Climate change and human health in Vietnam: a systematic review and additional analyses on current impacts, future risk, and adaptation.

This study aims to investigate climate change's impact on health and adaptation in Vietnam through a systematic review and additional analyses of heat exposure, heat vulnerability, awareness and engagement, and projected health costs. Out of 127 reviewed studies, findings indicated the wider spread of infectious diseases, and increased mortality and hospitalisation risks associated with extreme heat, droughts, and floods. However, there are few studies addressing health cost, awareness, engagement, adaptation, and policy. Additional analyses showed rising heatwave exposure across Vietnam and global above-average vulnerability to heat. By 2050, climate change is projected to cost up to USD1-3B in healthcare costs, USD3-20B in premature deaths, and USD6-23B in work loss. Despite increased media focus on climate and health, a gap between public and government publications highlighted the need for more governmental engagement. Vietnam's climate policies have faced implementation challenges, including top-down approaches, lack of cooperation, low adaptive capacity, and limited resources.

Practical Strategies for Improving Sustainability and Scale-up of Noncommunicable Disease-related Public Health Interventions: Lessons from the Better Health Program in Southeast Asia.

Introduction: The Better Health Program has been addressing key health system issues in the prevention and control of noncommunicable diseases (NCDs) in Malaysia, Thailand, Vietnam, and the Philippines. As the program comes to an end, the sustainability and scaling-up of issues have assumed importance. Objectives: The objective is to assess how well sustainability and scale-up strategies have been integrated into the design and implementation of a 3-year multicountry technical program; to explore enablers and barriers of sustainability and scaling up; and to identify practical strategies that can improve sustainability and scale-up of Better Health Program interventions. Methods: We applied a staged approach to explore barriers and enablers and to identify practical strategies to improve sustainability and scale-up of four NCD interventions: community-based obesity prevention, front-of-pack labeling, local learning networks (LLNs), and NCD surveillance. We extracted evidence from peer-reviewed literature and local documents. We also conducted in-depth interviews with the implementation teams and key stakeholders. We conducted a thematic synthesis of the resulting information to identify practical strategies that improve sustainability and scale-up of the four interventions. Results: Strong engagement of stakeholders at higher levels of the health system was identified as the main enabler, while limited funding and commitment from local governments were identified as a key barrier to sustainability and scale-up. Strengthening the social and institutional anchors of community health volunteers, enhancing evidence-based advocacy for front-of-pack labeling, trailblazing the LLN innovation, and securing the commitment of local governments in the implementation of NCD surveillance were among the key strategies for improving sustainability and scale-up of Better Health Program interventions in Malaysia, Thailand, Philippines, and Vietnam, respectively. Conclusions: This study identified practical strategies for improving sustainability and scale-up of NCD-related interventions. Implementation of the strategies that had high priority and feasibility will improve the sustainability of critical elements of the program in the respective countries.

Putting non-communicable disease data to work in Vietnam: an investigation of community health surveillance capacity.

INTRODUCTION: Despite the public health system's critical role in non-communicable disease (NCD) surveillance in Vietnam, limited evidence exists on the implementation of NCD surveillance activities within these systems and the need for capacity building across different system levels to meet expected NCD surveillance goals. This study aimed to evaluate the status of and describe factors affecting the implementation of NCD surveillance activities and to identify the NCD surveillance capacity building needs of the public health system in Vietnam. METHODS: We used a mixed-methods approach in four provinces, conducting self-completed surveys of staff from six Preventive Medicine Institutes (PHI), 53 Centres for Disease Control (CDC) and 148 commune health stations (CHS), as well as 14 in-depth interviews and 22 focus group discussions at four PHI, four CDC, and eight district health centres and CHS. RESULTS: Study findings highlighted that although Vietnam has a well-functioning NCD surveillance system, a number of quality issues related to NCD surveillance data were salient. Multifactorial reasons were identified for incomplete, unconfirmed, and inaccurate mortality data and current disease surveillance data. Data on NCD management and treatment were reported to be of better quality than data for screening, targeted treatment, and counselling communication. Main factors affected the effective implementation of NCD surveillance, namely lack of complete and specific guidelines for NCD surveillance, limitations in human resource capacity within NCD departments, and shortage of funding for NCD surveillance activities. CONCLUSION: Study findings provide practical strategies for strengthening health system capacity for NCD surveillance through developing policies, guidelines, and standardised tools to guide NCD surveillance and a road map for integrated NCD surveillance, developing training packages and manuals for all levels of the health system, and conducting utilisation-focused surveillance training programs.

The effectiveness of workplace health promotion in low- and middle-income countries.

Although many literature reviews synthesize literature regarding workplace health promotion (WHP) interventions, systematic reviews on the effectiveness of and factors influencing the operation of WHP activities in low- and middle-income countries (LMIC) are scarce. Therefore, we systematically reviewed evaluation studies to examine the effectiveness and factors related to the implementation of WHP programmes in LMIC. Twenty-six peer-reviewed and grey evaluation studies, published before November 2017, were included from electronic databases (PubMed, The Cochrane Library, PsycINFO, EMBASE and Web of Science) and manual searching. The results revealed that WHP intervention in LMIC was effective in reducing health risks in a wide range of industries and settings, including in resource-poor contexts such as small enterprises and the manufacturing industry. The main factors positively influencing the effectiveness of the intervention are long intervention time period, and needs-based and active intervention strategies. In addition, commitment from workplace leaders, the involvement of workers and support from authorities and professionals are factors contributing to a successful WHP programme. However, the evidence regarding the effectiveness of WHP in LMIC regarding the health outcomes and business productivity is inconclusive due to the several remaining methodological limitations. Future developments of more rigorous methods of evaluating the effectiveness of WHP activities should be addressed to produce higher-quality evidence that would inform future practice.

Integrative settings approach to workplace health promotion to address contemporary challenges for worker health in the Asia-Pacific.

Workplaces in the rapidly industrializing Asia-Pacific region face growing pressures from high-speed development driven by global competition, migration and the aging of the workforce. Apart from addressing work-related injuries, workplaces in the region also have to deal with increasing occupational stress, chronic diseases and their associated socio-economic burden. Meanwhile, interventions in workplace health are still dominated by a narrow behavioral change model. To this end, the integrative workplace health promotion model, initiated by the World Health Organization from successful post-1990 pilot projects, emerges as a timely, comprehensive and appropriate means to manage contemporary workplace health and safety issues in the region. In this paper, we highlight the key workplace health challenges in the Asia-Pacific region and the utility of the integrative workplace health promotion model in addressing them. We provide a brief overview of the pressing challenges confronting workplaces in the region, then explain the why, what and how of integrative workplace health promotion. We illustrate this model by reviewing successful examples of good practice and evidence of their achievements from workplace health promotion programs in Asia-Pacific from 2002 to date, with specific attention to government-led workplace health promotion programs in Shanghai, Singapore and Taiwan. Drawing from these successful examples, we recommend government policies and facilitating strategies needed to guide, support and sustain industries in implementing integrative workplace health promotion. We conclude that consistent supportive government policies, coupled with facilitation by international bodies towards capacity and professional network building, are crucial to developing and sustaining healthy workplaces in the region.
