Vitamin A deficiency is primarily known for its impact on growth and development, especially in children. One significant consequence of a lack of vitamin A is growth failure, as this vitamin plays a crucial role in cellular growth and differentiation. It is essential for various bodily functions, including the maintenance of healthy vision, immune function, and the integrity of skin and mucosal cells. Without adequate vitamin A, the body cannot properly support these functions, leading to stunted growth and developmental delays in children.

While the other options may relate to various nutritional deficiencies or health issues, they are not directly caused by a deficiency in vitamin A. For example, obesity usually stems from an imbalance in caloric intake and energy expenditure rather than a direct deficiency of a specific nutrient. Osteoporosis is more closely linked to deficiencies in calcium and vitamin D, affecting bone density and overall skeletal health. Anemia can result from iron deficiency, vitamin B12 deficiency, or other nutritional inadequacies, but it is not primarily associated with a lack of vitamin A. Thus, growth failure stands out as the specific problem linked to vitamin A deficiency.
