Background:
The paucity of empirical evidence supporting a correlation between the utilization of household chemicals and cognitive decline in Chinese older adults.
Methods:
The data utilized for this study originated from the Chinese Longitudinal Healthy Longevity Survey (CLHLS 2018). Using regression models to investigate the relationship between exposure to household chemicals and cognitive decline, and evaluate the impact of different fields on cognitive function.
Results:
The use of household chemicals was associated with a decline in cognitive function (anti-caries agent, OR = 1.68, P = 0.040; air freshener, OR = 2.48, P = 0.002; disinfectant, OR = 1.40, P = 0.033). The more frequent the use of household chemicals, the worse the cognitive function (Model1: OR = 2.54, P = 0.024; Model2: OR = 3.23, P = 0.006; Model3: OR = 3.59, P = 0.003).
Conclusion:
The study has uncovered a correlation between the utilization of household chemicals and cognitive decline in individuals aged 65 years and over in China.
