Migrants from developing to developed countries rapidly develop more obesity than the host population. While the effects of socio-economic status on obesity are well established, the influence of cultural factors, including acculturation, is not known.
To examine the association between acculturation and obesity and its risk factors among African migrant children in Australia.
A cross-sectional study using a non-probability sample of 3- to 12-year-old sub-Saharan African migrant children. A bidimensional model of strength of affiliation with African and Australian cultures was used to divide the sample into four cultural orientations: traditional (African), assimilated (Australian), integrated (both) and marginalized (neither).
Body mass index (BMI), leisure-time physical activity (PA) and sedentary behaviours (SBs) and energy density of food.
In all, 18.4% (95% confidence interval (CI): 14-23%) were overweight and 8.6% (95% CI: 6-12%) were obese. After adjustment for confounders, integrated (beta=1.1; P<0.05) and marginalized (beta=1.4; P<0.01) children had higher BMI than traditional children. However, integrated children had significantly higher time engaged in both PA (beta=46.9, P<0.01) and SBs (beta=43.0, P<0.05) than their traditional counterparts. In comparison with traditional children, assimilated children were more sedentary (beta=57.5, P<0.01) while marginalization was associated with increased consumption of energy-dense foods (beta=42.0, P<0.05).
Maintenance of traditional orientation was associated with lower rates of obesity and SBs. Health promotion programs and frameworks need to be rooted in traditional values and habits to maintain and reinforce traditional dietary and PA habits, as well as identify the marginalized clusters and address their needs.
从发展中国家迁移至发达国家的移民比当地居民更容易迅速肥胖。虽然社会经济地位对肥胖的影响已得到充分证实，但包括文化适应在内的文化因素的影响尚不清楚。
研究澳大利亚非洲移民儿童的文化适应与肥胖及其危险因素之间的关联。
一项横断面研究，采用非概率抽样方法，选取3至12岁的撒哈拉以南非洲移民儿童。运用与非洲和澳大利亚文化的归属强度二维模型将样本分为四种文化取向：传统型（非洲文化）、同化型（澳大利亚文化）、融合型（两种文化）和边缘化型（两种文化都不归属）。
体重指数（BMI）、休闲时间身体活动（PA）、久坐行为（SBs）以及食物的能量密度。
总体而言，18.4%（95%置信区间（CI）：14%-23%）的儿童超重，8.6%（95%CI：6%-12%）的儿童肥胖。在对混杂因素进行调整后，融合型（β=1.1；P<0.05）和边缘化型（β=1.4；P<0.01）儿童的BMI高于传统型儿童。然而，融合型儿童参与PA（β=46.9，P<0.01）和SBs（β=43.0，P<0.05）的时间显著长于传统型儿童。与传统型儿童相比，同化型儿童久坐时间更长（β=57.5，P<0.01），而边缘化与能量密集型食物的摄入量增加有关（β=42.0，P<0.05）。
保持传统取向与较低的肥胖率和SBs发生率相关。健康促进计划和框架需要植根于传统价值观和习惯，以维持和强化传统饮食及身体活动习惯，并识别边缘化群体并满足他们的需求。
