The study explored how vitamin D knowledge, behavior, and attitudes are linked to BMI status in Saudi adults, involving 774 participants.
Obese participants excelled in identifying sunlight as a vitamin D source, while overweight participants were more likely to recognize food-related sources but misidentified some sources, like air.
Overall, while knowledge about vitamin D was high, significant misconceptions persisted, highlighting the need for targeted public health campaigns to improve awareness among high-risk groups.
