Zinc is an essential #micronutrient and is often provided as a supplement to help children grow and develop their immune system. #Zinc deficiency is widespread in LMICs, posing a significant risk for morbidity, mortality, and stunted height in young #children. We have recently been reviewing some recent literature on #Zinc supplementation and thought we would share this Cochrane systematic review published last year. Written by @Aamer Imdad et al, the review is entitiled: Zinc supplementation for preventing mortality, morbidity, and growth failure in children aged 6 months to 12 years. The review evaluates the impact of zinc supplementation on reducing mortality and morbidity, along with promoting growth among children. This systematic review was an update to one published in 2014. In this update, 96 studies consisting of randomized controlled trials up to February 2022 were included and GRADE was used to assess its evidence quality. Hospitalized children and children with chronic diseases or conditions were excluded from the study and a total of 219,584 children were included in this review. Studies were conducted across 34 primarily low- to middle-income countries, with the majority of participants being children under the age of five. Here are some of the the key takeaways from the published systematic review: 👉 There was little to no difference in reducing all-cause mortality with preventive zinc supplementation compared to no supplementation  👉Preventive zinc supplementation compared to no zinc does not result in mortality due to all-cause diarrhea but may reduce the mortality due to lower respiratory tract infection and malaria 👉Preventative zinc supplementation likely reduces the incidence of all-cause diarrhea but has little to no difference in morbidity due to lower respiratory tract infection 👉Preventative zinc supplement may lead to a small increase in height The review has not confirmed the optimal range of doses, durations, frequencies, or formulations necessary for zinc supplementation to achieve clinically meaningful improvements in mortality, morbidity, or growth outcomes. The authors suggest that this could be the focus of future studies Overall- This systematic review helps summarize the benefits and drawbacks of zinc supplementation and shows that the benefits of preventive zinc supplementation may outweigh the harms in regions where the risk of zinc deficiency is relatively high. There is a lot of detail in this review and for those that missed it when it came out like we did we would encourage that you give it a read! a link to the review 👉 https://lnkd.in/g3VYDJXy by Sheena Y. #nutritionresearch #systematicreview #nutrition #publichealth
