Nationwide study suggests obesity as an independent risk factor for anxiety and depression in young people

Obesity is linked with an increased risk of developing anxiety and depression in children and adolescents, independent of traditional risk factors such as parental psychiatric illness and socioeconomic status, according to new research being presented at this year's European Congress on Obesity (ECO) in Glasgow, UK (28 April-1 May).

The nationwide study comparing over 12,000 Swedish who had undergone with more than 60,000 matched controls found that girls with were 43% more likely to develop anxiety or compared to their peers in the general population. Similarly, boys with obesity faced a 33% increased risk for anxiety and depression compared to their counterparts.

"We see a clear increased risk of anxiety and depressive disorders in children and adolescents with obesity compared with a population-based comparison group that cannot be explained by other known risk factors such as socioeconomic status and ", says Ms. Louise Lindberg from the Karolinska Institutet, Stockholm, Sweden who led the research. "These results suggest that children and adolescents with obesity also have an increased risk of anxiety and depression, something that healthcare professionals need to be vigilant about."

Anxiety and depression are reported to be more common in children with obesity than in children of normal weight, but it is unclear whether the association is independent of other known risk factors. Previous studies are hampered by methodological limitations including self-reported assessment of anxiety, depression, and weight.

To provide more evidence, researchers from the Karolinska Institutet in Sweden conducted a nationwide population-based study to investigate whether obesity is an independent risk factor for anxiety or depression. 12,507 children aged 6-17 years from the Swedish Childhood Obesity Treatment Register between 2005 and 2015 were compared to 60,063 controls from the general population matched for sex, year of birth, and living area.

The research team adjusted for a range of factors known to affect anxiety and depression including migration background, neuropsychiatric disorders, parental psychiatric illness, and . A total of 4,230 children and adolescents developed anxiety or depression over an average of 4.5 years.

Obesity was clearly linked with higher risk of anxiety and depression in childhood and adolescence. Girls (11.6% vs 6.0%) and boys (8.0% vs 4.1%) with obesity were more likely to be diagnosed with anxiety and depression than those in the over the study period.

In further analyses, excluding children with neuropsychiatric disorders or a family history of anxiety or depression, the risks were even higher. In particular, boys with obesity were twice as likely to experience anxiety or depression as their normal-weight peers—whilst girls with obesity were 1.5 times more likely.

"Given the rise of obesity and impaired mental health in young people, understanding the links between childhood obesity, depression and anxiety is vital", says Ms. Lindberg. "Further studies are needed to explain the mechanisms behind the association between obesity and anxiety/depression."

The authors acknowledge that this is an observational study and cannot prove that obesity causes depression or anxiety but only suggests the possibility of such an effect. They point to several limitations including that there is no weight and height data in the comparison group; unmeasured confounding may have influenced results; and that rates of and depression may be underestimated since a large proportion of individuals suffering from these conditions do not seek medical care.

Here are some interesting statistics

"Researchers found more than 2 billion people worldwide [30%] are now overweight or obese. The highest rates were in the Middle East and North Africa, where nearly 60 percent of men and 65 percent of women are heavy."

"Between 1980 and 2013, the prevalence of overweight or obese children and adolescents increased by nearly 50%. In 2013, more than 22% of girls and nearly 24% of boys living in developed countries were found to be overweight or obese."

-Will we ever know the cause? Couple this with declining fertility, sperm counts, general cognitive decline, and this

-indicates an unprecedented crisis in the collective health of the species. Is it environmental? Are other wild or domestic species experiencing such declines? Is it a toxin or contageon that only humans ingest or contract?

...does it have to do with the fundamental nature of the domesticated human animal itself?

Our brains are too big.

"the human brain demands more than twice as many calories as the chimpanzee brain, and at least three to five times more calories than the brains of [rodents]"

-They got that way from responding to the very unnatural demands of tribal living. Chronic overpopulation drove constant intertribal conflict. This selected for tribes with greater internal cohesion which enabled greater size and concerted animosity and aggression against other tribes.

The result was an unsustainable organ that does not remain functional for very long, if at all.

And without the crucible of constant intertribal conflict to weed out the severely dysfunctional before they have the chance to breed, the species begins to decline.

the science of improving a human population by controlled breeding to increase the occurrence of desirable heritable characteristics. Developed largely by Francis Galton as a method of improving the human race, it fell into disfavor only after the perversion of its doctrines by the Nazis."

-But did it really, or was it only vilified publically while being instituted globally? And has it in fact been with us for centuries?

The conquest of the western hemisphere was accompanied by a general and thorough depopulation using diseases spread by intent. New nations were established which invited immigrants but made it very difficult for them to get here. Only the best, brightest, or the most desperate and resourceful, could make the trip.

After ww2 the educational systems of western countries were expanded and retasked. Youth of sufficient intelligence were encouraged to leave their incipient cultures and comingle.
