Objective: To investigate the cumulative incidence of severe preeclampsia in Ganzi plateau area, and to analyze its influencing factors. Methods: Data collection and questionnaire survey were performed on pregnant women who underwent physical examination in Ganzi plateau area from January 2020 to June 2021. The cumulative incidence and the influencing factors were analyzed. Results: A total of 150 of the 3 443 pregnant women were diagnosed with severe preeclampsia, and the cumulative incidence rate was 4.36%. The 150 pregnant women with severe preeclampsia were taken as the case group, meantime, 116 healthy pregnant women with physical examination were taken as the control group. The results showed that the age, educational level, more than 3 000 m altitude residence, irregular maternity inspection, Tibetan and other factors were statistically significant between the two groups(P<0.05), however, there were no significant differences in gestational week, menstrual status, occupation, and prenatal education for expectant mothers and other factors(P>0.05). Over 35 years old, high school education or below, more than 3 000 m altitude residence, irregular maternity inspection and Tibetan were factors affecting the prevalence of severe preeclampsia(P<0.05). Conclusion: The cumulative incidence of severe preeclampsia in Ganzi plateau area is 4.36%. Over 35 years old, high school education or below, more than 3 000 m altitude residence, irregular maternity inspection and Tibetan are factors affecting the disease. It is recommended to strengthen pregnancy monitoring to prevent the occurrence of severe preeclampsia, so as to improve health status of pregnant women. |
