ABSTRACT Our objective was to test the effect of physicians providing brief health lifestyle counseling to patients with type 2 diabetes mellitus during usual care visits.
We conducted a randomized controlled trial of a 12-month intervention at 2 large community health centers, enrolling 310 patients with a body mass index (calculated as weight in kilograms divided by height in meters squared) of 25 or greater. In the intervention group, self-management goals for nutrition and physical activity were set using a tailored computer program. Goals were then reviewed at each clinic visit by physicians. The control group received only printed health education materials. The main outcome measures included change in physical activity and body weight.
In the intervention group, recommended levels of physical activity increased from 26% at baseline to 53% at 12 months (P< .001) compared with controls (30% to 37%; P= .27), and 32% of patients in the intervention group lost 6 or more pounds at 12 months compared with 18.9% of controls (odds ratio, 2.2; P= .006).
A brief intervention to increase the dialogue between patients and health care providers about behavioral goals can lead to increased physical activity and weight loss.

    ABSTRACT: Background: We obtained the prevalence of overweight/obesity, weight-loss attempts, and weight-related counseling and treatment among U.S. adults who sought care in federally funded community health centers. We investigated whether racial/ethnic and gender disparities existed for these measures.Methods: Data came from the 2009 Health Center Patient Survey. Measures included body mass index (BMI), self-perceived weight, weight-loss attempts, being told of a weight problem, receipt of weight-related counseling, nutritionist referrals, weight-loss prescriptions, and cholesterol checks. We conducted bivariate analyses to determine distributions by race/ethnicity and gender, then ran logistic regressions to examine the effects of several sociodemographic factors on weight-loss attempts and on being told of a weight problem.Results: Overall, 76% of adult patients seen in health centers were overweight or obese (BMI ≥ 25.0 kg/m(2)); 55% of overweight patients, and 87% of obese patients correctly perceived themselves as overweight. There were no racial/ethnic differences in BMI categories or self-perceptions of weight. Females were more likely than males to be obese and also more likely to perceive themselves as overweight. About 60% of overweight/obese patients reported trying to lose weight in the past year. There were no racial/ethnic disparities favoring non-Hispanic White patients in weight-related treatment. Women were more likely than men to receive referrals to a nutritionist or weight-loss prescriptions. Overweight/obese patients had higher adjusted odds of a past-year weight-loss attempt if they perceived themselves as overweight (OR = 3.30, p < 0.0001), were female (OR = 1.95, p < 0.05), African American (OR = 3.34, p < 0.05), or Hispanic/Latino (OR = 2.14, p < 0.05). Overweight/obese patients had higher odds of being told they had a weight problem if they were Hispanic/Latino (OR = 2.56, p < 0.05) or if they had two or more chronic conditions (OR = 2.77, p < 0.01).Conclusions: Patients seen in community health centers have high rates of overweight and obesity, even higher than the general U.S. population. Efforts to address weight problems during primary care visits are needed to reduce the burden of obesity and its sequellae among health center patients.

    ABSTRACT: We consider the design of codes for differential space-time modulation in the presence of large numbers of transmit and/or receive antennas. Based on the novel upper bound on the pairwise-error probability of differential space-time modulation for large numbers of antennas, we show that Euclidean distance is an appropriate code performance indicator in the large-array regime. For two transmit antennas, we use the new design criterion to obtain new differential codes with large minimum Euclidean distance. Simulations of bit-error-rate confirms that the new codes has improved the performance of differential codes for large numbers of receive antennas.
