Epidemiology of obesity and control interventions in Saudi Arabia

Background: Prevalence estimates for overweight and obesity in the Gulf Cooperation Council countries, including Saudi Arabia, have increased over the last 4 decades. Although the World Health Organization encourages countries to implement initiatives aimed at controlling obesity, limited research has been published on the impact of such initiatives in Saudi Arabia. Aims: To assess the epidemiology of overweight and obesity in Saudi Arabia, describe and evaluate the effectiveness of past and current interventions, and recommend actions for prevention and control. Methods: A narrative review of data from the Global Health Observatory was used to determine yearly estimates of prevalence of overweight and obesity in Saudi Arabia from 1975 to 2016. Large-scale interventions aimed at controlling obesity and its risk factors in Saudi Arabia were identified and summarized. Results: Prevalence estimates of overweight and obesity among men and women in Saudi Arabia continued to increase from 1990 to 2019. Prevalence among adults was more than 60% and among children and adolescents it was 20–60%, suggesting a continuing trend. Interventions were identified but their impact on the prevention and control of obesity and its risk factors was unclear. Conclusion: Prevalence estimates of overweight and obesity have been steadily increasing in Saudi Arabia since 1975. Integrated, “whole-of-community” approach, with continuous evaluation, is needed to achieve sustainable prevention and control of obesity in the country.
