Social media plays a fundamental role in shaping eating habits, especially among young people, since their use through digital platforms has transformed the way they access information about nutrition, recipes, diets, and healthy lifestyles. Constant exposure to visual content and messages related to food directly influences daily decisions about what, how, and when to eat. The study aimed to establish the relationship of social media with eating habits in university students from a private university in the city of Huancayo, located in the Junín region of Peru. The research was basic under a quantitative approach with a cross-sectional section, the population was made up of 311 university students enrolled in the 2025-I academic period. The results were processed through structural equations using the Jamovi program. These results indicate a high degree of relationship between the study variables, given that the Spearman Rho correlation coefficient was 0.832 and 0.000 as the significance level, demonstrating a strong, positive relationship. The study concluded that there was a strong, significant relationship between the dimensions of the social media use variable (network use, platform type, social interaction, and personal and social impact) and eating habits.

The COVID-19 pandemic generated significant social transformations in different sectors of society, one of the most important being the labor market. This research establishes the relationship between these transformations and employment trends among repowered item vendors in the city of Huancayo, Peru. Three key dimensions were addressed: destruction, expansion, and modification of employment. The research adopted a quantitative approach, with an exploratory, descriptive, and correlational design. Validated questionnaires were administered to a representative sample of 331 repowered item vendors. The results indicate a significant relationship between social transformation and employment trends, which is reflected in a reconfiguration of employment in this sector. A loss of job opportunities was evident; however, an expansion of employment was also observed through adaptation to new forms of marketing and the growing demand for repowered products. Likewise, changes in labor dynamics were identified, including the use of new sales strategies and the digitization of processes. In conclusion, the pandemic not only negatively affected employment in this sector, but also encouraged resilience and adaptation strategies.
