背景:通常通过自我报告来评估心脑血管危险因素的存在。然而,在老龄化研究中,自我报告的心脑血管危险因素的信度和效度仍然不一致.
目的:为了确定最常见的自我报告的血管危险因素的信度和效度:高血压,糖尿病,还有心脏病.
方法:1,870名65岁或以上的非裔美国人,加勒比海西班牙裔,和非西班牙裔白人个体被招募作为衰老和痴呆的社区研究的一部分.我们评估了可靠性,有效性,灵敏度,特异性,和自我报告的高血压的百分比一致性,糖尿病,还有心脏病,与直接测量血压相比,血红蛋白A1c(HbA1c),和药物使用。分析随后按年龄分层,性别,教育,和种族群体。
结果:高血压自我报告的可靠性,糖尿病,心脏病非常好。自我报告和临床措施之间的协议是中等的高血压(kappa:0.58),对糖尿病有好处(卡帕:0.76-0.79),中度心脏病(卡帕:0.45)因年龄而异,性别,教育,和种族群体。对高血压的敏感性和特异性为88.6%-78.1%,糖尿病患者为87.7%-92.0%(HbA1c≥6.5%)或92.7%-92.8%(HbA1c≥7%),心脏病的发生率为85.8%-75.5%。对于高血压,自我报告的一致性百分比为87.0%,91.6%-92.6%为糖尿病患者,心脏病占77.4%。
结论:确定自我报告的高血压病史,糖尿病,与直接测量或药物使用相比,心脏病是可靠和有效的。
Queries for the presence of cardiovascular and cerebrovascular risk factors are typically assessed through self-report. However, the reliability and validity of self-reported cardiovascular and cerebrovascular risk factors remain inconsistent in aging research.
To determine the reliability and validity of the most frequently self-reported vascular risk factors: hypertension, diabetes, and heart disease.
1,870 individuals aged 65 years or older among African Americans, Caribbean Hispanics, and white non-Hispanic individuals were recruited as part of a community
study of aging and dementia. We assessed the reliability, validity, sensitivity, specificity, and percent agreement of self-reported hypertension, diabetes, and heart disease, in comparison with direct measures of blood pressure, hemoglobin A1c (HbA1c), and medication use. The analyses were subsequently stratified by age, sex, education, and ethnic group.
Reliability of self-reported hypertension, diabetes, and heart disease was excellent. Agreement between self-reports and clinical measures was moderate for hypertension (kappa: 0.58), good for diabetes (kappa: 0.76-0.79), and moderate for heart disease (kappa: 0.45) differing slightly by age, sex, education, and ethnic group. Sensitivity and specificity for hypertension was 88.6% -78.1%, for diabetes was 87.7% -92.0% (HbA1c ≥6.5%) or 92.7% -92.8% (HbA1c ≥7%), and for heart disease was 85.8% -75.5%. Percent agreement of self-reported was 87.0% for hypertension, 91.6% -92.6% for diabetes, and 77.4% for heart disease.
Ascertainment of self-reported histories of hypertension, diabetes, and heart disease are reliable and valid compared to direct measurements or medication use.
