Despite being a priority population in malaria elimination, there is scant literature on malaria-related behavior among gold miners. This study explores the prevalence and factors influencing malaria prevention, care seeking and treatment behaviors in Guyana gold mining camps. A cross sectional survey was conducted among adult gold miners living in mining camps in the hinterland Regions 1 (Barima-Waini), 7 (Cuyuni-Mazaruni), and 8 (Potaro-Siparuni). Multivariable logistic regressions explored factors associated with miners' self-report of mosquito net use, prompt care-seeking; self-medication; and testing for malaria. A third of miners used a mosquito net the night preceding the survey and net use was higher among those who believed that net use was the norm in their camp (aOR: 3.11; 95% CI:1.65, 5.88). Less than half (45%) of miners had a fever in the past 12 months, among whom 36% sought care promptly, 48% tested positive for malaria while 54% self-medicated before seeking care. Prompt care-seeking was higher among miners with high malaria knowledge (aOR: 1.44; 95% CI: 1.01, 2.05). Similarly, testing rates increased with secondary education (aOR: 1.71; 95% CI: (1.16, 2.51), high malaria knowledge (aOR: 1.45; 95% CI: 1.02, 2.05), positive beliefs regarding malaria transmission, threat, self-diagnosis, testing and treatment, and, trust in government services (aOR: 1.59; 95% CI (1.12, 2.27) and experience of a prior malaria episode (aOR: 2.62; 95% CI: 1.71, 4.00). Self-medication was lower among male miners (aOR: 0. 52; 95% CI: 0.32, 0.86). Malaria prevention and care seeking behaviors among miners are somewhat low and influenced by mosquito net usage, perceived norms, malaria knowledge and prior episode of confirmed malaria. Study findings have implications for malaria interventions in the hinterland regions of Guyana such as the mass and continuous distribution of insecticide treated nets as well as community case management initiatives using trained malaria testing and treatment volunteers to curb malaria transmission among remote gold mining populations. These include efforts to identify and address gaps in distributing mosquito nets to miners and address miners' barriers to prompt care seeking, malaria testing and treatment adherence. Targeted social and behavior change messaging is needed on net acquisition, use and care, prompt care-seeking, malaria testing and treatment adherence. Additional efforts to ensure the overall sustainability of the community case management initiative include increased publicity of the community case management initiative among miners, use of incentives to promote retention rates among the community case management volunteer testers and public private partnerships between the Guyana Ministry of Health and relevant mining organizations.
尽管金矿工人是消除疟疾的重点人群,但关于他们与疟疾相关的行为的文献却很少。本研究旨在探讨圭亚那金矿工人中疟疾预防、就医和治疗行为的流行情况和影响因素。在腹地的 1 区(巴里马-瓦尼)、7 区(库尤尼-马扎鲁尼)和 8 区(波塔罗-锡帕鲁尼)的矿区营地,对成年金矿工人进行了横断面调查。多变量逻辑回归分析了与矿工自我报告的蚊帐使用、及时就医、自我用药和疟疾检测相关的因素。三分之一的矿工在前一天晚上使用了蚊帐,而那些认为营地内使用蚊帐是一种规范的矿工使用蚊帐的比例更高(调整后的比值比:3.11;95%置信区间:1.65,5.88)。不到一半(45%)的矿工在过去 12 个月中有过发热,其中 36%的人及时就医,48%的人疟原虫检测呈阳性,54%的人在就医前自行用药。高疟疾知识水平的矿工更倾向于及时就医(调整后的比值比:1.44;95%置信区间:1.01,2.05)。同样,随着中等教育程度的提高(调整后的比值比:1.71;95%置信区间:1.16,2.51)、高疟疾知识水平(调整后的比值比:1.45;95%置信区间:1.02,2.05)、对疟疾传播、威胁、自我诊断、检测和治疗以及对政府服务的信任(调整后的比值比:1.59;95%置信区间:1.12,2.27)的正向信念,以及疟疾检测呈阳性的既往疟疾发作史(调整后的比值比:2.62;95%置信区间:1.71,4.00),检测率也有所提高。与男性矿工相比,女性矿工的自我用药率较低(调整后的比值比:0.52;95%置信区间:0.32,0.86)。矿工的疟疾预防和就医行为有些偏低,受到蚊帐使用、感知规范、疟疾知识和既往确诊疟疾发作的影响。研究结果对圭亚那腹地地区的疟疾干预措施具有重要意义,如大规模持续发放经杀虫剂处理的蚊帐,以及利用经过培训的疟疾检测和治疗志愿者开展社区病例管理举措,以遏制偏远金矿工人中的疟疾传播。这些措施包括努力确定和解决向矿工分发蚊帐方面的差距,并解决矿工及时就医、疟疾检测和治疗依从性方面的障碍。需要开展有针对性的社会和行为改变宣传活动,包括获取、使用和保养蚊帐,及时就医,疟疾检测和治疗依从性。为确保社区病例管理举措的整体可持续性,还需要增加矿工对该举措的了解,利用激励措施提高社区病例管理志愿者检测员的保留率,并建立圭亚那卫生部与相关矿业组织之间的公私伙伴关系。
