A large proportion of smokers erroneously believe that low-nicotine/low-tar cigarettes, also called "light cigarettes" or "lights," reduce health risks and are a rational alternative to smoking cessation. However, the availability of light cigarettes may deter smoking cessation.
We analyzed the 32374 responses to the US 2000 National Health Interview Survey. Current and former smokers ("ever-smokers") were asked if they had ever used a lower tar and nicotine cigarette to reduce health risks. Multivariable logistic regression identified determinants of lights use and smoking cessation. Results were weighted to reflect the national population.
Of 12285 ever-smokers, 37% (N=4414) reported having used light cigarettes to reduce health risks. Current abstinence was less often reported by ever-smokers who had previously used light cigarettes than by ever-smokers who had never used lights (37% vs 53%, P<.01). Adjusted odds of cessation among ever-smokers who had used light cigarettes relative to those who had never used lights were reduced by 54% (adjusted odds ratio=0.46, 95% confidence interval=0.41, 0.51).
Use of light cigarettes was common and was associated with lower odds of current smoking cessation, validating the concern that smokers may use lights as an alternative to cessation.
很大一部分吸烟者错误地认为，低尼古丁/低焦油香烟，也被称为“淡味香烟”或“轻型香烟”，能降低健康风险，是戒烟的合理替代选择。然而，淡味香烟的可得性可能会阻碍戒烟。
我们分析了对美国2000年国民健康访谈调查的32374份回复。现吸烟者和曾经吸烟者（“曾经吸烟者”）被问及他们是否曾使用焦油和尼古丁含量较低的香烟以降低健康风险。多变量逻辑回归确定了使用淡味香烟和戒烟的决定因素。结果经过加权以反映全国人口情况。
在12285名曾经吸烟者中，37%（N = 4414）报告曾使用淡味香烟以降低健康风险。曾经使用过淡味香烟的曾经吸烟者报告目前已戒烟的比例低于从未使用过淡味香烟的曾经吸烟者（37%对53%，P <.01）。相对于从未使用过淡味香烟的曾经吸烟者，使用过淡味香烟的曾经吸烟者戒烟的调整后几率降低了54%（调整后的优势比 = 0.46，95%置信区间 = 0.41，0.51）。
使用淡味香烟的情况很常见，且与目前戒烟几率较低相关，这证实了人们对于吸烟者可能将淡味香烟作为戒烟替代选择的担忧。
