How do factors that affect human health differ in developed versus developing nations?

Why You Should Care

Death rates vary between developing and developed countries because those populations face different hazards. Death rates due to environmental diseases are much higher in developing countries while death rates in developed countries are more likely due to “lifestyle” choices like diet and amount of exercise.

Developing countries face greater risks from environmental diseases primarily due to a lack of resources to prevent the modifiable environmental hazards. Programs like the GWD and malarial initiatives in Africa are often limited by lack of governmental funds.

Developed countries face greater risk from lifestyle diseases such as diabetes, heart disease, and lung cancer. Environmental diseases are less common because they have resources to spend educating and modifying the hazards of environmental diseases. However, some environmental diseases, such as malaria, West Nile virus, and Lyme disease, are spreading as climate change modifies the environment expand their range northward.

Several factors work together to shorten average life span of low-income citizens. Poorer countries have less budget to provide health care access and resources to its citizens, and so they are less likely to survive diseases that are preventable in richer countries. Also, poorer countries have lower standards of living, so food and medicines are more expensive. Children are more likely to suffer and die if they are not given access to a good diet and vaccinated against common diseases—both of these are easier to access in richer countries and so mortality among children is much lower. Those children live to become adults and are less likely to die from the same disease, which increases the average life span considerably.
