This study was conducted to understand how eating speed and oral health condition are associated with obesity in Japanese working men.
We studied a total of 863 men attending an annual medical checkup of the Japanese Maritime Self Defense Force in Sasebo City, Japan. Participants answered a questionnaire about their eating speed, and we examined their anthropometric status in terms of BMI, waist circumference, and oral health condition, especially periodontal disease and number of functional teeth. Multivariate logistic regression analyses adjusting for potential confounding variables were performed.
The multivariate-adjusted odds ratio for waist circumference greater than 90 cm of the 'very fast' group compared to the 'slow, very slow' group was 5.22 (95% confidence interval 1.81-15.06) after adjusting for potential confounding factors. Individuals were more likely to have waist circumference greater than 90 cm if they had a larger 'number of missing functional teeth' (odds ratio 1.14; 95% confidence interval 1.01-1.28) and severe periodontal disease (odds ratio 2.74; 95% confidence interval, 1.46-5.13).
Eating speed, the number of missing functional teeth, and severe periodontal disease are associated independently with larger waist circumference.
本研究旨在了解日本在职男性的进食速度和口腔健康状况与肥胖之间的关系。
我们研究了日本佐世保市日本海上自卫队年度体检的 863 名男性。参与者回答了关于他们进食速度的问卷，我们根据 BMI、腰围和口腔健康状况（特别是牙周病和功能牙数量）检查了他们的人体测量学状况。进行了多变量逻辑回归分析，以调整潜在的混杂变量。
在调整了潜在混杂因素后，与“慢、非常慢”组相比，“非常快”组腰围大于 90 cm 的多变量调整比值比为 5.22（95%置信区间 1.81-15.06）。如果个体缺失的功能牙数量较多（比值比 1.14；95%置信区间 1.01-1.28）和患有严重牙周病（比值比 2.74；95%置信区间 1.46-5.13），则更有可能出现腰围大于 90 cm。
进食速度、缺失的功能牙数量和严重的牙周病与更大的腰围独立相关。
