Obesity with Vitamin D deficiency tied to increased risk of depression
A study published in Clinical Laboratory has concluded that individuals at risk of depression have higher BMI and lower serum Vitamin D levels.
Previous research has associated vitamin D deficiency or hypovitaminosis with obesity and depression. A team of researchers investigated this further on,
“What is the association of vitamin D with depression in obese patients?”
The study included 107 obese patients who were followed up and treated at an obesity centre. There were two groups; one group was deficient in vitamin D with a serum 25(OH)D level of < 20 ng/mL, while the other not deficient group had a serum vitamin D level of ≥ 20 ng/mL.
According to BDI scores, patients were divided into two groups with BDI scores < 17 and ≥ 17.
The study results are summarised as follows:
- Those with a higher risk for depression with a BDI score ≥ 17 had higher weight and BMI. These patients had lower levels of serum 25(OH)D levels.
- There was a moderate positive association of BDI scores with BMI, a weakly negative relationship with vitamin D levels, weakly positive relationship with weight.
- The BDI score me-dians of 12 and 8 were higher in patients with serum 25(OH)D levels of < 20 ng/mL than ≥ 20 ng/mL.
- There was a higher risk of depression due to increased BMI and decreased serum vitamin D levels.
