Resumen:
Background and aim: There is a high prevalence in the Spanish general population of some cardiovascular
risk factors like overweight, obesity and hypercholesterolaemia. But there is lack of research on Spanish
seafarers. On the other hand, there is strong evidence of the cardiovascular risk predictive value of some
biomarkers. The purpose of this work was to study the convenience of the introduction of detailed diet
questionnaires and the measurement of some biomarkers in the pre-embarkation medical examination.
Materials and methods: Seafarers undergoing medical checkup during 2011 in Madrid, Spain (n = 334).
Overweight and obese subjects received general advice on healthy diet and physical activity. Seventy-four of
them were followed up in 2012 and 2013. Glycated haemoglobin (HbA1c), high-sensitivity C-reactive protein
(hs-CRP), thyrotropin (TSH) and microalbuminuria were measured in two selected groups of patients in 2011.
Results: Overweight and obesity were present in 207 (62%) individuals of the studied population. Those
followed up in 2012 and 2013 showed a reduction of body mass index, waist circumference and total
cholesterol values. We observed risk value of HbA1c in 60 (35.5...
