Obesity: A Global Health Challenge and Pathways to Prevention

Estimated reading time: 8 minutes

Definition

The health risks associated with being overweight or obese have been recognized by medical professionals for over two millennia. The World Health Organization (WHO) defines obesity as “excess or abnormal fat accumulation that presents a risk to health”. Similarly, the Centers for Disease Control and Prevention (CDC) describes overweight and obesity as “weight that is considered higher than what is considered healthy for a given height is described as overweight or obesity”.

The diagnosis of overweight and obesity is made by measuring people’s weight and height and by calculating the body mass index (BMI): weight (kg)/height² (m²). Although BMI (Body Mass Index) is not a perfect measure, it is widely used by both WHO and CDC to classify these conditions: a BMI between 25 and 29.9 kg/m² is considered overweight, while a BMI of 30 kg/m² or higher is classified as obesity. Regardless of the definition, obesity is a chronic disease affecting adults, adolescents, and children worldwide, and is now recognized as a global epidemic.

Global Statistics and Trends

According to information from WHO, over recent decades, the prevalence of overweight and obesity has reached unprecedented levels globally. As of 2022, around 2.5 billion adults were overweight, with over 890 million classified as obese equating to roughly 43% of the global adult population, up from 25% in 1990. Regional disparities exist, with an overweight prevalence of 31% in regions like South-East Asia and Africa, compared to 67% in the Americas.

Children and adolescents are also significantly impacted, with an estimated 37 million children under five classified as overweight in 2022. In Africa, the number of overweight children under five has increased by nearly 23% since 2000, and nearly half of all overweight young children are in Asia. The global obesity prevalence among adults has doubled since 1990, with approximately 16% of adults classified as obese in 2022.

Causes of Overweight and Obesity

The factors contributing to overweight and obesity are complex and multifaceted:

1. Lifestyle Factors: Sedentary behaviors and high-calorie diets, particularly those high in processed, energy-dense foods, are significant contributors to obesity. Urbanization and industrialization have led to reduced physical activity and increased caloric intake (Hruby & Hu, 2015).
2. Genetic and Environmental Interactions: Genetic predisposition plays a significant role, especially when combined with environmental factors like high-fat diets and limited physical activity, heightening the likelihood of weight gain (Astrup et al., 1997; Jebb, 2004).
3. Economic and Societal Shifts: Economic growth and globalization have increased the availability of inexpensive, calorie-dense foods, making it easier for people worldwide to exceed their caloric needs (Ford, Patel, & Narayan, 2017).
4. Psychosocial Factors and Stress: Chronic stress and social influences, such as food marketing and easy access to fast food, encourage unhealthy eating behaviors (Cahnman, 1968).
5. Low-Grade Chronic Inflammation: Obesity creates a state of low-grade inflammation, which worsens metabolic health and reinforces a cycle of weight gain (Saltiel & Olefsky, 2017).

Consequences of Obesity

1. Physical Health Risks: Obesity is a key risk factor for type 2 diabetes, cardiovascular disease, hypertension, and certain cancers, such as breast and colorectal cancers, all of which can reduce life expectancy and increase morbidity (Lawrence & Kopelman, 2004; Head, 2015).
2. Metabolic and Endocrine Disorders: Obesity can cause insulin resistance, dyslipidemia, and metabolic syndrome, increasing the risk of type 2 diabetes and other metabolic diseases (Pi‐Sunyer, 1993; Hruby et al., 2016).
3. Psychological and Social Impact: Obesity often results in low self-esteem, depression, and social stigma, all of which can reduce quality of life. Behavioral therapy may alleviate these issues but remains underutilized (Chu et al., 2019).
4. Sleep and Respiratory Issues: Excess weight around the airway can lead to sleep apnea and other respiratory problems, disrupting sleep and impacting overall health (Reilly et al., 2003).
5. Economic Burden: Obesity-related health costs are significant, affecting both individuals and society through healthcare expenses and productivity losses (Finkelstein et al., 2005; Runge, 2007).

Preventing and Managing Obesity

1. Lifestyle Interventions: Low-calorie diets and regular exercise are central to managing weight and improving health markers. Structured programs focusing on dietary changes and physical activity are effective, especially with behavioral support (Galani & Schneider, 2007; Dyson, 2010).
2. Behavioral Approaches: Behavioral therapy helps individuals adopt sustainable lifestyle changes through techniques like goal-setting and self-monitoring. Programs such as the Diabetes Prevention Program and Look AHEAD have shown promising results in weight loss and health improvements, though maintaining these changes long-term is challenging (Johnston et al., 2007).
3. Medical Management: Medications can support weight loss when lifestyle interventions alone are insufficient, typically recommended for individuals with a BMI over 30 or obesity-related health conditions (Yumuk et al., 2015).
4. Surgical Interventions: Bariatric surgery can be an effective option for those with severe obesity who have not succeeded with other treatments, offering long-term weight loss and improvements in metabolic health (La Sala & Pontiroli, 2020; Lean, 2009).
5. Early Childhood Prevention: Instilling healthy eating habits, promoting physical activity, and limiting screen time from a young age are critical to preventing obesity in children, with family and community involvement playing a crucial role (Dabas & Seth, 2018).
