摘 要:目的:探讨饮茶与非吸烟、非饮酒人群口腔癌的关系。方法采用病例-对照研究设计,收集2010年9月至2015年1月经病理确诊的非吸烟、非饮酒人群口腔癌新发病例203例和同期社区对照人群572名。调查研究对象的人口学特征、吸烟史、饮酒史、饮茶史、既往疾病史、肿瘤家族史、职业史等。应用非条件logistic回归模型估算饮茶与非吸烟、非饮酒人群口腔癌发病风险的调整OR (95%CI)值,并进一步对性别、年龄、居住地、被动吸烟进行分层分析,以及对饮茶与被动吸烟进行相乘交互作用分析;利用超额相对危险度(RERI)、归因比(AP)和交互作用指数(SI)对饮茶与被动吸烟进行相加交互作用分析。结果与不饮茶者相比,饮茶(OR=0.52,95%CI:0.34~0.81)、开始饮茶年龄≥18岁(OR=0.54,95%CI:0.34~0.85)、无论饮茶年限<20年(OR=0.49,95%CI:0.27~0.90)还是≥20年(OR=0.55,95%CI:0.32~0.95)、平均每日饮茶量<700 ml(OR=0.52,95%CI:0.32~0.86)、饮茶浓度适中(OR=0.56,95%CI:0.32~0.96)、饮淡茶(OR=0.35,95%CI:0.16~0.77)、饮绿茶(OR=0.48,95%CI:0.28~0.82)、饮温茶(OR=0.55,95%CI:0.31~0.98)可降低非吸烟、非饮酒人群口腔癌的风险。分层分析结果显示,在女性(OR=0.53,95%CI:0.30~0.94)、年龄<60岁(OR=0.53,95%CI:0.29~0.97)、居住在城市(OR=0.38,95%CI:0.20~0.69)、无被动吸烟(OR=0.47,95%CI:0.25~0.86)的非吸烟非饮酒人群中,饮茶具有保护作用;饮茶与被动吸烟之间不存在相乘交互作用(OR=0.95,95%CI:0.41~2.20)及相加交互作用(RERI=-0.15,95%CI:-0.92~0.62; AP=-0.16,95%CI:-1.06~0.73; SI=-0.18,95%CI:-1.44~0.87)。结论饮茶、开始饮茶年龄、平均每日饮茶量、饮茶类型、饮茶浓度及饮茶温度对非吸烟、非饮酒人群口腔癌的发生具有一定的影响。Objective To investigate the effect of tea on oral cancer in nonsmokers and nondrinkers. Methods A case-control study were performed between September 2010 and January 2015 including 203 oral cancer cases in nonsmokers and nondrinkers with pathologically confirmed and 572 community controls. The related information included socio-demographic characteristics, detailed information on tobacco smoking and alcohol and tea consumption, personal medical history, family history of cancer, and occupational history were collected from all subjects. Unconditional logistic regression analysis was used to calculate the odds ratios (OR) and 95%confidence intervals (95%CI) to examine the effect of tea on oral cancer and to assess multiplicative interactions between tea and passive smoking. We also stratified by age, sex, residence, and passive smoking to explore possible difference in association between subgroups. Additive interactions between tea and passive smoking were assessed using relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (SI). Results Compared with non-tea drinkers, tea consumption (OR=0.52, 95%CI:0.34-0.81), age of tea drinking initiation (years)≥18 (OR=0.54, 95%CI: 0.34-0.85), duration of tea consumption (years) 〈20 (OR=0.49, 95%CI: 0.27-0.90), duration of tea consumption (years)≥20(OR=0.55, 95%CI:0.32-0.95), average daily tea consumed〈700 ml(OR=0.52,95%CI:0.32-0.86), moderate concentration of tea consumed (OR=0.56,95%CI:0.32-0.96), weak concentration of tea consumed(OR=0.35, 95%CI: 0.16-0.77), drinking green-tea(OR=0.48,95%CI: 0.28-0.82) and drinking moderate temperature of tea (OR=0.55,95%CI: 0.31-0.98) could reduce the risk of oral cancer; Stratified analysis indicated the protective effects of tea drinking on female (OR=0.53,95%CI:0.30-0.94), age〈60 years old (OR=0.53,95%CI:0.29-0.97), live in the urban(OR=0.38,95%CI:0.20-0.69) and no pas
