Risk factors associated with incident clinical vertebral and nonvertebral fractures in postmenopausal women: the Canadian Multicentre Osteoporosis Study (CaMos).

Utilizing data from the Canadian Multicentre Osteoporosis Study (CaMos), we examined the association between potential risk factors and incident vertebral and nonvertebral fractures. A total of 5,143 postmenopausal women were enrolled. Information collected during the study included data from the CaMos baseline and annually mailed fracture questionnaires, the Short Form 36 (SF-36), the Health Utilities Index, and physical measurements. Participants were followed for 3 years. Postmenopausal women were classified into four groups according to their incident fracture status since baseline: those without a new fracture; those with a new clinically recognized vertebral fracture; those with an incident nonvertebral fracture at the wrist, hip, humerus, pelvis, or ribs (main nonvertebral fracture group); and those with any new nonvertebral fracture (any-nonvertebral-fracture group). We performed multivariate Cox proportional hazard analysis using all possible risk factors to determine the association between risk factors and the time to the first minimal trauma fracture. Best predictive models were also determined using variables that were included in the full models. The Bayesian information criterion was used for model selection. For all analyses, relative risks and associated 95% confidence intervals were calculated. During the follow-up period, 34, 163, and 280 women developed a vertebral, a main nonvertebral, or any nonvertebral fracture, respectively. The best predictive models indicated that a five point lower quality of life as measured by the SF-36 physical component summary score was associated with relative risks of 1.21 (95% CI, 1.02 to 1.44), 1.17 (95% CI, 1.07 to 1.28), and 1.19 (95% CI, 1.11 to 1.27) for incident vertebral, main nonvertebral, and all nonvertebral fractures, respectively. In addition, for a one standard deviation (SD=0.12) lower femoral neck BMD, the relative risks for incident vertebral, main nonvertebral, and any nonvertebral fractures increased by 2.73 (95% CI, 1.74 to 4.28), 1.39 (95% CI, 1.06 to 1.82), and 1.34 (95% CI, 1.09 to 1.65), respectively. Furthermore, various anthropometric measures, disease conditions, and medications are associated with a new fracture. Identifying postmenopausal women at risk is important given that fracture prevention therapies are now available.

Diet and risk of leukemia in the Iowa Women's Health Study.

Nearly 30,000 individuals ages over 21 years are diagnosed with leukemia each year in the United States. Other than benzene, radiation, and chemotherapy, which account for a small proportion of cases, there are few identified risk factors for adult leukemia. Although recent data from animal studies indicate a potentially protective role for dietary restriction in leukemogenesis, few data exist on dietary relationships in adult leukemia. Food frequency data collected at baseline (1986) were analyzed from the prospective Iowa Women's Health Study to begin to address the role of diet in adult leukemia. Data from 35,221 women ages 55-69 years were analyzed. A total of 138 women developed leukemia during the 14-year follow-up period of 1986 to 1999. With the exception of an inverse association (P trend = 0.08) with increasing consumption of all vegetables (relative risk, 0.56 and 95% confidence interval, 0.36-0.88; relative risk, 0.69 and 95% confidence interval, 0.44-1.07 for medium and high consumption, respectively), there was little evidence of an important role for other dietary factors in leukemogenesis. Analyses that excluded cases diagnosed in the first 2 years from baseline did not notably alter the results. Leukemia subgroups, including acute myeloid leukemia and chronic lymphoblastic leukemia, were also analyzed, but no statistically significant associations with dietary factors were revealed. This study provides evidence that increased vegetable consumption may decrease the risk of adult leukemia. However, given that our study focused on older women from a defined geographical area, analyses of prospective studies in other populations are needed to confirm or refute these results.

A prospective study of body size in different periods of life and risk of premenopausal breast cancer.

The prevalence of obesity at all ages is increasing epidemically worldwide. Information on the association between premenopausal breast cancer and body size during childhood and teenage years is scarce. In 1991 to 1992, a prospective cohort study was assembled in Norway and Sweden. We included in the analysis presented here 99,717 premenopausal women. During the follow-up period, which ended in December 1999, 733 of these women developed a primary invasive breast cancer. Overweight and obesity [body mass index (BMI) > 25 kg/m(2)] at enrollment was associated with a decreased risk of premenopausal breast cancer (P for linear trend = 0.007). Apparent associations between perceived body shape at age 7 and BMI at age 18, with heavier builds at both ages seemingly being protective for premenopausal breast cancer risk, lost their statistical significance after adjustment for BMI at cohort enrollment. Body size at age 7 was correlated with BMI at age 18 (r = 0.43); BMI at age 18 was correlated with adult BMI (r = 0.48). Changes in body size from age 7 or 18 to adulthood did not affect per se risk of premenopausal breast cancer risk. Height was related to risk, with a statistically significantly 30% reduced risk only in women shorter than 160 cm as compared with taller ones. The decreased risk of premenopausal breast cancer was observed in overweight and obese women without, but not in those with, a family history of breast cancer.

Empirically derived dietary patterns and risk of postmenopausal breast cancer in a large prospective cohort study.

BACKGROUND: Inconsistent associations have been reported between diet and breast cancer. OBJECTIVE: We prospectively examined the association between dietary patterns and postmenopausal breast cancer risk in a US-wide cohort study. DESIGN: Data were analyzed from 40 559 women who completed a self-administered 61-item Block food-frequency questionnaire in the Breast Cancer Detection Demonstration Project, 1987-1998; 1868 of those women developed breast cancer. Dietary patterns were defined by using principal components factor analysis. Cox proportional hazard regression was used to assess breast cancer risk. RESULTS: Three major dietary patterns emerged: vegetable-fish/poultry-fruit, beef/pork-starch, and traditional southern. The vegetable-fish/poultry-fruit pattern was associated with higher education than were the other patterns, but was similar in nutrient intake to the traditional southern pattern. After adjustment for confounders, there was no significant association between the vegetable-fish/poultry-fruit and beef/pork-starch patterns and breast cancer. The traditional southern pattern, however, was associated with a nonsignificantly reduced breast cancer risk among all cases (in situ and invasive) that was significant for invasive breast cancer (relative hazard = 0.78; 95% CI = 0.65, 0.95; P for trend = 0.003). This diet was also associated with a reduced risk in women without a family history of breast cancer (P = 0.05), who were underweight or normal weight [body mass index (in kg/m(2)) < 25; P = 0.02], or who had tumors positive for estrogen receptor (P = 0.01) or progesterone receptor (P = 0.003). Foods in the traditional southern pattern associated with reduced breast cancer risk were legumes, low mayonnaise-salad dressing intake, and possibly cabbage. CONCLUSIONS: The traditional southern diet or its components are associated with a reduced risk of invasive breast cancer in postmenopausal women.

Could antioxidant supplementation prevent pre-eclampsia?

Pre-eclampsia is a disorder characterised by pregnancy-induced hypertension and new-onset proteinuria occurring in the second half of pregnancy. Worldwide, approximately 2-3% of all pregnant women develop pre-eclampsia. The condition is a major cause of maternal and fetal morbidity and mortality. Abnormal placentation is an important predisposing factor for pre-eclampsia, while endothelial activation appears to be central to the pathophysiological changes, possibly indicative of a two-stage disorder characterised by reduced placental perfusion and a maternal syndrome. There is increasing evidence that pre-eclampsia is associated with both increased oxidative stress and reduced antioxidant defences, which has led to the hypothesis that oxidative stress may play an important role in the pathogenesis of pre-eclampsia, perhaps acting as the link in a two-stage model of pre-eclampsia. In support of this hypothesis a small, but important, preliminary study has shown a highly significant (P=0.02) reduction in the incidence of pre-eclampsia in women at risk who were taking a supplement of vitamins C and E from mid-pregnancy. Furthermore, these findings support the hypothesis that oxidative stress is at least partly responsible for the endothelial dysfunction of pre-eclampsia. Several larger multicentre trials are currently underway to evaluate the efficacy, safety and cost benefits of antioxidant supplementation during pregnancy for the prevention of pre-eclampsia in both low- and high-risk women, including women with diabetes. The results of these trials are awaited with interest.

High risk of breast carcinoma after irradiation of young women with Hodgkin's disease.

BACKGROUND: Treatment-associated second neoplasms have emerged as a major threat to the continued survival of patients cured of Hodgkin's disease. In this study, the authors investigated the risk of breast carcinoma in an irradiated Hodgkin's disease population. METHODS: One hundred and eleven women younger than 60 years presenting between 1964 and 1984 with Stage I and II Hodgkin's disease who received mantle irradiation were retrospectively analyzed and compared with an age specific population. Median follow-up was 18 years (range, 10-30 years), and the median age at initiation of therapy was 24 years. Kaplan-Meier actuarial risks, relative risks (RRs) (the ratio of the observed to the expected cases) with 95% confidence intervals (CIs), and the log rank test for trends were calculated. RESULTS: Fourteen women developed breast carcinoma: 8 of 33 patients younger than 20 years at the time of irradiation, 5 of 48 patients age 20 to 29 years, and 1 of 30 patients age 30 years or older. Actuarial calculation predicted a 34.0% (CI, 14.2-53.8) risk of breast carcinoma at 25 years after therapy for the youngest group, 22.3% (CI, 4.1-40.5) for the group of intermediate age, and 3.5% (CI, 0-10.1) for the oldest group. The RR of breast carcinoma was 56 (CI, 23.3-107) for those 19 years or younger at the time of treatment, 7.0 (CI, 2.3-16.4) for those age 20-29 years, and 0.9 (CI, 0-5.3) for those 30 years and older. Excluding 1 patient who was age 38 years at the time of irradiation, the remaining 13 breast carcinomas were tightly clustered in women irradiated between the ages of 14 through 25, and were detected in years 11 through 25 after treatment, with 7 occurring in years 15 through 18. CONCLUSIONS: Women younger than 30 years, particularly those younger than 20 years, who have received mantle irradiation for Hodgkin's disease require meticulous follow-up for breast carcinoma. The high incidence of breast carcinoma in this patient population should be considered when making treatment decisions in young women with early stage Hodgkin's disease.

Etiology and pathophysiology of gestational diabetes mellitus.

In pregnancy, several physiologic changes take place, the sum of which tends to reset the glucose homeostasis in the direction of diabetes. About 1-2% of all pregnant women develop an abnormal glucose tolerance in pregnancy, but most often glucose tolerance returns to normal postpartum. This condition is called gestational diabetes mellitus (GDM). The possibility that glucose tolerance deteriorates in pregnancy because of diabetes-like changes in the secretory function of the endocrine pancreas has been investigated in healthy controls and in normal-weight gestational diabetic subjects. The insulin responses to oral glucose and mixed meals are equally large in these two groups, but the insulin response per unit of glycemic stimulus is significantly lower in the gestational diabetic subjects than in the controls. Diabetes-like changes in glucagon secretion are not observed in either group. Insulin degradation is unaffected by human pregnancy and the proinsulin share of the total plasma insulin immunoreactivity does not increase in pregnancy. Insulin receptor binding to monocytes from normal pregnant women is increased in midpregnancy but is significantly decreased in late pregnancy. No difference in insulin binding (at tracer insulin concentration) to monocytes from healthy pregnant controls and gestational diabetic subjects is found. The insulin concentration necessary to reduce tracer insulin binding by 50% (ID50) is lower in the gestational diabetic subjects diagnosed in late pregnancy than in the pregnant controls. Together, these findings indicate that the number of insulin receptors on monocytes is decreased in GDM at this stage of pregnancy.(ABSTRACT TRUNCATED AT 250 WORDS)

Obstetric cholestasis: current opinions and management.

Obstetric cholestasis (OC) is a pregnancy-specific liver condition that typically presents with generalised pruritus in the absence of a rash in the late second trimester or third trimester. It is more common in certain ethnic groups, particularly those from South Asian, South American, Nordic and Scandinavian regions, and has a familial and genetic basis. Recent research suggests that the pathophysiology may reside in mutations in genes that code for bile acid transporter proteins. Mutations involving the bile acid transporters may impair maternal excretion and influence transplacental passage of bile acids. It is hypothesised that the surge in pregnancy steroid hormones may result in genetically predisposed women developing cholestasis. The condition is also associated with increased perinatal morbidity and mortality, particularly from preterm labour, fetal distress and intrauterine deaths. Animal studies have shown that bile acids are cardiotoxic, which may help explain the condition's association with fetal distress and stillbirths. Accurate diagnosis relies on a high index of suspicion, and the findings of abnormal liver function tests and raised serum bile acid levels after the exclusion of other organic causes of liver disease. Ursodeoxycholic acid helps relieve symptoms, improve serum bile acid levels and possibly has a cardioprotective effect. Active management, in the form of close antepartum fetal monitoring and delivery before 37 weeks, helps to decrease the risk of intrauterine deaths, though possibly at the expense of increased obstetric intervention. Following delivery, there is usually a dramatic improvement of symptoms and resolution of the condition. Women should be counselled about the high recurrence risk of OC in subsequent pregnancies.

Developing resilience: how women maintain their health in northern geographically isolated settings.

The purpose of this study was to explore how women maintain their health in northern geographically isolated settings, using a feminist grounded theory method. Twenty-five women of diverse backgrounds in northern British Columbia, Canada, engaged in qualitative interviews over a 2-year period to express perspectives about how the north affects their health and how they maintain their health in northern settings. Findings reveal that the women experienced vulnerability to physical health and safety risks, psychosocial health risks, and risks of inadequate health care. The women responded to these vulnerabilities by developing resilience through the strategies of becoming hardy, making the best of the north, and supplementing the north. These strategies, which reflect both individual and collective actions, were determined by the needs and interests of the women and their social and personal resources. The findings have implications for women's health research and health practices and policies in geographically isolated settings.

Women and bipolar disorder across the life span.

Bipolar I disorder occurs in approximately 1% of the adult population, and it affects women and men equally. Women develop bipolar II disorder, bipolar depression, mixed mania, and a rapid-cycling course of illness more commonly than men and are at greater risk of such comorbid conditions as alcohol use problems, thyroid disease, medication-induced obesity, and migraine headaches. The treatment of bipolar disorder remains challenging. Although lithium reduces symptoms and prevents recurrence with good efficacy, a significant number of patients stop taking it. Furthermore, several anticonvulsants and antidepressants are prescribed off label for acute episodes and prophylaxis despite the lack of adequate research support. Psychotherapy may alleviate mania or depression and improve treatment compliance, yet its ability to prevent relapse remains uncertain. Changes throughout the reproductive cycle also have an impact on the onset and presentation of bipolar symptoms and the choice of treatment. This article provides an overview of common presentations and comorbidities, along with approaches to evaluation and treatment of women with bipolar disorder.

Epidemiological aspects of heart failure.

Epidemiologic data based on general population surveillance examining the prevalence, incidence, and outlook of cardiac failure are sparse. The Framingham Study has followed a cohort representative of the general population biennially for three decades and provides such information. Four hundred eighty-five men and women developed first evidence of overt cardiac failure over 30 years. Between the ages of 35 to 64, the annual incidence of heart failure was 3 per 1000 and increased to 10 per 1000 at ages 65 to 94 years. There was a slight male predominance attributed to their greater propensity to coronary heart disease. Most cardiac failure was associated with long-standing hypertension or the presence of coronary heart disease. Risk of cardiac failure was increased two- to six-fold in persons with coronary heart disease; angina conferred half the risk of myocardial infarction. Silent or unrecognized infarctions predisposed equally as typically symptomatic ones; valvular deformity was a less common cause of cardiac failure. Cardiac failure proved to be an extremely lethal condition with a prognosis little better than cancer. The 6-year mortality rate was 82 per cent for men and 67 per cent for women corresponding to a death rate four- to eight-fold greater than that of persons the same age. Cardiovascular mortality was increased six- to nine-fold, stroke four- to seven-fold in men and women, respectively. Approximately 55 per cent of deaths in men and 73 per cent in women were due to cardiovascular causes, and 43 per cent and 44 per cent, respectively, to coronary disease. Sudden death was a common mode of exitus.(ABSTRACT TRUNCATED AT 250 WORDS)

Plasma sex hormone concentrations and subsequent risk of breast cancer among women using postmenopausal hormones.

BACKGROUND: Sex hormone concentrations are associated with breast cancer risk among women not using postmenopausal hormones (PMH); however, whether a relationship exists among PMH users is unknown. Therefore, we conducted a prospective, nested case-control study within the Nurses' Health Study (NHS) cohort to examine the association between plasma sex hormone concentrations and postmenopausal breast cancer among women using PMH at blood collection. METHODS: Blood samples were collected from 1989 to 1990. During follow-up through May 31, 2000, 446 women developed breast cancer and were matched by age, date and time of day of blood collection, and fasting status to 459 control subjects (PMH users) who did not develop cancer. We used conditional logistic regression to estimate relative risks (RRs) and 95% confidence intervals (CIs). We compared hormone concentrations of the 459 control subjects with those of 363 postmenopausal NHS participants not taking PMH. All statistical tests were two-sided. RESULTS: PMH users had statistically significantly higher estradiol, free estradiol, sex hormone-binding globulin, and testosterone, and lower free testosterone concentrations than non-PMH users. Among PMH users, we found modest associations with breast cancer risk when comparing the highest versus lowest quartiles of free estradiol (RR = 1.7, 95% CI = 1.1 to 2.7; P(trend) = .06), free testosterone (RR = 1.6, 95% CI = 1.1 to 2.4; P(trend) = .03), and sex hormone-binding globulin (RR = 0.7, 95% CI = 0.5 to 1.1; P(trend) = .04), but not of estradiol or of testosterone. However, estradiol and free estradiol were statistically significantly positively associated with breast cancer risk among women older than 60 years (RR = 2.8, 95% CI = 1.5 to 5.0; P(trend) = .002 and 2.6, 95% CI = 1.4 to 4.7; P(trend) = .001, respectively) and among women with a body mass index of less than 25 kg/m2 (RR = 1.8, 95% CI = 1.1 to 3.1, P(trend) = .01 and 2.4, 95% CI = 1.4 to 4.0, P(trend) = .003, respectively). CONCLUSION: Although women using PMH have a different hormonal profile than those not using PMH, plasma sex hormone concentrations appear to be associated with breast cancer risk among PMH users.

CHAMPS physical activity questionnaire for older adults: outcomes for interventions.

PURPOSE: To evaluate effectively interventions to increase physical activity among older persons, reliable and valid measures of physical activity are required that can also detect the expected types of physical activity changes in this population. This paper describes a self-report physical activity questionnaire for older men and women, developed to evaluate the outcomes of the Community Healthy Activities Model Program for Seniors (CHAMPS), an intervention to increase physical activity. METHODS: The questionnaire assesses weekly frequency and duration of various physical activities typically undertaken by older adults. We estimated caloric expenditure/wk expended in physical activity and created a summary frequency/wk measure. We calculated measures of each of these for: 1) activities of at least moderate intensity (MET value >/= 3.0); and 2) all specified physical activities, including those of light intensity. Six-month stability was estimated on participants not likely to change (assessment-only control group, physically active cohort). Several tests of construct validity were conducted, and sensitivity to change was analyzed based on response to the CHAMPS intervention. RESULTS: The sample (N = 249) comprised underactive persons (N = 173 from the CHAMPS trial) and active persons (N = 76). The sample was aged 65-90 yr (mean = 74, SD = 6); 64% were women, and 9% were minorities. Six-month stability ranged from 0.58 to 0.67, using intraclass correlation coefficients. Nearly all construct validity hypotheses were confirmed, though correlations were modest. All measures were sensitive to change (P < or = 0.01), with small to moderate effect sizes (0.38-0.64). CONCLUSIONS: The CHAMPS measure may be useful for evaluating the effectiveness of programs aimed at increasing levels of physical activity in older adults.

Striking differences in the epidemiological picture of breast cancer in urban and rural areas in Poland.

Poland is a European country of medium female breast cancer risk but a steady, mean incidence growth of 3.5% per year makes this cancer the most frequent malignancy and a leading cause of cancer-related deaths among the women of the 1980s. Our analysis is based on data collected by the Warsaw Cancer Registry in the years 1963-1987. The crude incidence rate in Poland doubled against 1963 and was nearly 40/100,000 in 1988. In 1988 eight thousand women developed breast cancer. In Poland, the incidence of 37.7 was higher in Warsaw than the rate of 16.6 obtained for Warsaw Rural Areas (WRA) in 1963. The trend continued until 1988 to reach 59.7 and 33.5 in the respective areas. Incidence rapidly grew with age, starting in the group of 30 to reach its peak of 149.2 at 65 and over in Warsaw and 86.6 in WRA. Mortality rates in Warsaw grew from 16.6 in 1963 to 30.7 in 1988 and, from 10.8 to 17.4 in WRA in the respective years. The urban/rural ratio declined from 1.7 to 1.5 during this period. The unfavourable proportion (patient distribution according to clinical staging in Warsaw was: 0 + I-17.2%; II-34.1%; III-29.1%; IV-23.6%. The relative 5-year survivals in Warsaw were 58.7% and they improved little compared to the former periods. These figures were even lower in WRA and they showed a downward trend for women aged over 65. A steady increase in breast cancer risk observed after 1963 and the large proportion of advanced breast cancers diagnosed, were followed by poor results of treatment causing about 5,000 breast cancer deaths in Poland annually.

First-trimester nuchal translucency screening in pregnant women who subsequently developed gestational diabetes.

OBJECTIVE: To compare the nuchal translucency (NT) thickness at 11-14 weeks of gestation in women who will later develop gestational diabetes mellitus (GDM) with that of women with normal glucose tolerance (NGT) in the second trimester of pregnancy. METHODS: Four hundred sixty-four women underwent NT screening at 11-14 weeks of gestation according to the standards of the Fetal Medicine Foundation. They all underwent an oral glucose tolerance test (OGTT) between 24 and 28 weeks. RESULTS: Women with GDM (n = 135) were significantly older (34.0 years [+/-4.8] vs 29.4 years [+/-5.2]; P < .001), had a significantly higher body mass index (BMI) (28.2 kg/m2 [+/-6.0] vs 24.4 [+/-5.0]; P < .001), and had a significantly higher serum concentration of hemoglobin A1c (HbA1c) at the time of the NT measurement (5.38% [+/-0.6] vs 4.95% [+/-0.4]; P < .001] than women with NGT (n = 329). There is no significant difference in the NT measurement at 11 to 14 weeks of gestation between women with GDM and NGT after correction for crown rump length (CRL) (r = -.08, P = .45). We performed multiple linear regression analysis with NT as the dependent variable, and BMI, maternal age, CRL, and GDM/NGT as independent variables. CRL (P < .001) was significantly related to the NT measurement, whereas GDM/NGT, BMI, and maternal age were not. CONCLUSION: As no significant difference in the NT measurement between women with GDM and NGT was observed, the risk estimation for chromosomal abnormality derived from the maternal age and NT measurement can also be used in women with glucose disorders.

The possible premalignant character of oral lichen planus and oral lichenoid lesions: a prospective five-year follow-up study of 192 patients.

Recently, we reported the preliminary results of a prospective study on the possible premalignant character of oral lichen planus (OLP) and oral lichenoid lesions (OLL). Based on these data it was concluded that there was some but no convincing support for the hypothesis that patients with OLL have an increased risk of development of oral cancer, but not so in patients with OLP. In the present treatise the results of prolonged follow-up of this cohort of patients have been described. A study group of 192 patients, 67 patients diagnosed with OLP and 125 patients with OLL, according to revised World Health Organization diagnostic criteria, was followed for periods ranging from 7.6 to 96.9 months (mean, 55.9 months). The expected number of patients with oral cancer in the group of patients with OLP and in the group of patients with OLL was estimated by comparing the number of patients, their ages, sex, and the length of follow-up to annual incidence rates of oral cancer for the general population in The Netherlands. The binomial test was used to determine whether the observed number of cases of cancer in the OLP group and the OLL group exceeded the expected numbers. Four out of 192 patients, two men and two women, developed a squamous cell carcinoma of the oral mucosa during follow-up. All malignant transformations occurred in the OLL group. The malignant transformation of the OLL group, based on a mean follow-up of 53.8 months, was calculated at 0.71% per year. A comparison of the expected against actual figures for the development of carcinomas revealed no increase in patients with OLP and a 142-fold increase in patients with OLL, the latter being statistically significant, with a p-value of 0.044. The present data give support to the hypothesis that patients with OLL have an increased risk of development of oral cancer. There seems to be no increased risk in patients with OLP. In view of our results we advise to monitor only the subgroup of OLL patients twice a year for early detection of possible malignant transformation.

Impact of the Higgins Nutrition Intervention Program on birth weight: a within-mother analysis.

A study was conducted to evaluate the impact of the Higgins Nutrition Intervention Program of individual nutritional assessment and rehabilitation on pregnancy outcome in a group of urban low-income women. Developed as an adjunct to routine prenatal care, the Higgins program utilizes an individualized approach to dietary treatment that combines an assessment of the risk profile for the presenting pregnancy with the application of specific nutritional rehabilitation allowances to compensate for the negative impact of diagnosed risks. This report presents results of analyses evaluating differences in birth outcomes between 552 sibling pairs; each mother had participated in the Higgins program during the pregnancy of the second-born, but not of the first-born, member of her pair. After adjustment for parity and sex, the intervention infants weighed an average of 107 gm more than their matched siblings at birth (p less than .01). The rate of low birth weight was 50% lower among the intervention infants than among their siblings (p less than .01); rates of intra-uterine growth retardation and perinatal mortality were also lower in the intervention group. The high risk of poor pregnancy outcome in this group of urban low-income women was reduced by the Higgins program.

Prenatal cocaine exposure. A longitudinal study of development.

The current study examines the effect of prenatal cocaine use on physical, cognitive, and behavioral development at birth, 1, 3, and 7 years, controlling for other factors that affect child development. Women who used cocaine during pregnancy were more likely to be single and to use alcohol, marijuana, and tobacco than were women who did not use cocaine. Prenatal cocaine use was associated with reduced gestational age, but not with birth weight, length, or head circumference. Neonatal neurobehavioral assessments were affected by prenatal cocaine exposure. Growth at 1 year was not affected by prenatal cocaine use. At 3 years, prenatal cocaine use was a significant predictor of head circumference and of the composite score on the Stanford-Binet Intelligence Scale (4th edition). Prenatal cocaine use was also associated with temperamental differences at 1 and 3 years and with behavior problems at 3 years. These findings represent a pattern of central nervous system effects, related to prenatal cocaine exposure, which is predicted by the teratologic model.
