Correlation analysis of hyperlipemia and metabolic diseases for navy pilots

Objective To make a survey on blood lipid levels and blood lipid abnormality classification of the navy pilots who transit to high performance fighter, to analyze the correlation to hyperuricemia (HUA), fatty liver and body mass index (BMI) excess, and to provide the basis for pilot health maintenance. Methods The blood lipid data of 128 navy pilots who transit to high performance fighter were retrospectively analyzed. Pilots were divided into hyperlipidemia and ortholiposis groups by blood fat level. The morbilities of hyperuricemia, fatty liver and BMI excess were compared between groups. Results In selected pilots, hyperlipidemia was accounted for 23.44% (30/128), in which hypertriglyceridemia (HTG), hypercholesteremia, low high-density lipoprotein cholesterolemia (LHDL-C) and combined hyperlipidemia (CHL) was respectively accounted for 14.06% (18/128), 7.03% (9/128), 1.56% (2/128) and 0.78% (1/128). In hyperlipidemia group, 70.00% pilots (21/30) showed BMI excess and 63.33% pilots (19/30) were diagnosed as fatty liver, those were significantly higher than that of ortholiposis group (χ2=15.755, 39.409, P 0.05). Conclusions The morbility of hyperlipidemia in the navy pilots is high and closely correlated with BMI excess and fatty liver. It's suggested to strengthen the prevention of hyperlipidemia in navy transit pilots and to validate intervention as necessary in order to prolong pilot's career and ensure flight safety.
