Outline
To investigate whether there are differences in anxiety status and influencing factors between health examination populations undergoing first-time and non-first-time low-dose spiral computed tomography (LDCT).
This retrospective study involved individuals who underwent health examinations at a tertiary health management center from January to December 2023 (including LDCT and anxiety self-assessment scales). Participants were divided into first-time LDCT examination group and non-first-time LDCT examination group based on whether it was their first examination at this hospital. Univariate analysis utilized independent two-sample t-tests or χ2 tests. Four models were established for the overall population: Model 1 did not adjust for confounding factors; Model 2 adjusted for age, gender, examination type, occupation, education level, and alcohol history; Model 3 further adjusted for previous history of pulmonary nodules, diabetes, and hypertension; Model 4 included Body Mass Index (BMI) adjustments based on the same variables in Model 3.
A total of 19 892 participants were included in this study, with an overall anxiety detection rate of 12.31%. The anxiety detection rate in the non-first-time LDCT examination group (14.27%) was higher than that in the first-time LDCT examination group (8.9%), with a statistically significant difference (χ2=122.878, P<0.05). After adjusting for the aforementioned confounding factors, the anxiety risk for those undergoing non-first-time LDCT was 1.519 times that of those undergoing first-time LDCT (OR=1.519, 95%CI: 1.374-1.68, P<0.001).
The non-first-time LDCT examination is an independent risk factor for anxiety in health examination populations.
