BACKGROUND:

The purpose of this research is to understand the complex relationships of the intensity of electronic gaming and the neurocognitive (Reaction Time, IQ, Spatial IQ) and bodily (BMI, Skinfolds, Visual Acuity) components. Of particular interest was stating for the first time the novelty of the ‘Confounding Triad’ of sleep, food (caloric) gaming, and the specific screen type of the gaming interface.

MATERIALS AND METHODS:

A comparative cross-sectional study was carried out on a stratified random sample of 200 male adolescents (ages 13 to 21) from northern India. Participants were stratified into gamers (≥5 hours/week, n = 122) and non-gamers (<5 hours/week, n = 78). The psychomotor speed was measured using a digital Audio-Visual Reaction Timer, IQ was measured using the Stanford-Binet Intelligence Scale, and Spatial Quotient via online standardized battery, while subcutaneous adiposity was measured using Harpenden skinfold calipers. The confounders were measured using the Pittsburgh Sleep Quality Index (PSQI), a 24-hour dietary recall, and Non-Gaming Screen Time (NGST) logs. Mann–Whitney U tests were used for group comparisons, and Generalized Linear Models (GLM) and Analysis of Covariance (ANCOVA) were used to determine independent effects.

RESULTS:

Compared to non-gamers, gamers displayed faster rates across Auditory, Visual, and Aim Reaction Times ( P < 0.001) and better Spatial Quotient ( P = 0.001). The GLM for Visual Reaction Time demonstrated a dose-dependent improvement for hours spent playing games ( β = −2.15, P < 0.001) that was present even when considering the negative effect on performance from poor sleep ( β = +4.35 per unit increase in PSQI, P < 0.001). Gaming status was significant for the ANCOVA for skinfold thickness ( P = 0.035), but dietary caloric intake was the more important variable ( η 2 = 0.19, P < 0.001). No significant difference was found in IQ ( P = 0.36) or in visual acuity.

CONCLUSION:

The findings indicate that regular practice of interactive gaming provides players with better cognitive and psychomotor skills, even when sleep deprivation is considered. With that said, dietary surplus imposes greater metabolic hazards than gaming behaviors. Therefore, health interventions are encouraged not only to regulate gaming hours but to prioritize the teaching of digital hygiene.
