Periodontal conditions and associated factors among adults and the elderly: findings from the first National Oral Health Survey in Uruguay

The aims of this study were to assess the prevalence of periodontal conditions in the Uruguayan adult and elderly population and its association with socioeconomic and behavioral characteristics. Data from adults (35-44, n = 358) and elderly (65-74, n = 411) who participated in the first National Oral Health Survey, Uruguay, 2011, were used. The survey included a household questionnaire addressing socioeconomic characteristics, and tobacco use. Bleeding on probing (BOP), periodontal pockets (CPI) and clinical attachment loss (CAL) were measured by clinical examination. A multivariable analysis was carried out. Considering both age groups, the prevalence of mild/severe periodontal disease was 21.8% and 9.12% for severe periodontal disease. Adjusted analyses revealed an association between high education and all outcomes. Attendance at dental services was negatively associated with BOP and mild to severe periodontitis. Periodontal outcomes were higher in disadvantaged socioeconomic groups. Tobacco consumption has a strong association with periodontal disease in the elderly.O objetivo do estudo foi determinar a prevalencia da doenca periodontal em adultos e idosos uruguaios e sua associacao com fatores comportamentais e socioeconomicos. Foram utilizados dados de adultos (35-44, n = 358) e de idosos (65-74, n = 411) participantes da primeira Pesquisa Nacional de Saude Bucal, no Uruguai, em 2011. A pesquisa incluiu um questionario sobre fatores de risco, incluindo fumo. Sangramento ao sandagem bolsa periodontal (IPC) e perda de insercao (PIP) foram avaliados por meio de exame clinico. Considerando-se as duas idades, a prevalencia da doenca moderada/grave foi de 21,8% e 9,12%. Na analise multivariada, foi observada associacao entre a educacao de nivel universitario e todas as variaveis de resposta. O atendimento odontologico foi negativamente associado com a doenca periodontal moderada e grave. A prevalencia foi maior no grupo com menor nivel socioeconomico. Dentre os idosos, o tabagismo foi fortemente associado a doenca periodontal.

Visuospatial Reasoning Trajectories and Death in a Study of the Oldest Old: A Formal Evaluation of Their Association:

Objectives: To model trajectories of visuospatial reasoning measured using Kohs Block Design test under realistic missing data assumptions and evaluate their association with hazard of death. Methods: A joint longitudinal-survival model was used to estimate trajectories of visuospatial reasoning under a missing not at random assumption of participants from the Origins of Variance in the Old–Old: Octogenarian Twins study. Sensitivity analyses to missing data assumptions were conducted. Results: Visuospatial reasoning declined at constant rate. Baseline age, dementia status, education, and history of stroke were associated with visuospatial reasoning performance, but only dementia was associated with its rate of decline. Importantly, our results demonstrated an association between poorer visuospatial reasoning and increased hazard of death. Baseline age and sex were associated with risk of death. Discussion: We confirmed an association between visuospatial reasoning and death under plausible missing data assumptions.
