To describe the epidemiological characters of pregnancy-induced hypertension (PIH) in Jiaxing areas of Zhejiang province of China between 1995 and 2000.
We analyzed the perinatal health surveillance data that was collected as part of the Sino-American cooperative project on neural tube defects prevention established in 1992. The study population consisted of 136 070 pregnant women with at least 20 weeks of gestational age. National diagnostic criteria were used to identify the cases which were divided into three subgroups: mild, moderate and severe.
15 127 cases were identified and the overall incidence rate of PIH was 11.1% (95% CI : 11.0% - 11.3%). Among all the cases, mild, moderate and severe PIH were accounted for 71.4%, 22.3% and 6.3%, respectively. The proportions of PIH cases that occurred in the second trimester, third trimester and during delivery appeared to be 4.2%, 34.4% and 61.4%, respectively. There was a significant fall in the trend of PIH occurrence every year, which dropped from 10.7% in 1995 to 8.6% in 2000 by 19.6%. More risk of PIH seemed to be related to those mothers living in the urban areas with age under 20 or above 35, being peasants and having little educational, having had multiple gestations, conceiving in spring/summer or delivering in winter or spring etc. Compared with the results of national survey in 1988, the incidence rate of PIH was higher by 18.1%, while the proportion of severe PIH was much lower by 68.8%. Although the incidence rates of PIH in urban and rural areas were somehow similar, the proportion of severe PIH in rural areas was much higher than that in urban areas.
Overall incidence rate and distribution of PIH were reported. Compared with the results in 1988, incidence rate of PIH was much higher, particularly for mild cases.
描述1995年至2000年中国浙江省嘉兴地区妊娠高血压综合征（PIH）的流行病学特征。
我们分析了作为1992年中美神经管缺陷预防合作项目一部分收集的围产期健康监测数据。研究人群包括136070名孕周至少20周的孕妇。采用国家诊断标准确定病例，并将其分为三个亚组：轻度、中度和重度。
共确定15127例病例，PIH的总体发病率为11.1%（95%可信区间：11.0% - 11.3%）。在所有病例中，轻度、中度和重度PIH分别占71.4%、22.3%和6.3%。PIH病例发生在孕中期、孕晚期和分娩期的比例分别为4.2%、34.4%和61.4%。PIH的发病趋势每年有显著下降，从1995年的10.7%降至2000年的8.6%，下降了19.6%。PIH的更多风险似乎与居住在城市地区、年龄在20岁以下或35岁以上、为农民且教育程度低、有多次妊娠、在春季/夏季受孕或在冬季或春季分娩等的母亲有关。与1988年全国调查结果相比，PIH的发病率高18.1%，而重度PIH的比例低68.8%。虽然城乡地区PIH的发病率在某种程度上相似，但农村地区重度PIH的比例远高于城市地区。
报告了PIH的总体发病率和分布情况。与1988年的结果相比，PIH的发病率高得多，尤其是轻度病例。
