To identify modifiable risk factors for obesity among low socioeconomic status (LSES) children.
Cross-sectional data were obtained from 238 4-7-year-old children and 224 mothers from LSES preschools. Anthropometric measurements were obtained; mothers were interviewed about sociodemographic characteristics, health behaviors, perceptions and beliefs.
The combined prevalence of overweight and obesity (OWOB) among children was 29.8% based on the new World Health Organization (WHO) growth standard. Prevalence of OWOB (body mass index ≥25) among mothers was 51.8%. Mean age, sleeping hours, gender distribution and poverty level were similar between normal and OWOB children. Over 82% of mothers underestimated their child's weight status. Of the 62 OWOB children, 74.2% were perceived by their mothers as having 'normal weight' (NW) and 8% were perceived as 'thin'. Mothers perceived 67 out of 158 NW children (42.4%) as 'thin' (P<0.001). Mediation analysis indicated that 10% of the effect of maternal underestimation on child's OWOB may be mediated through child's daily sedentary hours (P=0.06). In a multivariable logistic-regression analysis controlling for maternal obesity, knowledge regarding breakfast's importance and child's daily sedentary hours, maternal underestimation of the child's weight status (odds ratio=7.33; 95% confidence interval (CI):2.41-22.37; P<0.0001) and parental smoking (odds ratio=3.25; 95% CI: 1.26-8.40; P=0.015) were the only significant factors associated with OWOB in LSES children.
Maternal perception of child's weight status and parental smoking are associated with childhood OWOB among LSES children. These parameters can help identify children at risk for obesity. Maternal perception may be amenable to intervention.
确定社会经济地位较低（LSES）儿童肥胖的可改变风险因素。
从 LSES 幼儿园的 238 名 4-7 岁儿童和 224 名母亲那里获得了横断面数据。进行了人体测量学测量；对母亲进行了社会人口统计学特征、健康行为、看法和信念的访谈。
根据新的世界卫生组织（WHO）生长标准，儿童超重和肥胖（OWOB）的合并患病率为 29.8%。母亲 OWOB（体重指数≥25）的患病率为 51.8%。正常体重和 OWOB 儿童的平均年龄、睡眠时间、性别分布和贫困水平相似。超过 82%的母亲低估了孩子的体重状况。在 62 名 OWOB 儿童中，有 74.2%的母亲认为自己的孩子体重“正常”（NW），有 8%的母亲认为自己的孩子“瘦”。母亲认为 158 名 NW 儿童中有 67 名（42.4%）“瘦”（P<0.001）。中介分析表明，母亲低估对孩子 OWOB 的影响有 10%可能通过孩子每天的久坐时间来介导（P=0.06）。在控制母亲肥胖、早餐重要性知识和孩子每天久坐时间的多变量逻辑回归分析中，母亲对孩子体重状况的低估（比值比=7.33；95%置信区间（CI）：2.41-22.37；P<0.0001）和父母吸烟（比值比=3.25；95%CI：1.26-8.40；P=0.015）是与 LSES 儿童 OWOB 相关的唯一显著因素。
母亲对孩子体重状况的看法和父母吸烟与 LSES 儿童的儿童 OWOB 有关。这些参数可以帮助识别肥胖风险儿童。母亲的认知可能容易受到干预。
