To investigate the sociodemographic and behavioural factors associated with incidence, persistence or remission of obesity in a longitudinal sample of Australian children aged 4-10 years.
Nationally representative Longitudinal Study of Australian Children (LSAC).
The sample for this analysis included all children in the Kinder cohort (aged 4-5 years at wave 1) who participated in all four waves of LSAC (wave 1, 2004, aged 4-5 years; wave 2, 2006, aged 6-7 years; wave 3, 2008, aged 8-9 years and wave 4, 2010, aged 10-11 years). Of the 4983 children who participated in the baseline (wave 1) survey, 4169 (83.7%) children completed all four waves of data collection.
Movement of children between weight status categories over time and individual-level predictors of weight status change (sociodemographic characteristics, selected dietary and activity behaviours).
The study found tracking of weight status across this period of childhood. There was an inverse association observed between socioeconomic position and persistence of overweight/obesity. Sugar-sweetened beverages and fruit and vegetable intake and screen time appeared to be important predictors of stronger tracking.
Overweight and obesity established early in childhood tracks strongly to the middle childhood years in Australia, particularly among children of lower socioeconomic position and children participating in some unhealthy behaviour patterns.
在4至10岁澳大利亚儿童的纵向样本中，调查与肥胖症的发病率、持续存在或缓解相关的社会人口学和行为因素。
具有全国代表性的澳大利亚儿童纵向研究（LSAC）。
本次分析的样本包括幼儿队列中的所有儿童（第1波时年龄为4至5岁），他们参与了LSAC的所有四轮调查（第1波，2004年，年龄4至5岁；第2波，2006年，年龄6至7岁；第3波，2008年，年龄8至9岁；第4波，2010年，年龄10至11岁）。在参与基线（第1波）调查的4983名儿童中，4169名（83.7%）儿童完成了所有四轮数据收集。
儿童体重状况类别随时间的变化以及体重状况变化的个体水平预测因素（社会人口学特征、选定的饮食和活动行为）。
研究发现，在整个童年时期体重状况具有追踪性。社会经济地位与超重/肥胖的持续存在之间存在负相关。含糖饮料、水果和蔬菜摄入量以及屏幕时间似乎是更强追踪性的重要预测因素。
在澳大利亚，儿童早期出现的超重和肥胖在童年中期具有很强的追踪性，尤其是在社会经济地位较低的儿童以及参与某些不健康行为模式的儿童中。
