Research on health correlates in gamblers has found an association between gambling and obesity. The neurocognitive underpinnings of impulsivity may be useful targets for understanding and ultimately treating individuals with both gambling and obesity problems.
207 non-treatment seeking young adults (18-29 years) with subsyndromal gambling disorder were recruited from the community. Subjects were grouped according to weight ('normal weight' BMI<25, 'overweight' BMI≥25; or 'obese' BMI≥30). Measures relating to gambling behaviour and objective computerized neurocognitive measures were collected.
Of the 207 subjects, 22 (10.6%) were obese and 49 (23.7%) were overweight. The obese gamblers consumed more nicotine (packs per day equivalent) and reported losing more money per week to gambling. Obese gamblers exhibited significant impairments in terms of reaction times for go trials on the stop-signal test (SST), quality of decision making and risk adjustment on the Cambridge Gamble Test (CGT), and sustained attention on the rapid visual information processing task (RVP).
Obesity was associated with decision making and sustained attention impairments in gamblers, along with greater monetary loss due to gambling. Future work should use longitudinal designs to examine the temporal relationship between these deficits, weight, other impulsive behaviour, and functional impairment.
对赌博者健康相关性的研究发现赌博与肥胖之间存在关联。冲动性的神经认知基础可能是理解并最终治疗同时存在赌博和肥胖问题个体的有用靶点。
从社区招募了207名患有亚综合征赌博障碍且未寻求治疗的年轻人（18 - 29岁）。根据体重将受试者分组（“正常体重”BMI<25，“超重”BMI≥25；或“肥胖”BMI≥30）。收集了与赌博行为相关的测量数据以及客观的计算机化神经认知测量数据。
在207名受试者中，22人（10.6%）肥胖，49人（23.7%）超重。肥胖的赌博者消耗更多尼古丁（每天相当于包数），且报告每周赌博输钱更多。在停止信号测试（SST）的“继续”试验反应时间、剑桥赌博测试（CGT）的决策质量和风险调整以及快速视觉信息处理任务（RVP）的持续注意力方面，肥胖的赌博者表现出显著受损。
肥胖与赌博者的决策和持续注意力受损有关，同时因赌博导致的金钱损失更大。未来的研究应采用纵向设计来检验这些缺陷、体重、其他冲动行为和功能损害之间的时间关系。
