Data were analyzed using meta-analysis (random effects model) by STATA Ver.11 software. Heterogeneity of studies was assessed using I2 index. The GHQ-28 questionnaire was used in all studies. In 79 reviewed studies with a sample of 31765 people during the years 1999 to 2015, good general health in Iran was 50% (95% CI, 42%-58%), 40% of individuals had poor general health and 30% of individuals had fairly acceptable public health. Also, poor general health was 47% among women and 36% among men. A significant percentage of Iranians suffer from poor general health. Hence, noticing the state of public health and providing the basis for the realization of a dynamic and healthy life for community members seems essential.
