenya: Kakamega Central, Matungu, Mumias, Butere, and Khwisero; six woredas, the third‐level administrative division of Ethiopia, in Afar regional state: Dewe, Telalak, Chifra, Aura, Ewa, and Gulina; and three departments in the Kolda region and one department in the Sedhiou region of Senegal: Kolda, Medina Yoro Foula, Velingara, and Sedhiou. All households where data were collected were in rural areas. A total of 4,575 women were surveyed: 1,969 in Ethiopia from April to June 2013, 682 in Kenya in February 2013, and 1,925 in Senegal in January and February 2014. A multistage cluster approach was used. The first stage began from the primary sampling unit of district in Senegal, woreda in Ethiopia, and sub‐county in Kenya, with villages and households selected in the second and third stages. The details of the sampling and sample size calculation are described elsewhere (Kung’u, Pendame, et al., 2018). Technical teams tailored a questionnaire to the local context in each country. Individuals with data collection experience were recruited and trained on interview techniques, supervision, administration of the questionnaires, and ethical consideration of participants. Training lasted 3 days in Kenya, 5 days in Ethiopia, and 2.5 days in Senegal. The questionnaires were finalized after pretesting in similar neighbouring communities. The University of Nairobi ethics and review board in Kenya, the Ethiopian Health and Nutrition Research Institute ethical clearance committee in Ethiopia, and the National Ethics Committee for Health Research in Senegal provided ethical approval prior to the survey. Informed consent was obtained from all participants and confirmed with a signature or a fingerprint. There were no personal identifiers on the data collection forms and all data were handled with strict security to ensure confidentiality. Data entry and the initial cleaning were done using EpiData Version 3.1 in Ethiopia, Epi Info 2000 in Senegal, and Microsoft Access version 14.0 in Kenya. In all countries, data were double entered by two different data entry clerks for quality assurance and data cleaning. Analyses were conducted using IBM SPSS version 23.0. The analysis involved logistic regression using four outcome variables (1 = yes, 0 = no). Three of the outcome variables related to uptake of ANC provided by a skilled health care provider, that is, an accredited health professional proficient in the skills needed to manage uncomplicated pregnancies, childbirth, and the immediate post‐natal period, and in the identification, management, and referral of complications in women and newborns as compared to an unskilled health care provider who has no formal training (WHO, 2004). These three outcome variables showed whether the women received ANC (a) at least once during pregnancy (Any ANC), (b) during her first trimester of pregnancy (FT ANC), and (c) four or more times during her pregnancy (≥4 ANC). In Senegal, FT ANC is not presented here as the data were collected only from women who could present their health card with their pregnancy information, which was inconsistent with the other countries and outcomes. The fourth outcome variable showed whether a woman took an iron supplement at least once during her pregnancy. In Ethiopia, women were asked specifically about iron supplements. In Senegal, they were asked about supplements containing both iron and folic acid, and in Kenya, they were asked whether they took iron alone or iron combined with folic acid. In each country, conceptual frameworks were developed independently, which identified characteristics believed to relate to mothers’ access and motivation to seek care during pregnancy. Analyses were guided by grouping of these characteristics: (a) maternal, (b) household, (c) birth history, (d) advice and counselling received during pregnancy, and (e) health service access. Bivariable logistic analysis was conducted for each independent variable and the outcome variable. For categorical variables, no category with less than 30 cases was retained. To develop a best‐fit multivariable model, all independent variables that showed significant relationships (p < .10) to an outcome variable, in the bivariable analysis, were entered in a logistic regression for that outcome. Using SPSS's backward step selection based on likelihood‐ratio tests, the best fit model was chosen for each outcome. The settings at each step of these processes were p = .10 for entry and p = .11 for removal.
