ACSM addresses myths about weight loss, exercise

Dear ACSM members and certified professionals, Last Friday, an article appeared in Time magazine making statements that we believe run counter to fact and the public interest. The article claimed that exercise, contrary to the research with which we’re all familiar, is not an effective health tool, particularly as it pertains to weight loss. While an ACSM member and expert was consulted for the story, he agrees that his research and opinions were selectively reported. Among its numerous claims, the story would have us believe that: Losing weight matters more than being aerobically fit in preventing heart disease One can’t lose weight from exercise because exercise makes you hungrier – and willpower can’t conquer the hunger enough to make good food choices Exercising 60 to 90 minutes most days of the week in order to lose weight (a recommendation from an ACSM Position Stand) is unrealistic Leisure-time physical activity – just moving around more during the day – is more effective for weight loss than dedicated exercise Vigorous exercise depletes energy resources so much that it leads to overeating – i.e., weight gain Your assistance is needed in getting the right health message out to the public. These suggested talking points will help you dispel myths and confirm the value of exercise to your patients, clients and colleagues.   Also, we encourage you to adapt this letter to the editor and submit it to your local news outlets, helping readers and viewers get the best evidence-based facts and information.   Thank you for your involvement as we continue to increase awareness of the true benefits and advantages of a regular physical activity program.   Sincerely, The American College of Sports Medicine

FW: Three decade change in the prevalence of hearing impairment and its association with diabetes in the United States

Three decade change in the prevalence of hearing impairment and its
association with diabetes in the United States

Objective: to examine the secular change of the prevalence of hearing impairment over three decades in U.S. adults with and without diabetes.Methods: the cross-sectional National Health and Nutrition Examination Surveys (NHANES, the 1971-1973 [NHANES I] and the 1999-2004 [NHANES 1999-2004]) were used. Average pure-tone audiometry thresholds in decibels (dB) at 1, 2, 3, 4 kHz frequencies of the worse ear were used to represent the participants' hearing status. Any hearing impairment was defined as average pure-tone audiometry threshold of the worse ear >25 dB.Results: From 1971 to 2004, among adults without diabetes aged 25 to 69 years, the unadjusted prevalence of hearing impairment decreased from 27.9% to 19.1% (P <0.001), but among adults with diabetes there was no significant change (46.4% to 48.5%). After adjustment for age, sex, race, and education, the prevalence of hearing impairment in the NHANES I and NHANES 1999-2004, respectively, was 24.4% (95% confidence interval
[CI], 22.3-26.6%) and 22.3% (95% CI, 20.4-24.2) for adults without diabetes and 28.5% (95% CI, 20.4-36.6%) and 34.4 (95% CI, 29.1-39.7%) for adults with diabetes. The adjusted prevalence ratios of hearing impairment for persons with diabetes vs. those without diabetes was 1.17 (95% CI, 0.87-1.57) for the NHANES I and 1.53 (95% CI, 1.28-1.83) for NHANES 1999-2004.Conclusions: Persons with diabetes have a higher prevalence of hearing impairment, and they have not achieved the same reductions in hearing impairment over time as have persons without diabetes.
