    ABSTRACT: We aimed to investigate antidepressant use, including the class of antidepressant, in mid-age and older Australians according to sociodemographic, lifestyle and physical and mental health-related factors. Baseline questionnaire data on 111,705 concession card holders aged ⩾45 years from the 45 and Up Study-a population-based cohort study from New South Wales, Australia-were linked to administrative pharmaceutical data. Current- and any-antidepressant users were those dispensed medications with Anatomical Therapeutic Chemical classification codes beginning N06A, within ⩽6 months and ⩽19 months before baseline, respectively; non-users had no antidepressants dispensed ⩽19 months before baseline. Multinomial logistic regression was used to calculate adjusted relative risk ratios (aRRRs) for predominantly self-reported factors in relation to antidepressant use. Some 19% of the study population (15% of males and 23% of females) were dispensed at least one antidepressant during the study period; 40% of participants used selective serotonin reuptake inhibitors (SSRIs) only and 32% used tricyclic antidepressants (TCAs) only. Current antidepressant use was markedly higher in those reporting: severe versus no physical impairment (aRRR 3.86(95%CI 3.67-4.06)); fair/poor versus excellent/very good self-rated health (4.04(3.83-4.25)); high/very high versus low psychological distress (7.22(6.81-7.66)); ever- versus never-diagnosis of depression by a doctor (18.85(17.95-19.79)); low-dose antipsychotic use versus no antipsychotic use (12.26(9.85-15.27)); and dispensing of ⩾10 versus <5 other medications (5.97(5.62-6.34)). Sociodemographic and lifestyle factors were also associated with use, although to a lesser extent. Females, older people, those with lower education and those with poorer health were more likely to be current antidepressant users than non-users and were also more likely to use TCAs-only versus SSRIs-only. Use of antidepressants is substantially higher in those with physical ill-health and in those reporting a range of adverse mental health measures. In addition, sociodemographic factors, including sex, age and education were also associated with antidepressant use and the class of antidepressant used. © The Royal Australian and New Zealand College of Psychiatrists 2014.

    ABSTRACT: Objective : We sought to test the hypothesis that eating-disordered behavior (EDB) is associated with comparable levels of impairment in psychosocial functioning in men and women. Method: Postal questionnaires that assessed EDB (binge eating, purging, extreme dietary restriction, excessive exercise and weight/shape overvaluation) and psychosocial impairment (general psychological distress, life satisfaction and social support) were completed by a general population sample of men (n = 1011) and women (n = 1897). Results: Binge eating, purging and overvaluation were associated with comparable levels of psychosocial impairment for both men and women and this was the case for each of the three measures of psychosocial functioning employed. Extreme dietary restriction was associated with greater psychosocial impairment in women than in men, whereas excessive exercise was not associated with psychosocial impairment in either women or men. Conclusions: There appear to be few differences between men and women in terms of psychosocial impairment associated with EDB. It may no longer be appropriate to base the development of eating disorder prevention programs on the premise that EDB is primarily a problem of women. Health professionals may be more likely to see more men with EDB in their practices in the future.

    ABSTRACT: Objectives: To examine the relationships of retirement and reasons for retirement with psychological distress in men and women at the age of 45-79 years. Method: Data from 202,584 Australians participating in the large-scale 45 and Up Study was used. Psychological distress was measured by the Kessler psychological distress scale. Associations between different work status and reasons for retirement with psychological distress were assessed for men and women at different ages using logistic regression. Results: Being fully retired or unemployed was associated with the high levels of psychological distress compared to being in paid work for men and women aged 45-64 (p < 0.0001), and for men aged 65-74 years (p ≤ 0.0014). At the age of 75-79 years, there was no difference in psychological distress between different work statuses. Among retirees, retirement due to ill health, being made redundant or caring duty was associated with the high level of psychological distress. Conclusion: The association between work and mental health underscores the importance of policies and strategies to encourage and enable people to continue in the workforce after age 55, particularly for men. Important reasons for retirement with worse mental health outcomes include redundancy, ill health and needing to care for family or a friend. These circumstances will affect whether a person can continue working and their risk of poor mental health, and both considerations should be addressed in developing approaches for maintaining older workers or assisting them with their retirement transition.

    ABSTRACT: Objective We examined the relative importance of physical health status, weight/shape concerns, and binge eating as mediators of the association between obesity and psychosocial impairment in a community sample of women and men.Method Self-report measures of eating disorder features, perceived physical health and psychosocial functioning were completed by a general population sample of women and men classified as obese or non-obese (women: obese=276, non-obese=1220; men: obese=169, non-obese=769). Moderated mediation analysis was used to assess the relative importance of each of the putative mediators in accounting for observed associations between obesity and each outcome measure and possible moderation of these effects by sex.ResultsWeight/shape concerns and physical health were equally strong mediators of the association between obesity and psychosocial impairment. This was the case for both men and women and for each of three measures of psychosocial functioning - general psychological distress, life satisfaction and social support - employed. The effects of binge eating were modest and reached statistical significance only for the life satisfaction measure in men.ConclusionA greater focus on body acceptance may be indicated in obesity prevention and weight-management programs.International Journal of Obesity accepted article preview online, 11 June 2014; doi:10.1038/ijo.2014.100.

    ABSTRACT: Understanding attitudes to mental health issues can inform public health interventions. However, low response rates may contribute to nonresponse bias. We examined the effect of a prenotification postcard and a short message (teaser) on response rates to a mailed questionnaire about bulimia nervosa "mental health literacy." Questionnaires were mailed to 3,010 adults (50.6% female and 49.4% male) aged 18-65 years. Procedures were varied according to sending prenotification before the questionnaire and the placement of a teaser on the survey envelope. Outcomes considered were response rate, response time, and cost. The overall response rate was 22.0%. Significant main effects showed higher response rates for the use of prenotification, among female participants, and older participants. A significant interaction of teaser by gender indicated lower response rates for men who received the teaser but not for women. Older participants returned the questionnaire more promptly than younger participants. Females-but not males-who received the teaser were slower to return the questionnaire. Higher response rates for participants receiving the postcard compensated for increased costs, particularly for males and older participants. Response rates to a mental health postal survey can be increased through the use of prenotification.

    ABSTRACT: The overvaluation of weight and/or shape ("overvaluation"), a diagnostic criterion for anorexia nervosa and bulimia nervosa, is increasingly supported for inclusion in the Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-5) criteria of binge eating disorder (BED). However, current evidence has been largely confined to adult populations. The current study aims to examine the status of overvaluation among adolescents with loss of control (LOC) eating recruited from a large, population-based sample.

    ABSTRACT: Stigmatizing attitudes towards eating disorders negatively impacts treatment seeking. To determine the effect of interventions to reduce stigma, a measure of stigma that is simple to implement is required. This study aimed to develop a measure of stigmatizing attitudes and beliefs towards bulimia nervosa (SAB-BN) and evaluate the distribution of beliefs across gender, age, education, and income groups. Participants were 1828 community adults (890 men; 938 women) aged 18-65 sampled from the Australian Electoral Roll responded to a mailed questionnaire. Participants provided demographic information and completed the SAB-BN questionnaire. Five components of stigmatizing attitudes and beliefs were identified; advantages of BN, minimization/low seriousness, unreliability, social distance, and personal responsibility. Stigma was low except on social distance and personal responsibility sub-scales, which indicated negative attitudes toward people with bulimia. Men compared with women and lower compared with higher education and income groups held significantly higher stigmatizing attitudes and beliefs. There were few differences between age groups in stigma. Differences between demographic groups provides evidence for known-groups validity. The SAB-BN questionnaire provides a potentially useful tool for evaluating stigma in relation to BN. Results provide insight into components of stigma and the demographic groups to whom interventions should be targeted. © 2013 Wiley Periodicals, Inc. Int J Eat Disord 2013 (Int J Eat Disord 2013).

    ABSTRACT: In order to elucidate the individual and community health burden of body dissatisfaction (BD), we examined impairment in quality of life associated with BD in a large, general population sample of women. Self-report measures of BD, health-related quality of life (SF-12 Physical and Mental Component Summary scales) and subjective quality of life (WHOQOL-BREF Psychological Functioning and Social Relationships subscales) were completed by 5,255 Australian women aged 18 to 42 years. Most participants (86.9%) reported some level of dissatisfaction with their weight or shape and more than one third (39.4%) reported moderate to marked dissatisfaction. Higher levels of BD were associated with poorer quality of life for all items of both quality of life measures, the degree of impairment being proportional to the degree of BD. Associations were strongest for items tapping mental health and psychosocial functioning, although greater BD was associated with substantially increased risk of impairment in certain aspects of physical health even when controlling for body weight. Post-hoc analysis indicated that the observed associations between BD and quality of life impairment were not accounted for by an association between BD and eating disorder symptoms. In women, BD is associated with marked impairment in aspects of quality of life relating to mental health and psycho-social functioning and at least some aspects of physical health, independent of its association with body weight and eating disorder symptoms. Greater attention may need to be given to BD as a public health problem. The fact that BD is "normative" should not be taken to infer that it is benign.

    ABSTRACT: The relationship between comorbidity and psychological distress is well documented, however the mechanism of this association is unclear. We aim to assess the extent to which the association between common chronic conditions and high scores on the Kessler Psychological Distress Scale (K10) measure of psychological distress vary according to comorbid conditions, disability, and sociodemographic circumstances. Analysis of self-reported cross-sectional data from the New South Wales 45 and Up Study, Australia, for 236,508 participants aged 45 years and over, using logistic regression modeling. Self-reported heart attack/angina, other heart disease, stroke, and diabetes were all significantly associated with higher risk of high/very high K10 scores. These associations were attenuated, but remained statistically significant, when comorbidity, disability, and sociodemographic factors were added to the model. Men reporting needing help for daily tasks were nine times as likely to report high/very high K10 scores as those without this need, and women reporting needing help were seven times more likely to have high/very high K10 scores. Heart attack/angina, other heart disease, stroke, and diabetes are all significantly associated with psychological distress. However, these effects are partly explained by other comorbid conditions, limitations on physical functioning, and sociodemographic factors. These findings highlight the importance of developing public health policies that encompass psychological, physiological, and social domains, and provide crucial insights for clinicians in identifying and supporting those people at risk of psychological distress.

    ABSTRACT: This study investigated the factors associated with initiating cannabis use, reverting to cannabis use and remaining a cannabis user in young adulthood. This is an important area of research as the risk for cannabis initiation is extending beyond adolescence and opportunities to influence cannabis use pathways can emerge throughout the life-course. A large, community-based sample was followed prospectively. Data from two successive waves (mean age 23 years and 27 years respectively) of the Path Through Life Study (PATH) were analysed (n=2045). The longitudinal design enabled change in cannabis use in young adulthood to be predicted based on factors assessed approximately four years prior. An environment of licit drug use was strongly associated with initiating cannabis use (tobacco: OR=4.98, 95%CI: 2.31-10.76) and reverting to cannabis use in young adulthood (alcohol: OR=2.13, 95%CI: 1.42-3.19). Greater fun seeking was found to orientate people towards initiating cannabis use in young adulthood (OR=1.17, 95%CI: 1.04-1.30). Higher psychoticism increased the odds of remaining a cannabis user (OR=1.19, 95%CI: 1.07-1.33). Religious involvement was protective of cannabis initiation (OR=0.89, 95%CI: 0.83-0.95). Early childhood factors did not influence the pattern of cannabis use in young adulthood. The findings make an important contribution to the development of prevention and intervention strategies for young adults by drawing attention to specific areas of risk and protection.

    ABSTRACT: Prevailing child psychopathology paradigms focus on caregiving in isolation from market work. Yet most children's caregivers - mothers and fathers - are also employed. Although policy and academic debate has voiced concerns that employment could hamper mothers' capacity to care, less emphasis is given to the benefits generated by mothers' jobs. By contrast, theories of child mental health often view fathers' employment as beneficial, indeed necessary, for children's wellbeing, and few problematise fathers' capacity to combine work and care. This paper aims to integrate these seemingly contradictory concerns. We consider whether mothers' and fathers' rewards from combining employment with childcare may be protective for children's mental health, and whether their conflicts and dilemmas generate risks. Analyses use cross-sectional data from a representative survey of families with 4-5 year old children (Growing Up in Australia Study). We restricted our sample to employed parents (N = 2809 mothers; 3982 fathers), using data gathered in 2004. While a majority of parents reported benefits and rewards from working (work-family facilitation), more than one third also reported difficulties and conflicts (work-family conflict). When mothers or fathers experienced conflict we found elevations in young children's emotional and behavioural symptoms, with the risks compounding if both parents experienced conflict between work and family. Associations persisted after adjusting for family socioeconomic circumstances and composition, and they were not offset by work-family facilitation. We did not find evidence for heightened vulnerability to work-family conflict in families with few socioeconomic resources. However, among these disadvantaged families we observed stronger protective associations with children's mental health when parents had rewarding and supportive jobs. Our study extends current paradigms of child mental health by considering the interplay between care environments and market work. Jobs which help mothers and fathers to combine employment with caregiving could yield health benefits across generations.

    ABSTRACT: Most studies of children’s development and parents’ wellbeing have not dealt effectively with the complexity of multiple disadvantage. Traditional approaches have typically used a limited set of outcomes and predictors. Even studies utilizing multiple risk factors have often treated these as confounders, adjusting for their influence, while concentrating on a primary association of interest. Such strategies do not illuminate the real world essence of disadvantage, i.e. that adversities co-occur more than expected by chance and that multiple disadvantage is common. The main aim of the present paper is to address this neglected topic and develop summary measures of adversity using the 2004–2005 data from Wave 1 of the Longitudinal Study of Australian Children. Information was obtained from families of 5,107 babies (0–1 years) and families of 4,983 children (4–5 years). The prevalence of multiple disadvantage among families with young children and the degree to which summary adversity measures are associated with each other and with family and child outcomes is then estimated. Using factor analysis, 12 lower-order constructs and two higher-order components of adversity were developed, labelled (1) material and (2) psychosocial adversity. Findings show that the two component scores were more strongly associated with outcomes than were the more specific construct scores and that psychosocial adversity was somewhat more relevant to family wellbeing and child development than material adversity.

    ABSTRACT: Studies of quality of life among individuals with eating disorders have relied almost exclusively on clinical samples. We examined impairment in quality of life in a community sample of women with eating disorders recruited as part of an epidemiological study. Measures of health-related quality of life (Medical Outcomes Study 12-item Short-Form Physical and Mental Component Summary scales) and subjective well-being (WHOQOL-BREF Psychological Functioning and Social Relationships subscales) were completed by women with eating disorders (n = 159), primarily variants of bulimia nervosa and binge eating disorder, and a comparison group of healthy women (n = 232). When compared with healthy women, women with eating disorders reported substantial impairment in aspects of quality of life relating to mental health, although item-level analysis indicated considerable variation in the extent to which specific aspects of emotional well-being were affected. Impairment in social relationship and in physical health was less pronounced and due, at least in part, to between-group differences in age, body weight and demographic characteristics. Impairment in certain aspects of perceived physical health was, however, apparent among women with eating disorders, even after controlling for between-group differences in body weight. Community cases of women with eating disorders experience marked impairment in quality of life as this relates to mental health functioning and at least some impairment in physical health functioning. Personality characteristics and ego-syntonic aspects of eating-disordered behaviour may complicate the interpretation of findings relating to impairment in specific aspects of quality of life.

    ABSTRACT: We conducted a prospective exploration of the temporal course of eating disorder (ED) symptoms in two cohorts of community women. One hundred and twenty-two young women (Cohort 1) identified in a general population based survey with ED symptoms of clinical severity agreed to participate in a 5-year follow-up study. A comparative sample (Cohort 2) of 706 similar aged self-selected college women (221 with disordered eating) was recruited one year later. Both ED groups were given a health literacy package in the first year. ED symptoms, health related quality of life, and psychological distress were assessed annually with the Eating Disorder Examination Questionnaire, the Short Form-12 Health Survey and the Kessler Psychological Distress Scale, respectively. Forty percent (Cohort 1) and 30.3% (Cohort 2) completed questionnaires at each year of follow-up. In both groups, there was early improvement in ED symptoms which plateaued after the first year, and participants retained high EDE-Q scores at 5 years. BMI increased as expected. Mental health related quality of life scores did not change but there were small improvements in psychological distress scores. The findings suggest little likelihood of spontaneous remission of ED problems in community women.

    ABSTRACT: Australian families work and raise children in different contexts from those of families 50 or even 30 years ago. Technology, globalisation, flexible and deregulated labour markets, and the unprecedented movement of mothers back into the labour force have rewritten the way work and family interconnect. At the same time, what constitutes adequate parenting has been redefined in novel and demanding ways. New knowledge is needed to understand what the convergence of these changes means for the wellbeing of parents and their children. Work experiences and parenting expectations have been revolutionised. Most children now grow up within the confines of nuclear families focused on children’s developmental needs. Bringing up children was once the business of large, multigenerational families and their local communities and is now seen as the responsibility of parents. At the same time global competition, increased labour flexibility, and the shift to service and knowledge economies has placed new pressures on working life. Employed parents must combine working with providing care for children and are therefore facing increased expectations and demands from both work and family spheres.

    ABSTRACT: This study examines measures of psychosocial job quality developed from the Household Income and Labour Dynamics in Australia (HILDA) Survey, and reports on associations with physical and mental health. The study used seven waves of data from the HILDA Survey with 5,548 employed respondents. Longitudinal random-intercept regression models assessed the association of time-varying and between-person measures of psychosocial job quality job adversity with physical and mental health. Respondents' specific experience of psychosocial job adversity, except marketability, was associated with increased risk of mental health problems, whereas the association between psychosocial job adversity and physical health was largely driven by differences between people. Moving into jobs with different psychosocial quality is associated with changes in mental health. In contrast, individuals with poor physical health show an increased propensity to work in poor-quality jobs but it seems that changes in physical health are not as strongly tied to changes in job quality. Differences in the relationship between physical and mental health and psychosocial job quality have implications for the design of employment, health and social policy. The HILDA Survey is an important resource for policy development in Australia, and the availability of valid measures of psychosocial of job quality will enhance its use to better understand this important determinant and correlate of health.

    ABSTRACT:  Impairment in mental health associated with eating-disorder features was examined in a large, general population sample of women aged 18 to 42 years.  Participants (n = 5255) completed self-report measures of eating-disordered behaviour, mental health functioning, height and weight and socio-demographic information. The most common eating-disorder features were extreme concerns about weight or shape (14.6%), subjective overeating (12.7%), objective overeating (10.6%) and extreme concerns about dietary intake (10.4%). In multivariable analysis, in which mental health functioning was regressed on eating-disorder features, while also controlling for age and body weight, objective overeating (β  =  -0.07), subjective overeating (β   = -0.07), extreme dietary restriction (β  =  -0.06) and extreme concerns about eating (β  =  -0.04) showed small, but statistically significant associations with mental health impairment, whereas extreme weight or shape concerns showed a very strong association (β  =  -0.24). From a clinical perspective, the findings are consistent with the importance attached to the "over-evaluation" of weight or shape as a core component of eating-disorder psychopathology. From a public health perspective, the findings indicate the need to conceive of body dissatisfaction as a target for health promotion in its own right.

    ABSTRACT: We sought to evaluate the hypothesis that mental health impairment in underweight women, where this occurs, is due to an association between low body weight and elevated levels of body dissatisfaction and/or eating-disordered behaviour. Subgroups of underweight and normal-weight women recruited from a large, general population sample were compared on measures of body dissatisfaction, eating-disordered behaviour and mental health. Underweight women had significantly greater impairment in mental health than normal-weight women, even after controlling for between-group differences in demographic characteristics and physical health. However, there was no evidence that higher levels of body dissatisfaction or eating-disordered behaviour accounted for this difference. Rather, underweight women had significantly lower levels of body dissatisfaction and eating-disordered behaviour than normal-weight women. The findings suggest that mental health impairment in underweight women, where this occurs, is unlikely to be due to higher levels of body dissatisfaction or eating-disordered behaviour. Rather, lower levels of body dissatisfaction and eating-disordered behaviour among underweight women may counterbalance, to some extent, impairment due to other factors.
