This study aims to analyze associations between lifestyle-related factors and body mass index (BMI) and blood pressure (BP) in middle-aged and older people in Japan. An association analysis using a multilevel model with demographic and lifestyle-related factors as variables and with BMI, systolic blood pressure (SBP), and diastolic blood pressure (DBP) as outcomes was conducted. Among the modifiable lifestyle factors, we found a significant dose-response association for BMI and slower eating (fast: reference; normal: -0.123 kg/m2 and slow: -0.256 kg/m2). Consuming >60 g/d ethanol was significantly associated, before and after adjustment for BMI, with an increase in SBP of 3.109 and 2.893 mm Hg, respectively. These findings suggest that health guidance should focus on factors such as the eating rate and drinking habits.
