Sex Differences in HIV Testing - 20 PEPFAR-Supported Sub-Saharan African Countries, 2019.

Despite progress toward controlling the human immunodeficiency virus (HIV) epidemic, testing gaps remain, particularly among men and young persons in sub-Saharan Africa (1). This observational study used routinely collected programmatic data from 20 African countries reported to the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) from October 2018 to September 2019 to assess HIV testing coverage and case finding among adults (defined as persons aged ≥15 years). Indicators included number of HIV tests conducted, number of HIV-positive test results, and percentage positivity rate. Overall, the majority of countries reported higher HIV case finding among women than among men. However, a slightly higher percentage positivity was recorded among men (4.7%) than among women (4.1%). Provider-initiated counseling and testing (PITC) in health facilities identified approximately two thirds of all new cases, but index testing had the highest percentage positivity in all countries among both sexes. Yields from voluntary counseling and testing (VCT) and mobile testing varied by sex and by country. These findings highlight the need to identify and implement the most efficient strategies for HIV case finding in these countries to close coverage gaps. Strategies might need to be tailored for men who remain underrepresented in the majority of HIV testing programs.

Diagnoses and ordering practices driving blood demand for treatment of anemia in Tanzania.

BACKGROUND: Resource-limited countries in Africa experience blood shortages. Understanding clinical drivers of blood demand can inform strategies to increase blood availability. STUDY DESIGN AND METHODS: From a national representative sample of 42 hospitals in Tanzania, patient records and requests for whole blood (WB) and red blood cells (RBCs) to treat anemia were analyzed using data collected prospectively from June through September 2013. Abstracted data included cause of anemia, number of requested units, clinical signs, and pretransfusion hemoglobin (Hb) levels. Weighted projections of nationwide drivers of blood demand for the year, 2013, were calculated. Mean posttransfusion Hb levels were estimated, and blood requests were assessed for clinical appropriateness. RESULTS: Malaria was the leading driver of blood demand for anemia among children, accounting for 67% (55,949 units; standard deviation [SD], 1911 units) of projected units requested for children in 2013. Maternal hemorrhage was the leading driver of blood demand for anemia among adults, accounting for 21% (31,321 units; SD, 963 units) of projected units requested. Seventeen percent (26,133 units; SD, 1013 units) of projected requested units were deemed inappropriate. Adults with severe anemia had a mean Hb level of 3.7 g/dL and a mean of 1.6 WB or RBC units per request, resulting in an estimated mean posttransfusion Hb level of 5.3 g/dL. CONCLUSIONS: Strategies to prevent and treat underlying causes of anemia and decrease inappropriate blood requests will likely increase blood availability. Restrictive blood ordering practices seen in adults with severe anemia suggests undertreatment of anemia and may result in an underestimation of the national blood demand.

Estimated population size of the people who inject drugs in Thai Nguyen, Vietnam: A two survey capture-recapture study using respondent driven sampling.

To develop an appropriate programmatic response to the concentrated HIV epidemic, program managers require reliable estimates of the sizes of the key populations. This study attempts to estimate the population size of people who inject drugs (PWID) in Thai Nguyen-a province in the northern part of Vietnam. Two source capture-recapture population size estimates were calculated using data from two respondent driven sampling survey rounds conducted in 5 selected districts from May to August 2019. The population size of the PWID was calculated based on the number of PWID recruited in each survey and 'recaptured' during the first and the second survey. Additionally, personal network size data collected in the RDS was used to measure the population of PWID using the Successive Sampling Population Size Estimate (SS-PSE) method. The population of PWID estimated in five selected districts using the two capture-recapture method (CRC) (median = 5,396, 95% CI: 4,011-9,100) was slightly lower than estimated using SS-PSE with RDS survey 1 (median = 5,580, 95% CI: 3,024-9,272) and higher than when using SS-PSE with RDS survey 2 (median = 4,793; 95% CI: 2,310-8,618). The provincial PWID population estimates based on various approaches (e.g. extrapolation based on the prevalence of PWID in the districts) ranged from 6,498 (95% CI: 4,829-10,957) to around 6,807 (95% CI: 5,341-10,527). A provincial estimate of 6,782 PWID, with a confidence interval ranging from 5,312 to 10,527, will help guide planning and resource allocation to support appropriate levels of HIV prevention, care, and treatment services in the Thai Nguyen province.

Pre-exposure prophylaxis (PrEP) uptake and service delivery adaptations during the first wave of the COVID-19 pandemic in 21 PEPFAR-funded countries.

BACKGROUND: Mitigation measures for the first wave of the COVID-19 pandemic and burden on health systems created challenges for pre-exposure prophylaxis (PrEP) service delivery. We examined PrEP uptake in PEPFAR programs before and after the start of the COVID-19 pandemic. METHODS: We studied two PEPFAR program monitoring indicators, using routine Monitoring, Evaluation, Reporting (MER) indicators capturing uptake of PrEP (PrEP_NEW) and overall use of PrEP (PrEP_CURR). We also analyzed descriptive program narratives to understand successes and challenges field teams encountered after the start of the COVID-19 pandemic. To assess changes in coverage of PrEP across 21 countries, we calculated the "PrEP to need ratio" (PnR) using a published methodology. We defined the pre-COVID time period as April 1, 2019 -March 31, 2020 and the COVID time period as April 1, 2020 -March 31, 2021. FINDINGS: The total number of persons who initiated PrEP increased by 157% from 233,250 in the pre-COVID-19 period compared with 599,935 in the COVID-19 period. All countries, except five, noted significant increases in PrEP uptake. PrEP uptake among adolescent girls and young women (AGYW) increased by 159% from 80,452 AGYW in the pre-COVID-19 period to 208,607 AGYW in the COVID-19 period. There were 77,430 key populations (KP) initiated on PrEP in the pre-COVID-19 period and 209,114 KP initiated in the COVID-19 period (a 170% increase). The PnR increased 214% in the COVID-19 period across all PEPFAR-supported countries. Adaptations, such as multi-month dispensing (MMD) of PrEP; virtual demand creation activities; decentralized, community-based and virtual service delivery, were implemented to maintain PrEP services. CONCLUSIONS: PEPFAR programs continued to maintain and initiate new clients on PrEP despite the challenges posed by the COVID-19 pandemic. Adaptations such as MMD of PrEP and use of technology were vital in expanding service delivery and increasing PrEP coverage. FUNDING: This project has been supported by the U.S. President's Emergency Plan for AIDS Relief.

DEALING WITH INACCURATE MEASURES OF SIZE IN TWO-STAGE PROBABILITY PROPORTIONAL TO SIZE SAMPLE DESIGNS: APPLICATIONS IN AFRICAN HOUSEHOLD SURVEYS.

The units at the early stages of multi-stage area samples are generally sampled with probabilities proportional to their estimated sizes (PPES). With such a design, an overall equal probability (EP) sample design would yield a constant number of final stage units from each final stage cluster if the measures of size used in the PPES selection at each sampling stage were directly proportional to the number of final stage units. However, there are often sizable relative differences between the measures of size used in the PPES selections and the number of final stage units. Two common approaches for dealing with these differences are: (1) to retain a self-weighting sample design, allowing the sample sizes to vary across the sampled primary sampling units (PSUs) and (2) to retain the fixed sample size in each PSU and to compensate for the unequal selection probabilities by weighting adjustments in the analyses. This article examines these alternative designs in the context of two-stage sampling in which PSUs are sampled with PPES at the first stage, and an equal probability sample of final stage units is selected from each sampled PSU at the second stage. Two-stage sample designs of this type are used for household surveys in many countries. The discussion is illustrated with data from the Population-based HIV Impact Assessment surveys that were conducted using this design in several African countries.

Risk factors for pediatric invasive pneumococcal disease in the Intermountain West, 1996-2002.

PURPOSE: In response to concerns that the epidemiology of pediatric invasive pneumococcal disease (IPD) in the Intermountain West (i.e., Utah, Idaho, Wyoming, Montana, and parts of Arizona and Nevada) was poorly understood and might differ from elsewhere in the United States, a case-control study was undertaken to determine factors associated with IPD during 1996-2002. METHODS: A telephone questionnaire was administered to parents of children comprising 120 cases identified through hospital records and to parents of 156 age-matched controls located by random-digit dialing. The unit of analysis was each matched case-control set. RESULTS: Underlying chronic illness was reported for 32 (27%) of the cases. For previously healthy children, breastfeeding had a protective benefit (adjusted odds ratio: 0.2; 95% confidence interval [CI], 0.1-0.6), while a history of tympanostomy tube surgery was a risk factor (adjusted odds ratio: 12.6; 95% CI, 1.5-107.3). CONCLUSIONS: The presence of an underlying chronic illness was the strongest risk factor for IPD. Except for a history of tympanostomy tube surgery, the factors associated with IPD in this investigation were similar to those reported from other geographic regions. Tympanostomy surgery might serve as a surrogate indicator for predisposition to recurrent otitis media or decreased ability to clear pneumococcal infection, raising risk for invasive disease. Pediatric clinicians should continue to encourage breastfeeding, and continued emphasis on pneumococcal vaccination should help prevent IPD.

Binge drinking and occupation, North Dakota, 2004-2005.

INTRODUCTION: Binge drinking is a leading cause of preventable death and results in employee absenteeism and lost productivity. Knowledge about the prevalence of binge drinking among employees of different occupations is limited. METHODS: We assessed the prevalence of binge drinking (i.e., consuming five or more drinks per occasion during the previous 30 days) by primary occupation using data from the 2004-2005 North Dakota Behavioral Risk Factor Surveillance System. We used logistic regression to assess the association between binge drinking and primary occupation. RESULTS: Overall, 24.1% (95% confidence interval [CI], 22.5-25.7) of North Dakota workers reported binge drinking. The prevalence was highest among farm or ranch employees (45.3%; 95% CI, 28.3-63.4), food or drink servers (33.4%; 95% CI, 23.9-44.4), and farm or ranch owners (32.5%; 95% CI, 26.3-39.4). The prevalence was lowest among health care workers (13.2%; 95% CI, 10.3-16.8). Compared with health care workers, the adjusted odds of binge drinking were highest among farm or ranch employees (adjusted odds ratio [AOR], 2.2; 95% CI, 0.9-5.5), food or drink servers (AOR, 2.1; 95% CI, 1.1-4.0), and farm or ranch owners (AOR, 1.7; 95% CI, 1.1-2.6). Health insurance coverage was lowest among employees in occupations with the highest prevalence of binge drinking. CONCLUSION: We found occupational differences in the prevalence of binge drinking among employees in North Dakota. Many occupational categories had a high prevalence of binge drinking. We recommend the implementation of both employer-sponsored and population-based interventions to reduce binge drinking among North Dakota workers, particularly because employees in occupations with the highest rates of binge drinking had the lowest rates of health insurance coverage.

Health burden and funding at the Centers for Disease Control and Prevention.

BACKGROUND: The relationship between domestic funding for selected conditions to the Centers for Disease Control and Prevention (CDC) and the burden of disease and disability in the United States was assessed systematically. METHODS: Using mortality, years of potential life lost (YPLLs), disability-adjusted life years (DALYs), hospital days, hospital discharges, and direct medical costs of conditions, 34 high-burden conditions addressed by CDC programs were identified, and information was collected about the funds spent on each by CDC during fiscal year (FY) 2003. The 34 conditions were grouped into 15 categorical areas, and the relationship between budget and burden was analyzed using correlation and regression methods for each of the categorical areas and for each measure of burden. RESULTS: Of CDC's total FY 2003 budget of $6.9 billion, 62% ($4.3 billion) of funding was allocated to one of the 34 conditions studied. A positive relationship between budget and burden was identified for all measures of burden, although the correlations varied for the different conditions. CONCLUSIONS: Although examination of the relationship of CDC's budget to burden measures provides insight into the agency's portfolio of investments, this exercise also highlights a number of limitations with this approach and the currently available burden measures. Assessment of key public health functions such as emergency preparedness and the collection of vital statistics require development of metrics different from the burden measures used in this analysis. Investment in the development of such metrics warrants consideration.

School-based physical fitness testing identifies large disparities in childhood overweight in Los Angeles.

Few data are available on the epidemic of childhood overweight in local jurisdictions. To determine the prevalence and identify demographic and socioeconomic correlates of childhood overweight, we assessed height and weight data on 281,630 Los Angeles County, CA, public school students collected during school-based physical fitness testing in 2001. Overweight prevalence was 20.6% overall and varied by race/ethnicity: 25.2% among Latinos, 20.0% among Pacific Islanders, 19.4% among blacks, 17.6% among American Indians, 13.0% among whites, and 11.9% among Asians. By using multilevel analysis, we found that school-level percentage of students enrolled in free or reduced-price meal programs was independently associated with overweight, after controlling for school-level median household income and student-level demographic characteristics. When local overweight prevalence data are unavailable, percentage enrollment in free or reduced-price meal programs might be a useful indicator to identify schools where focused overweight prevention and control interventions are most needed.

Factors associated with adherence to antiretroviral therapy.

The purpose of this study was to examine the relationship of sociodemographic characteristics, patient perceptions, and patient characteristics including spirituality, self-reported adherence, and highly active antiretroviral therapy. The convenience sample consisted of 120 English-speaking adults (60% male, 35% female, 5% transgendered) with HIV/AIDS from two HIV service agencies in a large metropolitan city in the southeastern United States. The mean self-reported adherence was 83.1% (SD = 15.7%). Adherence was significantly correlated with perceived support and absence of barriers, strong intentions to adhere, perceived effectiveness of the medications, higher levels of perceived general health, fewer years of HIV disease, and fewer years on antiretroviral medications. Existential well-being (e.g., viewing life as positive and having meaning) was a weak significant correlate. Backward regression analysis was conducted to identify a parsimonious model of predictors of adherence. The final model included presence of support and absence of barriers, fewer years of HIV infection, no current alcohol use, perceived severity of HIV, existential well-being, and male gender. This model explained 19.4% of the variance in adherence (observed F[6, 100] = 5.6, p < .0001).

Detection of recent HIV-1 infection using a new limiting-antigen avidity assay: potential for HIV-1 incidence estimates and avidity maturation studies.

BACKGROUND: Accurate and reliable laboratory methods are needed for estimation of HIV-1 incidence to identify the high-risk populations and target and monitor prevention efforts. We previously described a single-well limiting-antigen avidity enzyme immunoassay (LAg-Avidity EIA) to detect recent HIV-1 infection. METHODS: We describe here further optimization and characterization of LAg-Avidity EIA, comparing it to the BED assay and a two-well avidity-index (AI) EIA. Specimen sets included longitudinal sera (n = 393), collected from 89 seroconverting individuals from 4 cohorts representing 4 HIV-1 subtypes, and sera from AIDS patients (n = 488) with or without TB co-infections from 3 different cohorts. Ninety seven HIV-1 positive specimens were purchased commercially. The BED assay, LAg-Avidity EIA, AI-EIA and HIV serology were performed, as needed. RESULTS: Monitoring quality control specimens indicated high reproducibility of the LAg-Avidity EIA with coefficient of variation of <10% in the dynamic range. The LAg-Avidity EIA has an overall mean duration of recency (ω) of 141 days (95% CI 119-160) at normalized optical density (ODn) cutoff of 1.0, with similar ω in different HIV-1 subtypes and populations (132 to 143 days). Antibody avidity kinetics were similar among individuals and subtypes by both the LAg-Avidity EIA and AI-EIA compared to the HIV-IgG levels measured by the BED assay. The false recent rate among individuals with AIDS was 0.2% with the LAg-Avidity EIA, compared to 2.9% with the BED assay. Western blot profiles of specimens with increasing avidity confirm accurate detection of recent HIV-1 infections. CONCLUSIONS: These data demonstrate that the LAg-Avidity EIA is a promising assay with consistent ω in different populations and subtypes. The assay should be very useful for 1) estimating HIV-1 incidence in cross-sectional specimens as part of HIV surveillance, 2) identifying risk factors for recent infections, 3) measuring impact of prevention programs, and 4) studying avidity maturation during vaccine trials.

Identifying risk factors for underimmunization by using geocoding matched to census tracts: a statewide assessment of children in Hawaii.

OBJECTIVE: Obtaining childhood immunization coverage data for small geographic areas is difficult and resource-intensive, especially in the absence of comprehensive immunization registries. To identify factors that are associated with delayed immunization, we collected school-entry immunization records statewide and used geocoding to link to publicly available census tract sociodemographic data. METHODS: Immunization records were reviewed for children who were enrolled in all public and private school kindergarten programs in Hawaii in the 2002-2003 school year; immunization status at the time of the second birthday was determined. The main outcome variable was up-to-date status for the 4:3:1:3:3 vaccination series (4 doses of diphtheria-tetanus-pertussis, 3 doses of polio, 1 dose of measles-mumps-rubella, 3 doses of Haemophilus influenzae type b, and 3 doses of hepatitis B vaccines). Children's home addresses were geocoded to census tracts; coverage rates by tract were mapped, and sociodemographic data from Census 2000 files were used to identify factors that were associated with delays in immunization. RESULTS: Records were obtained for 15,275 of 15,594 children registered in Hawaii kindergartens. Overall, 78% had completed their 4:3:1:3:3 series by their second birthday. Risk factors for delayed immunization included delayed immunization at 3 months of age, living in Maui County, living in a neighborhood where a low proportion of adults had postsecondary education, and living in a neighborhood where a high proportion of households spoke a language other than English at home. The majority (80%) of underimmunized children would have required only 1 additional visit to bring them up-to-date. CONCLUSIONS: Retrospective review of kindergarten-entry immunization data revealed geographic areas with lower immunization coverage, and geocoding to census tracts identified associated sociodemographic risk factors. This is a practical method for state or city health departments to identify pockets of need and to direct resources appropriately.

Keepin' it R.E.A.L.!: results of a mother-adolescent HIV prevention program.

BACKGROUND: The concern that adolescents may be placing themselves at risk for contracting HIV has led to widespread public and parental support for HIV prevention programs. Several programs on increasing communication between parents and teenagers have been tested, but the study of the impact of these programs on resulting sexual behavior is lacking. OBJECTIVE: To test the efficacy of two interventions for mothers and their adolescents in delaying initiation of sexual intercourse for youth who are not sexually active and encouraging the use of condoms among sexually active youth. METHODS: Employed were a control group and two treatment groups: one based on social cognitive theory (SCT) and the other a life skills program (LSK) based on problem behavior theory. Assessments were conducted before the intervention (baseline) and at 4, 12, and 24 months after the baseline assessment. RESULTS: Adolescents and their mothers (total N = 582) enrolled in the trial. At baseline, the adolescents ranged in age 11-14 years and were mostly male and African American. The mean age of the mothers was 37.9 years, and most were African American and single. The primary analyses showed no difference among groups in abstinence rates for adolescents. However, adolescents in the LSK group demonstrated an increase in the condom use rate, and those in the SCT and control groups scored higher on human immunodeficiency virus (HIV) knowledge than those in the LSK group. Mothers showed substantial increases over time in comfort talking about sex and self-efficacy. For HIV knowledge, mothers in the SCT group scored significantly higher than those in the LSK and control groups. CONCLUSION: The results of this study are comparable to previous studies that have included mothers in the HIV education of their adolescents. Although the program did not demonstrate a substantial effect on abstinence rates, increases were observed in condom use among adolescents and in mother's sex-based discussions and comfort in talking about sexual issues.

Family education and support interventions in heart failure: a pilot study.

BACKGROUND: Self-management of dietary sodium restriction by persons with heart failure (HF) is difficult and usually occurs within the home setting and within a family context. OBJECTIVE: To compare a patient and family education (EDUC) intervention with a combined education and family partnership intervention (EDUC + FPI) for effects on improving dietary sodium self-management in persons with HF. METHODS: Patients with HF and a family member (FM) were randomized to EDUC (n = 29 dyads) or EDUC + FPI (n = 32 dyads). Participants with HF were primarily White males with a mean age of 61 years (+/-12). The FMs were primarily women and spouses and had a mean age of 54 years (+/-17). Self-reported dietary sodium (Diet NA) intake and 24-hr urinary sodium (Urine NA) were measured at baseline (BL) and 3 months (3M) after intervention. Data were analyzed with descriptive statistics, generalized least squares regression, paired t test, and chi-square test. RESULTS: Groups did not differ by age, gender, or clinical variables; however, family functioning (Family APGAR) scores were slightly higher in the EDUC + FPI group at BL. Both groups decreased Diet NA and Urine NA from BL to 3M; the EDUC + FPI group showed greater decrease in Urine NA and had a greater percentage of those who decreased Urine NA by at least 15% (p = .04). Regression analysis to predict Urine NA revealed a significant Group x Time interaction (p = .03) when accounting for time-varying measures of body mass index (p = .001). DISCUSSION: A family-focused intervention may be useful in reducing dietary sodium intake in persons with HF. The Urine NA results support the importance of incorporating family-focused education and support interventions into HF care.

Vaccine effectiveness during a varicella outbreak among schoolchildren: Utah, 2002-2003.

OBJECTIVES: In the context of a chickenpox outbreak involving 2 Utah elementary schools, we conducted an investigation to assess vaccine effectiveness, describe illness severity, and examine risk factors for breakthrough varicella (ie, varicella in those who have been vaccinated). METHODS: All parents were asked to complete a questionnaire about their child's medical history. Parents of children with recent varicella were interviewed, and vaccination records were verified. Lesions were submitted for polymerase chain reaction testing. RESULTS: Questionnaires were returned for 558 (93%) of 597 students in school A and 924 (97%) of 952 students in school B. A total of 83 schoolchildren (57 unvaccinated and 26 vaccinated) had varicella during the October 2002 through February 2003 outbreak period. An additional 17 cases occurred among household contacts, including infants and adults. Polymerase chain reaction analysis recovered wild-type varicella. Vaccine effectiveness was 87%. With 1 notable exception, vaccinated children tended to have milder illness. Risk factors for breakthrough varicella included eczema, vaccination > or =5 years before the outbreak, and vaccination at < or =18 months of age. Restricting analysis to children vaccinated > or =5 years before the outbreak, those vaccinated at < or =18 months of age were more likely to develop breakthrough varicella (relative risk: 9.3; 95% confidence interval: 1.3-68.9). CONCLUSIONS: The vaccine, administered by >100 health care providers to 571 children during a 7-year time period, was effective. Risk factors for breakthrough varicella suggest some degree of biological interaction between age at vaccination and time since vaccination.

Use of Care, Outcomes and Costs of a Culturally-based Perinatal Program for Asian American and Pacific Islander Women in Hawaii.

PURPOSE. This study examines whether psychosocial perinatal care services developed through community partnerships and cultural deference with attention to individual women's health issues, had an assocaited impact on use of prenatal care, birth outcomes and perinatal care costs for the three participating Asian Pacific Islander American ethinc groups. METHODS. The use of prenatal care visits and birth outcomes for women in the Malama program were compared to those for women of the same etnic groups in the community prior to the introduction of the program. Data on program participants from 1992 to 1994 were compared to birth certificate data on Hawaiian, Filipino and Japanese women from 1988 to 1991. Costs of providing Malama prenatal services were determined from data provided by cost accounting and encounter data systems for the program. SUMMARY OF IMPORTANT FINDINGS. The use of prenatal care visits and birth outcomes were significantly lower for Malama program participants than for women of the same ethnic groups prior to the introduction of the program. The costs of the prenatal program services were $846 to $920 per woman. The expected savings in medical costs per infant with the improved preterm birth rates were $680 per infant. Thus 75% to 80% of the costs of the services were likely to be saved in lower medical costs of the infants. MAJOR CONCLUSIONS. Programs that use community approaches and caring servies delivered in a cultural context, like the Malama model, have a potential for improving the use of prenatal care and birth outcomes at reasonable costs. RELEVANCE TO ASIAN PACIFIC ISLANDER AMERICAN POPULATIONS. The Malama approach to ascertaining cultural preferences for the content and delivery of care should prove useful in addressing public health goals of improved pregnancy outcomes for diverse groups of Asian Americans and Pacific Islanders. KEY WORDS. Asian Americans/Pacific Islanders, pregnancy, prenatal care, low birthweight, preterm birth, cultural competency, community partnerships, costs, cost effectiveness.

The Seattle angina questionnaire: reliability and validity in women with chronic stable angina.

Angina pectoris causes substantial psychological and functional disability and adversely effects health-related quality of life, particularly in women. Studies of cardiac disease-specific quality of life in women with coronary artery disease and angina are limited because little reliability and validity data for these instruments exist for women. Therefore, the purpose of this study was to examine reliability and validity of the Seattle Angina Questionnaire (SAQ), a cardiac disease-related quality-of-life measure, in a sample of women with chronic stable angina. A secondary analysis was performed on SAQ data from 175 women with a confirmed diagnosis of CAD and angina pectoris. The majority of the women were older, white, living with their spouse, had a previous acute myocardial infarction, and had undergone revascularization. The Cronbach alpha was used to assess reliability of the SAQ's five subscales, and factor analysis was used to assess the SAQ's validity. Results suggest that the SAQ is a reliable and valid quality-of-life measure in women with CAD. The physical limitations subscale factored into two separate factors, suggesting that the subscale measures two domains of physical function: self-care and exercise tolerance/mobility. Future research is needed to determine whether examining different combinations of SAQ items might provide a more sensitive assessment of cardiac disease-specific quality of life in women.
