Monitoring inequalities in self-rated health over 36 years among Finnish women and men

Abstract

Abstract Background Health inequalities across countries and populations are well established, but little is known about their long-term trends and even less about factors shaping the trends. We examined the magnitude of absolute and relative educational inequalities in self-rated health over 36 years among adult Finns, considering individual covariates and macro-economic fluctuations. Methods Data were derived from representative annual surveys in 1979-2014 among men and women and covered ages 25-64. Nine periods were used (n = 8870-14235). Our health outcome was less-than-good self-rated health and our socioeconomic indicator was completed years of education as a continuous variable. Nine time-variant sociodemographic and health-related covariates were included. Educational inequalities in self-rated health were examined by relative index of inequality (RII) and slope index of inequality (SII). Results Linear trends suggested stable overall development in both relative and absolute health equalities during 36 years. Period specific analyses showed that among men relative and absolute inequalities narrowed immediately after economic recession in Finland in 1993-94, and among women, inequalities narrowed during global financial crisis in 2008-09. Adjusting for covariates reduced the magnitude of inequalities throughout the nine periods, but affected little the period specific patterning of health inequalities. Conclusions Educational inequalities in self-rated health persisted during 36 years in Finland. While among men and women health inequalities narrowed during and after recessions, they widened soon back to the pre-recession level. The perseverance calls for powerful measures to tackle health inequalities, such as preventing unhealthy behaviours, obesity and unemployment in particular among the lower educated. Key messages Health inequalities have persisted in Finland over 36 years, with unhealthy behaviors and unemployment affecting their magnitude. Health inequalities narrowed during economic recessions, but widened soon back to pre-recession level.
