Abstract: Objective To understand the current dietary habits of employees in labor-intensive industrial parks in Chengdu and analyze the influencing factors. Methods In August 2022,a large labor-intensive industrial park in Chengdu was randomly selected,and 6 residential areas were randomly selected from the collective dormitories in the industrial park. In each residential areas,employees living in a whole building were randomly selected as survey objects. A self-designed questionnaire was used to investigate 2 558 employees to collect demographic information,dietary habits and other information. Unconditional logistic regression was used to analyze the influencing factors of dietary habits. Results Only 451（17.6%） employees had good dietary habits, and only 746（29.2%） employees had adequate nutrition knowledge. The proportion of people who consumed enough liquid milk and fruits was lower（2.7% and 33.1%）,and the proportion of people who exercised less and ate out too often was higher（92.7% and 59.3%）. Logistic regression analysis showed that employees >35 years old（OR=1.281,95%CI：1.002-1.637）,with higher levels of education（OR₁=1.470,95%CI：1.158-1.867;OR₂=2.099,95%CI：1.493-2.946）,higher satisfaction with their living environment（OR=2.339,95%CI：1.871-2.924）,sufficient knowledge of nutrition（OR=2.903,95%CI：2.306-3.654） had better dietary habits（all P<0.05）. Conclusion The dietary habits of employees in labor-intensive industrial parks in Chengdu are not ideal,and further targeted measures are needed to improve their living environment and strengthen education ad promotion of reasonable dietary health.
