Study Notes

Definition of Health and Occupational Diseases

  • Health is defined as a state of complete physical, mental, and social well-being, and not merely the absence of disease or infirmity.

Characteristics of Work/Occupation

  • One essential characteristic of work/occupation is that it can have both positive and negative effects on health.

Primary Prevention of Occupational Diseases

  • The primary focus of primary prevention of occupational diseases is to prevent the occurrence of diseases.

Noise-Induced Hearing Loss

  • Hearing impairment resulting from exposure to loud sound is referred to as noise-induced hearing loss.
  • Noise-induced hearing loss is an important occupational health issue.
  • Factors that can contribute to noise-induced hearing loss include loud machinery, tools, and equipment.
  • One type of noise exposure that can lead to sudden hearing deterioration is impulse noise.
  • Approximately 40% of young people are estimated to be exposed to sufficient noise that could lead to hearing impairment.
  • The primary cause of occupational hearing loss is excessive noise exposure.

Prevention of Occupational Diseases

  • Secondary prevention of occupational diseases focuses on early detection and treatment of diseases.
  • Tertiary prevention of occupational diseases involves providing aids like hearing aids to workers suffering from sensory-neural hearing loss.
