The risk of having ANC insufficiency was found in women who had recently given birth in the 20 to 24 age group (OR = 0.67) and those over 40 years of age (OR = 0.66). The same observation was made among women who had given birth with a Qur’anic level of education (OR = 191.67) and those with no level of education (OR = 145.40). The mothers surveyed (OR = 1.46) were more vulnerable to ANC insufficiency. Common-law women who had recently given birth had a significant risk of ANC insufficiency (OR = 95.77). Those living in villages in the Gbêkê region had a risk of ANC insufficiency (OR = 5.10) (Table 1).

Table 1. Socio-demographic profile of women who have given birth.

First-time patients in 33.5% of cases compared to 14.78% in controls, had an insufficiency of ANC with a risk of 5.48. As for first-time mothers, this risk was 7.94 (Table 2).

Table 2. Obstetric history of women who have given birth.

Newborns who had their first ANC late or in the second trimester had a risk of around 16 to ANC insufficiency. For those in financial difficulty, this risk was 27.68. Mothers who used public transport had a 1.52 risk of ANC insufficiency. This risk was found at 0.52 in postpartum women who had no knowledge of prenatal consultation (Table 3).

Table 3.Prenatal follow-up of women who have given birth.

Financial difficulties in 43.84% of cases were the main reason for women who had given birth and had insufficient prenatal consultations (Table 4).

Table 4. Reasons for ANC deficiency.

Our study revealed limitations, on the one hand the single-center conception (taking place at the Bouaké University Hospital) which could affect the generalization data and on the other hand the possibility of recall bias among our women surveyed who reported their history of prenatal care.

In our study, 85.78% of the women who gave birth had started their prenatal consultation late. This result was higher than that reported by Oussou [7] (61.3%) in Côte d’Ivoire. The low involvement of the pregnant woman in the decision-making process in the family, the lack of accurate and relevant information or awareness on the advantages of prenatal consultation for the mother-child couple, especially the unfavorable socio-economic and cultural conditions, are all factors that could justify this high prevalence of delayed and insufficient prenatal consultation at the Bouaké University Hospital.

The 20 and 24 age group accounted for 25.61% of cases and 22.17% of controls. The risk of having ANC insufficiency was high for women who gave birth between 20 and 24 years of age, respectively (OR = 0.67; 95% CI: 0.33 - 1.35) and those aged 40 years and older (OR = 0.67; 95% CI: 0.31 - 1.48). This risk could be explained by several factors: their single status, financial difficulties. The shame for those over 34 years of age to continue their reproductive life [2]. Our results showed that 54.18% of the cases and 7.14% of the controls were without education. This result was similar to that of Traore [8], who found that 62.9% of women had no level of education. This low enrolment rate was associated with a high risk of ANC among postpartum mothers with a Qur’anic level of education (OR = 191.67; 95% CI: 66.58 - 551.75) and those not in school (OR = 145.40; 95% CI: 58.65 - 360.48). This high proportion of women who are not in school in our study can be explained by several factors, including their origin, mainly from the villages of the Bouaké region for their births at the University Hospital, and their precarious socio-economic conditions.Traoré [8] stated that an uneducated patient understands less well the importance of prenatal consultations. Lack of schooling is an obstacle to the acquisition of knowledge about the advantages of early prenatal consultation. Educational attainment provides a better understanding of health issues in general when they are the subject of awareness, which is necessary for the adoption of appropriate health behaviour. Unfavorable socio-economic conditions with low financial autonomy were associated with insufficient ANCs in our work. The frequency of unemployed or housewives was 34.48% in cases

compared to 40.64% in controls. The number of unemployed women with important domestic activities leaves little time for prenatal follow-up [8]. The risk of having ANC insufficiency was high in male and female students (OR = 1.46; 95% CI: 0.80 - 2.68). This situation could be explained by the fact that these women generally had more common-law pregnancies in our region, in particular. Female births living in common-law unions or alone accounted for 52.71% and 8.86% of cases and controls, respectively. This rate was comparable to that of Kochou [9] in Côte d’Ivoire, which found 54.9% of women in common-law unions with a high risk of having ANC insufficiency (OR = 95.77; 95% CI: 44.64 - 205.47). On the other hand, Ekou [10] in Abobo Baoulé (Abidjan) found 67% of pregnant women living in couples. There are many reasons for this common-law marital situation in our region, including a lack of family and partner support, poverty, and traditional beliefs or cultural practices surrounding pregnancy, which must be kept secret to avoid bad spells. There is a need for considerable efforts to reduce this cultural influence on antenatal care attendance. Newborn women living in the villages of the Gbêkê region accounted for 55.17% of cases compared to 13.79% of controls. Those from the city of Bouaké represented 30.54% of cases against 67.98% of controls. Ndiaye [2] in Senegal found that 68% of women living in rural areas had their ANC1 late and 33% of women living in rural areas had done so early. We found a risk of ANC insufficiency in postpartum women living in villages in the Gbêké region (OR = 5.10; 95% CI: 2.99 - 8.72). Rural populations are sometimes poorer than urban populations and the supply of health services is more diversified in urban areas than in rural areas, degraded road infrastructure complicates the transport or quick and easy transfer of women, and means of transport are expensive and not permanently available. A study in Sudan reported that women who did not use antenatal care services were those with less education and living in rural areas [11].

The frequency of primiges was 33.5% in cases compared to 14.78% in controls. First-time primigicans had a higher risk of ANC insufficiency (OR = 5.48; 95% CI: 3.24 - 9.26). Our result was contrary to that of Oussou [7] who reported that multi-gestures had a greater risk of delay and insufficiency at the prenatal consultation.First-time mothers who are unaware of the risks associated with pregnancy may be reluctant to use antenatal care services early. First-time mothers had a higher risk of ANC insufficiency (OR = 7.94; 95% CI: 4.73 - 13.33). The frequency of primiparous cows was 48.28% in cases compared to 18.72% in controls. This result was similar to that of Oussou [7] (46.5%) and could be explained by the fact that they did not have a good knowledge of the benefits of using the antenatal consultation. Our observations concerning pregnancy and parity were contrary to that of N’dri K [12] in Kouiby, Côte d’Ivoire, who found that most of the respondents who were late in prenatal consultations had at least two pregnancies (88%) and at least two deliveries (65%).

Newborns who had their first ANC in the second trimester of pregnancy accounted for 57.14% of cases and 19.27% of controls. This result was lower than that reported by Mafuta [13] in Congo, who found 69.2% of women who had their first ANC in the second trimester of pregnancy. Our observation was contrary to that of Yéo [14] who found that 68% of pregnant women had made their first prenatal care visit early in the Djébonoua health area in Côte d’Ivoire. The risk of having an insufficiency of ANC for postpartum women who had their ANC in the 2nd trimester of pregnancy was (OR = 16.82; 95% CI: 10.45 - 27.07). Ignorance of pregnancy-related complications is a risk factor for ANC insufficiency. Raising awareness of the role of early antenatal care in preventing life-threatening diseases of the fetus and mother will contribute to a change in women’s behaviour in the first antenatal consultation. The risk of having ANC insufficiency in postpartum women whose reason was financial problem was (OR = 27.68; 95% CI: 17.55 - 43.66). The reason for not performing the prenatal check-up was financial problems in 85.71% of cases and 14.78% of controls. Since the decisions of pregnant women are significantly influenced by their husbands, strategies should be developed to raise awareness among their spouses in order to increase their adherence to the NPC. Newborns who had no or insufficient knowledge of the benefits of using ANCs accounted for 67% of cases and 17.24% of controls. The risk of having ANC insufficiency was high for postpartum women who knew nothing about ANC (OR = 10.51; 95% CI: 5.81 - 19). More frequent and better consultations for all women during pregnancy will facilitate the application of preventive measures and the early detection of risks, avoid complications as much as possible and help to address health inequalities [15].

Female births whose reason for ANC insufficiency was the financial problem represented 43.84% of cases. This result was comparable to that of Mafuta [13], which found that 67.9% of women who attended antenatal care services late in life had financial difficulties. According to Niang [11], although there are exemptions from fees for the use of health services in most countries in sub-Saharan Africa, the result is that care costs still remain an issue for users.
