Association between pulse pressure and body mass index in the Chinese adult population in Jilin Province 2013.

Background: Pulse pressure and body mass index were associated with cardiovascular disease, and the relationship of pulse pressure and body mass index exhibited different situation in different study population. We want to access the association among pulse pressure, body mass index, and other factors in different gender Chinese population in Jilin Province. Methods: A multi-stage stratified random cluster sampling method was used to randomly select 3789 residents who without history of taking hypertension medication for questionnaire surveys, physical examinations and laboratory tests. IBM SPSS version 24.0 was used to perform all analysis, and Chi -square test and multinomial logistic regression were applied to analysis data.Results: For males, the multinomial logistic regression analysis shown that overweight was risk factor for other three pulse pressure groups. Besides, the older people(age≥60 years), and hypertension were risk factors for PP3 and PP4. In females results, aged≥45 years, hypertension and waist circumference was risk factor for three higher pulse pressure groups. Body mass index and pulse pressure was no significant association in three pulse pressure groups, and people with higher education level and above were protective factors in the PP3 and PP4 both in males and females.Conclusion: the relationship between body mass index and pulse pressure in different gender displayed different situation, and the association of waist circumference and pulse pressure was stronger than the relationship between body mass index and pulse pressure for women.
