“…Over the past two decades, there has been a dramatic increase in the Internet users (Internet Society 2017) and subsequently a rise also in the number of digital health interventions. The previous reviews have concluded that digital health interventions may have positive effects on outcomes such as PA and quality of life (Cotie et al 2018;Foster et al 2013;Geraedts et al 2013;Jahangiry et al 2017;Schäfer et al 2018), and among the unique advantages of these interventions are cost-efficiency, accessibility and convenience, including 24-h access to intervention material (Joseph et al 2014;Lewis et al 2010;Oh et al 2005;World Health Organization 2016). In light of this, digital tools (e.g., web-based or smart device applications) may be plausible for delivering wide-spread, effective and cost-efficient exercise interventions in a home-based setting.…”

Objectives We aimed to systematically review the potential benefits of digital exercise interventions for improving measures of central obesity including visceral adipose tissue (VAT) and anthropometric surrogates for VAT in overweight or centrally obese adults aged 18 or over. Methods A systematic literature search was conducted in three databases up until March 2020 (PROSPERO registration nr CRD42019126764). Results N = 5 studies including 438 participants (age 48-80) with body mass index C 25 kg/m 2 met the eligibility criteria and were included. The duration of the interventions ranged from 8 to 24 weeks. No study measured the primary outcome VAT, although in N = 4 studies, waist circumference (WC) decreased by between 1.3 and 5.6 cm in the intervention groups. Conclusions This systematic review shows that there is no evidence for the effects of digital exercise on VAT, although digital exercise may decrease WC. These findings highlight the need for additional randomized controlled trials to confirm the findings with respect to WC, and to further investigate the effects of digital exercise on VAT. Together, this may have important implications for reducing the burden of physical inactivity and obesity.

“…Many electronic health (eHealth) interventions have been assessed among physically and mentally ill patients (e.g., Dening et al 2019;Gao et al 2019). The American Psychological Association (2015) suggests that web-based interventions have become a popular and acceptable method of support and therapy around the world and the effectiveness of many of them has been presented in numerous publications (e.g., Jahangiry et al 2017;Ploeg et al 2018). The high prevalence of computer use provides novel possibilities for enhancing health service delivery (American Psychological Association 2015; Dening et al 2019).…”

The aims of this study were twofold: (1) to investigate the effectiveness of web-based psychoeducation for emotional functioning, eating behaviors, and body image among premenopausal women with excess body weight, and (2) to compare the efficacy of two types of web-based psychoeducation. Three hundred individuals were asked to volunteer in the present study. All participants were recruited in Poland from September 2017 to July 2019. Finally, a total of 129 premenopausal women took part in the research and signed informed consent. Their ages ranged between 18 and 48 years old (M = 32.28, SD = 7.65). Self-reported weight and height were recorded. BMI was calculated using self-reported data. Their average body mass index was 30.54 kg/m2 (SD = 3.69). In our randomized experiment, the participants were allocated into three groups: experimental group I (EG I, N = 43), experimental group II (EG II, N = 46), and wait list control group (CG, N = 40). Five questionnaires were included in the online survey at the baseline measurement (Day 0), at the end of psychoeducational intervention (Day 16) and 75 days from the start of the 15-day intervention (Day 76). Measurement tools included the Difficulties in Emotion Regulation Scale, the Positive and Negative Affect Schedule, the Mindful Eating Scale, the Three-Factor Eating Questionnaire, and the Body Attitude Test. Our eHealth web-based psychoeducation consisted of three modules: emotional functioning module (EG I: theoretically consistent approach (TCA) vs EG II: eclectic approach; EA), eating behaviors module (EG I, EG II: based on mindfulness-based eating training; MET), body image module (EG I, EG II: based on Cash’s prevention of body image disturbances; CPBID). The first experimental group (EG I) had intervention containing TCA, MET, and CPBID, while the second experimental group (EG II) EA, MET, and CPBID. According to between-group comparison, both types of web-based psychoeducation led to an increase in adaptive emotion regulation (Day 16: EG I vs CG: p < 0.001, EG II vs CG: p < 0.001; Day 76: EG I vs CG: p < 0.01, EG II vs CG: p < 0.001). In EG I, the intervention resulted in a higher reduction (than in CG) in emotional eating (Day 16: p < 0.01, Day 76: p < 0.01), uncontrolled eating (Day 16: p < 0.05, Day 76: p < 0.05), and negative appreciation of body size (Day 16: p < 0.01, Day 76: p < 0.01). In EG II, a lower level of emotional eating was found on Day 76 (EG II vs CG: p < 0.05). Two months after completion of the 15-day intervention, no statistically significant reduction for BMI was observed in either experimental group (p > 0.05). The effectiveness of both types of web-based psychoeducation was also confirmed in within-group comparison (Day 0 vs Day 16 and Day 0 vs Day 76). There was a significant increase in emotion regulation and mindful eating, as well as a decrease in emotional eating, uncontrolled eating, negative appreciation of body size, lack of familiarity with one’s body, and the experiencing of negative emotions in both experimental groups (EG I, EG II). Both types of web-based psychoeducation might have to be considered in creating future web-based psychoeducation among premenopausal women with excess body weight.

“…These are more costefficient and readily accessible [18][19][20] and therefore has the potential for wide-spread distribution of exercise interventions in home-based settings. Previous systematic reviews have described the positive effects of web-based physical activity interventions [21,22]. In conjunction with the increasing number of older internet-users during the past two decades [23,24], positive effects have been seen also in older people specifically [25,26].…”

Background: Visceral adipose tissue (VAT) is a strong risk factor for cardiovascular disease and increases with age. While supervised exercise (SE) may be an effective approach, web-based exercise (WE) have other advantages such as being more readily accessible. Therefore, we evaluated the effects of WE on VAT, body composition and cardiometabolic risk markers in centrally obese older adults and compared the effects of WE to SE. We also explored the feasibility of WE. Methods: In a randomized controlled trial conducted in Umeå, Sweden during January 2018-November 2018, N = 77, 70-year-old men and women with central obesity (> 1 kg VAT for women, > 2 kg for men) were randomized to an intervention group (n = 38) and a wait-list control group (n = 39). The intervention group received 10 weeks of SE while the wait-list control group lived as usual. Following a 10-week wash-out-period, the wait-list control group received 10 weeks of WE. The primary outcome was changes in VAT. Secondary outcomes included changes in fat mass (FM), lean body mass (LBM), blood lipids, fasting blood glucose. Additionally, we explored the feasibility of WE defined as adherence and participant experiences. Results: WE had no significant effect on VAT (P = 0.5), although it decreased FM by 450 g (95% confidence interval [CI], 37 to 836, P < 0.05). The adherence to WE was 85% and 87-97% of the participants rated aspects of the WE intervention > 4 on a scale of 1-5. Comparing SE to WE, there was no significant difference in decrease of VAT (Cohen's δ effect size [ES], 0.5, 95% CI, − 24 to 223, P = 0.11), although SE decreased FM by 619 g (ES, 0.5, 95% CI, 22 to 1215, P < 0.05) compared to WE. Conclusions: Ten weeks of vigorous WE is insufficient to decrease VAT in centrally obese older adults, but sufficient to decrease FM while preserving LBM. The high adherence and positive experiences of the WE intervention implies that it could serve as an alternative exercise strategy for older adults with central obesity, with increased availability for a larger population.
