Retracted: A School-Based, Peer-Led, Social Marketing Intervention To Engage Spanish Adolescents in a Healthy Lifestyle (“We Are Cool”—Som la Pera Study): A Parallel-Cluster Randomized Controlled Study

Abstract

A school-based, peer-led, SM intervention developed by adolescents attending high schools in low-income neighborhoods effectively improved the healthy choices of their school-aged peers, leading to increased fruit consumption and PA in adolescents of both genders. Furthermore, adolescent males were more sensitive to improvements in healthy choices, showing increased vegetable consumption and decreased sedentary behavior.

Effectiveness of Workplace Interventions for Improving Absenteeism, Productivity, and Work Ability of Employees: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

“…The RCTs that provided health education training to intermediate managers achieved increased performance [46,47]. These results are in accordance with the RCTs aimed at promoting healthy lifestyles in school-based interventions, where adolescent leaders train close peers and achieve effective improvement in their healthy lifestyles [79]. Such peer-led methodologies are considered education between peers or close individuals with similar interests [80].…”

Behavioural and social sciences to enhance the efficacy of health promotion interventions: redesigning the role of professionals and people

“…This is because social environment-and network-related factors appear to be crucial in reaching the goals of initiatives aimed at preventing obesity (Wang Y. et al, 2013;Wang M. et al, 2014). There is some preliminary evidence on the effectiveness of peer influence, peer support and peer education in promoting health-related behaviours for young people (Lau et al, 1990;Borsari & Carey, 2001;Salvy et al, 2012;Tolli, 2012;Jenkinson et al, 2014;Whipp et al, 2015;Aceves-Martins et al, 2017). Internet-and innovation-based initiatives, as well as programmes that appeal to adolescents, may also enhance the effectiveness of preventative interventions by improving healthrelated behaviour change (Whittemore et al, 2013;Chen & Wilkosz, 2014;Aceves-Martins et al, 2017).…”

Delivering in‐school interventions to improve dietary behaviours amongst 11‐ to 16‐year‐olds: A systematic review

“…The target behaviours in the reviewed studies included increasing fruit and/or vegetable consumption (n = 19); improving snacking behaviours (n = 8) (this included both decreasing the intake of energy‐dense nutrient‐poor snacks) and increasing healthy snacks like fruits and vegetables; decreasing sugar‐sweetened beverage (SSB) intake (n = 8); encouragement to eat meals on a regular basis (n = 4); improving general eating behaviours (eg, increase daily nutritional recommended intake of carbohydrates, fibre minerals, protein, and vitamins, n = 5), and reducing daily fat and sugar intake (n = 3) . A number of studies (n = 13) targeted more than one dietary behaviour in their intervention (eg, increasing fruit and vegetable consumption, decreasing SSB and unhealthy snacks consumption) …”

“…An additional seven studies were judged to be at high risk of bias primarily because the individual study designs were identified as not being randomised controlled trials (RCTs). Most of the studies were judged to have at least one domain of unclear risk of bias; this was mainly owing to the selective reporting of features of these studies. The main feature that was not reported was the blinding of participants and/or researchers to group allocation.…”
