BACKGROUND Internet or mobile device use as a form of information and communication technology (ICT) can be more effective in weight loss and weight maintenance than traditional obesity interventions. OBJECTIVE The study aims to assess the effectiveness of child-centered ICT interventions on obesity-related outcomes. METHODS Articles were retrieved from the Cochrane Central Register of Controlled Trials, Embase, and PubMed web-based databases. We selected randomized controlled trials in which the participants were aged &lt;18 years. The primary outcomes were BMI, body weight, BMI <i>z</i>-score, waist circumference, and percentage body fat. RESULTS In total, 10 of the initial 14,867 studies identified in the databases were selected according to the inclusion criteria. A total of 640 participants were included in the intervention group and 619 in the comparator group. Meta-analyses were conducted considering various subgroups (intervention type, comparator type, target participants, mean age, sex, BMI status, and follow-up period). Overall, ICT interventions demonstrated no significant effect on BMI, body weight, BMI <i>z</i>-score, waist circumference, and percentage body fat. Subgroup analyses revealed that the effect of the intervention was statistically significant for the following: <i>web</i> intervention (weighted mean difference [WMD]=−1.26 kg/m<sup>2</sup>, 95% CI −2.24 to −0.28), <i>lifestyle modification</i> comparator (WMD=−1.75, 95% CI −2.76 to −0.74), intervention involving both <i>boys and girls</i> (WMD=−1.30, 95% CI −2.14 to −0.46), and intervention involving <i>obesity only</i> (WMD=−1.92, 95% CI −3.75 to −0.09). CONCLUSIONS The meta-analysis results for children with obesity who used the <i>web</i> intervention program confirmed significant effects on BMI reduction compared with <i>lifestyle modification</i>. Evidence from the meta-analysis identified internet technology as a useful tool for weight loss in children with obesity.

ABSTRACT Background The role of dietary fiber in obesity management remains debatable. Evidence suggests that intake of viscous fiber may have the potential to facilitate weight loss. Objective We aimed to summarize and quantify the effects of viscous fiber on body weight, BMI, waist circumference, and body fat, independent of calorie restriction, through a systematic review and meta-analysis of randomized controlled trials. Methods Trials ≥4 wk in duration that assessed the effect of viscous fiber supplemented to an ad libitum diet along with comparator diets were included. MEDLINE, EMBASE, and the Cochrane library were searched through 24 July, 2019. Two independent reviewers extracted relevant data. Data were pooled using the generic inverse variance method and random-effects models and expressed as mean differences with 95% CIs. Interstudy heterogeneity was assessed (Cochran Q statistic) and quantified (I2 statistic). The overall certainty of evidence was explored using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Results Findings from 62 trials (n = 3877) showed that viscous fiber reduced mean body weight (−0.33 kg; 95% CI: −0.51, −0.14 kg; P = 0.004), BMI (in kg/m2) (−0.28; 95% CI: −0.42, −0.14; P = 0.0001), and waist circumference (−0.63 cm; 95% CI: −1.11, −0.16 cm; P = 0.008), with no change in body fat (−0.78%; 95% CI: −1.56%, 0.00%; P = 0.05) when consumed with an ad libitum diet. Greater reductions in body weight were observed in overweight individuals and those with diabetes and metabolic syndrome. The certainty of evidence was graded moderate for body weight, high for waist circumference and body fat, and low for BMI. Conclusions Dietary viscous fiber modestly yet significantly improved body weight and other parameters of adiposity independently of calorie restriction. Future trials are warranted to address the inconsistency and imprecision identified through GRADE and to determine long-term weight-loss sustainability. This systematic review and meta-analysis was registered at clinicaltrials.gov as NCT03257449.

Background: The effect of soy products on the weight of overweight or obese people is controversial, so we aimed to conduct a systematic review and a meta-analysis of published randomized controlled trials to analyze whether supplementation with soy products can help them to lose weight. Methods: The relevant data before January 2019 in PubMed, Embase and Cochrane Library were searched. A random-effect model was adopted to calculate the weighted average difference of net changes of body weight, body mass index (BMI), body fat percentage, fat mass, waist circumference, etc. Results: A total of 22 trials (870 overweight or obese participants) were reflected in the present meta-analysis. Analysis showed that soy products significantly reduced body weight, BMI, body fat percent and waist circumference in overweight or obese Asian populations (−0.37 kg, P = 0.010; −0.27 kg/m2, P = 0.042; −0.36%, P = 0.032; −0.35 cm, P = 0.049) and more significant effects were observed in non-menopausal women reduced body weight (−0.59 kg, P = 0.041), BMI (−0.59, P = 0.041) and waist circumference (−0.59 cm, P = 0.041) in overweight or obese populations. Conclusion: This meta-analysis showed that soy products have weight loss effects, mainly due to soy protein, isoflavone and soy fiber.

BACKGROUND Although previous studies on information and communication technology (ICT)–based intervention on mental health among adolescents with depressive symptoms have already been combined in a number of systematic reviews, coherent information is still missing about interventions used, participants’ engagement of these interventions, and how these interventions work. OBJECTIVE We conducted a systematic review and meta-analysis of trials to describe the effectiveness of Web-based interventions to support adolescents with depression or depressive symptoms, anxiety, and stress. We also explored the content of the interventions, as there has previously been a lack of coherent understanding of the detailed content of the Web-based interventions for these purposes. METHODS We included parallel randomized controlled trials targeted at adolescents, or young people in the age range of 10 and 24 years, with symptoms or diagnoses of depression and anxiety. The interventions were from original studies aimed to support mental health among adolescents, and they were delivered via Web-based information and communication technology. RESULTS Out of 2087 records identified, 27 papers (22 studies) met the inclusion criteria. On the basis of a narrative analysis of 22 studies, a variety of Web-based interventions were found; the most commonly used intervention was based on cognitive behavioral therapy. Meta-analysis was further conducted with 15 studies (4979 participants). At the end of the intervention, a statistically significant improvement was found in the intervention group (10 studies) regarding depressive symptoms (P=.02, median 1.68, 95% CI 3.11-0.25) and after 6 months (3 studies; P=.01, median 1.78, 95% CI 3.20-0.37). Anxiety symptoms (8 studies; P<.001, median 1.47, 95% CI 2.36-0.59) and moods and feelings (2 studies; P=.04, median 5.55, 95% CI 10.88-0.22) improved as well in the Web-based intervention group, but there was no difference in stress scores. However, adolescents in the intervention group left the study early more often, both in short-term studies (11 studies; P=.007, median 1.31, 95% CI 1.08-1.58) and mid-term studies (3 studies; P=.02, median 1.65, 95% CI 1.09-2.49). We did not find any studies that had assessed the costs of the Web-based interventions. CONCLUSIONS Despite widely reported promises that information technology use is beneficial to adolescents with depression, the results of our review show only short-term effects on adolescents’ mental well-being, whereas long-term effects remain questionable because of the limited number of studies reviewed. Information about the economic benefits of Web-based interventions is still lacking. The quality of the studies, especially biases related to attrition rates and selective reporting, still needs serious attention.

The proliferation of new forms of information and communication technology (ICT) has inundated the learning patterns of students at all levels and particularly at higher education level. The efficacy of teaching the digital generation of learners without a firm grasp of how they learn is like embarking upon a perpetual journey. Invariably, today&rsquo;s students have been mesmerized by digital gadgets from a very small age and this experience calls for a technology integrated paradigm. Hence, the current study focuses on the influence of evolving technology in conceptualizing pedagogy and practice in higher education. It explores staff members&rsquo; technological know-how and how they are able to influence learning at a University in Fiji. An exploratory research design was selected and a survey consisting of Likert scale items was administered. Subsequently, SPSS Statistical software was used for data analytical and reporting purpose. Findings are discussed in collaboration with a robust meta-analysis of literature and they reveal that apart from resources, staff readiness, confidence and motivation play important function in ICT integrated learning. This paper proposes that staff members should use technology and technological gadgets to enhance digital literacy and numeracy that in turn, would create a digitally vibrant society.
