Social network enhanced behavioral interventions for diabetes and obesity: A 3 arm randomized trial with 2 years follow-up in Jordan.

While obesity and diabetes are rising pandemics, few low-cost and effective prevention and management strategies exist, especially in the Middle East. Nearly 20% of adults in Jordan suffer from diabetes, and over 75% are overweight or obese. Social network-based programs have shown promise as a viable public health intervention strategy to address these growing crises. We evaluated the effectiveness of the Microclinic Program (MCP) via a 6-month multi-community randomized trial in Jordan, with follow-up at 2 years. The MCP leverages existing social relationships to propagate positive health behaviors and information. We recruited participants from 3 community health centers in Amman, Jordan. Participants were eligible for the study if they had diabetes, pre-diabetes, or possessed ≥1 metabolic risk factor along with a family history of diabetes. We randomized participants into three trial arms: (A Group) received the Full MCP with curriculum-activated social network interactions; (B Group) received Basic MCP educational sessions with organic social network interactions; or (C Group-Control) received standard care coupled with active monitoring and parallel screenings. Groups of individuals were randomized as units in a 3:1:1 ratio, with resulting group sizes of n = 540, 186, and 188 in arms A, B, and C, respectively. We assessed the overall changes in body weight, fasting glucose, hemoglobin A1c (HbA1c) and mean arterial blood pressure between study arms in multiple evaluations across 2 years (including at 6-months and 2-years follow-up). We investigated the effectiveness of Full and Basic MCP social network interventions using multilevel models for longitudinal data with hierarchical nesting of individuals within MCP classrooms, within community centers, and within temporal cohorts. We observed significant overall 2-year differences between all 3 groups for changes in body weight (P = 0.0003), fasting blood glucose (P = 0.0015), and HbA1c (P = 0.0004), but not in mean arterial blood pressure (P = 0.45). However, significant changes in mean arterial pressure were observed for Full MCP versus controls (P = 0.002). Weight loss in the Full MCP exceeded (-0.97 kg (P<0.001)) the Basic MCP during the intervention. Furthermore, both Full and Basic MCP yielded greater weight loss compared to the control group at 2 years. The Full MCP also sustained a superior fasting glucose change over 2 years (overall P<0.0001) versus the control group. For HbA1c, the Full MCP similarly led to greater 6-month reduction in HbA1c versus the control group (P<0.001), with attenuation at 2 years. For mean arterial blood pressure, the Full MCP yielded a greater drop in blood pressure versus control at 6 months; with attenuation at 2 years. These results suggest that activated social networks of classroom interactions can be harnessed to improve health behaviors related to obesity and diabetes. Future studies should investigate how public health policies and initiatives can further leverage social network programs for greater community propagation. Trial registration.

Ramadan fasting and weight change trajectories: Time-varying association of weight during and after Ramadan in low-income and refugee populations.

Obesity is a significant driver of the global burden of non-communicable diseases. Fasting is one approach that has been shown to improve health outcomes. However, the effects of Ramadan fasting differ in that the type, frequency, quantity, and time of food consumption vary. This phenomenon requires in-depth evaluation considering that 90% of Muslims (~2 billion people) fast during Ramadan. To address this issue, we evaluated the pattern of weight change during and following Ramadan for a total of 52 weeks. The study was conducted in Amman, Jordan. Between 2012 and 2015, 913 participants were recruited as part of a trial investigating the efficacy of a weight loss intervention among those with or at risk for diabetes. Weight was measured weekly starting at the beginning of Ramadan, and changes were analyzed using discrete and spline models adjusted for age, sex, and trial group. Results show slight weight gain within the first two weeks and weight loss in the subsequent weeks. During the first week of Ramadan, the estimate for a weight increase was 0·427 kg, (95% CI: -0·007, 0·861) relative to baseline, compared to an estimated weight reduction of 0·55kg (95% CI: 0·05, 1·05) by the 8th week relative to baseline. There was clear evidence of gradual weight gain from week 8 until week 26 with an estimated weight gain of 2.547 kg (95% CI: 1.567, 3.527) at week 26 relative to baseline. A sharp drop of 2.66kg in weight was observed between the 26th and 28th week before it stabilized. Our results show that weight changes occurred during and after Ramadan. Weight fluctuations may affect health risks, and thus, findings from this study can inform interventions. Public health agencies could leverage this period of dietary change to sustain some of the benefits of fasting. The authors (DEZ, EFD) acknowledge the Mulago Foundation, the Horace W.

An integrated physical and mental health awareness education intervention to reduce non-communicable diseases among Syrian refugees and Jordanians in host communities: A natural experiment study.

The Syrian crisis has had a devastating impact on displaced populations and among host communities in neighboring countries such as Jordan. Many of these individuals are at risk for non-communicable diseases (NCD) and mental health disorders, yet do not have access to services designed to manage or prevent these conditions. The purpose of this study was to examine the efficacy of a non-communicable disease (NCD) awareness educational intervention and an integrated NCD and mental health education intervention on reducing cardiovascular disease (CVD) risk among Jordanians and displaced Syrians. This natural experiment study was conducted in three health centers in Irbid, Jordan with 213 Syrian participants and 382 Jordanians. Participants were assigned to one of three study conditions: the Healthy Community Clinic (HCC), a non-communicable disease educational intervention; the HCC with added mental health awareness sessions; standard healthcare. CVD risk factors were assessed at baseline, 12 and 18 months. The HCC education group yielded significant improvements in three CVD risk factors including: body mass index (BMI) -1.91 (95% CI: -2.09, -1.73); systolic blood pressure (SBP) -12.80 mmHg (95% CI: -16.35, -9.25); and diastolic blood pressure (DBP) -5.78 mmHg (95% CI: -7.96, -3.60) compared to standard care. The HCC-mental health treatment arm also demonstrated significant improvements in BMI, SBP, and DBP compared to standard care. Significant improvements in fasting blood glucose -20.32 (CI: -28.87, -11.77) and HbA1c -0.43 (-0.62, -0.24) were also illustrated in the HCC-mental health treatment arm. The HCC-mental health group sustained greater reductions in CVD risk than the HCC education group at 18-months. This study is among the first to our knowledge illustrating an integrated health and mental health educational intervention can reduce CVD risk among Syrian refugees and Jordanians. Continued investment and research in CVD prevention interventions is needed to enhance health, reduce costs, and have lasting benefits for conflict-affected individuals and communities.

A social-network behavioral health program on sustained long-term body weight and glycemic outcomes: 2-year follow-up of a 4-month Microclinic Health Program in Jordan.

The burden of chronic diseases like diabetes and obesity is rapidly increasing in low and lower-middle income countries. This work assesses the long-term efficacy of a social-network based community health program for the management and prevention of type 2 diabetes. METHODS: The 4-month Microclinic Social Network Behavioral Health Program in Jordan (J-MCP) was an intervention for obesity and diabetes prevention and management conducted in the Kingdom of Jordan. Weight and HbA1c were collected at baseline, end of the 4-month program, and then 12 and 24 months after baseline. Multi-level longitudinal repeated measures analysis estimated the long-term change in metabolic outcomes, and estimated the intra-class correlations (ICCs) for assessing the degree of clustering that different social network levels, of microclinic group vs. classroom group vs. clinic geographic location vs. cohort temporal wave, contributed to body weight and glycemic changes. RESULTS: Of 315 participants, 83.2% completed the J-MCP program, with 90% followup at 12-months, and 70% at 24-months. At the end of the 4-month program, participants experienced a -2.8 kg (95% CI: -3.6 to -2.1) mean body weight decrease, a corresponding -1.1 kg/m2 (-1.3 to -0.8) BMI decrease, and a -0.5% reduction in HbA1c (-0.6 to -0.3). At year 1, we observed significant mean weight reduction of -1.8 kg (-2.7 to -0.9), a corresponding -0.7 kg/m2 (-1.0 to -0.4) reduction in BMI, as well as a -0.4% (-0.6 to -0.3) sustained reduction in HbA1c. At 2 years, participants sustained mean weight loss of -1.6 kg (-2.6 to -0.5), a -0.42 kg/m2 (-0.8 to -0.04) reduction in BMI, and an absolute -1.0% (-1.1 to -0.8) sustained reduction in HbA1c. Analyzing different social network levels, classroom group explained ~50% of total clustering of total weight loss and 22% of HbA1c trajectories during the short 4 month intervention. However, during 12 and 24 month followup, microclinic social group clustering explained ~75% to 92% of long-term weight loss trajectories, and 55% of long-term HbA1c trajectories. The pattern of 1-2 year sustainability of the weight and HbA1c decreases was largely attributed to the microclinic social network clusters. CONCLUSION: Results demonstrate that the 4-month J-MCP behavioral intervention yielded important 2-year sustained weight and HbA1c reductions, which were mostly attributed to microclinic social groups.

A descriptive survey of the different management practices for peripheral IV catheters among Greek, Jordanian, and Australian teaching hospitals.

Peripheral IV catheters (PIVCs) are commonly placed in hospital patients. However, there is a lack of evidence on which to base this practice. The aim of this study was to assess current knowledge and practice for this procedure in 3 different cultures. The study collected information from a postal questionnaire sent to physicians and nurses in teaching hospitals in Greece, Jordan, and Australia. The results gathered from the questionnaire depict a number of misconceptions with regard to the management of PIVCs in the 3 healthcare organizations selected for the study.

Anticoagulation period in idiopathic venous thromboembolism. How long is enough?

OBJECTIVE: The period of anticoagulation of a first episode of idiopathic venous thromboembolism has been 6 months. It is unclear if such patients would benefit from longer treatment, as there appears to be an increased risk of recurrence after anticoagulation is stopped. METHODS: In a randomized prospective study of 64 patients admitted to King Hussein Medical city, Amman, Jordan, who developed a first episode of venous thromboembolism, 32 patients were given warfarin for 24-months, while 32 patients stopped anticoagulation after completion of 6-months of therapy. Our goal was to determine the effects of extended anticoagulation on rates of recurrence of symptomatic venous thromboembolism and bleeding. The patients were followed for 12-months after stopping anticoagulation. RESULTS: After 24-months, 7 of the 32 patients (21%) who had standard anticoagulation for 6-months had a recurrent episode of thromboembolism compared to one of the 32 patients who received anticoagulation for 24 months (3%). Extended warfarin therapy for 24-months has resulted in an absolute risk reduction of 0.1% (p<0.05). This translates into 8 patients having to be treated for 24-months to avoid one recurrence without increasing the risk of major bleeding. Two patients in each group (6%) had major nonfatal bleeding, all 4 bleeding episodes occurring within the first 3-months of anticoagulation. After 36-months of follow up, the recurrence rate of extended warfarin therapy was only 3 patients (9%), which is a 43% relative reduction in recurrence of thromboembolism compared to standard therapy for 6-months. CONCLUSION: Patients with first episodes of idiopathic venous thromboembolism have an increased risk of recurrent venous thromboembolism and should be treated with oral anticoagulants for longer than 6-months, probably 24-months.
