Abstract

Background: Schistosomiasis is one of the parasitic diseases of poverty caused by larval forms of trematode worms. Individuals get infected upon contact with water infected by these larvae through skin penetration. Thus, poor people without access to basic water and sanitation services, among others are more likely to contract the disease. The greatest burden of the disease is found in Africa where over 200 million people require preventive treatment. Given that Africa has experienced economic growth in recent times, albeit with some declines, this study investigated the effect of per capita income on the prevalence of schistosomiasis in selected countries on the continent.

Methods: The study employed panel data on 35 African countries over the period 2002-2019. The data were obtained from the Global Burden of Diseases Study (GBD) 2021 database and the World Bank's World Development Indicators (WB's WDI) database. Prevalence of schistosomiasis i) among males and females (overall), ii) among males and iii) among females were used as the baseline dependent variables. Three other indicators of schistosomiasis were used for robustness purposes. The growth rate of Gross Domestic Product (GDP) per capita (per capita income) was used as the main independent variable. The dynamic panel system Generalised Method of Moments (GMM) regression was employed as the empirical estimation technique.

Results: In the baseline, the study found a negative significant effect of per capita income on the prevalence of schistosomiasis (overall prevalence of schistosomiasis (β = -0.021, p < 0.05), prevalence of schistosomiasis among males (β = -0.04, p < 0.01) and prevalence of schistosomiasis among females (β = -0.04, p < 0.01)). The findings were not qualitatively different when the three other indicators of schistosomiasis were used.

Conclusion: Enhancing per capita income on the African continent remains critical towards the fight against schistosomiasis. Therefore, measures such as educational and skills development, technological advancement, among others, that can enhance per capita income should be deepened by governments, firms (including financial institutions) and other stakeholders.

在选定的非洲国家,人均收入对血吸虫病流行的影响:一项小组研究。
背景:血吸虫病是由吸虫幼虫引起的一种贫困寄生虫病。个体通过皮肤接触被这些幼虫感染的水就会被感染。因此,除其他外,无法获得基本水和卫生服务的穷人更有可能感染这种疾病。这种疾病的最大负担出现在非洲,那里有2亿多人需要预防性治疗。鉴于非洲近年来经历了经济增长,尽管有一些下降,本研究调查了人均收入对非洲大陆某些国家血吸虫病流行的影响。方法:该研究采用了2002年至2019年期间35个非洲国家的面板数据。这些数据来自《2021年全球疾病负担研究》数据库和世界银行的《世界发展指标》数据库。血吸虫病患病率i)男性和女性(总体),ii)男性和iii)女性被用作基线因变量。为了稳健性目的,使用了其他三个血吸虫病指标。人均国内生产总值(GDP)增长率(人均收入)作为主要自变量。采用动态面板系统广义矩量法(GMM)回归作为经验估计技术。结果:在基线中,研究发现人均收入对血吸虫病患病率(总体血吸虫病患病率(β = -0.021, p)有显著的负影响。结论:提高非洲大陆的人均收入对于抗击血吸虫病仍然至关重要。因此,诸如教育和技能发展、技术进步等能够提高人均收入的措施应由政府、企业(包括金融机构)和其他利益相关者深化。
