Cardiovascular disease risk in female firefighters

Abstract

BACKGROUND: Female firefighters are in the minority in the Québec firefighter population and worldwide. To our knowledge, no study has focused on cardiovascular risk factors in female firefighters, and further research in this area is needed to evaluate and reduce the risk of on-duty sudden cardiac death. AIMS: To evaluate the prevalence of cardiovascular disease (CVD) risk factors in female firefighters in Québec. METHODS: A cross-sectional study using an online questionnaire to evaluate lifestyle and CVD risk factors and symptoms. RESULTS: Forty-one female firefighters (age: 38.2 ± 9.9 years) participated in this study, representing ~7% of all female Québec firefighters. The prevalence of obesity (body mass index ≥ 30 kg/m2), hypertension, dyslipidaemia, type 2 diabetes mellitus, smoking and physical inactivity was 12% (95% confidence interval [CI] 4-26%), 5% (95% CI 0.6-19%), 5% (95% CI 0.6-19%), 3% (95% CI 0.1-14%), 14% (95% CI 5-29%) and 62% (95% CI 5-7%), respectively. Among survey participants, 76% (59-88%) had moderate to high CVD risk according to the 2013 American College of Sports Medicine guidelines. Eighty-two per cent of participants did not meet the National Fire Protection Association's required cardiorespiratory fitness standard of 12 metabolic equivalents. CONCLUSIONS: A high proportion of female firefighters in this study were at moderate to high risk of CVD. These findings suggest that they would benefit from healthy lifestyle initiatives.
