Previous research fails to optimally assess such characteristics and consider sex, age, and maturity among youth. Therefore, the aims were to 1) present the multidimensional health-related characteristics of 9-14-year-olds from the UK, 2) examine sex differences, and 3) account for the effect of age and maturity on such characteristics. Eighty-one girls (mean age = 12.8 ± 1.2 years) and 136 boys (mean age = 13.1 ± 1.2 years) were purposively sampled and assessed across each of the four health-related domains. Multiple ANCOVA analyses examined sex differences among characteristics while accounting for chronological age. Pearson's correlations were used to evaluate the associations between maturity and multidimensional health-related characteristics. Multidimensional health-related characteristics were lower than similar populations and highly variable. Boys outperformed girls on most physical measures (ES = -0.76 to 0.76), elicited greater self-determined motivation (ES = 0.36), greater perceived competence (ES = 0.54), and engaged in more vigorous physical activity (ES = 0.78). Small age effects were present across some characteristics (e.g. isometric mid-thigh pull). Associations between maturity and multidimensional health-related characteristics were different for boys and girls (e.g. maturity offset positively associated with motor competence scores in girls only). Results suggest that multidimensional health-related characteristics of 9- to 14-year-olds are a concern, and are impacted by sex, age, and maturity.
