Lifestyle interventions for type 2 diabetes management among migrants and ethnic minorities living in industrialized countries: A systematic review and meta-analyses

The objective of this systematic review was to determine the effectiveness of lifestyle interventions to improve the management of type 2 diabetes mellitus (T2DM) among migrants and ethnic minorities. Major searched databases included MEDLINE (via PubMed), EMBASE (via Ovid) and CINAHL. The selection of studies and data extraction followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. In the meta-analysis, significant heterogeneity was detected among the studies (I 2 >50%), and hence a random effects model was used. Subgroup analyses were performed to compare the effect of lifestyle interventions according to intervention approaches (peer-led vs community health workers (CHWs)-led). A total of 17 studies were included in this review which used interventions delivered by CHWs or peer supporters or combination of both. The majority of the studies assessed effectiveness of key primary (hemoglobin (HbA1c), lipids, fasting plasma glucose) and secondary outcomes (weight, body mass index, blood pressure, physical activity, alcohol consumption, tobacco smoking, food habits and healthcare utilization). Meta-analyses showed lifestyle interventions were associated with a small but statistically significant reduction in HbA1c level (-0.18%; 95% CI-0.32% to-0.04%, p=0.031). In subgroup analyses, the peer-led interventions showed relatively better HbA1c improvement than CHW-led interventions, but the difference was not statistically significant (p=0.379). Seven studies presented intervention costs, which ranged from US$131 to US$461 per participant per year. We conclude that lifestyle interventions using either CHWs or peer supporters or a combination of both have shown modest effectiveness for T2DM management among migrants of different background and origin and ethnic minorities. The evidence base is promising in terms of developing culturally appropriate, clinically sound and cost-effective intervention approaches to respond to the growing and diverse migrants and ethnic minorities affected by diabetes worldwide

Community health workers for non-communicable disease prevention and control in Nepal: A qualitative study

© Background/objective The increasing burden of non-communicable diseases (NCDs) in Nepal underscores the importance of strengthening primary healthcare systems to deliver efficient care. In this study, we examined the barriers and facilitators to engaging community health workers (CHWs) for NCDs prevention and control in Nepal. Design We used multiple approaches including (a) review of relevant literature, (b) key personnel and stakeholders' consultation meetings and (c) qualitative data collection using semistructured interviews. A grounded theory approach was used for qualitative data collection and the data were analysed thematically. Setting Data were collected from health facilities across four districts in Nepal and two stakeholder consultative meetings were conducted at central level. Participants We conducted in-depth interviews with CHWs (Health Assistants, Auxiliary Health Workers, Auxiliary Nurse Midwife) (n=5); key informant interviews with health policymakers/managers (n=3) and focus group discussions (FGDs) with CHWs (four FGDs; total n=27). Participants in two stakeholder consultative meetings included members from the government (n=8), non-government organisations (n=7), private sector (n=3) and universities (n=6). Results The CHWs were engaged in a wide range of public health programmes and they also deliver NCDs specific programmes such as common NCDs screening, provisional diagnosis, primary care, health education and counselling, basic medication and referral and so on. These NCD prevention and control services are concentrated in those districts, where the WHO, Package for prevention and control of NCDs) program is being implemented. Some challenges and barriers were identified, including inadequate NCD training, high workload, poor system-level support, inadequate remuneration, inadequate supply of logistics and drugs. The facilitating factors included government priority, formation of NCD-related policies, community support systems, social prestige and staff motivation. Conclusion Engaging CHWs has been considered as key driver to delivering NCDs related services in Nepal. Effective integration of CHWs within the primary care system is essential for CHW's capacity buildings, necessary supervisory arrangements, supply of logistics and medications and setting up effective recording and reporting systems for prevention and control of NCDs in Nepal
