To assess obesity as a risk factor for tooth loss over 5 years in an urban sample of Brazilian adults.
A total of 1586 individuals were surveyed using a multistage probabilistic approach. Five years later, 635 individuals 14-64 years old were re-examined. An incident case of tooth loss was determined for a participant that had lost at least one tooth over time. Obesity was evaluated by calculating body mass index at baseline and by the change in obesity status over time.
Incident cases of tooth loss were significantly more frequent among obese (47.1%) than normal-weight individuals (32.4%) (p = .004). Obese individuals had 31% higher risk [relative risk (RR) =1.31; 95% confidence interval (95%CI) 1.04-1.65] for tooth loss than normal-weight individuals adjusting for age, socio-economic status, smoking, dental care and periodontitis. This association was significant for females (RR=1.47, 95%CI 1.08-2.01), but not for males. The risk for tooth loss was also modified by presence of periodontitis at baseline and lifetime smoking exposure. There was an increased risk for tooth loss for those that remained obese than those that remained normal weight.
Obesity is associated with higher risk for tooth loss. This association was modified by sex, periodontal status and smoking.
在巴西成年人的城市样本中，评估肥胖作为 5 年内牙齿缺失的风险因素。
采用多阶段概率方法对 1586 名个体进行了调查。 5 年后，重新检查了 635 名 14-64 岁的个体。对于随时间至少缺失一颗牙齿的参与者，确定了牙齿缺失的偶发病例。通过基线时计算体重指数和随时间肥胖状况的变化来评估肥胖。
肥胖者（47.1％）发生牙齿缺失的偶发病例明显多于体重正常者（32.4％）（p=0.004）。 调整年龄，社会经济地位，吸烟，牙齿护理和牙周炎后，肥胖个体的牙齿缺失风险高 31％（相对风险（RR）=1.31；95％置信区间（95％CI）为 1.04-1.65）。对于女性（RR=1.47，95％CI 1.08-2.01），这种关联具有统计学意义，但对于男性则没有。 牙周炎的存在和终生吸烟暴露也改变了牙齿缺失的风险。与那些保持正常体重的人相比，那些仍然肥胖的人发生牙齿缺失的风险更高。
肥胖与牙齿缺失的风险增加有关。这种关联受性别，牙周状况和吸烟的影响。
