HUBUNGAN KONSUMSI SUSU DAN KALSIUM DENGAN DENSITAS TULANG DAN TINGGI BADAN REMAJA
<p class="MsoNormal"><strong><span style="font-size: 10pt;" lang="en-us" xml:lang="en-us"> </span></strong><span style="font-size: 10pt;">The objective of this study was to analyze the relationship between milk and calcium intake with body height and bone density of adolescent. The study applied a cross sectional design to 246 senior high school students in Bogor. The subject aged 16-17 years old were selected purposively. Milk and calsium intake was derived from the food intake data collected by applying a semi-FFQ method for a week. Bone density (stiffness index) was measured by densitometer of achilles insight. The results of the study showed that the mean intake of milk was 170.7±136.3 ml/day with average frequency 6 times/week, and mean intake of calcium was 250.0±212.6 mg/day with contribution of milk was 44.0%. The mean stiffness index of subjects was 97.5±18.3; and the mean stiffness index of boys (104.4±18.9) </span><span style="font-size: 10pt;" lang="en-us" xml:lang="en-us">wa</span><span style="font-size: 10pt;">s significantly higher than girls (92.9±16.3). The calcium intake of milk and calcium intake of calsium-rich foods of non milk </span><span style="font-size: 10pt;" lang="en-us" xml:lang="en-us">wa</span><span style="font-size: 10pt;">s not correlated with the bone density and body height; but milk intake, frequency and length of milk intake </span><span style="font-size: 10pt;" lang="en-us" xml:lang="en-us">were</span><span style="font-size: 10pt;"> correlated with body height and bone density. This implies the important of milk intake in bone density and linear growth of adolescent.</span></p>
