RESUMO
Asian Americans (AsA), Native Hawaiians, and Pacific Islanders (NHPI) comprise 7.7% of the U.S. population, and AsA have had the fastest growth rate since 2010. Yet the National Institutes of Health (NIH) has invested only 0.17% of its budget on AsA and NHPI research between 1992 and 2018. More than 40 ethnic subgroups are included within AsA and NHPI (with no majority subpopulation), which are highly diverse culturally, demographically, linguistically, and socioeconomically. However, data for these groups are often aggregated, masking critical health disparities and their drivers. To address these issues, in March 2021, the National Heart, Lung, and Blood Institute, in partnership with 8 other NIH institutes, convened a multidisciplinary workshop to review current research, knowledge gaps, opportunities, barriers, and approaches for prevention research for AsA and NHPI populations. The workshop covered 5 domains: 1) sociocultural, environmental, psychological health, and lifestyle dimensions; 2) metabolic disorders; 3) cardiovascular and lung diseases; 4) cancer; and 5) cognitive function and healthy aging. Two recurring themes emerged: Very limited data on the epidemiology, risk factors, and outcomes for most conditions are available, and most existing data are not disaggregated by subgroup, masking variation in risk factors, disease occurrence, and trajectories. Leveraging the vast phenotypic differences among AsA and NHPI groups was identified as a key opportunity to yield novel clues into etiologic and prognostic factors to inform prevention efforts and intervention strategies. Promising approaches for future research include developing collaborations with community partners, investing in infrastructure support for cohort studies, enhancing existing data sources to enable data disaggregation, and incorporating novel technology for objective measurement. Research on AsA and NHPI subgroups is urgently needed to eliminate disparities and promote health equity in these populations.

BACKGROUND: The evidence linking sugar-sweetened beverage (SSB) intake and mortality risk is conflicting, and associations between various SSB subtypes and mortality remain unclear. OBJECTIVE: To examine the association between baseline SSB intake, subtypes of SSB intake, and mortality risk in women. DESIGN: Prospective cohort study. PARTICIPANTS/SETTING: Participants of the California Teachers Study (n = 100,314; median age = 53 years) free of cardiovascular disease, cancer, and diabetes at baseline (1995-1996) were followed from 1995 to 2015. Baseline SSB intake was defined as caloric soft drinks (regular soft drinks, not diet soda), sweetened bottled waters or teas, and fruit drinks; and was derived from a self-administered food frequency questionnaire. MAIN OUTCOME MEASURE: Mortality was ascertained via annual linkage with state- and nationwide mortality records and the National Death Index over 20 years. STATISTICAL ANALYSIS: Multivariable-adjusted Cox proportional hazards models were used to generate hazard ratios (HRs) and 95% CIs for assessing associations between SSB intake and mortality. Rare/never consumers were the comparator group. RESULTS: There were a total of 14,143 deaths over 20 years (30.5% from cardiovascular disease; 29.2% from cancer). In women who consumed ≥ 7 servings/week of SSBs at baseline (4% of participants), the multivariable-adjusted HRs were not significant for all-cause, cardiovascular disease-specific, or cancer-specific mortality. Consuming ≥ 7 servings/week of baseline caloric soft drink was associated with a higher risk of all-cause (HR = 1.26, 95% CI 1.10 to 1.46; P for trend = 0.02) and cancer-specific (HR = 1.33, 95% CI 1.08 to 1.63; P for trend = 0.08) mortality. In secondary analyses, consuming ≥ 1.5 c/day of baseline SSBs was associated with all-cause mortality (HR = 1.12, 95% CI 1.02 to 1.24; P for trend = 0.01). CONCLUSIONS: Although the baseline frequency of total SSB intake was not significantly associated with mortality, consuming ≥ 7 servings/week of caloric soft drinks was associated with higher risk of all-cause and cancer-specific mortality. Findings support public health efforts to reduce caloric soft drink consumption.

BACKGROUND: The association between sugar-sweetened beverage (SSB) consumption and colorectal cancer (CRC) risk remains unclear and published data are limited. METHODS: The analytic cohort included 99,798 women, free of cancer at baseline, from the California Teachers Study, a longitudinal cohort comprised of 133,477 female teachers and administrators who were active or recently retired members of the California State Teachers Retirement System in 1995. SSB consumption constituted caloric soft drinks, sweetened bottled waters and teas, and fruit drinks, derived from a self-administered food frequency questionnaire. Consumption was divided into four categories: Rare or never, >rare/never to <1 serving/week, ≥1 serving/week to <1 serving/day, and ≥1 serving/day. CRC endpoints were based on annual linkage with California Cancer Registry, defined as first diagnosis of CRC, and classified following the Surveillance, Epidemiology, and End Results Program coding system. Multivariable-adjusted Cox proportional hazards models were used to generate hazard ratios (HR) and 95% confidence intervals (CI) for assessing the association between SSB consumption and incident CRC. RESULTS: A total of 1,318 incident CRC cases were identified over 20 years of follow-up (54.5% proximal colon and 45.5% distal colorectum). Compared with rare/never consumers, the multivariable-adjusted HRs (95% CI) were 1.14 (0.86, 1.53) for total CRC; 1.11 (0.73, 1.68) for proximal colon; and 1.22 (0.80, 1.86) for distal colorectum cancers among women consuming ≥ 1 serving/day of SSBs. CONCLUSION: SSBs were not significantly associated with CRC risk. The biological effects of high SSB consumption make it important to continue to evaluate whether SSBs are associated with CRC. Additionally, future studies should further assess SSBs in large, racial/ethnically diverse cohorts of males and females, and, if feasible, address changes in SSB consumption over time.

AIMS: To investigate the utility of the body adiposity index (BAI) and its association with the metabolic syndrome (MetS) in older Caucasian (n=369), African American (n=336) and Filipina (n=275) women. METHODS: Dual energy X-ray absorptiometry, anthropometric measures, plasma glucose and medical history were assessed in 1993-1999. RESULTS: Despite smaller body size, 32.7% of Filipina women had higher MetS compared to African American and Caucasian women based on the National Cholesterol Education Program (NCEP) (32.7% vs 19.6% and 13.3%, respectively) or the International Diabetes Federation (IDF) (42.6% vs 33.0% and 18.7%, respectively ps<0.05). BAI had higher positive correlations with BMI, %body fat (%BF), and %truncal fat in Caucasian than African American and Filipina women. Adjusted for age, smoking, estrogen use, exercise, and alcohol intake, odds of the MetS (NCEP) were 2.08 (95%CI: 1.52-2.85) by BAI, 3.04 (95%CI: 2.11-4.38) by BMI, and 2.13 (95%CI: 1.52-3.00) by %BF for Caucasian women; 0.92 (95%CI: 0.69-1.23) by BAI, 1.44 (95%CI: 1.09-1.90) by BMI, and 1.12 (95%CI: 0.84-1.50) by %BF for African American women; and 1.14 (95%CI: 0.88-1.47) by BAI, 1.51 (95%CI: 1.15-1.97) by BMI, and 0.96 (95%CI: 0.74-1.25) by %BF for Filipinas. CONCLUSION: BAI was better able to assess adiposity in postmenopausal Caucasian women compared to African American and Filipina women. This index can distinguish ethnic differences in MetS confirmed by %BF.

CONTEXT: Despite the key role of muscle in glucose regulation, little is known about the association between muscle area and prevalence of metabolic disorders, or the role low muscle may play in normal weight metabolic obesity. OBJECTIVE: The objective was to assess the independent associations between both abdominal muscle and fat depositions (measured by computed tomography) and the prevalence of type II diabetes, and to explore the modifying role of weight category. DESIGN: We conducted a cross-sectional analysis of the 2001-2002 visit for the Rancho Bernardo Study, Filipino Women's Health Study, and Health Assessment Study of African American Women. SETTING AND PARTICIPANTS: Participants were 392 community-dwelling older women (mean age = 64) free of clinical cardiovascular disease. MAIN OUTCOME MEASURE: The main outcome was prevalence of type II diabetes, defined as use of anti-diabetes medication, fasting plasma glucose ≥ 126 mg/dL, and/or OGTT ≥ 200 mg/dL. RESULTS: Adjusting for demographics, hypertension, estrogen use, lipids, smoking, physical activity, visceral fat area, and height, a greater muscle-to-total abdominal area ratio (MAR) was associated with lower odds of diabetes [OR = 0.63 per standard deviation, 95% CI (0.43-0.92), p = .02]. Higher visceral fat was associated with greater odds of diabetes in fully adjusted models including total muscle area [OR = 1.48, 95% CI (1.09, 2.01), p = .01]. Associations between MAR and diabetes were stronger for normal weight (BMI 18.5-24.9; OR = 0.32) than overweight/obese women (BMI ≥ 25, OR = 0.71, p-for-interaction = 0.046). Associations with visceral fat did not differ by BMI (p-for-interaction = 0.71). CONCLUSIONS: In older women, abdominal muscle area is inversely associated with type II diabetes independent of visceral adiposity, particularly for normal weight women.

Elevated serum uric acid (UA) is associated with cardiovascular disease (CVD) but its association with coronary artery calcium (CAC) is inconsistent. This study examined ethnic differences in the association of UA levels with CAC severity and progression. Participants included 202 white and 166 Filipino postmenopausal women without known CVD. White women originated from the Rancho Bernardo cohort study, whereas Filipino women were convenience sampled from comparable localities. Baseline UA levels and CVD risk factors were measured in 1995 to 1999. CAC was assessed by electron beam computed tomography (EBCT) in 2000 to 2002 (EBCT1) and repeated in 2005 to 2007 (EBCT2). EBCT1 CAC density scores were categorized by severity: minimal 0 to 10, mild 11 to 100, moderate 101 to 399, and severe ≥400. Progression was defined as CAC volume score increases of ≥2.5 mm3 between scans. White women were older at baseline than Filipinas (64.6 vs 59.3 years, p<0.001). Filipinas had increased UA levels (235.8 vs 294.2 µmol/L, p<0.001), diabetes (35.5% vs 5.2%, p<0.001), hypertension (69.6% vs 45.2%, p<0.001), and statin use (32.8% vs 18.7%, p=0.002). CAC severity did not vary by ethnicity (p=0.502), but Filipinas experienced more CAC progression than whites (53.0% vs 39.1%, p=0.016). Adjustment for CVD risk factors identified a positive association between UA levels and increasing CAC severity at EBCT1 in Filipinas (odds ratio [OR] 1.34, 95% confidence interval [CI] 1.05 to 1.71) but not whites (OR 0.94, 95% CI 0.71 to 1.25). Higher UA levels predicted CAC progression in both cohorts (OR 1.26, 95% CI 1.02 to 1.56). In conclusion, these results support use of UA as an ethnicity-specific marker of CAC severity and as a marker of CAC progression among postmenopausal women.

INTRODUCTION: Increased sedentary behavior predicts greater cardiovascular morbidity and mortality and does so independently of physical activity (PA). This association is only partially explained by body mass index (BMI) and overall body fat, suggesting mechanisms besides general increased adiposity. The purpose of this study was to explore associations of self-reported leisure PA and sitting time with regional fat depositions and abdominal muscle among community-dwelling older adults. METHODS: Participants were 539 diverse adults (mean age = 65 yr) who completed a study visit in 2001-2002. Areas of pericardial, intrathoracic, subcutaneous, visceral, and intermuscular fat, as well as abdominal muscle, were measured using computed tomography. Leisure PA and sitting hours were entered simultaneously into multivariate regression models to determine associations with muscle and fat areas. RESULTS: After adjusting for demographics, smoking, diabetes, hypertension, triglycerides, and cholesterol, greater PA was associated with less intrathoracic, visceral, subcutaneous, and intermuscular fat (for all P < 0.05), while greater sedentary time was associated with greater pericardial and intrathoracic fat (for both P < 0.05). After further adjusting for BMI, each hour of weekly PA was associated with 1.85 cm less visceral fat (P < 0.01) but was not associated with other fat depositions. Conversely, each hour of daily sitting was associated with 2.39 cm more pericardial fat (P < 0.05) but was not associated with any other fat depositions. There were no associations with abdominal muscle area. Adjusting for common inflammatory markers had little effect. Associations between fat and PA were stronger for men. CONCLUSIONS: Sitting and PA have distinct associations with regional fat deposition in older adults. The association between sitting and pericardial fat could partially explain the link between sitting and coronary heart disease.

OBJECTIVE: Body mass index (BMI) may not accurately or adequately reflect body composition or its role in the development of cardiovascular disease (CVD). Ectopic adipose depots may provide a more refined representation of the role of adiposity in CVD. Thus, the association of pericardial and intra-thoracic fat with coronary artery calcium (CAC) was examined. DESIGN AND METHODS: Nearly 600 white men and women, as well as Filipina women and African-American women, all without known CVD, had abdominal and chest computed tomography (CT) scans at two time points about 4 years apart from which CAC presence, severity and progression, as well as pericardial and intrathoracic fat volumes were obtained. Logistic and linear regression models with staged adjustment were used to assess associations of pericardial and intra-thoracic fat with CAC presence, severity, and progression. RESULTS: After adjustment for age, BMI, sex/ethnic group, ever smoking, and lipids, each standard deviation higher increment of intra-thoracic fat, but not pericardial fat, was significantly associated with 3.84-fold higher odds of prevalent CAC (95% CI (1.54, 9.58), P = 0.004) and a 38.4% higher CAC score (95% CI (3.5%, 90.0%), P = 0.03). Neither pericardial nor intrathoracic fat were associated with CAC progression. CONCLUSIONS: Contrary to previous reports, pericardial fat was not associated with the presence, severity or progression of CAC. However, a significant association between intrathoracic fat and both the presence and severity of CAC was demonstrated. Studies measuring fat in the thoracic cavity may consider defining intrathoracic fat as a separate entity from pericardial fat.

BACKGROUND: Studies have shown alanine aminotransferase (ALT), a marker for non-alcoholic fatty liver disease (NAFLD), predicts type 2 diabetes (T2DM). OBJECTIVE: To examine the association between probable NAFLD and T2DM in non-obese, non-alcoholic consuming Filipino-American women aged 48-73 years. RESEARCH DESIGN AND METHODS: The UCSD Filipino Women's Health Study measured glucose, hepatic enzymes, adiponectin and visceral fat (VAT) during clinical visits (1995-2002). We defined T2DM by 1999 WHO criteria and probable NAFLD as ALT >31 U/L. RESULTS: Prevalence of T2DM was 34.4% and probable NAFLD was 17.2%. Women with T2DM (n=56) had higher VAT, total:HDL cholesterol, SBP, fasting glucose and insulin, postchallenge glucose, ALT (28.7 U/L versus 19.1 U/L, p<0.0001), GGT, AST, and probable NAFLD (32.1% versus 9.35%, p=0.0002) and lower adiponectin than those without T2DM (n=107). GGT (p=0.0008) and ALT (p=0.002) were associated with increasing VAT levels. Probable NAFLD was independently associated with T2DM (AOR 6.32, 95% CI 2.2-18.0), after adjusting for risk factors. CONCLUSION: Probable NAFLD was elevated and associated with T2DM, independent of VAT, adiponectin and other risk factors. ALT may serve as a useful marker for NAFLD or diabetes risk in Filipino women.

Previous studies of leptin with cardiovascular disease (CVD) risk factors have been limited by clinical samples or lack of representation of the general population. This cross-sectional study, designed to examine whether leptin or insulin may mediate the endogenous relation of obesity with metabolic, inflammatory, and thrombogenic cardiovascular risk factors, included 522 men and 514 women aged >or=40 years who completed a physical examination during the third National Health and Nutrition Examination Survey. Participants were free of existing CVD, cancer (except non-melanoma skin cancer), diabetes, or respiratory disease. In multivariable analyses adjusted for race/ethnicity and lifestyle factors, waist circumference (WC) was positively associated with blood pressure, triglyceride, LDL cholesterol, total cholesterol:HDL ratio, apolipoprotein B, C-reactive protein (CRP), and fibrinogen concentrations, and negatively associated with HDL cholesterol and apolipoprotein A1 levels. The associations of WC with the metabolic CVD risk factors were largely attenuated after adjustment for insulin levels, while the associations of WC with the inflammatory and thrombogenic factors (CRP and fibrinogen, respectively) were largely explained by adjustment for leptin concentrations. However, leptin levels were not independently associated with CRP and fibrinogen in men and CRP in women when adjusted for WC. Positive associations of leptin and insulin with fibrinogen in women, independent of WC, were noted. These results suggest that insulin may be an important mediator of the association of obesity with metabolic but not inflammatory or thrombogenic CVD risk factors, while leptin does not appear to influence cardiovascular risk through a shared association with these risk factors. However, we cannot rule out the possibility that leptin and insulin influence cardiovascular risk in women through independent effects on fibrinogen concentrations.

OBJECTIVE: To investigate associations between adult markers of childhood growth and the prevalence of diabetes and coronary heart disease (CHD) in Filipino-American women and to determine the role of social and educational differences, including the influence of social mobility between childhood and adulthood. RESEARCH DESIGN AND METHODS: Socioeconomic disadvantage and poor infant growth, resulting in short leg length, may contribute to the dramatically increased risk of diabetes and CHD in Filipino-American women, but this has not been investigated. This study is a cross-sectional study of 389 Filipino-American women (age 58.7 +/- 9.4 years [mean +/- SD]). Diabetes was defined by 1999 World Health Organization criteria and CHD by ischemic electrocardiogram changes, Rose angina, a history of myocardial infarction, or revascularization surgery. A score of social mobility (0-4) was calculated by summarizing childhood and adult financial circumstances. RESULTS: Diabetes prevalence (31.4%) was not associated with measures of growth but was significantly lower in women with greater education, childhood and adult income, or social mobility score. Compared with Filipinas who were poorest in childhood and adulthood, respective odds ratios (95% CI) for diabetes were 0.55 (0.18-1.68), 0.19 (0.06-0.62), and 0.11 (0.03-0.42), down to 0.07 (0.01-0.51) in the most advantaged women (P < 0.0001). Family history of diabetes [5.14 (2.72-9.70)] and larger waist [1.07 per cm (1.03-1.10)] were also significant predictors in multiple adjusted models. In contrast, CHD prevalence (22.4%) was most strongly associated with leg length, but not trunk length; compared with individuals with the shortest legs, respective odds ratios (95% CI) for CHD were 0.60 (0.31-1.19), 0.53 (0.26-1.05), and 0.44 (0.22-0.91) in the tallest group, in age- (P(trend) = 0.02) and multiple-adjusted models (P(trend) = 0.01). CONCLUSIONS: Socioeconomic disadvantage contributes to the high prevalence of diabetes in Filipinas. Factors limiting early growth of the legs may increase the risk of CHD in this comparatively short population.

BACKGROUND: Coronary heart disease (CHD) is the leading cause of morbidity and mortality in persons with type 2 diabetes mellitus (T2DM). Electron-beam computed tomography (EBCT) detects coronary artery calcium (CAC), a marker of atherosclerotic plaque. Few studies have described EBCT-defined CHD among ethnic minorities with elevated T2DM prevalence. The objective of this study was to compare EBCT-defined CAC in Filipino and white women without known cardiovascular disease. METHODS AND RESULTS: Subjects were participants aged 55 to 78 years in the Rancho Bernardo Study (n=196) and the University of California at San Diego's Filipino Women's Health Study (n=181). Glucose, blood pressure, lipids, anthropometric measurements, and lifestyle factors were measured from 1995 to 1999. EBCT-defined CAC scores, visceral and subcutaneous fat, and statin use were assessed in 2001 to 2002. Compared with whites, Filipinas had a significantly higher prevalence of T2DM (32.6% versus 6.1%, P<0.001) and the metabolic syndrome (32.6% versus 13.8, P<0.001). Filipinas were younger (64.4 versus 66.7 years), had higher triglyceride levels (155 versus 135 mg/dL), had a higher ratio of total cholesterol to HDL cholesterol (4.3 versus 3.5), more frequently used statins (31% versus 19%), and had more visceral fat (69.4 versus 62.1 cm3) and lower HDL cholesterol levels (54 versus 66 mg/dL) than whites. Exercise frequency, body mass index, and waist girth did not differ by ethnicity. Nevertheless, extensive (CAC score > or =400; 9% versus 9%) and moderate (CAC score 150 to 399; 13% versus 11%) atherosclerotic plaque did not differ by ethnicity, even after adjustment for age, T2DM, hypertension, estrogen use, statin use, smoking, lipids, and visceral fat. CONCLUSIONS: Filipinas had no excess of subclinical atherosclerosis despite their significantly higher prevalence of T2DM, the metabolic syndrome, hypertension, and visceral adiposity.

OBJECTIVE: To compare the prevalence of type 2 diabetes and features of the metabolic syndrome among Filipina and Caucasian women in San Diego County, California. RESEARCH DESIGN AND METHODS: Data on several chronic diseases were collected between 1992 and 1999 from community-dwelling Filipina (n=294) and Caucasian (n=379) women aged 50-69 years. RESULTS: Filipina and Caucasian women did not differ in mean age (59.7 vs. 60 years, respectively), BMI (25.6 vs. 25.4 kg/m(2)), percentage of body fat (33.5 vs. 34.2%), or waist-to-hip ratio (0.84 vs. 0.83), although Filipinas had larger waist circumferences and higher percentages of truncal fat. Compared with Caucasians, Filipinas were less likely to be obese (BMI > or = 30 kg/m(2), 8.8 vs. 14%, P=0.04) and less likely to smoke, consume alcohol, or take postmenopausal estrogen; Filipinas also had lower levels of HDL cholesterol. Compared with Caucasians, Filipinas had higher prevalence of type 2 diabetes by oral glucose tolerance test criteria (36 vs. 9%) and the metabolic syndrome (34 vs. 13%). These differences persisted after adjusting for age, body size, fat distribution, percentage of body fat, smoking, alcohol consumption, exercise, and estrogen therapy. CONCLUSIONS: A total of 10% of Filipinas with diabetes were obese, compared with one third of Caucasians with diabetes. The finding of a high prevalence of diabetes in an unstudied nonobese ethnic group reinforces the importance of expanding the study of diabetes to diverse populations. The high prevalence of diabetes in populations who are not of Northern European ancestry may be missed when they are not obese by Western standards.
