Mobile Application Measurement of Menstrual Cycle Characteristics and Their Association with Dysmenorrhea and Activity Limitation in Early Adolescents. J Pediatr Adolesc Gynecol 2024; 37:126-131. [PMID: 37863175 PMCID: PMC11253899 DOI: 10.1016/j.jpag.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 09/21/2023] [Accepted: 10/12/2023] [Indexed: 10/22/2023]
Abstract
OBJECTIVE Real-time tracking of menstrual bleeding is a barrier to research due to limitations with traditional data collection tools. This prospective cohort study utilized a mobile application (TDot app) in young adolescents aged 10-14 years to assess the relationship between heavy menstrual bleeding (HMB), dysmenorrhea, and activity limitation. METHODS Menstrual cycles were captured over six months in real-time using the Pictorial Blood loss Assessment Chart (PBAC). A median PBAC score of >100 was used to identify participants with HMB. Participants also completed a modified WaLIDD (Working ability, Location, Intensity, Days of pain, Dysmenorrhea) scale. Impact of menses on daily activities was collected for each cycle. RESULTS A total of 160 participants enrolled and 100 (63%) participants with ≥3 cycles recorded in the mobile app were analyzed. HMB was noted in 41% of participants. Median modified WaLIDD score was significantly higher in participants with HMB than those without HMB (p=0.01). No significant differences were found in activity limitations between participants with and without HMB (p=0.34). Median modified WaLIDD score for participants with activity limitation was significantly higher than those without activity limitation (p=0.01). CONCLUSION Utilizing mobile app technology, we were able to gather real-time menstrual outcome data from young adolescents on heaviness of flow, dysmenorrhea and activity limitations. While we did not find that patients with HMB were more likely to have activity limitations, we did find that those with limitations had modestly higher dysmenorrhea scores. Future studies should focus on identifying additional variables that impact activity limitation during menstruation.

J Pediatr Adolesc Gynecol 2024; 37:106-120. [PMID: 38104798 DOI: 10.1016/j.jpag.2023.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 11/27/2023] [Accepted: 11/30/2023] [Indexed: 12/19/2023]
Abstract
STUDY OBJECTIVE The aim of this review was to create an overview of available instruments used to evaluate the menstrual complaints of dysmenorrhea and heavy menstrual bleeding (HMB) in adolescents. METHODS The search was conducted in PubMed, Web of Science, Embase, and PsycINFO on December 1, 2022. Studies published in English reporting on menstrual complaints among girls aged 10-19 were included. The quality and bias risk was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2. RESULTS Of 8994 identified studies, 57 were included. In these studies, 19 instruments were described, of which 8 were validated in adolescents. One was difficult to use in daily practice, 1 had low sensitivity and specificity in the detection of HMB, 2 were validated by face validity, and 2 were not specifically developed to evaluate (the impact of) menstrual complaints. Therefore, only 2 were validated and feasible to measure adolescent menstrual complaints: the Period ImPact and Pain Assessment (PIPPA) and the Adolescent Menstrual Bleeding Questionnaire (aMBQ). Remarkably, the Pictorial Blood Loss Assessment Chart (PBAC) was the most frequently used instrument in adolescents. There was one modified version of the PBAC for adolescents, which had a lower cutoff value for HMB and low sensitivity and specificity. CONCLUSION We found that the PIPPA and aMBQ are suitable for assessing menstrual complaints and their impact on daily activities and health-related quality of life in adolescents. The PBAC, which is used frequently in adults, needs to be further assessed specifically for adolescents. In particular, the clinical relevance of the PBAC cutoff value for HMB should be determined for this age group. Considering the different interpretations, experiences, and limited knowledge of menstrual complaints, instruments suitable for adults may not be suitable for adolescents.

The Association Between Hormonal Contraceptive Use and Anemia Among Adolescent Girls and Young Women: An Analysis of Data From 51 Low- and Middle-Income Countries. J Adolesc Health 2024; 74:563-572. [PMID: 37978956 PMCID: PMC11239219 DOI: 10.1016/j.jadohealth.2023.09.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 09/05/2023] [Accepted: 09/08/2023] [Indexed: 11/19/2023]
Abstract
PURPOSE This study explores whether adolescent girls and young women aged 15-24 who use hormonal methods of contraception are more or less likely to be anemic than their peers. We further examine whether the association between anemia and hormonal contraception varies based on the severity of anemia or the duration of method use. METHODS We conducted secondary analysis of data available for 51 low- and middle-income countries from the Demographic and Health Surveys. For each country, we used logistic regression models to explore the odds of being anemic (mildly, moderately, or severely) for those using hormonal methods of contraception. We also explored the odds of being moderately or severely anemic based on hormonal method use. Drawing on country-level effect estimates, we conducted meta-regression analyses to produce overall estimates of the association between anemia and hormonal contraception. RESULTS Overall, adolescent girls and young women using hormonal methods had lower odds of being mildly, moderately, or severely anemic (adjusted odds ratio 0.68; p < .001) and lower odds of being moderately or severely anemic (adjusted odds ratio 0.57; p < .001) compared to those not using any contraception. Both short- and long-term users of hormonal methods had lower odds of being anemic and lower odds of being moderately or severely anemic compared to those not using hormonal methods. DISCUSSION This study furthers our understanding of the association between anemia and use of hormonal contraception among adolescent girls and young women. More research is needed to assess causality and whether hormonal methods mediate the effects of heavy menstrual bleeding or other risk factors of anemia.

Roberts I, Brenner A, Shakur-Still H. Tranexamic acid for bleeding: Much more than a treatment for postpartum hemorrhage. Am J Obstet Gynecol MFM 2023; 5:100722. [PMID: 35988879 DOI: 10.1016/j.ajogmf.2022.100722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 08/01/2022] [Accepted: 08/13/2022] [Indexed: 10/15/2022]
Abstract
The evidence that early tranexamic acid treatment reduces postpartum hemorrhage deaths has major implications for obstetrical care worldwide. Tranexamic acid may also have a role in the prevention of postpartum hemorrhage, but more evidence is needed on the balance of risks and benefits. Most deaths from postpartum hemorrhage are in low- and middle-income countries where tranexamic acid treatment is often unavailable. Several maternal health organizations including the Reproductive Health Supplies Coalition, Clinton Health Access Initiative, Concept Foundation, International Federation of Gynecology and Obstetrics, and Unitaid are working to increase access. However, a wider view of the evidence on tranexamic acid and bleeding shows that it can improve maternal health in many other ways. An appreciation of these other health benefits could facilitate efforts to increase access. By reducing heavy menstrual bleeding, tranexamic acid could reduce the prevalence of maternal anemia, a common and important risk factor for postpartum hemorrhage and other maternal and neonatal outcomes. Further clinical trials of tranexamic acid for the treatment of menstrual bleeding are needed. By reducing surgical bleeding and the need for blood transfusion, tranexamic acid would increase the availability of blood in countries where there is blood shortage so that more blood is available for use in life-threatening bleeding including postpartum hemorrhage. In countries where there is no blood shortage, tranexamic acid use would reduce healthcare costs and prevent transfusion-transmitted infections and reactions. Trauma affects women and men, and violence is a leading cause of death in pregnancy. Increased use of tranexamic acid in trauma would significantly reduce trauma deaths. Efforts to increase the availability and use of tranexamic acid for obstetrical hemorrhage should acknowledge its other health benefits and aim to increase its use across health services more generally.

Magnitude and associated factors of anemia among adolescent girls in Ethiopia: a systematic review and meta-analysis. Arch Public Health 2022; 80:189. [PMID: 35953868 PMCID: PMC9373363 DOI: 10.1186/s13690-022-00942-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Accepted: 07/24/2022] [Indexed: 11/22/2022] Open
Abstract
Background In Ethiopia, there are primary studies on adolescent anemia with imprecise and inconclusive findings. Besides, there was no meta-analysis pooled the magnitude and associated factors of anemia among adolescent girls in Ethiopia. Estimating the pooled magnitude and associated factors of anemia among adolescent girls is helpful for evidence-based interventions in Ethiopia. Methods The authors used a preferred reporting item for systematic reviews and meta-analysis (PRISMA). We included articles and survey reports published until May 2021 using searching engines of Google, Google Scholar, PubMed, Scopus, and Cumulative Index to Nursing and Allied Health Literature. To assess the quality of studies, we used Newcastle–Ottawa quality assessment scale for non-randomized. Two authors independently assessed the quality of the studies. We computed the pool magnitude and odds ratio of the associated factors with their 95%CI using Comprehensive Meta-Analysis software. Publication bias assessed using funnel plots and Egger’s test. Result In this review, we included a total of 15 studies with 9,669 adolescent girls. Using the random-effects model, the pooled magnitude of anemia among the Ethiopian adolescent girls was 19.1% (95%CI: 16.1%, 24.6%). The associated factors were attained menarche (adjusted odds ratio (AOR) = 1.96), ≥ 5 days of blood flow during menses (AOR = 6.21), food insecurity (AOR = 1.48), inadequate diet diversity score (AOR = 2.81), presence of intestinal parasite (AOR = 3.51), low body mass index (AOR = 2.49), and rural residence (AOR = 1.79). Conclusion The pooled magnitude of anemia among adolescent girls in Ethiopia was 19.1% depicting a mild public health problem; while attained menarche, ≥ 5 days’ blood flow during menses, food insecurity, inadequate diet diversity score, intestinal parasites, low body mass index, and rural residence were the associated factors. Hence, addressing health and nutrition wellness of adolescent girls should be center of concern in health, nutrition, agriculture, research, strategies and policies in Ethiopia.

Abstract
BACKGROUND Anemia is a public health problem among adolescents in Indonesia. Strategies to prevent or treat anemia should be tailored to local conditions, taking into account its specific etiology and prevalence in a given setting and population group. OBJECTIVE This review aims to (1) identify and synthesize the current knowledge on the etiology of anemia among adolescents in Indonesia, (2) reveal knowledge gaps in this area, and (3) suggest directions for future research and programmatic work. METHODS We systematically searched PubMed, Web of Science, Scopus, Medline, and WorldCat databases for peer-reviewed journal articles to identify which etiological factors were related to anemia among Indonesian adolescents. Research papers were reviewed and included in the review according to inclusion criteria. RESULTS Of 13 studies, 8 showed that anemia was associated with iron deficiency; 4 are suggestive of vitamin A deficiency; and 2 of folic acid deficiency. Five studies underscore different etiological determinants for anemia, such as malaria, protein and energy malnutrition, vitamin B2 deficiency, calcium, and vitamin C deficiency. Based on these findings, we developed a framework on knowledge gaps on the etiology of anemia among adolescents in Indonesia, divided in 3 levels of knowledge: (1) significant knowledge gaps, (2) knowledge gaps, and (3) established knowledge. CONCLUSIONS The knowledge gaps around the etiology of anemia among Indonesian adolescents are significant. Our framework emphasizes the need for further research across all etiological factors, namely inadequate nutritional intake and absorption, genetic hemoglobin disorders, infection and inflammation, and menstrual disorders.

Abstract
AIM The aim of this evidence implementation project is to make a contribution to promoting evidence-based practice in the assessment and management of women with heavy menstrual bleeding (HMB) attending the gynaecology outpatient clinic at Kenyatta National Hospital (KNH) and thereby improve patient outcomes and resource utilization. METHODS The evidence implementation project was carried out at the gynaecology outpatient clinic of the largest referral facility in Kenya. The Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice audit and feedback tool were used. A baseline audit was conducted using a sample of 40 patient files; this was followed by interventions such as trainings, developing of visual tools and updating of protocols. A follow-up audit was then conducted 4 months post intervention. RESULTS Baseline audit results demonstrated varying results in each of the nine criteria selected. Four of the criteria recorded less than 51% compliance, with two of these recording 0% compliance. Postintervention results showed a remarkable increase in most of the audit criteria selected, with eight of these having compliance levels of 90% or more. CONCLUSION The implementation project served the dual purpose of enlightening health care workers on best practices and educating patients on what they need to know about their condition. This led to an overall improvement in the management of HMB.

Abstract
Societal determinants of health are of recognized importance for understanding the causal association of society and health of an individual. Iron deficiency anemia (IDA) is a challenging public health problem across the globe instigating from a broader sociocultural background. It is more prevalent among pregnant women, children under the age of five years, and adolescent girls. Adolescent girls are vulnerable to develop IDA because of additional nutritional demand of the body needed for growth spurt, blood loss due to onset of menarche, malnourishment, and poor dietary iron intake. In this study, we explore the societal determinants of anemia among adolescent girls in Azad Jammu and Kashmir (AJK), Pakistan. A cross-sectional study was conducted in the Muzaffarabad division of AJK on randomly selected 626 adolescent girls. The data were collected using a pretested self-administered interview schedule comprising mainly closed-ended questions with a few open-ended questions. Descriptive statistics was computed for describing the data, and bivariate regression and logistic regression were used to determine the association of anemia with its societal determinants. Multiple linear regression is used to determine the relationship of different determinants (independent variables) with the hemoglobin level (dependent variable) of the respondents. The prevalence of anemia among adolescent girls is 47.9%, of which 47.7% have mild anemia, 51.7% have moderate anemia, and 5.7% have severe anemia, which reveals that anemia is a severe public health problem among adolescent girls in the study area. The findings aver that anemia occurrence was significantly associated with the respondent's and her parental education, economic well-being, prevalence of communicable diseases, menstrual disorder, exercise habits, meals regularity, and type of sewerage system.

Abstract
The aim of this study was to investigate the relationship between stature and menstrual pattern. Nine hundred and seventy six girls were selected from regions within two cities in north-eastern Iran in 2015. They were assessed with respect to: their stature and menstrual pattern, age of menstruation, severity of dysmenorrhoea, duration of their menstrual cycle and flow. 841 girls had experienced menarche. 10.5% had a short stature. There were significant differences in age, height, weight and body mass index between those who had experienced their first menstrual cycle and others (p < .001). There were weak and negative correlation between age of menarche and height percentiles (r = -0.12, p < .001). Premenstrual syndrome, duration of menstruation cycle and bleeding period did not differ between these two groups (p > .05). We found that dysmenorrhoea was significantly influenced by height. Although the mean age at menarche was statistically significant among different statures, the range was narrow (12.2-12.7). Further studies considering environmental factors, including socioeconomic status and nutrition concurrently, are also required.Impact statementWhat is already known on this subject? Various menstrual characteristics, including age of menarche, severity of dysmenorrhoea and duration of menstrual period may be associated with height. But, there have been few studies on the relationship between short stature and its impact on health status and menstrual patterns in adolescents.What do the results of this study add? There were significant differences in age, height, weight and body mass index between adolescent girls who had experienced their first menstrual cycle, and others. There were weak, negative, significant correlations between age of menarche and height percentiles. Dysmenorrhoea was significantly influenced by height.What are the implications of these findings for clinical practice and/or further research? Life style modification and nutritional interventions that optimise the height of girls may resolve their menstrual problems and dysmenorrhoea.

Abstract
STUDY OBJECTIVE On this study we sought to determine the relationship of bleeding disorders to iron deficiency anemia. Additionally, this study was undertaken to examine all current treatment modalities used in a menorrhagia clinic with respect to heavy menstrual bleeding management to identify the most effective options for menstrual management in the setting of an underlying bleeding disorder. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We performed a retrospective chart review of adolescents younger than 21 years with heavy menstrual bleeding attending a multidisciplinary hematology-adolescent gynecology clinic. Information including demographic characteristics, bleeding diathesis, hematologic parameters, treatment, and the diagnosis was extracted from each chart. Subjects were grouped into 2 categories on the basis of the diagnosis of a bleeding disorder. Hemoglobin level, iron deficiency anemia, and need for transfusion were compared between a bleeding disorder and no bleeding disorder group. Subjects were grouped into categories depending on hormonal modality and treatment success of the groups were compared. RESULTS Seventy-three subjects were tested for a bleeding disorder. Of the subjects who completed testing, 34 (46%) were diagnosed with a bleeding disorder. Thirty-nine subjects (54%) had heavy menstrual bleeding because of other causes. There was no significant difference in hemoglobin between those with and without a bleeding disorder. Iron deficiency anemia was significantly higher in subjects without a bleeding disorder. In a comparison of hormone therapy success, the levonorgestrel intrauterine device (89%, 8 out of 9 subjects) had the highest rate of menstrual suppression followed by norethindrone acetate 5-10 mg/d (83%, 5 out of 6 subjects), and the transdermal patch (80%, 4 out of 5 subjects). All subjects using tranexamic acid as well as hormonal therapy had 100% achievement of menstrual suppression. CONCLUSION A high frequency of bleeding disorders was found in those tested. Subjects with a bleeding disorder were less likely to present with severe anemia requiring blood transfusion and less likely to have iron deficiency anemia. Although combined oral contraceptives were commonly used clinically for menstrual suppression, they were not found to be the most effective option.

The Utility of Routine Ultrasound in the Diagnosis and Management of Adolescents with Abnormal Uterine Bleeding. J Pediatr Adolesc Gynecol 2017; 30:239-242. [PMID: 27721027 DOI: 10.1016/j.jpag.2016.09.012] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2016] [Revised: 09/26/2016] [Accepted: 09/29/2016] [Indexed: 11/24/2022]
Abstract
STUDY OBJECTIVE Despite the fact that most cases of abnormal uterine bleeding (AUB) in adolescence are due to an immature hypothalamic-pituitary-ovarian (HPO) axis, the current approach to investigating adolescents who present with AUB often includes pelvic ultrasound to exclude rare structural causes. The aim of this study was to determine whether an ultrasound ordered for the investigation of AUB in adolescents detects any significant anatomic pathology or alters diagnosis and management. DESIGN, SETTING, PARTICIPANTS, AND INTERVENTIONS A retrospective chart review of 230 patients younger than 18 years of age who presented with AUB to the gynecology clinic at the Hospital for Sick Children in Toronto, Canada between January 2010 and December 2012 was completed. MAIN OUTCOME MEASURES Findings on pelvic ultrasound and any further imaging as well as management choices for these patients were examined. RESULTS Of all patients, 67.8% (156/230) had ultrasound done as part of their AUB workup. The most common diagnosis for the patients who received ultrasound examinations and the patients who did not was AUB due to an immature HPO axis. Of the patients who received an ultrasound examination, 72.4% (113/156) had normal findings; incidental findings were identified in 17.9% (28/156) and polycystic ovary syndrome morphology in 6.4% (10/156). Structural causes of AUB were found in only 2 (1.3%) of the adolescents imaged. No patient had a change in her AUB management plan because of ultrasound findings. CONCLUSION Our results strongly suggest that pelvic ultrasound examination is not required in the initial investigation of AUB in the adolescent population because it did not alter treatment in any of our patients.

Abstract
Reproductive ecology focuses on the sensitivity of human reproduction to environmental variation. While reproductive ecology has historically focused on the relationship between energy status and reproductive outcomes, iron status is equally critical to women's reproductive health, given the wide-ranging detrimental effects of iron-deficiency anemia on maternal and infant well-being. This review interprets the vast literature on iron status and women's reproduction through an evolutionary framework. First, it will critique the evidence for iron deficiency caused by blood loss during menstruation, reinterpreting the available data as ecological variation in menses within and between populations of women. Second, it will highlight the scant but growing evidence that iron status is implicated in fertility, a relationship that has deep evolutionary roots. Third, this review proposes a new hypothesis for the transfer of iron from mother to infant via pregnancy and breastfeeding: reproductive iron withholding. In this hypothesis, mothers transfer iron to infants in a manner that helps infants avoid iron-mediated infection and oxidative stress, but trades off with potential risk of maternal and infant iron deficiency. Finally, this review explores two main factors that can modify the relationship between iron status and the gestation-lactation cycle: (1) the relationship between long-term reproductive effort (parity) and iron status and (2) supplementation schemes before and during pregnancy. The review concludes by suggesting continued research into iron homeostasis in women using evolutionary, ecological, and biocultural frameworks.

Association of iron depletion with menstruation and dietary intake indices in pubertal girls: the healthy growth study. BIOMED RESEARCH INTERNATIONAL 2013; 2013:423263. [PMID: 24455693 PMCID: PMC3885188 DOI: 10.1155/2013/423263] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/21/2013] [Accepted: 10/06/2013] [Indexed: 11/18/2022]
Abstract
The aim of the present study was to investigate the associations of iron depletion (ID) with menstrual blood losses, lifestyle, and dietary habits, in pubertal girls. The study sample comprised 1222 girls aged 9–13 years old. Biochemical, anthropometrical, dietary, clinical, and physical activity data were collected. Out of 274 adolescent girls with menses, 33.5% were found to be iron depleted (defined as serum ferritin < 12 μg/L) compared to 15.9% out of 948 girls without menses. Iron-depleted girls without menses were found to have lower consumption of poultry (P = 0.017) and higher consumption of fruits (P = 0.044) and fast food (P = 0.041) compared to their peers having normal iron status. Multivariate logistic regression analysis showed that girls with menses were 2.57 (95% CI: 1.37, 4.81) times more likely of being iron depleted compared to girls with no menses. Iron depletion was found to be associated with high calcium intake, high consumption of fast foods, and low consumption of poultry and fruits. Menses was the only factor that was found to significantly increase the likelihood of ID in these girls. More future research is probably needed in order to better understand the role of diet and menses in iron depletion.

Abstract
OBJECTIVE To examine menstrual patterns and effects of menstrual disorders on social and academic lives of undergraduate students in Kano, Nigeria. PARTICIPANTS Students attending Bayero University Kano, Nigeria (n = 383). INTERVENTION Self-administered questionnaires. MAIN OUTCOME MEASURES Sociodemographic characteristics, menstrual patterns, and associated symptoms were elicited. Treatment-seeking behavior and effects of symptoms on academic and social activities were ascertained. RESULTS The mean age at menarche was 13.7 ± 1.68 years. Menstrual bleeding lasted an average of 5.2 ± 1.6 days. Cycle length was 21-35 days in 92% of cases (n = 353). Approximately 72% of respondents reported dysmenorrhea. After adjusting for confounding, age at menarche, menstrual cycle length, duration of menstrual bleeding and use of contraceptive pills remained significant predictors of dysmenorrhea. Menstrual disorders interfered with social and academic life of 91% and 84% of respondents respectively. CONCLUSIONS Gynecologic morbidity related to menstruation is common among adolescent Nigerians and is associated with detrimental effects on academic and social activities. Student health services should prioritize measures to mitigate the social and physical impact of menstrual disorders in young women.

Abstract
OBJECTIVE To test the hypothesis that adolescent girls with menorrhagia rarely seek medical attention. STUDY DESIGN A total of 705 adolescent girls attended a lecture on menorrhagia, completed an initial anonymous questionnaire, and were asked to participate in a more comprehensive study comprising a detailed bleeding questionnaire, a pictorial blood loss assessment chart, and blood tests. RESULTS A total of 105 adolescents (15%) reported they had heavy periods on the initial questionnaire. Among the 94 girls who completed the full questionnaire, 34 reported menorrhagia (36%; 95% CI, 26.5%-46.7%). Almost one-third (11 of 34) of these girls did not perceive having menorrhagia according to their response to the initial questionnaire. Menorrhagia was not related to age, years since menarche, or family history of menorrhagia. Among the 62 girls who consented to blood testing, 6 had anemia (9.6%; 95% CI, 3.6%-19.6%), all of whom had bleeding symptoms. CONCLUSION Using standardized questionnaires, we were able to identify adolescents with menorrhagia associated with anemia. Importantly, some of these adolescents were not aware of having menorrhagia and/or anemia. Screening programs for menorrhagia in schools could result in better detection of menorrhagia among adolescents and consequent appropriate referral for medical consultation.

Abstract
AbstractObjectivesWe evaluated the association of nutrient intake with Fe deficiency with regard to lifestyle factors and health condition in young Japanese women. Uniquely among developed countries, dietary habits render Japanese populations vulnerable to Fe deficiency, owing to their relatively low intake of Fe and high intake of Fe absorption inhibitors, such as green tea and soyabeans.DesignA cross-sectional study.Setting and subjectsThe subjects were 1019 female Japanese dietetic students aged 18–25 years. Dietary habits during the preceding month were assessed using a previously validated, self-administered, diet history questionnaire. Blood analysis was performed to assess body Fe status. Subjects were categorized with Fe deficiency when their serum ferritin levels were <12 ng/ml. Twenty-nine dietary variables, i.e. intakes of energy, sixteen nutrients including Fe and twelve food groups, were analysed using multivariate logistic regression models adjusted for possible confounders.ResultsOf the subjects, 24·5 % were categorized with Fe deficiency. However, no dietary factors assessed were significantly associated with Fe deficiency. The risk of Fe deficiency was significantly lower in women with infrequent or no menstrual cycles than in those with regular cycles (OR = 0·58; 95 % CI 0·34, 1·00) and significantly higher in women with heavy menstrual flow than in women with average flow, albeit that these were self-reported (OR = 1·83; 95 % CI 1·35, 2·48).ConclusionsThese results suggest that dietary habits, including Fe intake, do not significantly correlate with Fe deficiency among young Japanese women.

Abstract
OBJECTIVE The purpose of this study was to examine the association between arsenic exposure and anemia, based on blood hemoglobin concentration. METHODS Hemoglobin measures, skin lesions, arsenic exposure, and nutritional and demographic information were collected from 1954 Bangladeshi participants in the Health Effects of Arsenic Longitudinal Study. We used general linear modeling to assess the association between arsenic exposure and hemoglobin concentration, examining men and women separately. RESULTS Arsenic exposure (urinary arsenic >200 microg/L) was negatively associated with hemoglobin among all men and among women with hemoglobin <10 d/L. Other predictors of anemia in men and women included older age, lower body mass index, and low intake of iron. Among women, the use of contraceptives predicted higher hemoglobin. CONCLUSIONS The study suggests an association between high arsenic exposure and anemia in Bangladesh.

Abstract
Haemolytic anaemia is often induced following prolonged exposure to chemical substances. Currently, under EU Council Directive 67/548/EEC, substances which induce such effects are classified as dangerous and assigned the risk phrase R48 'Danger of serious damage to health by prolonged exposure.' Whilst the general classification criteria for this endpoint are outlined in Annex VI of this Directive, they do not provide specific information to assess haemolytic anaemia. This review produced by the EU Working Group on Haemolytic Anaemia provides a toxicological assessment of haemolytic anaemia and proposes criteria that can be used in the assessment for classification of substances which induce such effects. An overview of the primary and secondary effects of haemolytic anaemia which can occur in rodent repeated dose toxicity studies is given. A detailed analysis of the toxicological significance of such effects is then performed and correlated with the general classification criteria used for this endpoint. This review intends to give guidance when carrying out an assessment for classification for this endpoint and to allow for better transparency in the decision-making process on when to classify based on the presence of haemolytic anaemia in repeated dose toxicity studies. The extended classification criteria for haemolytic anaemia outlined in this review were accepted by the EU Commission Working Group on the Classification and Labelling of Dangerous Substances in September 2004.

Abstract
OBJECTIVE The purpose of this study was to assess the usefulness of a new platelet function analyzer in the detection of von Willebrand disease and platelet dysfunction in women with menorrhagia. STUDY DESIGN Women with menorrhagia and control subjects were tested with a platelet function analyzer. If the results were abnormal, further testing was performed for possible von Willebrand disease or platelet dysfunction. Results were compared. RESULTS Of the 108 women with menorrhagia, 28 had an abnormal platelet function analysis results: 7 results were suggestive of von Willebrand disease; 17 results were suggestive of platelet dysfunction, and 4 results were inconclusive. Of the 100 control subjects, 18 subjects had an abnormal platelet function analysis result: 2 results were suggestive of von Willebrand disease; 12 results were suggestive of platelet dysfunction, and 4 results were inconclusive. The prevalence of suspected von Willebrand disease was 6% among women with menorrhagia and 2% among control subjects. Among white women, the prevalence was 10% compared with 1% among control subjects. CONCLUSION We demonstrated that the platelet function analyzer could be used to detect von Willebrand disease in women with menorrhagia.

Abstract
OBJECTIVE Anemia is a major public health concern in preschool children and pregnant women in the developing world. While many studies have examined these two at-risk groups, there is a paucity of data on anemia in adolescents living in developing countries in the complex ecologic context of poverty, parasitism, and malnutrition. We evaluated the prevalence, severity, and risk factors of anemia in adolescent schoolgirls in an area with intense malaria transmission in western Kenya. DESIGN Two cross-sectional surveys were conducted, using a multistage random sample design. SETTING Public primary schools in an area with intense malaria transmission in western Kenya. SUBJECTS A total of 648 randomly selected adolescent schoolgirls aged 12-18 y. RESULTS The prevalence of anemia (Hb <120 g/l) was 21.1%; only one girl had an Hb less than 70 g/l. Ferritin levels were available from a subsample of 206 girls. The prevalence of iron deficiency (ferritin <12 microg/l) was 19.8, and 30.4% of anemic girls were iron deficient. Malaria and schistosomiasis were the main risk factors for anemia in younger girls (12-13 y), while menstruation was the principal risk factor in older girls (14-18 y). CONCLUSIONS Iron deficiency and anemia in school-attending girls in western Kenya were more prevalent than in developed countries, but considerably less prevalent than in preschool children and pregnant women from the same study area. Our findings are consistent with other recent school-based surveys from western Kenya, but not with recent community- and school-based cross-sectional surveys from other parts of sub-Saharan Africa. It deserves further study to determine if adolescent girls not attending school are at higher risk of anemia.

Abstract
The relationship of anemia as a risk factor for maternal mortality was analyzed by using cross-sectional, longitudinal and case-control studies because randomized trials were not available for analysis. The following six methods of estimation of mortality risk were adopted: 1) the correlation of maternal mortality rates with maternal anemia prevalence derived from national statistics; 2) the proportion of maternal deaths attributable to anemia; 3) the proportion of anemic women who die; 4) population-attributable risk of maternal mortality due to anemia; 5) adolescence as a risk factor for anemia-related mortality; and 6) causes of anemia associated with maternal mortality. The average estimates for all-cause anemia attributable mortality (both direct and indirect) were 6.37, 7.26 and 3.0% for Africa, Asia and Latin America, respectively. Case fatality rates, mainly for hospital studies, varied from <1% to >50%. The relative risk of mortality associated with moderate anemia (hemoglobin 40-80 g/L) was 1.35 [95% confidence interval (CI): 0.92-2.00] and for severe anemia (<47 g/L) was 3.51 (95% CI: 2.05-6.00). Population-attributable risk estimates can be defended on the basis of the strong association between severe anemia and maternal mortality but not for mild or moderate anemia. In holoendemic malarious areas with a 5% severe anemia prevalence (hemoglobin <70 g/L), it was estimated that in primigravidae, there would be 9 severe-malaria anemia-related deaths and 41 nonmalarial anemia-related deaths (mostly nutritional) per 100,000 live births. The iron deficiency component of these is unknown.
