Effect of a Multiple-Micronutrient-Fortified Fruit Powder Beverage on the Nutrition Status, Physical Fitness, and Cognitive Performance of Schoolchildren in the Philippines
This study aim ed to determine the effect of a multiple-micronutrient-fortified beverage on the micronutrient status , physical fitness , and cognitive performance of schoolchildren . The study was a r and omized , double-blind , placebo-controlled trial of schoolchildren assigned to receive either the fortified or nonfortified beverage with or without anthelmintic therapy .  Data on hemoglobin level , urinary iodine excretion ( UIE ) level , physical fitness , and cognitive performance were collected at baseline and at 16 weeks post-intervention . The fortified beverage significantly improved iron status among the subjects that had hemoglobin levels < 11 g/dl at baseline . The proportion of children who remained moderately to severely anemic was significantly lower among those given the fortified beverage . In the groups that received the fortified product , the median UIE level increased , whereas among those who received the placebo beverage , the median UIE level was reduced significantly . Iron- and /or iodine-deficient subjects who received the fortified beverage showed significant improvements in fitness ( post-exercise reduction of heart rate ) and cognitive performance ( nonverbal mental ability score ) . The study showed that consumption of a multiple-micronutrient-fortified beverage for 16 weeks had significant effects on iron status , iodine status , physical fitness , and cognitive performance among iron- and /or iodine-deficient Filipino schoolchildren .  Anthelmintic therapy improved iron status of anemic children and iodine status of the iron-adequate children at baseline but it had no effect on physical fitness and cognitive performance . The results from the clinical study showed that a multiple-micronutrient-fortified beverage could play an important role in preventing and controlling micronutrient deficiencies
