日本血吸虫病是一种慢性蠕虫感染，通过接触日本血吸虫感染的水而感染。感染与严重的疾病，是一个重要的公共卫生问题在Philippines. OBJECTIVE估计协议的频率之间的水接触双月访谈，自我管理的日记和observations.METHODS共286个人进行了为期4个月或6个月的时间。直接观察和两个双月和日记的方法之间的协议estimated.RESULTS观察和双月访谈之间的协议是71.8%时，没有任何水接触被认为是，但下降到23.3%时，只有天至少有一些水接触被认为是。观察和日记之间的协议是78.7%时，没有任何水接触的日子被认为是40.8%时，只有天与一些水接触considered.CONCLUSIONS协议的水接触的程度是不同的测量工具之间的差。这对未来的研究具有重要意义，因为高度的测量误差会严重影响涉及水接触的研究结果。
BACKGROUND 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.OBJECT To estimate the agreement in the frequency of water contact between bimonthly interviews, self-administered diaries and observations.METHODS 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.RESULTS 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.CONCLUSIONS 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.
