The effects of poverty on sleep problems in Sweden

Does relative poverty measured as low disposable household income or the presence of personal financial crisis affect health measured in terms of self-reported sleep problems? If so, is this effect modified by macroeconomic conditions or life changes such as unemployment experience, divorce or limiting illness, and it is buffered by social networks or coping behavior such as smoking? These questions are studied on a representative sample of employed people aged 20-65 who participated in the Survey of Living Conditions conducted by Statistics Sweden for the years 1980-1981 (7180 people) and 1986-1989 (13,376 people). The results reveal a conditional relationship between poverty and sleep problems. Among men it is modified, in particular, by previous experience of unemployment. Among women strong social networks buffers the effect but smoking aggravates it. Men's sleep was affected more by poverty and unemployment in the late 1980s than in the earlier period.
