Uptake of the Australian Heart Health Check before and after the COVID-19 pandemic outbreak.

BACKGROUND AND OBJECTIVES: In 2019, a 'Heart Health Check' Medicare Benefit Schedule (MBS) item (699) was introduced to support cardiovascular risk assessment. This study sought to determine the uptake of Item 699 and changes to existing health assessment item claims, before and after the COVID­19 outbreak. METHOD: National MBS data for health assessment items were analysed for adults aged ≥35 years. RESULTS: Item 699 accounted for 9% of health assessment item claims since its introduction. Claims for pre-existing health assessment items were virtually unchanged (1% increase) after Item 699 was introduced. Overall, there were 68,967 fewer health assessment item claims (7% decrease) after the COVID-19 outbreak and Item 699 had the greatest decline in claims (27% reduction). DISCUSSION: Uptake of Item 699 accounted for 9% of health assessment item claims since its introduction. COVID-19 restrictions coincided with a decline in all health assessment item claims, particularly for Item 699.

Effects of a Mindfulness App on Employee Stress in an Australian Public Sector Workforce: Randomized Controlled Trial.

BACKGROUND: Workplace-based mindfulness programs have good evidence for improving employee stress and mental health outcomes, but less is known about their effects on productivity and citizenship behaviors. Most of the available evidence is derived from studies of mindfulness programs that use class-based approaches. Mindfulness apps can increase access to training, but whether self-directed app use is sufficient to realize benefits equivalent to class-based mindfulness programs is unknown. OBJECTIVE: We assessed the effectiveness of a mindfulness app, both with and without supporting classes, for reducing employees' perceived stress. Changes in mindfulness, mental health, quality of life, perceptions of job demand, control and support, productivity indicators, organizational citizenship, and mindful behaviors at work were also investigated. METHODS: Tasmanian State Service employees were invited by the Tasmanian Training Consortium to a 3-arm randomized controlled trial investigating the effects of a mindfulness app on stress. The app used in the Smiling Mind Workplace Program formed the basis of the intervention. The app includes lessons, activities, and guided meditations, and is supported by 4 instructional emails delivered over 8 weeks. Engagement with the app for 10-20 minutes, 5 days a week, was recommended. Reported data were collected at baseline (time point 0), 3 months from baseline (time point 1 [T1]), and at 6-month follow-up (time point 2). At time point 0, participants could nominate a work-based observer to answer surveys about participants' behaviors. Eligible participants (n=211) were randomly assigned to self-guided app use plus four 1-hour classes (app+classes: 70/211, 33.2%), self-guided app use (app-only: 71/211, 33.6%), or waitlist control (WLC; 70/211, 33.2%). Linear mixed effects models were used to assess changes in the active groups compared with the WLC at T1 and for a head-to-head comparison of the app+classes and app-only groups at follow-up. RESULTS: App use time was considerably lower than recommended (app+classes: 120/343 minutes; app-only: 45/343 minutes). Compared with the WLC at T1, no significant change in perceived stress was observed in either active group. However, the app+classes group reported lower psychological distress (ß=-1.77, SE 0.75; P=.02; Cohen d=-0.21) and higher mindfulness (ß=.31, SE 0.12; P=.01; Cohen d=0.19). These effects were retained in the app+classes group at 6 months. No significant changes were observed for the app-only group or for other outcomes. There were no significant changes in observer measures at T1, but by time point 2, the app+classes participants were more noticeably mindful and altruistic at work than app-only participants. CONCLUSIONS: Including classes in the training protocol appears to have motivated engagement and led to benefits, whereas self-guided app use did not realize any significant results. Effect sizes were smaller and less consistent than meta-estimates for class-based mindfulness training.

A systematic review and meta-analysis of workplace mindfulness training randomized controlled trials.

This meta-analytic review responds to promises in the research literature and public domain about the benefits of workplace mindfulness training. It synthesizes randomized controlled trial evidence from workplace-delivered training for changes in mindfulness, stress, mental health, well-being, and work performance outcomes. Going beyond extant reviews, this article explores the influence of variability in workforce and intervention characteristics for reducing perceived stress. Meta-effect estimates (Hedge's g) were computed using data from 23 studies. Results indicate beneficial effects following training for mindfulness (g = 0.45, p < .001) and stress (g = 0.56, p < .001), anxiety (g = 0.62, p < .001) and psychological distress (g = 0.69, p < .001), and for well-being (g = 0.46, p = .002) and sleep (g = 0.26, p = .003). No conclusions could be drawn from pooled data for burnout due to ambivalence in results, for depression due to publication bias, or for work performance due to insufficient data. The potential for integrating the construct of mindfulness within job demands-resources, coping, and prevention theories of work stress is considered in relation to the results. Limitations to study designs and reporting are addressed, and recommendations to advance research in this field are made. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Women Remain at Risk of Iodine Deficiency during Pregnancy: The Importance of Iodine Supplementation before Conception and Throughout Gestation.

In Australia, pregnant women are advised to take an iodine supplement (I-supp) (150 µg/day) to reduce risks to the foetus associated with iodine deficiency (ID). To examine the impact of this recommendation on iodine status, and to identify factors that contribute to adequacy during gestation, supplement use and Urinary Iodine Concentration (UIC) was measured in 255 pregnant women (gestation range 6 to 41 weeks) in Tasmania. The median UIC (MUIC) of 133 µg/L (Inter-quartile range 82⁻233) was indicative of ID, being below the 150⁻249 µg/L range for adequacy during pregnancy. Women taking an iodine-containing-supplement (I-supp) had a significantly higher MUIC (155 µg/L) (n = 171) compared to the combined MUIC (112.5 µg/L) (n = 84) of those who had never (120 µg/L) (n = 61) or were no longer taking an I-supp (90 µg/L) (n = 23) (p = 0.017). Among women reporting I-supp use, the MUIC of those commencing the recommended 150 µg/day prior to conception was significantly higher than those starting supplementation following pregnancy confirmation: 196 (98⁻315) µg/L (n = 45) versus 137.5 (82.5⁻233.5) µg/L (n = 124), p = 0.032. Despite recommendations for iodine supplementation pregnant Tasmanian women remain at risk of ID. Commencing an I-supp of 150 µg/day prior to conception and continuing throughout pregnancy is required to ensure adequacy. Timely advice regarding the importance of adequate iodine nutrition, including supplementation is needed to reduce the risk of irreversible in utero neurocognitive damage to the foetus.

Mild iodine deficiency during pregnancy is associated with reduced educational outcomes in the offspring: 9-year follow-up of the gestational iodine cohort.

CONTEXT: Severe iodine deficiency (ID) during gestation is associated with neurocognitive sequelae. The long-term impact of mild ID, however, has not been well characterized. OBJECTIVE: The purpose of this study was to determine whether children born to mothers with urinary iodine concentrations (UICs) <150 µg/L during pregnancy have poorer educational outcomes in primary school than peers whose mothers did not have gestational ID (UIC ≥150 µg/L). DESIGN: This was a longitudinal follow-up (at 9 years old) of the Gestational Iodine Cohort. Pregnancy occurred during a period of mild ID in the population, with the children subsequently growing up in an iodine-replete environment. SETTING AND PARTICIPANTS: Participants were children whose mothers attended The Royal Hobart Hospital (Tasmania) antenatal clinics between 1999 and 2001. MAIN OUTCOME MEASURES: Australian national curriculum and Tasmanian state curriculum educational assessment data for children in year 3 were analyzed. RESULTS: Children whose mothers had UIC <150 µg/L had reductions of 10.0% in spelling (-41.1 points, 95% confidence interval [CI], -68.0 to -14.3, P = .003), 7.6% in grammar (-30.9 points, 95% CI, -60.2 to -1.7, P = .038), and 5.7% in English-literacy (-0.33 points, 95% CI, -0.63 to -0.03, P = .034) performance compared with children whose mothers' UICs were ≥150 µg/L. These associations remained significant after adjustment for a range of biological factors (maternal age at birth of child, gestational length at time of birth, gestational age at time of urinary iodine collection, birth weight, and sex). Differences in spelling remained significant after further adjustment for socioeconomic factors (maternal occupation and education). CONCLUSIONS: This study provides preliminary evidence that even mild iodine deficiency during pregnancy can have long-term adverse impacts on fetal neurocognition that are not ameliorated by iodine sufficiency during childhood.

The airborne natural radioactivity in the uranium mine Rozná I.

The knowledge of the behaviour of radioactive aerosol particles in the uranium mine atmosphere is very important due to the evaluation of the effective dose for uranium miners. During the research of the project SUJ200402-'Study of behaviour of natural long-lived radionuclides in the mine atmosphere', several measurement campaigns were performed in the last active Central Europe uranium mine Rozna I. The main purpose of this paper is characterisation the radionuclides which creating the main part of the airborne radioactivity in the uranium mine atmosphere. The present paper introduces results of the measurements of airborne radioactivity in stopes of the uranium mine Rozna I. The measurements were performed at the 21st floor at a depth of ∼1100 m under the ground. In addition to the concentration of (222)Rn, its progenies, long-lived radionuclides and also the concentration of aerosol particles were measured.
