Abstract
Epidemiology is often described as “the basic science of public health” (Savitz, Poole & Miller, 1999; Syme & Yen, 2000). This description suggests both a close association with public health practice, and the separation of “pure” scientific knowledge from its application in the messy social world. Although the attainability of absolute objectivity is rarely claimed, epidemiologists are routinely encouraged to “persist in their efforts to substitute evidence for faith in scientific reasoning” (Stolley, 1985, p. 38) and reminded that “public health decision makers gain little from impassioned scholars who go beyond advancing and explaining the science to promoting a specific public health agenda” (Savitz et al., 1999, p. 1160). Epidemiology produces authoritative data that are transformed into evidence which informs public health. Those data are authoritative because epidemiology is regarded as a neutral scientific enterprise. Because its claims are grounded in science, epidemiological knowledge is deemed to have “a special technical status and hence is not contestable in the same way as are say, religion or ethics” (Lock, 1988, p. 6). Despite the veneer of universality afforded by its scientific pedigree, epidemiology is not a static or monolithic discipline. Epidemiological truth claims are embodied in several shifting paradigms that span the life of the discipline. Public health knowledges and practices, competing claims internal and external to epidemiology, and structural conditions (such as current political economies, material technologies, and institutions) provide important contexts in which certain kinds of epidemiological knowledge are more likely to emerge.

Abstract
Purpose
This paper aims to explore empirically the interactions between the coronavirus disease 2019 (COVID-19) pandemic, economic mobility and containment policy to test the effectiveness of mobility restrictions in controlling the spread of the disease.
Design/methodology/approach
This study used weekly regional data for the 17 Philippine regions and estimated the effect of shocks using a panel vector autoregression (VAR) model.
Findings
The authors conclude that COVID-19 deaths and incidence primarily respond to shocks that affect the lethality and transmissibility of the disease, and mobility restrictions and strict quarantine levels do not seem to have any impact on these outcomes. The movement of people during this pandemic period, on the other hand, seems to respond more to economic factors and government restrictions and less to the presence of and the characteristics of the disease.
Originality/value
Since the pandemic is a public bad, community cooperation is a must to address it. Clear government messaging that dispels doubts on the safety of the newly developed vaccines and that encourages public acceptance and trust might be a better nudge compared to a heavy-handed and threatening approach.

Abstract
Purpose
Given the popularity of online health communities (OHCs) and medical question-and-answer (Q&A) services, it is increasingly important to understand what constitutes useful answers and user-adopted standards in healthcare domain. However, few studies provide insights into how health information characteristics, provider characteristics and recipient characteristics jointly influence user information adoption decisions. To fill this research gap, this study examines the combined effects of physicians' certainty tone as information characteristics, seniority as provider characteristics and disease severity as recipient characteristics on patients' health information adoption.
Design/methodology/approach
Drawing on dual-process theory and information adoption model, an extended information adoption model is established in this study to examine the effect of attitude certainty on patients' health information adoption, and the moderating effects of online seniority and offline seniority, as well as patient motivation level—disease severity. Utilizing logit regression models, the authors empirically tested the hypotheses based on 4,224 Q&A records from a popular Chinese OHC.
Findings
The results show that (1) attitude certainty has a significant positive impact on patients' health information adoption, (2) the relationship between attitude certainty and information adoption is negatively moderated by physicians' online seniority, but is positively moderated by offline seniority; (3) there is a negative three-way interaction effect of attitude certainty, online seniority and disease severity on patients' health information adoption.
Originality/value
This study extends the information adoption model to examine the two-way interaction between argument quality and source reliability, as well as the three-way interaction with user motivation level, especially for health information adoption in the healthcare field. These findings also provide direct practical applications for knowledge contributors and OHCs.

Abstract
Purpose
This study aims at exploring the role of perceived disease seriousness in consumers’ preference for generic versus branded drugs, by shedding light on new factors impacting consumer purchase behaviour for pharmaceutical products.
Design/methodology/approach
An exploratory study based on a quantitative analysis has been conducted with a sample of 100 participants who have been presented with two different scenarios: one related to more serious disease (as in cardiological disease) and one related to less serious disease (as in the seasonal flu). This paper considered Italy as a research setting where the recent mandatory prescription of the active ingredient by doctors leaves the final purchase decision in consumers’ hands
Findings
Results show that, although consumers are free to choose whether to buy a branded or a generic prescribed active ingredient, their choice is mainly driven by the role of the brand. Consumers’ intention to buy generic drugs is higher in the case of diseases perceived as less serious, while the intention to buy branded drugs is higher in the case of disease perceived as more serious.
Originality/value
This study contributes to marketing research and practice by proposing that consumers’ perceived seriousness of their disease should be considered as a further factor in identifying new marketing strategies in those contexts in which the choice between branded or generic drugs is free.

Abstract
The earliest law of the adulteration of food imposed divisions among the local authorities of the day in functions and enforcements; most of the urban and rural sanitary authorities possessed no power under the law. Provisions dealing with unfit food — diseased, unsound, unwholesome or unfit for human food — were not in the first sale of food and drugs measure and there duties were wholly discharged by all local authorities. Rural sanitary authorities were excluded from food and drugs law and boroughs and urban authorities severly restricted. Enforcement in the rural areas was by the county council, although local officers were empowered to take samples of food and submit them for analysis to the public analyst. Power to appoint the public analyst for the area was the main criterion of a “food and drugs authority”. The Minister had power to direct an authority with a population of less than 40,000 but more than 20,000 to enforce the law of adulteration.

Abstract
Purpose
Dietary fiber and energy intakes seem to be related to disability and anthropometric indices in multiple sclerosis (MS), a chronic inflammatory disorder of the central nervous system. So, this study was designed to investigate the association between dietary fiber and energy intakes with systemic inflammation, disease severity and anthropometric measurements in MS subjects.
Design/methodology/approach
Four subtypes of 261 MS volunteers were recruited (female = 210, male = 51; mean age 38.9 ± 8.3). A 168-item food frequency questionnaire and nutritionist IV software were used to estimate the amounts of dietary, insoluble, soluble, crude fiber and energy intakes. Serum hs-CRP, extended disability status scale (EDSS), height, weight and Deurenberg equation were also used to evaluate systemic inflammation, disease severity, body mass index (BMI) and percentage body fat, respectively.
Findings
Mean differences among the three hs-CRP and EDSS subgroups for dietary fibers and energy intake were significant (p < 0.001). Dietary fiber intake (M = 19.9 ± 4.3 g/day) was a good predictor for EDSS (B = −0.196, p = 0.012), and insoluble fiber intake was introduced as the best predictor of hs-CRP (B = −3.293, p < 0.001). Energy intake predicted both BMI (B = 0.007, p < 0.001) and percentage body fat (B = 0.015, p < 0.001).
Originality/value
Hypocaloric and high prebiotic fiber diet may suppress systemic inflammation and thereby modulate disease severity, as well as control anthropometric indices.

Abstract
In this chapter, the problem of facial palsy has been addressed. Facial palsy is a term used for disruption of facial muscles and could result in temporary or permanent damage of the facial nerve. Patients suffering from facial palsy have issues in doing normal day-to-day activities like eating, drinking, talking, and face psychosocial distress because of their physical appearance. To diagnose and treat facial palsy, the first step is to determine the level of facial paralysis that has affected the patient. This is the most important and challenging step. The research done here proposes how quantitative technology can be used to automate the process of diagnosing the degree of facial paralysis in a fast and efficient way.

Abstract
Purpose
One limitation of research that assesses the effectiveness of physical activity interventions for people with dementia is that most do not describe the intervention in sufficient detail to ascertain a theoretical basis or mechanism of action that determines the effective components. This paper aims to identify studies which evaluate the mechanisms of action of physical activity interventions for people with dementia, to further inform effective intervention development.
Design/methodology/approach
Papers were screened for evidence of evaluation of specific forms of physical activity, using pre-defined inclusion criteria. Analysis was conducted to ascertain if mechanisms of action were corroborated by data within and between studies.
Findings
The authors identified 26 studies with a measured mechanism of action; these related to the effects of physical activity on either neurological structure or endocrinal markers, including hormones. Physical activity had potential to reduce hippocampal atrophy, increase neural recruitment, activate the noradrenergic system and improve anti-inflammatory responses. While individual studies were hampered by small sample sizes, the body of evidence indicated that physical activity may have potential to delay cognitive decline.
Practical implications
Mechanisms of action in relation to dementia and physical activity are likely to be multifaceted, and physical activity may be protective against progression in the early stages of cognitive decline. Physical activity may be of greatest benefit if incorporated into on-going lifestyle, rather than engaged in for short periods, and combined with social interaction.
Originality/value
This paper is unique in its focus on the mechanisms of action of physical activity interventions for people with dementia.

Abstract
Purpose
Epidemics and pandemics can result in sudden morbidity and mortality as well as social and economic disruption. However, the humanitarian logistics and supply chain management (HLSCM) field has been mostly focusing on life saving operations after natural disasters such as earthquakes and hurricanes. There is no research within the HLSCM literature neither on the unique properties of vulnerable groups, nor their underlying risk factors or how to mitigate them. The COVID-19 pandemic highlighted the uniqueness of some vulnerable groups and motivated us to conduct a structured literature review to identify research needs in HLSCM with regards to vulnerable populations.
Design/methodology/approach
The authors conduct a systematic review of literature on the intersection of epidemics/pandemics, humanitarian operations and vulnerable populations. They utilize the Scopus database to search for peer-reviewed journal articles published in English. Our search results in 366 articles which we reduced to 139 after filtering.
Findings
There is no research within the HLSCM literature on the unique properties of various vulnerable populations. The authors show that HLSCM scholars can contribute to literature by investigating operational and logistical challenges of serving vulnerable populations through multi-disciplinary research, research on the intersection of public health and supply chain management, research on the intersection of ethics and operations management, and research on cross-sectoral partnerships.
Research limitations/implications
The authors’ work is limited to peer-reviewed journal articles published in English. They did not include books, conference proceedings and think-tank or NGO reports. However, the authors do recognize that these sources can be very valuable.
Originality/value
To best of authors’ knowledge, this is the first study to review the literature on vulnerable populations under the threat of epidemics and pandemics.

Abstract
Purpose
The purpose of this paper is to examine whether high-cost-sharing ambulatory care policies affect non-urgent emergency department (ED) care utilization differently among individuals with and without chronic conditions.
Design/methodology/approach
This retrospective cohort study used 2010–2011 US Medical Expenditure Panel Survey data. Difference-in-difference methods, multivariate logit model and survey procedures were employed. Time lag effect was used to address endogeneity concerns.
Findings
The sample included 4,347 individuals. Difference in non-urgent ED visits log odds between high- and low-cost-sharing policies was not significantly different between chronically ill and non-chronically ill individuals (β=−0.48, p=0.42). Sensitivity analysis with 15 and 25 percent cost-sharing levels also generated consistent insignificant results (p=0.33 and p=0.31, respectively). Ambulatory care incidence rates were not significantly different between high- and low-cost-sharing groups among chronically ill people (incidence rate ratio=0.849, p=0.069).
Practical implications
High-cost-sharing ambulatory care policies were not associated with increased non-urgent ED care utilization among chronically ill and healthy people. The chronically ill patients may have retained sizable ambulatory care that was necessary to maintain their health. Health plans or employers may consider low-level cost-sharing policies for ambulatory care among chronically ill enrollees or employees.
Originality/value
Findings contribute to insurance benefit design; i.e., whether high-cost-sharing ambulatory care policies should be implemented among chronically ill enrollees to maintain their health and save costs for health plans.
