Vitamin D and depression
According to a new research from the Oregon University, it is seen that the low serum levels of vitamin D are associated with clinically significant symptoms of depression in otherwise healthy subjects.
The researchers conducted a series of evaluations, healthy women during a period of 1 month, and found that more than a third of the participants had depressive symptoms, almost half had insufficient vitamin D, and that the depressive symptoms have been provided by low levels of vitamin D.
Deficiency and insufficiency of vitamin D usually occur in young healthy women, and lower levels of vitamin D3 are linked to clinically significant depressive symptoms.
It is always noticed and said that depression is linked to the relationship with sunlight and then the concentrations of vitamin D have an important meaning for screening of depressive illness.
Noting that supplementation with vitamin D is at a low cost, is simple, and the action is low risk, the researchers add that given the health risks associated with the life span and the relative lack of vit. D, integration is justified.
The researchers examined 185 female college students who live in the northwest Pacific US, and studied by the Center for Epidemiologic Studies Depression (CES-D) scale at the basic level and then for each week for 4 weeks.
In addition, we measured the levels of serum vitamin D3 and C at baseline and at the end of the study period
Between 34% and 41% of participants reported clinically significant depressive symptoms, defined as a CES-D score of â‰Ą16, during the study period. An insufficiency of vitamin D3 (<30 ng / ml) was recorded in 42% and 46% of the participants at the beginning and end of the study, respectively.
After taking into account the season, the body mass index, race / ethnicity, diet, exercise, and time spent outdoors, the researchers found that lower levels of vitamin D3 in the whole study period were predictive of depressive symptoms to clinically significant (P <.05).
For a causal relationship to be established, we would need to be shown that supplementing with vitamin D is able to have a therapeutic effect on depression or quote.
So far, the results of studies that have looked at causality were mixed, but the important result is that an addition with supplements of vitamin D to the notes antidepressant therapies or initiated in periods not suspected of depressive illness, can always help each of we will.
