To investigate the detection status of hypertensive disorders of pregnancy (HDP) and its impact on maternal and neonatal adverse pregnancy outcomes (APO) among pregnant women in Tacheng prefecture, an underdeveloped region of Xinjiang.

A retrospective analysis was conducted on 1, 534 pregnant women with complete registration records from 4 county-or city-level institutions affiliated with the Tacheng Prefecture Maternal and Child Health Care and Family Planning Service Center between March 2022 and August 2024. The chi-square test was used to compare the differences in the detection rates of maternal and neonatal APO between the HDP and non-HDP groups, and Logistic regression analysis was employed to explore the relationship between HDP and maternal or neonatal APO.

HDP was detected in 117 cases (7.63%). Compared with the non-HDP group, the incidence of APO in the HDP group [37.61%(44/117), 17.71%(251/1 417)] was higher, and the difference was statistically significant (χ²=27.536, P<0.01). The main complications included preterm birth [18.80%(22/117), 6.63%(94/1 417)] and low birth weight [14.53%(17/117), 4.38%(62/1 417)], the differences were statistically significant (χ²=22.898, 22.814, all P<0.05). However, there was no statistically significant difference in the incidence of APO between the two groups of mothers [13.68%(16/117), 11.93%(169/1 417)]. Multivariate Logistic regression analysis showed that after adjusting for the pregnant woman′s age, ethnicity, body mass index, parity, and the number of singleton or twin pregnancies, HDP was an independent risk factor for perinatal APO [OR=2.263(95%CI: 1.497-3.420), P<0.001], preterm birth [OR=2.598(95%CI: 1.522-4.434), P=<0.001], and low birth weight [OR=3.061(95%CI: 1.663-5.636), P<0.001].

The detection rate of HDP among pregnant women in the Tacheng prefecture of Xinjiang is 7.63%, and HDP is associated with perinatal APO, including preterm birth and low birth weight.
