Abstract

ABSTRACT Teachers often undertake nighttime work involving exam corrections, projects and devising lesson plans in their homes. Many present excessive daytime sleepiness (EDS) and depression. Objective: The objective of this study was to evaluate EDS and depression in teachers from public schools. Methods: 201 female teachers were evaluated in the district of Quipapá/PE, Brazil. Among the study sample, 38 working 1 shift (CONTROL 1), 40 working 2 shifts (CONTROL 2) and 123 working 3 shifts (WTeachers-3T). The subjects were submitted to evaluation by the Epworth Sleepiness Scale and Beck Depression Inventory (BDI).The EDS data were analyzed by the Kruskal-Wallis test with Dunn's multiple comparison, p<0.05 and expressed in MEDIAN (MINIMUM - MAXIMUM) whereas the depression data were analyzed by the Chi-square test, with p<0.05, expressed in percentage. Results: WTeachers-3T presented excessive daytime sleepiness and higher rates of mild (24%) and moderate (37%) depression compared to controls - Control 1: mild (8%) and moderate (11%) - Control 2: mild (5%) and moderate (15%). Conclusion: This study found that teachers in the Quipapá municipality of Penambuco state working three shifts showed excessive daytime sleepiness and a higher percentage of mild and moderate depression compared to teachers working only one (1) or two (2) shifts.
