Relationship between the duration of smoking and blood pressure in Han and ethnic minority populations: a cross-sectional study in China.

ABSTRACT:

Background

Evidence for correlation between the cigarette use and blood pressure change remains ambiguous. This study modelled relationship between the duration of smoking and systolic blood pressure in a large national multi-ethnic cross-sectional survey in China.

Methods

Participants were selected through a multi-stage probability sampling procedure from 2012 to 2017. Former or current smokers were included in this study, whose smoking behaviour, blood pressure, and other demographic information were collected and measured through a face-to-face interview. Linear and non-linear relationships between the duration of smoking and systolic blood pressure were analysed and differences of the association between Han and minority populations were specially checked.

Results

A total of 8801 participants were enrolled in this study. Prevalence of hypertension was 41.3 and 77.8% were current smokers. For every additional year of smoking duration, systolic blood pressure raised by 0.325?mmHg (95% CI 0.296 to 0.354?mmHg, P?ConclusionsSmoking is associated with raised systolic blood pressure in Chinese population. This association is notedly stronger in Chinese minority populations.

Project description:AimsTo investigate the prevalence, ethnic differences and associated risk factors for pterygium in Han and Manchu populations aged 40-79 years in Hebei province, China.DesignCross-sectional study, as a part of the China National Health Survey.SettingHebei province, China.ParticipantsA multistage cluster sampling method with urbanisation level-based stratification was used to select participants for this study. A total of 4591 individuals over 40 years were recruited for this study. Inclusive criteria: (1) residents who had been living in Hebei for more than 1?year; (2) Han individuals with both parents being Han, or Manchu individuals with both parents being Manchu; (3) underwent ophthalmic examinations and (4) information in the questionnaire was complete.Main outcome measuresMultiple logistic regression analysis was used to evaluate the association between pterygium prevalence and factors of interest.ResultsA total of 3790 individuals (2351 Hans and 1439 Manchus) met the study criteria, of which 248 were diagnosed with pterygium (6.5%). There was no significant difference between the prevalence rates in Hans (6.2%) and Manchus (7.2%) (p=0.232). Multivariate analysis revealed that the risk factors for grade 2 or higher pterygium were increasing age (p<0.001) and rural residence (OR 1.83; 95% CI 1.11 to 3.02; p=0.018), while the protective factors include gender (female) (OR 0.58; 95%?CI 0.37 to 0.88; p=0.011), cigarette smoking (OR 0.53; 95%?CI 0.34 to 0.83; p=0.005) and myopia (OR 0.50; 95%?CI 0.33 to 0.77; p=0.002). Premature menopause (OR 2.66; 95%?CI 1.05 to 6.72; p=0.038) increased the risk of grade 2 or higher pterygium in females, while higher high-density lipoprotein (HDL) (OR 1.94; 95%?CI 1.08 to 3.47; p=0.027) was a risk factor of grade 2 or higher pterygium in males.ConclusionThe overall prevalence of pterygium in Han and Manchu population in Hebei, China was approximately 6.1%. There were no differences in the prevalence of pterygium between Hans and Manchus, and the race was not a risk factor. This is the first study to report on the positive association between premature menopause and pterygium in females and between higher HDL levels and pterygium in males.
