Table 2 Multivariable Relationships of Temperatures with Blood Pressure (N = 20,773)

From: The association of remotely-sensed outdoor temperature with blood pressure levels in REGARDS: a cross-sectional study of a large, national cohort of African-American and white participants

Temperature-BP models Same-Day Maximum Temperatures (mmHg difference associated with 20°F lower) Weekly Maximum Temperature Variability (mmHg difference associated with a SD higher variability) Same-Day Minimum Temperatures (mmHg difference associated with 20°F lower) Weekly Minimum Temperature Variability (mmHg difference associated with a SD higher variability)
  Maximum temperature - SBP Model Minimum temperature - SBP Model
Basic adjusted model * 1.5 (1.3, 1.8) -- 1.1 (0.8, 1.3) --
Adjusted (with variability)** 1.4 (1.1, 1.6) 0.4 (0.1, 0.6) 0.7 (0.5, 1.0) 0.7 (0.4, 0.9)
Adjusted (with variability and season) # 1.4 (1.1, 1.8) 0.4 (0.1, 0.6) 0.7 (0.4, 1.1) 0.5 (0.2, 0.8)
  Maximum temperature - DBP Model Minimum temperature - DBP Model
Basic adjusted model * 0.7 (0.5, 0.8) -- 0.4 (0.3, 0.6) --
Adjusted (with variability)** 0.7 (0.5, 0.9) 0.0 (-0.2, 0.1) 0.4 (0.2, 0.5) 0.1 (0.0, 0.3)
Adjusted (with variability and season) # 0.5 (0.3, 0.8) -0.1 (-0.2, 0.1) 0.1 (-0.1, 0.4) 0.0 (-0.2, 0.1)
  1. BP = blood pressure; SBP = systolic blood pressure; DBP = diastolic blood pressure; SD = Standard Deviation
  2. * adjusted for sex, region, population density, income, community poverty, education, race, smoking, alcohol, Body Mass Index, hyperlipidemia, diabetes, and age
  3. ** adjusted for sex, region, population density, income, community poverty, education, race, smoking, alcohol, Body Mass Index, hyperlipidemia, diabetes, age, and weekly temperature variability
  4. # adjusted for sex, region, population density, income, community poverty, education, race, smoking, alcohol, Body Mass Index, hyperlipidemia, diabetes, age, weekly temperature variability, and season
  5. Parameter estimates in bold indicate values that are significant at α = 0.05.
