| 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 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 P-value for linear trend in BMI across categories of a given SES variable
3 Q1 to Q5 refer to the England and Wales general population fifths of Townsend score at LSOA level
