Age and Body Composition in HbAA and HbSS Subjectsa
| Subject (n) | Age, years | FFM, kg | FM, kg | Weight, kg | Height, cm | BMI, kg/m2 |
|---|---|---|---|---|---|---|
| HbAA (9) | 9 ± 2 | 29 ± 9 | 6 ± 2 | 35 ± 10 | 139 ± 18 | 18 ± 2 |
| HbSS (12) | 9 ± 2 | 24 ± 6 | 4 ± 2 | 28 ± 7 | 133 ± 12 | 16 ± 1 |
| P | 0.462 | 0.254 | 0.088 | 0.176 | 0.569 | 0.006 |
Values are mean ± SD; P values Mann-Whitney U test.
FFM = fat-free mass, FM = fat mass, BMI = body mass index. BMI was significantly lower for the HbSS (sickle cell disease) group compared with the HbAA (normal) group.
