4 ® Body Mass Index (BMI) BMI = Weight (in kg) Height 2 (in meters) BMI = Weight (in kg) Height 2 (in meters) Lbs/ inches 2 x 703 Lbs/ inches 2 x 703 A BMI of A BMI of <25 = desirable 25 – 29.9 = overweight >30 = obese

5 ®

6 ® Relationship of BMI to Excess Mortality 20-40yoa 300 Age at Issue Bray GA. Overweight is risking fate. Definition, classification, prevalence and risks. Ann NY Acad Sci 1987;499: Mortality Ratio Body Mass Index (kg/[m 2 ]) Low Risk 4035 High Risk Moderate Risk

7 ® BMI & Obesity Sample size and weight status NHE S I NHANE S I NHANE S II NHANE S III NHANE S NHANE S NHANE S NHANE S NHANE S Sample (n)6,12612,91111,76514,4683,6033,9163,7563,8354,881 Overweight (25 BMI < 30) Obese (BMI 30) Extremely obese (BMI 40) The 773 morbidly obese female members had used a mean of $11,145 in medical insurance expenses in the year 2003 versus a mean of $8,096 for the other 106,908 adult women (27% higher). Similar values for the men were $16,720 for the 138 morbidly obese men versus $5,943 for the other 82,490 men. (64% higher)

8 ® While BMI certainly tells us how unhealthy a person is, it doesnt tell us how healthy a person is. Example, a skinny fat person aka sarcopenic obesity

9 ® #1 Biomarker of Aging... no decline with age is as dramatic or potentially more significant than the decline in lean body mass. J Nutr 127:990S-991S (1997)

10 ® Over a lifetime 30% of muscle mass is lost Over a lifetime 30% of muscle mass is lost From age 20, women lost 5 – 7 lbs of decade From age 20, women lost 5 – 7 lbs of decade 25% weight loss on a typical diet is muscle 25% weight loss on a typical diet is muscle One lb of muscle burns at least 3Xs the calories as one lb of fat One lb of muscle burns at least 3Xs the calories as one lb of fat Body Fat

11 ® Biochemistry of Vitamin D

12 ® What is a vitamin? Organic compound Required to support life Generally a co-factor for enzyme activation (most B vitamins) or antioxidant (E and C) Must be obtained from the diet Cannot be synthesized in adequate quantities

13 ® Vitamin D, on the other hand… Can be synthesized in the body Has receptors and target tissues …More accurately characterized as a pro-hormone Since it is synthesized by the body from cholesterol, it is not necessarily essential that it be supplied by diet.

14 ® Historical understanding of vitamin D Fundamental to calcium and phosphorus metabolism Deficiencies/insufficiencies related to: Rickets Osteomalacia Osteoporosis 400 IU/day is currently the RDI The amount shown to prevent rickets

15 ® Vitamin D is called the sunshine vitamin It is manufactured in the skin from cholesterol upon exposure to UV radiation. Healthy (RDI) levels of vitamin D production can be achieved by: minutes of sun exposure Hands, forearms and face 3-5 times per week Spring, summer fall months only

16 ® Dietary vitamin D is found in two forms: Vegetable Ergocalciferol/D 2 Manufactured from the plant sterol ergosterol Synthetic form of the vitamin Animal Cholecalciferol/D 3 Manufactured from cholesterol Both can be converted to active hormone 1,25-(OH) 2 D 3, (also called calcitriol) via a two-step hydroxylation first in the liver, then in the kidneys. May also be hydroxylated in the colon, breast, lungs and prostate.

17 ® Look a bit closer and vitamin D gets more interesting… Vitamin D regulates uptake of calcium from the gut through stimulation of gene expression Activating the production of calcium-binding proteins such as calbindin that increase calcium absorption. Upwards of 200 genes are believed to be regulated by Vitamin D, most of which are not involved in mineral metabolism. Essentially every tissue and cell in the body has a vitamin D receptor.

18 ® Blood levels of vitamin D below 20 ng/mL led to 30-50% increased risk of developing and dying from various cancers (colorectal, breast, prostate etc.) Low 25(OH)D levels are associated with all-cause mortality and even more pronounced with cardiovascular mortality Women with blood vitamin D level <12 ng/mL had a 253% increased risk of colerectal cancer Highest levels of vitamin D consumption correlated with a 50% lower risk of breast cancer. Teenagers with frequent sun exposure had a 35-40% reduced risk of breast cancer as adults.

19 ® Theres more… Low sun exposure for the first 10 years of life doubles the risk to multiple sclerosis development. Children receiving ~2000 IU of vitamin D daily had 78% reduced risk to development of type I diabetes. Vitamin D lowered BP to normal levels Low blood vitamin D level is associated with depression, autoimmune disease, osteoarthritis, increased susceptibility to infection, even postulated as a cause of seasonal cold and flu.

20 ® Today, a number of factors have contributed to what one researcher calls a deficiency pandemic of vitamin D Aggressive campaign to use sunscreen has led to a significant segment of the population with vitamin D deficiency Use of sunscreen results in a 99% reduction of vitamin D production Fewer people get out in the sun regularly Fear of skin cancer Work location/habits (garage to car to office to car to garage) Changing perceptions of beauty Aging and skin tone reduce the efficiency of vitamin D synthesis People of color require 5-10 times longer sun exposure compared to Caucasians to make the same amount of vitamin D

21 ® Vitamin D levels in our society An estimated 1 billion people worldwide are thus considered deficient Adults >65 52% of postmenopausal women 36% of young adults had vit D levels <20 ng/mL at the end of winter, in spite of consuming fortified milk or multivitamin daily. In a group of 40 mother-infant pairs tested at birth, 76% of the mothers and 81% of the infants had vit D <20 ng/mL

22 ® Current requirements: <20 ng/mL: deficient <20 ng/mL: deficient ng/mL:insufficient ng/mL:insufficient >30 ng/mL:adequate >30 ng/mL:adequate If insufficient or deficient, it may take >10,000 IU/day to attain adequate levels. If insufficient or deficient, it may take >10,000 IU/day to attain adequate levels.

23 ® To sum up… Vitamin D has evolved into a hormone that is active throughout the body, not only to regulate calcium and bone metabolism, but to control cellular growth, regulate immune function, and control production of insulin and renin among other hormones. All healthcare professionals should be alert to the vitamin D deficiency pandemic. Michael Holick, University of Boston

31 ® How much sugar is in your body 100mgx 10 dl X 5 liters X 1 grams = 5 grams = 1 teaspoon dl liter 1000 mg Normal Fasting Glucose: mg/dl

32 ® A BMJ investigation into the top-selling diabetes drug rosiglitazone (Avandia) raises concerns about its safety and the whole system by which drugs are evaluated, regulated, and promoted around the world. Sept. 7, 2010

33 ® HbA1C Equal to % of RBCs that are glycated Equal to % of RBCs that are glycated You can run but you cant hide from HbA1C because once a RBC is glycated, it stays that way. You can run but you cant hide from HbA1C because once a RBC is glycated, it stays that way. The predictive value of HbA1C for total mortality was stronger than that documented for cholesterol concentration, body mass index and blood pressure. BMJ 2001 The predictive value of HbA1C for total mortality was stronger than that documented for cholesterol concentration, body mass index and blood pressure. BMJ 2001

34 ® HbA1C (%)(mg/dL) 5 97 (76 – 120) (100 – 152) (123 – 185) (147 – 217) (170 – 249) (193 – 282) (217 – 314) (240 – 347)

35 ® Insulin Fasting Insulin Fasting Insulin Increased insulin production causes insulin resistance Hyperinsulinemia is associatd with inflammastion in the brain and triggers increase in plaques that are hallmark of Alzheimers (JAMA 2006) Hyperinsulinemia is associatd with inflammastion in the brain and triggers increase in plaques that are hallmark of Alzheimers (JAMA 2006) The neurodengeration that occurs in AD is linked with abnormal insulin signaling (J Alzheimers Disease 2005) The neurodengeration that occurs in AD is linked with abnormal insulin signaling (J Alzheimers Disease 2005) Insulin resistance also linked to depression, bipolar disease, autism, and schizophrenia. Insulin resistance also linked to depression, bipolar disease, autism, and schizophrenia.

36 ® Lipid Biomarkers Total Cholesterol = HDL + LDL + VLDL Total Cholesterol = HDL + LDL + VLDL HDL = 33% protein, 30% cholesterol, carries cholesterol from the body to the liver HDL = 33% protein, 30% cholesterol, carries cholesterol from the body to the liver LDL = 25% protein, 50% cholesterol, carries cholesterol to the body from the liver LDL = 25% protein, 50% cholesterol, carries cholesterol to the body from the liver

37 ® Tidbits Cholesterol Endogenous > Exogenous South African egg farmers consume 1,240 mg per day, their average cholesterol is (RDA is 300 mg) NEJM reported on a 88 year old man who ate 25 eggs per day for 30 years, weighed 185 at 62 and had a normal cholesterol level. On the island of Crete, the incidence of CVD is lowest in the world and the average serum cholesterol is over 200. Cholesterol is a necessary molecule in the body and accounts for over half the weight of the brains cortex. At least 5% - 7% of statin users experience significant muscle problems.5% - 7% of statin users

38 ® More Tidbits Cardiomyopathy (serious weakening of the heart muscle) is a known adverse and often not reported side effect of statin therapy. Cholesterol is the precursor to all hormones and, therefore, is vital to the many functions of the endocrine system including sexual function. Cholesterol is found in the cell wall of each one of the 70 trillion cells in your body. When cholesterol gets too low, you could suffer from memory loss, sexual dysfunction, low blood pressure leading to dizziness, and loss of libido. Reducing the manufacture of cholesterol in the liver simultaneously reduces the production of Co-Enzyme Q10 - a vital anti-oxidant essential for healthy heart function. (Rather counter productive, dont you think?) Cholesterol is a precursor to serotonin -- a key hormone to feeling good and sleeping well. And last but certainly not least…these cholesterol-lowering drugs DO NOT reduce the deaths due to heart disease. If you dont believe this, just look for this disclaimer on the ads and website of the leading cholesterol- lowering drugs.

39 ® Lipid Biomarkers Lipids, fractionated lipids Lipids, fractionated lipids Total Cholesterol-under 200Total Cholesterol-under 200 Triglycerides-under 150, preferably under 100Triglycerides-under 150, preferably under 100 HDL-over 50 (male) and over 60 (female)HDL-over 50 (male) and over 60 (female) LDL-under 130LDL-under 130 Trig/HDL ratio- under 2.0Trig/HDL ratio- under 2.0 Chol/HDL ratio- under 3.0Chol/HDL ratio- under 3.0 High Tri/HDL – predicts heart attack 17X often (AHA 1995) High Tri/HDL – predicts heart attack 17X often (AHA 1995)

40 ® C – reactive protein CRP is a protein found in the blood, the levels of which rise in response to inflammation. CRP rises up to 50,000-fold in acute inflammation, such as infection. It rises above normal limits within 6 hours, and peaks at 48 hours. Its level is mainly determined by the rate of production (and hence the severity of the precipitating cause). Levels above 2.4 mg/l has been associated with a doubled risk of a coronary event compared to levels below 1 mg/l. CRP & Statins: "the number of patients who would need to be treated with Crestor for 2 years to prevent the occurrence of one primary end point is 95, and the number needed to treat for 4 years is 31." In other words, after four years of treatment, out of every 31 patients, one cardiovascular event would be prevented. Physical fitness is inversely related to CRP level in children and that this relationship is more pronounced in boys than in girls. (Pediatrics 2003) Insulin resistance and C-reactive protein (CRP) levels are strongly correlated in adults
