Background: Flight and cabin crew are known to be at increased risk for\natherosclerotic cardiovascular disease (ASCVD). However, ASCVD risks have\nnot yet been compared in flight and cabin crew in low resource settings like\nsub-Saharan Africa. Objectives: To assess absolute ASCVD risk estimate and\nits clinical correlates among flight and cabin crew. Methods: From June 1st\n2015 to December 30th 2015, 379 consecutive aviation navigants (Flight crew:\n62.5%, pilots: 46.2%, women: 29.6%, Caucasians 23.2%) were enrolled in a\ncross-sectional survey of ASCVD risk estimate using the Framingham tools.\nThey underwent a physical examination for either initial or renewal medical\ncertificate Class 1 or 2 including blood chemistry, ECG, and echocardiogram\nas per International Civil Aviation Organization (ICAO) and Civil Aviation\nAuthority (CAA-DRC) medical regulations. We modeled the risk of moderate\nand high ASCVD estimate in a stepwise logistic regression. Results: Low,\nmoderate and high ASCVD risk estimates were observed respectively in 248\n(65.4%), 64 (16.9%), and 67 (17.7%) navigants. Moderate and high ASCVD\nrisk estimates predominated among flight than cabin crew (23.6% vs. 5.6%; p\n< 0.0001 and 28.3% vs. null; p < 0.001), low ASCVD risk estimate among cabin\n than flight crew ............
