Psychosocial factors and self-reported transitions in oral and general health.

Psychosocial factors may explain variance in health beyond conventional indicators, such as behaviours. This study aimed to examine changes in health associated with perceived stress, social support, and self-efficacy, controlling for sociodemographic characteristics and health behaviour. A random sample of 45- to 54-yr-old subjects was surveyed in 2004-2005, with a follow-up 2 yr later. The outcomes were self-reported changes in oral and general health. Explanatory variables included stress, social support, and perceived health competence with covariates of income, gender, dentition status, toothbrushing, and smoking. Responses were collected from 986 persons (response = 44.4%). At the 2-yr follow-up, 25.6% reported worsening in oral health and 15.3% reported worsening in general health. Prevalence ratios (PR) from adjusted log-binomial regression showed an association between worsening oral health and higher perceived health competence (PR = 0.75, 95% CI: 0.57-0.99), and worsening general health was associated with perceived health competence (PR = 0.82, 95% CI: 0.72-0.94) and stress (PR = 1.17, 95% CI: 1.03-1.32). Worsening oral and general health were seen for male subjects (PR = 1.33, 95% CI: 1.06-1.68 and PR = 1.14, 95% CI: 1.01-1.29) and low income (PR = 1.40, 95% CI: 1.04-1.89 and PR = 1.20, 95% CI: 1.03-1.40). Health-related self-efficacy representing psychosocial resilience was associated with oral and general health, while stress was associated with general health. Psychosocial factors were independent predictors of change in health after controlling for sociodemographic characteristics and health behaviours.
