How can departments of community medicine shape the future of public health education in India?

In order to effectively respond to a changing public health paradigm, it is imperative that the medical education and overall public health education (PHE) parallel the public health challenges faced by countries. Community medicine departments play a crucial role in PHE. This review analyzes the current situation of community medicine departments in the context of PHE, using a framework that outlines academic activities undertaken by these departments. This framework includes the syllabus of academic programs, internship, and infrastructure and faculty strength in the community medicine departments. The review also discusses how skill building of existing faculty members can help us in addressing emerging public health issues, and the role of partnerships and collaborative activities in advancing the PHE agenda, thereby continuing to shape the role played by these departments toward shaping the future of PHE in India.     

Prediction of the length of service at the onset of coal workers’ pneumoconiosis based on neural network

Abstract

Three environmental parameters, i.e. dust concentrations, dust dispersion, and free silica content, were introduced into the traditional indices of the neural network model in order to construct a new prediction index and explore a new method for preventing the incidence of pneumoconiosis with intelligent accuracy and universality. Data of the pneumoconiosis patients from Huabei Mining Group (HBMG) of China from 1980 to 2017 were collected. SPSS22.0 was used to develop the combined models based on Back Propagation (BP) neural network model, Radial Basis Function (RBF) neural network model, and Multiple Linear Regression (MLR) model. The paired sample t-test was performed between the real and predicted values. According to this model, it was predicted that 382 coal workers in HBMG were likely to suffer from pneumoconiosis in 2022 and the incidence rate was 4.48%. It is necessary to take prevention measures and transfer these workers from their current positions. In four combined models, the BP-MLR combined model achieved the optimal error parameters and the most accurate prediction. This study provided a scientific basis for effective control and prevention of the incidence of the pneumoconiosis.     

The impact of community Men’s Sheds on the physical health of their users

With men more susceptible than women to illness and mortality, and less likely to access primary healthcare services, there have been calls for more male friendly spaces within communities to engage ‘hard to reach’ men in physical health improvement. Research has shown that Men’s Shed (Shed) activity can provide localised support for the mental health and social wellbeing of men within communities, yet less is known about Sheds’ impacts on physical health. Drawing on qualitative interviews with 62 Sheds users, this study conceptualises proposed pathways from which Shed activity can lead to positive physical health outcomes. Findings showed that in attending a community Men’s Shed and taking part in activities users reported (i) increased mobility and decreased sedentary behavior, (ii) increased ability to overcome physical illness or injury, (iii) improved diet, (iv) decreased alcohol use, and (v) improved physical health knowledge. These findings support wider recommendations for community-based male friendly approaches to physical health improvement, and stress the importance of health and care service delivery beyond boundaries of ‘standard’ NHS settings, especially when targeting those viewed as ‘hard to reach’. While initiatives like Sheds do not offer a replacement of primary healthcare services, they have the potential to fit within existing health and social care practices as an alternative local health-engagement space for men.     

Optimising the benefits of community health workers’ unique position between communities and the health sector: A comparative analysis of factors shaping relationships in four countries

Community health workers (CHWs) have a unique position between communities and the health sector. The strength of CHWs’ relationships with both sides influences their motivation and performance. This qualitative comparative study aimed at understanding similarities and differences in how relationships between CHWs, communities and the health sector were shaped in different Sub-Saharan African settings. The study demonstrates a complex interplay of influences on trust and CHWs’ relationships with their communities and actors in the health sector. Mechanisms influencing relationships were feelings of (dis)connectedness, (un)familiarity and serving the same goals, and perceptions of received support, respect, competence, honesty, fairness and recognition. Sometimes, constrained relationships between CHWs and the health sector resulted in weaker relationships between CHWs and communities. The broader context (such as the socio-economic situation) and programme context (related to, for example, task-shifting, volunteering and supervision) in which these mechanisms took place were identified. Policy-makers and programme managers should take into account the broader context and could adjust CHW programmes so that they trigger mechanisms that generate trusting relationships between CHWs, communities and other actors in the health system. This can contribute to enabling CHWs to perform well and responding to the opportunities offered by their unique intermediary position.     

Family, friend or foe? Critical reflections on the relevance and role of social capital in health promotion and community development

Social capital has been the focus of considerable academic and policy interest in recent years. Despite this interest, the concept remains undertheorized: there is an urgent need for a critical engagement with this literature that goes beyond summary. This paper lays a foundation for a critical dialogue between social capital and health promotion, by examining problematics in the conceptualization and practice of social capital building and linking these to models of community development, a cornerstone health promotion strategy. In so doing, the paper contributes to the existing literature by providing a theoretical exposition and critique of various threads in social capital discourse, and linking these threads explicitly to community development practice. Distinctions between communitarian, institutional and critical approaches to social capital are elaborated, and the relationships between these three approaches and three models of community development-social planning, locality development, and social action-are discussed. The existing social capital literature is then critically examined in relation to three key themes common to both literatures: community integration, public participation, and power relations. This examination suggests that social capital cannot be conceived in isolation from economic and political structures, since social connections are contingent on, and structured by, access to material resources. This runs counter to many current policy discourses, which focus on the importance of connection and cohesion without addressing fundamental inequities in access to resources. This paper posits that approaches to community development and social capital should emphasise the importance of a conscious concern with social justice. A construction of social capital which explicitly endorses the importance of transformative social engagement, while at the same time recognising the potential negative consequences of social capital development, could help community organizers build communities in ways that truly promote health.     

How much do workers’ health examinations add to health and safety at the workplace? Occupational preventive usefulness of routine health examinations

ObjectiveDespite no evidence in favour, routine workers’ health examinations, mostly pre-employment and periodic, are extensively performed worldwide with important allocation of resources. In Spain they are performed within a theoretical job-specific health surveillance system. Our objective was to ascertain their occupational preventive usefulness from the perspective of occupational health professionals.MethodsCross sectional study. Online survey addressed to all physicians and nurses members of the Catalan Society of Safety and Occupational Medicine (n = 539) in 2011. Univariate and bivariate analyses of prevalence and prevalence differences of answers.ResultsResponse rate 53% (n = 285). According to more than 70% of respondents the health surveillance system isn’t cost-effective, doesn’t meet the goal of early detection of health damage related to work, and doesn’t contribute to improve the occupational risk prevention system. Further deficiencies were identified regarding specificity and scientific basis for health examinations, quality of collective health surveillance and referral of suspected cases to mutual insurance companies for diagnosis and treatment. Bivariate analysis showed a significantly more negative opinion for several items amongst physicians (versus nurses) and amongst professionals working in external prevention services (versus internal services).ConclusionsThis study raises serious concerns about how health examinations are performed within our workers’ health surveillance system, which should be reviewed to ensure the fulfilment of its occupational preventive objective. Our results might encourage other countries with similar practices to assess them in order to assure their fitness for purpose.     

How to identify an aspecific association? Epidemiological considerations on the study of health of office workers]

An epidemiological approach to the study of health conditions of office workers. Nowadays the work-relatedness of the majority of diseases occurring at the workplace is by no means obvious. The relationship to work environment and performance of work is one of several causative factors. However, the multifactorial origin of diseases is not at all a new concept since principles and methods for the study of the numerous factors playing a role in any association between exposure and disease are already available. The model of causal constellations developed by Rothman can be particularly useful for the investigation of "non-specific" associations, like those commonly occurring in office work. The study of the health conditions of office workers is faced with many difficulties, including the identification, measurement and classification of exposure variables and health outcomes. In designing these studies, particular attention should be devoted to aspects regarding sample size, length of observation and referent population.     

“Everyone was looking at you smiling”: East London residents' experiences of the 2012 Olympics and its legacy on the social determinants of health

Mega-sporting event regeneration, as a specific approach to urban renewal, uses impending host-city status as a catalyst for revitalisation and has the potential to improve health both through addressing deprivation and by promoting increased sport and physical activity among the host-city's population. This qualitative study explored how hosting of the London 2012 Games impacted upon the way East London residents perceived and experienced the social determinants of health in their local neighbourhood. We conducted narrative family interviews, go-along interviews and video focus group workshops with 66 Newham residents, aged 12–55 years, immediately after the Games. A narrative analytic approach examined accounts of health and wellbeing experiences in terms of neighbourhood change and the spectacle of the Games. Participants of this qualitative study generally welcomed the respite and the unexpected chance to live in a cleaner, safer and more unified environment. However, this positivity was underscored by an acute awareness that this was a very temporary situation and one that was intended to support the event rather than residents.     

“Never mind the logic,give me the numbers”: Former Australian health ministers' perspectives on the social determinants of health

The articulation of strong evidence and moral arguments about the importance of social determinants of health (SDH) and health equity has not led to commensurate action to address them. Policy windows open when, simultaneously, an issue is recognised as a problem, policy formulation and refinement happens and the political will for action is present. We report on qualitative interviews with 20 former Australian Federal, State or Territory health ministers conducted between September 2011 and January 2012 concerning their views about how and why the windows of policy opportunity on the SDH did or did not open during their tenure.Almost all ex-health ministers were aware of the existence of health inequalities and SDH but their complexity meant that this awareness rarely crystalised into a clear problem other than as a focus on high needs groups, especially Aboriginal people. Formulation of policies about SDH was assisted by cross-portfolio structures, policy entrepreneurs, and evidence from reviews and reports. It was hindered by the complexity of SDH policy, the dominance of medical power and paradigms and the weakness of the policy community advocating for SDH. The political stream was enabling when the general ideological climate was supportive of redistributive policies, the health care sector was not perceived to be in crisis, there was support for action from the head of government and cabinet colleagues, and no opposition from powerful lobby groups. There have been instances of Australian health policy which addressed the SDH over the past twenty five years but they are rare and the windows of opportunity that made them possible did not stay open for long.     

Can specially trained community care workers effectively support patients and their families in the home setting at the end of life?

Surveys indicate that many Australians would prefer to die at home, but relatively few do. Recognising that patients and their families may not have the support they need to enable end‐of‐life care at home, a consortium of care providers developed, and received funding to trial, the Palliative Care Home Support Program (PCHSP) across seven health districts in New South Wales, Australia. The programme aimed to supplement end‐of‐life care in the home provided by existing multidisciplinary community palliative care teams, with specialist supportive community care workers (CCWs). An evaluation of the service was undertaken, focussing on the self‐reported impact of the service on family carers (FCs), with triangulation of findings from community palliative care teams and CCWs. Service evaluation data were obtained through postal surveys and/or qualitative interviews with FCs, community palliative care teams and CCWs. FCs also reported the experience of their loved one based on 10 items drawn from the Quality of Death and Dying Questionnaire (QODD). Thematic analysis of surveys and interviews found that the support provided by CCWs was valued by FCs for: enabling choice (i.e. to realise end‐of‐life care in the home); providing practical assistance (“hands‐on”); and for emotional support and reassurance. This was corroborated by community palliative care teams and CCWs. Responses by FCs on the QODD items indicated that in the last week of life, effective control of symptoms was occurring and quality of life was being maintained. This study suggests that satisfactory outcomes for patients and their families who wish to have end‐of‐life care in the home can be enabled with the additional support of specially trained CCWs. A notable benefit of the PCHSP model, which provided specific palliative care vocational training to an existing community care workforce, was a relatively rapid increase in the palliative care workforce across the state.     

Mental health of community residents in the metropolitan Montreal area: some results of the "Santé Québec Survey".

In 1987, the "Santé Québec Survey" reached 2,696 individuals over 15 years old, living in the Montreal area. A self-administered questionnaire included two scales that measured the positive and negative aspects of mental health. Controlling for the effects of socio-demographic factors and global health status indicators, a multidimensional analysis computed the odds of being at risk of psychological wellbeing and psychological distress if exposed to social isolation or stressful life events. Results show that the quality of integration to the social environment is a better predictor of mental health than poverty by itself.     

Accumulated occupational class and self-rated health. Can information on previous experience of class further our understanding of the social gradient in health?

Previous research has shown a social gradient in health with better health for people in more advantaged positions in society. This research has mainly been on the relationship between current position and health, or social position in childhood and health, but less is known about the potential accumulative impact of positions held in adulthood. In this paper I use the economic activity histories from the Swedish Level of Living survey to examine the relationship between accumulated occupational class positions and health. Step-wise linear probability models are used to investigate how to best capture the potential association between class experience and self-rated health (SRH), and whether the effect of current class is modified when measures of accumulated class are included. I then further test the potentially lasting association between previous exposure to the health risk of working class by analysing only individuals currently in higher or intermediate level service class; the classes under least exposure.I find a positive association between accumulated experiences of working class and less than good SRH. Furthermore, even for employees currently in non-manual positions the risk for less than good SRH increases with each added year of previous experience within working class. This suggests that the social gradient can be both accumulative and lasting, and that more information on the mechanisms of health disparities can be found by taking detailed information on peoples' pasts into account. Although gender differences in health are not a focus in this paper, results also indicate that the influence of class experiences on health might differ between men and women.     

Do changes in neighborhood social context mediate the effects of the moving to opportunity experiment on adolescent mental health?

This study investigated whether changes in neighborhood context induced by neighborhood relocation mediated the impact of the Moving to Opportunity (MTO) housing voucher experiment on adolescent mental health. Mediators included participant-reported neighborhood safety, social control, disorder, and externally-collected neighborhood collective efficacy. For treatment group members, improvement in neighborhood disorder and drug activity partially explained MTO's beneficial effects on girls' distress. Improvement in neighborhood disorder, violent victimization, and informal social control helped counteract MTO's adverse effects on boys' behavioral problems, but not distress. Housing mobility policy targeting neighborhood improvements may improve mental health for adolescent girls, and mitigate harmful effects for boys.
