背景。根据Rose倡导的单一分布理论，过度饮酒等异常情况的流行程度取决于人群中相应特征的平均水平。本研究的目的是确定单一分布理论是否适用于赌博行为方法。利用1994年11月引进国家彩票前后收集的家庭支出调查数据，对联合王国的家庭赌博支出进行了审查。结果。在横断面分析中，每个地区的平均（或中位数）家庭赌博支出预测了该地区过度赌博的流行程度：1995-96年关系的斜率相当于家庭赌博支出每增加1英镑，赌博超过收入10%的家庭百分比增加1.2点（95% CI 0.7-1.7）。国家彩票的引入使家庭平均赌博支出从每周1.45英镑增加到3.81英镑，赌博占总收入10%以上的家庭比例增加了四倍，从0.4%增加到1.7%。在每周收入低于200英镑的家庭中，赌博占其收入超过10%的比例从0.6%上升到3.2%。解释。单一分配理论适用于赌博行为。随着英国国家彩票的引入，平均赌博支出的增加导致过度赌博的盛行率明显增加，特别是在低收入家庭中。这可能会增加赌博障碍的流行程度，并加剧健康方面的一系列不平等。
Background. According to the single distribution theory advocated by Rose, the prevalence of a deviant condition such as excessive alcohol consumption depends upon the average level of the corresponding characteristic in the population. The objective of this study was to establish whether the single distribution theory applies to gambling behaviour Methods. Household gambling expenditure in the United Kingdom was Examined using Family Expenditure Survey data collected before and after the introduction of a national lottery in November 1994. Results. In cross-sectional analyses, the mean (or median) household expenditure on gambling for each region predicted the prevalence of excessive gambling in that region: the slope of the relationship in 1995-96 was equivalent to an increase of 1.2 (95% CI 0.7-1.7) points in the percentage of households gambling more than 10% of income for every increase of pound 1 in mean household gambling expenditure. The introduction of the national lottery was associated with an increase in mean household gambling Expenditure from pound 1.45 to pound 3.81 per week, and an increase in the proportion of households gambling more than 10% of total income four-fold from 0.4% to 1.7%. Among households with income of less than pound 200/week, the proportion gambling more than 10% of their income increased from 0.6% to 3.2%. Interpretation. The single distribution theory applies to gambling behaviour. The increase in average gambling expenditure associated with the introduction of a national lottery in the United Kingdom has led to a pronounced increase in the prevalence of excessive gambling, especially in low-income households. This is likely to increase the prevalence of gambling disorders and to exacerbate serial inequalities in health.
