Topic: Risk, prevention and care in population studies
Background Cardiovascular disease and vascular risk factors increase rates of cognitive impairment, but very little is known regarding prevention in this high-risk group. The heart-healthy Mediterranean-type dietary pattern may beneficially influence both vascular and cognitive outcomes. Objectives We examined the association between Mediterranean-style diet and cognitive decline in women with prevalent vascular disease or ≥3 coronary risk factors. Design/participants/setting Prospective cohort study among 2,504 women participants in the Women's Antioxidant Cardiovascular Study (WACS), a cohort of female health professionals. Adherence to a Mediterranean-style diet was determined at WACS baseline (1995-1996) using a 0- to 9-point scale with higher scores indicating higher adherence. In 1998-2000, participants aged ≥65 years underwent a telephone cognitive battery including five tests of global cognition, verbal memory, and category fluency. Tests were administered three additional times across 5.4 years. Statistical analyses performed We used multivariable-adjusted generalized linear models for repeated measures to compare the annual rates of cognitive score changes across tertiles of Mediterranean diet score, as assessed at WACS baseline. Results In both basic- and multivariable-adjusted models, consuming a Mediterranean-style diet was not related to cognitive decline. No effect modification was detected by age, education, depression, cardiovascular disease severity at WACS baseline, or level of cognition at initial assessment. Conclusions In women at higher risk of cognitive decline due to vascular disease or risk factors, adherence to a Mediterranean-style diet was not associated with subsequent 5-year cognitive change.

How this study scored 52/100
Published in a peer-reviewed journal, and it is a cohort study following people over time. Scored zero for sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 30 of the 58 points we could judge it on, which is 52 out of 100.
