Objective: To analyze the average systolic blood pressure (SBP) and diastolic blood pressure (DBP) among adults aged 18 years old and above in China between 2010 and 2012; and to compare the difference in the results measured by mercury sphygmomanometer and converted electronic sphygmomanometer. Methods: The data was collected from Chinese Nutrition and Health Surveillance in 2010-2012. 120 428 adults aged 18 years old and above were selected from 150 survey counties (districts) of 31 provinces in China Mainland, by multi-stage stratified and probability proportion to size (PPS) cluster randomization sampling method. The average blood pressure value was calculated from three systolic and diastolic blood pressure readings measured by mercury sphygmomanometer. The value of Electronic Sphygmomanometer was converted by regression formula. Age-standardized results were calculated incorporating a complex sample weighting using the population data from the National Bureau of Statistics in 2009. Results: The overall adjusted mean of SBP based on the value of mercury sphygmomanometer among Chinese adults aged 18 years old and above was 122 mmHg (1 mmHg=0.133 kPa), 124 mmHg in men and 120 mmHg in women. The average SBP value was separately 115, 127, and 137 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average SBP was 122 mmHg in urban and 122 mmHg in rural areas. Mean DBP was 78 mmHg, 79 mmHg in men and 76 mmHg in women. The average DBP was separately 75, 81, and 81 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average DBP was 78 mmHg in urban and 77 mmHg in rural areas. The overall adjusted mean of SBP based on converted electronic device was 129 mmHg,130 mmHg in men and 127 mmHg in women, respectively. The mean of SBP was separately122, 134, and 143 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. Mean SBP was both 129 mmHg in urban and in rural areas. Mean DBP was 76 mmHg, 78 mmHg in men and 75 mmHg in women, respectively. The average DBP was separately 74, 79, and 79 mmHg in groups of adults aging 18-44, 45-59 and ≥60 years old. The average DBP was both 76 mmHg in urban and rural areas. Conclusion: The average SBP and DBP was different between the mercury sphygmomanometer and converted electronic device. However, the results from both measures showed that the blood pressure was higher in men than in women, the blood pressure increased with the increase of age, and there was no difference between urban and rural areas.
目的： 分析2010—2012年中国18岁及以上成年居民血压水平，比较汞柱式血压值和转换电子血压值的差别。 方法： 2010—2012年中国居民营养与健康状况监测采用多阶段分层与人口成比例整群随机抽样方法，调查对象为中国内地31个省份、150个调查县（区）的18岁及以上成年人120 428名。采用汞柱式血压计测量血压，取3次的平均值；利用回归公式转换成电子血压值，采用2009年国家统计局人口数据对血压值进行复杂抽样加权处理。 结果： 经复杂抽样加权处理后，由汞柱式血压值得到中国18岁及以上成年人平均SBP为122 mmHg（1 mmHg=0.133 kPa），男性为124 mmHg，女性为120 mmHg；18~44、45~59和60岁及以上人群的平均SBP分别为115、127和137 mmHg；城市、农村分别为122和122 mmHg。成年人平均DBP为78 mmHg，男性为79 mmHg，女性为76 mmHg；18~44、45~59和60岁及以上人群的平均DBP分别为75、81和81 mmHg；城市为78 mmHg，农村为77 mmHg。按回归方程转换为电子血压值后，得到中国成年人平均SBP为129 mmHg，男性为130 mmHg，女性为127 mmHg；18~44、45~59和60岁及以上人群的平均SBP分别为122、134和143 mmHg；城市、农村均为129 mmHg。成年人平均DBP为76 mmHg，男性为78 mmHg，女性为75 mmHg；18~44、45~59和60岁及以上人群的平均DBP分别为74、79和79 mmHg；城市、农村均为76和76 mmHg。 结论： 实测汞柱血压值和转换电子血压值不同，后者的结果均偏高；但两种数值计算的血压水平具有相似特点，男性高于女性，随年龄增长而增高，城乡没有差别。.
