    Study Notes

    Health Statistics and Epidemiology

    • Demography is the study of population size, composition, and distribution.
    • Population refers to the number of people in a specific area or time period.
    • Household is a group of related or unrelated people living together in the same dwelling unit.
    • Census is an official count of the population.
      • De jure assigns people to their usual place of residence.
      • De facto assigns people to the place they are at the time of the census.
    • Sample surveys are used to gather information about a population.
    • Comparison by Census is a method used to assess population changes.
    • Birth Rate (CBR) is the average number of live births per 1,000 people in a population per year.
    • Death Rate (CDR) is the average number of deaths per 1,000 people in a population per year.
    • Natural Increase (NI) is the difference between births and deaths in a population over a specific time period.

    Demographic Indicators

    • Population Distribution: Illustrates the proportion of people living in urban or rural areas.
    • Sex Ratio: Represents the number of females per 1,000 males in a population.
      • For example, 967 females per 1000 males in Philippines 2018.
    • Age Composition: Describes the proportion of the population in different age groups. The median age is the age in the middle of the ordered population.
      • For example 18 years old in a specific population dataset.

    Vital Health Statistics

    • Crude Birth Rate (CBR) Example: (Births/population) x 1000 = CBR
    • Crude Death Rate (CDR) Example: (Deaths/population) x 1000 = CDR
    • Rate of Natural Increase (NRI) = CBR - CDR
    • Maternal Mortality Rate (MMR) : Deaths due to pregnancy, childbirth and puerperium / Total live births x 1000
    • Fetal Death Rate (FDR) is the death of a fetus before its expulsion from the mother.
    • Neonatal Death Rate (NDR) measures the risk of death in the first 28 days of life per 1000 live births
    • Attack Rate (AR) is the proportion of people who contract a disease within a specific time period.
    • Case Fatality Rate (CFR) is the proportion of cases resulting in death in a specific time period.

    Incidence and Prevalence

    • Incidence Rate (IR) The number of new cases in a defined population over a given time period, often expressed per 1000 people.
    • Prevalence Rate (PR) The total number of cases (existing and new) in a defined population at a specific time, often expressed per 1000 people.

    Epidemiological Investigation

    • Epidemic: The occurrence of more cases of a disease than expected in a given area or group of people over a period.
    • Outbreak: Localized increase in the incidence of disease in a specific area.
    • Sporadic: Occurs infrequently and irregularly.
    • Endemic: Constant or usual prevalence of a disease.
    • Clustering: Aggregation of cases in a particular area.

    Infectious Disease

    • Agent: The microorganism causing the disease.
      • Bacteria: Examples: Tuberculosis, Salmonellosis, Streptococcal infections
      • Viruses: Examples: Viral hepatitis, influenza
      • Protozoa: Examples: Malaria, amoebiasis
    • Host: The person who can get the disease.
    • Environment: Extrinsic factors affecting the interaction of agent and host
      • Examples include: geology, climate, insects, crowding, and sanitation.

    Surveillance System

    • Philippine Integrated Disease Surveillance and Response System (PIDSR)
    • Event-based Surveillance Response (ESR)
    • Field Health Service Information System (FHSIS)
    • National HIV/STI Surveillance and Strategic Information Unit (NHSSS)
    • Online National Injury Electronic Surveillance System (ONEISS)
    • Philippine Statistics (PHS)
