Abstract Objective To investigate the pulmonary functions among the elderly in Hangzhou City, so as to provide insights into the management of respiratory diseases among the elderly. Methods Permanent residents at ages of 60 to 75 years were sampled from Hangzhou City from November to December 2020. The pulmonary function was tested using a portable pulmonary function monitor, including large airway function parameters [forced expiratory volume (FVC), forced expiratory volume in a second (FEV₁) and FEV₁/FVC], and small airway function parameters [maximum expiratory flow rate at 75% vital capacity (MEF_75%), the maximum expiratory flow rate at 25% of vital capacity (MEF_25%) and the forced expiratory flow rate (FEF_25%-75%) at 25% to 75% of vital capacity]. The pulmonary functions were compared among the elderly with different genders, ages and body mass index (BMI). Results Totally 314 participants were recruited, including 126 men (40.13%), with a mean age of (68.49±4.47) years and mean BMI of (23.51±2.79) kg/m². The mean FEV₁, FVC, FEV₁/FVC, MEF_25%, MEF_75% and FEF_25%-75% were (1.97±0.53) L, (2.51±0.72) L, (79.79±11.47)%, (0.98±0.53) L/s, (3.84±1.65) L/s and (1.99±0.91) L/s among the participants, respectively. Higher FEV₁ [(2.22±0.55) vs. (1.79±0.43) L, P<0.05], FVC [(2.92±0.75) vs. (2.24±0.55) L, P<0.05], MEF_75% [(4.19±1.82) vs. (3.59±1.49) L/s, P<0.05] and FEF_25%-75% [(2.14±1.07) vs. (1.90±0.77) L/s, P<0.05] were tested among men than among women, and lower FEV₁ [(1.75±0.46) L], FVC [(2.27±0.64) L], MEF_25% [(0.88±0.57) L/s], MEF_75% [(3.39±1.45) L/s] and FEF_25%-75%[(1.79±0.96) L/s] were tested among the elderly at ages of 70 to 74 years. The proportion of large and small airway dysfunctions was 40.45% among the participants. Conclusions The proportion of large and small airway dysfunctions was 40.45% among the elderly in Hangzhou City, and poor pulmonary functions were tested among the women and the advanced elderly.
