Living Longer and Better:

The Health Experience of California Seventh-day

Adventists.

Larry Beeson, DrPH Associate Professor

School of Public HealthCo-investigator, AHS-2

Adventist Health StudyBackground

More than 95% of the half-trillion health care dollars ($500,000,000,000) in the U.S. each year goes to treat rather than prevent disease

Issues in Science & Technology

Epidemiology: The study of the distribution (who, when, where) and causes (determinants) of health and disease in populations.

Nutritional Epidemiology: The study of diet as promoting or preventing the onset of disease.

Biomedical Research

Epidemiologic evidence suggests that choosing carefully and eating a well-balanced diet, you may reduce your cancer risk:

1. Eat a variety of foods every day

2. Include fresh fruits and vegetables, especially those high in vitamin A and C

3. Choose leafy green and yellow-orange vegetables

4. Keep intake of all fats low (both sat. & unsaturated)

5. Limit your use of butter, margarine, cream, shortening

6. Avoid hidden fats in salad dressing and snack foods

7. Choose lowfat or skim milk and lowfat cheeses

8. Choose fruit instead of high fat desserts

9. Eat foods with fiber for example:

a) Whole grain breads

b) Raw fruits and vegetables

c) Beans, Peas, Seeds

10. Do not drink alcohol in excess

11. Do not smoke

Cancer PreventionPublic Health ServiceNational Institutes of Health

Can we observe measurable health benefits in a people (e.g. SDAs) who have been practicing for more than 140 years the current recommendations of health-related organizations (ACS, AHA, CDC, NIH) ?

Question

Adventist Literature

“Animals are becoming more and more diseased, and it will not be long until animal food will be discarded by many besides Seventh-day Adventists … The Lord will teach many in all parts of the world to combine fruits, grains, and vegetables into foods that will sustain and will not bring disease.”

1902 - Vol 7, Testimonies, pg 124-6

Adventist Literature

“Seventh-day Adventists are handling momentous truths. More than forty years ago [<1869] the Lord gave us special light on health reform, but how are we walking in that light? … On the subject of temperance we should be in advance of all other people.”

1909 - Vol 9, Testimonies, pg 158

Adventist Literature

“In this age of the world the use of tobacco is almost universal. Women and children suffer from having to breathe the atmosphere that has been polluted by the pipe, the cigar, or … the tobacco-user. Those who live in this atmosphere will always be ailing.”

1882 - Vol 5, Testimonies, pg. 440

Adventist Literature

“The liability to take disease is increased tenfold by meat eating.”

1868 - Vol 2, Testimonies, pg 64

Adventist Literature

“Health is a treasure. Of all temporal possessions it is the most precious. Wealth, learning, and honor are dearly purchased at the loss of the vigor of health. None of these can secure happiness, if health is lacking.”

1890 - Christian Temperance andBible Hygiene, pg 150

Adventist Literature

“Fruits, grains, and vegetables, prepared in a simple way, free from spice and grease of all kinds, make … the most healthful diet.”

1870 - Vol 2, Testimonies, pg. 369

Adventist Literature

“It is a mistake to suppose that muscular strength depends on the use of animal food. The needs of the system can be better supplied, and more vigorous health can be enjoyed, without its use.”

1905 - Ministry of Healing, pg. 316

Adventist Literature

“Education in health principles was never more needed than now… Many transgress the laws of health through ignorance, and they need instruction. But the greater number know better than they do. They need to be impressed with the importance of making their knowledge a guide for life.”

1905 - Ministry of Healing, pg. 126

Seventh-day Adventists will continue to be a unique population

for epidemiologic study

1. They are interested in health, hence cost effective postal contacts are likely to

produce good response rates.

2. There are few subgroups in society that have the same range of exposures such as diet. This should increase statistical power in testing hypotheses.

3. The relative absence of cigarette smoking and alcohol consumption allow examination of the effects of other exposures (e.g. diet) without the potential confounding of tobacco and alcohol.

4. The church structure (i.e. “letters of transfer”)

facilitates the tracking of subjects who move after initial enrollment in a study thus minimizing lost-to-followup.

5. Marked tendency towards vegetarianism makes this population probably the closest of any subgroup to the lifestyle

recommendations of several official bodies seeking to prevent cancer and atherosclerotic vascular disease.

1) Measures of association between exposure and health outcome:

“Relative Risk” = “Risk Ratio” = “RR”

2) Statistical significance Biologic significance ??

“p-value”

Brief Introduction to Epidemiology

The Relative Risk (RR)

Incidence of disease (in those “exposed”)

Incidence of disease (in those “not exposed”)RR =

If: RR is less than (<) 1, then exposure is reduces risk of disease

If: RR is equal to (=) 1, then exposure is unrelated to disease

If: RR is greater than (>) 1, then exposure increases risk of disease

High

Lowor

Statistical Significance: (p-value)

p (probability)-value: The probability that an observed value from a statistical test (e.g. RR) could have occurred by chance, if the comparison groups were really alike.

In biomedical research (i.e. Epidemiology), we traditional say that if the p-value is less than (<) 5%, then another explanation (e.g. biology) is a better explanation of the observation than is chance alone.

Meat seems to be one of the “villains” associated with

• Coronary Heart Disease (CHD)

• Colon cancer

• Bladder cancer

• Ovarian cancer

Summary1. As a group, risk of CHD is much lower in

Adventists but this is especially so below the age of 70 years.

2. Risk of many cancers is also much lower, and this is not all explained by the absence of cigarette smoking in Adventists.

3. Adventist men and women in California live much longer that other Californians, this being especially true of the vegetarians.

4. Adventists often have unusual dietary habits that trend toward vegetarianism.

5. Age at virtually all common causes of death is greater by several years.

Summary Cont’d

6. Individual foods that change risk are technically difficult to identify, but the following are probable associations.a) Nuts, and whole grain bread consumption decrease risk

of coronary heart disease (CHD). b) Meat consumption probably increases risk of CHD particularly in younger and middle-aged subjects. c) Fruits, legumes (including soy-products), and tomatoes probably decrease risk of several cancers. d) Meat consumption probably increases risk of colon, ovary, bladder and perhaps other cancers. e) This list by no means exhausts the possibilities.

CONCLUSION

The studies on Adventists in California suggest that a vegetarianlifestyle reduces the risk of many chronic diseases such as:

• CHD• Cancer• Obesity• Arthritis• Diabetes

SummaryAHS “Firsts”

1. The AHS was the first epidemiologic study to demonstrate that men who consumed tomatoes & tomato products frequently, importantly reduced their risk of prostate cancer. (Is it licopenes alone or the complexity of the food ???)

SummaryAHS “Firsts”

2. The AHS was the first study to demonstrate that eating nuts 5 or more times per week appears to significantly reduce the risk of definite fatal CHD and definite nonfatal myocardial infarction compared to eating nuts less than once a week. Similar findings were seen for eating whole wheat bread.

SummaryAHS “Firsts”

3. AHS was the first to demonstrate that intake of adequate amounts of water each day may significantly reduce the risk of fatal coronary heart disease (CHD). This observed protection in both males and females was independent of other established CHD risk factors.

Summary

4. Those who consume a wide range of fruits, vegetables, seeds, whole grains, and nuts have less disease than those who follow a typical American diet.

Summary

5. Vegetarians appear to be at lower risk than omnivores for several fatal chronic diseases:

a) Cancers of the colon, breast, prostate

b) Cardiovascular disease

c) Diabetes

Summary

6. Vegetarians have more favorable heart disease risk profiles:

a) Decreased blood pressure

b) Decreased serum cholesterol

c) Decreased prevalence of obesity

Summary

7. Cancer risk may be lower because of several factors:

a) Increased plant sterol/cholesterol ratio in the diet

b) Decreased primary/secondary bile acids ratio

c) Favorable dietary factors, including more fiber and less fat
