Hubungan tingkat kecukupan zat gizi, lean body mass, dan aktivitas fisik dengan kepadatan tulang pada mahasiswa Universitas Udayana Denpasar
Abstract: Bone formation and
peak bone mass determine with bone density in adulthood related with osteopenia
or osteoporosis. It could be influenced by nutrition intakes, lean body mass,
and physical activity.
Objective: to analyze the correlation between nutritional adequacy, lean
body mass, physical activity and bone mineral density in Udayana University
Economic’s students, Denpasar.
Methods: Cross-sectional study design was done to female students of
Faculty of Economic and Business, Udayana University, Denpasar. Seventy five
subjects were choosen by simple random sampling.
Results: Research subjects were aged 20-25 years old. The mean t-score of
bone mineral density is -0,363 ± 1,057. Research subjects were classified as
low bone density (osteopenia) 26,7% and 73,3% are normal. Intakes of animal
protein (p = 0,042) and lean body mass (p = 0,011) are related with bone
mineral density protein (p = 0,955) but not on intakes of vitamin A (p =
0,249), vitamin C (p = 0,632), vitamin D (p = 0,864), calcium (p = 0,724), iron
(p = 0,768), magnesium (p = 0,689), phosphorus (p = 0,716), and physical
activity (p = 0,254). There were a positive trend on the level of protein,
vitamin A, vitamin C, vitamin D, calcium, iron, magnesium and phosphorus
sufficiency.
Conclusions: Intakes of Animal protein, lean body mass and physical
activity related with bone mineral density but not on protein, vitamin A,
vitamin C, vitamin D, calcium, iron, magnesium, and phosphorus intake.
Keywords: Nutritional intakes,
lean body mass, physical activity, bone mineral density
