Abstract Objectives The association between olive oil intake and the risk of mortality has not been evaluated before in the US population. Our objective was to examine whether olive oil intake is associated with total and cause-specific mortality in two prospective cohorts of US men and women. We hypothesize that higher olive oil consumption is associated with lower risk of total and cause-specific mortality. Methods We followed 61,096 women (Nurses’ Health Study, 1990–2016) and 31,936 men (Health Professionals Follow-up Study, 1990–2016) who were free of diabetes, cardiovascular disease and cancer at baseline. Diet was assessed by a semi quantitative food frequency questionnaire at baseline and then every 4 years. Cox proportional hazards regressions were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results During 26 years of follow-up, 32,868 deaths occurred. Compared with those participants who never consumed olive oil, those with higher olive oil intake (>1/2 tablespoon/d or >8g/d) had 15% lower risk of total mortality [pooled hazard ratio (95% confidence interval): 0.85 (0.81, 0.88)] after adjustment for potential confounders. Higher olive oil intake was associated with 15% lower risk of CVD death [0.85 (0.78, 0.92)], 38% lower risk of neurodegenerative disease death [0.62 (0.54, 0.71)], and 12% lower risk of respiratory death [0.88 (0.77, 1.00)]. Replacing 10 g of margarine, mayonnaise, and dairy fat with the equivalent amount of olive oil was associated with 7–20% lower risk of total mortality, and death from CVD, cancer, neurodegenerative, and respiratory diseases. No significant associations were observed when olive oil was replacing other vegetable oils combined (corn, safflower, soybean and canola oil). Conclusions We observed that higher olive oil intake was associated with a lower risk of total mortality and cause-specific mortality in a large prospective cohort of U.S. men and women. The substitution of margarine, mayonnaise, and dairy fat with olive oil was associated with a reduced risk of mortality.

Background: Plant-based diets have been associated with lower risk of type 2 diabetes mellitus and cardiovascular disease (CVD) and are recommended for both health and environmental benefits. However, the association between changes in plant-based diet quality and mortality remains unclear. Methods: We investigated the associations between 12-year changes (from 1986 to 1998) in plant-based diet quality assessed by 3 plant-based diet indices (score range, 18–90)—an overall plant-based diet index (PDI), a healthful PDI, and an unhealthful PDI—and subsequent total and cause-specific mortality (1998–2014). Participants were 49 407 women in the Nurses’ Health Study (NHS) and 25 907 men in the Health Professionals Follow-Up Study (HPFS) who were free from CVD and cancer in 1998. Multivariable-adjusted Cox proportional-hazards models were used to estimate hazard ratios (HRs) and 95% CIs. Results: We documented 10 686 deaths including 2046 CVD deaths and 3091 cancer deaths in the NHS over 725 316 person-years of follow-up and 6490 deaths including 1872 CVD deaths and 1772 cancer deaths in the HPFS over 371 322 person-years of follow-up. Compared with participants whose indices remained stable, among those with the greatest increases in diet scores (highest quintile), the pooled multivariable-adjusted HRs for total mortality were 0.95 (95% CI, 0.90–1.00) for PDI, 0.90 (95% CI, 0.85–0.95) for healthful PDI, and 1.12 (95% CI, 1.07–1.18) for unhealthful PDI. Among participants with the greatest decrease (lowest quintile), the multivariable-adjusted HRs were 1.09 (95% CI, 1.04–1.15) for PDI, 1.10 (95% CI, 1.05–1.15) for healthful PDI, and 0.93 (95% CI, 0.88–0.98) for unhealthful PDI. For CVD mortality, the risk associated with a 10-point increase in each PDI was 7% lower (95% CI, 1–12%) for PDI, 9% lower (95% CI, 4–14%) for healthful PDI, and 8% higher (95% CI, 2–14%) for unhealthful PDI. There were no consistent associations between changes in plant-based diet indices and cancer mortality. Conclusions: Improving plant-based diet quality over a 12-year period was associated with a lower risk of total and CVD mortality, whereas increased consumption of an unhealthful plant-based diet was associated with a higher risk of total and CVD mortality.

Background: The previously validated Healthy Heart Score, based on modifiable health behaviors (diet, physical activity, alcohol intake, smoking, and body weight), effectively predicted the 20-year risk of CVD in mid-adulthood. While these lifestyle behaviors are independently associated with many chronic diseases, it remains unknown whether the Healthy Heart Score may extend to an association with overall mortality risk. Thus, we examined the Healthy Heart Score and total and cause-specific mortality in the Nurses’ Health Study (NHS) and Health Professional Follow-up Study (HPFS). Methods: We conducted a prospective analysis among 58,319 women in the NHS (1984-2010) aged 30-55 y and 30,713 in men in the HPFS (1986-2010) aged 40-75 y free of cancer and CVD at baseline. The Healthy Heart Score was calculated at baseline and included 9 factors that best estimated CVD risk: current smoking, higher BMI, low physical activity, lack of moderate alcohol consumption, low intakes of fruits and vegetables, cereal fiber, and nuts, and high intakes of sugar-sweetened beverages and red and processed meats). Cox proportional hazards models estimated hazard ratios (HR) and 95% confidence intervals (CI) and adjusted for various demographics, medical history, medication use and total energy. Results: During 2,075,504 years of follow-up, there were 19,181 total deaths, including 11,464 in women and 7,717 in men. Compared to participants with the lowest predicted 20-year CVD risk based on the Healthy Heart Score (1 st quintile, median CVD risk: 0.01%), participants with the highest predictive CVD risk (5 th quintile, median CVD risk: 0.03%) had a pooled HR (95%CI) of 2.26 (1.86, 2.13) for total mortality; 2.89 (95 CI%, 1.93, 4.32) for CVD mortality; and 2.55 (95% CI 2.39, 2.72) for cancer mortality. Participants in the 5 th quintile vs . the 1 st quintile of the Healthy Heart Score had also a significantly greater risk of death due to CHD (3.40 [2.20, 5.26]), stroke (1.77 [1.00, 3.14]), lung cancer (6.02 [2.83, 12.79]), breast cancer (1.45 [1.13, 1.85]), colon cancer (1.51 (1.17, 1.94)), respiratory disease (3.94 (1.03, 15.14)), and diabetes (3.63 (2.00, 6.59)). Conclusion: The Healthy Heart Score, comprised of 9 self-reported, modifiable lifestyle predictors of CVD, is strongly associated with a greater risk of all-cause and cause-specific mortality. This risk score is a potentially useful tool for risk assessment and counseling of healthy lifestyles to promote longevity

ABSTRACT Background Previous studies have examined dairy products with various fat contents in relation to type 2 diabetes (T2D) risk, although data regarding dairy fat intake per se are sparse. Objectives We aimed to evaluate the association between dairy fat intake and risk of T2D in 3 prospective cohorts. We also examined associations for isocalorically replacing dairy fat with other macronutrients. Methods We prospectively followed 41,808 men in the Health Professionals Follow-Up Study (HPFS; 1986–2012), 65,929 women in the Nurses’ Health Study (NHS; 1984–2012), and 89,565 women in the NHS II (1991–2013). Diet was assessed quadrennially using validated FFQs. Fat intake from dairy products and other relevant sources was expressed as percentage of total energy. Self-reported incident T2D cases were confirmed using validated supplementary questionnaires. Time-dependent Cox proportional hazards regression was used to estimate the HR for dairy fat intake and T2D risk. Results During 4,219,457 person-years of follow-up, we documented 16,511 incident T2D cases. Dairy fat was not associated with risk of T2D when compared with calories from carbohydrates (HR for extreme quintiles: 0.98; 95% CI: 0.95, 1.02). Replacing 5% of calories from dairy fat with other sources of animal fat or carbohydrate from refined grains was associated with a 17% (HR: 1.17; 95% CI: 1.13, 1.21) and a 4% (HR: 1.04; 95% CI: 1.00, 1.08) higher risk of T2D, respectively. Conversely, a 5% calorie replacement with carbohydrate from whole grains was associated with a 7% lower risk of T2D (HR: 0.93; 95% CI: 0.88, 0.98). Conclusions Dairy fat intake was not associated with T2D risk in these cohort studies of US men and women when compared with calories from carbohydrate. Replacing dairy fat with carbohydrates from whole grains was associated with lower risk of T2D. Replacement with other animal fats or refined carbohydrates was associated with higher risk.

Abstract Background Whether mushroom consumption, which is rich in several bioactive compounds, including the crucial antioxidants ergothioneine and glutathione, is inversely associated with low all-cause and cause-specific mortality remains uncertain. This study aimed to prospectively investigate the association between mushroom consumption and all-cause and cause-specific mortality risk. Methods Longitudinal analyses of participants from the Third National Health and Nutrition Examination Survey (NHANES III) extant data (1988–1994). Mushroom intake was assessed by a single 24-h dietary recall using the US Department of Agriculture food codes for recipe foods. All-cause and cause-specific mortality were assessed in all participants linked to the National Death Index mortality data (1988–2015). We used Cox proportional hazards regression models to calculate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for all-cause and cause-specific mortality. Results Among 15,546 participants included in the current analysis, the mean (SE) age was  44.3 (0.5) years. During a mean (SD) follow-up duration of 19.5 (7.4) years , a total of 5826 deaths were documented. Participants who reported consuming mushrooms had lower risk of all-cause mortality compared with those without mushroom intake (adjusted hazard ratio (HR) = 0.84; 95% CI: 0.73–0.98) after adjusting for demographic, major lifestyle factors, overall diet quality, and other dietary factors including total energy. When cause-specific mortality was examined, we did not observe any statistically significant associations with mushroom consumption. Consuming 1-serving of mushrooms per day instead of 1-serving of processed or red meats was associated with lower risk of all-cause mortality (adjusted HR = 0.65; 95% CI: 0.50–0.84). We also observed a dose-response relationship between higher mushroom consumption and lower risk of all-cause mortality (P-trend = 0.03). Conclusion Mushroom consumption was associated with a lower risk of total mortality in this nationally representative sample of US adults.

Background: Given the increased prevalence of cancer survivors in the United States, it is imperative to define risk factors for potential reductions in total and cause-specific mortality. Physical activity (PA) represents a promising target for intervention. Design: We prospectively evaluated PA from questionnaires before and after cancer diagnosis with total and cause-specific mortality among 13,297 subjects diagnosed with invasive cancer combined from the Physicians’ Health Study (PHS) (n=6328), Physicians’ Health Study II (PHS II) (n=912), and Women's Health Study (WHS) (n=6057). WHS and PHS participants were free of baseline cancer; PHS II participants reported no active cancer at baseline. We ascertained PA before and after an incident cancer diagnosis based on reports on repeated follow-up questionnaires. Death was ascertained by medical records and death certificates. Cox regression estimated combined hazard ratios (HRs) of mortality by PA adjusted for age, randomized treatments, BMI, and other lifestyle/demographic factors. We evaluated the interaction between PA before and after cancer diagnosis by comparing PA ≤1 versus ≥2 times/wk. Results: The mean follow-up after cancer diagnosis was 8.0, 7.5, and 5.2 y for WHS, PHS, and PHS II, respectively, during which there were 5623 deaths (WHS, 2164; PHS, 3269; PHS II; 190). Higher PA before cancer diagnosis was associated with significantly lower mortality. Compared with PA ≤ once/wk, the HRs (95% CIs) associated with PA 2-4 and >4 times/wk were 0.87 (0.82-0.93) and 0.88 (0.82-0.94) for total mortality; 0.77 (0.63-0.95) and 0.79 (0.62-0.997) for CVD mortality, and 0.90 (0.83-0.98) and 0.90 (0.83-0.98) for cancer mortality. Higher PA after cancer diagnosis was associated with significantly lower total and cancer mortality and non-significantly lower CVD mortality, with HRs (95% CIs) of 0.65 (0.58-0.72) and 0.66 (0.59-0.73) for total mortality; 0.78 (0.59-1.03) and 0.82 (0.61-1.10) for CVD mortality, and 0.66 (0.57-0.77) and 0.64 (0.55-0.74) for cancer mortality. There was a significant interaction of PA before and after cancer diagnosis for total (p int =0.02) and cancer (p int =0.007) mortality, but not CVD mortality (p int =0.38). Conclusions: Greater PA both before and after cancer diagnosis were significantly associated with lower total and cancer mortality. Higher PA before cancer diagnosis was also associated with lower CVD mortality. PA may be an important target for lower mortality after cancer diagnosis.

ABSTRACT Background Controversy has emerged about the benefits compared with harms of dairy fat, including concerns over long-term effects. Previous observational studies have assessed self-reported estimates of consumption or a single biomarker measure at baseline, which may lead to suboptimal estimation of true risk. Objective The aim of this study was to investigate prospective associations of serial measures of plasma phospholipid fatty acids pentadecanoic (15:0), heptadecanoic (17:0), and trans-palmitoleic (trans-16:1n–7) acids with total mortality, cause-specific mortality, and cardiovascular disease (CVD) risk among older adults. Design Among 2907 US adults aged ≥65 y and free of CVD at baseline, circulating fatty acid concentrations were measured serially at baseline, 6 y, and 13 y. Deaths and CVD events were assessed and adjudicated centrally. Prospective associations were assessed by multivariate-adjusted Cox models incorporating time-dependent exposures and covariates. Results During 22 y of follow-up, 2428 deaths occurred, including 833 from CVD, 1595 from non-CVD causes, and 1301 incident CVD events. In multivariable models, circulating pentadecanoic, heptadecanoic, and trans-palmitoleic acids were not significantly associated with total mortality, with extreme-quintile HRs of 1.05 for pentadecanoic (95% CI: 0.91, 1.22), 1.07 for heptadecanoic (95% CI: 0.93, 1.23), and 1.05 for trans-palmitoleic (95% CI: 0.91, 1.20) acids. Circulating heptadecanoic acid was associated with lower CVD mortality (extreme-quintile HR: 0.77; 95% CI: 0.61, 0.98), especially stroke mortality, with a 42% lower risk when comparing extreme quintiles of heptadecanoic acid concentrations (HR: 0.58; 95% CI: 0.35, 0.97). In contrast, heptadecanoic acid was associated with a higher risk of non-CVD mortality (HR: 1.27; 95% CI: 1.07, 1.52), which was not clearly related to any single subtype of non-CVD death. No significant associations of pentadecanoic, heptadecanoic, or trans-palmitoleic acids were seen for total incident CVD, coronary heart disease, or stroke. Conclusions Long-term exposure to circulating phospholipid pentadecanoic, heptadecanoic, or trans-palmitoleic acids was not significantly associated with total mortality or incident CVD among older adults. High circulating heptadecanoic acid was inversely associated with CVD and stroke mortality and potentially associated with higher risk of non-CVD death.

Background: Sugar sweetened beverages (SSBs) are the single largest source of calories and added sugars in the US diet and regular consumption has been associated with weight gain and risk of chronic diseases. Artificially sweetened beverages (ASBs) are often suggested as alternatives to SSB but little is known about their long-term health effects. Whether consumption of SSBs or ASBs is associated with risk of mortality is unknown. Methods: We prospectively followed 38,602 men from the Health Professional’s Follow-up study (1986-2010) and 82,592 women from the Nurses’ Health study (1980-2010) who were free from cardiovascular disease (CVD) and cancer at baseline. Diet was assessed using validated food frequency questionnaires every 4 years and Cox Proportional Hazards regression was used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI). Results: We documented 27,691 deaths (6,631 CVD and 10,447 cancer deaths) during 3.14 million person-years. After adjusting for major dietary and lifestyle risk factors, and BMI, baseline diabetes, hypertension and hypercholesterolemia, consumption of SSBs was associated with an increased risk of total mortality, which was mainly driven by CVD mortality among individuals consuming at least 2 servings per day; pooled HRs (95% CIs) across categories (<1/month, 1-4/month, 2-6/week, 1-<2/day and ≥2/day) were 1.00, 0.95 (0.91, 0.98), 0.96 (0.93, 0.99), 1.02 (0.96, 1.08), and 1.18 (1.04, 1.33), respectively (P-trend= 0.0001) for total mortality, and 1.00, 0.97 (0.90, 1.02), 0.96 (0.90, 1.02), 1.04 (0.93, 1.16) and 1.28 (1.09, 1.51), respectively (P-trend=0.007) for CVD mortality. In contrast, ASBs were not associated with mortality; pooled HR’s (95% CIs) across categories (<1/month, 1-4/month, 2-6/week, 1-<2/day and ≥2/day) were 1.00, 0.92 (0.89, 0.95), 0.91 (0.86, 0.97), 0.91 (0.86, 0.95) and 0.99 (0.85, 1.15), respectively (P-trend=0.50) for total mortality and 1.00, 0.86 (0.80, 0.92), 0.87 (0.81, 0.94), 0.96 (0.88, 1.06) and 0.96 (0.74, 1.25), respectively (P-trend=0.99) for CVD mortality. No associations were observed with cancer mortality for either SSBs or ASBs in multi-variable adjusted models. Conclusion: Regular consumption of SSBs is associated with an increased risk of total and CVD mortality, providing additional support for recommendations and policies to limit intake of these beverages.

BACKGROUND: Few studies have examined prospectively the relationship between baseline high-density lipoprotein (HDL) cholesterol and longevity. OBJECTIVES: We sought to examine whether higher HDL levels were associated with lower risk of all-cause, cardiovascular (CVD), and non-CVD mortality prior to age 90 in the Physicians’ Health Study (PHS). METHODS: We considered a baseline cohort of 1351 PHS participants who provided bloods between 1997 and 2001 and were old enough to reach age 90 by March 4, 2009. Included subjects had complete baseline data on HDL and total cholesterol; lifestyle factors including smoking, exercise, alcohol consumption, and BMI; and comorbidities including hypertension, diabetes mellitus, congestive heart failure, cancer, and stroke. We used Cox proportional hazards to determine the HRs and 95% CIs for all-cause, CVD, and non-CVD mortality prior to age 90, adjusting for baseline age, co-morbidities, and non-HDL cholesterol. RESULTS: At baseline, the cohort had a mean (SD) age of 81.9 (2.9) years and a mean (SD) HDL cholesterol of 44.8(16.5) mg/dL. After a mean follow-up of 6.8 years (maximum 12.3 years), 501 (37.1%) of men died prior to age 90. In multi-variable adjusted analyses, men in the highest HDL-C quartile (≥54.1 mg/dL) had a 28% lower risk (HR 0.72, 95% CI 0.55-0.95) of all-cause mortality prior to age 90 compared to men in the lowest HDL-C quartile (<32.8 mg/dL). From the lowest to highest HDL quartile, age-adjusted HR(95%CI) for CVD mortality prior to age 90 were 0.66 (0.44-0.99), 0.58 (0.38-0.90), and 0.53 (0.34-0.82) (p for trend 0.004). There was no significant association between baseline HDL cholesterol and non-CVD death. CONCLUSION: In a cohort of older male physicians with long-term follow-up, baseline HDL cholesterol was inversely associated with the risk of dying prior to age 90, largely explained by an inverse association between HDL and CVD mortality.

AbstractObjectiveTo examine the association of consumption of dairy foods with risk of total and cause specific mortality in women and men.DesignThree prospective cohort studies with repeated measures of diet and lifestyle factors.SettingNurses’ Health Study, Nurses’ Health Study II, and the Health Professionals Follow-up Study, in the United States.Participants168 153 women and 49 602 men without cardiovascular disease or cancer at baseline.Main outcome measureDeath confirmed by state vital records, the national death index, or reported by families and the postal system. During up to 32 years of follow-up, 51 438 deaths were documented, including 12 143 cardiovascular deaths and 15 120 cancer deaths. Multivariable analysis further adjusted for family history of cardiovascular disease and cancer, physical activity, overall dietary pattern (alternate healthy eating index 2010), total energy intake, smoking status, alcohol consumption, menopausal status (women only), and postmenopausal hormone use (women only).ResultsCompared to the lowest category of total dairy consumption (average 0.8 servings/day), the multivariate pooled hazard ratio for total mortality was 0.98 (95% confidence interval 0.96 to 1.01) for the second category of dairy consumption (average 1.5 servings/day), 1.00 (0.97 to 1.03) for the third (average 2.0 servings/day), 1.02 (0.99 to 1.05) for the fourth (average 2.8 servings/day), and 1.07 (1.04 to 1.10) for highest category (average 4.2 servings/day; P for trend <0.001). For the highest compared to the lowest category of total dairy consumption, the hazard ratio was 1.02 (0.95 to 1.08) for cardiovascular mortality and 1.05 (0.99 to 1.11) for cancer mortality. For subtypes of dairy products, whole milk intake was significantly associated with higher risks of total mortality (hazard ratio per 0.5 additional serving/day 1.11, 1.09 to 1.14), cardiovascular mortality (1.09, 1.03 to 1.15), and cancer mortality (1.11, 1.06 to 1.17). In food substitution analyses, consumption of nuts, legumes, or whole grains instead of dairy foods was associated with a lower mortality, whereas consumption of red and processed meat instead of dairy foods was associated with higher mortality.ConclusionThese data from large cohorts do not support an inverse association between high amount of total dairy consumption and risk of mortality. The health effects of dairy could depend on the comparison foods used to replace dairy. Slightly higher cancer mortality was non-significantly associated with dairy consumption, but warrants further investigation.

ObjectiveWe prospectively examined whether women with physician-diagnosed restless legs syndrome (RLS) had a higher risk of total and cardiovascular disease (CVD) mortality relative to those without RLS.MethodsThe current study included 57,417 women (mean age 67 years) from the Nurses' Health Study without cancer, renal failure, and CVD at baseline (2002). Main outcomes were total and CVD mortality. We used the Cox proportional hazards model to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause and CVD-specific mortality based on RLS status, adjusting for age, presence of major chronic diseases, and other potential confounders.ResultsWe documented 6,448 deaths during 10 years of follow-up. We did not observe a significant association between presence of physician-diagnosed RLS and high risk of total mortality (adjusted HR 1.15, 95% CI 0.98–1.34). When cause-specific mortality was studied, participants with RLS had a significantly higher risk of CVD mortality (adjusted HR 1.43, 95% CI 1.02–2.00) relative to those without RLS after adjustment for potential confounders. Longer duration of RLS diagnosis was significantly associated with a higher risk of CVD mortality (p for trend = 0.04). Excluding participants with common RLS comorbidities strengthened the association between RLS and total (adjusted HR 1.43, 95% CI 1.03–1.97) and CVD mortality (adjusted HR 2.27, 95% CI 1.21–4.28). However, we did not find a significant association between RLS and mortality due to cancer and other causes.ConclusionsWomen with RLS had a higher CVD mortality rate, which may not be fully explained by common co-occurring disorders of RLS.
