Schistosomiasis japonica is a chronic helminthic infection contracted through contact with water infested with Schistosoma japonicum. The infection is associated with severe disease and is an important public health concern in Philippines.
To estimate the agreement in the frequency of water contact between bimonthly interviews, self-administered diaries and observations.
A total of 286 individuals were followed over either a 4 or a 6 months period. Agreement between direct observation and both the bimonthly and diary methods were estimated.
The agreement between the observation and the bimonthly interview was 71.8% when days without any water contacts were considered, but decreased to 23.3% when only days with at least some water contact were considered. The agreement between the observation and the diary was 78.7% when days without any water contacts were considered and 40.8% when only days with some water contacts were considered.
Agreement about the degree of water contact is poor between the different measurement tools. This has important implications for future research, since a high degree of measurement error can severely bias any results from studies involving water contact.
日本血吸虫病是一种通过接触受日本血吸虫污染的水而感染的慢性蠕虫感染。这种感染与严重疾病相关，是菲律宾一个重要的公共卫生问题。
评估双月访谈、自我记录日记和观察法在水接触频率方面的一致性。
在4个月或6个月的时间里对总共286人进行跟踪。评估直接观察法与双月访谈法和日记法之间的一致性。
当考虑无任何水接触的天数时，观察法与双月访谈法之间的一致性为71.8%，但当仅考虑至少有一些水接触的天数时，一致性降至23.3%。当考虑无任何水接触的天数时，观察法与日记法之间的一致性为78.7%，当仅考虑有一些水接触的天数时，一致性为40.8%。
不同测量工具在水接触程度方面的一致性较差。这对未来的研究具有重要意义，因为高度的测量误差可能会严重影响任何涉及水接触研究的结果。
