[Abstract]:Objective to investigate the relationship between BMI and breast cancer in Chinese women with different menopausal status. Methods Pub Med,EMBASE, Wanfang database, Weipu database and (CNKI), database were searched by computer. From January 2000 to February 2017, the literature on the relationship between (BMI) grouping and breast cancer incidence in Chinese women was collected from January 2000 to February 2017. Stata12.0 was used for Meta analysis. On the basis of the overall effect relationship, linear and nonlinear models were fitted. If no dose-response relationship was found, the truncation effect of different BMI on breast cancer was further discussed. Publication bias was evaluated by Begg's test. Results A total of 103 141 people were included in 8 articles. The RR value of postmenopausal group was 1.10 (95%CI:0.95~1.27), the RR value of postmenopausal group was 1.52 (95%CI:1.31~1.75), and that of premenopausal group was 1.10 (95%CI:0.95~1.27). No dose-response relationship was found after the experiment. = 2.02 P nonlinearity 0.57). Compared with the control group (18. 5 kg/m~2BMI 鈮，
