To investigate the correlations between occupational risk factors and reproductive health and to provide targeted healthcare services to female civil aviation employees based on surveys about menstrual and reproductive health status.Subjects were selected from flight attendants working for China Southern Airlines, Air China, and other airlines; employees of China Aviation Oil Limited, China TravelSky, and China Aviation Supplies Holding Company; and airport ground service crews. Data were collected using anonymous questionnaires. A total of 1175 valid questionnaires were recovered. The subjects were categorized into a flight attendant group and a ground service group, which contained 563 and 612 women, respectively.The prevalence of irregular menstruation, including abnormal cycles, severe dysmenorrhea, and hypomenorrhea or menorrhagia, was significantly higher in the flight attendant group (30.55%) than in the ground service group (13.40%); in concordance, the fertility rate was significantly lower in the flight attendant group (36.59%) than in the ground service group (43.95%). The spontaneous abortion rate in the flight attendant group (6.80%) was significantly higher than in the ground service group (2.97%). The rate of life-threatening abortions, preterm births, and low birth weight was significantly lower in the flight attendant group than in the ground service group.The impact of occupational risk factors on the reproductive health of female aviation workers should be evaluated and examined more thoroughly. Additional healthcare services such as routine menstruation healthcare and policies for workers planning to have a pregnancy are beneficial in monitoring reproductive health, reducing harmful exposures during early pregnancy, and preventing incapacitating gynecologic events.
