Despite the profound health and economic implications of Covid-19, there is only limited knowledge to date about the role of economic concerns, health worries and social distancing for mental health ...outcomes during the pandemic. We analyze online survey data from the nationally representative "Understanding America Study" (UAS) covering the period of March 10-31st 2020 (sample size: 6,585). Mental health is assessed by the validated PHQ-4 instrument for measuring symptoms of depression and anxiety. About 29% (CI:27.4-.30.4%) of the US adult population reported some depression/anxiety symptoms over the study period, with symptoms deteriorating over the month of March. Worsening mental health was most strongly associated with concerns about the economic consequences of the pandemic, while concerns about the potential implications of the virus for respondents' own health and social distancing also predicted increases in symptoms of depression and anxiety during the early stages of the pandemic in the US, albeit less strongly. Our findings point towards the possibility of a major mental health crisis unfolding simultaneously with the pandemic, with economic concerns being a key driving force of this crisis. These results highlight the likely importance of economic countermeasures and social policy for mitigating the impact of Covid-19 on adult mental health in the US over and above an effective public health response.
As COVID-19 is rapidly unfolding in the United States, it is important to understand how individuals perceive the health and economic risks of the pandemic. In the absence of a readily available ...medical treatment, any strategy to contain the virus in the US will depend on the behavioral response of US residents. In this paper, we study individual's perceptions on COVID-19 and social distancing during the week of March 10-16, 2020, a week when COVID-19 was officially declared to be a pandemic by WHO and when new infections in the US were more than doubling every three days. Using a nationally representative sample of 5,414 respondents 18+ years of age from the Understanding America Study (UAS), we find that perceptions about COVID-19 health risks and economic consequences in the US population were largely pessimistic and highly variable by age and education. US residents who are young and do not have a college degree perceived a lower risk of getting infected but a higher probability of running out of money than others. Most individuals reported taking some steps to distance themselves from others but important differences emerge by gender and by source of information on COVID-19. Using state and day fixed-effect regressions, we show that perceptions of the health risks closely followed the number of COVID-19 cases in the country, and perceptions of the economic consequences and the prevalence of social distancing were driven upwards by both national and state-level cases. Unless addressed by effective health communication that reaches individuals across all social strata, variations in perceptions about COVID-19 epidemic raise concerns about the ability of the US to implement and sustain the widespread and restrictive policies that are required to curtail the pandemic.
Abstract
Objectives
We assess how age, the presence of mature adults aged 45+ years, and recent deaths in rural households are associated with coronavirus disease 2019 (COVID-19) preventative actions ...and the likelihood of getting vaccinated against the virus in Malawi during early stages of the pandemic.
Methods
We draw upon data from 2,187 rural Malawians who participated in a 2020 COVID-19 Phone Survey. We estimate the log odds of engaging in “low-cost” and “high-cost” COVID-19 preventative actions based on age, gender, household composition, and recent household deaths. Low-cost prevention efforts were washing hands with soap and water frequently, avoiding close contact with people when going out, and avoiding shaking hands. High-cost actions included staying at home and decreasing time spent close to people not living in their household. We also estimate the chances of acquiring the COVID-19 vaccine in early stages of its availability.
Results
Mature women (45+ years) in general and younger men (<45 years)—living with at least one mature adult in the household—were less likely than others to comply with low-cost actions. Mature men were more likely than younger men (<45 years) to take on high-cost actions. To some extent, individuals who experienced a recent family death were more likely to engage in high-cost COVID-19 preventative actions as well as getting vaccinated.
Discussion
Gendered age differences in preventing the transmission of COVID-19 offer hints of larger social norms affecting protective efforts. The analyses also inform future COVID-19 public health outreach efforts in Malawi and other rural SSA contexts.
In a context where pessimistic survival perceptions have been widespread as a result of the HIV/AIDS epidemic ( Fig. 1 A ), we study vaccine uptake and other health behaviors during the recent ...COVID-19 pandemic. Leveraging a longitudinal cohort study in rural Malawi that has been followed for up to 25 y, we document that a 2017 mortality risk information intervention designed to reduce pessimistic mortality perceptions ( Fig. 1 B ) resulted in improved health behavior, including COVID-19 vaccine uptake ( Fig. 1 C ). We also report indirect effects for siblings and household members. This was likely the result of a reinforcing process where the intervention triggered engagement with the healthcare system and stronger beliefs in the efficacy of modern biomedical treatments, which led to the adoption of health risk reduction behavior, including vaccine uptake. Our findings suggest that health information interventions focused on survival perceptions can be useful in promoting health behavior and participation in the formal healthcare system, even during health crises—such as the COVID-19 pandemic—that are unanticipated at the time of the intervention. We also note the importance of the intervention design, where establishing rapport, tailoring the content to the local context, and spending time with respondents to convey the information contributed to the salience of the message.
An influential literature on the Developmental Origins of Health and Disease (DOHaD) has documented that poor conditions
lead to higher risk of cardiovascular disease at older ages. Evidence from ...low-income countries (LICs) has hitherto been missing, despite the fact that adverse
conditions are far more common in LICs. We find that Malawians exposed
to the 1949 Nyasaland famine have
cardiovascular health 70 years later. These findings highlight the potential context specificity of the DOHaD hypothesis, with
adversity having different health implications among aging LIC individuals who were exposed to persistent poverty.
•Malawi, a low-income sub-Saharan African country, had a relatively successful early response to the Covid-19 pandemic.•Activities of community leaders (village heads, VHs) were possibly critical for ...behavioral and economic responses that helped contain Covid-19.•Communities with active VHs were more likely to follow social distancing and take steps to limit the economic consequences of the Covid-19 pandemic.•Trust in the health care workers and the government during the pandemic are also positively associated with village head activities.•Engaging community leaders should be an important aspect of the Covid-19 response in countries where vaccine roll-out continues to be slow.
Utilizing population-based data from the Covid-19 phone survey (N=2,262) of the Malawi Longitudinal Study of Families and Health (MLSFH) collected during June 2nd–August 17th, 2020, we focus on the crucial role that community leadership and trust in institutions played in shaping behavioral, economic and social responses to Covid-19 in this low-income sub-Saharan African context. We argue that the effective response of Malawi to limit the spread of the virus was facilitated by the engagement of local leadership to mobilize communities to adapt and adhere to Covid-19 prevention strategies. Using linear and ordered probit models and controlling for time fixed effects, we show that village heads (VHs) played pivotal role in shaping individuals’ knowledge about the pandemic and the adoption of preventive health behaviors and were crucial for mitigating the negative economic and health consequences of the pandemic. We further show that trust in institutions is of particular importance in shaping individuals’ behavior during the pandemic, and these findings highlight the pivotal role of community leadership in fostering better compliance and adoption of public health measures essential to contain the virus. Overall, our findings point to distinctive patterns of pandemic response in a low-income sub-Saharan African rural population that emphasized local leadership as mediators of public health messages and policies. These lessons from the first pandemic wave remain relevant as in many low-income countries behavioral responses to Covid-19 will remain the primary prevention strategy for a foreseeable future.
Cognition and its age-related changes remain vastly understudied in low-income countries (LICs), despite evidence suggesting that cognitive decline among aging low-income populations is a rapidly ...increasing disease burden often occurring at younger ages as compared to high-income countries (HICs).
We examine patterns of cognition among men and women, 45 + years old, living in rural Malawi. We analyze how key socioeconomic characteristics predict levels of cognition and its changes as individuals get older.
Utilizing the Mature Adults Cohort of the Malawi Longitudinal Study of Families and Health (MLSFH-MAC) collected during 2012-2017, we estimate standard regression models to analyze predictors of the age- and sex-specific levels and longitudinal changes in cognition. Cognition is assessed with a screening instrument that is adapted to this low-literacy context and measures different domains such as language, attention, or executive functioning.
Women have lower levels of cognition than men, a pattern in stark contrast to findings in HICs. Schooling and socioeconomic status increase the probability of having consistently high performance during the cognitive assessment. Cognitive decline accelerates with age and is detectable already at mid-adult ages (45-55 years). Despite lower levels of cognitive function observed among women, the pace of decline with age is similar for both genders.
Women are particularly affected by poor cognition in this context. The study emphasizes the importance of prioritizing cognitive health and research on cognition among older individuals in sub-Saharan Africa LICs, to which relatively little health care resources continue to be allocated.
There is an increased need for efficient, low-cost methods to collect information on a range of widely prevalent mental health outcomes in the general population that can be administered outside of ...clinical settings. We evaluate the validity of a single-item Visual Analogue Scale (VAS) for assessing the presence and severity of depression and compare its performance with the Patient Health Questionnaire (PHQ-9) depression scale using a large non-clinical sample (N = 1816) of college students from Switzerland. The VAS scale is strongly correlated with the PHQ-9 total score (0.61) and its 9 individual items (ranging from 0.19 to 0.67). ROC analysis shows that the VAS scale has high accuracy for detecting the presence and different levels (mild to severe) of depression corresponding to PHQ-9 cutoffs. The VAS depression scale represents a simple, easily implementable instrument that is suitable for mental health research in common settings and larger population-based studies.
PurposeThe Mature Adults Cohort of the Malawi Longitudinal Study of Families and Health (MLSFH-MAC) contributes to global ageing studies by providing a rare opportunity to study the processes of ...individual and population ageing, the public health and social challenges associated with ageing and the coincident shifts in disease burdens, in a low-income, high HIV prevalence, sub-Saharan African (SSA) context.ParticipantsThe MLSFH-MAC is an open population-based cohort study of mature adults aged 45+ years living in rural communities in three districts in Malawi. Enrolment at baseline is 1266 individuals in 2012. Follow-ups were in 2013, 2017 and 2018 when the cohort size reached 1626 participants in 2018.Findings to dateSurvey instruments cover ageing-related topics such as cognitive and mental health, non-communicable diseases (NCDs) and related health literacy, subjective survival expectations, measured biomarkers including HIV, grip strength, hypertension, fasting glucose, body mass index (BMI), broad individual-level and household-level social and economic information, a 2018 qualitative survey of mature adults and community officials, 2019 surveys of village heads, healthcare facilities and healthcare providers in the MLSFH-MAC study areas. Across many domains, MLSFH-MAC allows for comparative research with global ageing studies through harmonised measures and instruments. Key findings to date include a high prevalence of depression and anxiety among older adults, evidence for rapid declines in cognitive health with age, a low incidence of HIV among mature adults, rising prevalence of HIV due to increased survival of HIV-positive individuals and poor physical health with high NCD prevalence.Future plansAn additional wave of MLSFH-MAC is forthcoming in 2021, and future expansions of the cohort are planned. MLSFH-MAC data will also be publicly released and will provide a wealth of information unprecedented for ageing studies in a low-income SSA context that broadly represents the socioeconomic environment of millions of individuals in south-eastern Africa.
•Evidence lacks on the effectiveness of NCD health screenings in low-income contexts.•We show sustained effects of referrals given to persons with high blood pressure.•Recipients of referral letters ...have a lower blood pressure, and lower probability of being hypertensive by about 22 percentage points four years later.•Key findings agree across regression discontinuity and matching estimators.
Evidence for the effectiveness of population health screenings to reduce the burden of non-communicable diseases in low-income countries remains very limited. We investigate the sustained effects of a health screening in Malawi where individuals received a referral letter if they had elevated blood pressure. Using a regression discontinuity design and a matching estimator, we find that receiving a referral letter reduced blood pressure and the probability of being hypertensive by about 22 percentage points four years later. These lasting effects are explained by a 20 percentage points increase in the probability of being diagnosed with hypertension. There is also evidence of an increase in the uptake of medication, while we do not identify improvements in hypertension-related knowledge or risk behaviors. On the contrary, we find an increase in sugar intake and a decrease in physical activity both of which are considered risky behaviors in Western contexts. The health screening had some positive effects on mental health. Overall, this study suggests that population-based hypertension screening interventions are an effective tool to improve health in low-income contexts.
