Lifestyle Behaviors and Socio-Demographic Factors Associated with Overweight or Obesity Among Saudi Females Attending Fitness Centers

To examine the associations of overweight or obesity with several lifestyle and socio-demographic factors among Saudi women attending fitness centers in Riyadh. Saudi females (n = 460) aged 16 years and older were recruited from 12 randomly selected fitness centers in Riyadh, using a stratified clustered sampling technique. Bodyweight and height were measured. Lifestyle behaviors were assessed using a previously validated instrument, and included physical activity, sedentary behaviors, sleep, and dietary habits. Over 62% of the participants were either overweight or obese. Mean BMI values for females younger than age 30 years (26.4 ± 5.3) were significantly lower than those 30 years of age or older (29.2±5.6, >0.001). There was a significant correlation ( = 0.450, < 0.001) between BMI levels and the participant's reason to engage in exercise for weight loss. Females who were overweight/obese are significantly older, married, have more children, have a lower educational degree, earn less income, have higher numbers of obese in the family, and had attempted to lose weight more frequently than non-overweight/non-obese females. No significant differences were detected between females who were overweight/obese and those who were not overweight/obese in the majority of the lifestyle-related variables, except that females who were not overweight or obese showed lower weekly consumption of milk and dairy products ( =0.029) and higher intakes of fast foods per week ( =0.049). Weight loss attempts, age, number of obese in the family, and females' education level emerged as the most important contributory factors to obesity status, explaining nearly 23% of the common variances. A better understanding of the relationships between obesity and lifestyle behaviors is necessary for effective prevention and management of obesity in Saudi females.
