Abstract

Background

Studies from different contexts worldwide indicate that HIV positive patients manifest high-risk sexual behavior characterized by fertility intentions, multiple sexual partners, non-use of contraceptives and non-disclosure of HIV status to their sex partners. The objective was to analyze fertility desires among persons living with HIV at a treatment centre in Kabale Hospital, Southwestern Uganda.

Methods

From January to August 2009, we interviewed 400 HIV positive patients seeking care using an interviewer-administered questionnaire. We assessed socio-demographic variables, reproductive history, sexuality and fertility desires. At bivariate and multivariate analysis, characteristics of participants who reported or did not report desire to have a child in the near future were compared.

Results

Of the 400 respondents, (25.3%) were male, 47.3% were aged 25-34 years, over 85% were currently married or had ever been married, and the 62% had primary level of education or less. Over 17% had produced a child since the HIV diagnosis was made, and 28.6% reported that they would like to have a child in the near future. Age of the respondent, being single (versus being ever-married) and whether any of the respondents' children had died were inversely associated with fertility intentions.

Conclusion

Factors inversely associated with fertility intentions were age of the respondent, marital status and whether any of the respondents' children had died. Use of antiretroviral therapy was not associated with fertility intentions.

Introduction

The majority of new human immunodeficiency virus (HIV) infections that occur in children worldwide occur among children born to HIV positive mothers, who acquire the HIV infection from their mothers [1]. Through HIV treatment and support centres, HIV-infected persons and their partners are provided with the required information about the HIV prevention and treatment strategies available [2]. Despite counseling, studies from different contexts worldwide in both developed countries [37]and developing countries [8, 9]in the era of wide access to antiretroviral drugs [1013]indicate that many HIV positive individuals continue to exhibit high risk sexual behavior characterized by fertility intentions. Studies from Uganda indicate that 3-20% of married or cohabitating couples are HIV sero-discordant [1416]. Within a given socio-cultural context, measuring fertility intentions among HIV-positive individuals (who were advised against having children) is a good indicator of the reproductive choices made by HIV positive individuals. The objective was to analyze fertility intentions among persons living with HIV/AIDS at a treatment and counseling centre in Kabale Hospital, Southwestern Uganda, and specifically, analyze whether being on antiretroviral therapy was associated with fertility intentions.

Methods

Study setting

Kabale District is a rural highland district in southwestern Uganda, about 560 km from the capital city, Kampala. The 2002 national census estimated the population of Kabale District at about 471,800, with an annual population growth rate of 3%. This district is densely populated- with an area of 1,827 square kilometers, the population density in the district in 2009 is estimated at 318 people per km². Kabale Hospital is a public regional referral hospital funded by the Uganda Ministry of Health and general care in the hospital is free.

Study design

The study design was a cross-sectional study conducted at Kabale hospital HIV treatment and counseling centre, from January to August 2009. The study inclusion criteria were having attended for at least three months, availability of HIV sero-status results, HIV positive diagnosis and willingness to consent for participation in the study. During the eight-month study period, 400 HIV positive individuals were recruited into the study

Data collection procedure

Participants were screened and recruited by research assistants who were health workers attached to the HIV treatment, care and support centre. Using an interviewer-administered questionnaire and through records review of information in the client database, data was collected on socio-demographic variables such as age, education level, marital status, number of years in marriage, employment status, and social habits (drinking alcohol or smoking). Reproductive history: parity and number of living children(number of biological children of the respondent who were alive), sexuality (number of sexual partners, change of sexual partners, frequency of sexual intercourse and condom use) were also assessed. For fertility intention, individuals' subjective feelings regarding future conception (whether the respondent wanted to have a child in the next two years) was assessed.

Data analysis

Data was analyzed using the STATA software (Release 9) to provide frequencies and percentages for categorical variables and means and standard deviations for numerical variables. At bivariate analysis, characteristics of the participants who reported fertility intentions were compared with those who did not, using Pearson's chi-square test for categorical data and Student t-test for numerical data. To adjust for confounding, collinearity and interaction and thereby analyze factors that were independently associated with fertility intention, multivariate logistic-regression analysis was conducted. During the stepwise modeling for regression analyses, all variables of clinical importance or with p-value 0.2 and less on bivariate analysis were considered for inclusion. Intention to have a child in the near future (fertility intention) was entered as intends = 1, does not intend = 0. Ever treatment for sexually transmitted infection since the HIV diagnosis was entered as Ever treated = 1, Never treated = 0. Consistent contraceptive use was entered as present = 1, absent = 0. Parity, number of living children and age of spouse, age of sexual debut and age at marriage were entered as numerical variables. Other categorical variables were entered as present or yes = 1, and absent or No = 0. Participant age was evaluated as a numerical variable and as 5-year age categories. The model goodness-of-fit of the final logistic regression models was assessed by Pearson's chi-square test.

Ethical considerations

Ethical approval was obtained from Kabale Regional Hospital. Counseling about sexuality, condom use, dual protection and fertility was provided to all the participants, and all eligible participants were provided with antiretroviral therapy.

Results

Of the 400 respondents (Table 1), 101 (25.3%) were male, 47.3% were in the age category 25-34 years, over 85% were currently married or had ever been married, and 62% had primary level of education or less. The mean age of sexual debut, age at marriage and age when participants had their first child was 18.3 years, 20.5 years and 21.8 years respectively. Only 191 (53.1%) described their intimate relationships as stable.

Table 2 shows the reproductive history of the respondents stratified by gender. Of the 400 respondents, 63 (17.6%) had produced a child since the HIV diagnosis was made, and 108 (28.6%) reported that they intended to have a child in the near future (within next two years). Fifty four respondents (13.4%) were unaware that if they were HIV positive, they could pass on the virus to the unborn baby. Only 214 (53.1%) reported that they were aware that their regular sexual partner/partners knew their HIV sero-status, despite 330 respondents (82.5%) already taking antiretroviral drugs. Of the 197 (49.3%) who were aware of the partners' HIV sero-status, 170 (86.7%) knew the partners were HIV positive. More than 10% had had sexual intercourse with more than one sexual partner in the previous 6 months.

In table 3, having produced a child since the HIV diagnosis, being single (versus being married, separated or divorced), the number of living children, whether the respondent perceived the relationship as stable and having had sex in the previous six months were significantly associated with fertility intention (though respondents reported less likelihood of desiring to have children in the next two years) (p-value less than 0.05). On the other hand, the number of sexual partners in the previous six moths was significantly associated with fertility intention (those with more sexual partners were more likely to have fertility intention (p-value less than 0.05)). Being on ARVs was not significantly associated with fertility intentions. In table 4, being on antiretroviral therapy was not significantly associated with fertility intentions. The factors independently associated with desiring a child in the near future among HIV positive persons were age of the respondent, marital status and when any of the respondents' children had died. Young age, those who were single (as compared to the ever-married) and respondents whose children had died were significantly less likely to have fertility intentions.

Discussion

Since access to antiretroviral therapy has improved quality of life and survival for HIV infected people, many will contemplate child bearing. Identification of contextual determinants of decision to have children among HIV positive couples is useful for designing of policies and establishing intervention priorities in reproductive health for this population. Being on antiretroviral therapy was not associated with fertility intention in this population. Respondents who were of young age, were single or had lost a child were unlikely to have fertility intentions.

Several studies that have described pregnancy intention rates in different contexts of people living with HIV have reported rates that range from 17% in Uganda [10] to 63% in Nigeria [17]. Studies from Zambia [18] and Zimbabwe [19] found no effect of HIV diagnosis on subsequent childbearing, implying that pregnancy intentions were unaffected by HIV diagnosis. Fertility intentions among HIV positive persons are more common in developing countries (where the overall fertility in the population is still high, contraceptive use is low, and unmet need for contraception is high). They have also been noted in more developed countries such as Brazil, United States of America, France and Italy [2026].

The finding of lack of association of fertility intention and antiretroviral therapy contrasts that of Maier et al [13] in the same socio-cultural context who had found that antiretroviral therapy had increased fertility desires (but had little influence on pregnancy rates and live birth rates of HIV positive individuals). At the time when the HIV pandemic in the developing countries matures, the majority of affected individuals are in the reproductive age, where they may desire to have children in spite of their HIV status [10, 15, 27]. Factors influencing HIV positive people's pregnancy decisions, especially partner's desire to have a child and young age do not differ from those of influencing HIV non-infected women [28].

The study findings are consistent with previous research which showed that many cohabiting couples do not mutually know their HIV status [10, 13, 29]. HIV prevention programs to protect the negative partners in discordant couples in Uganda face the dilemma of non-disclosure of HIV status for HIV positive individuals [14, 16], many of whom are already taking antiretroviral drugs. Some of the contextual factors that influence sexuality, fertility intentions, reproductive decision making and subsequent sexual behavior of HIV positive individuals are personal and partners' desire to have children, societal reproductive expectations and non-disclosure of HIV sero-status in sexual relationships [14, 16, 29]. These contextual factors, which seem not to have changed for HIV positive individuals in the era of access to antiretroviral therapy, might be partly responsible for the high unmet need for contraception [10, 30, 31].

Conclusion

Factors that influence fertility intention among HIV positive persons were age of the respondent, marital status and whether any of the respondents' children had died. Respondents who were of young age, were single or had lost some children were unlikely to desire a child in the near future. Being n antiretroviral therapy was not associated with desire to have a child in the near future. The finding that counseling and support given from an HIV care and treatment center did not alter HIV positive individuals' perceptions and subsequent sexual behavior has implication for counseling these clients.
