一項新的大型研究為日益激烈的全國性辯論火上澆油，這場辯論的焦點在於，持續接觸智慧型手機會對美國人，尤其是兒童造成怎樣的影響。

《兒科學》雜誌對超過1萬名青少年進行的分析發現，過早擁有智慧型手機與憂鬱症、肥胖症和慢性睡眠問題的風險顯著升高相關，而且孩子獲得第一部智慧型手機的年齡越小，長期後果似乎就越嚴重。

青少年大腦認知發展研究的研究人員追蹤了10588名參與者，比較了擁有智慧型手機的12歲青少年和沒有智慧型手機的12歲青少年之間的健康狀況。

結果令人震驚。

擁有智慧型手機的兒童罹患憂鬱症的風險高出31%，肥胖風險高出40%，睡眠不足的可能性高出62%。

隨著兒童接觸智慧型手機的時間越來越早，這種趨勢也愈發明顯。

兒童每提早一歲擁有智慧型手機，肥胖風險就會增加9%，睡眠不足的風險也會增加8%。

研究還發現，12歲時沒有智慧型手機，但第二年就擁有智慧型手機的兒童，其健康狀況會顯著惡化，包括出現臨床等級精神病理學症狀的幾率高出57%，睡眠問題增加50%，即使研究人員控制了基線心理和行為健康狀況後，這一結果依然成立。

這種擔憂遠不止於青少年時期。

如今，成年人平均每天使用智慧型手機的時間超過四個小時，研究人員指出，這會對健康產生一系列連鎖反應：睡眠紊亂、焦慮加劇、姿勢相關的慢性疼痛、與久坐使用手機相關的代謝功能障礙，以及整體健康狀況的顯著下降。

另一個重新受到關注的領域是長期輻射暴露。

智慧型手機會發射射頻電磁場，國際癌症研究機構已將其列為可能對人類致癌的物質。

研究表明，兒童吸收的輻射量明顯高於成人；發表在《環境研究》雜誌上的研究發現，發育中的大腦吸收的輻射量是成人的兩到三倍，兒童的骨髓吸收的輻射量大約是成人的10倍。

Researchers Warn Early Smartphone Use Linked to Rising Depression, Obesity, and Sleep Disorders

A new major study is adding fuel to a growing national debate over what constant smartphone exposure is doing to Americans, especially children.

The Pediatrics analysis of more than 10,000 adolescents found that early smartphone ownership correlates with sharply higher risks of depression, obesity, and chronic sleep problems, and the younger kids receive their first device, the worse the long-term outcomes appear.

Researchers with the Adolescent Brain Cognitive Development Study tracked 10,588 participants, comparing health trajectories between 12-year-olds who owned smartphones and those who did not.

The results were stark.

Children with smartphones showed a 31 percent higher risk of depression, a 40 percent increase in obesity risk, and a 62 percent higher likelihood of inadequate sleep.

The trend deepened with earlier exposure.

For every year younger a child acquired a smartphone, obesity risk rose by another 9 percent, and inadequate sleep rose by 8 percent.

The study also found that children who did not own smartphones at age 12 but received one the following year had dramatically worse outcomes, including 57 percent higher odds of clinical-level psychopathology and a 50 percent jump in sleep problems, even after researchers controlled for baseline mental and behavioral health.

Concerns extend well beyond adolescence.

Adults now spend more than four hours per day on smartphones on average, and researchers point to cascading health effects: disrupted sleep, increased anxiety, posture-related chronic pain, metabolic dysfunction tied to sedentary phone use, and measurable declines in overall well-being.

Another area drawing renewed scrutiny is long-term radiation exposure.

Smartphones emit radiofrequency electromagnetic fields, which the International Agency for Research on Cancer has classified as possibly carcinogenic to humans.

Studies show children absorb significantly more radiation than adults; research published in Environmental Research found that developing brains absorb two to three times more and that children’s bone marrow absorbs roughly 10 times the local dose of adults.
