The habit of reverse smoking is practised in various parts of the world including the Philippines. In this pilot, community-based, cross-sectional study carried out in the region of Cabanatuan City in the Philippines. 61 Filipina reverse smokers and 30 Filipina conventional smokers were interviewed and clinically examined. Seven demographic variables and twelve habit variables were compared in the two study groups. The majority (96.7 per cent) of reverse smokers exhibited palatal mucosal changes including leukoplakia, mucosal thickening, fissuring, pigmentation, nodularity, erythema and ulceration. In comparison, only 26.7 per cent of conventional smokers exhibited mucosal changes predominantly focal pigmentation and mild erythema. This difference was statistically significant at a X2 value of 47.28 (p < .001). Analysis of the other variables indicated that the two study groups differed significantly with regard to age (p < .05), educational attainment (p < .01), use of filtered versus non-filtered cigarettes (p < .001) and duration of smoking in years (p < .01).
世界上包括菲律宾在内的各个地区都存在反向吸烟的习惯。在菲律宾甲万那端市地区开展的这项基于社区的试点横断面研究中，对61名菲律宾反向吸烟者和30名菲律宾传统吸烟者进行了访谈和临床检查。对两个研究组的7个人口统计学变量和12个习惯变量进行了比较。大多数（96.7%）反向吸烟者表现出腭部黏膜变化，包括白斑、黏膜增厚、裂隙、色素沉着、结节、红斑和溃疡。相比之下，只有26.7%的传统吸烟者表现出黏膜变化，主要是局灶性色素沉着和轻度红斑。在X2值为47.28时，这种差异具有统计学意义（p<0.001）。对其他变量的分析表明，两个研究组在年龄（p<0.05）、教育程度（p<0.01）、使用过滤嘴香烟与非过滤嘴香烟（p<0.001）以及吸烟年限（p<0.01）方面存在显著差异。
