“…Our study showed that most of the participants were classified in the earlier stages of change (61.7% in pre-contemplation and contemplation stages), as expected, considering that Cunha et al ( 21 ) found 68% of Brazilian adolescents and in pre-contemplation and contemplation stages. Participants' self-efficacy in the adoption of healthy eating practices and nutritional knowledge were very high.…”

“…The population considered was the total number of senior students from the 19 schools in the Federal District that joined the HSP in 2018-2019, according to information provided by the State Health Secretariat of the Federal District, but excluding rural and night schools. The sample calculation was performed considering the population of 4,183 participants, the distribution of Brazilian adolescents and young adults in the stages of change observed in the literature, in which 68% were in pre-contemplation and contemplation stages ( 21 ), a sampling error of 5% and a 95% confidence level. Thus, the minimum sample size calculated was 310 participants, to which 10% were added to cover possible losses and inconsistencies of questionnaires, totaling 341 participants.…”

ObjectiveThis study aimed at analyzing the association between stages of change, consumption of food markers, and self-efficacy in the adoption of healthy eating practices, adjusted by nutritional knowledge, among Brazilian adolescents and young adults.MethodsA cross-sectional analysis was conducted with 347 individuals from schools in the Federal District, Brazil. They completed a self-administered questionnaire covering: consumption of food markers, stage of change, self-efficacy in the adoption of healthy eating practices, and nutritional knowledge. Adjusted logistic regression was conducted.ResultsParticipants in pre-contemplation (OR = 0.22), contemplation (OR = 0.19), decision (OR = 0.13) and action (OR = 0.40) stages have less chance to have healthy eating than those in maintenance, including fruits and vegetables [pre-contemplation (OR = 0.23), contemplation (OR = 0.19), and decision (OR = 0.09)]. Adolescents and young adults in pre-contemplation (OR = 0.29) and contemplation (OR = 0.37) had lower chances of having low consumption of sugar-sweetened beverages compared to those in maintenance (p < 0.05). Adolescents and young adults in pre-contemplation (OR = 0.38) and contemplation (OR = 0.36) were less likely to have high self-efficacy scores than those in maintenance (p < 0.05). Higher score of self-efficacy was associated with a lower chance of having a high consumption of sugar-sweetened beverages (OR = 1.02; p = 0.032).ConclusionRegardless of nutritional knowledge, individuals in the earlier stages of change are less likely to have an adequate consumption of healthy foods markers, including fruits and vegetables, and low sugar-sweetened beverages consumption. They are also less likely to have high self-efficacy scores than those in maintenance. Nutritional interventions to focus on enhancing self-efficacy among adolescents and young adults in earlier stages of change to improve dietary habits.

“…Sample size calculation was based on expected self-efficacy in the adoption of healthy practices during the intervention period, considering a 15% increase in self-efficacy scores clinically significant, an SD of 4.79, 27 a significance level of 5% and a power of 80%. The distribution of stages of change observed in the literature 28 was also considered: 68%, 12% and 20% in precontemplation/contemplation, decision and action/maintenance stages, respectively. For such conditions, the minimum sample in the smallest intervention subgroup (decision) should be 26 adolescents.…”

Tailored smartphone intervention to promote healthy eating among Brazilian adolescents: a randomised controlled trial protocol

et al. 2020

IntroductionAdolescent eating patterns are characterised by high consumption of unhealthy foods, which has resulted in an increasing prevalence of overweight and chronic diseases. It is crucial to promote healthy eating habits, and nutritional interventions based on the transtheoretical model have been found to be especially effective. Mobile health strategies also seem promising for adolescents. This study aims to outline a smartphone intervention via WhatsApp for adolescents to promote healthy eating consumption, better nutritional knowledge, self-efficacy in the adoption of healthy practices and progress through the stages of change.Methods and analysisThere will be three distinct groups in this randomised study: a general intervention group (GG), in which the participants will receive the same healthy eating messages, based on the Brazilian food guide; a tailored intervention group (TG), in which the participants will receive healthy eating messages based on their stage of change; and a control group (CG), in which participants will receive messages on a different theme. Possession of a smartphone, use of WhatsApp and being a senior student (16–19 years) from a public school of the Federal District of Brazil will be the study’s inclusion criteria. Rural schools will be excluded. The sample size estimated is 390 individuals: 38 in the GG, 314 in the TG and 38 in the CG. The intervention will last 6 weeks, with a daily message sent to the students. We will investigate nutritional knowledge, self-efficacy in the adoption of healthy eating practices, food consumption and stages of change using preintervention and postintervention questionnaires. Memorisation of the messages will be also assessed.Ethics and disseminationThe study was approved by the University of Brasília, School of Health Sciences and Research Ethics Committee. At the end of the study, the participating schools will receive a printed report with the main results of the intervention.Trial registration numberRBR-5b9jk7.

“…In this study, a quarter of the population (25.9%) and two thirds (63.0%) of the CG were in precontemplation and contemplation respectively and 11.1% were in preparation/action, while none of the EG students were in preparation/action, they were only in the precontemplation (41.7%) and contemplation (58.3%) stage, in a study with Brazilian adolescents it was similarly reported that half were in precontemplation, but differed in the preparation/action stage with a higher index (22%), these participants showed greater changes reduced sugary drinks and increased intake of fruits and beans as suggested. [11] This paper shows a greater advance towards the preparation/action stage in the EG having progressed from 0% to 20% at the end, unlike the CG that started with 11% at this stage and ended with 23%, these results agree with those of an article review published in 2014 in the United Kingdom, which assessed the intervention implemented for the participants to improve their lifestyle and their transit through the stages of change according to the transtheoretical model, it was observed that the intervention group progressed more (32.5%) towards the stage of action than the participants of the control group (25.8%).

“…The ESNUT intervention is based on the fundamentals of the transtheoretical model of change, the TMC has been applied to groups to control smoking, alcoholism, physical activity and the ingesting of healthy diets [11] which allows applying flexible teaching strategies adapted to each stage aware of the balance of the decision, and the work and group discussion between peers, as well as the establishment of a behavior agreement for the selection, preparation, and intake of a correct diet, the results shown in the body composition in a more precise way in the participants, support the achievements of the EG students. On the contrary, when there is no theoretical reference, it is difficult to define the contribution to the success or failure of the intervention, as stated by Pember and Knowlden (2017), the limited success of educational interventions in the university context can be the result of lack of evidence and theory-based design.…”

Background and objective: Adolescents have changes in diet when entering university (leaving out and irregularity in mealtimes, low intake of fruits and vegetables and high intake of junk food and sugary drinks), often body self-perception does not match the actual body composition leading young people to unhealthy practices. Nutritional educational interventions have been successful based on the Transtheoretical Model of Change. To assess the effectiveness of the educational intervention for Nutritional Stabilization “ESNUT” (name in Spanish) in body composition, stages of change, body self-perception and the concordance level with BMI of students newly admitted to a university before and in post-intervention follow-ups.Methods: Quasi-experimental study with control group in students from 17 to 21 years newly admitted to a university who agreed to participate in the study. Independent variable: Educational intervention Nutrition Stabilization Model “ESNUT” and dependent variables: body self-perception, body composition, BMI. Instruments: SECA 274 digital stadiometer, InBody 230 Bioimpedanciometer, body silhouettes test and change assessment scale of the University of Rhode Island (URICA). Analysis. Descriptive statistics, student’s t (comparison of means) and Pearson's r (correlation) with support from the statistical program SPSS version 18.Results: About 50% of the experimental group showed normal nutritional status according to the Real BMI but only 17% according to the fat mass percentage in the third month of follow-up was 50%. A discrepancy was observed with the Perceived BMI, 67% had a self-perception of normal weight. In the experimental precontemplation group, at basal near 50%, it finally reduced 20% and placed in preparation/action.Conclusions: The effectiveness of the “ESNUT” intervention was observed in the experimental group through body composition with a reduction in the percentage of fat mass, therefore Overweight/Obesity. Self-perception of body image in its correlated Perceived Body Mass Index (BMI) versus Real BMI increased their level of concord. The transition from pre-contemplation to contemplation was observed in the stages of change, as well as from this towards preparation/action. The control group made little progress due to relapse to predecessor stages and revealed itself in an increase in the percentage of body fat. Both the experimental and control groups tended to underestimate the perceived BMI versus the actual BMI. Clinical importance: Identifying the stage of change allows feedback in the support of the change and motivates the participants according to the stage in which they are.
