ABSTRACT=<p><bold>Objectives:</bold> This study aimed to examine the association between early life famine exposure and adulthood cardiovascular diseases (CVDs) risk.</p><p><bold>Methods:</bold> A total of 5,504 subjects were selected using their birthdate from national baseline data of the China Health and Retirement Longitudinal Survey to analyze the association between famine exposure in early life and CVDs risk in adulthood. CVDs was defined based on the self-reported doctor’s diagnosis.</p><p><bold>Results:</bold> The prevalence of CVDs in the unexposed group, fetal-exposed, infant-exposed, and preschool-exposed groups was 15.0%, 18.0%, 21.0%, and 18.3%, respectively. Compared with the unexposed group, fetal-exposed, infant-exposed and preschool-exposed groups had higher CVDs risk in adulthood (<italic>p</italic> &lt; 0.05). Compared with the age-matched control group, infancy exposed to famine had a significantly higher adulthood CVDs risk (OR = 1.52, 95% CI: 1.15, 2.01; <italic>p</italic> = 0.006). The association seems to be stronger among population with higher education level (<italic>P</italic><sub>interaction</sub> = 0.043). Sensitivity analysis revealed consistent association between early-life famine exposure and adult CVDs risk.</p><p><bold>Conclusion:</bold> Early life exposed to the China great famine may elevate the risk of CVDs in adulthood.</p>
