Public Health

  • Definition: Monitoring and regulating the health of a vast amount of people from a certain place e.g. in England we have the NHS for our public health organisation
  • Monitoring the health status of the community 
    • Epidemiology definition: The part of medicine that deals with distribution, commonness, and the possible control of disease as well as other components which contribute to a person’s health 
    • The NHS (National Health Service) often use statistics and epidemiology to monitor the health of the nation. This is so that they can see which areas they need to work on across the nation e.g. the current focus is on helping people change the way that they eat. To do this there is currently a campaign called “Change 4 Life” which helps you to make better decisions as to what you should eat 
    • By using research methods such as online surveys and doctors reports we are able to target which areas are in most need of help from healthcare services and helps us to understand the cause and effect of certain diseases
    • Also it can help us to pinpoint which communities are most at risk of certain diseases so we can put in extra intervention to help the health of the communities

Identifying the health needs of the population

  • Once we know where the problems lie then we will be able to target them in the best way possible to help to reduce the number of people that are diagnosed 
  • However, no everyone goes straight to the doctor when they become ill for a variety of reasons including the fact that they may think that the NHS won’t be able to help them 
  • As well as this those that are considered as vulnerable in life e.g. the homeless or those with a mental illness also may not go for help due to fear or not understanding the fact that they need professional help. As a result of this we may not be able to pinpoint exactly where help is needed most 
  • On the other hand, from the information that we are able to obtain we can target certain communities (e.g. the Asian community has a high percentage of people with type two diabetes) so that we are able to use the best course of action to reduce the number of people that are diagnosed

Promoting health

  • Definition: Allowing people to know that they are able to control their health and that they can make themselves healthier by putting in both social and environmental controls 
  • A way of doing this is to use national campaigns e.g. “Stoptober” where smokers are encouraged to stop smoking for 28 days
