This study analyzed the epidemiological characteristics of endometriosis among rural women in Yantai City, Shandong Province, during 2007. Researchers utilized stratified sampling to survey 7832 women over the age of 18, achieving a high response rate with 7798 valid questionnaires. The results indicated a prevalence rate of 4.72%, with significantly higher rates observed in women aged 25 to 45 and those engaged in mental labor compared to manual laborers. This paper is centrally about endometriosis — specifically its epidemiological distribution and risk factors within a rural Chinese population.
