To evaluate the agreement between body mass index (BMI) parameters applied to children aged six to ten years in the city of Montes Claros (MG), Brazil with national and international criteria, also calculating their sensitivity and specificity regarding excess weight screening.
A sample comprising 4151 children aged six to ten years was assessed, with height and body mass determined for BMI calculation. The obtained values were classified according to cutoff points established by the World Health Organization (WHO), International Obesity Task Force (IOTF), Centers for Disease Control and Prevention (CDC), Conde & Monteiro, and a recent local proposal. The agreement index between the mentioned criteria was calculated and thereafter the sensitivity and specificity.
The local proposal was proven to be highly consistent in most combinations, especially concerning the excess weight criteria of the World Health Organization (WHO) (k=0.895). Regarding excess weight, the local proposal presented sensitivity and specificity values of 0.8680 and 0.9956, respectively, indicating high BMI discrimination power.
The locally applied BMI parameters for children aged six to ten years represent a valid, highly viable and practical proposal for excess weight screening in this population group, improving professional decision-making in their follow-up.
评估巴西蒙特克莱尔市（MG）6 至 10 岁儿童的体重指数（BMI）参数与国家和国际标准之间的一致性，并计算其在超重筛查方面的灵敏度和特异性。
评估了 4151 名 6 至 10 岁的儿童，测量身高和体重以计算 BMI。根据世界卫生组织（WHO）、国际肥胖工作组（IOTF）、疾病控制与预防中心（CDC）、Conde & Monteiro 和最近的当地建议确定的截断点对所获得的值进行分类。计算了所述标准之间的一致性指数，然后计算了灵敏度和特异性。
该本地建议在大多数组合中被证明具有高度一致性，尤其是针对世界卫生组织（WHO）的超重标准（k=0.895）。在超重方面，该本地建议的灵敏度和特异性值分别为 0.8680 和 0.9956，表明 BMI 具有较高的区分能力。
适用于 6 至 10 岁儿童的本地 BMI 参数代表了一种有效、高度可行和实用的超重筛查方法，可改善该人群随访中的专业决策。
