Determinants of Body Mass Index and Intelligence Quotient of Elementary School Children in Mountain Area of Nepal: An Explorative Study
Children (Basel, Switzerland)
several studies aimed identify subtypes dyscalculia many studies either predefined groups eg children reading mathematical difficulties vs children isolated mathematical difficulties analyzed regarding cognitive profiles topdown approach clusters children dyscalculia cwd identified based narrow range cognitive mathematical skills datadriven bottomup approach however remained difficult establish robust subtypes dyscalculia across studies background conducted mixture model analysis order explore identify subtypes dyscalculia based broad range variables intelligence reading fluency working memory attention various mathematical skills total sample comprised 174 elementary school cwd iq 70 mathematical abilities percentile rank 10 consisted two subsamples first subsample based diagnostic test focusing calculation hrt 14 n 71 46 girls 25 boys age 928 years sd 094 whereas second subsample based diagnostic test strong focus basic numerical capacities zarekir n 103 78 girls 25 boys age 894 years sd 105 results provided convincing evidence existence two subtypes cwd slightly impaired subtype strongly impaired subtype subtypes differed strongly regarding mathematical abilities analyses suggest differences attention could also key factor therefore comorbid attention difficulties seem relevant factor needs considered establishing subtypes substantial intelligence differences dyscalculia subtypes could found differences working memory reading fluency negligible overall results seemed robust regardless diagnostic test used assessing dyscalculia planning interventions cwd existence subtype substantial attention problems kept mind
