Table III.
Odds ratios (ORs) for a score in the range of “very large” impact of facial and truncal acne in HRQoL (per CDLQI and DLQI) in adjusted logistic regression models with age, sex, acne location, and severity as explanatory variables
| Explanatory variables | CDLQI score >12 |
DLQI score >10 |
||
|---|---|---|---|---|
| Adjusted OR (95% CI) | P value | Adjusted OR (95% CI) | P value | |
| Acne on both the face and trunk (F+T vs F) | 1.86 (1.10 to 3.14) | .028 | 1.61 (1.02 to 2.54) | .042 |
| Female vs male | 1.07 (0.72 to 1.60) | .672 | 0.93 (0.49 to 1.73) | .766 |
| Family history of acne: Yes | 1.93 (0.94 to 3.97) | .067 | 1.21 (0.78 to 1.89) | .317 |
| Urban vs rural residence | 2.06 (0.96 to 4.42) | .058 | 1.84 (1.02 to 3.33) | .046 |
| Unit increase in acne severity on face | 2.31 (1.26 to 4.24) | .017 | 2.25 (1.93 to 2.64) | .001 |
| Unit increase in acne severity on chest | 1.99 (1.32 to 3.02) | .008 | 2.20 (1.14 to 4.22) | .027 |
| Unit increase in acne severity on back | 2.40 (1.15 to 5.00) | .028 | 2.11 (1.62 to 2.75) | .001 |
Country was also included in the adjusted analyses. Acne severities at each body site were not included together in the same model because of collinearity.
CDLQI, Children's dermatology life quality index; CI, confidence interval; DLQI, dermatology life quality index; F, facial acne only; F+T, combined facial and truncal acne; OR, odds ratio.
