Abstract: Objective To understand the prevalence of borderline high lipidemia and dyslipidemia and associated factors in adults in Tianjin. Methods According to the national nutrition surveillance protocol, the surveys were conducted among the residents aged 18 years selected from Hexi, Beichen, Jinghai districts in Tianjin in 2010, 2011 and 2012 respectively. Univariate and multivariate non-conditional logistic regression analyses were conducted to identify the factors associated with borderline high lipidemia and dyslipidemia. Results The overall levels of total cholesterol (TC), triglyceride (TG) and high density lipoprotein (HDL-C) levels were 4.86 1.18, 1.47 1.18 and 1.45 0.32 mmol/L respectively. The overall prevalence of dyslipidemia was 27.4%,the overall prevalence of hypercholesterolemia, hypertriglyceridemia and low HDL-C lipidemia were 11.7%, 13.4% and 7.6% respectively, and the overall prevalence of borderline high cholesterolemia and borderline high triglyceridemia were 23.4% and 13.9% respectively. Multivariate logistic regression analysis showed that male, overweight, obesity and sedentariness were independent associated factors for dyslipidemia, but regular exercise, occasional exercise were the protective factors; central obesity, living in suburban area, living rural area, aged, smoking/drinking were the associated factors for borderline high cholesterolemia, while being male was the protective factor; central obesity, obesity, hypertension were the associated factors for borderline high hypertriglyceridemia, while living in suburban area was the protective factors. Conclusion The prevalence of borderline high lipidemia and dyslipidemia has reached a high level in the residents aged 18 years in Tianjin, so it is necessary to conduct targeted comprehensive interventions according to the distributions of borderline highlipidemia andyslipidemia.
