To analyse cervical screening coverage data by age over time in a number of developed countries throughout the world, with specific emphasis on trends for younger women and on age differentials between younger and older women.
Routinely collected cervical screening statistics and survey data were collected on the proportion of women who have undergone cervical screening with cytology in seven countries in the period 1995 to 2005.
Data for the 25-29 age group were examined. Coverage fell in most countries, in three by more than 5 percentage points. In two countries while overall coverage rose in the period, the rise was not as steep in the youngest group of women. Data for each available 5-year age group for the different countries shows a similar gradient in most, regardless of the absolute level of coverage. Although the trend is not uniform in every country, it appears that generally the gap between coverage of younger women and coverage of older women increased, sometimes dramatically, between the mid-1990s and the mid-2000s.
There is a general trend in developed countries towards lower coverage in young women (25-29 years old). No common underlying cause has been clearly identified and there is a need for further studies to investigate the possible reasons for this phenomenon.
分析世界上一些发达国家随时间推移的按年龄分组的宫颈筛查覆盖数据，重点关注年轻女性的趋势以及年轻女性和老年女性之间的年龄差异。
收集了 7 个国家在 1995 年至 2005 年期间接受细胞学宫颈筛查的女性比例的常规收集的宫颈筛查统计数据和调查数据。
检查了 25-29 岁年龄组的数据。大多数国家的覆盖率都有所下降，有 3 个国家下降了 5 个百分点以上。在 2 个国家，虽然该期间的总体覆盖率有所上升，但在最年轻的女性群体中，上升幅度并不那么陡峭。每个国家的每个可用的 5 年年龄组的数据都显示出类似的梯度，这在很大程度上与覆盖率的绝对水平无关。尽管在每个国家的趋势并不统一，但似乎普遍情况是，年轻女性和老年女性之间的覆盖率差距在 20 世纪 90 年代中期到 21 世纪中期之间有所扩大，有时甚至是急剧扩大。
在发达国家，年轻女性（25-29 岁）的覆盖率普遍呈下降趋势。尚未明确确定共同的潜在原因，需要进一步研究以探讨这种现象的可能原因。
