Patterns of menstrual disturbance in eating disorders

OBJECTIVE: To describe menstrual disturbance in eating disorders (ED). METHOD: We describe menstrual history in 1,705 women and compare eating, weight, and psychopathological traits across menstrual groups. RESULTS: Menstrual dysfunction occurred across all eating disorder subtypes. Individuals with normal menstrual history and primary amenorrhea reported the highest and lowest lifetime body mass index (BMI), respectively. Normal menstruation and oligomenorrhea groups reported greater binge eating, vomiting, and appetite suppressant use. Amenorrhea was associated with lower caloric intake and higher exercise. Harm avoidance, novelty seeking, perfectionism, and obsessionality discriminated among menstrual status groups. No differences in comorbid Axis I and II disorders were observed. CONCLUSION: Menstrual dysfunction is not limited to any eating disorder subtype. BMI, caloric intake, and exercise were strongly associated with menstrual function. Menstrual status is not associated with comorbidity. Menstrual irregularity is an associated feature of all ED rather than being restricted to AN only.     

The association of behavior and lifestyle factors with menstrual symptoms

The present study examines the association of obesity, cigarette smoking, alcohol consumption, and exercise with the prevalence of menstrual cycle disorders among 2912 women aboard U.S. Navy ships. Self-administered surveys obtained information on weight, height, cigarette smoking, alcohol consumption, and exercise. Participants also indicated whether they experienced cramps or pain during their period requiring medication or time off work, bleeding between periods, excessive frequency of periods, heavy periods, periods lasting for longer than a week, scanty menstrual flow, and irregular periods during the past 90 days. Women ranged in age from 18 to 49 years, with an average of 26 years. After adjustment for age, race, and pay grade, current cigarette smoking was associated with increased risk of all menstrual symptoms and cycle disorders. As compared with nonsmokers, current smokers were at increased risk of cramps or pain requiring medication or time off work (odds ratio [OR] = 1.13, 95% confidence interval [CI] = 1.03, 1.25), bleeding between periods (OR = 1.22, CI = 1.09, 1.38), excessive frequency of periods (OR = 1.33, CI = 1.17, 1.51), heavy periods (OR = 1.17, CI = 1.06, 1.29), periods lasting longer than a week (OR = 1.31, CI = 1.16, 1.48), scanty flow (OR = 1.13, CI = 1.01, 1.29), and irregular periods (OR = 1.14, CI = 1.05, 1.24). Obesity, exercise, and alcohol consumption did not show consistent associations with menstrual symptoms or cycle disorders. Logistic regression models that included age, race, pay grade, and all behavioral and lifestyle variables indicated only cigarette smoking was associated with an increased risk of bleeding between periods (OR = 1.33, CI = 1.05, 1.68), excessive frequency of periods (OR = 1.38, CI = 1.21, 1.58), periods lasting longer than a week (OR = 1.45, CI = 1.13, 1.84), and irregular periods (OR = 1.25, CI = 1.05, 1.47). Although the lifestyle factors are all potentially modifiable, results suggest that only interventions targeted at smoking cessation might be useful in reducing the prevalence of menstrual symptoms, cycle disorders, and time lost from work.     

Neuroendocrine Regulation of the Menstrual Cycle

Normal reproductive function in the human female is the result of complex Interactions among brain, pituitary, and ovary. Recognition of the key role of the CNS in this integrated system has provided a logical basis for the well-known relationship between psychoneuroendocrine disorders and menstrual dysfunction, and led to major improvements in the diagnosis and treatment of some menstrual disorders.     

Cognitive dietary restraint is associated with eating behaviors,lifestyle practices,personality characteristics and menstrual irregularity in college women

This study characterized associations of restraint with selected physical, lifestyle, personality and menstrual cycle characteristics in female university students. The survey instrument, distributed to 1350 women, included standardized questionnaires (Three-Factor Eating Questionnaire, Perceived Stress Scale and Rosenberg's Self-esteem Scale), and assessed weight and dieting history, exercise, lifestyle characteristics, menstrual cycle characteristics and whether participants were following vegetarian diets. Among the 596 respondents included in the analysis (44%), women with high (n=145), medium (n=262) or low (n=189) restraint had similar ages, heights and weights. Despite this, compared to women with low scores, those with high scores exercised more (4.6+/-5.3 vs. 3.2+/-3.5 h/wk), were more likely to be vegetarian (14.5 vs. 3.7%), have a history of eating disorders (13.7 vs. 1.2%), be currently trying to lose weight (80.3 vs. 15.3%), report irregular menstrual cycles (34.7 vs. 17.0%), and have scores reflecting lower self-esteem and higher perceived stress. Menstrual irregularity was an independent predictor of restraint score, and restraint score was the only variable to differentiate women with regular and irregular menstrual cycles. We conclude that women with high restraint may use a combination of behavioral strategies for weight control, and differ from women with low restraint scores in personality characteristics and weight history. Some of these behaviors or characteristics may influence menstrual function.     

Abnormal eating attitude test scores predict menstrual dysfunction in lean females

The role of subnormal nutrition and subclinical anorexia nervosa as factors associated with menstrual dysfunction in lean females has not been defined. We studied the relationship between elevated scores for the Eating Attitudes Test (EAT) and the Eating Disorders Inventory (EDI) and menstrual dysfunction in 88 predominantly lean female marathon runners, ballet dancers, and fashion models. For analysis, the subjects were categorized according to their weight classification and exercise status into low-mass nonexercisers, low-mass exercisers, and moderate-mass exercisers. Menstrual dysfunction was equally common in all groups (43–55%); the incidence of elevated EAT and EDI scores was high in all groups (15–65%). Elevated EAT test scores, but not body mass or exercise, were associated with menstrual dysfunction (p = 0.009). Subnormal nutrition may be the critical yet unrecognized factor explaining menstrual dysfunction in lean women.     

Menstrual disorders and occupational, stress, and racial factors among military personnel

Few studies have assessed multiple stress factors as a potential risk for menstrual disorders. This study evaluated whether work-related stress or life event stress was associated with alterations in menstrual function of military personnel. The study is unique in that it evaluated the association between race and three job factors--job stress, handling chemical mixtures, and being a military or civilian employee of the US Air Force. A comprehensive questionnaire was administered to 170 healthy, premenopausal employed women to examine the relationship between work-related or life event stress and menstrual disorders. Multiple logistic regression analyses showed no statistically significant association between work-related stress and menstrual disorders, whereas life event stress was significantly associated with dysmenorrhea (odds ratio [OR], 2.20; 95% confidence interval [CI], 1.08 to 4.50) abnormal cycle length (OR, 3.42; CI, 1.12 to 10.50), and hypermenorrhea (OR, 2.99; 95% CI, 1.20 to 7.42). Having one or more menstrual disorders was significantly associated with life events by race interaction (OR, 6.52; 95% CI, 2.45 to 17.36). Non-Caucasians had significantly increased risks of hypermenorrhea (OR, 4.99; 95% CI, 2.07 to 12.05) and abnormal cycle length (OR, 4.12; 95% CI, 1.47 to 11.55). The prevalence of menstrual disorders in this military population was 31.2% for dysmenorrhea, 17.9% for hypermenorrhea, and 12.0% for abnormal cycle length. This study suggests that women in the military report less day-to-day job stress but more atypical life events, including those related to their jobs, and that these life events are associated with adverse menstrual consequences.     

民航女乘务员生殖功能的流行病学调查

为了解飞机乘务员职业对女性生殖功能的影响，应用横断面及回顾性群组研究方法对某航空公司５３６名女乘务员及对照组４１７人的月经及生殖结局进行了调查。结果表明，乘务员组月经异常患病率明显高于对照组，主要表现为月经周期异常及痛经患病率增高。乘务员组的不良生殖结局（自然流产、死胎死产、早产、出生缺陷等）与对照组比未见显著性差异     

The clinical rationale for menses-free contraception

The impact of monthly menstruation may range from a minor inconvenience for some women to a major health concern for those who suffer from menstrual disorders and health conditions that are aggravated during their menstrual cycle. Oral contraceptives (OCs) have been used safely in continuous regimens for the treatment of menstrual disorders in some women and for others who choose to extend their 28-day menstrual cycle to accommodate major life events. There is no physiological requirement for the monthly hormone withdrawal bleed that is experienced by women taking cyclic OCs or for a menstrual period in women who do not desire to (or cannot) become pregnant. Thus, the use of continuous or extended-cycle OC regimens that eliminate the menstrual cycle represents a viable and attractive option for many women. The availability of more choices for menstrual suppression, such as continuous use of OCs, will improve the quality of life for many women who suffer from menstrual-related disorders and provide greater convenience for women with busy and active lifestyles.     

Eating and weight disorders in the female athlete.

This paper presents an overview of eating disorders, including definitions, clinical criteria for appropriate diagnosis, and a discussion of the potential for increased risk for eating disorders in special populations of female athletes. This is followed by a discussion of the prevalence of eating disorders in normal and athletic populations. From this discussion, it seems clear that female athletes in endurance or appearance sports are at an increased risk for disordered eating. Finally, the paper focuses on related disorders--a triad associating eating disorders, menstrual dysfunction, and bone mineral disorders. It is clear that secondary amenorrhea is associated with malnutrition and disordered eating. Further, bone mineral disorders are related to menstrual dysfunction. Disordered eating may represent the initiating factor of this triad.     

Disorders of ovulation

A regular ovulatory menstrual cycle requires a functional and integrated feedback system involving the hypothalamus, the anterior pituitary and the ovary (Figure 1). In the normal menstrual cycle, periods occur at regular intervals of 21-35 days and bleeding lasts for up to 7 days. Disorders of ovulation usually cause menstrual disturbance and present with irregular periods (oligomenorrhoea) or absent periods (amenorrhoea). Irregular periods with anovulatory cycles are commonest under age 20 and over age 40. Ovulatory disorders account for one-quarter of couples presenting with infertility. Anovulation may be classified by the anatomical location of the defect in the hypothalamo-pituitary-ovarian axis (Figure 2). By focusing on ovarian, hypothalamic and endocrine defects, this article offers an overview of the disorders of ovulation.     

Menstrual cycle abnormalities: diagnosis and management.

In summary, the diagnosis and management of menstrual disorders in adolescent girls is a particular challenge. The clinician must keep an open mind and consider physical conditions as well as psychosocial factors that may play a role in the menstrual dysfunction. Knowledge of congenital and genetic conditions, chronic biomedical as well as psychosomatic disorders, lifestyle choices, and complications of sexual behavior are essential to properly diagnose and treat menstrual disorders in young women. A detailed and confidential medical and psychosocial history and a thorough physical examination, including external genital examination, rectoabdominal or vaginal bimanual examination, and speculum examination (if indicated) are necessary.     

Self-Reported Restrictive Eating,Eating Disorders,Menstrual Dysfunction,and Injuries in Athletes Competing at Different Levels and Sports

The purpose of this study was to investigate the prevalence of self-reported restrictive eating, current or past eating disorder, and menstrual dysfunction and their relationships with injuries. Furthermore, we aimed to compare these prevalences and associations between younger (aged 15–24) and older (aged 25–45) athletes, between elite and non-elite athletes, and between athletes competing in lean and non-lean sports. Data were collected using a web-based questionnaire. Participants were 846 female athletes representing 67 different sports. Results showed that 25%, 18%, and 32% of the athletes reported restrictive eating, eating disorders, and menstrual dysfunction, respectively. Higher rates of lean sport athletes compared with non-lean sport athletes reported these symptoms, while no differences were found between elite and non-elite athletes. Younger athletes reported higher rates of menstrual dysfunction and lower lifetime prevalence of eating disorders. Both restrictive eating (OR 1.41, 95% CI 1.02–1.94) and eating disorders (OR 1.89, 95% CI 1.31–2.73) were associated with injuries, while menstrual dysfunction was associated with more missed participation days compared with a regular menstrual cycle (OR 1.79, 95% CI 1.05–3.07). Our findings indicate that eating disorder symptoms and menstrual dysfunction are common problems in athletes that should be managed properly as they are linked to injuries and missed training/competition days.     

Menstruation disorders more frequent in women with a history of sexual abuse

OBJECTIVE: To determine the relationship between menstruation disorders and prior sexual abuse. DESIGN: Questionnaire investigation. METHOD: A questionnaire was developed consisting of 50 questions about menstruation disorders, premenstrual syndrome and sexual abuse. The questionnaire was mailed to all female patients aged 12-54 years (n = 1805) of one family practice in Den Helder, the Netherlands. RESULTS: The response rate to the questionnaire was 69% (n = 1254). After excluding women who were postmenopausal, pregnant, without a uterus, or who did not answer the questions on sexual abuse, 947 remained. Of these women, 83 (8.7%) reported having experienced sexual abuse. These women had significantly more dysmenorrhoea, more dysfunctional menstrual bleeding and significantly more menstrual cycle irregularities. CONCLUSION: A statistically significant association was found between menstrual problems and prior sexual abuse. Sexual abuse should be considered in the differential diagnosis and treatment of women who seek medical help for inexplicable menstrual disorders.     

The prevalence of disordered eating, menstrual dysfunction, and low bone mineral density among US collegiate athletes

The purpose of this study was to examine the prevalence of disordered eating (DE), menstrual dysfunction (MD), and low bone mineral density (BMD) among US collegiate athletes (n = 112) representing 7 different sports (diving, swimming, x-country, track, tennis, field hockey, and softball) and determine differences in prevalence existed between athletes participating in lean-build (LB) and non-lean build (NLB) sports. DE and MD were assessed by a health, weight, dieting, and menstrual history questionnaire. Spinal BMD was determined via dual energy x-ray absorptiometry. Twenty-eight athletes met the criteria for DE, twenty-nine for MD, and two athletes had low BMDs (using a Z score below -2.0). Ten athletes met the criteria for two disorders (one with disordered eating and low BMD and nine with disordered eating and menstrual dysfunction), while only one athlete met the criteria for all three disorders. Using a Z score below -1.0, two additional athletes met the criteria for all three disorders and three more athletes met the criteria for a combination of two disorders. With the exception of MD, which was significantly more prevalent among LB vs. NLB sports (P = 0.053), there were no differences between the groups in the prevalence of individual disorders or combinations of disorders. These data indicate that the combined prevalence of DE, MD, and low BMD among collegiate athletes is small; however, a significant number suffer from individual disorders of the Triad.     

Menstruation: choosing whether...and when

For many women in the United States, menstruation is a major health concern because menstrual disorders and other conditions that may be aggravated during menses (e.g., migraine headaches, epilepsy) carry substantial morbidity. Women today menstruate nearly 3 times as often as in primitive societies, and evidence suggests that frequent, repetitive menstrual cycles may increase health risks. Because the conventional 21/7 combination oral contraceptive (OC) regimen provides only limited relief for women with menstrual disorders, alternative OC regimens that reduce menstrual frequency have been proposed. A new OC formulation specifically designed to decrease menstrual bleeding to 4 times per year is currently under investigation. Most women welcome less frequent menses or even amenorrhea. Women who may derive particular benefit from reduced menstrual frequency include not only those with medical conditions directly caused or aggravated by menses, but also those serving in the military, female athletes, mentally-retarded women with menstrual hygiene problems, young teens, and perimenopausal women.     

Assessment of disorders of ovulation

Assessment of ovulation starts with a detailed menstrual history as menstruation provides the outward sign of the rhythmic changes taking place in the hypothalamus, the pituitary, the ovaries and the endometrium. Regular menstrual cycles in the range 25-35 days are usually indicative of ovulation. Patients with disorders of ovulation often experience absent periods (amenorrhoea) or irregular periods (oligomenorrhoea). Patients experiencing these symptoms require a detailed medical assessment based on a full history and examination followed by appropriate endocrine and imaging investigations. Through its focus on history and examination, laboratory and diagnostic assessment, detection of ovulation and detection of ovarian reserve, this article reviews the effective assessment of disorders of ovulation     

The Etiology of Some Menstrual Disorders: A Gynecological and Psychiatric Issue

Some menstrual disorders with distinct gynecological character such as amenorrhea or menometrorrhagia (MMR) may have psychogenic etiology. On the other hand, in menstrual psychosis (MP), a distinctly psychiatric disorder, the etiology is not necessarily psychogenic, but rather is hormonal–biological. We present 4 cases, one each of primary and secondary amenorrhea, MMR, and MP, respectively. In the first 3 cases (2 amenorrhea and 1 MMR), we found psychogenic factors: an insult to feminine development after rape (case 1) or marriage problems (cases 2 and 3). In the case of a recurrent MP, no relevant psychological etiology was found. Furthermore, some of the patient's relatives had menstrual or peripartum psychiatric disorders. Menstrual disorders’ etiology can be psychogenic or hormonal. The correct etiology is the guide for the adequate therapeutic way: psychotherapy based in psychogenic disorders and neuroleptic or antiovulatory drugs in those of biological etiology.     

Relationships Between Menstrual and Menopausal Attitudes and Associated Demographic and Health Characteristics: The Hilo Women's Health Study

The objective of this study was to examine the relation of menstrual attitudes to menopausal attitudes and the demographic and health characteristics associated with each. This cross-sectional study consisted of a randomly selected sample of 1,824 respondents aged 16 to 100 years in multi-ethnic Hilo, Hawai'i. Women completed questionnaires for demographic and health information, such as age, ethnicity, education, residency in Hawai'i, menopausal status, exercise, and attitudes toward menstruation and menopause. Women more often chose positive terms, such as “natural,” to describe menstruation (60.8%) and menopause (59.4%). In bivariate analyses, post-menopausal women were significantly more likely to have positive menstrual and menopausal attitudes than pre-menopausal women. Factor analyses were used to cluster attitudes followed by linear regression to identify demographic characteristics associated with factor scores. Asian-American ethnicity, higher education, reporting more exercise, and growing up outside of Hawai'i were associated with positive menstrual attitudes. Higher education, older age, post-menopausal status, growing up outside of Hawai'i and having hot flashes were associated with positive menopausal attitudes. Bivariate correlation analyses suggested significant associations between factor scores for menstrual and menopausal attitudes. Both negative and positive menstrual attitudes were positively correlated with the anticipation of menopause, although negative attitudes toward menstruation were negatively correlated with menopause as a positive, natural life event. Demographic variables, specifically education and where one grows up, influenced women's attitudes toward menstruation and menopause and should be considered for inclusion in subsequent multi-ethnic studies. Further research is also warranted in assessing the relationship between menstrual and menopausal attitudes.     

The relation of physical activity and exercise to mental health

Mental disorders are of major public health significance. It has been claimed that vigorous physical activity has positive effects on mental health in both clinical and nonclinical populations. This paper reviews the evidence for this claim and provides recommendations for future studies. The strongest evidence suggests that physical activity and exercise probably alleviate some symptoms associated with mild to moderate depression. The evidence also suggests that physical activity and exercise might provide a beneficial adjunct for alcoholism and substance abuse programs; improve self-image, social skills, and cognitive functioning; reduce the symptoms of anxiety; and alter aspects of coronary-prone (Type A) behavior and physiological response to stressors. The effects of physical activity and exercise on mental disorders, such as schizophrenia, and other aspects of mental health are not known. Negative psychological effects from exercise have also been reported. Recommendations for further research on the effects of physical activity and exercise on mental health are made.     

Relationship between Delivery Type and Menstrual Disorders: A Case-Control Study

Background: High incidence of menstrual disorders at late ages of fertility ac-counts for 20% of clinical visits and 25% of gynecological surgeries. This study was conducted to identify the relationship between delivery type and menstrual disorders in women referring to hospitals affiliated to Medical Universities in Tehran in 2008. Methods: In this case-control study, which was conducted from April to August, 2008 in Tehran, 160 women aged 36 to 44 years, 8o women with and 80 without menstrual disorder as case and control groups were enrolled respectively. Data collection tool was a questionnaire (included questions regarding demographic and obstetrical characteristics). Higham pictorial chart (scores more than 80 denoted menorrhagia), a verbal multidimensional scoring scale (from 0 for painless to 3 for severe pain), and Holmes-Rahe scale for assessing stress were used. Results: About 93.1% of the cases and 65% of the controls had experienced dysmenorrhea at the begging of the study (P=0.009). In other words, 65% of women with dysmenorrhea had a history of C-section. Women with menstrual disorders had more caesarian sections (53.7%) than those without the disorders (27.5%) (P<0.001) with an odds ratio estimate of 3.06 [95% CI: 1.58, 5.91]. There were significant differences in the number of pads/tampons used (P=0.009) and amount of uterine bleeding based on Higham chart (P=0.009) among case and control group. Conclusion: Caesarian may be considered as a risk factor for menstrual disor-ders particularly at late ages of fertility. Therefore, pregnant women should be consulted by health providers regarding advantages versus disadvantages of caesarian before selective C-section.
