In 2011, the National Health Interview Survey (NHIS), an in-person household interview, revised the human immunodeficiency virus (HIV) section of the survey and the Behavioral Risk Factor Surveillance System (BRFSS), a telephone-based survey, added cellphone numbers to its sampling frame. We sought to determine how these changes might affect assessment of HIV testing trends.
We used linear regression with pairwise contrasts with 2003-2013 data from NHIS and BRFSS to compare percentages of persons aged 18-64 years who reported HIV testing in landline versus cellphone-only households before and after 2011, when NHIS revised its in-person questionnaire and BRFSS added cellphone numbers to its telephone-based sample.
In NHIS, the percentage of persons in cellphone-only households increased 13-fold from 2003 to 2013. The percentage ever tested for HIV was 6%-10% higher among persons in cellphone-only than landline households. The percentage ever tested for HIV increased significantly from 40.2% in 2003 to 45.0% in 2010, but was significantly lower in 2011 (40.6%) and 2012 (39.7%). In BRFSS, the percentage ever tested decreased significantly from 45.9% in 2003 to 40.2% in 2010, but increased to 42.9% in 2011 and 43.5% in 2013.
HIV testing estimates were lower after NHIS questionnaire changes but higher after BRFSS methodology changes. Data before and after 2011 are not comparable, complicating assessment of trends.
2011年，全国健康访谈调查（NHIS，一项面对面的家庭访谈）修订了调查中的人类免疫缺陷病毒（HIV）部分，而行为危险因素监测系统（BRFSS，一项基于电话的调查）在其抽样框架中增加了手机号码。我们试图确定这些变化如何影响HIV检测趋势的评估。
我们使用线性回归及成对对比，分析2003 - 2013年NHIS和BRFSS的数据，以比较2011年前后18 - 64岁人群中报告进行过HIV检测的比例，2011年NHIS修订了其面对面调查问卷，BRFSS在其基于电话的样本中增加了手机号码。
在NHIS中，仅使用手机的家庭中的人口比例从2003年到2013年增加了13倍。仅使用手机的家庭中接受过HIV检测的人口比例比使用固定电话的家庭高6% - 10%。接受过HIV检测的人口比例从2003年的40.2%显著增加到2010年的45.0%，但在2011年（40.6%）和2012年（39.7%）显著降低。在BRFSS中，接受过检测的人口比例从2003年的45.9%显著下降到2010年的40.2%，但在2011年增加到42.9%，在2013年增加到43.5%。
NHIS问卷更改后HIV检测估计值较低，但BRFSS方法更改后较高。2011年前后的数据不可比，这使得趋势评估变得复杂。
