RESUMEN

OBJECTIVE: Limited data are available from low- and middle-income countries (LMICs) on the relationship of haemoglobin levels to adverse outcomes at different times during pregnancy. We evaluated the association of haemoglobin levels in nulliparous women at two times in pregnancy with pregnancy outcomes. DESIGN: ASPIRIN Trial data were used to study the association between haemoglobin levels measured at 6+0 -13+6  weeks and 26+0 -30+0  weeks of gestation with fetal and neonatal outcomes. SETTING: Obstetric care facilities in Pakistan, India, Kenya, Zambia, The Democratic Republic of the Congo and Guatemala. POPULATION: A total of 11 976 pregnant women. METHODS: Generalised linear models were used to obtain adjusted relative risks and 95% CI for adverse outcomes. MAIN OUTCOME MEASURES: Preterm birth, stillbirth, neonatal death, small for gestational age (SGA) and birthweight <2500 g. RESULTS: The mean haemoglobin levels at 6+0 -13+6  weeks and at 26-30 weeks of gestation were 116 g/l (SD 17) and 107 g/l (SD 15), respectively. In general, pregnancy outcomes were better with increasing haemoglobin. At 6+0 -13+6  weeks of gestation, stillbirth, SGA and birthweight <2500 g, were significantly associated with haemoglobin of 70-89 g/l compared with haemoglobin of 110-129 g/l The relationships of adverse pregnancy outcomes with various haemoglobin levels were more marked at 26-30 weeks of gestation. CONCLUSIONS: Both lower and some higher haemoglobin concentrations are associated with adverse fetal and neonatal outcomes at 6+0 -13+6  weeks and at 26-30 weeks of gestation, although the relationship with low haemoglobin levels appears more consistent and generally stronger. TWEETABLE ABSTRACT: Both lower and some higher haemoglobin concentrations were associated with adverse fetal and neonatal outcomes at 6-13 weeks and 26-30 weeks of gestation.

RESUMEN

OBJECTIVE: To describe the association of maternal anaemia with maternal, fetal, and neonatal outcomes. DESIGN: Prospective cohort study. SETTING: Rural India and Pakistan. POPULATION: Pregnant women residing in the study catchment area. METHODS: We performed an analysis of a prospective pregnancy registry in which haemoglobin is commonly obtained as well as maternal, fetal, and neonatal outcomes for 42 days post-delivery. Women 40 years or older who delivered before 20 weeks or had a haemoglobin level of <3.0 g/dl were excluded. Our primary exposure was maternal anaemia, which was categorised in keeping with World Health Organization criteria based on a normal (≥11 g/dl), mild (>10-10.9 g/dl), moderate (7-9.9 g/dl) or severe (<7 g/dl). haemoglobin level. The primary maternal outcome was maternal death, the primary fetal outcome was stillbirth, and the primary neonatal outcome was neonatal mortality <28 days. RESULTS: A total of 92 247 deliveries and 93 107 infants were included, of which 87.8% were born to mothers who were anaemic (mild 37.9%, moderate 49.1%, and severe 0.7%). Maternal mortality (number per 100 000) was not associated with anaemia: normal 124, mild 106, moderate 135, and severe 325 (P = 0.64). Fetal and neonatal mortality was associated with severe anaemia: stillbirth rate (n/1000)-normal 27.7, mild 25.8, moderate 30.1, and severe 90.9; P < 0.0001; 28-day neonatal mortality (n/1000)-normal 24.7, mild 22.9, moderate 28.1, and severe 72.6 (P < 0.0001). Severe maternal anaemia was also associated with low birthweight (<2500 and <1500 g), preterm birth, and postpartum haemorrhage. CONCLUSION: Severe maternal anaemia is associated with higher risks of poor maternal, fetal, and neonatal outcomes but other degrees of anaemia are not. Interventions directed at preventing severe anaemia in pregnant women should be considered. TWEETABLE ABSTRACT: Severe maternal anaemia is associated with adverse fetal and neonatal outcomes in low/middle-income countries.

RESUMEN

OBJECTIVE: To determine whether oral clindamycin reduces the risk of preterm birth (PTB) in women with abnormal vaginal microflora as evidenced by a vaginal pH ≥5.0. DESIGN: Randomised double-blind placebo-controlled trial. SETTING: Rural southern India. POPULATION: Pregnant women with a singleton fetus between 13+0/7 weeks and 20+6/7 weeks. METHODS: Pregnant women were recruited during prenatal visits in Karnataka, India, from October 2013 to July 2015. Women were required to have a singleton fetus between 13+0/7 weeks and 20+6/7 weeks and an elevated vaginal pH (≥5.0) by colorimetric assessment. Participants were randomised to either oral clindamycin 300 mg twice daily for 5 days or an identical-appearing placebo. MAIN OUTCOME MEASURES: The primary outcome was the incidence of PTB, defined as delivery before 37+0/7 weeks. RESULTS: Of the 6476 screened women, 1727 women were randomised (block randomised in groups of six; clindamycin n = 866, placebo n = 861). The demographic, reproductive, and anthropomorphometric characteristics of the study groups were similar. Compliance was high, with over 94% of capsules being taken. The rate of PTB before 37 weeks was comparable between the two groups [clindamycin 115/826 (13.9%) versus placebo 111/806 (13.8%), between-group difference 0.2% (95% CI -3.2 to 3.5%, P = 0.93)], as was PTB at less than 34 weeks [clindamycin 40/826 (4.8%) versus placebo group 37/806 (4.6%), between-group difference 0.3% (95% CI -1.8 to 2.3%, P = 0.81)]. No differences were detected in the incidence of birthweight of<2500 g, <1500 g, miscarriage, stillbirth or neonatal death. CONCLUSION: In this setting, oral clindamycin did not decrease PTB among women with vaginal pH ≥5.0. TWEETABLE ABSTRACT: Oral clindamycin between 13+0/7 and 20+6/7 weeks does not prevent preterm birth in women with a vaginal pH ≥5.0.

RESUMEN

OBJECTIVE: To describe the causes of maternal death in a population-based cohort in six low- and middle-income countries using a standardised, hierarchical, algorithmic cause of death (COD) methodology. DESIGN: A population-based, prospective observational study. SETTING: Seven sites in six low- to middle-income countries including the Democratic Republic of the Congo (DRC), Guatemala, India (two sites), Kenya, Pakistan and Zambia. POPULATION: All deaths among pregnant women resident in the study sites from 2014 to December 2016. METHODS: For women who died, we used a standardised questionnaire to collect clinical data regarding maternal conditions present during pregnancy and delivery. These data were analysed using a computer-based algorithm to assign cause of maternal death based on the International Classification of Disease-Maternal Mortality system (trauma, termination of pregnancy-related, eclampsia, haemorrhage, pregnancy-related infection and medical conditions). We also compared the COD results to healthcare-provider-assigned maternal COD. MAIN OUTCOME MEASURES: Assigned causes of maternal mortality. RESULTS: Among 158 205 women, there were 221 maternal deaths. The most common algorithm-assigned maternal COD were obstetric haemorrhage (38.6%), pregnancy-related infection (26.4%) and pre-eclampsia/eclampsia (18.2%). Agreement between algorithm-assigned COD and COD assigned by healthcare providers ranged from 75% for haemorrhage to 25% for medical causes coincident to pregnancy. CONCLUSIONS: The major maternal COD in the Global Network sites were haemorrhage, pregnancy-related infection and pre-eclampsia/eclampsia. This system could allow public health programmes in low- and middle-income countries to generate transparent and comparable data for maternal COD across time or regions. TWEETABLE ABSTRACT: An algorithmic system for determining maternal cause of death in low-resource settings is described.

RESUMEN

OBJECTIVE: We sought to classify causes of stillbirth for six low-middle-income countries using a prospectively defined algorithm. DESIGN: Prospective, observational study. SETTING: Communities in India, Pakistan, Guatemala, Democratic Republic of Congo, Zambia and Kenya. POPULATION: Pregnant women residing in defined study regions. METHODS: Basic data regarding conditions present during pregnancy and delivery were collected. Using these data, a computer-based hierarchal algorithm assigned cause of stillbirth. Causes included birth trauma, congenital anomaly, infection, asphyxia, and preterm birth, based on existing cause of death classifications and included contributing maternal conditions. MAIN OUTCOME MEASURES: Primary cause of stillbirth. RESULTS: Of 109 911 women who were enrolled and delivered (99% of those screened in pregnancy), 2847 had a stillbirth (a rate of 27.2 per 1000 births). Asphyxia was the cause of 46.6% of the stillbirths, followed by infection (20.8%), congenital anomalies (8.4%) and prematurity (6.6%). Among those caused by asphyxia, 38% had prolonged or obstructed labour, 19% antepartum haemorrhage and 18% pre-eclampsia/eclampsia. About two-thirds (67.4%) of the stillbirths did not have signs of maceration. CONCLUSIONS: Our algorithm determined cause of stillbirth from basic data obtained from lay-health providers. The major cause of stillbirth was fetal asphyxia associated with prolonged or obstructed labour, pre-eclampsia and antepartum haemorrhage. In the African sites, infection also was an important contributor to stillbirth. Using this algorithm, we documented cause of stillbirth and its trends to inform public health programs, using consistency, transparency, and comparability across time or regions with minimal burden on the healthcare system. TWEETABLE ABSTRACT: Major causes of stillbirth are asphyxia, pre-eclampsia and haemorrhage. Infections are important in Africa.

RESUMEN

OBJECTIVE: Sublingual misoprostol produces a rapid peak concentration, and is more effective than oral administration. We compared the postpartum measured blood loss with 400 µg powdered sublingual misoprostol and after standard care using 10 iu intramuscular (IM) oxytocin. DESIGN: Double-blind randomised controlled trial. SETTING: A teaching hospital: J N Medical College, Belgaum, India. SAMPLE: A cohort of 652 consenting eligible pregnant women admitted to the labour room. METHODS: Subjects were assigned to receive the study medications and placebos within 1 minute of clamping and cutting the cord by computer-generated randomisation. Chi-square and bootstrapped Student's t-tests were used to test categorical and continuous outcomes, respectively. MAIN OUTCOME MEASURES: Measured mean postpartum blood loss and haemorrhage (PPH, loss ≥ 500 ml), >10% pre- to post-partum decline in haemoglobin, and reported side effects. RESULTS: The mean blood loss with sublingual misoprostol was 192 ± 124 ml (n=321) and 366 ± 136 ml with oxytocin IM (n=331, P ≤ 0.001). The incidence of PPH was 3.1% with misoprostol and 9.1% with oxytocin (P=0.002). No woman lost ≥ 1000 ml of blood. We observed that 9.7% and 45.6% of women experienced a haemoglobin decline of >10% after receiving misoprostol and oxytocin, respectively (P ≤ 0.001). Side effects were significantly greater in the misoprostol group than in the oxytocin group. CONCLUSION: Unlike other studies, this trial found sublingual misoprostol more effective than intramuscular oxytocin in reducing PPH, with only transient side effects being greater in the misoprostol group. The sublingual mode and/or powdered formulation may increase the effectiveness of misoprostol, and render it superior to injectable oxytocin for the prevention of PPH. Further research is needed to confirm these results.

RESUMEN

Pharmacologic osteoporosis therapy, particularly anti-resorptives, is recommended in postmenopausal women with clinical risk factors for fracture. Treatment decisions should be made based on the relative benefit-risk profile in different patient populations. Emerging options [e.g., selective estrogen receptor modulators (SERMs) and denosumab] may hold promise for providing protection from bone loss and for fracture risk reduction.Osteoporosis, the most common clinical disorder of bone metabolism, is characterized by low bone mineral density, deterioration of microarchitecture, and a consequent increase in bone fragility and risk of fracture. Pharmacologic therapy is recommended in postmenopausal women with clinical risk factors for fracture and includes anti-resorptive agents such as bisphosphonates, hormone therapy, SERMs, and calcitonin. The anabolic agent teriparatide (parathyroid hormone) is usually reserved for high-risk patients or those with glucocorticoid-induced osteoporosis. Strontium ranelate, available outside the USA, has both anti-resorptive and anabolic properties. Supplementation with calcium and vitamin D is recommended for all women aged 50 years and older. Bisphosphonates are often considered first-line therapy for osteoporosis and have the largest base of clinical trial data showing efficacy for global fracture risk reduction. Low-dose hormone therapy is appropriate for younger women who are experiencing other menopausal symptoms. In women for whom bisphosphonates are not appropriate or not tolerated or in younger postmenopausal women who have a low risk for hip fracture, SERMs are a suitable treatment option. Calcitonin is designated for patients who are unable or unwilling to tolerate other osteoporosis agents. Emerging options, including newer SERMs (e.g., bazedoxifene and lasofoxifene) and the monoclonal antibody denosumab, may hold promise for providing protection from bone loss and for fracture risk reduction. Because no single agent is appropriate for all patients, treatment decisions should be made on an individual basis, taking into account the relative benefits and risks in different patient populations.

RESUMEN

Despite the strong interest of international health agencies, worldwide maternal mortality has not declined substantially over the past 10 years. Postpartum hemorrhage (PPH) is the most common cause of maternal death across the world, responsible for more than 25% of deaths annually. Although effective tools for prevention and treatment of PPH are available, most are not feasible or practical for use in the developing world where many births still occur at home with untrained birth attendants. Application of many available clinical solutions in rural areas would necessitate substantial changes in government infrastructure and in local culture and customs surrounding pregnancy and childbirth. Before treatment can be administered, prompt and accurate diagnosis must be made, which requires training and appropriate blood measurement tools. After diagnosis, appropriate interventions that can be applied in remote settings are needed. Many uterotonics known to be effective in reducing PPH in tertiary care settings may not be useful in community settings because they require refrigeration and/or skilled administration. Moreover, rapid transfer to a higher level of care must be available, a challenge in many settings because of distance and lack of transportation. In light of these barriers, low-technological replacements for treatments commonly applied in the developed-world must be utilized. Community education, improvements to emergency care systems, training for birth attendants, misoprostol, and Uniject have shown promise as potential solutions. In the short term, it is expedient to capitalize on practical opportunities that utilize the existing strengths and resources in each community or region in order to implement appropriate solutions to save the lives of women during childbirth.

RESUMEN

OBJECTIVE: To compare (1) visual estimation of postpartum blood loss with estimation using a specifically designed blood collection drape and (2) the drape estimate with a measurement of blood loss by photospectrometry. METHODS: A randomized controlled study was performed with 123 women delivered at the District Hospital, Belgaum, India. The women were randomized to visual or drape estimation of blood loss. A subsample of 10 drape estimates was compared with photospectrometry results. RESULTS: The visual estimate of blood loss was 33% less than the drape estimate. The interclass correlation of the drape estimate to photospectrometry measurement was 0.92. CONCLUSION: Drape estimation of blood loss is more accurate than visual estimation and may have particular utility in the developing world. Prompt detection of postpartum hemorrhage may reduce maternal morbidity and mortality in low-resource settings.

RESUMEN

Long-term chlorpromazine therapy has been associated with the asymptomatic development of a high incidence of antinuclear antibodies, coagulation inhibitors, and increased serum levels of IgM. The purpose of this study has been to characterize the natural history of this chlorpromazine-induced (CPZ) immunopathy. To this end we carried out a prospective study of schizophrenic patients with the immunopathy to compare the effect of continuing CPZ versus switching to haloperidol therapy. Although no marked differences were noted between the 2 groups at the end of 5 years, 6 of 29 patients who continued to receive CPZ, as compared to none of 14 patients on haloperidol, had progressive elevations of serum IgM. In spite of a high incidence of antinuclear antibodies, none of the patients developed a lupus-like syndrome. One patient, however, who had been maintained on CPZ for more than 15 years, developed Waldenström macroglobulinemia, as characterized by an IgM monoclonal gammopathy and a lymphocyte immunoglobulin heavy and kappa light chain gene rearrangement. Another CPZ-treated patient developed immune thrombocytopenia. Based on the potential serious sequelae of prolonged stimulation of the immune system by CPZ, we recommend that patients who develop an increase in serum IgM while on CPZ be switched to other types of anti-psychotic medications.

RESUMEN

Androgen excess in women is manifested typically by clinical features that may include hirsutism, acne, central obesity, male-pattern baldness, upper torso widening, increased waist-to-hip ratio, clitoral hypertrophy, and deepening of the voice. The differential diagnosis includes androgen-producing ovarian and adrenal neoplasms, Cushing's syndrome, polycystic ovary syndrome, and the intake of exogenous androgens. Physicians treating patients for one symptom of androgen excess must be alert for other symptoms and signs. The cosmetic manifestations of androgen excess belie the serious health risks associated with this condition, including cardiovascular disease, intravascular thrombosis, and insulin resistance. Prompt clinical recognition of androgen excess, understanding of the androgen-related biochemical abnormalities underlying the risks associated with this condition, and implementation of risk modification can reduce the incidence of associated morbidity and mortality. An interdisciplinary approach to management is strongly recommended. Risk reduction strategies include correction of dyslipidemias, low-dose aspirin for primary prevention of myocardial infarction, maintenance of ideal weight, smoking cessation, exercise, use of oral contraceptives containing a low-androgenic progestin, and postmenopausal estrogen replacement. Combination oral contraceptives containing low-androgenic progestins are effective not only in reducing signs of androgen excess but also in potentially retarding the progression of long-term sequelae such as cardiovascular disease.


PIP: 5-10% of all women have an androgen excess syndrome. Androgen excess signs and symptoms include hirsutism, acne, central obesity, male-pattern baldness, upper torso widening, increased waist-to-hip ratio, clitoral hypertrophy, and deepening of the voice. Physicians must be able to recognize these signs and symptoms. Presence of these signs and symptoms calls for a screening history and physical examination. Differential diagnoses of androgen excess in women include endogenous and exogenous causes. Endogenous-related diagnoses are those of ovarian origin (primary tumors, metastatic tumors, polycystic ovary syndrome, ovarian stromal hyperthecosis, androgen excess in pregnancy, and abnormal gonadal or sexual development) and those of adrenal origin (Cushing's syndrome/disease, late-onset congenital adrenal hyperplasia, and tumors). Exogenous causes of androgen excess include Danazol, Phenytoin, Diazoxide, Hexachlorobenzene, Hexachlorophene, Minoxidil, Cyclosporin, testosterone and other androgens, anabolic steroids, synthetic progestins (the pill), and Metapyrone. When physicians treat patients for one symptom of androgen excess, they should watch for other signs and symptoms. Serious health risks associated with androgen excess include cardiovascular disease, intravascular thrombosis, and insulin resistance. Physicians must be aware that timely clinical recognition of androgen excess, knowledge of androgen-related biochemical abnormalities underlying the risks linked to androgen excess, and risk modification behavior reduces associated morbidity and mortality. Risk reduction strategies are correction of dyslipidemias, low-dose aspirin for primary prevention of myocardial infarction, maintenance of ideal weight, smoking cessation, exercise, use of combined oral contraceptives (OCs) with a low-androgenic progestin, and postmenopausal estrogen replacement. OCs also slow progression of long-term sequelae (e.g., cardiovascular disease).

RESUMEN

Erythrocyte membrane Ca++ ATPase levels were investigated in 10 men treated with lithium carbonate for bipolar affective disorder. With regard to Ca++ ATPase activity, which is intimately associated with the active Ca++ transport mechanism of the red cell membrane, it is interesting to note that the Ca++ ATPase activities of bipolar disorder patients were found to be depressed at 2 hours after the administration of lithium. These data are discussed in terms of the physiology of bipolar affective disorder and lithium carbonate.

RESUMEN

Cardiovascular risks attributable to oral contraceptive use may now be subdivided into those that appear to be secondary to the estrogen component, i.e., venous thrombosis, pulmonary embolism, and those linked to the progestin component, i.e., small vessel disease including myocardial infarction and cerebrovascular accident. It appears that venous risk is attributable to subtle changes in clotting factors, while arterial risk may be secondary to changes in glucose and lipid metabolism. In order to determine which women are at greatest risk from oral contraceptive use, Spellacy et al. has developed a risk scoring form that aids in the screening process. After excluding women with an absolute contraindication to pill use, women at greatest risk for cardiovascular disease related to oral contraceptive use are those with a family history of hyperlipidemia, gestational or overt diabetics, hypertensives, and smokers over the age of 35. The gradual reduction by manufacturers of the steroid content of oral contraceptives appears to have lessened the incidence of adverse effects. Our current knowledge of risk factors permits the clinician to reduce exposure to oral contraceptive-related mortality by as much as 86 per cent. As we continue to search for ways to reduce risk among oral contraceptive users, it is important to note that more than 25 per cent of women are still taking formulations containing 50 micrograms of estrogen. It becomes the responsibility of the practicing physician to "step-down" these patients to lower-dose preparations such as the multiphasics. Such preparations also represent optimal therapy for first-time pill users.


PIP: The risks and benefits of the newer oral contraceptives are evaluated, considering cancer, teratogenicity, drug interactions, cardiovascular risks, and carbohydrate metabolism. Oral contraceptives confer the lowest mortality risk of all contraceptives, except sexual abstinence, in all women under 30 and in nonsmokers through age 40 in developed countries. In less developed countries where maternal mortality can be as high as 5-10%, the risks of even nonmedically supervised oral contraceptives are dwarfed. The pill protects against ovarian cancer even after the pill is discontinued because it suppresses ovulation, and endometrial cancer because it blocks estrogen receptors. The relationship of oral contraception to breast cancer is still in dispute, but no good evidence exists for increased risk, especially with new low- dose pills. There may be a slightly increased risk of cervical cancer, although it is difficult to separate out other risk factors co-existing in pill users, such as earlier sexarche, more partners and more frequent screening. The incidence of pelvic inflammatory disease, functional ovarian cysts and ectopic pregnancy is reduced by pills. There is only 1 report of increased incidence of congenital heart disease in infants whose mothers took pills during pregnancy. Drug interactions are common, and must be managed by the physician. Among currently popular pills, only the norgestrel and levonorgestrel-containing multiphasic pills are said to decrease HDL2 and impair glucose tolerance, because they are androgenic enough to overcome the low dose of estrogen.

RESUMEN

Despite the problems associated with coitus-dependent methods of contraception, barrier methods have an important role. The fact that they work as contraceptives without systemic effects makes them particularly appropriate for women with medical conditions that prevent the use of hormonal contraception. In addition, condoms and perhaps all barrier methods provide protection from sexually transmitted infections, making them essential for sexually active women at risk for STDs. Their continued importance is evidenced by the ongoing research to develop and improve barrier methods of contraception.

RESUMEN

A 34-year-old primigravida underwent genetic amniocentesis at 20 weeks gestation and the fetus was diagnosed as having Turner's syndrome. The concentration of alpha-fetoprotein in amniotic fluid was greatly elevated. Normal concentrations of amniotic fluid total protein, albumin and immunoglobulin indicated that the elevated level of alpha-fetoprotein was not the result of leakage through a hygroma, which has been previously suggested without supporting data in cases of Turner's syndrome of the fetus.

RESUMEN

International research partnerships bring together some of the best and the brightest in an effort to tackle global health problems. Such collaborations also pose complex challenges, such as maintaining ethical principles in the conduct of research in developing nations. In implementing a randomized clinical trial to reduce postpartum hemorrhage (PPH) during childbirth in rural India, U.S. and Indian collaborators addressed three such issues: the appropriateness of an ethical randomized controlled trial in the developing world, the inclusion of a placebo arm, and the relevance of informed consent in a semiliterate rural population.

RESUMEN

Use of oral contraceptives has been shown to reduce the risk of gynecologic conditions that cause significant mortality, including ovarian cancer, endometrial cancer and ectopic pregnancy. Additionally, its use has been linked to quality-of-life issues, such as the prevention of pelvic inflammatory disease, benign breast disease and functional ovarian cysts, as well as to dysmenorrhea, premenstrual syndrome and iron deficiency anemia. Such information should be conveyed to women of reproductive age during their contraceptive counseling session.

RESUMEN

Clinicians are increasingly faced with the task of counseling herpes genitalis patients. Excessive and exaggerated media coverage has caused a heightened emotional response to the initial diagnosis in many patients. Stages of disease coping occur. Stress reduction and positive coping mechanisms are important aspects of counseling these patients.

RESUMEN

The purpose of this work was to develop and conduct a needs and risk instrument to assess knowledge of osteoporosis risk factors, identify beliefs and attitudes about this disease, and delineate the presence and/or absence of healthy behaviors associated with osteoporosis among African American and Hispanic women. The survey findings suggest that African-American and Hispanic women are not well-versed in behaviors that would promote and maintain optimal bone mass. Consequently, they are not practicing appropriate lifestyle and dietary habits to decrease their risk of osteoporosis. Such behaviors include inadequate physical activity, inadequate calcium intake, cigarette smoking, and long-term steroid use. Less than 10% of women in the study were getting adequate daily dietary calcium intake, with only 13% taking daily calcium supplements to augment this deficit and less than one-half of women exercising at a minimal level (20 minutes/3 times a week). Women in this study also had limited knowledge about osteoporosis, perceived this condition to be less of a health threat as compared to breast cancer, heart disease, diabetes, and Alzheimer's disease, and very few had the perception that being Hispanic or African American was a factor to consider in assessing their risk of osteoporosis. Our findings suggest that osteoporosis education and prevention initiatives are needed, specifically for African-American and Hispanic women, to promote healthy behaviors, identify women at-risk, and encourage early diagnosis and treatment.
