 Welcome back to the revision series on dentistry and more. Today's confusing concepts and approaches are concept of health that is changing concept of health, changing concepts in public health, concepts in health care and approaches in health education. So these are very common question that is these two are very commonly asked repeatedly asked questions. These two you can include in your essays while writing essay on health education and health care delivery systems in India or primary health care or these two you can add up in your essay session. But these are commonly asked short essay or long essay or maybe even for short note. So these always get changed in your mind. So when question comes you might wrongly end up writing the wrong answer and losing all the marks. So let's see what is the concepts in health. So we have studied this in detail that is biomedical concept, ecological, psychosocial and holistic. This is basically about a person's health, a person, this is about public. So biomedical is nothing but absence of just disease like germ theory if the person is disease free is completely healthy. Ecological was pointing about the person's environmental balance if the balance is lost he will not be in a state of healthier condition and psychosocial is more of patients other factors like psychological and other factors are involving in psychosocial concept and holistic it's like everything comes under holistic including the spiritual aspect. So this is about a person's health how do we perceive a person's health and when we can say that a person is healthy and the various concepts. This is the earliest one and this is the latest one. By moving on to public health this is disease control phase this is started in 1880, 1882, 1920, this is 1920 to 1960 and this is 1960 to 1980 and 1982 to 2000. So disease control phase is almost like biomedical phase when we control the disease we can keep a group of people healthy so this is about public health so always when you're writing an answer think about the concept and where it will be perfectly matching. So disease control phase when we control the disease we can prevent health or prevent the diseases happening in a group of people. That was basically about sanitary reforms health promotional phase like 1920 to 1960 it was aiming to promote health by improving other factors not just the sanitary reforms like proper community health services and other health services. So during health promotional phase that basic health services concept where community health services concept where came into existence. Social engineering phase post world war phase where lots of lifestyle changes happened and the risk factors are emerging so controlling and this risk factors and its associated problems were addressing social engineering phase. Health for all phase it was a concept put forward by WHO because few people in the developed country and majority of the developing country were devoid of complete health care they were not getting actual or proper health care so to abolish that discrimination the WHO put forward this concept that is health for all phase health care is how the government provides health to the people so comprehensive health care is like womb to tomb concept put forward by Bose committee it was like everything we should provide to the people from womb to tomb concept but whereas basic health service it's like concept put forward by WHO and UNICEF so this comes under health care delivery system so basic health services it's like providing health care to the peripheral units and doctors the primary health care is the most accepted one primary contact point of people that is primary health centers and sub centers so these are the concepts coming under public health industry that is health public health and health care so this is a individual health public health and how government provides health care health education is how do we educate people about health that is administrative or service approach just like we provide everything at doorsteps they might not accept it because it will not be matching with the felt need of people legal or regulatory like by keeping punishment like epidemic act and asking people to wear helmets and putting fine for when they violate the traffic regulation it is by law we try to educate them it is by just providing whatever they want health education is the most appropriate one it is a slow process just like the movie ads we see before the movie regarding the tobacco cessation and primary health care concept is like a multi sectoral corporation involves all the sectors by educating a group of people so that is all about concepts and approaches so concept of health concept of public health concept of health care and approaches of health education so I will come up with another revision series in dentistry and more thank you
