A new study by Australian researchers has established a link between the rollout of high-speed internet services and an increase in obesity rates. The research, conducted by teams from Monash University, the University of Melbourne, and RMIT University, sheds light on how digital connectivity may influence physical activity and eating behaviors.
Analyzing data from the Household, Income, and Labor Dynamics in Australia (HILDA) survey alongside broadband adoption records, researchers observed:
The study attributes the rise in obesity to the sedentary behaviors encouraged by internet usage.
Dr. Klaus Ackermann from Monash University explained that prolonged online engagement lowers metabolic rates and increases snacking habits, resulting in higher calorie intake.
Additionally, access to high-speed internet has made physical errands and in-person social interactions less necessary, further reducing opportunities for physical activity. Activities like binge-watching content and online gaming have also contributed to the trend.
The findings are consistent with global trends. Previous research, including a 2024 study in Türkiye, found a positive correlation between internet usage and higher BMI among university students. A 2019 international review also revealed that heavy internet users had a 47% greater likelihood of being overweight or obese compared to light users.
The researchers emphasize the need for public health initiatives to counter the impact of sedentary lifestyles driven by internet use.
