目的确定咬合力和自然牙数量对日本老年人体重指数（BMI）下降的独立影响。设计3至6年的纵向研究。地点：日本城市和农村地区。参与者独立生活的日本成年人，基线年龄为69-71岁和79-81岁。这项分析排除了基线时体重过轻的参与者，收集了年龄、性别、咬合力、牙齿数量、BMI、社会经济因素、病史、每日处方药数量、认知功能、抑郁症状、握力和身体功能等信息。使用压敏片测量最大咬合力。使用BMI评估营养状况，BMI <21.5的参与者被定义为体重不足。然后，他们被分为两组：一组是“BMI下降”组，在3年或6年的随访调查中被定义为体重不足，另一组是“BMI保持”组，在两次随访调查中都没有被定义为体重不足。Logistic广义估计方程（GEE）模型被用来评估咬合力的影响，并在基线上的牙齿数量在BMI下降超过3或6年，调整后可能的协变量与营养状况。ResultsThe最终分析包括704名参与者。86名（12.2%）参与者被归类为BMI下降组。Logistic GEE模型显示，牙齿数量与BMI下降无显著相关性。然而，咬合力与BMI下降显着相关（比值比= 0.90，95%置信区间= 0.83-0.97）调整后的协variates.ConclusionParticipants咬合力较低的更有可能是在BMI小于21.5 kg/m2。研究结果表明，预防口腔功能下降对维持营养状态很重要。
ObjectivesTo determine any independent influence of occlusal force and of number of natural teeth on decline in body mass index (BMI) among older Japanese adults.DesignLongitudinal study over a 3‐ to 6‐year period.SettingUrban and rural area in Japan.ParticipantsIndependently living Japanese adults aged 69–71 years and 79–81 years at baseline. This analysis excluded participants who were defined as underweight at baseline.MeasurementsInformation was collected on age, gender, occlusal force, the number of teeth, BMI, socioeconomic factors, medical history, the number of daily prescription medications, cognitive function, depressive symptoms, hand grip strength, and physical function. Maximal occlusal force was measured with a pressure‐sensitive sheet. Nutritional status was assessed using BMI, and participants with BMI <21.5 were defined as underweight. Then, they were divided into two groups: a “BMI declined” group who were defined as underweight at either 3‐ or 6‐year follow‐up survey, and a “BMI maintained” group who were not defined as underweight at both follow‐up surveys. Logistic generalized estimating equation (GEE) models were used to assess the effect of occlusal force and the number of teeth at baseline on decline in BMI over 3 or 6 years, after adjusting for possible covariates associated with nutritional status.ResultsThe final analysis included 704 participants. Eighty‐six (12.2%) participants were classified into the BMI declined group. Logistic GEE models showed that the number of teeth was not significantly associated with decline in BMI. However, occlusal force was significantly associated with decline in BMI (odds ratio = 0.90, 95% confidence interval = 0.83–0.97) after adjusting for covariates.ConclusionParticipants with lower occlusal force were more likely to be in the BMI less than 21.5 kg/m2. The findings suggest that to prevent decline in oral function is important to maintain nutritional status.
