Obesity prevention across the lifespan: assessing the efficacy of intervention studies and discussing future challenges.

Abstract

Obesity is intricately linked with metabolic conditions that disrupt hormones and metabolism, often resulting in weight-related challenges. Given the heightened mortality rates associated with cardiovascular and metabolic disorders linked to obesity, there is a pressing call to mobilize medical professionals, researchers, and policymakers towards advocating for healthy lifestyles and preventing obesity. Traditionally, obesity prevention and treatment have been viewed as separate endeavors, with prevention primarily falling under public health initiatives and treatment within the purview of clinicians. However, this division has led to significant healthcare costs without a substantial reduction in obesity rates. Our search encompassed published articles focused on prevention, excluding any mention of "treatment". Data was gathered from diverse sources including academic databases, government health agency websites like the CDC, research organizations, clinical trials registries, and public health campaigns. Due to the diverse range of interventions (encompassing dietary modifications, physical activity promotion, policy initiatives, education, and community-based programs, either independently or in combination), and the variability in study design and population demographics, we conducted a narrative review to systematically present and critically analyze evidence on preventing overweight and obesity across different age groups. Effectively addressing obesity prevention necessitates a comprehensive, multidisciplinary approach that establishes an environment where healthier choices are accessible and viable for all. This requires collaborative efforts between individuals, communities, healthcare providers, policymakers, and industries to institute enduring change. Furthermore, there remains a critical need for national and international guidelines tailored to age-related risk factors, paving the way for innovative precision medicine approaches centered on salutogenesis rather than pathogenesis.
