Changes in Alcohol Consumption and Subsequent Risk of Type 2 Diabetes in Men
Objective -The objective of this study was to investigate the association of four-year changes in alcohol consumption with subsequent risk of type 2 diabetes. Research Design and Methods - We prospectively examined 38,031 men from the Health Professionals Follow-up Study free of diagnosed diabetes or cancer in 1990. Alcohol consumption was reported on food frequency questionnaires and updated every four years. Results - A total of 1905 cases of type 2 diabetes occurred during 428,497 person-years of follow-up. A 7.5 g/day (~half a glass) increase in alcohol consumption over four years was associated with lower diabetes risk among initial nondrinkers (multivariable hazard ratio [HR] 0.78; 95% confidence interval [CI] 0.60-1.00) and drinkers initially consumin

Toenail Selenium and Incidence of Type 2 Diabetes in U.S. Men and Women
OBJECTIVE Compelling biological pathways suggest that selenium (Se) may lower onset of type 2 diabetes mellitus (T2DM), but very few studies have evaluated this relationship, with mixed results. We examined the association between toenail Se and incidence of T2DM. RESEARCH DESIGN AND METHODS We performed prospective analyses in two separate U.S. cohorts, including 3,630 women and 3,535 men, who were free of prevalent T2DM and heart disease at baseline in 1982–1983 and 1986–1987, respectively. Toenail Se concentration was quantified using neutron activation analysis, and diabetes cases were identified by biennial questionnaires and confirmed by a detailed supplementary questionnaire. Hazard ratios of incident T2DM according to Se levels were calculated using Cox proportional hazards. RESULTS During 142,550 person-years of follow-up through 2008, 780 cases of incident T2DM occurred. After multivariable adjustment, the risk of T2DM was lower across increasing quintiles of Se, with pooled relative risks across the two cohorts of 1.0 (reference), 0.91 (95% CI 0.73–1.14), 0.78 (0.62–0.99), 0.72 (0.57–0.91), and 0.76 (0.60–0.97), respectively (P for trend = 0.01). Results were similar excluding the few individuals (4%) who used Se supplements. In semiparametric analyses, the inverse relationship between Se levels and T2DM risk appeared to be linear. CONCLUSIONS At dietary levels of intake, individuals with higher toenail Se levels are at lower risk for T2DM. Further research is required to determine whether varying results in this study versus prior trials relate to differences in dose, source, statistical power, residual confounding factors, or underlying population risk
Diet-Quality Scores and the Risk of Type 2 Diabetes in Men
Objective: To 1) compare associations of diet-quality scores, which were inversely associated with cardiovascular disease, with incident type 2 diabetes and 2) test for differences in absolute-risk reduction across various strata. Research Design and Methods: Men from the Health Professionals Follow-Up Study, who were initially free of type 2 diabetes, cardiovascular disease, or cancer (n = 41,615), were followed for years. The Healthy Eating Index (HEI) 2005, the alternative HEI (aHEI) the Recommended Food Score, the alternative Mediterranean Diet (aMED) Score, and the Dietary Approaches to Stop Hypertension (DASH) Score were calculated from food-frequency questionnaires. Cox proportional hazard models with time-varying covariates were used to assess risk by quintiles and continuous intervals. Results: There were 2,795 incident cases of type 2 diabetes. After multivariate adjustment, the aHEI, aMED, and DASH scores were significantly associated with reduced risk. A 1-SD increase was associated with 9–13% reduced risk (P < 0.01), and the DASH score was associated with lower risk independent of other scores. These scores were associated with lower absolute risk among those who were overweight or obese compared with normal weight (P for interaction < 0.01). Conclusions: Several diet-quality scores were associated with a lower risk of type 2 diabetes and reflect a common dietary pattern characterized by high intakes of plant-based foods such as whole grains; moderate alcohol; and low intakes of red and processed meat, sodium, sugar-sweetened beverages, and trans fat. High-quality diets may yield the greatest reduction in diabetes cases when followed by those with a high BMI
Healthy Lifestyle in the Primordial Prevention of Cardiovascular Disease Among Young Women
AbstractBackgroundOverall mortality rates from coronary heart disease (CHD) in the United States have declined in recent decades, but the rate has plateaued among younger women. The potential for further reductions in mortality rates among young women through changes in lifestyle is unknown.ObjectivesThe aim of this study was to estimate the proportion of CHD cases and clinical cardiovascular disease (CVD) risk factors among young women that might be attributable to poor adherence to a healthy lifestyle.MethodsA prospective analysis was conducted among 88,940 women ages 27 to 44 years at baseline in the Nurses’ Health Study II who were followed from 1991 to 2011. Lifestyle factors were updated repeatedly by questionnaire. A healthy lifestyle was defined as not smoking, a normal body mass index, physical activity ≥ 2.5 h/week, television viewing ≤ 7 h/week, diet in the top 40% of the Alternative Healthy Eating Index–2010, and 0.1 to 14.9 g/day of alcohol. To estimate the proportion of CHD and clinical CVD risk factors (diabetes, hypertension, and hypercholesterolemia) that could be attributed to poor adherence to a healthy lifestyle, we calculated the population-attributable risk percent.ResultsDuring 20 years of follow-up, we documented 456 incident CHD cases. In multivariable-adjusted models, nonsmoking, a healthy body mass index, exercise, and a healthy diet were independently and significantly associated with lower CHD risk. Compared with women with no healthy lifestyle factors, the hazard ratio for CHD for women with 6 lifestyle factors was 0.08 (95% confidence interval: 0.03 to 0.22). Approximately 73% (95% confidence interval: 39% to 89%) of CHD cases were attributable to poor adherence to a healthy lifestyle. Similarly, 46% (95% confidence interval: 43% to 49%) of clinical CVD risk factor cases were attributable to a poor lifestyle.ConclusionsPrimordial prevention through maintenance of a healthy lifestyle among young women may substantially lower the burden of CVD

Plasma Levels of Fetuin‐A and Risk of Coronary Heart Disease in US Women: The Nurses' Health Study
Background: Fetuin‐A may be involved in the etiology of coronary heart disease (CHD) through opposing pathways (ie, promoting insulin resistance and inhibiting ectopic calcification). We aimed to explicitly examine whether systemic inflammation, a factor leading to elevated vascular calcification, may modify the association between fetuin‐A and CHD risk. Method and Results During 16 years of follow‐up (1990–2006), we prospectively identified and confirmed 466 incident fatal or nonfatal CHD case in the Nurses' Health Study. For each case, 1 healthy control was selected using risk‐set sampling from 26 245 eligible participants. Cases and controls were matched for age, smoking status, fasting status, and date of blood draw. After multivariate adjustment for lifestyle factors, body mass index, diet, and blood lipids, fetuin‐A levels were not associated with CHD risk in the whole population: odds ratio (OR) (95% CI) comparing extreme quintiles of fetuin‐A was 0.79 (0.44 to 1.40). However, a significant inverse association was observed among participants with higher C‐reactive protein levels (Pinteraction=0.04). The OR (95% CI) comparing highest versus lowest quintiles of fetuin‐A was 0.50 (0.26 to 0.97; Ptrend=0.004) when C‐reactive protein levels were above population median (0.20 mg/dL), whereas among the remainder of the participants, the corresponding OR (95% CI) was 1.09 (0.58 to 2.05; Ptrend=0.75). Conclusions: In this population of US women, fetuin‐A levels were associated with lower CHD risk when C‐reactive protein levels were high, but null association was observed among participants with lower C‐reactive protein levels. This divergent pattern of association needs replication in future studies

Migraine and risk of cardiovascular disease in women: Prospective cohort study
Objective To evaluate the association between migraine and incident cardiovascular disease and cardiovascular mortality in women. Design Prospective cohort study among Nurses’ Health Study II participants, with follow-up from 1989 and through June 2011. Setting Cohort of female nurses in United States. Participants 115 541 women aged 25-42 years at baseline and free of angina and cardiovascular disease. Cumulative follow-up rates were more than 90%. Main outcome measures The primary outcome of the study was major cardiovascular disease, a combined endpoint of myocardial infarction, stroke, or fatal cardiovascular disease. Secondary outcome measures included individual endpoints of myocardial infarction, stroke, angina/coronary revascularization procedures, and cardiovascular mortality. Results 17 531 (15.2%) women reported a physician’s diagnosis of migraine. Over 20 years of follow-up, 1329 major cardiovascular disease events occurred and 223 women died from cardiovascular disease. After adjustment for potential confounding factors, migraine was associated with an increased risk for major cardiovascular disease (hazard ratio 1.50, 95% confidence interval 1.33 to 1.69), myocardial infarction (1.39, 1.18 to 1.64), stroke (1.62, 1.37 to 1.92), and angina/coronary revascularization procedures (1.73, 1.29 to 2.32), compared with women without migraine. Furthermore, migraine was associated with a significantly increased risk for cardiovascular disease mortality (hazard ratio 1.37, 1.02 to 1.83). Associations were similar across subgroups of women, including by age (<50/≥50), smoking status (current/past/never), hypertension (yes/no), postmenopausal hormone therapy (current/not current), and oral contraceptive use (current/not current). Conclusions Results of this large, prospective cohort study in women with more than 20 years of follow-up indicate a consistent link between migraine and cardiovascular disease events, including cardiovascular mortality. Women with migraine should be evaluated for their vascular risk. Future targeted research is warranted to identify preventive strategies to reduce the risk of future cardiovascular disease among patients with migraine
Association between intake of fruits and vegetables by pesticide residue status and coronary heart disease risk
Background: Fruit and vegetable (FV) intake is recommended for the prevention of coronary heart disease
(CHD). FVs are also an important source of exposure to pesticide residues. Whether the relations of FV intake
with CHD differ according to pesticide residue status is unknown.
Objective: To examine the associations of high- and low-pesticide-residue FVs with the risk of CHD.
Methods: We followed 145,789 women and 24,353 men free of cardiovascular disease and cancer (excluding
non-melanoma skin cancer) at baseline and participating in three ongoing prospective cohorts: the Nurses'
Health Study (NHS: 1998–2012), the NHS-II (1999–2013), and the Health Professionals Follow-up Study (HPFS:
1998–2012). FV intake was assessed via food frequency questionnaires. We categorized FVs as having high- or
low-pesticide-residues using a validated method based on pesticide surveillance data from the US Department of
Agriculture. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95%
confidence intervals (95%CI) of CHD in relation to high- and low-pesticide-residue FV intake.
Results: A total of 3707 incident CHD events were identified during 2,241,977 person-years of follow-up. In
multivariable-adjusted models, a greater intake of low-pesticide-residue FVs was associated with a lower risk of
CHD whereas high-pesticide-residue FV intake was unrelated to CHD risk. Specifically, compared with individuals
consuming<1 serving/day of low-pesticide-residue FVs, those consuming ≥4 servings/day had 20%
(95CI: 4%, 33%) lower risk of CHD. The corresponding HR (comparing ≥4 servings/day to<1 serving/day) for
high-pesticide-residue FV intake and CHD was 0.97 (95%CI: 0.72, 1.30).
Conclusions: Our data suggested exposure to pesticide residues through FV intake may modify some cardiovascular
benefits of FV consumption. Further confirmation of these findings, especially using biomarkers for assessment of pesticide exposure, is neededThis work was supported by research grants [U01 HL145386, UM1

Lipoprotein-Associated Phospholipase A2 Activity and Incident Coronary Heart Disease Among Men and Women With Type 2 Diabetes
Bachelors, Divorcees, and Widowers: Does Marriage Protect Men from Type 2 Diabetes?
While research has suggested that being married may confer a health advantage, few studies to date have investigated the role of marital status in the development of type 2 diabetes. We examined whether men who are not married have increased risk of incident type 2 diabetes in the Health Professionals Follow-up Study. Men (n = 41,378) who were free of T2D in 1986, were followed for ≤22 years with biennial reports of T2D, marital status and covariates. Cox proportional hazard models were used to compare risk of incident T2D by marital status (married vs unmarried and married vs never married, divorced/separated, or widowed). There were 2,952 cases of incident T2D. Compared to married men, unmarried men had a 16% higher risk of developing T2D (95%CI:1.04,1.30), adjusting for age, family history of diabetes, ethnicity, lifestyle and body mass index (BMI). Relative risks (RR) for developing T2D differed for divorced/separated (1.09 [95%CI: 0.94,1.27]), widowed (1.29 [95%CI:1.06,1.57]), and never married (1.17 [95%CI:0.91,1.52]) after adjusting for age, family history of diabetes and ethnicity. Adjusting for lifestyle and BMI, the RR for T2D associated with widowhood was no longer significant (RR:1.16 [95%CI:0.95,1.41]). When allowing for a 2-year lag period between marital status and disease, RRs of T2D for widowers were augmented and borderline significant (RR:1.24 [95%CI:1.00,1.54]) after full adjustment. In conclusion, not being married, and more specifically, widowhood was more consistently associated with an increased risk of type 2 diabetes in men and this may be mediated, in part, through unfavorable changes in lifestyle, diet and adiposity
