The Global Syndemic of Obesity, Undernutrition, and Climate Change: The Lancet Commission report

Dynamics of the double burden of malnutrition and the changing nutrition reality.

The linkage of individuals with obesity and COVID-19 is controversial and lacks systematic reviews. After a systematic search of the Chinese and English language literature on COVID-19, 75 studies were used to conduct a series of meta-analyses on the relationship of individuals with obesity-COVID-19 over the full spectrum from risk to mortality. A systematic review of the mechanistic pathways for COVID-19 and individuals with obesity is presented. Pooled analysis show individuals with obesity were more at risk for COVID-19 positive, >46.0% higher (OR = 1.46; 95% CI, 1.30-1.65; p < 0.0001); for hospitalization, 113% higher (OR = 2.13; 95% CI, 1.74-2.60; p < 0.0001); for ICU admission, 74% higher (OR = 1.74; 95% CI, 1.46-2.08); and for mortality, 48% increase in deaths (OR = 1.48; 95% CI, 1.22-1.80; p < 0.001). Mechanistic pathways for individuals with obesity are presented in depth for factors linked with COVID-19 risk, severity and their potential for diminished therapeutic and prophylactic treatments among these individuals. Individuals with obesity are linked with large significant increases in morbidity and mortality from COVID-19. There are many mechanisms that jointly explain this impact. A major concern is that vaccines will be less effective for the individuals with obesity.

Individuals with obesity and COVID-19: A global perspective on the epidemiology and biological relationships.

In recent decades, the prevalence of obesity in children has increased dramatically. This worldwide epidemic has important consequences, including psychiatric, psychological and psychosocial disorders in childhood and increased risk of developing non-communicable diseases (NCDs) later in life. Treatment of obesity is difficult and children with excess weight are likely to become adults with obesity. These trends have led member states of the World Health Organization (WHO) to endorse a target of no increase in obesity in childhood by 2025. Estimates of overweight in children aged under 5 years are available jointly from the United Nations Children’s Fund (UNICEF), WHO and the World Bank. The Institute for Health Metrics and Evaluation (IHME) has published country-level estimates of obesity in children aged 2–4 years. For children aged 5–19 years, obesity estimates are available from the NCD Risk Factor Collaboration. The global prevalence of overweight in children aged 5 years or under has increased modestly, but with heterogeneous trends in low and middle-income regions, while the prevalence of obesity in children aged 2–4 years has increased moderately. In 1975, obesity in children aged 5–19 years was relatively rare, but was much more common in 2016. It is recognised that the key drivers of this epidemic form an obesogenic environment, which includes changing food systems and reduced physical activity. Although cost-effective interventions such as WHO ‘best buys’ have been identified, political will and implementation have so far been limited. There is therefore a need to implement effective programmes and policies in multiple sectors to address overnutrition, undernutrition, mobility and physical activity. To be successful, the obesity epidemic must be a political priority, with these issues addressed both locally and globally. Work by governments, civil society, private corporations and other key stakeholders must be coordinated.

The epidemiological burden of obesity in childhood: a worldwide epidemic requiring urgent action

A Global Review of Food-Based Dietary Guidelines.

The 2018 Global Nutrition Report shares insights into the current state of global nutrition, highlighting the unacceptably high burden of malnutrition in the world. It identifies areas where progress has been made in recent years but argues that it is too slow and too inconsistent. It puts forward five critical steps that are needed to speed up progress to end malnutrition in all its forms and argues that, if we act now, it is not too late to achieve this goal. In fact, we have an unprecedented opportunity to do so.

2018 Global Nutrition Report: Shining a light to spur action on nutrition

The Global Nutrition Report calls on governments, businesses and civil society to step up efforts to address malnutrition in all its forms and tackle injustices in food and health systems.

Everyone deserves access to healthy, affordable food and quality nutrition care. This access is hindered by deeper inequities that arise from unjust systems and processes that structure everyday living conditions. This year’s Global Nutrition Report uses the concept of nutrition equity to elucidate these inequities and show how they determine opportunities and barriers to attaining healthy diets and lives, leading to unequal nutrition outcomes. We examine the global burden of malnutrition with an equity lens to develop a fuller understanding of nutrition inequalities. In doing this, we pinpoint and prioritise key actions to amplify our efforts and propel progress towards ending malnutrition in all its forms.

The Global Nutrition Report calls for a pro-equity agenda that mainstreams nutrition into food systems and health systems, supported by strong financing and accountability. With only five years left to meet the 2025 global nutrition targets, time is running out. We must focus action where the need is greatest for maximum impact.
