Chronic infection over a 16-month period and stunting of preschool children were compared between more spatially dense versus dispersed households in rural Panamá. Chronic protozoan infection was associated with higher household density, lower household wealth index, poor household water quality, yard defecation, and the practice of not washing hands with soap before eating. Models for chronic diarrhea confirmed the importance of household wealth, water quality, sanitation, and hygiene practices. Furthermore, chronic protozoan infection was an important predictor for low height-for-age, along with low household wealth index scores, but not household density. Thus, despite better access to health related infrastructure in the more densely populated households, chronic protozoan infection was more common, and was associated with higher rates of child stunting, compared with more dispersed households.
在巴拿马农村，比较了空间密集型家庭和分散型家庭之间 16 个月的慢性感染和学龄前儿童发育迟缓情况。慢性原生动物感染与较高的家庭密度、较低的家庭财富指数、较差的家庭水质、在院子里排便以及饭前不洗手的习惯有关。慢性腹泻模型证实了家庭财富、水质、卫生和卫生习惯的重要性。此外，慢性原生动物感染是身高年龄偏低的一个重要预测因素，与家庭财富指数得分低有关，但与家庭密度无关。因此，尽管人口密集型家庭更容易获得与健康相关的基础设施，但与分散型家庭相比，慢性原生动物感染更为普遍，且与更高的儿童发育迟缓率有关。
