Objectives To investigate the association between neck circumference ( NC ) and cognitive impairment and interactions between relevant variables to the risk of cognitive impairment. Methods A population‐based survey was conducted among elderly inhabitants aged 60 years and over from a community in Shanghai suburb. Multivariate logistic regression analyses were performed to evaluate associations and log likelihood ratio tests to examine interactions. Results Cognitive impairment was identified in 269 (10.8%) subjects from 2,500 participants. Higher BMI ( OR = 1.55; 95% CI = 1.11–2.16), higher WHR ( OR = 1.44; 95% CI = 1.07–1.95), and higher total cholesterol ( TC ) ( OR = 1.52; 95% CI = 1.09–2.13) were significantly associated with the increased risk of cognitive impairment. Significant interactions were observed between TC and a few other relevant variables, respectively. Conclusions NC was associated with the high risk of cognitive impairment. Additive effects of NC with TC on cognitive impairment were observed.
