To examine the risk of dementia, researchers included a group of 133,771 people with an average age of 49 who did not have dementia at the start of the study. They were followed up to 43 years. Of this group, 11,173 people developed dementia. Participants completed a food diary every two to four years, listing what they ate and how often. Researchers defined processed red meat as bacon, hot dogs, sausages, salami, bologna and other processed meat products. They defined unprocessed red meat as beef, pork, lamb and hamburger. A serving of red meat is three ounces, about the size of a deck of cards. Researchers calculated how much red meat participants ate on average per day. For processed red meat, they divided participants into three groups. The low group ate an average of fewer than 0.10 servings per day; the medium group ate between 0.10 and 0.24 servings per day; and the high group, 0.25 or more servings per day. After adjusting for factors such as age, sex and other risk factors for cognitive decline, researchers found that participants in the high group had a 13% higher risk of developing dementia compared to those in the low group.

This large study is a collaboration funded by the National Institutes of Health to NYU Langone Health and includes authors from Johns Hopkins University and other U.S. institutions. The new study relies on information gathered from the ongoing Atherosclerosis Risk in Communities Neurocognitive Study (ARIC-NCS), which since 1987 has closely tracked the vascular health and cognitive function of nearly 16,000 participants as they age. ARIC-NCS is also, the researchers say, the longest-followed cohort of African Americans for researching cognition and heart health. Published in the journal Nature Medicine online January 13, the study concludes that from 1987 until 2020, there were 3,252 study participants who were documented as having developed dementia. This translates to an overall lifetime risk for dementia among middle-aged Americans of 42 percent, which is an average of the 35 percent risk in men and the 48 percent risk in women. The excess risk in women was largely due to their lower death rates.
