title: [Effect of health service and its influence factors in flood disaster areas].
abstract: OBJECTIVE
  To explore the effect of health service and its influential factors in flood disaster areas.
  
  
  METHODS
  Fifty-five towns were sampled randomly from Dongting Lake area suffering from flood in 1998. The health service level, effect, and its influence factors were investigated retrospectively.
  
  
  RESULTS
  The incidence rate of notifiable infectious diseases was 11.7 per thousand, prevalence rate of chronic disease was 51.2 per thousand, infant mortality rate was 43.1 per thousand, neonatal mortality rate was 10.2 per thousand, and the total mortality rate was 554.3/100,000 in Dongting Lake area. The health investment level was significantly associated with the incidence rate of notifiable infectious diseases, the infant mortality rate, and total mortality rate. Duration of flood and income per capita were important factors for the effect of health investment.
  
  
  CONCLUSIONS
  Increasing health investment and residents' income in the flood disaster area, shortening the duration of flood would play positive role in residents' health in the flood disaster area.
