Web-based intervention on the promotion of physical activity among Iranian youth using the transtheoretical model

The Effect of a Physical Activity Program Using WhatsApp on Adolescents' Exercise Behavior

This study aims to demonstrate the effect of a transtheoretical model (TTM)-based physical activity program on the exercise behavior of adolescents using WhatsApp. The study was conducted with high school students (N = 185) in a pre-/posttest, quasi-experimental design. TTM-based text messages were sent to the intervention group (n = 95) over WhatsApp every day for 8 weeks. The intervention group demonstrated more statistically significant progression in the exercising stages of change compared to the control group (n = 90) (χ2 = 20.10; p = .00). It was also found that this group had a higher exercising self-efficacy score (t = 2.647; p = .009) and a higher physical activity total metabolic equivalent of task score (Z = -3.521; p = .000). There was no significant difference in BMI and perception of pros and cons (p > .05). The program was found to be effective in terms of recording progress in the exercising stages of change, increasing exercising self-efficacy, and maintaining a physical activity program.

Evaluating the effectiveness of Internet-based communication for public health: a systematic review (Preprint)

Background

Communicating strategically is a key issue for health organizations. Over the past decade, health care communication via social media and websites has generated a great deal of studies examining different realities of communication strategies. However, when it comes to systematic reviews, there is fragmentary evidence on this type of communication.

Objective

The aim of this systematic review was to summarize the evidence on web institutional health communication for public health authorities to evaluate possible aim-specific key points based on these existing studies.

Methods

Guided by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement, we conducted a comprehensive review across 2 electronic databases (PubMed and Web of Science) from January 1, 2011, to October 7, 2021, searching for studies investigating institutional health communication. In total, 2 independent researchers (AN and SS) reviewed the articles for inclusion, and the assessment of methodological quality was based on the Kmet appraisal checklist.

Results

A total of 78 articles were selected. Most studies (35/78, 45%) targeted health promotion and disease prevention, followed by crisis communication (24/78, 31%), general health (13/78, 17%), and misinformation correction and health promotion (6/78, 8%). Engagement and message framing were the most analyzed aspects. Few studies (14/78, 18%) focused on campaign effectiveness. Only 23% (18/78) of the studies had an experimental design. The Kmet evaluation was used to distinguish studies presenting a solid structure from lacking studies. In particular, considering the 0.75-point threshold, 36% (28/78) of the studies were excluded. Studies above this threshold were used to identify a series of aim-specific and medium-specific suggestions as the communication strategies used differed greatly.

Conclusions

Overall, the findings suggest that no single strategy works best in the case of web-based health care communication. The extreme variability of outcomes and the lack of a unitary measure for assessing the end points of a specific campaign or study lead us to reconsider the tools we use to evaluate the efficacy of web-based health communication.

The Effectiveness of Web-Based Interventions to Promote Health Behaviour Change in Adolescents: A Systematic Review

Although web-based interventions are attractive to researchers and users, the evidence about their effectiveness in the promotion of health behaviour change is still limited. Our aim was to review the effectiveness of web-based interventions used in health behavioural change in adolescents regarding physical activity, eating habits, tobacco and alcohol use, sexual behaviour, and quality of sleep. Studies published from 2016 till the search was run (May-to-June 2021) were included if they were experimental or quasi-experimental studies, pre-post-test studies, clinical trials, or randomized controlled trials evaluating the effectiveness of web-based intervention in promoting behaviour change in adolescents regarding those health behaviours. The risk of bias assessment was performed by using the Effective Public Health Practice Project (EPHPP)-Quality Assessment Tool for Quantitative Studies. Fourteen studies were included. Most were in a school setting, non-probabilistic and relatively small samples. All had a short length of follow-up and were theory driven. Thirteen showed significant positive findings to support web-based interventions' effectiveness in promoting health behaviour change among adolescents but were classified as low evidence quality. Although this review shows that web-based interventions may contribute to health behaviour change among adolescents, these findings rely on low-quality evidence, so it is urgent to test these interventions in larger controlled trials with long-term maintenance.

"I feel too lethargic to do physical activity": Perceptions of Iranian adults on the barriers to perform regular physical activity

Background: Despite the intention to perform physical activity (PA), a number of individuals cannot manage to have PA program on a regular basis. In this study we explored the barriers of regular PA behavior among healthy adults in Tabriz, Iran.

Methods: This qualitative study with a conventional content analysis approach, was carried out from June to September 2020. Nineteen 30-59 years old individuals, were purposefully (purposive sampling) selected to participate in the study. The participants were formerly registered as "physically inactive" in the health records of Tabriz Health System. Individual semi-structured interviews were conducted until data saturation. Data were managed using MAXQDA-10 software.

Results: The barriers of regular PA that emerged from our data were being listless and lethargic, non-supportive environment, disintegration in PA education chain, and restrictive social norms.

Conclusion: Our findings uncover several PA barriers that are less discussed in the literature. Poor level of regular PA among adults in Iran, as a developing context, is rooted in perceptions with social and economic origins, which should be taken into account by public health policy makers while planning PA promotion programs in such communities. To promote regular PA among healthy adults in developing countries, regular PA programs should be tailored to bridge the gap between their recognition of PA barriers and subsequent behavior change through creating group dynamics highlighting the measures to diminish the behavior.

Mobile-application intervention on physical activity of pregnant women in Iran during the COVID-19 epidemic in 2020

BACKGROUND

Considering the low level of physical activity in pregnant women in the COVID-19 pandemic period, and on the other hand, the benefits of mobile application (mobile app) learning, we decided to conduct a study to determine the impact of educational intervention based on mobile app on physical activity in pregnant women.

MATERIALS AND METHODS

The present study was quasi-experimental and examined 93 pregnant women aged 16-20 weeks of gestation. Sampling was done on pregnant women participating in the childbirth preparation classes in Isfahan. We used the validated and reliable questionnaire including perceived benefits, perceived barriers, perceived enjoyment, perceived social support, and Pregnancy Physical Activity Questionnaire. The intervention was based on mobile app, and the content of the application contained 12 main domains such as description of physical activity and benefits and barriers of exercise in the pregnancy, different types of proper pregnancy exercise, planning for exercise, and different types of exercise. Finally, data were analyzed using SPSS20, and the Chi-square test, independent t-test Paired t-test were employed. The significance level was considered to be <0.05.

RESULTS

The results showed that, after the intervention based on mobile app, the mean score of perceived benefits and enjoyment were significantly higher than before the intervention in the intervention group. Finally, total mean score of physical activity significantly increased in the intervention group, while the change decreased in the control group.

CONCLUSION

The results indicated that the use of mobile app can be used to promote physical activity in pregnant women. Therefore, it is recommended that mobile app education should apply with face-to-face classes in health centers for physical activity in pregnant women in the pandemic situation.
