Correlation between lipid accumulation product and type 2 diabetes mellitus among middle-aged and elderly people in China
Objective To explore the correlation between lipid accumulation product(LAP)and the risk of type 2 diabetes mellitus(T2DM)among middle-aged and elderly people,and provide the scientific basis for prevention and treatment of T2DM.Data were from the China Health and Retirement Longitudinal Study(CHARLS)2011 and 2015,5 317 residents(≥45 years old)meeting the inclusion and exclusion criteria were selected as the subjects.The investigation was performed with questionnaire,physical examination and lab test.According to LAP(male)=[WC(cm)-65]×TG(mmol/L)and LAP(female)=[WC(cm)-58]×TG(mmol/L),the LAP of subjects were calculated.The t test and x2 test were used to analyze the data,the used software was SPSS 20.0;R 4.2.3 software was utilized for restrictive cubic spline(RCS)function to analyze the non-linear relationship between LAP and risk of T2DM.Multivariate logistic regression was used to analyze the correlation between LAP and risk of T2DM.Results At the follow-up survey in 2015,492 subjects(9.3%)were diagnosed with T2DM.RCS analysis showed that there was the non-linear correlation between LAP and the risk of T2DM,when all LAP was>25.553,male LAP was>19.055 and male LAP was>31.127,the risk of T2DM increased significantly.Multivariate logistic regression showed that after adjusting for the confounding factors,as compared with the lower LAP group(≤ 25.553),the T2DM risk of higher LAP group(>25.553)increased by 145%(OR=2.45,95%CI:1.97-3.05)in all people;as compared with male lower LAP group(≤19.055),the T2DM risk of male higher LAP group(>19.055)increased by 71%(OR=1.71,95%CI:1.25-2.34);as compared with female lower LAP group(≤31.127),the T2DM risk of female higher LAP group(>31.127)increased by 217%(OR=3.17,95%CI:2.31-4.35).Conclusion LAP has some indicating role of T2DM risk among middle-aged and elderly people,LAP may be included in monitoring index system for early T2DM risk among middle-aged and elderly people.
