Abstract

Background

Geospatial techniques are critical for identifying potential environmental risk factors and implementing effective prevention strategies for chronic diseases. The Mysuru stUdies of Determinants of Health in Rural Adults (MUDHRA)-Cohort was a notable study that systematically investigated the prevalence and risk factors associated with Chronic Bronchitis (CB) in 16 randomly selected villages of Mysuru District between 2006 and 2009. The objective of this study is to spatially visualize the highest prevalence of MUDHRA-CB at village level, and identifying potential environmental risk factors.

Methods

An analysis was conducted on a total of 8457 individuals aged 30 years and older to ascertain the presence of chronic bronchitis symptoms. To assess the prevalence of chronic bronchitis, a door-to-door survey was conducted using international Burden of Obstructive Lung Disease (BOLD) study questionnaires. The thematic map of chronic bronchitis burden was generated using Geographic Information System (GIS) tools and overlaid on the land use and land cover patterns extracted from Remote Sensing (RS) satellite images.

Results

The thematic map identified Karya village has having the highest prevalence (14.82 %), while there were no reported cases of chronic bronchitis in Alatthuru village. The land use land cover map generated showed the presence of a mine located around 310 m from Karya village. Inhalation of dust particles from the mine operations and wind direction could be attributed to the higher prevalence of chronic bronchitis.

Conclusion

Spatial epidemiological research studies that incorporate RS, GIS, and local field studies may aid in identifying potential environmental factors associated with a higher risk of chronic conditions.

慢性支气管炎的地理空间洞察：评估印度Mysuru地区mudhra队列的热点和环境因素

地理空间技术对于识别潜在的环境风险因素和实施有效的慢性病预防战略至关重要。Mysuru农村成人健康决定因素研究（MUDHRA）是一项引人注目的研究，该研究系统地调查了2006年至2009年间Mysuru地区16个随机选择的村庄的慢性支气管炎（CB）患病率和相关危险因素。本研究的目的是在空间上可视化村一级MUDHRA-CB的最高患病率，并确定潜在的环境风险因素。方法对8457名年龄在30岁及以上的人进行分析，以确定是否存在慢性支气管炎症状。为了评估慢性支气管炎的患病率，采用国际阻塞性肺疾病负担（BOLD）研究问卷进行了挨家挨户的调查。利用地理信息系统（GIS）工具生成慢性支气管炎负担专题地图，并叠加从遥感（RS）卫星图像中提取的土地利用和土地覆盖模式。结果专题地图显示，卡里亚村慢性支气管炎患病率最高（14.82%），阿拉图鲁村无慢性支气管炎病例报告。生成的土地利用和土地覆盖地图显示，在距Karya村约310米的地方存在地雷。吸入来自矿山作业和风向的粉尘颗粒可归因于慢性支气管炎的较高患病率。结论结合RS、GIS和当地实地调查的空间流行病学研究有助于识别与慢性病高风险相关的潜在环境因素。
