Objective: to measure the engagement of nursing workers and verify the association between engagement and sociodemographic variables in these workers. Method: quantitative cross-sectional research, with nursing workers, from the Mother and Child Department, of a private and philanthropic hospital, in the city of São Paulo - SP/Brazil. Data collection took place in 2022, via the REDcapTM digital platform, with sociodemographic questions and the UWES-9 (Utrecht Work Engagement Scale). Descriptive analyzes were carried out and correlations between variables were obtained using Spearman's correlation coefficient, using the free software R version 4.2.2 for the analyses. Result: for half of the 210 respondents, all dimensions and the total scale score presented median values above 5.00, indicating high worker engagement. The variables Age and Professional category had a positive statistical association with engagement, and it was identified that nursing workers who did not have health issues in the previous month had a higher median score. Conclusion: the study showed high participant engagement, with all items scoring greater than or equal to 5.00. Engagement was positively correlated with the variables age, with greater engagement among older ages, and with the professional category, which showed the highest median score among nursing assistants and technicians, 5.33, while nurses had a median score of 5.06.
