April 7th has been designated as World Health Day by the World Heath Organization, and this year’s focus is on depression. In recognition of this day our posts will focus on depression and its treatment.
Researchers affiliated with the University of Vermont examined the relationship between magnesium intake and depression in adults. Using data from the National Health and Nutritional Survey (NHANES) researchers looked at subjects ages 20 and older, which included nearly 9,000 records. The NHANES is a population-based survey, which was designed to collect information on the nutrition and health habits of the U.S. population, using a random sampling method.
Magnesium intake was estimated from a 24-hour diet and supplement recall. The Patient Health Questionnaire was used as a tool to assess depression in adults.
What the researchers found was a bit unexpected- in those subjects younger than age 65 low magnesium was associated with greater depression, while in those subjects 65 and older low magnesium seemed to be protective of depression. The reason for this is not clear.
In addition, the researchers also found that over half of the adults in the survey do not consume adequate daily amounts of magnesium.
More research on this topic is needed, particularly to determine why the effect of magnesium on depression is somehow moderated by age. However, it is clear from this study that low magnesium intake in the 20-64 age population in the U.S. is associated with higher rates of depression.
