[Influencing factors for remnant cholesterol among residents aged 20 and above in China, 2015-2017].

Objective: To analyze the remnant cholesterol level and its influencing factors among Chinese residents aged 20 years old and older.

Methods: Data were collected from the Chinese Nutrition and Health Surveillance(2015-2017). A stratified, multi-stage, random sampling method was used. A total of 135934 residents 20 years of age and older from 31 provinces were included in this study. Remnant cholesterol level was estimated using the internationally estimation method. By the National Bureau of Statistics provided by the sixth census data weighted adjustment, analysis the crowd RC level and its influencing factors.

Results: The following factors were associated with high RC level: overweight(OR=1.624, 95%CI 1.508-1.748) or obesity(OR=2.208, 95%CI 1.984-2.458); married(OR=1.347, 95%CI 1.135-1.598) or other(OR=1.433, 95%CI 1.138-1.805); living in rural area(OR=1.588, 95%CI 1.475-1.708); smoking(OR=1.435, 95% CI 1.300 1.584); excessive drinking(OR=1.110, 95%CI 1.014-1.215); long sedentary time(OR=1.020, 95%CI 1.006-1.035); hypertension(OR=1.435, 95%CI 1.335-1.541); diabetes(OR=1.853, 95%CI 1.645-2.088) or dyslipidemia(OR=7.663, 95%CI 7.097-8.273). The following factors were associated with low RC level: high income group(OR=0.878, 95%CI 0.803-0.959; OR=0.796, 95%CI 0.723-0.877); family history of CHD(OR=0.765, 95%CI 0.765-0.960).

Conclusion: This study found that residual cholesterol levels in Chinese residents aged 20 and above are closely related to various factors, especially in the population with dyslipidemia and obesity.
