Diseases and disorders associated with excess body weight

Area of Science:

• Public Health
• Epidemiology
• Preventive Medicine

Background:

• Excess body weight is a global health crisis, particularly prevalent in North America and Europe, often termed an 'epidemic'.
• This condition has steadily increased over recent decades, affecting individuals across all age groups, including children and adolescents.
• Overweight and obesity are associated with a substantially elevated risk of severe health issues, including all-cause mortality, cardiovascular diseases, cancers, type 2 diabetes, hypertension, liver disease, asthma, and psychopathology.

Purpose of the Study:

• To highlight the significant health risks associated with excess body weight.
• To emphasize the multifactorial causes of obesity, primarily excess caloric intake and insufficient energy expenditure.
• To underscore the importance of lifestyle modifications in mitigating these risks.

Main Methods:

• This study is a review of existing literature on the prevalence and consequences of excess body weight.
• It synthesizes data on the associated health risks and etiological factors.
• It evaluates the potential impact of lifestyle interventions.

Main Results:

• Excess body weight is a major risk factor for a wide array of chronic diseases and premature death.
• The primary drivers identified are a positive energy balance resulting from high caloric intake and low physical activity.
• The prevalence of overweight and obesity is alarmingly high in pediatric and adolescent populations.

Conclusions:

• Lifestyle modifications, encompassing dietary changes and increased physical activity, are paramount for combating the excess body weight epidemic.
• Implementing such changes can significantly reduce the incidence of associated diseases and mortality.
• Adopting healthier lifestyles is key to increasing longevity and enhancing overall quality of life.
