Most national-level mammography data are for ever-had and most-recent screening. There are few national-level data on rates of repeat, on-schedule mammography, and on the prevalence and correlates of repeat mammography. It is also important to investigate the similarity of correlates for repeat and recent mammography.
Analyses were from data for women ages 45 to 75 in the 2002 to 2003 Health Information and National Trends Survey (HINTS 2003; N = 1,581). The two dependent variables were self-report of repeat mammography (two exams on schedule, based on an every-other-year interval) and recent mammography only (one mammogram within the past 2 years).
The prevalence of recent mammography was 81.6% (95% confidence interval, 79.1-84.1) and for repeat mammography was 72.2% (95% confidence interval, 69.0-75.4). An access to care variable combining insurance coverage and regular source of care was the strongest sociodemographic correlate of both mammography indicators. Most other sociodemographic variables were not associated with mammography status. Five psychosocial/behavioral variables were associated with both mammography indicators (smoking status, attention to health information, knowledge of screening interval, worry about breast cancer, and recent mood status). Correlates were very similar for repeat and recent mammography.
Although access to care had the strongest association with mammography, psychosocial and behavioral variables did better as a group than the sociodemographic variables. A standard set of such variables should be considered for all national surveys.
大多数国家级乳腺钼靶检查数据是关于曾经接受过检查和最近一次筛查的情况。关于重复检查、按时进行乳腺钼靶检查的比率，以及重复乳腺钼靶检查的患病率及其相关因素的国家级数据很少。研究重复乳腺钼靶检查和最近一次乳腺钼靶检查相关因素的相似性也很重要。
分析的数据来自2002年至2003年健康信息与国家趋势调查（HINTS 2003；N = 1581）中45至75岁女性的数据。两个因变量分别是重复乳腺钼靶检查的自我报告（按照每隔一年的间隔安排进行两次检查）和仅最近一次乳腺钼靶检查（过去两年内进行过一次钼靶检查）。
最近一次乳腺钼靶检查的患病率为81.6%（95%置信区间，79.1 - 84.1），重复乳腺钼靶检查的患病率为72.2%（95%置信区间，69.0 - 75.4）。一个综合保险覆盖范围和常规医疗来源的医疗可及性变量是这两个乳腺钼靶检查指标最强的社会人口统计学相关因素。大多数其他社会人口统计学变量与乳腺钼靶检查状态无关。五个心理社会/行为变量与这两个乳腺钼靶检查指标都相关（吸烟状况、对健康信息的关注、对筛查间隔的了解、对乳腺癌的担忧以及近期情绪状态）。重复乳腺钼靶检查和最近一次乳腺钼靶检查的相关因素非常相似。
虽然医疗可及性与乳腺钼靶检查的关联最强，但心理社会和行为变量作为一个整体比社会人口统计学变量表现更好。所有国家调查都应考虑一套标准的此类变量。
