Recent advances in mobile technologies have provided an opportunity to disseminate health information on a variety of health conditions. Randomized controlled trials (RCTs) have shown that text messaging helps people to lose weight, but the effectiveness of interventions varies between studies. Thus, this review aimed to (1) identify RCTs that used text messages for overweight management, (2) identify components of the interventions, and (3) test their effectiveness. PubMed, Web of Science, ProQuest, and Scopus databases were searched to identify relevant studies.Quality scores for selected articles were assessed using the Joanna Briggs Institute (JBI) critical appraisal tools for interventional studies. The effectiveness of the interventions was tested using random effect models. Twelve studies that met inclusion criteria were included in this review. Ten of the included studies reported that text message interventions had a significant effect on weight loss. The pooled mean difference in body mass index (BMI) change after the intervention was À0.43 kg/m 2 (95% confidence interval, À 0.63 to -0.23 kg/m 2 ). Synthesis of the included studies provides evidence that (1) regular text messages; (2) interventions targeting weight monitoring, diet habit, and physical activity; and (3) the use of behavior change techniques led to significant weight loss.

ObjectivesNon-communicable diseases (NCDs) are causing a new and yetsignificant health challenge in low-income countries. In Ethiopia, although 39% of deaths are NCD related, the health system remains underprepared, highlighting the clear need for evidence on risk factor distributions to inform resource planning and the health response. Therefore, this review investigates prevalence distributions and sex and age variations of metabolic risk factors among Ethiopian adults.Research design and methodsThis systematic review used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies published until 6 January 2021 were searched from PubMed, Scopus, ProQuest and Web of Science databases, reference lists of selected studies and grey literature. Studies reporting prevalence of metabolic risk factors: overweight/obesity, hypertension, impaired glucose homoeostasis and metabolic syndrome among Ethiopian adults were eligible for this systematic review and meta-analysis. Two authors independently extracted data and used the Joanna Briggs Institute tool for quality appraisal. The random effects model was used to conduct meta-analysis using Stata V.16. Subgroup analyses examined prevalence differences by region, study year, sample size and settings.ResultsFrom 6087 records, 74 studies including 104 382 participants were included. Most showed high prevalence of metabolic risk factors. Meta-analysis revealed pooled prevalence of metabolic risk factors from 12% to 24% with the highest prevalence observed for overweight/obesity (23.9%, 95% CI 19.9% to 28.0%) and hypertension (21.1%, 95% CI 18.7% to 23.5%), followed by metabolic syndrome (14.7%, 95% CI 9.8% to 19.6%) and impaired glucose tolerance (12.4%, 95% CI 8.7% to 16.1%). The prevalence of overweight/obesity was higher in women. All metabolic risk factors were higher among people aged above 45 years.ConclusionsA signficant proportion of Ethiopian adults have at least one metabolic risk factor for NCDs. Despite heterogeneity of studies limiting the certainty of evidence, the result suggests the need for coordinated effort among policymakers, healthcare providers, non-governmental stakeholders and the community to implement appropriate preventive measures to reduce these factors.

Objective Ethiopia, like other developing countries, is going through an epidemiological transition, and high rates of non-communicable diseases (NCDs) are having a significant impact on the health system; however, there is limited evidence about community level NCD prevalence, multimorbidity, and population awareness that could inform targeted interventions and policy responses. This study aimed to identify factors associated with NCD prevalence, multimorbidity, and population awareness of NCDs in Bahir Dar, Northwest Ethiopia. Methods A community-based cross-sectional survey was conducted with 417 randomly sampled adults. We performed descriptive and logistic regression analyses to evaluate associations between NCD prevalence (cardiovascular diseases, diabetes, cancer, chronic respiratory diseases, chronic kidney disease, and hypertension) multimorbidity (2 or more NCDs) and demographic, socioeconomic, individual risk factors, anthropometrics, knowledge, and attitude. Results This study reveals that 24% of participating adults have an NCD, and 8% have multimorbidity. One-third (34.5%) have some NCD knowledge, and 75% consider NCDs more dangerous than communicable diseases. We find low NCD prevalence in participants: younger than 40 years of age (AOR 0.17, 95% CI 0.07 to 0.39); with normal body mass index (AOR 0.27, 0.10 to 0.77) and; with a family history of NCD (AOR 7.7, 4.2 to 14.1). Multimorbidity is lower in young adults (AOR 0.08, 0.03 to 0.26). NCD knowledge is higher in men (AOR 1.76, 1.06 to 2.93) and employed adults (AOR 2.91, 1.52 to 5.57), and NCD attitude in normal-weight adults (AOR 3.23, 1.42 to 7.39). Conclusion This study reveals a high prevalence of NCD and overall low NCD awareness in the population. Age above 40 years, family history of NCD, and weight in the obese category are significant predictors of NCD prevalence. These findings can help health professionals, health offices, and concerned stakeholders to plan targeted health interventions to reduce NCDs in the population.
