Objective To investigate the dietary structure in long-haul truck drivers,especially their vitamin A(VA) intake,food sources and serum level.Method One hundred and forty-five long-haul truck drivers were enrolled.A 24-hour dietary recall was conducted by food frequency questionnaire using three-dimensional food models.Serum VA was measured by HPLC.Results The average intake of energy,protein,fat and carbohydrate in working days was 3.95 MJ(945 kcal/d,35.0%RNI),40.7g/d(17.2% energy),20.5g/d(19.5% energy),134.5g/d(56.9% energy) respectively.In rest days,the average intake of energy,protein,fat and carbohydrate was 11.72 MJ(2802 kcal/d,116.8%RNI),118.5g/d(15.0% energy),92.4g/d(37.7% energy),307.2g/d(38.9% energy) respectively.VA intake was 252.6?gRE/d(31.5% RNI) in working days compared to 602.3?gRE/d(75.2% RNI) in rest days.The average serum VA concentration was 583 ?g RE/L,and the prevalence of serum VA
