Distribution of the adolescent mothers
Table 1 shows the distribution of adolescent mothers with respect to the study variables. More than half of the adolescent mothers (56%) were older adolescents aged 18-19 years. Half of the adolescent mothers (51%) were pregnant at the time of the study. Adolescent mothers who had ever given birth constituted 49% of all adolescent mothers in this study. Of these, almost nine out of ten (86%) had given birth to one child. Majority (89%) of the adolescent mothers were younger than their partners. All adolescent mothers in this study had attained a certain level of education. Close to three quarters of the mothers (72%) had attained primary level as their highest level of education. In this study, six out of ten (60%) adolescent mothers were either married or in a union as if married (cohabiting).

Note: 1 One adolescent mother (0.4%) belonged to no religion
With regard to religion, nearly three quarters (72%) of the adolescent mothers were Christians. Most of the adolescent mothers were currently living with their partners or father of the child (61%) and reported having received no social support during their most recent pregnancy or birth (65%). The majority (80%) of adolescent mothers reported earning no daily income. This is not surprising since the highest proportion (68%) of the adolescent mothers were not working.
Notably, most adolescent mothers in this study stayed quite far away from the nearest health facility. Almost 4 out of 5 (72%) adolescent mothers were staying one kilometer away from the nearest health facility. Most of the adolescent mothers made their own decisions regarding seeking health care. The results in Table 1 show that more than two fifths (46%) of the adolescent mothers made their own decisions on seeking health care. However, a similar proportion of the adolescent mothers had their decisions on seeking health care made by other people (26% by husbands/partners and 20% by relatives/in-laws). Furthermore, slightly more than half of the mothers (51%) had mistimed pregnancies. That is, they did not want to get pregnant at the time they conceived their current pregnancy or the pregnancy for their most recent birth.
Knowledge about pregnancy danger signs and family planning methods
The results presented in Figure 1 show the distribution of adolescent mothers by their knowledge about obstetric pregnancy danger signs and family planning methods. Adolescent mothers who were knowledgeable about pregnancy danger signs and family planning methods constituted the majority (83% and 91% respectively).
Utilization of ANC
Table 2 presents results on utilization of ANC by the adolescent mothers. ANC attendance among adolescent mothers was high. Overall, the majority (82%) of the adolescent mothers attended ANC for their most recent pregnancy or birth. However, more than half (53%) did not complete the recommended minimum of four visits, with 13% attending ANC once, 16% attending twice and 24% attending thrice. Only 22% of adolescent mothers who attended ANC completed the recommended minimum number of four visits while slightly more than a quarter (26%) made more than the recommended four ANC visits. The results in Table 2 further indicate that almost all adolescent mothers who attended ANC during their last pregnancy or birth received ANC from a government facility (91%) and from a skilled provider (98%). However, majority of the adolescent mothers delayed their first ANC visit. More than half (53%) of those who went for ANC made their first visit after the first trimester. This is further supported by the finding that adolescent mothers who attended ANC made their first ANC visit half way through the gestation period since the median gestation age, at the time they made the first ANC visit, was four months.

Components of the ANC visit received
The components of the package of care for pregnant women who attend ANC include a set of WHO recommended services such as: - blood pressure measurement, urine and blood sample testing, weight measurement, tetanus vaccination, giving pregnant women iron tablets/syrup, drugs for intestinal worms and intermittent preventive treatment (IPTp) of malaria by giving pregnant women Sulfadoxine-Pyrimethamine (SP) (World Health Organization, 2016). Receipt or uptake of these services informs the quality of ANC received by women who attend ANC. The results presented in Figure 2 show the percentage of adolescent mothers (those that attended ANC during their current pregnancy or the pregnancy for their most recent birth) who received each of these services. The majority of the adolescent mothers had their blood sample drawn (96%), weight measured (86%), received a tetanus injection (88%) and received or were able to buy themselves iron tablets/syrup (87%). More than three quarters (78%) of the adolescent mothers had their blood pressure measured while seven out of ten mothers (70%) had their urine samples taken. Nearly three quarters (74%) of the adolescent mothers took antimalarial drugs during their current pregnancy or the pregnancy for their most recent birth and close to two thirds (65%) took drugs for intestinal worms.
Figure 3 below presents the percentage distribution of adolescent mothers who attended ANC by the number of ANC components of care received during those visits. The results were based on a nine-item index ranging between zero and eight. The index was adapted from a study by [19]. Items including whether the mother had her blood pressure and weight measured, urine and blood samples taken, received a tetanus injection, received iron tablets, took drugs for intestinal worms and SP/Fansidar drugs comprise the index. On the index, zero indicates all adolescent mothers who received none of the components during their ANC visit (None) while eight indicates adolescent mothers who received all the components (All). As per the WHO guidelines, it is expected that pregnant women should receive all the recommended components of the package of care when they attend ANC. For the recommended components of the package of care considered in this study, the results in Figure 3 show that almost all (97%) adolescent mothers who attended ANC received at least one of the components during ANC visits for their current pregnancy or most recent birth. However, receipt of all the recommended components of care was low with slightly more than one third (36%) of the adolescent mothers who attended ANC reporting receipt of all the components. Important to note is that there was a small proportion of adolescent mothers (3%) who attended ANC and yet did not receive any of the recommended components of care. On average, adolescent mothers who attended ANC received five components out of all the recommended eight components.
Factors associated with receipt of the recommended components of the ANC visit and timing of the first ANC visit
Table 3 presents results on the association between the independent variables and the outcome variables. The results indicate that having ever given birth (p<0.05) and having knowledge about the pregnancy danger signs (p<0.05) were the only factors significantly associated with receipt of the recommended components of the ANC visit. A significantly higher proportion (60%) of mothers who received all the ANC components were mothers who had ever given birth. Similarly, the majority (93%) of adolescent mothers who received all the recommended components during their ANC visit were mothers who knew about the obstetric pregnancy danger signs.

Note: 1 Components of the ANC visit; 2 HF = Health facility; * Significant at p<0.05
However, partner’s age, ever given birth, marital status, partner presence, working status, daily earnings and knowledge about obstetric pregnancy danger signs (p<0.05) were the only factors significantly associated with timing of the first ANC visit (Table 3). Almost all mothers (97%) who made the first ANC visit in the first trimester were younger than their partners in terms of age. Majority of the mothers who made the first ANC visit in the first trimester were those who had never given birth while three fifths (60%) of mothers who made the first ANC visit after the first trimester were those who had ever given birth to a child. More than two thirds of mothers (67%) who made the first ANC visit in the first trimester were married or cohabiting. Similarly, this group of mothers constituted the majority (53%) among those who made the first visit after the first trimester. Mothers staying with their partners constituted the majority of those who made the first ANC visit in the first trimester as well as after the first trimester. About seven in ten mothers (71%) who made the first visit in the first trimester and more than half (52%) of those whose first visit was after the first trimester were mothers staying with their partners or father of the child. More than three quarters (78%) of mothers who made the first ANC visit after the first trimester were not working and were not earning any money (91%). Out of every ten adolescent mothers who made their first visit in the first trimester, nine were knowledgeable about or aware of the obstetric pregnancy danger signs.
Determinants of timing of first ANC visit and Receipt of components of the ANC visit
Multivariate analysis results from Binary logistic regression, on factors associated with - an adolescent mother receiving all the components of the ANC visit and timing of the first ANC visit are presented in Table 4 and Table 5, respectively. From the bivariate analysis, partner’s age, ever given birth, partner presence, daily earnings and knowledge of obstetric pregnancy danger signs were significantly associated with utilization of ANC. Marital status and working status were also significantly associated with utilization of ANC at bivariate analysis level. However, these were excluded from the regression models, along with children ever born, religion and provider cadre due to multicollinearity. Partner presence was considered over marital status because of the following reason. Partner presence is associated with physical support for the adolescent mother in terms of – escorting her to the health facility for ANC, reminding her about the next ANC visit and reminding her to swallow (if necessary) drugs during pregnancy. However, being married or in-union does not imply that the partner is always present. There is evidence that adolescent mothers are more likely to be rejected by partners [26]. There is a possibility that this could negatively affect their uptake of health services including ANC. This makes partner presence a more important variable to investigate than just marital status. Similarly, daily earning was considered over working status because of the following reason. Financial constraints have implications for the uptake of health services [26]. Without money, meeting transport costs to the health facility or even purchasing health commodities such as drugs may be challenged. Furthermore, adolescent mothers are less likely to find a decent paying job. This implies they are highly likely to be financially constrained. It is therefore possible that being financially constrained could hinder them from utilizing ANC services. Variables including mother’s age, mother’s education level, distance to nearest health facility, social support, decision maker on seeking health care, pregnancy wanted (intendedness of pregnancy), and type of health facility were included in the regression analysis even though they were not significant at bivariate level. This is because of their documented importance, in literature, in influencing ANC utilization. The regression models contained thirteen variables including - Adolescent mother’s age, partner’s age, ever given birth, education level, partner presence, distance to health facility, social support, decisions on health care, pregnancy wanted, daily earnings, knowledge of pregnancy danger signs, knowledge of family planning methods, type of health facility.
Determinants of receipt of all components of the ANC visit
As shown in Table 4, distance to nearest health facility, knowledge of obstetric pregnancy danger signs and knowledge of family planning methods were the only statistically significant factors associated with receipt of components of the ANC visit for adolescent mothers. The odds of receiving all components of the ANC visit were lower for mothers staying at least one kilometer away from the nearest health facility (OR=0.424, P=0.038, CI: 0.189, 0.952) compared with those staying less than one kilometer away. Similarly, mothers who had knowledge on family planning methods had lower odds of receiving all components of the ANC visit (OR=0.262, P=0.047, CI: 0.070, 0.982) compared with those who had no such knowledge. Mothers who were knowledgeable about the obstetric pregnancy danger signs were found to be 6.6 times more likely to receive all components of the ANC visit (OR=6.567, P=0.005, CI: 1.750, 24.648) compared with those who were not knowledgeable about these signs.

Determinants of timing of the first ANC visit
Results presented in Table 5 show that, adolescent mother’s age, partner’s age, ever given birth, decision maker on seeking healthcare, daily earnings and knowledge of obstetric pregnancy danger signs were the only factors statistically significantly associated with timing of the first ANC visit. The odds of making the first ANC visit after the first trimester were highest for mothers who had ever given birth and those whose decisions on seeking health care were made by relatives or in-laws. Mothers who had ever given birth were 3.7 times more likely to go for the first ANC visit after the first trimester (OR=3.669, P=0.001, CI: 1.678, 8.023) compared with mothers who had never given birth. Compared with mothers whose decisions on seeking health care were made by themselves, mothers whose decisions on seeking health care were made by relatives or in-laws were 3.4 times more likely to make the first ANC visit after the first trimester (OR=3.449, P=0.043, CI: 1.041, 11.424). Older adolescent mothers (18-19 years) were less likely to make the first ANC visit after the first trimester (OR=0.471, P=0.046, CI: 0.224, 0.987) compared with the young mothers (Below 18 years). Mothers who were younger (14-17 years) than their partners had lower odds of making the first ANC visit after the first trimester (OR=0.231, P=0.041, CI: 0.056, 0.942) compared with those whose age was the same as their partner’s. The odds of going for the first ANC visit after the first trimester were lower for mothers who earned some money from their work (OR=0.254, P=0.004, CI: 0.099, 0.653) compared to those who earned nothing. Similarly, having knowledge of the obstetric pregnancy danger signs was associated with lower odds of making the first ANC visit after the first trimester (OR=0.346, P=0.043, CI: 0.124, 0.966) compared to having no such knowledge.
