Digital technologies for promotion of healthy eating habits in teenagers

School-based healthy eating interventions for adolescents aged 10-19 years: an umbrella review

BACKGROUND

The benefits of healthy eating are well known, yet adolescent diet is often poor. School based interventions offer a promising option to promote healthy eating, however, evidence is unclear.

AIM

This umbrella review synthesised the current evidence on school-based interventions for healthy eating in adolescents (10-19 years old).

METHODS

Using Joanna Briggs Institute (JBI) umbrella review guidelines, a systematic search was conducted on 11 electronic databases (PubMed, CINHAL, EMBASE, Science Direct, PsycINFO, MEDLINE, Scopus, ERIC, Web of Science, Cochrane Register of Systemic Review and JBI Evidence Synthesis) to identify reviews published between January 2000 and December 2023. Methodological quality was assessed using JBI critical appraisal tool. A narrative synthesis was conducted informed by the World Health Organisation's Health Promoting School (HPS) framework that categorises school-based interventions into three components i.e., health education, school environment changes, and family and community involvement.

RESULTS

Seventeen reviews were identified (including 347 unique primary studies) that were published between 2008 and 2023. 87% of the reviews were based on interventions in high- income countries, limiting applicability to low- and middle-income countries. Fourteen reviews were rated as high, two as moderate, and one was rated as low methodological quality. Evidence from 71% of the reviews (n = 14 reviews, 13 = high methodological quality) found that multi-component interventions (i.e., interventions incorporating more than two components of the HPS framework) improved adolescents' knowledge and behaviour concerning healthy eating. At the individual level, tech-driven healthy eating curricula effectively improved eating behaviours of adolescents. These individual-level interventions proved to be more effective and sustainable when supported by system-level changes, such as modifying school environments including increased availability of healthy foods and involving parents to promote healthy eating for adolescents. However, limited evidence from only three reviews suggests mixed feasibility for technology-based interventions and lower feasibility for multi-component interventions. The lack of information on stakeholder involvement in intervention design is another critical evidence gap.

CONCLUSION

School-based multi-component healthy eating interventions that combine individual-level interventions with system-level changes are effective in promoting healthy eating behaviours among adolescents. Future reviews should assess the effectiveness of participatory approaches in intervention design, feasibility and scale-up studies, and analysing evidence from low- and middle-income countries.

Construction and Validation of an Educational Technology to Promote the Health of Postmenopausal Women with Dry Eye Syndrome

The climacteric heralds a transition from reproductive to non-reproductive life in women, often accompanied by various clinical manifestations such as dry eye, impacting their quality of life. This study focuses on systematically developing and suitability an educational digital booklet to promote eye health practices and prevent problems among postmenopausal women. The methodological approach encompassed semi-structured interviews with women diagnosed with Dry Eye Syndrome (DES), then constructing the material integrating content, script, illustrations, and layout informed by the interview findings. Subsequent validation involved assessment by 24 health experts for content, appearance, and evaluation by a target audience of 22 women. The booklet attained high suitability scores, with a Global Content Validity Index (CVI) of 0.96, indicating superior suitability as judged by experts. Additionally, it achieved a Global CVI of 0.98 for validation by the target audience. In conclusion, the educational booklet emerges as a suitable and reliable resource for promoting eye heath among DES and non-syndrome women, offering significant potential for broader application in relevant populations.

Association between eating habits during adolescence and gestational diabetes: data from the Japan environment and children's study

Purpose

It is difficult to change pre-pregnancy eating habits, yet establishing healthy eating habits before pregnancy is important for preventing gestational diabetes mellitus (GDM). This study aimed to examine whether the weight-loss behavior of avoiding between-meal and midnight snacking in teenagers is associated with a reduction in the risk of subsequent GDM.

Methods

We used a dataset (jecs-an-20,180,131) from a nationwide, prospective birth cohort study, the Japan Environment and Children's Study (JECS). We included 89,227 (85.7% of the total) mother-infant pairs with live births. Participants in their second or third trimester were asked to report their weight-loss behavior during their teenage years. The prevalence of GDM was investigated. Differences in maternal characteristics were examined using chi-square tests. Crude and adjusted logistic regression models were constructed to assess the associations of various maternal characteristics with the weight-loss behavior of avoiding between-meal and midnight snacking during teenage years.

Results

A total of 2,066 (2.3%) participants had GDM. Weight-loss behavior in teenagers was associated with a decreased risk of GDM. Among participants with normal weight or overweight prior to pregnancy, the adjusted odds ratios were 0.79 (95% confidence interval, 0.70-0.89) and 0.82 (95% confidence interval, 0.69-0.98), respectively.

Conclusions

The results suggest that teenage weight-loss behaviors, such as avoiding between-meal and midnight snacking, are associated with a decreased risk of developing GDM.

It was conducted according to the following stages: preparation of the educational booklet; appearance and content validation with 21 judges and validation with a target audience of 53 adolescents. The drafting, elaboration, and assembly of the material's layout were performed through data retrieved from the integrative review and interviews. The digital booklet was entitled "Uncomplicating Environmental Health", with 29 pages in the A5 half-page format (14.8 cm width and 21.0 cm height), configured in landscape layout mode, made available for free, and accessible via mobile and fixed devices. The booklet was validated regarding appearance and content, with an overall Content Validity Index of 0.95, and judges' validation through the Suitability Assessment of Materials tool was considered "superior". The booklet achieved the target audience's positive agreement for validation. It was considered valid to be used in health education for adolescents.

A modern web-based health promotion program for patients in Greece with diabetes 2 and obesity: an interventional study

BACKGROUND

Health promotion programs are most beneficial in chronic diseases such as diabetes and morbid obesity, which can be positively affected by changes in attitudes, beliefs, and lifestyle.

OBJECTIVES

This study aimed to develop an internet-based modern Health Promotion model using interactive online applications through continuing education and participation.

METHODS

The goal was to positively impact knowledge, behavior, and quality of life for patients with obesity and/or diabetes. This is a prospective interventional study on patients with obesity or type 2 diabetes. Seventeen two patients who met the inclusion criteria were distributed randomly into two groups (control and intervention) from 2019 to 2021 in Greece. All the participants were given questionaries concerning quality of life anxiety and depression (HADS) attitudes and beliefs, knowledge about their condition and general questions to establish a baseline. A traditional health promotion model was followed for the control group. For participants in the intervention group, a web-based health promotion program was created according to the goals of the research. Participants were instructed to log on 1-2 times a week for 5-15 min, with the understanding that the research team would be monitoring their activities. The website included two knowledge games and personalized educational material based on their needs.

RESULTS

The sample comprised 72 patients (36 in control and 36 in the intervention groups). The mean age was 47.8 years for the control group and 42.7 years for the intervention group (p = 0.293). Both study groups had a significant increase in knowledge score on diabetes (Control group:3,24, Intervention group 11,88 p < 0,001) and obesity (Control group:4,9, Intervention group 51,63 p < 0,001) along with a positive attitude score towards fighting obesity (Control group: 1,8, Intervention group 13,6 p < 0,001). Still, the overall change was more remarkable for the intervention group, as indicated by the significant interaction effect of the analysis. Anxiety was decreased only in the intervention group (Control group:0,11, Intervention group - 0,17 p < 0,005). Analysis for QOL during follow-up showed that Physical Health and Level of Independence was improved in both study groups but the degree of improvement was more significant in the intervention group (Control group 0,31,Intervention group 0,73 p < 0,001). Psychological Health was improved only in the intervention group, with better scores at 6 and 12 months compared to controls (Control group 0,28,Intervention group 1,42 p < 0,001). Furthermore, Social relationships were improved only in the intervention group (Control group 0,02, Intervention group 0,56 p < 0,001).

CONCLUSIONS

The results of the present study showed that the participants in the intervention group showed significant improvement in knowledge, attitudes, and beliefs after using the internet as a learning tool. The intervention group also showed significantly reduced anxiety and depression arising from chronic illness. All of this resulted in an improved quality of life regarding physical Health, mental Health, and social relationships. Technology and online-based health promotion programs can revolutionize how we approach the prevention and management of chronic and terminal illnesses by improving accessibility, personalizing care, increasing engagement and motivation, improving data analysis, and disease management.

Use of Information and Communication Technologies among Adults in Weight Control: Systematic Review and Meta-Analysis

Information and communication technologies are part of our day-to-day life in the execution of all activities, including health care. However, it is not known how much the use of technologies can contribute to the adoption of healthy lifestyle habits. Thus, the objective of this study was to analyze whether the use of information and communication technologies contributes to weight control among adults when compared to the traditional approach method. The search was performed in November 2021 in eight electronic databases in addition to gray literature bases. The quality of the studies was assessed using the Cochrane risk of bias tool. The standardized mean difference was used for the meta-analytic measurement using the random effects model using the Dersimonian-Laid method in the Stata statistical package version 17. The body mass index of the intervention group decreased by an average of 0.56 (95% CI: -0.83; -0.30) when compared to the control group. When comparing the before and after groups, the intervention group also had a greater reduction in BMI (summarized mean: -0.83; 95% CI: -1.40; -0.26). Information and communication technologies contribute to the reduction of the body mass index in the adult population when compared to the traditional model of monitoring.

Interventions to Promote Physical Activity and Healthy Digital Media Use in Children and Adolescents: A Systematic Review

OBJECTIVES

To identify effective interventions that promote healthy screen time use and reduce sedentary behavior in school-age children and adolescents (SACA) in all settings, over the last 20 years.

METHODS

Searches were conducted from 2000 until March 2021 using PubMed, Embase, Medline, PsycINFO, Ovid SP, The Cochrane Library, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register, and the WHO regional databases, including Google Scholar and reference lists of relevant articles and reviews. Randomized-controlled trials and quasi-experimental studies assessing interventions to reduce sedentary behaviors and screen time in healthy SACA (aged 5-19.9 years) globally. Data were extracted by 2 reviewers and where possible, pooled with a random-effects model.

RESULTS

The review included 51 studies, of which 23 were included in meta-analyses with 16 418 children and adolescents. Nondigital randomized-controlled trials reported a small, but significant reduction of TV-specific screen time (minutes per day) (mean difference, -12.46; 95% confidence interval, -20.82 to -4.10; moderate quality of evidence) and sedentary behavior (minutes per day) (mean difference, -3.86; 95% confidence interval, -6.30 to -1.41; participants = 8920; studies = 8; P = .002; moderate quality of evidence) as compared with control groups. For quasi-experimental studies, nondigital interventions may make little or no difference on screen time (minutes per day) or sedentary behavior (minutes per day), given the high uncertainty of evidence. Most studies were conducted in a high-income country. Generalizability of results to low- and middle- income countries remain limited.

CONCLUSIONS

Public health policies and programs will be necessary to reduce excessive sedentary behavior and screen time, especially in the post-coronavirus disease 2019 reality.

Digital Interventions for Universal Health Promotion in Children and Adolescents: A Systematic Review

BACKGROUND AND OBJECTIVES

Digital media has been used mostly to deliver clinical treatments and therapies; however limited evidence evaluates digital interventions for health promotion. The objective of this review is to identify digital interventions for universal health promotion in school-aged children and adolescents globally.

METHODS

Eligible articles were searched in PubMed, Embase, Medline, Ovid SP, The Cochrane Library, Cochrane Central Register of Controlled Trials, WHO regional databases, Google Scholar, and reference lists from 2000 to March 2021. Randomized controlled trials and quasi-experimental studies evaluating interventions that promote health in school-aged children and adolescents (5-19.9 years) were included. Methods were conducted in duplicate. Where possible, data were pooled with a random-effects model.

RESULTS

Seventy-four studies were included (46 998 participants), of which 37 were meta-analyzed (19 312 participants). Interventions increased fruit and vegetable consumption (servings per day) (mean difference [MD] 0.63, 95% confidence interval [CI] 0.21 to 1.04; studies = 6; P = .003; high quality of evidence), and probably reduced sedentary behavior (MD -19.62, 95% CI -36.60 to -2.65; studies = 6; P = .02; moderate quality of evidence), and body fat percentage (MD -0.35%, 95% CI -0.63 to -0.06; studies = 5; P = .02; low quality of evidence). The majority of studies were conducted in high-income countries and significant heterogeneity in design and methodology limit generalizability of results.

CONCLUSIONS

There is great potential in digital platforms for universal health promotion; however, more robust methods and study designs are necessitated. Continued research should assess factors that limit research and program implementation in low- to middle-income countries.

Digital Health Promotion and Prevention in Settings: Scoping Review

BACKGROUND

Digital technologies are increasingly integrating into people's daily living environments such as schools, sport clubs, and health care facilities. These settings play a crucial role for health promotion and prevention because they affect the health of their members, as the World Health Organization has declared. Implementing digital health promotion and prevention in settings offers the opportunity to reach specific target groups, lower the costs of implementation, and improve the health of the population. Currently, there is a lack of scientific evidence that reviews the research on digital health promotion and prevention in settings.

OBJECTIVE

This scoping review aims to provide an overview of research targeting digital health promotion and primary prevention in settings. It assesses the range of scientific literature regarding outcomes such as applied technology, targeted setting, and area of health promotion or prevention, as well as identifies research gaps.

METHODS

The scoping review was conducted following the Levac, Colquhoun, and O'Brien framework. We searched scientific databases and gray literature for articles on digital setting-based health promotion and prevention published from 2010 to January 2020. We included empirical and nonempirical publications in English or German and excluded secondary or tertiary prevention and health promotion at the workplace.

RESULTS

From 8888 records, the search resulted in 200 (2.25%) included publications. We identified a huge diversity of literature regarding digital setting-based health promotion and prevention. The variety of technology types extends from computer- and web-based programs to mobile devices (eg, smartphone apps) and telemonitoring devices (sensors). We found analog, digital, and blended settings in which digital health promotion and prevention takes place. The most frequent analog settings were schools (39/200, 19.5%) and neighborhoods or communities (24/200, 12%). Social media apps were also included because in some studies they were defined as a (digital) setting. They accounted for 31.5% (63/200) of the identified settings. The most commonly focused areas of health promotion and prevention were physical activity (81/200, 40.5%), nutrition (45/200, 22.5%), and sexual health (34/200, 17%). Most of the interventions combined several health promotion or prevention methods, including environmental change; providing information, social support, training, or incentives; and monitoring. Finally, we found that the articles mostly reported on behavioral rather than structural health promotion and prevention.

CONCLUSIONS

The research field of digital health promotion and prevention in settings is heterogeneous. At the same time, we identified research gaps regarding the absence of valid definitions of relevant terms (eg, digital settings) and the lack of literature on structural health promotion and prevention in settings. Therefore, it remains unclear how digital technologies can contribute to structural (or organizational) changes in settings. More research is needed to successfully implement digital technologies to achieve health promotion and prevention in settings.

Gender-Specific Determinants of eHealth Literacy: Results from an Adolescent Internet Behavior Survey in Taiwan

Adolescents' Internet health information usage has rarely been investigated. Adolescents seek all kinds of information from the Internet, including health information, which affects their Health Literacy that eHealth Literacy (eHL). This study is a retrospective observational study, we have total of 500 questionnaires were distributed, 87% of which were recovered, and we explored the channels that adolescents use to search for health information, their ability to identify false information, and factors affecting the type and content of health information queried. Adolescents believe that the Internet is a good means to seek health information because of its instant accessibility, frequent updating, convenience, and lack of time limits. More boys use the Internet to seek health information than girls in junior high schools (p = 0.009). The Internet is an important source of health information for adolescents but contains extensive misinformation that adolescents cannot identify. Additionally, adolescent boys and girls are interested in different health issues. Therefore, the government should implement measures to minimize misinformation on the Internet and create a healthy, educational online environment to promote Adolescents' eHealth Literacy (eHL).

IMPACT OF SOFTWARE FOR MOBILE DEVICES ON THE BEHAVIOR OF ADOLESCENTS IN OBESITY PREVENTION

ABSTRACT Objective: to analyze the impact of educational software on the behavior of adolescents about obesity prevention in two public schools of Divinópolis-MG. Method: uncontrolled clinical trial involving 238 adolescents, in the city of Divinópolis, MG, Brazil. Between June and October 2018, weight and height were measured, 24-hour dietary recall was performed, physical activity level was verified, socioeconomic classification and the stage of readiness for behavioral change was evaluated. The McNemar test was used to compare the qualitative variables. For the effect of the intervention on the quantitative variables, the Generalized Estimating Equations model was used. In the intervention, the educational game Healthy Running was used, developed for this study. Data were collected before and two months after the intervention. Results: among the participants, 62.6% are female, with a median age of 16.7 years, ranging from 15 to 19 years. Regarding the nutritional situation before the intervention, 18.5% had excess weight. As to the level of physical activity is concerned, 50.4% were classified as active. After the intervention, the z-score of body mass index for males showed a significant improvement (p<0.000), as well as the level of physical activity (p<0.001). Conclusion: the use of the educational game was valid and presented relevant results in improving the adolescents' behavior regarding food and physical activity. The use of the educational game can be considered appropriate to support education in the health area.
