Few efficacious child obesity interventions have been converted into ongoing community programs in the after-school setting. The aim of this study was to evaluate the impact of phase 2 of the Back to Basics cooking club on dietary behaviours and fruit and vegetable variety in a population at risk of obesity at a low income school with > 10% indigenous population.
Baseline and 3-month dietary intake and social cognitive theory (SCT) constructs were collected in 51 children, mean age 9 years, 61% female. McNemar tests were used for comparison of proportions between categorical variables. Cohen's d was used to compare effect sizes across different measures.
Consumption of one or more fruit servings per day significantly increased from 41% to 67% (P = 0.02, d = 0.13) and there was a trend for increasing the weekly variety of fruit and vegetables. The SCT constructs assessed within the current study improved significantly (P < 0.05), with moderate to large effect sizes (d = 0.33-0.78).
This study documents that a previous efficacious healthy lifestyle program can be adapted for use as an obesity prevention program addressing improvements in vegetable and fruit intakes in a low income community with a relatively high indigenous population.
很少有有效的儿童肥胖干预措施能转化为持续开展的校外社区项目。本研究的目的是评估“回归基础烹饪俱乐部”第二阶段对一所低收入学校中肥胖风险人群的饮食行为以及水果和蔬菜种类的影响,该学校原住民人口超过10%。
收集了51名平均年龄9岁、61%为女性的儿童的基线和3个月饮食摄入量以及社会认知理论(SCT)构建指标。采用McNemar检验比较分类变量之间的比例。使用科恩d值比较不同测量方法的效应大小。
每天食用一份或多份水果的比例从41%显著增加到67%(P = 0.02,d = 0.13),并且水果和蔬菜的每周种类有增加的趋势。本研究中评估的SCT构建指标有显著改善(P < 0.05),效应大小为中等至较大(d = 0.33 - 0.78)。
本研究表明,之前一个有效的健康生活方式项目可以进行调整,用作预防肥胖项目,以改善一个原住民人口相对较多的低收入社区的蔬菜和水果摄入量。
