Much of the data associated with cardiovascular disease risk factors and circadian rhythms are done on shift workers; due to their line of work typically causing circadian disruption and sleep loss (Loef et al., 2019). Previous research incorporating chronotype and its influence on shift work has been explored; however, there is limited research focusing on law enforcement officers. Additionally, no known research has investigated the effect of chronotype on CVD risk factors among law enforcement officers. The aim of this study was to investigate the cardiovascular disease risk factors in law enforcement officers and their relationship with chronotypes. This cross-sectional study, utilized a convenience sample of adult male and female police officers (n = 36) from one southeast Georgia sheriff department. Chronotypes were assessed using the Reduced Morning Evening Questionnaire (rMEQ), additionally blood pressure and blood lipid panel were measured. rMEQ categorized the LEOs into Morning (n=11), Intermediate (n=16), and Evening Type (n=9). Results show no significant difference found between chronotypes related to cardiovascular health. However, descriptive findings highlight the elevated cardiovascular risk among LEOs. Future research should focus on other factors that relate to chronotypes such as stress or the level of involvement to have a range of all chronotypes and different scales of health for individuals.
