Trends & Projections of NCDs in India

Diabetes• 2000: 32 million (WHO)• 2010: 51 million (International Diabetes Federation)• 2030: 80 million (WHO)

Cardio-vascular Diseases• 1998: 19 million (ICMR)• 2005: 38 million (Nat. Com. Macroeconomics & Health)• 2015: 64 million (Nat. Com. Macroeconomics & Health)

Cancer• Estimated number of persons with cancer: 2.8 million• Annual Incidence: 1 million

Disease Burden due to NCDs

• More than 20% of the population have at least one chronic disease

• More than 10% have more than one chronic disease

Mortality estimates due to NCDs

• Globally all deaths (2005) 58 million*• Globally deaths due to NCD (2005) 35 million*

(60.3%)

• All deaths in India (2004) 10.3 million #

• Deaths due to NCDs in India (2004) 5.2 million # (50.5%)

Cancer Scenario: India

• Incidence: 10 lakhs /yr• Prevalence: 28 lakhs• Deaths from cancer: 5 lakh / year • Age group affected: 60-70% in 35-64 years • Tobacco related cancers about 40 %• 2/3rd cases in advance stage at the time of

diagnosis

• Common Cancers Breast, uterine cervix & oral cavity in females Oral cavity, lung & oesophagus in males  

Gaps in the natural history of NCDWeb of causation

Changes in life style stress

Abundance of food lack of physical activity smoking emotional

disturbance

aging

Obesity hypertension

Hyperlipidemia thrombotic tendency

changes

artery walls

Coronary arthrosclerosis coronary occlusionMyocardialinfarction

Gaps in the natural history of NCD3. Long latent period: it is the period

between the first exposure to suspected cause and the eventual development of disease. This makes it difficult to link suspected causes with outcomes.

4. Indefinite onset : Most (NCD) are slow in onset and development. Distinction between diseased and non diseased may be difficult to establish.

Prevention of NCDLevels of prevention1. Primordial

2. Primary

3. Secondary

4. Tertiary

1. Primordial prevention- Prevention of the emergence or development of risk factors in countries or population groups in which they have not yet appeared. Efforts are directed towards discouraging children from adopting harmful life styles.

2. Primary prevention- Action taken prior to the onset of disease which removes the possibility that the disease will ever occur. Can be divided into population & high risk strategy.

For healthy people

For unhealthy people

Prevention of NCDInterventions:• Health promotion• Specific protection• Adequate nutrition• Safe water and sanitation

3. Secondary prevention-Action which halts the progress of the disease at its incipient stage and prevents complications. Mostly curative. Disadvantage - patient has already suffered mental & physical anguish & community to loss of production. Often more expensive &less effective. Intervention – EARLY DIAGNOSIS AND TREATMENT

4. Tertiary prevention- defined as all measures available to reduce impairments & disabilities, minimize suffering due to departure from good health & promote patient’s adjustment to irremediable conditions.Intervention – DISABILITY LIMITATION AND REHABILITATION

Objectives

1. To prevent and control common NCDs through behavior and lifestyle changes

2. To provide early diagnosis and management of common NCDs

3. To build capacity at various levels of health care facilities for prevention, diagnosis and treatment of common NCDs

4. To develop trained human resource within Public Health set up

5. To establish and develop capacity for palliative & rehabilitative care

Components

• Prevention through behaviour change

• Early Diagnosis

• Medical treatment

• Capacity building of human resource.

• Supervision, monitoring and evaluation

Strategies of Programme

• Promotion of healthy lifestyle through behaviour change

• Opportunistic screening of persons above 30 yrs • Comprehensive examination, diagnosis and

management of cancer, diabetes, cardiovascular diseases and stroke

• Development of trained manpower • Strengthening of tertiary level health facilities • Programme management at centre, state and district

Surveillance, monitoring & evaluation Regular review meetings

Community Awareness • Training of health workers namely ASHA, ANM, and

Male Health Workers

• Health promotion activities in community, school and workplace settings through IPC, education, mass media etc.

• Opportunistic screening using measurement BP for hypertension and blood glucose by strip method for diabetes at community level

• Patient referral cards to facilitate referral & follow-up
