Abstract

OBJECTIVE

The aim of this study was to- conduct a meta-analysis of the association of bone mineral density, height, and weight in different populations between vegans and non-vegans.

METHODS

Based on a search of PubMed, Web of Science, MEDLINE, the Cochrane Library, the Wanfang database, and the CNKI database, 14 relevant publications were collected by two researchers. Review Manager 5.3 and Stata 12.0 software were used for data analysis.

RESULTS

The following results were observed in this study: 1) the density of lumbar vertebrae was higher in vegans than in non-vegans (mean difference: -0.05, 95% CI: -0.09 to -0.01, = 0.01); 2) hip bone density was higher in non-vegans than in vegans (mean difference: -0.08, 95% CI: -0.14 to -0.02, = 0.008); 3) weight was higher in non-vegans than in vegans (mean difference: -2.21, 95% CI: -4.05 to -0.37, = 0.02); and 4) height was higher in non-vegans than in vegans (mean difference: -1.87, 95% CI: -2.52 to -1.22, < 0.00001).

CONCLUSION

Our study suggests that a vegetarian lifestyle may contribute to bone loss, low height, and low weight based on existing evidence.

摘要

目的

本研究旨在对纯素食者和非纯素食者不同人群中骨密度、身高和体重之间的关联进行荟萃分析。

方法

通过检索PubMed、科学网、MEDLINE、考克兰图书馆、万方数据库和中国知网数据库，两名研究人员收集了14篇相关出版物。使用Review Manager 5.3和Stata 12.0软件进行数据分析。

结果

本研究观察到以下结果：1）纯素食者的腰椎密度高于非纯素食者（平均差异：-0.05，95%置信区间：-0.09至-0.01，P = 0.01）；2）非纯素食者的髋骨密度高于纯素食者（平均差异：-0.08，95%置信区间：-0.14至-0.02，P = 0.008）；3）非纯素食者的体重高于纯素食者（平均差异：-2.21，95%置信区间：-4.05至-0.37，P = 0.02）；4）非纯素食者的身高高于纯素食者（平均差异：-1.87，95%置信区间：-2.52至-1.22，P < 0.00001）。
