Clinical Characteristics and Treatment Efficacy for Co-Morbid Insomnia and Sleep Apnea (COMISA): Evidence from Qualitative and Quantitative Analysis

ABSTRACT Objectives A multitude of physical and mental challenges are being faced in the population with Co-morbid Insomnia and Sleep Apnea (COMISA). Unfortunately, research about clinical characteristics and management of COMISA based on quantitative evidence is lacking. Method Standard procedures for literature retrieval, selection and quality assessment, data extraction, analysis, and interpretation were conducted step by step. For studying the sleep characteristics, common complications and widely recognized treatment options for COMISA, Weighted Mean Difference (WMD) and Odds Ratio (OR) were applied to assess the mean and risk differences between compared groups. Outcomes included sleep health parameters and secondary impairments in physical and mental well-being. Results COMISA showed worse sleep quality than OSA only by PSQI (WMD = 3.38 point) and heavier sleep fragmentation (WMD = 11.46 min) than insomnia only. Besides, COMISA patients showed a higher risk for depression (OR [95%CI] = 5.03[2.31, 10.93]) and PTSD (OR [95%CI] = 3.96[1.85, 8.46]) in comparison with OSA alone. Compared to insomnia alone, COMISA patients suffered from more than two times higher risk of cardiovascular diseases, hypertension, and diabetes. In treating COMISA patients, combining CBTI with PAP treatment can enhance the improvement of insomnia severity (ISI, WMD [95%CI] =-3.26[−4.51, −2.00] point) and sleep efficiency (WMD [95%CI] = 6.39[1.97, 10.81] %) compared to PAP alone. Conclusions Impaired sleep domains in COMISA cover sleep quality and sleep structure. Also, COMISA has a higher risk for cardiometabolic diseases and mental disorders. Combining CBTI with PAP can be a recommended treatment to relieve sleep impairments for COMISA.

Abstract P527: Acculturation and Family History Are Associated With Sleep Disturbances in US Americans of South Asian Origin

Introduction: Sleep disorders are an important risk for cardiovascular disease. Although the effects of sleep-disordered breathing have been widely studied in general populations, there is a gap in understanding its prevalence and determinants among South Asians in the United States of America (US), a group with high risk of cardiometabolic disease that presents unique genetic burdens and acculturation issues. We examined the association of family history of sleep disturbances and acculturation in a survey of South Asian immigrants. Methods: We surveyed 105 US South Asian participants (20-75 years, 69% male, 92% born in South Asia) recruited at a community event. Respondents provided information on age, gender, acculturation (measured by the adoption of English spoken at home), and family history of severe snoring in first degree relatives. We used a modified Berlin Sleep Questionnaire, where the obesity criterion was replaced with current diabetes to identify persons with high-risk sleep disturbances and asked about severe snoring in first degree relatives to identify family history of sleep disturbances. We examined the association of high-risk sleep disturbances with family history and acculturation metrics using Chi-squared tests, followed by logistic regression analysis. Results: Of the 105 participants, 28 (26.7%) were identified as high-risk for sleep disturbances. Those at high risk had a median age of 61 years, significantly older than their low-risk counterparts (median age 53; p=0.015). Of the 55% individuals who were acculturated to now speak English at home, 34% had high risk sleep disturbances as compared to 17% with sleep disturbances among those that continued to speak their native non-English language (p=0.044). Of the 10% individuals whose siblings had severe snoring problems, 50% had high risk sleep disturbances vs. 24% in those without sibling history (p = 0.079). In logistic regression models adjusting for age and gender, both sibling history (Odds Ratio 4.6, 95% CI 1.0 to 20.3, p = 0.047) and acculturation (Odds Ratio 3.0, 95% CI 1.1 to 8.6, p = 0.037) were associated with high-risk sleep disturbances. Conclusions: Acculturation as measured by adoption of English as the home language and family history of severe snoring are both associated with sleep disturbances among US South Asians in. Healthcare providers should be especially vigilant for sleep disorders in acculturated South Asian patients and those with such family and social history. Further studies are needed to understand the relationships between genetic predispositions, acculturation, and environmental factors in this population.

Generation of induced pluripotent stem cell lines from South Asian ethnicity

South Asians, which represent around 25% of the world’s population, have a disproportionately high risk of cardiometabolic disease, two-fold higher risk of myocardial infarction, and 4- to 6-fold higher risk for diabetes compared to Caucasians. We generated two induced pluripotent stem cell (iPSC) lines from healthy South Asian donors and validated the pluripotency and ability of these cell lines to differentiate into three germ layers. These iPSC lines can be applied to generate many cardiovascular cell types such as cardiomyocytes, endothelial cells, and mural cells to investigate different cardiovascular disease mechanisms triggered by environmental risk factors or drugs in vitro.

Applications of Mobile Health Technologies to Address Cardiometabolic Health Disparities in the United States: A Systematic Review

Introduction Black and Hispanic adults are disproportionately burdened by cardiometabolic disorders. The aim of this systematic review was to examine the effectiveness of mobile health technologies to promote disease prevention and self-management among US adults in diverse communities. Methods Potential studies were identified using a comprehensive search of the PubMed and EMBASE databases for recent studies published from December 2018 through 2021. Keywords and search strategies were established to focus on health disparity populations and the application of mobile health technology for cardiovascular disease risk reduction. Titles and abstracts were assessed and, if a study was eligible, 2 independent reviewers completed a full-length review with extraction in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results A total of 13 studies met our inclusion criteria. Study sample sizes ranged from 8 to 533 baseline participants. Studies were conducted in diverse communities (eg, North Carolina and California). Most studies used mobile applications (n=11) and a majority used accelerometers or similar technologies (eg, smartwatches) to assess changes in dietary behavior, blood pressure control, and physical activity. Overall, studies reported positive associations between mobile technology use and risk factor reduction actions and behaviors. Long-term adherence varied across studies. Those that prioritized culturally tailored approaches reported more significant impacts than those that did not. Conclusions Evidence suggests that mobile technology may be useful in promoting disease self-management and risk reduction among populations at higher risk of cardiometabolic diseases. The use of mobile health technologies, particularly when tailored to target populations, may be a practical approach to advancing population health equity.

Fatty Liver Index (FLI) Identifies Not Only Individuals with Liver Steatosis but Also at High Cardiometabolic Risk.

A fatty liver index (FLI) greater than sixty (FLI ≥ 60) is an established score for metabolic dysfunction-associated steatotic liver disease (MASLD), which carries a high risk for diabetes and cardiovascular disease, while a FLI ≤ 20 rules out the presence of steatosis. Thus, we investigated whether FLI was associated with cardiometabolic risk factors, i.e., visceral (VAT), subcutaneous (SC), epicardial (EPI), extrapericardial (PERI), and total cardiac (CARD-AT) adipose tissue, hepatic fat ((by magnetic resonance imaging, MRI, and spectroscopy, MRS), and insulin resistance (IR, HOMA-IR and OGIS-index), and components of metabolic syndrome. All individuals with FLI ≥ 60 had MASLD, while none with FLI ≤ 20 had steatosis (by MRS). Subjects with FLI ≥ 60 had a higher BMI and visceral and cardiac fat (VAT > 1.7 kg, CARD-AT > 0.2 kg). FLI was positively associated with increased cardiac and visceral fat and components of metabolic syndrome. FLI, VAT, and CARD-AT were all associated with IR, increased blood pressure, cholesterol, and reduced HDL. For FLI ≥ 60, the cut-off values for fat depots and laboratory measures were estimated. In conclusion, FLI ≥ 60 identified not only subjects with steatosis but also those with IR, abdominal and cardiac fat accumulation, increased blood pressure, and hyperlipidemia, i.e., those at higher risk of cardiometabolic diseases. Targeted reduction of FLI components would help reduce cardiometabolic risk.

Birth weight influences cardiac structure, function, and disease risk: evidence of a causal association.

Low birth weight is a common pregnancy complication, which has been associated with higher risk of cardiometabolic disease in later life. Prior Mendelian randomization (MR) studies exploring this question do not distinguish the mechanistic contributions of variants that directly influence birth weight through the foetal genome (direct foetal effects), vs. variants influencing birth weight indirectly by causing an adverse intrauterine environment (indirect maternal effects). In this study, MR was used to assess whether birth weight, independent of intrauterine influences, is associated with cardiovascular disease risk and measures of adverse cardiac structure and function. Uncorrelated (r2 < .001), genome-wide significant (P < 5 × 10-8) single nucleotide polymorphisms were extracted from genome-wide association studies summary statistics for birth weight overall, and after isolating direct foetal effects only. Inverse-variance weighted MR was utilized for analyses on outcomes of atrial fibrillation, coronary artery disease, heart failure, ischaemic stroke, and 16 measures of cardiac structure and function. Multiple comparisons were accounted for by Benjamini-Hochberg correction. Lower genetically-predicted birth weight, isolating direct foetal effects only, was associated with an increased risk of coronary artery disease (odds ratio 1.21, 95% confidence interval 1.06-1.37; P = .031), smaller chamber volumes, and lower stroke volume, but higher contractility. The results of this study support a causal role of low birth weight in cardiovascular disease, even after accounting for the influence of the intrauterine environment. This suggests that individuals with a low birth weight may benefit from early targeted cardiovascular disease prevention strategies, independent of whether this was linked to an adverse intrauterine environment during gestation.

Genetic architecture of DCC and influence on psychological, psychiatric and cardiometabolic traits in multiple ancestry groups in UK Biobank

BackgroundPeople with severe mental illness have a higher risk of cardiometabolic disease than the general population. Traditionally attributed to sociodemographic, behavioural factors and medication effects, recent genetic studies have provided evidence of shared biological mechanisms underlying mental illness and cardiometabolic disease. We aimed to determine whether signals in the DCC locus, implicated in psychiatric and cardiometabolic traits, were shared or distinct. MethodsIn UK Biobank, we systematically assessed genetic variation in the DCC locus for association with metabolic, cardiovascular and psychiatric-related traits in unrelated “white British” participants (N = 402,837). Logistic or linear regression were applied assuming an additive genetic model and adjusting for age, sex, genotyping chip and population structure. Bonferroni correction for the number of independent variants was applied. Conditional analyses (including lead variants as covariates) and trans-ancestry analyses were used to investigate linkage disequilibrium between signals. ResultsSignificant associations were observed between DCC variants and smoking, anhedonia, body mass index (BMI), neuroticism and mood instability. Conditional analyses and linkage disequilibrium structure suggested signals for smoking and BMI were distinct from each other and the mood traits, whilst individual mood traits were inter-related in a complex manner. LimitationsRestricting analyses in non-“white British” individuals to the phenotypes significant in the “white British” sample is not ideal, but the smaller samples sizes restricted the phenotypes possible to analyse. ConclusionsGenetic variation in the DCC locus had distinct effects on BMI, smoking and mood traits, and therefore is unlikely to contribute to shared mechanisms underpinning mental and cardiometabolic traits.

Echocardiography protocol and cardiometabolic phenotyping in Indian birth cohorts-the IndEcho study.

Asian Indians are at higher risk of cardiometabolic disease compared to other ethnic groups, and the age of onset is typically younger. Cardiac structure and function are poorly characterized in this ethnic group. In this study, we describe image-acquisition methods and the reproducibility of measurements and detailed echocardiography characteristics in two large Indian population-based cohorts (the New Delhi and Vellore Birth Cohorts) from India. The IndEcho study captured transthoracic echocardiographic measurements of cardiac structure and function from 2,322 men and women aged 43-50 years. M-mode measurements in the parasternal long axis (PLAX) and 2-dimensional (2D) short axis recordings at the mitral valve, mid-papillary and apical level were recorded. Apical 2D recordings of two- three- and four-chamber (2C, 3C and 4C) views and Doppler images (colour, pulsed and continuous) were recorded in cine-loop format. Left ventricular (LV) mass, LV hypertrophy, and indices of LV systolic and diastolic function were derived. Echocardiographic measurements showed good/excellent technical reproducibility. Hetero-geneity across sites, sex and rural/urban differences in cardiac structure and function were observed. Overall, this cohort of South Asian Indians had smaller LV mass and normal systolic and diastolic function when compared with published data on other Asian Indians and the West, (LV mass indexed for body surface area: Delhi men: 68 g/m2, women 63.9; Vellore men: 65.8, women 61.6) but were within ethnic-specific reference ranges. The higher prevalence of obesity, diabetes and hypertension is reflected by the higher proportion of LV remodelling and lesser hypertrophy. Our study adds to scarce population-based echocardiographic data for mid-life Asian Indians. Compared to published literature on other ethnic groups, the Asian Indian heart is characterised by smaller cardiac dimensions and normal range systolic and diastolic function on a background of a high prevalence of hypertension, diabetes and cardiac disease at a relatively young age. This data will form the basis for further analyses of lifecourse, metabolic and body composition predictors of cardiac structure and function, and echocardiographic predictors of future mortality. 13432279.

Cardiorespiratory Fitness and Leg Muscle Power in Relation to Abdominal Adipose Tissue in Adolescents

Background: Abdominal adiposity is associated with high risk of cardiometabolic diseases. Waist circumference has been used as a surrogate measure of abdominal adipose tissue in both youth and adults. Objectives: The present study evaluated whether cardiorespiratory fitness and leg power (LP) were independently associated with abdominal adipose tissue in 12-16-year-old Nigerian adolescents. Methods: This cross-sectional study comprised 2047 (1087 girls and 960 boys) adolescents who were evaluated for cardiorespiratory fitness and leg power. The cardiorespiratory fitness and leg power were assessed using the progressive cardiovascular endurance run (PACER) test and the vertical jump (VJ) test, respectively. Abdominal adiposity was evaluated with the waist circumference (WC). Regression models controlling for age and maturity status were used to assess the association of fitness and LP with WC. Results: Low leg power had significant negative association with the risk of abdominal adiposity in both girls (β=-0.307; p0.001) and boys (β=-0.262; p0.001). The observed relationship was independent of fitness, whereas the relationship between fitness and risk of abdominal adiposity was partly determined by leg power. Conclusion: Leg power and fitness were independently associated with the risk of abdominal adiposity in adolescents, but the association of leg power was stronger in girls. Health promotion efforts targeting reduction of abdominal adipose tissue should also include muscular power training type activities in addition to endurance-related activities.

Sex-Specific Associations of Red Meat and Processed Meat Consumption with Serum Metabolites in the UK Biobank.

Red meat consumption has been found to closely related to cardiometabolic health, with sex disparity. However, the specific metabolic factors corresponding to red meat consumption in men and women have not been examined previously. We analyzed the sex-specific associations of meat consumption, with 167 metabolites using multivariable regression, controlling for age, ethnicity, Townsend deprivation index, education, physical activity, smoking, and drinking status among ~79,644 UK Biobank participants. We also compared the sex differences using an established formula. After accounting for multiple testing with false discovery rate < 5% and controlling for confounders, the positive associations of unprocessed red meat consumption with branched-chain amino acids and several lipoproteins, and the inverse association with glycine were stronger in women, while the positive associations with apolipoprotein A1, creatinine, and monounsaturated fatty acids were more obvious in men. For processed meat, the positive associations with branched-chain amino acids, several lipoproteins, tyrosine, lactate, glycoprotein acetyls and inverse associations with glutamine, and glycine were stronger in women than in men. The study suggests that meat consumption has sex-specific associations with several metabolites. This has important implication to provide dietary suggestions for individuals with or at high risk of cardiometabolic disease, with consideration of sex difference.

The Plasma Oxylipin Signature Provides a Deep Phenotyping of Metabolic Syndrome Complementary to the Clinical Criteria.

Metabolic syndrome (MetS) is a complex condition encompassing a constellation of cardiometabolic abnormalities. Oxylipins are a superfamily of lipid mediators regulating many cardiometabolic functions. Plasma oxylipin signature could provide a new clinical tool to enhance the phenotyping of MetS pathophysiology. A high-throughput validated mass spectrometry method, allowing for the quantitative profiling of over 130 oxylipins, was applied to identify and validate the oxylipin signature of MetS in two independent nested case/control studies involving 476 participants. We identified an oxylipin signature of MetS (coined OxyScore), including 23 oxylipins and having high performances in classification and replicability (cross-validated AUCROC of 89%, 95% CI: 85–93% and 78%, 95% CI: 72–85% in the Discovery and Replication studies, respectively). Correlation analysis and comparison with a classification model incorporating the MetS criteria showed that the oxylipin signature brings consistent and complementary information to the clinical criteria. Being linked with the regulation of various biological processes, the candidate oxylipins provide an integrative phenotyping of MetS regarding the activation and/or negative feedback regulation of crucial molecular pathways. This may help identify patients at higher risk of cardiometabolic diseases. The oxylipin signature of patients with metabolic syndrome enhances MetS phenotyping and may ultimately help to better stratify the risk of cardiometabolic diseases.

Potential reductions in ultra-processed food consumption substantially improve population cardiometabolic-related dietary nutrient profiles in eight countries

Background and aimsThe negative effect on dietary nutrient profiles is the most obvious mechanism explaining the higher risk of cardiometabolic diseases associated with increased dietary share of UPF observed in large cohort studies.We estimate the proportion of diets with excessive energy density, excessive free sugars or saturated fat contents and insufficient fiber that could be avoided, if UPF consumption was reduced to levels among lowest consumers across eight countries, as well as the proportion of diets with multiple inadequacies. Methods and resultsUsing nationally-representative cross-sectional surveys from Brazil (2008–09), Chile (2010), Colombia (2005), Mexico (2012), Australia (2011–12), the UK (2008–16), Canada (2015), and the US (2015–16), inadequate energy density (≥2.25 kcal/g) or contents of free sugars (>10% of total energy intake), saturated fats (>10% of total energy intake) and fiber (<25 g/2000 kcal) population attributable fractions were quantified.Substantial reductions in nutrient inadequacies would be observed ranging from 50.4% in Chile to 76.8% in US for dietary energy density, from 15.5% in Colombia to 68.4% in Australia for free sugars, from 9.5% in Canada to 35.0% in Mexico for saturated fats, and from 10.3% in UK to 37.9% in Mexico for fiber. Higher reductions would be observed for diets with multiple nutrient inadequacies: from 27.3% in UK to 77.7% in Australia for ≥3 and from 69.4% in Canada to 92.1% in US, for 4 inadequacies. ConclusionsLowering dietary contribution of UPF to levels among country-specific lowest consumers is a way to improve population cardiometabolic-related dietary nutrient profiles.

The gut microbiota-bile acid axis links the positive association between chronic insomnia and cardiometabolic diseases

Evidence from human cohorts indicates that chronic insomnia is associated with higher risk of cardiometabolic diseases (CMD), yet whether gut microbiota plays a role is unclear. Here, in a longitudinal cohort (n = 1809), we find that the gut microbiota-bile acid axis may link the positive association between chronic insomnia and CMD. Ruminococcaceae UCG-002 and Ruminococcaceae UCG-003 are the main genera mediating the positive association between chronic insomnia and CMD. These results are also observed in an independent cross-sectional cohort (n = 6122). The inverse associations between those gut microbial biomarkers and CMD are mediated by certain bile acids (isolithocholic acid, muro cholic acid and nor cholic acid). Habitual tea consumption is prospectively associated with the identified gut microbiota and bile acids in an opposite direction compared with chronic insomnia. Our work suggests that microbiota-bile acid axis may be a potential intervention target for reducing the impact of chronic insomnia on cardiometabolic health.

Differences in total and regional body fat and their association with BMI in UK-born White and South Asian children: findings from the Born in Bradford birth cohort.

Background: Body mass index (BMI) is commonly used as a proxy to determine excess adiposity, though this may underestimate fat mass (FM) in individuals of South Asian (SA) heritage. SA tend to have greater central adiposity than white people, which is associated with a higher risk of cardiometabolic disease. In this cross-sectional study, we aimed to determine the differences in total and regional FM using Dual-energy X-ray absorptiometry (DXA), and to see if any differences in FM varied by BMI category in UK-born white and SA children aged ~9 years. Methods: Anthropometric measurements and DXA scans were undertaken from 225 white and 269 SA children from the Born in Bradford cohort study. Linear regression was used to assess ethnic differences in total body fat percent and total and regional FM. Results: Although mean BMI was similar, compared to white children, the proportion of SA children who were overweight or obese was ~10% higher, and the proportion with > 35% total body fat (TBF) was 22% and 16% higher in boys and girls respectively. Mean TBF% was greater in SA children compared to white children in the same BMI category. Fat mass index (FMI) was higher in all body regions in SA children in all BMI categories; as was total and truncal FMI in healthy and overweight, but not obese, SA children. Conclusions: Greater TBF% and total and regional FM in SA children suggests they may be at greater risk of future cardiometabolic disease at a BMI level below the obesity threshold. However, our sample size was small, and results may be influenced by selection bias and confounding; our findings need to be replicated in a larger study.

IDF21-0617 Z-score of the log-transformed A Body Shape Index predicts low muscle mass in population with abdominal obesity

Background: Sarcopenic obesity is associated with a higher risk of cardiometabolic disease and mortality than either sarcopenia or obesity alone. However, no study has investigated body shape indices for the assessment of sarcopenia in obese populations.

Abdominal obesity and incident cardio-metabolic disorders in Asian-Indians: A 10-years prospective cohort study

Background and aimsTo estimate the strength of association between abdominal obesity and incident cardio-metabolic diseases. MethodsA subset of Chandigarh Urban Diabetes study cohort (n = 543) was followed after a mean of 10.7 years for development of diabetes, prediabetes, dysglycaemia (either prediabetes or diabetes), hypertension and atherosclerotic cardiovascular disease (ASCVD). Diabetes and prediabetes were defined as per American Diabetes Association consulting group criteria, hypertension as blood pressure of ≥140/90 mmHg and ASCVD after review of medical records. Abdominal obesity was defined as waist circumference of ≥80 cm and ≥90 cm in females and males, respectively. ResultsAs compared to non-obese (n = 209), abdominally obese individuals (n = 334) had a higher risk of diabetes [RR:1.82(1.28–2.57)], prediabetes [RR:1.40(1.05–1.85)], dysglycaemia [ RR:1.38(1.07–1.78)], hypertension [RR: 1.84(1.30–2.59)] and ASCVD [RR:2.12(1.02–4.4)]. The optimal cut-off of waist circumference for detecting incident diabetes, hypertension and ASCVD in females was 88 cm, 85 cm and 91 cm, respectively; while in males it was 90 cm, 87 cm and 94 cm, respectively. ConclusionIn Asian-Indians, abdominal obesity as defined by waist circumference of ≥90 cm and ≥80 cm in males and females, respectively is associated with a twofold higher risk of diabetes, hypertension and ASCVD. In addition, the current-cut-offs of waist circumference to define abdominal obesity need reconsideration to optimally identify individuals at a higher risk of cardio-metabolic diseases. However, a high attrition rate represents a major limitation.

Racial/ethnic minorities have greater declines in sleep duration with higher risk of cardiometabolic disease: An analysis of the U.S. National Health Interview Survey

ObjectiveHabitual insufficient sleep may contribute to cardiometabolic disease in the United States, particularly among racial and ethnic minorities. However, there is mixed evidence on secular trends in U.S. sleep duration. Study designCross-sectional data from 413,417 individuals were acquired from the National Health Interview Survey from 2005–2018. Variables included self-reported sleep duration as well as lifetime diagnosis of hypertension, coronary heart disease, diabetes, and pre-diabetes, and obesity. Population-weighted robust Poisson models estimated annual trends in sleep duration and the prevalence risk ratios (PRR) of cardiometabolic disease as a function of sleep duration. SettingPopulation-based survey. ResultsDaily sleep duration decreased -0.62 min ([-0.71, 0.54], p < 0.01) annually from 2005–2018. However, this decline began only after 2010, when sleep duration fell by 1.04 min ([-1.21, -0.86], p < 0.01) each year. This trend varied by race (two-way ANOVA, p = 0.02), such that Mexican Hispanic individuals saw a greater decline (-1.83 [-2.37, -1.30] min per year, p < 0.01) than whites (-0.83 [-1.02, -0.64] min per year, p < 0.01). Additionally, a 1-h loss in daily sleep duration was linked to 4% greater prevalence of hypertension (PRR: 1.04, [1.04, 1.05]), 3% greater prevalence of diabetes (PRR: 1.03 [1.01, 1.05]), and 8% greater prevalence of obesity (PRR: 1.08 [1.07, 1.09]) after adjusting for age, sex, employment, marital status, and survey year. ConclusionsThere is a secular decline in U.S. daily sleep duration that is greater among Mexican Hispanic individuals. Moreover, reduced sleep duration is associated with more prevalent cardiometabolic disease.

Differences in total and regional body fat and their association with BMI in UK-born White and South Asian children: findings from the Born in Bradford birth cohort

Background: Body mass index (BMI) is commonly used as a proxy to determine excess adiposity, though this may underestimate fat mass (FM) in individuals of South Asian (SA) heritage. SA tend to have greater central adiposity than white people, which is associated with a higher risk of cardiometabolic disease. In this cross-sectional study, we aimed to determine the differences in total and regional FM using Dual-energy X-ray absorptiometry (DXA), and to see if any differences in FM varied by BMI category in UK-born white and SA children aged ~9 years. Methods: Anthropometric measurements and DXA scans were undertaken from 225 white and 269 SA children from the Born in Bradford cohort study. Linear regression was used to assess ethnic differences in total body fat percent and total and regional FM. Results: Although mean BMI was similar, compared to white children, the proportion of SA children who were overweight or obese was ~20% higher, and the proportion with &gt; 35% total body fat (TBF) was 22% and 16% higher in boys and girls respectively. Mean TBF% was greater in SA children compared to white children in the same BMI category. Fat mass index (FMI) was higher in all body regions in SA children in all BMI categories; as was total and truncal FMI in healthy and overweight, but not obese, SA children.. Conclusions: Greater TBF% and total and regional FM in SA children suggests they may be at greater risk of future cardiometabolic disease at a BMI level below the obesity threshold. However, our sample size was small, and results may be influenced by selection bias and confounding; our findings need to be replicated in a larger study.

3.D. Workshop: Impact of nutrition on chronic diseases and environment in Europe: evidence and policy orientation

Abstract Over the last decades, unhealthy nutrition has gained visibility as a major driver of the burden of non-communicable chronic diseases (NCDs). The spread of unhealthy foods, characterized by energy-dense, nutrient-poor features, has been called out as mostly responsible for the rise in global and European obesity rates, greatly affecting the younger generations. Public health organizations face major issues in communicating to the target populations, while the general audience is constantly exposed to a substantially obesogenic environment. Moreover, recent scientific literature suggests dietary risks represent the most important behavioral risk factors to impact NCDs. There is convincing evidence that dietary risks are associated with higher risk of cardio-metabolic diseases and certain cancer, which are the main cause of death in Europe. Moreover, certain evidence on under-consumed food groups or nutrients is yet rather underrated and poorly considered from a public health point of view, although leading to a substantial increased risk of disease. Besides the aforementioned health concerns, diet quality may influence food systems and the environment, along with sustainability concerns on the long-term projections. Gathered together, these data emphasize how dietary and nutritional concerns represent a public health issue of gigantic proportion, affecting directly or indirectly the quality of life and mortality rates of European citizens. It is of paramount importance to address this public health issue, to corroborate current evidence of the role of nutrition on health and the environment, and to translate such evidence into advocacy and policy orientation. In this context, the EUPHA Food and Nutrition Section, the Chronic Diseases Section, in collaboration with the World Health Organization (WHO), aim to propose a joint workshop to provide an overview of the impact of nutritional risk factors on obesity and NCDs in Europe, to identify current communication strategies to counteract the burden of disease, to evaluate the environmental impact of the diet, to emphasize on current knowledge and underrated dietary risks, and finally to sum up some work already done at policy level. The organization of this workshop is will provide an important occasion for gathering experts working on this topic of interest and facilitate a dialogue with the audience in light of the presented results. Given the many actors involved, the workshop will provide a unique occasion to discuss about potential policy approaches in the context of the conference. The summary findings from this workshop would help building up common European guidelines for a healthy nutrition. Key messages There is convincing evidence that nutritional guidance toward a healthier diet may reduce the impact of chronic non-communicable diseases. Governmental and non-governmental efforts are needed to advocate for healthier diets in Europe.
