Obesity, a global health challenge, disproportionately affects individuals across different age groups, amplifying the risk of chronic diseases and reducing quality of life. This article explores the intricate relationship between age and obesity, emphasizing how age-related physiological changes, behavioural patterns, and social determinants contribute to the prevalence and severity of obesity. Drawing on recent studies, we analyse the differential impacts of obesity in childhood, adulthood, and older age, highlighting key findings from epidemiological data and clinical research. The discussion underscores the need for age-specific interventions and policies to combat obesity effectively, fostering healthier lifestyles across the lifespan.

The escalating prevalence of obesity represents a significant public health concern, with its impacts extending beyond physical health to encompass mental and societal dimensions. Age emerges as a critical factor influencing the development and progression of obesity, as it modulates metabolic rates, activity levels, and dietary habits. Childhood obesity, often associated with genetic predispositions and lifestyle factors, lays the groundwork for a lifelong struggle with weight management. In contrast, adult obesity reflects a complex interplay of behavioural choices, environmental factors, and metabolic shifts. Among older adults, obesity presents unique challenges, including sarcopenic obesity, which combines excess adiposity with muscle loss, exacerbating frailty and morbidity. Understanding these age-specific dynamics is essential for designing targeted prevention and treatment strategies to address the obesity epidemic [1].
Obesity arises from a chronic energy imbalance, where caloric intake consistently exceeds expenditure. This imbalance, however, is influenced by age-related physiological changes and lifestyle patterns. During childhood and adolescence, growth spurts and hormonal fluctuations significantly affect body composition. Excess calorie consumption during these formative years often leads to adiposity, setting the stage for obesity in adulthood. Studies indicate that obese children are more likely to remain obese as adults, with long-term health implications including cardiovascular diseases, type 2 diabetes, and certain cancers. In adulthood, metabolic rates naturally decline with age, reducing caloric requirements. Combined with sedentary behaviours and high-calorie diets, this decline contributes to weight gain. Additionally, life events such as pregnancy, career demands, and stress further predispose adults to obesity. Middle-aged adults, in particular, face challenges in weight management due to hormonal shifts like declining estrogen in women and testosterone in men, which promote fat accumulation. In older populations, obesity manifests differently. While some individuals continue to gain weight, others experience weight redistribution, with fat accumulating in the visceral region. Sarcopenic obesity becomes a pressing concern, characterized by a simultaneous loss of muscle mass and strength, compounding the adverse effects of excess weight. This condition is associated with heightened risks of disability, falls, and dependency, complicating the management of obesity in the elderly [2,3].
Recent epidemiological studies underscore the age-specific prevalence of obesity. According to the World Health Organization, global obesity rates have tripled since 1975, with distinct patterns across age groups. Childhood obesity affects approximately 39 million children under the age of five, signalling a critical need for early intervention. Among adults, obesity rates peak during middle age, correlating with increased risks of metabolic syndrome and chronic diseases. In older adults, obesity prevalence declines slightly but remains clinically significant due to its association with reduced mobility and quality of life. Clinical trials reveal that interventions tailored to specific age groups, such as family-based programs for children, workplace wellness initiatives for adults, and strength training for seniors, yield better outcomes in managing obesity [4].
The relationship between age and obesity is multifaceted, shaped by biological, behavioural, and social determinants. Genetic predispositions, hormonal changes, and alterations in body composition contribute to age-related variations in obesity. However, environmental factors such as food availability, socioeconomic status, and cultural attitudes toward body image also play pivotal roles. Behavioural patterns, including dietary choices and physical activity levels, evolve with age, reflecting shifts in priorities and responsibilities. For instance, children and adolescents are more susceptible to the influence of peers and advertising, while adults often struggle with time constraints and stress-related eating. Older adults face barriers such as reduced mobility and limited access to exercise facilities, further complicating weight management. Addressing obesity requires a holistic approach that considers these age-specific challenges. Public health policies should prioritize early prevention by promoting healthy eating and physical activity among children and adolescents. For adults, workplace and community programs can provide support for sustainable lifestyle changes. In older adults, interventions should focus on preserving muscle mass and functionality while managing weight. Multidisciplinary strategies involving healthcare providers, educators, and policymakers are crucial to fostering a culture of health across all age groups [5].
The interplay between age and obesity highlights the importance of adopting age-specific strategies to combat this pervasive health issue. Recognizing the unique challenges faced by individuals at different life stages can inform targeted interventions, improving health outcomes and quality of life. Future research should explore innovative approaches to obesity prevention and management, incorporating technological advancements and personalized medicine. By addressing the complex relationship between age and obesity, we can pave the way for a healthier, more equitable society.
