Vital Signs: Colorectal Cancer Screening Test Use — United States, 2018
バイタルサイン:大腸癌スクリーニング検査の利用 ― アメリカ、2018年
2018年のBehavioral Risk Factor Surveillance Systemの調査データから、アメリカの50~75歳の成人における大腸癌(CRC)のスクリーニング検査率が分析された。2018年における検査率は68.8%で、年齢別では50~54歳にてもっとも低く(50.0%)、年齢とともに有意に増加し(p<0.005)、70~75歳では81.3%であり、全体を50~64歳と65~75歳に分けた場合、それぞれ63.3%、79.2%であった。50~64歳では女性(65.4%、男性61.1%)、医療保険加入者(66.7%、未加入者32.6%)、かかりつけ医がいる人(68.1%、いない人32.7%)、大都市圏居住者(68.1%、非大都市圏64.4%)にて検査率が高く、また、世帯年収、学歴が高いほど高かった(年間世帯年収$75,000以上:70.8%、大卒:70.7%)。65~75歳でも同様に女性(80.1%、男性:78.2%)、医療保険加入者(79.7%、未加入者:55.7%)、かかりつけ医がいる人(81.6%、いない人:45.6%)、大都市圏居住者(80.2%、非大都市圏:77.6%)にて高く、世帯年収および学歴の高いほど高かった(世帯年収$75,000以上:87.1%、大卒:85.0%)。州別ではマサチューセッツ州にて全体、64~75歳ともにもっとも高く(各76.5%、72.1%)、ワイオミング州にてともにもっとも低かった(各57.8%、51.5%)。65~75歳はロードアイランド州にてもっとも高く(84.9%)、ワイオミング州にてもっとも低かった(68.5%)。また、50~64歳では70.5%以上の州が4州、60%未満の州が11州、65~75歳では49州およびワシントンDCで70.5%以上であった。以上、CRCのスクリーニング検査率は50~64歳では65~75歳に比べて15.9パーセントポイント低く、今後は、50歳から75歳までの人に対し、CRCのスクリーニング検査を推奨する必要性が示唆された。
