Article Synopsis
  • DBP (Diastolic Blood Pressure) is linked to atherosclerosis and cardiovascular disease, particularly in South Asians, who have elevated risks.
  • The study assessed the relationship between DBP levels and coronary artery calcium (CAC) scores, indicating a higher prevalence of CAC in participants with higher DBP, especially among those not taking antihypertensive medication.
  • The findings suggest that elevated DBP is a significant cardiovascular risk factor in South Asian adults, highlighting the need for awareness and potential interventions.

Introduction: South Asian adults are at high risk for atherosclerotic cardiovascular disease, for which coronary artery calcification is an early predictor. Adherence to the Dietary Approaches to Stop Hypertension diet is a modifiable risk factor that may mitigate the progression of coronary artery calcification and atherosclerotic cardiovascular disease.

Methods: Using data from the Mediators of Atherosclerosis in South Asians Living in America cohort, the authors calculated a Dietary Approaches to Stop Hypertension dietary score (categorized as low, moderate, and high) to examine the associations of Dietary Approaches to Stop Hypertension diet adherence with coronary artery calcification after a 5-year follow up.

Background: The Pooled Cohort Equations (PCEs) do not accurately estimate atherosclerotic cardiovascular disease (ASCVD) risk in certain populations. The 2018 AHA/ACC cholesterol guideline identified risk-enhancing factors as a supplement to PCEs-based risk assessment. However, the role of each risk-enhancing factor in ASCVD risk assessment has not been well quantified.

Background: South Asians (SA) represent the fastest growing US immigrant group, and previous studies have indicated that they face disproportionately high burden of cardiometabolic disease. Cardiometabolic disease manifests as a syndemic or synergistic epidemic encompassing multiple disease clusters influenced by biological, social, and psychological factors stemming from the acculturative process. This process may exacerbate morbidity within immigrant subgroups.

Article Synopsis
  • South Asian adults in the U.S. have a higher prevalence of cardiovascular risk factors like pre-diabetes, diabetes, and hypertension compared to other racial and ethnic groups at younger ages (45-55 years).
  • The study combined data from two major cohort studies to analyze ASCVD risk factors across different races and ethnicities, using participants who were free of clinical ASCVD.
  • Results indicated that at age 45, South Asian men and women exhibited the highest rates for various risk factors and had poorer diet quality compared to other groups, highlighting significant health disparities.

Objective: Circulating microRNAs show cross-sectional associations with overweight and obesity. Few studies provided data to differentiate between a snapshot perspective on these associations versus how microRNAs characterize prodromal risk from disease pathology and complications. This study assessed longitudinal relationships between circulating microRNAs and weight at multiple time-points in the Diabetes Prevention Program trial.

Background: Weight and waist gain are significant concerns in adulthood. Both weight and waist gain are particularly important among South Asians, known to have an increased risk of developing chronic cardiometabolic complications at any body mass index compared to other racial and ethnic groups. The aim of this study was to investigate factors predicting weight and waist gain in a longitudinal cohort of South Asians living in the US (United States).

Few prospective studies examine multilevel resilience resources and psychosocial factors in relation to cardiovascular health and disease. Recent research indicates that resilience resources are associated with a reduction in the incidence of cardiovascular disease-related events, but few studies have examined this relationship across different racial/ethnic populations or in large cohorts. Harmonization may address these limitations because it allows data from several cohorts to be analyzed together, potentially increasing sample size and in turn power overall and in minority populations.

Dementia incidence is lower among Asian Americans than among Whites, despite higher prevalence of type 2 diabetes, a well-known dementia risk factor. Determinants of dementia, including type 2 diabetes, have rarely been studied in Asian Americans. We followed 4846 Chinese, 4129 Filipino, 2784 Japanese, 820 South Asian, and 123 360 non-Latino White members of a California-based integrated health-care delivery system from 2002 to 2020.

Asian Americans have been identified as a racial group that is disproportionately affected by childhood trauma. The goal of this study was  to assess if religion/spirituality moderate the effects of childhood trauma on adult depressive symptoms among a sample of South Asians in the USA. Our analysis drew from the study on stress, spirituality, and health (SSSH) questionnaire fielded in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study (n = 990) during 2016-2018.

South Asian populations have a higher prevalence and earlier age of onset of type 2 diabetes and atherosclerotic cardiovascular diseases than other race and ethnic groups. To better understand the pathophysiology and multilevel risk factors for diabetes and cardiovascular disease, we established the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study in 2010. The original MASALA study cohort (n = 1,164) included 83% Asian Indian immigrants, with an ongoing expansion of the study to include individuals of Bangladeshi and Pakistani origin.
