To ascertain whether habitual green tea consumption is associated with sarcopenia among Japanese older adults, using the screening tool for sarcopenia (SARC-F). This cross-sectional study in Mukawa, Hokkaido, Japan, was conducted between June and September 2022 and included 364 Japanese participants older than 65 y. Habitual green tea consumption and energy intake were ascertained using a validated self-administered food frequency questionnaire. Sarcopenia was evaluated using the SARC-F. Multivariable logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of sarcopenia risk across participant tertiles of green tea consumption, with adjustments for age, sex, body mass index, living alone, habitual exercise, walking hours, current smoking status, current alcohol consumption status, energy intake, protein intake, vegetable intake, and fruit intake. In this study of 364 participants (154 men and 210 women), the prevalence of sarcopenia risk was 9.3%. The multivariable-adjusted OR [95% CI] of green tea consumption for ≥1 cup/d compared with that of <1 cup/wk of sarcopenia was 0.312 [0.129-0.752]. Higher habitual green tea consumption was inversely associated with sarcopenia among Japanese older adults. Further longitudinal studies are required to confirm these findings.
为了确定习惯性饮用绿茶是否与日本老年人的肌肉减少症有关，我们使用肌肉减少症筛查工具（SARC-F）。这项横断面研究于 2022 年 6 月至 9 月在北海道向川町进行，共纳入 364 名年龄大于 65 岁的日本参与者。习惯性饮用绿茶和能量摄入情况使用经过验证的自我管理食物频率问卷进行评估。使用 SARC-F 评估肌肉减少症。采用多变量逻辑回归分析，根据参与者习惯性饮用绿茶的 tertiles 估计肌肉减少症风险的比值比（OR）和 95%置信区间（CI），调整因素包括年龄、性别、体重指数、独居、习惯性运动、步行时间、当前吸烟状况、当前饮酒状况、能量摄入、蛋白质摄入、蔬菜摄入和水果摄入。在这项对 364 名参与者（154 名男性和 210 名女性）的研究中，肌肉减少症风险的患病率为 9.3%。与每周饮用绿茶<1 杯相比，每天饮用绿茶≥1 杯的多变量调整 OR（95%CI）为 0.312（0.129-0.752）。习惯性饮用绿茶量较高与日本老年人的肌肉减少症呈负相关。需要进一步的纵向研究来证实这些发现。
