Note. Statistics: n = simple absolute frequency, % = simple percentage, ∑% = cumulative percentage. Coefficients of association: η = eta and p = right-tailed probability value for ANOVA’s F-statistic, with homogeneity of variance among six groups (with n > 10) tested by Levene’s test; r_S = Spearman’s rank-order correlation, and p = two-tailed probability value. Sample size: N = 416. * Down syndrome is a chromosomal condition (the presence of all or part of a third copy of chromosome 21) that is not classified as a chronic disease, but patients are referred to the chronic disease care unit when they have cardiac, digestive or metabolic disorders associated with this syndrome.
