E-health is regarded as a strategic tool to achieve a human-oriented integrated service model. This study introduced the e-health framework of the World Health Organization, and conducted a comparative study of the different e-health development characteristics in the United Kingdom, United States, Australia, Canada and other countries. Based on the results, we analyzed the practical problems in e-health development in China, and suggested possible policy approaches for strategies of e-health development to support the policy of e-health development in China.
ObjectiveTo systematically review the impact of different electronic health technologies on weight loss outcomes in overweight and simple obesity populations. MethodsThe Cochrane Library, Embase, PubMed and WOS databases were electronically searched to collect randomized controlled trials (RCTs) related to the objectives from inception to May 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.4 and Stata 18 software. ResultsA total of 9 RCTs involving 2 416 patients with overweight or simple obesity were included. The meta-analysis results showed that body weight (MD=?0.81, 95%CI ?1.1 to ?0.52, P<0.001), BMI (MD=?0.63, 95%CI ?0.89 to ?0.37, P<0.001), waist circumference (MD=?1.06, 95%CI ?1.70 to ?0.42, P<0.001) and energy intake (SMD=?0.44, 95%CI ?0.75 to ?0.13, P=0.005) in the e-health technology group were significantly improved compared with the control group. But there was no statistically significant difference in physical activity between two groups. ConclusionThe available evidence suggests that e-health technology is an effective tool for weight loss. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
