BACKGROUND: An effective approach to lifestyle-related factors could be a main treatment for hypertensives. The components of blood pressure (BP) have been reported to have different clinical implications; however, the relationship between various lifestyle-related factors and BP components has not been thoroughly studied in hospital-based general medicine.
METHODS: This relationship was cross-sectionally investigated in a population of outpatients with hypertension but free of other diseases (136 subjects, aged 30 to 75, mean 54.2 years) . A self-administered questionnaire, which included items related to demographics, smoking, alcohol use, affinity for salt, habitual exercise, and sleep status, was used.
RESULTS: After controlling for lifestyle-related factors, multiple regression analysis revealed that body mass index (BMI) and smoking were significantly and positively correlated with systolic BP (SBP) and pulse pressure (PP) . For diastolic BP (DBP), age had a significantly negative, and lack of sleep had a significantly positive, correlation. BMI was also significantly and positively correlated with mean BP (MBP) .
CONCLUSIONS: Our results suggest that lifestyle-related factors are associated with differing BP components. Weight control should receive more attention in SBP, MBP and PP control, anti-smoking in SBP and PP control, and sleep management in DBP control.
