研究目的：通過橫斷面調查廣東省六間幼稚園幼兒體能活動、身體活動能力及熒 屏時間，探討幼兒體能活動、身體活動能力及熒屏時間的特點及可能影響因素。 研究方法：以中山 4 間和肇慶 2 間幼稚園中班（K2）的 57 名幼童為研究對象， 調查了為期一週的在校體能活動。實地測量了幼童的七項體質指標及 Movement-ABC 測試，以自編問卷調查的形式調查幼童及其家長之看電視時間和 電子產品的使用時間。 研究結果: 中山幼童在校體育活動量多於肇慶幼童，中山城市走平衡木、雙腳連 續跳優於肇慶，男童小球擲遠好於女童，反映小肌肉群活動能力的指標相對不敏 感。中山幼童及家長看電視時間少於肇慶，使用電子產品時間少於多餘肇慶，男 童使用電子產品時間長於女童。城市和性別是影響幼童熒屏時間的主要因素，在 校體育活動及身體活動能力對看電視時間、電子產品使用和熒屏時間影響不大。 研究結論：不同發展水準的城市，幼稚園兒童在校體能活動量、大肌肉群的身體 活動能力和熒屏時間有所不同。家長看電視和使用電子產品的多寡，對子女熒屏 時間有一定影響。
