To investigate the association between edentulism and obesity in the Swedish population aged 55–84 years over a 22-year period as a result of changes in health and socio-economic factors.
Subjects aged 55–84 years (n = 16 416) were randomly sampled from the Swedish population by Statistics Sweden on four occasions (1980–81, 1988–89, 1996–97 and 2002). Trained interviewers collected information about dental status and anthropometric, demographic, socio-economic, lifestyle and health-related factors. Statistical analyses were based on logistic regression models.
Edentulism decreased from 43% to 14% in the age group 55–84 years from 1980 to 2002, and the proportion of subjects with removable dentures decreased from 68% to 33%. In the age group 55–74 years, the proportion of subjects with low education decreased from 60% to 28%, and the proportion of obese subjects (body mass index ≥30 kg/m²) increased from 9% to 15%. In women aged 55–74 years, the association between obesity and edentulism, adjusted for health, lifestyle and socioeconomic factors, was significant in all surveys, and the odds ratio for obesity changed from 1.64 (95% confidence interval 1.18–2.27) in 1980 to 3.17 (95% confidence interval 1.69–6.18) in 2002. In men, the association was weaker and was significant only in the sample that combined all surveys and included individuals aged 55–84 years.
The study indicated an association between edentulism and obesity, which was most obvious in women aged 55–74 years.
研究在 22 年的时间里，由于健康和社会经济因素的变化，55-84 岁瑞典人群中缺牙与肥胖之间的关系。
瑞典统计局于 1980-81 年、1988-89 年、1996-97 年和 2002 年四次从瑞典人群中随机抽取 55-84 岁的受试者（n=16416）。经过培训的调查员收集了有关牙齿状况以及人体测量、人口统计学、社会经济、生活方式和与健康相关因素的信息。统计分析基于逻辑回归模型。
1980 年至 2002 年，55-84 岁年龄组的缺牙率从 43%降至 14%，可摘义齿的比例从 68%降至 33%。在 55-74 岁年龄组中，受教育程度低的比例从 60%降至 28%，肥胖人群（体重指数≥30kg/m²）的比例从 9%增至 15%。在 55-74 岁的女性中，肥胖与缺牙之间的关联在所有调查中均经健康、生活方式和社会经济因素调整后具有统计学意义，肥胖的优势比从 1980 年的 1.64（95%置信区间 1.18-2.27）变为 2002 年的 3.17（95%置信区间 1.69-6.18）。在男性中，关联较弱，仅在结合所有调查并包括 55-84 岁人群的样本中具有统计学意义。
该研究表明，缺牙与肥胖之间存在关联，在 55-74 岁的女性中最为明显。
