Challenges and opportunities in rapid disaster research: lessons from the field in New Mexico and Vanuatu.

Rapid research is essential to assess impacts in communities affected by disasters, particularly those communities made "hard-to-reach" due to their active marginalization across history and in contemporary practices. In this article, we describe two rapid research projects developed to assess needs for and experiences of communities hard-hit by disasters. The first is a project on the COVID-19 pandemic in southern New Mexico (USA) that was developed to provide information to local agencies that are deploying programs to rebuild and revitalize marginalized communities.

Maternal stress and hair cortisol among pregnant women following hurricane Florence.

Unlabelled: Natural disasters represent major stressors, resulting in psychological distress and physiological responses such as increased cortisol. During pregnancy, this impacts not only maternal well-being, but also fetal development. In 2018, Hurricane Florence caused extensive damage across the eastern United States.

"Go with the Flo": Conducting rapid research on prenatal stress following Hurricane Florence as participant observers.

In this article, we explore the challenges of conceptualizing, designing, and establishing a rapid research agenda as a local researcher following a disaster. We share what we learned while developing and implementing this rapid study and explore the challenges shaped by time pressures, our local context, and resource availability. We identify four core challenges, experienced conducting rapid research, and provide suggestions to overcome these challenges.

Patterns of distress and psychosocial support 2 years post-displacement following a natural disaster in a lower middle income country.

Background: Displacement due to natural disaster exposure is a major source of distress, and disproportionately affects people in low- and middle-income countries (LMICs). Public mental health resources following natural disasters and displacement are often limited in LMICs. In 2017, the population of one island in Vanuatu, a lower-middle income country, was displaced due to volcanic activity.

Relationships of Tobacco Use and Kava Consumption to Sex-Associated Variation in Body Composition and Obesity Risk in Melanesian Adults From Vanuatu.

Obesity prevalence has increased in low- and middle-income countries (LMICs) over the past several decades, with generally greater occurrence among adult females compared with males. Gendered variation in health behaviors, such as substance use, may play a role in how differences in obesity, body size, and composition manifest in association with sex. This study examines sex-moderated relationships of tobacco smoking and kava consumption with body composition and obesity among 301 (local self-identification meaning "of Vanuatu") adults.

Relationships between Objectively Measured Sedentary Behavior during Pregnancy and Infant Birthweight.

Background: Although numerous studies have assessed physical activity during pregnancy and relationships with infant outcomes, such as birthweight, few have evaluated sedentary behavior. Our objective was to evaluate sedentary behavior across pregnancy and relationships with infant birthweight in a sociodemographically diverse sample.

Methods: We measured device-assessed sedentary behavior and physical activity over three days at 16-18, 24-26, and 32-34 weeks gestation and infant birthweight from medical records among 71 participants.

Climate Change, Physical Activity and Sport: A Systematic Review.

Background: Climate change impacts are associated with dramatic consequences for human health and threaten physical activity (PA) behaviors.

Objective: The aims of this systematic review were to present the potential bidirectional associations between climate change impacts and PA behaviors in humans and to propose a synthesis of the literature through a conceptual model of climate change and PA.

Methods: Studies published before October 2020 were identified through database searches in PubMed, PsycARTICLES, CINAHL, SPORTDiscus, GreenFILE, GeoRef, Scopus, JSTOR and Transportation Research Information Services.

Relationships between Prenatal Distress and Infant Body Mass Index in the First Year of Life in a Lower-Middle Income Country.

Prenatal stress affects body composition in childhood and later in life. However, few studies assess body composition in infancy. Furthermore, most are in high-income countries and do not consider interactive or curvilinear relationships.

Variations in Relationships Between Perceived Stress and Birth Outcomes by Immigration Status.

Introduction: Past research shows that stress during pregnancy predicts adverse birth outcomes. These patterns might differ based on immigration status. Our objective was to analyze differences in relationships between perceived stress during pregnancy and birth outcomes by immigration status.

Relationships between mental health and diet during pregnancy and birth outcomes in a lower-middle income country: "Healthy mothers, healthy communities" study in Vanuatu.

Unlabelled: Poor maternal mental health during pregnancy is associated with adverse birth outcomes, including lower birthweight and gestational age. However, few studies assess both mental health and diet, which might have interactive effects. Furthermore, most studies are in high-income countries, though patterns might differ in low- and middle-income countries (LMICs).

Physical Activity Among Immigrant Children: A Systematic Review.

Background: The health benefits of physical activity (PA) for children are well documented. However, little is known about PA patterns among immigrant children.

Methods: The authors reviewed research on PA patterns of immigrant children.

Maternal marital status predicts self-reported stress among pregnant women following hurricane Florence.

Objectives: The effects of stress caused by natural disasters may be more pronounced in individuals with preexisting disadvantages. The degree of hardship and psychological distress associated with Hurricane Florence was assessed in 83 pregnant women. This research helps identify unmarried pregnant women as a group particularly at risk of distress following a natural disaster.

Psychosocial Stress, Sedentary Behavior, and Physical Activity during Pregnancy among Canadian Women: Relationships in a Diverse Cohort and a Nationwide Sample.

Background: Past research shows that psychosocial stress and distress predict sedentary behavior and physical activity, but few studies focus on pregnant women. Our objective was to analyze relationships between psychosocial stress and distress with sedentary behavior and physical activity among pregnant women in Canada.

Methods: We analyzed objectively-measured sedentary behavior and physical activity at 16-18, 24-26, and 32-24 weeks pregnancy in a sociodemographically diverse cohort of 70 women in Montreal, Canada.

Relationships between psychological distress and health behaviors among Canadian adults: Differences based on gender, income, education, immigrant status, and ethnicity.

Objective: Psychosocial health predicts physical health outcomes in both clinical samples and the general population. One mechanism is through relationships with health behaviors. Results might differ based on sociodemographic characteristics such as education, income, ethnicity, and immigrant status.

Psychosocial distress among women following a natural disaster in a low- to middle-income country: "healthy mothers, healthy communities" study in Vanuatu.

Natural disasters have major consequences for mental health in low- and middle-income countries. Symptoms are often more pronounced among women. We analyzed patterns and predictors of distress among pregnant and non-pregnant women 3-4 and 15-16 months after a cyclone in Vanuatu, a low- to middle-income country.

Using multiple correspondence analysis to identify behaviour patterns associated with overweight and obesity in Vanuatu adults.

Objective: The present study evaluates the use of multiple correspondence analysis (MCA), a type of exploratory factor analysis designed to reduce the dimensionality of large categorical data sets, in identifying behaviours associated with measures of overweight/obesity in Vanuatu, a rapidly modernizing Pacific Island country.

Design: Starting with seventy-three true/false questions regarding a variety of behaviours, MCA identified twelve most significantly associated with modernization status and transformed the aggregate binary responses of participants to these twelve questions into a linear scale. Using this scale, individuals were separated into three modernization groups (tertiles) among which measures of body fat were compared and OR for overweight/obesity were computed.

Psychosocial support during displacement due to a natural disaster: relationships with distress in a lower-middle income country.

Background: Past studies show relationships between disaster-related displacement and adverse psychosocial health outcomes. The development of psychosocial interventions following displacement is thus increasingly prioritized. However, data from low- and middle-income countries (LMICs) are lacking.

Prenatal stress and child development: A scoping review of research in low- and middle-income countries.

Introduction: Past research has shown relationships between stress during pregnancy, and related psychosocial health measures such as anxiety and depressive symptoms, with infant, child, and adult outcomes. However, most research is from high-income countries. We conducted a scoping review to identify research studies on prenatal stress and outcomes of the pregnancy or offspring in low- and middle-income countries (LMICs), and to synthesize the stress measures and outcomes assessed, the findings observed, and directions for future research.

Coming to grips with economic development: Variation in adult hand grip strength during health transition in Vanuatu.

Objectives: To determine whether (1) maximal handgrip strength (HGS) is associated with inter-island level of economic development in Vanuatu, (2) how associations between island of residence and HGS are mediated by age, sex, body size/composition, and individual sociodeomographic variation, and (3) whether HGS is predictive of hypertension.

Material And Methods: HGS was collected from 833 adult (aged 18 and older) men and women on five islands representing a continuum of economic development in Vanuatu. HGS was measured using a handheld dynamometer.

Relationships between psychosocial distress and diet during pregnancy and infant birthweight in a lower-middle income country: 'healthy mothers, healthy communities' study in Vanuatu.

Background: Maternal stress during pregnancy is associated with birth outcomes, including birthweight. Exposure to natural disasters during pregnancy provides a model to study these relationships. However, few studies assess both stress and diet, which might have interactive effects.

DNA methylation mediates the effect of maternal cognitive appraisal of a disaster in pregnancy on the child's C-peptide secretion in adolescence: Project Ice Storm.

Animal and human studies suggest that prenatal exposure to stress is associated with adverse health outcomes such as type 2 diabetes. Epigenetic modification, such as DNA methylation, is considered one possible underlying mechanism. The 1998 Quebec ice storm provides a unique opportunity to study an independent prenatal stressor on child outcomes.

Perceptions of group exercise courses and instructors among Quebec adults.

Background: Group exercise courses are popular among adults, but dropout rates are high. Studies of relationships between participants' perceptions and their participation might highlight factors to target to improve adherence and re-enrolment.

Methods: We used a mixed-methods approach to analyse perceptions of group exercise courses and instructors among 463 adults.

The impact of maternal flood-related stress and social support on offspring weight in early childhood.

The current study examined the moderating role of social support in the association between prenatal maternal stress (PNMS) and childhood body mass index (BMI) in the context of the Iowa floods of 2008. In addition, the mediating role of offspring birthweight was examined in the association between PNMS and childhood BMI. We recruited women from eastern Iowa who were pregnant in 2008 when disastrous floods occurred.

Rolling Tobacco in Banana Leaves, Newspaper, or Copybook Paper Associated With Significant Reduction in Lung Function in Vanuatu.

In addition to the widespread availability of packaged cigarettes, the inhabitants of island nations of the Southwest Pacific frequently smoke commercially available loose tobacco using manufactured rolling papers, as well as locally grown tobacco rolled in manufactured rolling paper or wrapped in leaves, copybook paper, and newspaper. In this study, Vanuatu men who smoked local tobacco rolled in leaves, copybook paper, or newspaper showed significantly lower forced vital capacity (FVC), forced expiratory volume in 1 second (FEV), and FEV/FVC ratios than men who smoked packaged cigarettes, store-bought tobacco rolled in manufactured rolling paper, or who smoked locally grown tobacco rolled in manufactured rolling papers. The addition of toxins from these unusual tobacco-wrapping media produces lung function deficits similar to the pattern noted among tobacco smokers who also inhale smoke from burning biomass.
