The aim of this study was to examine various psychosocial, behavioral, and socio-environmental factors in a multiethnic sample of healthy-weight, overweight, and obese youths in the United States (US) and Mexico and determine differences by sex. We conducted a cross-sectional analysis of 633 youths aged 11-18 years who completed a self-reported questionnaire. Height and weight were measured to determine body mass index (BMI). Overweight and obese youth in both countries were significantly more likely to report a higher body image dissatisfaction (Odds Ratio (OR) = 1.67 and OR= 2.95, respectively), depressive symptoms (OR = 1.08 and OR = 1.12, respectively), perceive themselves as overweight (OR = 2.57) or obese (OR = 5.30), and a lower weight-specific quality of life (OR = 0.97 and OR = 0.95, respectively) than healthy-weight youth. Obese youth have lower healthy lifestyle priorities (OR = 0.75) and are less likely to be physically active (OR = 0.79) and eat breakfast (OR = 0.47) than healthy-weight youth. Additionally, overweight and obese youth are more likely to engage in weight control behaviors (OR = 5.19 and OR = 8.88, respectively) and restrained eating than healthy-weight youth. All the aforementioned results had a p-value of <0.05, which was considered statistically significant. The association between these factors and overweight or obesity remained significant after controlling for age, sex, race/ethnicity, and country. In conclusion, obesity was associated with a range of psychosocial, behavioral, and socio-environmental risk factors in both countries. Our findings support the need for multifactorial approaches when developing interventions to address the growing problem of obesity among youth in the US and Mexico.
本研究旨在考察美国和墨西哥的健康体重、超重和肥胖青少年的多种社会心理、行为和社会环境因素,并确定其性别差异。我们对 633 名 11-18 岁的青少年进行了横断面分析,这些青少年完成了一份自我报告问卷。通过测量身高和体重来确定体重指数(BMI)。研究结果表明,两国的超重和肥胖青少年更有可能报告更高的身体形象不满(优势比(OR)分别为 1.67 和 2.95)、抑郁症状(OR 分别为 1.08 和 1.12)、认为自己超重(OR = 2.57)或肥胖(OR = 5.30),以及较低的体重特异性生活质量(OR = 0.97 和 OR = 0.95),而健康体重的青少年则不然。肥胖青少年的健康生活方式优先级较低(OR = 0.75),不太可能进行身体活动(OR = 0.79)和吃早餐(OR = 0.47),而健康体重的青少年则不然。此外,超重和肥胖青少年更有可能进行体重控制行为(OR = 5.19 和 OR = 8.88)和节制饮食,而健康体重的青少年则不然。所有上述结果的 p 值均小于 0.05,被认为具有统计学意义。在控制年龄、性别、种族/民族和国家后,这些因素与超重或肥胖之间的关联仍然显著。总之,肥胖与两国青少年的一系列社会心理、行为和社会环境风险因素有关。我们的研究结果支持在制定干预措施时采取多因素方法的必要性,以解决美国和墨西哥青少年肥胖问题日益严重的问题。
