Abstract：
UNASSIGNED: There is limited evidence on recent trends in childhood growth trajectories in Low-/middle-income countries. We investigated how age-trajectories for height and Body Mass Index (BMI) have changed among Brazilian children born in two different time periods after 2000.
UNASSIGNED: We used a population-based cohort (part of the \"Cohort of 100-Million Brazilians\") created by the linkage of three Brazilian administrative databases: the Cadastro Único of the Federal Government, the National System of Live Births and the National Nutritional and Food Surveillance System. We included longitudinal data on 5,750,214 children who were 3 to <10 years of age and born between 2001 and 2014 (20,209,133 observations). We applied fractional polynomial models with random-effects to estimate mean height and BMI trajectories for children.
UNASSIGNED: Compared to children born in 2001-2007, the cohort born in 2008-2014 were on average taller, by a z-score of 0.15 in boys and 0.12 in girls. Their height trajectories shifted upwards, by approximately 1 cm in both sexes. Levels of BMI increased little, by a z-score of 0.06 (boys) and 0.04 (girls). Mean BMI trajectories also changed little. However, the prevalence of overweight/obesity increased between cohorts, e.g., from 26.8% to 30% in boys and 23.9%-26.6% in girls aged between 5 and <10 years.
UNASSIGNED: An increase of 1 cm in mean height of Brazilian children during a short period indicates the improvement in maternal and child health, especially those from low-income families due to the new health and welfare policies in Brazil. Although mean BMI changed little, the prevalence of child overweight/obesity slightly increased and remained high.

摘要：
■关于低收入/中等收入国家儿童成长轨迹的最新趋势的证据有限。我们调查了2000年后在两个不同时间段出生的巴西儿童的身高和体重指数（BMI）的年龄轨迹如何变化。
■我们使用了一个基于人口的队列（“1亿巴西人队列”的一部分），该队列是由三个巴西行政数据库的链接创建的：联邦政府的Cadastro乌尼科，国家活产系统和国家营养和食品监测系统。我们纳入了2001年至2014年出生的5,750,214名3至<10岁儿童的纵向数据（20,209,133观察）。我们应用具有随机效应的分数多项式模型来估计儿童的平均身高和BMI轨迹。
■与2001-2007年出生的孩子相比，2008-2014年出生的孩子平均较高，男孩的z评分为0.15，女孩的z评分为0.12。他们的高度轨迹向上移动，男女大约1厘米。BMI水平几乎没有增加，z分数为0.06（男孩）和0.04（女孩）。平均BMI轨迹也变化不大。然而,超重/肥胖的患病率在队列之间增加，例如，从26.8%到30%的男孩和23.9%-26.6%的女孩年龄在5和<10岁之间。
■巴西儿童在短时间内平均身高增加1厘米，表明母婴健康有所改善，特别是那些来自低收入家庭由于新的健康和福利政策在巴西。虽然平均BMI变化不大，儿童超重/肥胖的患病率略有上升,且仍然很高.
