An investigation of brachial-ankle pulse wave velocity among middle-aged residents in Shanghai and Inner Mongolia autonomous region / 中华内科杂志

ABSTRACT

Objective To compare the epidemiological characteristics and differences in brachialankle pulse wave velocity (baPWV)among middle-aged residents between Shanghai and Inner Mongolia autonomous region (Inner Mongolia),and to observe the prevalence of arterial stiffness in the two populations.Methods A total of 922 volunteers aged between 45 and 59 from Shanghai and Inner Mongolia were selected by stratified cluster random sample method.BaPWV was measured and related data were collected.Results A total of 903 cases were enrolled in this study,including 441 from Shanghai and 462 from Inner Mongolia.The baPWV value of middle-aged residents in Inner Mongolia was higher than that in Shanghai [(1 548 ± 281) cm/s and (1 476 ± 254) cm/s,P ＜ 0.001].The abnormal rate of baPWV (baPWV ≥ 1 400 cm/s) in Inner Mongolia was also higher than that in Shanghai [67.5 ％ (312) and 57.4％ (253),P ＜0.001].The baPWV value of middle-aged men in Inner Mongolia was (1 568 ±299) cm/s,while it was (1 508 ± 260) cm/s in Shanghai,no statistical difference was found (P ＞ 0.05).The baPWV value of middle-aged women in Inner Mongolia was (1 534 ± 268) cm/s,which was higher than that of Shanghai [(1 468 ±252)cm/s,P ＜0.01].The abnormal rate of baPWV of middle-aged men in Inner Mongolia and Shanghai was 67.0％ (126/188) and 60.8％ (59/97),respectively (P ＞ 0.05).The abnormal rate of baPWV of middle-aged women in Inner Mongolia and Shanghai was 67.9％ (186/274) and 56.4％(194/344),respectively.Conclusions The difference of baPWV value and abnormal rate of baPWV of middle-aged residents between Inner Mongolia and Shanghai exists.Middle-aged people in Inner Mongolia should be more alert to the incidence of arteriosclerosis and cardio-cerebrovascular diseases.
