Health Program Indicators Quiz

Indicators of Health Programs

• Types of Indicators:
  • Input: Measures resources used (e.g., number of posters, trained volunteers).
  • Output: Immediate results from activities (e.g., couples reached, classes conducted).
  • Outcome: Short-term changes (e.g., increased knowledge, family planning acceptance).
  • Impact: Long-term community changes (e.g., reduction in family size, lower growth rates).

Health Status Indicators

• Categories include measures of morbidity, mortality, and fertility.

Computing Indicators

• Absolute Numbers: Simple counts that are easy to understand but may lack context for comparisons.

  • Example of measles cases in Provinces A and B demonstrates absolute counts versus percentage of infected children.

• Ratios: One number divided by another, used for metrics like sex ratio where the numerator is distinct from the denominator.

• Proportions: A specific type of ratio where the numerator is part of the denominator, often expressed as a percentage.

• Rates: Measure frequency of events over time or space, crucial in health metrics like disease incidence.

Demography

• Examines human populations by size, structure, and distribution.
• Key factors affecting population size:
  • Natality (birth rate)
  • Mortality (death rate)
  • Migration (immigration & emigration).

Methods of Population Allocation

• De Facto Method: Counts individuals where they are physically present during census.
• De Jure Method: Counts according to usual residence.

Population Composition

• Describes demographic variables, primarily through age and sex.
• Influenced by birth rates, death rates, emigration, and immigration.

Age Composition

• Median Age: Age that divides the population into two equal halves.
• Age Dependency Ratio: Measures economic support potential, comparing dependents (children and elderly) to the working-age population.

Sex Composition

• Sex Ratio: Number of males per 100 females, providing insight into gender distribution.

Population Pyramid

• Graph depicts age and sex structure, with males on the left and females on the right, showing demographic trends.

Population Distribution

• Reflects geographic spread and is influenced by physical, political, social, and economic factors.
• Key indicators: population density and crowding index.

Population Estimation

• Forecasts future population based on trends in fertility, mortality, and migration.
• Important for analyzing trends, resource allocation, and planning.

Measures of Change in Population Size

• Natural Increase: Calculated as the difference between births and deaths.
• Rate of Natural Increase: Crude birth rate minus crude death rate.
• Relative Increase: Percentage change based on census counts.
• Absolute Increase: Average number added yearly.

Estimation Techniques

• Component Method: Accounts for births, deaths, immigration, and out-migration.
• Mathematical Methods: Include arithmetic, geometric, and exponential approaches for predicting population changes.

Rate of Change and Future Estimates

• Exponential Growth: Uses the formula r = In(Pt / P0) / t to estimate change rates.
• Future Population Estimation: Formula Pt = P0 * e^(rt) calculates population growth based on previous counts and growth rates.

Practical Example

• A dataset of Philippine census information from 1995 to 2000 can be used to estimate metrics such as the rate of change, future populations, and time projections for reaching specific population milestones.
