Media reports suggested an increased prevalence of cardiovascular disease and premature death in former National Football League (NFL) players. The prevalence of cardiometabolic syndrome was determined in current active NFL players. The presence of cardiometabolic syndrome was defined as > or =3 of (1) blood pressure > or =130/85 mm Hg, (2) fasting glucose > or =100 mg/dl, (3) triglycerides > or =150 mg/dl, (4) waist circumference > or =100 cm, and (5) high-density lipoprotein cholesterol < or =40 mg/dl. Sixty-nine of 91 players (76%) from 1 NFL team were studied before the 2008 preseason training camp. Cardiometabolic syndrome markers, body mass index (BMI), waist-height ratio, and triglycerides/high-density lipoprotein cholesterol ratio were compared between 69 players and an age- and gender-matched reference population from NHANES (1999 to 2002) and by player position of linemen versus nonlinemen. Blood pressure > or =130/85 mm Hg, glucose > or =100 mg/dl, and BMI > or =30 kg/m(2) were significantly more prevalent in the 69 players than the NHANES cohort (28% vs 17%, p = 0.032; 19% vs 7%, p = 0.002; and 51% vs 21%, p <0.001, respectively), although cardiometabolic syndrome prevalence was similar in both groups. However, cardiometabolic syndrome prevalence, BMI > or =30 kg/m(2), and waist-height ratio >0.5 were significantly more common in the linemen versus the nonlinemen subgroup (22% vs 0%, p = 0.004; 100% vs 32%, p <0.001, and 95% vs 36%, p <0.001 respectively). In conclusion, cardiometabolic syndrome and its individual components were noted in current NFL players, particularly linemen.

    ABSTRACT: Media reports suggest increased cardiovascular mortality in former National Football League (NFL) players. We previously demonstrated that current heavier players already have cardiometabolic syndrome markers: blood pressure (BP) >or=130/85 mm Hg, fasting glucose >or=100 mg/dL, triglycerides >or=150 mg/dL, waist circumference >or=100 cm, and high-density lipoprotein (HDL) <or=40 mg/dL. A prospective study including 69 of 91active players (76%) from one NFL team was performed. We evaluated the presence of an elevated alanine aminotransferase (ALT) in the players. We also analyzed the association of an increased ALT with cardiometabolic syndrome markers, waist-to-height ratio, and triglyceride-to-HDL ratio in current NFL players. ALT >or=30 IU/L was significantly correlated with mean body mass index (BMI), BMI >or=30 kg/m, BP >or=130/85 mm Hg, waist circumference >or=100 cm, and triglycerides-to-HDL ratio >3.5. An elevated ALT was significantly more common in linemen. An elevated ALT was significantly associated with visceral obesity, hypertension, cardiometabolic syndrome markers, and insulin resistance in current NFL players.

    ABSTRACT: Present data about the increased incidence of early cardiovascular disease and mortality in National Football League (NFL) players is conflicting. These findings are particularly concerning given the escalating weight of current football players at the high school, collegiate, and professional levels. Recent studies have confirmed that heavier former NFL linemen have an increased prevalence of cardiovascular disease compared with an age- and sex-matched reference population. Former linemen had a higher prevalence of obesity, lower high-density lipoprotein cholesterol, increased left ventricular mass and left atrial area, and the metabolic syndrome, compared with nonlinemen. There have been sparse data on the cardiovascular health of current players. A recent analysis of one team demonstrated that the cardiometabolic syndrome and its individual components were significantly more common in linemen versus nonlinemen. Because current heavier NFL players already have evidence of the cardiometabolic syndrome and its individual markers, careful medical evaluation of former and active players is warranted to reduce their risks. This medically and ethically indicated intervention, however, might limit interpretation of future longitudinal studies designed to assess mortality endpoints.

    ABSTRACT: In 2006, a newspaper report indicated an increased prevalence of cardiovascular disease and early mortality in retired professional football players compared to professional baseball players. This study included 69 professional football players from a 2008 National Football League training camp and 155 professional baseball players from an American League 2009 spring training site who volunteered to participate in a study of cardiovascular and metabolic risk factors. The prevalence of body mass index > or =30 kg/m(2), waist circumference > or =100 cm, waist/height ratio >0.5, blood pressure > or =130/85 mm Hg, triglycerides > or =150 mg/dl, triglycerides/high-density lipoprotein cholesterol ratio >3.5, high-density lipoprotein cholesterol < or =40 mg/dl, and alanine aminotransferase > or =40 IU/L was determined in baseball players and compared to measurements obtained in a matched cohort from the National Health and Nutrition Examination Survey (NHANES), professional football players, and linemen and nonlinemen subsets. In conclusion, professional baseball players had favorable cardiovascular parameters, with the exception of an increased prevalence of hypertension, compared to the reference population, and professional baseball players had decreased measures of obesity, hyperglycemia, and the cardiometabolic syndrome compared to professional football lineman.
