Night shift workers refer higher urinary symptoms with an impairment quality of life. a single cohort study

BACKGROUND: Our aim is to assess the impact of night shift work (NSW) on urinary symptoms.METHODS: Between March 2018 and October 2018, we evaluated a group of National Health care system workers. Urinary symptoms and quality of life were measured by Overactive Bladder Questionnaire Short Form (OABq-sf). Clinical variables (i.e. age, smoking status, medical history) were collected and analyzed according to be NS workers (NSWs) -subjects working at least one time from 8pm to 8am- or traditional workers (TWs). Univariate and multivariate analysis was performed to identify predictive variables of worse OAB outcomes (OABq-sf >30, OABq-SB≥ 12, OABq HRQL≥ 18).RESULTS: A total of 136 participants (68 males and 68 females) were included in the study. On OABq-sf, total score, symptoms bother (OABq-SB) and health related quality of life (OABq-HRQL) domains were significantly (p<0.05) higher in NSWs group, respectively: 31 (IQR 26-35) Vs 19 (IQR 19-20); 11 (IQR 10-13) Vs 6 (IQR 6-7); 19 (IQR 16-22) Vs 13 (13-14). Finally, seven NSWs (10.6%) referred nocturia respect to only one (1%) TWs, (p=0.02). On multivariate analysis NSW was an independent predictor of OABq-sf> 30 units (OR:30; CI: 9-111, p=0.001), OABq-SB ≥ 12 units (OR:16, CI:6-43 p=0.001) and OABq HRQL ≥ 18 units (OR:20, 6-70, p = 0,001).CONCLUSIONS: Night shift workers presented worst OAB score and poor QL when compared to similar traditional workers. Long-term data on NSWs patients are also needed to further clarify this relationship.
