背景：为什么较低的社会经济群体行为不健康，只能部分解释为健康行为的直接成本。我们假设低收入会增加面临财务压力的风险。经历财务压力会占用认知“带宽”，导致自我控制能力下降，从而导致更不健康的行为。因此，我们的目标是调查（i）低收入是否会增加经历财务压力和不健康行为的可能性，（ii）在多大程度上更多的财务压力与自我控制能力降低有关，以及随后的（iii）自我控制能力降低是否与更不健康的行为有关。方法：从2014年荷兰地球仪研究第五波（N = 2812）的参与者（25-75岁）中获得横断面调查数据。收入，财务紧张，自我控制和健康行为相关的结果（闲暇时间的身体不活动，肥胖，吸烟，过量饮酒，每周水果和蔬菜摄入量）之间的关联进行了线性回归和广义线性回归模型（对数链接）分析。结果：与没有财务压力相比，经历巨大的财务压力增加了所有健康行为相关结果的风险，与收入无关。与高自我控制相比，低自我控制也增加了不健康生活方式的风险。考虑到自我控制，财务压力和结果之间的关联略有减弱。结论：巨大的财务压力和低自我控制力始终与不健康的行为有关。自我控制可能在一定程度上调节了经济压力和不健康行为之间的关系。缓解财政压力的干预措施可能会释放认知带宽并改善健康行为。
Background: Why lower socioeconomic groups behave less healthily can only partly be explained by direct costs of behaving healthily. We hypothesize that low income increases the risk of facing financial strain. Experiencing financial strain takes up cognitive 'bandwidth' and leads to less self-control, and subsequently results in more unhealthy behaviour. We therefore aim to investigate (i) whether a low income increases the likelihood of experiencing financial strain and of unhealthy behaviours, (ii) to what extent more financial strain is associated with less self-control and, subsequently, (iii) whether less self-control is related to more unhealthy behaviour. Methods: Cross-sectional survey data were obtained from participants (25-75 years) in the fifth wave of the Dutch GLOBE study (N = 2812) in 2014. The associations between income, financial strain, self-control and health-behaviour-related outcomes (physical inactivity in leisure-time, obesity, smoking, excessive alcohol intake, and weekly fruit and vegetable intake) were analysed with linear regression and generalized linear regression models (log link). Results: Experiencing great compared with no financial strain increased the risk of all health-behaviour-related outcomes, independent of income. Low self-control, as compared with high self-control, also increased the risk of an unhealthy lifestyle. Taking self-control into account slightly attenuated the associations between financial strain and the outcomes. Conclusion: Great financial strain and low self-control are consistently associated with unhealthy behaviours. Self-control may partly mediate between financial strain and unhealthy behaviour. Interventions that relieve financial strain may free up cognitive bandwidth and improve health behaviour.
