Higher BMI can affect mental health, according to a recent study focused on identifying the impact of physical health, like body weight, blood pressure and heart health, to see whether people with poorer physical health proceeded to be less cheerful and less happy with their lives.
The researchers used a technique called Mendelian randomization for the study published in the Journal of The BMJ. The team asked whether poorer physical health causes lower mental well-being, or whether people with lower mental well-being will more probably have later issues with their physical health.
This technique helped them comprehend the sequence with the help of genetic variants that have been linked with physical health and mental well-being. Not at all like past methods, this technique precludes the impact of different components that may cause both physical health and mental well-being.
Team tested 11 measures of physical health including coronary artery disease, heart attack, blood pressure, cholesterol, body fat and Body Mass Index (BMI). Higher BMI on lower mental well-being were found to have a steady causal impact. There was little confirmation that other physical health traits were prompting less happiness and life satisfaction.
the senior author of the study, Dr Claire Haworth said in a statement that, “Results so far highlight the pressing need to tackle the obesity crisis because higher BMI is causing the population to be less happy and less satisfied with their lives. This information could be immediately useful to clinicians encouraging patients to maintain a healthy weight.”
