项目摘要
Project Summary/Abstract
Identifying causal relations is fundamental to a science of intervention and prevention. Obesity is a major problem
for which much progress in understanding, treatment, and prevention remains to be made. Behavior is a vital
contributor to variations in energy balance and body composition, the final common pathways of obesity. Social,
environmental and physiological factors are also key influences on behaviors which affect energy balance.
Evidence for causation of these hypothesized factors exists on a continuum from weakest to strongest. Yet, most
obesity research does not consider the evidence continuum between ordinary association tests (OATs)
(observational, non-intervention studies among unrelated individuals), which do not offer strong evidence of
causal effects, and randomized controlled trials (RCTs), which do offer strong evidence, but cannot be done in
all circumstances. In contrast, there are techniques that lie intermediary between OATs and RCTs, including but
not limited to quasi-experimental studies and natural experiments. Such designs are increasingly used,
especially in the disciplines of economics and genetics, but are used by obesity researchers less often than
seems warranted. Our ability to draw causal inferences in obesity research could be strengthened by using such
approaches. In-depth understanding and appropriate use of the full continuum of these methods requires input
from disciplines including statistics, economics, psychology, epidemiology, mathematics, philosophy, and
behavioral or statistical genetics. Applying these techniques, however, does not involve routine ‘cookbook’
approaches but requires understanding of underlying principles, so the investigator can tailor approaches to
specific and varying situations. Yet, other than our annual 5-day short course, no resource provides such training,
particularly for behavioral and social science researchers. Our short course on methods for causal inference in
obesity research, which features some of the world’s finest scientists, has been consistently evaluated by
attendees as essential for their research and teaching. The course provides rigorous exposure to the key
fundamental principles underlying a broad array of techniques and experience in application through guided
discussion using real examples. The course is dynamic in that we refine and modify its content and delivery
methods based on feedback from stakeholders. In this renewal application, we propose to continue to offer this
course, alternating its location between Indiana University and the University of Alabama at Birmingham. Given
the prevalence of obesity and its related health problems, training behavioral and social science researchers to
better assess causal effects is more important than ever.
项目总结/摘要
确定因果关系是干预和预防科学的基础。肥胖是一个主要问题
在认识、治疗和预防方面仍有很大进展。行为是至关重要的
这是导致能量平衡和身体成分变化的因素,也是肥胖的最终共同途径。社交,
环境和生理因素也是影响能量平衡的行为的关键影响因素。
这些假设因素的因果关系的证据存在于从最弱到最强的连续体上。然而,大多数
肥胖研究没有考虑普通关联检验(OAT)之间的证据连续性
(在无关个体中进行的观察性、非干预性研究),这些研究没有提供强有力的证据,
因果效应和随机对照试验(RCT),这些试验确实提供了强有力的证据,但不能在
所有的情况。相反,有一些技术介于OAT和RCT之间,包括但不限于
不限于准实验研究和自然实验。这种设计越来越多地被使用,
尤其是在经济学和遗传学领域,但肥胖研究人员使用的频率低于
似乎是有道理的。我们在肥胖研究中得出因果推论的能力可以通过使用这种方法来加强。

行为或统计遗传学。然而,应用这些技术并不涉及常规的“食谱”。

特别是对于行为和社会科学研究者来说。我们的短期课程因果推理的方法,
肥胖研究,其中包括一些世界上最优秀的科学家,一直受到评估,
与会者对他们的研究和教学至关重要。该课程提供了严格的接触的关键
基本原则的基础广泛的技术和经验的应用,通过指导
使用真实的例子进行讨论。该课程是动态的,因为我们改进和修改其内容和交付
基于利益相关者反馈的方法。在这次更新申请中,我们建议继续提供这种
课程,交替在印第安纳州大学和伯明翰的亚拉巴马大学之间的位置。给定
肥胖及其相关健康问题的流行,培训行为和社会科学研究人员,
更好地评估因果效应比以往任何时候都更加重要。
