A new study led by Australia's Curtin University indicates that young adults who play video games for more than 10 hours per week may experience effects on their diet, sleep patterns, and body weight. Published in the journal Nutrition, the research surveyed 317 university students across Australia, identifying correlations between extensive gaming and certain health indicators.
Study Overview
The study was conducted by researchers at Australia's Curtin University and involved 317 university students from five Australian institutions, with a median age of 20 years. The findings were published in the journal Nutrition under the title "Video Gaming Linked to Unhealthy Diet, Poor Sleep Quality and Lower Physical Activity Levels in Australian University Students."
Participants were categorized into three groups based on their self-reported weekly gaming hours:
- Low Gamers: 0-5 hours per week
- Moderate Gamers: 5-10 hours per week
- High Gamers: More than 10 hours per week
Key Findings
Researchers observed that low and moderate gamers reported comparable health outcomes. However, health outcomes were noted to shift among those who engaged in gaming for more than 10 hours per week. Professor Mario Siervo from the Curtin School of Population Health stated that the findings suggest excessive gaming, rather than gaming itself, was the primary area of concern, with differences emerging beyond the 10-hour weekly gaming threshold.
Diet Quality and Body Weight
- Students gaming over 10 hours weekly exhibited poorer diet quality and a higher median body mass index (BMI).
- High gamers had a median BMI of 26.3 kg/m2. In contrast, low gamers had a median BMI of 22.2 kg/m2, and moderate gamers had 22.8 kg/m2.
- The study indicated that each additional hour of weekly gaming correlated with a reduction in diet quality, even after accounting for factors such as stress and physical activity.
Sleep Quality
- All surveyed groups reported generally poor sleep quality.
- Increased gaming hours were associated with greater sleep disruption, with moderate and high gamers reporting poorer sleep than low gamers.
Implications and Recommendations
Professor Siervo clarified that the study establishes a pattern linking extensive gaming to health risk factors, but does not prove causation. Researchers suggest that moderate gaming appears to be acceptable for most students.
The study indicates that concerns arise when extended gaming sessions may replace essential healthy routines, such as balanced eating, adequate sleep, and physical activity. Given that habits formed during university often persist into adulthood, the researchers recommend practices such as:
- Taking breaks from gaming.
- Avoiding late-night gaming sessions.
- Choosing healthier snacks.
- Ensuring adequate physical activity and sleep.
