RESUMO
The objective was to investigate the role of employment in the 11-y changes of clinically determined oral health. We used data from the longitudinal Health 2011 Survey, including reinvited subjects from the Health 2000 Survey. Data were gathered by clinical oral examinations, interviews, and questionnaires of those aged 30 to 63 y ( n = 1,031) in 2000. Exposures were change in employment from baseline to follow-up and length of unemployment. Outcomes measures were the numbers of missing teeth, sound teeth, filled teeth, decayed teeth, and teeth with periodontal pockets (≥4 mm and ≥6 mm). Separate mixed-effects and conventional negative binomial regression models were fitted for each oral health outcome. Demographic, socioeconomic, and oral health-related behaviors were added as covariates to the analyses. The findings showed that unemployment was inconsistently associated with poorer clinically determined oral health over 11 y. These effects were attributed to income and education and, to a lesser extent, to oral health-related behaviors. The length of unemployment was also inconsistently associated with oral health. The study concluded that one socioeconomic factor, unemployment, had a partial impact on oral health. Knowledge Transfer Statement: The findings of this study can help clinicians and oral health policy makers to reorient oral health services toward those who are unemployed as a risk group for poor oral health. The research highlights the role of employment in the longitudinal changes of clinically determined oral health, taking into consideration other socioeconomic factors. The study concluded that unemployment seemed to have a role in social inequalities of oral health.
