[Years of potential life of residents among different flood areas in Hunan province].

Objective: To determine the damage of different types of floods on the residents health.

Methods: The methods of standard mortality rate (SMR) and years of potential life lost (YPLL) were used to analyze the death of sample residents from flood areas in Dongting Lake in Hunan province.

Results: The order of death causes in the soaked area, the collapsed area and the non-flood area was the same. But the mortality rates of residents injury, poisoning and malignant neoplasm diseases in the soaked area and the collapsed area were higher than those of non-flood area. The resident standard rates of years of potential life lost (SYPLL) in the soaked area and the collapsed area were higher than that of the controls, especially in the age group of 30 to 45. The flood-attributed SYPLL in the male was higher than that of the female.

Conclusion: Flood actually affected the health of residents. The more serious the flood is, the worse the effect is. It is very important to decrease the resident mortality rate of the injury, poisoning and malignant neoplasm, and to pay attention to protect people of 30 to 45 years old in flood areas.
