OBJECTIVE We investigated the relationship between drinking water and sub-health of residents in Guangzhou, according to which may provide a reference for the relevant departments to formulating policies. METHODS We designed questionnaire, in which included subhealth and its component factors of residents in Guangzhou, also included those objects＇ general information, drinking water knowledge on health and its awareness and so on, according to the aim and requirements of our research.

There was some statistical differences between drinking water types and subhealth incidence among residents in Guangzhou（P〈0.05）, among which subhealth occurrence rate of residents selected tap water was 85.2%, while the one of those who selected activated water was 55.6%. When we carried statistical analysis on hierarchical sub-health factors of the drinking water types, and scored sub-health factors, we found that no matter what residents chose dringking water, the score of fatigue, especially activities and back fatigue among those factors was highest,this indicated that there was much opportunity to occure sub-health among residents who had more scores of sub-health.
