Depression and anxiety may be significant prognostic factors after myocardial infarction (MI). Thus, we investigated depression and anxiety prevalence among older MI survivors and their impact on mortality, stroke, and recurrent MI. This population-based cohort study used the Korean National Health Insurance Service database for data concerning individuals aged 66 years who participated in the National Screening Program from 2009 to 2016. Overall, 11,721 individuals with MI history and 58,605 age- and sex-matched controls were included and followed up until 2019. The presence of depression and anxiety was assessed 2 years before and after participation in the program. Mortality and major adverse outcomes, defined as a composite outcome comprising mortality, stroke, and recurrent MI, were analyzed. Depression and anxiety prevalence among MI survivors was 20.4 % and 30.3 %, respectively. Crude odds ratios for depression and anxiety, compared with the control group, were 1.207 (1.148–1.269) and 1.078 (1.032–1.126), respectively. During the follow-up, individuals with depression, anxiety, or both showed increased hazard ratios (HRs) for mortality and major adverse outcomes; after adjustments, their HRs were 1.442 (1.182–1.759), 1.129 (0.960–1.328), and 1.498 (1.263–1.776), respectively, for mortality and 1.505 (1.289–1.758), 1.158 (1.021–1.314), and 1.530 (1.337–1.751), respectively, for major adverse outcomes. Although this was a nationwide cohort study, the MI, depression, and anxiety diagnoses were based on diagnostic codes. Higher depression and anxiety prevalence was observed among older MI survivors. Depression and anxiety occurrence correlated with increased adverse clinical outcomes after adjustments. [Display omitted] • A higher prevalence of depression and anxiety was observed in older myocardial infarction (MI) survivors. • The presence of depression and anxiety was associated with adverse clinical outcomes. • Cardiac rehabilitation models should prioritize the identification and management of depression and anxiety after MI.

Background: Although cigarette smoking is the most significant risk factor for laryngeal cancer, other risk factors might also be associated with the development of laryngeal cancer. We investigated whether underweight and type 2 diabetes are associated with laryngeal cancer in a Korean population.Methods: A total of 9,957,059 participants (≥20 years) without prior history of cancer who underwent a National Health Insurance Service health checkup in 2009 were followed up until December 31, 2018. Newly diagnosed laryngeal cancer was identified using claim data, and underweight was defined as body mass index (BMI) < 18.5 kg/m2. A Cox proportional-hazards models with multivariable adjustment were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (95% CIs).Results: During the median follow-up period of 8.3 years, 3504 cases of laryngeal cancer occurred. Underweight was associated with increased risk of laryngeal cancer after adjusting for potential confounders (HR: 1.43, 95% CI: 1.22-1.69) compared to those who were not underweight. Underweight and type 2 diabetes were synergistically associated with higher risk of laryngeal cancer (HR: 2.33, 95% CI: 1.54-3.51), compared to those without either condition. This relationship was stronger in those with an age < 65 years (HR: 3.33, 95% CI: 1.88-5.87) and alcohol consumption (HR: 2.72, 95% CI: 1.64-4.53).Conclusions: These results suggest that underweight may be a significant risk factor for laryngeal cancer and that underweight and type 2 diabetes might synergistically increase the risk of laryngeal cancer.
