"六歲孩童有心臟病的徵兆"

一項新研究顯示，長時間待在螢幕前的孩童出現危險的徵兆。

最近一份令人震驚的研究顯示，長時間待在電視或電腦前的六歲孩童，可能出現心臟病的初期警訊。雪梨大學的研究人員發現，大部分休閒時間都在坐在螢幕前面的幼童，在眼睛後方的動脈比較狹窄－這是未來心臟衰竭的一項重要指標。

超過1,400名六、七歲孩童在這項研究中接受測試，科學家發現，運動量最高的孩童，平均擁有2.2微米（1微米=0.001毫米）的視網膜動脈，比那些不運動的孩童要粗。

領導這項研究的高皮納斯博士談到這個結果：「這顯示不健康的生活因素會在早期影響微循環，增加日後心血管疾病和高血壓的風險。」

他繼續補充道：「每天用一小時的運動，取代待在螢幕前面的時間，這麼一來可以緩衝孩童視網膜微血管因為久坐造成的影響……應該推廣自由玩耍，學校也要一週強制兩小時的時間給小孩做體育活動。」

(Health) Six-Year-Old Children Show Signs of Heart Disease

A new study shows that children who spend too much time in front of screens display the at-risk signals.

A shocking recent study has shown that 6-year-old children who spend long hours in front of the television or computer can display early warning signs of heart disease. Researchers from the University of Sydney found that young children who sit in front of screens for most of their leisure time have narrower arteries in the back of the eyes - an important indicator of future heart failure.

Over 1,400 6- and 7-year olds were tested in the study, and scientists discovered that the children who did the most physical exercise had, on average, retinal arteries that were 2.2 microns (1 micron = 0.001 of a millimeter) wider than those in the children who did the least exercise.

Dr. Bamini Gopinath, who led the research team, said of the results that this suggests that unhealthy lifestyle factors may influence microcirculation early in life and increase the risk of cardiovascular disease and hypertension later in life.

He went on to add: Replacing one hour a day of screen time with physical activity could be effective in buffering the effects of sedentariness on the retinal microvasculature in childrenKFree play should be promoted and schools should have a mandatory two hours a week in physical activity for children.
