Dietary Intake and Nutritional Status among Refugees in Host Countries: A Systematic Review.

Refugees remain vulnerable to acute food insecurity, malnutrition, and critically inadequate food and nutrient intake after migration, regardless of the economic level of the host country. We conducted this systematic review to summarize and evaluate the dietary intake and nutritional status among refugees resettled in non-camp settings worldwide. We searched PubMed and Web of Science databases to review relevant studies published between 2009 and 2020 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We also conducted an additional manual search through PubMed and Google Scholar. Studies that evaluated both dietary intake and nutritional status of refugees in host countries were included. A total of 15 articles from 10 countries were included and assessed for study quality and outcomes. Poor dietary diversity and insufficient intake of specific food groups were reported. In addition to these dietary patterns, a high prevalence of stunting, underweight, and anemia was reported, particularly among children. A double burden of malnutrition was also observed across and within studies. Post-resettlement dietary intake and nutritional status of refugees are both influenced by factors at the pre- and post-resettlement stages as refugees transition to their host countries. Those factors, including pre-resettlement experiences, host country resources, socioeconomic status, acculturation, and food security, were summarized and presented in a conceptual model. There is a need for comprehensive dietary and health screening as well as culturally appropriate and sustainable nutrition education resources and interventions for refugees to improve their diet and nutrition. Longitudinal studies and novel methodological approaches are also suggested to measure changes in refugees' food intake and nutritional status as well as to further investigate factors associated with these 2 components.

Effectiveness of Mobile Health Interventions on Diabetes and Obesity Treatment and Management: Systematic Review of Systematic Reviews.

BACKGROUND: Diabetes and obesity have become epidemics and costly chronic diseases. The impact of mobile health (mHealth) interventions on diabetes and obesity management is promising; however, studies showed varied results in the efficacy of mHealth interventions. OBJECTIVE: This review aimed to evaluate the effectiveness of mHealth interventions for diabetes and obesity treatment and management on the basis of evidence reported in reviews and meta-analyses and to provide recommendations for future interventions and research. METHODS: We systematically searched the PubMed, IEEE Xplore Digital Library, and Cochrane databases for systematic reviews published between January 1, 2005, and October 1, 2019. We analyzed 17 reviews, which assessed 55,604 original intervention studies, that met the inclusion criteria. Of those, 6 reviews were included in our meta-analysis. RESULTS: The reviews primarily focused on the use of mobile apps and text messaging and the self-monitoring and management function of mHealth programs in patients with diabetes and obesity. All reviews examined changes in biomarkers, and some reviews assessed treatment adherence (n=7) and health behaviors (n=9). Although the effectiveness of mHealth interventions varied widely by study, all reviews concluded that mHealth was a feasible option and had the potential for improving patient health when compared with standard care, especially for glycemic control (-0.3% to -0.5% greater reduction in hemoglobin A1c) and weight reduction (-1.0 kg to -2.4 kg body weight). Overall, the existing 6 meta-analysis studies showed pooled favorable effects of these mHealth interventions (-0.79, 95% CI -1.17 to -0.42; I2=90.5). CONCLUSIONS: mHealth interventions are promising, but there is limited evidence about their effectiveness in glycemic control and weight reduction. Future research to develop evidence-based mHealth strategies should use valid measures and rigorous study designs. To enhance the effectiveness of mHealth interventions, future studies are warranted for the optimal formats and the frequency of contacting patients, better tailoring of messages, and enhancing usability, which places a greater emphasis on maintaining effectiveness over time.

A Systematic Examination of the Association between Parental and Child Obesity across Countries.

Childhood obesity has become a global epidemic. Parents can have an important influence on their children's health behaviors and weight status. Many studies have examined the association between parental and childhood weight status. However, much heterogeneity between studies exists, and the parent-child (P-C) association in obesity has varied. The purpose of this systematic examination and meta-analysis was to examine the strength and variation of the P-C association in obesity and to identify factors (e.g., demographic characteristics and country's economic level) that may influence this association. PubMed was searched for relevant studies published between January 2000 and July 2015. Thirty-two studies from 21 countries met inclusion criteria; 27 reported ORs for the P-C obesity association and were included in a meta-analysis. The meta-analysis showed a strong P-C obesity association (pooled OR: 2.22; 95% CI: 2.09, 2.36), which varied by type of P-C pair (i.e., parents-child, father-child, and mother-child), child age, parent and child weight status, and the country's economic level. Stronger associations were shown in older children than in younger children (ß ± SE: 0.02 ± 0.01), in both parents than in father only (ß ± SE: 0.51 ± 0.11) or mother only (ß ± SE: 0.38 ± 0.11), in parental obesity (ß ± SE: 0.26 ± 0.10) and child obesity (ß ± SE: 0.28 ± 0.12) than in parental and child overweight, and in high- than in middle-income countries (ß ± SE: 0.23 ± 0.08). Thus, research from multiple countries shows significant P-C associations in weight status, but this association varies by child age, type of P-C pair, weight status, and the country's economic level. Results suggest that families and parents should be a key target for obesity intervention efforts.

The Impact of Operating Room Noise Upon Communication During Percutaneous Nephrostolithotomy.

OBJECTIVE: Equipment and personnel contribute to the overall noise level in the operating room (OR). This study aims to determine intraoperative noise levels during percutaneous nephrostolithotomy (PCNL) and the effects of this noise upon intraoperative communication. METHODS: A PCNL benchtop model was used to measure intraoperative noise and determine its effect upon communication in three progressively increasing sound environments (baseline ambient noise, ambient noise with PCNL equipment, and ambient noise with both PCNL equipment and music). Five trials with 20 different medical words/phrases were spoken by the surgeon and responses were recorded by the first assistant, anesthesiologist, and circulating nurse. In addition, noise levels during PCNL were compared to common environmental noise levels. RESULTS: In the bench top model, noise levels were 53.49 A-weighted decibels (dBA) with ambient noise, 78.79 dBA with equipment in use, and 81.78 dBA with equipment and music. At the ambient noise level, the first assistant, anesthesiologist, and circulator correctly recorded 100%, 100%, and 96% of the words, respectively. The correct response rate by the subjects decreased to 97% (p = 0.208), 81% (p = 0.012), and 56% (p < 0.001) upon addition of PCNL equipment, and 90% (p = 0.022), 48% (p = 0.002), and 13% (p < 0.001) upon addition of music and PCNL equipment in the first assistant, anesthesiologist, and circulator, respectively. In the simulated OR model, PCNL noise level (81.78 dBA) was comparable to a passing freight train at 30 feet (82.2 dBA, p = 0.44). CONCLUSION: Noise pollution decreases effective intraoperative communication during PCNL. It is important for surgeons to understand the effect noise can have on attempted communication to prevent errors due to miscommunication. In addition, methods to decrease intraoperative noise pollution and improve communication in the OR could improve patient safety and outcomes.

A Systematic Examination of Food Intake and Adaptation to the Food Environment by Refugees Settled in the United States.

The United States is the largest refugee resettlement country in the world. Refugees may face health-related challenges after resettlement in the United States, including higher rates of chronic diseases due to problems such as language barriers and difficulty adapting to new food environments. However, reported refugee diet challenges varied, and no systematic examination has been reported. This study examined refugee food intake pre- and postresettlement in the United States and differences in intake across various refugee groups. We systematically reviewed relevant studies that reported on refugee food intake and adaptation to the US food environment. We searched PubMed for literature published between January 1985 and April 2015, including cross-sectional and prospective studies. Eighteen studies met inclusion criteria. Limited research has been conducted, and most studies were based on small convenience samples. In general, refugees increased meat and egg consumption after resettling in the United States. Changes in refugee intake of vegetables, fruits, and dairy products varied by socioeconomic status, food insecurity, past food deprivation experience, length of stay in the United States, region of origin, and age. South Asians were more likely to maintain traditional diets, and increased age was associated with more conservative and traditional diets. Despite the abundance of food in the United States, postresettlement refugees reported difficulty in finding familiar or healthy foods. More research with larger samples and follow-up data are needed to study how refugees adapt to the US food environment and what factors may influence their food- and health-related outcomes. The work could inform future interventions to promote healthy eating and living among refugees and help to reduce health disparities.
