Priti Bandi, Ph.D., from the American Cancer Society in Atlanta, and colleagues compared the prevalence of major modifiable cancer risk factors, human papillomavirus (HPV) vaccination, and screenings among U.S. adults during and after COVID-19 versus before the pandemic.

美国亚特兰大癌症协会的Priti Bandi博士及其同事比较了新冠疫情期间和之后与疫情前美国成年人主要可改变的癌症风险因素、人乳头瘤病毒（HPV）疫苗接种率以及筛查率的变化。

The researchers observed a decrease in the prevalence of smoking, from 14.2 percent in 2019 to 11 percent in 2023; higher prevalence persisted among American Indian/Alaska Native individuals, Black men, lower-educated individuals, and bisexual women. Between 2017 to March 2020 and August 2021 to August 2023, the prevalence of excess body weight remained stable (overweight, 31.8 percent; obesity, 40.4 percent).

研究人员观察到吸烟率从 2019 年的 14.2% 下降到 2023 年的 11%；美洲印第安人/阿拉斯加原住民、黑人男性、受教育程度较低的人群和双性恋女性中仍然存在较高的吸烟率。2017 年至 2020 年 3 月以及 2021 年 8 月至 2023 年 8 月期间，超重人群的比率保持稳定（超重者为 31.8%，肥胖者为 40.4%）。

More than half (51.5 percent) of adults reported not meeting recommended aerobic activity levels, and 6.4 percent reported heavy alcohol use, with no change from 2020 to 2022. Up-to-date HPV vaccination prevalence was unchanged between 2021 and 2023 (61.4 percent in those aged 13 to 17 years) compared with a previously increasing trend.

超过一半（51.5%）的成年人报告称未达到推荐的有氧活动水平，6.4%报告称有重度饮酒行为，2020年至2022年间无变化。2021年至2023年期间，最新的HPV疫苗接种率保持不变（13至17岁人群为61.4%），而此前接种率呈现上升趋势。

U.S Preventive Services Task Force recommendation-concordant prevalence of screening increased for breast and colorectal cancer from 2019 to 2023 (79.9 and 60.4 percent, respectively), rebounding from declines or stable trends noted during 2019 to 2021..

从2019年到2023年，美国预防服务工作组推荐的乳腺癌和结直肠癌筛查率分别上升至79.9%和60.4%，扭转了2019年至2021年间观察到的下降或稳定趋势。

'Despite historic reductions in smoking levels and improvement in breast and colorectal cancer screenings, including following the COVID-19 pandemic, obesity rates remain high and unchanged, physical activity levels remain suboptimal, and HPV vaccination levels have plateaued since 2021,' the authors write..

“尽管吸烟水平的历史性下降以及乳腺癌和结直肠癌筛查的改善，包括在新冠疫情之后，但肥胖率仍然居高不下且未见变化，身体活动水平仍然不理想，HPV疫苗接种水平自2021年以来已趋于停滞，”作者写道。
