Does rapid urbanization aggravate health disparities? Reflections on the epidemiological transition in Pune, India

Background: Rapid urbanization in low- and middle-income countries reinforces risk and epidemiological transition in urban societies, which are characterized by high socioeconomic gradients. Limited availability of disaggregated morbidity data in these settings impedes research on epidemiological profiles of different population subgroups. Objective: The study aimed to analyze the epidemiological transition in the emerging megacity of Pune with respect to changing morbidity and mortality patterns, also taking into consideration health disparities among different socioeconomic groups. Design: A mixed-methods approach was used, comprising secondary analysis of mortality data, a survey among 900 households in six neighborhoods with different socioeconomic profiles, 46 in-depth interviews with laypeople, and expert interviews with 37 health care providers and 22 other health care workers. Results: The mortality data account for an epidemiological transition with an increasing number of deaths due to non-communicable diseases (NCDs) in Pune. The share of deaths due to infectious and parasitic diseases remained nearly constant, though the cause of deaths changed considerably within this group. The survey data and expert interviews indicated a slightly higher prevalence of diabetes and hypertension among higher socioeconomic groups, but a higher incidence and more frequent complications and comorbidities in lower socioeconomic groups. Although the self-reported morbidity for malaria, gastroenteritis, and tuberculosis did not show a socioeconomic pattern, experts estimated the prevalence in lower socioeconomic groups to be higher, though all groups in Pune would be affected. Conclusions: The rising burden of NCDs among all socioeconomic groups and the concurrent persistence of communicable diseases pose a major challenge for public health. Improvement of urban health requires a stronger focus on health promotion and disease prevention for all socioeconomic groups with a holistic understanding of urban health. In order to derive evidence-based solutions and interventions, routine surveillance data become indispensable

Tensile Behavior and Diffusion of Moisture through Flax Fibers by Desorption Method

There has been a substantial increase in the usage of natural fibers and biodegradable polymers in composite materials due to the recent focus on sustainability of materials. Flax fibers have exhibited higher mechanical properties compared to most other natural fibers available. However, one of the major challenges faced in the use of flax fiber is its hydrophilicity. In this study, the tensile behavior of flax fiber tows removed from commercially available woven fabrics were investigated at different moisture levels. The breaking tenacity of fiber tows was shown to increase with an increase in moisture content of up to 25%. After this point, additional absorption of moisture resulted in a decrease of fiber tenacity. In addition, the diffusion process through flax fiber mat with different areal densities was investigated and the diffusion coefficients were determined using the desorption curves. Diffusion rates were not found to significantly change with varying areal densities of 200 to 400 gsm, but were significantly different when exposed to temperatures of 55 °C versus 80 °C

Community Health Workers as Influential Health System Actors and not "Just Another Pair Of Hands"

BACKGROUND: Over the last 20 years, community health workers (CHWs) have become a mainstay of human resources for health in many low- and middle-income countries (LMICs). A large body of research chronicles CHWs' experience of their work. In this study we focus on 2 narratives that stand out in the literature. The first is the idea that social, economic and health system contexts intersect to undermine CHWs' experience of their work, and that a key factor underpinning this experience is that LMIC health systems tend to view CHWs as just an 'extra pair of hands' to be called upon to provide 'technical fixes.' In this study we show the dynamic and evolving nature of CHW programmes and CHW identities and the need, therefore, for new understandings. METHODS: A qualitative case study was carried out of the Indian CHW program (CHWs are called accredited social health activists: ASHAs). It aimed to answer the research question: How do ASHAs experience being CHWs, and what shapes their experience and performance? In depth interviews were conducted with 32 purposively selected ASHAs and key informants. Analysis was focused on interpreting and on developing analytical accounts of ASHAs' experiences of being CHWs; it was iterative and occurred throughout the research. Interviews were transcribed verbatim and transcripts were analysed using a framework approach (with Nvivo 11). RESULTS: CHWs resent being treated as just another pair of hands at the beck and call of formal health workers. The experience of being a CHW is evolving, and many are accumulating substantial social capital over time - emerging as influential social actors in the communities they serve. CHWs are covertly and overtly acting to subvert the structural forces that undermine their performance and work experience. CONCLUSION: CHWs have the potential to be influential actors in the communities they serve and in frontline health services. Health systems and health researchers need to be cognizant of and consciously engage with this emerging global social dynamic around CHWs. Such an approach can help guide the development of optimal strategies to support CHWs to fulfil their role in achieving health and social development goals
