  2. Outline of Presentation • Iterative Loop: Research – Policy - Programme • World In Which Policies Were Being Made • World In Which Policies Should Be Made – A Case Study of NIDDCP • Lessons Learnt From the NIDDCP • In Summary…

  3. ITERATIVE LOOP Research, Policy, Programme POLICY RESEARCH PROGRAMME

  4. Clinical Policy and Public Policy Relationship between Clinical Epidemiology & Public Policy Basic (Bench) Research – Uncovers Promising Intervention Clinical Epidemiology – Assesses Efficacy & Effectiveness Economic Evaluation – Assesses Efficiency Health Policy – Assesses Implementation Clinical Policy E.g. Deep vein thrombosis On an inpatient Vs. outpatient basis Public Policy Evaluation of the use of research findings & determinants of that use

  5. The World In Which Policies Were Being Made 1) Health Problem/Issue 2) Information 3) Institutional structure for decision making 4) POLICIES

  6. World In Which Policies Should Be Made 1) Health Problem/Issue 2) Information 3) Values 4) Institutional structure for decision making 5) POLICIES

  11. From Information to Knowledge

  12. World In Which Policies Were Being Made Information Evidence - Large no. of studies Data - Disaggregated and aggregated data Research - Evidence based Community & Lab studies KNOWLEDGE Researchers & Universities –Epidemiologists, Public Health Specialists, Scientists & Nutritionists Advocates - Scientists Media - Print & Electronic

  13. Legacy of The Legend Science & Society Prof. V. Ramalingaswami [8 August 1921 – 28 May 2001

  14. Prof. Madhu G Karmarkar, Former Prof. & Head, Department of Laboratory Medicine, AIIMS, who has been intimately associated with Prof. Ramalingaswami’s Kangra Valley Study and events thereafter to take us through the study

  15. Genesis of National Programme - 1 The Kangra Valley Project (1956-1972) • Study design : Community based prospective controlled trial • Study area : Kangra Valley , Himachal Pradesh Divided into 3 zones –A , B , C • Study period : 1956 - 1972 • Study Duration : 16 years • Study population : 1,00,000

  16. Kangra

  17. Kangra Valley Study Area Dharamsala From Pathankot Zone – B PLAIN SALT To Kulu Zone – C KIO3 SALT Zone – A KI SALT

  18. Genesis of National Programme - 2 The Kangra Valley Project (1956-1972) • Study Population : School Age Children (SAC) • Intervention : TECHNICAL • Baseline survey in 1956. • Salt* distributed to the 3 zones Zone A – Potassium iodide Zone B – Unfortified salt Zone C – Potassium iodate 3. 15 gms of salt/person/day 4. So as to ensure 200 mg of Iodine *Salt Produced at Sambhar Lake with UNICEF Assistance

  19. Genesis of National Programme - 3 The Kangra Valley Project (1956-1972) • Intervention : ADMINISTRATIVE • Price parity • Legislation • Govt. shops • Outcome variable: Goitre prevalence among school age children

  20. Genesis of National Programme – 4 INTERVENTION

  21. Genesis of National Programme – 5 INTERVENTION

  22. Genesis of National Programme – 6 INTERVENTION

  23. The Kangra Valley Project (1956-1972) Conclusions Iodine supplementation in the form of adequately iodised salt on a regular and continuous basis reduces goitre prevalence Recommendations • Establish a National Goitre Control Programme

  24. Scenario after Kangra Valley Project Second Five Year Plan (1962) National Goitre Control Programme (NGCP) launched Aims : 1) Initial survey to identify endemic areas 2) Production & Supply of iodised salt to endemic areas 3) Impact assessment surveys after five years Approach : Endemic district specific salt iodisation

  25. Dr. Chandrakant S Pandav, Member, Clinical Epidemiology Unit, & Addl. Prof., Centre for Community Medicine AIIMS, who has been intimately associated with Prof. Ramalingaswami’s work since 1978 to take us through the events thereafter

  26. NGCP Activities (1962-1983) Total No. of Salt iodisation plants : 12 (UNICEF assistance) Location: Rajasthan : 5 Gujarat : 3 West Bengal : 4 Estimated need/year : 1.00 million tons (100%) Production Capacity / year : 0.38 million tons ( 38%) Actual production / year : 0.15 million tons ( 15%) Goitre = No pain = Not a cause of mortality = = Cosmetic Problem = Low priority program

  27. The World In Which Policies Were Being Made 1) Health Problem/Issue 2) Information 3) Institutional structure for decision making 4) POLICIES

  28. New scientific evidence : 1962 – 1983 • Neonatal Hypothyroidism program – A pilot study Use of the primary health care setup to determine the incidence of neonatal hypothyroidism & Initiate treatment • Gradual shift of focus from endemic goitre to iodine & brain development Studies on iodine deficiency & IQ (13.5 points) & learning skills in school children from iodine deficient & sufficient areas

  29. New epidemiological evidence: 1962-1983 • Delhi study : Endemic Goitre in Delhi, 1980 • Extra Himalayan foci of IDD reported • 1984 – 86 : ICMR multicentric study 14 districts in 9 states Goitre Prevalence : 21.1% Endemic cretinism: 0.7% No state or union territory is free from Iodine Deficiency Disorders as a public health problem

  30. World In Which Policies Should Be Made Institutional Structure For Decision Making Efforts Since 1980s FORMAL STRUCTURE Executive - Law making decisions Legislature - Political support Bureaucracy - Policy decisions INFORMAL STRUCTURE Networks - NGOs, Health care providers, public health experts Coalition - Partnership of educationists & communication experts Stakeholders - Salt industry, salt regulators Citizens - Consumers

  31. The Turning Point of The Programme:1983 Meeting With The Prime Minister of India: Mrs. Indira Gandhi Questions asked by Mrs. Indira Gandhi: • What is Iodine Deficiency? • Why should I be Interested in National Goitre Control Programme (NGCP)? • How is it going to contribute towards Prime Minister’s 20 Point Programme?

  32. Iodine Deficiency – A Disease of The Soil Effect on people : HUMANS Health & Socioeconomic impact Effect on animals : LIVESTOCK Clinical & Reproductive disorders, decreased productivity Low Availability of iodine : PLANTS Iodine poor feeds & fodders, goitrogens SOIL EROSION WATER, SOIL Environmental iodine deficiency

  33. Iodine Deficiency Disorders & Human Life Cycle • Unborn Child (Foetus) • Newborn Child (Neonate) • Child & Adolescent • Adult

  34. Brain Cell Growth Iodine Sufficiency Iodine Deficiency Iodine Deficiency is the single most common cause of preventable mental retardation

  35. Iodine Deficiency & Learning Abilities School age children living in iodine deficient environment on an average, have 13 I.Q. points less than those living in iodine sufficient environments

  36. Implications of Loss of I.Q. • Poor Scholastic performance • Frequent failures / grade repetitions • Absenteeism / Drop outs • Major implications: Education for All • Consequent economic & social effects • Drain on Human Resource Development

  37. IDD – The Hourglass Historic View Iodine Deficiency = Goitre = Visible Swelling No Pain = Not a cause of Mortality = Cosmetic problem Cretinism rare Mental & Physical growth Loss of Energy-hypothyroidism Learning Disability, Poor Motivation Child Development and Child Survival Human Resource Development Current View
