Table 2.
Between-group differences (intervention versus control) in mean change of nutrition knowledge, attitude, behavior scores and anthropometric measures of school-aged children (n = 183).
| Intervention (n = 102) | Control (n = 81) | p-Value 1 | |
|---|---|---|---|
| Mean Change ± SE | |||
| Knowledge Attitude Behavior (KAB) scores 2 | |||
| Knowledge scores | 2.25 ± 0.22 | 0.89 ± 0.24 | 0.002 |
| Attitude scores | 0.97 ± 0.17 | 0.82 ± 0.19 | 0.294 |
| Behavior scores | 0.36 ± 0.72 | 0.43 ± 0.96 | 0.521 |
| Anthropometric measurements | |||
| BMI for Age Z-score (BAZ) | 0.10 ± 0.06 | −0.10 ± 0.08 | 0.039 |
| Waist to Height ratio (WHtR) | −0.01 ± 0.008 | −0.02 ± 0.008 | 0.260 |
| Height for age Z-score (HAZ) | 0.39 ± 0.04 | 0.24 ± 0.05 | 0.024 |
| Weight for age Z-score (WAZ) 3 | 0.32 ± 0.12 | 0.08 ± 0.18 | 0.177 |
1 Differences in mean changes (follow up minus baseline) of KAB scores and anthropometric measures between intervention and control groups were conducted using clustered independent tests. Statistical significance was determined at p-value < 0.05. 2 The total knowledge, behavior and attitude scores ranged: 0–15 points, 0–10 points and 0–22 points, respectively. 3 Weight for age z-scores were assessed only for children ≤10 years old (n = 68) as per the WHO growth charts [51].
