Introduction
From the onset of the COVID-19 pandemic, significant concern existed regarding social isolation of older populations, especially those with cognitive impairment
The issue of caregiving roles is relevant especially amongst the Mexican American (MA) community, where nursing home facilities for aging parents are less likely to be utilized, and “familism” is exhibited at a higher rate than their Non-Hispanic White (NHW) counterparts (Crist et al., 2009) (Falzarano et al., 2022). In Latinx culture, familism, the high importance of a bond among members of a family, cements life-long relationships, provides considerable strength in adverse environments and has been shown to be a protective mechanism against stressors (Umaña-Taylor et al., 2011). In various reviews, familism either shows no association with caregiver burden, or lower degrees of burden (Maximiano-Barreto et al., 2022; Tian et al., 2022). This may indicate that in households with a culture of familism, more time spent between caregiver and recipient can be beneficial for the recipient, and less harmful for the caregiver. Consequently, there may be ethnic differences in caregiver outcomes throughout the duration of the pandemic.
The Brain Attack Surveillance in Corpus Christi- Cognitive (BASIC-C) is a longitudinal prospective cohort study investigating informal caregiving at home and cognitive impairment/dementia in aging populations in a MA and NHW community in Corpus Christi, Texas. The purpose of this paper is to report the project’s findings on MA and NHW caregivers’ roles in caring for their loved ones pre- and during the pandemic, including frequency of interaction, self-reported impact on caregiving ability, and financial changes and burden.
We hypothesized that overall, informal caregivers will report significant changes in their caregiving roles in comparison to before the pandemic. Additionally, it is expected that MA caregivers report less significant changes in their caregiving roles, potentially due to cultural differences like familism.
Methods
The methods of the community-based BASIC-C project were previously reported (Briceño et al., 2020). Briefly, households were randomly identified in Nueces County, Texas, USA, a predominantly urban county with residents living in the city of Corpus Christi. The population estimate was 340,233 in 2020, 14.9% of which are age 65 and older. Of the population aged 65 and older, 50.7% are of Hispanic/Latinx ethnicity, and 43.4% are of non-Hispanic White ethnicity (US Census Bureau, 2022).
Participants and Procedure
Recipients of informal care ≥ age 65 were recruited using a random sample door-to-door addresses from 5/1/2018–3/15/2020. Households were identified by random ascertainment using US Census Data. Recruitment continued after the COVID pandemic onset from 4/20/2020–2/11/2022 using a random sample of phone numbers. Individuals with possible cognitive impairment were identified using the Montreal Cognitive Assessment (MoCA) (Nasreddine et al., 2005) during door-to-door recruitment and Telephone Montreal Cognitive Assessment (T-MoCA) (Katz et al., 2021) during phone recruitment. Participants who scored ≤25 and ≤18 on the MoCA or T-MoCA respectively were eligible for participation. These eligible participants are termed “recipients” for the purposes of our studies. Recipients named a non-paid caregiver who provided them with any level of care, with a very broad definition of “caregiving.” Both the recipient and caregiver answered questions about the recipient’s health and demographics. Recipients took a long form Harmonized Cognitive Assessment Protocol cognitive assessment test (Langa et al., 2020), and caregivers answered additional questions about the recipient.
Beginning in May of 2020, we added on a survey to our caregiver interview regarding the COVID-19 pandemic. The survey included three domains, with nine questions in the first domain for a total of 11 total items. These three domains included: “In what ways throughout the duration of the coronavirus pandemic was your work (paid employment, outside of informal caregiving) affected?”; having them rank the extent to which “COVID-19 has impacted my role as a caregiver,” and “Compared to before the COVID-19 pandemic, I see my [recipient] more than before, less than before, or the same.” These questions were generated from surveys such as the Environmental Influences on Child Health Outcomes survey (Blackwell et al., 2018), and the presentation was similar to the Panel Study of Income Dynamics (McGonagle et al., 2012).
Statistical Analysis
Analyses were performed using data from 395 baseline Informants were comprised of MA or NHW caregivers who also completed the 11-item COVID survey between 5/28/20 and 3/31/22 (153 at baseline interview; 242 at follow-up interview). Missing income and education for one caregiver was imputed using SAS Proc MI. All analyses were performed using SAS version 9.4 (SAS Institute Inc).
Inverse propensity weighting (IPW) (Chen, et al., 2020; Elliott & Valliant, 2017) was used to address selection bias due to sample nonresponse. Population weights were created to calibrate MoCA screen sample demographics to 2015–2019 U.S. Bureau of Census population estimates for Nueces County by age, sex, race, ethnicity, and education level (U.S. Bureau of Census, 2022). Additional IPW adjustments were made to account for attrition of eligible dyads and informants who did not complete the COVID survey.
Unweighted descriptive estimates and population weighted estimates and 95% confidence intervals for caregiver demographics were generated along with weighted percentages of their responses to each of the COVID survey items (9 items covered impact of COVID on work and 2 items asked about COVID impact on caregiver roles). To account for sampling and weight variability, Rao-Scott design-adjusted chi-square was used to test for group differences in caregiver responses to COVID survey items. Ethnic group comparisons (MA vs. NHW) to COVID survey items included comparisons stratified by caregiver household income (< $40,000.00 vs. ≥ $40,000.00) and recipient cognitive status (T-MoCA ≤15 vs. T-MoCA >15). Logistic regression was used to estimate the ethnic effect after adjusting for caregiver’s age, gender, income, relationship with the respondent, and respondent’s cognitive status.
Statement of Ethics
Caregiving recipients recruited to be part of the study who have significant cognitive dysfunction gave their written or verbal assent and written or verbal consent was obtained from their caregiver.

The impact of COVID on caregiver role by ethnicity and income was also examined. For caregivers with an income of less than $40,000 per year, a higher percentage of NHWs (39.4%) compared to MAs (15.3%) reported very/extreme impact on role as a caregiver (X2 (1, N = 395) = 7.57, p < .01). For the impact on work items, for caregivers with a household income of $40,000 or more, a higher percentage of NHWs compared to MAs (26.6% vs. 14.8%, respectively) increased their work hours (X2 (1, N = 395) = 4.1, p < .05). These ethnic differences remained statistically significant after accounting for caregiver’s age, gender, income, relationship with the respondent, and respondent’s cognitive status. Additionally, for caregivers with an income of $40,000 per year or more, a higher percentage of NHWs (47.9%) compared to MAs (30.4%) did not have a paying job before COVID (X2 (1, N = 395) = 6.2, p < .02). However, this effect was no longer significant after adjusting for caregiver’s age and relationship with the respondent in a multivariate model. No other ethnic differences were detected, with or without adjusting for caregiver’s demographics and respondent’s cognitive status.
Discussion
This study found that 20% of caregivers noted “very” or “extreme” changes in their caregiving role during the pandemic, but the remaining 80% reported little or no change. As we navigate life in a post-COVID world, it is important to consider how pandemics may also influence the lives of those caring for the most vulnerable populations. Examining caregiver burden and impact of COVID on the close relation of older adults should influence how we distribute resources, education, and allocation of vaccines and treatments. For the majority of caregivers in our study sample, however, little changed during the pandemic. In this study community only about 15% of caregivers saw their care recipient less than before the pandemic. The same or more time was spent with caregivers, and a majority of caregivers reported their ability to care informally for their recipient was unchanged. This may suggest protection from social isolation although we did not measure recipient social isolation in this study. About a third of caregivers did indicate some change in the amount of time they interacted with their recipient during the pandemic.
Considering the turmoil of the pandemic, this is less change than we expected. Interaction with others is an established protective mechanism for dementia progression (Ying et al., 2020). There is great concern about the 15% of recipients with AD/ADRD that may have been underserved during the pandemic.
There were not many significant differences in the analysis between NHWs and MAs. The significant findings included that NHWs with limited incomes felt more caregiving strain than MAs. This is likely due to MAs already taking on greater caregiving roles than NHWs prior to the pandemic, and therefore feeling less of a difference upon the start of the pandemic (Crist et al., 2009). Familism may also explain the increased impact felt by NHW compared with MA caregivers. Similarly, NHWs report more increased work hours and lack of a paying job prior to the pandemic, however, we did not consider retirement and unemployment in that question. One possible explanation is that NHW caregivers are more likely to be spouses and thus more likely to be retired. Further, while our data does not show an exacerbation of ethnic disparities, MA caregivers have previously reported higher need for financial resources (Mehdipanah et al., 2022). This in conjunction with the literature supporting that minority populations have suffered a disproportionate impact during the pandemic indicates that two mechanisms of inequity could be working at once (Tai et al., 2021).
There are limitations to this study. One limitation is that recipient’s demographics cannot be paired directly to their caregiver’s demographics. It is also not possible to determine whether recipients and caregivers who lived together during the pandemic were living together prior to the pandemic. Further, the results of the COVID survey have a range of explanations and must be considered in the context of the sample answering the questions. None of the COVID-19 survey questions assessed emotional bonds or burden. Additionally, we did not further analyze the time the survey was completed. It is possible that those who answered the survey in the beginning months of the pandemic may have had more of an impact on caregiving than those who answered in later stages.
Our study overall found 20% of caregivers indicated that the COVID-19 pandemic had a “very” or “extreme” impact on their role as a caregiver. Few other differences in caregiving pre- and post-COVID-19 pandemic onset were noted, compared to what was expected. This may be explained by a number of factors, including cultural values, recipients living in the home with their caregivers, a lack of change in employment status, or imprecision in self-reports from caregivers
