By a News Reporter-Staff News Editor at Obesity, Fitness & Wellness Week -- Researchers detail new data in Diet and Nutrition Disorders. According to news reporting from Loma Linda, California, by NewsRx journalists, research stated, "In samples of African Americans and the elderly adults, obesity is often not found to be a risk factor for mortality. These data contradict the evidence linking obesity to chronic disease in these groups."

The news correspondents obtained a quote from the research from the Logan College of Chiropractic, "Our objective was to determine whether obesity remains a risk factor for mortality among long-lived black adults. The Adventist Health Study 2 is a large prospective cohort study of Seventh-day Adventist church members who are encouraged by faith-based principles to avoid tobacco, alcohol, and meat consumption. We conducted an attained age survival analysis of 22,884 U. S. blacks of the cohort-half of whom attained an age of 58-108 years during the follow-up (adult life expectancy of 84 years in men, 89 years in women). Women in the highest body mass index quintile (>33.8) experienced a significant 61% increase (hazard ratio [95% CI] = 1.62 [1.23, 2.11] relative to the middle quintile) in mortality risk and a 6.2-year (95% CI = 2.8-10.2 years) decrease in life expectancy. Men in the highest body mass index quintile (>30.8) experienced a significant 87% increase (hazard ratio [95% CI] = 1.87 [1.28, 2.73] relative to the middle quintile) in mortality risk and 5.9-year (95% CI = 2.1-9.5 years) decrease in life expectancy. Obesity (>30) was a significant risk factor relative to normal weight (18.5-24.9) in never-smokers. Instantaneous hazards indicated excess risk from obesity was evident through at least age 85 years. The nonobese tended to follow plant-based diets and exercise vigorously. Avoiding obesity promotes gains in life expectancy through at least the eighth decade of life in black adults."

According to the news reporters, the research concluded: "Evidence for weight control through plant-based diets and active living was found in long-lived nonobese blacks."
