Abstract Objectives This study examined the effect of dietary patterns and engagement in cognitive stimulating lifestyle (CSL) behaviors on the trajectory of global cognition, executive function (EF), and verbal episodic memory (VEM). Methods Western and prudent dietary patterns were empirically derived using food frequency questionnaire responses from 350 community-dwelling older adults (mean age: 73.7 years) participating in the Quebec Longitudinal Study on Nutrition and Successful Aging. CSL was represented by a binary composite indicator based on education, occupational complexity, and social engagement. Global cognition, EF, and VEM were assessed prospectively. Results Primary effect models revealed an association between higher Western dietary pattern score and a greater rate of decline in global cognition and EF. Higher Western dietary pattern adherence was also associated with poorer baseline VEM. Primary effect models also revealed that CSL was independently associated with baseline global cognition and EF. Effect modification models suggested an interactive effect between Western dietary pattern and CLS on global cognition only. No associations were found for prudent dietary pattern score. Discussion Contributing to existing research supporting the negative impact of consuming an unhealthy diet on cognitive function, the current study suggests increased vulnerability among older adults who do not engage in a CSL. These findings can inform the development of lifestyle intervention programs that target brain health in later adulthood.

Objective: To describe the associations between dietary patterns with nutrient intakes differentiated by sex and race. Methods: Cross-sectional study of 71751 subjects (mean age 59 years, 65% female, 76% white) from the Adventist Health Study 2. Participants completed a 204-item validated semi-quantitative food frequency questionnaire. Five dietary patterns were established: non vegetarian, semi vegetarians, pesco vegetarians, lacto ovo vegetarians and strict vegetarians. ANCOVA and linear regression analysis were used to determine differences of nutrient intakes by dietary patterns. Non-dietary variables, such as age, smoking and physical activity were taken into account and associations between dietary pattern and BMI were compared. Analysis was repeated by stratifying for sex and race. Results: Strict vegetarians had the lowest BMI, with graded higher BMI levels for dietary patterns with greater fractions of animal plant protein, total fat and saturated fatty acids but similar total caloric intakes. Mean nutrient intake was more dissimilar across dietary pattern than between the sexes or blacks and whites. In general nutrient intakes were more similar between males and females than between blacks and whites with blacks revealing a strikingly higher percentage of non vegetarians than whites. Supplement intakes were often markedly higher in females than in males and higher in whites than in blacks with mean micronutrient intakes for all dietary patterns being well above the estimated average requirements for American adults in both sexes and blacks and whites. Conclusions: All groups met current American nutrient requirements. Nutrient intakes varied more markedly between dietary pattern than between sex or race. Lower BMI levels were associated with dietary patterns characterized by higher plant food intake despite generally similar caloric intake across dietary patterns warranting further investigation.

Abstract Background: Consumption of a prudent dietary pattern rich in healthy nutrients is associated with enhanced cognitive performance in older adulthood, while a Western dietary pattern low in healthy nutrients is associated with poor age-related cognitive function. Sex differences exist in dietary intake among older adults; however, there is a paucity of research examining the relationship between sex-specific dietary patterns and cognitive function in later life. Methods: The current study aimed to investigate sex differences in the relationship between sex-specific dietary pattern adherence and global cognitive function at baseline and over a 3-year follow-up in 1268 community-dwelling older adults (Mage=74 years, n = 664 women, n = 612 men) from the Quebec Longitudinal Study on Nutrition and Successful Aging (NuAge). A 78-item Food Frequency Questionnaire was used to estimate dietary intake over the previous year. Sex-specific dietary pattern scores were derived using principal component analysis. Global cognition was assessed using the Modified Mini-Mental State Examination (3MS). Results: Adjusted linear mixed effects models indicated that a healthy, prudent dietary pattern was not associated with baseline cognitive performance in men or women. No relationship was found between Western dietary pattern adherence and baseline cognitive function in women. Among men, adherence to an unhealthy, Western dietary pattern was associated with poorer baseline cognitive function (b = -0.652, p = 0.02, 95% CI [-1.22, -0.65]). No association was found between prudent or Western dietary patterns and cognitive change over time in men or women. Conclusions: These findings highlight the importance of conducting sex-based analyses in aging research and suggest that the relationship between dietary pattern adherence and cognitive function in late life may be sex-dependent.
