ABSTRACT

BACKGROUND: Maternal education has been shown repeatedly to be inversely associated with preterm birth. Both preterm birth and educational level of families are correlated across generations, but it is not clear if educational level of grandparents affects the risk of preterm delivery of their grandchildren, and, if so, if the association with grandmother's education is independent of mother's education. METHODS: We used New Jersey birth certificates to create a transgenerational dataset to examine the effect of grandmother's education on risk of PTB in White, Black and Hispanic grandchildren. We matched birth certificates of girls born in 1979-1983 to mothers listed on NJ birth certificates for the years 1999-2011. Thus, grandmothers were the women delivering in 1979-1983, and mothers were those born to the grandmothers who in turn delivered grandchildren in 1999-2011. We performed descriptive tabulations and multivariate logistic regression to develop risk estimates. RESULTS: Overall, maternal education was associated inversely with PTB in each of the demographic groups. There was a substantial inter-generational increase in education between grandmothers and mothers in each group, which was most striking in Hispanics After adjusting for maternal age and education, grandmother's education continued to be associated with preterm birth of her grandchildren. CONCLUSIONS: Grandmother's education was an additional, independent predictor of PTB in her grandchildren. This result supports the idea that mother's childhood and preconception socioeconomic environment, including the educational level of her childhood household affect her reproductive health.

ABSTRACT

PURPOSE: This study aimed to compare diagnosis and treatment delays in elderly breast cancer patients with and without pre-existing mental illness. METHODS: A retrospective cohort study was conducted using the Surveillance, Epidemiology and End Results-Medicare data including 16,636 women 68+ years, who were diagnosed with stage I-IIIa breast cancer in the United States from 2005 to 2007. Mental illness was identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes recorded on inpatient and outpatient claims during the 3 years prior to breast cancer diagnosis. Patients were classified as having no mental illness, anxiety, depression, anxiety and depression, or severe mental illness (bipolar disorder, schizophrenia, and other psychotic disorder). Multivariable binomial regression was used to assess the association between mental illness and delays of ≥60 and ≥90 days after adjustment for confounders. RESULTS: Patients with comorbid anxiety and depression had an increased risk for diagnosis delay of ≥90 days from symptom recognition (RR 1.11; 95% CI 1.00, 1.23), and those with severe mental illness had an increased risk for initial treatment delay of ≥60 days from diagnosis (RR 1.36; 95% CI 1.06, 1.74). Patients with any mental illness experienced an increased risk for adjuvant chemotherapy delay of ≥90 days from last operation (RR 1.13; 95% CI 1.01, 1.26) and each category of mental illness, except depression, showed a non-significant trend for this association. CONCLUSION: Breast cancer patients with mental illness should be closely managed by a cross-functional care team, including a psychiatrist, a primary care physician, and an oncologist, to ensure adequate care is received within an appropriate timeframe.

ABSTRACT

PURPOSE: In an effort to explain racial disparities in breast cancer survival, this study aimed to investigate how comorbidity affects breast cancer-specific mortality by race. METHODS: A retrospective cohort study was conducted using the Surveillance, Epidemiology and End Results-Medicare linked data including 68,090 women 66+ years, who were diagnosed with stage I-III breast cancer in the United States from 1994 to 2004. Hospital and outpatient claims from the year prior to breast cancer diagnosis were used to identify comorbid conditions and patients were followed for survival through 2010. RESULTS: Competing risk survival analysis failed to demonstrate any negative comorbidity effects on breast cancer-specific survival for black women. An increased breast cancer-specific mortality hazard was observed for white women who had diabetes without complication relative to white women without this condition after adjusting for age and year of diagnosis (hazard ratio: 1.22, 95% confidence interval 1.13, 1.30). The Cochran-Armitage Test showed diabetes was associated with a later stage of diagnosis (p < 0.01) and a more aggressive tumor grade (p < 0.01) among white women in the study population. CONCLUSION: Race specific comorbidity effects do not explain breast cancer-specific survival disparities. However, the relationship between diabetes and breast cancer, including the role of aggressive tumor characteristics, warrants special attention.

ABSTRACT

BACKGROUND: Blood transfusion might affect long-term mortality by changing immune function and thus potentially increasing the risk of subsequent infections and cancer recurrence. Compared with a restrictive transfusion strategy, a more liberal strategy could reduce cardiac complications by lowering myocardial damage, thereby reducing future deaths from cardiovascular disease. We aimed to establish the effect of a liberal transfusion strategy on long-term survival compared with a restrictive transfusion strategy. METHODS: In the randomised controlled FOCUS trial, adult patients aged 50 years and older, with a history of or risk factors for cardiovascular disease, and with postoperative haemoglobin concentrations lower than 100 g/L within 3 days of surgery to repair a hip fracture, were eligible for enrolment. Patients were recruited from 47 participating hospitals in the USA and Canada, and eligible participants were randomly allocated in a 1:1 ratio by a central telephone system to either liberal transfusion in which they received blood transfusion to maintain haemoglobin level at 100 g/L or higher, or restrictive transfusion in which they received blood transfusion when haemoglobin level was lower than 80 g/L or if they had symptoms of anaemia. In this study, we analysed the long-term mortality of patients assigned to the two transfusion strategies, which was a secondary outcome of the FOCUS trial. Long-term mortality was established by linking the study participants to national death registries in the USA and Canada. Treatment assignment was not masked, but investigators who ascertained mortality and cause of death were masked to group assignment. Analyses were by intention to treat. The FOCUS trial is registered with ClinicalTrials.gov, number NCT00071032. FINDINGS: Between July 19, 2004, and Feb 28, 2009, 2016 patients were enrolled and randomly assigned to the two treatment groups: 1007 to the liberal transfusion strategy and 1009 to the restrictive transfusion strategy. The median duration of follow-up was 3·1 years (IQR 2·4-4·1 years), during which 841 (42%) patients died. Long-term mortality did not differ significantly between the liberal transfusion strategy (432 deaths) and the restrictive transfusion strategy (409 deaths) (hazard ratio 1·09 [95% CI 0·95-1·25]; p=0·21). INTERPRETATION: Liberal blood transfusion did not affect mortality compared with a restrictive transfusion strategy in a high-risk group of elderly patients with underlying cardiovascular disease or risk factors. The underlying causes of death did not differ between the trial groups. These findings do not support hypotheses that blood transfusion leads to long-term immunosuppression that is severe enough to affect long-term mortality rate by more than 20-25% or cause of death.

ABSTRACT

PURPOSE: The purpose of this study was to determine the effects of breast cancer on chronic disease medication adherence among older women. METHODS: The Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked data and a 5% random sample of Medicare enrollees were used. Stage I-III breast cancer patients diagnosed in 2008 and women without cancer were eligible. Three cohorts of medication users 66+ years were identified using diagnosis codes and prescription fill records: diabetes, hypertension, and lipid disorders. For each cohort, breast cancer patients were frequency matched to comparison women by age and geographic area. Medication adherence was measured by the proportion of days covered and medication persistence. RESULTS: During the post-baseline period, the percentage of breast cancer patients who were non-adherent was 26.2% for diabetes medication, 28.9% for lipid-lowering medication, and 14.2% for hypertension medication. Breast cancer patients experienced an increased odds of diabetes medication non-adherence [odds ratio (OR) = 1.44; 95% confidence interval (CI) = 1.07 to 1.95] and were more likely to be non-persistent with diabetes medication (hazard ratio = 1.31; 95%CI: 1.04 to 1.66) relative to women without cancer. The study failed to show a difference between breast cancer and comparison women in the odds of non-adherence to hypertensive (OR = 0.87; 95%CI: 0.71 to 1.05) or lipid-lowering medication (OR = 0. 91; 95%CI: 0.73 to 1.13) with a proportion of days covered threshold of 80%. CONCLUSION: Special attention should be given to the coordination of primary care for older breast cancer patients with diabetes. Copyright © 2016 John Wiley & Sons, Ltd.

ABSTRACT

BACKGROUND: The hemoglobin threshold at which postoperative red-cell transfusion is warranted is controversial. We conducted a randomized trial to determine whether a higher threshold for blood transfusion would improve recovery in patients who had undergone surgery for hip fracture. METHODS: We enrolled 2016 patients who were 50 years of age or older, who had either a history of or risk factors for cardiovascular disease, and whose hemoglobin level was below 10 g per deciliter after hip-fracture surgery. We randomly assigned patients to a liberal transfusion strategy (a hemoglobin threshold of 10 g per deciliter) or a restrictive transfusion strategy (symptoms of anemia or at physician discretion for a hemoglobin level of <8 g per deciliter). The primary outcome was death or an inability to walk across a room without human assistance on 60-day follow-up. RESULTS: A median of 2 units of red cells were transfused in the liberal-strategy group and none in the restrictive-strategy group. The rates of the primary outcome were 35.2% in the liberal-strategy group and 34.7% in the restrictive-strategy group (odds ratio in the liberal-strategy group, 1.01; 95% confidence interval [CI], 0.84 to 1.22), for an absolute risk difference of 0.5 percentage points (95% CI, -3.7 to 4.7). The rates of in-hospital acute coronary syndrome or death were 4.3% and 5.2%, respectively (absolute risk difference, -0.9%; 99% CI, -3.3 to 1.6), and rates of death on 60-day follow-up were 7.6% and 6.6%, respectively (absolute risk difference, 1.0%; 99% CI, -1.9 to 4.0). The rates of other complications were similar in the two groups. CONCLUSIONS: A liberal transfusion strategy, as compared with a restrictive strategy, did not reduce rates of death or inability to walk independently on 60-day follow-up or reduce in-hospital morbidity in elderly patients at high cardiovascular risk.

ABSTRACT

PURPOSE: To examine the role of preoperative magnetic resonance imaging (pMRI) on time to surgery and rates of reoperation and contralateral prophylactic mastectomy (CPM) using a population-based study of New Jersey breast cancer patients. METHODS: The study included 289 African-American and 320 white women who participated in the Breast Cancer Treatment Disparity Study and underwent breast surgery for newly diagnosed early-stage breast cancer between 2005 and 2010. Patients were identified through rapid case ascertainment by the New Jersey State Cancer Registry. Association between pMRI and time to surgery was examined by using linear regression and, with reoperation and CPM, by using binomial regression. RESULTS: Half (49.9 %) of the study population received pMRI, with higher use for whites compared with African-Americans (62.5 vs. 37.5 %). After adjusting for potential confounders, patients with pMRI versus those without experienced significantly longer time to initial surgery [geometric mean = 38.7 days; 95 % confidence interval (CI) 34.8-43.0; vs. 26.5 days; 95 % CI 24.3-29.0], a significantly higher rate of CPM [relative risk (RR) = 1.82; 95 % CI 1.06-3.12], and a nonsignificantly lower rate of reoperation (RR = 0.76; 95 % CI 0.54-1.08). CONCLUSIONS: Preoperative MRI was associated with significantly increased time to surgery and a higher rate of CPM, but it did not affect the rate of reoperation. Physicians and patients should consider these findings when making surgical decisions on the basis of pMRI findings.

ABSTRACT

OBJECTIVE: We previously reported an increased risk of stillbirth associated with increases in trimester-specific ambient air pollutant concentrations. Here, we consider whether sudden increase in the mean ambient air pollutant concentration immediately before delivery triggers stillbirth. METHODS: We used New Jersey linked fetal death and hospital discharge data and hourly ambient air pollution measurements from particulate matter ≤ 2.5 mm (PM2.5), carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2) monitors across New Jersey for the years 1998-2004. For each stillbirth, we assigned the concentration of air pollutants from the closest monitoring site within 10 km of the maternal residence. Using a time-stratified case-crossover design and conditional logistic regression, we estimated the relative odds of stillbirth associated with interquartile range (IQR) increases in the mean pollutant concentrations on lag day 2 and lag days 2 through 6 before delivery, and whether these associations were modified by maternal risk factors. RESULTS: The relative odds of stillbirth increased with IQR increases in the mean concentrations of CO (odds ratio [OR] = 1.20, 95% confidence interval [CI] = 1.05-1.37), SO2 (OR = 1.11, 95% CI = 1.02-1.22), NO2 (OR = 1.11, 95% CI = 0.97-1.26), and PM2.5 (OR = 1.07, 95% CI = 0.93-1.22) 2 days before delivery. We found similar associations with increases in pollutants 2 through 6 days before delivery. These associations were not modified by maternal risk factors. CONCLUSION: Short-term increases in ambient air pollutant concentrations immediately before delivery may trigger stillbirth.

ABSTRACT

The purpose of the present study was to examine the risk of stillbirth associated with ambient air pollution during pregnancy. Using live birth and fetal death data from New Jersey from 1998 to 2004, the authors assigned daily concentrations of air pollution to each birth or fetal death. Generalized estimating equation models were used to estimate the relative odds of stillbirth associated with interquartile range increases in mean air pollutant concentrations in the first, second, and third trimesters and throughout the entire pregnancy. The relative odds of stillbirth were significantly increased with each 10-ppb increase in mean nitrogen dioxide concentration in the first trimester (odds ratio (OR) = 1.16, 95% confidence interval (CI): 1.03, 1.31), each 3-ppb increase in mean sulfur dioxide concentration in the first (OR = 1.13, 95% CI: 1.01, 1.28) and third (OR = 1.26, 95% CI: 1.03, 1.37) trimesters, and each 0.4-ppm increase in mean carbon monoxide concentration in the second (OR = 1.14, 95% CI: 1.01, 1.28) and third (OR = 1.14, 95% CI: 1.06, 1.24) trimesters. Although ambient air pollution during pregnancy appeared to increase the relative odds of stillbirth, further studies are needed to confirm these findings and examine mechanistic explanations.

ABSTRACT

BACKGROUND: Statins are some of the most commonly prescribed medications in medical practice, and prostate cancer is the most common malignancy among men. Although there has been no consistent evidence that statins affect cancer incidence, including prostate cancer, several reports suggest they may decrease the rate of advanced prostate cancer. However, no study to date has specifically examined statin use and prostate cancer mortality. The authors conducted this population-based case-control investigation to examine this association. METHODS: This was a matched case-control study. Cases were residents of New Jersey ages 55 to 79 years who died from prostate cancer between 1997 and 2000. The cases were matched individually to population-based controls by 5-year age group and race. Medication data were obtained identically for cases and controls from blinded medical chart review. Conditional logistic regression was used to adjust for confounders. RESULTS: In total, 718 cases were identified, and cooperation was obtained from 77% of their spouses (N = 553). After a review of medical records, 387 men were eligible, and 380 were matched to a control. The unadjusted odds ratio was 0.49 (95% confidence interval, 0.34-0.70) and decreased to 0.37 (P < .0001) after adjusting for education, waist size, body mass index, comorbidities, and antihypertensive medication. There was little difference between lipophilic and hydrophilic statins, but more risk reduction was noted for high-potency statins (73%; P < .0001) compared with low-potency statins (31%; P = .32). CONCLUSIONS: Statin use was associated with substantial protection against prostate cancer death, adding to the epidemiologic evidence for an inhibitory effect on prostate cancer.

ABSTRACT

OBJECTIVE: Delays in treatment initiation may contribute to the poorer breast cancer survival among Black women compared with Whites. Lower socioeconomic status and lack of access to care are other reasons for the observed disparities. We, therefore, examined racial differences in treatment delays for early breast cancer in a similarly insured population of Medicaid beneficiaries. DESIGN AND SETTING: A retrospective cohort study using linked New Jersey Cancer Registry and Medicaid Research files using logistic regression models. PATIENTS: 237 Black and 485 White women aged 20-64 years diagnosed with early breast cancer between 1997 and 2001. MAIN OUTCOME MEASURE: Delays in treatment initiation. RESULTS: Blacks experience adjuvant chemotherapy delays more often than Whites. Black women had two-fold odds (95% confidence interval, 1.04, 4.38) of > or = 3 months delay in adjuvant chemotherapy than Whites. Blacks were also more likely to experience radiation treatment delays but this finding was not statistically significant (odds ratio 1.72, 95% CI .79, 3.77). No racial differences were observed for surgical and hormonal treatment delays. CONCLUSION: Blacks experienced delays in initiating adjuvant chemotherapy more frequently than Whites. These differences were observed even in a population with similar socioeconomic status and insurance access, suggesting that cultural and psychosocial factors may contribute to the observed differences.

ABSTRACT

OBJECTIVE: We compared lifestyle CVD risk factors between Asian Indian and White non-Hispanic men within categories of BMI. DESIGN/SETTING/PARTICIPANTS: Participants included 51,901 White non-Hispanic men and 602 Asian Indian men enrolled in the California Men's Health Study cohort. Men were aged 45-69 years and members of Kaiser Permanente Southern or Northern California at baseline (2001-2002). MAIN OUTCOME MEASURES: Lifestyle characteristics including diet, physical activity, alcohol intake and smoking were collected from a survey. Multivariable logistic regression, adjusting for demographics, was performed. RESULTS: Asian Indians more often reported a healthy BMI (18.5-24.9), and consumed < 30% calories from fat within each BMI category (healthy weight and overweight/obese). Among healthy weight men, Asian Indians were less likely to eat -5 fruit and vegetables a day. Overall, Asian Indians were more likely to have never smoked and to abstain from alcohol. Asian Indians were less likely to report moderate/vigorous physical activity > or = 3.5 hours/week. No differences were found in sedentary activity. CONCLUSIONS: We identified health behaviors that were protective (lower fat intake, lower levels of smoking and alcohol) and harmful (lower levels of physical activity and fruit and vegetable intake) for cardiovascular health among the Asian Indians in comparison to White non-Hispanics. Results stratified by BMI were similar to those overall. However, the likelihood of consuming a low fat diet was lower among healthy weight men, while fruit and vegetable consumption, physical activity and alcohol intake was greater. These results suggest risk factors other than lifestyle behaviors may be important contributors to CVD in the Asian Indian population.

ABSTRACT

BACKGROUND: The purpose of this analysis was to examine potential associations between absence, extended (repeated) absence, tardiness, and repeated tardiness from school and doctor-diagnosed asthma. METHODS: A cross-sectional analysis was conducted using data collected in fall 2007 on 914 4th and 5th grade school children from seven randomly selected participating schools in DeKalb County, GA. ANOVA was used to compare attendance metrics for race, gender, and asthma status groups. Nonparametric Kruskal-Wallis statistical tests were also done because distributions of attendance metrics were skewed. We tallied daily absence data during the study period and examined absence by day of week. We also compared the variation of the weekly rate of absence and tardiness for students with asthma versus students without asthma over the study period. RESULTS: The mean days of absence in 86 students with asthma was 2.73 days compared with 1.89 days for 828 children without asthma (p = .004). There was no significant difference in mean days of tardiness by asthma status. The difference in the number of instances of 2+ consecutive days of absence (extended absence) by asthma status was not significant. Students with asthma were more likely to be absent on Mondays (p = .005), Tuesdays (p = .001), and Fridays (p = .02) than students without asthma. The weekly rate of tardiness for students with asthma trended with the general student study population over the study period, whereas the weekly rate of absence did not. CONCLUSIONS: Asthma was associated with increased 1-day absences but not longer absences or tardiness.

ABSTRACT

Black breast cancer patients have shorter survival compared to whites. Lack of optimal treatment may be a potential explanation for this difference. Although racial disparities in surgical and radiation therapy have been studied extensively, there is little information on racial disparities in use of adjuvant systemic therapy. Medicaid enrolled patients provide an opportunity to examine racial disparity in breast cancer treatment by minimizing the roles of access to health care and socioeconomic status. This study, therefore, compared breast cancer treatment, particularly adjuvant systemic therapy and survival in black and white women enrolled in Medicaid. Linked New Jersey Cancer Registry and Medicaid Research files provided diagnostic, prognostic, and treatment information on 237 black and 485 white women aged 20-64 years diagnosed with early stage breast cancer between January 1997 and December 2001. Racial differences in treatment and survival were examined using logistic regression and Cox proportional hazards models respectively. There were no differences in surgical, radiation, or adjuvant systemic treatment between blacks and whites. Breast cancer specific mortality (Hazard ratio (HR) = 1.37; 95% confidence interval (CI) = 0.94-1.98) and all-cause mortality (HR = 1.43; 95% CI = 1.08-1.89) were higher among blacks than whites. In this study of Medicaid-enrolled women with similar socioeconomic status and health care access, blacks and whites received similar breast cancer treatment. In spite of this, blacks had higher mortality than whites. Our findings suggest that factors other than treatment differences may contribute to the racial disparity in mortality.

ABSTRACT

Dry steam cleaning, which has gained recent attention as an effective method to reduce house dust mite (HDM) allergen concentration and loading in carpets, was evaluated in this study for its efficacy in lowering levels of polycyclic aromatic hydrocarbons (PAHs) as well as HDM allergens. Fifty urban homes with wall-to-wall carpets, mostly low-income and with known lead contamination, were studied in 2003 and 2004. Two carpet-cleaning interventions were compared: Repeated HEPA (High Efficiency Particulate Air filtered) vacuuming alone and repeated HEPA vacuuming supplemented with dry steam cleaning. Vacuum samples were collected to measure carpet loading of dust and contaminants immediately before and after cleaning. Paired comparisons were conducted to evaluate the effectiveness of the cleaning protocols in reducing the levels of PAHs and HDM allergens in carpets. The results indicated that both cleaning methods substantially reduced the loading of PAHs and HDM allergens as well as dust in carpets (p < 0.0001). The reductions in loading of dust (64.4%), PAHs (69.1%), and HDM allergens (85.5%), by dry steam cleaning plus repetitive HEPA vacuuming were larger than the reductions by regular HEPA vacuuming alone: dust (55.5%), PAHs (58.6%), and HDM allergens (80.8%), although the difference was statistically significant only for dust and PAHs. We conclude that intensive HEPA vacuum cleaning substantially reduced the loading of PAHs and HDM allergens in carpets in these urban homes and that dry steam cleaning added modestly to cleaning effectiveness.

ABSTRACT

The purpose of this study was to describe the population structure of group B streptococci (GBS) isolated from infected and colonized neonates during a prospective active-surveillance study of early-onset disease in six centers in the United States from July 1995 to June 1999 and to examine its relationship to bovine strains of GBS. The phylogenetic lineage of each GBS isolate was determined by multilocus sequence typing, and isolates were clustered into clonal complexes (CCs) using the eBURST software program. A total of 899 neonatal GBS isolates were studied, of which 129 were associated with invasive disease. Serotype Ia, Ib, and V isolates were highly clonal, with 92% to 96% of serotype Ia, Ib, and V isolates being confined to single clonal clusters. In contrast, serotype II and III isolates were each comprised of two major clones, with 39% of serotype II and 41% of serotype III isolates in CC 17 and 41% of serotype II and 54% of serotype III isolates in CC 19. Further analysis demonstrates that the CC 17 serotype II and III GBS are closely related to a previously described "ancestral" lineage of bovine GBS. While 120 (93%) of invasive GBS were confined to the same lineages that colonized neonates, 9 (7%) of the invasive GBS isolates were from rare lineages that comprised only 2.7% of colonizing lineages. These results are consistent with those for other geographic regions that demonstrate the highly clonal nature of GBS infecting and colonizing human neonates.

ABSTRACT

BACKGROUND: There is no available evidence from randomized trials that early detection of prostate cancer improves health outcomes, but the prostate-specific antigen (PSA) test is commonly used to screen men for prostate cancer. OBJECTIVE: The objective of the study is to see if screening with PSA decreases mortality from prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: This is a case-control study using one-to-one matching on race, age, and time of availability of exposure to PSA screening. Decedents, 380, from New Jersey Vital Statistics 1997 to 2000 inclusive, 55-79 years of age at diagnosis were matched to living controls without metastatic prostate cancer. Medical records were obtained from all providers, and we abstracted information about PSA tests from 1989 to the time of diagnosis in each index case. MEASUREMENTS: Measurements consist of a comparison of screening (yes, no) between cases and controls. Measure of association was the odds ratio. RESULTS: Eligible cases were diagnosed each year from 1989 to 1999 with the median year being 1993. PSA screening was evident in 23.2-29.2% of cases and 21.8-26.1% of controls depending on the screening criteria. The unadjusted, matched odds ratio for dying of prostate cancer if ever screened was 1.09 (95% CI 0.76 to 1.60) for the most restrictive criteria and 1.19 (95% CI, 0.85 to 1.66) for the least restrictive. Adjustment for comorbidity and education level made no significant differences in these values. There were no significant interactions by age or race. CONCLUSIONS: PSA screening using an ever/never tabulation for tests from 1989 until 2000 did not protect New Jersey men from prostate cancer mortality.

ABSTRACT

BACKGROUND: Whether the association between teenage pregnancy and adverse birth outcomes could be explained by deleterious social environment, inadequate prenatal care, or biological immaturity remains controversial. The objective of this study was to determine whether teenage pregnancy is associated with increased adverse birth outcomes independent of known confounding factors. METHODS: We carried out a retrospective cohort study of 3,886,364 nulliparous pregnant women <25 years of age with a live singleton birth during 1995 and 2000 in the United States. RESULTS: All teenage groups were associated with increased risks for pre-term delivery, low birth weight and neonatal mortality. Infants born to teenage mothers aged 17 or younger had a higher risk for low Apgar score at 5 min. Further adjustment for weight gain during pregnancy did not change the observed association. Restricting the analysis to white married mothers with age-appropriate education level, adequate prenatal care, without smoking and alcohol use during pregnancy yielded similar results. CONCLUSIONS: Teenage pregnancy increases the risk of adverse birth outcomes that is independent of important known confounders. This finding challenges the accepted opinion that adverse birth outcome associated with teenage pregnancy is attributable to low socioeconomic status, inadequate prenatal care and inadequate weight gain during pregnancy.

ABSTRACT

OBJECTIVE: Vulvodynia is a chronic pain syndrome of unknown origin with scant data on frequency. This study assessed the prevalence of vulvodynia symptoms in a sample of US women and compared health characteristics of symptomatic and asymptomatic women. STUDY DESIGN: A phone survey contacted 2127 US households to identify 100 symptomatic women, who were matched on age and time zone to 325 asymptomatic controls. Odds ratios (ORs) and logistic regression were used to model associations between pain, medical conditions, and health care utilization variables. RESULTS: Current vulvar pain of at least 6 months duration was reported by 3.8% of respondents, with a 9.9% lifetime prevalence. Forty-five percent of women with pain reported an adverse effect on their sexual life and 27% an adverse effect on their lifestyle. Cases more frequently reported repeated urinary tract infections (OR, 6.15; 95% CI, 3.51-10.77) and yeast infections (OR, 4.24; 95% CI, 2.47-7.28). Associations existed with chronic fatigue syndrome (OR, 2.78; 95% CI, 1.33-6.19), fibromyalgia (OR, 2.15; 95% CI, 1.06-4.36), depression (OR, 2.99; 95% CI, 1.87-4.80), and irritable bowel syndrome (OR, 1.86; 95% CI, 1.07-3.23). CONCLUSION: Lifetime chronic vulvar pain was less prevalent in this national sample of women than previous data suggest and was correlated with several comorbid chronic medical conditions and substantial reduction in self-reported quality of life.
