Teenage pregnancy and childbearing present a paradox in many parts of Sub-Saharan Africa. Although many cultures do not approve of premarital teenage sexuality and pregnancy, they still sanction early marriages, which are associated with increased coital frequency and decreased condom use, and hence increased chances of early child- bearing.1–3 Early marriage is becoming less frequent in many countries in the region; however, these declines are shifting the context of sexual initiation from marital to premarital sex.3–6 Compared with other regions of the world, Sub-Saharan Africa continues to have the greatest proportion of teenagers who are mothers.3,7–9 At the same time, perhaps because of the cultural view of premarital teenage sexuality and pregnancy and the weakness of health care systems in general, reproductive health services in most cases do not adequately meet the needs of adolescents, including teenage mothers.10–12

A number of studies in the developed and developing world have documented worse maternal and child health outcomes among teenage mothers than among older mothers, including increased risks of preterm delivery, low birth weight, neonatal mortality and late spontaneous or induced abortions. This disparity has been attributed to teenagers' physiological immaturity, lower use of prenatal and delivery care services, lower socioeconomic status and higher rates of unintended pregnancy.13–21 These disadvantages are likely to be exacerbated in low-resource contexts such as Sub-Saharan Africa; indeed, profound disparities exist even in urban areas with relatively good health care services.19,20,22–24

The high HIV prevalence in parts of Sub-Saharan Africa further complicates the reproductive health outcomes of pregnant teenagers: Obtaining access to relevant services, such as prenatal care, skilled attendance and prevention of mother-to-child transmission (PMTCT) of infection, is likely more difficult. Because of their age, teenage mothers may have to deal with disapproving health care providers; in addition, those living with HIV may face stigma and discrimination in health care settings.25,26 Nonetheless, with the increased availability of antiretroviral treatment and emphasis on treatment, care and prevention, maternal and child health outcomes should improve for HIV-positive women, including adolescents. However, emerging evidence indicates that the existing HIV/AIDS treatment, care and support programs in the region do not ask their adolescent clients about their sexual and reproductive health needs because most service providers advise these clients to refrain from or postpone sexual intercourse.27–29 This represents a missed opportunity for systematically identifying and addressing the reproductive health concerns of HIV-positive adolescent clients.

Given the poor maternal and child health outcomes of adolescents in the region, it seems reasonable to assume that pregnant, HIV-positive teenagers have difficulty obtaining access to appropriate maternal health services. However, research in this area is limited. Using unique pregnancy history data collected from HIV-positive adolescent females who were receiving treatment, care and support services from various HIV/AIDS programs in four regions of Kenya, this article examines the use of maternal health care services by this subset of the population. First, we describe the distribution of pregnancies among HIV-positive adolescents by maternal background characteristics and use of health care services. Subsequently, we examine the variables associated with maternal health care use in the group of HIV-positive adolescents, with specific focus on prenatal care, PMTCT services, skilled attendance and postnatal care.



The data are from a study conducted in 2009 among HIV-positive male and female adolescents aged 15–19 in the regions with the highest HIV prevalence in Kenya—Nyanza, Nairobi, Rift Valley and Coast provinces. Among 15–49-year-olds, the HIV prevalence in these regions is 14%, 7%, 5% and 4%, respectively, while prevalence among 15–19-year-olds is 5.8%, 0.3%, 0.7% and 0.8%. In Kenya overall, HIV prevalence is 6.3% among adults and 1.7% among adolescents.30

The study involved a quantitative survey and qualitative interviews with HIV-positive adolescents who were aware of their serostatus and were willing to participate, as well as focus group discussions with a subset of the same participants and unstructured interviews with providers working with this population. The participants were identified and recruited through existing programs for orphaned and vulnerable children, comprehensive care centers, youth counseling centers and voluntary counseling and testing centers in the four provinces. Most centers were located in urban and periurban areas although many, especially those in periurban areas, served clients from rural areas as well. Service providers (counselors, community health care workers and social workers) who interacted with the adolescents helped identify respondents. Written consent was obtained from participants before interviews were conducted. For adolescents aged 15–17, written consent was obtained from their parent or guardian and then from the adolescents themselves. For those aged 18–19 and those aged 15–17 who were living alone, married or taking care of siblings, only individual written consent was obtained. Ethical and research clearance for the study was granted by the institutional review board of the Population Council, the Research Ethics Committee of the Royal Tropical Institute, the Ethics Review Committee of the Kenya Medical Research Institute and the Kenya National Council for Science and Technology.

This article uses only the data from the quantitative survey, in which structured interviews were conducted by research assistants aged 18–24 who had received training on study procedures, data collection and research ethics. The survey tool was adapted from one used for a similar study in Uganda.27 It was then translated into Kiswahili (Kenya's national language) and Dholuo, the dominant language spoken in Nyanza province. The interview setting was agreed on by the research assistant and the respondent.

The survey collected information on respondents' background characteristics, highest level of education (no schooling, primary school, and secondary school and above), access to information and support services, ?relationships and dating, sexual behavior and desires, knowledge and use of contraceptive methods, age at first pregnancy (in single years), pregnancy history and child- bearing experiences, experiences of physical and sexual violence, whether the respondents felt they were discriminated against because of their serostatus (perception of stigma) and issues of self-esteem.

A total of 1,070 HIV-positive adolescents were identified as eligible to participate in the study, and interviews were completed with 1,059 individuals. Of the 11 adolescents who did not complete interviews, one declined, and the remaining were unable to continue because of emotional breakdown or were still unaware of or in denial about their serostatus.

The number of female respondents who completed the survey was 757. Of these, 77% (586) had ever had sexual intercourse. Three hundred and ninety-three of those who had ever had intercourse had been pregnant, while 24% (95) of those who had been pregnant had experienced multiple pregnancies. The total number of pregnancies reported was 506; for each pregnancy, respondents were asked detailed questions on whether it was intended, the relationship to the man who was responsible (husband, boyfriend, fiancé, friend, acquaintance or stranger), use of prenatal care services, the outcome, the place of delivery or pregnancy termination, and use of family planning after delivery or pregnancy termination. Use of maternal health care services was measured by five dichotomous outcomes—receiving prenatal care; making four or more prenatal care visits (0–3, ≥4); receiving PMTCT services; receiving skilled assistance (being assisted by a doctor, nurse or facility midwife during delivery or induced or spontaneous abortion); and receiving postnatal/postabortion care services.


The data are hierarchical, and pregnancies are clustered within individual adolescent mothers identified from the same HIV/AIDS treatment, care and support facility. The nature of the data requires an analysis technique that accounts for unobserved characteristics of pregnancies to the same mother as well as of individuals identified from the same facility. The analysis therefore entails estimation of random-intercept multilevel logit models using Stata31 to predict use of maternal health care services.*

The first two models include as covariates the age at first pregnancy, study site, the highest level of education of the mother, pregnancy order, relationship to the man who was responsible for the pregnancy, an indicator of whether the respondents felt they were discriminated against because of their serostatus (perception of stigma) and whether the pregnancy was intended. In addition to these, the next three models include prenatal care visits as a control.


Characteristics of the Sample

Because the HIV-positive adolescents participating in the study are likely to differ from adolescents in the general population, we provide data from the Kenya Demographic and Health Survey (DHS) on adolescents from the four regions covered in our study to provide a basis for comparison (Table 1, page 144). The majority of the adolescents in the HIV-positive sample were aged 18–19 at the time of the survey (65%), lived in Nairobi or Nyanza provinces (62%) and had a primary education (68%). Twelve percent were married or living with their partner. On average, the sample of HIV-positive adolescents was older than the DHS sample and were more likely to live in Nairobi or to be married or living with a partner; they were less likely to live in the Rift Valley.

Pregnancies to HIV-Positive Adolescents

The majority of current or previous pregnancies in our sample were reported by adolescents aged 18 or older at the time of the survey (85%—Table 2, page 145). In addition, nearly three-quarters (73%) of the pregnancies had occurred among adolescents in Nyanza and Nairobi, which have the highest rates of HIV in the country. The majority of pregnancies (71%) were reported by those with primary-level education. Nearly three-quarters (74%) of the pregnancies were reported by adolescents who were not married or living with their partner at the time of the survey.

Although most of the pregnancies were reported by adolescents aged 18 or older at interview, the majority had occurred when the respondents were younger. For instance, 79% of the pregnancies reported had occurred among young women who had experienced their first pregnancy before age 18. That 74% of the pregnancies to HIV-positive adolescents occurred among those who were not married or cohabiting at the time of the survey and that people other than husbands were responsible for 75% of the pregnancies indicates that the majority of these pregnancies occurred outside of marriage. In addition, nearly three-quarters (74%) of the pregnancies among HIV-positive adolescents were unintended.

Although the adolescents received prenatal care in 84% of their pregnancies, they made four or more visits during only 45% of the pregnancies. In addition, despite the fact that the provision of PMTCT services to HIV-positive adolescents should be part of prenatal care, the proportion of pregnancies for which these mothers received PMTCT services was significantly lower than the proportion for which they received prenatal care (67% vs. 84%; p&;.01, not shown). A similar pattern appeared among HIV-positive female adolescents who were still pregnant at the time of the survey: They received prenatal care in 89% of pregnancies, while they received PMTCT services in only 74% of their pregnancies.

Most of the pregnancies resulted in a live birth (85%); in 5% of cases, the adolescent was still pregnant (Table 2). The proportion of pregnancy outcomes for which adolescents received skilled attendance was significantly lower for miscarriages, stillbirths or abortion than for full-term or preterm live births (20% vs. 79% and 78%, respectively; p&;.01, not shown). A similar pattern was observed for the proportion of pregnancy outcomes for which these adolescents received postnatal/postabortion care—33% for miscarriages, stillbirths or abortion, 89% for full-term and 85% for preterm live births. HIV-positive adolescents received skilled care during delivery or pregnancy termination and postnatal/postabortion care for 73% and 83% of the pregnancies respectively (Table 2).

Prenatal Care and PMTCT Services Utilization

The odds of receiving prenatal care services were significantly lower among HIV-positive adolescents in Coast province than among those in Nyanza province (odds ratio, 0.3—Table 3) and for adolescents having higher-order pregnancies than for those having lower-order pregnancies (0.5). HIV-positive adolescents were more likely to have received prenatal care when the man responsible for the pregnancy was their husband than when it was some other person (3.7). However, adolescents from Coast province were significantly more likely than their counterparts from Nairobi province to have made four or more prenatal care visits (p&;.05; not shown). In addition, HIV-positive adolescents were less likely to have made four or more visits for higher-order pregnancies than for lower-order pregnancies (0.4).

HIV-positive adolescents from Nairobi had higher odds of receiving PMTCT services than those from Nyanza (odds ratio, 3.8), as well as those from Coast (p&;.05; not shown) or Rift Valley provinces (p<.01; not shown). Adolescents were significantly less likely to have received PMTCT services for higher-order pregnancies than for lower-order pregnancies (0.4). However, they had higher odds of receiving PMTCT services when the person responsible for the pregnancy was their husband than when it was somebody else (4.9). Overall, adolescents were more likely to receive PMTCT services if they had made at least four prenatal care visits than if they had not (6.5).

Skilled Assistance and Postnatal/Postabortion Care Utilization

HIV-positive female adolescents from Nairobi were more likely to have received skilled assistance than their counterparts from Nyanza province (odds ratio, 2.7—Table 4) or Coast province (p&;.05; not shown). Overall, the odds of having received skilled care decreased as birth order increased (0.6). However, adolescents had significantly higher odds of receiving skilled assistance if they had made at least four prenatal care visits than if they had made fewer (4.7).

The odds of HIV-positive adolescents receiving postnatal/postabortion care services were significantly lower in Coast and Rift Valley provinces than in Nyanza (odds ratio, 0.2 each). However, mothers who had made four or more prenatal care visits had higher odds of receiving postnatal care services than those who had made fewer visits (5.1).


One of the major findings of this study is that the proportion of HIV-positive female adolescents who used PMTCT services was lower than the proportion who obtained prenatal care, despite national and international guidelines emphasizing the provision of such services to HIV-positive mothers as an integral component of prenatal care.32,33 One explanation could be the low proportion of adolescent mothers who made four or more prenatal care visits, given that this was associated with higher odds of receiving PMTCT services. It is possible that providers are able to offer more comprehensive services to those who make more frequent prenatal visits, given that not all services can be offered during one visit. Another explanation could be the lower odds of seeking care, including PMTCT services, for higher-order pregnancies than for lower-order pregnancies among adolescent mothers in the study. The high proportion receiving any prenatal care, the low proportion making four or more prenatal care visits, and the lower odds of seeking care for higher-order births have been observed among women in general.19,23,30 For HIV-positive women, however, nonuse or underuse of prenatal care has implications for vertical transmission of HIV. Our finding suggests that there is a need to ensure that PMTCT services are designed to meet the needs of HIV-positive adolescent mothers. There is evidence that HIV programs in many parts of Sub-Saharan Africa are organized around pediatric or adult care; too little attention is paid to meeting the reproductive health needs of those making the transition from childhood to adulthood. It also suggests that more effective information, education and communication programs are needed to encourage expectant mothers to make at least the four prenatal care visits recommended in national and international guidelines.

The second major finding of the study is the low use of certain maternal health care services, especially skilled attendance and postnatal/postabortion care for pregnancies that ended in miscarriage, stillbirth or abortion among HIV-positive female adolescents. This finding suggests that most of these outcomes occur under unsafe conditions, thereby exposing the adolescents to increased risks of maternal morbidity and mortality. However, this is not unique to HIV-positive adolescents. Unsafe abortion practices have been documented among female adolescents in Sub-Saharan Africa who are not HIV-infected.18,34 How-ever, HIV-positive adolescents who receive treatment, care and support services visit clinics regularly. Ideally, these visits offer an opportunity to systematically screen HIV-positive young women for sexual and reproductive health information and service needs. Doing so will allow for early identification of pregnancy so that the adolescents can be referred to appropriate services. This finding also suggests the need for creating effective linkages between the HIV/AIDS centers and maternal and child health clinics to ensure comprehensive service provision for HIV- positive, pregnant adolescents.

The findings further suggest that to strengthen maternal and child health care services for this population, program planners need to take into account parity, paternity dynamics and regional variations in service use. Also, the finding that HIV-positive adolescent mothers from Nairobi were significantly more likely to receive PMTCT services and skilled attendance during delivery or pregnancy termination could be indicative of greater service availability and accessibility (in terms of distance from a facility and time needed to obtain the services) in the city than in other areas.

Our findings may be influenced by the study's limitations. First, the sample of HIV-positive adolescents was not randomly selected from the population. This was largely because of the sensitive nature of the study. Identifying and recruiting respondents through HIV/AIDS programs provided a convenient way of contacting them without exposing them to harm, psychological or otherwise. However, given the low rates of enrollment in HIV care and treatment in many East African settings,35,36 their experiences may not reflect the experiences of all HIV-positive adolescents in Kenya. The observed levels of maternal health care utilization could be higher or lower, depending on how different they are from their counterparts who do not receive services from the centers. In addition, the study did not capture information on other factors that might affect access to and utilization of services, such as urban or rural residence and household socioeconomic status. The estimation of multilevel logit models was, however, necessitated by the need to control for such unobserved characteristics.

In spite of these limitations, the study contributes to the literature by identifying some of the gaps in the use of maternal health care services by HIV-positive female adolescents in Kenya. To address these gaps, HIV/AIDS programs need to screen their adolescent clients for sexual activity and pregnancy to identify those in need of maternal health services, provide or refer those with such needs for appropriate services and create linkages with maternal and child health clinics to ensure that such clients receive all the relevant services.
