Final answer:
Motor vehicle accidents are the leading cause of death for children ages 3-14, with head and traumatic brain injuries being major concerns. Proper restraints and safe driving can reduce this risk. Worldwide, children's health is also impacted by environmental factors like pollution, sanitation, and malnutrition.
Step-by-step explanation:
The leading crash causing death for children ages 3-14 is motor vehicle accidents. According to data, such accidents are major causes of immediate death and disability, particularly from head and traumatic brain injuries. While there have been shifts in accidental death causes over time, vehicle crashes remain a significant threat to the safety of children. To mitigate this risk, it is important for children to be properly restrained in vehicles, and for drivers to adhere to safety regulations and maintain attentive driving behaviors.
It's also important to address environmental factors that contribute to the health and safety issues for children worldwide, such as acute respiratory infections caused by indoor air pollution, diarrheal diseases from poor sanitation, and infectious diseases like malaria. These are exacerbated by malnutrition, which is linked to inadequate water and sanitation as well as poor hygienic practices.
