    Thesis (Ph.D.)-University of Natal, 2003.Despite its widespread use, little research has been undertaken on the use of progestogen-only injectable contraceptives by South African women. This thesis is comprised of two sections. Section 1 provides the first comprehensive description of injectable contraceptive use among rural South African women. It includes an analysis of the contraceptive method mix, prevalence of injectable contraceptive use, discontinuation patterns and reported side effects. A comparison of depot medroxyprogesterone acetate (DMPA) versus norethisterone oenanthate (NET-EN) focuses on utilization patterns and costs. The second section gives an account of the pharmacokinetics of DMPA including the first ever population analysis. A cross-sectional, community-based household survey was undertaken in the Hlabisa sub-district of KwaZulu-Natal, South Africa. Interviews were held during 1998 and 1999, with 848 randomly selected women (aged 15-49 years) and with 14 focus groups. There was a heavy reliance on injectable contraceptives which were used by 74% of women practising contraception. By contrast, the condom was the current method of only 4%. The injectable method was the most commonly used method among teenagers. However, in most cases, contraceptive use appeared to commence only after the first pregnancy. Slightly more NET-EN (54%) than DMPA (46%) was used, with younger women more likely to use NET-EN than DMPA (p=0.001). No significant differences in self-reported side effects were found between current users of the two injectables. Health workers played an important role in women's decisions to use the injectable, and in product selection, with NET-EN being recommended for younger women on the basis of concerns about method reversibility. While some women used injectables for long periods of time, discontinuation rates at two years were high, most commonly due to menstrual disturbances. Many side effects were reported by users of both DMPA and NET-EN, with amenorrhoea the most common, experienced by 63% of current injectable users. Heavy bleeding was most commonly reported by previous users (38%). Vaginal wetness was also common, mentioned by 18% and 29% of current and previous users respectively. Utilisation patterns of the two injectable products (DMPA and NET-EN) were analysed by means of a Pareto analysis of injectables issued from four South African provincial pharmaceutical depots over three financial years (1997/8, 1998/9 and 1999/2000). Injectables accounted for a substantial share of total state expenditure on drugs. While more DMPA than NET-EN was issued, NET-EN distribution from two depots increased over the period of analysis, even though DMPA was the cheaper option. The pharmacokinetic analysis was undertaken amongst DMPA users routinely attending family planning services in three Durban clinics in 1996. Medroxyprogesterone acetate levels at the end of the dosing interval were analysed for 94 women. In addition a population pharmacokinetic analysis of 291 serum levels from 111 DMPA users was undertaken. This involved the use of Non Linear Mixed Effect Modelling (NONMEM) to fit the data and determine the pharmacokinetic parameters, apparent clearance (CLIP) and apparent volume of distribution (VIP), and to estimate the influence of covariates on CLIP and VIP (where P is the bioavailability). The final model estimates for CLIP and VIP were 1080 (95% confidence interval: 994, 1166) litres/day and 86200 litres (95% confidence interval: 68246, 104154) respectively. No significant relationships were found between the covariates tested and CLIP and VIP. Concerns raised in the literature about the influence of weight or ethnicity on the pharmacokinetics of DMPA were shown to be unfounded. In the context of South Africa's HIV epidemic, the heavy reliance on injectable contraceptives, which offer no protection against HIV, should be addressed by expanding the contraceptive method mix to include barrier methods such as the female condom. Health providers are influential in contraceptive decision-making and should be encouraged and supported to redress the dependence on the injectable method alone, taking into account the need of many for dual protection against HIV and unwanted pregnancy. Provider counseling should also focus on adherence to dosing regimens, improving continuation rates, and should provide appropriate advice for women complaining about vaginal wetness with injectable use. Promotion of one injectable product over another to younger women is not appropriate. Since DMPA is the cheaper product, provider training about the rational use of injectable contraceptives should include cost considerations

    OBJECTIVE: To determine the prevalence and co-factors associated with the practice of dual protection against sexually transmitted infections (STIs) and unwanted pregnancy in a cross-sectional sample of South African women. DESIGN: Secondary analysis of cross-sectional household survey data. METHODS: Statistical analysis of responses by sexually active women to the question, 'Was a condom used on the last occasion you had sex?' were obtained from the women's questionnaire of the South African Demographic and Health Survey in relation to a number of other variables. RESULTS: (i) 10.5% of all sexually active women aged 15-49 years used a condom at last sex and 6.3% used a condom as well as another contraceptive method; (ii) condom use is more likely among younger, more educated, more affluent, and urban women, and among women who change partners more frequently; (iii) reasons for not using condoms are more likely to be associated with the personal attitudes of women or their partners than with poor knowledge of or lack of access to condoms; (iv) women who have no need or desire to prevent pregnancy are less likely to use condoms; and (v) there is a minority of sexually active women, characterised by social disadvantage, who have difficulty obtaining condoms. CONCLUSIONS: There is an urgent need for targeted programmes that increase dual protection with condoms

    Women’s contraceptive choice following the use of Implanon NXT: Findings from a study in Durban, South Africa

    Implanon NXT was introduced in South Africa (SA) in 2014 to expand the contraceptive method mix. While studies have explored patterns of implant use, data on contraceptive choice following implant removal is limited. Here, we describe contraceptive choice among 120 women requesting Implanon NXT removal, between 2017 and 2018, at an urban reproductive health clinic in Durban, SA. Among women who used the implant for three years (n=91), >50% chose to reinsert Implanon NXT. Reasons for choosing to reinsert included satisfaction with the implant, the desire for a long-acting method and having had no side effects. A third of women chose not to reinsert Implanon NXT after three years due to side effects such as problematic bleeding. Most women requesting early removal of the implant switched to male condoms, injectables or oral contraceptives. Contraceptive services should provide women with contraceptive options and allow women to make informed decisions regarding contraceptive choice, in addition to providing support and managing side effects among Implanon NXT users. Implanon NXT a été introduit en Afrique du Sud (SA) en 2014 pour élargir la gamme de méthodes contraceptives. Alors que les études ont exploré les modèles d'utilisation des implants, les données sur le choix de la contraception après le retrait de l'implant sont limitées. Ici, nous décrivons le choix de la contraception parmi 120 femmes demandant le retrait d'Implanon NXT, entre 2017 et 2018, dans une clinique de santé reproductive urbaine à Durban, SA. Parmi les femmes ayant utilisé l'implant pendant trois ans (n = 91),> 50% ont choisi de réinsérer Implanon NXT. Les raisons du choix de la réinsertion comprenaient la satisfaction à l'égard de l'implant, le désir d'une méthode à action prolongée et l'absence d'effets secondaires. Un tiers des femmes ont choisi de ne pas réinsérer Implanon NXT après trois ans en raison d'effets secondaires tels que des saignements problématiques. La plupart des femmes demandant le retrait précoce de l'implant sont passées aux préservatifs masculins, aux injectables ou aux contraceptifs oraux. Les services de contraception devraient offrir aux femmes des options contraceptives et leur permettre de prendre des décisions éclairées concernant le choix de la contraception, en plus de fournir un soutien et de gérer les effets secondaires parmi les utilisatrices d'Implanon NXT

    Reproductive Counseling by Clinic Healthcare Workers in Durban, South Africa: Perspectives from HIV-Infected Men and Women Reporting Serodiscordant Partners

    Understanding HIV-infected patient experiences and perceptions of reproductive counseling in the health care context is critical to inform design of effective pharmaco-behavioral interventions that minimize periconception HIV risk and support HIV-affected couples to realize their fertility goals. Methods. We conducted semistructured, in-depth interviews with 30 HIV-infected women (with pregnancy in prior year) and 20 HIV-infected men, all reporting serodiscordant partners and accessing care in Durban, South Africa. We investigated patient-reported experiences with safer conception counseling from health care workers (HCWs). Interview transcripts were reviewed and coded using content analysis for conceptual categories and emergent themes. Results. The study findings indicate that HIV-infected patients recognize HCWs as a resource for periconception-related information and are receptive to speaking to a HCW prior to becoming pregnant, but seldom seek or receive conception advice in the clinic setting. HIV nondisclosure and unplanned pregnancy are important intervening factors. When advice is shared, patients reported receiving a range of information. Male participants showed particular interest in accessing safer conception information. Conclusions. HIV-infected men and women with serodiscordant partners are receptive to the idea of safer conception counseling. HCWs need to be supported to routinely initiate accurate safer conception counseling with HIV-infected patients of reproductive age

    Participatory approaches involving community and healthcare providers in family planning/contraceptive information and service provision: a scoping review.

    As efforts to address unmet need for family planning and contraception (FP/C) accelerate, voluntary use, informed choice and quality must remain at the fore. Active involvement of affected populations has been recognized as one of the key principles in ensuring human rights in the provision of FP/C and in improving quality of care. However, community participation continues to be inadequately addressed in large-scale FP/C programmes. Community and healthcare providers’ unequal relationship can be a barrier to successful participation. This scoping review identifies participatory approaches involving both community and healthcare providers for FP/C services and analyzes relevant evidence. The detailed analysis of 25 articles provided information on 28 specific programmes and identified three types of approaches for community and healthcare provider participation in FP/C programmes. The three approaches were: (i) establishment of new groups either health committees to link the health service providers and users or implementation teams to conduct specific activities to improve or extend available health services, (ii) identification of and collaboration with existing community structures to optimise use of health services and (iii) operationalization of tools to facilitate community and healthcare provider collaboration for quality improvement. Integration of community and healthcare provider participation in FP/C provision were conducted through FP/C-only programmes, FP/C-focused programmes and/or as part of a health service package. The rationales behind the interventions varied and may be multiple. Examples include researcher-, NGO- or health service-initiated programmes with clear objectives of improving FP/C service provision or increasing demand for services; facilitating the involvement of community members or service users and, in some cases, may combine socio-economic development and increasing self-reliance or control over sexual and reproductive health. Although a number of studies reported increase in FP/C knowledge and uptake, the lack of robust monitoring and evaluation mechanisms and quantitative and comparable data resulted in difficulties in generating clear recommendations. It is imperative that programmes are systematically designed, evaluated and reported
