Pada anak usia sekolah, pertumbuhan linier ditentukan berdasarkan kriteria kurva pertumbuhan WHO/2007 dan CDC/2000 serta persentase tinggi badan menurut Waterlow/1977. Perbedaan kriteria yang digunakan akan menimbulkan perbedaan prevalens perawakan pendek. Penentuan kejar tumbuh anak juga masih mengalami perdebatan karena parameter kejar tumbuh dapat dinilai secara relatif (height-age z-score) dan absolut (height-age-differences). Kejar tumbuh linier yang terutama terjadi dalam 1000 hari pertama kehidupan dinilai dapat terus terjadi hingga usia sekolah. Studi potong lintang dilakukan pada 302 anak usia sekolah di Jakarta Barat. Semua anak diukur tinggi badan sewaktu penelitian dan saat subyek berusia 7 tahun. Perawakan pendek ditentukan dengan menggunakan kriteria WHO/2007, CDC/2000, dan persentase Waterlow/1977. Setiap kelompok usia diukur perbedaan nilai height-age z-score (HAZ) dan height-age-differences (HAD) dalam dua waktu pengukuran yang berbeda untuk melihat kejar tumbuh. Prevalens perawakan pendek pada anak usia sekolah berdasarkan kriteria WHO/2007 adalah 8,55%, berdasarkan CDC/2000 sebesar 13,75%, dan berdasarkan Waterlow/1977 sebesar 7,80%. Nilai Kappa WHO/2007 dan CDC/2000 adalah 0,5, WHO/2007 dan Waterlow/1977 adalah 0,8, sedangkan CDC/2000 dan Waterlow/1977 adalah 0,7. Nilai HAZ anak perempuan adalah -1,78 SD dan anak lelaki -1,44 SD. Nilai HAD anak perempuan adalah -10,83 cm untuk anak lelaki adalah -8,83 cm. Kesesuaian perawakan pendek anak WHO/2007 dan CDC/2000 memberikan hasil yang sama sebanyak 50%, WHO/2007 dan Waterlow/1977 memberikan hasil yang sama sebanyak 80%, sedangkan CDC/2000 dan Waterlow/1977 memberikan hasil yang sama sebanyak 70%. Kesan terdapat kejar tumbuh pada anak usia sekolah di Jakarta Barat berdasarkan adanya perbaikan nilai HAZ dan HAD pada pengukuran kedua dibandingkan dengan pengukuran pertama.
Linear growth in school children is determined by using WHO/2007 and CDC/2000 growth chart, also height-age persentage as Waterlow/1977 criteria. Those classification resulted in different prevalence of short stature. Linear catch-up growth is considered to continue beyond the first thousand days of life, at least until school age. It could be relatively (height-age z score) or absolutely (height-age difference) assessed. A cross-sectional study was conducted in 302 school age children in West Jakarta. Body height was measured at 7 years old and at the time of study. Short stature was defined by using WHO/2007, CDC/2000, and height-age persentage as Waterlow/1977 criteria. Height-age z score (HAZ) and height age differences (HAD) was measured in each group to assess catch-up growth. The prevalence of short stature in school children was 8.55%, 13.75%, and 7.80%, according to WHO/2007, CDC/2000, and height-age persentage as Waterlow/1977 criteria, respectively. Kappa values were 0.5, 0.8, and 0.7, between WHO/2007-CDC/2000, WHO/2007-Waterlow/1977, and CDC/2000-Waterlow/1977, respectively. HAZ was -1.78 and -1.44 SD in female and male subjects, respectively. HAD was -10.83 and -8.83 cm in female and male subjects, respectively. WHO/2007 and Waterlow/1977 has the highest agreement, while WHO/2007 and CDC/2007 has the lowest agreement. Linear catch-up growth was observed among our subjects as determined by HAZ and HAD improvement compared to the first measurement. |
