Digital Environments and Obesity: The Role of Social Media, Marketing, and Sedentary Behaviors View PDF

The intersection of digital environments and obesity has garnered increasing attention, particularly concerning how social media, marketing strategies, and sedentary behaviors influence health outcomes [1-6]. The current literature underscores a complex web of interactions where digital platforms serve both as tools for health promotion and as vectors for behaviors that may contribute to obesity [7-13].

One prominent theme in the literature is the influence of digital food imagery on eating behaviors. Andersen et al. [14] explores how the viewing, creating, and sharing of digital food photography can shape consumer eating patterns. Their review emphasizes that while food imagery is pervasive, its impact is nuanced; it does not solely exert negative effects but can influence healthy or unhealthy eating depending on context and individual engagement. This suggests that digital food photography acts as a double-edged sword, capable of promoting healthy choices or reinforcing obesogenic behaviors. Complementing this, Granheim et al. [15] systematically map the digital food environment, revealing how digital technology alters the traditional food landscape across multiple dimensions such as marketing, availability, and desirability. Their findings indicate that digital platforms expand the reach and influence of food marketing, often promoting high-calorie, nutrient-poor foods, which can contribute to unhealthy dietary patterns associated with obesity. The shift in the food environment due to digitalization underscores the importance of understanding how digital marketing techniques shape consumer choices.

Indeed, digital marketing emerges as a significant factor in influencing dietary behaviors linked to obesity. Ali-Alsaadi et al. [16] investigates how firm-generated content and social media advertising impact fast-food consumption among adults in the UAE, finding a positive relationship between digital marketing engagement and increased fast-food intake. Similarly, Shamim and Islam [17] examine how digital influencer marketing affects consumer trust and impulsive buying, which can extend to food choices. Their work highlights that perceived message and media credibility foster trust in influencers, potentially leading to impulsive consumption of unhealthy foods promoted online. The role of social media in shaping health-related behaviors extends beyond marketing to include goal setting and lifestyle aspirations. Singh and Sharma [18] analyze how obese individuals disclose weight-loss goals on social media, revealing that such online sharing can motivate healthy lifestyle behaviors. This indicates that social media can serve as a platform for positive health behavior reinforcement, although the overall impact depends on the nature of engagement and support networks.

Furthermore, digital interventions aimed at obesity prevention and treatment are gaining traction. Chai et al. [19] review family-based digital interventions for children, emphasizing that virtual delivery can improve accessibility and support healthy lifestyle changes. Similarly, Calcaterra et al. [20] focus on exergames—active video games—as tools to combat sedentarism in children and adolescents with obesity. Their review suggests that digital media, when used appropriately, can promote physical activity and counteract sedentary behaviors, which are critical factors in obesity management. Sedentary behavior, particularly in children and adolescents, is a recurring concern. Calcaterra et al. [20] advocates for integrating exergames into educational and health programs, emphasizing that digital media should supplement, not replace, physical activity. This aligns with broader discussions on how digital environments can either exacerbate or mitigate sedentary lifestyles, depending on their application.

The influence of social media extends into family and parenting contexts. Dessì et al. [21] explore how parenting styles and social media exposure affect children’s dietary patterns, highlighting that parental feeding practices and digital media consumption are intertwined factors influencing obesity risk. These findings suggest that digital environments shape not only individual behaviors, but also familial dynamics related to nutrition and activity. In addition to direct behavioral influences, digital literacy plays a mediating role in online purchase intentions related to food. Kocarslan and Stoycheva [22] demonstrate that higher digital literacy can influence online shopping behaviors, with social media use serving as a mediating factor. This indicates that enhancing digital literacy could be a strategic approach to mitigate the impact of digital marketing on unhealthy food consumption.

The broader implications of digital marketing strategies are also examined through the lens of artificial intelligence and innovative marketing techniques. Ziakis and Vlachopoulou [23] review artificial intelligence applications in digital marketing, emphasizing their potential to optimize marketing strategies, which could include targeted advertising for unhealthy foods. Similarly, Antczak [24] discusses how digital and social media marketing influence consumer buying behavior, including food choices, further reinforcing the role of digital marketing in shaping dietary patterns linked to obesity. Finally, the literature recognizes the dual role of social media in health promotion and risk. Chaput and LeBlanc [25] address the challenges and opportunities of maintaining healthy lifestyle behaviors in the social media era, advocating for strategies that leverage digital platforms to support public health objectives while minimizing risks. This balanced perspective underscores the importance of designing digital environments that promote healthy behaviors and reduce sedentary tendencies.

In summary, the current research illustrates that digital environments significantly influence obesity-related behaviors through multiple pathways. Food marketing and imagery on social media can promote unhealthy eating, while digital interventions and active gaming offer promising avenues for promoting physical activity and healthy lifestyles. The role of social media in shaping family behaviors and the importance of digital literacy further complicate this landscape. As digital platforms continue to evolve, understanding their impact on sedentary behaviors and dietary choices remains crucial for developing effective public health strategies aimed at combating obesity in the digital age.
