Identify the perceived benefit of mental health service use for two adolescent populations: (i) those who had considered getting help from a mental health service but had not yet done so, and (ii) those who had previously contacted or accessed a mental health service but not continued with care. Cross-sectional online survey of adolescents aged 14–18 years currently residing in Perth, Western Australia. Those who had previously accessed a mental health service but not continued with care often had less favourable perceptions of service benefit. Participants in both populations considered that mental health service use was least likely to be beneficial for conduct-related behaviours. Participants in both population groups from single-carer households or identifying as LGBTIQ reported a higher perceived benefit of mental health services. Our study highlights potential gaps in adolescent knowledge regarding mental health help-seeking. Perceptions of service benefit were often no different or less favourable amongst those who had previously accessed a mental health service but not continued with care. The range of sociodemographic factors significantly associated with perceived benefit across both populations in the sample indicates subpopulations of young people may require extra support within the system.

Issues Addressed: To explore adolescents' experiences of access to and continued use of mental health services, and identify factors influencing their perceived satisfaction with their care. This paper focusses on the role of organisational and policy-level factors in the mental health system.Method: Qualitative semi-structured face-to-face interviews with 22 adolescents aged 14-18 years living in Perth, Western Australia.Results: Adolescents identified key policy, systemic and service-based factors which influenced their access to and continued use of mental health services. These were strongly related to the processes of service intake, level of orientation towards person-centred care and adequacy of service resourcing and funding. Areas of concern for adolescents included, complex service intake procedures, suboptimal mental health service environments, lack of client-centred care and the quality of mental health support provided in school settings.Conclusions: Our research has identified a wide spectrum of factors influencing mental health service access and use amongst adolescents. The findings further support the growing national consensus for major reform to address the mental health needs of this age group. The current strengths within mental health services and the system identified by adolescents need to be supported and extended. SO WHAT?: Although there have been numerous recommendations on ways to improve mental health service access and ongoing engagement for Australian adolescents, a number of the major challenges faced by this high-risk population have shown little improvement. The findings of this research indicate the importance of now moving towards implementing meaningful plans for action. [ABSTRACT FROM AUTHOR]

The aim of this study is to identify factors that stopped, discouraged or delayed mental health help-seeking in adolescents. An Online survey of 113 adolescents aged 14–18 years old, living in Perth, Western Australia, was conducted. For participants who had not yet accessed a mental health service, the top barrier was 'Having no-one who could help me get professional care' (62%). For participants who had previously accessed a mental health service, the top barrier was 'Previous experiences with a mental health service were not helpful' (63%). Major reported barriers in this population included financial costs, negative past experiences and having no one to help access professional care. [ABSTRACT FROM AUTHOR]

A characterization of pesticides in secondary treated effluent (STE) and a screening health risk assessment were conducted to evaluate potential health impacts of recycled water for potable reuse. Samples of STE were examined pre- and post-reverse osmosis (RO) treatment in two plants. Risk quotients (RQ) were estimated by expressing the maximum and median concentration as a function of the health value. Of 128 pesticides analyzed, 11 were detected in STE. Trifluralin was detected in 86.5% of the STE samples followed by metolachlor (67.6%), 2,4-D (50%), and propiconazole (42.5%). Metolachlor was the only pesticide detected post-RO in one sample (0.08 μg/L, limit of reporting = 0.05 μg/L). RQ(max) were all below health values in the STE with the exception of thiophanate methyl (RQ max = 2.4). RO was able to reduce the concentration of all pesticides below LOR. Median removal efficiency for RO ranged from 67.1% (atrazine) to 98.8% (2,4-D). The results indicate that, despite the detection of pesticides in STE, the impact on indirect potable reuse is negligible due to the low concentrations in STE and their subsequent removal during RO treatment. Implementation of risk management strategies to optimize safety and recommendations for a monitoring program are also discussed. [ABSTRACT FROM AUTHOR]

Background: This study had two principal objectives: (i) to investigate the relationship between asthma severity and proximity to major roadways in Perth, Western Australia; (ii) to demonstrate a more accurate method of exposure assessment for traffic pollutants using an innovative GIS-based measure that fully integrates all traffic densities around subject residences. Methods: We conducted a spatial case-control study, in which 'cases' were defined as individuals aged under 19 years of age with more severe asthma (defined here as two or more emergency department contacts with asthma in a defined 5-year period) versus age- and gender-matched 'controls' with less severe asthma (defined here as one emergency department contact for asthma). Traffic exposures were measured using a GIS-based approach to determine the lengths of the roads falling within a buffer area, and then multiplying them by their respective traffic counts. Results: We examined the spatial relationship between emergency department contacts for asthma at three different buffer sizes: 50 metres, 100 metres and 150 metres. No effect was noted for the 50 metre buffer (OR = 1.07; 95% CI: 0.91-1.26), but elevated odds ratios were observed with for crude (unadjusted) estimates OR = 1.21 (95% CI: 1.00-1.46) for 100 metre buffers and OR = 1.25 (95% CI: 1.02-1.54) for 150 metre buffers. For adjusted risk estimates, only the 150 metre buffer yielded a statistically significant finding (OR = 1.24; 95% CI:1.00-1.52). Conclusions: Our study revealed a significant 24% increase in the risk of experiencing multiple emergency department contacts for asthma for every log-unit of traffic exposure. This study provides support for the hypothesis that traffic related air pollution increases the frequency of health service contacts for asthma. This study used advanced GIS techniques to establish traffic-weighted buffer zones around the geocoded residential location of subjects to provide an accurate assessment of exposure to traffic emissions, thereby providing a quantification of the ranges over which pollutants may exert a health effect.

The article presents an analysis of traffic-related air pollution and emergency department presentations for asthma in Perth, Western Australia. The researchers wanted to determine whether changes in 24-hour average background ozone, nitrogen dioxide, carbon monoxide and particulates increase the risk of emergency department (ED) presentations for asthma among children. The analysis reveals that patients aged 4 years and below exposed to nitrogen dioxide and carbon monoxide are at risk of asthma.

BACKGROUND: By international standards, water supplies in Perth, Western Australia, contain high trihalomethane (THM) levels, particularly the brominated forms. Geographic variability in these levels provided an opportunity to examine cross-city spatial relationships between THM exposure and rates of birth defects (BDs). OBJECTIVES: Our goal was to examine BD rates by exposure to THMs with a highly brominated fraction in metropolitan locations in Perth, Western Australia. METHODS: We collected water samples from 47 separate locations and analyzed them for total and individual THM concentrations (micrograms per liter), including separation into brominated forms. We classified collection areas by total THM (TTHM) concentration: low (< 60 µg/L), medium (> 60 to < 130 µg/L), and high (≥ 130 µg/L). We also obtained deidentified registry-based data on total births and BDs (2000-2004 inclusive) from post codes corresponding to water sample collection sites and used binomial logistic regression to compare the frequency of BDs aggregately and separately for the TTHM exposure groups, adjusting for maternal age and socioeconomic status. RESULTS: Total THMs ranged from 36 to 190 µg/L. A high proportion of the THMs were brominated (on average, 92%). Women living in high-TTHM areas showed an increased risk of any BD [odds ratio (OR) = 1.22; 95% confidence interval (CI), 1.01--1.48] and for the major category of any cardiovascular BD (OR = 1.62; 95% CI, 1.04--2.51), compared with women living in low-TTHM areas. CONCLUSIONS: Brominated forms constituted the significant fraction of THMs in all areas. Small but statistically significant increases in risks of BDs were associated with residence in areas with high THMs. [ABSTRACT FROM AUTHOR]

Objective: We sought to investigate seasonal variation in fetal growth, accounting for important sociodemographic, biological, and environmental exposures. Study Design: Records of births 1998 through 2006 in Perth, Western Australia were obtained (N = 147,357). We investigated small for gestational age and sex and the proportion of optimal birthweight (POBW) in relation to seasonal exposures (season, temperature, sunlight) by trimester of pregnancy. Adjustment was made for a wide range of risk factors. Results: The POBW for neonates with third trimesters predominantly in summer was 0.18% (0.00-0.36%) lower than for those in winter. POBW decreased by 0.14% (0.01-0.27%) per interquartile range increase in third-trimester temperature (9.15°C). An interquartile range increase in temperature over pregnancy (0.73°C) was associated with an odds ratio of 1.02 (95% confidence interval, 1.00–1.05) for small for gestational age and sex. Conclusion: Reduced fetal growth was associated with elevated ambient temperatures throughout and late in pregnancy, independently of air pollution and other risk factors. [ABSTRACT FROM AUTHOR]
