RESUMO

We performed genome-wide association studies of breast cancer including 18,034 cases and 22,104 controls of African ancestry. Genetic variants at 12 loci were associated with breast cancer risk (P < 5 × 10-8), including associations of a low-frequency missense variant rs61751053 in ARHGEF38 with overall breast cancer (odds ratio (OR) = 1.48) and a common variant rs76664032 at chromosome 2q14.2 with triple-negative breast cancer (TNBC) (OR = 1.30). Approximately 15.4% of cases with TNBC carried six risk alleles in three genome-wide association study-identified TNBC risk variants, with an OR of 4.21 (95% confidence interval = 2.66-7.03) compared with those carrying fewer than two risk alleles. A polygenic risk score (PRS) showed an area under the receiver operating characteristic curve of 0.60 for the prediction of breast cancer risk, which outperformed PRS derived using data from females of European ancestry. Our study markedly increases the population diversity in genetic studies for breast cancer and demonstrates the utility of PRS for risk prediction in females of African ancestry.

RESUMO

BACKGROUND: Healthcare workers are currently making efforts to offer services that cater to the holistic care needs of their patients. Previous studies have shown that some healthcare workers encounter challenges when advising patients about Complementary and Alternative Medicine (CAM), even though its use is widespread. Many health care workers may not have received formal education or training in CAM and consequently are unable to address their patients' questions about it. This study explored the knowledge, perception, attitude and practice of CAM by healthcare workers in Garki Hospital, Abuja, Nigeria. METHODS: This was an institution-based cross-sectional study, design and a convergent parallel, mixed methods design was used for data collection. Five (5) healthcare workers were purposively selected as participants for the key informant interviews, while two hundred and fifty (250) selected using a simple random sampling method completed the questionnaire. The data collection instruments used were a key informant interview guide and a 35-item self-administered questionnaire. Knowledge was assessed with a 4-item scale with a maximum score of 8. Perceptions and attitudes were assessed using Likert scales with a maximum score of 45 and 20, respectively. Practice was assessed with a 6-item scale with a maximum score of 18. Qualitative data was analysed using framework analysis. Quantitative data was analysed using descriptive and inferential statistics. Data acquired from both methods were integrated to form the findings. RESULTS: The average age of respondents for the quantitative study was 34.0 ± 7.8 years, and they were predominantly females (61.2%) with one to ten years of work experience (68.8%). The mean knowledge, perception and attitude scores were 1.94 ± 1.39, 13.08 ± 2.34 and 32.68 ± 6.28, respectively. Multiple linear regression result showed that knowledge (t = 2.025, p = 0.044) and attitude (t = 5.961, p = 0.000) had statistically significant effects on the practice of CAM. Qualitative data revealed that the majority of the participants perceive CAM favourably, provided it is properly introduced into mainstream medicine with evidence of safety and research to prove its efficacy. CONCLUSION: The study has shown the gaps in knowledge and the practices of CAM by conventional medical practitioners. This has implications for their ability to counsel and refer patients who may require CAM therapies. Policy, research and programmatic initiatives that seek to enhance their knowledge of CAM, and improve collaboration with CAM practitioners are recommended.

RESUMO

African-ancestry (AA) participants are underrepresented in genetics research. Here, we conducted a transcriptome-wide association study (TWAS) in AA female participants to identify putative breast cancer susceptibility genes. We built genetic models to predict levels of gene expression, exon junction, and 3' UTR alternative polyadenylation using genomic and transcriptomic data generated in normal breast tissues from 150 AA participants and then used these models to perform association analyses using genomic data from 18,034 cases and 22,104 controls. At Bonferroni-corrected P < 0.05, we identified six genes associated with breast cancer risk, including four genes not previously reported (CTD-3080P12.3, EN1, LINC01956 and NUP210L). Most of these genes showed a stronger association with risk of estrogen-receptor (ER) negative or triple-negative than ER-positive breast cancer. We also replicated the associations with 29 genes reported in previous TWAS at P < 0.05 (one-sided), providing further support for an association of these genes with breast cancer risk. Our study sheds new light on the genetic basis of breast cancer and highlights the value of conducting research in AA populations.

RESUMO

PURPOSE: To examine the association between benign breast disease (BBD) and breast cancer (BC) in a heterogeneous population of African women. METHODS: BC cases and controls were enrolled in three sub-Saharan African countries, Nigeria, Cameroon, and Uganda, between 1998 and 2018. Multivariable logistic regression was used to test the association between BBD and BC. Risk factors dually associated with BBD and BC were selected. Using a parametric mediation analysis model, we assessed if selected BC risk factors were mediated by BBD. RESULTS: Of 6,274 participants, 55.6% (3,478) were breast cancer cases. 360 (5.7%) self-reported BBD. Fibroadenoma (46.8%) was the most commonly reported BBD. Women with a self-reported history of BBD had greater odds of developing BC than those without (adjusted odds ratio [aOR] 1.47, 95% CI 1.13-1.91). Biopsy-confirmed BBD was associated with BC (aOR 2.25, 95% CI 1.26-4.02). BBD did not significantly mediate the effects of any of the selected BC risk factors. CONCLUSIONS: In this study, BBD was associated with BC and did not significantly mediate the effects of selected BC risk factors.

RESUMO

Purpose: To examine the association between benign breast disease (BBD) and breast cancer (BC) in a heterogeneous population of African women. Methods: BC cases and matched controls were enrolled in three sub-Saharan African countries, Nigeria Cameroon, and Uganda, between 1998-2018. Multivariable logistic regression was used to test the association between BBD and BC. Risk factors dually associated with BBD and BC were selected. Using a parametric mediation analysis model, we assessed if selected BC risk factors were mediated by BBD. Results: Of 6418 participants, 55.7% (3572) were breast cancer cases. 360 (5.7%) self-reported BBD. Fibroadenoma (46.8%) was the most reported BBD. Women with a self-reported history of BBD had greater odds of developing BC than those without (adjusted odds ratio [aOR] = 1.47, 95% CI: 1.13-1.91). Biopsy-confirmed BBD was associated with BC (aOR = 3.11, 95% CI: 1.78-5.44). BBD did not significantly mediate the effects of any of the selected BC risk factors. Conclusions: In this study, BBD was associated with BC and did not significantly mediate the effects of selected BC risk factors.

RESUMO

BACKGROUND: Patent medicine vendors (PMVs) play vital roles in the delivery of family planning services in Nigeria and other developing countries. There is a growing recognition of the need to integrate them into the formal health care system as a strategy to increase the contraceptive prevalence rate and achieve universal health coverage. Though promising, the success of this proposition is largely dependent on a critical analysis of the factors which influence their operations. This study was designed to identify the contextual factors influencing the provision of injectable contraceptive services by PMVs and the broader effects of their activities on the health system to inform similar interventions in Nigeria. METHODS: This was a qualitative study guided by the UK Medical Research Council's Framework for Complex Interventions. Twenty-seven in-depth interviews were conducted among officials of the association of PMVs, health workers, government regulatory officers and programme implementers who participated in a phased 3-year (2015-2018) intervention designed to enhance the capacity of PMVs to deliver injectable contraceptive services. The data were transcribed and analyzed thematically using NVIVO software. RESULTS: The contextual factors which had implications on the roles of PMVs were socio-cultural and religious, the failing Nigerian health system coupled with government regulatory policies. Other factors were interprofessional tensions and rivalry between the PMVs and some categories of health care workers and increasing donors' interest in exploring the potentials of PMVs for expanded healthcare service provision. According to the respondents, the PMVs bridged the Nigerian health system service delivery gaps serving as the first point of contact for injectable contraceptive services and this increased contraceptive uptake in the study sites. A negative effect of their operation is the tendency to exceed their service provision limits, which has spurred a planned tiered PMV accreditation system. CONCLUSIONS: This study has highlighted the contextual factors which define the roles and scope of practice of PMVs involved in injectable contraceptive service provision. Strategies and interventions aimed at expanding the healthcare delivery roles of PMVs must be encompassing to address the broader contextual factors which underpin their capacities and functions.

RESUMO

There is an increasing prevalence of obesity among college/university students in low- and middle-income countries, similar to the trend observed in high-income countries. This study aimed to describe the trend and burden of overweight/obesity and emerging associated chronic disease risks among students at the University of Ibadan (UI), Nigeria. This is a ten-year retrospective review of medical records of students (undergraduate and post-graduate) admitted between 2009 and 2018 at UI. Records of 60,168 participants were analysed. The Body Mass Index (BMI) categories were determined according to WHO standard definitions, and blood pressure was classified according to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC7). The mean age of the participants was 24.8, SD 8.4 years. The majority were ≤ 40 years (95.1%). There was a slight male preponderance (51.5%) with a male-to-female ratio of 1.1:1; undergraduate students constituted 51.9%. The prevalence of underweight, overweight, and obesity were 10.5%, 18.7% and 7.2%, respectively. We found a significant association between overweight/obesity and older age, being female and undergoing postgraduate study (p = 0.001). Furthermore, females had a higher burden of coexisting abnormal BMI characterised by underweight (11.7%), overweight (20.2%) and obese (10.4%). Hypertension was the most prevalent obesity-associated non-communicable disease in the study population, with a prevalence of 8.1%. Also, a third of the study population (35.1%) had prehypertension. Hypertension was significantly associated with older age, male sex, overweight/obesity and family history of hypertension (p = 0.001). This study identified a higher prevalence of overweight and obesity than underweight among the participants, a double burden of malnutrition and the emergence of non-communicable disease risks with potential lifelong implications on their health and the healthcare system. To address these issues, cost-effective interventions are urgently needed at secondary and tertiary-level educational institutions.

RESUMO

Nigeria is ranked high among African countries in the consumption of alcohol and the national adult per capita consumption was estimated at 12.3litres. Harmful alcohol use is the sixth leading cause of disability and deaths in Nigeria. This study assessed the prevalence and factors associated with alcohol use in selected urban communities in Ibadan, Nigeria. This community-based cross sectional study was conducted among 500 respondents in two selected urban communities in Ibadan, Nigeria. The World Health Organization STEPS tool was used to collect data on socio-demographic characteristics of respondents and the history of alcohol use. Alcohol users were categorized into ever consumed, current consumers, consumers within last 12 months, and frequent consumers within 30 days (low, medium, and high consumers).Chi-square analysis was used to identify factors associated with the different categories of alcohol consumption. The mean age of the respondents was 35.36 ± 12.24 years. Almost one third of the participants (29.0%) reported they had ever consumed alcohol and (13.6%) had consumed alcohol within 30 days prior to the study. Factors significantly associated with the ever-use of alcohol were gender (p = 0.000), and income (p = 0.000). Current use of alcohol had a statistically significant relationship with male gender (p = 0.000). The prevalence of high alcohol use is low in the sample of urban communities studied, and factors influencing include sex, marital status, level of education, income. These results should inform policy decisions to address the alcohol use in urban communities in Southwest Nigeria.

RESUMO

Background: Human papillomavirus (HPV) is a very common sexually transmitted infection responsible for some cancers including cervical cancer. Despite nearly half of the Nigerian population being at risk (women <25), vaccination uptake against the infection is still less than 5%. Methodology: This cross-sectional descriptive survey was conducted using a multi-stage sampling technique. A semi-structured questionnaire was administered to 300 in-school adolescents aged 15-19 years, across 15 private and public secondary schools in Ibadan-North and Ibadan North-West of Oyo State, whose parents gave consent. The data was analysed using descriptive and inferential statistics in SPSS v21. Cronbach's alpha coefficient was used to measure internal consistency reliability while categorical tables were compared using chi-square and regression analysis with a p-value <0.05. Results: The mean age of respondents was 15.8 ± 0.84 years. Half of them were females (52.3%) and also attended private schools (56.3%). Very few of the respondents had heard about HPV (21.0%) and HPV vaccine (12.7%), however, more than half had heard about cervical cancer (55.3%). Few respondents had good knowledge (11.0%) and positive perception (27.0%) of HPV, cervical cancer and HPV vaccine. The major source of information was social media (46.2%). Half of the respondents reported intention to take the vaccine if recommended by their family doctor (56.3%) and if given parental approval (52.0%), however, many (60.7%) were concerned about the vaccine's side effects. Conclusion: Findings show that parents and health workers influence adolescents' HPV vaccination uptake. The study thus recommends the prioritization of parental involvement in HPV vaccination. Parents and health workers should therefore be targeted as key stakeholders in driving the awareness of HPV and uptake of HPV vaccine among adolescents.

RESUMO

PURPOSE: This review evaluated the knowledge, utilisation, prevention education, and policy response across the six geopolitical regions of Nigeria to inform national efforts for the prevention and control of cervical cancer. METHODS: A keyword-based systematic search was conducted in PubMed/MEDLINE (NCBI), Google Scholar, and AJOL electronic databases, including a manual scan of papers, journals and websites to identify relevant peer-reviewed studies. Articles were screened and assessed for eligibility. RESULTS: Many (158) articles were downloaded and after duplicates were removed, 110 articles were included in the final analysis. These were made up of qualitative, quantitative (cross-sectional), intervention and policy studies. Studies have generally reported poor knowledge and awareness of cervical cancer screening but those carried out in urban areas demonstrated a slightly higher level of awareness of Human Papilloma Virus (HPV) vaccine, HPV vaccination uptake and utilization of cervical cancer preventive services than the rural studies. The studies did not show strong government support or policies in relation to cervical cancer control. CONCLUSION: Knowledge and uptake of cervical cancer preventive services across diverse groups in Nigeria remain poor. These could be linked to socio-cultural factors, the lack of an organised cervical cancer screening programme and low financial resource pool for cervical cancer prevention. Therefore, it is necessary to increase government, donor prioritisation and political support in order to ensure increased investment and commitment to cervical cancer elimination in Nigeria.

RESUMO

Background: Breast cancer among adolescents and young adult (AYA) females aged 15-39 years is associated with different patterns of aggressiveness, as well as psychosocial and economic issues. At present, the burden of breast cancer among this age group is unknown in Nigeria. There is a need to determine the proportion of AYA with breast cancer in Nigeria. This will inform the development of breast cancer care programs appropriate for this age group. Objective: The objective of this study was to highlight the burden of breast cancer with an emphasis on AYAs in Nigeria and its implications. Methods: A retrospective review of data from cancer registries in Nigeria between 2009 and 2016 was carried out. Result: s. Among AYA females in Nigeria, breast cancer was by far the most common cancer, constituting 50% of all cancers and 51% (2798 of 5469) of all breast cancer cases. IA third (30.8%) of breast cancer cases in all centers studied were AYAs. Conclusion: The high proportion of AYA with breast cancer is an important feature suggesting that urgent actions are required to ensure early detection and improve breast cancer care among this age group.

RESUMO

PURPOSE: This study investigated the status of training and preparedness for oncology practice and research and degree of interprofessional collaboration among health care professionals in the six geopolitical regions of Nigeria. METHODS: A convergent parallel mixed methods design was used. Three hundred seventeen respondents completed a three-part, online questionnaire. Self-rated competencies in oncology research (26 items), oncology practice (16 items), and interprofessional collaboration (nine items) were assessed with a one- to five-point Likert scale. Six key informant and 24 in-depth interviews were conducted. Descriptive statistics, analysis of variance, and pairwise t-test were used to analyze the quantitative data, whereas thematic analysis was used for the qualitative data. RESULTS: Respondents were mostly female (65.6%) with a mean age of 40.5 ± 8.3 years. Respondents include 178 nurses (56.2%), 93 medical doctors (29.3%), and 46 pharmacists (14.5%). Self-assessed competencies in oncology practice differed significantly across the three groups of health care professionals (F = 4.789, P = .009). However, there was no significant difference across professions for competency in oncology research (F = 1.256, P = .286) and interprofessional collaboration (F = 1.120, P = .327). The majority of respondents (267, 82.4%) felt that educational opportunities in oncology-associated research in the country are inadequate and that this has implications for practice. Key training gaps reported include poor preparedness in data analysis and bioinformatics (138, 43.5%), writing clinical trials (119, 37.5%), and writing grant/research proposals (105, 33.1%). Challenges contributing to gaps in cancer research include few trained oncology specialists, low funding for research, and inadequate interprofessional collaboration. CONCLUSION: This study highlights gaps in oncology training and practice and an urgent need for interventions to enhance interprofessional training to improve quality of cancer care in Nigeria. These would accelerate progress toward strengthening the health care system and reducing global disparities in cancer outcomes.

RESUMO

Background: Physical inactivity and unhealthy diet are leading risk factors for cardiovascular diseases globally. Limited studies have assessed the prevalence of these risk factors in community-based settings in Nigeria. Objectives: This study assessed the prevalence of physical activity and the dietary pattern of residents in selected semi-urban communities in Ibadan, Nigeria. Methods: This was a cross-sectional study carried out among 500 randomly selected residents from two semi-urban communities. Multi-stage random sampling technique was used to select households and participants. Data were collected using a pretested modified version of the WHO STEPS instrument. Descriptive and inferential statistical analyses were determined at 5% level of significance. Results: The mean age was 35.36 ± 12.24 and a mean household size of 4.07 ± 1.85. Majority (87.2%) of the respondents engaged in low physical activity (< 150-300 min/wk). Consumption of fruits and vegetables was low among respondents at 33% and 36.4% respectively. The employment status of respondents was significantly related to expected workplace physical activity level (χ2=11.27; P=0.024). Conclusions: This study highlights the need for the development and implementation of community-driven, multi-layered public health promotion initiatives across different settings.

RESUMO

Human papillomavirus (HPV) vaccine offers protection of between 80 and 100% for anogenital warts and 60-80% in reducing the incidence of pre-malignant lesions from cervical cancer. However, uptake remains low in Nigeria among adolescent girls. This study was a qualitative study that assessed mothers' acceptability and concerns regarding uptake of HPV vaccine by their adolescent daughters. In-depth interviews were conducted with 20 mothers of adolescents girls aged 9-15 years. A snowballing sampling technique was adopted to select the mothers within the community. Consent was obtained for the use of audiotapes, which were transcribed verbatim with thematic analysis of data. Mothers were between the ages of 30-49 years and most of them were traders. Almost all of the women have heard about cervical cancer, but their knowledge about cervical cancer and HPV vaccine was low. Despite their low knowledge, most of the mothers accepted that the vaccine is good and was willing for their adolescent daughters to take the HPV vaccine for the prevention of HPV. However, cost of the vaccine, side effects, and potential exposure of their daughters to promiscuity after taking the vaccine for protection were the major concerns expressed by the mothers as regards to HPV vaccine uptake by their daughters. Findings highlight the need for health promotion and education programs about cervical cancer, HPV, and HPV vaccine to increase awareness and knowledge among mothers of adolescent girls. Also, HPV vaccination should be included as part of routine immunization for female adolescents.

RESUMO

BACKGROUND: Insufficient physical activity (PA) is a growing public health challenge among Nigerian adolescents. Significant information gap exists on the school-related factors which influence the participation of adolescents in school-based physical activity programmes in Nigeria. This study was conducted to document the qualitative views of school principals and teachers on the barriers and opportunities for promoting the physical activity behaviours of adolescents within the school settings in light of the socio-ecological model. METHODS: This was a qualitative study conducted in 12 public and private schools in two local government areas of Oyo state, Nigeria. Two key sources and data collection methods (i.e key informant interviews and focus group discussions) were used. Six key informant interviews were held with school principals and six focus group discussions with classroom teachers using pre-tested guides. Data was analysed using thematic analysis. RESULTS: Fourteen sub-themes were identified as barriers to PA and linked to different levels of the socio-ecological model. Three themes were categorised as parental factors, three themes as socio-cultural and religious factors while the school-related factors had eight sub-themes. Specifically, the school-related barriers were the declining number of trained physical health education teachers, limited opportunities for continuing education and low prioritisation of physical health education. Other school-related factors such as increasing demand for classroom academic time, negative attitudinal dispositions of other teachers and inadequate funding for schools which hampered the provision of facilities and equipment were identified as factors that limit the effective implementation of policies and programmes for physical activity in schools. Opportunities to promote PA within the school settings during assemblies, breaktime, after-school and inter-house sports competition exist. However, these opportunities are hampered by competing academic time, security threats, fear of causalities to students due to poor supervision after school, poor funding and brawling associated with competitive school-based sporting events. CONCLUSIONS: Factors that contribute to insufficient physical activity among in-school adolescents in the school settings are multi-factorial. Implementation of holistic, multi-component interventions which address the social-cultural and school-level factors and enhance students' opportunities for physical activity in schools are recommended.

RESUMO

BACKGROUND: The low utilisation of modern contraceptives in many low- and middle-income countries remains a challenge. Patent medicine vendors (PMVs) that operate in the informal health sector, have the potential to address this challenge. Between 2015 and 2018, the Population Council, in collaboration with the Federal and State Ministries of Health and the Pharmacy Council of Nigeria, trained PMVs in six states to deliver injectable contraceptive services. Outcome evaluation demonstrated increased client uptake of injectable contraceptive services; however, there is limited information on how and why the intervention influenced outcomes. This study was conducted to elucidate the processes and mechanism through which the previous intervention influenced women's utilisation of injectable contraceptive services. METHODS: The study utilised a mixed methods, convergent parallel design guided by the UK Medical Research Council framework. Quantitative data were obtained from 140 trained PMVs and 145 of their clients in three states and 27 in-depth interviews were conducted among relevant stakeholders. The quantitative data were analysed descriptively, while the qualitative data were analysed thematically. RESULTS: The results revealed that even after the completion of the PMV study which had a time-bound government waiver for injectable contraceptive service provision by PMVs, they continued to stock and provide injectables in response to the needs of their clients contrary to the current legislation which prohibits this. The causal mechanism that influenced women's utilisation of injectable contraceptives were the initial training that the PMV received; the favourable regulatory environment as demonstrated in the approval provided by government for PMVs to provide injectable contraceptives for the duration of the study; and the satisfaction and the confidence the female clients had developed in the ability of the PMVs to serve them. However, there were gaps with regards to the consistent supply of quality injectable contraceptive commodities and in PMVs use of job aids. Referral and linkages to government or private-owned facilities were also sub-optimal. CONCLUSION: PMVs continue to play important roles in family planning service provision; this underscores the need to formalize and scale-up this intervention to aid their integral roles coupled with multi-faceted initiatives to enhance the quality of their services.

RESUMO

INTRODUCTION: The control of diabetes depends largely on preventive actions often influenced by knowledge and awareness of the condition, its risk factors, complication, and management. This study assessed the awareness, knowledge, and practices regarding diabetes among adults in two communities in Ibadan, Nigeria. METHODS: A community-based cross-sectional study was conducted among five hundred randomly selected non-diabetic respondents, aged 18 to 65 years. Data was collected using the pretested, modified version of the WHO STEPS instrument translated into Yoruba language. Data collected were analysed using descriptive and inferential analysis and the level of significance was set at p < 0.05. RESULTS: Majority of the respondents (89.6%) had previously heard about diabetes. Of these (n = 448), 31.8% were knowledgeable about diabetes and only 28% have ever had their blood glucose level measured by a doctor or other health professionals. Sex and monthly income were statistically associated with respondents' diabetes knowledge while age, religion, monthly income, employment status, marital status, ethnicity and level of education were statistically associated with screening practices (p < 0.05). Monthly income was found to be a significant predictor of the level of knowledge adjusted by sex. Earning N20,000 ($ 52.60) or less had higher odds of being knowledgeable compared to earning no income (OR 0.54, CI 0.35, 0.83). CONCLUSION: Though Diabetes awareness is high, knowledge gaps and poor screening practices is of concern. This calls for tailored multi-component, community-based, health education interventions.

RESUMO

PURPOSE: This study investigated knowledge and screening practices for cervical cancer among two urban poor community settings in Ibadan, Nigeria. METHODS: A cross-sectional design was used. ODK tool was used to collect quantitative data among a sample size of 500 respondents. Data were analyzed using IBM SPSS version 21 for descriptive and inferential statistics. Scores for knowledge were on a scale of 0-39 points (0-18 low, 19-23 fair, and 24-39 high knowledge). RESULTS: A majority of respondents (77.2%) had low knowledge of cervical cancer and were not aware (93.6%) of the Papanicolaou test (Pap smear test) or cervical cancer screening (91.2%). Very few women (10%) were aware of the human papillomavirus vaccine for the prevention of cervical cancer, 4% had been screened with the Papanicolaou test, and one woman (0.3%) with visual inspection with acetic acid. Four (1.1%) women had taken human papillomavirus vaccine before. CONCLUSION: The findings of this study have underscored a necessity for increased awareness creation through health promotion interventions and strategies to alleviate low knowledge, prevention, and screening practices for cervical cancer in poor community settings in Nigeria.

RESUMO

Introduction: Innovative interventions are needed to address the growing burden of breast cancer globally, especially among vulnerable patient populations. Given the success of Community Health Workers (CHWs) in addressing communicable diseases and non-communicable diseases, this scoping review will investigate the roles and impacts of CHWs in breast cancer screening programs. This paper also seeks to determine the effectiveness and feasibility of these programs, with particular attention paid to differences between CHW-led interventions in low- and middle-income countries (LMICs) and high-income countries (HICs).Methods: A scoping review was performed using six databases with dates ranging from 1978 to 2019. Comprehensive definitions and search terms were established for 'Community Health Workers' and 'breast cancer screening', and studies were extracted using the World Bank definition of LMIC. Screening and data extraction were protocolized using multiple independent reviewers. Chi-square test of independence was used for statistical analysis of the incidence of themes in HICs and LMICs.Results: Of the 1,551 papers screened, 33 were included based on inclusion and exclusion criteria. Study locations included the United States (n=27), Bangladesh (n=1), Peru (n=1), Malawi (n=2), Rwanda (n=1), and South Africa (n=1). Three primary roles for CHWs in breast cancer screening were identified: education (n=30), direct assistance or performance of breast cancer screening (n=7), and navigational services (n=6). In these roles, CHWs improved rates of breast cancer screening (n=23) and overall community member knowledge (n=21). Two studies performed cost-analyses of CHW-led interventions.Conclusion: This review extends our understanding of CHW effectiveness to breast cancer screening. It illustrates how CHW involvement in screening programs can have a significant impact in LMICs and HICs, and highlights the three CHW roles of education, direct performance of screening, and navigational services that emerge as useful pillars around which governments and NGOs can design effective programs in this area.

RESUMO

BACKGROUND: Tuberculosis is the world's deadliest infectious disease and a leading cause of death in Nigeria. The availability of a functional healthcare system is critical for effective TB service delivery and attainment of national and global targets. This study was designed to assess readiness for TB service delivery in Oyo and Anambra states of Nigeria. METHODS: This was a facility-based study with a mixed-methods convergent parallel design. A multi-stage sampling technique was used to select 42 primary, secondary, and tertiary healthcare facilities in two TB high burden states. Data were collected using key informant interviews, a semi-structured instrument adapted from the WHO Service Availability and Readiness Assessment tool and facility observation using a checklist. Quantitative data were analysed using descriptive and inferential statistics while qualitative data were transcribed and analysed thematically. Data from both sources were integrated to generate conclusions. RESULTS: The domain score for basic amenities in both states was 48.8%; 47.0% in Anambra and 50.8% in Oyo state with 95% confidence interval [- 15.29, 7.56]. In Oyo, only half of the facilities (50%) had access to constant power supply compared to 72.7% in Anambra state. The overall general service readiness index for both states was 69.2% with Oyo state having a higher value (73.3%) compared to Anambra with 65.4% (p = 0.56). The domain score for availability of staff and TB guidelines was 57.1% for both states with 95% confidence interval [- 13.8, 14.4]. Indicators of this domain with very low values were staff training for the management of HIV and TB co-infection and training on MDR -TB. Almost half (47.6%) of the facilities experienced a stock out of TB drugs in the 3 months preceding the study. The overall tuberculosis-specific service readiness index for both states was 75%; this was higher in Oyo (76.5%) than Anambra state (73.6%) (p = 0.14). Qualitative data revealed areas of deficiencies for TB service delivery such as inadequate infrastructure, poor staffing, and gaps with continuing education on TB management. CONCLUSIONS: The weak health system remains a challenge and there must be concerted actions and funding by the government and donors to improve the TB healthcare systems.
