1.                  Provision of knowledge about position of structure and functions of body organs.
2.                  Provision of awareness of position and roles of body organs
3.                  Enablement of acquisition of skills for maintenance of health hand washing, personal hygiene, brushing of teething etc.
4.                  health education sets acceptable standards of healthy behaviour
5.                  It encourages the inculcation of values and appreciation of values for things that promote health.

6.                  It facilitates prevention of infections.
7.                  It provides knowledge about body types and their potentials and limitations in relation to maintenance of health.
8.                  Health education provides knowledge of the role and importance of posture to health, facilitates the development of skills for dealing with emergency situations and sudden illness
9.                  It develops awareness of the consequences of undesirable behaviour.
The role of record keeping and research in the promotion and maintenance of health
            Health records refer to the documented information that pertains to health. It includes records of the health statistics showing birth and death rates. The records will also reveal the types of diseases that are sporadic, endemic or epidemic. It will also reveal the ages when people die, for example. Good statistics of this nature can show a government how many children die in infancy, a year, at school age, and the type of illness that causes great mortality at particular stages of life.
            Health records of treatment can inform drug distributors and manufactures which type of drug is used and the degree of its efficiency. Statistics of this nature collected from various clinics, hospitals etc are necessary to forecast what diseases a state or country could expect in the future if past records are reliable. The government uses these records to plan the medical and health services of the state.
            The role of record keeping in the promotion and maintenance of health cannot be over emphasized. This is because it is through these records that the effectiveness of health maintenance projects like the Expanded Programme on Immunization (EPI) and the extent of coverage is determined. This will help them to know the communities that need attention more than others thereby preventing the occurrence of certain childhood killer diseases.
            In a school set –up, health records such as hospital; records will help the school nurse to identify children who suffer from certain congenital or hereditary diseases such as sickle cell anaemia and heamophilia. This will help her to know the kind of attention to give these children in order to promote their health. it will also help the teacher to know children who have physical defects such as partial deafness or short sightedness and so on know how best to attend to them.
            The records on past epidemics will help the community or government involved to embark on some strategies to avoid future occurrences of such epidemics.
            Such records on the population distribution will help the government to know the type of health services to provide for the population. For example, where the population is dominated by infants, there will be more podiatrist hospitals or where old people dominate there will be more old people’s homes and rehabilitation centers.
The role of research in promotion and maintenance of health is very important. So many researches have been carried out over the years and have great impact on both community and personal health. Such researches include the following:
a.                  The nature of disease (pathology)
b.                  Organism that cause disease (microbiology)
c.                  The way in which disease – carry organism reach while population / groups (epidemiology)
d.                  Poisons and their sources (toxicology)
e.                  The chemical substances needed by the body maintain health (nutrition).
f.                   The function of hormones in maintaining health (endocrinology).
g.                  The ways in which heredity affects health (genetics) etc.
Through research, Johann Schole in (1939) showed that a mold-like plant was the cause of fervus, a fungal infection of the scalp. By knowing the cause of a disease, the curative and preventive measures become much easier to find.
Through research Louis Pasteur laid the foundation for the modern program of disease preventives. His studies showed that ‘diseases’ of beer and wine were produced by bacteria that led invaded the liquid and disturbed the usual alcoholic fermentation by producing undesirable fermentations of their own.
Basic methods of studying the bacteria are were developed by Robert Koch. He discovers how to kill and fix bacteria and strain them on a glass-slide for more effective study.
From such beginnings, the science of microbiology has developed with its many applications in industry, dairy, farming and food preservation as well as in public health and medicine.
The discovery of vaccination by Edward Jenner in 1796 has helped a great deal in the prevention of some deadly diseases like small pox. By introducing a mild form of small-pox into the body of a healthy person, he will have a mild attack and become immune t smallpox thereafter. Through vaccinations, so many diseases are being prevented today, thus helping to maintain health.
Through research the science of epidemiology was developed. The study of the cholera epidemic of the ‘Broad Street Wall’ by Dr. John Snow of London in 1854 may be regarded as the beginning of the science or epidemiology. Today, epidemiology gives information on the relationships of the various factors determining the frequency and distribution of diseases in a human community. This information will help the government and individuals to device means of protecting themselves against specific diseases, and the type of health facilities to provide in order to prevent a disease epidemic such as cholera. Epidemiology also provides information about the mode of transmission of specific diseases. This information will help individuals to form desirable health habits like closing their mouths while sneezing or coughing. This will help in health promotion.
Through research, new discoveries in genetics and in the development of new drugs to be used in the treatment of mental and emotional health are being made and mortality rates have declined greatly and more people are attaining higher levels of health.
