背景：肠道寄生虫感染对发展中国家的学龄儿童构成巨大的公共卫生挑战。本研究的目的是评估A. lumbricoides，T.中国西南部农村小学生中的鞭毛虫和隐孢子虫。方法：2014年采用以学校为基础的横断面研究方法，对西南地区321名小学生进行问卷调查。他们被邀请提供粪便样本，并就卫生状况和卫生行为进行访谈。粪便标本进行A.蚯蚓和T.鞭毛虫使用加藤-卡茨粪便厚涂片技术。隐孢子虫的存在，确定使用改良的抗酸染色法。结果：A型血吸虫感染率为10.0%（95% CI：6.9-13.8%）;蛔虫为25.2%（95% CI：20.6-30.4%）;隐孢子虫为2.4%（95%CI：1.1-4.9%）。合并感染率为3.7%（95%CI：1.9-6.4%）。蛔虫/T.毛尾螨为0.3%（95% CI：0 ~ 1.7%）。蚯蚓/隐孢子虫和T.的0.9%（95%CI：0.2-2.7%）。毛尾/隐孢子虫属。来自使用井水或河水的家庭的儿童患A的几率更大。蛔虫感染（aOR = 2.61，95% CI：1.12-6.05）。有一个家庭厕所与T。鞭毛虫感染（aOR = 0.50，95% CI：0.30-0.84）。平日在学校食堂吃三餐的儿童感染隐孢子虫的风险较低。使用泉水作为水源与任何肠道感染的几率较低相关（aOR = 0.56，95%CI：0.35-0.91）。结论：我们的研究呼吁学校为基础的驱虫结合健康教育，卫生宣传和提供安全饮用水和改善卫生设施的干预计划。
Background: Intestinal parasitic infections pose great public health challenges in school children in developing countries. The aim of this study was to assess the prevalence of A. lumbricoides, T. trichiura and Cryptosporidium among elementary school children in rural southwestern China. Methods: A school-based cross-sectional study involving 321 elementary school children was conducted in 2014 in the southwest of China. They were invited to provide a stool sample and interviewed about the sanitary situation and hygiene behavior. Stool specimens were examined for A. lumbricoides and T. trichiura using the Kato-Katz fecal thick-smear technique. The presence of Cryptosporidium was determined using a modified acid-fast staining method. Results: The prevalence of infection was 10.0% (95% CI: 6.9–13.8%) for A. lumbricoides, 25.2% (95% CI: 20.6–30.4%) for T. trichiura and 2.4% for (95% CI: 1.1–4.9%) Cryptosporidium. The prevalence of co-infection was 3.7% (95% CI: 1.9–6.4%) for A. lumbricoides/T. trichiura, 0.3% (95% CI: 0–1.7%) for A. lumbricoides/Cryptosporidium and 0.9% (95% CI: 0.2–2.7%) for T. trichiura/Cryptosporidium. Children from households using well or river water were associated with a greater odds of A. lumbricoides infection (aOR = 2.61, 95% CI: 1.12–6.05). Having a household lavatory was associated with a lower odds of T. trichiura infection (aOR = 0.50, 95% CI: 0.30–0.84). Children who had three meals at the school canteen on week days were at a lower risk of Cryptosporidium infection. The use of spring water as a water source was associated with lower odds of any intestinal infection (aOR = 0.56, 95% CI: 0.35–0.91). Conclusions: Our study calls for an intervention program of school-based deworming combined with health education, hygiene promotion and provision of safe water and improved sanitation.
