Population
Most studies included cancer patients with mixed diagnoses groups, except for four studies that included specifically patients with acute lymphoblastic leukemia [27, 29, 32, 34] and one that included only children with leukemia and brain tumours [31]. Moreover, the majority of studies had few inclusion criteria, with the exception of two studies that were designed specifically for CCS with obesity, defined as a body mass index (BMI) ≥ 85th percentile [29, 33] and one for survivors who reported symptoms of fatigue and had not engaged in PA in the previous 6 months [26].
Eight studies targeted the cancer patients or survivors [21-24, 26, 28, 30, 31], five were family-oriented [25, 27, 29, 32, 34] and one was designed for parents [33].
Participants in nine studies were survivors [21-24, 26, 28, 29, 31, 33], whereas the remaining five studies recruited children undergoing treatment [25, 27, 30, 32, 34].
Nine studies were conducted in the USA [22-24, 27, 29, 31-34] , two in Hong Kong [26, 30], one in Canada [21], one in the Netherlands [25] and one in Taiwan[28].
