RESUMO

BACKGROUND: Given the disproportionately elevated anal cancer risk in high-risk populations, it is important to assess the performance of commonly used anal cancer screening tools to improve the effectiveness of detection and treatment methods. This study evaluates 1) the concordance between anal cytology and histology results and 2) the performance of cytology and high-risk human papillomavirus (HR-HPV) genotyping as screening tools for detecting histologically confirmed anal high-grade squamous intraepithelial lesions (HSIL). METHODS: Data from the Anal Neoplasia Clinic in Puerto Rico (2014-2021; n = 466) was used. The clinical performance of anal cytology and HR-HPV genotyping to detect HSIL was compared to the gold standard: high-resolution anoscopy-guided biopsy. Sensitivity, specificity, positive predictive value, negative predictive value, and κ coefficients were calculated. RESULTS: A total of 66.95% of the patients were men, 74.0% were people living with HIV, 76.2% had anal HR-HPV infection, and 40.34% had histologically confirmed anal HSIL. The weighted κ statistic between the tests (cytology and histology) was 0.25 (p < .001). The sensitivity and specificity of cytology alone to detect anal HSIL were 84.3% (95% confidence interval [CI], 78.3%-89.1%) and 36.0% (95% CI, 30.3%-42.0%), respectively. Anal HR-HPV genotyping had higher sensitivity (92.2%; 95% CI, 87.4%-95.6%) and similar specificity (34.8%; 95% CI, 29.2%-40.7%) compared to cytology. The two tests combined (positive results following cytology or HR-HPV test) improved sensitivity to detect anal HSIL (97.9%; 95% CI, 94.8%-99.4%), but specificity was compromised (19.2%; 95% CI, 14.7%-24.4%). CONCLUSION: Although HR-HPV genotyping improved the detection of anal HSIL, HR-HPV testing had lower specificity than anal cytology alone.

RESUMO

BACKGROUND: Acute lymphoblastic leukemia (ALL) accounts for 80% of all leukemias diagnosed in children. Although ALL age patterns are consistent across racial/ethnic groups, their incidence and mortality rates are highly variable. We assessed the age-standardized ALL incidence and mortality rates of Puerto Rican Hispanic (PRH) children and compared them with those of US mainland Hispanics (USH), non-Hispanic Whites (NHW), non-Hispanic Blacks (NHB), and Non-Hispanic Asian or Pacific Islanders (NHAPI). METHODS: Differences between racial/ethnic groups were assessed by estimating the standardized rate ratio (SRR) for 2010 to 2014. Secondary data analyses of the Puerto Rico Central Cancer Registry and the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) databases were performed for the 2001 to 2016 period. RESULTS: PRH children had 31% lower incidence rates than USH, but 86% higher incidence rates than NHB. In addition, the incidence trends of ALL increased significantly from 2001 to 2016 among PRH and USH, with 5% and 0.9% per year, respectively. Moreover, PRH have a lower 5-year overall survival (81.7%) when compared with other racial/ethnic groups. CONCLUSIONS: PRH children were found to have disparities in ALL incidence and mortality rates compared with other racial/ethnic groups in the US. Additional research is warranted to identify the genetic and environmental risk factors that may be associated with the disparities observed. IMPACT: This is the first study reporting the incidence and mortality rates of childhood ALL for PRH and making comparisons with other racial/ethnic groups in the US.

RESUMO

Prior to the COVID pandemic, Puerto Rico (PR) had one of the highest Human Papillomavirus (HPV) vaccine rates in the United States. The COVID pandemic and administration of COVID vaccines might have impacted attitudes toward HPV vaccination. This study compared attitudes toward HPV and COVID vaccines with respect to school-entry policies among adults living in PR. A convenience sample of 222 adults (≥21 years old) completed an online survey from November 2021 to January 2022. Participants answered questions about HPV and COVID vaccines, attitudes toward vaccination policies for school-entry, and perceptions of sources of information. We assessed the magnitude of association between the agreement of school-entry policies for COVID and HPV vaccination by estimating the prevalence ratio (PRadjusted) with 95% Confidence Intervals (95% CI). The most trusted source of information for HPV and COVID vaccines were healthcare providers (42% and 17%, respectively) and the CDC (35% and 55%, respectively), while the least trusted were social media (40% and 39%, respectively), and friends and family (23% n = 47, and 17% n = 33, respectively). Most participants agreed that HPV (76% n = 156) and COVID vaccines (69% n = 136) should be a school-entry requirement. Agreement with school policy requiring COVID vaccination was significantly associated with agreement of school policy requiring HPV vaccination (PRadjusted:1.96; 95% CI:1.48-2.61) after controlling for potential confounders. Adults living in PR have an overall positive attitude about mandatory HPV and COVID vaccination school-entry policies, which are interrelated. Further research should elucidate the implications of the COVID pandemic on HPV vaccine attitudes and adherence rates.

RESUMO

Background: Persons living with HIV (PLWH) are at high risk of developing anal high-grade squamous intraepithelial lesions (HSIL). We aimed to develop a prediction model for anal HSIL based on individual characteristics of PLWH. Methods: Cross-sectional study of PLWH aged ≥21 years who attended the Anal Neoplasia Clinic of the University of Puerto Rico Comprehensive Cancer Center from 2016 to 2022. The primary outcome was biopsy-confirmed anal HSIL. For each sex, relations between potential predictors and HSIL were examined using univariate (ULRM) and multivariable (MLRM) logistic regression models. Risk modelling was performed with MLRM and validated with bootstrapping techniques. The area under the ROC Curves (AUC) was estimated with 95% CI. Findings: HSIL was detected among 45.11% of patients, 68.48% were males, and 59.42% were ≥45 aged. Multivariable analysis showed that, in women, the only significant predictor for HSIL was having a previous abnormal anal cytology (p = 0.01). In men, significant predictors for HSIL were having a previous abnormal anal cytology (p < 0.001) and a history of infection with any gonorrhoea (p = 0.002). Other suggestive predictors for HSIL among women were obesity and smoking. No association between smoking and HSIL among men was observed (p < 0.05). The AUC estimated among women (0.732, 95% CI: 0.651-0.811) was higher than in men (0.689, 95% CI: 0.629-0.748). Interpretation: Our results support that the inclusion of individual characteristics into the prediction model will adequately predict the presence of HSIL in PLWH. Funding: This work was supported by the NCI (Grants #U54CA096297, #R25CA240120), the NIGMS (Grant #U54GM133807), and the NIMHD (Grant #U54MD007587).

RESUMO

In September 2017, Hurricane Maria devastated the Caribbean region, among them the US territory of Puerto Rico (PR). Vaccination distribution and uptake suffered from the impact. This study evaluated the trends in monthly vaccination initiation rates for human papilloma virus (HPV), Tdap and meningococcal conjugate (MenACWY) adolescent vaccines from 2015 to 2019, during which it was possible to observe and analyze the impact of Hurricane Maria on vaccine initiation. Monthly initiation rates were estimated. Age-standardized initiation rate ratio (SRR) and 95% CI were estimated. The analysis included 85,340 adolescents; 52.3% were male, and 47.7% were females. September 2017 showed HPV vaccine initiation had the lower rates of all the studied vaccines, with a rate of 75% after the disaster (from a rate of almost 90% in July 2017). Tdap and MenACWY vaccines rates remained above 90% in the same period. The SRR of HPV vaccine for September and October 2017 showed an estimated reduction of 5% and 8% in vaccine initiation rates, respectively for each month, when 2016 was the reference year (p > .05). The SRR of Tdap and MenACWY vaccines for November 2017 showed significant reductions when 2015 and 2016 were reference years (p < .05). HPV vaccine initiation rate was the most severely affected by the Hurricane Maria. Post-natural disaster protocols should strengthen existing programs for facilitate immunization access.

RESUMO

In 2018, Puerto Rico (PR) enacted a Human papillomavirus (HPV) vaccine school-entry requirement for students ages 11 to 12. Using the Consolidated Framework for Implementation Research (CFIR), we aimed to identify potential barriers and facilitators of this implementation. We conducted 38 qualitative interviews with stakeholders in PR from different organizations (Department of Health, Schools, Healthcare Providers, and Community organizations). We evaluated construct rating variability between the organizations to determine barriers and facilitators. The strongest facilitator determined was stakeholder's awareness of the parent's and student's needs to meet the HPV school-entry requirement. Other facilitators included initiatives for school-entry policies and the relative advantage of this requirement over different strategies. The strongest barriers included was the cost for private providers to administer the HPV vaccine, the negative influence of social media about the vaccine, which affected parents' acceptance, and the lack of school nurses as available staff resources for the school entry requirement. Findings from this study can be used to improve implementation (adaptations/modifications) and inform other states and countries in earlier stages of consideration of the adoption of similar immunization policies. Most barriers can be modifiable with the implementation of educational programs/training across schools, considering that they are the first line of response to parents of this school entry requirement.

RESUMO

BACKGROUND: Hurricane Maria struck Puerto Rico on Sept 20, 2017, devastating the island. Controversy surrounded the official death toll, fuelled by estimates of excess mortality from academics and investigative journalists. We analysed all-cause excess mortality following the storm. METHODS: We did a time-series analysis in Puerto Rico from September, 2017, to February, 2018. Mortality data were from the Puerto Rico Vital Statistics System. We developed two counterfactual scenarios to establish the population at risk. In the first scenario, the island's population was assumed to track the most recent census estimates. In the second scenario, we accounted for the large-scale population displacement. Expected mortality was projected for each scenario through over-dispersed log-linear regression from July, 2010, to August, 2017, taking into account changing distributions of age, sex, and municipal socioeconomic development, as well as both long-term and seasonal trends in mortality. Excess mortality was calculated as the difference between observed and expected deaths. FINDINGS: Between September, 2017, and February, 2018, we estimated that 1191 excess deaths (95% CI 836-1544) occurred under the census scenario. Under the preferred displacement scenario, we estimated that 2975 excess deaths (95% CI 2658-3290) occurred during the same observation period. The ratio of observed to expected mortality was highest for individuals living in municipalities with the lowest socioeconomic development (1·43, 95% CI 1·39-1·46), and for men aged 65 years or older (1·33, 95% CI 1·30-1·37). Excess risk persisted in these groups throughout the observation period. INTERPRETATION: Analysis of all-cause mortality with vital registration data allows for unbiased estimation of the impact of disasters associated with natural hazards and is useful for public health surveillance. It does not depend on certified cause of death, the basis for the official death toll in Puerto Rico. Although all sectors of Puerto Rican society were affected, recovery varied by municipal socioeconomic development and age groups. This finding calls for equitable disaster preparedness and response to protect vulnerable populations in disasters.

RESUMO

OBJECTIVE: To determine the mean levels of glycated hemoglobin (HbA1c) in a subsample of non-diabetic Hispanic Puerto Ricans living in the San Juan metropolitan area (SJMA) and to assess the sensitivity and specificity of HbA1c as a diagnostic test for prediabetes. RESEARCH DESIGN AND METHODS: This was a secondary data analysis of the parent study, Burden of Diabetes and Hypertension in the Adult Population of the San Juan Metropolitan Area of Puerto Rico. Based on their HbA1c and fasting plasma glucose (FPG) values, 370 adults (147 males; 223 females) were classified as non-diabetics. An additional analysis of sensitivity, specificity, and predictive values for this subsample examined the association between FPG and HbA1c. RESULTS: The mean HbA1c among the non-diabetic population was 5.38% (±0.23). Sensitivity, specificity, and the area under the receiving operating characteristic curve were 56.8%, 74.2%, and 84.3%, respectively, for the diagnosis of prediabetes, using HbA1c as the sole diagnostic test (P<0.001). CONCLUSION: This study demonstrated that HbA1c levels among the non-diabetic Hispanic population residing in the SJMA were very similar to those of non-Hispanic whites living in the US. Our results are consistent with those of other studies that have shown that the sensitivity of the HbA1c test is too low to be used in the diagnosis of prediabetes.

RESUMO

OBJECTIVE: The aim of the study was to estimate the magnitude of the association between HPV-related gynecological neoplasms and secondary anal cancer among women in Puerto Rico (PR). MATERIALS AND METHODS: We identified 9,489 women who had been diagnosed with a primary cervical, vaginal, or vulvar tumor during 1987-2013. To describe the trends of invasive cervical, vulvar, vaginal, and anal cancer, the age-adjusted incidence rates were estimated using the direct method (2000 US as Standard Population). Standardized incidence ratios (observed/expected) were computed using the indirect method; expected cases were calculated using 2 methods based on age-specific rates of anal cancer in PR. The ratio of standardized incidence ratios of anal cancer was estimated using the Poisson regression model to estimate the magnitude of the association between HPV-gynecologic neoplasms and secondary anal cancer. RESULTS: A significant increase in the incidence trend for anal cancer was observed from 1987 to 2013 (annual percent change = 1.1, p < .05), whereas from 2004 to 2013, an increase was observed for cervical cancer incidence (annual percent change = 3.3, p < .05). The risk of secondary anal cancer among women with HPV-related gynecological cancers was approximately 3 times this risk among women with non-HPV-related gynecological cancers (relative risk = 3.27, 95% CI = 1.37 to 7.79). CONCLUSIONS: Anal cancer is increasing among women in PR. Women with gynecological HPV-related tumors are at higher risk of secondary anal cancer as compared with women from the general population and with those with non-HPV-related gynecological cancers. Appropriate anal cancer screening guidelines for high-risk populations are needed, including women with HPV-related gynecological malignancies and potentially other cancer survivors.

RESUMO

OBJECTIVE: It is unknown if human papillomavirus (HPV) serum antibody responses vary by anatomic site of infection. We aimed to assess the seroprevalence for HPV 6, 11, 16 and 18 in association with HPV DNA detection in different anatomic sites among women. METHODS: This cross sectional population-based study analyzed data from 524 women aged 16-64 years living in the San Juan metropolitan area of Puerto Rico (PR). Questionnaires were used to assess demographic and lifestyle variables, while anogenital and blood samples were collected for HPV analysis. Logistic regression models were used to estimate the adjusted prevalence odds ratio (POR) in order to determine the association between HPV DNA infection status in the cervix and anus and serum antibody status, controlling for different potential confounders. RESULTS: Overall, 46.9% of women had detectable antibodies to one or more types whereas 8.7% had HPV DNA for one or more of these types detected in cervix (4.0%) or anus (6.5%). Women with cervical HPV detection tended to be more HPV seropositive than women without cervical detection (adjusted POR (95%CI): 2.41 (0.90, 6.47), p=0.078); however the type-specific association between cervical DNA and serum antibodies was only significant for HPV 18 (adjusted POR (95% CI): 5.9 (1.03, 33.98)). No significant association was detected between anal HPV and seropositivity (p>0.10). CONCLUSION: Differences in the anatomic site of infection could influence seroconversion, however, longitudinal studies will be required for further evaluation. This information will be instrumental in advancing knowledge of immune mechanisms involved in anatomic site response.

RESUMO

Breast cancer (BC) is a heterogeneous disease which many studies have classified in at least four molecular subtypes: Luminal A, Luminal B, HER2-Enriched, and Basal-like (including triple-negative breast cancer, TNBC). These subtypes provide information to stratify patients for better prognostic predictions and treatment selection. Individuals vary in their sensitivities to carcinogens due to differences in their DNA repair capacity (DRC) levels. Although our previous case-control study established low DRC (in terms of NER pathway) as a BC risk factor, we aim to study this effect among the molecular subtypes. Therefore, the objectives of this study include investigating whether DRC varies among molecular subtypes and testing any association regarding DRC. This study comprised 267 recently diagnosed women with BC (cases) and 682 without BC (controls). Our results show a substantial variability in DRC among the molecular subtypes, with TNBC cases (n = 47) having the lowest DRC (p-value < 0.05). Almost 80 percent of BC cases had a DRC below the median (4.3%). Low DRC was strongly associated with the TNBC subtype (OR 7.2; 95% CI 3.3, 15.7). In conclusion, our study provides the first report on the variability among the molecular subtypes and provides a hypothesis based on DRC levels for the poor prognosis of TNBC.

RESUMO

OBJECTIVE: Describe the trend of the indirect standardized death rate of HIV for different modes of HIV transmission from 2003 to 2014 in Puerto Rico. Estimate the magnitude of the association between mode of HIV transmission and mortality at different time periods in Puerto Rico. METHODS: ISDRs by sex and mode of transmission were computed using data from the PR National HIV/AIDS Surveillance System (2003-2014). Poisson models were used to assess the annual percent change of the ISDRs and RRs by sex. RESULTS: Injection drug users (IDUs) showed the highest decrease in ISDR (-10.56, for men; -9.32 for women). Compared to men who have sex with men (MSM), IDU men also had the highest RR, representing an increase of 93% (2009-2011) (RRIDU vs MSM: 1.93, 95% CI: 1.66-2.23). Compared to women who were IDUs, heterosexual (HET) women had less risk of dying (48% for the period of 2006 to 2008). CONCLUSION: Mortality has been decreasing in each mode of transmission for both sexes. In addition, though IDUs present the highest decrease of ISDR, it is still the group whose members have the highest risk of dying, both men and women. To better describe health disparities as related to HIV/AIDS mortality, future analyses should be performed using specific causes of death and the evaluation of other relevant clinical and sociodemographic factors. Such data might increase our understanding of mortality in people with HIV/AIDS on the island, as well as help in future efforts to develop intervention strategies for the aforementioned risk groups.

RESUMO

OBJECTIVE: The incidence of oral cavity and pharyngeal cancer in Puerto Rican men is higher than it is in the men of any other ethnic/racial group in the United States of America (US). The information regarding the effect of the human papilloma virus (HPV) in the gene-expression profile among patients with this cancer is limited in Hispanic community. We aim to describe the methodology for future studies to identify the molecular networks for determining overrepresented signaling and metabolic canonical pathways, based on the differential gene-expression profiles of HPV+ and HPV- samples from patients with oropharyngeal squamous cell carcinoma in Puerto Rico. METHODS: We analyzed the RNA expression of 5 tissue samples from subjects diagnosed with oropharyngeal squamous cell carcinoma, 2 HPV+ and 3 HPV-, using Affymetrix GeneChips. The relative difference between the average gene expressions of the HPV+ and HPV- samples was assessed, based on the fold change (log2-scale). RESULTS: Our analysis revealed 10 up regulated molecules (Mup1, LRP1, P14KA, ALYREF, and BHMT) and 5 down regulated ones (PSME4, KEAP1, ELK3, FAM186B, and PRELID1), at a cutoff of 1.5-fold change. Ingenuity Pathway Analysis showed the following biological functions to be affected in the HPV+ samples: cancer, hematological disease, and RNA post-transcriptional modification. QRT-PCR analysis confirmed only the differential regulation of ALYREF, KEAP1, and FAM186B genes. CONCLUSION: The relevant methodological procedures described are sufficient to detect the most significant biological functions and pathways according to the HPV status in patients with oropharyngeal cancer in Puerto Rico.

RESUMO

This secondary data analysis aimed to estimate the prevalence of same-sex behavior and sexual and health-related practices of a population-based sample (n=560) of women aged 16-64 years in Puerto Rico (PR). Data collection included interviews and biologic samples. Seven percent of the sample had had sex with other women (WSW). Age-adjusted logistic regression models indicated that WSW had higher odds of history of cancer, having ≥ 7 lifetime sexual partners, using sex toys and sharing them, and use of tobacco and illicit drugs. Future research is needed to address the health needs of WSW, including cancer-related risk factors and sexual practices.

RESUMO

PURPOSE: Drug abuse is a major risk factor in the development and progression of HIV-1. This study defines the alterations in the plasma proteome of HIV-1-infected women that use cocaine. EXPERIMENTAL DESIGN: Plasma samples from 12 HIV-seropositive Hispanic women under antiretroviral therapy were selected for this study. Six sample pairs were matched between nondrug users and cocaine users. After IgG and albumin depletion, SDS-PAGE, and in-gel digestion, peptides from nondrug users and cocaine users were labeled with (16) O and (18) O, respectively, and subjected to LC-MS/MS and quantitation using Proteome Discover and QuiXoT softwares and validated by ELISA. RESULTS: A total of 1015 proteins were identified at 1% false discovery rates (FDR). Statistical analyses revealed 13 proteins with significant changes between the two groups, cocaine and noncocaine users (p < 0.05). The great majority pertained to protection defense function and the rest pertained to transport, homeostatic, regulation, and binding of ligands. Apolipoprotein CIII was increased in plasma of HIV+ Hispanic women positive for cocaine compared to HIV+ nondrug users (p ≤ 0.05). CONCLUSIONS AND CLINICAL RELEVANCE: Increased human apolipoprotein CIII warrants that these patients be carefully monitored to avoid the increased risk of cardiovascular events associated with HIV, HAART, and cocaine use.

RESUMO

This article describes the methodology of the first population-based study of human papillomavirus (HPV) infection among women aged 16-64 years residing in the San Juan Metropolitan Area of Puerto Rico (PR). The sample was identified through a complex sampling design of households. The sampling frame was selected in four stages, using census tracts maps from the Census Bureau. Women completed a face-to-face interview and a computer-assisted self-interview using the Audio CASI system, for the collection of demographic, clinical, and lifestyle variables, and sampling acceptability. Anal, cervical, and oral specimens were collected through self-collection methods for HPV DNA testing using a modified pool of MY09/MY11 consensus HPV L1 and human ß-globin amplification primers. Anthropometric measurements were taken using the Third National Health and Nutrition Examination Survey methodology. Blood samples were collected to create a bio-repository for future HPV-related studies. Fifty census tract blocks were randomly selected. We recruited 566 women, with a response rate of 83.4%. Response rates did not vary by age-group (p>0.05); although they varied by socioeconomic (SES) census block stratums (p<0.05), response rates were good (>75%) in all SES strata. All participants agreed to respond to the surveys and provide the requested anogenital and oral samples. Overall, more than 98% understood and more than 50% felt comfortable with the cervical, anal, and oral self-collection methods used. This article documents the feasibility of performing population-based studies for HPV surveillance in women in PR.

RESUMO

OBJECTIVE: To assess the prevalence of cervical cancer screening through Papanicolaou (Pap) test utilization and its association with sexual behaviors among a population-based sample of Hispanic women in Puerto Rico (PR). METHODS: This study was a secondary data analysis of the database of a cross-sectional study of HPV infection in PR (2010-2013; n = 554 women). Pap test utilization (past 3 years) was self-reported and sexual risky behavior was defined as an index that considered the following sexual behaviors: early age of sexual debut (≤16 years), 11 or more lifetime sexual partners, and 2 or more sexual partners in the last year. Multivariable logistic regression was used to estimate the magnitude of the association between sexual risk behavior and Pap test utilization, after adjusting for socioeconomic and lifestyles characteristics. RESULTS: The overall prevalence of Pap test utilization was 78.0%. Pap test screening varied with sexual behavior, with women with none or one risky sexual behavior having higher odds of Pap test utilization in the past 3 years (odds ratio [OR], 1.74; 95% CI, 1.03-2.93) compared with those with two or three risky sexual behaviors. This difference remained marginally significant (p < .10) after adjusting for age, educational attainment, smoking status and STI history (OR, 1.72; 95% CI, 0.96-3.08). CONCLUSIONS: The prevalence of cervical cancer screening in this population (78%) is still below Healthy People 2020 recommendations (93%). Also, women with risky sexual behaviors are less likely to have been screened. Efforts to promote cervical screening programs should focus on these high-risk women as a method for cervical cancer prevention and control.

RESUMO

This study compared the incidence of lung cancer among Puerto Ricans (PRs) with that of Whites, Blacks, and Hispanics in the United States. We computed age-standardized rates of lung cancer during 1992-2010 and percentages of change over time. Standardized rate ratios (SRR) were estimated to assess racial/ethnic and gender differences. All men groups showed a significant decline in lung cancer over time but PRs observed the smallest change (-1.2%). For both men and women, PRs had lower incidence rates compared to other racial/ethnic groups (SRR < 1; P < 0.05). Among all groups, men reported higher incidence rates than women but PRs showed the largest gender disparity (SRR = 2.29). This study showed that although PRs exhibited lower incidence rates of lung cancer, this subgroup of Hispanics faced an important burden of lung cancer, principally because PR men had the smallest decline over time and the largest gender difference among all groups.

RESUMO

This study examined the prevalence and association of diabetes mellitus (DM) and prediabetes with cardiovascular risk factors among Puerto Ricans adults. Data from a household survey of 857 adults aged 21-79 years who underwent interviews, physical exams, and blood draws were analyzed. Prevalence of total DM and prediabetes was estimated using American Diabetes Association diagnostic criteria of fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c). Poisson regression models were used to estimate the prevalence ratio for each cardiovascular risk factor under study. Age-standardized prevalence of total DM and prediabetes, detected by FPG and/or HbA1c, was 25.5 and 47.4 %, respectively. Compared with participants with normoglycemia, those with previously diagnosed DM, undiagnosed DM, and prediabetes had more adverse cardiovascular risk factor profiles, characterized by a higher prevalence of general and abdominal obesity, hypertension, low HDL cholesterol, elevated LDL cholesterol, elevated triglycerides, and elevated plasminogen activator inhibitor 1 (p < 0.05). The high prevalence of DM and prediabetes calls for public health actions to plan and implement lifestyle interventions to prevent or delay the onset of DM and cardiovascular disease.
