Background: Access to combination antiretroviral therapy (ART) enables HIV-positive women to live longer in good health. Some of these women are sexually active having unintended pregnancies and unsafe abortions because of not using contraceptives. Objective: This study assessed pattern of contraceptive use by HIV-positive women of reproductive age group attending an HIV treatment center at Ladoke Akintola University of Technology Teaching Hospital, Osogbo, Nigeria. Materials and Methods: A descriptive cross-sectional study of 400 HIV-positive women that completed an interviewer-administered semi-structured questionnaire on awareness and use of contraceptives. Data collected were analyzed with SPSS version 17. Results: Majority, 217 (54.3%), had been pregnant since enrollment with 120 (55.3%) having an induced abortion. Majority, 378 (94.5%), were aware of contraception with health workers as the source of awareness being 204 (54%). Although 313 (82.8%) desire to use a contraceptive, 281 (74.3%) currently used a contraceptive with male condom, 130 (34.4%), being the most common type used. Selected factors significantly associated with contraceptive use included age 35 years and above (odds ratio [OR] =2.58, 95% confidence interval [CI] = 1.18–5.63, P = 0.018), higher education (OR = 4.48, 95% CI = 2.80–7.16, P = 0.0001), being unmarried (OR = 4.34, 95% CI = 2.74–6.88, P = 0.0001), skilled worker (OR = 4.64, 95% CI = 2.76–7.81, P = 0.0001), higher income (OR = 2.15, 95% CI = 1.20–3.82, P = 0.01), and increasing duration on highly active ART 6–12 months (OR = 8.88, 95% CI = 4.50–17.50, P = 0.0001) and >12 months (OR = 4.37, 95% CI = 2.27–8.43, P = 0.0001). Conclusions: Some sexually active HIV-positive women were not using contraceptives. It is necessary to increase contraceptive awareness and use among this vulnerable population.

| Introduction|| |
The countries in the resource-limited settings, such as Nigeria, exhibit rapid population growth, high unmet need for family planning, and low contraceptive use.,,,,, The observed high population growth is due to high fertility rate, high birth rate, and steady decline in the high death rate. The rate of population growth in sub-Sahara Africa is one of the highest in the world when compared to the rest of the world.,,
The increasing availability and access to combination highly active antiretroviral therapy (HAART) by people living with HIV/AIDS (PLWHA) has changed HIV/AIDS from a deadly disease to a chronic treatable disease. Good adherence to these lifesaving drugs enables PLWHA to live virtually normal life with their lifespan approaching that of the general population.,, There is a higher HIV prevalence among young women than men worldwide., Previous studies on fertility intention both locally and abroad have reported that PLWHA desire to have children despite the risk of HIV transmission to these children., However, the availability of prevention of mother-to-child transmission (PMTCT) of HIV has reduced markedly the proportion of these children that become HIV positive. The awareness and availability of the PMTCT service to the HIV-positive women have led to higher sexual activity resulting in more unintended pregnancies due to nonavailability or high cost of modern contraceptives.,,,,,, Several studies have reported that these sexually active women without fertility intention usually get pregnant, thereby seeking unsafe abortion from unskilled workers or in unauthorized facilities, especially in countries such as Nigeria where abortion is illegal. These unsafe abortions usually lead to disability or death.,
However, contraceptive use and factors associated with it among the HIV-positive women have not been well understood in Nigeria. This makes the management of the sexual and reproductive health of HIV-positive women to become critical in order to reduce HIV transmission and maternal mortality. Since small family size has been noted as a prerequisite to higher per capital income which makes it essential to provide necessary contraceptives to all women in reproductive age group whether HIV positive or negative,, it is necessary to conduct more study on contraceptive practices of HIV-positive women, hence this study.
This study assessed the pattern of contraceptive use by HIV-positive women of reproductive age group attending an HIV treatment center at Ladoke Akintola University of Technology (LAUTECH) Teaching Hospital, Osogbo, Nigeria.
| Materials and Methods|| |
LAUTECH Teaching Hospital, Osogbo, Osun State, Nigeria, was established in 2001. The hospital provides a spectrum of clinical, surgical, and laboratory services to the general public in Osun State and other neighboring states. It trains medical doctors as well as other health workers at the undergraduate and postgraduate levels.
The HIV treatment center of the hospital, opened to the general public in July 2007, was established by the Institute of Human Virology with the support of the Federal Government of Nigeria. The center provides free comprehensive HIV care to PLWHA in Osun State and other neighboring states. The center opens every Tuesday and Thursday from 8 a.m. to 4 p.m. with emergency care provided daily on a 24-h basis. All women are encouraged to undergo opt-out provider-initiated free HIV counseling and testing with the HIV-positive pregnant women enrolled in the PMTCT program. About 1500 women were on care, 1070 on HAART with 920 in the reproductive age group. Recently, women in the reproductive age group routinely have family planning included in their counseling sessions. Osun State currently has an HIV prevalence rate of 0.9%.
A descriptive cross-sectional study was employed.
These were HIV-positive women in the reproductive age group (15–49 years).
Consenting HIV-positive women in the reproductive age group were included in the study.
HIV-positive women who were pregnant, required emergency care, or were too ill to participate were excluded.
Sample size calculation
The required sample size was calculated using the Leslie Kish formula for estimating single proportions.
n = Z2pq/d2
n = minimum sample size
Z = standard relative deviate at 95% confidence level = 1.96
p = proportion of condom use among HIV-positive women = 50.7% =0.507
q = 1 − p = 1 − 0.507 = 0.493
d = level of precision/margin of error = 5%
Thus, n = 1.962 × 0.507 × 0.493/0.0025 = 384.
However, a sample size of 400 was estimated for the study after nonresponse/attrition was taken into consideration.
Four hundred participants were recruited using systematic sampling method over a 3-month period.
Data collection and analysis
Data were collected using a pretested interviewer-administered questionnaire that included sociodemographic information, awareness and use of contraceptives, and factors associated with contraceptive use. The questionnaire was pretested and face validity was done by the antiretroviral therapy coordinator and authors to ensure that ambiguous questions were either rephrased or removed. The survey questionnaire was written in English, translated to Yoruba for the non-English speaking population, and back-translated to English. The questionnaires were completed in a consulting room designed to ensure patient's privacy. Three medical doctors trained in data collection administered the questionnaire to the participants.
The data were field-edited daily and statistical analysis was done using SPSS version 17 (SPSS Inc., Chicago, IL, USA). Simple descriptive statistics was done to give the sociodemographic characteristics of the study participants. Chi-square test was used to compare categorical variables while multivariate logistic regression model was built to identify significant factors associated with contraceptive use. Independent variables in the model were selected based on whether they were significant at bivariate level and/or whether they have been reported in literature as significant predictors of contraceptive use. The level of statistical significance was set at P < 0.05. Odds ratio (OR) and 95% confidence interval (CI) were obtained to identify factors associated with contraceptive use among the study population.
Ethical approval was obtained from the Ethical and Review Committee of LAUTECH Teaching Hospital. However, written consent was obtained from the respondents before the commencement of questionnaire administration. Data were kept in a passworded computer.
| Results|| |
A total of 400 respondents with completed data were analyzed. Their mean age (standard deviation) was 26.8 (8.2) years ranging 18–47 years with majority, 180 (45%), between 18 and 24 years' age group. Most respondents, 177 (44.2%), were married, 204 (51%) had secondary education, 179 (44.7%) skilled workers, and 240 (60%) Muslims, with 309 (77.3%) earned <$50. Majority, 246 (61.5%), had at least one child presently with 202 (50.5%) being on HAART <6 months [Table 1].
[Table 2] shows the pregnancy occurrence and contraceptive use among participants. Majority, 217 (54.3%), had been pregnant since enrollment into care with 120 (55.3%) having an induced abortion. Majority, 378 (94.5%), were aware of contraceptive methods with 204 (54%) health workers as source of awareness. Although 313 (82.8%) desire a contraceptive, 281 (74.3%) currently use a contraceptive giving a contraceptive prevalent rate of 70.3% (281/400). Contraceptive methods currently used were male condom 130 (34.4%), injectables 66 (23.5%), oral contraceptive pills 39 (13.8%), intrauterine contraceptive devices 10 (3.6%), natural 30 (10.7%), and traditional 6 (2.1%). None of the respondents used female condom. The major reason for using a contraceptive was based on health workers' advice, 164 (52.4%), while partner's objection, 35 (53.8%), was the reason for nonuse of contraceptives.
[Table 3] shows the sociodemographic variables and other variables associated with contraceptive use among respondents. Variables significantly associated with current contraceptive use include increasing age, higher education, being unmarried, skilled worker, earning higher income, increasing duration on HAART, and having at least one child currently (P < 0.05).

[Table 4] reports the logistic regression analysis of selected factors associated with contraceptive use among respondents. These factors significantly associated with contraceptive use included age 35 years and above (OR = 2.58, 95% CI = 1.18–5.63, P = 0.018), higher education (OR = 4.48, 95% CI = 2.80–7.16, P = 0.0001), being unmarried (OR = 4.34, 95% CI = 2.74–6.88, P = 0.0001), skilled worker (OR = 4.64, 95%CI = 2.76–7.81, P = 0.0001), higher income (OR = 2.15, 95% CI = 1.20–3.82, P = 0.01), and increasing duration on HAART 6–12 months (OR = 8.88, 95% CI = 4.50–17.50, P = 0.0001) and >12 months (OR = 4.37, 95% CI = 2.27–8.43, P = 0.0001).

| Discussion|| |
This study assessed the pattern of awareness and use of contraceptives among HIV-positive women. This study reported that despite most participants being aware, some were not using contraceptives. When compared with previous studies, the findings aligned with studies reporting high awareness but low contraceptives use. For instance, Nkwabong et al., 2015, and Laryea et al., 2014, reported that 98% and 74% of their study participants, respectively, were aware of contraceptives with 50.7% and 42.6% using it., It is paramount that all reproductive age women, whatever their HIV status, should be aware of and use modern contraceptives. This reduces the possibility of unintended pregnancies and vertical transmission of HIV to their children.,,
This study reported that over half of the respondents reported induced abortions since enrollment into care. Wanyenze et al., 2015, Warren et al., 2013, and Mersha et al., 2019, reported 40%, 20.7%, and 12.9% had induced abortions among their study population, respectively.,, This emphasized the high unmet contraceptive need among our study population. Furthermore, studies have reported difficulties faced by women seeking abortion care, especially in settings where abortion care is illegal., The need to reduce the likelihood of maternal-to-child transmission of HIV infection makes the awareness and use of contraceptives more important in this vulnerable population. The finding in this study that health workers are the main source of information on contraceptives is similar to findings in previous studies. For instance, Laryea et al., 2014, and Shehu et al., 2016, reported that 74% and 60.2% received contraceptive information from their health-care providers, respectively., This indicates that more training on contraceptives should target health workers to improve the accuracy of information given by them to these clients.
This study reported partner's objection as the major reason the HIV-positive women do not use contraceptives. This information has been reported by previous studies signifying the need to target their partners in contraceptive education.,, Partner notification about the HIV women's contraceptive need will increase contraceptive use if accurate information is given to them. While previous studies have recognized men to be responsible for the large proportion of ill reproductive health suffered by their female partners, their involvement helps not only in accepting a contraceptive but also in its effective use and continuation.,,
None of the women were reported to use female condom while male condom was the most common contraceptive used. This shows that female condom remains unpopular among women as reported in previous studies.,, Since male and female condoms have been shown to be effective in preventing both HIV transmission and unwanted pregnancy with the female condom not really requiring the male cooperation as in using the male condom, it will be good if more awareness and access to female condom is given to these women.
Factors associated with contraceptive use include increasing age, higher education, being unmarried, being a skilled worker, earning higher income, and being on HARRT 6 months and above. Previous studies have reported an unmet need for contraceptives among women who need them., Low income reduces access to contraceptives as the underemployment currently prevalent among young women can make it difficult if not impossible for them to decide about their reproductive and family health needs. Efforts targeted at improving the socioeconomic status of these women will increase contraceptive awareness and use. The study finding that being married does not translate to high contraceptive use among the respondents could partly be explained by their partners' unwillingness to allow the use of contraceptives. The study finding that HIV-positive women on HAART 6 months and above tend to use contraceptives could be explained by the recent inclusion of family planning during PMTCT visits to encourage spacing of birth among the study population.
Limitation of the study
This study is limited by its cross-sectional design as no cause–effect relationship could be established. Furthermore, some respondents could have given socially acceptable responses to some questions differing from their actual behavior despite every effort made to explain the study purpose. Furthermore, their partners' contraceptive behavior could not be assessed since they were not interviewed.
| Conclusions|| |
Unintended pregnancy and inadequate contraceptive use were reported among HIV-positive women. It is necessary to increase contraceptive awareness and use among this vulnerable population. Further contraceptive education targeting health workers and the male partners of these women will increase contraceptive use, especially the female condom if made available at an affordable cost to the respondents. The current practice of discussing family planning during counseling sessions and PMTCT visits should be evolved into integrating family planning and HIV care.
