Which population is at a higher risk for developing vitamin D deficiency?

Postmenopausal women are at a higher risk for developing vitamin D deficiency due to several physiological and lifestyle factors. After menopause, the decrease in estrogen levels can lead to an increase in bone resorption and a decrease in bone density, making calcium and vitamin D essential for maintaining bone health. The body's ability to produce vitamin D from sunlight also diminishes with age, and postmenopausal women may not get enough sun exposure or dietary intake to meet their vitamin D needs. Additionally, factors such as body composition and the tendency to stay indoors can further exacerbate the risk of deficiency in this demographic.

Other populations like teenagers, middle-aged men, and young adults can also experience vitamin D deficiency, but they are generally at a lower risk compared to postmenopausal women, who face unique hormonal and health-related challenges impacting their vitamin D status.
