Does resistance training improve the functional capacity and well being of very young anorexic patients? A randomized controlled trial

PURPOSE

We determined the effects of a 3-month low-moderate-intensity strength training program (2 sessions/week) on functional capacity, muscular strength, body composition, and quality of life (QOL) in 22 young (12-16 yrs) anorexic outpatients.

METHODS

Patients were randomly assigned to a training or control group (n=11 [10 females] each). Training sessions were of low intensity (loads for large muscle groups ranging between 20%-30% and 50%-60% of six repetitions maximum [6RM] at the end of the program). We measured functional capacity by the time up and go and the timed up and down stairs tests. Muscular strength was assessed by 6RM measures for seated bench and leg presses. We estimated percent body fat and muscle mass. We assessed patients' QOL with the Short Form-36 items.

RESULTS

The intervention was well tolerated and did not have any deleterious effect on patients' health, and did not induce significant losses in their body mass. The only studied variable for which a significant interaction (group x time) effect was found (p=.009) was the 6RM seated lateral row test.

CONCLUSIONS

Low-moderate-intensity strength training does not seem to add major benefits to conventional psychotherapy and refeeding treatments in young anorexic patients.

Menstruation in adolescents: what's normal, what's not

The conventional wisdom about menstruation in adolescents, perpetuated in textbooks, requires updating. Recently published national surveys and reviews of large historical databases provide information about menstruation in adolescents, including the following: (1) Girls are experiencing earlier pubertal development than previously noted, suggesting that guidelines for the evaluation of potentially pathologic precocious puberty be reassessed. (2) There are racial differences in pubertal development, with African American girls experiencing earlier signs than Caucasian girls, and Mexican American girls intermediate in pace. (3) The absence of pubertal development by age 14 is associated with a high probability of conditions with impaired reproductive potential. (4) Absence of menarche by age 15 is statistically uncommon and should be evaluated. (5) Parameters for normal menstrual cyclicity indicate that most menstrual cycles for adolescents are between approximately 20 and 45 days. (6) Because menstrual cycles outside of this range are statistically uncommon, consideration should be give to evaluating adolescents with bleeding that is either too frequent or too infrequent. (7) A number of conditions with the potential for significant sequelae in adulthood can present as abnormal menses in adolescence, and thus merit early diagnosis and management.

High prevalence of eating disorders in narcolepsy with cataplexy: a case-control study

STUDY OBJECTIVES

To study the prevalence of and symptoms of eating disorders in patients with narcolepsy.

DESIGN

We performed a case-control study comparing symptoms of eating disorders in patients with narcolepsy versus healthy population controls, using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN 2.1). To study whether an increased body mass index (BMI) could be responsible for symptoms of an eating disorder, we also compared patients with BMI-matched controls, using the SCAN as well as the Eating Disorder Examination-Questionnaire.

SETTING

University hospital.

PATIENTS AND PARTICIPANTS

Patients with narcolepsy/cataplexy (n = 60) were recruited from specialized sleep centers. Healthy controls (n = 120) were drawn from a population study previously performed in the Netherlands. Separately, 32 BMI-matched controls were recruited.

INTERVENTIONS

N/A.

MEASUREMENTS AND RESULTS

In total, 23.3% of the patients fulfilled the criteria for a clinical eating disorder, as opposed to none of the control subjects. Most of these were classified as Eating Disorder-Not Otherwise Specified, with an incomplete form of binge eating disorder. On the symptom level, half of the patients reported a persistent craving for food, as well as binge eating. Twenty-five percent of patients even reported binging twice a week or more often. When compared with BMI-matched controls, the significant increases persisted in symptoms of eating disorders among patients with narcolepsy. Except for a higher level of interference in daily activities due to eating problems in patients using antidepressants, medication use did not influence our findings.

CONCLUSIONS

The majority of patients with narcolepsy experience a number of symptoms of eating disorders, with an irresistible craving for food and binge eating as the most prominent features. Eating disorder symptomatology interfered with daily activities. These findings justify more attention for eating disorders in the treatment of patients with narcolepsy.

Severe eating disorder initially diagnosed in a 72-year-old man

OBJECTIVE

Eating disorders in our society mainly affect young women. Cases in males are far less common, and reported cases in elderly males are rare.

METHOD

We report the case of 72-year- old male admitted to a geriatric psychiatry service for grave passive neglect with mild dementia thought to be due to nutritional deficiency.

RESULTS

The patient was found to have an eating disorder not otherwise specified, most closely resembling anorexia nervosa, which was believed to be the cause of the nutritional problem.

CONCLUSION

This case highlights the need for diagnostic awareness regarding eating disorders in patients of all ages and of both genders.

Correlates of the stages of change for physical activity in a population survey

OBJECTIVES

We sought to identify variables associated with being in a particular stage of change for physical activity-a measure of behavioral intention to engage in regular physical activity. Understanding behavioral intentions can be useful in explaining why individuals are physically inactive or active.

METHODS

Data from the Rhode Island 2000 Behavioral Risk Factor Surveillance System were used to evaluate predictors of stage of change for physical activity. There were 3454 observations in the data set, representing a weighted population of 742636 people. Estimates were obtained from polytomous multiple logistic models.

RESULTS

Being a woman, Hispanic, non-Hispanic Black, and older than 55 years of age were associated with being in precontemplation and contemplation stages of change rather than maintenance. Self-perceived health status and rarely feeling healthy or full of energy were strongly predictive of stage of change. Having a health limitation was a dichotomous predictor, predicting being in action and precontemplation stages.

CONCLUSIONS

Several sociodemographic and health variables were associated with varying patterns of stages of change for physical activity. The complexity of individual intentions for physical activity provides evidence for the potential existence of mediating, effect-modifying, and confounding variables that differ depending on individual characteristics.

Disorders of Fuel Metabolism: Medical Complications Associated with Starvation, Eating Disorders, Dietary Fads, and Supplements

Disorders of fuel metabolism as they relate to abnormal fuel intake,abnormal fuel expenditure, and dietary supplements are the focus of this article. The emergency physician should be aware of the medical complications that can occur as a result of starvation states,eating disorders, fad diets, hypermetabolic states, and ergogenic aids. Knowledge and understanding of the complications associated with these disorders will facilitate the diagnosis and management of patients who present to the emergency department with any of the disorders reviewed.

The Cardiovascular Effects of Chronic Hypoestrogenism in Amenorrhoeic Athletes

In premenopausal women, the most severe menstrual dysfunction is amenorrhoea, which is associated with chronic hypoestrogenism. In postmenopausal women, hypoestrogenism is associated with a number of clinical sequelae related to cardiovascular health. A cardioprotective effect of endogenous oestrogen is widely supported, yet recent studies demonstrate a deleterious effect of hormone replacement therapy for cardiovascular health. What remain less clear are the implications of persistently low oestrogen levels in much younger amenorrhoeic athletes. The incidence of amenorrhoea among athletes is much greater than that observed among sedentary women. Recent data in amenorrhoeic athletes demonstrate impaired endothelial function, elevated low- and high-density lipoprotein levels, reduced circulating nitrates and nitrites, and increased susceptibility to lipid peroxidation. Predictive serum markers of cardiovascular health, such as homocysteine and C-reactive protein, have not yet been assessed in amenorrhoeic athletes, but are reportedly elevated in postmenopausal women. The independent and combined effects of chronic hypoestrogenism and exercise, together with subclinical dietary behaviours typically observed in amenorrhoeic athletes, warrants closer examination. Although no longitudinal studies exist, the altered vascular health outcomes reported in amenorrhoeic athletes are suggestive of increased risk for premature cardiovascular disease. Future research should focus on the presentation and progression of these adverse cardiovascular parameters in physically active women and athletes with hypoestrogenism to determine their effects on long-term health.
