When you think of the country you often think of clean air, fresh food and physical activities to keep you healthy, but studies show that cities actually are even healthier than country living!

Our Fragile Intellect. Part II:

“In the previous piece I argued that we are slowly losing emotional and intellectual traits; but how did we get them in the first place? This is one of the most important questions of modern anthropology and the subject of much investigation and debate.”

The Evolution of ADHD:

“Attention-deficit hyperactivity disorder (ADHD) affects an estimated 8 percent of children (12 percent of boys) and 4.4 percent of adults in the U.S. ADHD has a large heritable component (around 70 percent), suggesting that genes play a role in its etiology and that it can be modified by natural selection.”

Schizophrenia An Urbanicity: A Major Environmental Influence – Conditional On Genetic Risk:

“More than 10 studies have consistently shown that around one-third of all schizophrenia incidence may be related to unknown but likely unconfounded environmental factors operating in the urban environment that have an impact on developing children and adolescents to increase, relatively specifically, the later expression of psychosis-like at-risk mental states and overt psychotic disorders.”

The Current Status Of Urban-Rural Differences In Psychiatric Disorders:

“A meta-analysis of urban-rural differences in prevalence was conducted on data taken from 20 population survey studies published since 1985. Pooled urban-rural odds ratios (OR) were calculated for the total prevalence of psychiatric disorders, and specifically for mood, anxiety and substance use disorders.”

City Living Helped Humans Evolve Immunity To Tuberculosis And Leprosy, New Research Suggests:

“New research has found that a genetic variant which reduces the chance of contracting diseases such as tuberculosis and leprosy is more prevalent in populations with long histories of urban living.”

City vs. Country: Who Is Healthier?

“For many urban dwellers, the country conjures up images of clean air, fresh food and physical activities. But these days, Americans residing in major cities live longer, healthier lives overall than their country cousins-a reversal from decades past.”
