This study aimed to use primary care electronic health records to evaluate the prevalence of overweight and obesity in 2-15-year-old children in England and compare trends over the last two decades.
Cohort study of primary care electronic health records.
375 general practices in England that contribute to the UK Clinical Practice Research Datalink.
Individual participants were sampled if they were aged between 2 and 15 years during the period 1994-2013 and had one or more records of body mass index (BMI).
Prevalence of overweight (including obesity) was defined as a BMI equal to or greater than the 85th centile of the 1990 UK reference population.
Data were analysed for 370 544 children with 507 483 BMI records. From 1994 to 2003, the odds of overweight and obesity increased by 8.1% per year (95% CI 7.2% to 8.9%) compared with 0.4% (-0.2% to 1.1%) from 2004 to 2013. Trends were similar for boys and girls, but differed by age groups, with prevalence stabilising in 2004 to 2013 in the younger (2-10 year) but not older (11-15 year) age group, where rates continued to increase.
Primary care electronic health records in England may provide a valuable resource for monitoring obesity trends. More than a third of UK children are overweight or obese, but the prevalence of overweight and obesity may have stabilised between 2004 and 2013.
本研究旨在利用基层医疗电子健康记录评估英格兰2至15岁儿童超重和肥胖的患病率，并比较过去二十年的趋势。
基层医疗电子健康记录队列研究。
英国375家参与英国临床实践研究数据链的全科诊所。
个体参与者入选标准为1994年至2013年期间年龄在2至15岁之间且有一条或多条体重指数（BMI）记录。
超重（包括肥胖）患病率定义为BMI等于或高于1990年英国参考人群第85百分位数。
对370544名儿童的507483条BMI记录进行了分析。1994年至2003年，超重和肥胖的几率每年增加8.1%（95%可信区间7.2%至8.9%），而2004年至2013年为0.4%（-0.2%至1.1%）。男孩和女孩的趋势相似，但因年龄组而异，2004年至2013年，较年轻（2至10岁）年龄组的患病率趋于稳定，而较年长（11至15岁）年龄组的患病率继续上升。
英格兰基层医疗电子健康记录可能为监测肥胖趋势提供宝贵资源。超过三分之一的英国儿童超重或肥胖，但超重和肥胖的患病率在2004年至2013年期间可能已趋于稳定。
