Exercise training in obese older adults prevents increase in bone turnover and attenuates decrease
In the study to determine the independent and combined effects of weight loss and ET(weight training) on bone metabolism in relation to bone mineral density (BMD) in obese older adults, indicated that the addition of ET to weight loss therapy among obese older adults prevents weight loss-induced increase in bone turnover and attenuates weight loss-induced reduction in hip BMD despite weight loss-induced decrease in bone-active hormones(1).

Physical activity advertisements that feature daily well-being improve autonomy and body image
In the study to investigates whether framing physical activity in advertisements featuring distinct types of goals differentially influences body image and behavioral regulations based on self-determination theory among overweight and obese individuals, showed that there are immediate framing effects on physical activity behavioral regulations and body image from reading a one-page advertisement about physical activity and that gender and BMI moderate these effects. Framing physical activity as a way to enhance daily well-being positively influenced participants' perceptions about the experience of being physically active and enhanced body image among overweight women, but not men(1).

Diet and physical activity behaviors among Americans trying to lose weight
In the study to investigate the Behavioral Risk Factor Surveillance System, a state-based telephone survey of adults > or =18 years of age (N = 184,450) conducted in the 50 states, the District of Columbia, and Puerto Rico in 2000, showed that the prevalence of trying to lose weight was 46% (women) and 33% (men). Women reported trying to lose weight at a lower BMI than did men; 60% of overweight women were trying to lose weight, but men did not reach this level until they were obese. Adults who had a routine physician checkup in the previous year and reported medical advice to lose weight vs. checkup and no medical advice to lose weight had a higher prevalence of trying to lose weight (81% women and 77% men vs. 41% women and 28% men, respectively). The odds of trying to lose weight increased as years of education increased. Among respondents who were trying to lose weight, approximately 19% of women and 22% of men reported using fewer calories and > or =150 min/wk leisure-time physical activity(1).

Methods for voluntary weight loss and control
In a study of "Methods for voluntary weight loss and control", found that participants who remain in weight loss programs usually lose approximately 10% of their weight. However, one third to two thirds of the weight is regained within 1 year, and almost all is regained within 5 years. For many overweight persons, achieving and maintaining a healthy weight is a lifelong challenge. Successful weight loss improves several cardiovascular risk factors and diabetic control; effects on mortality are not clear. Several epidemiologic studies have found that weight loss is associated with increased mortality but the reasons for weight loss were not known. Survey data also confirm that many Americans who are not overweight, particularly young women, are trying to lose weight, which may have adverse physical and psychological consequences. Because of the importance of these issues, research on weight and on weight loss and control should assume a high priority on the nation's health agenda(1).

Health-related quality of life and weight loss practices among overweight and obese US adults
In the study to examine the prevalence and association of HRQOL measures as independent moderators of weight loss practices among overweight and obese men and women, showed that mong men with BMI 25-34.9 kg/m2, the odds of trying to lose weight increased for the moderate vs best category of HRQOL but not for the poorest vs best category, and no associations were noted for men with BMI > or = 35 kg/m2. Women with BMI 25-34.9 kg/m2 had reduced odds and decreasing associated trends in the prevalence of trying to lose weight with poorer general health, increased physically unhealthy days, and increased activity limitation days. Conversely, women with 1-13 vs 0 mentally unhealthy days had greater odds of trying to lose weight. Among those trying to lose weight, reducing calories was common (52%-69%, men; 56%-69%, women). Among men, with the exception of recent mental health, poorer levels of HRQOL measures were associated with diminished attainment of recommended physical activity levels. Among women, poorer general health status was associated with diminished attainment of recommended physical activity levels(1).

Descriptive epidemiology of body weight and weight change in U.S. adults
In the review of data on body weight and weight change collected from nationally representative samples of U.S. adults, showed that between 1960 and 1980, the prevalence of overweight among whites increased by 3% in women and by 6% in men. In blacks, however, the prevalence of overweight increased by 7% in women and by 28% in men. Longitudinal body weight measurements taken 10 years apart show that adults younger than 55 years tend to gain weight, whereas those 55 years and older tend to lose weight. The youngest adults gain the most weight, and the oldest adults lose the most weight. In all age groups, women have substantially greater variation in their 10-year weight change than do men(1).
