Nondaily intermittent smokers (ITS) are common, but their cessation behavior remains elusive. We examined cessation of native-ITS (n = 2040), converted-ITS (n = 1808), and daily smokers (DS; n = 25 344). All ITS were more likely than were DS to make a quit attempt (native-ITS adjusted odds ratio [AOR] = 1.60, 95% confidence interval [CI] = 1.42, 1.80; converted-ITS AOR = 3.33, 95% CI = 2.93, 3.78). Native-ITS (18%) and converted-ITS (27%) were more likely than were DS (13%) to quit smoking (native-ITS AOR = 1.34, 95% CI = 1.07, 1.67; converted-ITS AOR = 2.36, 95% CI = 2.01, 2.78), but the low cessation rates of ITS challenge their nonaddicted status.
非每日间歇性吸烟者（ITS）很常见，但他们的戒烟行为仍然难以捉摸。我们研究了本土 ITS（n=2040）、转换型 ITS（n=1808）和每日吸烟者（DS；n=25344）的戒烟行为。与 DS 相比，所有 ITS 更有可能尝试戒烟（本土 ITS 调整后的优势比 [AOR]=1.60，95%置信区间 [CI]=1.42，1.80；转换型 ITS AOR=3.33，95%CI=2.93，3.78）。与 DS（13%）相比，本土 ITS（18%）和转换型 ITS（27%）更有可能戒烟（本土 ITS AOR=1.34，95%CI=1.07，1.67；转换型 ITS AOR=2.36，95%CI=2.01，2.78），但 ITS 的低戒烟率对他们的非成瘾状态提出了挑战。
