Similar effects also appeared in SBP and DBP categories regardless of follow-up duration .
PA+D interventions had larger improvement effects on CVD risk factors than PA alone interventions .
In adults without IGT or diabetes , lifestyle interventions result ed in significant improvements in SBP , DBP , TC , LDL-C , HDL-C , and TG , and might further reduce CVD risk
Structured lifestyle interventions can reduce diabetes incidence and cardiovascular disease ( CVD ) risk among persons with impaired glucose tolerance ( IGT ) , but it is unclear whether they should be implemented among persons without IGT .
We conducted a systematic review and meta-analyses to assess the effectiveness of lifestyle interventions on CVD risk among adults without IGT or diabetes .
Effect of diet and exercise, alone or combined, on weight and body composition in overweight-to-obese postmenopausal women.
Lifestyle interventions for weight loss are the cornerstone of obesity therapy , yet their optimal design is debated . This is particularly true for postmenopausal women ; a population with a high prevalence of obesity yet toward whom fewer studies are targeted . We conducted a year-long , 4-arm r and omized trial among 439 overweight-to-obese postmenopausal sedentary women to determine the effects of a calorie-reduced , low-fat diet ( D ) , a moderate-intensity , facility-based aerobic exercise program ( E ) , or the combination of both interventions ( D+E ) , vs. a no-lifestyle-change control ( C ) on change in body weight and composition . The group-based dietary intervention had a weight-reduction goal of ≥10 % , and the exercise intervention consisted of a gradual escalation to 45-min aerobic exercise 5 day/week . Participants were predominantly non-Hispanic whites ( 85 % ) with a mean age of 58.0 ± 5.0 years , a mean BMI of 30.9 ± 4.0 kg/m(2 ) and an average of 47.8 ± 4.4 % body fat .  Baseline and 12-month weight and adiposity measures were obtained by staff blinded to participants ' intervention assignment . Three hundred and ninety nine women completed the trial ( 91 % retention ) . Using an intention-to-treat analysis , average weight loss at 12 months was -8.5 % for the D group ( P < 0.0001 vs. C ) , -2.4 % for the E group ( P = 0.03 vs. C ) , and -10.8 % for the D+E group ( P < 0.0001 vs. C ) , whereas the C group experienced a nonsignificant -0.8 % decrease . BMI , waist circumference , and % body fat were also similarly reduced . Among postmenopausal women , lifestyle-change involving diet , exercise , or both combined over 1 year improves body weight and adiposity , with the greatest change arising from the combined intervention
