This article aimed to examine the causal relationships of hours of work with health behaviors and health outcomes.
The data were derived from Japan Household Panel Survey/Keio Household Panel Survey. In total, data from 2677 men and 2170 women were analyzed to show the effects of hours of work on body mass index, smoking, and sleeping hours. To deal with the potential endogeneity of decisions about hours of work, the instrumental variable approach was used.
Hours of work had a negative impact on hours of sleep among men (coefficient [coef.], -0.371; 95% confidence interval [CI], -0.519 to -0.223). Longer hours of work also increased the probability of men being obese (coef., 1.108; 95% CI, 0.234-1.981) and the number of cigarettes they smoked each day (coef., 1.007; 95% CI, 0.037-1.978). For women, longer hours of work increased the probability of being obese (coef., 0.029; 95% CI, 0.009-0.050) and decreased the hours of sleep (coef., -0.416; 95% CI, -0.618 to -0.214).
This article suggests that the health consequences of long hours of work include health behaviors and health outcomes that can lead to higher risks of morbidity and mortality.
本文旨在探讨工作时间与健康行为和健康结果之间的因果关系。
数据来自日本家庭面板调查/庆应家庭面板调查。总共分析了 2677 名男性和 2170 名女性的数据，以显示工作时间对体重指数、吸烟和睡眠时间的影响。为了解决工作时间决策的潜在内生性问题，采用了工具变量法。
工作时间对男性的睡眠时间有负面影响（系数-0.371；95%置信区间-0.519 至-0.223）。工作时间延长也增加了男性肥胖的概率（系数 1.108；95%置信区间 0.234-1.981）和每天吸烟的数量（系数 1.007；95%置信区间 0.037-1.978）。对于女性，工作时间延长增加了肥胖的概率（系数 0.029；95%置信区间 0.009-0.050）和睡眠时间减少（系数-0.416；95%置信区间-0.618 至-0.214）。
本文表明，长时间工作的健康后果包括可能导致发病率和死亡率升高的健康行为和健康结果。
