ASUPAN KARBOHIDRAT DAN SERAT BERHUBUNGAN DENGAN LEMAK TUBUH REMAJA SMPN 16 JAKARTA
Abstrak: The purpose of the
study is to explore the relationship between nutrient intakes, physical
activity and percentage of body fat in a group of adolescents. This
cross-sectional study was carried out with 62 adolescents aged 13 to 14 years
old; 34 girls (54,8%) and 28 boys (45,2%). Energy, macronutrients and vitamin D
intake were assessed by two non-consecutive-24 hour food recalls. Calcium
intake was assessed by a semi-quantitative food frequency questionnaire
(SQ-FFQ), physical activity was assessed by Physical Activity Level (PAL) 2 x
24 hours and percentage of body fat was measured by bioelectrical impedance
analysis (BIA). BIA measurements were taken at least 2 hours after meals. The
mean age was 13,2 ± 0,4 years. Mean percentage body fat was 22,2 + 5,9 %. In
bivariate analysis, negative correlations were found between calcium intake (p=
0,002), fiber intake (p=0,009), physical activity (p= 0,016) and body fat. In
multivariate analysis, fiber intake showed a negative correlation (β = -8,397,
p = 0,001) and carbohydrate intake (β = 13,053, p = 0,003) showed a positive
correlation with body fat, adjusted by age and sex. In conclusion, carbohydrate
intake has a positive relationship with body fat and fiber intake has a
negative relationship with body fat in adolescents.
