Females had more NSP ever (P < 0.001, χ2 = 16.26), more NSP in the past month (P < 0.001, χ2 = 27.11) and more chronic NSP (P = 0.029, χ2 = 4.75). There were significant gender differences for height and weight and all physical characteristics (P < 0.05) except arm circumference, kinaesthetic integration and the NDI score.
