Dietary Glutamine and Glutamate in Relation to Cardiovascular Disease Incidence and Mortality in the United States Men and Women with Diabetes Mellitus.

ABSTRACT:

Background

Evidence regarding the potential health effects of dietary amino acids glutamine and glutamate among individuals with type 2 diabetes (T2D) is limited.

Objectives

The aim was to examine dietary glutamine and glutamate in relation to subsequent risk of cardiovascular disease (CVD) and mortality among individuals with T2D.

Methods

We prospectively followed 15,040 men and women with T2D at baseline or diagnosed during follow-up (Nurses' Health Study: 1980-2014 and Health Professionals Follow-Up Study: 1986-2018). Diet was repeatedly assessed using validated food frequency questionnaires every 2-4 y. Associations of energy-adjusted glutamine and glutamate intake, as well as their ratio, with CVD risk and mortality, were assessed using Cox proportional-hazards models with adjustments for demographics, dietary and lifestyle factors, and medical history.

Results

During 196,955 and 225,371 person-years of follow-up in participants with T2D, there were 2927 incident CVD cases and 4898 deaths, respectively. Higher intake of glutamine was associated with lower risk of CVD incidence, CVD mortality, and total mortality: comparing extreme quintiles, the hazard ratios (HRs) (95% confidence intervals [CIs]) were 0.88 (0.77, 0.99), 0.78 (0.65, 0.92), and 0.84 (0.76, 0.92), respectively (all P-trend < 0.05). In contrast, higher intake of glutamate was associated with a higher risk of CVD incidence, CVD mortality, and total mortality; the HRs were 1.30 (1.15, 1.46), 1.46 (1.24, 1.72), and 1.20 (1.09, 1.32), respectively (all P-trend < 0.05). Furthermore, comparing extreme quintiles, a higher dietary glutamine-to-glutamate ratio was associated with a lower risk of CVD incidence (0.84 [0.75, 0.95]), CVD mortality (0.66 [0.57, 0.77]), and total mortality (0.82 [0.75, 0.90]). In addition, compared with participants with stable or decreased consumption of glutamine-to-glutamate ratio from prediabetes to postdiabetes diagnosis, those who increased the ratio had a 17% (5%, 27%) lower CVD mortality.

Conclusions

In adults with T2D, dietary glutamine was associated with a lower risk of CVD incidence and mortality, whereas the opposite was observed for glutamate intake.

Project description:RationaleThe evidence regarding the potential health benefits of nut consumption among individuals with type 2 diabetes mellitus is limited.ObjectiveTo examine intake of total and specific types of nuts, including tree nuts and peanuts, in relation to subsequent risk of cardiovascular disease (CVD), including coronary heart disease and stroke, and all-cause and cause-specific mortality among individuals with diabetes mellitus.Methods and resultsThis prospective analysis included 16 217 men and women with diabetes mellitus at baseline or diagnosed during follow-up (Nurses' Health Study: 1980-2014, Health Professionals Follow-Up Study: 1986-2014). Nut consumption was assessed using a validated food frequency questionnaire and updated every 2 to 4 years. During 223 682 and 254 923 person-years of follow-up, there were 3336 incident CVD cases and 5682 deaths, respectively. Higher total nut consumption was associated with a lower risk of CVD incidence and mortality. The multivariate-adjusted hazard ratios (95% CIs) for participants who consumed 5 or more servings of total nuts per week (1 serving=28 g), compared with those who consumed <1 serving per month, were 0.83 (0.71-0.98; P trend=0.01) for total CVD incidence, 0.80 (0.67-0.96; P trend=0.005) for coronary heart disease incidence, 0.66 (0.52-0.84; P trend <0.001) for CVD mortality, and 0.69 (0.61-0.77; P trend <0.001) for all-cause mortality. Total nut consumption was not significantly associated with risk of stroke incidence or cancer mortality. For specific types of nuts, higher tree nut consumption was associated with lower risk of total CVD, coronary heart disease incidence, and mortality because of CVD, cancer, and all causes, whereas peanut consumption was associated with lower all-cause mortality only (all P trend <0.001). In addition, compared with participants who did not change the consumption of total nuts from pre- to post-diabetes mellitus diagnosis, participants who increased consumption of total nuts after diabetes mellitus diagnosis had an 11% lower risk of CVD, a 15% lower coronary heart disease risk, a 25% lower CVD mortality, and a 27% lower all-cause mortality. The associations persisted in subgroup analyses stratified by sex/cohort, body mass index at diabetes mellitus diagnosis, smoking status, diabetes mellitus duration, nut consumption before diabetes mellitus diagnosis, or diet quality.ConclusionsHigher consumption of nuts, especially tree nuts, is associated with lower CVD incidence and mortality among participants with diabetes mellitus. These data provide novel evidence that supports the recommendation of incorporating nuts into healthy dietary patterns for the prevention of CVD complications and premature deaths among individuals with diabetes mellitus.

Project description:BackgroundPrevious studies showed a higher incidence of lung cancer among young women than among young men in the United States. Whether this pattern has continued in contemporary birth cohorts and, if so, whether it can be fully explained by sex differences in smoking behaviors are unknown.MethodsWe examined the nationwide population-based incidence of lung cancer according to sex, race or ethnic group, age group (30 to 34, 35 to 39, 40 to 44, 45 to 49, and 50 to 54 years), year of birth (1945 to 1980), and calendar period of diagnosis (1995-1999, 2000-2004, 2005-2009, and 2010-2014), and we calculated female-to-male incidence rate ratios. We also examined the prevalence of cigarette smoking, using data from the National Health Interview Survey from 1970 to 2016.ResultsOver the past two decades, the age-specific incidence of lung cancer has generally decreased among both men and women 30 to 54 years of age in all races and ethnic groups, but the declines among men have been steeper. Consequently, among non-Hispanic whites, the female-to-male incidence rate ratios increased, exceeding 1.0 in the age groups of 30 to 34, 35 to 39, 40 to 44, and 45 to 49 years. For example, the female-to-male incidence rate ratio among whites 40 to 44 years of age increased from 0.88 (95% confidence interval [CI], 0.84 to 0.92) during the 1995-1999 period to 1.17 (95% CI, 1.11 to 1.23) during the 2010-2014 period. The crossover in sex-specific rates occurred among non-Hispanic whites born since 1965. Sex-specific incidence rates converged among non-Hispanic blacks, Hispanics, and non-Hispanic Asians and Pacific Islanders but crossed over from a higher incidence among men to a higher incidence among women only among Hispanics. The prevalence of cigarette smoking among women born since 1965 has approached, but generally not exceeded, the prevalence among men.ConclusionsThe patterns of historically higher incidence rates of lung cancer among men than among women have reversed among non-Hispanic whites and Hispanics born since the mid-1960s, and they are not fully explained by sex differences in smoking behaviors. Future studies are needed to identify reasons for the higher incidence of lung cancer among young women. (Funded by the American Cancer Society.).

Project description:PurposeTo support trials testing lifestyle interventions for lower urinary tract symptoms, often a consequence of benign prostatic hyperplasia, we estimated the incidence and progression rates of lower urinary tract symptoms in United States men unselected for benign prostatic hyperplasia.Materials and methodsWe studied men in the HPFS (Health Professionals Follow-Up Study) whom we asked to report periodically by mailed survey whether they had undergone surgery or used medications for lower urinary tract symptoms and to complete the International Prostate Symptom Score survey. For incidence we included 25,879 men with an International Prostate Symptom Score of 0 to 7 and no surgery history who were followed from 1992 to 2008. Incident moderate or worse lower urinary tract symptoms (6,058) were defined as an International Prostate Symptom Score of 15 or greater, surgery, or medication use. Modest or worse lower urinary tract symptoms were similarly defined but with an International Prostate Symptom Score of 8 or greater (11,352). For progression we included 9,628 men with an International Prostate Symptom Score of 8 to 14 and no surgery who were followed from when they first reported an International Prostate Symptom Score of 8 to 14 until 2008. Progression to severe lower urinary tract symptoms (2,557) was defined as an International Prostate Symptom Score of 20 or greater, surgery, or medication use. We estimated age specific and age standardized rates.ResultsIncidence and progression rates increased with age (p trend <0.0001), and progression rates were higher than incidence rates. The age standardized rates were incidence of moderate to worse lower urinary tract symptoms 18.5, incidence of modest or worse lower urinary tract symptoms 40.5 and progression to severe lower urinary tract symptoms 44.9 per 1,000 man-years.ConclusionsThe incidence and progression rates of lower urinary tract symptoms are high and increase steeply as men age. These rates may be used for planning adequately powered trials to test lifestyle interventions for lower urinary tract symptoms well before surgical or pharmacological treatment is indicated.
