          Abstract

          OBJECTIVE—The purpose of this study is to determine the optimal duration and intensity of exercise for elderly people for the prevention of the metabolic syndrome.

          RESEARCH DESIGN AND METHODS—The population-based Cooperative Research in the Region of Augsburg (KORA) S4 Survey with 1,653 participants aged 55–74 years was used to investigate the relationship between the metabolic syndrome and physical activity.

          RESULTS—Fifty-seven percent of men and 48% of women showed clinical symptoms of the metabolic syndrome. Leisure activities were common (>80% walked >30 min/day). Sports activities performed regularly for ≤1 h per week reduced the odds of having the metabolic syndrome (odds ratio 0.70 [95% CI 0.49–1.02] for men and 0.74 [0.53–1.04] for women), and sports activities >2 h per week were even more effective (0.62 [0.42–0.92] for men and 0.59 [0.39–0.89] for women). In contrast, activities such as walking and cycling did not have an additional influence.

          CONCLUSIONS—Intense physical activity by the elderly should be promoted in addition to leisure physical activity for the prevention of the metabolic syndrome.

          Association of the metabolic syndrome with both vigorous and moderate physical activity.

          Cross-sectional relationships between moderate and vigorous physical activity and the metabolic syndrome (MS) were examined in the Whitehall II study of civil servants (age 45-68 years). We assessed cardiovascular fitness and body mass index (BMI) as possible mediators of the observed association. Measures of 2-hour glucose, systolic blood pressure, fasting triglycerides, waist-hip ratio, and high density lipoprotein (HDL) cholesterol were obtained in 5153 white European participants. Participants in the most adverse sex-specific quintile for three or more of these risk factors were classified as having MS. Self-reported leisure-time physical activity was categorized into separate moderate and vigorous activity classes. BMI and resting heart rate (HR) were used to estimate body fatness and cardiovascular fitness respectively. The odds ratios (95% CI) for having the metabolic syndrome in the top categories of vigorous and moderate activity were 0.52 (95% CI: 0.40, 0.67) and 0.78 (95% CI: 0.63, 0.96) respectively, adjusted for age, sex, smoking, alcohol intake, socioeconomic status, and other activity. Adjustment for BMI and resting HR substantially attenuated both of the above associations. Moderate and vigorous physical leisure-time activity are each associated with reduced risk of being classified with MS independently of age, smoking, and high alcohol intake. Both vigorous and moderate activities may be beneficial to the MS cluster of risk factors among middle-aged populations. Reduced BMI and increased cardiovascular fitness may be important mediators of this association for both intensities of activity.

            Sex differences in the associations of socioeconomic status with undiagnosed diabetes mellitus and impaired glucose tolerance in the elderly population: the KORA Survey 2000.

            Sex differences in the associations of socioeconomic status (SES) with prevalence of undiagnosed diabetes mellitus, impaired glucose tolerance (IGT) and known risk factors of type 2 diabetes mellitus were investigated in an elderly population. Oral glucose tolerance tests were carried out in 1354 randomly selected subjects (697 men, 657 women) aged 55-74 years in the population-based KORA Survey 2000, Augsburg, Germany. Odds ratios (ORs) and 95% confidence intervals (CIs) for undiagnosed diabetes or IGT by education, occupation and income were estimated using logistic regression controlling for age, waist circumference, blood pressure, triglycerides, physical activity, smoking and alcohol intake. All three SES variables were significantly inversely related to body mass index, waist circumference and low physical activity in women (P < 0.05). In men, these associations were weaker or absent. Using the lowest category as reference, occupational status was significantly associated with undiagnosed diabetes in women (adjusted OR 0.5; 95% CI 0.3-0.8) after controlling for risk factors in multivariate regression. The OR was also reduced with higher income in women (adjusted OR, diabetes: 0.7; 95% CI 0.5-1.03). Among men, no significant relations of the SES indicators with unknown diabetes were observed. However, the odds of having IGT was lower with higher occupational status in men (adjusted OR 0.7; 95% CI 0.5-0.9). Undiagnosed type 2 diabetes was related to low SES defined by occupation or income in women only. In men, low occupational status was independently associated with higher IGT risk. Educational level was not related to glucose disorders in both sexes in the elderly population.

              Cost-effectiveness analysis of different screening procedures for type 2 diabetes: the KORA Survey 2000.

              To compare the cost-effectiveness of different type 2 diabetes screening strategies using population-based data (KORA Survey; Augsburg, Germany; subjects aged 55-74 years), including participation data. The decision analytic model, which had a time horizon of 1 year, used the following screening strategies: fasting glucose testing, the oral glucose tolerance test (OGTT) following fasting glucose testing in impaired fasting glucose (IFG) (fasting glucose + OGTT), OGTT only, and OGTT if HbA(1c) was >5.6% (HbA(1c) + OGTT), all with or without first-step preselection (p). The main outcome measures were costs (in Euros), true-positive type 2 diabetic cases, incremental cost-effectiveness ratios (ICERs), third-party payers, and societal perspectives. After dominated strategies were excluded, the OGTT and HbA(1c) + OGTT from the perspective of the statutory health insurance remained, as did fasting glucose + OGTT and HbA(1c) + OGTT from the societal perspective. OGTTs (4.90 per patient) yielded the lowest costs from the perspective of the statutory health insurance and fasting glucose + OGTT (10.85) from the societal perspective. HbA(1c) + OGTT was the most expensive (21.44 and 31.77) but also the most effective (54% detected cases). ICERs, compared with the next less effective strategies, were 771 from the statutory health insurance and 831 from the societal perspective. In the Monte Carlo analysis, dominance relations remained unchanged in 100 and 68% (statutory health insurance and societal perspective, respectively) of simulated populations. The most effective screening strategy was HbA(1c) combined with OGTT because of high participation. However, costs were lower when screening with fasting glucose tests combined with OGTT or OGTT alone. The decision regarding which is the most favorable strategy depends on whether the goal is to identify a high number of cases or to incur lower costs at reasonable effectiveness.
