Top 5 Takeaways

1. High Prevalence of SCD Among Caregivers: Approximately 12.6% of unpaid caregivers aged ≥45 years reported subjective cognitive decline (SCD), compared to 10.2% of noncaregivers.
2. Health and Demographic Correlations: Caregivers with SCD were more likely to be employed, men, aged 45–64 years, and have chronic health conditions.
3. Impact on Care Quality: SCD among caregivers could adversely affect the quality of care provided to care recipients.
4. Need for Support: Health care professionals can support caregivers by recognizing SCD-associated challenges and providing compensatory strategies.
5. Public Health Implications: Understanding caregivers’ cognitive health is crucial for maintaining the health and well-being of both caregivers and care recipients.

Summary

This study analyzed data from the 2015-2019 Behavioral Risk Factor Surveillance System (BRFSS) to assess the prevalence and characteristics of subjective cognitive decline (SCD) among unpaid caregivers aged ≥45 years in 22 states. Approximately one in eight caregivers reported SCD, which was higher than the prevalence among noncaregivers. Caregivers with SCD were more likely to report chronic health conditions, a history of depression, and frequent activity limitations.

Methods

The study used a cross-sectional analysis of BRFSS data, a random-digit–dialed telephone survey of noninstitutionalized U.S. adults. Respondents were classified as caregivers if they had provided care to a family member or friend with a health condition or disability in the past 30 days. SCD was identified through self-reported experiences of worsening confusion or memory loss over the past year. Weighted percentages and 95% confidence intervals were calculated using SAS-callable SUDAAN survey procedures.

Discussion

The findings indicate that SCD is more prevalent among caregivers than noncaregivers, particularly among those aged 45-64 years. SCD among caregivers is associated with negative physical and mental health outcomes, suggesting the need for targeted interventions. The study highlights the importance of recognizing and addressing SCD in caregivers to ensure the quality of care provided to care recipients.

Conclusion

As the U.S. population ages, the number of caregivers and care recipients is expected to increase. Understanding the cognitive health of caregivers is critical for supporting their well-being and the quality of care they provide. Health care professionals should be aware of SCD among caregivers and offer appropriate support and resources.
