Abstract

BACKGROUND

N-3 polyunsaturated fatty acids (LCPUFA-ω3), particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) might have beneficial effects on lean mass and fat mass synthesis.

OBJECTIVE

To investigate the effect of LCPUFA-ω3 supplementation on body composition changes in children with acute lymphoblastic leukemia (ALL) at remission and three months (3 mo) after supplementation.

METHODS

This randomized controlled trial enrolled 72 children (3-13 y) with newly diagnosed ALL (placebo group [500 mg sunflower oil]: 36 patients; LCPUFA-ω3 group [225 mg DHA, 45 mg EPA]: 36 patients). LCPUFA-ω3 was administered at 0.100 g/kg of body weight/day for 3 mo. Both groups were provided with an oral milkshake supplement.

MAIN OUTCOMES AND MEASURES

Body composition was measured at diagnosis, remission, and 3 months after supplementation by dual-energy X-ray absorptiometry (DXA). Red blood cell fatty acid analyses were performed with gas chromatography. Student's t test compared the percentage changes in body weight, total body fat percentage (TBFP), and lean body mass (LBM) between the groups. The Mann-Whitney U test was used to compare the groups, and the Friedman range test and Wilcoxon signed rank test were used for intratreatment comparisons. Spearman correlation coefficients were calculated for LBM and erythrocyte LCPUFA-ω3 content.

RESULTS

LBM decreased significantly in both groups. This loss was greater in the placebo group than in the LCPUFA-ω3 group at remission…

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 72 participants or records.
