Improving physical activity and metabolic syndrome indicators in women: A transtheoretical model-based intervention

Abstract

Background:This study aimed at investigating the impact of an educational intervention based on transtheoretical model to increase physical activity and improve metabolic syndrome indicators in women.Methods:In this quasi-experimental study, 142 women with metabolic syndrome were randomly assigned to the case and control group (each group 71 participants). SECQ (Marcus), processes of change (Marcus), decisional balance (Bandura) and self-efficacy (Nigg) questionnaires and International Physical Activities Standard Questionnaire in preintervention, 3 and 6 months after intervention were completed. Furthermore, abdominal obesity, triglycerides (TG), and high-density lipoprotein (HDL) were measured. Physical activity intervention based on transtheoretical model (TTM) was performed in the case group. Finally, data were analyzed by SPSS (16) (SPSS Inc., Chicago, IL, USA) and repeated measure ANOVA, independent t-test and Freidman was used. A two-tailed P value, lower than 0.05, was considered to be statistically significant.Results:After the intervention, physical activity level increased in the intervention group, and they also progressed in stages of change, but the people in the control group had regressed. All changes in TTM constructs were significant in the intervention group during the time and differences in pros and cons were not significant in the control group. Abdominal obesity and TG has significantly reduced, and HDL has increased in the intervention group. In the control group, there was a significant increase in TGs and a decrease in HDL.Conclusions:Physical activity training based on TTM can improve physical activity and metabolic syndrome indicators in women.

O modelo transteórico para auxiliar adolescentes obesos a modificar estilo de vida

“…A partir desta perspectiva, o Modelo Transteórico de Mudança (MTT) tem sido adotado por diferentes profi ssionais de saúde como estraté-gia em intervenções para perda de peso por meio da mudança do estilo de vida em adolescentes (Han, Gabriel, & Kohl, 2015;Mostafavi, Ghofranipour, Feizi, & Pirzadeh, 2015;Prochaska, Norcross, Fowler, Follick, & Abrams, 1992). O MTT foi descrito pela primeira vez pelos autores Prochaska e DiClemente (1983) que analisaram e compararam 29 diferentes tipos de psicoterapias que auxiliavam indivíduos a realizarem modifi cações comportamentais e concluíram que tal mudança se dá ao longo do tempo, sendo um processo mediado por quatro dimensões: os estágios de prontidão para mudança, os processos de mudança, os marcadores da mudança e o contexto da mudança (Prochaska, DiClemente, & Norcross, 1992).…”

“…Os autores nomearam dez processos de mudança, cinco cognitivo/experienciais e cinco comportamentais. A autoefi cácia e a tomada de decisão para a mudança representam os marcadores da adesão a um estilo de vida saudável (Mostafavi et al, 2015), enquanto o contexto da mudança é representado pelo ambiente interno (personalidade, história de vida e recursos cognitivos) e ambiente externo (relacionamentos interpessoais, contexto social; Velicer, DiClemente, Rossi, & Prochaska, 1996).…”

Validation of Health Behavior and Stages of Change Questionnaire

“…These stages are pre-contemplation, contemplation, preparation, action, maintenance, relapse, and termination 4. The model has been used widely, showing its effectiveness in behaviors such as quitting smoking,5,6 alcohol intake,7 eating habits,8 physical activity,9,10 and use of screening tests 11,12. To evaluate the stages of change, these studies are supported by criteria constructed from proposed definitions,6,11,12 self-report questionnaires,9,13,14 or evaluating various groups of behaviours 15…”

Effect of cardiac rehabilitation on metabolic syndrome and its components: A systematic review and meta-analysis

“…[10111213] CR is a complex interventional therapy, which is defined as “comprehensive long-term services involving medical evaluation, prescribed exercise, cardiac risk-factor modification, health education, counseling, and behavioral interventions” by the U.S. Department of Health and Human Services and the National Heart, Lung, and Blood Institute. [1415] As it is well-documented that exercise training and diet at least partly reverse MetS,[10] it would be useful to determine the efficacy of CR on MetS patients too. Although various studies were conducted to test the effect of CR on MetS patients, there are still inconsistent results on the effect of CR on reverse MetS and also its components.…”
