Macronutrient Intake
Body mass index was in the normal range (ie, 18-25) for 74%
of adult thalassemia subjects studied, and weight (1.24.6
kg) and body mass index (0.42.1) did not change significantly
between the baseline and year 1 assessment for the
adults in this study. Estimated average kilocalorie intake was
between 107% and 163% of estimated caloric requirement
based on age, weight, height, and an assumed sedentary lifestyle.
The difference between intake and expenditure was
much greater in younger children compared with adults
(P0.021), but not different between the adolescents and
adults (Table 3). Older children and adolescents with thalassemia
met the acceptable macronutrient distribution range
for fat intake (Table 3; 25% to 35% of kcal as fat), carbohydrate
(45% to 65% of kcal), and protein (10% to 30% of kcal). However,
adults were consuming more kilocalories as fat on average
than is considered acceptable for healthy adult individuals
(38% vs acceptable range, 20% to 35%). Average dietary
fiber intake was far less than recommendations (25 to 38 g),
regardless of age group considered.
