Multivariable regression models for prevalence of acute malnutrition diagnosed by MUACZ and MUAC
| Survey-level analysis of prevalence | MUAC for Age | MUAC | ||
|---|---|---|---|---|
| Prevalence MUACZ < − 2 | Prevalence MUAC < 125 | |||
| Variable | Estimate (95% CI) | p-value | Estimate (95% CI) | p-value |
| Acute malnutrition (WHZ < − 2) prevalence | 0.84 (0.78–0.90) | < 0.0001 | 0.47 (0.43–0.50) | < 0.0001 |
| Stunting (HAZ < -2) prevalence | 0.23 (0.20–0.25) | < 0.0001 | 0.14 (0.12–0.15) | < 0.0001 |
| Two-category age ratio (6–23 v. 24–59 months) | −0.29 (− 4.11–3.52) | 0.8796 | 7.15 (4.70–9.60) | < 0.0001 |
| Sex Ratio (Male to Female) | 1.50 (− 3.28–6.28) | 0.5389 | 0.56 (− 2.51–3.63) | 0.7206 |
| Adjusted Model R2 | 0.4968 | 0.4277 | ||
| Acute malnutrition (WHZ < − 2) prevalence | 0.70 (0.63–0.76) | < 0.0001 | 0.36 (0.32–0.40) | < 0.0001 |
| Unadjusted Model R2 | 0.3314 | 0.2444 | ||
