To examine the concurrent validity of the Chinese version of Physical Activity Neighborhood Environment Scale (PANES-CHN) among urban adults in regional China. With multistage sampling approaches, 801 eligible urban adults aged 35–74 years were recruited from Nanjing municipality of China between July and September of 2019. The neighbourhood built environment features were measured subjectively with PANES-CHN and objectively with geographic information system. The concurrent validity of PANES was assessed using Spearman’s correlations (r_s). Among the total 801 participants, the mean age was 54.4 (standard deviation = 11.5), while 48.7 % were men. Overall, of all the five objectively-measurable built environment characteristics, the Spearman correlations were examined significant between subjective and objective measurements for commercial facilities (item 2) (r_s = 0.19, 95CI%=0.12, 0.25), recreational facilities (item 6) (r_s = 0.10, 95CI%=0.02, 0.16), traffic junctions (item 12) (r_s = 0.15, 95CI%=0.07, 0.22), medical/education facilities (item 17) (r_s = 0.22, 95CI%=0.15, 0.29), but not for public transport stops. Similar scenarios were observed for participants aged 35–60 years, with sufficient physical activity, men or women. The r_s value for medical/education facilities (item 17) was significantly higher in participants aged 35–59 years (0.28 vs. 0.13; p = 0.04) than those aged 60 + years. PANES-CHN generally has an acceptable validity for assessing built environment characteristics among urban adults in China, which implies that PANES-CHN can be used to measure built environment attributes in health-related population studies.

This study aims to investigate the prevalence and associated factors of perceived fatigability among older people aged 60 + years in Nanjing Mu
