Associations Of Body Mass Index And Waist-to-height Ratio With Cardiovascular And Cerebrovascular Diseases

Cardiovascular and cerebrovascular diseases,a general name for cardiovascular and cerebrovascular diseases,are an important clinical and public health problem.A more accurate assessment for the risk of these diseases is a prerequisite for preventing high-risk individuals at early stage and solving the burden of these diseases.Studies have shown that waist height ratio is a more effective risk factor for assessing risk of cardiovascular and cerebrovascular diseases than BMI.Objective:The aims of this study were to compare and verify the effects of BMI and WHR on cardiovascular and cerebrovascular diseases in the general population of Shuncheng,Fusun,Liaoning,China.It provided a theoretical basis for preventing and controlling of cardiovascular and cerebrovascular diseases and for further research.Method:The data of this study were obtained from a cross-sectional survey for population health in Shuncheng,Fushun,Liaoning,in 2013 and in 2016.Individuals were excluded if 1)they had long-term use of aspirin or statins for lowering lipid;2)they did not test height,weight,and waist circumference or there corresponding data were missing,3)they did not remember when they had cardiovascular and cerebrovascular diseases;4)they had missing data on sex and age.Body height,weight and waist circumference are directly measured;the history of cardiovascular and cerebrovascular diseases included myocardial infarction,angina,other cardiovascular diseases,cerebral hemorrhage,cerebral thrombosis and other cerebrovascular diseases.The history of cardiovascular and cerebrovascular diseases was confirmed by a structured questionnaire in which whether the corresponding diseases had been diagnosed by medical services centers or hospitals above community level.The Associations of BMI and WHR with cardiovascular and cerebrovascular diseases were analyzed by univariate and multivariate logistic regression models;the covariates included age,sex,history of hypertension,smoking,drinking,and history of diabetes.Two sided P<0.05 was considered statistically significant.Results:1.This study included a total of 3857 individuals,with an average age of 48.4 years.Men accounted for 49.5%;individuals with a history of hypertension accounted for 63.9%;smokers accounted for 24.0%;individuals who drank alcohol accounted for 26.7%;individuals with a history of diabetes accounted for 4.1%.2.Higher age,being sex of female,history of hypertension and history of diabetes mellitus were risk factors for cardiovascular and cerebrovascular diseases(P <0.001);smoking is not a statistically significant factor related to cardiovascular and cerebrovascular diseases(P=0.097);alcohol is not a statistically significant factor related to cardiovascular and cerebrovascular diseases(P=0.964).3.There was a positive statistical correlation between BMI and cardiovascular and cerebrovascular diseases(P=0.048);there was no statistical correlation between waist height ratio and cardiovascular and cerebrovascular diseases(P=0.964);After adjusting for covariates,BMI and waist-to-height ratio were not statistically associated with a single type of cardiovascular and cerebrovascular disease(including coronary heart disease,other cardiovascular diseases,and cerebrovascular disease).Conclusion:1.Higher age,being sex of female,history of hypertension and history of diabetes mellitus were risk factors for cardiovascular and cerebrovascular diseases.2.After adjusting for covariates,elevated BMI was a risk factor for cardiovascular and cerebrovascular diseases,and WHR was not significantly associated with cardiovascular and cerebrovascular diseases.3.Maybe the effects of BMI is more pronounced for cardiovascular and cerebrovascular diseases than WHR.
