Secular changes in prediabetes indicators among older-adult Americans, 1999-2010
Caspersen CJ , Thomas GD , Beckles GL , Bullard KM . Am J Prev Med 2015 48 (3) 253-63 BACKGROUND: Sex-specific prediabetes estimates are not available for older-adult Americans. PURPOSE: To estimate prediabetes prevalence, using nationally representative data, in civilian, non-institutionalized, older U.S. adults. METHODS: Data from 7,995 participants aged ≥50 years from the 1999-2010 National Health and Nutrition Examination Surveys were analyzed in 2013. Prediabetes was defined as hemoglobin A1c=5.7%-6.4% (39-47 mmol/mol [HbA1c5.7]), fasting plasma glucose of 100-125 mg/dL (impaired fasting glucose [IFG]), or both. Crude and age-adjusted prevalences for prediabetes, HbA1c5.7, and IFG by sex and three age groups were calculated, with additional adjustment for sex, age, race/ethnicity, poverty status, education, living alone, and BMI. RESULTS: From 1999 to 2005 and 2006 to 2010, prediabetes increased for adults aged 50-64 years (38.5% [95% CI=35.3, 41.8] to 45.9% [42.3, 49.5], p=0.003) and 65-74 years (41.3% [37.2, 45.5] to 47.9% [44.5, 51.3]; p=0.016), but not significantly for adults aged ≥75 years (45.1% [95% CI=41.1, 49.1] to 48.9% [95% CI=45.2, 52.6]; p>0.05). Prediabetes increased significantly for women in the two youngest age groups, and HbA1c5.7 for both sexes (except men aged ≥75 years), but IFG remained stable for both sexes. Men had higher prevalences than women for prediabetes and IFG among adults aged 50-64 years, and for IFG among adults aged ≥75 years. Across demographic subgroups, adjusted prevalence gains for both sexes were similar and most pronounced for HbA1c5.7, virtually absent for IFG, but greater for women than men for prediabetes. CONCLUSIONS: Given the large, growing prediabetes prevalence and its anticipated burden, older adults, especially women, are likely intervention targets. |
Aging, diabetes, and the public health system in the United States
Caspersen CJ , Thomas GD , Boseman LA , Beckles GL , Albright AL . Am J Public Health 2012 102 (8) 1482-97 Diabetes (diagnosed or undiagnosed) affects 10.9 million US adults aged 65 years and older. Almost 8 in 10 have some form of dysglycemia, according to tests for fasting glucose or hemoglobin A1c. Among this age group, diagnosed diabetes is projected to reach 26.7 million by 2050, or 55% of all diabetes cases. In 2007, older adults accounted for $64.8 billion (56%) of direct diabetes medical costs, $41.1 billion for institutional care alone. Complications, comorbid conditions, and geriatric syndromes affect diabetes care, and medical guidelines for treating older adults with diabetes are limited. Broad public health programs help, but effective, targeted interventions and expanded surveillance and research and better policies are needed to address the rapidly growing diabetes burden among older adults.
