“…Although treatment length was not a significant moderator of treatment effects in the present review, a trend toward more powerful effects with longer treatments was observed (see Figure 3). For adults, extended and continuous care approaches have led to better weight loss maintenance for several years (Perri, 1998; Perri & Corsica, 2002), with meaningful benefits in the management or prevention of diabetes and hypertension (e.g., Knowler et al, 2002; Whelton et al, 1998). The optimal level of treatment contact and duration for pediatric populations has yet to be established.…”

Context-Identifying and evaluating efficacious treatments for pediatric weight loss is of critical importance.Objective-This quantitative review represents the first meta-analysis of the efficacy of randomized controlled trials comparing lifestyle interventions to control conditions. Data Sources-MEDLINE, PsychINFO, and Cochrane Controlled Trials Register were searched up to August 2005.Study Selection-Eligible studies were randomized controlled trials involving lifestyle interventions for pediatric overweight that had as a comparison either a no-treatment or information/ education-only control. The primary outcome of interest was change in weight status. Fourteen trials were eligible, resulting in 19 effect sizes.Data Extraction-Information on study design, participant characteristics, interventions, and results were extracted using a standardized coding protocol.Data Synthesis-For trials with no-treatment controls, the mean effect size was 0.75 (k=9, 95% CI 0.52 to 0.98) at end of treatment and 0.60 (k=4, CI 0.27 to 0.94) at follow-up. For trials with information/education only controls, the mean effect size was 0.48 (k = 4, CI 0.13 to 0.82) at end of treatment and 0.91 (k = 2, CI 0.32 to 1.50) at follow-up. No significant moderator effects were identified.Conclusions-Lifestyle interventions for the treatment of pediatric overweight are efficacious in the short-term with some evidence for persistence of effects. Future research is required to identify moderators and mediators of outcome and to determine the optimal length and intensity of treatment required to produce enduring changes in weight status.

“…7,8 In addition, most weight loss interventions that include physical activity or dietary components show short-term effects, but the majority of participants regain weight within five years of the intervention. 9 Given the complexities of the bio-behavioral pathology of obesity, accumulating data show that simultaneously changing multiple health behaviors is crucial to preventing and effectively tackling obesity, 1,2,10,11 but there is a lack of clarity regarding which combination of strategies is the most effective and sustainable. These obesity-risk behaviors—physical inactivity, unhealthy eating, poor sleep behavior (e.g., voluntary or involuntary sleep deprivation)—are intertwined with each other during daily life and are difficult to improve without considering the contextual factors of the social environment.…”

Social networks and future direction for obesity research: A scoping review

Despite significant efforts to decrease obesity rates, the prevalence of obesity continues to increase in the United States. Obesity-risk behaviors—physical inactivity, unhealthy eating, and sleep deprivation—are intertwined during daily life and are difficult to improve in the current social environment. Studies show that social networks—the thick webs of social relations and interactions—influence various health outcomes, such as HIV risk behaviors, alcohol consumption, smoking, depression, and cardiovascular mortality; however, there is limited information on the influences of social networks on obesity and obesity-risk behaviors. Given the complexities of the bio-behavioral pathology of obesity, and the lack of clear evidence of effectiveness and sustainability of existing interventions that are usually focused on an individual approach, targeting change in an individual’s health behaviors or attitude may not take socio-contextual factors into account; there is a pressing need for a new perspective on this problem. In this review we evaluate the literature on social networks as a potential approach for obesity prevention and treatment: how social networks affect various health outcomes and present two major social network data analyses (i.e. egocentric and sociometric analysis); and discuss implications and future direction for obesity research using social networks.

“…Overweight and obese individuals typically give up the lifestyle and self-regulatory changes they have made during a weight-loss program—such as healthy eating, physical activity, and vigilant record keeping—and regain 30%–50% of the weight loss within 1 year after the program ends (Barte et al, 2010; Jeffery et al, 2000). Maintenance interventions based on a “continued care” perspective rely on active intervention and staff contact over time for participants to sustain skills learned during weight loss, such as record-keeping and problem-solving skills (Perri & Corsica, 2002; Svetkey et al, 2008; Wadden et al, 2005). Although often highly successful at improving weight-loss maintenance when intervention and staff contact are in place, these maintenance interventions may only delay rather than prevent weight regain (Perri & Corsica, 2002; Wadden et al, 2005).…”

Objective Although behavioral weight-loss interventions produce short-term weight loss, long-term maintenance remains elusive. This randomized trial examined whether learning a novel set of “stability skills” before losing weight improved long-term weight management. Stability skills were designed to optimize individuals’ current satisfaction with lifestyle and self-regulatory habits while requiring the minimum effort and attention necessary. Methods Overweight/obese women (N = 267) were randomly assigned to one of two 6-month interventions and assessed at baseline, 6, 12, and 18 months. Maintenance First women participated first in an 8-week stability skills maintenance module, then in a standard 20-week behavioral weight-loss program. Weight Loss First women participated first in a standard 20-week behavioral weight-loss program, then in a standard 8-week problem-solving skills maintenance module. There was no intervention staff contact during the 12-month follow-up (6–18 months). Results As designed, Maintenance First participants lost the same percent of initial weight during the 6-month intervention period as Weight Loss First participants (M = −8.6%, SD = 5.7 vs. M = −9.1%, SD = 6.9, t = −0.6, p = .52). However, Maintenance First participants regained significantly less weight during the 12-month follow-up (6–18 months) than Weight Loss First participants (M = 3.2 lbs, SD = 10.4 vs. M = 7.3 lbs, SD = 9.9, t = 3.3, p = .001, d = 0.4). Conclusion Learning stability skills before losing weight was successful for maintaining weight loss without intervention staff contact during follow-up. These results can inform the study design of future innovative interventions. Trial Registration: ClinicalTrials.gov-NCT00626457.
