Sense of coherence and health in women: a 25-year follow-up study.

backgroundHealth and Sense of Coherence (SOC) has been shown to be intertwined and argued to have a reciprocal relationship. The theory of SOC implies relatively stable scores during adulthood, however there are few longitudinal studies on the association between SOC and mental and somatic health. The main aim of the present study was to examine how SOC and self-rated health (SRH) are related during 25 years of follow-up.

methodsUsing paper questionnaires distributed by postal services, 415 mothers were followed from childbirth and 25 years prospectively. SOC was measured at three, 12 and 25 years after inclusion. Self-reports on health status were obtained at the 25-year follow-up. The association between SOC and self-reported health as well as the effect of sociodemographic factors and experience of stressful life events was assessed through regression models.

resultsSOC scores increased between three and 12 years after inclusion, and slightly decreased at the 25-year follow-up. Women of good health had a higher SOC-score at all three measurements compared to women of poor health. Multiple logistic regression showed that the likelihood of reporting good health increased with the number of times the women had reported SOC-scores above the 75th percentile. Moreover, women who had not been through a divorce were close to 60% more likely to report good health compared to women who had been through a divorce, whereas women not reporting stressful life events during the past two years were more than twice as likely to report good health. Symptoms below cut-off for postpartum depression and not having been through a divorce were associated with SOC scores above the 75th percentile.

conclusionThis 25-year follow-up study of a cohort of women reports good stability of SOC assessments in the vast majority of women. There was a stronger and more stable SOC in women with better health. The findings are in line with other studies on the predictive value of SOC and self-perceived health.
