目的 了解儿童血压水平及高血压的发生状况 ,初步探索儿童原发性高血压的易患因素。方法 用整群抽样的方法对北票市城乡 7～ 14岁儿童 5 76 2名进行血压测量 ,将发现的所有高血压者作为病例组 ,用随机抽样的方法在所有正常儿童中选择对照组 ,进行 1∶1病例对照配对。所有儿童均填写统一制定的调查表 ,并做血常规检查 ,包括 18项血液学指标。采用SPSS 10 0软件进行有关的统计分析。结果 单因素分析显示 :体质指数 (BMI)升高是儿童高血压的重要危险因素。将收缩压 (SBP)和舒张压 (DBP)分别进行分析 ,发现BMI、月经初潮、白细胞 (WBC)、淋巴细胞计数 (LYM)、单核细胞百分比 (MON % )、单核细胞计数 (MON)与是收缩期高血压的危险因素 ;BMI也是舒张期高血压的危险因素。多因素Logistic回归分析显示 :BMI是儿童高血压发病的危险因素。收缩期高血压发病的危险因素有BMI、WBC、MON % ;舒张期高血压发病的危险因素有BMI。结论 肥胖是儿童高血压的重要危险因素 ,与收缩期及舒张期高血压均有关系。WBC和MON %的升高是收缩期高血压的危险因素。
Objective To understand the prevalence of hypertension and blood pressure in children and to explore the predisposing factors of essential hypertension in children. Methods A total of 5 762 children aged 7-14 years in urban and rural areas of Beipiao city were measured by cluster sampling method. All the patients with hypertension were selected as the case group. The control group was selected from all the normal children by random sampling. A 1: 1 case-control paired. All children completed a uniformly developed questionnaire and performed routine blood tests, including 18 hematology indicators. Use SPSS 10 0 software for statistical analysis. Results Univariate analysis showed that elevated body mass index (BMI) was an important risk factor for hypertension in children. BMI, menarche, white blood cell (WBC), lymphocyte count (LYM), monocyte percentage (MON%), monocyte count (MON) were measured by analyzing systolic blood pressure (SBP) and diastolic blood pressure (DBP) And is a risk factor for systolic hypertension; BMI is also a risk factor for diastolic hypertension. Multivariate Logistic regression analysis showed that: BMI is a risk factor for the incidence of hypertension in children. Risk factors for systolic hypertension have BMI, WBC, MON%; diastolic hypertension risk factors BMI. Conclusion Obesity is an important risk factor for children with hypertension, and systolic and diastolic hypertension are related. Elevated WBC and MON% are risk factors for systolic hypertension.
