The aim of this study was to analyze the impact of early life famine exposure to MASLD risk by causally oriented acyclic graph (DAG). Methods: The data of 15,791 subjects with abdominal ultrasound examination in a physical examination center in Chongqing were analyzed. Participants were divided into (born between January 1, 1953 and December 31, 1955), late childhood exposure group (born between January 1, 1956 and December 31, 1958), infant exposure group, fetal exposure group (born between January 1, 1959 and December 31, 1961) and non-exposure group (born between January 1, 1962 and December 31, 1964). The unbiased adjustment set was obtained by the DAG model. The results were adjusted using binary logistic and linear regression models. Results: The prevalence of MASLD in this population was 38.1%. However, men and women have opposite risks of MASLD in people exposed to famine. Compared with the non-exposure group, the risk of MASLD was lower in the male fetal famine exposure group (OR = 0.688, 95%CI: [0.608 to 0.779], P = 0.000) and the infant famine exposure group (OR = 0.673, 95% CI: 0.593 to 0.764, P = 0.000) and late childhood exposure group (OR = 0.628, 95% CI: [0.537 to 0.735], P = 0.000). The risk of MASLD in the late childhood exposure group of female was about 1.2 times higher than that in the non-exposure group (OR = 1.236, 95% CI: [1.089 to 1.404], P = 0.001). Men who experienced famine early in life had lower cardiometabolic risk factors for BMI, triglycerides, and high-density lipoprotein, while women who experienced famine had higher fasting blood glucose. Conclusions: Early exposure to famine may reduce the risk of MASLD in old age in men, but the experience of famine in late childhood may increase the risk of MASLD in old age in women, and the difference in risk between genders may be due to the different effects of famine experience on cardiometabolic risk factors indicators in men and women. The differences between this study and previous studies may be due to the differences in the degree of disaster damage between regions and the different age stages of the study subjects, and further longitudinal studies are needed to explore the trend of MASLD.展开更多
