Objectives: To investigate the relationship between asymptomatic target organ damage (TOD) and different somatotypes in a community-dwelling old Chinese. Methods: 2098 Chinese old residents (age ≥ 65 years old) from the northern Shanghai were recruited. Body mass index (BMI) and other somatotype parameters were recorded\. Asymptomatic TOD, including urine albumin/creatinine, estimated glomerular filtration rate (eGFR), carotid intima-media thickness (IMT), left ventricular mass index (LVMI), left ventricular diastolic function (LVDD), and carotid-femoral pulse wave velocity (PWV) was measured by the MyLab30 Gold CV system (ESAOTE SPA, Genoa, Italy) and SphygmoCor (AtCor Medical, Sydney, Australia). Results: Of all 2098 residents, 817 (38.9%) were overweight, 289 (13.8%) were obese. After adjusted for age and male gender, LVH, LVDD, artery stiffness, carotid arterial plaque, and microalbuminuria were significantly and independently associated with obesity and overweight (p < 0.001). Whereas, LVH were negatively associated with underweight (p = 0.01). In Receiver operating characteristic analysis, when taking participants without any TOD as a health condition, the optimal BMI was 23.5 kg/m2. Conclusion: Asymptomatic TOD was significantly associated with overweight and obesity in the elderly Chinese, especially in women. Whereas the underweight may favor in the prevention of LVH.
