Transcript of Overpopulation and Its Relation to Mental Health

Urbanization and Its Relation to Mental Health
design by Dóri Sirály for Prezi
Urbanization = +Stress = -Mental Health
All these urban/crowding stresses have negative impacts on people's mental state.
greater tension, anxiety, stress depression, suicide, bipolar
increase aggression, hostility violence, homicide
social withdrawal social anxiety/phobia
learned helplessness clinical symptom for depression
drug and substance abuse substance abuse disorder, schizophrenia

Urbanization increases the risk of getting mental disabilities and behavioral problems.
What Can Be Done?
By the government...
planned urban growth
supportive health care
appropriate policies
employment rate
and a lot more...

By individual...
outdoor activities
rural/nature experiences
coping skills
develop hobbies & interests
actively seeking out for help - TALK TO SOMEBODY!
8000B.C. - 1A.D: the growth rate was under 0.05% per year.
A tremendous change occurred with the industrial revolution.
During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion.
Trends of the World Population
The map above shows urban areas with at least one million inhabitants in 2006.
Only 3% of the world's population lived in cities in 1800
This proportion had risen to 47% by 2000, and reached 50.5% by 2010. By 2050, the proportion may reach to 70%.
Trends of the Urban Population
Urbanization and Its Stress
Stress:
Socially,
social status/class, poor or violent neighborhoods, segregation, crime rate
Financially,
unemployment, low-income, high-cost for living in a city
Psychologically
general stress induced by crowdedness, busy schedule, competition, etc
Environmentally
noise, crowding, pollution, heat, etc
Urbanization: the relative increase of the urban population as a proportion of the total population.
Pros: better employment, education, health care,culture, and contribute significantly to national economies.
Peen et al. (2007)
higher rates for mood, anxiety, and substance use disorders in urban areas than rural areas.
the prevalence of psychiatric disorders gradually increased over five levels of urbanization.
urbanization was also positively correlated with prevalence with one or more disorders.

Peen (2009)
similar urban-rural correlations are also found all over the world such as Germany, Netherlands, France, Sweden, etc
Correlation Between Urbanization and Mental Health
Urbanization & Depression
Sundquist, Frank, and Sundquist (2004)
3-year follow-up study of the total Swedish population from 25 to 64 year-old with respect to first hospital admission for depression.
level of urbanization was defined by population density and divided into quintiles.
With increasing levels of urbanization the incidence rates of depression rose: the most densely populated areas (quintile 5) had 12–20% more risk of developing depression than the reference group (quintile 1).
Urbanization & PTSD
Mazza & Reynolds (1999)
examined the relationship of exposure to violence and PTSD symptoms in 94 young adolescents from an inner-city school.
participants completed Adolescent Psychopathology Scale—PTSD Subscale and the Exposure to Violence Questionnaire.
exposure to violence demonstrated a unique and positive relationship with PTSD symptomatology.
Urbanization & Schizophrenia
Peen (2009)
compared the admission rates for schizophrenia and 5 levels of urbanization.
the admission rate showed a much higher incidence of schizophrenia in the most urbanized areas of Netherlands.
Living In Urban & the Brain
Lederbogen et al. (2011)
examine how living in urban may affect neural social stress processing in humans.
healthy participants were given a social stress paradigm and their brain activities was recorded by fMRI.
urbanization level was categorized as city, town, and rural area.
with increasing urbanization, the stress-related brain area - amygdala and perigenual anterior cingulate cortex (pACC) (amygdala-regulated area) were also more activated.
