KEPADATAN TULANG, AKTIVITAS FISIK DAN KONSUMSI MAKANAN BERHUBUNGAN DENGAN KEJADIAN STUNTING PADA ANAK USIA 6 – 12 TAHUN

2015 
Studi ini bertujuan untuk menganalis is hubungan antara kepadatan tulang, aktivitas fisik, dan konsumsi makanan dengan kejadian stunting. Analisis menggunakan data anak usia 6.0 – 12.9 tahun (n=19 2 ) dari South East Asian Nutrition Survey (SEANUTS) tahun 2011.Kepadatan tulang diukur dengan metoda dual energy X-ray absorptiometry ( DXA), yang dikategorikan menjadi rendah (≤ -2 SD) dan normal (> 2 SD). Aktivitas fisik dikumpulkan dengan menggunakan pedometer. Aktivitas fisik yang dikategorikan menjadi rendah ( 15 , 891 langkah untuk laki-laki dan > 14 , 070 langkah untuk perempuan). Konsumsi makanan dikumpulkan dengan cara 24 hours dietary recall . Konsumsi protein dikategorikan menjadi rendah ( -2 SD). Physical activity (PA) was measured using pedometers. PA wa s categorized into low ( 15 , 891 steps for boys and 14 , 070 steps for girl s ). Dietary data was collected by 24 hours dietary recall. Protein consumption is categorized into low (< 80% RDA) and normal (≥ 80% RDA). L ogistic regression analysis was used to test the association. The results showed that children with low bone density(≤ -2 SD) had a 5.3 times higher risk to be stunted (OR =5.325; 95% CI=1.075 to 26.387 ) than children with normal bone density. Moderate physicial activity was a protective factor for stunting ( OR =0.139; 95% CI=0.037 to 0.521) than children with high physical activity . Children who consumed <80% of RDA of protein had a higher risk of being stunted ( OR =6.448; 95% CI=1.756 to 23.672) than children with protein intake ≥80%.Therefore, next to improving protein intake , attention also is given to physical activity and bone mineral density to prevent stunting and its long-term impact. Keywords: stunting, bone mineral density, physical activity
