Glycaemic responses to liquid food supplements among three Asian ethnic groups.

ABSTRACT: A limited number of studies have compared the glycaemic index (GI) and glycaemic responses (GR) to solid foods between Caucasians and Asians. These studies have demonstrated that Asians have greater GI and GR values for solid foods than Caucasians. However, no study has compared the GI and GR to liquids among various Asian ethnic groups.A total of forty-eight males and females (16 Chinese, 16 Indians, and 16 Malay) took part in this randomised, crossover study. Glycaemic response to the reference food (glucose beverage) was measured on three occasions, and GR to three liquids were measured on one occasion each. Liquids with different macronutrient ratio's and carbohydrate types were chosen to be able to evaluate the response to products with different GIs. Blood glucose concentrations were measured in duplicate at baseline (-5 and 0 min) and once at 15, 30, 45, 60, 90, and 120 min after the commencement of beverage consumption.There were statistically significant differences in GI and GR between the three liquids (P < 0.01 in all cases). However, there were no statistically significant differences in GI and GR for the liquids between the ethnic groups (Chinese vs. Indian vs. Malay).The GR for three different types of liquid nutritional supplements did not differ between the three main ethnic groups in Asia. It appears that the GI of liquid food derived from one Asian ethnicity can be applicable to other Asian populations.

Project description:PurposeTo determine the incidence and prevalence of different glaucoma types among Asian Americans and other races, and evaluate the hazard for glaucoma among different races and Asian ethnicities.DesignRetrospective, longitudinal, cohort study.ParticipantsA group of 2,259,061 eye care recipients, aged ? 40, who were enrolled in a US managed-care network in 2001-2007.MethodsIncidence and prevalence rates of open-angle glaucoma (OAG), narrow-angle glaucoma (NAG), and normal-tension glaucoma (NTG) were calculated and stratified by race and Asian ethnicity. Cox regression was performed to assess the hazard of developing OAG, NAG, and NTG for Asian Americans and other races, and among different Asian ethnicities, with adjustment for potentially confounding variables.Main outcome measuresMultivariable adjusted hazard of OAG, NAG, and NTG among different races and Asian ethnicities.ResultsThe OAG prevalence rate for Asian Americans, 6.52%, was similar to that of Latinos (6.40%) and higher than that of non-Hispanic whites (5.59%). The NAG and NTG prevalence rates were considerably higher among Asian Americans (3.01% and 0.73%, respectively) relative to other races. After adjustment for potential confounding factors, Asian Americans had a 51% increased hazard of OAG (adjusted hazard ratio [HR], 1.51 [95% confidence interval (CI), 1.42-1.60]), a 123% increased hazard of NAG (adjusted HR, 2.23; CI, 2.07-2.41), and a 159% increased hazard of NTG (adjusted HR, 2.59; CI, 2.22-3.02) compared with non-Hispanic whites. Vietnamese Americans (adjusted HR, 3.78; CI, 3.19-4.48), Pakistani Americans (adjusted HR, 2.45, CI 1.50-4.01), and Chinese Americans (adjusted HR, 2.31, CI 2.06-2.59) had considerably higher hazards of NAG, whereas Japanese Americans (adjusted HR, 4.37, CI 3.24-5.89) had a substantially higher hazard of NTG, compared with non-Asian Americans.ConclusionsGiven the rapid rise in the number of Asian Americans in the US population, resources should be devoted to identifying and treating glaucoma in these patients. Eye-care providers should be aware of the increased risk for OAG, NAG, and NTG among Asian Americans relative to other races. Knowing Asian-American patients' ancestral country of origin may permit more precise estimation of their risks for OAG, NAG, and NTG.Financial disclosure(s)The authors have no proprietary or commercial interest in any materials discussed in this article.

Project description:BackgroundWesternization and etiologic heterogeneity may play a role in the rising breast cancer incidence in Asian American (AA) women. We report breast cancer incidence in Asian-origin populations.MethodsUsing a specialized Surveillance, Epidemiology, and End Results-9 Plus API Database (1990-2014), we analyzed breast cancer incidence overall, by estrogen receptor (ER) status, and age group among non-Hispanic white (NHW) and AA women. We used age-period-cohort models to assess time trends and quantify heterogeneity by ER status, race and ethnicity, and age.ResultsOverall, breast cancer incidence increased for most AA ethnicities (Filipina: estimated annual percentage change [EAPC] = 0.96%/year, 95% confidence interval [CI] = 0.61% to 1.32%; South Asian: EAPC = 1.68%/year, 95% CI = 0.24% to 3.13%; Chinese: EAPC = 0.65%/year, 95% CI = 0.03% to 1.27%; Korean: EAPC = 2.55%/year, 95% CI = 0.13% to 5.02%; and Vietnamese women: EAPC = 0.88%/year, 95% CI = 0.37% to 1.38%); rates did not change for NHW (EAPC = -0.2%/year, 95% CI = -0.73% to 0.33%) or Japanese women (EAPC = 0.22%/year, 95% CI = -1.26% to 1.72%). For most AA ethnicities, ER-positive rates statistically significantly increased, whereas ER-negative rates statistically significantly decreased. Among older women, ER-positive rates were stable for NHW and Japanese women. ER-negative rates decreased fastest in NHW and Japanese women among both age groups.ConclusionsIncreasing ER-positive incidence is driving an increase overall for most AA women despite declining ER-negative incidence. The similar trends in NHW and Japanese women (vs other AA ethnic groups) highlight the need to better understand the influences of westernization and other etiologic factors on breast cancer incidence patterns in AA women. Heterogeneous trends among AA ethnicities underscore the importance of disaggregating AA data and studying how breast cancer differentially affects the growing populations of diverse AA ethnic groups.
