Orange juice intake and anthropometric changes in children and adolescents

Abstract

AbstractObjective:Evaluate associations between orange juice (OJ) consumption and anthropometric parameters.Design:Prospective cohort study assessing the association between OJ intake and changes in BMI and height-for-age Z-score (HAZ) using mixed linear regression.Setting:2004–2008, USA.Participants:Children from the Growing Up Today Study II (n 7301), aged 9–16 years at enrollment.Results:OJ consumption was positively associated with 2-year change in HAZ in girls (mean (se)): 0·03 (0·01) for non-consumers, 0·03 (0·02) for 1–3 glasses/month, 0·06 (0·01) for 1–6 glasses/week and 0·09 (0·02) for ≥1 glass/d after full adjustment (Ptrend = 0·02). However, OJ consumption was not associated with 2-year change in BMI percentile (kg/m2, mean (se)): –0·44 (0·36) for non-consumers, 0·20 (0·41) for 1–3 glasses/month, –0·04 (0·34) for 1–6 glasses/week and –0·77 (0·62) for ≥1 glass/d in girls, Ptrend = 0·81; –0·94 (0·53) for non-consumers, –1·68 (0·52) for 1–3 glasses/month, –0·81 (0·38) for 1–6 glasses per week and –1·12 (0·61) for ≥1 glass/d in boys, Ptrend = 0·49.Conclusion:OJ consumption was favourably associated with height growth but unrelated to excess weight gain. OJ may be a useful alternative to whole fruit in the event that whole fruit intake is insufficient.
