The study was conducted to determine whether state obesity-prevalence rates can be predicted by state differences in residents' levels on the Big Five personality variables (O. P. John & S. Srivastava, 1999). State obesity prevalence was the mean percentage of the state population from 2000 to 2005 with a body mass index > or = 30.0 as assessed by the Behavioral Risk Factor Surveillance System (Centers for Disease Control and Prevention, 2010), which currently interviews more than 350,000 adults annually. State neuroticism, extraversion, agreeableness, conscientiousness, and openness z scores, based on the responses of 619,397 residents to an Internet survey from 1999 to 2005, were taken from P. J. Rentfrow, S. D. Gosling, and J. Potter (2008). Alaska, Hawaii, and North Dakota had scores outside -3 and +3 standard deviations on at least 1 variable and were excluded as outliers. For the 47 remaining states, state obesity prevalence was significantly correlated with neuroticism (.35), agreeableness (.38), openness (-.44), socioeconomic status (-.74), white percentage (-.34), and urbanization (-.43). Multiple regression analysis showed that socioeconomic status could account for 54.0% of the criterion variance and that agreeableness, neuroticism, and openness together could account for another 17.1%.
这项研究旨在确定州居民的大五人格变量差异是否可以预测州肥胖流行率（O. P. John 和 S. Srivastava，1999）。州肥胖流行率是指 2000 年至 2005 年期间，根据行为风险因素监测系统（疾病控制与预防中心，2010 年）评估的州人口中身体质量指数（BMI）大于或等于 30.0 的平均值，该系统目前每年对超过 350,000 名成年人进行访谈。根据 619,397 名居民对 1999 年至 2005 年互联网调查的回答，得出了州神经质、外向性、宜人性、尽责性和开放性 z 分数，这些分数来自 P. J. Rentfrow、S. D. Gosling 和 J. Potter（2008 年）。阿拉斯加、夏威夷和北达科他州在至少一个变量上的得分低于-3 和+3 标准差，因此被排除在外作为异常值。对于其余的 47 个州，州肥胖流行率与神经质（.35）、宜人性（.38）、开放性（-.44）、社会经济地位（-.74）、白种人比例（-.34）和城市化（-.43）显著相关。多元回归分析表明，社会经济地位可以解释 54.0%的准则方差，而宜人性、神经质和开放性可以共同解释另外 17.1%。
