Abstract

The aim of the study was to analyze the factors influencing the depression score in patients with occupational lung diseases. We have conducted a cross-sectional study on patients with a diagnosis of occupational lung disease evaluated for their current health status in the Colentina Clinical Hospital during October 2017. Patients with severe reduction in lung function or during exacerbations periods were excluded from the study. The patients' status was evaluated based on the standard medical procedures of the clinic. The quality of life was assessed using the Saint George Questionnaire. The Hospital Anxiety Depression Score provided the information on the depression level. We found a high prevalence of depression (53.65%). Depression score was highly directly correlated with the activity score (R= 0.60, p<0.05), with the impact score (R= 0.70, p<0.001) and negatively related to the forced expiratory flow in one second percentage (% FEF1) from the reference value (R = -0.41, p <0.005). The high depression score patients (HD) had significantly lower FEF1 compared to the low score depression (LD) ones (average HD = 70.85, average LD = 87, p < 0.001) and lower FEF1 to vital capacity index (average HD = 70.17%, average LD = 76.78%, p < 0.05). The average activity and impact score were also significantly different (p <0.05). Age, gender, BMI and duration of exposure had no influences on these relations, but the co-morbidities were of significant differences (chi2 = 60.96, p <0.05). Even if BMI was not statistically different, the frequency of the metabolic syndrome related diseases was higher (66% in high score depression group vs 53% in the low depression one). We concluded that depression score in occupational diseases is frequent, even before the lung function is severely reduced. Depression is associated with the degree of lung function reduction and with the number and the severity of comorbidities.
