Aim: To investigate the association of sarcopenia with cardiovascular disease (CVD) incidence in people with type 2 diabetes., Materials and Methods: A prospective cohort study with 11 974 White European UK Biobank participants with type 2 diabetes, aged 40-70 years, included. Sarcopenia was defined based on the European Working Group on Sarcopenia in Older People as either non-sarcopenic or sarcopenic. Outcomes included CVD, stroke, heart failure (HF) and myocardial infarction (MI). The association between sarcopenia and the incidence of outcomes was investigated using Cox proportional hazard models adjusted for sociodemographic and lifestyle factors. The rate advancement period was used to estimate the time period by which CVD is advanced because of sarcopenia., Results: Over a median follow-up of 10.7 years, 1957 participants developed CVDs: 373 had a stroke, 307 had an MI and 742 developed HF. Compared with non-sarcopenia, those with sarcopenia had higher risks of CVD (HR 1.89 [95% CI 1.61; 2.21]), HF (HR 2.59 [95% CI 2.12; 3.18]), stroke (HR 1.90 [95% CI 1.38; 2.63]), and MI (HR 1.56 [95% CI 1.04; 2.33]) after adjustment for all covariates. Those with sarcopenia had CVD incidence rates equivalent to those without sarcopenia who were 14.5 years older. Similar results were found for stroke, HF and MI., Conclusions: In people with type 2 diabetes, sarcopenia increased the risk of developing CVD, which might occur earlier than in those without sarcopenia. Therefore, sarcopenia screening and prevention in patients with type 2 diabetes may be useful to prevent the complications of CVD., (© 2023 The Authors.

Introduction: Physical inactivity is associated with a higher risk of chronic diseases. Regular stair use can contribute to increasing physical activity in the population. This study aimed to investigate the association between flights of stairs used daily at home and all-cause mortality and cause-specific incidence and mortality., Methods: Of the 502,628 UK Biobank participants recruited between 2007 and 2010, 442,027 (mean age, 56±8 years) had available data and were included in the analyses conducted in 2023. Participants were categorized on the basis of flights of stairs climbed daily (1-5, 6-10, 11-15, >15). The disease-specific outcomes were cardiovascular disease, respiratory disease, cancer, type 2 diabetes, and all-cause dementia. Cox proportional hazard models, adjusted for sociodemographic, lifestyle, and health-related confounding factors, were used to analyze the associations between stair use frequency and health outcomes., Results: Participants were followed up for a median of 10.9 years. Climbing stairs >15 times per day was associated with a lower risk of 8 of the 9 outcomes analyzed than not using stairs. The magnitude of association ranged from 3% (95% CI=0.94, 0.99) lower risk for all-cause cancer to 51% (95% CI=0.39, 0.60) lower risk of chronic obstructive pulmonary disease. Findings were similar for mortality outcomes, with the hazard ratios ranging from 0.82 (95% CI=0.77, 0.87) for all-cause cancer to 0.46 (95% CI=0.23, 0.92) for chronic obstructive pulmonary disease mortality., Conclusions: Stair use was associated with a lower risk of all-cause mortality and cause-specific incidence and mortality independent of confounding factors, including adiposity and multimorbidity., (Copyright © 2023 American Journal of Preventive Medicine.

To investigate the dose-response associations of dietary inflammatory potential with all-cause mortality and incident cardiovascular disease (CVD) and cancer., Methods: This was a prospective cohort study of 198,265 UK Biobank participants who completed at least 1 dietary assessment. A web based 24 hours recall questionnaire was used to derive the energy-adjusted dietary inflammatory index (E-DII). All-cause mortality and incident CVD and cancer ascertained from linked records., Results: After adjusting for socio-demographic and lifestyle factors, there were J-shaped associations of E-DII with all-cause mortality and CVD, and a relatively linear association with cancer. When E-DII was <0, E-DII was not associated with any of the outcomes. When E-DII was ≥0, the linear associations were strongest in all-cause mortality (HR 1.09, 95% CI, 1.05-1.13), followed by CVD (HR 1.06, 95% CI, 1.03-1.09), and cancer (HR 1.03, 95%,CI, 1.01-1.05)., Conclusion: Dietary inflammatory potential was associated with mortality and CVD primarily when the diet is proinflammatory., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Background: Being breastfed is associated with lower cardiovascular risk factors but, to date, no studies have demonstrated a protective effect on cardiovascular disease (CVD). This study aims to address the limitations of previous studies, specifically insufficient statistical power and residual confounding, to determine if such association exists., Methods: This is a population-based retrospective cohort study of 320 249 men and women aged 40-69 years. Breastfeeding status was self-reported. CVD and myocardial infarction (MI) events and deaths based via linkage to hospitalization and death records., Results: Overall, 28 469 (8.4%) participants experienced a CVD event and 5174 (1.6%) experienced an MI. Following adjustment for sociodemographic, lifestyle and early life confounders, breastfeeding was associated with a reduced risk of CVD events (HR 0.97, 95% CI 0.94-1.00, P = 0.041), CVD deaths (HR 0.91, 95% CI 0.84-0.98, P = 0.017), MI events (HR 0.93, 95% CI 0.87-0.99, P = 0.033) and MI deaths (HR 0.81, 95% CI 0.67-0.98, P = 0.026)., Conclusions: Child health benefits of breastfeeding are well established. However, the benefits of breastfeeding may extend into later life reinforcing the need to encourage and support breastfeeding., (© The Author(s) 2023.

Obesity is causally associated with multiple cardiovascular outcomes but effective population measure to control obesity is limited. This study aims to decipher to which extent excess atherosclerotic cardiovascular diseases (ASCVD) and heart failure (HF) risk due to obesity can be explained by conventional risk factors. This is a prospective cohort study of 404,332 White UK Biobank participants. Participants with prior CVDs or other chronic diseases at baseline, or body mass index <18.5 kg/m 2 were excluded. Data were collected at the baseline assessment between 2006 and 2010. Linkage to death registrations and hospital admission records was used to ascertain ASCVD and HF outcomes up to late 2021. Obesity was defined as body mass index ≥30 kg/m 2 . Candidate mediators included lipids, blood pressure (BP), glycated hemoglobin (HbA1c), and liver and kidney function markers, which were chosen based on clinical trials and Mendelian randomization studies. Cox proportional hazard models were used to estimate hazard ratios (HR) and their 95% confidence intervals (CIs). Mediation analysis based on g-formula was used to separately estimate the relative importance of mediators for ASCVD and HF. Compared with people without obesity, obese people had an increased risk of ASCVD (HR 1.30, 95% CI, 1.26-1.35) and HF (HR 2.04, 95% CI, 1.96-2.13) after adjusting for sociodemographic and lifestyle factors and medications for cholesterol, BP and insulin. The strongest mediators for ASCVD were renal function (eGFR: mediation proportion: 44.6%), BP (SBP: 24.4%; DBP: 31.1%), triglycerides (19.6%), and hyperglycemia (HbA1c 18.9%). These mediators collectively explained more excess risk of ASCVD than that of HF. Interventions that help obese individuals to maintain healthy lipid concentrations, BP, glycemic control, and kidney function could potentially alleviate a sizable proportion of the ASCVD burden. However, HF burden could not be meaningfully reduced without weight management., (Copyright © 2023 The Author(s). Published by Elsevier Inc. All rights reserved.)

Background: Growing evidence suggests that individuals with anxiety disorder have an elevated risk of cardiovascular disease (CVD) but few studies have assessed this association independently of or jointly with depression., Methods: We conducted a prospective cohort study using UK Biobank. Diagnoses of anxiety disorder, depression, and CVDs were ascertained through linked hospital admission and mortality data. Individual and joint associations between anxiety disorder and depression and CVD overall, as well as each of myocardial infarction, stroke/transient ischemic attack, and heart failure, were analyzed using Cox proportional hazard models and interaction tests., Results: Among the 431,973 participants, the risk of CVD was higher among those who had been diagnosed with anxiety disorder only (hazard ratio [HR] 1.72; 95% confidence interval [CI] 1.32-2.24), depression only (HR 2.07; 95% CI 1.79-2.40), and both conditions (HR 2.89; 95% CI 2.03-4.11) compared to those without these conditions, respectively. There was very little evidence of multiplicative or additive interaction. Results were similar for myocardial infarction, stroke/transient ischemic attack, and heart failure., Conclusions: Having anxiety is associated with the same magnitude of increased risk of CVD among people who do not have depression and those who do. Anxiety disorder should be considered for inclusion in CVD risk prediction and stratification, in addition to depression.

To investigate the association between the Life's Essential 8 (LE8) score and the incidence of four cardiovascular outcomes (ischemic heart disease, myocardial infarction, stroke, and heart failure [HF]) - separately and as a composite outcome of major adverse cardiovascular events (MACE) - in UK Biobank. 250,825 participants were included in this prospective study. Smoking, non-HDL cholesterol, blood pressure, body mass index, HbA1c, physical activity, diet, and sleep were used to create a modified version of the LE8 score. Associations between the score (both as a continuous score and as quartiles) and outcomes were investigated using adjusted Cox proportional hazard models. The potential impact fractions of two scenarios were also calculated. Over a median follow-up of 10.4 years, there were 25,068 MACE. Compared to individuals in the highest quartile of the score (healthiest), those in the lowest quartile (least healthy) had 2.07 (95% CI: 1.99; 2.16) higher risk for MACE. The highest relative risk gradient of the individual outcomes was observed for HF (HR lowest quartile : 2.67 [95% CI: 2.42; 2.94]). The magnitude of association was stronger in participants below 50 years, women, and ethnic minorities. A targeted intervention that increased, by 10-points, the score among individuals in the lowest quartile could have prevented 9.2% of MACE. Individuals with a lower LE8 score experienced more MACE, driven especially by incident HF. Our scenarios suggested that relevant interventions targeted towards those in the lowest quartile may have a greater impact than interventions producing small equal changes across all quartiles., Competing Interests: Declaration of Competing Interest N.S declares consulting fees and/or speaker honoraria from Abbott Laboratories, Afimmune, Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Hanmi Pharmaceuticals, Janssen, Merck Sharp & Dohme, Novartis, Novo Nordisk, Pfizer, and Sanofi; and grant support paid to his university from AstraZeneca, Boehringer Ingelheim, Novartis, and Roche Diagnostics.

Background: Vegetarian diets are heterogeneous and their health benefits may vary. This study aimed to compare the cardiovascular risk among vegetarian diets that meet existing health guidelines, those that do not, and diets that include red meat., Methods: 391,124 participants (55.5% women) from the UK Biobank prospective population-based study were included. Using data from a food frequency questionnaire, participants were categorised into lacto-vegetarian or meat-eaters. Then, both groups were dichotomised into a healthier and less healthy group using an unweighted score based on current UK guidelines. Ischaemic heart disease (IHD) and myocardial infarction (MI) incidence - both separately and as a composite of major adverse cardiovascular events (MACE) - were the outcomes included. Associations between types of diets and health outcomes were investigated using Cox proportional hazard models adjusted for confounder factors., Results: After a median follow-up of 10.4 years, there were 40,048 MACE. When the analyses were adjusted for prevalent morbidity and lifestyle factors, people who followed healthier vegetarian and meat-eater diets had 18% (95% CI: 0.73 to 0.92) and 5% (95% CI: 0.93 to 0.97) lower risk of MACE than less healthy meat-eaters. Similar patterns were identified for the individual outcomes, with the strongest association observed for MI. The cardiovaculasr risk among less healthy vegetarians and less healthy meat-eaters were not significnatly different., Conclusions: Vegetarian diets are heterogeneous and the cardiovascular risk varied accordingly. Future studies should consider the overall dietary patterns of vegetarians rather than just based on meat consumption. Guidelines advocating a plant-based diet need to stress the importance of overall diet quality in addition to the reduction of meat., Competing Interests: Conflict of Interest None to declare., (Copyright © 2023 The Authors.

Background: This study aimed to investigate the associations of grip strength with incidence and mortality from dementia and whether these associations differ by sociodemographic and lifestyle factors., Methods: A total of 466 788 participants of the UK Biobank (median age 56.5 years, 54.5% women). The outcome was all-cause dementia incidence and mortality and the exposure was grip strength. Grip strength was assessed using a Jamar J00105 hydraulic hand dynamometer., Results: Excluding the first 2 years of follow-up (landmark analysis), mean follow-up was 9.1 years (inter-quartile range: 8.3; 9.7) for incidence and 9.3 (inter-quartile range: 8.7; 10.0) for mortality. During this time, 4087 participants developed dementia, and 1309 died from it. Lower grip strength was associated with a higher risk of dementia incidence and mortality independent of major confounding factors (P < 0.001). Individuals in the lowest quintile of grip strength had 72% [95% confidence interval (CI): 1.55; 1.92] higher incident dementia risk and 87% [95% CI: 1.55; 2.26] higher risk of dementia mortality compared with those in the highest quintile. Our PAF analyses indicate that 30.1% of dementia cases and 32.3% of dementia deaths are attributable to having low grip strength. The association between grip strength and dementia outcomes did not differ by lifestyle or sociodemographic factors., Conclusions: Lower grip strength was associated with a higher risk of all-cause dementia incidence and mortality, independently of important confounding factors., (© 2022 The Authors.

Background: This study aimed to study the association between shift work and incident and fatal cardiovascular disease (CVD), and to explore modifying and mediating factors., Methods: This is a population-based, prospective cohort study with a median follow-up of 11 years; 238 661 UK Biobank participants who were in paid employment or self-employed at baseline assessment were included., Results: Shift workers had higher risk of incident [hazard ratio (HR) 1.11, 95% confidence interval (CI) 1.06-1.19] and fatal (HR 1.25, 95% CI 1.08-1.44) CVD compared with non-shift workers, after adjusting for socio-economic and work-related factors. The risk was higher with longer duration of shift work, in women and in jobs with little heavy manual labour. Current smoking, short sleep duration, poor sleep quality, adiposity, higher glycated haemoglobin and higher cystatin C were identified as the main potentially modifiable mediators. Mediators collectively explained 52.3% of the associations between shift work and incident CVDs., Conclusions: Shift workers have higher risk of incident and fatal CVD, partly mediated through modifiable risk factors such as smoking, sleep duration and quality, adiposity and metabolic status. Workplace interventions targeting these mediators have the potential to alleviate shift workers' CVD risk., (© The Author(s) 2021.

Background: Ethnic differences in cardiovascular disease (CVD) risk have been known for decades, but a systematic exploration of how exposure and susceptibility to risk factors may contribute is lacking. This study aimed to investigate the potential impact of differential exposure and susceptibility between South Asian, Black, and White individuals., Methods: This is a population-based prospective cohort study of UK Biobank participants with a median follow-up of 11.3 years. The association between ethnic group and CVD risk was studied. Additional risk factors were then adjusted to examine mediations. Moderation analysis was conducted to identify whether risk factors had a stronger association in the ethnic minority groups. Population attributable fractions were also calculated to quantify the relative contributions of risk factors for each ethnic group., Results: When adjusted for only age and sex, there was a higher risk of CVD among South Asian (n=8815; HR [95% CI] 1.69 [1.59-1.79]) and Black (n=7526; HR [95% CI] 1.12 [1.03-1.22]) compared with White participants (n=434,809). The excess risk of Black participants was completely attenuated following adjustment for deprivation. Compared with White participants, the associations of BMI, triglycerides, and HbA1c with CVD were stronger in South Asians. Adiposity was attributable to the highest proportion of CVD regardless of ethnicity. Smoking had the second largest contribution to CVD among White and Black participants, and HbA1c among South Asian participants., Conclusions: Adiposity is an important risk factor for CVD regardless of ethnicity. Ethnic inequalities in CVD incidence may be best tackled by targeting interventions according to ethnic differences in risk profiles., (© 2022. The Author(s).)

Aims: To investigate the population attributable fraction due to elevated lipoprotein (a) (Lp(a)) and the utility of measuring Lp(a) in cardiovascular disease (CVD) risk prediction., Methods and Results: In 413 734 participants from UK Biobank, associations of serum Lp(a) with composite fatal/non-fatal CVD (n = 10 066 events), fatal CVD (n = 3247), coronary heart disease (CHD; n = 18 292), peripheral vascular disease (PVD; n = 2716), and aortic stenosis (n = 901) were compared using Cox models. Median Lp(a) was 19.7 nmol/L (interquartile interval 7.6-75.3 nmol/L). About 20.8% had Lp(a) values >100 nmol/L; 9.2% had values >175 nmol/L. After adjustment for classical risk factors, 1 SD increment in log Lp(a) was associated with a hazard ratio for fatal/non-fatal CVD of 1.12 [95% confidence interval (CI) 1.10-1.15]. Similar associations were observed with fatal CVD, CHD, PVD, and aortic stenosis. Adding Lp(a) to a prediction model containing traditional CVD risk factors in a primary prevention group improved the C-index by +0.0017 (95% CI 0.0008-0.0026). In the whole cohort, Lp(a) above 100 nmol/L was associated with a population attributable fraction (PAF) of 5.8% (95% CI 4.9-6.7%), and for Lp(a) above 175 nmol/L the PAF was 3.0% (2.4-3.6%). Assuming causality and an achieved Lp(a) reduction of 80%, an ongoing trial to lower Lp(a) in patients with CVD and Lp(a) above 175 nmol/L may reduce CVD risk by 20.0% and CHD by 24.4%. Similar benefits were also modelled in the whole cohort, regardless of baseline CVD., Conclusion: Population screening for elevated Lp(a) may help to predict CVD and target Lp(a) lowering drugs, if such drugs prove efficacious, to those with markedly elevated levels., (© The Author(s) 2020.

Objective: To investigate sex-specific associations of osteoporosis with incidence of and mortality from cardiovascular disease (CVD), respiratory disease, and cancer as well as with all-cause mortality., Methods: In total, 305,072 participants (53% [161,383] women) of UK Biobank were included in this study (2007-2010). Self-reported diagnosis of osteoporosis at baseline was the exposure of interest. The outcomes were CVD, respiratory disease, chronic obstructive pulmonary disease (COPD), all cancer, and prostate and breast cancer incidence and mortality and all-cause mortality. Associations between osteoporosis and outcomes were investigated using Cox proportional hazards models., Results: In men, osteoporosis was associated with a higher incident risk of all respiratory diseases (hazard ratio [HR], 1.26; 95% CI, 1.06 to 1.50) including COPD (HR, 1.82; 95% CI, 1.38 to 2.40). Men with osteoporosis also had a higher mortality risk from all causes (HR, 1.71; 95% CI, 1.38 to 2.11), CVD (HR, 1.68; 95% CI, 1.19 to 2.37), respiratory disease (HR, 2.35; 95% CI, 1.70 to 3.24), and COPD (HR, 3.64; 95% CI, 2.24 to 5.91). These associations persisted after adjustment for age, body mass index, and comorbidities. Women with osteoporosis had a higher risk of incident CVD (HR, 1.24; 95% CI, 1.97 to 1.44), respiratory disease (HR, 1.23; 95% CI, 1.13 to 1.33), and COPD (HR, 1.29; 95% CI, 1.10 to 1.52). Women with osteoporosis also had a higher mortality risk from respiratory disease (HR, 1.31; 95% CI, 1.00 to 1.72) and breast cancer (HR, 1.60; 95% CI, 1.14 to 2.26)., Conclusion: Compared with women, men with osteoporosis had a higher risk of all-cause mortality, mortality from respiratory diseases including COPD, and cancer incidence. Osteoporosis was strongly associated with respiratory disease and COPD in both sexes, even after full adjustment for covariates, although men with osteoporosis experienced a higher risk of adverse outcomes., (Copyright © 2021 Mayo Foundation for Medical Education and Research.

Objective: To develop a score from cumulative dietary risk factors and examine its nonlinear associations with cardiovascular disease (CVD) and cancer incidence and mortality, as well as all-cause mortality., Patients and Methods: There were 422,702 participants from UK Biobank included in this prospective study. Cumulative dietary risk factors were represented using a score ranging from 0 (healthiest) to 9 (least healthy). This was derived from 9 food items based on current UK guidelines using baseline data. Associations between the cumulative score and health outcomes were investigated using nonlinear penalized cubic splines fitted in Cox proportional hazard models. Follow-up was conducted until June 2020 for mortality, and for incidence, up to June 2020 in England and March 2017 in Wales and Scotland., Results: The median follow-up period was 9.0 years for incidence outcomes and 9.3 years for mortality outcomes. Each 1-point increment in the cumulative dietary risk factors score was associated with higher risk for incidence and mortality of the outcomes studied. The highest risks were identified for mortality due to heart failure (8.0% higher), CVD, and ischemic heart disease (both 7.0% higher). In addition, a higher diet score accounted for 18.8% of all deaths, 4.47% of incident cases of CVD, 25.5% of CVD deaths, 7.7% of incident cancers, and 18.2% of all cancer deaths., Conclusion: Our findings show that dietary risk factors contributed to a large proportion of CVD and cancer events, as well as deaths, among those who did not meet most dietary recommendations., (Copyright © 2021 Mayo Foundation for Medical Education and Research.

Background: Sarcopenia and frailty are strongly associated with disease incidence and mortality. However, there is limited evidence regarding their joint association with health outcomes. This study aimed to investigate the joint association of sarcopenia and frailty with cardiovascular disease (CVD), respiratory disease and cancer incidence and mortality as well as all-cause mortality in middle-aged and older adults in the UK Biobank study., Methods: 316,980 UK Biobank participants were included in this prospective study (53.1% women). Sarcopenia was defined according to the EWGSOP2 2019. Frailty was defined using a modified version of the Fried criteria. Combined classifications of sarcopenia and frailty were generated with the following seven subgroups derived: i) normal, ii) non-sarcopenic/pre-frail, iii) non-sarcopenic/frail, iv) pre-sarcopenic/pre-frail, v) pre-sarcopenic/frail, vi) sarcopenic/pre-frail, and vii) sarcopenic/frail. No participants had (pre)sarcopenia but not frailty. Associations between these exposures and health outcomes (incidence and mortality from cardiovascular and respiratory diseases, cancer, as well as, all-cause mortality) were investigated using Cox-proportional hazard models., Results: 51.7% of the participants were not sarcopenic nor frail (normal), 41.3% were pre-frail or frail, 6.5% pre-sarcopenia and frail (including pre-frail) and 0.5% as having both sarcopenia and frailty (including pre-frailty). The combination sarcopenic/frail showed the strongest association with CVD (HR: 1.68 [95% CI: 1.22 to 2.30]) and respiratory disease incidence (HR: 1.77 [95% CI: 1.40 to 2.24]) and for mortality from all-cause (HR: 2.27 [95% CI: 1.64 to 3.13]), respiratory disease (HR: 3.50 [95% CI: 1.97 to 6.23]), and cancer (HR: 1.92 [95% CI: 1.08 to 3.38]). Finally, when we investigated the associations between the outcomes and exposures by age groups (≥and <60 years), we identified that, for many outcomes and categories, the associations were higher in younger individuals compared with older adults., Conclusion: Our findings indicate that different combinations of sarcopenia and frailty were associated with adverse health outcomes, highlighting the joint association between both conditions. However, those individuals with sarcopenia and frailty showed the strongest associations with CVD and respiratory disease incidence and mortality for all-cause and respiratory disease and cancer., Competing Interests: Conflict of interest The authors declare no conflict of interest., (Copyright © 2020 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Aims: To compare the incidence and mortality risk for cardiovascular diseases (CVD) [CVD and also ischaemic heart disease (IHD), myocardial infarction (MI), stroke, and heart failure (HF)] among people with different types of diets-including vegetarians, fish eaters, fish and poultry eaters, and meat-eaters-using data from UK Biobank., Methods and Results: A total of 422 791 participants (55.4% women) were included in this prospective analysis. Using data from a food frequency questionnaire, four types of diets were derived. Associations between types of diets and health outcomes were investigated using Cox proportional hazard models. Meat-eaters comprised 94.7% of the cohort and were more likely to be obese than other diet groups. After a median follow-up of 8.5 years, fish eaters, compared with meat-eaters, had lower risks of incident CVD {hazard ratios (HR): 0.93 [95% confidence intervals (CI): 0.88-0.97]}, IHD [HR: 0.79 (95% CI: 0.70-0.88)], MI [HR: 0.70 (95% CI: 0.56-0.88)], stroke [HR: 0.79 (95% CI: 0.63-0.98)] and HF [HR: 0.78 (95% CI: 0.63-0.97)], after adjusting for confounders. Vegetarians had lower risk of CVD incidence [HR: 0.91 (95% CI: 0.86-0.96)] relative to meat-eaters. In contrast, the risk of adverse outcomes was not different in fish and poultry eaters compared with meat-eaters. No associations were identified between types of diets and CVD mortality., Conclusion: Eating fish rather than meat or poultry was associated with a lower risk of a range of adverse cardiovascular outcomes. Vegetarianism was only associated with a lower risk of CVD incidence., (Published on behalf of the European Society of Cardiology. All rights reserved. © The Author(s) 2020.

Introduction: It is unclear what combinations of physical capability markers used to define sarcopenia have the strongest associations with health outcomes., Aim: To compare the associations between different combinations of physical capability markers of sarcopenia with cardiovascular and respiratory outcomes and all-cause mortality., Study Design: 469,830 UK Biobank participants were included in this prospective study. Four groups were derived based on combinations of three physical capability markers used to define sarcopenia or severe sarcopenia: gait speed, grip strength and muscle mass. Outcomes studied were all-cause mortality, as well as incidence and mortality from cardiovascular disease (CVD), respiratory disease and chronic obstructive pulmonary disease (COPD)., Results: All combinations of physical capability markers used to define sarcopenia or severe sarcopenia identified individuals at increased risk of respiratory disease and all-cause mortality. However, the definition most strongly associated with a wide range of adverse health outcomes was the combination of slow gait speed plus low muscle mass, followed by severe sarcopenia, and the combination of slow gait speed plus low grip strength. The current definition of sarcopenia (low grip strength plus low muscle mass) had the weakest associations with all-cause (HR: 1.35 [95% CI: 1.07 to 1.71]) and respiratory mortality (HR: 1.88 [95% CI: 1.15 to 3.10]), as well as respiratory disease (HR: 1.38 [95% CI: 1.11 to 1.73]) and COPD incidence (HR: 2.08 [95% CI: 1.14 to 3.79])., Conclusions: Associations of sarcopenia with adverse outcomes were strongest when sarcopenia was defined as slow gait speed plus low muscle mass, followed by severe sarcopenia, suggesting that this combination of physical capability markers should be still considered in the diagnosis of sarcopenia., Competing Interests: Conflict of intereset The authors declare that they have no conflict of interest., (Copyright © 2020 Elsevier B.V.

Background: Child maltreatment is associated with cardiovascular disease (CVD), but mediation pathways have not been fully elucidated. The aim of the current study was to determine and quantify the underlying pathways linking child maltreatment and CVD., Methods: We conducted a retrospective cohort study using the UK Biobank. The number and types of child maltreatment, including abuse and neglect, were recalled by the participants. Lifestyle, biological, physical, and mental health factors measured at baseline were explored as potential mediators. Incident CVD was ascertained through record linkage after baseline measurement. Age, sex, ethnicity, area-based deprivation, and education level were adjusted for as confounders. Cox proportional hazard models were conducted to test for associations between child maltreatment and incident CVD., Results: A total of 152,040 participants who completed the child maltreatment assessment were included in the analyses, and one third reported at least one type of child maltreatment. There was a dose-response relationship between the number of maltreatment types and incident CVD. On average, each additional type of child maltreatment was associated with an 11% (95% CI 8-14%, P < 0.0001) increased risk of CVD. The majority (56.2%) of the association was mediated through depressive symptoms, followed by smoking (14.7%), high-density lipoprotein cholesterol (8.7%), and sleep duration (2.4%)., Conclusion: Child maltreatment is associated with incident CVD through a combination of mental health, lifestyle, and biological pathways. Therefore, in addition to interventions to reduce the occurrence of child maltreatment, attention should be targeted at promoting healthy lifestyles and preventing, identifying, and treating depression among children and adults who have previously been maltreated.

Objective: To investigate whether the addition of grip strength and/or self-reported walking pace to established cardiovascular disease (CVD) risk scores improves their predictive abilities., Patients and Methods: A total of 406,834 participants from the UK Biobank, with baseline measurements between March 13, 2006, and October 1, 2010, without CVD at baseline were included in this study. Associations of grip strength and walking pace with CVD outcomes were investigated using Cox models adjusting for classical risk factors (as included in established risk scores), and predictive utility was determined by changes in C-index and categorical net reclassification index., Results: Over a median of 8.87 years of follow-up (interquartile range 3, 8.25-9.47 years), there were 7274 composite fatal/nonfatal events (on the basis of the American College of Cardiology/American Heart Association [ACC/AHA] outcome) and 1955 fatal events (on the basis of the Systematic Coronary Risk Evaluation [SCORE] risk score). Both grip strength and walking pace were inversely associated with CVD outcomes after adjusting for classical risk factors. Addition of grip strength (change in C-index: ACC/AHA, +0.0017; SCORE, +0.0047), usual walking pace (ACC/AHA, +0.0031; SCORE, +0.0130), and both combined (ACC/AHA, +0.0041; SCORE, +0.0148) improved the C-index and also improved the net reclassification index (grip, +0.55%; walking pace, +0.53%; combined, 1.12%)., Conclusion: The present study has found that the addition of grip strength or usual walking pace to existing risk scores results in improved CVD risk prediction, with an additive effect when both are added. As both these measures are cheap and easy to administer, these tools could provide an important addition to CVD risk screening, although further external validation is required., (Copyright © 2020 Mayo Foundation for Medical Education and Research.

Objective: To investigate the association of cardiorespiratory fitness with all-cause mortality, and cardiovascular disease (CVD), respiratory disease, chronic obstructive pulmonary disease (COPD) and cancer mortality and incidence., Design: Prospective population-based study., Setting: UK Biobank., Participants: Of the 5 02 628 (5.5% response rate) participants recruited by UK Biobank, we included 73 259 (14.6%) participants with available data in this analysis. Of these, 1374 participants died and 4210 developed circulatory diseases, 1293 respiratory diseases and 4281 cancer, over a median of 5.0 years (IQR 4.3-5.7) follow-up., Main Outcome Measures: All-cause mortality and circulatory disease, respiratory disease, COPD and cancer (such as colorectal, lung, breast and prostate) mortality/incidence. Fitness was estimated using a submaximal cycle ergometer test., Results: The HR for all-cause mortality for each metabolic equivalent of task (MET) higher fitness was 0.96 (95% CI 0.93 to 0.98). Similar results were observed for incident circulatory disease (HR 0.96 [0.95 to 0.97]), respiratory disease (HR 0.96 [0.94 to 0.98]), COPD (HR 0.90 [0.86 to 0.95) and colorectal cancer (HR 0.96 [0.92 to 1.00]). Nonlinear analysis revealed that a high level of fitness (>10METs) was associated with a greater incidence of atrial fibrillation (HR 1.24 [1.07 to 1.44]) and prostate cancer (HR 1.16 [1.02 to 1.32]) compared with average fitness. All results were adjusted for sociodemographic, lifestyle and dietary factors, body composition, and morbidity at baseline and excluded events in the first 2 years of follow-up., Conclusions: Higher cardiorespiratory fitness was associated with lower risk of premature mortality and incidence of CVD, respiratory disease and colorectal cancer., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Objective: To investigate the associations of objectively measured cardiorespiratory fitness (CRF) and grip strength (GS) with incident heart failure (HF), a clinical syndrome that results in substantial social and economic burden, using UK Biobank data., Patients and Methods: Of the 502,628 participants recruited into the UK Biobank between April 1, 2007, and December 31, 2010, a total of 374,493 were included in our GS analysis and 57,053 were included in CRF analysis. Associations between CRF and GS and incident HF were investigated using Cox proportional hazard models, with adjustment for known measured confounders., Results: During a mean of 4.1 (range, 2.4-7.1) years, 631 HF events occurred in those with GS data, and 66 HF events occurred in those with CRF data. Higher CRF was associated with 18% lower risk for HF (hazard ratio [HR], 0.82; 95% CI, 0.76-0.88) per 1-metabolic equivalent increment increase and GS was associated with 19% lower incidence of HF risk (HR, 0.81; 95% CI, 0.77-0.86) per 5-kg increment increase. When CRF and GS were standardized, the HR for CRF was 0.50 per 1-SD increment (95% CI, 0.38-0.65), and for GS was 0.65 per 1-SD increment (95% CI, 0.58-0.72)., Conclusion: Our data indicate that objective measurements of physical function (GS and CRF) are strongly and independently associated with lower HF incidence. Future studies targeting improving CRF and muscle strength should include HF as an outcome to assess whether these results are causal., (Copyright © 2019 Mayo Foundation for Medical Education and Research.

Background: higher grip strength is associated with better health outcomes. The optimal way to report grip strength (i.e. absolute vs. relative) for prediction, however, remains to be established., Methods: in participants (aged 37-73 at baseline) from the UK Biobank, we examined the associations of grip strength, expressed in absolute terms (kilograms) and relative to anthropometric variables, with mortality and disease incidence, after exclusion of the first 2 years of follow-up, and compared risk predictions scores of handgrip strength when differentially expressed., Results: of the 356 721 participants included in the analysis 6,234 died (1.7%) and 4,523 developed CVD (1.3%) over a mean follow-up of 5.0 years (ranging from 3.3 to 7.8) for mortality and 4.1 years (ranging from 2.4 to 7.0) for disease incidence data. As expected, baseline higher grip strength was associated with lower risk of all-cause and cause specific mortality and incidence. These associations did not meaningfully differ when grip-strength was expressed in absolute terms, vs. relative to height, weight, fat-free mass, BMI, fat-free mass index and fat-free mass, or as z-scores. Similarly the different ways of expressing grip strength had little effect on the ability of grip strength to improve risk prediction, based on C-index change, of an office-based risk score., Conclusions: the ability of grip strength to predict mortality is not altered by changing how it is expressed., (© The Author(s) 2019.

Aims: Myocardial infarction (MI) is among the commonest attributable risk factors for heart failure (HF). We compared clinical characteristics associated with the progression to HF in patients with or without a history of MI in the HOMAGE cohort and validated our results in UK Biobank. Methods and results: During a follow‐up of 5.2 (3.5–5.9) years, 177 (2.4%) patients with prior MI and 370 (1.92%) patients without prior MI experienced HF onset in the HOMAGE cohort (n = 26 478, history of MI: n = 7241). Older age, male sex and higher heart rate were significant risk factors of HF onset in patients with and without prior MI. Lower renal function was more strongly associated with HF onset in patients with prior MI. Higher body mass index (BMI), systolic blood pressure and blood glucose were significantly associated with HF onset only in patients without prior MI (all p for interactions <0.05). In the UK Biobank (n = 500 001, history of MI: n = 4555), higher BMI, glycated haemoglobin, diabetes and hypertension had a stronger association with HF onset in participants without prior MI compared to participants with MI (all p for interactions <0.05). Conclusion: The importance of clinical risk factors associated with HF onset is dependent on whether the patient has had a prior MI. Diabetes and hypertension are associated with new‐onset HF only in the absence of MI history. Patients may benefit from targeted risk management based on MI history. [ABSTRACT FROM AUTHOR]

Background: Abdominal aortic aneurysm (AAA) can occur in patients who are ineligible for routine ultrasound screening. A simple AAA risk score was derived and compared with current guidelines used for ultrasound screening of AAA.Methods: United Kingdom Biobank participants without previous AAA were split into a derivation cohort (n=401 820, 54.6% women, mean age 56.4 years, 95.5% White race) and validation cohort (n=83 816). Incident AAA was defined as first hospital inpatient diagnosis of AAA, death from AAA, or an AAA-related surgical procedure. A multivariable Cox model was developed in the derivation cohort into an AAA risk score that did not require blood biomarkers. To illustrate the sensitivity and specificity of the risk score for AAA, a theoretical threshold to refer patients for ultrasound at 0.25% 10-year risk was modeled. Discrimination of the risk score was compared with a model of US Preventive Services Task Force (USPSTF) AAA screening guidelines.Results: In the derivation cohort, there were 1570 (0.40%) cases of AAA over a median 11.3 years of follow-up. Components of the AAA risk score were age (stratified by smoking status), weight (stratified by smoking status), antihypertensive and cholesterol-lowering medication use, height, diastolic blood pressure, baseline cardiovascular disease, and diabetes. In the validation cohort, over 10 years of follow-up, the C-index for the model of the USPSTF guidelines was 0.705 (95% CI, 0.678-0.733). The C-index of the risk score as a continuous variable was 0.856 (95% CI, 0.837-0.878). In the validation cohort, the USPSTF model yielded sensitivity 63.9% and specificity 71.3%. At the 0.25% 10-year risk threshold, the risk score yielded sensitivity 82.1% and specificity 70.7% while also improving the net reclassification index compared with the USPSTF model +0.176 (95% CI, 0.120-0.232). A combined model, whereby risk scoring was combined with the USPSTF model, also improved prediction compared with USPSTF alone (net reclassification index +0.101 [95% CI, 0.055-0.147]).Conclusions: In an asymptomatic general population, a risk score based on patient age, height, weight, and medical history may improve identification of asymptomatic patients at risk for clinical events from AAA. Further development and validation of risk scores to detect asymptomatic AAA are needed. [ABSTRACT FROM AUTHOR]
