Effect of community‐based participatory nutrition promotion (CPNP) programme on the prevalences of stunting, underweight, and wasting at 12‐months follow‐up (visit5) in Habro and Melka Bello districts, Ethiopia (2012‐2014)
| Control area | Intervention area | Absolute percentage (%) difference (95% CI)† | P‐value | |||
|---|---|---|---|---|---|---|
| n * | n (%) | n * | n (%) | |||
| Stunting (LAZ < −2) | ||||||
| Enrollment | 620 | 119 (19.2) | 614 | 123 (20.0) | ||
| 12‐month follow‐up | 612 | 300 (49.0) | 513 | 214 (41.7) | −8.1 (−15.1, −1.1) | 0.02 |
| Wasting (WLZ < −2) | ||||||
| Enrollment | 614 | 104 (16.9) | 611 | 102 (16.7) | ||
| 12‐month follow‐up | 611 | 611 (31.8) | 429 | 429 (29.8) | 3.2 (−3.3, 9.6) | 0.34 |
| Underweight (WAZ < −2) | ||||||
| Enrollment | 735 | 141 (19.2) | 713 | 137 (19.2) | ||
| 12‐month follow‐up | 624 | 256 (41.0) | 501 | 168 (33.5) | −6.3 (−12.6, −0.1) | 0.046 |
At enrollment, the total number of children surveyed was 1790 (n = 914 in control and n = 876 in intervention areas), no length measurement (n = 14), no weight measurement (n = 6), removed outliers (n = 10 for LAZ > 6 or < −6, n = 10 for WLZ > 5 or < −5) and treated as missing values through data cleaning process (n = 532 for length, n = 336 for weight); at 12‐month follow‐up, the total number of children surveyed was 1395 (n = 711 in control and n = 684 in intervention area), no length measurement (n = 2), no weight measurement (n = 1), removed outliers (n = 10 for LAZ > 6 or < −6, n = 27 for WLZ > 5 or < −5) and treated as missing values through data cleaning process (n = 258 for length, n = 269 for weight).
Estimated by mixed effect linear regression analysis, adjusting for enrollment status in growth outcomes, child age and sex, father's education, household wealth status, household food security, type of nearest health facilities, mobile phone availability, district location and data collectors who surveyed the households.
