Physical activity according to diabetes and metropolitan status: United States 2020 and 2022
Onufrak S , Saelee R , Zaganjor I , Miyamoto Y , Koyama AK , Xu F , Pavkov ME . Am J Prev Med 2024 INTRODUCTION: Physical activity (PA) can reduce morbidity and mortality among adults with diabetes. While rural disparities in PA exist among the general population, it is not known how these disparities manifest among adults with diabetes. METHODS: Data from the 2020 and 2022 National Health Interview Survey were analyzed in 2023 to assess prevalence of meeting aerobic and muscle-strengthening recommendations according to the 2018 Physical Activity Guidelines for Americans during leisure time. PA prevalence was computed by diabetes status, type of PA, and urban/rural residence (large central metro, large fringe metro, medium/small metro, and non-metro). Logistic regression models were used to estimate prevalence and prevalence ratios of meeting PA recommendations by urban/rural residence across diabetes status. RESULTS: Among adults with diabetes in non-metro counties, only 23.8% met aerobic, 10.9% met muscle-strengthening, and 6.2% met both PA recommendations. By contrast, among adults with diabetes in large fringe metro counties, 32.1% met aerobic, 19.7% met strengthening, and 12.0% met both guidelines. Multivariable adjusted prevalence of meeting muscle-strengthening recommendations was higher among participants with diabetes in large fringe metro compared to large central metro counties (PR=1.27; 95% CI 1.03-1.56). Among those without diabetes, adjusted prevalence of meeting each recommendation or both was lower in non-metro and small/medium metro compared to large central metro counties. CONCLUSIONS: Adults with diabetes are less likely to meet the PA recommendations than those without, and differences exist according to urban/rural status. Improving PA among rural residents with diabetes may mitigate disparities in diabetes-related mortality. |
Prevalence of cardiometabolic diseases among racial and ethnic subgroups in adults - Behavioral Risk Factor Surveillance System, United States, 2013-2021
Koyama AK , McKeever Bullard K , Xu F , Onufrak S , Jackson SL , Saelee R , Miyamoto Y , Pavkov ME . MMWR Morb Mortal Wkly Rep 2024 73 (3) 51-56 Although diabetes and cardiovascular disease account for substantial disease prevalence among adults in the United States, their prevalence among racial and ethnic subgroups is inadequately characterized. To fill this gap, CDC described the prevalence of diagnosed cardiometabolic diseases among U.S. adults, by disaggregated racial and ethnic subgroups, among 3,970,904 respondents to the Behavioral Risk Factor Surveillance System during 2013-2021. Prevalence of each disease (diabetes, myocardial infarction, angina or coronary heart disease, and stroke), stratified by race and ethnicity, was based on self-reported diagnosis by a health care professional, adjusting for age, sex, and survey year. Overall, mean respondent age was 47.5 years, and 51.4% of respondents were women. Prevalence of cardiometabolic diseases among disaggregated race and ethnicity subgroups varied considerably. For example, diabetes prevalence within the aggregated non-Hispanic Asian category (11.5%) ranged from 6.3% in the Vietnamese subgroup to 15.2% in the Filipino subgroup. Prevalence of angina or coronary heart disease for the aggregated Hispanic or Latino category (3.8%) ranged from 3.1% in the Cuban subgroup to 6.3% in the Puerto Rican subgroup. Disaggregation of cardiometabolic disease prevalence data by race and ethnicity identified health disparities among subgroups that can be used to better help guide prevention programs and develop culturally relevant interventions. |
Risk factors amenable to primary prevention of type 2 diabetes among disaggregated racial and ethnic subgroups in the U.S.
Koyama AK , Bullard KM , Onufrak S , Xu F , Saelee R , Miyamoto Y , Pavkov ME . Diabetes Care 2023 46 (12) 2112-2119 OBJECTIVE: Race and ethnicity data disaggregated into detailed subgroups may reveal pronounced heterogeneity in diabetes risk factors. We therefore used disaggregated data to examine the prevalence of type 2 diabetes risk factors related to lifestyle behaviors and barriers to preventive care among adults in the U.S. RESEARCH DESIGN AND METHODS: We conducted a pooled cross-sectional study of 3,437,640 adults aged ≥18 years in the U.S. without diagnosed diabetes from the Behavioral Risk Factor Surveillance System (2013-2021). For self-reported race and ethnicity, the following categories were included: Hispanic (Cuban, Mexican, Puerto Rican, Other Hispanic), non-Hispanic (NH) American Indian/Alaska Native, NH Asian (Chinese, Filipino, Indian, Japanese, Korean, Vietnamese, Other Asian), NH Black, NH Pacific Islander (Guamanian/Chamorro, Native Hawaiian, Samoan, Other Pacific Islander), NH White, NH Multiracial, NH Other. Risk factors included current smoking, hypertension, overweight or obesity, physical inactivity, being uninsured, not having a primary care doctor, health care cost concerns, and no physical exam in the past 12 months. RESULTS: Prevalence of hypertension, lifestyle factors, and barriers to preventive care showed substantial heterogeneity among both aggregated, self-identified racial and ethnic groups and disaggregated subgroups. For example, the prevalence of overweight or obesity ranged from 50.8% (95% CI 49.1-52.5) among Chinese adults to 79.8% (73.5-84.9) among Samoan adults. Prevalence of being uninsured among Hispanic subgroups ranged from 11.4% (10.9-11.9) among Puerto Rican adults to 33.0% (32.5-33.5) among Mexican adults. CONCLUSIONS: These findings underscore the importance of using disaggregated race and ethnicity data to accurately characterize disparities in type 2 diabetes risk factors and access to care. |
Change in testing for blood glucose during the COVID-19 pandemic, United States 2019–2021
Miyamoto Y , Saelee R , Koyama AK , Zaganjor I , Xu F , Onufrak S , Pavkov ME . Diabetes Res Clin Pract 2023 205 Aim: This study assessed changes in testing for blood glucose in the United States (US) from 2019 to 2021. Methods: We conducted a serial cross-sectional analysis of the 2019–2021 National Health Interview Survey by including adults aged ≥ 18 years without reported diagnosed diabetes. We estimated the prevalence of testing for blood glucose within 12 months and the difference in the testing prevalence between 2019 and 2021. Results: The study sample included 82,594 respondents without diabetes in 2019––2021, with a mean age between 46.4 and 46.8 years. Overall, the prevalence of testing for blood glucose decreased significantly from 64.2 % (95 % confidence interval [CI] 63.3 %, 65.1 %) in 2019 to 60.0 % (95 % CI 59.1 %, 60.9 %) in 2021. Among adults who met the United States Preventive Services Task Force's 2015 screening recommendation, the prevalence decreased from 73.4 % (95 % CI 72.2 %, 74.6 %) to 69.5 % (95 % CI 68.3 %, 70.6 %). Although decreases in testing were observed in most groups, the extent of the decline differed by subgroups. Conclusions: Testing for blood glucose decreased in the US during the COVID-19 pandemic. This may have delayed diagnosis and treatment of prediabetes and diabetes, underscoring the importance of continued access to diabetes screening during pandemics. © 2023 |
Comparison between the triglycerides standardization of routine methods used in Japan and the chromotropic acid reference measurement procedure used by the CDC Lipid Standardization Programme
Nakamura M , Iso H , Kitamura A , Imano H , Noda H , Kiyama M , Sato S , Yamagishi K , Nishimura K , Nakai M , Vesper HW , Teramoto T , Miyamoto Y . Ann Clin Biochem 2016 53 (6) 632-639 Background The US Centers for Disease Control and Prevention ensured adequate performance of the routine triglycerides methods used in Japan by a chromotropic acid reference measurement procedure used by the Centers for Disease Control and Prevention lipid standardization programme as a reference point. We examined standardized data to clarify the performance of routine triglycerides methods. Methods The two routine triglycerides methods were the fluorometric method of Kessler and Lederer and the enzymatic method. The methods were standardized using 495 Centers for Disease Control and Prevention reference pools with 98 different concentrations ranging between 0.37 and 5.15 mmol/L in 141 survey runs. The triglycerides criteria for laboratories which perform triglycerides analyses are used: accuracy, as bias ≤5% from the Centers for Disease Control and Prevention reference value and precision, as measured by CV, ≤5%. Results The correlation of the bias of both methods to the Centers for Disease Control and Prevention reference method was: y (%bias) = 0.516 x (Centers for Disease Control and Prevention reference value) -1.292 ( n = 495, R2 = 0.018). Triglycerides bias at medical decision points of 1.13, 1.69 and 2.26 mmol/L was -0.71%, -0.42% and -0.13%, respectively. For the combined precision, the equation y (CV) = -0.398 x (triglycerides value) + 1.797 ( n = 495, R2 = 0.081) was used. Precision was 1.35%, 1.12% and 0.90%, respectively. It was shown that triglycerides measurements at Osaka were stable for 36 years. Conclusions The epidemiologic laboratory in Japan met acceptable accuracy goals for 88.7% of all samples, and met acceptable precision goals for 97.8% of all samples measured through the Centers for Disease Control and Prevention lipid standardization programme and demonstrated stable results for an extended period of time. |

Nakamura M , Yokoyama S , Kayamori Y , Iso H , Kitamura A , Okamura T , Kiyama M , Noda H , Nishimura K , Nakai M , Koyama I , Dasti M , Vesper HW , Teramoto T , Miyamoto Y . Clin Chim Acta 2015 439 185-90 BACKGROUND: Accurate high-density lipoprotein cholesterol (HDL-C) measurements are important for management of cardiovascular diseases. The US Centers for Disease Control and Prevention (CDC) and Cholesterol Reference Method Laboratory Network (CRMLN) perform ultracentrifugation (UC) reference measurement procedure (RMP) to value assign HDL-C. Japanese CRMLN laboratory (Osaka) concurrently runs UC procedure and the designated comparison method (DCM). Osaka performance of UC and DCM was examined and compared with CDC RMP. METHODS: CDC RMP involved UC, heparin-MnClâ‚‚ precipitation, and cholesterol analysis. CRMLN DCM for samples containing <200 mg/dl triglycerides involved 50-kDa dextran sulfate-MgCl2 precipitation and cholesterol determination. RESULTS: HDL-C regression equations obtained with CDC (x) and Osaka (y) were y=0.992x+0.542 (R(2)=0.996) for Osaka UC and y=1.004x-0.181 (R(2)=0.998) for DCM. Pass rates within ±1 mg/dl of the CDC target value were 91.9 and 92.1% for Osaka UC and DCM, respectively. Biases at 40 mg/dl HDL-C were +0.22 and -0.02 mg/dl for Osaka UC and DCM, respectively. CONCLUSIONS: Osaka UC and DCM were highly accurate, precise, and stable for many years, assisting manufacturers to calibrate products for clinical laboratories to accurately measure HDL-C for patients, calculate non-HDL-C, and estimate low-density lipoprotein cholesterol with the Friedewald equation. |

Nakamura M , Iso H , Kitamura A , Imano H , Kiyama M , Yokoyama S , Kayamori Y , Koyama I , Nishimura K , Nakai M , Dasti M , Vesper HW , Miyamoto Y . Clin Chim Acta 2015 445 127-32 BACKGROUND: Accurate measurement of total cholesterol (TC) is important for cardiovascular disease risk management. The US Centers for Disease Control and Prevention (CDC) and Cholesterol Reference Method Laboratory Network (CRMLN) perform Abell-Levy-Brodie-Kendall (AK) reference measurement procedure (RMP) for TC as a secondary reference method, and implement Certification Protocol for Manufacturers. Japanese CRMLN laboratory at Osaka performed the AK RMP for 22 years, and conducted TC certification for reagent/calibrator/instrument systems of six Japanese manufacturers every 2 years for 16 years. Osaka TC performance was examined and compared to CDC's reference values. METHODS: AK RMP involved sample hydrolysis, cholesterol extraction, and determination of cholesterol levels by spectrophotometry. The Certification Protocol for Manufacturers includes comparison with AK RMP using at least 40 fresh specimens. Demonstration of average bias ≤3% and total coefficient of variation ≤3% qualified an analytical system for certification. RESULTS: In the AK RMP used in the Osaka CRMLN laboratory, the regression equation for measuring TC was y (Osaka)=1.000x (CDC)+0.032 (n=619, R2=1.000). Six Japanese manufacturers had allowable performance for certification. CONCLUSIONS: The AK RMP for TC measurement was accurate, precise, and stable for 22 years. Six Japanese manufacturers were certified for 16years. |

Nakamura M , Kayamori Y , Iso H , Kitamura A , Kiyama M , Koyama I , Nishimura K , Nakai M , Noda H , Dasti M , Vesper HW , Miyamoto Y . Clin Chim Acta 2014 431 288-93 BACKGROUND: Accurate measurement of blood lipids is crucial in cardiovascular disease risk management. The Centers for Disease Control and Prevention (CDC) Cholesterol Reference Method Laboratory Network (CRMLN) has assured the accuracy of these measurements for >20 y using beta quantification (BQ) method as reference measurement procedure (RMP) for high- and low-density lipoprotein cholesterol (HDL-C, LDL-C). Only limited data exist about the performance of the BQ RMP. METHODS: Bottom fraction cholesterol (BFC), HDL-C, and LDL-C results after ultracentrifugation from the CDC lipid reference laboratory and the Japanese CRMLN laboratory were compared using 280 serum samples measured over the past 15 y. Data were compared statistically using method comparison and bias estimation analysis. RESULTS: Regression analysis between CDC (x) and Osaka (y) for BFC, HDL-C, and LDL-C were y=0.988x+1.794 (R2=0.997), y=0.980x+1.118 (R2=0.994), and y=0.987x+1.200 (R2=0.997), respectively. The Osaka laboratory met performance goals for 90% to 95% of the CDC reference values. CONCLUSIONS: The BQ method by the Osaka CRMLN laboratory is highly accurate and has been stable for over 15 years. Accurate measurement of BFC is critical for determination of LDL-C. |
State indoor tanning laws and adolescent indoor tanning
Guy GP Jr , Berkowitz Z , Jones SE , O'Malley Olsen E , Miyamoto JN , Michael SL , Saraiya M . Am J Public Health 2014 104 (4) e69-74 OBJECTIVES: Recently, several state indoor tanning laws, including age restrictions, were promulgated to reduce indoor tanning among minors. We examined the effects of these laws on adolescent indoor tanning. METHODS: We used nationally representative data from the 2009 and 2011 national Youth Risk Behavior Surveys (n = 31 835). Using multivariable logistic regression, we examined the association between state indoor tanning laws and indoor tanning among US high school students. RESULTS: Female students in states with indoor tanning laws were less likely to engage in indoor tanning than those in states without any laws. We observed a stronger association among female students in states with systems access, parental permission, and age restriction laws than among those in states without any laws. We found no significant association among female students in states with only systems access and parental permission laws or among male students. CONCLUSIONS: Indoor tanning laws, particularly those including age restrictions, may be effective in reducing indoor tanning among female high school students, for whom rates are the highest. Such reductions have the potential to reduce the health and economic burden of skin cancer. |
Trends in sunscreen use among U.S. high school students: 1999-2009
Jones SE , Saraiya M , Miyamoto J , Berkowitz Z . J Adolesc Health 2012 50 (3) 304-7 PURPOSE: To examine trends in sunscreen use during 1999-2009 among U.S. high school students. METHODS: Data from the 1999-2009 national Youth Risk Behavior Surveys were analyzed. The surveys used a three-stage cluster sample design to produce nationally representative samples of students in grades 9-12 attending public and private schools. Student participation in the survey was anonymous and voluntary. Participants completed a self-administered questionnaire during a regular class period. The overall response rates ranged from 63% to 72%. RESULTS: During 1999-2009, the percentage of white students who never or rarely wore sunscreen when outside on a sunny day for >1 hour increased (from 57.5% to 69.4%), as did the percentage among Hispanic students (from 71.6% to 77.9%). This increase was most pronounced among white female students. The percentage of white and Hispanic students who most of the time or always wore sunscreen decreased during this same period. Rates of sunscreen use did not change among black students. CONCLUSIONS: Because of declines in sunscreen use, professionals in clinical, school, and community settings should emphasize the important role sunscreen may play in preventing skin cancer. |
Indoor tanning device use among male high school students in the United States
Miyamoto J , Berkowitz Z , Jones SE , Saraiya M . J Adolesc Health 2012 50 (3) 308-10 PURPOSE: Indoor tanning is a risk factor for developing melanoma. Although in 2009, 6.7% of male high school students reported using an indoor tanning device, compared with 25.4% of female students (Eaton DK, Kann L, Kinchen S, et al, MMWR Surveill Summ 2010;59:1-142), it is also less well characterized in male than in female adolescents. METHODS: The associations between appearance-related and other health-related behaviors with indoor tanning device use were examined among male high school students in the United States, using the 2009 National Youth Risk Behavior Survey. RESULTS: Adjusted analysis of cross-sectional data showed that indoor tanning device use was positively associated with ever having taken steroids without a doctor's prescription, unhealthy weight control practices, binge drinking, eating fruits and vegetables five or more times per day, playing on at least one sports team, and attempted suicide. CONCLUSIONS: Understanding the relationship between indoor tanning device use and appearance-related and other health-related behaviors is useful in designing risk reduction interventions for skin cancer prevention. |
