We conducted a study in a low-ranking socioeconomic community in Yangon, Myanmar (Burma) to determine the source of household faecal contamination (HFC), devise an index, and associate this index with diarrhoeal incidence in children. Observation was used to collect information on the sources of household faecal contamination (HFC) and a twice-weekly monitoring scheme was employed for determining diarrhoea incidence. A valid household faecal contamination index (HFCI) was developed using three sources of HFC: going about without footwear, indiscriminate defaecation near or under the house, and absence of latrine. The risk of diarrhoea significantly increased from 4.21 to 8.66 per 1000 child-days (P less than 0.001) when HFCI increased from 0 to 3. Although the adjusted rate ratios for the three levels of HFCI were approximately equal to 2.00 (2.16, 1.77, 2.14), they were not statistically significant. Further studies are needed to corroborate the results of what seems to be the first study attempting to associate HFC with diarrhoea incidence.
我们在缅甸仰光一个社会经济地位较低的社区开展了一项研究，以确定家庭粪便污染（HFC）的来源、设计一个指数，并将该指数与儿童腹泻发病率相关联。通过观察收集有关家庭粪便污染来源的信息，并采用每周两次的监测方案来确定腹泻发病率。利用家庭粪便污染的三个来源开发了一个有效的家庭粪便污染指数（HFCI）：不穿鞋走动、在房屋附近或下方随意排便以及没有厕所。当HFCI从0增加到3时，腹泻风险从每1000儿童日4.21显著增加到8.66（P小于0.001）。尽管HFCI三个水平的调整率比约等于2.00（2.16、1.77、2.14），但它们在统计学上并不显著。需要进一步的研究来证实这项似乎是首次尝试将HFC与腹泻发病率相关联的研究结果。
