To investigate the association between respiratory function and basal metabolic rate (BMR), pulmonary function indices and BMR were measured in 251 elderly persons using a spirometer and a body composition analyzer. Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were more strongly correlated with BMR (r = 0.48 and r = 0.43, p < 0.01) than with lean body mass (r = 0.36 and r = 0.35, p < 0.01) and waist-to-hip ratio (r = -0.29 and r = -0.32, p < 0.01) in elderly men. FVC and FEV1 in elderly men with BMR > or = 1390 kcal/day averaged 4.05 +/- 0.56 L and 3.19 +/- 0.45 L, which were significantly above the values (3.54 +/- 0.51 L and 2.80 +/- 0.42 L, p < 0.01) in men with BMR < 1390 kcal/ day. Prevalences of the subjects with elevated FVC or FEV1 were significantly higher in the group of men with BMR > or = 1390 kcal/day than in those with BMR < 1390 kcal/day (66.0% and 68.0% vs 28.3% and 33.9%, p < 0.01). No significant differences were observed between the postmenopausal women with BMR > or = 1135 kcal/day and those with BMR < 1135 kcal/day. In summary, respiratory function is more closely associated with BMR in elderly persons, compared to lean body mass, waist-to-hip ratio, or body fat mass, and these associations are stronger in men than in women.
为了研究呼吸功能与基础代谢率（BMR）之间的关联，使用肺活量计和身体成分分析仪对251名老年人的肺功能指标和BMR进行了测量。在老年男性中，用力肺活量（FVC）和一秒用力呼气量（FEV1）与BMR的相关性更强（r = 0.48和r = 0.43，p < 0.01），高于与瘦体重（r = 0.36和r = 0.35，p < 0.01）以及腰臀比（r = -0.29和r = -0.32，p < 0.01）的相关性。BMR≥1390千卡/天的老年男性的FVC和FEV1平均分别为4.05±0.56升和3.19±0.45升，显著高于BMR<1390千卡/天的男性（3.54±0.51升和2.80±0.42升，p < 0.01）。BMR≥1390千卡/天的男性组中FVC或FEV1升高的受试者患病率显著高于BMR<1390千卡/天的男性组（66.0%和68.0%对28.3%和33.9%，p < 0.01）。BMR≥1135千卡/天的绝经后女性与BMR<1135千卡/天的绝经后女性之间未观察到显著差异。总之，与瘦体重、腰臀比或体脂量相比，老年人的呼吸功能与BMR的关联更为密切，且这些关联在男性中比在女性中更强。
