This study examined how social class, measured at 3 staged of life, contributes to mortality risk.
A cohort of employed Scottish men (n = 5567) provided their fathers' occupation and their own first and current occupations, from which social class in childhood, at labor-market entry, and at screening (1970 to 1973) was determined. Relative rates of mortality and relative indices of inequality were calculated from 21 years of follow-up.
Mortality risk was similar at each stage of life, with men in the higher social classes having the lowest risk. Social class at screening produced the greatest relative indices of inequality.
The widening of inequalities in mortality in adulthood suggests the importance of the accumulation of poor socioeconomic circumstances throughout life.
本研究探讨了在人生三个阶段所衡量的社会阶层如何影响死亡风险。
一组受雇的苏格兰男性（n = 5567）提供了他们父亲的职业以及他们自己最初和当前的职业，据此确定童年时期、进入劳动力市场时以及筛查时（1970年至1973年）的社会阶层。通过21年的随访计算死亡率相对率和不平等相对指数。
在人生的每个阶段，死亡风险相似，社会阶层较高的男性风险最低。筛查时的社会阶层产生的不平等相对指数最大。
成年期死亡率不平等的加剧表明一生之中社会经济状况不佳的累积具有重要影响。
