Learning Objective 1: The learner will be able to conceptualize that there are labor settings that have high risks for sleep and metabolic disorders.

Learning Objective 2: The learner will be able to identify how scientific evidence can support proposals for preventive health care, health disturbances identification and intervention.


Sleep is essential for healthy physiological functioning and life. Sleep disorders (SD), including most problems in sleep behavior, have been implicated in the development of chronic diseases. In order to achieve its implicit security goals, police officers are entailed to continuous shift works. Our aim was to search association of SD and risk factors for type 2 diabetes in Mexican police officers.


A group of 55 police officers underwent anthropometric assessment, blood glucose and glycosilated hemoglobin (HbA1c) determinations. SD were evaluated using the Sleep Heart Health Study Sleep Habits Questionary (SHQ), and Spanish-language validated for use with Mexican Americans an Mexicans. Descriptive statistics and X2 were performed to examine association between SD and risk factors of type 2 diabetes, 95% CI.


Mean age of the sample was 32 ± 8 years. 30.9% of participants reported SD; 70.9% snoring; 9.1% reported witnessed apnea during sleep; 21.8% reported urgency to move the legs sometime during the last year, and 18.2% unpleasant or uncomfortable sensations in the legs. Although no one reported having diabetes, 32 (58%) of participants had HbA1c values greater than 6%. Mean Hb1Ac was 8.52% (4.3-13.9%). 12 h fasting glycaemia mean value was 100 ± 28 mg/dl. The X2 analysis showed associations between DS, glucose and HbA1c (p=0.0001).


SD showed significant associations with glucose and HbA1c. Although not diagnosed diabetics, 58% of the police officers had elevated HbA1c. These findings reinforce the importance of establishing prevention and control measures to be performed by the nursing team in this occupational group. In addition to the multiple risk factors inherent in public security work, police and their shift work may be associated with high risk for metabolic disease.
