RESUMO

BACKGROUND: Epidemiological data offer conflicting views of the natural course of binge-eating disorder (BED), with large retrospective studies suggesting a protracted course and small prospective studies suggesting a briefer duration. We thus examined changes in BED diagnostic status in a prospective, community-based study that was larger and more representative with respect to sex, age of onset, and body mass index (BMI) than prior multi-year prospective studies. METHODS: Probands and relatives with current DSM-IV BED (n = 156) from a family study of BED ('baseline') were selected for follow-up at 2.5 and 5 years. Probands were required to have BMI > 25 (women) or >27 (men). Diagnostic interviews and questionnaires were administered at all timepoints. RESULTS: Of participants with follow-up data (n = 137), 78.1% were female, and 11.7% and 88.3% reported identifying as Black and White, respectively. At baseline, their mean age was 47.2 years, and mean BMI was 36.1. At 2.5 (and 5) years, 61.3% (45.7%), 23.4% (32.6%), and 15.3% (21.7%) of assessed participants exhibited full, sub-threshold, and no BED, respectively. No participants displayed anorexia or bulimia nervosa at follow-up timepoints. Median time to remission (i.e. no BED) exceeded 60 months, and median time to relapse (i.e. sub-threshold or full BED) after remission was 30 months. Two classes of machine learning methods did not consistently outperform random guessing at predicting time to remission from baseline demographic and clinical variables. CONCLUSIONS: Among community-based adults with higher BMI, BED improves with time, but full remission often takes many years, and relapse is common.

RESUMO

BACKGROUND AND OBJECTIVES: Anabolic-androgenic steroid (AAS) use has become a major worldwide substance use disorder, affecting tens of millions of individuals. Importantly, it is now increasingly recognized that some individuals develop uncharacteristically violent or criminal behaviors when using AAS. We sought to summarize available information on this topic. METHODS: We reviewed the published literature on AAS-induced behavioral effects and augmented this information with extensive observations from our clinical and forensic experience. RESULTS: It is now generally accepted that some AAS users develop uncharacteristically violent or criminal behaviors while taking these drugs. Although these behaviors may partially reflect premorbid psychopathology, sociocultural factors, or expectational effects, accumulating evidence suggests that they are also attributable to biological effects of AAS themselves. The mechanism of these effects remains speculative, but preliminary data suggest a possible role for brain regions involved in emotional reactivity, such as the amygdala and regions involved in cognitive control, including the frontal cortex. For unknown reasons, these effects appear idiosyncratic; most AAS users display few behavioral effects, but a minority develops severe effects. CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Professionals encountering AAS users in clinical or forensic settings should be alert to the possibility of AAS-induced violence or criminality and should employ strategies to assess whether AAS is indeed a contributory factor in a given case. Further research is needed to elucidate the mechanism of AAS-induced violence and to explain why only a subset of AAS users appears vulnerable to these effects. (Am J Addict 2021;00:00-00).

RESUMO

OBJECTIVE: Recent reports from our laboratory and others suggest that the menopausal transition may represent a window of vulnerability for eating disorders in women. Here, we present new findings regarding this issue. METHODS: We surveyed 230 women aged 40-60 years using an anonymous questionnaire focused on eating-disorder and body-image symptomatology. We then compared groups of respondents based on (a) menopausal stage as assessed by World Health Organization (WHO) criteria and (b) menopausal symptomatology as assessed by the Menopause Rating Scale (MRS). RESULTS: WHO-defined menopausal stage (premenopausal, perimenopausal, and postmenopausal) showed no significant associations with eating and body-image measures. However, MRS scores showed strong associations with most measures of the Eating Disorder Examination Questionnaire, as well as with questions regarding satisfaction with body image. These associations remained little changed even when removing the four psychological items from the MRS score and examining only the association of the MRS somato-vegetative and urogenital items with these outcome variables. DISCUSSION: Our data augment existing evidence that the menopausal transition may be associated with eating and body-image disturbances. However, reported menopausal stage, which is difficult to define reliably, may be less informative than menopausal symptoms as a predictor of disordered eating and associated symptoms. LEVEL OF EVIDENCE: V-descriptive survey study.

RESUMO

A number of studies have examined the association of the three major eating disorders - anorexia nervosa, bulimia nervosa, and binge-eating disorder - with metabolic syndrome, or with individual components of metabolic syndrome, such as obesity, type 2 diabetes, hypertension, and dyslipidemia. Present evidence suggests that anorexia nervosa confers no excess risk of metabolic syndrome and may be associated with lower risk of certain metabolic syndrome components, including obesity and type 2 diabetes. Bulimia nervosa shows associations with increased risk for metabolic syndrome components in some studies, but not in others. Binge-eating disorder, however, is strongly associated with increased risk for both metabolic syndrome and its components - and these associations appear to be mediated not only through elevated body weight, but also possible body-weight-independent factors. Given that binge-eating disorder is the most common eating disorder, treatment and prevention of metabolic syndrome in this group represents a significant clinical and public health challenge.

RESUMO

OBJECTIVE: The literature on eating disorders in older males is still very limited. We assessed the relationship between aging male symptomatology and eating behavior in middle-aged and older men. METHOD: We distributed anonymous questionnaires to men aged 40-75 years living in or near Innsbruck, Austria, covering demographic items, current eating disorder symptoms (as defined by DSM-5), and associated measures of eating pathology, body image, and sports activity (including exercise addiction). We also administered the Aging Males' Symptoms scale (AMS), and classified respondents as "high-AMS" (AMS score ≥37; N = 82) or "low-AMS" (AMS score <37; N = 386). RESULTS: High-AMS men reported a significantly higher mean current BMI, a greater prevalence of eating disorder symptoms, higher scores on the Eating Disorder Examination Questionnaire, greater risk of exercise addiction, and more negative body image than low-AMS men. DISCUSSION: We found a marked association between aging-male symptomatology and eating-disorder symptomatology in aging men. Our findings suggest that clinicians should carefully inquire about eating disorder symptoms in men aged 40 and above reporting aging-male symptomatology. Importantly, several men in the study reported "purging" via excessive exercise (as opposed to the more common methods of vomiting or use of laxatives or diuretics), and therefore this should be a subject of inquiry in clinical evaluations. To pursue these findings, subsequent studies of eating disorders in older men should consider assessing endocrinological measures, particularly testosterone levels, and should use longitudinal designs.

RESUMO

BACKGROUND AND OBJECTIVES: The majority of anabolic androgenic steroid (AAS) studies have focused on the general male population. Approximately 15% of gay or bisexual men are seropositive for HIV and many AASs are administered via injection. Thus, AAS use among gay and bisexual men likely poses a greater risk of spreading infectious disease. Gay and bisexual men who use AAS were compared with non-users regarding self-reported seropositivity for HIV and hepatitis B and C, sexual behaviors and injection practices, illicit drug and alcohol use, and psychiatric disorders. METHODS: The CASTRO (Castro Anabolic Steroid Research Observation) study was a 108-item cross-sectional survey of 153 gay and bisexual men who exercise. Data collection occurred outside four gyms in the San Francisco Castro District. RESULTS: The lifetime prevalence of AAS use among gay and bisexual men in the study was 21.6%. AAS users and non-users did not differ in self-reported seropositivity for HIV or hepatitis B and C, but AAS users reported higher rates of male-male condomless anal sex in the past year (84.8 vs 60.8%, p < .01) than non-users. More AAS users used ecstasy and methamphetamines (39.4 vs 16.7%, p < .01 and 18.2 vs 5.0%, p = .01, respectively) than non-users. DISCUSSION AND CONCLUSIONS: Gay and bisexual men who used AAS were more likely to engage in unsafe sexual behaviors and use illicit drugs relative to non-users. Multiple factors place AAS users at higher risks for spreading infectious diseases. SCIENTIFIC SIGNIFICANT: Our study suggests increased infectious disease risk among gay and bisexual men who use AAS. (Am J Addict 2019;XX:1-10).

RESUMO

BACKGROUND: Millions of individuals have used illicit anabolic-androgenic steroids (AAS), but the long-term cardiovascular associations of these drugs remain incompletely understood. METHODS: Using a cross-sectional cohort design, we recruited 140 experienced male weightlifters 34 to 54 years of age, comprising 86 men reporting ≥2 years of cumulative lifetime AAS use and 54 nonusing men. Using transthoracic echocardiography and coronary computed tomography angiography, we assessed 3 primary outcome measures: left ventricular (LV) systolic function (left ventricular ejection fraction), LV diastolic function (early relaxation velocity), and coronary atherosclerosis (coronary artery plaque volume). RESULTS: Compared with nonusers, AAS users demonstrated relatively reduced LV systolic function (mean±SD left ventricular ejection fraction = 52±11% versus 63±8%; P<0.001) and diastolic function (early relaxation velocity = 9.3±2.4 cm/second versus 11.1±2.0 cm/second; P<0.001). Users currently taking AAS at the time of evaluation (N=58) showed significantly reduced LV systolic (left ventricular ejection fraction = 49±10% versus 58±10%; P<0.001) and diastolic function (early relaxation velocity = 8.9±2.4 cm/second versus 10.1±2.4 cm/second; P=0.035) compared with users currently off-drug (N=28). In addition, AAS users demonstrated higher coronary artery plaque volume than nonusers (median [interquartile range] 3 [0, 174] mL3 versus 0 [0, 69] mL3; P=0.012). Lifetime AAS dose was strongly associated with coronary atherosclerotic burden (increase [95% confidence interval] in rank of plaque volume for each 10-year increase in cumulative duration of AAS use: 0.60 SD units [0.16-1.03 SD units]; P=0.008). CONCLUSIONS: Long-term AAS use appears to be associated with myocardial dysfunction and accelerated coronary atherosclerosis. These forms of AAS-associated adverse cardiovascular phenotypes may represent a previously underrecognized public-health problem.

RESUMO

BACKGROUND: Anabolic-androgenic steroid (AAS) use is known to be associated with other psychiatric disorders, such as body image disorders, conduct disorder/sociopathy, and other substance use disorders (SUD) - but the causal pathways among these conditions remain poorly delineated. METHODS: We created a directed acyclic graph to diagram hypothesized relationships among AAS use and dependence, body image disorder (BID), conduct disorder/sociopathy, and other SUD. Using proportional hazards models, we then assessed potentially causal relationships among these variables, using a dataset of 233 male weightlifters, of whom 102 had used AAS. RESULTS: BID and conduct disorder/sociopathy both strongly contributed to the development of AAS use, but did not appear to contribute further to the progression from AAS use to AAS dependence. Other SUD beginning prior to first AAS use - whether broadly defined or restricted only to opioids - failed to show an effect on AAS use or progression to AAS dependence. Conversely, AAS use contributed significantly to the subsequent first-time development of opioid use disorders but did not significantly increase the risk for first-time development of non-opioid SUD, taken as a whole. CONCLUSIONS: Our analysis suggests that AAS use and other SUD are mutually attributable to underlying conduct disorder/sociopathy. SUD do not appear to represent a 'gateway' to subsequent AAS use. AAS use may represent a gateway to subsequent opioid use disorder, but probably not to other SUD.

RESUMO

Recent years have seen renewed interest and research about the use of hallucinogens as possible agents in the treatment of psychiatric disorders. However, we are unaware of studies assessing the current attitudes of American psychiatrists regarding hallucinogens. Therefore, we e-mailed surveys to 1000 members of the American Psychiatric Association-250 resident-fellows and 750 attending psychiatrists. The response rate was 32.4%. Respondents tended to perceive hallucinogens as potentially hazardous and appropriately illegal for recreational purposes. However, a large minority expressed optimism about the potential use of hallucinogens for psychiatric treatment. Male and trainee respondents, as compared with female and attending respondents, reported less concern about the risks of hallucinogens and greater optimism about their therapeutic potential. Younger psychiatrists also seemed more optimistic. Optimism among trainees and younger psychiatrists may possibly reflect greater exposure to recent positive publications about hallucinogens and less awareness of more negative past reports.

RESUMO

BACKGROUND: Limited studies based in England and Australia reported misuse of anabolic-androgenic steroids (AAS) among homosexual men to enhance body image. Anecdotally, AAS are also being misused by homosexual men in the United States. Since many AAS and certain performance enhancing drugs (PEDs) are administered via injection, this poses a potential vector for the spread of infectious disease in an already at-risk population. OBJECTIVES: This study compared and contrasted homosexual and heterosexual male gym clients regarding use of AAS and PEDs, use of alcohol and illicit drugs, seroprevalence of infectious disease, engagement in risky injection practices and sexual behaviors, and presence of psychiatric conditions. METHODS: Recruitment and data collection occurred outside four exercise gyms in the San Francisco Castro District area between October 25, 2014 and March 10, 2015. Two hundred and twenty homosexual men and 73 heterosexual men completed the 114-item cross-sectional survey. RESULTS: Ten percent of homosexual men reported lifetime AAS use. Homosexual men had almost four times more sexual partners and were over 14 times more likely to knowingly have unprotected intercourse with a known HIV positive person than heterosexual men. In addition, a quarter of homosexual men who injected drugs admitted to sharing used syringes or needles with another person. Conclusions/Importance: The current study is the first to confirm AAS use among homosexual men in the United States. Homosexual men partook in high-risk sexual behaviors and injection practices which may place them at greater risks for contracting and spreading HIV and other infectious diseases.

RESUMO

OBJECTIVE: Few studies have assessed symptoms of eating disorders in older men. METHOD: We administered anonymous questionnaires to 470 men, aged 40-75 years, in and around Innsbruck, Austria, to assess eating behavior, body image, and exercise activities. We defined current eating disorder symptoms (EDS) as (1) BMI < 18.5; (2) binge eating; (3) binge eating and purging; or (4) purging without binge eating. RESULTS: Of the 470 men, 32 (6.8%) reported one of the four eating disorder symptoms. The 32 men with eating disorder symptoms, compared to the 438 men with normal eating, showed significantly greater pathology on scales assessing eating behavior, exercise addiction, satisfaction with body shape, and weight. However, the EDE-Q cutoff score for eating disturbance identified only three (9%) of the EDS men. DISCUSSION: Symptoms of disordered eating, sometimes involving purging via excessive exercise, do occur in older men, and may be missed by conventional instruments. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:953-957).

RESUMO

Anabolic-androgenic steroids (AAS) have been linked to a range of problematic behaviors, but AAS use is still sometimes portrayed as more benign than other forms of classical drug abuse. To address this issue, we compared the prevalence of anti-social behaviors among adolescent AAS users, non-AAS illicit drug users, and drug non-users. We examined 3 waves (2004, 2008, and 2012) of self-reported cross-sectional data from a secondary school survey conducted in Stockholm, Sweden (total n = 19,773; response percentage, 79.6%). Across all survey years, the risk ratios for virtually all measured anti-social behaviors were significantly higher among AAS users compared to non-AAS illicit drug users and to drug non-users.

RESUMO

OBJECTIVE: Little is known about the prevalence and correlates of eating disorders (ED) in middle-aged women. METHOD: We mailed anonymous questionnaires to 1,500 Austrian women aged 40-60 years, assessing ED (defined by DSM-IV), subthreshold ED, body image, and quality of life. We broadly defined "subthreshold ED" by the presence of either (1) binge eating with loss of control or (2) purging behavior, without requiring any of the other usual DSM-IV criteria for frequency or severity of these symptoms. RESULTS: Of the 715 (48%) responders, 33 [4.6%; 95% confidence interval (CI): 3.3-6.4%] reported symptoms meeting full DSM-IV criteria for an ED [bulimia nervosa = 10; binge eating disorder = 11; eating disorder not otherwise specified (EDNOS) = 12]. None displayed anorexia nervosa. Another 34 women (4.8%; CI: 3.4-6.6%) displayed subthreshold ED. These women showed levels of associated psychopathology virtually equal to the women with full-syndrome diagnoses. DISCUSSION: ED appear common in middle-aged women, with a preponderance of binge eating disorder and EDNOS diagnoses as compared to the "classical" diagnoses of anorexia and bulimia nervosa. Interestingly, middle-aged women with even very broadly defined subthreshold ED showed distress and impairment comparable to women with full-scale ED.

RESUMO

BACKGROUND AND OBJECTIVES: Although various surveys have tracked the prevalence of anabolic-androgenic steroid (AAS) use in American teenagers and young adults, no recent surveys have assessed the lifetime prevalence of AAS use in Americans overall. We therefore analyzed serial youth-survey data to derive estimates of the lifetime prevalence of AAS use in the current American general population. METHODS: We first determined the distribution of age of onset of AAS use, based on pooled data from nine studies. Using this distribution, we then developed equations to project the eventual lifetime prevalence of AAS use among young survey respondents, once they aged and completed the period of risk for initiating AAS. We similarly calculated the denominator of lifetimes of risk for AAS use in the total American population. We next applied these equations to four independent national youth datasets to derive current American general-population estimates for lifetime AAS use. Finally, using data from 10 pooled studies, we estimated the lifetime prevalence of AAS dependence among AAS users. RESULTS: Age-of-onset studies consistently showed that AAS use begins later than most drugs, with only 22% of users (95% confidence interval: 19-25%) starting before age 20. Applying the age-of-onset findings to national youth datasets, we estimated that among Americans currently age 13-50 years, 2.9-4.0 million have used AAS. Within this group, roughly 1 million may have experienced AAS dependence. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Although subject to various limitations, our estimation techniques suggest a surprisinigly high prevalence of AAS use and dependence among Americans.

RESUMO

Background: Prior research has demonstrated associations between anabolic-androgenic steroid (AAS) use and features from several childhood and adolescent psychosocial domains including body image concerns, antisocial traits, and low levels of parental care. However, prior approaches have been limited by their focus on individual features and lack of consideration of the relevant causal structure. Methods: We re-analyzed data from a previous cross-sectional cohort study of 232 male weightlifters aged 18-40, of whom 101 had used AAS. These men completed retrospective measures of features from their childhood and early adolescence, including body image concerns, eating disorder psychopathology, antisocial traits, substance use, and family relationships. Using an approach informed by principles of causal inference, we applied four machine-learning methods - lasso regression, elastic net regression, random forests, and gradient boosting - to predict AAS use. Results: The four methods yielded similar receiver operating curves, mean area under the curve (range 0.66 to 0.72), and sets of highly important features. Features related to adolescent body image concerns (especially muscle dysmorphia symptoms) were the strongest predictors. Other important features were adolescent rebellious behaviors; adolescent feelings of ineffectiveness and lack of interoceptive awareness; and low levels of paternal care. Conclusions: Applying machine learning within a causally informed approach to re-analyze data from a prior study of weightlifters, we identified six factors (most prominently those related to adolescent body image concerns) as proposed causal factors for the development of AAS use. Compared with the prior analyses, this approach achieved greater methodologic rigor and yielded stronger and broader findings.

RESUMO

CONTEXT: The effect of testosterone on depressive symptoms in men with hypogonadism remains incompletely understood. OBJECTIVE: We assessed the effects of testosterone-replacement therapy (TRT) in improving depressive symptoms in hypogonadal men with and without depressive symptoms enrolled in the TRAVERSE cardiovascular safety trial. METHODS: A randomized, placebo-controlled, double-blind study was conducted at 316 trial sites. Participants included men, aged 45 to 80 years, with 2 fasting testosterone levels less than 300 ng/dL, 1 or more hypogonadal symptoms, cardiovascular disease (CVD), or increased risk of CVD. We evaluated 3 subgroups of participants: (1) men with rigorously defined, late-life-onset, low-grade persistent depressive disorder (LG-PDD, previously "dysthymia"); (2) all men with significant depressive symptoms (Patient Health Questionnaire-9 Score >4); and (3) all randomly assigned men. Intervention included 1.62% transdermal testosterone or placebo gel. Outcome measures included the proportions of participants (1) meeting criteria for LG-PDD or (2) with significant depressive symptoms; and changes in depressive symptoms, energy, sleep quality, and cognition in testosterone-treated vs placebo-treated men in the 3 subgroups. RESULTS: Of 5204 randomly assigned participants, 2643 (50.8%) had significant depressive symptoms, but only 49 (1.5%) met rigorous criteria for LG-PDD. Among those with LG-PDD, there was no significant difference in any outcome measure between the TRT and placebo groups, possibly reflecting low statistical power. In men with significant depressive symptoms (n = 2643) and in all randomly assigned participants (n = 5204), TRT was associated with modest but significantly greater improvements in mood and energy but not cognition or sleep quality. CONCLUSION: Depressive symptoms are common in middle-aged and older men with hypogonadism but LG-PDD is uncommon. TRT is associated with small improvements in mood and energy in hypogonadal men with and without significant depressive symptoms.

RESUMO

BACKGROUND: Bipolar disorder may be associated with mitochondrial dysfunction. Therefore, agents that enhance mitochondrial functioning may be efficacious in bipolar disorder. We performed a randomized placebo-controlled trial of the mitochondrial enhancers acetyl-L-carnitine (ALCAR) and α-lipoic acid (ALA) in patients with bipolar depression, and assessed markers of cerebral energy metabolism using phosphorus magnetic resonance spectroscopy. METHODS: We administered ALCAR (1000-3000 mg daily) plus ALA (600-1800 mg daily) or placebo for 12 weeks to 40 patients with bipolar depression and obtained imaging data at baseline, week 1, and week 12 of treatment in 20 patients using phosphorus 3-dimensional chemical-shift imaging at 4 T. Statistical analysis used random effects mixed models. RESULTS: We found no significant difference between ALCAR/ALA and placebo on change from baseline in the Montgomery-Asberg Depression Rating Scale in both the longitudinal (mean difference [95% confidence interval], -1.4 [-6.2 to 3.4], P = 0.58) and last-observation-carried-forward (-3.2 [-7.2 to 0.9], P = 0.12) analyses. ALCAR/ALA treatment significantly reduced phosphocreatine levels in the parieto-occipital cortex at week 12 (P = 0.002). Reduction in whole brain total nucleoside triphosphate levels from baseline to week 1 was associated with reduction in Montgomery-Asberg Depression Rating Scale scores (P = 0.02) in patients treated with ALCAR/ALA. However, this was likely a chance finding attributable to multiple statistical comparisons. CONCLUSIONS: Treatment with ALCAR and ALA at the dose and duration used in this study does not have antidepressant effects in depressed bipolar patients and does not significantly enhance mitochondrial functioning in this patient group.
