Associations of Self-Care Health Behaviors With Driving Cessation Among Older Drivers.

Older adults are at risk of driving cessation as they age, which can result in negative health outcomes including loss of independence. This study aimed to investigate the associations of self-care health behaviors with the risk of driving cessation. Demographics, health and driving characteristics were captured from healthcare systems in Denver, CO, San Diego, CA, Ann Arbor, MI, Baltimore, MD and Cooperstown, NY for 2,990 adults at baseline then followed from July 2015 to January 2021 via in-person assessments and questionnaires. The follow-up accumulated a total of 7,348 person-years and 46 driving cessations, yielding an incidence rate of 0.63 per 100 person-years. Multivariable Cox proportional hazards regression was used to evaluate the relationship between self-care behaviors and driving cessation, stratified by gender, and accounting for multiple failure events and clustering by study site. Ability to participate in social roles and activities was associated with an 8% reduction in the risk of driving cessation [adjusted hazard ratio (HR): 0.92; 95% CI: 0.89, 0.94]. Increased participation in social activities and relationships is associated with driving longevity in older adults and should be targeted for interventions to maintain driving mobility.

Periodontal disease and incident prediabetes and diabetes: The Hispanic Community Health Study/Study of Latinos.

AIM: To examine whether baseline periodontal disease is independently associated with incident prediabetes and incident diabetes in Hispanics/Latinos in the United States. MATERIALS AND METHODS: This study examined 7827 individuals, 18-74 years of age without diabetes, from the Hispanic Community Health Study/Study of Latinos. Participants received a full-mouth periodontal examination at baseline (2008-2011), and the disease was classified using the Centers for Disease Control and Prevention/American Academy of Periodontology case definitions. At Visit 2 (2014-2017), incident prediabetes and diabetes were assessed using multiple standard procedures including blood tests. Multivariable survey Poisson regressions estimated the rate ratio (RR) and 95% confidence intervals (CIs) of incident prediabetes and incident diabetes associated with periodontal disease severity. RESULTS: Among the individuals without prediabetes or diabetes at baseline, 38.8% (n = 1553) had developed prediabetes and 2.2% (n = 87) had developed diabetes after 6 years. Nineteen percent (n = 727) of individuals with prediabetes at baseline developed diabetes after 6 years. Adjusting for all potential confounders, no significant association was found between periodontal disease severity and either incident prediabetes (RR: 0.93; 95% CI: 0.82-1.06) or incident diabetes (RR: 0.99; 95% CI: 0.80-1.22). CONCLUSIONS: Our findings suggest that among a diverse cohort of Hispanic/Latino individuals living in the United States, there was no association between periodontal disease severity and the development of either prediabetes or diabetes during a 6-year follow-up period.

The Association of Pain Levels and Low Physical Activity among Older Women.

There is an integral research gap regarding whether there is a relationship between pain levels and low physical activity among older women. This is a secondary analysis of a longitudinal cohort study, the Women's Health and Aging Study (WHAS) II. Our analyses included 436 community-dwelling women between the ages of 70 and 79, who were followed for 10.5 years. We employed marginal structural modeling, which controls for time-dependent confounding, with the aim of assessing the potential direct association between pain levels and low physical activity and assess a graded relationship. Compared to women with no pain, those with widespread pain were nearly half as likely to be moderately active versus low active (aOR: 0.46, 95% confidence interval (CI): 0.22, 0.96). A graded association was observed across the four pain levels (no pain or mild pain, other pain, moderate or severe lower extremity pain, and widespread pain) on low physical activity. Our findings indicate that reducing chronic widespread pain in older women may increase moderate physical activity, and therefore reduce the downstream health risks of low physical activity, including morbidity and mortality risk.
