IMPACT OF LIFESTYLE DISEASES

- United States Data - 2004

• 12% attributed to lack of exercise

- American Heart Ass, 2004

C a r d i o v a s c u l a r D i s e a s e - 3 6 . 3 %

ALL DEATHS

IMPACT OF DIABETES

Diabetes increases the risk of coronary events :-• Two-fold in men• Four-fold in women

- ADA 2002, Diabetes Care 25:S71-73

DIABETES A TICKING TIME BOMBOver the next 24 hours:

2200 diabetics will be diagnosed

512 diabetics will die

66 diabetics will go blind

77 diabetics will be diagnosed with ESRD

153 – diabetes related amputations will be performed

Centre for Disease Control and Prevention. 2000

IMPACT OF KIDNEY DISEASE….

Risk of dying is 100 times more in a 20 year old with kidney disease as compared to a healthy 80 year old

-Oxford Textbook of Clinical Neph, 3rd Ed, (2005)

IMPACT OF METABOLIC SYNDROME

Metabolic Syndrome (Syndrome X) rated as equivalent to smoking in magnitude of risk for Coronary Artery Disease.

Four fold risk of Death from CAD- National Cholesterol Education Program /

Adult Treatment Panel III (NCEP / ATP III)

Major impact on CVS, CNS, CKD

Clinical Criteria for Metabolic Syndrome

3 / 5 needed – NCEP, Circ. 166:3143 – 3421, 2002

Metabolic Syndrome

Waist CircumferenceMen > 102 cm (40 inch)

Women > 88 cm (35 inch)

BP 130 / 85 mm Hg

FBS 110 mg / dl

HDL Chol. Men < 40 mg/dl Women < 50 mg/dl

Triglycerides 150 mg/dl

Pathogenesis of Metabolic Syndrome

Prevalence of Metabolic SyndromeLooking at various studies around the world the prevalence varies from 8% (India) to 24% (United States) in men and from 7% (France) to 46% (India) in women.

Legend: Prevalence of MS 13% in Jaipur and 41% in Chennai.The prevalence of obesity was quite similar (31% versus 33%). Prevalence of elevated triglycerides (46% vs. 30%), hypertension (55% vs. 39%) and elevated fasting plasma glucose (27% vs. 5%).

CLASSIFICATION OF BP FOR ADULTS 18 YEARS

(Mean of 2 or more seated B.P readings on each of 2 or more office visits)

NORMAL : SBP < 120 AND DBP <80 PREHYPERTENSION: SBP = 120 – 139

OR DBP = 80 – 89 STAGE 1 HYPERTENSION: SBP = 140 – 159

OR DBP = 90 - 99 STAGE 2 HYPERTENSION: SBP 160 OR

Benefits of lowering BP ….

10 mmHg reduction of SBP over 10 years will prevent 1 in 10 deaths!!!

IMPACT OF LIFE–STYLE MODIFICATIONS ON HTN ….

LIFESTYLE CHANGES

Diet ExerciseBehaviour

The DASH Diet: -

Salt – 6gm/day

High K+, High Ca++

Low fat, low Cholesterol Less alcohol, less coffee

(Equivalent to one Anti – HTN drug)

- National Heart,Lung and Blood Institute (USA) –2003

“To date, the only intervention to delay aging is caloric restriction by 30-40%. This has been proved conclusively in rodents but not yet in humans”

- Resnick et al, Harrison’s Principles of

Internal Medicine 16th Ed. Pp.44(2005)
