Is there a relationship between hearing impairment, risk factors for cardiovascular disease, and cognitive function for individuals who identify as Hispanic/Latino?
Stickel and colleagues (2020) addressed this question by analyzing results obtained on 9,180 individuals between the ages of 45-74 years who identified as Hispanic or Latino.
Data collected on these individuals included tests of pure-tone hearing sensitivity, measures of cardiovascular disease risk factors (like body mass index), and cognitive function, as well as sociodemographic factors.
Investigators sorted study participants into four cardiovascular disease risk groups: (1) healthy; (2) typical; (3) high cardiovascular disease risk; and (4) hyperglycemia. As compared to those in the healthy group, individuals in the high cardiovascular disease risk group and with hyperglycemia had a greater risk of hearing impairment (>25 dB pure-tone average of 500, 1000, 2000, and 4000 Hz in the better hearing ear). Hearing impairment also was associated with poorer cognitive function.
They also found an association between high cardiovascular disease risk and poorer cognitive function regardless of hearing impairment status and between hyperglycemia and poorer verbal learning and memory for those with hearing impairment. The authors indicate that these results beg the need for further inquiry for the cause of these associations in this demographic.Review a summary of this work with quotes from the study authors.

“Huh?” is used in at least 31 languages around the world! A version of the word can be found in nearly every language on Earth (Dingemanse et al, 2013). This research concluded that all languages studied included a word similar, in both sound and function, to the English “huh?” Regardless of language, the word is…
If you have a dog or cat, you’ve probably seen their ears moving toward an interesting or startling sound. For professional equestrians, watching the ears of their horse allows them to gauge their shifting attention. Humans still have these same muscles, and even more interesting is their relationship to our brain and how we pay attention. …
Tai Chi is not just for increasing balance; it may also help improve cognitive performance. In a recent randomized controlled trial, study participants who practiced a form of Tai Chi twice a week for six months improved their scores on the Montreal Cognitive Assessment (MoCA) when compared to a control group (Fuzhong et al, 2023)….
