Exploring Pregnancy-Related Changes in Alcohol Consumption Between Black and White Women

ALCOHOLISM, Issue 3 2008
Daniel S. Morris
Background:, Although epidemiological data indicate that White women are more likely to drink and binge drink before pregnancy, fetal alcohol syndrome (FAS) is more common in the Black population than among Whites in the United States. Differences in drinking cessation between Black and White women who become pregnant may help explain the disparity in FAS rates. Methods:, The study sample was comprised of 280,126 non-Hispanic Black and White women, ages 18 to 44, from the Behavioral Risk Factor Surveillance System (BRFSS) 2001 to 2005 data sets. Predictors of reduction in alcohol consumption (in drinks per month) and binge drinking (>4 drinks on one occasion) by pregnant and non-pregnant women were identified with logistic regression. The effect of interactions of pregnancy status with age, education, and Black or White race on drinks per month and binge occasions were explored using analysis of variance (ANOVA). Results:, Pregnant White women averaged 79.5% fewer drinks per month than non-pregnant White women (F = 1250.1, p < 0.001), and 85.4% fewer binge drinking occasions (F = 376, p < 0.001). Pregnant Black women averaged 58.2% fewer drinks per month than non-pregnant Black women (F = 31.8, p < 0.001) and 64.0% fewer binge occasions (F = 13.8, p < 0.001). Compared to Black women, White women appear to make a 38% greater reduction in drinks per month, and a 33% greater reduction in binge occasions. Conclusions:, Non-Hispanic White women appear more likely to reduce drinks per month and binge drinking occasions than non-Hispanic Black women during pregnancy. These findings may help explain disparities in FAS in the United States, though this cross-sectional sample does not permit claims of causation. To better describe the impact of differential drinking reduction on FAS rates, future studies of longitudinal data should be done. [source]

Use of Clinical Guidelines for Treatment of Anemia Among Hemodialysis Patients

ARTIFICIAL ORGANS, Issue 2 2000
Mae Thamer
Abstract: Changing financial incentives have strongly influenced dosing patterns of recombinant human erythropoietin (rHuEPO) since its introduction in 1989. Although guidelines for prescribing rHuEPO exist, the extent to which they are adhered to is unknown. Using a retrospective cohort observational study design, the factors influencing the initial dosing of rHuEPO prescribed to 413 hemodialysis patients in 1994 were examined. Patient weight, the only recommended guideline, was not found to be a significant predictor of dosing of rHuEPO after controlling for selected patient demographic and clinical characteristics. The strongest predictor for initial rHuEPO dosing was hematocrit followed by White race (p < 0.05). Finally, each subsequent month was associated with a significantly larger initial rHuEPO dose, reflecting the general trend in increasing dose since 1991 (p < 0.001). In conclusion, despite the recent DOQI guidelines for treatment of anemia among persons with chronic renal failure, providers are not using patient weight as an independent criterion for determining dosing of rHuEPO.

Effects of prenatal cocaine exposure on special education in school-aged children . LevineT. P., LiuJ., DasA., LesterB., LagasseL., ShankaranS., BadaH. S., BauerC. R. & HigginsR. ( 2008 ) Pediatrics . Published online . DOI: 10.1542/peds.2007-2826 . Objective The objective of this study was to evaluate the effects of prenatal cocaine exposure on special education at age 7 with adjustment for covariates. Methods As part of the prospective, longitudinal, multi-site study of children with prenatal cocaine exposure (Maternal Lifestyle Study), school records were reviewed for 943 children at 7 years to determine involvement in special education outcomes: (1) individualized education plan; (2) special education conditions; (3) support services; (4) special education classes; and (5) speech and language services. Logistic regression was used to examine the effect of prenatal cocaine exposure on these outcomes with environmental, maternal and infant medical variables as covariates, as well as with and without low child IQ. Results Complete data for each analysis model were available for 737,916 children. When controlling for covariates including low child IQ, prenatal cocaine exposure had a significant effect on individualized education plan. When low child IQ was not included in the model, prenatal cocaine exposure had a significant effect on support services. Male gender, low birthweight, white race and low child IQ also predicted individualized education plan. Low birthweight and low child IQ were significant in all models. White race was also significant in speech and language services. Other covariate effects were model specific. When included in the models, low child IQ accounted for more of the variance and changed the significance of other covariates. Conclusions Prenatal cocaine exposure increased the likelihood of receiving an individualized education plan and support services, with adjustment for covariates. Low birthweight and low child IQ increased the likelihood of all outcomes. The finding that white children were more likely to get an individualized education plan and speech and language services could indicate a greater advantage in getting educational resources for this population.

COMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 5 2008
Hazem Seirawan
Abstract,,, Objectives:, To analyze the prevalence of dental visits within the last year in the Behavioral Risk Factor Surveillance System or BRFSS (2003) national database by simple sociodemographic factors, and to predict prevalence in States that have not participated in BRFSS 2003. Methods:, Behavioral Risk Factor Surveillance System is a cross-sectional telephone survey conducted by the state-level authorities in the United States and based on a standardized questionnaire to determine the distribution of risk behaviors and health practices among noninstitutionalized adults. A multivariable logistic regression model considers the complex sample design of the BRFSS was used to predict the prevalence of dental visits based on four nonclinic parsimonious variables. Results:, White race, high income (,$35 000), education above high school, and marital status were associated with an annual dental visit with odds ratios of 1.38, 2.09, 1.61, and 1.18, respectively. Utah had the highest percentage (78%) of estimated annual users, while ,Virgin Islands' had the lowest percentage (59%). The model's correct classification rate was 61.5%. Conclusions:, State and local governments, health promotion organizations, insurance companies, and organizations that administer public health programs (such as Medicare and Medicaid in the U.S.) will benefit by applying this model to the available nonclinical databases, and will be able to improve planning of dental health services and required dental workforce.

Risk of Hip Fracture in Disabled Community-Living Older Adults

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 1 2003
Louise C. Walter MD
OBJECTIVES: To determine the rate of hip fracture and risk factors associated with hip fractures in disabled older persons who enroll in the Program of All-Inclusive Care for the Elderly (PACE), a program providing comprehensive care to community-living nursing-home-eligible persons. DESIGN: Prospective cohort study between January 1990 and December 1997. SETTING: The twelve PACE demonstration sites: San Francisco, California; Columbia, South Carolina; Detroit, Michigan; Denver, Colorado; East Boston, Massachusetts; El Paso, Texas; Milwaukee, Wisconsin; Oakland, California; Portland, Oregon; Rochester, New York; Sacramento, California; and the Bronx, New York. PARTICIPANTS: Five thousand one hundred eighty-seven individuals in PACE; mean age 79, 71% female, 49% white, 47% with dementia. MEASUREMENTS: Functional status, cognitive status, demographics, and comorbid conditions were recorded on all the participants, who were tracked for occurrence of a hip fracture. The goals were to determine the rate of hip fracture and identify risk factors. RESULTS: Two hundred thirty-eight hip fractures (4.6%) occurred during follow-up. The rate of hip fracture was 2.2% per person-year. Four independent predictors of hip fracture were identified using Cox proportional hazard analysis: age of 75 and older (adjusted hazard ratio (HR) = 2.0, 95% confidence interval (CI) = 1.4,2.8); white ethnicity (HR = 2.1, 95% CI = 1.6,2.8); ability to transfer independently to and from bed, chair, and toilet (HR = 3.0, 95% CI = 1.2,7.2); and five or more Short Portable Mental Status Questionnaire errors (HR = 1.6, 95% CI = 1.3,2.1). The incidence of hip fracture ranged from 0.5% per person-year in persons with zero to one independent risk factors to 4.7% per person-year in those with all four independent risk factors. CONCLUSIONS: The rate of hip fracture in this cohort of disabled community-living older adults was similar to that reported in nursing home cohorts. Older age, white race, ability to transfer independently, and cognitive impairment were independent predictors of hip fracture. Persons with these risk factors should be targeted for preventive interventions, which should include strategies for making transferring safer. [source]

From White to Western: "Racial Decline" and the Idea of the West in Britain, 1890,1930

JOURNAL OF HISTORICAL SOCIOLOGY, Issue 3 2003
ALASTAIR BONNETT
It was a literature that, whilst claiming to defend and affirm white identity, in fact exposed the limits of whiteness as a form of social solidarity. It is shown how these studies drew together a variety of challenges deemed to be facing the white race and, more specifically, how they exhibited a contradictory desire to defend white racial community whilst attacking "the masses". The idea of the West, developing alongside, within and in the wake of this crisis literature, provided a less racially reductive but not necessarily less socially exclusive identity. [source]

Follow-up to a Federally Qualified Health Center and Subsequent Emergency Department Utilization

ACADEMIC EMERGENCY MEDICINE, Issue 1 2010
Tara M. Scherer MD
Abstract Objectives:, Determine if 1) proximity of referral to a federally qualified health center (FQHC) improves initial follow-up rates for discharged emergency patients, 2) improved initial follow-up rates are associated with improved rates for an "ongoing relationship" with the FQHC, and 3) an ongoing relationship with an FQHC is associated with decreased subsequent emergency department (ED) utilization over a 2-year follow-up period. Methods:, An expedited referral system was initiated just prior to January 2004 for discharged ED patients referred to an FQHC. Referral categories were as follows: R1 = next-day; R2 = 2 to 7 days; R3 = 2 to 3 weeks; and R4 = follow-up as needed. The FQHC database for 2004,2006 was merged with the ED database from 2004 through 2006. The FQHC database contained all ED referrals, the referral category, whether the patient kept his or her initial ED referral appointment, all subsequent scheduled clinic appointments, and whether the patient kept any of the subsequent scheduled appointments. We compared initial referral follow-up rates and subsequent scheduled visits to the FQHC for each referral category, over a 2-year follow-up period. We evaluated the effects of age, sex, marital status, insurance status, initial triage score, race, comorbidities, and number of prescription medications on initial follow-up, and subsequent kept appointments with the FQHC. We defined an "ongoing relationship" as one or more kept scheduled appointments annually. Finally, we compared the number of subsequent ED visits over the follow-up period between patients who maintained an ongoing relationship with the FQHC and those who did not, before and after correcting for the demographic and clinical factors. Results:, There were 520 referrals over the study period. Follow-up rates ranged from 37.5% (95% confidence interval [CI] = 13.5% to 69.6%) for R1 to 9.0% (95% CI = 4.4% to 17.0%) for R4. The overall ongoing relationship rate was 7.1% (95% CI = 5.2% to 9.7%) and had weak association with temporal proximity of referral. On bivariate analysis, older age, female sex, white race, one or more comorbidities, and three or more medications were associated with increased rates of initial follow-up. These factors (with the exception of race) were also associated with increased rates of developing an ongoing relationship. Patients with an ongoing relationship with the FQHC had more repeat ED visits over the study period than did patients without (3.6 vs. 1.7, p = 0.003). However, this difference was no longer evident after adjusting for age, race, comorbidities, and medication usage. Conclusions:, Overall patient follow-up to an FQHC was low, but increased with next-day or same-week referral. The ongoing relationship rate was low, but increased with temporal proximity of ED referral. Increased comorbidities and medication usage were significantly associated with increased initial follow-up rates, development of an ongoing relationship, and subsequent ED utilization. Patients with an ongoing relationship with the FQHC had higher ED utilization over the 2-year follow-up period, likely due to a higher rate of comorbidities.

Characteristics of teens with and without work permits

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 11 2009
Janet Abboud Dal Santo DrPH
Abstract Background Factors associated with the issuance of mandated work permits for teens, and their enforcement are currently unknown. Methods A cross-sectional survey was administered to 1945 teens at 16 randomly selected North Carolina high schools. Predictor variables examined included teens' socio-demographic characteristics, employment patterns, and labor law knowledge. Results One thousand and ninety-four non-working and 844 working teens participated. Seventy-seven percent of working teens worked during the school year and 39% started working younger than 16. The majority (80%) worked in retail and services. Forty-four percent worked without work permits. Factors associated with being less likely to be issued a work permit included white race, employment in a family-owned business, being a laborer, and limited or no knowledge of child labor laws. Conclusions Adherence to and enforcement of the work permit system is low. Interventions should specifically target teens who work in family owned businesses, in unskilled labor and in hazardous industries. Am. J. Ind. Med. 52:841,849, 2009. © 2009 Wiley-Liss, Inc.

Identifying High Risk Groups and Quantifying Absolute Risk of Cancer After Kidney Transplantation: A Cohort Study of 15 183 Recipients

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 9 2007
A. C. Webster
Transplant recipients have increased cancer risk, but data on risk variation across different patient groups are sparse. Rates and standardized rate ratios (SRR) of cancer (all sites, excluding nonmelanocytic skin and lip cancer) compared to the general population were calculated, using Australia and New Zealand Dialysis and Transplant Registry data. Within the transplant population, risk factors were identified (hazard ratios: HR; 95% CI) and absolute risk estimated for recipient groups. A total of 1642 (10.8%) of 15 183 recipients developed cancer. Risk was inversely related to age (SRR 15,30 children, 2 if >65 years). Females aged 25,29 had rates equivalent to women aged 55,59 from the general population. Age trend for lymphoma, colorectal and breast risk was similar; melanoma showed less variability across ages, prostate showed no risk increase. Within the transplanted population, risk was affected by age differently for each sex (p = 0.007), elevated by prior malignancy (HR 1.40; 1.03,1.89), white race (HR 1.36; 1.12,1.89), but reduced by diabetic end-stage kidney disease (ESKD) (HR 0.67; 0.50,0.89). Cancer rates in kidney recipients are similar to nontransplanted people 20,30 years older, but absolute risk differs across patient groups. Men aged 45,54 surviving 10 years have cancer risks varying from 1 in 13 (non-white, no prior cancer, diabetic ESKD) to 1 in 5 (white, prior cancer, other ESKD). [source]

Neuroimaging for Pediatric Head Trauma: Do Patient and Hospital Characteristics Influence Who Gets Imaged?

ACADEMIC EMERGENCY MEDICINE, Issue 7 2010
Rebekah Mannix MD
ACADEMIC EMERGENCY MEDICINE 2010; 17:694,700 © 2010 by the Society for Academic Emergency Medicine Abstract Objectives:, The objective was to identify patient, provider, and hospital characteristics associated with the use of neuroimaging in the evaluation of head trauma in children. Methods:, This was a cross-sectional study of children (,19 years of age) with head injuries from the National Hospital Ambulatory Medical Care Survey (NHAMCS) collected by the National Center for Health Statistics. NHAMCS collects data on approximately 25,000 visits annually to 600 randomly selected hospital emergency and outpatient departments. This study examined visits to U.S. emergency departments (EDs) between 2002 and 2006. Multivariable logistic regression was used to analyze characteristics associated with neuroimaging in children with head injuries. Results:, There were 50,835 pediatric visits in the 5-year sample, of which 1,256 (2.5%, 95% confidence interval [CI] = 2.2% to 2.7%) were for head injury. Among these, 39% (95% CI = 34% to 43%) underwent evaluation with neuroimaging. In multivariable analyses, factors associated with neuroimaging included white race (odds ratio [OR] = 1.5, 95% CI = 1.02 to 2.1), older age (OR = 1.3, 95% CI = 1.1 to 1.5), presentation to a general hospital (vs. a pediatric hospital, OR = 2.4, 95% CI = 1.1 to 5.3), more emergent triage status (OR = 1.4, 95% CI = 1.1 to 1.8), admission or transfer (OR = 2.7, 95% CI = 1.4 to 5.3), and treatment by an attending physician (OR = 2.0, 95% CI = 1.1 to 3.7). The effect of race was mitigated at the pediatric hospitals compared to at the general hospitals (p < 0.001). Conclusions:, In this study, patient race, age, and hospital-specific characteristics were associated with the frequency of neuroimaging in the evaluation of children with closed head injuries. Based on these results, focusing quality improvement initiatives on physicians at general hospitals may be an effective approach to decreasing rates of neuroimaging after pediatric head trauma.

A population-based description of glioblastoma multiforme in Los Angeles County, 1974,1999

CANCER, Issue 12 2005
Indro Chakrabarti M.D., M.P.H.
Abstract BACKGROUND There have been reports that the incidence rates of brain tumors have increased over the past few decades, but most have considered all brain tumors together. The authors analyzed the pattern of glioblastoma multiforme (GBM) occurrence in Los Angeles County, California to shed light on the incidence and descriptive epidemiology of this type of brain tumor. METHODS Data were obtained from the Los Angeles County Cancer Surveillance Program. Incidence rates were analyzed by gender, race, age at diagnosis, period of diagnosis (1974,1981, 1982,1988, or 1989,1999), and socioeconomic status (SES). In addition, data were stratified according to anatomic subsite. A multivariate model describing changes in rates by each of these variables was constructed. RESULTS Age-specific incidence rates (ASIR) rose sharply after age 30 years. The peak ASIR was at age 70,74 years in males and at age 75,79 years in females. The age-adjusted incidence rate (AAIR) of GBM increased from 1974 to 1999 by an estimated 2.4% per year among males and 2.8% per year among females. Overall, males had a 60% increased risk of brain tumors compared with females. Males had a higher incidence of GBM compared with females at each anatomic subsite except the posterior fossa. The largest male:female ratio occurred in the occipital lobes. Non-Latino whites had the highest incidence rates (2.5 per 100,000) followed by Latino whites (1.8 per 100,000), and blacks (1.5 per 100,000). After 1989, compared with the period before magnetic resonance imaging (MRI) was available, there was an increase in GBM incidence rates among those with of higher SES that was most pronounced in females. The incidence of GBM was highest for frontal lobe tumors and for tumors that involved two or more lobes (overlapping tumors), followed by tumors in the temporal and parietal lobes. In the multivariate analysis, year of diagnosis, SES, gender, race (Latino but not black), site, and age at diagnosis all were important predictors of incidence rate. CONCLUSIONS GBM incidence increased in Los Angeles County over the last 30 years and especially after 1989, suggesting that the introduction of MRI may have contributed to the increase. Individuals older than age 65 years experienced the greatest increase in incidence over time. Older age, male gender, higher SES, and non-Latino white race increased the risk of GBM. Previously unreported incidence rates for GBM among Latino whites were significantly lower than among non-Latino whites but were intermediate between non-Latino whites and blacks.
