What is it about?

Using metabolic health as a representation of physical health and depressive symptoms to represent mental health, this study demonstrates metabolic health and depression affect each other such that when metabolic health worsens, individuals are more likely to develop depressive symptoms in the future, and individuals with depressive symptoms are more likely to have worse metabolic health in the future. Race and sex can affect this relationship, meaning this bidirectional relationship was stronger for females (compared to males) and White people (compared to Black people). Health behaviors such as smoking, exercise, and alcohol use did not affect the relationship between metabolic health and depression.

Why is it important?

This study demonstrated a strong relationship using a large sample (approximately 5000+ individuals) with data collected from each member of the sample for more than 30 years. This sample had approximately equal numbers of males and females/ Black people and White people which allowed for direct comparisons. This study has implications for the prevention and treatment of depression and metabolic disorders/ syndromes.
