“…Some studies presented participant losses considered acceptable over the short-(≤ 6 months) (6,12,27) and long-term (> 6 months) (5,8,11,12,26); one study did not give the loss information. We found losses ranging between 11,1% (27) and 63% (24) in the short-term studies and between 17,3% (26) and 46% (5) in the long-term studies. In general, these losses were lower in the CG.…”

“…The predominant design was the randomized clinical trial (5)(6)(7)(8)(9)(10)(11)(12)14,20,22,26,28), but studies of interventions without a control group (CG) (18,26), an experimental (1) and quasi-experimental (24) group were also identified. Only 8 studies clearly described the randomization method used (10,12,14,20,22,(26)(27)(28).…”

“…From the 18 analyzed studies, 14 were conducted in the United States of America, two in the United Kingdom (20,27), one in Brazil (28) and one in Canada (11). The sample size in the studies varied from 71 to 5,407 (average = 1,349) participants, and included male and female participants.…”

“…The average age ranged from 25, 8 to 75 years, with the exception of two studies which samples were composed by preadolescents (26) and adolescents (25) (Table II). The main inclusion criterion for the studies was the presence of an aggravating factor, such as overweight (9,10,18,20,22,27), high blood pressure (12), increased risk of cardiovascular diseases (20), and diabetes mellitus (11). The predominant design was the randomized clinical trial (5)(6)(7)(8)(9)(10)(11)(12)14,20,22,26,28), but studies of interventions without a control group (CG) (18,26), an experimental (1) and quasi-experimental (24) group were also identified.…”

“…The treatment of the CG was generally defined as "usual care" (1,6,7,(10)(11)(12)20,22,8), and only five studies (7,10,12,27,28) described the intensity and type of care. In the majority of the studies, the comparability of the control and intervention groups (IG) was tested on the baseline values (1,(6)(7)(8)(9)(10)(11)(12)14,20,24,25,27,28) for demographical and socio-economic variables, among others, with the exception of two studies (5,22). In the study of Van Wier et al (22,23), the groups were not statistically compared before the intervention, although all the analyses were adjusted by baseline values, which created an adjusted follow-up score.…”

Palabras clave:Modelos Teóricos. Hábitos alimenticios. Ejercicio. Estudios de intervención. Revisión. ResumenIntroducción: el Modelo Tranteórico multiconductual aborda distintas conductas y es una estrategia prometedora para el abordaje de patologías multifactoriales, sobre todo en las enfermedades crónicas. Los resultados iniciales de su empleo han sido favorables, pero no han sido probados con rigor. Objetivos: el objetivo de este estudio fue realizar una revisión sistemática de la efi cacia del Modelo Transteórico en el cambio de hábitos dietéticos y en el grado de actividad física con intervenciones en varias áreas de la conducta. Métodos: se realizó una búsqueda en PubMed y SCieLO utilizando como criterios de búsqueda estudios de intervención realizados antes de 2016 y que incluyeran más de un hábito, incluyendo hábitos alimentarios y/o actividad física. Resultados y conclusión: se identifi caron 18 estudios, con un predominio de ensayos clínicos aleatorizados, estudios realizaos en Estados Unidos de Norteamérica, y uso de Internet y/o teléfono. Los estudios seleccionados tenían como meta el cambio en los hábitos dietéticos. En 5 de los estudios no se incluía la actividad física. El principal resultado de la intervención fue la disminución en el consumo de grasa y el aumento en la ingestión de frutas y verduras, así como un aumento en la actividad física. Estos cambios supusieron progresos en la pérdida de peso. Sin embargo, los trabajos eran metodológicamente débiles, incluyendo una alta tasa de abandonos, y falta de información sobre la aleatorización y cómo se realizó el estudio ciego. AbstractIntroduction: The multi-behavioral Transtheoretical Model (TTM) addresses multiple behaviors and it is a promising strategy to control multifactorial morbidities, such as chronic diseases. The results obtained using the TTM are positive, but are not consistently methodical. Objectives: The aim of this study was to systematically review the effectiveness of the Transtheoretical Model in multi-behavioral interventions for changing eating habits and levels of physical activity. Methods: A search on PubMed and SciELO databases was performed with inclusion criteria set for intervention studies before 2016 using the Transtheoretical Model for more than one behavior, including eating habits and/or engaging in physical activity. Results and conclusion: Eighteen studies were identifi ed; there was a predominance of randomized clinical trials, studies conducted in the United States, and the use of the Internet and/or telephone. The selected studies were aimed at changing eating behaviors; fi ve of the studies did not address physical activity. The main results were reduction of fat consumption, an increase in the consumption of fruit and vegetables, and increases in physical activity, which are progressions in the stages of change and weight loss identifi ed by the Transtheoretical Model. However, the studies showed methodological weaknesses, including high participant loss and the omission of information about randomization...

Issue AddressedHealth behaviour change can be difficult to maintain. Action plans can address this issue, however, there has been little qualitative research to understand how to optimise action plan interventions. This study explored how people engage with a specific type of action plan intervention, the “volitional help sheet,” in a cardiovascular disease (CVD) prevention context.MethodsTwenty adults in the target age for CVD risk assessment (45 to 74 years) with varying health literacy participated in interviews and created an action plan to change their behaviour. Transcripts were analysed using framework analysis.ResultsParticipants described how engagement with plans was related to how personally relevant the target behaviour and the options within the plan were. Also important was participants visualising themselves enacting the plan when deciding which option to choose. Amongst participants who already engaged in a target behaviour, some did not perceive the plan was useful; others perceived the plan as a helpful prompt or a formalisation of existing plans. For some, the barriers to behaviour change were out of the scope of an action plan, highlighting the need for alternative supports.ConclusionThis study provides qualitative insights into unanticipated ways that people with varying health literacy use action plans, providing new guidance for future developers.So What?Not all action plans are created equal. Careful selection of behavioural targets and plan options and encouraging users to imagine the plan may enhance user engagement. Alternative behaviour change strategies should be available if key barriers cannot be addressed by the plan.

Field experiment of a very brief worksite intervention to improve nutrition among health care workers

Despite the potential of worksite interventions to boost productivity and save insurance costs, they tend to be costly and tested in nonrandomized trials. The aim of the present study was to test the ability of a very brief worksite intervention based on implementation intentions to improve nutrition among health care workers. Seventy-nine health care workers were randomly allocated to a control condition or to form implementation intentions using standard instructions or with a supporting tool. Fruit intake and metacognitive processing (operationalized as awareness of standards, self-monitoring and self-regulatory effort) were measured at baseline and follow-up. Participants who formed implementation intentions ate significantly more fruit and engaged in significantly more metacognitive processing at follow-up than did participants in the control condition (ds > .70). The findings support the efficacy of implementation intentions for increasing fruit intake in health care workers and preliminary support for the utility of a tool to support implementation intention formation.
