Abstract：
BACKGROUND: This study aimed to investigate the relationship between an increase in waist circumference (WC) after 1 year and self-reported chewing status in 10,870 Japanese adults who had received health checkups. Subsequently, 8068 participants were included in the final analysis.
METHODS: We defined an increase in WC ≥ 5 cm after 1 year as an unhealthy increase; in total, 613 (7.5%) respondents met this criterion. Chewing status was evaluated using a self-reported questionnaire at baseline; 1080 (13%) respondents were diagnosed with poor chewing status.
RESULTS: After adjusting for age, gender, WC, body mass index (BMI), and chewing status, an increase in WC ≥ 5 cm was found to be positively associated with gender (females: odds ratios [ORs]: 1.206; 95% confidence intervals [CIs]: 1.008-1.443), WC (ORs: 0.967; 95% CIs: 0.954-0.981), BMI (≥25 kg/m2; ORs: 2.194; 95% CIs: 1.715-2.808), and chewing status (poor; ORs: 1.356; 95% CIs: 1.084-1.697).
CONCLUSIONS: These findings suggest that increased WC after 1 year was associated with self-reported poor chewing status in Japanese adults.

摘要：
背景：本研究旨在调查10,870名接受健康检查的日本成年人在1年后腰围（WC）增加与自我报告的咀嚼状态之间的关系。随后，最终分析包括8068名参与者。
方法：我们将1年后WC≥5cm的增加定义为不健康的增加；总计，613名(7.5%)受访者符合这一标准。在基线时使用自我报告问卷评估咀嚼状态；1080（13％）受访者被诊断为咀嚼状态不良。
结果：调整年龄后，性别,WC,体重指数（BMI），和咀嚼状态，发现WC≥5cm的增加与性别呈正相关（女性：比值比[ORs]：1.206；95％置信区间[CIs]：1.008-1.443），WC（OR：0.967；95%CIs：0.954-0.981），BMI（≥25kg/m2；ORs：2.194；95%CIs：1.715-2.808），和咀嚼状态（差；OR：1.356；95%CI：1.084-1.697）。
结论：这些研究结果表明，在日本成年人中，1年后WC升高与自我报告的不良咀嚼状态相关。
