Correlation Between Obesity and Mental Health Status in Riyadh, Saudi Arabia

Introduction: Recent studies show an increase in the incidence and prevalence of obesity worldwide. In Saudi Arabia, the prevalence of obesity, according to the latest studies, was estimated to be 24.7%. Rising rates of obesity are becoming a serious public health concern with well-documented physical and mental health consequences. Our study aims to measure the effect and the relationship between obesity and mental health status and to assess the impact on the quality of life in Riyadh, Saudi Arabia.

Methods: A cross-sectional observational study was conducted in Riyadh, Saudi Arabia. Data collection involved an electronic questionnaire encompassing patient demographics, their perspectives on obesity and its impact on mental health, as well as screening for common mental health disorders using GAD-2 and PHQ-9. Subsequently, the data were coded, entered, and analyzed utilizing both descriptive and inferential statistical methods, with the assistance of IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp.

Results: A total of 480 adult Saudi participants were included in the current study. Most of them were males (61.5%) in the age group of 18 to 40 years (77.3%). 13.1% of the participants had a first-degree family history of psychiatric illness, and 10.6% had a previous medical history of psychiatric illness. 86% of the participants think that obesity has a negative effect on the quality of life and mental health, and 98.1% believe that losing weight and treating obesity will play a role in improving the quality of life and mental health in general. Regarding the prevalence of mental health issues according to the PHQ-2 score, 151 (31.5%) of the participants were positive, out of whom 47 (31.1%) had mild depression, and 147 (30.5%) of the participants were positive using the GAD-2, out of whom 41 (27.9%) had mild anxiety, and the same percentage had moderate anxiety. There was a significant association between BMI and a previous history of psychiatric illness among females (P = 0.044).

Conclusion: Obesity and a higher BMI were found to be associated with a higher prevalence of depression and anxiety among the study participants. About one-third of the total participants had depression, and another one-third had an anxiety disorder.
