Effective interventions for guiding children to change behaviours are needed to tackle obesity. We evaluated the effectiveness of the 'Planning Health in School' programme (PHS-pro) on children's nutritional status. A non-randomised control group pretest-posttest trial was conducted at elementary schools of a sub-urban municipality in Porto's metropolitan area (Portugal). A total of 504 children of grade-6, aged 10-14, were assigned in two groups: children of one school as the intervention group (IG), and three schools as the control group (CG). Anthropometric measures included height, weight, waist circumference (WC), BMI and waist-to-height ratio (WHtR), and lifestyle behaviours (self-reported questionnaire) were assessed at baseline and after PHS-pro. IG children grew significantly taller more than CG ones ( < 0.001). WC had reduced significantly in IG (-0.4 cm) whereas in the CG had increased (+0.3 cm; = 0.015), and WHtR of IG showed a significant reduction ( = 0.002) compared with CG. After PHS-pro, IG children consumed significantly fewer soft drinks ( = 0.043) and ate more fruit and vegetables daily than CG. Physical activity time increased significantly in IG ( = 0.022), while CG maintained the same activity level. The PHS-pro did improve anthropometric outcomes effectively leading to better nutritional status and appears to be promising in reducing overweight and obesity.
需要有效的干预措施来引导儿童改变行为，以解决肥胖问题。我们评估了“学校健康计划”（PHS-pro）对儿童营养状况的有效性。在波尔图大都市区一个郊区市镇的小学进行了非随机对照预-后试验。共有 504 名 10-14 岁的六年级儿童被分为两组：一所学校的儿童为干预组（IG），三所学校为对照组（CG）。在基线和 PHS-pro 后评估了身高、体重、腰围（WC）、BMI 和腰高比（WHtR）等人体测量指标以及生活方式行为（自我报告问卷）。IG 儿童的身高增长明显高于 CG 儿童（<0.001）。IG 的 WC 显著减少（-0.4 厘米），而 CG 的 WC 则增加（+0.3 厘米；=0.015），IG 的 WHtR 与 CG 相比显著降低（=0.002）。PHS-pro 后，IG 儿童每天饮用的软饮料明显减少（=0.043），水果和蔬菜的摄入量增加。IG 儿童的体育活动时间显著增加（=0.022），而 CG 则保持相同的活动水平。PHS-pro 有效地改善了人体测量结果，导致更好的营养状况，并且似乎有望减少超重和肥胖。
