The role of lifestyle choices in explaining how socioeconomic inequalities in health vary with age has received little attention. This study explores how the income and education gradients in both important lifestyle choices and self-assessed health (SAH) vary with age. Repeated cross-sectional data from Norway (n=25,016) and logistic regression models are used to track the income and education gradients in physical activity, smoking, consumption of fruit and vegetables and SAH over the age range 25-79 years. The education gradient in smoking, the income gradient in consumption of fruit and vegetables and the education gradient in physical activity among males become smaller at older ages. Physical activity among females is the only lifestyle indicator in which the income and education gradients grow stronger at older ages. In conclusion, this study shows that income and education gradients in lifestyle choices may not remain constant, but vary with age, and such variation could be important in explaining corresponding age patterns of inequality in health.
生活方式选择在解释健康方面的社会经济不平等如何随年龄变化这一问题上很少受到关注。本研究探讨了重要生活方式选择和自我评估健康（SAH）方面的收入和教育梯度如何随年龄变化。利用来自挪威的重复横断面数据（n = 25,016）和逻辑回归模型，追踪25至79岁年龄段在体育活动、吸烟、水果和蔬菜消费以及SAH方面的收入和教育梯度。男性吸烟方面的教育梯度、水果和蔬菜消费方面的收入梯度以及体育活动方面的教育梯度在老年时变小。女性的体育活动是唯一一项在老年时收入和教育梯度增强的生活方式指标。总之，本研究表明，生活方式选择方面的收入和教育梯度可能并非一成不变，而是随年龄变化，这种变化对于解释健康方面相应的年龄不平等模式可能很重要。
