Socioeconomic factors differentiating healthcare utilization of cyclone survivors in rural Bangladesh: a case study of cyclone Sidr

Change in cyclone disaster vulnerability and response in coastal Bangladesh

The number of deaths owing to tropical cyclones in Bangladesh has significantly reduced. Category 4 Cyclone Gorky in 1991 and Sidr in 2007 caused 147,000 and 4,500 deaths respectively, whereas Category 1 Cyclone Mora in 2017 resulted in six. Face-to-face interviews with 362 residents, participant observation, and focus-group discussions answer a research question about how change in coastal areas has contributed to this outcome. The study considered institutional approaches of disaster risk management through legal frameworks, administrative arrangements, cyclone preparedness activities, cyclone detection and early warning dissemination, construction of shelter centres, strengthening of various types of coastal embankments, paved roads, and pre-cyclone evacuation. The findings indicate significant improvement in house structures and design, income levels and diversification, education, awareness, individual capacity, poverty reduction, and lowering dependency on agriculture-based earning. Furthermore, the availability of mobile telephones, radio, television, and social media platforms enhanced social connectivity and greater gender equality and empowerment helped to facilitate disaster preparedness, evacuation, and response.

Health Effects of Cyclones: A Systematic Review and Meta-Analysis of Epidemiological Studies

BACKGROUND

More intense cyclones are expected in the future as a result of climate change. A comprehensive review is urgently needed to summarize and update the evidence on the health effects of cyclones.

OBJECTIVES

We aimed to provide a systematic review with meta-analysis of current evidence on the risks of all reported health outcomes related to cyclones and to identify research gaps and make recommendations for further research.

METHODS

We systematically searched five electronic databases (MEDLINE, Embase, PubMed, Scopus, and Web of Science) for relevant studies in English published before 21 December 2022. Following the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines, we developed inclusion criteria, screened the literature, and included epidemiological studies with a quantitative risk assessment of any mortality or morbidity-related outcomes associated with cyclone exposures. We extracted key data and assessed study quality for these studies and applied meta-analyses to quantify the overall effect estimate and the heterogeneity of comparable studies.

RESULTS

In total, 71 studies from eight countries (the United States, China, India, Japan, the Philippines, South Korea, Australia, Brazil), mostly the United States, were included in the review. These studies investigated the all-cause and cause-specific mortality, as well as morbidity related to injury, cardiovascular diseases (CVDs), respiratory diseases, infectious diseases, mental disorders, adverse birth outcomes, cancer, diabetes, and other outcomes (e.g., suicide rates, gender-based violence). Studies mostly included only one high-amplitude cyclone (cyclones with a Saffir-Simpson category of 4 or 5, i.e., Hurricanes Katrina or Sandy) and focused on mental disorders morbidity and all-cause mortality and hospitalizations. Consistently elevated risks of overall mental health morbidity, post-traumatic stress disorder (PTSD), as well as all-cause mortality or hospitalizations, were found to be associated with cyclones. However, the results for other outcomes were generally mixed or limited. A statistically significant overall relative risk of 1.09 [95% confidence interval (CI): 1.04, 1.13], 1.18 (95% CI: 1.12, 1.25), 1.15 (95% CI: 1.13, 1.18), 1.26 (95% CI: 1.05, 1.50) was observed for all-cause mortality, all-cause hospitalizations, respiratory disease, and chronic obstructive pulmonary disease hospitalizations, respectively, after cyclone exposures, whereas no statistically significant risks were identified for diabetes mortality, heart disease mortality, and preterm birth. High between-study heterogeneity was observed.

CONCLUSIONS

There is generally consistent evidence supporting the notion that high-amplitude cyclones could significantly increase risks of mental disorders, especially for PTSD, as well as mortality and hospitalizations, but the evidence for other health outcomes, such as chronic diseases (e.g., CVDs, cancer, diabetes), and adverse birth outcomes remains limited or inconsistent. More studies with rigorous exposure assessment, of larger spatial and temporal scales, and using advanced modeling strategy are warranted in the future, especially for those small cyclone-prone countries or regions with low and middle incomes. https://doi.org/10.1289/EHP12158.

Do health risk perceptions motivate water - and health-related behaviour? A systematic literature review

Health-related risk perceptions are important determinants of health behaviours and components of behaviour change theories. What someone thinks or feels will motivate or hinder their intention or hesitancy to implement a certain behaviour. Thus, a perceived potential risk to our health and well-being can influence our health-promoting and/or health-seeking behaviour. We aimed to review and synthesize available peer-reviewed literature to better understand the links between water and health-related risk perceptions and behaviours. We conducted the first systematic review of peer-reviewed literature on risk perceptions and behaviours in the context of water and health, published between 2000 and 2021. A total of 187 publications met the inclusion criteria. We extracted data relating to study characteristics and categorized our results according to the major themes emerging from the literature, namely drinking water, sanitation, hygiene and wasterelated topics, health risk factors, diseases and mental health implications, and preventative measures. Our review shows that the literature has grown over the past twenty years, reporting information from different countries belonging to different income groups around the globe, conducted in various settings and contexts, among different target populations, from various disciplinary angles, using different methods, theories and approaches. Our review provides evidence of health risk perceptions determining behaviour particularly related to drinking water sources and water safety. Evidence on disease prevention, health seeking, variations and changes in perception and behaviour over space, geography, socioeconomic differences and time, and the relevance of cultural context is provided. Our review shows that risk perception studies are vital for WASH governance in terms of policy, raising awareness, education and behaviour change. In order to make risk perception and behaviour studies even more relevant to effective public health planning and health messaging, future research needs to increasingly focus on early culturally sensitive interventions and changes in perceptions and behaviours over time.

PRIMARY HEALTH CARE ACTIONS IN NATURAL DISASTERS

ABSTRACT Objective: to identify in the national and international literature Primary Health Care actions in natural disasters. Method: an integrative literature review, which included 24 original surveys between 2006 and 2018 on natural disasters. Results: a qualitative analysis of the studies included primary care actions in the prevention and mitigation, preparation, response, and disaster recovery phases. Conclusion: Primary Health Care actions involve multidisciplinary teams, the community and families in the territory in which the teams operate, articulation in a network of intersectoral services, in managerial and educational dimensions to implement effective plans for disaster situations.

Parents' healthcare-seeking behavior for their children among the climate-related displaced population of rural Bangladesh

In Bangladesh climate change has contributed to a massive displacement of people. This study examines the effects of climate-related displacement, socioeconomic status, availability of healthcare providers and disease-related attributes on the healthcare-seeking behaviors of parents for their children. Using cross-sectional survey data from the parents of 1003 children aged under 15 who were ill in the four weeks prior to the interview, collected from 600 randomly-selected households in climate displacement-susceptible areas and 600 households in non-climate-displacement-susceptible areas in Bangladesh, we use multivariate logistic regression to identify the factors associated with parental healthcare-seeking behaviors. The results show that 15.5% of the children who had been ill receive either no care or curative care at home. Of those receiving care outside the home, only 22.1% are treated by trained providers. Climate-related displaced parents are significantly less likely to seek care or to use provider-prescribed care to manage children's illnesses. Areas lacking local healthcare providers, poorer households, females, child age and mild illness are also associated with a child being significantly less likely to be treated outside the home. The children of climate-related displaced parents are around half as likely as those of non-displaced parents to be treated by a trained provider. The local availability of medical doctors, cost of reaching a healthcare center, household income, type and severity of illness, child's age, and joint parental decision-making about care providers are also important predictors of the selection of trained healthcare providers for children. Thus, climate-related displacement affects the healthcare-seeking behaviors of parents for their children. Policy aimed at improving child health should address the socioeconomic disadvantage and access to healthcare of the displaced, the training of local untrained providers about Primary Health Care service provision, and the numbers of medical doctors in the displacement-prone areas.

Lost productivity among military personnel with cardiovascular disease

OBJECTIVE

Cardiovascular disease (CVD) is associated with significant productivity loss among all occupational groups. However, the increased occupational requirements of military personnel pose physical and psychological demands that could lead to greater lost productivity of CVD. The aim of this study was to determine the economic cost of lost productivity of military patients with CVD.

METHODS

A prospective cross-sectional study was undertaken on all military patients attending a specialist CVD clinic in Tehran, Iran. All participants were interviewed using face-to-face questioning using a Valuation of Lost Productivity questionnaire. Data captured included paid and unpaid time lost due to CVD, military job characteristics and their work environment. Ordered logistic regression was used to examine the determinants of lost productivity.

RESULTS

The mean time of lost productivity was 118 hours over a 3-month period, of which 70 and 48 hours were paid and unpaid work, respectively. The average cost per patient of total lost productivity was estimated to be US$303 over a 3-month period.

CONCLUSIONS

CVDs are associated with significant lost productivity among military personnel. There is a statistically significant relation between some military occupation characteristics and lost productivity from CVD. Level of income, teamwork and physical activity have the greatest effects on lost productivity. Military workers who were suffering from other chronic conditions (in addition to CVD) were four times more likely to lose productivity. A supportive work environment should be created for military personnel with emphasis on developing teamwork, improving worker's attitudes towards disease and giving priority to workers with comorbidities.

Factors Affecting Health Care Utilization in Tehran

INTRODUCTION

Successful health system planning and management is dependent on well informed decisions, so having complete knowledge about medical services' utilization is essential for resource allocation and health plans. The main goal of this study is identification of factors effecting inpatient and outpatient services utilization in public and private sectors.

METHODS

This study encompasses all regions of Tehran in 2011 and uses Urban HEART questionnaires. This population-based survey included 34700 households with 118000 individuals in Tehran. For determining the most important factors affected on health services consumption, logit model was applied.

RESULTS

Regarding to the finding, the most important factors affected on utilization were age, income level and deciles, job status, household dimension and insurance coverage. The main point was the negative relationship between health care utilization and education but it had a positive relationship with private health care utilization. Moreover suffering from chronic disease was the most important variable in health care utilization.

CONCLUSIONS

According to the mentioned results and the fact that access has effect on health services utilization, policy makers should try to eliminate financial access barriers of households and individuals. This may be done with identification of households with more than 65 or smaller than 5 years old, people in low income deciles or with chronic illness. According to age effect on health services usage and aging population of Iran, results of this study show more importance of attention to aged population needs in future years.
