ABSTRACT

Objective To investigate the prevalence of dyslipidemia in migrants in Inner Mongolia Autonomous Region.Methods A stratified multi-stage cluster equal size sampling was performed among the migrants aged ≥ 18 years who were engaged in manufacturing,wholesale retail,accommodation and catering service,social service,construction and other and 1501 migrants from five area in Inner Mongolia Autonomous Region was investigated by means of questionnaires survey,physical measurements and laboratory detection.Results Complete data was obtained in 1 496 study subjects.The prevalence of dyslipidemia was 42.65％ (638/1496),the age-standardized prevalence was 42.05％;the prevalence of hypercholesterolemia,hypertriglyceridemia,combined hyperlipidemia and low high-density lipoprotein hyperlipidemia were 4.90％ (73/1491),14.76％ (220/1491),4.83％(72/1 496),25.27％ (378/1 496),respectively.Dyslipidemia characterized by high triglyceride (HTG)and low high-density lipoprotein cholesterol (LHDL-C) accounted for 81.97％ (523/638).The prevalence of dyslipidemia and HTG/LHDL-C dyslipidemia were similar,which increased significantly with age in both females and males,but was significantly higher in males.The prevalence among migrants with other occupations was highest.The prevalence of HTG/LHDL-C dyslipidemia didn't significantly increase with the duration of migration.However,the prevalence of high TG and dyslipidemia increased significantly with the duration of migration,the prevalence of high TG in age group ＜45 years showed the same characteristics.Conclusions The prevalence of dyslipidemia in migrants in Inner Mongolia was high,and the main form was HTG/LHDL-C dyslipidemia.The prevalence in males,the middle aged and aged as well as those with other occupations were high.Migrants with longer duration of migration had higher prevalence of dyslipidemia.
