Status of birth weight and its correlation with blood pressure in Chongqing urban school-aged children

目的分析重庆市学龄儿童出生体重及与血压的相关关系,为新生儿保健及儿童期高血压预防提供参考。方法采用多阶段抽样方法,于2014年5-6月抽取重庆市两城区3 561名儿童作为研究对象,测量身高、体重、血压等。通过父母自填问卷获得儿童出生体重和高血压家族史等信息。采用描述性分析、χ2分析、Pearson相关分析等对出生体重及与血压的相关关系进行分析。结果 3 561名调查对象平均出生体重为(3.321±0.487)kg。低出生体重儿童166名,发生率为4.7%。高出生体重儿童249名,发生率为7.0%。经相关分析得出,出生体重与收缩压(SBP)、舒张压(DBP)均呈正相关(P<0.05)。结论出生体重是影响儿童血压一个因素,应广泛开展此类研究,为儿童高血压的早期预防提供参考。
