A systematic review of recruitment and retention of ethnic minorities and migrants in obesity prevention randomised controlled trials.

BACKGROUND: Participants' recruitment and retention into community-based interventions can be challenging, especially in research involving ethnic minorities and migrants. Despite known challenges, there are limited reviews that probe recruitment and retention strategies involving ethnic minorities and migrants in the Organisation for Economic Cooperation and Development (OECD) countries. This systematic review aimed to measure recruitment and retention rates and identify the barriers and facilitators to effective recruitment and retention of ethnic minorities and migrants in community-based obesity prevention Randomised Control Trials (RCTs) in OECD countries. METHODS: This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five databases (CINAHL, Cochrane, Embase, Medline and PsychInfo) were searched from January 2000 to March 2022, in addition to Google and Google Scholar. Methodological quality and risk of bias were assessed, and pooled analysis and meta-ethnographic analysis were conducted on the included studies. RESULTS: Twenty-five studies were included in the review. The pooled analysis found a 64% rate of recruitment of ethnic minorities in RCTs, with a retention rate of 71%. Key facilitators identified were-use of multiple communication channels, incentives, recruiting community champions, participant convenience and employing culturally sensitive strategies. Key barriers to participation were limited access to study sites, time constraints, limited trust, perceived fear, and anxiety. CONCLUSION: Findings suggest the importance of undertaking culturally appropriate recruitment and retention strategies to minimise barriers and facilitate effective recruitment and retention of low-income ethnic minorities and migrants in community-based research.

Rural and urban differences in the prevalence and determinants of Type-2 diabetes in Bangladesh.

OBJECTIVE: To estimate the prevalence of Type 2 Diabetes (T2D) in urban and rural settings and identify the specific risk factors for each location. METHOD: We conducted this study using data from the 2017-18 Bangladesh Demographic and Health Survey (BDHS), sourced from the DHS website. The survey employed a stratified two-stage sampling method, which included 7,658 women and 7,048 men aged 18 and older who had their blood glucose levels measured. We utilized chi-square tests and ordinal logistic regression to analyze the association between various selected variables in both urban and rural settings and their relationship with diabetes and prediabetes. RESULTS: The prevalence of T2D was 10.8% in urban areas and 7.4% in rural areas, while pre-diabetes affected 31.4% and 27% of the populations in these respective settings. The study found significant factors influencing diabetes in both urban and rural regions, particularly in the 55-64 age group (Urban: AOR = 1.88, 95% CI [1.46, 2.42]; Rural: AOR = 1.87, 95% CI [1.54, 2.27]). Highly educated individuals had lower odds of T2D, while wealthier and overweight participants had higher odds in both areas. In rural regions, T2D risk was higher among caffeinated drink consumers and those not engaged in occupation-related physical activity, while these factors did not show significant influence in urban areas. Furthermore, urban participants displayed a significant association between T2D and hypertension. CONCLUSION: Our study outlines a comprehensive strategy to combat the increasing prevalence of T2D in both urban and rural areas. It includes promoting healthier diets to control BMI level, encouraging regular physical activity, early detection through health check-ups, tailored awareness campaigns, improving healthcare access in rural regions, stress management in urban areas, community involvement, healthcare professional training, policy advocacy like sugary drink taxation, research, and monitoring interventions. These measures collectively address the T2D challenge while accommodating the distinct features of urban and rural settings.

Promotion of livelihood opportunities to address food insecurity in Rohingya refugee camps of Bangladesh.

The world is facing a tremendous problem in the form of food insecurity that is posing a great challenge to achieving sustainable development goal 2 of creating a hunger-free world. Refugees and displaced populations are particularly vulnerable to food insecurity and malnutrition, who lack any productive assets and depend on aid. Rohingya refugees, displaced from Myanmar and took refuge in Cox's Bazar, Bangladesh, live in a crowded unhealthy environment and are severely vulnerable to food insecurity and malnutrition. In our recent study, we found that only 21.6% of the households in Rohingya refugee camps had acceptable food security status. Interestingly, this study further revealed that acceptable food security status was significantly higher among the households that had some additional income aside from aid, compared to those relying on aid alone. This shows the importance of promoting livelihood opportunities to improve food security status among the camp dwellers. In this paper, we presented our views on promoting livelihood opportunities to address the overwhelming food insecurity crisis among the Rohingya refugees in Bangladesh.

Assessment of mental well-being and its socio-economic determinants among older adults in the Rohingya refugee camp of Bangladesh.

Older adults residing in refugee settlements with unhealthy living environments, inadequate access to health care services, and limited psychosocial support are vulnerable to experience mental health problems jeopardizing their mental well-being. The present study aims to explore the mental well-being status and its socio-economic determinants among the older adults living in the Rohingya refugee camp in Bangladesh. This cross-sectional study was conducted among adults aged ≥ 60 residing in five sub-camps within the Rohingya refugee camp of Cox's Bazar, Bangladesh. Data were collected through face-to-face interviews conducted between November and December 2021. The 14-item Warwick-Edinburgh Mental Well-being Scale was used to assess mental well-being. A cumulated score was derived using the scale ranging from 14 to 70, with higher scores indicating greater levels of mental well-being. A generalized linear regression model was used to examine the socio-economic factors associated with the mental well-being of older adults. A total of 864 older adults participated in the study having a mean mental well-being score of 45.4. Regression analysis revealed that the difference in the logs of mental well-being score was expected to be significantly lower among participants aged 70-79 years (ß: - 1.661; 95% CI: - 2.750 to - 0.572; p = 0.003), aged ≥ 80 years (ß: - 3.198; 95% CI: - 5.114 to - 1.282; p = 0.001), and those with any non-communicable chronic conditions (ß: - 2.903; 95% CI: - 3.833 to - 1.974; p < 0.001) when compared to their counterparts. Conversely, the difference in the logs of mental well-being score was expected to be significantly higher among individuals with formal schooling (ß: 3.370, 95% CI: 1.855 to 4.886, p < 0.001) and those having additional income besides aid (ß: 1.629; 95% CI: 0.642 to 2.615; p = 0.001), compared to their respective counterparts. Our findings highlight the need to provide psychosocial assistance to older individuals, particularly those who live in large families, suffer from chronic diseases, and live in socio-economic deprivation.
