A representative sample of 671 school-age young graduated from high school in 2013, 550 and 548 of them took the PSU for LSA and MSA, respectively. Only school-age young with high (n=91) and low (n=69) SA in both tests were considered. A total of 122 school-age children agreed to participate in the study and were divided as follows: Group 1: high PSU outcome (n= 70; males n= 48) and Group 2: low PSU outcome (n=52; males n= 23). Data were analysed by means of SAS software. Independently of gender, DHA, socio-economic status and head circumference-for-age Z-score were the most relevant parameters explaining both LSA (R2= 0.650; p < 0.0001) and MSA outcomes (R2=0.700; p < 0.0001). These results can be useful for nutriti...
