PURPOSE: To provide information on the prevalence of obesity and diabetes mellitus (DM) in former professional football players.

METHODS: For this cross-sectional study, 1106 former NFL players were sampled between April 2015 and July 2017. Height and weight were used to calculate BMI; blood samples were obtained from fasted subjects for analysis of fasting blood glucose and hemoglobin A1c. Subjects also completed a questionnaire regarding DM diagnosis. Subjects were assessed for obesity and DM status based on BMI, FBG, HbA1c, and questionnaire results, and stratified by age (20-39, 40-59, 60+), primary career playing position (Big, Big Skill, Skill), and race (Black, White, Other). Statistical analyses included 1-way ANOVA and Tukey post hoc analysis when variances were equal, or Dunnett C statistic for heteroscedastic data. T-tests were used to evaluate differences between groups.

RESULTS: The prevalence of obesity (BMI ≥ 30) for this population was 63.6%, while the overall prevalence of DM and pre-DM was 13.8% and 61.7%, respectively. Prevalence of both DM and self-reported DM diagnosis increased with each 20 year increase in age (p<0.0001). There was a significant effect of BMI on DM status, with obese men more than twice as likely to be diabetic (odds ratio 2.375, 95% CI 1.555-3.628). The “Big” position group were more likely to be obese as compared with “Big Skill” or “Skill” (p<0.0001). Curiously, there was no difference in the prevalence of DM between any of the 3 position groups. When examined further, “Skill” had the highest prevalence of non-obese diabetics, while “Big” had the lowest (p=0.0002), possibly explaining the lack of overall difference in the prevalence of DM between the 3 groups. Although White subjects were older than either Black or Other race subjects, Black subjects had higher BMI and prevalence of obesity than white subjects and, correspondingly, a greater prevalence of DM.

CONCLUSION: Although patterns and trends may reflect those commonly observed in the general population, the prevalence of obesity and DM may be higher in this population than typically reported in the general U.S. population. Furthermore, there may be special consideration that must be given to a former player’s previous training with regards to his risk of developing diabetes, aside from current age, health, and BMI status.
