Abstract: Objective To analyze the relationship between reading habits and cognitive function among workers in an industrial park in Ningxia. Methods In an industrial park in Ningxia,convenience sampling was used to select all workers in some units for questionnaire survey and cognitive function assessment,and multiple linear regression model was constructed to analyze the relationship between reading habits and cognitive function of workers. Results A total of 1 764 workers were surveyed in an industrial park in Ningxia,of which 523 （29.65%） were engaged in the production and processing of starch,amino acids,and aginomoto,followed by 380 （21.55%） were engaged in metal smelting and machinery manufacturing. The average age of the workers was （35.48±9.22） years old,and there were 1 440 males （81.63%）. The average cognitive function score of the workers was （15.60±2.48）. Gender,age,educational level,marital status,occupational classification,work shift pattern,drinking,exercise status,and sleep quality were correlated with cognitive function （P<0.05 or P<0.01）. The results of multiple linear regression showed that after adjusting for demographic factors,job factors,lifestyle factors,and behavioral factors,the cognitive function scores of occasional readers （β′=0.100） and frequent readers （β′=0.131） were higher than those of non‐readers （P<0.001）. Conclusions There is a correlation between reading habits and cognitive function of workers. Relevant intervention measures can be taken to cultivate good reading habits and prevent cognitive impairment of workers.
