ABSTRACT=<sec><title>Background</title><p>Although the evidence was still limited, some studies suggested that childhood malnutrition might affect cardiac function and structure in adulthood. To address the knowledge gap, this study investigated if the Great Chinese Famine exposure during early life had affected left ventricular hypertrophy (LVH).</p></sec><sec><title>Methods</title><p>This research was a cross-sectional study. It included participants who had cardiac ultrasound assessments and were born in Guangdong, China, from 1 October 1952 to 30 September 1964. They were classified according to their exposure period to famine, namely, no exposure, fetal-, early-, mid-, and late childhood. Multivariate logistic regression and subgroup analysis have been conducted to determine the odds ratio (<italic>OR</italic>) and confidence intervals (<italic>CI</italic>s) between famine exposure and LVH.</p></sec><sec><title>Results</title><p>This research included 2,543 participants, 1,612 women, their mean age was 59.07 ± 3.65 years, and 704 participants had LVH. LVH prevalence was 122 (23.6%), 87 (25.1%), 133 (27.3%), 184 (29.2%), and 178 (31.7%), in non-, fetal-, early-, mid-, and late-childhood exposed groups, respectively (<italic>p</italic> = 0.031), while in the non-exposed group, the <italic>OR</italic>s for developing carotid plaque as a result of fetal, early-, mid- to late-childhood exposure were 1.08 (95% <italic>CI</italic>: 0.76, 1.59, <italic>p</italic> = 0.619), 1.24 (95% <italic>CI</italic>: 1.03, 1.79, <italic>p</italic> = 0.031), 1.49 (95% <italic>CI</italic>: 1.10, 2.01, <italic>p</italic> = 0.009), and 1.64 (95% <italic>CI</italic>: 1.25, 2.18, <italic>p</italic> = 0.001), respectively (<italic>p</italic> for trend = 0.003). There was no interactive effect between gender, obesity, or hypertension history with how the famine influenced LVH, as the subgroups analyses demonstrated (all <italic>p</italic> for interaction &gt; 0.05).</p></sec><sec><title>Conclusion</title><p>This research has demonstrated the potential relationship between Great Chinese Famine exposure during childhood and LVH in adults.</p></sec>
