Abstract:
Objective:To understand the current status of medicinal plant consumption in Chinese elderly people; To explore associated influencing factors.Methods:Data were obtained from the 2018 cross-sectional survey of the Chinese Longitudinal Healthy Longevity Study (CLHLS) of (CLHLS-HF). Individuals aged 65 and above from 23 provinces (autonomous region, municipalities), who had completed the medicinal plant consumption response survey along with other parameters such as physical measurements, were selected as the study subjects. The χ2 analysis and multiple Logistic regression were used to analyse the medicinal plant consumption among the elderly and its influencing factors. Results:A total of 15 442 people were included. Among them, 9 750 were aged 80 and above, and 2 825 were aged 100 and above. 16.3% of Chinese elderly people reported occasional or frequent consumption of medicinal plants, with a higher proportion among males compared to females, urban residents compared to rural residents, and younger age groups compared to elderly groups ( P<0.001 or P<0.05). Among the 23 provinces (autonomous region, municipalities) surveyed nationwide, the proportion of elderly people who occasionally or frequently consume medicinal plants was over 25.0% in 10 regions. Guangdong, Shanghai, and Zhejiang ranked the top three, with percentages of 40.5% (380/939), 36.1% (229/634), and 28.6% (163/569), respectively. Multiple Logistic regression analysis revealed that factors influencing the level of medicinal plant consumption among the elderly included being a centenarian [ OR (95% CI)=1.361 (1.098,1.688), P=0.005], male [ OR (95% CI)=1.194 (1.051,1.358), P=0.005], Han nationality [ OR (95% CI)=1.374 (1.160,1.627), P=0.005], urban residence [ OR (95% CI)=1.917 (1.697,2.167), P=0.005], middle school education or higher education [ OR (95% CI)=2.061 (1.764,2.408), P<0.001], and elementary school [ OR (95% CI)=1.375 (1.183,1.598), P<0.001], current alcohol consumption [ OR (95% CI)=1.208 (1.029,1.418), P=0.021], current exercise [ OR (95% CI)=1.490 (1.325,1.675), P<0.001], regular fruit intake [ OR (95% CI)=1.213 (1.060,1.388), P=0.005], regular [ OR (95% CI)=4.149 (3.563,4.830), P<0.001] or occasional vitamin intake [ OR (95% CI)=5.593 (4.926,6.350), P<0.001], regular [ OR (95% CI)=2.296 (2.007, 2.628), P<0.001]or occasional tea consumption [ OR (95% CI)=3.030 (2.589, 3.545), P<0.001], and comorbidities (≥2) [ OR (95% CI)=1.343 (1.179,1.529), P<0.001], all positively correlated with occasional or frequent medicinal plant consumption among the elderly. Obesity [ OR (95% CI)=0.697 (0.548,0.888), P=0.003] and smoking [ OR (95% CI)=0.746 (0.627,0.887), P=0.001], on the other hand, showed a negative correlation with occasional or frequent medicinal plant consumption. Conclusion:The proportion of Chinese elderly people reporting occasional or frequent medicinal plant consumption is relatively high. However, it remains unclear whether this is based on the unique background of TCM culture or reflects the urgent demand for daily health maintenance among the elderly. Further efforts should be made to strengthen continuous observation, monitoring, and analysis of health outcomes in this population, exploring the potential benefits and risks.
