Wrist fracture as a predictor of future fractures in younger versus older postmenopausal women: results from the National Osteoporosis Risk Assessment (NORA).

UNLABELLED: The short-term association between wrist-fracture history and future fracture has not been simultaneously compared between younger and older postmenopausal women. This 3-year follow-up study of 158,940 women showed a similar future fracture risk in younger and older women with wrist-fracture history. INTRODUCTION: We examined the association between prior wrist fracture and future osteoporosis-related fractures within 3 years in younger and older postmenopausal women. METHODS: In the National Osteoporosis Risk Assessment (NORA) study, 158,940 postmenopausal women, aged 50-98 (median 63) years, provided information on fracture history since age 45, and responded to follow-up surveys 1 or 3 years later when new fractures were queried. Cox regression models were used to obtain relative risk (RR) and 95% confidence interval (CI) estimates. RESULTS: Of the 158,940 participants, 8,665 reported a history of wrist fracture at baseline; 4,316 women reported at least one new fracture within three years. The RR for any subsequent clinical fracture, adjusted for covariates and baseline BMD T-score, was 2.4 (2.0, 2.9) for younger and 2.1 (1.9, 2.3) for older women. A prior wrist fracture increased the risk of a future wrist fracture about 3-fold and doubled the risk of any osteoporotic fracture. CONCLUSIONS: Prior wrist fracture strongly predicts three-year risk of any future osteoporotic fracture for older and younger postmenopausal women, independent of baseline BMD and common osteoporosis risk factors. More consideration should be given to evaluating and managing osteoporosis in younger and older women with a history of wrist fracture, independent of their BMD.

Insight into patient dissatisfaction with asthma treatment.

BACKGROUND: Measures of patient satisfaction or dissatisfaction with treatment are increasingly being used as indicators of quality of care. As these measures become more widely used, it is important to know if patient dissatisfaction is associated with important processes or outcomes of medical care. METHODS: Survey of patient-reported asthma management issues using the Asthma Therapy Assessment Questionnaire in a large health maintenance organization in the Pacific Northwest. Associations between patient dissatisfaction with asthma treatment and patient-reported measures of asthma control, patient-provider communication, and belief in asthma medications (self-efficacy) were examined. RESULTS: Of the 5181 adult members with asthma enrolled in the health maintenance organization, 30% indicated dissatisfaction with current treatment. Dissatisfaction was higher among patients with a higher number of asthma control problems, patient-provider communication problems, or belief in medication problems (eg, failure to believe their medications are useful and inability to take asthma medications as directed). The odds of dissatisfaction with treatment were 2.8 (95% confidence interval [CI], 2.4-3.3; P<.001) for asthma control problems, 2.0 (95% CI, 1.6-2.6; P<.001) for communication problems, and 8.0 (95% CI, 6.7-9.5; P<.001) for belief in medication problems compared with patients without these perceived problems. CONCLUSION: Patient dissatisfaction with treatment may be related to important asthma disease management issues.

Consistency of care with national guidelines for children with asthma in managed care.

OBJECTIVE: To evaluate the consistency of pediatric asthma care with the National Asthma Education and Prevention Program Guidelines. DESIGN: Cross-sectional survey at 2 managed care organizations in the United States (winter 1997-1998). The participants were parents of children (n = 318) age 5 to 17 years with asthma. There were no interventions. The outcome measures were indicators of care in 4 domains: (1) periodic physiologic assessment, (2) proper use of medications, (3) patient education, and (4) control of factors contributing to asthma severity. RESULTS: Of 533 eligible patients with asthma, 318 (60%) parents responded; 59% of children were male, 76% were white, and 60% were aged 5 to 10 years. Deficiencies in care were identified in all care domains including, for patients with moderate and severe persistent symptoms, only 55% used long-term control medication daily, 49% had written instructions for handling asthma attacks, 44% had instructions for adjustment of medication before exposures, 56% had undergone allergy testing, and 54% had undergone pulmonary function testing. CONCLUSIONS: There are significant opportunities to improve the quality of care for children with asthma enrolled in managed care. A comprehensive approach to improving care may be necessary to address multiple aspects of care where opportunities exist.

Prevalence and predictors of highly active antiretroviral therapy use in patients with HIV infection in the united states. HCSUS Consortium. HIV Cost and Services Utilization.

BACKGROUND: Highly active antiretroviral therapy (HAART) became standard for HIV in 1996. Studies at that time showed that most people infected with HIV had initiated HAART, but that members of minority groups and poor people had lower HAART use. It is not known whether high levels of HAART use have been sustained or whether socioeconomic and racial disparities have diminished over time. OBJECTIVES: To determine the proportion of patients who had received and were receiving HAART by January 1998, and to evaluate predictors of HAART receipt. DESIGN AND PARTICIPANTS: Prospective cohort study of a national probability sample of 2267 adults receiving HIV care who completed baseline, first follow-up, and second follow-up interviews from January 1996 to January 1998. MAIN OUTCOME VARIABLES: Proportion currently using HAART at second follow-up (August 1997 to January 1998), contrasted with the cumulative proportions using HAART at any time before January 1998 and before December 1996. ANALYSES: Bivariate and multiple logistic regression analysis of population characteristics predicting current use of HAART at the time of the second follow-up interview. RESULTS: The proportion of patients ever having received HAART increased from 37% in December 1996 to 71% by January 1998, but only 53% of people were receiving HAART at the time of the second follow-up interview. Differences between sociodemographic groups in ever using HAART narrowed after 1996. In bivariate analysis, several groups remained significantly less likely to be using HAART at the time of the second follow-up interview: blacks, male and female drug users, female heterosexuals, people with less education, those uninsured and insured by Medicaid, those in the Northeast, and those with CD4 counts of >/=500 cells/microl (all p <.05). Using multiple logistic regression analysis, low CD4 count (for CD4 <50 cells/microl: odds ratio [OR], 3.20; p <.001) remained a significant predictor of current HAART use at the time of the second follow-up interview, but lack of insurance (OR, 0.71; p <.05) predicted not receiving HAART. CONCLUSIONS: The proportion of persons under HIV care in the United States who had ever received HAART increased to over 70% of the affected population by January 1998 and the disparities in use between groups narrowed but did not disappear. However, nearly half of those eligible for HAART according to the U.S. Department of Health and Human Services guidelines were not actually receiving it nearly 2 years after these medications were first introduced. Strategies to promote the initiation and continuation of HAART are needed for those without contraindications and those who can tolerate it.

Use of simvastatin treatment in patients with combined hyperlipidemia in clinical practice. For the Simvastatin Combined Hyperlipidemia Registry Group.

OBJECTIVE: To describe and understand current care of simvastatin-treated patients with combined hyperlipidemia in routine clinical practice. DESIGN: A 6-month prospective observational study. Demographics, simvastatin dosage, cardiac risk factors, and lipid profile were collected from August 1997 to December 1998 at 20 sites (230 patients) across the United States. RESULTS: Overall mean percentage of reduction in total cholesterol levels was 27% (P<.001), low-density lipoprotein cholesterol (LDL-C) was 35% (P<.001), and triglyceride values was 28% (P<.001). Among those patients with low baseline high-density lipoprotein cholesterol (HDL-C) values (<0.91 mmol/L [<35 mg/dL]) (N = 49), there was a 17% increase in HDL-C (P< or =.001); 35% of these patients achieved National Cholesterol Education Program HDL-C goal (ie, < or =0.91 mmol/L [> or =35 mg/dL]). Coronary heart disease (CHD) patients were given significantly higher initial doses (mean, 15.1 mg) compared with non-CHD patients (mean, 11.5 mg) (P< or =.001). Overall, 74% of patients achieved LDL-C goal (52% on starting dose, 22% after 1 titration). Among those patients who were not at goal and had a follow-up lipid profile result available, only 1 patient (2%) was at the maximum dose (80 mg); 69% were receiving 20 mg or less. Approximately 63% of patients with CHD, 80% of patients with 2 or more risk factors, and 91% of patients with fewer than 2 risk factors achieved LDL-C goal. CONCLUSIONS: Multiple factors contribute to LDL-C goal achievement in a usual care setting. A significant opportunity exists to increase the number of patients who achieve LDL-C goal by appropriate dose titration and/or give patients a higher initial dose of simvastatin.

Survey of migraineurs referred to headache specialists: care, satisfaction, and outcomes.

The authors report a survey of 281 migraineurs recently referred to headache specialists by primary care physicians. Compared with care before referral, specialists spent substantially more time with patients and were more likely to ask patients to take a prophylactic drug and to keep a headache diary, to discuss migraine triggers, and to prescribe 5-hydroxytryptamine1B/1D agonists (triptans). After referral, patients reported improved satisfaction with care and significant decreases in frequency, duration, and severity of attacks.

Comparing asthma care for Medicaid and non-Medicaid children in a health maintenance organization.

OBJECTIVE: To compare ambulatory visit patterns, rates of medication use, and emergency department and hospital utilization for children with asthma covered under Medicaid and commercial payers within the same health maintenance organization (HMO). DESIGN: Retrospective cohort study. SETTING: Eleven staff-model pediatric departments of an HMO. PATIENTS: A total of 1928 Medicaid and 11007 non-Medicaid children aged 2 to 18 years with at least 1 encounter with a diagnosis of asthma between October 1, 1991, and September 30, 1996. METHODS: We linked patient-level data from the HMO's automated medical record system for ambulatory encounters, a claims system for emergency department and hospital care, and an automated pharmacy dispensing database. Medicaid and non-Medicaid patients were compared for all encounter types and for prescribing and dispensing of beta-agonist and controller medications (inhaled corticosteroids and cromolyn sodium). Incidence rate ratios were calculated from Poisson regression models to control for age, sex, and, when appropriate, beta-agonist dispensing rate. The number of refills authorized on each prescription and the fraction of medications dispensed as refills compared with new prescriptions were compared for Medicaid and non-Medicaid patients. RESULTS: Medicaid-insured children in the HMO were 1.4 times (95% confidence interval, 1.2-1.5) more likely to receive care in emergency departments and 1.3 times (95% confidence interval, 1.1-1.5) more likely to be hospitalized for their asthma compared with non-Medicaid members. Medicaid and non-Medicaid enrollees had similar yearly rates of nonurgent (1.32 vs 1.17) and urgent (0.38 vs 0.31) ambulatory visits. Beta-agonists were dispensed roughly equally to Medicaid and non-Medicaid members. Although Medicaid patients were less likely to have controller medications dispensed (relative risk, 0.72; 95% confidence interval, 0.69-0.74), they were equally likely to have them prescribed. CONCLUSIONS: Differences in ambulatory contact for Medicaid members do not explain the higher rates of emergency department visits and hospitalization in this population. Reasons for lower rates of dispensing of controller medications should continue to be investigated as one cause of increased morbidity for low-income children with asthma.

Use of antiretroviral therapies by HIV-infected persons receiving methadone maintenance.

HIV-infected persons receiving methadone maintenance must often seek their medical care at a separate site. However, little data is available on the receipt of antiretroviral therapy (ART), beliefs about ART, and influences on the decision to initiate ART among those referred off-site. HIV-infected injection drug users (n = 72) were interviewed at three methadone maintenance programs; 83% with CD4 cell counts under 500 reported that they had received ART. Of these persons, 56% had used three drug combination therapy. Beliefs about the benefits of ART included: increased survival, 96%; decreased viral load 87%; decreased HIV-related infections 87%; could cure HIV, 29%. For those receiving ART, physician input, CD4 count, and possible side effects were more important than friends, family or mass media in deciding to start ART. We conclude that the model of referral for HIV care off-site does not appear to impede access to ART for HIV-infected IDUs in methadone maintenance.

Costs of care for HIV infection in a managed care population from 1995 to 1997.

OBJECTIVE: To determine costs of drug and nondrug treatment of HIV-infected patients during introduction of protease inhibitors and combination therapy. STUDY DESIGN: Longitudinal, observational study of insurance claims data. PATIENTS AND METHODS: Data from managed care organizations in Texas and California contracting with an HIV case management group were reviewed for all non-Medicaid/non-MediCal adults infected with HIV for costs of drugs and nondrug treatment per HIV-infected member per month from January 1995 to December 1997. Costs of care for patients with and without undetectable viral loads (< 400 copies/mL) were quantified. RESULTS: Per HIV-infected member, average monthly drug costs increased, nondrug costs decreased, and total costs remained stable. Quarterly mortality rates decreased from 4.8% to 0.25%. From the first quarter of 1996 to the last quarter of 1997, the proportion of patients with undetectable viral loads increased from 6% to 56%. Increasing drug costs and decreasing nondrug costs were observed in patients with and without undetectable viral loads, but costs were higher for the latter: after the second quarter of 1996, drug costs were $67 to $277 higher for patients without undetectable viral loads, nondrug costs were $185 to $741 higher, and total costs were $333 to $808 higher. CONCLUSIONS: Reduced mortality rates and increased viral suppression to undetectable levels were observed during introduction of protease inhibitors and combination therapy in this MCO setting. Increased average monthly drug costs per HIV-infected patient were offset by decreased average monthly nondrug costs, and both costs were lower when patients achieved undetectable viral loads.

Association of asthma control with health care utilization and quality of life.

Asthma severity and level of asthma control are two related, but conceptually distinct, concepts that are often confused in the literature. We report on an index of asthma control developed for use in population-based disease management. This index was measured on 5,181 adult members of a large health maintenance organization (HMO), as were various self-reported measures of health care utilization (HCU) and quality of life (QOL). A simple index of number of control problems, ranging from none through four, exhibited marked and highly significant cross-sectional associations with self- reported HCU and with both generic and disease-specific QOL instruments, suggesting that each of the four dimensions of asthma control represented by these problems correlates with clinically significant impairment. Qualitatively similar results were found for control problems assessed relative to the past month and relative to the past year. Asthma control is an important "vital sign" that may be useful both for population-based disease management as well as for the management of individual patients.

Quality-of-life questionnaire for patients taking antihypertensive medication.

This study was undertaken to construct a health-related quality-of-life (QOL) questionnaire for hypertensive patients from preexisting instruments and to validate its use in full form and in a shortened version. Two hundred seventy hypertensive patients who were stable while taking antihypertensive medication (control group), changing medication because of side effects, or newly treated for hypertension were enrolled in a prospective, observational, longitudinal study. At baseline and at months 1, 2, and 3, patients completed a questionnaire covering 7 domains of QOL. The criteria for evaluating the scales were internal consistency, test-retest reliability, construct validity, and responsiveness to change. Data were analyzed for the full questionnaire and the shortened version. Internal consistency and test-retest correlation values were 0.69 to 0.95 for scales in the full questionnaire and 0.57 to 0.92 in the shortened version. Construct validity was supported by statistically significant, positive correlations with a global QOL item for all but 1 scale in both versions. Responsiveness to change was supported by increases in scores between baseline and month 3 for all scales in patients changing their medication because of side effects; scores remained unchanged (on all but 1 scale) in the stable (control) group. By uniformly applying standard validation criteria to a set of preexisting instruments, we created a new QOL questionnaire. Results were similar in both the full form and shortened version.

Relationship between ambulatory care accessibility and hospitalization for persons with advanced HIV disease.

Specific features of ambulatory care, such as accessibility, may influence hospital use for patients with HIV infection. To identify clinic features associated with a lower risk of hospitalization, 6,280 New York state Medicaid enrollees diagnosed with AIDS in 1987-1992 and managed by one of 157 surveyed clinics were studied. The odds of hospitalization in the year before AIDS diagnosis were associated with five clinic features that facilitate the accessibility of care: (1) evening/weekend hours, (2) case manager, (3) appointments within 48 hours, (4) telephone consultation, and (5) whether the clinic handled urgent care. Hospitalization in the year before AIDS diagnosis occurred for 49 percent of patients. Three of the five accessibility features had unadjusted associations with lower hospitalization rates. The adjusted odds of hospitalization were lower for patients in clinics with extended hours (OR = 0.77, 95% CI = 0.63, 0.93) and for patients in clinics with four or more accessibility features compared with those in clinics with less than two features (OR = 0.67; 95% CI = 0.50, 0.89).

Burden of migraine in the United States: disability and economic costs.

BACKGROUND: Migraine is a common disabling disease but its economic burden has not been adequately quantified. OBJECTIVE: To estimate the burden of migraine in the United States with respect to disability and economic costs. METHODS: The following data sources were used: published data, the Baltimore County Migraine Study, MEDSTAT's MarketScan medical claims data set, and statistics from the Census Bureau and the Bureau of Labor Statistics. Disability was expressed as bedridden days. Charges for migraine-related treatment were used as direct cost inputs. The human capital approach was used in the estimation of indirect costs. RESULTS: Migraineurs required 3.8 bed rest days for men and 5.6 days for women each year, resulting in a total of 112 million bedridden days. Migraine costs American employers about $13 billion a year because of missed workdays and impaired work function; close to $8 billion was directly due to missed workdays. Patients of both sexes aged 30 to 49 years incurred higher indirect costs compared with younger or older employed patients. Annual direct medical costs for migraine care were about $1 billion and about $100 was spent per diagnosed patient. Physician office visits accounted for about 60% of all costs; in contrast, emergency department visits contributed less than 1% of the direct costs. CONCLUSIONS: The economic burden of migraine predominantly falls on patients and their employers in the form of bedridden days and lost productivity. Various screening and treatment regimens should be evaluated to identify opportunities to reduce the disease burden.

The relationship of clinic experience with advanced HIV and survival of women with AIDS.

OBJECTIVE: Hospital and physician experience have been linked to improved outcomes for persons with HIV. Because many HIV-infected patients receive care in clinics, we studied clinic HIV experience and survival for women with AIDS. DESIGN: Retrospective cohort study of women with AIDS whose dominant sources of care were clinics. Clinic HIV experience was estimated as the cumulative number of Medicaid enrollees with advanced HIV who used a particular clinic as their dominant provider up to the year of the patient's AIDS diagnosis: low experience (< 20 patients), medium (20-99 patients), high (> or = 100 patients). Proportional hazards models examined relationships between experience and survival. SETTING: A total of 117 New York State clinics. PATIENTS: A total of 887 New York State Medicaid-enrolled women diagnosed with AIDS in 1989-1992. MAIN OUTCOME MEASURE: Survival after AIDS diagnosis. RESULTS: In later study years (1991-1992), patients in high experience clinics had an approximately 50% reduction in the relative hazard of death (0.53; 95% confidence interval, 0.35-0.82) compared with patients in low experience clinics. Adjusting for demographic and clinical variables, 71% of patients in high experience clinics were alive 21 months after diagnosis compared with 53% in low experience clinics. Experience and survival were not significantly associated in the early study years (1989-1990). CONCLUSIONS: In more recent years, women with AIDS receiving care in high experience clinics survived longer after AIDS diagnosis than those in low experience clinics, providing further evidence of a relationship between provider HIV experience and outcomes.

Repeated emergency department use by HIV-infected persons: effect of clinic accessibility and expertise in HIV care.

Repeated emergency department (ED) visits by HIV-infected persons may signify poor access to care or treatment from inexperienced ambulatory providers. We examined features of 157 clinics following 6820 HIV-infected patients and associations with repeated (> or =2) ED visits by these patients in the year before their first AIDS diagnosis. Patient clinical and health care data came from 1987-1992 New York State (NYS) Medicaid files and clinic data came from interviews of clinic directors. The HIV/AIDS experience of each study patient's clinic was measured as the annual number of Medicaid enrollees newly diagnosed with AIDS who were contemporaneously followed by the patient's clinic. Repeated ED use was observed for 24%. The adjusted odds ratio (AOR) of repeated ED visits was reduced for patients in clinics with a physician on-call (0.77; 95% confidence interval [CI] = 0.65, 0.92), evening or weekend clinic hours (0.77; 95% CI = 0.64, 0.93), or >50 AIDS patients/year in 1987-1988 (0.56; 95% CI = 0.44, 0.71) versus fewer patients in those years. Patients in clinics with more than one feature promoting accessibility or HIV expertise had a greater reduction in their AOR of repeated ED use. HIV-infected patients in clinics with greater accessibility and HIV expertise rely less on the ED for care.

Cigarette smoking and maternal-child HIV transmission.

We investigated the association of cigarette smoking with maternal-child HIV transmission, adjusting for illicit drug use, maternal clinical status, and delivery factors. Vital statistics birth data were linked to the New York State Medicaid HIV/AIDS Research Database for HIV-infected women delivering a liveborn singleton from 1988 through 1990. Follow-up of these children was accomplished by Medicaid data > or = 2 years after birth, and their HIV status was ascertained by a clinically based classification. The adjusted relative risk or hazard (RH) of transmission for maternal factors was determined from Cox models. The overall transmission was 24.5% for the 901 maternal-child pairs. Smokers comprised 40% of women with data on smoking (n = 768); their transmission rate was 31% versus 22% for nonsmokers (p = 0.02). In the entire cohort, the adjusted RH of transmission for smokers was 1.45 (95% confidence interval [CI] 1.07-1.96); among women with advanced HIV, the adjusted RH was even higher (RH = 1.71; 95% CI 1.14-2.58). Users of cocaine (15% of the cohort) or of mixed or unspecified illicit drugs (28%) had higher transmission rates in unadjusted analysis (33%, p = 0.06 and 31%, p = 0.06 respectively); after adjustment for smoking and other maternal factors, neither cocaine (RH = 1.04 (95% CI 0.66-1.63)) nor mixed nor unspecified drug use (RH = 1.13 (95% CI = 0.75-1.70)) was significantly associated with transmission. Our data document an association of cigarette smoking during pregnancy with an increased risk of maternal-child HIV transmission that can be added to the growing list of complications caused by cigarette smoking.

Clinic services for persons with AIDS. Experience in a high-prevalence state.

OBJECTIVE: To profile characteristics of clinics caring for persons with advanced HIV infection. DESIGN AND SETTING: Survey of clinic directors in New York State. PARTICIPANTS: Newly diagnosed Medicaid-enrolled AIDS patients in New York state in federal fiscal years 1987-1992 (n = 6,184) managed by 62 HIV specialty, 53 hospital-based general medicine/primary care, 36 community-based primary care, and 28 other clinics. MEASUREMENTS AND MAIN RESULTS: Telephone survey about clinic hours, emphasis on HIV, staffing, procedures, and directors' rating of care. Estimates of the number of newly diagnosed, Medicaid-enrolled AIDS patients treated in surveyed clinics were obtained from claims data. We found that community-based clinics were significantly more likely to have longer hours, a physician on call, or to accommodate unscheduled care than were hospital-based general medicine/ primary care or other types of clinics. Compared with HIV specialty clinics, general medicine/primary care clinics were less likely to have HIV-specific care attributes such as a director of HIV care (98% vs 72%), multidisciplinary conferences on HIV care (83% vs 32%), or a standard initial HIV workup (90% vs 70%). Of general medicine/primary care clinics, most (83%) were staffed by residents and fellows compared with only 68% of HIV or 25% of community-based clinics (p < .001). General medicine/primary care clinics were less likely than community-based clinics to perform Pap smears (75% vs 94%) or to have case managers on payroll (21% vs 81%). CONCLUSIONS: In this sample of clinics, hospital-based general medicine/primary care clinics managing the care of Medicaid enrollees with AIDS appeared to have more limited hours and availability of specific services than HIV specialty or community-based clinics.

Issues in the measurement of satisfaction with treatment.

Patients satisfaction with treatments is a growing area of research that has tremendous potential to provide outcome measures for clinical trials and disease management programs. It also has applications in marketing and product development, especially for the treatment of chronic diseases. The objective of this review is to demonstrate that treatment satisfaction is a distinct area of research that has produced some important initial results. We define treatment satisfaction and provide a conceptual framework that clarifies the role of treatment expectations, preferences, and satisfaction in the context of healthcare in general. Nineteen articles were selected from more than 1,400 abstracts and were reviewed for the following information: (1) topics covered; (2) method used to design the measure; (3) descriptive statistics; (4) assessment with respect to the attributes in the Instrument Review Criteria of the Medical Outcome Trust's Scientific Advisory Committee; and (5) covariates. We conclude that some important initial results about treatment satisfaction have been obtained, but that much work remains to be performed. We recommend that future research devote more attention to qualitative research with patients, assessment of the measures, and the covariates presented in the conceptual model. We also recommend that decision makers insist on measures that meet these criteria.

Association of maternal HIV infection with low birth weight.

We evaluated factors associated with low birth weight (LBW) in an HIV-infected cohort (n = 772) and a general sample (n = 2,377) of women delivering a live singleton in federal fiscal years 1989 and 1990 while enrolled in New York State Medicaid. The association of LBW and HIV infection was studied in logistic models, controlling for illicit drug use, demographic characteristics, adequacy of prenatal care, and medical risk factors. Overall, 29% of the HIV-infected women had a LBW infant compared to 9.3% of the general sample (p < 0.001). The adjusted odds of LBW for HIV-infected women were twofold higher than for uninfected women [odds ratio (OR) = 2.04 and 95% confidence interval (Cl) = 1.54, 2.69]. Odds of LBW were also increased for illicit drug users (OR = 2.16; 95% CI = 1.59, 2.94), cigarette smokers (OR = 1.81; 95% CI = 1.37, 2.39), and African-American versus non-Hispanic white women (OR = 1.89; 95% CI = 1.31, 2.72). Lower odds appeared for women with adequate prenatal care (OR = 0.54; 95% CI = 0.42, 0.68). Among only women with full-term deliveries, the association of HIV with LBW remained strong as we found nearly threefold greater odds of LBW for HIV-infected women. This study indicates that HIV-infected women have an increased risk of bearing a L.BW infant, even after adjusting for the effects of drug use, health care delivery, and other social and medical risk factors.
