Self-reported Use of Eye Care Among Adult Chinese Americans: The Chinese American Eye Study.

ABSTRACT: To identify the prevalence and determinants of self-reported eye care use among Chinese Americans.Population-based, cross-sectional study.A total of 4582 Chinese Americans 50 years and older residing in Monterey Park, California.Multivariable logistic regression analyses based on Andersen's Behavioral Model of Health Services Use were conducted to identify predisposing, enabling, and need variables associated with self-reported eye care use.Prevalence of self-reported use assessed as eye care visit in the past 12 months, dilated eye examination in the past 12 months, and ever having had a dilated examination, and odds ratios for factors associated with these measures.Overall, 36% of participants reported an eye care visit and 21% reported a dilated examination in the past 12 months. Forty-eight percent reported ever having had a dilated eye examination. Older age, female sex, preference for English, more education, health and vision insurance, a usual place for health care, currently driving, a greater number of comorbidities, and lower vision-specific quality-of-life (NEI VFQ-25) scores were associated with higher odds of reporting use of eye care.Use of eye care among Chinese Americans was found to be as low as what is reported for African Americans and Hispanics, and lower than what is reported for whites. Multiple modifiable factors are associated with use of eye care among the rapidly growing Chinese American population. Culturally sensitive interventions targeting these factors should be a priority. Further research is needed to investigate how findings from this group of Chinese Americans reflect other Asian Americans that are different in language and ethnicity.

Project description:ObjectiveTo identify factors associated with prevalent diabetic retinopathy (DR) among Chinese American adults with type 2 diabetes mellitus (T2DM), and to compare these factors to ones previously described for a population-based sample of Latinos with a higher DR prevalence.DesignPopulation-based cross-sectional study.Participants4582 Chinese Americans aged 50 or older residing in Monterey Park, California.MethodsParticipants completed an in-home questionnaire on socio-demographic status and medical history, and a comprehensive clinical eye examination, using the same protocol implemented in the Los Angeles Latino Eye Study. Fundus photographs from 7 Early Treatment Diabetic Retinopathy fields were graded in a masked manner using a modified Airlie House grading system to assess presence and severity of DR. Logistic regression analyses based on a conceptual model of DR risk identified factors associated with prevalent DR.Main outcome measuresOdds ratios (ORs) and 95% confidence intervals (CIs) for factors associated with DR and vision-threatening DR (VTDR).ResultsIn total, 238 participants were diagnosed with any DR; 27 of these were classified as having VTDR. Both, any DR and VTDR showed statistically significant positive associations with T2DM duration (OR5-9 years = 1.24, OR10-14 years = 2.07, OR15+years = 3.99), glycosylated hemoglobin (HbA1c) (OR6.5-6.9% = 1.33, OR7-7.9% = 1.86, OR8%+ = 3.22), systolic blood pressure (SBP) (ORper 10mmHg+ = 1.19), and insulin treatment (ORinsulin+ = 2.44). For VTDR, we also found novel associations with antihypertensive drugs (OR: 0.18; 95% CI: 0.06-0.61) and statins (OR: 4.96; 95% CI: 1.60-16.41). Chinese Americans and Latinos had a nearly identical DR probability based on HbA1c and SBP. However, Latinos had a higher DR probability at every year of duration of T2DM (≥ 5 years).ConclusionsWhile we observed an overall lower DR prevalence in Chinese Americans than in Latinos (35.8% of individuals with TD2M in Chinese Americans versus 42.0% in Latinos), our data indicate that the impact of increasing HbA1c and SBP on DR probability is incrementally the same in both populations. However, increasing T2DM duration is associated with higher DR probability in Latinos than Chinese Americans, even after controlling for other known predictors. Novel factors associated with VTDR include antihypertensive drugs and statins. However, to determine if these drugs impact VTDR susceptibility, we need longitudinal data and more cases.

Project description:PurposeWe sought to investigate anatomic mechanisms of angle narrowing by assessing ocular biometric determinants of anterior chamber angle width.DesignPopulation-based cross-sectional study.MethodsSubjects ≥50 years of age from the Chinese American Eye Study underwent a comprehensive ocular examination, including anterior segment optical coherence tomography imaging and ultrasound A-scan. Independent variables, including anterior chamber depth (ACD), lens vault (LV), iris curvature (IC), anterior chamber width, lens thickness, vitreous cavity depth, and axial length, and dependent variables, including angle opening distance, were measured in 1 randomly selected eye per subject. Univariable and multivariable regression models with standardized regression coefficients (SRCs) and semipartial correlation coefficients squares (SPCC2) were used to assess relative and unique contributions by independent variables to angle width.ResultsTwo thousand two hundred twenty-five subjects (1433 women and 834 men) were included in the analysis. All biometric parameters except lens thickness differed between men and women (age-adjusted P < .001). In model 1A (R2 = 0.66), which included ACD, lens thickness, and vitreous cavity depth, ACD (SRC = 0.64, SPCC2 = 0.19) and IC (SRC = -0.26, SPCC2 = 0.041) were the strongest determinants of angle opening distance. In model 1B (R2 = 0.58), which included LV and axial length, LV (SRC = -0.46, SPCC2 = 0.1) and IC (SRC = -0.3, SPCC2 = 0.047) were the strongest determinants of angle opening distance. Determinants of angle width were similar in separate multivariable models for men and women.ConclusionsACD, LV, and IC are the strongest determinants of angle width in Chinese Americans. Sex-related differences in angle width are explained by differences among biometric measurements. These results provide insights into anatomic mechanisms of angle narrowing and have important implications for quantitative assessments of angle closure eyes.

Project description:Importance:Contemporary data on use of eye care by US adults are critical, as the prevalence of age-related eye disease and vision impairment are projected to increase in the coming decades. Objectives:To provide nationally representative estimates on self-reported use of eye care by adults aged 50 to 80 years, and to describe the reasons that adults do and do not seek eye care. Design, Setting, and Participants:The National Poll on Healthy Aging, a cross-sectional, nationally representative online survey was conducted from March 9 to 24, 2018, among 2013 individuals aged 50 to 80 years. Main Outcomes and Measures:The proportion of US adults who received an eye examination within the past 2 years as well as the sociodemographic and economic factors associated with receipt of eye care. Results:Among 2013 adults aged 50 to 80 years (survey-weighted proportion of women, 52.5%; white non-Hispanic, 71.1%; mean [SD] age, 62.1 [9.0] years), the proportion reporting that they underwent an eye examination in the past year was 58.5% (95% CI, 56.1%-60.8%) and in the past 2 years was 82.4% (95% CI, 80.4%-84.2%). Among those with diabetes, 72.2% (95% CI, 67.2%-76.8%) reported undergoing an eye examination in the past year and 91.3% (95% CI, 87.7%-93.9%) in the past 2 years. The odds of having undergone an eye examination within the past 2 years were higher among women (adjusted odds ratio [AOR], 2.00; 95% CI, 1.50-2.67), respondents with household incomes of $30?000 or more (AOR, 1.57; 95% CI, 1.08-2.29), and those with a diagnosed age-related eye disease (AOR, 3.67; 95% CI, 2.37-5.69) or diabetes (AOR, 2.30; 95% CI, 1.50-3.54). The odds were lower for respondents who were unmarried (AOR, 0.71; 95% CI, 0.53-0.96), from the Midwest (AOR, 0.55; 95% CI, 0.34-0.87) or West (AOR, 0.60; 95% CI, 0.38-0.94), or reported fair or poor vision (AOR, 0.43; 95% CI, 0.28-0.65). Reasons reported for not undergoing a recent eye examination included having no perceived problems with their eyes or vision (41.5%), cost (24.9%), or lack of insurance coverage (23.4%). Conclusions and Relevance:In this study, the rate of eye examinations was generally high among US adults aged 50 to 80 years, yet there were several significant demographic and socioeconomic differences in the use of eye care. These findings may be relevant to health policy efforts to address disparities in eye care and to promote care for those most at risk for vision problems.

Project description:BackgroundCritically ill patients with 2009 H1N1 influenza are often treated in intensive care units (ICUs), representing significant risk of nosocomial transmission to critical care clinicians and other patients. Despite a large body of literature and guidelines recommending infection control practices, numerous barriers have been identified in ICUs, leading to poor compliance to the use of personal protective equipment (PPE). The use of PPE among critical care clinicians has not been extensively evaluated, especially during the pandemic influenza. This study examined the knowledge, attitudes, and self-reported behaviors, and barriers to compliance with the use of PPE among ICU healthcare workers (HCWs) during the pandemic influenza.Methodology/principal findingsA survey instrument consisting of 36 questions was developed and mailed to all HCWs in 21 ICUs in 17 provinces in China. A total of 733 physicians, nurses, and other professionals were surveyed, and 650 (88.7%) were included in the analysis. Fifty-six percent of respondents reported having received training program of pandemic influenza before they cared for H1N1 patients, while 77% reported to have adequate knowledge of self and patient protection. Only 18% of respondents were able to correctly identify all components of PPE, and 55% reported high compliance (>80%) with PPE use during patient care. In multivariate analysis, vaccination for 2009 H1N1 influenza, positive attitudes towards PPE use, organizational factors such as availability of PPE in ICU, and patient information of influenza precautions, as well as reprimand for noncompliance by the supervisors were associated with high compliance, whereas negative attitudes towards PPE use and violation of PPE use were independent predictors of low compliance.Conclusion/significanceKnowledge and self-reported compliance to recommended PPE use among Chinese critical care clinicians is suboptimal. The perceived barriers should be addressed in order to close the significant gap between perception and knowledge or behavior.
