Rujukan Ilmiah Baku
Standar Baku Antropometri
Standar Antropometri Permenkes RI & WHO
Rumus baku dan ambang batas klasifikasi indeks pertumbuhan.
Rumus Matematis Baku Z-Score
Nilai simpangan baku fisik balita terhadap nilai rujukan median tabel WHO:
- Jika Nilai Riil < Median: Z = (Nilai Riil - Median) / (Median - (-1 SD))
- Jika Nilai Riil > Median: Z = (Nilai Riil - Median) / ((+1 SD) - Median)
Aturan Koreksi Posisi Pengukuran (Permenkes RI)
- Usia 0 - 24 Bulan: Standar diukur Telentang (PB). Jika diukur Berdiri → Ditambah +0.7 cm.
- Usia > 24 Bulan: Standar diukur Berdiri (TB). Jika diukur Telentang → Dikurangi -0.7 cm.
Tabel Ambang Batas Klasifikasi Status Gizi & Pertumbuhan:
| Indeks Antropometri | Nilai Ambang Batas (Z-Score) | Kategori Klasifikasi |
|---|---|---|
| PB/U atau TB/U (Stunting) | Z < -3.0 SD | Sangat Pendek / Severely Stunted |
| PB/U atau TB/U (Stunting) | -3.0 SD ≤ Z < -2.0 SD | Pendek / Stunted |
| PB/U atau TB/U (Stunting) | -2.0 SD ≤ Z ≤ +3.0 SD | Normal |
| PB/U atau TB/U (Stunting) | Z > +3.0 SD | Tinggi |
| BB/TB (Status Gizi / Wasting) | Z < -3.0 SD | Gizi Buruk / Severely Wasted |
| BB/TB (Status Gizi / Wasting) | -3.0 SD ≤ Z < -2.0 SD | Gizi Kurang / Wasted |
| BB/TB (Status Gizi / Wasting) | -2.0 SD ≤ Z ≤ +1.0 SD | Gizi Baik / Normal |
| BB/TB (Status Gizi / Wasting) | +1.0 SD < Z ≤ +2.0 SD | Beresiko Gizi Lebih |
| BB/TB (Status Gizi / Wasting) | +2.0 SD < Z ≤ +3.0 SD | Gizi Lebih / Overweight |
| BB/TB (Status Gizi / Wasting) | Z > +3.0 SD | Obesitas |
