Neighborhood Socioeconomic Status and Women's Mental Health: A Longitudinal Study of Hurricane Katrina Survivors, 2005-2015.

There is limited knowledge on the relationship between neighborhood factors and mental health among displaced disaster survivors, particularly among women. Hurricane Katrina (Katrina) was the largest internal displacement in the United States (U.S.), which presented itself as a natural experiment. We examined the association between neighborhood socioeconomic status (SES) and mental health among women up to 10 years following Katrina (N = 394). We also investigated whether this association was modified by move status, comparing women who were permanently displaced to those who had returned to their pre-Katrina residence. We used hierarchical linear models to measure this association, using data from the American Community Survey and the Gulf Coast Child and Family Health study. Neighborhood SES was created as an index which represented social and economic characteristics of participants' neighborhoods. Mental health was measured using mental component summary (MCS) scores. Increased neighborhood SES was positively associated with mental health after controlling for age, race/ethnicity, economic positioning, time, and move status (19.6, 95% Confidence Interval: 5.8, 33.7). Neighborhood SES and mental health was also modified by move status. These findings underscore the need to better understand the impacts of socioeconomic conditions and health outcomes among women affected by natural disasters.

Examining the effects of cumulative environmental stressors on Gulf Coast child and adolescent health.

This study examines how community-level cumulative environmental stress affects child and adolescent emotional distress and chronic health conditions both directly and indirectly through stressors at the household, family, and individual levels. Data comes from the Women and their Children's Health (WaTCH) Study, which sought to understand the health implications of exposure to the 2010 Deepwater Horizon oil spill (DHOS) among a cohort of 596 mothers with children ages 10 to 17 in southeastern Louisiana. Community-level environmental stress was measured using a newly developed geospatial index. Household-level stressors included previous hurricane impacts, impacts of DHOS, degree of financial difficulty, and degree of housing physical decay. Family stressors included maternal depression, self-rated physical health, and degree of parenting stress. Child stress was based on perceived stress; child mental health was based on serious emotional disturbance; and child physical health was based on diagnosis of chronic illness. Structural equation modeling used weighted least squares means and variance and theta parameterization. Results showed a significant negative direct path between community-level cumulative environmental stress and child/adolescent serious emotional disturbance and chronic illness. However, the indirect relationship through household, family, and individual-level stressors was significant and positive for both child/adolescent serious emotional disturbance and chronic illness. These findings point to the centrality of the household and family in determining child and adolescent physical and mental health outcomes in communities exposed to frequent disasters and ongoing environmental stressors.

Determinants of the COVID-19 vaccine hesitancy spectrum.

Vaccine hesitancy remains an issue in the United States. This study conducted an online survey [N = 3,013] using the Social Science Research Solution [SSRS] Opinion Panel web panelists, representative of U.S. adults age 18 and older who use the internet, with an oversample of rural-dwelling and minority populations between April 8 and April 22, 2021- as vaccine eligibility opened to the country. We examined the relationship between COVID-19 exposure and socio-demographics with vaccine intentions [eager-to-take, wait-and-see, undecided, refuse] among the unvaccinated using multinomial logistic regressions [ref: fully/partially vaccinated]. Results showed vaccine intentions varied by demographic characteristics and COVID-19 experience during the period that eligibility for the vaccine was extended to all adults. At the time of the survey approximately 40% of respondents were unvaccinated; 41% knew someone who had died of COVID-19, and 38% had experienced financial hardship as a result of the pandemic. The vaccinated were more likely to be highly educated, older adults, consistent with the United States initial eligibility criteria. Political affiliation and financial hardship experienced during the pandemic were the two most salient factors associated with being undecided or unwilling to take the vaccine.

Occupational Conditions Associated With Negative Mental Health Outcomes in New York State Health Professionals During the COVID-19 Pandemic.

OBJECTIVE: The aim of this study was to assess occupational circumstances associated with adverse mental health among health care workers during the COVID-19 pandemic. METHODS: A cross-sectional study examined responses to an on-line survey conducted among 2076 licensed health care workers during the first pandemic peak. Mental health (depression, anxiety, stress, and anger) was examined as a multivariate outcome for association with COVID-related occupational experiences. RESULTS: Odds of negative mental health were increased among those who worked directly with patients while sick themselves (adjusted odds ratio, 2.29; 95% confidence interval, 1.71-3.08) and were independently associated with working more hours than usual in the past 2 weeks, having family/friends who died due to COVID-19, having COVID-19 symptoms, and facing insufficiencies in personal protective equipment/other shortages. CONCLUSIONS: Occupational circumstances were associated with adverse mental health outcomes among health care workers during the COVID-19 pandemic, and some are potentially modifiable.

Differences in post-disaster mental health among Vietnamese and African Americans living in adjacent urban communities flooded by Katrina.

Some communities recover more quickly after a disaster than others. Some differentials in recovery are explained by variation in the level of disaster-related community damage and differences in pre-disaster community characteristics, e.g., the quality of housing stock. But distinct communities that are similar on the above characteristics may experience different recovery trajectories, and, if so, these different trajectories must be due to more subtle differences among them. Our principal objective is to assess short-term and long-term post-disaster mental health for Vietnamese and African Americans living in two adjacent communities in eastern New Orleans that were similarly flooded by Hurricane Katrina. We employ data from two population-based cohort studies that include a sample of African American adults (the Gulf Coast Child and Family Health [GCAFH study]) and a sample of Vietnamese American adults (Katrina Impacts on Vietnamese Americans [KATIVA NOLA study]) living in adjacent neighborhoods in eastern New Orleans who were assessed near the second and thirteenth anniversaries of the disaster. Using the 12-Item Short Form Survey (SF-12) as the basis of our outcome measure, we find in multivariate analysis a significant advantage in post-disaster mental health for Vietnamese Americans over their African American counterparts at the two-year mark, but that this advantage had disappeared by the thirteenth anniversary of the Katrina disaster.

The Formation of Belief: An Examination of Factors That Influence Climate Change Belief Among Hurricane Katrina Survivors.

Differences in population-level climate change beliefs have been identified, which are often attributable to coastline proximity, urban-rural classifications, race, ethnicity, political affiliation, gender, education, socioeconomic status, and age. This study assessed the impact of spatial, experiential, and demographic-related characteristics on climate change beliefs among a population of Hurricane Katrina survivors. Participants from the Gulf Coast Child and Family Health Study who answered climate change belief questions were included in this analysis. Race was found to be the most critical contributor to climate change belief, where the adjusted odds of white individuals believing in climate change were 0.2 times the odds of Black individuals believing in climate change (confidence interval: 0.1-0.4). Other sociodemographic factors, such as age, gender, income, and education, were not found to be significant. Several theoretical perspectives were considered to explain the variation in climate change beliefs, including social vulnerability, environmental deprivation, and political ideology. Future research as to why these racial differences exist should be conducted. By doing so, climate change communication, education, and mitigation and adaptation strategies may be improved.

Bowling Together: Community Social Institutions Protective Against Poor Child Mental Health.

Social capital is widely recognized as health bolstering and more recently as playing a central role in family and community disaster response and recovery. Community social institutions may be considered a critical mechanism for the development of social capital, as they provide opportunities for community members to interact to build the networks and relationships that are necessary for taking collective action. In particular, social institutions may have a pivotal role to play in supporting children's health and welfare postdisaster. Community social institutions such as membership, civic, and religious organizations are community resources that stimulate learning and foster healthy child development. This study explores communities impacted by Hurricane Katrina and the Deepwater Horizon Oil Spill (DWHOS). Social institutions data were paired with household interviews from the Women and Their Children's Health Study (n = 521) to explore whether the density and type of community social institutions in the community were associated with child mental health outcomes. Multilevel logistic regression models examining the role of social institutions, household characteristics, maternal characteristics, and child-specific factors in child mental health showed that for each additional prosocial institution established in the community during recovery from Hurricane Katrina, respondents were 21% less likely to report a child mental health diagnosis (odds ratio 0.79; 95% confidence interval 0.63-0.98). These findings highlight the potential of investment in social institutions in communities to bolster resilience and foster meaningful recovery.

Rapid Behavioral Health Assessment Post-disaster: Developing and Validating a Brief, Structured Module.

To develop and validate a brief, structured, behavioral health module for use by local public health practitioners to rapidly assess behavioral health needs in disaster settings. Data were collected through in-person, telephone, and web-based interviews of 101 individuals affected by Hurricanes Katrina (n = 44) and Sandy (n = 57) in New Orleans and New Jersey in April and May 2018, respectively. Questions included in the core module were selected based on convergent validity, internal consistency reliability, test-retest reliability across administration modes, principal component analysis (PCA), question comprehension, efficiency, accessibility, and use in population-based surveys. Almost all scales showed excellent internal consistency reliability (Cronbach's alpha, 0.79-0.92), convergent validity (r > 0.61), and test-retest reliability (in-person vs. telephone, intra-class coefficient, ICC, 0.75-1.00; in-person vs. web-based ICC, 0.73-0.97). PCA of the behavioral health scales yielded two components to include in the module-mental health and substance use. The core module has 26 questions-including self-reported general health (1 question); symptoms of posttraumatic stress disorder, depression, and anxiety (Primary Care PTSD Screen, Patient Health Questionnaire-4; 8 questions); drinking and other substance use (Alcohol Use Disorders Identification Test-Concise, AUDIT-C; Drug Abuse Screening Test, DAST-10; stand-alone question regarding increased substance use since disaster; 14 questions); prior mental health conditions, treatment, and treatment disruption (3 questions)-and can be administered in 5-10 minutes through any mode. This flexible module allows practitioners to quickly evaluate behavioral health needs, effectively allocate resources, and appropriately target interventions to help promote recovery of disaster-affected communities.

Towards integrated modeling of the long-term impacts of oil spills.

Although great progress has been made to advance the scientific understanding of oil spills, tools for integrated assessment modeling of the long-term impacts on ecosystems, socioeconomics and human health are lacking. The objective of this study was to develop a conceptual framework that could be used to answer stakeholder questions about oil spill impacts and to identify knowledge gaps and future integration priorities. The framework was initially separated into four knowledge domains (ocean environment, biological ecosystems, socioeconomics, and human health) whose interactions were explored by gathering stakeholder questions through public engagement, assimilating expert input about existing models, and consolidating information through a system dynamics approach. This synthesis resulted in a causal loop diagram from which the interconnectivity of the system could be visualized. Results of this analysis indicate that the system naturally separates into two tiers, ocean environment and biological ecosystems versus socioeconomics and human health. As a result, ocean environment and ecosystem models could be used to provide input to explore human health and socioeconomic variables in hypothetical scenarios. At decadal-plus time scales, the analysis emphasized that human domains influence the natural domains through changes in oil-spill related laws and regulations. Although data gaps were identified in all four model domains, the socioeconomics and human health domains are the least established. Considerable future work is needed to address research gaps and to create fully coupled quantitative integrative assessment models that can be used in strategic decision-making that will optimize recoveries from future large oil spills.

The effects of cumulative natural disaster exposure on adolescent psychological distress.

Natural disasters are becoming more frequent and destructive due to climate change and have been shown to be associated with a variety of adverse mental health outcomes in children and adolescents. This study utilizes data from three cohort studies of Hurricane Katrina survivors-including low-income mothers from New Orleans; displaced and highly impacted families from Louisiana and Mississippi; and Vietnamese immigrants in New Orleans-to examine the relationship between cumulative natural disaster exposure and adolescent psychological distress approximately 13 years after Katrina. Among 648 respondents with children ages 10-17, 112 (17.2%) reported that their child had exhibited one or more symptoms of psychological distress in the past month. Overall, respondents had experienced an average of 0.6 (SD 1.0) natural disasters following Hurricane Katrina. Each additional natural disaster experienced by the respondent was associated with 1.41 (95% CI 1.05, 1.88) greater odds of his or child experiencing psychological distress in the past month. This relationship was not significantly moderated by any measures of family resilience or vulnerability, nor by race/ethnicity or socioeconomic status, although family functioning, parental coping, and caregiver mental health were independently associated with adolescent psychological distress. The results of this analysis suggest that natural disasters have cumulative, detrimental impacts on adolescent mental health.

Cross-Sectional Psychological and Demographic Associations of Zika Knowledge and Conspiracy Beliefs Before and After Local Zika Transmission.

Perceptions of infectious diseases are important predictors of whether people engage in disease-specific preventive behaviors. Having accurate beliefs about a given infectious disease has been found to be a necessary condition for engaging in appropriate preventive behaviors during an infectious disease outbreak, while endorsing conspiracy beliefs can inhibit preventive behaviors. Despite their seemingly opposing natures, knowledge and conspiracy beliefs may share some of the same psychological motivations, including a relationship with perceived risk and self-efficacy (i.e., control). The 2015-2016 Zika epidemic provided an opportunity to explore this. The current research provides some exploratory tests of this topic derived from two studies with similar measures, but different primary outcomes: one study that included knowledge of Zika as a key outcome and one that included conspiracy beliefs about Zika as a key outcome. Both studies involved cross-sectional data collections that occurred during the same two periods of the Zika outbreak: one data collection prior to the first cases of local Zika transmission in the United States (March-May 2016) and one just after the first cases of local transmission (July-August). Using ordinal logistic and linear regression analyses of data from two time points in both studies, the authors show an increase in relationship strength between greater perceived risk and self-efficacy with both increased knowledge and increased conspiracy beliefs after local Zika transmission in the United States. Although these results highlight that similar psychological motivations may lead to Zika knowledge and conspiracy beliefs, there was a divergence in demographic association.

Housing Transitions and Recovery of Older Adults Following Hurricane Sandy.

OBJECTIVES: This study explores the effects of social and environmental disruption on emergency housing transitions among older adults following Hurricane Sandy. It is based upon the Sandy Child and Family Health (S-CAFH) Study, an observational cohort of 1,000 randomly sampled New Jersey residents living in the nine counties most affected by Sandy. METHODS: This analysis examines the post-Sandy housing transitions and recovery of the young-old (55-64), mid-old (65-74), and old-old (75+) compared with younger adults (19-54). We consider length of displacement, number of places stayed after Sandy, the housing host (i.e., family only, friends only, or multi-host), and self-reported recovery. RESULTS: Among all age groups, the old-old (75+) reported the highest rates of housing damage and were more likely to stay in one place besides their home, as well as stay with family rather than by themselves after the storm. Despite this disruption, the old-old were most likely to have recovered from Hurricane Sandy. DISCUSSION: Findings suggest that the old-old were more resilient to Hurricane Sandy than younger age groups. Understanding the unique post-disaster housing needs of older adults can help identify critical points of intervention for their post-disaster recovery.

Support for vector control strategies in the United States during the Zika outbreak in 2016: The role of risk perception, knowledge, and confidence in government.

Limiting the spread and impact of Zika was a major global priority in 2016, which required a variety of vector control measures. The success of vector control campaigns is varied and often dependent on public or political will. This paper examines the change over time in the United States population's support for vector control and the factors that predicted support for three vector control strategies (i.e., indoor spraying, outdoor spraying, and use of larvacide tablets) during the 2016 Zika outbreak in the United States. Data is from a nationally representative random digit dial sample conducted at three time points in 2016. Bivariate and multivariate regression analyses were used, treating data as a pooled cross-sectional sample. Results show public support for vector control strategies depends on both perceived risk for disease and knowledge of disease characteristics, as well is confidence in government to prevent the threat. Support varied based on vector control method: indoor spraying, aerial spraying, and use of larvacide tables. Results can aide public health officials in implementing effective vector control campaigns depending on the vector control strategy of choice. Results have implications for ways to design effective prevention campaigns in future emerging infectious disease threats.

Factors Associated with Continued Food Insecurity among Households Recovering from Hurricane Katrina.

In 2010, 14.5% of US households experienced food insecurity, which adversely impacts health. Some groups are at increased risk for food insecurity, such as female-headed households, and those same groups are often also at increased risk for disaster exposure and the negative consequences that come with exposure. Little research has been done on food insecurity post-disaster. The present study investigates long-term food insecurity among households heavily impacted by Hurricane Katrina. A sample of 683 households participating in the Gulf Coast Child and Family Health Study were examined using a generalized estimation model to determine protective and risk factors for food insecurity during long-term recovery. Higher income (Odds Ratio (OR) 0.84, 95% Confidence Interval (CI) 0.77, 0.91), having a partner (OR 0.93; 95% CI 0.89, 0.97), or "other" race were found to be protective against food insecurity over a five-year period following disaster exposure. Low social support (OR 1.14; 95% CI 1.08, 1.20), poor physical health (OR 1.08; 95% CI 1.03, 1.13) or mental health (OR 1.13; 95% CI 1.09, 1.18), and female sex (OR 1.05; 95% CI 1.01, 1.10) were risk factors. Policies and programs that increase access to food supplies among high-risk groups are needed to reduce the negative health impacts of disasters.

Variations in Healthcare Provider Use of Public Health and Other Information Sources by Provider Type and Practice Setting During New York City's Response to the Emerging Threat of Zika Virus Disease, 2016.

The New York City (NYC) Department of Health and Mental Hygiene (DOHMH) used multiple methods to provide guidance to healthcare providers on the management and prevention of Zika virus disease during 2016. To better understand providers' use of information sources related to emerging disease threats, this article describes reported use of information sources by NYC providers to stay informed about Zika, and patterns observed by provider type and practice setting. We sent an electronic survey to all email addresses in the Provider Data Warehouse, a system used to maintain information from state and local health department sources on all prescribing healthcare providers in NYC. The survey asked providers about their use of information sources, including specific information products offered by the NYC DOHMH, to stay informed about Zika during 2016. Trends by provider type and practice setting were described using summary statistics. The survey was sent to 44,455 unique email addresses; nearly 20% (8,711) of the emails were undeliverable. Ultimately, 1,447 (5.8%) eligible providers completed the survey. Most respondents (79%) were physicians. Overall, the most frequently reported source of information from the NYC DOHMH was the NYC Health Alert Network (73%). Providers in private practice reported that they did not use any NYC DOHMH source of information about Zika more frequently than did those working in hospital settings (29% vs 23%); similarly, private practitioners reported that they did not use any other source of information about Zika more frequently than did those working in hospital settings (16% vs 8%). Maintaining timely and accurate databases of healthcare provider contact information is a challenge for local public health agencies. Effective strategies are needed to identify and engage independently practicing healthcare providers to improve communications with all healthcare providers during public health emergencies.

How the US Population Engaged with and Prioritized Sources of Information about the Emerging Zika Virus in 2016.

Emerging disease threats like Zika pose a risk to naïve populations. In comparison to chronic diseases, there is scientific uncertainty surrounding emerging diseases because of the lack of medical and public health information available as the threat emerges. Further complicating this are the multiple, diverse channels through which people get information. This article used bivariate and multivariate analysis to first describe the breadth of information sources individuals accessed about the Zika virus, and then describe individuals' primary sources of information for Zika using a nationally representative pooled cross-sectional data set collected at 3 time points in 2016 (N = 3,698). The analysis also highlights how 3 subgroups-high-education, high-income adults; Hispanic women of childbearing age; and retirees over the age of 65 with less than a high school education-varied in their use of information. Results suggest individuals accessed multiple sources, but TV and radio were the primary sources of Zika information for the public, followed by print news. Demographic variation in primary source of information means public health officials should consider alternative channels to reach target groups in an emerging event. Without an understanding of how information has reached people, and who individuals engaged with regarding that information, public health practitioners are missing a key piece of the puzzle to improving public health campaigns during a future event like Zika. This analysis aims to inform the public health community about the message channels the US population uses during an emerging disease event and the most prevalent channels for different demographic groups, who can be targeted with particular messaging.

Application of a Theoretical Model Toward Understanding Continued Food Insecurity Post Hurricane Katrina.

OBJECTIVE: Disaster recovery efforts focus on restoring basic needs to survivors, such as food, water, and shelter. However, long after the immediate recovery phase is over, some individuals will continue to experience unmet needs. Ongoing food insecurity has been identified as a post-disaster problem. There is a paucity of information regarding the factors that might place an individual at risk for continued food insecurity post disaster. METHODS: Using data from a sample (n=737) of households severely impacted by Hurricane Katrina, we estimated the associations between food insecurity and structural, physical and mental health, and psychosocial factors 5 years after Hurricane Katrina. Logistic regression models were fit and odds ratios (OR) and 95% CI estimated. RESULTS: Nearly one-quarter of respondents (23%) reported food insecurity 5 years post Katrina. Marital/partner status (OR: 0.7, CI: 0.42, 0.99), self-efficacy (OR: 0.56, CI: 0.37, 0.84), sense of community (OR: 0.7, CI: 0.44, 0.98), and social support (OR: 0.59, CI: 0.39, 0.89) lowered the odds of food insecurity and explained most of the effects of mental health distress on food insecurity. Social support, self-efficacy, and being partnered were protective against food insecurity. CONCLUSIONS: Recovery efforts should focus on fostering social-support networks and increased self-efficacy to improve food insecurity post disaster. (Disaster Med Public Health Preparedness. 2018;12:47-56).

Risk salience of a novel virus: US population risk perception, knowledge, and receptivity to public health interventions regarding the Zika virus prior to local transmission.

BACKGROUND: As the incidence of Zika infection accelerated in Central and South American countries from November 2015 through April 2016, U.S. public health officials developed vector control and risk communication strategies to address mosquito-borne and sexual modes of transmission. This study reports upon U.S. perceptions of the Zika virus prior to domestic transmission, and analyzes the association of socio-economic, political, knowledge and risk factors with population receptivity to selected behavioral, environmental, and clinical intervention strategies. METHODS: A representative sample of 1,233 U.S. residents was drawn from address-based telephone and mobile phone lists, including an oversample of 208 women of child-bearing age living in five U.S. southern states. Data were collected between April and June, 2016, and weighted to represent U.S. population distributions. RESULTS: Overall, 78% of the U.S. population was aware of Zika prior to domestic transmission. Those unaware of the novel virus were more likely to be younger, lower income, and of Hispanic ethnicity. Among those aware of Zika, over half would delay pregnancy for a year or more in response to public health warnings; approximately one third agreed with a possible vector-control strategy of targeted indoor spraying by the government; and nearly two-thirds agreed that the government should make pregnancy-termination services available to women who learn their fetus had a Zika-related birth defect. Receptivity to these public health interventions varied by age, risk perception, and knowledge of the virus. CONCLUSION: Risk salience and population receptivity to public health interventions targeting a novel virus can be conditioned on pre-existing characteristics in the event of an emerging infectious disease. Risk communicators should consider targeted strategies to encourage adoption of behavioral, environmental, and clinical interventions.

The Women and Their Children's Health (WaTCH) study: methods and design of a prospective cohort study in Louisiana to examine the health effects from the BP oil spill.

PURPOSE: The Deepwater Horizon Oil Spill is the largest marine oil spill in US history. Few studies have evaluated the potential health effects of this spill on the Gulf Coast community. The Women and Their Children's Health (WaTCH) study is a prospective cohort designed to investigate the midterm to long-term physical, mental and behavioural health effects of exposure to the oil spill. PARTICIPANTS: Women were recruited by telephone from pre-existing lists of individuals and households using an address-based sampling frame between 2012 and 2014. Baseline interviews obtained information on oil spill exposure, demographics, physical and mental health, and health behaviours. Women were also asked to provide a household roster, from which a child between 10 and 17 years was randomly selected and recruited into a child substudy. Telephone respondents were invited to participate in a home visit in which blood samples, anthropometrics and neighbourhood characteristics were measured. A follow-up interview was completed between 2014 and 2016. FINDINGS TO DATE: 2852 women completed the baseline interview, 1231 of whom participated in the home visit, and 628 children participated in the child's health substudy. The follow-up interview successfully reinterviewed 2030 women and 454 children. FUTURE PLANS: WaTCH continues to conduct follow-up surveys, with a third wave of interviews planned in 2017. Also, we are looking to enhance the collection of spatially related environmental data to facilitate assessment of health risks in the study population. In addition, opportunities to participate in behavioural interventions for subsets of the cohort have been initiated. There are ongoing studies that examine the relationship between genetic and immunological markers with mental health.
