"They call me the 'Great Queen'": implementing the Malkia Klabu program to improve access to HIV self-testing and contraception for adolescent girls and young women in Tanzania. Reprod Health 2024; 21:21. [PMID: 38321482 PMCID: PMC10848389 DOI: 10.1186/s12978-024-01744-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 01/23/2024] [Indexed: 02/08/2024] Open
Abstract
BACKGROUND Adolescent girls and young woman (AGYW) comprise a significant proportion of new HIV infections and unintended pregnancies in sub-Saharan Africa yet face many barriers to accessing family planning and reproductive health (FPRH) information and services. Developed via human-centered design, the Malkia Klabu ("Queen Club") program aimed to facilitate access to HIV self-testing (HIVST) and FPRH information and products at privately-owned drug shops. We sought to understand barriers and facilitators to program implementation in a 4-month pilot in Tanzania. METHODS Forty semi-structured interviews were conducted with participants in a cluster randomized trial of the Malkia Klabu program from November 2019 through March 2020, including 11 with AGYW, 26 with drug shopkeepers, and three with counselors at health facilities to whom AGYW were referred. Interviews were audio-recorded, transcribed, coded, and analyzed to identify key themes. The Consolidated Framework for Implementation Research (CFIR) was used to assess barriers and facilitators to program implementation at multiple levels. CFIR considers the outer setting (e.g., culture and systemic conditions), the inner setting where the intervention is implemented (e.g., incentives, relationships, and available resources), the individuals involved, the innovation as it relates to stakeholder needs, and the implementation process. RESULTS The Malkia Klabu program reshaped and directed the role of drug shopkeepers as providers of information and resources rather than FPRH gatekeepers. Key implementation facilitators included the program's adaptability to a wide range of needs and stages of readiness among AGYW, ability to capitalize on AGYW social networks for driving membership, responsiveness to AGYW's need for privacy, and positive contributions to the income and community standing of drug shopkeepers. Components such as HIVST were highly acceptable to both AGYW and shopkeepers, and the introduction of the loyalty program and HIVST kits in shops opened doors to the provision of FPRH products and information, which was further facilitated by program tools such as videos, product displays, and symbol cards. Although some shopkeepers maintained beliefs that certain contraceptive methods were inappropriate for AGYW, most appeared to provide the products as part of the program. CONCLUSIONS The Malkia Klabu intervention's success was due in part to its ability to address key motivations of both AGYW and drug shopkeepers, such as maintaining privacy and increasing access to FPRH products for AGYW and increasing business for shops. Better understanding these implementation barriers and facilitators can inform the program's future adaptation and scale-up. TRIAL REGISTRATION clinicaltrials.gov #NCT04045912.

Impact of a post-partum family planning intervention on contraception and fertility in Tanzania: two-year follow-up of a cluster-randomised controlled trial. EUR J CONTRACEP REPR 2024; 29:24-31. [PMID: 38230668 DOI: 10.1080/13625187.2023.2290985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 11/29/2023] [Indexed: 01/18/2024]
Abstract
PURPOSE We evaluate contraceptive use and pregnancy two years following an intervention in Tanzania, which provided antenatal post-partum family planning counselling and post-partum intrauterine device (PPIUD) services following delivery. METHODS We analyse data from five hospitals in Tanzania using a difference-in-difference cluster randomised design, with randomisation at the hospital level. We use women-level data collected at the index birth and a follow-up survey two years later among 6,410 women. Outcomes (overall modern contraceptive use, contraceptive type, pregnancy) are modelled with an intent-to-treat (ITT) approach using linear regression. We compare with the complier average causal effect (CACE) of the intervention among those counselled. RESULTS The intervention increased long-term PPIUD use by 5.8 percentage points (95% CI: 0.7-11.2%) through substitution away from other modern methods. There was no impact on overall modern contraceptive prevalence or pregnancy. Only 29% of women reported receiving PPIUD counselling. When accounting for this in the CACE analysis we saw a larger impact with 25.7% percentage point increase in PPIUD use (95% CI: 22.7-28.6%). CONCLUSION The intervention provided women an additional contraceptive choice, resulting in higher use of PPIUD over two years. Increase in PPIUD use was brought about by shifting methods, not creating new modern contraceptive users.

Abeid RA, Sumari EI, Qin C, Lyimo AA, Luttaay GA. Uptake of modern contraceptive methods among women of reproductive age in Chake District-Pemba Tanzania: a descriptive crossectional study. Contracept Reprod Med 2023; 8:35. [PMID: 37461065 PMCID: PMC10351188 DOI: 10.1186/s40834-023-00234-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 06/21/2023] [Indexed: 07/20/2023] Open
Abstract
BACKGROUND The uptake of the modern contraceptive method provides chances for women and couples to reach optimal child spacing, achieve the desired family size and prevent unsafe abortions and maternal deaths. Despite the efforts in the health sector still, the contraceptive prevalence rate in Zanzibar remains low (9.1%). In Pemba, few studies have been done on modern contraceptive uptake and little is known about factors that hinder the uptake of modern contraceptives among women of reproductive age. This study investigated the uptake of modern contraceptive methods among women of reproductive age (18-45 years) and its associated factors. METHODS This was a quantitative cross-sectional study conducted in Chake District Hospital, Pemba Tanzania. A stratified random sampling technique was used to recruit 214 eligible participants for the study. After we informed the participants, data were collected using a structured English questionnaire. The collected data was analyzed using SPSS version 25, descriptive analysis was done to determine frequencies. A chi-square test was done to determine the association between the study variables and multivariate logistic regression to check the nature and strength of the association. The p<0.05 was considered statistically significant. RESULTS This study included 214 women of with majority 79(36.9%) at the age group of 21-30 years, 100(46.7%) had secondary education and 187(87.4%) married. Most of the participants 212(99.1%) have heard about modern contraceptives, with health facilities being the common source of information191(45.3). More than half 120(56.1%) of the participants were not using any modern contraceptive method and injectable 38(40.4%) was the commonly reported method among users. Among the users of modern contraceptives, lack of power to decide 180(84.1%), fear of divorce 141(65.9%), and social perception of users as the cause of reduced workforce in the future 161(75.2%) were common barriers. Participants provided suggestions to improve modern contraceptive uptake including male involvement 203(94.9%) and community awareness 182(85%). Further analysis revealed women with college/university education were 2 times more likely to use modern contraceptives method compared to those with primary or not attended school(p=0.023, OR=2.437, 95% CI: 1.129-5.259). Moreover employed women were 2 times more likely to use modern contraceptives compared to unemployed/housewives (p=0.028, OR=1.844, CI=1.068-3.185). CONCLUSION This study assesses the uptake of modern contraceptives among women of reproductive age. Results showed a low uptake of modern contraceptives in this population. Although the observation in this study is similar to those reported in other countries, the updated information is still important to the policymakers and the Ministry of Health in the studied district.

Findings from a cross-sectional study in Nigeria. BMC Health Serv Res 2023; 23:24. [PMID: 36627614 PMCID: PMC9832820 DOI: 10.1186/s12913-023-09032-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Accepted: 01/04/2023] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Studies in many developing countries have shown that community health workers (CHWs) are valuable for boosting contraceptive knowledge and usage. However, in spite of the evidence, studies in Nigeria have rarely examined whether in the absence of skilled health personnel such as doctors and nurses in rural and remote communities, the health service contacts of non-users with CHWs drive the intention to use modern contraceptives. This study, therefore, examines the extent to which health service contacts with CHWs are associated with the intention to use modern contraceptives among non-users in rural communities of Nigeria. METHODS This study adopted a descriptive cross-sectional design. Data were extracted from the most recent Nigeria Demographic and Health Survey (NDHS). The study analyzed a weighted sample of 12,140 rural women. The outcome variable was the intention to use modern contraceptives. The main explanatory variable was health service contacts with CHWs. Statistical analyses were performed at three levels with the aid of Stata version 14. Three multivariable regression models were estimated using an adjusted Odds Ratio (aOR) with a 95% confidence interval. Statistical significance was set at p < 0.05. RESULTS Findings showed that more than a quarter (29.0%) of women intends to use modern contraceptives. Less than one-fifth (15.9%) of the women had health service contacts with CHWs. In Model 1, women who had health service contacts with CHWs were more likely to intend to use modern contraceptives (aOR =1.430, 95% CI: 1.212-1.687). Likewise, in Model 2, women who had health service contacts with CHWs had a higher likelihood of intending to use modern contraceptives (aOR = 1.358, 95% CI: 1.153-1.599). In Model 3, the odds of intention to use modern contraceptives were higher among women who had health service contacts with CHWs (aOR =1.454, 95% CI: 1.240-1.706). CONCLUSION In rural areas of Nigeria, health service contacts with CHWs are significantly associated with the intention to use modern contraceptives. Family planning programmers should leverage the patronage of CHWs for the purpose of family planning demand generation in rural areas.

PLOS GLOBAL PUBLIC HEALTH 2022; 2:e0000208. [PMID: 36962492 PMCID: PMC10022240 DOI: 10.1371/journal.pgph.0000208] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Accepted: 01/23/2022] [Indexed: 06/18/2023]
Abstract
Adolescent sexual and reproductive health (ASRH) in East Africa has prioritized research on the barriers to care, communication, and ASRH knowledge, attitudes, and practices. However, there is little research examining the extent to which meaningful adolescent engagement in research is achieved in practice and how this influences the evidence available to inform ASRH services. This review offers a critical step towards understanding current approaches to adolescent engagement in ASRH research and identifying opportunities to build a strengthened evidence base with adolescent voices at the centre. This scoping review is based on Arksey and O'Malley's (2005) framework, employing a keyword search of four databases via OVID: Medline, Global Health, Embase and PsycINFO. Two reviewers screened title, abstract and full text to select articles examining ASRH in Tanzania, Rwanda, Kenya, and Uganda, published between 2000 and 2020. After articles were selected, data was extracted, synthesized, and thematically organized to highlight emerging themes and potential opportunities for further research. The search yielded 1201 results, 34 of which were included in the final review. Results highlight the methods used to gather adolescent perspectives of ASRH (qualitative), the content of those perspectives (knowledge, sources of information, gaps in information and adolescent friendly services), and the overall narratives that frame discussions of ASRH (risky sexual behaviour, stigma, and gender norms). Findings indicate the extent of adolescent engagement in ASRH research is limited, resulting in a lack of comprehensive evidence, consistent challenges with stigma, little information on holistic concepts and a narrow framing of ASRH. In conclusion, there is opportunity for more meaningful engagement of adolescents in ASRH research. This engagement can be achieved by involving adolescents more comprehensively throughout the research cycle and by expanding the range of ASRH topics explored, as identified by adolescents.

SAGE Open Med 2021; 9:20503121211021256. [PMID: 34158936 PMCID: PMC8182170 DOI: 10.1177/20503121211021256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 05/04/2021] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVES This study aimed to determine postpartum modern contraceptive use among first-time young mothers attending child welfare clinics in the Eastern Region of Ghana and explore factors that influence family planning uptake after the first delivery, including fear of infertility. METHODS This facility-based, cross-sectional study used interviewer-administered structured questionnaires. The study recruited 422 first-time young mothers aged 15-24 years, with 6- to 18-month-old babies attending child welfare clinics. RESULTS Overall, less than half (44%) of first-time mothers used modern contraceptives within 18 months after delivery. Fear of infertility after contraceptive use (56%) is the main barrier reported as the reason for women's non-use of modern contraceptives. Mothers with tertiary education have higher odds of using postpartum contraceptives (adjusted odds ratio =1.6, 95% confidence interval: 0.4-2.0). Compared to mothers with younger children, those with children older than 6 months have higher odds of postpartum contraceptive use (adjusted odds ratio = 1.3, 95% confidence interval: 0.3-1.7). Nonspousal communication (adjusted odds ratio = 0.1, 95% confidence interval: 0.1-0.3) as compared to communication among partners about contraception and those in formal employment (adjusted odds ratio = 0.3, 95% confidence interval: 0.1-0.7), were less likely to use postpartum contraceptives. CONCLUSION Considering that there is low postpartum contraceptive utilization, mostly due to concerns about fear of infertility after use, it is paramount to intensify education on actual side effects and reformulate policies that address specific concerns of infertility among mothers and contraceptive use.

Abstract
BACKGROUND High rates of unintended adolescent pregnancy are a significant health problem in Uganda. To improve access to family planning (FP) services, community-based Village Health Teams (VHTs) are widely employed in Uganda to deliver education and services. However, evaluations of FP programs suggest that mainly older, married women use VHT FP services. METHODS To better understand youth reluctance to use VHTs, we collected quantitative FP and contraceptive-seeking behavior data from a survey of 250 youths aged 15-25 in randomly selected households in Nakaseke District, which we triangulated with data from 3 focus group discussions (FGDs) (n = 15). RESULTS Most respondents received FP services from the formal health sector, not VHTs. Only half had talked to a VHT, but 65% knew that VHTs provide free FP services, and most (82%) felt comfortable talking to VHTs about FP. The main reasons for discomfort were fear that VHTs would violate privacy (mentioned by 60% of those not comfortable), that VHTs would talk to parents (33%), shyness (mentioned by 42% of those ≤18), and fear of being judged (14%). Concern about side effects was the most common reason for not using FP methods. Survey respondents said having VHTs of the same sex was important, particularly those in the youngest age group (OR = 4.45; 95%CI: 1.24, 16.00) and those who were unmarried (OR = 5.02; 95%CI: 2.42, 10.39). However, FGD participants (who were older than survey respondents on average) often preferred older VHTs of the opposite sex, whom they viewed as more professional and trustworthy. Respondents said the primary deciding factors for using VHTs were whether privacy would be respected, the proximity of care, and the respectfulness of care. CONCLUSIONS VHTs are a known source of FP services but not widely used by youth due to privacy and quality of care concerns. VHT messaging and training should increase focus on ensuring privacy, protecting confidentiality, providing respectful care, and addressing concerns about contraceptive side effects. Preferences for VHTs of similar age and sex may be more important for younger adolescents than older youths for whom quality concerns predominate.

Abstract
Purpose Addressing the contraceptive needs of young married women is critical to improve their health and well-being. In patriarchal societies, young married women are under intense pressure to demonstrate their fecundity. Therefore, research that specifically address the needs for contraception of young married women have been generally given less emphasis in Ethiopia. This study assessed the extent of unmet needs for contraception and its associated factors among young married women in Eastern Ethiopia. Methods A community-based cross-sectional study was conducted among young married women (14–24 years of age) in Eastern Ethiopia. Data were collected using a structured questionnaire. The prevalence ratio (PR) with 95% confidence intervals (CIs) was calculated, and factors associated with unmet needs for contraception were identified using log-binomial regression statistical model. Results Among 2933 young women interviewed, the unmet need for contraception was 1014 (34.6%; 95% CI, 32.9%–36.4%). The prevalence of unmet needs for contraception decreased with increased young women’s household decision-making autonomy score (APR= 0. 76; CI=0.62–0.94). Exposure to family planning (FP) information during the last 12 months (APR= 1.24; CI=1.1–1.42), age 18 or more years (APR=1.25; CI=1.04–1.5), multiparty (APR= 1. 9; CI=1.7–2.1) and desire to have 5 children or lesser than 5 children (APR= 1. 2; CI=1.06–1.32) were associated with higher prevalence of unmet needs for contraception. Conclusion One-third of married young women had unmet needs for contraception. More efforts to empower women to make decisions that affect their own life and providing appropriate family planning information are necessary to reduce the burden of unmet needs among young married women in rural settings in Ethiopia.
