Mediators of Behavior Change Maintenance in Physical Activity Interventions for Young and Middle-Aged Adults: A Systematic Review

Abstract

There were a number of methodological and statistical limitations in the evidence base. In future, prespecified formal mediation tests should be carried out and could be aided by a formal framework. Social and environmental variables should be considered in addition to intrapersonal variables. Improving knowledge of how to change hypothesized mediators, based on theory and evidence, will reveal how physical activity behavior change maintenance can be achieved. Maintenance research would be enhanced by establishing a formal definition of behavior change "maintenance." PROSPERO registration: PROSPERO 2015:CRD- 42015025462.

Mechanisms of physical activity behavior change in an incentive-based intervention: Mediation analysis.

“…This may support the idea that participants were in the behavioral maintenance stage at six months, in line with the definition of behavior change maintenance adopted in previous systematic reviews (Murray et al, 2017(Murray et al, , 2018; (3) The measured short-term mediators were potentially less relevant for our sample, which had high daily step counts at baseline indicating that they may not have been 'initiating' physical activity behavior.…”

“…Despite this, mediation analyses are not always conducted (MacKinnon, Lockwood, Hoffman, West, & Sheets, 2002). Little is known about what triggers initiation and maintenance of physical activity behavior change and previous attempts at promoting physical activity have had limited success (Murray et al, 2017(Murray et al, , 2018).…”

“…Studies of physical activity interventions have seldom conducted high quality formal mediation analyses (Murray et al, 2018;Rhodes & Pfaeffli, 2010;Teixeira et al, 2015). One systematic review investigated mediators of behavior change maintenance, defined as behavioral changes occurring at least six months post-baseline, in physical activity interventions and revealed severe methodological shortcomings in previous research in this area (Murray et al, 2018). For example, less than one-third of the included studies conducted formal mediation tests, mediation analyses were not pre-specified in published study protocols, and studies rarely measured mediating constructs prior to the physical activity outcome.…”

Design and Validity of a Choice-Modeling Questionnaire to Analyze the Feasibility of Implementing Physical Activity on Prescription at Primary Health-Care Settings

“…Item 5 was designed to assess the stage of change on PAP behavior for PHC professionals, according to the stage of changes of the transtheoretical model [ 43 ]. This question was introduced because many studies have evaluated the lifestyle behavior changes in patients or people [ 44 , 45 ], although currently to produce changes towards positive healthy lifestyles for a long-term time is not recognized as an efficient strategy in HC settings [ 45 ]. The participants of the previous focus group interview sessions [ 12 ] showed a lack of awareness as the majority of their professional colleagues.…”

Desenvolvimento, Avaliação Sensorial E Da Composição Nutricional De Preparações Destinadas a Esportistas

“…Estratégias de promoção da prática de exercícios físicos têm-se tornado crescentes atualmente, implicando melhora da saúde, bem-estar físico e mental, controle do peso, estética corporal e desempenho físico. 1,2 Nesse cenário, a atenção à alimentação de qualidade é importante, tendo em vista que esta é uma das variáveis mais efetivas para o alcance do desempenho físico ideal e recuperação após atividades esportivas. 3,4 Esportistas necessitam de monitoramento constante de sua alimentação e do equilíbrio dos nutrientes, para evitar lesões e complicações variadas no organismo e melhorar a performance corporal.…”
