The overall impact of interventions targeting multiple behaviours remains largely unexplored.
This study adopted an integrative lifestyle pattern analysis approach to assess the overall effectiveness of an early childhood intervention on change across multiple behaviours.
The Melbourne INFANT program was a 15-month cluster-randomized controlled trial involving 4-month-old infants and their parents at baseline in 2008 (n = 542). The intervention included six education sessions helping parents to promote a healthy diet, physical activity and limit sedentary behaviour in their infants. Participants were followed-up twice post-intervention, at ages 3.6 (2011) and 5 years (2013), to assess sustained effects of the intervention. Previous principal component analyses identified two lifestyle patterns from dietary intake, outdoor time and television viewing time. Random effect linear regression models were conducted to assess the impact of the intervention on lifestyle patterns.
The intervention group had a lower 'Discretionary consumption and TV' lifestyle pattern score than the control group at all time points with adjusted mean difference: -0.29, 95% CI -0.49, -0.09, p = 0.004 post-intervention at age 1.5 years; -0.29, 95% CI -0.54, -0.04, p = 0.02 at the first follow-up (age 3.6 years); and -0.21, 95% CI -0.43, 0.01, p = 0.06 at the second follow-up (age 5.0 years). No evidence of between-group differences was found for the 'Fruit, vegetables and outdoor' lifestyle pattern score.
This early childhood intervention designed to promote change in more than one obesity-related behaviour was effective in improving correlated unhealthy lifestyle behaviours. Lifestyle pattern analysis is a useful and interpretable approach for evaluating multi-behavioural interventions.
针对多种行为的干预措施的总体影响在很大程度上仍未得到探索。
本研究采用综合生活方式模式分析方法，评估早期儿童干预措施对多种行为变化的整体效果。
墨尔本婴儿计划（Melbourne INFANT program）是一项为期 15 个月的群组随机对照试验，于 2008 年在基线时纳入了 4 个月大的婴儿及其父母（n=542）。该干预措施包括 6 个教育课程，旨在帮助父母促进婴儿的健康饮食、身体活动和限制久坐行为。参与者在干预后进行了两次随访，分别在 3.6 岁（2011 年）和 5 岁（2013 年），以评估干预的持续效果。先前的主成分分析从饮食摄入、户外活动时间和看电视时间中确定了两种生活方式模式。采用随机效应线性回归模型评估干预对生活方式模式的影响。
干预组在所有时间点的“随意消费和电视”生活方式模式评分均低于对照组，调整后的平均差异为：干预后 1.5 岁时 -0.29（95%CI-0.49，-0.09，p=0.004）；第一次随访（3.6 岁时）时-0.29（95%CI-0.54，-0.04，p=0.02）；第二次随访（5.0 岁时）时-0.21（95%CI-0.43，0.01，p=0.06）。对于“水果、蔬菜和户外活动”生活方式模式评分，未发现组间差异的证据。
本研究旨在促进多种肥胖相关行为改变的儿童早期干预措施，对于改善相关的不健康生活方式行为是有效的。生活方式模式分析是评估多行为干预措施的一种有用且可解释的方法。
