This study aims to analyse changes in the prevalence of cervical cancer (CCa) and breast cancer (BCa) screening among women in the Brazilian capitals and Federal District in the last decade (2007-16).
Data from the surveillance system of risk and protective factors for chronic diseases through telephone interviews (n = 267 949) were used. Adequate screening consisted of, at least, one Pap test triennially, for women aged between 25 and 64 years, and mammography exam biannually, for women aged between 50 and 69 years. The prevalence of adequate screening was investigated for each type of cancer isolated and combined (women aged between 50 and 64 years). The prevalence of adequate screening was estimated for the total population and according to socioeconomic variables. Linear regression models were used.
The prevalence of adequate screening test for CCa remained stable, around 82%, while the screening test for BCa increased from 71 to 78% between 2007 and 2016. Higher increases were observed among women with low schooling and from less developed regions. The percentage of adequate screening (considering both types), for women aged between 25 and 69 years, remained stable, close to 78%.
Screening for BCa increased significantly. Smaller coverage rates are verified among women with low schooling and from less developed regions.
本研究旨在分析过去十年（2007-16 年）巴西各州和联邦区女性宫颈癌（CCa）和乳腺癌（BCa）筛查的流行率变化。
使用通过电话访谈进行的慢性病风险和保护因素监测系统的数据（n=267949）。适当的筛查包括至少每三年进行一次巴氏涂片检查（25-64 岁女性），每两年进行一次乳房 X 光检查（50-69 岁女性）。分别调查了每种癌症（50-64 岁女性）和联合癌症（50-64 岁女性）的适当筛查率。根据社会经济变量，对总人群和特定人群进行了适当筛查率的估计。使用线性回归模型。
CCa 适当筛查试验的流行率保持稳定，约为 82%，而 BCa 筛查试验的流行率从 2007 年到 2016 年从 71%增加到 78%。在受教育程度较低和欠发达地区的女性中，增幅更大。25-69 岁女性的适当筛查率（考虑两种类型）保持稳定，接近 78%。
BCa 的筛查显著增加。受教育程度较低和欠发达地区的女性覆盖率较低。
