Objective To systematically review the efficacy of short message intervention on glycosylated hemoglobin (HbAlc) and blood glucose levels on patients with type 2 diabetes mellitus. Methods We electronically searched databases including PubMed, EMbase, The Cochrane Library, CNKI and CBM from inception to August 2016, to collect randomized controlled trials (RCTs) about short message intervention in type 2 diabetes mellitus patients. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed using Stata 12.0 software. Results A total of 17 RCTs involving 2 879 patients were included. The results of meta-analysis showed that, on the basis of basic treatment, the use of text messages could lower the levels of HbA1c (SMD3 months=–0.50, 95%CI –0.67 to –0.34, P<0.001; SMD6 months=–0.33, 95%CI –0.59 to –0.07, P=0.012), FBG (SMD3 months=–0.28, 95%CI –0.45 to –0.11, P=0.001; SMD9 months=–0.99, 95%CI –1.44 to –0.54, P<0.001), PBG (SMD3 months=–0.99, 95%CI –1.54 to –0.44, P<0.001; SMD6 months=–0.81, 95%CI –1.25 to –0.36, P<0.001; SMD9 months=–0.78, 95%CI –1.23 to –0.34, P=0.001). Conclusion The current evidence shows that the use of SMS can improve glycosylated hemoglobin and blood glucose levels on type 2 diabetes patients. Due to limited quality and quantity of the included studies, the above conclusions are needed to be verified by more high quality studies.
Objective To systematically review the effectiveness of short message intervention on smoking cessation. Methods Databases including PubMed, The Cochrane Library, EMbase, CBM were searched from inception to August 2016, to collect randomized controlled trials (RCTs) about short message service (SMS) for smoking cessation. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed using Stata 12.0 software. Results A total of 14 RCTs involving 15 543 participants were included. The results of meta-analysis showed that, compared with the control group, no significant difference was found in self-reported three months continuous abstinence (RR=0.830, 95%CI 0.679 to 1.014, P=0.069), 30 day point quit rate (RR=0.878, 95%CI 0.687 to 1.122, P=0.076). However, there were significant differences in the self-reported 7-day point abstinence (RR=1.149, 95%CI 1.014 to 1.303, P=0.03), the CO biochemical verification abstinence (RR=0.571, 95%CI 0.357 to 0.914, P=0.020), and the average number of cigarettes smoked per day (SMD=–0.25, 95%CI –0.37 to –0.12, P<0.001). Conclusion The available evidence indicates that short message intervention has a better effect on short-term smoking cessation. Therefore, more long-term studies are needed to determine the association between SMS and quit smoking behavior.
