Meat consumption and incident type 2 diabetes: an individual-participant federated meta-analysis of 1·97 million adults with 100 000 incident cases from 31 cohorts in 20 countries.

BACKGROUND: Meat consumption could increase the risk of type 2 diabetes. However, evidence is largely based on studies of European and North American populations, with heterogeneous analysis strategies and a greater focus on red meat than on poultry. We aimed to investigate the associations of unprocessed red meat, processed meat, and poultry consumption with type 2 diabetes using data from worldwide cohorts and harmonised analytical approaches. METHODS: This individual-participant federated meta-analysis involved data from 31 cohorts participating in the InterConnect project. Cohorts were from the region of the Americas (n=12) and the Eastern Mediterranean (n=2), European (n=9), South-East Asia (n=1), and Western Pacific (n=7) regions. Access to individual-participant data was provided by each cohort; participants were eligible for inclusion if they were aged 18 years or older and had available data on dietary consumption and incident type 2 diabetes and were excluded if they had a diagnosis of any type of diabetes at baseline or missing data. Cohort-specific hazard ratios (HRs) and 95% CIs were estimated for each meat type, adjusted for potential confounders (including BMI), and pooled using a random-effects meta-analysis, with meta-regression to investigate potential sources of heterogeneity. FINDINGS: Among 1 966 444 adults eligible for participation, 107 271 incident cases of type 2 diabetes were identified during a median follow-up of 10 (IQR 7-15) years. Median meat consumption across cohorts was 0-110 g/day for unprocessed red meat, 0-49 g/day for processed meat, and 0-72 g/day for poultry. Greater consumption of each of the three types of meat was associated with increased incidence of type 2 diabetes, with HRs of 1·10 (95% CI 1·06-1·15) per 100 g/day of unprocessed red meat (I2=61%), 1·15 (1·11-1·20) per 50 g/day of processed meat (I2=59%), and 1·08 (1·02-1·14) per 100 g/day of poultry (I2=68%). Positive associations between meat consumption and type 2 diabetes were observed in North America and in the European and Western Pacific regions; the CIs were wide in other regions. We found no evidence that the heterogeneity was explained by age, sex, or BMI. The findings for poultry consumption were weaker under alternative modelling assumptions. Replacing processed meat with unprocessed red meat or poultry was associated with a lower incidence of type 2 diabetes. INTERPRETATION: The consumption of meat, particularly processed meat and unprocessed red meat, is a risk factor for developing type 2 diabetes across populations. These findings highlight the importance of reducing meat consumption for public health and should inform dietary guidelines.

Life's Essential 8 in Relation to Cardiovascular Disease and Mortality in Individuals With Diabetes.

Background: Evidence regarding the potential health effects of Life's Essential 8 (LE8) score among individuals with type 2 diabetes (T2D) is limited. Objectives: The purpose of this study was to examine the associations of LE8 score with risk of cardiovascular disease (CVD) and mortality among individuals with T2D. Methods: We prospectively followed 19,915 Chinese participants with T2D at baseline or diagnosed during follow-up (Kailuan Study: 2006-2020), who were free of CVD at diagnosis of diabetes. Diet, lifestyle, and health conditions were repeatedly assessed every 2 years. The LE8 score (range 0-100), was calculated based on 8 components: diet quality, physical activity, smoking status, sleep health, body mass index, blood lipids, blood glucose, and blood pressure. We used time-varying cox models to model the associations. Results: During a median follow-up of 11.5 years in participants with T2D, there were 3,295 incident CVD cases and 3,123 deaths. Higher LE8 score was associated with lower risk of CVD incidence and total mortality among participants with diabetes. The multivariate-adjusted HRs for the highest quintile of LE8 score compared with the lowest quintile were 0.56 (95% CI: 0.53-0.59) for CVD, 0.57 (95% CI: 0.53-0.62) for heart disease, 0.53 (95% CI: 0.49-0.57) for stroke, and 0.73 (95% CI: 0.69-0.78) for total mortality (all P trend <0.001). Furthermore, compared with participants with stable or decreased LE8 score after diabetes diagnosis, those with increased LE8 score had 17% to 42% lower risk of CVD, heart disease, stroke, and mortality. Conclusions: A higher LE8 score was associated with a substantially lower risk of CVD incidence and total mortality among adults with T2D.

Association between density of food retailers and fitness centers and gestational diabetes mellitus in Eastern Massachusetts, USA: population-based study.

Background: Few studies have investigated the relationship between the food and physical activity environment and odds of gestational diabetes mellitus (GDM). This study quantifies the association between densities of several types of food establishments and fitness centers with the odds of having GDM. Methods: The density of supermarkets, fast-food restaurants, full-service restaurants, convenience stores and fitness centers at 500, 1000 and 1500 m (m) buffers was counted at residential addresses of 68,779 pregnant individuals from Eastern Massachusetts during 2000-2016. The 'healthy food index' assessed the relative availability of healthy (supermarkets) vs unhealthy (fast-food restaurants, convenience stores) food retailers. Multivariable logistic regression quantified the cross-sectional association between exposure variables and the odds of having GDM, adjusting for individual and area-level characteristics. Effect modification by area-level socioeconomic status (SES) was assessed. Findings: In fully adjusted models, pregnant individuals living in the highest density tertile of fast-food restaurants had higher GDM odds compared to those living in the lowest density tertile (500 m: odds ratio (OR):1.17 95% CI: [1.04, 1.31]; 1000 m: 1.33 95% CI: [1.15, 1.53]); 1500 m: 1.18 95% CI: [1.01, 1.38]). Greater residential density of supermarkets was associated with lower odds of GDM (1000 m: 0.86 95% CI: [0.74, 0.99]; 1500 m: 0.86 95% CI: [0.72, 1.01]). Similarly, living in the highest fitness center density tertile was associated with decreased GDM odds (500 m:0.87 95% CI: [0.76, 0.99]; 1500 m: 0.89 95% CI: [0.79, 1.01]). There was no evidence of effect modification by SES and no association found between the healthy food index and GDM odds. Interpretation: In Eastern Massachusetts, living near a greater density of fast-food establishments was associated with higher GDM odds. Greater residential access to supermarkets and fitness centers was associated with lower the odds of having GDM. Funding: NIH.

Relationship between COVID-19 pandemic-related experienced stress and lifestyle habits among university students from Québec, Canada.

Whether COVID-19-related experienced stress influenced lifestyle habits remains to be thoroughly evaluated among university students. This study examined the relationship between COVID-19-related experienced stress and subsequent lifestyle habits among undergraduate students. This cross-sectional study included 708 undergraduate students from Université Laval (Québec, Canada) participating in the Expériences Pandémiques (ExPan) cohort. Data on COVID-19-related experienced stress and lifestyle were self-reported using a questionnaire completed between February and April of 2022. A stress index (SI) was computed by summing scores associated with 31 situational statements related to the pandemic (e.g., not being able to see friends, dealing with job loss). A healthy lifestyle score (HLS) ranging from zero to seven was calculated based on seven lifestyle habits: moderate-to-vigorous physical activity, sleep quality, fruit and vegetable intake, tobacco and electronic cigarette use, alcohol consumption, cannabis use, and hard or sedative-hypnotic drugs use. In multivariable-adjusted models, a negative association between the SI and the HLS was found (ß10% increment SI = -0.23, 95% CI = -0.30, -0.16 HLS point; P < 0.0001). The SI was also negatively associated with sleep quality, and fruit and vegetable consumption, while being positively associated with at-risk alcohol consumption, cannabis use, and hard or sedative-hypnotic drug use. Subgroup analyses suggested a negative relationship between the SI and HLS among participants who did not receive academic accommodations (e.g., additional time for evaluations, personal notetaker), but not those who received such accommodations. This study suggests that COVID-19-related experienced stress was negatively associated with healthy lifestyle habits in this cohort of undergraduate students.

Substitution of dietary monounsaturated fatty acids from olive oil for saturated fatty acids from lard increases low-density lipoprotein apolipoprotein B-100 fractional catabolic rate in subjects with dyslipidemia associated with insulin resistance: a randomized controlled trial.

BACKGROUND: The substitution of monounsaturated acids (MUFAs) for saturated fatty acids (SFAs) is recommended for cardiovascular disease prevention but its impact on lipoprotein metabolism in subjects with dyslipidemia associated with insulin resistance (IR) remains largely unknown. OBJECTIVES: This study aimed to evaluate the impact of substituting MUFAs for SFAs on the in vivo kinetics of apolipoprotein (apo)B-containing lipoproteins and on the plasma lipidomic profile in adults with IR-induced dyslipidemia. METHODS: Males and females with dyslipidemia associated with IR (n = 18) were recruited for this crossover double-blind randomized controlled trial. Subjects consumed, in random order, a diet rich in SFAs (SFAs: 13.4%E; MUFAs: 14.4%E) and a diet rich in MUFAs (SFAs: 7.1%E; MUFAs: 20.7%E) in fully controlled feeding conditions for periods of 4 wk each, separated by a 4-wk washout. At the end of each diet, fasting plasma samples were taken together with measurements of the in vivo kinetics of apoB-containing lipoproteins. RESULTS: Substituting MUFAs for SFAs had no impact on triglyceride-rich lipoprotein apoB-48 fractional catabolic rate (FCR) (Δ = -8.9%, P = 0.4) and production rate (Δ = 0.0%, P = 0.9), although it decreased very low-density lipoprotein apoB-100 pool size (PS) (Δ = -22.5%; P = 0.01). This substitution also reduced low-density lipoprotein cholesterol (LDL-C) (Δ = -7.0%; P = 0.01), non-high-density lipoprotein cholesterol (Δ = -2.5%; P = 0.04), and LDL apoB-100 PS (Δ = -6.0%; P = 0.05). These differences were partially attributed to an increase in LDL apoB-100 FCR (Δ = +1.6%; P = 0.05). The MUFA diet showed reduced sphingolipid concentrations and elevated glycerophospholipid levels compared with the SFA diet. CONCLUSIONS: This study demonstrated that substituting dietary MUFAs for SFAs decreases LDL-C levels and LDL PS by increasing LDL apoB-100 FCR and results in an overall improved plasma lipidomic profile in individuals with IR-induced lipidemia. TRIAL REGISTRATION: This trial was registered as clinicaltrials.gov as NCT03872349.

Relationship Between Diet Quality and Statin Use Among Adults With Metabolic Syndrome From the CARTaGENE Cohort.

Background: In metabolic syndrome (MetS), cardiovascular disease (CVD) risk reduction relies on the complementary use of diet and lipid-lowering medication. Evidence suggests that initiating such medication may impede diet quality. The objective of this study was to evaluate the relationship between diet quality and statin use among adults with MetS and free of CVD from the Province of Québec. Methods: This cross-sectional study included 2481 adults with MetS (40-69 years of age) from the CARTaGENE Québec population-based cohort, of whom 463 self-reported using statin monotherapy. Diet was assessed using the Canadian Dietary History Questionnaire II, a food- frequency questionnaire, and diet quality was assessed using the Alternative Healthy Eating Index (AHEI). Results: In multivariable-adjusted linear regression models, statin users had lower AHEI (%) compared with nonusers (users: 40.0; 95% confidence interval [CI], 38.9, 41.2 vs nonusers: 41.2; 95% CI, 40.4, 42.0; P = 0.03] because of a lower consumption of vegetables and whole grains. Stratified interaction analyses showed that the lower diet quality among statin users was mostly prevalent among men aged ≥ 50 years and women aged ≥ 60 years, among individuals with annual household incomes of < $50,000 and persons who self-reported history of high blood pressure. Conclusions: In this cohort of adults with MetS from Quebéc, the use of statin monotherapy in primary prevention of CVD was associated with a slightly lower diet quality. These data suggest suboptimal complementarity between diet quality and use of cholesterol-lowering medication in primary prevention of CVD in MetS.

Contexte: Dans le syndrome métabolique, la réduction du risque de maladie cardiovasculaire repose sur la complémentarité entre une saine alimentation et l'utilisation d'hypolipidémiants. Des évidences suggèrent que l'initiation d'un traitement médicamenteux hypolipémiant influencerait négativement la qualité de l'alimentation. Cette étude avait pour objectif de déterminer la relation entre la qualité de l'alimentation et l'utilisation de statines chez des adultes avec un syndrome métabolique, mais sans maladie cardiovasculaire, au Québec. Méthodologie: Cette étude transversale comptait 2481 adultes avec un syndrome métabolique (âgés de 40 à 69 ans) provenant de la cohorte CARTaGENE, représentative de la population du Québec, dont 463 sujets ayant autodéclaré qu'ils prenaient une statine en monothérapie. L'alimentation des sujets a été évaluée à l'aide du Canadian Dietary History Questionnaire II, un questionnaire de fréquence alimentaire, et la qualité de l'alimentation a été évaluée à l'aide de l'Alternative Healthy Eating Index (AHEI). Résultats: Dans des modèles de régression linéaire multivariée, les utilisateurs de statines ont présenté un indice AHEI (%) plus faible en comparaison aux non-utilisateurs (utilisateurs : 40,0; intervalle de confiance [IC] à 95 % : 38,9-41,2 vs non-utilisateurs : 41,2; IC à 95 % : 40,4-42,0; p = 0,03), en raison d'une plus faible consommation de légumes et de grains entiers. Selon des analyses d'interaction stratifiées, la plus faible qualité nutritionnelle chez les utilisateurs de statines était particulièrement prévalente chez les hommes de ≥ 50 ans et les femmes de ≥ 60 ans, chez les personnes dont le revenu annuel du ménage était < 50 000 dollars et chez les personnes ayant autodéclaré des antécédents d'hypertension. Conclusions: Dans cette cohorte d'adultes du Québec avec un syndrome métabolique, l'utilisation de statines en monothérapie dans la prévention des maladies cardiovasculaires était associée à une alimentation dont la qualité était légèrement plus faible. Ces données suggèrent une complémentarité sous-optimale entre la qualité de l'alimentation et l'utilisation d'hypocholestérolémiants en prévention des maladies cardiovasculaires chez les personnes avec un syndrome métabolique.

Relationship Between Diet Quality and Glucose-Lowering Medication Intensity Among Adults With Type 2 Diabetes: Results From the CARTaGENE Cohort.

Background: In real-world settings, whether diet and medication are used as complements for glycemic management in type 2 diabetes (T2D) remains unclear. This study assessed the relationship between diet quality and intensity of glucose-lowering medication among adults with T2D. Methods: This cross-sectional study included 352 adults with T2D from the CARTaGENE Québec population-based cohort. Diet quality was assessed using the Healthful Plant-Based Diet Index (hPDI). Glucose-lowering medication intensity was graded according to self-reported information on the type and number of drugs: no medication; oral monotherapy; oral polytherapy; and insulin with and without oral medication. In the subsample of 239 individuals who reported the medication dosages, intensity was also graded using the Medication Effect Score (MES). Results: In multivariable-adjusted models, we found no evidence of a relationship between the hPDI and medication intensity, assessed using the categorical approach (Pbetween-group = 0.25) or the MES (P = 0.43). However, the hPDI was inversely associated with the MES among men < 50 years of age and women < 60 years (ß1-point MES = -2.24 [95% confidence interval, -4.46, -0.02] hPDI points), but not among older individuals (ß = -0.03 [-1.28, 1.21] hPDI points). Evidence of a nonsignificant inverse relationship between the hPDI and HbA1c was observed (ß10-point hPDI = -0.23% [-0.63, 0.17]), whereas a positive and significant association between the MES and hemoglobin (Hb)A1c was found (ß1-point MES = 0.30% [0.10, 0.51]). Conclusions: In this cohort of adults with T2D, there was an overall lack of complementarity between diet quality and intensity of glucose-lowering medication. The issue was particularly important among younger adults for whom diet quality was inversely associated with intensity of medication.

Introduction: Il n'a jamais été étudié, en contexte réel, si la qualité de l'alimentation et la médication sont utilisées de façon complémentaire dans la gestion de la glycémie chez des personnes avec le diabète de type 2 (DT2). La présente a évalué la relation entre la qualité de l'alimentation et l'intensité de la médication hypoglycémiante chez des adultes avec DT2. Méthodes: Cette étude transversale portait sur 352 adultes avec DT2 participant à la cohorte populationnelle québécoise CARTaGENE. Nous avons évalué la qualité du régime à l'aide du Healthful Plant-based Diet Index (hPDI, soit l'indice d'un régime alimentaire à base de plantes). Nous avons évalué l'intensité des médicaments hypoglycémiants à partir des renseignements fournis sur le type et le nombre de médicaments : aucun médicament, monothérapie orale, polythérapie orale, insuline avec ou sans médicaments par voie orale. Dans le sous-échantillon de 239 individus qui ont mentionné les posologies de médicaments, nous avons aussi évalué l'intensité au moyen du Medication Effect Score (MES). Résultats: Dans les modèles multivariés, nous n'avons observé aucune évidence de relation entre le hPDI et l'intensité des médicaments au moyen de l'approche catégorielle (Pentre les groupes = 0,25) ou du MES (P = 0,43). Toutefois, le hPDI était inversement associé au MES chez les hommes < 50 ans et chez les femmes < 60 ans (ßMES 1 point = ­2,24 [intervalle de confiance à 95 %, ­4,46, ­0,02] points hPDI), mais non chez les personnes plus âgées (ß = ­0,03 [­1,28, 1,21] point hPDI). Nous avons observé une relation inverse non significative entre le hPDI et l'hémoglobine (Hb)A1c (ßhPDI 10 points = ­0,23 % [­0,63, 0,17]) et une association positive et significative entre le MES et l'HbA1c (ßMES 1 point = 0,30 % [0,10, 0,51]). Conclusions: Au sein de cette cohorte d'adultes avec DT2, nous avons constaté une absence globale de complémentarité entre la qualité de l'alimentation et l'intensité des médicaments hypoglycémiants. Cet enjeu était d'autant plus important chez les personnes plus jeunes pour lesquels la qualité du régime était inversement associée à l'intensité des médicaments.

Relationship Between Diet Quality and Antihypertensive Medication Intensity Among Adults With Metabolic Syndrome-Associated High Blood Pressure.

Background: Management of high blood pressure (BP), a key feature of the metabolic syndrome (MetS), relies on diet and medication. Whether these modalities are used as complements has never been evaluated in real-world settings. This study assessed the relationship between diet quality and antihypertensive medication intensity among adults with MetS-associated high BP. Methods: This cross-sectional study included 915 adults with MetS-associated high BP from the CARTaGENE cohort (Québec, Canada), of whom 677 reported using BP-lowering medication. Antihypertensive medication intensity was graded per the number of BP-lowering classes used simultaneously. Diet quality was assessed using the Dietary Approach to Stop Hypertension (DASH) score. Results: No evidence of a relationship between antihypertensive medication intensity and diet quality was found (ß for each additional antihypertensive = -0.05; 95% CI, -0.35; 0.26 DASH score points). However, among men aged < 50 years and women aged < 60 years, the DASH score was inversely associated with medication intensity (ß = -0.72; 95% CI, -1.24, -0.19), whereas this relationship tended to be positive among older participants (ß = 0.32; 95% CI, -0.05, 0.69). Among participants with low Framingham risk score, the DASH score was inversely associated with medication intensity (ß = -0.70; 95% CI, -1.31, -0.09), but no evidence of an association was found among individuals at moderate (ß = 0.00; 95% CI, -0.45, 0.45) or high (ß = 0.30, 95% CI, -0.24, 0.84) risk. Conclusions: In this cohort of adults with MetS-associated high BP, there was an overall lack of complementarity between diet quality and BP-lowering medication, especially among younger individuals and those with a lower risk for cardiovascular disease for whom diet quality was inversely associated with intensity of medication.

Introduction: La prise en charge de la pression artérielle (PA) élevée, l'une des caractéristiques principales du syndrome métabolique (SMet), repose sur une saine alimentation et l'usage de médicaments hypotenseurs. Il n'a jamais été évalué si ces modalités étaient utilisées de façon complémentaire en contexte réel. La présente étude portait sur la relation entre la qualité de l'alimentation et la médication antihypertensive au sein d'adultes ayant une PA élevée associée au SMet. Méthodes: Cette étude transversale regroupait 915 adultes de la cohorte CARTaGENE (Québec, Canada) ayant une PA élevée associée au SMet, dont 677 ont rapporté prendre des médicaments abaissant la PA. L'intensité de la médication antihypertensive a été évaluée par le nombre de classes de médicaments abaissant la PA utilisées simultanément. La qualité du régime alimentaire a été évaluée à l'aide du score Dietary Approache to Stop Hypertension (DASH). Résultats: Aucune évidence d'une relation entre l'intensité des médicaments antihypertenseurs et la qualité de l'alimentation n'a été observée (ß pour chaque antihypertenseur supplémentaire = ­0,05 ; intervalle de confiance [IC] à 95 %, ­0,35 ; 0,26 point au score DASH). Toutefois, chez les hommes âgés < 50 ans et chez les femmes âgées < 60 ans, le score DASH était inversement associé à l'intensité des médicaments (ß = ­0,72 ; IC à 95 %, ­1,24, ­0,19), alors que cette relation avait tendance à être positive chez les participants plus âgés (ß = 0,32 ; IC à 95 %, ­0,05, 0,69). Chez les participants qui avaient un score de risque de Framingham faible, le score DASH était inversement associé à l'intensité des médicaments (ß = ­0,70 ; IC à 95 %, ­1,31, ­0,09), mais aucune évidence d'une association n'a été observée chez les individus qui avaient un risque modéré (ß = 0,00 ; IC à 95 %, ­0,45, 0,45) ou élevé (ß = 0,30, IC à 95 %, ­0,24, 0,84). Conclusions: Au sein de cette cohorte d'adultes qui avaient une PA élevée associée au SMet, aucune évidence de complémentarité entre la qualité de l'alimentation et l'intensité de la médication antihypertensive n'a été observée, particulièrement chez les individus plus jeunes et chez ceux exposés à un risque plus faible de maladies cardiovasculaires pour qui la qualité du régime alimentaire était inversement associée à l'intensité des médicaments.

Sugar-sweetened or artificially-sweetened beverage consumption, physical activity, and risk of cardiovascular disease in adults: a prospective cohort study.

BACKGROUND: Whether physical activity could mitigate the adverse impacts of sugar-sweetened beverages (SSBs) or artificially sweetened beverages (ASBs) on incident cardiovascular disease (CVD) remains uncertain. OBJECTIVES: This study aimed to examine the independent and joint associations between SSB or ASB consumption and physical activity and risk of CVD, defined as fatal and nonfatal coronary artery disease and stroke, in adults from 2 United States-based prospective cohort studies. METHODS: Cox proportional hazards models were used to calculate hazard ratios (HRs) and 95% CIs between SSB or ASB intake and physical activity with incident CVD among 65,730 females in the Nurses' Health Study (1980-2016) and 39,418 males in the Health Professional's Follow-up Study (1986-2016), who were free from chronic diseases at baseline. SSBs and ASBs were assessed every 4-y and physical activity biannually. RESULTS: A total of 13,269 CVD events were ascertained during 3,001,213 person-years of follow-up. Compared with those who never/rarely consumed SSBs or ASBs, the HR for CVD for participants consuming ≥2 servings/d was 1.21 (95% CI: 1.12, 1.32; P-trend < 0.001) for SSBs and 1.03 (95% CI: 0.97, 1.09; P-trend = 0.06) for those consuming ≥2 servings/d of ASBs. The HR for CVD per 1 serving increment of SSB per day was 1.18 (95% CI: 1.10, 1.26) and 1.12 (95% CI: 1.04, 1.20) for participants meeting and not meeting physical activity guidelines (≥7.5 compared with <7.5 MET h/wk), respectively. Compared with participants who met physical activity guidelines and never/rarely consumed SSBs, the HR for CVD was 1.47 (95% CI: 1.37, 1.57) for participants not meeting physical activity guidelines and consuming ≥2 servings/wk of SSBs. No significant associations were observed for ASB when stratified by physical activity. CONCLUSIONS: Higher SSB intake was associated with CVD risk regardless of physical activity levels. These results support current recommendations to limit the intake of SSBs even for physically active individuals.

Cardiovascular disease prevention in heterozygous familial hypercholesterolemia: how important is a healthy diet in the era of long-lasting cholesterol-lowering drug therapies?

PURPOSE OF REVIEW: This review aims to provide an in-depth perspective on the importance of diet for cardiovascular disease (CVD) prevention in heterozygous familial hypercholesterolemia (HeFH). RECENT FINDINGS: Even though data on diet and CVD prevention in HeFH are limited, the currently available evidence supports its cholesterol-lowering effect and its favorable association with CVD risk on the long-term. However, qualitative evidence from individuals with HeFH suggests that there is a common perception that diet is useless compared to medication, and this misconception serves as a barrier to healthy eating. On the other hand, evidence also suggests that individuals with HeFH are at higher risk of eating disorders compared with unaffected individuals. Family history of premature death and the chronic nature of the disease would be in cause. SUMMARY: Emphasizing a healthy diet needs to remain at the foundation of CVD prevention in HeFH. Evidence are limited but supportive of the cholesterol-lowering and cardioprotective potential effects of diet. Engaging in conversations about healthy dieting with individuals in HeFH is likely to help prevent misconceptions about diet. Additionally, it could help reduce the risk of eating disorders, which, altogether, is likely to improve overall CVD prevention.

Red meat intake and risk of type 2 diabetes in a prospective cohort study of United States females and males.

BACKGROUND: Studies with methodological advancements are warranted to confirm the relation of red meat consumption to the incidence of type 2 diabetes (T2D). OBJECTIVE: We aimed to assess the relationships of intakes of total, processed, and unprocessed red meat to risk of T2D and to estimate the effects of substituting different protein sources for red meats on T2D risk. METHODS: Our study included 216,695 participants (81% females) from the Nurses' Health Study (NHS), NHS II, and Health Professionals Follow-up Study (HPFS). Red meat intakes were assessed with semiquantitative food frequency questionnaires (FFQs) every 2 to 4 y since the study baselines. We used multivariable-adjusted proportional hazards models to estimate the associations between red meats and T2D. RESULTS: Over 5,483,981 person-years of follow-up, we documented 22,761 T2D cases. Intakes of total, processed, and unprocessed red meat were positively and approximately linearly associated with higher risks of T2D. Comparing the highest to the lowest quintiles, hazard ratios (HR) were 1.62 (95% confidence interval [CI]: 1.53, 1.71) for total red meat, 1.51 (95% CI: 1.44, 1.58) for processed red meat, and 1.40 (95% CI: 1.33, 1.47) for unprocessed red meat. The percentage lower risk of T2D associated with substituting 1 serving/d of nuts and legumes for total red meat was 30% (HR = 0.70, 95% CI: 0.66, 0.74), for processed red meat was 41% (HR = 0.59, 95% CI: 0.55, 0.64), and for unprocessed red meat was 29% (HR = 0.71, 95% CI: 0.67, 0.75); Substituting 1 serving/d of dairy for total, processed, or unprocessed red meat was also associated with significantly lower risk of T2D. The observed associations became stronger after we calibrated dietary intakes to intakes assessed by weighed diet records. CONCLUSIONS: Our study supports current dietary recommendations for limiting consumption of red meat intake and emphasizes the importance of different alternative sources of protein for T2D prevention.

The Longevity Protein Klotho: A Promising Tool to Monitor Lifestyle Improvements.

Aging is not a disease; it is a natural evolution of human physiology. Medical advances have extended our life expectancy, but chronic diseases and geriatric syndrome continue to affect the increasingly aging population. Yet modern medicine perpetuates an approach based on treatment rather than prevention and education. In order to help solve this ever-growing problem, a new discipline has emerged: lifestyle medicine. Nutrition, physical activity, stress management, restorative sleep, social connection, and avoidance of risky substances are the pillars on which lifestyle medicine is founded. The aim of this discipline is to increase healthspan and reduce the duration of morbidity by making changes to our lifestyle. In this review, we propose the use of klotho protein as a novel biomarker for lifestyle medicine in order to quantify and monitor the health status of individuals, as no integrative tool currently exists.

Relationship between lifestyle habits and cardiovascular risk factors in familial hypercholesterolemia.

BACKGROUND AND AIM: Little is known about the cardioprotective potential of a healthy lifestyle in familial hypercholesterolemia (FH). The objective of this study was to evaluate the relationship between lifestyle and cardiovascular risk factors in adults with FH. METHODS AND RESULTS: This cross-sectional study leveraged data from the CARTaGENE Quebec population-based cohort (Canada). Participants with FH were identified using the validated Simplified Canadian Definition for FH. A healthy lifestyle score (HLS), ranging from 0 to 5, was calculated per adherence to 5 lifestyle habits: 1) not smoking; 2) being physically active (≥150 min/week of moderate or vigorous physical activity); 3) eating a healthy diet (Alternate Healthy Eating Index ≥50%); 4) having a light to moderate alcohol consumption (men: 1-30 g/day; women: 1-15 g/day); and 5) sleeping 7-8 h/day. Among the 122 included individuals (women, n = 78; men, n = 44; mean age ± SD: 57.3 ± 6.7 years), 92 (75.4%) had a HLS ≤3/5, while only 5 (4.1%) had a HLS of 5/5. After adjustments for sex, age, body mass index, and lipid-lowering medication use, we found no evidence of an association between the HLS and concentrations of LDL-cholesterol (ß = 0.04, 95% CI = -0.08, 0.15 mmol/L; P = 0.54). However, the HLS was favorably associated with HbA1c levels (ß = -0.07, 95% CI = -0.13, -0.01%; P = 0.02), and statistical trends suggested favorable associations with HDL-cholesterol (ß = 0.06, 95% CI = -0.02, 0.14 mmol/L; P = 0.06) and waist circumference (ß = -2.22, 95% CI = -4.62, 0.17 cm; P = 0.07). CONCLUSION: This study suggests that a healthy lifestyle is favorably associated with CVD risk factors in adults with FH.

Methyl Donor Nutrient Intake and Incidence of Type 2 Diabetes: Results From Three Large U.S. Cohorts.

OBJECTIVE: We examined whether intake of methyl donor nutrients, including vitamins B2, B6, and B12 and folate, from foods and/or supplements is associated with type 2 diabetes risk. RESEARCH DESIGN AND METHODS: We included 203,644 women and men from the Nurses' Health Study (1984-2016), Nurses' Health Study 2 (1991-2017), and Health Professionals Follow-Up Study (1986-2016). Dietary data were collected every 2-4 years with use of semiquantitative food-frequency questionnaires. Cox proportional hazards models with time-varying covariates were used to evaluate associations between each nutrient and type 2 diabetes risk. We combined cohort-specific hazard ratios (HRs) using inverse variance-weighted fixed-effects meta-analyses. RESULTS: During 4,900,181 person-years of follow-up, we documented 19,475 incident type 2 diabetes cases. In multivariable-adjusted meta-analyses, participants in the highest quintiles of total vitamin B2 and B6 intakes had lower risk of diabetes compared with those in the lowest quintiles (HR 0.93 [95% CI 0.89, 0.98] for B2 and 0.93 [0.89, 0.97] for B6). With stratification by source, significant associations remained for B2 from food but not from supplements. Neither association for B6 from food nor association for B6 from supplements attained significance. No association was observed between total B12 intake and diabetes. However, B12 from food was marginally associated with higher diabetes risk (1.05 [1.00-1.11]) but not after additional adjustment for red meat intake (1.04 [0.99-1.10]). No evidence of association was observed between intakes of folate and diabetes. CONCLUSIONS: The results of our study suggest that higher intake of vitamin B2 and B6, especially B2 from food sources, may be associated with a modestly lower type 2 diabetes risk.

Sugar- or artificially-sweetened beverage consumption, physical activity, and risk of cardiovascular disease in US adults.

Background: The extent to which physical activity attenuates the detrimental effects of sugar (SSBs)- or artificially-sweetened beverages (ASBs) on the risk of cardiovascular disease is unknown. Methods: We used Cox proportional-hazards models to calculate hazard ratios and 95% confidence interval [HR (CI)] between SSB or ASB intake and physical activity with cardiovascular disease risk among 65,730 women in the Nurses' Health Study (1980-2016) and 39,418 men in the Health Professional's Follow-up Study (1986-2016), who were free from chronic diseases at baseline. SSBs and ASBs were assessed every 4-years and physical activity biannually. Results: A total of 13,269 cardiovascular events were ascertained during 3,001,213 person-years of follow-up. Compared with those that never/rarely consumed SSBs or ASBs, HR and 95% CI for cardiovascular disease for participants consuming ≥2 servings/day were 1.21 (95% CI,1.12 to 1.32; P-trend<0.001) and 1.03 (95% CI, 0.97 to 1.09; P-trend=0.06), respectively. In the joint analyses, for participants meeting and not meeting physical activity guidelines (<7.5 vs ≥7.5 MET-h/week) as well as consuming ≥2 servings/day of SSBs or ASBs, the HRs for cardiovascular disease were 1.15 (95% CI, 1.08 to 1.23) and 0.96 (95% CI, 0.91 to 1.02), and 1.47 (95% CI, 1.37 to 1.57) and 1.29 (95% CI, 1.22 to 1.37) respectively, compared with participants who met physical activity guidelines and never/rarely consumed these beverages. Similar patterns were observed when coronary heart disease and stroke were analyzed. Conclusions: Our findings suggest that among physically active participants, higher SSB intake, but not ASBs, is associated with a higher cardiovascular risk. Our results support current recommendations to limit the intake of SSB and maintain adequate physical activity levels.

Are Lipid-Lowering and Antihypertensive Medications Used as Complements to Heart-Healthy Diets? A Scoping Review.

In cardiovascular disease (CVD) prevention, whether antihypertensive and lipid-lowering medications are used as complements to heart-healthy diets has not been thoroughly assessed. This scoping review aimed to 1) analyze observational studies that assessed the relationship between diet and antihypertensive/lipid-lowering medication use and 2) evaluate whether medication was used as a complement to heart-healthy dietary intakes. We searched MEDLINE, Embase, Web of Science, and CINAHL through 14 January, 2023, for studies that assessed either 1) intraindividual changes in diet associated with lipid-lowering/antihypertensive medication initiation or use or 2) interindividual differences in diet between users and nonusers of these medications. A total of 17 studies were included. Of those, 3 prospectively assessed the intraindividual changes in diet associated with medication initiation or use, but none documented potential changes in diet prior to medication initiation. The 14 other studies compared dietary intakes of medication users and nonusers, most of which also relied on an incomplete assessment of the temporal dynamics between diet and medication use as they employed cross-sectional (n = 12) or repeated cross-sectional (n = 2) designs. Data from 8 studies, including 4 of the 5 studies from Europe, suggested that medication was used as a complement to heart-healthy diets, whereas data from the 9 other studies, including the 4 conducted in the United States, provided no such evidence, indicating potential between-country differences in this relationship. Finally, no studies investigated how the dynamics between diet and medication use influenced the long-term CVD risk. This scoping review suggests that the current literature on the relationship between lipid-lowering/antihypertensive medication use and diet provides an incomplete perspective on how medication may influence diet in CVD prevention. Prospective studies assessing intraindividual changes in diet associated with medication initiation and use and how these dynamics influence the CVD risk are thus needed.

Intakes of Unprocessed and Minimally Processed and Ultraprocessed Food Are Associated with Diet Quality in Female and Male Health Professionals in the United States: A Prospective Analysis.

BACKGROUND: High unprocessed and minimally processed food (UMP) intake has been associated with high-quality diets, whereas the opposite has been shown for ultraprocessed food (UPF). Nevertheless, the association between UMP and UPF consumption and diet quality over the long-term warrants further examination. OBJECTIVE: This study aimed to assess whether UMP and UPF intake are associated with three diet-quality metrics in female and male health professionals from two US cohorts over 3 decades of follow-up. DESIGN: This was a cohort study, including data from the Nurses' Health Study (NHS), from 1986 to 2010 (N = 51,956) and the Health Professionals Follow-up Study (HPFS) from 1986 to 2006 (n = 31,307). PARTICIPANTS AND SETTING: Participants were invited in 1976 (NHS) and 1986 (HPFS) to respond to mailed questionnaires every 2 to 4 years and diet was assessed with a semi-quantitative food frequency questionnaire every 4 years. MAIN EXPOSURE MEASURES: UMP and UPF intake were calculated using the NOVA classification. STATISTICAL ANALYSES: Generalized estimating equations for marginal means and repeated cross-sectional associations between diet-quality metrics and quintiles of UMP and UPF. Diets were assessed every 4 years from 1986 to 2010. RESULTS: With increasing quintiles of UMP intakes, the Alternate Healthy Eating Index-2010 increased 7.1% (3.80 points, 95% CI 3.66 to 3.93) in the NHS and 10.1% (5.75 points, 95% CI 5.52 to 5.98) in the HPFS; the Mediterranean diet index increased 11.7% (0.50 points, 95% CI 0.47 to 0.52) in the NHS and 14.0% (0.64 points, 95% CI 0.60 to 0.68) in the HPFS; and the Dietary Approaches To Stop Hypertension diet score increased 7.5% (1.81 points, 95% CI 1.76 to 1.87) in the NHS and 10.6% (2.66 points, 95% CI 2.57 to 2.76) in the HPFS. In the fifth quintile of UPF intake compared with the first, the Alternate Healthy Eating Index-2010 was -9.3% (-4.60 points, 95% CI -4.73 to -4.47) lower in the NHS and -13.7% (-6.89 points, 95% CI -7.12 to -6.66) lower in the HPFS; the Mediterranean diet index was -14.7% (-0.55 points, 95% CI -0.57 to -0.53) lower in the NHS, and -19.0% (-0.74 points, 95% CI -0.78 to -0.70) lower in the HPFS; and the Dietary Approaches To Stop Hypertension diet score was -8.1% (-1.81 points, 95% CI -1.86 to -1.76) lower in the NHS and -12.8% (-2.84 points, 95% CI -2.93 to -2.74) lower in the HPFS. CONCLUSIONS: Consumption of UMP was associated with better dietary quality, whereas consumption of UPF was associated with poorer dietary quality.

Household Food Insecurity and Changes in BMI Z-Score in a Pediatric Obesity Management Clinic.

BACKGROUND: Multicomponent lifestyle interventions are fundamental in pediatric obesity management. However, whether household food insecurity influences the efficacy of such interventions remains undocumented. OBJECTIVES: The objective was to compare changes in BMI z-score (BMIz) among children whose family received lifestyle counseling at a pediatric obesity management clinic in Montréal (Canada) according to their household food security status. METHODS: This is a retrospective, longitudinal analysis of medical records of children (2-17 y) with overweight or obesity who received lifestyle counseling at a pediatric obesity management clinic. The number of visits at the clinic and the duration of the follow-up were individualized. Household food security status was assessed using the Health Canada's Household Food Security Survey Module at the first visit at the clinic. BMIz was calculated and updated at each visit. A reduction of ≥0.25 in BMIz between the last and the first visit at the clinic was considered clinically meaningful. Statistical significance was considered at P < 0.05. RESULTS: Among the 214 children included in the study, 83 (38.8%) lived in a food insecure household. In multivariable-adjusted analyses, differences in BMIz between the last and the first appointment tended to be smaller among children who lived in a food insecure household than those in children living in a food secure household [ΔBMIzfood insecurity = -0.432 (95% CI: -0.672, -0.193) compared with ΔBMIzfood security = -0.556 (95% CI: -0.792, -0.319; P = 0.14)]. Differences were most notable in the first 6 mo of follow-up. The OR of achieving a clinically significant reduction in BMIz over follow-up associated with household food insecurity, compared with household food security, was 0.57 (95% CI: 0.31, 1.05; P = 0.07). CONCLUSIONS: In this sample of children followed up at a pediatric obesity clinic, those who lived in a food insecure household experienced smaller BMIz reductions than those who lived in a food secure household.
