RESUMO
BACKGROUND: Single time-point assessments of psychological distress are often used to indicate chronic mental health problems, but the validity of this approach is unclear. The aims of this study were to investigate how a single assessment of distress relates to longer-term assessment and quantify misclassification from using single measures to indicate chronic distress. METHODS: Data came from the Household, Income and Labour Dynamics in Australia Survey, a nationally representative study of Australian adults. Psychological distress, measured with the Kessler10 and categorised into low (scores:10- < 12), mild (12- < 16), moderate (16- < 22) and high (22-50), has been assessed in the Survey biennially since wave 7. Among respondents who were aged ≥25 years and participated in all waves in which distress was measured, we describe agreement in distress categories, and using a mixed linear model adjusting for age and sex we estimate change in scores, over a two-, four-, six- and eight-year follow-up period. We applied weights, benchmarked to the Australian population, to all analyses. RESULTS: Two-years following initial assessment, proportions within identical categories of distress were 66.0% for low, 54.5% for mild, 44.0% for moderate and 50.3% for high, while 94.1% of those with low distress initially had low/mild distress and 81.4% with high distress initially had moderate/high distress. These patterns did not change materially as follow-up time increased. Over the full eight-year period, 77.3% of individuals with high distress initially reported high distress on ≥1 follow-up occasion. Age-and sex- adjusted change in K10 scores over a two-year period was 1.1, 0.5, - 0.7 and - 4.9 for low, mild, moderate and high distress, respectively, and also did not change materially as follow-up time increased. CONCLUSION: In the absence of repeated measures, single assessments are useful proxies for chronic distress. Our estimates could be used in bias analyses to quantify the magnitude of the bias resulting from use of single assessments to indicate chronic distress.

BACKGROUND: Employment participation of mothers of young children has steadily increased in developed nations. Combining work and family roles can create conflicts with family life, but can also bring enrichment. Work-family conflict and enrichment experienced by mothers may also impact children's home environments via parenting behaviour and the couple relationship, particularly in the early years of parenting when the care demands for young children is high. METHODS: In order to examine these associations, while adjusting for a wide range of known covariates of parenting and relationship quality, regression models using survey data from 2151 working mothers of 4- to 5-year-old children are reported. RESULTS/CONCLUSION: Results provided partial support for the predicted independent relationships between work-family conflict, enrichment and indicators of the quality of parenting and the couple relationship.

Time is a resource for health, and when time is constrained, people have less opportunity to maintain good health. This study focuses on the relationship between paid work hours (with a focus on long hours) and body weight for Australian men and women. Time is conceptualised as a 24-hour system, including time in paid work, time in unpaid work, and discretionary time (available for health promoting activities). We propose that to accurately estimate the relationship between long paid work hours and body weight, analyses need to take account of unpaid work hours, and that this is particularly important for women. Analyses utilised 16 waves of data from the Household, Income and Labour Dynamics in Australia (HILDA) panel study, with data on hours in paid and unpaid work and BMI at all waves (n = 113,084 observations, 54,664 from women and 58,424 from men). We used Mixed Effects models with a Two Stage Residual Inclusion (2SRI) approach to account for time unobserved heterogeneity and the reciprocity between time uses (paid and unpaid) and body weight. The results showed that for every 10 hours worked above the gender-specific average, women weighed 762 grms more and men weighed 1.34 kgs more. When the analyses were restricted to sedentary jobs this increased to 938 grms for women and 1.68 kgs for men. We contribute new evidence highlighting the importance of including unpaid work hours in research that aims to understand working time and health.
RESUMO
OBJECTIVES: Although employment is associated with health benefits over unemployment, the psychosocial characteristics of work also influence health. We used longitudinal data to investigate whether the benefits of having a job depend on its psychosocial quality (levels of control, demands and complexity, job insecurity, and unfair pay), and whether poor quality jobs are associated with better mental health than unemployment. METHOD: Analysis of seven waves of data from 7,155 respondents of working age (44,019 observations) from a national household panel survey. Longitudinal regression models evaluated the concurrent and prospective association between employment circumstances (unemployment and employment in jobs varying in psychosocial job quality) and mental health, assessed by the MHI-5. RESULTS: Overall, unemployed respondents had poorer mental health than those who were employed. However the mental health of those who were unemployed was comparable or superior to those in jobs of the poorest psychosocial quality. This pattern was evident in prospective models: those in the poorest quality jobs showed greater decline in mental health than those who were unemployed (B = 3.03, p<0.05). The health benefits of becoming employed were dependent on the quality of the job. Moving from unemployment into a high quality job led to improved mental health (mean change score of +3.3), however the transition from unemployment to a poor quality job was more detrimental to mental health than remaining unemployed (-5.6 vs -1.0). CONCLUSIONS: Work of poor psychosocial quality does not bestow the same mental health benefits as employment in jobs with high psychosocial quality.

Objective: Children of immigrants from low-and-middle-income countries show excess overweight/obesity risk relative to host populations, possibly due to socioeconomic disadvantage. The present study was conducted to estimate overweight/obesity prevalence and its association with the family socioeconomic-position in 2-11-year-old Australian-born children of immigrants and Australian-mothers. Methods: A cross-sectional analysis of 10-year data from the Longitudinal Study of Australian Children was undertaken. Overweight/obesity was defined according to the International Obesity Taskforce, age-and sex-specific BMI cut-off-points. Results: Approximately 24% children aged 2-3 years (22% sons, and 25% daughters), were overweight/obese with no significant difference between children of immigrants and Australian-mothers. Overweight/obesity prevalence consistently increased with age for sons of mothers from low-and-middle-income countries but not daughters. Adjusting for the family socioeconomic-position did not explain excess overweight/obesity in children of mothers from low-and-middle-income countries. The odds of overweight/obesity in sons were significantly higher at 8-9 years (OR 1.5; p = 0.03) and 10-11 years (OR 1.5; p = 0.03) and in daughters at 4-5 years (OR 1.7; p = 0.002) when the mothers were from low-and-middle-income countries. Conclusion: Excess weight in children of immigrants is not due to socioeconomic disadvantage alone. Other social processes and interactions between immigrants and host cultures may be involved.
RESUMO
This qualitative study involved focus groups with 132 children and 12 parents in primary and secondary schools in metropolitan and regional areas of Victoria, Australia, to explore experiences and perceptions of children's independent mobility. The study highlights the impact of family routines, neighborhood characteristics, social norms and reference points for decision making. Children reported a wider range of safety concerns than parents, including harm from strangers or traffic, bullying, or getting lost. Children expressed great delight in being independent, often seeking to actively influence parents' decision making. Children's independent mobility is a developmental process, requiring graduated steps and skill building.

Work-family conflict (WFC) occurs when work or family demands are 'mutually incompatible', with detrimental effects on mental health. This study contributes to the sparse longitudinal research, addressing the following questions: Is WFC a stable or transient feature of family life for mothers and fathers? What happens to mental health if WFC increases, reduces or persists? What work and family characteristics predict WFC transitions and to what extent are they gendered? Secondary analyses of 5 waves of data (child ages 4-5 to 12-13 years) from employed mothers (n = 2693) and fathers (n = 3460) participating in the Longitudinal Study of Australian Children were conducted. WFC transitions, across four two-year intervals (Waves 1-2, 2-3, 3-4, and 4-5) were classified as never, conscript, exit or chronic. Significant proportions of parents experienced change in WFC, between 12 and 16% of mothers and fathers for each transition 'type'. Parents who remained in chronic WFC reported the poorest mental health (adjusted multiple regression analyses), followed by those who conscripted into WFC. When WFC was relieved (exit), both mothers' and fathers' mental health improved significantly. Predictors of conscript and chronic WFC were somewhat distinct for mothers and fathers (adjusted logit regressions). Poor job quality, a skilled occupation and having more children differentiated chronic fathers' from those who exited WFC. For mothers, work factors only (skilled occupation; work hours; job insecurity) predicted chronic WFC. Findings reflect the persistent, gendered nature of work and care shaped by workplaces, but also offer tailored opportunities to redress WFC for mothers and fathers. We contribute novel evidence that mental health is directly influenced by the WFC interface, both positively and negatively, highlighting WFC as a key social determinant of health.

OBJECTIVE: To examine independent associations of job strain (high demands and low control) and job insecurity with mental and physical health outcomes. DESIGN: Cross sectional general population study conducted in 2000 using a self completed questionnaire. SETTING: Two adjoining cities in south east Australia. SUBJECTS: 1188 employed professionals, aged 40-44 years, 55% (n = 655) male. MAIN OUTCOME MEASURES: Depression, anxiety, physical, and self rated health (SRH). RESULTS: Adverse job conditions were relatively prevalent as 23% of the sample reported high job strain, while 7.3% and 23% reported high and moderate job insecurity respectively. Associations between job conditions and health persisted after adjustment for gender, education, marital status, employment status, major life events, and negative affectivity (personality). When adjusted for job strain, high job insecurity was independently associated with a greater than threefold increase in odds for poor SRH, depression and anxiety (OR (95% confidence intervals) poor SRH: 3.72 (1.97 to 7.04) depression: 3.49 (1.90 to 6.41), anxiety: 3.29 (1.71 to 6.33)), and a twofold increase for physical health 2.19 (1.21 to 3.95). High job strain also showed significant independent associations with depression: 2.54 (1.34 to.4.75) and anxiety: 3.15 (1.48 to 6.70). CONCLUSION: In this relatively privileged socioeconomic group, insecure employment and high job strain showed independent, consistent, and strong associations with physical and mental health. These adverse job conditions are on the increase, particularly insecure employment, and the influence of these two work conditions are an important focus for future public health research and their prevalence and impact should be examined in other occupations.
