摘要: The association between serum zinc level and overweight/obesity remains controversial. Hence, we performed a meta-analysis to summarize the relationships. A systematic literature search was in PubMed, Web of Science Embase for relevant English articles up April 20, 2018. pooled standardized mean difference (SMD) with 95% confidence interval (CI) calculated random-effect model. For children adults, results showed that significantly lower cases compared controls ([SMD (95% CI): − 1.13 (− 2.03, − 0.23), Z = 2.45, P Z = 0.014; I2 = 97.1%, I2 < 0.001] [SMD − 0.41 (− 0.68, − 0.15), Z = 3.03, Z = 0.002; I2 = 62.9%, I2 = 0.009], respectively). overweight adults not statistically significant − 0.09 (− 0.27, 0.09), Z = 0.97, Z = 0.334; I2 = 0.0%, I2 = 0.411]. In subgroup analyses, obese non-obese observed − 2.14 (− 3.20, − 1.09)], SMD differ case–control studies − 0.49 (− 0.90, − 0.08)]. Our suggested adults. More large observational are required confirm these future research.
