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.
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。
