New research explores the link between obesity and depression

A new study in PLOS ONE examines the association between depression and obesity in middle to older-aged adults.

Previous research has indicated a relationship between obesity and depression, with one study showing nearly 60 per cent of people in one group had severe depression.

However, with other studies reporting conflicting results, this latest research aimed to examine body fat measurements and their association with mental health issues.

Key findings included that both body fat measurements, BMI and WHR, were significantly associated with depression.

The research found that both males and females with higher body fat were more likely to be depressed – even after lifestyle and specified diseases associated with obesity were considered. This association was stronger in females as compared to males; however, both were significant.

The study findings corroborate previous research indicating an increased risk of depression among people living with obesity. This link could be caused by reduced self-esteem, self-image, all of which can increase the risk of depression.

Researchers also highlighted the impact social factors may have on this association and how obesity may contribute to chronic pain.

However, it is unclear whether depression causes obesity or vice-versa, and further research is required to identify the reasons for the association.

The study was published in PLOS ONE.
