Importance of Unintentional injuries - ANSWER -More than 3 million people
annually die of unintentional injuries worldwide
-Cause of 7% of deaths worldwide
-Cause of 9% of total DALYs
Injury - ANSWER The result of an act that damages, harms, or hurts
-unintentional or intentional damage to the body resulting from acute
exposure to thermal, mechanical, electrical, or chemical energy or from the
absence of such essentials as heat or oxygen
Unintentional Injuries - ANSWER The subset of injuries for which there is no
evidence of predetermined intent
-suicide is not an unintentional injury
-does not include self-harm, interpersonal violence, collective violence, and
legal intervention
Examples of Unintentional Injuries - ANSWER -road injuries
-poisoning
-falls
-drownings
,-animal contact
-forces of nature
Why don't we call unintentional injuries accidents? - ANSWER it takes away
accountability
What is the largest causes of unintentional injuries? - ANSWER -road injuries
-poisonings
-falls
-fires
-drowings
Burden of Unintentional Injuries - ANSWER -DALYs from unintentional
injuries represent a larger share of total DALYs than deaths represent as a
share of total deaths
-Basically, the number of people who suffer disability annually is greater than
those who actually die
(Why is this important to public/global health?)
*Burden of Unintentional Injuries*
About _______% of deaths from unintentional injuries were in LMICs, mostly
from road injuries. - ANSWER 90%
*Burden of Unintentional Injuries*
About 4.2% of total deaths in high-income countries compared to 7.9% in
low- and middle-income countries.
,Why is there such a big difference? - ANSWER High-income countries have
lower rates of injury and have greater access to medically address them
*Burden of Unintentional Injuries*
Two thirds of deaths are among men. Why? - ANSWER Because men take
more risks, more risky jobs (selection bias)
Childhood Injury - ANSWER About 98% of childhood injury deaths are in low-
and middle-income countries
-Why? ----- Children are exposed to war and conflict, disease, and working
conditions
-What happens when this occurs in the US?
About 5% of total deaths for children come from children aged 0-4
23% of total deaths for children ages 5-14 in low- and middle-income
countries
For children aged 10-14, road traffic injuries are the 2nd leading cause of
death
Risk Factors for Unintentional Injuries - ANSWER *Developmental immaturity
relative to the dangers these children face in their environment*
*Poverty's influence on ability to provide adult supervision and child care*
-children are left on their own
*Exposure to unsafe workplaces with unsafe, hazardous, and
developmentally inappropriate machinery*
-60% of working children are exposed to unsafe conditions
, >40% of these children have suffered serious workplace injuries
*As children grow older, the incidence of injuries does not decrease*
-more developmentally mature young people tend to roam their
environments and encounter more risks and complex situations
Risk Factors for Falls - ANSWER -Young people: mostly associated with
physical activity and vary with socioeconomic status
-Older people: mostly related to age and overall physical condition
Risk Factors for Burns - ANSWER *Low income, poor housing, and living in
crowded areas*
-Rural dwellers suffer higher rates than urban people
-Children are more likely than any other age group
Risk Factors of Drownings - ANSWER -Young children are most likely to
drown
-Males are more likely to drown than females
-Children from poorer and larger families drown more frequently
Risk Factors for Poisonings - ANSWER -More likely in young boys under 5
than girls under 5 in LMICs
-Girls aged 5-14 are more likely to be poisoned than boys aged 5-14 in LMICs
-Low-income parents who are unable to supervise their children around
poisons are more likely to have their child poisoned than better off parents
Risk Factors for Road Traffic Injuries - ANSWER -Increasing rate of use of
motor vehicle in LMICs
