This umbrella review synthesised evidence from 35 meta-analyses encompassing 154 randomised controlled trials (11 newly included) and 78,175 participants to evaluate the clinical effects of calcium (Ca) and calcium plus vitamin D (CaD) supplementation on cardio-cerebrovascular outcomes and metabolic parameters. Data extracted from Embase, Web of Science, PubMed, and Cochrane Library (inception to 31 January 2025) revealed divergent outcomes: Ca supplementation demonstrated reductions in diastolic blood pressure, body fat, total cholesterol, and total/high-density lipoprotein (HDL) cholesterol ratio but was associated with increased cardio-cerebrovascular disease risk, elevated inflammatory markers (IL-6, TNF-α), two-hour postload glycemia, and waist-to-hip ratio. Conversely, CaD supplementation showed beneficial regulation of cardiovascular risk factors including decreased body fat, body mass index, fasting blood glucose, and improved lipid profiles (low-density lipoprotein, HDL, non-HDL, and total/HDL cholesterol ratios), whereas no significant effects were observed on cardio-cerebrovascular disease incidence. Limitations included exclusion of studies with an unspecified calcium source and suboptimal evidence quality. Taken together, these findings suggest that CaD supplementation may confer a more favourable cardiometabolic profile than Ca supplementation alone. Because several clinical event outcomes were supported by low-certainty evidence, the potential benefits and risks of calcium supplementation should be weighed carefully in individualised clinical decision-making.
The effect of alcohol consumption on atrial fibrillation risk remains controversial. Evaluating the association of alcohol consumption with atrial fibrillation-related biomarkers may help better understand the relevant mechanistic underpinnings. We studied participants from the PREDIMED-Plus study, a weight-loss randomised trial in metabolically unhealthy adults. N-terminal pro-B-type natriuretic protein, high-sensitivity troponin-T (hsTnT), high-sensitivity C-reactive protein (hsCRP), 3-nitrotyrosine and procollagen type 1 carboxy-terminal propeptide were measured in serum at baseline and years 3 and 5 of follow-up. We calculated average alcohol consumption in drinks/d (1 drink = 14 grams alcohol) with validated FFQ. Using multivariable models, we estimated cross-sectional and longitudinal associations of alcohol consumption with log-transformed biomarkers. Among 523 participants (mean age (sd): 65·1 (4·9) years, 40 % female), mean alcohol consumption was 1 drink/d. Cross-sectionally, alcohol consumption was not associated with cardiac biomarkers. Longitudinally, compared with non-consumers, heavy drinkers at baseline (≥ 4 drinks/d) had smaller increases in hsTnT (β: −0·10, 95 % CI: −0·20, 0·00) over 5 years. In contrast, those who increased alcohol consumption over follow-up experienced greater increases in hsCRP (β: 0·31, 95 % CI: 0·00, 0·63) compared with those whose drinking behaviour stayed the same. In this high-risk population, higher baseline alcohol intake was associated with smaller increases in hsTnT over follow-up while increases in alcohol intake over time were associated with higher levels of systemic inflammation. These findings highlight the importance of considering longitudinal changes in average alcohol exposure when evaluating its relationship with cardiometabolic biomarkers.
Days alive out-of-hospital (DAOOH) is a well-accepted outcome in clinical research, as it summarizes both hospitalization and mortality. However, its distribution is often skewed, making accurate modeling challenging in practice. We utilized data from a randomized trial to discuss estimands and statistical methods of interest for DAOOH.
Methods:
We examined several estimands and statistical models targeting these estimands, including linear regression, gamma regression, ordinal regression, and the probabilistic index model. Comparison was based on interpretability, precision, and model fit. We adopted G-computation to assess causal effects leveraging different regression models to target a simple unified estimand.
Results:
For unadjusted analyses, the Mann–Whitney U-test is a simple and assumption-light approach, which can be paired with a probabilistic index to enhance interpretation. For adjusted analyses, while the mean difference and mean ratio are intuitive, the methods targeting them (linear and gamma regression) showed sub-optimal model fit. Conversely, ordinal regression showed a superior fit, but its odds ratio estimand is difficult to interpret. Pairing gamma or ordinal regression with g-computation facilitates estimation of a marginal causal mean difference estimand under certain assumptions, allowing for both a good model fit and interpretability.
Conclusions:
Our findings illustrate trade-offs of estimands and model choices for DAOOH, providing guidance for method selection. Based on data from this randomized trial, the Mann–Whitney U-test is recommended for unadjusted analyses. Ordinal regression paired with g-computation provides the best balance of precision, model fit, and interpretability to report an adjusted effect.
The Mediterranean Diet (Med Diet) has long been shown to be associated with lower cardiovascular mortality in epidemiological studies. However, the direct effect of the dietary pattern on cardiovascular risk factors is less clear. Furthermore, the effect of Med Diet interventions in non-Mediterranean populations on cardiovascular and metabolic risk is variable. A Cochrane Review in 2019 concluded there was low to moderate evidence of a modest benefit but noted that there were still ongoing trials. Since 2019, there have been a number of published trials that have not shown a benefit of the Med Diet over other interventions or usual care. It is possible that dietary factors such as quality or quantity of carbohydrate and energy restriction are more important factors, along with the degree of weight loss, than the Med Diet itself. There are also many other factors that influence the uptake and effectiveness of the Med Diet in populations that have a different traditional or habitual diet. This review paper examines a selection of 20 Med Diet intervention trials specifically looking at clinical outcomes of glucose metabolism: fasting plasma glucose, HbA1c, development of type 2 diabetes or need for hypoglycaemic medications, with or without other cardiometabolic risk factors. These trials are a mix of randomised controlled trials, crossover studies and cohort studies of greater than 8 weeks duration with more than 25 participants. There is heterogeneity in study designs and outcomes, making comparison difficult, but there is no clear benefit of the Med Diet presented.
Persistent discrimination and identity threats contribute to adverse health outcomes in minoritized groups, mediated by both structural racism and physiological stress responses.
Objective:
This study aims to evaluate the feasibility of recruiting African American volunteers for a pilot study of race-based stress, the acceptability of a mindfulness intervention designed to reduce racism-induced stress, and to evaluate preliminary associations between race-based stress and clinical, psychosocial, and biological measures.
Methods:
A convenience sample of African Americans aged 18–50 from New York City’s Tri-state area underwent assessments for racial discrimination using the Everyday Discrimination Scale (EDS) and Race-Based Traumatic Stress Symptom Scale. Mental health was evaluated using validated clinical scales measuring depression, anxiety, stress, resilience, mindfulness, resilience, sleep, interpersonal connection, and coping. Biomarkers were assessed through clinical laboratory tests, allostatic load assessment, and blood gene expression analysis.
Results:
Twenty participants (12 females, 8 males) completed assessments after consent. Elevated EDS scores were associated with adverse lipid profiles, including higher cholesterol/high-density lipoprotein (HDL) ratios and lower HDL levels, as well as elevated inflammatory markers (NF-kB activity) and reduced antiviral response (interferon response factor). Those with high EDS reported poorer sleep, increased substance use, and lower resilience. Mindfulness was positively associated with coping and resilience but inversely to sleep disturbance. 90% showed interest in a mindfulness intervention targeting racism-induced stress.
Conclusions:
This study demonstrated an association between discrimination and adverse health effects among African Americans. These findings lay the groundwork for further research to explore the efficacy of mindfulness and other interventions on populations experiencing discrimination.
It is estimated that more than one-tenth of adults aged ≥60 years are now classified as having sarcopenic obesity (SO), a clinical condition characterised by the concurrent presence of sarcopenia (low muscle mass and weakness) and obesity (excessive fat mass). Independently, sarcopenia and obesity are associated with a high risk of numerous adverse health outcomes including CVD and neurological conditions (e.g. dementia), but SO may confer a greater risk, exceeding either condition alone. This imposes a substantial burden on individuals, healthcare systems and society. In recent years, an increasing number of observational studies have explored the association between SO and the risk of CVD; however, results are mixed. Moreover, the pathophysiology of SO is governed by a complex interplay of multiple mechanisms including insulin resistance, inflammation, oxidative stress, hormonal shifts and alteration of energy balance, which may also play a role in the occurrence of various CVD. Yet, the exact mechanisms underlying the pathological connection between these two complex conditions remain largely unexplored. The aim of this review is to examine the association between SO and CVD. Specifically, we seek to: (1) discuss the definition, epidemiology and diagnosis of SO; (2) reconcile previously inconsistent findings by synthesising evidence from longitudinal studies on the epidemiological link between SO and CVD and (3) discuss critical mechanisms that may elucidate the complex and potentially bidirectional relationships between SO and CVD.
The Cardiovascular Health Diet Index (CHDI) is a diet quality score based on the dietary guidelines of the American Heart Association for cardiovascular health but with some adaptations, such as red meat, dairy products, beans and ultra-processed foods in its components. The CHDI has shown good relative validity parameters; however, its association with health outcomes is still unclear. Thus, our aim was to investigate the association between the CHDI score with subclinical atherosclerosis. Data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort were used. Subclinical atherosclerosis was assessed by measuring coronary artery calcification at baseline (2008–2010) and second wave (2012–2014) and carotid intima-media thickness at baseline and at the third wave (2017–2019). The CHDI score (ranges from 0 to 110 points) was applied to dietary data obtained from an FFQ at baseline. Poisson regression with robust variance, linear regression and linear mixed-effects models were used to evaluate the association of the CHDI score with coronary artery calcification incidence (n 2224), coronary artery calcification progression (n 725) and changes in carotid intima-media thickness (n 7341) over time, respectively. After a median 8-year follow-up period, a 10-point increase in the CHDI score was associated with a decrease in carotid intima-media thickness of 0·002 mm (95 % CI –0·005, –0·001). No association was observed between the CHDI score and coronary artery calcification incidence and progression after a 4-year follow-up period. Higher scores in the CHDI were prospectively associated with decreased subclinical atherosclerosis after an 8-year follow-up period.
Many formerly incarcerated people have civil legal needs that can imperil their successful re-entry to society and, consequently, their health. We categorize these needs and assess their association with cardiovascular disease risk factors in a sample of recently released people. We find that having legal needs related to debt, public benefits, housing, or healthcare access is associated with psychosocial stress, but not uncontrolled high blood pressure or high cholesterol, in the first three months after release.
Throughout our lives, our brains undergo a process of gradual, ongoing, and highly variable modifications. It is perfectly normal for people to notice slight cognitive changes by their 50s. This chapter explains how our brain changes throughout our life span. New research on dementia has good news. Just like incidence of heart disease is going down, the incidence of dementia going down! Prevalence, however, or total number of cases, is going up, because there are more older adults in the population than ever before. Research shows life-long healthy habits may cut dementia risk by at least 1/3. Employing healthy habits at age 50 reduces our risk for dementia for at least 24 years. People in Blue Zones develop dementia at a 75% lower rate. Chapter explains the top ten practices to keep brain healthy and high functioning throughout life. Pushing yourself to learn something new helps you develop new neurons and new neural connections. Actions to take explained: Exercise, Mediterranean Diet, participate in Cognitive Training/Stimulation. Engage in creative pursuits. Sleep. Be mindful of medications. Higher education. Wear hearing aids. Watch heath. Avoid social isolation. Celebrate a healthy aging brain.
Common carotid intima-media thickness (ccIMT) progression is a risk marker for cardiovascular disease (CVD), whereas healthy lifestyle habits are associated with lower ccIMT. The objective of the present study was to test whether a healthy lifestyle intervention can beneficially affect ccIMT progression. A community-based non-randomised, controlled lifestyle intervention was conducted, focusing on a predominantly plant-based diet (strongest emphasis), physical activity, stress management and social health. Assessments of ccIMT were made at baseline, 6 months and 1 year. Participants had an average age of 57 years and were recruited from the general population in rural northwest Germany (intervention: n 114; control: n 87). From baseline to 1 year, mean ccIMT significantly increased in both the intervention (0⋅026 [95 % CI 0⋅012, 0⋅039] mm) and control group (0⋅045 [95 % CI 0⋅033, 0⋅056] mm). The 1-year trajectory of mean ccIMT was lower in the intervention group (P = 0⋅022; adjusted for baseline). In a subgroup analysis with participants with high baseline mean ccIMT (≥0⋅800 mm), mean ccIMT non-significantly decreased in the intervention group (−0⋅016 [95 % CI −0⋅050, 0⋅017] mm; n 18) and significantly increased in the control group (0⋅065 [95 % CI 0⋅033, 0⋅096] mm; n 12). In the subgroup, the 1-year trajectory of mean ccIMT was significantly lower in the intervention group (between-group difference: −0⋅051 [95 % CI −0⋅075, −0⋅027] mm; P < 0⋅001; adjusted for baseline). The results indicate that healthy lifestyle changes may beneficially affect ccIMT within 1 year, particularly if baseline ccIMT is high.
Whey protein (WP) has been heavily appreciated as a rich source of bioactive peptides, with potential benefits for cardiovascular health. This study constitutes a systematic review and meta-analysis summarising the effects of WP consumption on vascular reactivity, arterial stiffness and circulatory biomarkers of vascular function. We searched electronic databases, including PubMed, SCOPUS and Web of science for relevant articles from inception to July 2020. Original clinical trials published in English-language journals that investigated the effects of WP on vascular function were eligible. A total of 720 records were identified in the initial search; from these, sixteen were included in our systematic review and thirteen in meta-analysis. The pooled analysis of six studies showed a significant increase in flow-mediated dilation (FMD) after WP consumption (weighted mean differences (WMD): 1·09 %, 95 % CI: 0·17, 2·01, P= 0·01). Meta-analysis of available data did not show any significant reduction in arterial stiffness measures including augmentation index (effect sizes: 7, WMD: −0·29 %, 95 % CI: −1·58, 0·98, P= 0·64) and pulse wave velocity (effect sizes: 4, WMD: −0·72 m/s, 95 % CI: −1·47, 0·03, P= 0·06). Moreover, the pooled analysis of six effect sizes showed no significant effects on plasma levels of nitric oxide following WP supplementation (WMD: 0·42 μmol/l, 95 % CI: −0·52, 1·36, P= 0·38). The overall results provided evidence supporting a protective effect of WP on endothelial function measured by FMD, but not for arterial stiffness measures and circulatory biomarker of vascular function. Further research is required to substantiate the benefits of WP on vascular function.
Cardiovascular diseases are the leading causes of morbidity and mortality. Overweight, obesity, and accelerated growth during early childhood have been associated with adverse cardiovascular outcomes in later life. Few studies have assessed whether trajectories of accelerated growth in early childhood are associated with preclinical cardiovascular measurements. We aimed to evaluate the associations between childhood body mass index (BMI) growth trajectories and measures of macro- and microvascular function in early adolescence. Measurements of macrovascular function (systolic and diastolic blood pressure (SBP and DBP), pulse wave velocity (PWV), and microvascular function (central retinal arteriolar/veinular equivalent) were assessed at 11 years old in a Spanish birth cohort study (n = 489). BMI trajectories from birth to 9 years were identified using latent class growth analysis. Multiple linear regression assessed the associations between the BMI trajectories and macro- and microvascular function. Compared to children with average birth size and slower BMI gain (reference), children with a lower birth size and accelerated BMI gain had increased SBP [β = 6.57; (95% CI 4.00, 9.15)], DBP [β = 3.65; (95% CI 1.45, 5.86)], and PWV [β = 0.14; (95% CI 0.01, 0.27)]. Children with higher birth size and accelerated BMI gain had increased SBP [β = 4.75; (95% CI 1.79, 7.71) compared to the reference. No significant associations between BMI trajectories and the microvascular measurements were observed. In conclusion, we found that childhood BMI trajectories characterized by accelerated growth are associated with preclinical macrovascular measurements in young adolescents.
Fasting has been a practice among followers of different religions for many years. Christian Orthodox Church (COC) fasting is a periodic vegetarian-type diet in which seafood and snails are allowed on most fasting days. The present scoping review aimed to present available data regarding the benefits of COC fasting on metabolic syndrome (MetS) risk factors. Databases were searched for available studies. Twenty publications, with a total of 1226 fasting participants, provided data on the effects on different variables of MetS, including blood pressure, blood lipids and anthropometric measurements. Fasters’ diet is characterised by low saturated and trans fat intake, high complex carbohydrate and fibre consumption, due to permissible foods. COC fasting has no deficiency in essential amino acid intake since seafood and snails are allowed on fasting days. Fasters have healthier blood lipid profiles during and after COC fasting periods, and total cholesterol, LDL-cholesterol, systolic blood pressure, body weight and BMI are reduced after a fasting period. Due to restricted or forbidden intake of specific foods during the COC fasting periods, one might expect that fasters have reduced intake of macro- and micronutrients, but as shown in the available literature, there are no deficiencies. Future research on COC fasting is needed in areas not investigated at all, like MetS, before reaching definite conclusions.
This study assesses the association between living in a food desert and cardiovascular health risk among young adults in the USA, as well as evaluates whether personal and area socioeconomic status moderates this relationship.
Design:
A cross-sectional analysis was performed using data from Wave I (1993–1994) and Wave IV (2008) from the National Longitudinal Study of Adolescent to Adult Health. Ordinary least squares regression models assessing the association between living in a food desert and cardiovascular health were performed. Mediation and moderation analyses assessed the degree to which this association was conditioned by area and personal socioeconomic status.
Setting:
Sample of respondents living in urban census tracts in the USA in 2008.
Participants:
Young adults (n 8896) aged 24–34 years.
Results:
Net of covariates living in a food desert had a statistically significant association with cardiovascular health risk (range 0–14) (β = 0·048, P < 0·01). This association was partially mediated by area and personal socioeconomic status. Further analyses demonstrate that the adverse association between living in a food desert and cardiovascular health is concentrated among low socioeconomic status respondents.
Conclusions:
The findings from this study suggest a complex interplay between food deserts and economic conditions for the cardiovascular health of young adults. Developing interventions that aim to improve health behaviour among lower-income populations may yield benefits for preventing the development of cardiovascular health problems.
We examined whether breakfast frequency was associated with chronic inflammatory, as assessed by high-sensitivity C-reactive protein (CRP) concentration.
Design:
Cross-sectional study.
Setting:
Kailuan community, China.
Participants:
Included were 70 092 Chinese adults without CVD and cancer in 2014 with CRP concentrations <10 mg/l, when breakfast frequency was assessed via a questionnaire, and plasma CRP concentration was measured.
Results:
Breakfast frequency was associated with CRP concentration (P-trend < 0·001). The adjusted mean CRP was 1·33 mg/l (95 % CI 1·23, 1·44) for the ‘no breakfast’ group and 1·07 mg/l (95 % CI 1·0, 1·14) for the ‘breakfast everyday’ group (P-difference < 0·001), adjusting for age, sex, diet quality, total energy, obesity, education, occupation, marital status, smoking, alcohol consumption, blood pressure, sleep parameters, fasting blood glucose and lipid profiles. Consistently, the adjusted OR for CRP ≥ 1·0 mg/l and CRP ≥ 3·0 mg/l were 1·86 (95 % CI 1·73, 2·00) and 1·27 (95 % CI 1·15, 1·40), respectively, when comparing these two breakfast consumption groups (P-trend < 0·001 for both). The associations were more pronounced among older adults, relative to those who were younger (P-interaction < 0·001). Significant association between breakfast skipping and elevated CRP concentration was observed in those with poor diet quality, but not those with good diet quality.
Conclusions:
Habitually skipping breakfast is associated with elevated concentrations of CRP. Future prospective studies including repeated assessment of inflammatory biomarkers and a collection of detailed information on type and amount of breakfast foods are warranted.
The Mediterranean diet offers a range of health benefits. However, previous studies indicate that the restricted consumption of red meat in the diet may affect long-term sustainability in non-Mediterranean countries. A 24-week randomised controlled parallel cross-over design compared a Mediterranean diet supplemented with 2–3 serves per week of fresh, lean pork (MedPork) with a low-fat control diet (LF). Thirty-three participants at risk of CVD followed each intervention for 8 weeks, with an 8-week washout period separating interventions. The primary outcome was home-measured systolic blood pressure. Secondary outcomes included diastolic blood pressure, fasting lipids, glucose, insulin, C-reactive protein (CRP), body composition and dietary adherence. During the MedPork intervention, participants achieved high adherence to dietary guidelines. Compared with the MedPork intervention, the LF intervention led to greater reductions in weight (Δ = −0·65; 95 % CI −0·04, −1·25 kg, P = 0·04), BMI (Δ = −0·25; 95 % CI −0·03, −0·47 kg/m2, P = 0·01) and waist circumference (Δ = −1·40; 95 % CI −0·45, −2·34 cm, P < 0·01). No significant differences were observed for blood pressure, lipids, glucose, insulin or CRP. These findings indicate that Australians are capable of adhering to a Mediterranean diet with 2–3 weekly serves of fresh, lean pork. Larger intervention studies are now required to demonstrate clinical efficacy of the diet in populations with elevated blood pressure.
The Developmental Origins of Disease hypothesis has spurred increased interest in how prenatal exposures affect lifelong health, while mechanisms such as epigenetics may explain the multigenerational influences on health. Such factors are not well captured within conventional epidemiologic study designs. We explored the feasibility of collecting information on the offspring and grand-offspring of participants in a long-running study.
Design:
The Bogalusa Heart Study is a study, begun in 1973, of life-course cardiovascular health in a semirural population (65% white and 35% black).
Main measures:
Female participants who had previously provided information on their pregnancies were contacted to obtain contact information for their daughters aged 12 and older. Daughters were then contacted to obtain reproductive histories, and invited for a clinic or lab visit to measure cardiovascular risk factors.
Results:
Two hundred seventy-four daughters of 208 mothers were recruited; 81% (223) had a full clinic visit and 19% (51) a phone interview only. Forty-five percent of the daughters were black, and 55% white. Mean and median age at interview was 27, with 15% under the age of 18. The strongest predictors of participation were black race, recent maternal participation in the parent study, and living in or near Bogalusa. Simple correlations for cardiovascular risk factors across generations were between r = 0.19 (systolic blood pressure) and r = 0.39 (BMI, LDL).
Conclusion:
It is feasible to contact the children of study participants even when participants are adults, and initial information on the grandchildren can also be determined in this manner.
Emergency Medical Services (EMS) professionals face high physical demands in high-stress settings; however, the prevalence of cardiovascular health (CVH) risk factors in this health care workforce has not been explored. The primary objective of this study was to compare the distribution of CVH and its individual components between a sample of emergency medical technicians (EMTs) and paramedics. The secondary objective was to identify associations between demographic and employment characteristics with ideal CVH in EMS professionals.
Methods:
A cross-sectional survey based on the American Heart Association’s (AHA; Dallas, Texas USA) Life’s Simple 7 (LS7) was administered to nationally-certified EMTs and paramedics. The LS7 components were scored according to previously described cut points (ideal = 2; intermediate = 1; poor = 0). A composite CVH score (0-10) was calculated from the component scores, excluding cholesterol and blood glucose due to missing data. Multivariable logistic regression was used to estimate odds ratios (OR; 95% CI) for demographic and employment characteristics associated with optimal CVH (≥7 points).
Results:
There were 24,708 respondents that were currently practicing and included. More EMTs achieved optimal CVH (n = 4,889; 48.8%) compared to paramedics (n = 4,338; 40.6%). Factors associated with higher odds of optimal CVH included: higher education level (eg, college graduate or more: OR = 2.26; 95% CI, 1.97-2.59); higher personal income (OR = 1.26; 95% CI, 1.17-1.37); and working in an urban versus rural area (OR = 1.31; 95% CI, 1.23-1.40). Paramedic certification level (OR = 0.84; 95% CI, 0.78-0.91), older age (eg, 50 years or older: OR = 0.65; 95% CI, 0.58-0.73), male sex (OR = 0.54; 95% CI, 0.50-0.56), working for a non-fire-based agency (eg, private service: OR = 0.68; 95% CI, 0.62-0.74), and providing medical transport service (OR = 0.81; 95% CI, 0.69-0.94) were associated with lower odds of optimal CVH.
Conclusions:
Several EMS-related characteristics were associated with lower odds of optimal CVH. Future studies should focus on better understanding the CVH and metabolic risk profiles for EMS professionals and their association with incident cardiovascular disease (CVD), major cardiac events, and occupational mortality.

Centenarians have survived into very late life, but whether they reach very old age in good health remains unclear. The purpose of this study was to compare the cardiovascular health status and cognitive functioning of centenarians in the United States with centenarians in Japan.
Design, Setting, and Participants:
This cross-national design compared centenarians from the United States and Japan. The sample of U.S. centenarians was recruited from the Georgia Centenarian Study and included 287 centenarians. The sample of Japanese centenarians was recruited from the Tokyo Centenarian Study and included 304 centenarians.
Measurements:
Cognitive functioning was assessed with a mental status questionnaire, and cardiovascular disease by a health history assessment, blood pressure, and selected blood parameters.
Results:
The results suggest that Tokyo centenarians had lower disease experiences and BMI values, when compared to Georgia centenarians, but blood pressure was higher among Japanese centenarians. Lower levels of hemoglobin in Japanese centenarians and higher levels of C-reactive protein in Georgia were also found. The positive association of hypertension and albumin levels with cognitive functioning and the negative association of stroke occurrence with cognitive functioning were replicated in both countries. Differential effects were obtained for heart problems, BMI, and C-reactive protein (with positive effects for Tokyo centenarians, except for C-reactive protein).
Conclusion:
For extremely old individuals, some markers of cardiovascular disease are replicable across countries, whereas differential effects for cardiovascular health also need to be considered in cardiovascular health.
Americans consume Na in excess of daily recommendations. Most dietary Na comes from packaged foods, and bread is a major contributor. In the UK, national Na reduction strategies contributed to lower Na levels in packaged foods and lower population Na intake. Similar initiatives are emerging in the USA and require surveillance to assess effectiveness. We aimed to examine Na levels in bread products in the USA and compare levels with similar UK products.
Design
Na data for bread products were obtained from the US Label Insight Open Data Initiative (n 4466) and the FoodSwitch UK database (n 1651). Mean, median and range of Na content, and proportion of products meeting Na targets established by the National Salt Reduction Initiative (NSRI) and the UK Department of Health (DH) were calculated overall, by bread type and by country.
Results
Mean (sd) Na content in bread was 455 (170) mg/100 g in the USA and 406 (179) mg/100 g in the UK. In both countries, savoury bread had the highest mean Na (USA=584 mg/100 g, UK=543 mg/100 g) and fruit bread the lowest mean Na (USA=345 mg/100 g, UK=277 mg/100 g). Na content of US bread products was 12 % higher than in the UK, with 21 % of US bread products and 31 % of UK bread products meeting the NSRI and DH targets, respectively.
Conclusions
US bread products have, on average, 12 % more Na than similar products in the UK. Variation in Na content within product categories, and between countries, suggests the feasibility of manufacturing products with lower Na to lower dietary Na intake.
