BACKGROUND: Injectable contraceptives are fast becoming the method of choice among women in sub-Saharan Africa (SSA). Specifically, the subcutaneously administered depot–medroxyprogesterone acetate (DMPA-SC) is gaining traction as a convenient, private and effective method to address unmet need for family planning (FP). The objective of this study was to determine the trend in DMPA-SC use in Nigeria. METHODS: Data was extracted from the National Health Management Information System (NHMIS) FP register on DMPA-SC uptake in public health facilities and through community-oriented resource providers (CORPS) in 10 Nigerian states. The linear trend model was adopted in data analysis based on lowest measure of dispersion and/or highest adjusted coefficient of determination (R(2)). The statistical significance was determined at 5%. RESULTS: There was an upward trend in the use of DMPA-SC among clients who received the service through health providers, CORPS and self-injection in the 10 project states over a period of 12 months (August 2019–July 2020). In addition, the linear trend model showed that for every unit increase in months, the average number of women expected to use DMPA-SC through health providers, CORPS and self-injection will increase by 1308.3 (Yt = 3799.7 +1308.3*t), 756.73 (Yt = −1030.8 +756.73*t) and 77.864 (Yt = −159.7 +77.864*t) respectively. In all models, the adjusted coefficient of determination was 99.9% which showed good model fitness. The results also showed that the number of DMPA-SC clients varied across the project states with Niger (32,988) and Oyo (31,511) states reporting the highest number of clients over the period of 12 months. CONCLUSION: There was an increasing use of DMPA-SC and self–injection among clients over time. Health facility and community-based FP programs should be strengthened to ensure improved access to FP services.

Family planning (FP) has age-long benefits in maternal and infant mortality reduction. 1 In resource-poor settings, 214 million women of childbearing age had an unmet need for FP. 2 Though the FP2020 global partnership set an ambitious goal to reach more than half of these women with voluntary FP, 3 yet achieving this goal was practically impossible. Many factors have continued to hamper contraceptive use, such as: experiences of side effects, cost, method dissatisfaction, convenience, limited method options and intimate partner disapproval. 4, 5 In addition, home, community and health institutions structure have placed limits on women's ability to take fertility control decision. For example, cultural, normative, societal and financial concerns as well as the requirement for partner's permission to access services, religious leaders' subtle and overt pushes to employ traditional FP methods, and out-ofpocket costs are major barriers. 5 In Nigeria, the prevalence of modern contraceptive use was 14.2%. 6 According to Nigeria Demographic and Health Survey (NDHS), the use of modern contraceptive method was higher among sexually active unmarried women (28%) than among married women (12%). Among currently married women, the prevalence of contraception, regardless of method, was 17%. 7 In the five years prior to the survey, two out of every five women (41%) who started using a contraceptive method stopped within a year, indicating large discontinuation rate. While the desire to become pregnant was the most common reason for discontinuance (35%). Sexually active unmarried women had a larger unmet need for FP (48%) than currently married women (19%). 7 Considering the challenges in achieving global, regional, national and sub-national contraceptive use targets, adding another voluntary contraceptive option to the method mix will help women to properly time and space their pregnancies for the healthiest and safest outcomes. Subcutaneously administered depot-medroxyprogesterone acetate (DMPA-SC) is a contraceptive injectable formulation that provides women with another voluntary FP option. 8 It offers favourable characteristics such as cost and time savings. It has the potential not only to be administered by a range of health care cadres, but can be self-injected.

The Government of Nigeria pledged to achieve modern contraceptive prevalence rate (mCPR) target of 27% by 2020. 9 To accelerate the progress toward that goal, DMPA-SC (brand name Sayana Press) was introduced to the contraceptive method mix in 2015. 10 DMPA-SC is seen as a valuable innovation in FP. Compared with other contraceptive methods, the benefits of DMPA-SC include ease of use, few side effects, quick administration, less pain and greater effectiveness. [10] [11] [12] [13] Injectable contraceptives are increasingly popular in Nigeria (as many other African countries) due to their effectiveness, privacy and convenience. 14 DMPA-SC has been paired with an all-in-one syringe (Uniject), 13 creating a single, easy-touse and acceptable product. 15, 16 It has been heralded as a possible "game changer" for FP, due to its easy administration by paraprofessionals like junior community health extension workers, community-based distributors, proprietary and patent medical vendors (PPMVs), or by self-injection. 13 This study is being conducted in coronavirus disease 2019 (COVID-19) era. The first case of COVID-19 was reported in Wuhan, China, on December 8, 2019. 17 On December 31, 2019, Chinese health authorities contacted the World Health Organization (WHO), which declared the outbreak a Public Health Emergency of International Concern by January 30, 2020. 18 Due to its high spread and mortality across many countries, COVID-19 was declared a pandemic on March 11, 2020. 19 The impact of COVID-19 on sexual and reproductive health was worrisome. 20 The lack of contraceptive drugs and devices as a result of supply chain disruption was one of the most significant impediments to access. 21 In Nigeria, clients were hesitant to visit health facilities for FP commodity uptake. Interestingly, the implementation of resilient and accelerated scale-up of DMPA-SC in Nigeria (RASuDiN) coincided within the COVID-19 era. The project has a community component used to reach clients who are unwilling or unable to visit health facilities due to COVID-19. Also, it was crucial in expanding FP method choice, an indication of the potential for contraceptive use and scale-up in Nigeria. The objective of this study was to examine the trend in DMPA-SC use across selected Nigerian states.

The study location is Nigeria, the most populous country in Africa with a population of 191 million. 22 Nigeria has a weak health delivery system that contributes to adverse maternal health outcomes, 23, 24 including failure in birth control programs. Moreover, the health delivery system in Nigeria is grossly underfunded. 25 The national indices of maternal health, particularly in the use of vital healthcare services is among the poorest in the world. 26 In the 5 years preceding the 2018 Nigeria Demographic and Health Survey (NDHS), modern contraceptive use was about 28% among sexually active unmarried women and 12% among currently married women. The unmet need for FP was 48% among sexually active unmarried women and 19% among currently married women. 7 These show that the use of contraceptive methods was low, worrisome and needs improvement. To achieve the 27% mCPR, the Nigerian government developed; a) National Communication Plan (2017-2020); b) national guideline and training manuals for the introduction and scale-up of DMPA-SC self-injection (2019); c) manual for the Training of Doctors, Nurse/Midwives and Community Health Extension Workers on Postpartum Family Planning (2016); and d) task shifting/task sharing policy for essential health care services in Nigeria as well as the standard of practice (SOP). The implementation of these programs could in no small measure enhance contraceptive use in Nigeria 

We used time series data collected retrospectively from health clinic encounter between August 2019 and July 2020 across the RASuDiN project states. The National Health Management Information System (NHMIS) FP Register was used to capture client information at the health facilities. The data was extracted over a period of 12 months to determine the trend of DMPA-SC uptake in public health facilities in Anambra, Delta, Enugu, Kwara, Lagos, Niger, Ogun, Oyo, Plateau and Rivers states. Association of Reproductive and Family Health (ARFH) is the principal recipient of the grant and manages the project data.

In 2016, the Federal Ministry of Health, Nigeria authorized the introduction of DMPA-SC in health facilities. Nurses and midwives administered DMPA-SC at health facilities, adding to their routine FP service provision. In the commencement of the RASuDiN project in 2018, healthcare service providers and community-oriented resource providers (CORPS) were trained on DMPA-SC. This was similar to a previous approach where community health workers and facilitybased health care providers in Benin were trained to administer DMPA-SC safely and effectively in 10 health zones. 27 Community-based DMPA-SC service delivery is becoming popular, particularly among new users of contraception and could help the country achieve its FP goals. Table 1 has the details of the project Nigerian states, number of Local Government Areas (LGAs) per state and the number of public health facilities (primary, secondary and tertiary) in each state.

The data was collected across all intervention health facilities in the 10 RASuDiN project states (Anambra, Delta, Enugu, Kwara, Lagos, Niger, Ogun, Oyo, Plateau and Rivers). These include both those reporting on District Health Information System (DHIS) or otherwise. At community level, each CORPs on the RASuDiN project was attached to a health facility where their service delivery data are entered into the NHMIS FP register. The facility FP providers in turn collates the entire data (both health LGAs in the 10 implementing project states. The supervisors also ensure completeness and timely submission of monthly reports.

The new acceptors and revisits for DMPA-SC (health facility provider-administered, CORPS-administered and self-injection) were measured in the 10 RASuDiN project states (Anambra, Delta, Enugu, Kwara, Lagos, Niger, Ogun, Oyo, Plateau and Rivers). In addition, the number of health clinics providing DMPA-SC for each month was determined across the project states.

Ethical approval was obtained from National Health Research Ethics Committee (NHREC) of Nigeria -Protocol approval number: NHREC/01/01/2007-17/10/ 2018. In addition, permission was obtained from individual State Ministry of Health to conduct the research.

The total number of clients who received DMPA-SC through health facility staff, CORPS and self-injection were summarized in counts. Time series analysis approach was used to determine the trend of DMPA-SC uptake over a 12-month period; August 2019 through July 2020. The linear trend model was adopted due to lowest measure of dispersion and/or highest adjusted coefficient of determination (R 2 ). This approach follows the method adopted by previous authors. 28 Statistical significance was determined at 5%. Data analysis was conducted using Minitab version 17.0. Minitab provides user-friendly approach for time series modeling and forecasting. It provides several statistical models, and graphical tools that make results on time series analysis simpler.

Trend Analysis for Health Facility Providers', CORPS-Administered and Self-Injection DMPA-SC Clients

In Figure 1 , the use of DMPA-SC showed an upward trend among clients who received the service through health facility staff in the 10 RASuDiN project states over a period of 12 months (August 2019 -July 2020). See Figure 1 below for the details. Table 2 showed the reported number of facility clients, the predicted number of facility clients and the residual. Based on the linear trend model (Yt = 3799.7 +1308.3*t), for every unit increase in months, the average number of women expected to receive DMPA-SC will increase by 1308.3. The adjusted coefficient of determination was 99.9% which showed very good model fitness.

Linear Trend Equation: Yt = 3799.7 +1308.3*t. Adjusted R 2 = 99.9%. Based on Figure 2 results, there was an upward trend in the use of DMPA-SC among clients who received the service through CORPS in the 10 RASuDiN project states over a period of 12 months (August 2019 -July 2020). See Figure 2 for the details.

The results showed reported number of CORPS clients, the predicted number of CORPS clients and the residual. Based on the linear trend model (Yt = −1030.8 +756.73*t), for every unit increase in months, the average number of women expected to received DMPA-SC through CORPS will increase by 756.73. The adjusted coefficient of determination was 99.9% which showed very good model fitness. See Table 3 for the details.

Linear Trend Equation: Yt = −1030.8 +756.73*t. Adjusted R 2 = 99.9%. Figure 3 showed the use of DMPA-SC had an upward trend among clients who self-injected in the 10 RASuDiN project states over a period of 12 months (August 2019 -July 2020). See Figure 3 below for the details.

In Table 4 , we presented the reported number of selfinjection clients, the predicted number of self-injection In Table 5 , the number of DMPA-SC delivery points were summarized in counts across project states and over time (August 2019 through July 2020). The total number of service delivery points was highest in Delta State (n= 4583), followed by Enugu State (n= 4086) and Oyo State (n= 4006). However, Plateau State had the least service delivery points (n= 864). The total number of service delivery points across the ten project states was 30,797.

Notably, the number of DMPA-SC delivery points which reported data increased over time from August 2019 to July 2020. See Table 5 for the details.

In Table 6 , we showed the number of new acceptors and revisits of DMPA-SC clients who received the method through health facility staff and CORPS respectively, across RASuDiN project states and over a period of 12 months (August 2019 -July 2020). In addition, we presented the total number of clients (new acceptors and revisits) who received DMPA-SC across RASuDiN project states and over 12 months. In sum, the number of clients who received DMPA-SC increased as time increases. The DovePress results also showed that the number of DMPA-SC clients varied across the project states with Niger (32,988) and Oyo (31,511) states reporting the highest number of clients. See Table 6 for the details.

To the best of our knowledge, this is the foremost study to measure the trend of provider-administered and selfinjection of DMPA-SC in Nigeria counselling and self-injection. Moreover, the village health workers are to serve as public sector community-level providers of DMPA-SC, pharmacies and Patent and Proprietary Medicine Vendors (PPMVs) would be able to legally stock and administer DMPA-SC and the junior community health extension workers would provide the service too. 30 The findings are consistent with the results of previous studies which found an upward trend in modern contraceptive use over time especially among young women. 31, 32 The upward trend could be due to changes in contraceptive use behaviour through increased awareness creation. In a previous study, about two-thirds of the increase in modern contraceptive use was due to change in contraceptive use behaviour. 33 Most importantly, the increased number of clients over time could be due to the changes in contraceptive use behaviour among the rural population and among religious women as a result of gatekeepers' buy-in for the project. 31 Decision makers or gatekeepers involvement in FP could be a major motivator for women's uptake of contraceptive. 33 In our project, DMPA-SC is only a method mix to other FP commodities and clients are able to make their choice. A previous study on DMPA-SC in Nigeria reported many users choose DMPA-SC due to recommendations from providers and friends, and the experience of less side effects. 34 Proper counselling is a determining factor for contraceptive methods use in general and DMPA-SC uptake in particular. 10 In RASuDiN project, clinicians/nurses and CORPS conduct counselling at health facilities and at communities as directed in national guideline.

Another possible reason for the upward trend could be the availability of commodities across the project states. Since the DMPA-SC introductory program in Nigeria, distribution of commodity has been amplified especially to high volume providers and high demand settings. 34 

Moreover, community-based distribution has been an effective service delivery model for the hard-to-reach, most-at-risk of unmet need for FP and the key population such as the young and unmarried users. Women who are motivated to uptake contraceptive use for reasons such as benefits of a method, economic situation, suitability of a methods and fear of unwanted pregnancy, now have DMPA-SC available, assessable and without fee. 33 No doubt, the availability, accessibility and free commodity/ service for DMPA-SC may have contributed to the upward trend.

There are many unintended pregnancies in Nigeria, 35 which seems to indicate a large unmet need for contraceptive use. 36 However, the myth and misconception about the side effects of modern contraceptives, 37 may have contributed to low contraceptive use. Moreover, what was lacking was the political will to implement FP programs on a much larger scale, using community-oriented approaches and communication programs, to help change the myth about the side effects of modern contraceptives. But it seems the Nigerian government has arisen to her responsibility recently. This is why DMPA-SC is becoming the game changer in the FP method mix. DMPA-SC is safe with minimal side-effects. In a longitudinal study in Nigeria, 810 clients who used DMPA as a contraceptive method were followed over a period of 11 years. In the end, amenorrhea, weight gain, weight loss, metrorrhagia and menorrhagia were the reasons for discontinuation of DMPA in only 11% of the patients. 38

The total saturation approach in the implementation of RASuDiN project makes a plausible representation of the project states. The participation of key stakeholders during the monthly data validation meetings and the measures of data validation, make the results of this study very dependable. However, our sample of DMPA-SC users in 10 out of 36 states + Federal Capital Territory in Nigeria is unlikely to be representative of the Nigerian population of reproductive age women. These data would not be considered representative, as there is no denominator to determine the rate. The data consist of counts of patient encounters. Further, because this analysis is restricted to service data, client motivations for using family planning for the first time or choosing to switch to DMPA-SC from another method cannot be determined. It is possible that increase in the use of DMPA-SC may have been overestimated due to the use of absolute count rather than a rate. 

We have found an increasing number of women adopting and continuing to utilize DMPA-SC as a form of birth control in Nigeria. While there is a large focus on the uptake and continuation of DMPA-SC, more concerted efforts are needed to scale-up the intervention to other parts of Nigeria. More women can be encouraged to uptake or continue contraceptive use. We recommend that attention should be paid to improving the quality of counseling about side effects of contraceptive use, and particularly those related to amenorrhea, weight gain, weight loss, metrorrhagia, menorrhagia and bleeding as to enhance universal acceptability of contraceptive use in Nigeria.
