The ongoing obesity epidemic represents a global public health crisis that contributes to poor health outcomes, reduced quality of life, and >2.8 million deaths each year. Obesity is relapsing, progressive, and heterogeneous. It is considered a chronic disease by the World Obesity Federation (WOF) and a chronic condition by the World Heart Federation (WHF). People living with overweight/obesity are at greater risk for cardiovascular (CV) morbidity and mortality. Increased adiposity (body fat), particularly visceral/abdominal fat, is linked to CV risk and CV disease (CVD) via multiple direct and indirect pathophysiological mechanisms. The development of CVD is driven, in part, by obesity-related metabolic, endocrinologic, immunologic, structural, humoral, haemodynamic, and functional alterations. The complex multifaceted nature of these mechanisms can be challenging to understand and address in clinical practice. People living with obesity and CVD often have concurrent chronic physical or psychological disorders (multimorbidity) requiring multidisciplinary care pathways and polypharmacy. Evidence indicates that intentional weight loss (particularly when substantial) lowers CVD risk among people with overweight/obesity. Long-term weight loss and maintenance require ongoing commitment from both the individual and those responsible for their care. This position paper, developed by the WOF and the WHF, aims to improve understanding of the direct and indirect links between overweight/obesity and CVD, the key controversies in this area and evidence relating to cardiometabolic outcomes with available weight management options. Finally, an action plan for clinicians provides recommendations to help in identifying and addressing the risks of obesity-related CVD (recognizing resource and support variances between countries).

Background: Secondary prevention lifestyle and pharmacological treatment of atherosclerotic cardiovascular disease (ASCVD) reduce a high proportion of recurrent events and mortality. However, significant gaps exist between guideline recommendations and usual clinical practice. Objectives: Describe the state of the art, the roadblocks, and successful strategies to overcome them in ASCVD secondary prevention management. Methods: A writing group reviewed guidelines and research papers and received inputs from an international committee composed of cardiovascular prevention and health systems experts about the article’s structure, content, and draft. Finally, an external expert group reviewed the paper. Results: Smoking cessation, physical activity, diet and weight management, antiplatelets, statins, beta-blockers, renin-angiotensin-aldosterone system inhibitors, and cardiac rehabilitation reduce events and mortality. Potential roadblocks may occur at the individual, healthcare provider, and health system levels and include lack of access to healthcare and medicines, clinical inertia, lack of primary care infrastructure or built environments that support preventive cardiovascular health behaviours. Possible solutions include improving health literacy, self-management strategies, national policies to improve lifestyle and access to secondary prevention medication (including fix-dose combination therapy), implementing rehabilitation programs, and incorporating digital health interventions. Digital tools are being examined in a range of settings from enhancing self-management, risk factor control, and cardiac rehab. Conclusions: Effective strategies for secondary prevention management exist, but there are barriers to their implementation. WHF roadmaps can facilitate the development of a strategic plan to identify and implement local and national level approaches for improving secondary prevention.

This study had the following objectives: (1) To look into the public health response of the country facing the COVID-19 outbreak, and (2) To examine the effectiveness of the measures being undertaken to contain the outbreak. The research method used was the analysis of all documents/discourses pertaining to the public health response of Mauritius towards COVID-19. We compiled data over the period of 17 January 2020 to 15 May 2020 as and when they were communicated. This study revealed three main themes: (1) Prevention strategy, (2) Outbreak management strategy and (3) Communication strategy. In light of the qualitative findings and the numerical data provided by the Mauritian authorities, we appraise the public health response of Mauritius. After demonstrating the effectiveness of the public health strategies undertaken by the Mauritian government, we draw the lessons learnt from the experience of Mauritius. These lessons have implications for practice by middle-income countries and/or small island developing states facing a communicable disease outbreak.

Background: Almost 80% of global tobacco usage is concentrated in low- and-middle-income countries (LMICs) like India. Added to this, there is dearth of dedicated tobacco cessation specialist services in healthcare settings in these regions. Identification of challenges in the delivery of cessation interventions and understanding the experiences of tobacco users will aid in formulating successful quit strategies. Objectives: This qualitative study in India aimed to understand the perspectives of tobacco-using patients in healthcare facilities regarding tobacco use and cessation. Methods: This qualitative study was conducted in urban and rural areas of four study sites, two each in the North and South India. Using purposive sampling, patients who were tobacco users were selected from healthcare facilities. The interviews were transcribed, coded and organised into themes. Analysis was done using NVivo 10 software. Results: A total of 22 in-depth interviews were conducted on participants aged 23 to 80 years who were either current or past tobacco users. A majority of the participants were aware of their increased health risks associated with tobacco consumption and had attempted quitting; however, barriers such as peer influence, formed habit, certain cultural barriers and the addictive nature of nicotine prevented them from successfully quitting. Familial and peer support, the government’s role in spreading public awareness, and limiting the sale of tobacco were stated as facilitators for tobacco cessation. Conclusions: The findings of this study point out that despite awareness of the perils of tobacco among smokers, there are various barriers and beliefs related to tobacco use and cessation. These findings would prove advantageous for policy-makers to implement and promote addiction treatment programmes for successful tobacco cessation efforts. In order to optimise strategies, policies must be well informed by ongoing dialogue between the public, service providers and policy-makers.
