Meta Analysis
Effect of obesity on short- and long-term mortality postcoronary revascularization: a meta-analysis.
Overweight and obesity are often assumed to be risk factors for postprocedural mortality in patients with coronary artery disease (CAD). However, recent studies have described an "obesity paradox" -- a neutral or beneficial association between obesity and mortality postcoronary revascularization. We reviewed the effect of overweight and obesity systematically on short- and long-term all-cause mortality post-coronary artery bypass grafting (CABG) and post-percutaneous coronary intervention (PCI). ⋯ Compared to non-obese individuals, overweight and obese patients have similar or lower short- and long-term mortality rates postcoronary revascularization. Further research is needed to confirm the validity of these findings and delineate potential underlying mechanisms.

To determine the factors associated with state legislative action to address childhood obesity. ⋯ The socioeconomic conditions of the state and its political climate strongly predict legislative action to address childhood obesity. The finding that Democratic governors and state legislatures not controlled by Republicans are associated with greater policy action against obesity suggests that the 2006 election may result in additional action against obesity in certain states. This study can also be used to guide the efforts of public health advocates, who can achieve greater success by targeting their efforts toward states with conducive political environments.

The objective of this study is to examine whether adolescents' measured BMI and self- or mother's perception of weight status at age 14 are associated with depression at age 21. ⋯ This study suggests that the perception of being overweight during adolescence is a significant risk factor for depression in young adult men and women. The perception of being overweight during adolescence should be considered a possible target for a prevention intervention.

Comparative Study
Lifestyle factors and incident mobility limitation in obese and non-obese older adults.
This study examines the association between incident mobility limitation and 4 lifestyle factors: smoking, alcohol intake, physical activity, and diet in well-functioning obese (n = 667) and non-obese (n = 2027) older adults. ⋯ These results underscore the importance of a healthy lifestyle for maintaining function among non-obese older adults. However, a healthy lifestyle cannot overcome the effect of obesity in obese older adults; this stresses the importance of preventing obesity to protect against mobility loss in older persons.

Randomized Controlled Trial
Improved insulin sensitivity and adiponectin level after exercise training in obese Korean youth.
The objective of this study was to investigate the association among adiposity, insulin resistance, and inflammatory markers [high-sensitivity C-reactive protein (hs-CRP), interleukin (IL)-6, and tumor necrosis factor (TNF)-alpha] and adiponectin and to study the effects of exercise training on adiposity, insulin resistance, and inflammatory markers among obese male Korean adolescents. ⋯ Obese Korean male adolescents showed reduced adiponectin levels and increased inflammatory cytokines. Six weeks of jump rope exercise improved triglyceride and insulin sensitivity and increased adiponectin levels.
