Association between fasting glucose and all-cause mortality according to sex and age: a prospective cohort study.

ABSTRACT: The association of fasting glucose with the risk of death according to sex and age remains unclear, and insufficient information is available on sex- and age-specific glucose concentrations within ethnic groups. This study analyzed a sample of 12,455,361 Korean adults who participated in health examinations during 2001-2004, and were followed up until 2013. Men had 3.0 mg/dL (0.167 mmol/L) higher mean glucose concentrations than women (94.7 vs. 91.7 mg/dL), although women over 73 years had higher levels. For glucose levels of 100-199 mg/dL, each 18 mg/dL (1 mmol/L) increase in fasting glucose increased mortality by 13% (HR = 1.13, [95% CI 1.12 to 1.13], p < 0.001). In individuals with fasting glucose levels of 100-125 mg/dL, each 18 mg/dL increase in fasting glucose was associated with a 30% increase in the risk for mortality (1.30, [1.18 to 1.43]) in those aged 18-34 years, a 32% increase (1.32, [1.26 to 1.39]) in those aged 35-44 years, and a 10% increase (1.10, [1.02 to 1.19]) in those aged 75-99 years. The fasting glucose levels associated with the lowest mortality were 80-94 mg/dL regardless of sex and age. Prediabetes (100-125 mg/dL) was associated with higher mortality. The associations of hyperglycemia with mortality were stronger at younger ages.

Project description:BackgroundThe relationship between inflammatory response, fish consumption, and mortality risk in older individuals is unclear. We investigated whether C-reactive protein (CRP) levels ≥ 0.1 mg/dL, fish intake, and inflammatory responses are associated with all-cause mortality risk in older adults.MethodsThis prospective cohort study included older adults aged 85-89 years from the Kawasaki Aging and Wellbeing Project, who did not require daily care. Cohort was recruited from March 2017 to December 2018 (follow-up ended on December 31, 2021). Dietary assessment was conducted using the Brief Self-Administered Diet History Questionnaire. Multivariate Cox proportional hazards regression was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for all-cause mortality in the CRP ≥ 0.1 mg/dL group; the CRP < 0.1 mg/dL group was used for reference. Within CRP ≥ 0.1 and < 0.1 mg/dL groups, participants were categorized into tertiles of fish intake. HRs and 95% CIs for all-cause mortality in the other groups were estimated using the lower tertile group as a reference.ResultsThe study included 996 participants (mean [standard deviation] age, 86.5 [1.37] years; 497 [49.9%] women) with a median CRP level of 0.08 (interquartile range [IQR] = 0.04-0.16). There were 162 deaths during 4,161 person-years of observation; the multivariable-adjusted HR for all-cause mortality in the CRP ≥ 0.1 mg/dL group was 1.86 (95% CI, 1.32-2.62); P < 0.001. In 577 individuals with median (IQR) fish intake of 39.3 g/1000 kcal (23.6-57.6) and CRP level of < 0.1 mg/dL, the multivariable-adjusted HR for all-cause mortality in the higher tertile group of fish intake was 1.15 (0.67-1.97); P = 0.59, non-linear P = 0.84. In 419 individuals with median (IQR) fish intake of 40.7 g/1000 kcal (25.0-60.1) and CRP level of ≥ 0.1 mg/dL, the multivariate-adjusted HR for all-cause mortality in the higher tertile group of fish intake was 0.49 (0.26-0.92); P = 0.026, non-linear P = 0.38, P-value for interaction = 0.040.ConclusionsA negative association between fish intake and all-cause mortality was seen in older adults with elevated CRP levels, which is a mortality risk factor. While the results may be limited owing to stringent methods ensuring impartiality, they offer valuable insights for future research.Trial registrationUMIN000026053. Registered February 24, 2017.

Project description:ObjectiveTo investigate the association of spontaneous abortion with the risk of all cause and cause specific premature mortality (death before the age of 70).DesignProspective cohort study.SettingThe Nurses' Health Study II (1993-2017), United States.Participants101 681 ever gravid female nurses participating in the Nurses' Health Study II.Main outcomes measuresLifetime occurrence of spontaneous abortion in pregnancies lasting less than 6 months, determined by biennial questionnaires. Hazard ratios and 95% confidence intervals for all cause and cause specific premature death according to the occurrence of spontaneous abortion, estimated with time dependent Cox proportional hazards models.ResultsDuring 24 years of follow-up, 2936 premature deaths were recorded, including 1346 deaths from cancer and 269 from cardiovascular disease. Crude all cause mortality rates were comparable for women with and without a history of spontaneous abortion (1.24 per 1000 person years in both groups) but were higher for women experiencing three or more spontaneous abortions (1.47 per 1000 person years) and for women reporting their first spontaneous abortion before the age of 24 (1.69 per 1000 person years). The corresponding age adjusted hazard ratios for all cause premature death during follow-up were 1.02 (95% confidence interval 0.94 to 1.11), 1.39 (1.03 to 1.86), and 1.27 (1.11 to 1.46), respectively. After adjusting for confounding factors and updated dietary and lifestyle factors, the occurrence of spontaneous abortion was associated with a hazard ratio of 1.19 (95% confidence interval 1.08 to 1.30) for premature mortality during follow-up. The association was stronger for recurrent spontaneous abortions (hazard ratio 1.59, 95% confidence interval 1.17 to 2.15 for three or more spontaneous abortions; 1.23, 1.00 to 1.50 for two; and 1.16, 1.05 to 1.28 for one compared with none), and for spontaneous abortions occurring early in a woman's reproductive life (1.32, 1.14 to 1.53 for age ≤23; 1.16, 1.01 to 1.33 for ages 24-29; and 1.12, 0.98 to 1.28 for age ≥30 compared with none). When cause specific mortality was evaluated, the association of spontaneous abortion with premature death was strongest for deaths from cardiovascular disease (1.48, 1.09 to 1.99). Spontaneous abortion was not related to premature death from cancer (1.08, 0.94 to 1.24).ConclusionsSpontaneous abortion was associated with an increased risk of premature mortality, particularly death from cardiovascular disease.

Project description:Background Dietary recommendations regarding protein intake have been focused on the amount of protein. However, such recommendations without considering specific protein sources may be simplistic and insufficient. Methods and Results We included 102 521 postmenopausal women enrolled in the Women's Health Initiative between 1993 and 1998, and followed them through February 2017. During 1 876 205 person-years of follow-up, 25 976 deaths occurred. Comparing the highest with the lowest quintile, plant protein intake was inversely associated with all-cause mortality (hazard ratio [HR], 0.91 [0.86, 0.96]), cardiovascular disease mortality (HR, 0.88 [0.79, 0.97]), and dementia mortality (HR, 0.79 [0.67, 0.94]). Among major protein sources, comparing the highest with the lowest quintile of consumption, processed red meat (HR, 1.06 [1.01, 1.10]) or eggs (HR, 1.14 [1.10, 1.19]) was associated with higher risk of all-cause mortality. Unprocessed red meat (HR, 1.12 [1.02, 1.23]), eggs (HR, 1.24 [1.14, 1.34]), or dairy products (HR, 1.11 [1.02, 1.22]) was associated with higher risk of cardiovascular disease mortality. Egg consumption was associated with higher risk of cancer mortality (HR, 1.10 [1.02, 1.19]). Processed red meat consumption was associated with higher risk of dementia mortality (HR, 1.20 [1.05, 1.32]), while consumption of poultry (HR, 0.85 [0.75, 0.97]) or eggs (HR, 0.86 [0.75, 0.98]) was associated with lower risk of dementia mortality. In substitution analysis, substituting of animal protein with plant protein was associated with a lower risk of all-cause mortality, cardiovascular disease mortality, and dementia mortality, and substitution of total red meat, eggs, or dairy products with nuts was associated with a lower risk of all-cause mortality. Conclusions Different dietary protein sources have varying associations with all-cause mortality, cardiovascular disease mortality, and dementia mortality. Our findings support the need for consideration of protein sources in future dietary guidelines.
