Title: ETHICS AND PUBLIC HEALTH POLICY


1
  • ETHICS AND PUBLIC HEALTH POLICY

The Universal Salt Iodisation in India
A Case Study
2
Universal Salt Iodisation in India
  • Ethics and Public Health Policy
  • Iodine and consequences of deficiency
  • Extent of the problem
  • Why universal salt iodisation
  • Issues
  • Is IDD a public health problem!
  • USI and small salt producers
  • USI and cost of salt
  • Mandatory Vs Voluntary

3
  • Ethics
  • Distinction between right and wrong
  • Moral values
  • Rights, duties and obligations

Societal norm acceptable and unacceptable conduct
4
Ethics, Morality, Values, and Law
  • Ethics and Morality
  • The moral values of society are the basis of many
    of our laws
  • Community standards are also influenced by social
    values
  • Health-related social values - remarkable change

5
Principles of Biomedical Ethics
  • Respect for autonomy
  • Human dignity and freedom
  • Nonmaleficence
  • primum non nocere first do no harm
  • Beneficence
  • Principle of doing good
  • Justice
  • Fairness, equity and impartiality

6
  • Quarantine
  • Resource allocation
  • New situations
  • Advances in medical science - Organ transplant
  • Life support
    systems
  • Changing social values - ethics related to female
  • reproductive
    behaviour

Principles of Biomedical Ethics

Iodine
  • Iodine is a trace element
  • Is an essential micronutrient
  • All vertebrates extract iodine, concentrate it
    and secrete it in hormonal form
  • Thyroid hormones are iodinated molecules of
    tyrosine
  • Iodine is an essential component of the thyroid
    hormones
  • This is the only confirmed role for iodine
  • It is present in the body in minute amounts
    15-20 mg i.e., 0.02 x 10-3 of body wt
  • The daily requirement is 150 µg

8
Iodine Deficiency
  • Iodine is sparsely distributed over the surface
    of earth
  • Iodine is a water soluble element
  • Over millions of years, it has been leached from
    the upper crest of earth
  • Glaciations, heavy rain on sloppy ground,
    repeated flooding

11
Endemic Goitre
  • Goitre
  • Any enlargement of the thyroid gland
  • Endemic goitre
  • is defined as the presence of generalized or
    localized thyroid enlargement in 5 percent or
    more of the school age children (age range 6-12
    years).

12
Population effect of iodine deficiency
13
What is the social cost of Iodine deficiency
  • Are children from an iodine-deficient area who
    are not manifestly cretins still at risk of
    having impaired mental and motor development?
  • Is the so called normal iodine-deficient
    population undamaged and really normal?

14
Iodine and its relationship to cognitive
development
  • Intellectual assessment of school children from
    severely iodine deficient villages
  • Mehta M, Pandav CS, Kochupillai N. Indian
    Pediatr 198724467.
  • Developmental lag in pre-school children of
    goitrous mothers.
  • Upadyaya SK et al. Indian Pediatr 198320259
  • Intellectual and motor development in school
    children from severely iodine deficient region -
    Sikkim

Database on IDD, 1993-2003.
17
Is IDD a Public Health Problem in India?
18
Iodine Deficiency Disorders in India
  • High prevalence of goitre and cretinism in the
    Himalayan, sub-Himalayan terai.
  • ICMR study 1986a
  • 14 districts from 9 states
  • n4,09,923
  • Goitre prevalence 21.1
  • Cretinism prevalence 0.7
  • DGHS Surveys
  • 275 districts surveyed
  • 235 are endemic. These districts cover all states
    and Uts
  • ICMR Task Force Study 1989
  • WHO SEARO SEA/NUT/138,1997pp1-

Why Iodise Salt?
  • Salt is consumed by all
  • Intake is more or less constant
  • Technology used to iodise salt is simple
  • Iodisation is inexpensive
  • Does not change the colour or taste

IODIZATION
Phoda salt

Crystal salt
1.50 2.00 Rs./Kg
Powdered salt
2.00 4.00 Rs./Kg
Refined salt
gt 4.00 Rs./Kg
27
Cost of Salt Iodization Crystal iodised salt in
loose
28
Cost of Iodised Salt
  • Cost of iodisation is a small fraction of the
    sale price of iodised salt
  • Packaging, transportation and trade margins are
    the main causes of cost increase

Why Should Government Take Lead?
  • Health Mandate Responsibility to protect
    population health. Individuals often cannot make
    good choices when the benefit is preventive or in
    the future. Health is a Merit Good.
  • Market Maker USI has Positive externalities when
    benefits accrue not only to consumers, but to
    society as a whole, then governments role is to
    encourage greater production
