Overweight (OW) and obesity (OB) during childhood/adolescence are major public health problems in Mexico. Several obesogenic lifestyle (OL) risk factors have been identified, but the burden and consequences of them in Mexican children/adolescents remain unclear. The objective of this study was to estimate the prevalence of OL components and describe their relationships with adiposity, and OW/OB. A population-based cross-sectional study of Mexican children/adolescents with nutritional assessment, data collection on daily habits and adiposity as fat-mass index (FMI) by dual-energy X-ray absorptiometry was performed. Individual OL-components: "inactivity," "excessive screen time," "insufficient sleep," "unhealthy-diet", were defined according to non-adherence to previously published healthy recommendations. : 1449 subjects were assessed between March 2015 to April 2018. Sixteen percent of subjects had all four OL-components, 40% had three, 35% had two, 9% had one, and 0.5% had none. A cumulative OL score showed a significant dose-response effect with FMI. The combination of inactivity, excessive screen time, and insufficient sleep showed the highest risk association to OW/OB and higher values of FMI. : The prevalence of OL-components was extremely high and associated with increased adiposity and OW/OB. Several interventions are needed to revert this major public health threat.
超重（OW）和肥胖（OB）在儿童和青少年时期是墨西哥的主要公共卫生问题。已经确定了几种致肥胖的生活方式（OL）危险因素，但墨西哥儿童和青少年的 OL 危险因素的负担和后果仍不清楚。本研究的目的是估计 OL 成分的流行率，并描述它们与肥胖和 OW/OB 的关系。这是一项基于人群的墨西哥儿童和青少年的横断面研究，对其进行营养评估，收集日常生活习惯数据，并通过双能 X 射线吸收法测量体脂肪指数（FMI）来评估肥胖程度。个体 OL 成分：“缺乏运动”、“过度使用电子屏幕”、“睡眠不足”、“不健康饮食”，根据先前发表的健康建议的不依从性来定义。：2015 年 3 月至 2018 年 4 月期间评估了 1449 名受试者。16%的受试者有四个 OL 成分，40%有三个，35%有两个，9%有一个，0.5%没有。OL 评分的累积分数与 FMI 呈显著剂量反应关系。缺乏运动、过度使用电子屏幕和睡眠不足的组合与 OW/OB 以及更高的 FMI 值风险相关性最高。：OL 成分的流行率极高，与肥胖和 OW/OB 有关。需要采取多种干预措施来扭转这一主要的公共卫生威胁。
