Social engagement and its links to cognition differ across non-Hispanic Black and White older adults.

ABSTRACT:

Objective

Racial inequalities in dementia have been linked to disparities in socioeconomic status, chronic diseases, and psychosocial stress. Less focus has been given to psychosocial protective factors. Previous studies suggest that social engagement promotes better cognitive aging, but few have examined whether social engagement or its associations with cognition vary across non-Hispanic Whites (NHW) and Blacks (NHB).

Method

Participants included 465 adults (53% NHB) from the Michigan Cognitive Aging Project (M_age = 63.59 ± 3.15) who completed a comprehensive neuropsychological battery. Social engagement was operationalized as network size, frequency of social activity participation, and social support. Cognition was operationalized using factor scores corresponding to five domains: episodic memory, executive functioning, processing speed, language, and visuospatial functioning. Cross-sectional associations between social engagement and cognitive outcomes were examined using race-stratified regressions controlling for age, sex/gender, education, wealth, marital status, depressive symptoms, and chronic diseases.

Results

There were no racial differences in social network size or social support. NHB participants reported less social activity participation than NHW participants. Social activity participation was positively associated with memory in NHW, but not NHB.

Conclusions

These findings may suggest a threshold effect whereby NHB older adults are less likely to participate in social activities at the level needed to yield cognitive benefits. Lower social activity participation among NHB may reflect structural barriers and/or cultural differences in patterns of social engagement. This study highlights the need to improve measurement of and access to culturally relevant social activities for NHB to combat racial inequalities in cognitive aging.

Project description:ObjectiveResearch suggests a difference in sweet taste perception between non-Hispanic black (NHB) and non-Hispanic white (NHW) adults; however, limited research has examined sweet taste perception in relation to the dietary intake of sweet products. The aim of this study was to examine sweet taste perception and the consumption of sweet foods, beverages, and sugar in NHB and NHW adults, and to evaluate whether sweet taste perception is associated with dietary intake.MethodsThis cross-sectional study examined the association between race, sweet taste perception and sweet food, beverages, and sugar consumption in healthy, NHB and NHW adults. Seven day food records were analyzed in Nutrition Data System for Research software. Intensity of sweet taste perception was tested and the general labeled magnitude scale method was used to facilitate group comparisons. Independent t tests, Mann-Whitney tests, and Pearson correlations were used to assess associations.ResultsParticipants were NHB (n = 98) and NHW (n = 90) adults, 41 ± 1 y of age (mean ± SEM) with energy intake of 2271 ± 53 kcal. Body mass index was higher in NHBs than in NHWs (36 ± 1 versus 32 ± 1 kg/m2, P = 0.048), but no differences were observed in age, energy consumption, or total sugar intake. Sweet taste perception rating (median [interquartile range] NHB: 73.5 [63.9-83], NHW: 52.1 [46.4-57.7]; P = 0.001) and added sugar intake (NHB: 39.4 g/1000 kcal [36.3-42.4], NHW: 30 g/1000 kcal [26.7-33.4]; P < 0.001) were greater in NHB. Perceived sweet taste intensity was positively associated with consumption of servings of sweet products among NHBs (R2 = 0.057, P = 0.018) but not NHWs (R2 = -0.012, P = 0.314).ConclusionsNHBs have a higher intensity of sweet taste perception than NHWs. The positive association of sweet taste perception and sweet product consumption in NHBs suggests that a higher intensity of sweet taste perception may be associated with an increased proportion of energy consumption from added sugars.
