Behavioral Trials in the Arab Gulf States: A Scoping Review

The leading chronic conditions in Arab Gulf States are modifiable by lifestyle change. Available evidence suggests a paucity of experimental studies on these conditions. We aimed to review the published randomized controlled trials on behavioral modification in the Arab Gulf States. Three databases (PubMed, Embase, and Cochrane) were searched for related keywords, and the records were screened for eligible studies; data were abstracted on trial characteristics (e.g. publication year, study population, primary outcome, intervention, control, follow-up, and outcome results), and a quality assessment of the trials was made. A total of 16 trials were eligible; 50% did not provide sample size calculation, and 31% did not designate a primary outcome. A majority of the trials did not explain randomization or allocation concealment (50%), did not blind outcome assessors (69%) or adopt an intention-to-treat analysis (56%); and 82% of trials found a significant intervention effect. More behavioral trials should be conducted overall and specifically for conditions for which there are no trials (e.g. respiratory tract infection and road injury).

Keywords: Arabs; Behavioral; Gulf; intervention; randomized controlled trials.
