Abstract Rapid economic growth, improved living standards, and immense urbanization in the Kingdom of Saudi Arabia (KSA) have affected nutritional habits and physical activity. Recent increases in physical inactivity, sedentary behaviours, consumption of caloric-dense diets, and sugar-sweetened beverages have led to overweight and obesity and non-communicable diseases (NCDs). This study's objectives are to 1) determine current prevalence of and risk factors for obesity, and 2) predict the probability of obesity among full-time employees of Sadara, the largest chemical company in KSA. In 2019, a written survey in both Arabic and English was administered to 505 Sadara employees randomly selected from five Sadara locations. A number of factors possibly associated with BMI were examined using Chi-Square test: age, physical activity, screen watching, childhood region, nationality, fat intake, sugar intake, family size, household income, and consumption of meal-replacement bars. Logistic regression was performed to compare the trends and predict conditional probabilities of obesity. The sample was 92% male, 61% Saudi, from the Eastern Province of KSA, with a mean age of 34 years. Employees aged 30–39 years were found to have 1.8 times greater odds for obesity than the youngest employees (below 30 years). More specifically, those aged 30–39, who grew up in the Eastern Province, who had low physical activity and long periods of watching electronic screens had the highest probability of obesity (more than 66%). Workplace wellness programs that focus on lifestyle habits could help reduce the high prevalence of overweight and obesity and associated NCDs in KSA.
