Evans AM, et al. - Authors gauged the implicated factors (viz foot arches, foot strength, joint mobility, vitamin D, iron) in children with leg pain compared to a control group. For the first time, they defined the leg pain sub-groups—growing pains (GP), restless legs (RLS), both (mixed). Findings suggestd the presence of hypovitaminosis D in 87% of the sample, and anaemia in 13%. The predictors for leg pain were: an increased strength of ankle dorsiflexors and joint flexibility. An association of increased body weight, waist girth, and BMI with leg pain was noted.
