Longitudinal evidence of relationships between unhealthy diets and BMI in children is crucial for appropriately targeting obesity prevention activities. The objective was to determine the relationship between frequency of consumption of sugar sweetened beverages (SSBs) and high fat foods (HFFs) and body weight in Australian children aged from 4 to 10 years.
Data from 4,164 children participating in four waves (wave 1, 2004; wave 2, 2006; wave 3, 2008; and wave 4, 2010) of the Longitudinal Study of Australian Children were analyzed. A multi-level growth model tested relationships between consumption of SSB and HFF and BMI z-scores.
BMI z-scores were associated with daily consumption of HFF, SSB and maternal BMI independent of BMI z-scores at wave 1 (baseline); with each additional occurrence of SSB and HFF consumption intake per day, BMI z-score increased by 0.015 U (P < 0.01) and 0.014 U (P < 0.001), respectively. With each additional maternal BMI unit, BMI z-score increased by 0.032 (P < 0.001).
Higher BMI z-scores were strongly associated with the consumption of SSBs and HFFs. Future efforts to prevent obesity should consider urgent action to address the impact of the consumption of SSBs and HFFs in childhood.
儿童时期不良饮食与 BMI 之间关系的纵向证据对于有针对性地开展肥胖预防活动至关重要。本研究旨在确定澳大利亚 4 至 10 岁儿童中，饮用含糖饮料（SSB）和高脂肪食物（HFF）的频率与体重之间的关系。
对参与澳大利亚儿童纵向研究（LSAC）4 个波次（第 1 波次，2004 年；第 2 波次，2006 年；第 3 波次，2008 年；第 4 波次，2010 年）的 4164 名儿童的数据进行了分析。使用多层次增长模型检验了 SSB 和 HFF 摄入量与 BMI z 评分之间的关系。
BMI z 评分与 HFF 和 SSB 的每日摄入量相关，与第 1 波次（基线）的 BMI z 评分无关；SSB 和 HFF 的每日摄入量每增加一次，BMI z 评分分别增加 0.015 U（P < 0.01）和 0.014 U（P < 0.001）。母亲 BMI 每增加一个单位，BMI z 评分增加 0.032（P < 0.001）。
较高的 BMI z 评分与 SSB 和 HFF 的摄入密切相关。未来预防肥胖的工作应考虑采取紧急行动，解决儿童时期 SSB 和 HFF 摄入的影响。
