There is however insufficient evidence to recommend that vitamin D be prescribed for people with cancer, although there is some evidence that hypovitaminosis D may be associated with a worse outcome for some cancers.

Hypovitaminosis D is a risk factor for depression; some studies have found that low levels of vitamin D are correlated with depressed feelings and are found in patients who have been diagnosed with depression.

In the medical literature, any of these may also be called by names on the pattern of " hypovitaminosis " or " avitaminosis " + " [ letter of vitamin ] ", for example, hypovitaminosis A, hypovitaminosis C, hypovitaminosis D.

17.
Xerophthalmia from " hypovitaminosis A " is specifically due to lack of the hormone-like vitamin A metabolite retinoic acid, since ( along with certain growth-stunting effects ) the condition can be reversed in vitamin A deficient rats by retinoic acid supplementation ( however the retinal damage continues ).

In the past, hypovitaminosis D has been defined by blood concentrations lower than 20 ng / mL . However, in more recent literature many researchers have considered 30 ng / mL to be an insufficient concentration of vitamin D . Subnormal levels of vitamin D are usually caused by poor nutrition or a lack of sun exposure.
19.
"' Vitamin D deficiency "', or "'Hypovitaminosis D "', can result from inadequate nutritional intake of vitamin D, inadequate sunlight exposure ( in particular sunlight with adequate ultraviolet B rays ), disorders limiting vitamin D absorption, and conditions impairing vitamin D conversion into active metabolites including certain bone mineralization, leading to bone softening diseases as rickets in children and osteomalacia and osteoporosis in adults.

Epidemiologic research to date has led to the identification of a number of risk factors for frailty, including : ( a ) chronic diseases, such as cardiovascular disease, diabetes, chronic kidney disease, depression, and cognitive impairment; ( b ) physiologic impairments, such as activation of inflammation and coagulation systems, anemia, atherosclerosis, autonomic dysfunction, hormonal abnormalities, obesity, hypovitaminosis D in men, and environment-related factors such as life space and neighborhood characteristics.
