鋅 Zinc × 兒童急性腹瀉
結論：證據支持但有警示
兒童急性腹瀉是鋅補充劑證據最強的適應症之一：WHO 自 2004 年起與 UNICEF 共同將鋅列為唯一與 ORS 併用的標準輔助治療，並收錄於 WHO 兒童基本藥物清單；2024 年 WHO 委託 JOGH 系統性回顧（38 篇 RCT、33,693 名兒童）及 2016 年 Cochrane Lazzerini 回顧一致顯示能縮短病程約 13 小時、降低嚴重度，縮短病程與嚴重度有 GRADE moderate 支持；2024 JOGH WHO 委託 MA 對腹瀉死亡率未見顯著效益（RR 0.

雖然 Examine 僅給 Grade C（單一研究 n=100），但這是 Examine 全表覆蓋偏成人/西方文獻所造成的取樣不足，並非真實證據強度的反映；以 L2/L4e/L5e 三方權威建議與 MA 數量、樣本規模綜合判斷，應評為 A 級。
主要保留為嘔吐副作用增加（RR 1.46）與在高所得國家效益較不一致。

Oral zinc for treating diarrhoea in children (Cochrane Review, Lazzerini M & Wanzira H)
結論：In children >6 months, zinc shortened acute diarrhoea by ~half a day (MD -11.46 h, 95% CI -19.72 to -3.19; 9 trials) and reduced diarrhoea persisting to day 7 (RR 0.73, 95% CI 0.61-0.88), with the largest effect in malnourished children (MD -26.39 h, high certainty); but it had NO effect in children <6 months (MD +5.23 h, 95% CI -4.00 to 14.45, NS) and increased vomiting (RR 1.57, 95% CI 1.32-1.86).
前往 PubMed Zinc supplementation for acute and persistent watery diarrhoea in children: A systematic review and meta-analysis (WHO-commissioned)
結論：Across 38 RCTs, zinc increased recovery from acute diarrhoea (RR 1.07, 95% CI 1.03-1.10) and reduced duration (MD -13.27 h, 95% CI -17.66 to -8.89; moderate certainty) and improved persistent-diarrhoea recovery (RR 1.75, 95% CI 1.34-2.30; low certainty), but increased vomiting (RR 1.46, 95% CI 1.22-1.76), which was lower with low-dose vs high-dose zinc (RR 0.80).
前往 PubMed Zinc supplementation for treating diarrhea in children: a systematic review and meta-analysis (PAHO/Pan American Journal)
結論：Across 18 RCTs (n=7,314), zinc reduced diarrhoea duration by ~20 hours (MD -20.12 h, 95% CI -29.15 to -11.09, I2=91%), with a markedly greater effect in malnourished children (MD -33.17 h, 95% CI -33.55 to -27.79, I2=0%); vomiting incidence was significantly higher with zinc.
前往 PubMed Zinc supplementation in acute diarrhea (Zou TT et al., Indian J Pediatr; DARE quality-assessed)
結論：Pooling 8 RCTs, zinc significantly reduced acute diarrhoea duration (WMD -14.47 h, 95% CI -25.06 to -3.89; P=0.007), but with significant unresolved heterogeneity that subgroup/sensitivity analyses could not eliminate.
前往 PubMed Effect of Zinc Supplementation in Children with Acute Diarrhea: Randomized Double Blind Controlled Trial (Trivedi SS et al., India)
結論：In 117 children (zinc n=60 / placebo n=57), stool-frequency reduction from day 1 to days 3-5 was 62% with zinc vs 26% with placebo (36% absolute between-group difference, reported as highly statistically significant) plus a 45% greater reduction in stool output and shorter hospital stay; abstract gives no exact p-value or CI.

台灣媽媽社群普遍認為腸胃炎/腹瀉後補鋅有助於修復腸黏膜，多由小兒科醫師建議或自行查資料後嘗試；同時普遍提醒不要長期亂補、最好先驗血並由醫師開立。

破解迷思 社群最常見的 5 個誤解
✓
事實以為小孩只要常感冒、食慾差就是缺鋅，自己買來補就好
✓
事實把鋅當成單純『提升免疫力』保健品長期天天吃
✓
事實以為腹瀉時補鋅可以取代電解水/口服補液
✓
事實覺得越甜的兒童鋅越好餵，沒注意過甜反而會引發嘔吐
✓
事實誤以為從綜合維他命就能補到足量的鋅
🩹 社群通報的副作用
- 口感過甜引起反胃、想吐
- 空腹吃會胃不舒服
- 長期過量擔心鋅中毒（影響銅吸收）
