Health : Health is state of complete physical and mental well being not merely an absence of disease or infirmity.
Sullivan’s index: This index (expectation of life free of disability) is computed by subtracting from the life expectancy the probable duration of bed disability and inability to perform major activities.

Determinants of health

  • Heredity
  • Environment
  • Life-style
  • Socioeconomic
  • Health and family welfare
  • Other factors like health related systems ( eg: food and agriculture, education, industry, social welfare, rural development )

Indicators of health

Characteristics

  1. Valid
  2. Reliable
  3. Sensitive
  4. Specific

Indicators may be classified as

1.  Mortality indicators

  1. Crude death rate: The  number of deaths per 1000 population per year in given community
  2. Expectation of life: Life expectancy at birth is “the average number of years that will be lived by those born alive into a population if the current-age specific mortality persists.
  3. Infant mortality rate: Ratio of deaths under 1 year of age in a given year to the total number of live births in the same year.
  4. Child mortality rate: Number of deaths at ages 1-4 years in a given year per 1000 children in that age group at the mid point of the year concerned.
  5. Under-5 proportionate mortality rate: Proportion of total deaths occurring in the under 5 age group.
  6. Maternal (puerperal) mortality rate:
  7. Disease specific mortality
  8. Proportional mortality rateMorbidity indicators

They are

  1. Incidence and prevalence
  2. Notification rates
  3. Attendance rates at out patient departments, health centres, etc
  4. Admission readmission and discharge rates
  5. Duration of stay in hospital
  6. Spells of sickness of absence from work or school

2. Disability rates

a) Event type indicators

(i)  Number of days of restricted activity

(ii) Bed disability days

(iii)  Work loss days (or school loss days) with in a special period

b)  Person type indicators

(i)  Limitation of mobility

(ii) Limitation of activity

3. Nutritional status indicators

  1. Anthropometric measurements of pre school children
  2. Heights (and some weights) of school children at school entry
  3. Prevalence of low birth weight (less than 2.5 kg)

4. Health care delivery indicators

  • Doctor population ratio
  • Doctor-nurse ratio
  • Population-bed ratio
  • Population per health/subcentre
  • Population per traditional birth attendant

5. Utilization rates

6. Indicators of social mental health

7. Environmental indicators

8. Socio-economic indicators

9.  Health policy indicators

10. Indicators of quality of life

11. Other indicators
