Objective

To identify the factors associated with insomnia in health professionals of a public hospital in Trujillo, Peru.

Materials and methods

The Athens Insomnia Scale (AIS) was administered to 220 health professionals. The chi-square test and Student's t-test were used. In addition, the multivariate analysis was performed to identify the variables associated with insomnia.

Results

It was demonstrated that there is less risk of insomnia in professionals under 38 years of age (OR 0.77; 95 % CI 0.68 - 0.87; p < 0.05). There is more risk of insomnia in cases of work overload (OR 4; 95 % CI 1.22 - 9.73; p < 0.05), night shifts (OR 3.12; 95 % CI 1.01 - 9.73; p < 0.05), job tenure of more than 7 years in the hospital (OR 1.50; 95 % CI 1.22 - 1.85; p < 0.001) and low back pain (OR 11.28; 95 % CI 3.61 - 35.28; p < 0.05), the latter being the variable with the highest association value.

Conclusions

Our study suggests that health professionals older than 38 years of age, with low back pain, under work overload, who work night shifts and with a job tenure of more than 7 years in the hospital are more at risk of suffering insomnia.
