What factors can be protective for both self-rated oral health and general health?

The aim of this study was to analyze if the same protective factors are significant for both self-rated health and oral health. It was hypothesized that these factors should be the same. The material is based on a population sample of 17 113 women and men aged 18-84 years in one county in central Sweden.The response rate was 61%. The data were collected through a postal questionnaire "Life and Health" in 2008. The questionnaire comprised of 149 questions and was divided into a number of areas, e.g. socioeconomic conditions, quality of life, social relations, lifestyle, and health. To analyze the strength of the protective factors whilst taking into account the relationships between the various independent variables, multivariate analyses were conducted using binary multiple logistic regression. The outcome measures with the strongest association to general health is belonging to the age group 18-34 years, positive faith in the future, good sleeping pattern and to be employed/self-employed/retired. The outcomes with the strongest association to oral health are good finances, belonging to the age group 18-34 years, to be born in Sweden and positive faith in the future. Conclusions. This study shows that, in general, the same protective factors are significant for both self-rated health and self-rated oral health, making it possible to use the same approach to strengthen both general health and oral health. One important outcome, not often considered, is having positive faith in the future. It is a task for the health care system to strengthen people's faith in the future, partly through a very high quality care when needed, but also through active health promotion that increases the chances of a healthy life, both from a public health perspective as from an oral health perspective.
