A
The non-specific response of the body to any demand” & “That which produces stress”
4
Q
General adaptation syndrome (GAS):
A
- Alarm: Body recognizes a stressor and is in state of alarm (activation of flight or fight)
- Resistance: Follows alarm reaction, it is a removal or disappearance of symptoms

5
Q

Ethnic density effect
Refers to health benefits associated with living in a neighbourhood with a high concentration of others from one's own ethnic group
131
Myth buster 1 summary (IMG's are the solution to the doctor shortage in underserviced areas)
There is a greater demand for healthcare in rural and remote communities because they experience higher rates of chronic disease, traumatic accidents, and poor mental health than urban but there aren't enough health workers especially doctors. Therefore, many international medical graduates were recruited for temporary placement but many ended up leaving these communities after receiving their full license due to personal and social problems, so the problem for underserviced communities still remained in place without a solution. To fix this, the best hope is to encourage people who are already from rural areas to apply for medical school which would hopefully want to make them stay at the job
132
Myth buster 2 summary (User fees ensure better use of health services)
Article that debates whether user fees ensure quality of health services, while minimizing unnecessary hospital visits, and the answer was no, they do not. In fact they affect those who are chronically ill very negatively. It basically just obstructs access to needed care especially for those who cannot afford it and was not necessarily effective unless you had a higher income. And they ran up an experiment by the RAND Health Insurance, and found that user fees cause people to forego necessary treatment. So for example an elderly started taking less medicine and the conditioned worsened, so there was increase in patients ending up in hospitals
133
Primary health care services
Provides direct provision of first-contact health care services and coordinates patients' health care services. May include prevention and treatment of common diseases and injuries or referrals to other units
