    Effect of public health expenditure on health outcomes in Nigeria and Ghana
    (2022) Oladosu AO; Chanimbe T; Anaduaka US
    Despite the prevailing literature examining the effect public health expenditure has on health outcomes in Africa, Malaria and HIV/AIDS mortality which are key indicators of the outcome variable were unconsidered when drawing inferences. In view of this oversight, we investigate the impact of public health expenditure on health outcomes in Nigeria and Ghana whilst reconceptualizing health outcome by capturing infant, maternal, Malaria and HIV/AIDS mortality. Using the health expenditure commitment at the 1999 United Nations General Assembly and the Abuja Declaration of 2000, we also assessed public policy’s role in this relationship via linear regression analysis. With hindsight, our findings disclosed a low public health expenditure in both countries despite the Ghanaian case revealing a negative relationship, which was primarily insignificant whilst Nigeria indicated a positive one. These empirical evidences accentuate the need to augment public health expenditure in both countries to boost health outcomes whilst bringing to bear the significant influence of GDP, school enrolment and residing in urban areas on health outcomes.

    Plastic pollution in the environment in Nigeria: A rapid systematic review of the sources, distribution, research gaps and policy needs
    (2022) Yalwaji B; John-Nwagwu HO; Sogbanmu TO
    Plastic are emerging pollutants requiring urgent intervention for its management. In African countries like Nigeria, the evidence to inform plastic pollution management is scanty. This rapid review aimed to systematically evaluate evidence on the distribution, sources, biological effects, research gaps and policy needs of plastic pollution in various environmental matrices in Nigeria. Peer-reviewed journal articles on nano-, micro-, meso- and macroplastics contamination of water, sediment, air, soil and biota were accessed from PubMed, Google Scholar and Science Direct. They were screened, comprehensively revised and critically appraised for inclusion, data extraction and evidence synthesis. A total of 358,974 articles were accessed from any publication date up till May 30, 2021. Only 34 articles met the inclusion criteria and critical appraisal. Only 26 of the included studies reported the distribution, levels and/or effects of microplastics (MPs) (n = 12), macroplastics (n = 12) or both (n = 2) in water, sediment, biota, food and/or land. Only 15 of the 36 states and the Federal Capital Territory had any data on micro- and/or macroplastics. Macroplastics from land-based sources were mainly reported from educational institutions, residential areas and markets. Plastic sources reported were tire wear, cigarette butts, fishing ropes and gears, plastic bags, water sachets and e-wastes. Biological effects (oxidative stress, neurotoxicity, reduced plant root biomass) of virgin MPs were reported in crab, African catfish and lime tree only in laboratory experiments. Microplastic data in biota were limited to selected fish species, aquatic insects and gastropods. Only one (1) study on plastics in waterbodies in Northern Nigeria (Kogi State) was found. Research gaps on plastic distribution in terrestrial biota, other aquatic biota, soil, air, ground and potable water sources as well as biological effects were identified. Policy needs for plastic pollution management identified include stakeholder education, polymer replacement, recycling, tax and incentives to support the sustainability of life below water and on land (UN SDGs 14 and 15).

    Validation of the fear of the COVID-19 scale in Nigeria: Implications for public health practice
    (2021) Chia T; Oyeniran OI; Iorfa SK
    Objective The fear of the COVID-19 pandemic has affected a wide range of health-related attitudes and behaviours worldwide. However, within an African population, it is not clear how the fear of the COVID-19 pandemic may be particularly important for formulating public health policies and their consequent implementation. As a first step, it is important to validate a psychometrically sound instrument to assess the fear of the COVID-19 pandemic using an African population. This study presents a preliminary validation of the fear of the COVID-19 Scale (FCV-19S) using a sub-Saharan African population from Nigeria. Methods Three hundred and eighty-nine people responded from a total of 1000 invitees. The participants were requested to fill a web-based (Google forms) FCV-19S questionnaire. The responses, together with their socio-demographic data, were analysed using descriptive statistics and a confirmatory factor analysis. Results The age of the participants ranged between 21 and 30 years (mean 25.84 years). The study participants comprised 220 males (56.6%) and 169 females (43.4%). The factor loadings of all seven items of the FCV-19S questionnaire reached statistical significance and, therefore, were retained. The confirmatory factor analysis indicated that the two-factor structure of the FCV-19S questionnaire was a better fit for the Nigerian subpopulation under consideration. Cronbach's alphas for both subscales were acceptable. Conclusions The FCV-19S is a valid, suitable, and effective tool for the African population. Additionally, the implications of its use for public health practice in Africa are essential.
