在美国，肥胖和社会经济地位（SES），或一个人在社会上的地位，基于收入，教育和/或职业，是密切相关的。这种关系的机制可能包括具有高水平的获得食物的动机（食物的强化价值; RRV）和低水平的抑制控制（延迟折扣; DD），当两者结合时，被称为强化病理学（RP）。我们试图研究家庭SES，RP和青少年年龄调整后的身体质量指数（zBMI）的多项措施之间的关系。这些数据是作为正在进行的244名青少年肥胖危险因素纵向研究的一部分收集的。测量青少年和一名父母/监护人的身高和体重，并完成调查。青少年完成了调整量DD任务和基于计算机的RRV任务。分析包括SES和RRV、DD和BMI z评分测量值之间的相关性。在显著相关的情况下，使用理论上知情的协变量创建多元回归模型。家庭收入，父母/监护人的教育，父母/监护人的职业，和粮食不安全状况都相互关联。在青少年中，在控制协变量后，家庭收入占RRV方差的很大一部分。对于DD，在控制协变量后，父母/监护人教育最相关。当低收入和低父母/监护人教育同时发生时，RP的风险可能会增加。另外，食物不安全预示着父母/监护人BMI较高。未来的研究应继续探讨低收入和父母/监护人的教育对RP在青少年中的影响，通过检查他们随着时间的推移。在线版本包含补充材料，可通过10.1186/s12889-021-10430-7获得。
In the United states obesity and socioeconomic status (SES), or one’s standing in society based on income, education, and/or occupation, are strongly associated. The mechanisms for this relationship may include having high levels of motivation to get food (reinforcing value of food; RRV) and low levels of inhibitory control (delay discounting; DD) which, when combined, is referred to as reinforcement pathology (RP). We sought to examine the relationships among multiple measures of household SES, RP, and age-adjusted body mass index (zBMI) among adolescents. These data were collected as part of ongoing longitudinal study of risk factors for obesity in 244 adolescents. The adolescents and one parent/guardian had height and weight measured and completed surveys. The adolescents completed an adjusting amount DD task and a computer-based RRV task. Analyses consisted of correlations among measures of SES and RRV, DD, and BMI z-scores. In the case of significant associations, multiple regression models were created with theoretically informed covariates. Household income, parent/guardian education, parent/guardian occupation, and food insecurity status were all related to one another. Among the adolescents, a significant portion of the variance in RRV was accounted for by household income after controlling for covariates. For DD, it was parent/guardian education that was most associated after controlling for covariates. When low income and low parent/guardian education occur together, there may be an increased risk of RP. Separately, food insecurity was predictive of higher parent/guardian BMI. Future research should continue to explore the effects of low income and parent/guardian education on RP among youth by examining them over time.
