BUFFALO, N.Y. -- A police officer who works the night shift, typically from 8 p.m. to 4 a.m., already is at a disadvantage when it comes to getting a good "night's" sleep.
Add frequent overtime to that schedule, and an officer may be climbing into bed as the sun comes up, setting the stage for short and unrestful slumber.
A new study published in the current issue of Archives of Environmental & Occupational Health (vol. 64, No. 3) shows that this combination of night work, overtime and shortened sleep can contribute to the development among police officers of the metabolic syndrome, a combination of unhealthful factors that increase the risk of cardiovascular disease (CVD), primarily heart disease and stroke.
John M. Violanti, PhD, research associate professor in UB's Department of Social and Preventive Medicine in the School of Public Health and Health Professions, is first author on the paper, and received significant contributions from biostatisticians in the CDC's National Institute for Occupational Safety and Health (NIOSH).
"These findings reinforce the scientific value of studying the effects of occupation on cardiovascular risk factors," said Violanti. "This is especially important in first responders, who are selected on initial good overall physical and mental health. Exploring specific job-related associations, such as shift work, add to the benefit of such investigations."
The research is based on data from the Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) study, which has been ongoing since 2003. Metabolic syndrome is defined as abnormalities in any three of five important clinical measures: abdominal obesity, triglycerides, high-density lipoproteins (HDL), blood pressure and fasting glucose level.
This baseline study involved 98 police officers who were selected randomly from a total of 934 officers. Clinic personnel in UB's Center for Preventive Medicine obtained a fasting blood sample, and measure
