The purpose of this research was to empirically derive a typology of obese persons and validate a typology derived in earlier research (Allison & Heshka [1991] International Journal of Obesity). Biological, behavioral, and psychological variables were assessed through survey among 719 (641 females, 78 males) obese members of The National Association to Advance Fat Acceptance (NAAFA). All variables were subjected to principal components analyses which extracted 12 biological and 12 psychological components. A two-cluster solution from a k-means clustering on biological components was replicated via Ward's method. Agreement between the solutions was significant (Phi = .33, Kappa = .19, p < .05). The solution was validated through entering psychological component scores into discriminant analysis. One significant function (p < .001) substantially separated the clusters. A component measuring early onset/familial history powerfully discriminated between the clusters. Early onset obese were more obese, more active, and restricted caloric intake to a greater degree. Late onset obese were more likely to be "settled down," engage in substance abuse, eat at night, and have diabetes (p < .05). Results were substantially consistent with those of prior research.
本研究的目的是通过实证得出肥胖者的类型学，并验证早期研究（Allison & Heshka [1991]《国际肥胖杂志》）中得出的类型学。通过对全国促进肥胖接受协会（NAAFA）的719名肥胖成员（641名女性，78名男性）进行调查，评估了生物、行为和心理变量。所有变量都进行了主成分分析，提取了12个生物成分和12个心理成分。通过Ward方法对生物成分进行k均值聚类得到的两聚类解决方案进行了重复验证。两种解决方案之间的一致性显著（Phi = 0.33，Kappa = 0.19，p < 0.05）。通过将心理成分得分输入判别分析来验证该解决方案。一个显著函数（p < 0.001）将聚类显著分开。一个测量早发/家族史的成分在聚类之间有很强的区分能力。早发肥胖者更肥胖、更活跃，并且热量摄入限制程度更高。晚发肥胖者更有可能“安定下来”、滥用药物、在夜间进食并且患有糖尿病（p < 0.05）。结果与先前研究的结果基本一致。
