Relationship between zinc content of 24-hour dietary recall and mean serum zinc level.
|Zinc content of meal||Mean serum zinc concentration g/dL (± SD)||-value|
|Genotype AA||Sickle cell anaemia|
|Steady state||Painful crisis |
|Low||45.0||30.7 (12.1)||33.9 (20.7)||.8|
|Moderate||41.1 (17.2)||40.8 (14.0)||24.8 (10.5)||18.4||.000|
|High||43.3 (12.5)||37.6 (13.7)||28.5 (11.4)||9.9||.000|
|Only one subject in the control group had low zinc item and was removed from the statistical analysis; therefore, student -test was used to compare the mean zinc level between sickle cell anaemia subjects in steady state and painful crisis in the first row.|
