Relationship of Dietary and Serum Zinc with Depression Score in Iranian Adolescent Girls.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

A validated Persian version of the Beck Depression Inventory (BDI) was used to determine the severity of depressive symptoms for all subjects.

Why It Was Studied

Zinc deficiency, which is common among Iranian populations, is believed to play a crucial role in the onset and progression of mood disorders such as depression in different stages of life.

The researchers have therefore investigated the relationship between serum/dietary zinc status and depression scores among adolescent girls living in northeastern Iran.

Who Took Part

PubMed indexes the participants as children and teenagers, women only.

How the Study Was Run

In design terms this was a randomized study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Serum zinc was measured by flame atomic absorption (Varian AA240FS) and the mean zinc intake was assessed using 3-day food record.

What Was Measured

The researchers have therefore investigated the relationship between serum/dietary zinc status and depression scores among adolescent girls living in northeastern Iran.
