Table 4 Association of SES indicators with BMI

From: Mammographic density and markers of socioeconomic status: a cross-sectional study

SES Variable   Ratio1 (95% CI) P-value2
Townsend score Q53 (affluent) 1  
(n = 487) Q4 1.01 (0.97, 1.05)  
  Q3 1.04 (0.99, 1.08) Pt = 0.001
  Q2 1.07 (1.01, 1.12)  
  Q1 (deprived) 1.08 (1.02, 1.15)  
Highest educational level Higher 1  
(n = 369) Further 1.03 (0.98, 1.08) Pt = 0.15
  None/GCSE 1.03 (0.99, 1.07)  
Urban/Rural indicator Rural (≥10,000) 1 Pt = 0.26
(n = 487) Urban (<10,000) 1.03 (0.98, 1.08)  
  1. 1 Ratios (and 95% confidence intervals) of geometric mean BMI for each category of SES measure relative to baseline (highest SES category), adjusted for age at mammography
  2. 2 P-value for linear trend in BMI across categories of a given SES variable
  3. 3 Q1 to Q5 refer to the England and Wales general population fifths of Townsend score at LSOA level
