摘要Background: Incense burning is a popular religious practice in Chinese elderly. The objective of this study is to investigate the association between incense burning and cognitive health in community elderly persons.
Methods: Cross sectional study. 848 stroke-free elderly persons were recruited. Cognitive functions were assessed using the Montreal Cognitive Assessment (MoCA), Hong Kong List Learning Test (HKLLT), Rey Complex Figure Test and Recognition Trial (RCFT) Color Trails Test (CTT), animal fluency, Symbol Digit Modalities Test (SDMT), and Modified Boston Naming Test (MBNT). Chinese incense burning habits were self-reported and recorded as if one burned incense, if one burned incense indoors, frequency of incense burning in a year and if one burned incense daily. Levels of air pollutants outdoor including fine particulate matter (PM 2.5), Nitrogen Dioxide (NO2), Ozone (O3) and Sulfur Dioxide (SO2) over the past year were recorded from the Air Quality database of the Department of Environment Protection. Multiple linear regression analysis was used to examine the relationships between cognitive scores and incense burning habits adjusting for age, education and levels of outdoor air pollutants.
Results: If one burned incense showed a negative association MoCA (B = -0.905, SE = 0.243), SDMT (B = -1.728), animal fluency (B = -0.921), RCFT Immediate recall (B = -2.601), and RCFT Delayed recall (B = -2.363). If one burns incense indoor showed a negative correlation MoCA (B = -0.793), SDMT (B = -1.621), animal fluency (B = -0.960), RCFT Immediate recall (B = -1.784) and RCFT Delayed recall (B = -1.653). Frequency of incense burning in a year showed a negative association with MoCA (B = -0.001), animal fluency (B = -0.001), RCFT Immediate recall (B = -0.002), RCFT Delayed recall (B = -0.002). If one burns incense daily showed a negative association with MoCA (B = -0.675), animal fluency (B = -0.0904), RCFT Immediate (B = -1.722), RCFT Delayed (B = -1.512). p<0.05 for all.
Conclusions: Chinese incense burning may have small but significant negative influence on multiple cognitive domains including global cognition, information processing speed, executive function and non-verbal memory. Longitudinal studies are needed to confirm such associations.
