To evaluate the causal effect of childhood BMI on LC susceptibility, a two-sample Mendelian randomization (MR) study was performed.<h4>Methods</h4>The two-sample MR analysis utilized 25 single nucleotide polymorphisms (SNPs) as instrumental variables for childhood BMI. Genetic summary data from the International Lung Cancer Consortium and FinnGen databases were analyzed to estimate the causal effect of these SNPs on LC susceptibility. The IVW method was employed as the primary analysis, supplemented by the Weighted Median, MR-Egger, and MR pleiotropy residual sum and outlier test.<h4>Results</hCancer medicineGenetically predicted childhood body mass index and lung cancer susceptibility: A two-sample Mendelian randomization study.PMC1052397282102968ZYGD18021Huang YLiu LWang TZheng QWu DZhou JfalseGenetically predicted childhood body mass index and lung cancer susceptibility: A two-sample Mendelian randomization study.<h4>Background</h4>The association between adult body mass index (BMI) and lung cancer (LC) susceptibility have been reported, but the causal relationship with childhood BMI remains largely unclear.
