American Journal of Epidemiology . (): -. The objectives of the study were: 1) to evaluate how life expectancies changed in subjects who died from heart disease and all-site cancer from 1960 through 1988 using the Adventist Studies; 2) to compare the life expectancies from heart disease and all-site cancer between vegetarians and omnivores for different ages and calendar times, and separately in males and females. We combined the two cohort studies, the Adventist Mortality Study (AMS, 1960-1985; n = 27,517), and the Adventist Health Study (AHS, 1970-1988; n = 34,192). Life expectancies from specific causes were calculated for subjects who had survived to ages 30, 50, 70, and 80 during three calendar periods: 1960-1969, 1970-1979, and 1980-1988. The basis for the life table calculations was the age disease-specific mortality rates, which were calculated using the Multiple Decrement Life Table Analysis Program (MDLTAP), taking into account competing causes of death and allowing for the control of confounders. We conducted both univariate and multivariate analyses controlling for the potential confounders: education, body mass index (BMI), and exercise. We examined the secular trends in life expectancies using weighted linear regression, where inverse variances obtained from the MDLTAP program were used as weights for the respective calendar periods. During 28 years of follow-up, 2,646 deaths from coronary heart disease, and 1,549 deaths from cancer were identified. The life expectancy for vegetarian and omnivorous males and females who eventually died from heart disease increased with secular time from 1960 to 1988 for all ages. This increase was 4-10 years in females and 2-6 years in males. The life expectancy at all ages of vegetarian females who died from heart disease was 0.5-2.0 years higher than that of omnivores for all the calendar periods. This difference was statistically significant at younger ages during the calendar period 1960-1988. The life expectancy of vegetarian males who died from heart disease was 2-4 years higher than that of omnivores for the calendar periods 1960-1969 and 1970-1979 and this difference was statistically significant at most ages. The life expectancy at all ages of both females and males who eventually died from cancer increased with secular time from 1960-1988, irrespective of their type of diet. This increase was 2-9 years in females and 3-7 years in males. The life expectancy at all ages of vegetarian females who died from cancer was 1-2 years higher than that of omnivores in the calendar period 1970-1979. The difference in life expectancy that was attributed to a vegetarian status in males who died of cancer was 1-4 years. In conclusion, the life expectancy from specific causes of death, increased with secular time from 1960 to 1988, irrespective of gender and type of diet. Vegetarians had 1-4 years greater life expectancy from these causes when compared to omnivores. The gender differences in life expectancy of subjects who died from heart disease or cancer were less in vegetarians compared to omnivores. Among those subjects, a vegetarian diet contributes to greater longevity, and this lifestyle decreases the gender gap in life expectancy in those dying from specific causes of death.
  • Daher N, Lindsted KD, Fraser GE, Zimmerman GJ. "Secular Trends in Life Expectancy by Diet Status among Never Smoking Seventh-day Adventists." American Journal of Epidemiology . (): -. To evaluate how life expectancy changed by age and calendar time from 1960 through 1988, we combined two overlapping cohorts, the Adventist Mortality Study (AMS, 1960-1985, n = 27 530) and the Adventist Health Study (AHS, 1976-1988, n = 34 192). After combining both cohorts, a total of 38,237 subjects were identified with 10 329 deaths. In order to determine the impact of diet on life expectancy, we compared the life expectancy of omnivores to vegetarians separately in never smoking males and females at different ages and different calendar periods. We calculated life expectancies for subjects who had survived to ages 30, 50, 70, and 80 during six calendar periods: 1960-1964, 1965-1969, 1970-1974, 1975-1979, 1980-1984, and 1985-1988. The basis for the life table calculations was the age-specific mortality rates, which were calculated using the Multiple Decrement Life Table Analysis Program (MDLTAP) allowing for the control of confounders for competing causes of death. We conducted both univariate and multivariate analyses controlling for the potential confounders: education, body mass index (BMI), and exercise. We examined the secular trends in life expectancies using weighted linear regression, where inverse variances obtained from the MDLTAP program were used as weights for the respective calendar periods. Life expectancy for both males and females increased with secular time from 1960 to 1988 for all ages. There was a significant linear trend for both males and females at most ages. The trend tended to be steeper in omnivores compared to vegetarians, and females as compared to males. The life expectancy of vegetarian females who had survived to 30, 50, and 70 years of age was 1-2 years higher than that of omnivores for the calendar periods 1965-1969, 1975-1979 and 1980 -1984. The life expectancy of vegetarian males up to 80 years of age was 1-4 years higher than that of omnivores for all calendar periods. Females had a higher life expectancy than males. The gender differences in life expectancy were much less in vegetarians compared to omnivores. We conclude that the life expectancy increased with secular time from 1960 to 1988 in both males and females, and for both vegetarians and omnivores. A vegetarian diet does contribute to greater longevity, and this lifestyle decreases the gender gap in life expectancy.
