在不列颠哥伦比亚省发现了儿科炎性肠病 (IBD) 集群,与空气污染和农业农药有关. 这些环境因素,以及种族,影响儿科IBD发病率.
科学领域:
- 环境流行病学环境流行病学
- 儿科胃肠病学 儿科胃肠病学
- 空间分析 空间分析
背景情况:
- 炎症性肠病 (IBD) 的地理集群表明环境影响,但北美儿科IBD (PIBD) 的空间模式仍然没有特征.
- 这项研究调查了加拿大不列颠哥伦比亚省 (BC) 的 PIBD 的地理空间集群,假设与种族和环境暴露的关联.
研究的目的:
- 在不列颠哥伦比亚省确定儿科IBD (PIBD) 的空间集群.
- 模拟PIBD发病率模式与人口种族,农村,社会经济因素和环境暴露之间的关联.
主要方法:
- 利用了1,183名被诊断患有IBD的儿科患者 (年龄≤16.9岁,2001-2016) 的临床注册表,并使用了有效的邮政编码.
- 采用空间集群检测程序来识别高和低发病率区域.
- 使用波桑率模型进行生态分析,评估IBD,克罗恩病 (CD) 和性结肠炎 (UC) 发病率与种族,农村,家庭规模,收入,绿色空间,空气污染 (PM2.5),紫外线和农药应用.
主要成果:
- 在大温哥华,奥卡纳根南部和温哥华岛确定了PIBD,CD和UC发病率热点,在不列颠哥伦比亚省东南部和北部有冷点.
- PIBD的新风险因素包括细颗粒物 (PM2.5) 空气污染和农业石油杀虫剂的应用.
- 南亚族裔是一个危险因素,而土著族裔,更大的家庭规模和夏季更高的紫外线暴露对PIBD产生了保护作用.
结论:
- 在不列颠哥伦比亚省确定了儿科IBD (PIBD) 的空间集群,与已知的和新的环境决定因素相关.
- 细颗粒物 (PM2.5) 空气污染和农业农药使用成为需要进一步调查的重大新风险因素.
- 这些发现强调了环境暴露和种族在儿科IBD病因学中的作用.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
