護理師評估社區健康計畫在預防兒童肥胖的成效，哪項結果代表成功？
A nurse is assessing a community health program's effectiveness in preventing childhood obesity. Which outcome indicates success?
- AIncrease in after-school screen time增加放學後的螢幕時間
- BIncrease in children participating in physical education classes✓ 正解增加兒童參與體育課的人數
- CReduction in availability of water fountains in schools減少學校內飲水機的可用性
- DDecrease in local availability of fresh fruits and vegetables減少當地新鮮水果和蔬菜的供應
預防兒童肥胖的社區計畫應致力於營造健康環境。增加兒童參與體育課（Physical education）的比例，直接增加了身體活動量，這對於預防肥胖有顯著效果。相反地，限制新鮮蔬果、增加靜態時間（Screen time）或減少飲水設施，皆會加劇肥胖問題。成功的健康計畫應結合營養教育、環境改善與增加活動機會，全方位改善兒童的健康生活型態。
Community programs to prevent childhood obesity should focus on creating a healthy environment. Increasing children's participation in physical education directly increases physical activity, which has a significant effect on preventing obesity. Conversely, restricting access to fresh fruits and vegetables, increasing screen time, or reducing drinking water facilities will all worsen obesity. A successful health program should combine nutrition education, environmental improvement, and increased opportunities for activity to comprehensively improve children's healthy lifestyles.
