Excessive screen time combined with unhealthy
snacking may significantly increase the risk of
metabolic syndrome in teenagers, according to a
large nationwide study. Metabolic syndrome is a
cluster of conditions including high blood pressure,
elevated blood sugar, excess abdominal fat, and
abnormal cholesterol or triglyceride levels that
increase the risk of heart disease, stroke, and type
2 diabetes. The study, conducted as part of Brazil's
Study on Cardiovascular Risks in Adolescents
(ERICA), analyzed data from 33,900 adolescents aged
12–17 years. Researchers assessed waist
circumference, blood pressure, blood glucose, HDL
cholesterol, and triglyceride levels to evaluate
metabolic health.
The findings revealed that 85%
of teenagers regularly consumed snacks while
watching television, while 64% snacked during
computer use or video gaming. Importantly, there was
no significant association between screen time and
metabolic syndrome among adolescents who did not
snack while using screens. However, among those who
habitually ate snacks during screen time, the risk
of metabolic syndrome increased as the duration of
screen exposure became longer.
These findings
suggest that reducing unhealthy snacking during
screen time may be as important as limiting screen
time itself. Encouraging healthier eating habits and
promoting active lifestyles may help reduce the
growing burden of metabolic disorders among
adolescents. |
