However, much of the research examining the relationship between sleep and cognition has been primarily focused on non-Hispanic White samples. Thus, there is a severe lack of research on minoritized populations, such as Hispanic/Latin Americans (H/Ls). H/Ls are the largest and one of the fastest growing demographic groups in the US. Compared to non-Hispanic White individuals, they have increased risk for cognitive decline. Therefore, it is critically important to identify modifiable factors to reduce this risk. We sought to provide a review of the current literature on the associations between sleep disturbances and cognitive function in H/L adults. Participants and Methods: We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines that examined the relationship between sleep disturbances and cognitive performance in H/L adults. A total of five databases were used to conduct the search for this review: EMBASE, PsychInfo, Pubmed, Scopus, and Web of Science. Articles that did not meet the following criteria were excluded: (1) examined the association between sleep disturbances and cognitive decline in H/Ls and (2) had a sample with at least 5% H/Ls. Conference abstracts, theses, dissertations, and book chapters were excluded. Results: Nine studies met inclusion criteria and were included in the synthesis of this review. Across the studies reviewed, sleep parameters examined sleep duration, insomnia, sleep onset latency, and sleep-disordered breathing (including obstructive sleep apnea). Four of the five studies addressing sleep duration's impact on cognition suggested extended sleep (approximately 9+ hours) was associated with lower cognitive function, although not equally across cognitive domains; two studies indicated a U-shaped relationship. One study predicted a 7-year cognitive decline due to prolonged sleep. A single study examining sleep onset latency (SOL) suggested that extended SOL related inversely to overall cognitive function. There was evidence to support a link between insomnia symptoms and cognitive decline in 2 of the 4 studies reviewed, where individuals with symptoms of insomnia were more likely to have cognitive impairment. For sleep-disordered breathing, a significant association with cognitive decline was evident in only one of two studies. However, the negative impact of obstructive sleep apnea on cognition was evident in both studies: lower oxygen levels during sleep were linked to reduced cognitive functioning in H/L adults. Conclusions: Our review found equivocal evidence of an association between sleep parameters and cognition in H/Ls with the strongest support found for a relationship between sleep duration and cognitive performance. Heterogeneity in how these parameters were operationalized (i.e., criteria used) and measured (i.e., objectively vs subjectively) may contribute to the ambiguous findings. Our review also identified a need for longitudinal research on these relationships. The field of sleep and cognition in H/Ls remains inadequately explored, underscoring the need for further investigation.

Objective:

Previous research has suggested that the presence of sleep disturbances (e.g., insomnia, sleep disordered breathing) is associated with poorer cognitive performance and increased risk for cognitive impairment. However, much of the research examining the relationship between sleep and cognition has been primarily focused on non-Hispanic White samples. Thus, there is a severe lack of research on minoritized populations, such as Hispanic/Latin Americans (H/Ls). H/Ls are the largest and one of the fastest growing demographic groups in the US. Compared to non-Hispanic White individuals, they have increased risk for cognitive decline. Therefore, it is critically important to identify modifiable factors to reduce this risk. We sought to provide a review of the current literature on the associations between sleep disturbances and cognitive function in H/L adults.

Participants and Methods:

We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines that examined the relationship between sleep disturbances and cognitive performance in H/L adults. A total of five databases were used to conduct the search for this review: EMBASE, PsychInfo, Pubmed, Scopus, and Web of Science. Articles that did not meet the following criteria were excluded: (1) examined the association between sleep disturbances and cognitive decline in H/Ls and (2) had a sample with at least 5% H/Ls. Conference abstracts, theses, dissertations, and book chapters were excluded.

Results:

Nine studies met inclusion criteria and were included in the synthesis of this review. Across the studies reviewed, sleep parameters examined sleep duration, insomnia, sleep onset latency, and sleep-disordered breathing (including obstructive sleep apnea). Four of the five studies addressing sleep duration's impact on cognition suggested extended sleep (approximately 9+ hours) was associated with lower cognitive function, although not equally across cognitive domains; two studies indicated a U-shaped relationship. One study predicted a 7-year cognitive decline due to prolonged sleep. A single study examining sleep onset latency (SOL) suggested that extended SOL related inversely to overall cognitive function. There was evidence to support a link between insomnia symptoms and cognitive decline in 2 of the 4 studies reviewed, where individuals with symptoms of insomnia were more likely to have cognitive impairment. For sleep-disordered breathing, a significant association with cognitive decline was evident in only one of two studies. However, the negative impact of obstructive sleep apnea on cognition was evident in both studies: lower oxygen levels during sleep were linked to reduced cognitive functioning in H/L adults.

Conclusions:

Our review found equivocal evidence of an association between sleep parameters and cognition in H/Ls with the strongest support found for a relationship between sleep duration and cognitive performance. Heterogeneity in how these parameters were operationalized (i.e., criteria used) and measured (i.e., objectively vs subjectively) may contribute to the ambiguous findings. Our review also identified a need for longitudinal research on these relationships. The field of sleep and cognition in H/Ls remains inadequately explored, underscoring the need for further investigation.
