Exploring Sedentary and Nutritional Behaviour Patterns in Relation to Overweight and Obesity Among Youth from Different Demographic Backgrounds in Saudi Arabia

Background: The prevalence of overweight and obesity has increased over the last three decades, becoming a major public health concern. This issue is particularly pressing in terms of the impact it has on the population of the Kingdom of Saudi Arabia (KSA). Thus, the aim of this research was to explore the nutritional and lifestyle habits of youth in the Al-Ahsa region of the KSA. Methods: This cross-sectional study included a total of 1270 secondary-school boys and girls (15–19 years) from all five of the Al-Ahsa Governorate districts. BMI and waist circumference measurements were recorded using anthropometric measurements, and the lifestyle–Arab Teens Lifestyle Survey (ATLS) was used to measure sedentary and eating habits. Results: Chi-square analysis revealed that a higher proportion of females (90.68%) than males (79.18%) exceeded two hours of daily sedentary time. Frequent sugary drink consumption (>3 times per week) was similar in males (67.40%) and females (66.11%). Students from different geographical locations showed significant differences in exceeding cut-off scores for fast food (χ 2 = 24.503, p < 0.001), cakes/doughnuts (χ 2 = 8.414, p = 0.015), sweets/candy (χ 2 = 19.613, p < 0.001), and energy drinks (χ 2 = 21.650, p < 0.001). Conclusions: Al-Ahsa is the largest governorate in the KSA. It has some of the largest health risks regarding obesity and poor lifestyle habits. This study highlights the major need for future research and policy interventions.
