Background: In Tanzania, the distribution and coverage of insecticide-treated nets (ITNs) is inequitable. Arguments about the most effective and equitable approach to distributing ITNs centre around whether to provide ITNs free of charge or continue with existing social marketing strategies. The Government has decided to provide free ITNs to all children under five in the country. It is still uncertain whether this strategy will achieve equitable coverage and use. This study examined the equity implications of ownership and use of ITNs in households from different socioeconomic quintiles in a district with free ITNs and a district without free ITN distribution. Methods: A cross-sectional comparative household survey was conducted in two districts: Mpanda in Rukwa Region (with free ITN roll out) and Kisarawe in Coast region (without free ITNs). Heads of 314 households were interviewed in Mpanda and Kisarawe. The concentration index was estimated and regression analysis was performed to compare socioeconomic inequalities in ownership and use of ITNs. Results: Ownership of ITNs increased from 29% in the 2007/08 national survey to 90% after the roll out of free ITNs in Mpanda, and use increased from 13% to 77%. Inequality was considerably lower in Mpanda, with nearly perfect equality in use (concentration index 0.009) and ownership (concentration index 0.010). In Kisarawe, ownership of ITNs increased from 48% in the 2007/08 national survey to 53%, with a marked inequality concentration index 0.132. ITN use in Kisarawe district was 42% with a pro rich concentration index of 0.027. Conclusions: The results shed some light on the possibilities of reducing inequality in ownership and use of ITNs and attaining Roll Back Malaria and Millennium Development Goals through the provision of free ITNs to all. This has the potential to decrease the burden of disease and reduce disparity in disease outcome. ; publishedVersion

Background: The implementation of decentralisation reforms in the health sector of Tanzania started in the 1980s. These reforms were intended to relinquish substantial powers and resources to districts to improve the development of the health sector. Little is known about the impact of decentralisation on recruitment and distribution of health workers at the district level. Reported difficulties in recruiting health workers to remote districts led the Government of Tanzania to partly re-instate central recruitment of health workers in 2006. The effects of this policy change are not yet documented. This study highlights the experiences and challenges associated with decentralisation and the partial re-centralisation in relation to the recruitment and distribution of health workers. Methods: An exploratory qualitative study was conducted among informants recruited from five underserved, remote districts of mainland Tanzania. Additional informants were recruited from the central government, the NGO sector, international organisations and academia. A comparison of decentralised and the reinstated centralised systems was carried out in order to draw lessons necessary for improving recruitment, distribution and retention of health workers. Results: The study has shown that recruitment of health workers under a decentralised arrangement has not only been characterised by complex bureaucratic procedures, but by severe delays and sometimes failure to get the required health workers. The study also revealed that recruitment of highly skilled health workers under decentralised arrangements may be both very difficult and expensive. Decentralised recruitment was perceived to be more effective in improving retention of the lower cadre health workers within the districts. In contrast, the centralised arrangement was perceived to be more effective both in recruiting qualified staff and balancing their distribution across districts, but poor in ensuring the retention of employees. Conclusion: A combination of centralised and decentralised recruitment represents a promising hybrid form of health sector organisation in managing human resources by bringing the benefits of two worlds together. In order to ensure that the potential benefits of the two approaches are effectively integrated, careful balancing defining the local-central relationships in the management of human resources needs to be worked out. ; publishedVersion

Background: Several countries are discussing new legislation on the ban of smoking in public places, and on the acceptable levels of traffic-related air pollutants. It is therefore useful to estimate the burden of disease associated with indoor and outdoor air pollution. Methods: We have estimated exposure to Environmental Tobacco Smoke (ETS) and to air pollution in never smokers and ex-smokers in a large prospective study in 10 European countries (European Prospective Investigation into Cancer and Nutrition)(N = 520,000). We report estimates of the proportion of lung cancers attributable to ETS and air pollution in this population. Results: The proportion of lung cancers in never- and ex-smokers attributable to ETS was estimated as between 16 and 24%, mainly due to the contribution of work-related exposure. We have also estimated that 5–7% of lung cancers in European never smokers and ex-smokers are attributable to high levels of air pollution, as expressed by NO2 or proximity to heavy traffic roads. NO2 is the expression of a mixture of combustion (traffic-related) particles and gases, and is also related to power plants and waste incinerator emissions. Discussion: We have estimated risks of lung cancer attributable to ETS and traffic-related air pollution in a large prospective study in Europe. Information bias can be ruled out due to the prospective design, and we have thoroughly controlled for potential confounders, including restriction to never smokers and long-term ex-smokers. Concerning traffic-related air pollution, the thresholds for indicators of exposure we have used are rather strict, i.e. they correspond to the high levels of exposure that characterize mainly Southern European countries (levels of NO2 in Denmark and Sweden are closer to 10–20 ug/m3, whereas levels in Italy are around 30 or 40, or higher). Therefore, further reduction in exposure levels below 30 ug/m3 would correspond to additional lung cancer cases prevented, and our estimate of 5–7% is likely to be an underestimate. Overall, our prospective study draws attention to the need for strict legislation concerning the quality of air in Europe.

Aims: In three days at the beginning of the COVID-19 pandemic, the Copenhagen Emergency Medical Services developed a digital diagnostic device. The purpose was to assess and triage potential COVID-19 symptoms and to reduce the number of calls to public health-care helplines. The device was used almost 150,000 times in a few weeks and was described by politicians and administrators as a solution and success. However, high usage cannot serve as the sole criterion of success. What might be adequate criteria? And should digital triage for citizens by default be considered low risk? Methods: This paper reflects on the uncertain aspects of the performance, risks and issues of accountability pertaining to the digital diagnostic device in order to draw lessons for future improvements. The analysis is based on the principles of evidence-based medicine (EBM), the EU and US regulations of medical devices and the taxonomy of uncertainty in health care by Han et al. Results: Lessons for future digital devices are (a) the need for clear criteria of success, (b) the importance of awareness of other severe diseases when triaging, (c) the priority of designing the device to collect data for evaluation and (d) clear allocation of responsibilities. Conclusions: A device meant to substitute triage for citizens according to its own criteria of success should not by default be considered as low risk. In a pandemic age dependent on digitalisation, it is therefore important not to abandon the ethos of EBM, but instead to prepare the ground for new ways of building evidence of effect.

The study aimed at investigating the concentrations and geographical patterns of 11 polychlorinated biphenyls (PCBs) and 15 organochlorine pesticides (OCPs) in reindeer muscle samples (n = 100) collected from 10 grazing districts in Norway, 2009. Concentrations were examined for patterns related to geographical region as well as age and sex of animals. Concentrations measured for PCBs and OCPs in reindeer meat samples were generally low. Geographical patterns were revealed and districts with previous mining activities, military trenches, or those that were in the vicinity of the Russian border exhibited slightly elevated concentrations compared to other districts. Calves (10 months) exhibited higher concentrations than young (1.5 year) and old animals (>2 years) adjusted for sex, whereas males exhibited higher concentrations than females, adjusted for age. All PCB congeners inter-correlated strongly with each other, whereas oxy-chlordane and heptachlor epoxide were the strongest inter-correlated OCP compounds. Concentrations of PCBs and OCPs in reindeer meat were all considerably lower than the maximum levels set for those contaminants in foodstuffs for safe human consumption by the European Commission. Thus, reindeer meat is not likely to be a substantial contributor to the human body burden of persistent organic pollutants.

Background - Physical inactivity and chronic pain are both major public health concerns worldwide. Although the health benefits of regular physical exercise are well-documented, few large epidemiological studies have investigated the association between specific domains of physical exercise and chronic pain in young adults. We sought to investigate the association between frequency, intensity and duration of physical exercise, and chronic pain. Methods - Data stem from the SHoT2018-study, a national health survey for higher education in Norway, in which 36,625 fulltime students aged 18–35 years completed all relevant questionnaires. Chronic pain, defined according to the International Classification of Diseases 11th Revision (ICD-11), was assessed with a newly developed hierarchical digital instrument for reporting both distribution and characteristics of pain in predefined body regions. Physical exercise was assessed using three sets of questions, measuring the number of times exercising each week, and the average intensity and the number of hours each time. Results - The majority (54%) of the students reported chronic pain in at least one location, and the prevalence was especially high among women. The overall pattern was an inverse dose-response association between exercise and chronic pain: the more frequent, harder or longer the physical exercise, the lower the risk of chronic pain. Similar findings were generally also observed for the number of pain locations: frequent exercise was associated with fewer pain locations. Adjusting for demographical, lifestyle factors and depression had little effect on the magnitude of the associations. Conclusion - Given the many health benefits of regular exercise, there is much to be gained in facilitating college and university students to be more physically active, ideally, thru a joint responsibility between political and educational institutions. Due to the cross-sectional nature of the study, one should be careful to draw a firm conclusion about the direction of causality.

Alcohol-related harm has gained increased attention in high-income countries (HICs) in recent years which, alongside government regulation, has effected a reduction in alcohol consumption. The alcohol industry has turned its attention to low-income and middle-income country (LMIC) markets as a new source of growth and profit, prompting increased consumption in LMICS. Alcohol use in LMICs is also increasing. There is a need to understand particularly in LMICs the impact of industry strategy in shaping local contexts of alcohol use. We draw on conceptualisations from food systems research, and research on the commercial determinants of health, to develop a new approach for framing alcohol research and discuss implications for alcohol research, particularly in LMICs, focusing on South Africa as an illustrative example. We propose a conceptualisation of the 'alcohol environment' as the system of alcohol provision, acquisition and consumption—including, critically, industry advertising and marketing—along with the political, economic and regulatory context of the alcohol industry that mediates people's alcohol drinking patterns and behaviours. While each country and region is different in terms of its context of alcohol use, we contrast several broadly distinct features of alcohol environments in LMICs and HICs. Improving understanding of the full spectrum of influences on drinking behaviour, particularly in LMICs, is vital to inform the design of interventions and policies to facilitate healthier environments and reduce the harms associated with alcohol consumption. Our framework for undertaking alcohol research may be used to structure mixed methods empirical research examining the role of the alcohol environment particularly in LMICs.

Background - Globally, there is a huge lack of relevant research about widespread lifestyle diseases and living conditions in indigenous communities. Northern and Middle Norway have a history of multiple ethnic groups and the Sami has been acknowledged as the indigenous people of Norway by the Norwegian State. The SAMINOR 2 Clinical Survey, a part of the SAMINOR Study, was carried out to provide health information about the Sami population in Norway. Methods - The cross-sectional population-based SAMINOR 2 Clinical Survey consists of both questionnaires and a clinical examination performed in 10 municipalities during 2012–2014. Results - In total, 6004 men and women (participation rate 48%) aged 40–79 years took part in this study. In inland Finnmark, the Sami are in the majority (80–90%) as opposed to the coastline of Troms and Nordland, where the Sami population form a minority (20%). More women than men participated (54% versus 43%, respectively). Obesity was prevalent in this sample and a high mean glycated haemoglobin was observed. Conclusions - This article describes the methods and data collection of the SAMINOR 2 Clinical Survey and presents some characteristics of the sample. The definition of ethnic groups is a core question in the survey and includes several criteria. To ensure that indigenous values and priorities are reflected in the research themes, we recommend that future research projects be directed in close collaboration with the Sami Parliament and the local communities.

Even greater gains in GDP (PPP) were seen for Moscow, the Russian capital, reaching $43 000 in 2015 and with a life expectancy of 75·5 years. We aimed to investigate whether mortality levels now seen in Russia are consistent with what would be expected given this new level of per-capita wealth. Methods - We used per-capita GDP (PPP) and life expectancy from 61 countries in 2014–15, plus those of Russia as a whole and its capital Moscow, to construct a Preston curve expressing the relationship between mortality and national wealth and to examine the positions of Russia and other populations relative to this curve. We adjusted life expectancy values for Moscow for underestimation of mortality at older ages. For comparison, we constructed another Preston curve based on the same set of countries for the year 2005. We used the stepwise replacement algorithm to decompose mortality differences between Russia or Moscow and comparator countries with similar incomes into age and cause-of-death components. Findings - Life expectancy in 2015 for both Russia and Moscow lay below the Preston-curve-based expectations by 6·5 years and 4·9 years, respectively. In 2015, Russia had a lower per-capita income than 36 of the comparator countries but lower life expectancy than 60 comparator countries. However, the gaps between the observed and the Preston-expected life expectancy values for Russia have diminished by about 25% since 2005, when the life expectancy gap was 8·9 years for Russia and 6·6 years for Moscow. When compared with countries with similar level of income, the largest part of the life expectancy deficit was produced by working-age mortality from external causes for Russia and cardiovascular disease at older ages for Moscow. Interpretation - Given the economic wealth of Russia, its life expectancy could be substantially higher. Sustaining the progress seen over the past decade depends on the ability of the Russian Government and society to devote adequate resources to people's health.

Most research on transactional sex frame men as buyers and females as sellers of sex. We conducted a systematic mapping review of the empirical research on transactional sex where women form the demand (buyer) and men the supply (seller). We included 46 studies, of which 25 explicitly researched women as buyers of sex from male sellers, and 21 studies where this topic was a subset of larger topics. The majority of research on women who trade sexual services from men is published in the last 15 years, by female researchers, using cross-sectional or qualitative/ethnographic design, and from the perspective of males as sellers. While the women appear to be mature and financially independent, the men are young and socioeconomically vulnerable. Men's main motivation for the sexual-economic exchanges with women is financial, whereas women's motivations are largely satisfaction of sexual needs and a stereotyped erotic fantasy of black male hypersexuality. Condoms are often not used. Our review shows that there is a – possibly growing and diversifying – female consumer demand for male sexual services, and transactional sex where women trade sex from men is a complex social phenomenon firmly grounded in social, economic, political, and sexual relations.

Setting - This study was conducted in a secondary care rehabilitation centre in Gaza, Palestine. The clinic is Gaza's sole provider of artificial limbs. Participants - We included 254 civilian Palestinians who had survived but lost one or more limb(s) during military incursions from 2006 to 2016. We included patients with surgically treated amputation injuries who attended physical rehabilitation at a specialist prosthesis centre in Gaza. Amputees with injuries prior to 2006 or non-military related injuries were excluded. We assessed their pain and psychological stress using the General Health Questionnaire (GHQ-12). We used income, amputation severity scored by proximity to torso, current employment status, loss of family members and loss of home as independent variables. Results - The amputees median age was 23 years at the time of trauma, while a median of 4.3 years had passed from trauma to study inclusion. Nine of 10 were male, while 43 were children when they were amputated (17%≤18 years). One hundred and ninety-one (75%) were unemployed and 112 (44%) reported unemployment caused by being amputated. Pain was the most frequent problem, and 80 amputees (32%) reported to suffer from daily pain. Family income was significantly correlated with the physical pain (OR=0.54, CI 0.36 to 0.80, p=0.002). Psychological distress was higher among unemployed amputees (OR=1.36, CI 1.07 to 1.72, p=0.011). We found no association between psychological distress (GHQ-scores) and the extent of the initial amputation. Conclusion - Pain and psychological distress following war-related extremity amputation of one or more limbs correlated stronger with deteriorated family economy and being unemployed than with the anatomical and medical severity of extremity amputations.

The official published article is available online at https://doi.org/10.1176/appi.ps.201700505. ; The Arctic Council, a collaborative forum among governments and Arctic communities, has highlighted the problem of suicide and potential solutions. The mental health initiative during the United States chairmanship, Reducing the Incidence of Suicide in Indigenous Groups: Strengths United Through Networks (RISING SUN), used a Delphi methodology complemented by face-to-face stakeholder discussions to identify outcomes to evaluate suicide prevention interventions. RISING SUN underscored that multilevel suicide prevention initiatives require mobilizing resources and enacting policies that promote the capacity for wellness, for example, by reducing adverse childhood experiences, increasing social equity, and mitigating the effects of colonization and poverty.

Source at https://www.hca.westernsydney.edu.au/gmjau. ; The aim of this article is to explore how the political, technological and economic development of recent decades has influenced the identity construction of Sami people with disabilities. While Sami identity work is described as a continuous process carried out in everyday life, the subject is addressed through a presentation and discussion of three narratives. The analysis demonstrates how different types of development have expanded access for Samis with disabilities to participate in traditional Sami activities in many ways and, as such, have increased their opportunities to identify themselves as Sami. At the same time, however, changes in laws and regulations concerning ownership and use of land and sea resources seem to constitute political barriers that hinder disabled Samis from pursuing traditional Sami occupations and activities such as fishing and reindeer herding. Furthermore, 'cultural blindness' among professionals within the welfare system seems to block opportunities for Samis with disabilities to access their own culture through language and traditional Sami way of life. This lack of connection to traditional Sami activities is problematic as it may lead to the perception among both disabled Sami individuals and other Samis that these individuals are not entitled to define themselves as Sami.

Source at: http://doi.org/10.3390/ijerph14121462 ; Circumpolar regions, and the nations within which they reside, have recently gained international attention because of shared and pressing public policy issues such as climate change, resource development, endangered wildlife and sovereignty disputes. In a call for national and circumpolar action on shared areas of concern, the Arctic states health ministers recently met and signed a declaration that identified shared priorities for international cooperation. Among the areas for collaboration raised, the declaration highlighted the importance of enhancing intercultural understanding, promoting culturally appropriate health care delivery and strengthening circumpolar collaboration in culturally appropriate health care delivery. This paper responds to the opportunity for further study to fully understand indigenous values and contexts, and presents these as they may apply to a framework that will support international comparisons and systems improvements within circumpolar regions. We explored the value base of indigenous peoples and provide considerations on how these values might interface with national values, health systems values and value bases between indigenous nations particularly in the context of health system policy-making that is inevitably shared between indigenous communities and jurisdictional or federal governments. Through a mixed methods nominal consensus process, nine values were identified and described: humanity, cultural responsiveness, teaching, nourishment, community voice, kinship, respect, holism and empowerment.

Manuscript. Source at http://dx.doi.org/10.1136/oemed-2016-104170 ; Objective: To investigate external-cause mortality among 21 609 Norwegian male military peacekeepers deployed to Lebanon during 1978–1998. Methods: The cohort was followed from first day of deployment through 2013, and mortality during deployment and post discharge was assessed using standardized mortality ratios (SMR) calculated from national rates in Norway. Poisson regression was used to see the effect of high- versus low-conflict exposure. Results: For the total cohort, external-cause mortality was within expected values during deployment (SMR=0.80) and post discharge (SMR=1.05). In the low-conflict exposure group, a lower mortality from all external causes (SMR=0.77), transport accidents (SMR=0.55), and accidental poisoning (SMR=0.53) was seen. The high-conflict exposure group showed an elevated mortality from all external causes (SMR=1.20), transport accidents (SMR=1.51), and suicide (SMR=1.30), but these risks were elevated only during the first 5 years after discharge. This group also showed elevated mortality from all external causes (RR=1.49), and for transport accidents (RR=3.30) when compared with the low-conflict exposure group. Conclusions: Overall external-cause mortality among our peacekeepers was equal to national rates during deployment and post discharge. High conflict exposure was associated with elevated mortality from all external causes, transport accidents, and suicide during the first 5 years after discharge from service.
