ABSTRACT Recent evidence indicates a slight decline in the overall prevalence of obesity in New Zealand children (including Māori), but it is unknown whether this pattern is reflected across all iwi. We examined obesity prevalence (body mass index (BMI) ≥95th percentile) among 4-year-old children of Ngāti Whātua descent (n = 2031) enrolled in the B4 School Check from 2010 to 2016. Possible differences according to sociodemographic factors were examined. There was no evidence that obesity prevalence among Ngāti Whātua children changed throughout the study period. Mean prevalence was 21.2%, but there was marked yearly variation, ranging from 17.5% to 23.2%. Overall, mean prevalence differed according to sociodemographic factors, being higher in boys than girls (24.5% vs 17.9%) and among children from most deprived compared to least deprived households (25.5% vs 16.2%). Their overall mean BMI z-score was 0.88 (95%CI 0.84, 0.93), with sociodemographic differences mirroring those for prevalence: boys 0.99 vs girls 0.78; and most deprived 0.90 vs least deprived households 0.76. In conclusion, In contrast to national figures, obesity prevalence among Ngāti Whātua children appeared to be unchanged throughout the study period, indicating national data from the larger Māori population in New Zealand cannot be assumed to reflect the trends within individual iwi.

2010-2016 年 Ngāti Whātua 4 岁儿童肥胖患病率稳定

摘要 最近的证据表明，新西兰儿童（包括毛利人）的肥胖总体流行率略有下降，但尚不清楚这种模式是否反映在所有 iwi 中。我们检查了 2010 年至 2016 年参加 B4 学校检查的 Ngāti Whātua 血统的 4 岁儿童（n = 2031）的肥胖患病率（体重指数 (BMI) ≥ 95th%）。检查了根据社会人口学因素的可能差异. 没有证据表明 Ngāti Whātua 儿童的肥胖率在整个研究期间发生了变化。平均患病率为 21.2%，但存在显着的年度变化，范围从 17.5% 到 23.2%。总体而言，平均患病率因社会人口因素而异，男孩高于女孩（24.5% vs 17.0%）。9%）以及来自最贫困家庭的儿童与最贫困家庭的儿童（25.5% 对 16.2%）。他们的总体平均 BMI z 得分为 0.88（95%CI 0.84，0.93），社会人口统计学差异反映了患病率的差异：男孩 0.99 与女孩 0.78；最贫困家庭 0.90 与最贫困家庭 0.76。总之，与全国数据相比，Ngāti Whātua 儿童的肥胖患病率在整个研究期间似乎没有变化，这表明新西兰毛利人的全国数据不能反映个体 iwi 的趋势。
