ABSTRACT

This study aimed to describe: 1) soil-transmitted helminthiasis (STH) and schistosomiasis prevalence and intensity in preschool-age children (PSAC) and school-age children (SAC), 2) schistosomiasis seroprevalence in SAC, 3) undernutrition prevalence in SAC, 4) sanitary toilet coverage in households, and 5) association between STH, Schistosoma japonicum exposure, nutritional status, and sanitation. PSAC and SAC in two Haiyan-stricken provinces were examined using Kato–Katz technique and ELISA Antibody test. Anthropometric and hemoglobin measurements were also obtained. The reported sanitary toilet coverage was validated in a survey. The prevalence of any STH in PSAC and SAC was 50.2% and 41.3%, respectively. Moderate-heavy intensity (MHI) STH prevalence in PSAC and SAC was 20.8% and 5.9%, respectively. The prevalence of any STH, MHI STH, ascariasis, MHI ascariasis, and MHI trichuriasis was significantly higher in PSAC. Stunting, underweight, wasting, overweight/obesity, and anemia prevalence was 38.4%, 24.5%, 4.8%, 2.7%, and 34.7% in PSAC, while the prevalence was 34.3%, 21.6%, 8.7%, 3.0%, and 19.2% in SAC, respectively. Anemia and wasting prevalence were significantly higher in PSAC and SAC, respectively. There were five schistosomiasis cases found (0.8% prevalence), while schistosomiasis seroprevalence was 60.1%. Validated and reported sanitary toilet coverage was significantly different in eight out of 13 barangays. Stunting and anemia were associated with STH. STH and anemia prevalence were significantly higher in non-ZOD barangays. High STH burden in PSAC and SAC persists. A more coordinated response addressing STH, undernutrition, and WASH in disaster-stricken areas will require strengthening local health systems and promoting intersectoral collaboration.

 抽象的

本研究旨在描述：1) 学龄前儿童 (PSAC) 和学龄儿童 (SAC) 中土源性蠕虫病 (STH) 和血吸虫病的患病率和强度，2) SAC 中的血吸虫病血清患病率，3) SAC 中的营养不良患病率，4) 家庭卫生厕所覆盖率，以及 5) STH、日本血吸虫暴露、营养状况和卫生设施之间的关联。采用 Kato–Katz 技术和 ELISA 抗体检测方法对海盐灾区两个省份的 PSAC 和 SAC 进行了检测。还获得了人体测量和血红蛋白测量值。所报告的卫生厕所覆盖率在一项调查中得到了验证。 PSAC 和 SAC 中任何 STH 的患病率分别为 50.2% 和 41.3%。 PSAC 和 SAC 中中重度 (MHI) STH 患病率分别为 20.8% 和 5.9%。 PSAC 中任何 STH、MHI STH、蛔虫病、MHI 蛔虫病和 MHI 鞭虫病的患病率显着较高。 PSAC 中发育迟缓、体重不足、消瘦、超重/肥胖和贫血的患病率分别为 38.4%、24.5%、4.8%、2.7% 和 34.7%，而患病率分别为 34.3%、21.6%、8.7%、3.0% 和 19.2分别占 SAC 的%。 PSAC 和 SAC 的贫血和消瘦患病率分别显着较高。发现血吸虫病病例 5 例（患病率 0.8%），血吸虫病血清阳性率为 60.1%。经验证和报告的卫生厕所覆盖率在 13 个描笼涯中的 8 个中存在显着差异。发育迟缓和贫血与 STH 有关。非 ZOD 描笼涯的 STH 和贫血患病率显着较高。 PSAC 和 SAC 的 STH 负担依然较高。 要在受灾地区采取更加协调一致的应对措施，解决 STH、营养不良和 WASH 问题，需要加强当地卫生系统并促进部门间合作。
