Sleep-apnea risk and subclinical atherosclerosis in early-middle-aged retired National Football League players.

PURPOSE: Limited data from former National Football League (NFL) players suggest that obstructive sleep apnea (OSA) may be highly prevalent after retirement. It remains unclear whether the high prevalence of OSA in retired players is comparable to nonathletes. This retrospective analysis compared sleep apnea (SA) risk in retired NFL players to a community cohort (CARDIA Sleep study), and examined associations between SA risk and cardiovascular risk factors, including subclinical atherosclerosis. MATERIALS AND METHODS: Retired NFL players (n=122) were matched to CARDIA Sleep participants by age ±2 years (range 37-55 years), body mass index ±2 kg/m2, race, and male sex. Participants underwent electron-beam computed tomography to measure coronary artery calcium (CAC) and completed the Berlin Questionnaire to determine SA risk. The presence of CAC was defined as an Agatston score >0. RESULTS: Retired NFL players had a greater prevalence of high SA risk than the matched CARDIA Sleep participants (27% vs 11.5%, P=0.002). Compared to the CARDIA Sleep participants, retired players were less likely to smoke, and had higher blood pressure, lower fasting glucose levels, and higher cholesterol levels. However, there was no difference in the prevalence of detectable CAC (30% vs 30%, P=1). In both players and the community cohort, SA risk was not significantly associated with CAC after controlling for age, race, and body mass index. CONCLUSION: Retired NFL players have a greater prevalence of high SA risk but similar prevalence of CAC compared with a well-matched community cohort.

Characteristics of problem drinking in an urban South American indigenous population.

This 2002 Medcen Foundation-funded study explored characteristics of problem drinking among 211 urban Venezuelan Native Americans of Arawak origin. Prevalence of problem drinking using Alcohol Use Disorders Identification Tests was 88.5% among men and 17.3% among women. Periodic binge drinking was marked by loss of control, failure to meet obligations, and alcohol-related trauma. Focus group participants noted that previous occasional binge drinking by men has been replaced by frequent male and female heavy weekend drinking, violence, and death. Limitations and implications are discussed. Awareness of high levels of problem drinking and desire for assistance present compelling mandates for community intervention efforts.

Prevalence of problem drinking in a Venezuelan Native American population.

This is the first study of alcohol-related problems among a Latin American indigenous population using the Alcohol Use Disorders Identification Test (AUDIT). A randomly selected community sample consisting of 3% of the adult population of the tribe completed oral interviews (n = 105 adults, completion rate 86%). The majority of both men (98%) and women (53%) had drunk alcohol at some time in their lives, with 94 and 26% respectively having consumed alcohol within the past 12 months. Using a cut-off score of 8 for the AUDIT, 86.5% of all men and 7.5% of all women were found to be problem drinkers. Focus group discussions revealed that traditional patterns of binge drinking of corn liquor had gradually been replaced by consumption of commercial beer and rum at more frequent intervals and with more negative social consequences. This male population demonstrates one of the highest prevalence rates for problem drinking reported in the world literature. Both the magnitude of problems detected and participants' concerns about them suggest that broad-scale interventions are warranted at the community level.
