Objectives: To examine the association of alcohol consumption measured at different points in time and periodontitis at 20 years follow-up and to investigate whether long-term alcohol consumption is related to periodontitis in old age. Design: Participants aged 65 years or older in 2003, from the longitudinal study Copenhagen City Heart Study (CCHS), were invited to participate in the Copenhagen Oral Health Senior Study. Methods: Clinical periodontal attachment loss was calculated to determine the progress of periodontitis. Alcohol consumption was measured at CCHS follow-ups in 1981-1983, 1991-1994 and 2001-2003, using a standard questionnaire. Alcohol consumption was defined as light, moderate and heavy drinking and used individually for each follow-up. The three follow-ups were summarized into long-term alcohol consumption. Logistic regression analysis was used to estimate the relation between alcohol consumption measured at different points in time and periodontitis and to assess the effect of long-term alcohol consumption on periodontitis. Results: The results show that heavy drinkers in 1981-1983 had a higher odds ratio for having periodontitis compared to light drinkers (OR = 4.64 95% CI = [1.1; 19.42]). Conclusion: Early consumption of alcohol may increase the odds of having periodontitis 20 years later. There is a need for further studies including larger populations to investigate both alcohol consumption measured at different points in time, and long-term alcohol consumption and periodontitis progression over time.
