Obesity closely linked with mental health issues

Obesity closely linked with mental health issues

Developing countries like India are facing a dual health burden with obesity coexisting with malnutrition. A survey of 83,000 Indian women found that although 33 percent were malnourished, 12 percent were overweight or obese.

Increased consumption of high calorie processed foods and a shift towards completely sedentary lifestyles has resulted in an increasing rounder population across the world. We are in the grip of a global epidemic, and it has estimated that by the year 2020 obesity will be the single biggest killer on the planet. Obesity rates have risen at least threefold since 1980 in some areas of North America, the UK, Eastern Europe, the Middle East, the Pacific Islands, Australasia, and China.

Developing countries like India are facing a dual health burden with obesity coexisting with malnutrition. A survey of 83,000 Indian women found that although 33 percent were malnourished, 12 percent were overweight or obese. Of particular concern is the increasing rate of child obesity, especially in the Asian diaspora. Urbanisation in China has lead to harvesting an unhealthy lifestyle, as the Chinese government calculates that 1 in 10 city-dwelling children suffer from obesity. In Japan, obesity among nine-year-old children has tripled. While we do not have any consolidated figures for India, doctors say they are witnessing a clear trend towards an increase in obesity among children. Research has shown that while there is no clear, one-way connection between obesity and depression, a vicious symbiotic cycle is eminent to the extent that they feed off on the mental stability of the afflicted individuals. In fact, there is a bi-directional association between mental health issues and obesity, with an entrenched impact on the risk factors associated with obesity and mental health. Along with that, there are implications of psychological distress caused by weight-related stigma and discrimination, evidence suggests that people with mental health issues are more prone to obesity.

"Compared to adults with normal weight, adults with a Body Mass Index (BMI) greater than 30 are more likely to be diagnosed with Coronary Heart Disease (CHD), hypertension, stroke, high cholesterol, gout, osteoarthritis, sleep problems, asthma, skin conditions and some types of cancer. Obesity also is an important causal factor in type two diabetes, and it complicates the management of the disease, making treatment less effective. Obesity may also trigger a series of psychological disorders including depression, eating disorders, distorted body image, and low self-esteem. Binge eating may explain, at least in part, the relationship observed between obesity and depression. This may be because binge eating could contribute to weight gain and obesity, which, in turn, may negatively affect mood. Furthermore, recurrent episodes of binge eating are extremely unpleasant for those who experience them and may put the individual at higher risk of clinical depression," said Dr. Prakriti Poddar, Expert in Mental Health, Director Poddar Wellness Ltd, Managing Trustee of Poddar Foundation.

The relationship between obesity and mental health issues is a complex one and there exist different theories about the association between the two. Some researchers suggest that obesity can lead to mental health problems, whilst others have found that people with such problems are more prone to obesity. Other studies have found no association between the two.

Results from the most recent systematic review of longitudinal studies point towards bidirectional associations between depression and obesity. Another recent systematic review and meta-analysis found a weak but positive association between obesity and anxiety disorders. Obesity is also associated with an increased risk for a variety of chronic diseases, most of which are associated with depression that in turn can precipitate chronic disease due to diminished treatment adherence and or response.

Obesity ushers in a series of medical issues amongst the afflicted, with detrimental implications on the overall well-being. Increased medical problems and mobility restrictions associated with obesity have a direct impact on psychological well-being, leading to depression, eating disorders, a distorted body image, and low self-esteem. There is less research on the mechanisms that may cause adults with mental health disorders to become obese. It has been suggested that poor mental health can lead to unhealthy lifestyle choices and increased appetite," added said Prakriti Poddar.

A combination of the biological effect of increased stress alongside poor adherence to weight loss programmers, binge eating, negative thoughts, and reduced social support, may make it difficult for a depressed person to avoid weight gain. There is also evidence that people with chronic or repeated episodes of depression are at particular risk of subsequent obesity.

There is an urgent need for evaluations of weight management interventions, in terms of both, weight loss and psychological benefits to help physicians and psychologists better deal with obesity-related mental health problems. We need to develop a better understanding of the two-way link between mental disorders and obesity to develop improved curative practices to address this increasing burden.
