Factors Influencing Eating Habits of Video Gamers and Professional eSports Gamers in Peru.

eSports and recreational video gaming are expanding in Peru, yet evidence on gamers' dietary habits and correlates is scarce. We aimed to identify factors associated with eating habits among Peruvian video gamers and professional eSports players. Quantitative and cross-sectional study (Peru, 2023). A culturally adapted version of the German Sport University Cologne questionnaire (28 items; Cronbach's α = 0.86) was administered online using non-probability snowball sampling. The primary outcome was eating-habit classification (adequate vs. inadequate) based on the instrument's scoring. Associations with hypothesized correlates (e.g., gaming-related influences, peer interaction, advertising) were assessed with χ2 or Fisher's exact test (α = 0.05). We analyzed 288 respondents (median age 21 years). Overall, 77.8% exhibited inadequate eating habits. Daily water intake was reported by 72%, whereas daily fruit and vegetable consumption was 21% and 32%, respectively. Peer interaction within the gaming environment (p = 0.037) and the perceived influence of video games (p = 0.031) were significantly associated with poorer eating habits. Sitting time, number of meals per day, daily water intake volume, and weekly gaming hours showed no significant association (all p > 0.05). Most Peruvian gamers report suboptimal diets. Social dynamics in the gamer community and gaming-related influences are linked to poorer eating habits, suggesting that nutrition strategies should be embedded in gamer ecosystems (teams, communities, platforms). Longitudinal and interventional studies are warranted to test targeted behavior-change approaches.
