Item Mapping local patterns of childhood overweight and wasting in low- and middle income countries between 2000 and 2017(Elsevier, 2020) Kinyoki, J. R.; Lazzar-Atwood, A.; Lain Hay, S.; Oluwasanu, M. MA double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4% (62.3 (55.1–70.8) million) to 6.4% (58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2% (30 (22.8–38.5) million) in 2000 to 6.0% (55.5 (44.8–67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria. Our estimates provide a new perspective to researchers, policy makers and public health agencies in their efforts to address this global childhood syndemic.Item Global, Regional, and National Cancer Incidence, Mortality, Years of Life Lost, Years Lived With Disability, and Disability-Adjusted Life-Years for 29 Cancer Groups, 1990 to 2017. A Systematic Analysis for the Global Burden of Disease Study(American Medical Association (AMA), 2019) Fitzmaurice, C.; Abate, D.; Olagunju, A. T.; Olagunju, T. O.; Oluwasanu, M. M.; Omonisi, A. EImportance: Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data. Objective: To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning. Evidence Review: We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence. Findings: In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572 000 deaths and 15.2 million DALYs), and stomach cancer (542 000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819 000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601 000 deaths and 17.4 million DALYs), TBL cancer (596 000 deaths and 12.6 million DALYs), and colorectal cancer (414 000 deaths and 8.3 million DALYs). Conclusions and Relevance: The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care.Item Ensuring health security for Nigerians by 2050: closing the equity gaps in reproductive health(BioMed Central, 2019) Abiona, O.; Oluwasanu, M.; Oladepo, O. O.Background: Reproductive health is a key foundation for strategies to address health security. It constitutes a vital element in the vision to achieve improved health, quality of life and well-being of individuals and families and the realisation of national economic goals. Developing a blue print for health security in reproductive health matters may contribute to closing the equity gaps in Nigeria by the year 2050. Methods: Gaps in reproductive health were identified through situation analysis of selected reproductive health indices. SWOT analysis was also conducted to outline areas of strengths and opportunities, in addition to weaknesses and threats. Key reproductive health indicators were forecasted for 2050. Results: Despite all efforts, gaps still exist in the country’s reproductive health indices including maternal, perinatal, contraceptive, abortion and gynaecological. Most pregnancy-related deaths are linked largely to preventable causes. If unaddressed, these challenges would undermine gains from previous interventions and responses from governmental and non-governmental organizations and pose serious threats to the nation’s health security. Conclusions: The country must be committed to reproductive health agenda that is focused on the International Conference on Population and Development goal in its bid to achieve health security by the year 2050. Due considerations must be accorded to emerging reproductive health issues like men’s reproductive health and their involvement intheir partners’ reproductive health, and the reproductive health needs of the aged, people with disabilities and those in humanitarian settings. Further in achieving health security for Nigerians by the year 2050, the principles underlying the reproductive health policy of the country must be upheld. These include equity, right based approach, gender and age responsiveness, cultural sensitivity and continuum of care amongst others.Item Analysis of alcohol policy in Nigeria: multi-sectoral action and the integration of the WHO “best-buy” interventions(Springer Nature, 2019) Adebayo, A. M.; Oluwasola, T. A. O.; Oluwasanu, M. M.; Fawole, A. O .Background: Harmful alcohol use is a modifiable risk factor contributing to the increasing burden of non-communicable diseases and deaths and the implementation of policies focused on primary prevention is pivotal to address this challenge. Policies with actions targeting the harmful use of alcohol have been developed in Nigeria. This study is an in-depth analysis of alcohol-related policies in Nigeria and the utilization of WHO Best Buy interventions (BBIs) and multi-sectoral action (MSA) in the formulation of these policies. Methods: A descriptive case study design and the Walt and Gilson framework of policy analysis was utilized for the research. Components of the study included a scoping review consisting of electronic search of Google and three online databases (Google Scholar, Science Direct and PubMed) to identify articles and policy documents with no language and date restrictions. Government institution provided documents which were not online. Thirteen policy documents, reports or articles relevant to the policy formulation process were identified. Other components of the study included interviews with 44 key informants (Bureaucrats and Policy Makers) using a pretested guide. The qualitative data were coded and analyzed using thematic analysis. Results: Findings revealed that policy actions to address harmful alcohol use are proposed in the 2007 Federal Road Safety Act, the Non-communicable Diseases Prevention and Control Policy and the Strategic Plan of Action. Only one of the best buy interventions, (restricted access to alcohol) is proposed in these policies. Multi-sectoral action for the formulation of alcohol-related policy was low and several relevant sectors with critical roles in policy implementation were not involved in the formulation process. Overall, alcohol currently has no holistic, health-sector led policy document to regulate the marketing, promotion of alcohol and accessibility. A major barrier is the low government budgetary allocation to support the process. Conclusions: Nigeria has few alcohol-related policies with weak multi-sectoral action. Funding constraint remains a major threat to the implementation and enforcement of proposed policy actions.Item Contextual factors influencing the roles of patent medicine vendors in the provision of injectable contraception services in Nigeria(Springer Nature, 2023) Adebayo, A. M.; Oluwasanu, M. M.; Okunade, F. T.; Ajayi, O. O.; Akindele, A. O.; Ajuwon, A. J.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.Item Intention and Concerns about HPV Vaccination among In-School Adolescents in Ibadan, Oyo State, Nigeria(Nigerian Medical Association, 2023) Adeniyi, F. I.; John‑Akinola, Y. O.; Oluwasanu, M. M.; Oluwasanu, M. M.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.Item Temporal trends in overweight and obesity and chronic dease risks among adolescents and young adults: A ten-year review at a tertiary institution in Nigeria(Public Library of Science (PLoS), 2023) Oluwasanu, A. O.; Akinyemi. J. O.; Oluwasanu, M. M.; Oseghe, O. B.; Oladoyinbo, O. L.; Bello, J.; Ajuwon, A. J.; Jegede, A. S.; Danaei, G.; Akingbola, O.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.Item Cervical cancer and human papillomavirus vaccine knowledge, utilisation, prevention educational interventions and policy response in Nigeria: a scoping review(SAGE Publishing, 2022) John-Akinola, Y. O.; Ndikom, C. M.; Oluwasanu, M. M.; Adebisi, T.; Odukoya, O.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.Item Prevalence of physical activity and dietary patterns as risk factors for cardiovascular diseases among semi-urban dwellers in Ibadan, Nigeria(African Health Sciences Publishing Association, 2022) Aduroja, P. E.; John‑Akinola, Y. O.; Oluwasanu. M. M.; Oladepo, O.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.Item Breast cancer in adolescents and young adults less than 40Years of age in Nigeria: a retrospective analysis(Hindawi Limited, 2022) Ntekim, A.; Oluwasanu, M.; Odukoya, O.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. Results. 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.
