Background: Many studies have focused on the association between diet and cognitive function. While a subset of these studies focused on a diet that includes tree nuts (TN), there is limited data on the association between peanut and peanut butter consumption (P/PB) and cognitive health. Objective: This study investigated the association of P/PB consumption and cognitive function. Design: This was a cross-sectional study using 2011-2014 NHANES data. Participants/setting: Individuals 60-80 years old in 2011-2014 NHANES who had two 24-hour dietary recalls, cognitive function tests, and education level and with no history of stroke. Measurements: P/PB and TN consumption was measured as well as participant performance on the CERAD Word Learning subtest (CERAD W-L), Animal Fluency test (AFT), and the Digit Symbol Substitution test (DSST). Scores from the three cognitive tests were dichotomized. Individuals were classified as either P/PB consumers or non-consumers and TN consumers or non-consumers. Logistic regression models examined associations between P/PB consumption, tree nut consumption, and cognitive function with adjusted models including age, sex, and education as covariates. Results: A total of 2,454 adults, aged 60-80 years old (mean age=69.4) participated. Approximately half were male (48%), 18% were P/PB consumers, and 14% consumed TN. Participants who did not consume P/PB were more likely to do poorly on the CERAD W-L (adjusted OR=1.56, 95% CI 1.24-1.97; p<0.05), AFT (adjusted OR=1.29, 95% CI 1.03-1.61; p<0.05), and DSST (adjusted OR=1.43, 95% CI 1.12-1.82; p<0.05) when compared to those who did consume P/PB. Conclusions: These findings suggest an association between P/PB consumption and cognitive function; however, this is a cross sectional study and a causal relationship cannot be established. More studies are needed to determine causality.

Abstract Background: Gait is associated with cognitive function and is a trait marker of dementia; however, research on gait and cognitive function usually concentrates on several individual gait parameters. This study used wearable sensors to measure gait parameters in different aspects and comprehensively explored the association of gait with global cognitive function and domain-specific cognitive function.Methods: The data of this cross-sectional study were obtained from 236 community-dwelling Japanese older adults (125 men and 111 women) aged 70–81 years. Gait was measured by asking participants to walk a 6-meter course and back using the Physilog® sensors (GaiUp®, Switzerland). Global cognitive function and cognitive domains were evaluated by face-to-face interviews using the Japanese version of the Montreal Cognitive Assessment. Twenty gait parameters were summarized as independent gait factors using factor analysis. A generalized linear model and linear regression model were used to explore the relationship of gait with global cognitive function and domain-specific cognitive function adjusted for several confounding factors.Results: Factor analysis yielded four gait factors: general cycle, initial contact, propulsion, and mid-swing. Among them, general cycle factor was significantly associated with global cognitive function (β=-0.565, [-0.967, -0.163]), executive function (P=0.012), and memory (P=0.045); initial contact was associated with executive function (P=0.019).Conclusion: Better gait was related to better cognitive function, especially the general cycle, which was correlated with both global and domain-specific cognitive function. The predictive value should be examined in future cohort studies.

Abstract Background Falls are one of the most serious health problems among older adults. Sarcopenia is characterized by a decrease in muscle mass, strength, and physical function. Due to potentially age-related conditions, both falls and sarcopenia have common risk factors. However, the association between sarcopenia and falls is controversial. Moreover, the sex differences in the impact of sarcopenia on falls is not yet clear. This study aimed to investigate the sex differences in the impact of sarcopenia, defined by the Asian Working Group for Sarcopenia (AWGS), on falls in Korean older adults. Methods In this cross-sectional study, we used data from the Korean Frailty and Aging Cohort Study; 2323 community-dwelling older adults (1111 males and 1212 females) aged 70–84 years were recruited in this cross-sectional study. To evaluate sarcopenia, the AWGS diagnostic algorithm was used. We compared the faller and non-faller groups. We performed unadjusted and fully adjusted logistic regression analyses to evaluate the relationship between sarcopenia, falls, and fall-related fractures. Results A total of 239 (24.1%) females in the faller group had a history of falls in the past year, which was statistically higher than that in males (176, 15.8%). In the fully adjusted model, handgrip strength (odds ratio [OR] = 1.508, 95% confidence interval [CI] = 1.028–2.211), and short physical performance battery (OR = 2.068, 95% CI = 1.308–3.271) were significantly lower in the male faller group. However, in the fully adjusted model, the female faller group only showed a significantly low appendicular skeletal muscle mass index (OR = 1.419, 95% CI = 1.058–1.903). Conclusions This large cohort study aimed to identify the sex differences in the incidence of sarcopenia in the older Korean population, using the AWGS diagnostic algorithm, and its correlation with falls and fall-related fractures. The incidence of falls did not increase in the sarcopenia group. Among the sarcopenia components, sex differences affect the history of falls. Therefore, when studying the risk of falls in old age, sex differences should be considered.

Background Normal-height children generally have better cognitive function than growth-stunted, short-stature children. Children’s cognitive function reportedly improves with stimulation. However, a correlation between stimulation and cognitive function in children with a history of short stature remains unclear. Objective To assess correlation between stimulation and cognitive function in normal-height vs. short-stature preschool children. Methods A cross-sectional study with consecutive sampling was performed in four sub-district areas in Jakarta. Preschool-aged children and their primary caregivers from previous studies on short stature were eligible for inclusion. An Indonesian version of a questionnaire was used to assess stimulation. A psychologist assessed verbal IQ (VIQ), performance IQ (PIQ), and full-scale IQ (FSIQ) with the Indonesian version of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). Data were analyzed using Pearson’s correlation and Chi-square tests, and P values <0.05 were considered to be significant. Results Of 62 subjects, 64.5% had normal height and 35.5% had short stature. Both normal-height and short-stature children had similar IQ outcome and history of stimulation. The stimulation was significantly correlated with FSIQ in normal-height children (r= 0.316; P=0.047), but not short-stature children (r=0.049; P=0.828). However, the percentage differences in VIQ, PIQ, and FSIQ between normal-height and short-stature children were not significant (P=0.409, 0.119 and 0.877, respectively). Conclusion  There is a significant correlation between stimulation and IQ in normal-height children. Short-stature preschoolers were not worse in terms of IQ than normal-height preschoolers. Parents and caregivers should be encouraged to provide regular and adequate stimulation to their young children.

Abstract Objectives This study investigated the association of peanut and peanut butter (P/PB) consumption and cognitive function. Methods Using 2011–2014 NHANES data, we selected 60–80 year-olds who had two 24-hour diet recalls, cognitive function tests, and education information. P/PB and tree nut (TN) consumption was measured as well as the participant's performance on the CERAD Word Learning subtest (CERAD W-L), Animal Fluency test (AFT), and the Digit Symbol Substitution test (DSST). Scores from the three cognitive tests were dichotomized. Individuals were classified as either P/PB consumers or non-consumers and TN consumers or non-consumers. Unadjusted and adjusted logistic regression models examined associations between P/PB consumption, TN consumption, age, gender, education and cognitive function. Results Among the 2,857 individuals examined, participants who did not consume P/PB were more likely to do poorly on the CERAD W-L (adjusted OR = 1.55, 95% CI 1.25–1.92), AFT (adjusted OR = 1.30, 95% CI 1.06–1.60), and DSST (adjusted OR = 1.37, 95% CI 1.10–1.71) when compared to those who did consume P/PB. Conclusions These findings suggest an association between P/PB consumption and cognitive function. Funding Sources The Peanut Institute provided funding.
