Are health behaviors associated with mental health among tertiary education students? A systematic review of cohort studies. JOURNAL OF AMERICAN COLLEGE HEALTH : J OF ACH 2023:1-13. [PMID: 37105759 DOI: 10.1080/07448481.2023.2201865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 03/19/2023] [Accepted: 04/05/2023] [Indexed: 06/19/2023]
Abstract
OBJECTIVE To evaluate the association between health behaviors with mental health among tertiary education students. METHODS Six databases were searched until September 2021 for prospective cohort studies evaluating the association between health behavior(s) (dietary intake, physical activity, sedentary behavior, alcohol intake, sleep, smoking or illicit drug use) and mental health. Two independent reviewers screened records for inclusion, extracted data and completed risk of bias assessments. RESULTS 33 studies were included (14 assessed sleep, 14 alcohol intake, 13 physical activity, 8 smoking, 6 sedentary behavior, 4 diet, 1 illicit drug use). A consistent association between poor sleep, and physical inactivity with increased risk of poor psychological wellbeing, and between poor sleep and increased mental ill-health related outcomes was demonstrated. CONCLUSION Findings suggest interventions to address poor sleep and physical inactivity among students may positively impact mental health. Further research of other health behaviors, and their association with mental health, is required.

Changes in physical activity, diet, sleep, and mental well-being when starting university: A qualitative exploration of Australian student experiences. JOURNAL OF AMERICAN COLLEGE HEALTH : J OF ACH 2023:1-10. [PMID: 37014766 DOI: 10.1080/07448481.2023.2194426] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 11/20/2022] [Accepted: 03/14/2023] [Indexed: 06/19/2023]
Abstract
Objective: To explore young adult's experiences of how starting university influenced their physical activity, diet, sleep, and mental well-being, and barriers and enablers to health behavior change. Participants: University students aged 18-25 years. Methods: Three focus groups were conducted in November 2019. Inductive thematic approach was utilized to identify themes. Results: Students (female: n = 13, male: n = 2, other gender identity: n = 1, 21.2 (1.6) years) reported mental well-being, physical activity levels, diet quality and sleep health were negatively affected. Stress, study demands, university timetabling, not prioritizing physical activity, cost and availability of healthy foods, and difficulty falling asleep were key barriers. Health behavior change interventions aiming to support mental well-being need to include both information and support features. Conclusions: There is a significant opportunity to improve the transition to university for young adults. Findings highlight areas to target in future interventions to improve physical activity, diet, and sleep of university students.

Characterizing occupational radon exposure greater than 100 Bq/m 3 in a highly exposed country. Sci Rep 2022; 12:21323. [PMID: 36494406 PMCID: PMC9734100 DOI: 10.1038/s41598-022-25547-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 11/30/2022] [Indexed: 12/13/2022] Open
Abstract
Radon is an established lung carcinogen concentrating in indoor environments with importance for many workers worldwide. However, a systematic assessment of radon levels faced by all workers, not just those with direct uranium or radon exposure, has not previously been completed. The objective of this study was to estimate the prevalence of workers exposed to radon, and the level of exposure (> 100-200 Bq/m3, 200-400 Bq/m3, 400-800 Bq/m3, and > 800 Bq/m3) in a highly exposed country (Canada). Exposures among underground workers were assessed using the CAREX Canada approach. Radon concentrations in indoor workplaces, obtained from two Canadian surveys, were modelled using lognormal distributions. Distributions were then applied to the susceptible indoor worker population to yield the number of exposed workers, by occupation, industry, province, and sex. In total, an estimated 603,000 out of Canada's 18,268,120 workers are exposed to radon in Canada. An estimated52% of exposed workers are women, even though they comprise only 48% of the labour force. The majority (68%) are exposed at a level of > 100-200 Bq/m3. Workers are primarily exposed in educational services, professional, scientific and technical services, and health care and social assistance, but workers in mining, quarrying, and oil and gas extraction have the largest number of exposed workers at high levels (> 800 Bq/m3). Overall, a significant number of workers are exposed to radon, many of whom are not adequately protected by existing guidelines. Radon surveys across multiple industries and occupations are needed to better characterize occupational exposure. These results can be used to identify exposed workers, and to support lung cancer prevention programs within these groups.

Health behavior interventions for university students measuring mental health outcomes: A scoping review. Front Public Health 2022; 10:1063429. [PMID: 36568797 PMCID: PMC9771454 DOI: 10.3389/fpubh.2022.1063429] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Accepted: 11/04/2022] [Indexed: 12/12/2022] Open
Abstract
Introduction Many university students have poor mental health, and co-occurring health risk behaviors. Targeting health behavior change in this population may improve mental health outcomes. This scoping review describes the extent and range of randomized controlled trials (RCT) evaluating interventions targeting health risk behaviors and measuring a mental health outcome, among university students. Methods Six electronic databases were searched for RCTs published until the 18th May 2021. Eligible RCTs included university students, evaluated interventions that promoted health behavior change (i.e., dietary intake, physical activity, sedentary behavior, alcohol and drug use, smoking, and sleep), and measured a mental health-related outcome. Results Fifty-nine RCTs met the inclusion criteria that were published from 2000 to 2021, and over half (n = 33) were conducted in the United States. Interventions evaluated within the RCTs (n = 92) predominantly targeted changes to dietary intake (n = 41 interventions), physical activity (n = 39), or alcohol intake (n = 35). Most interventions targeted one (n = 51) or two (n = 27) health behaviors only. Included RCTs considered mental ill health outcomes (n = 24), psychological wellbeing outcomes (n = 20), or both (n = 15). Discussion This scoping review identified a moderate volume of experimental research investigating the impact of health behavior interventions on university students' mental health. There is scope for further research examining health behavior interventions targeting university students, particularly interventions taking a multi-behavioral approach.

Gender differences in social desirability and approval biases, and associations with diet quality in young adults. Appetite 2022; 175:106035. [PMID: 35405222 DOI: 10.1016/j.appet.2022.106035] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 03/29/2022] [Accepted: 04/01/2022] [Indexed: 01/05/2023]
Abstract
Social desirability and approval biases can influence self-report of diet, contributing to inaccurate assessment. Biases may be influenced by sex. This study examined gender differences in social desirability and approval, and diet quality in young adults, and relationships between social biases and diet quality. Data from 1003 young adults participating in the Advice, Ideas and Motivation for My Eating trial, median age 21.7 years, BMI 24.7 kg/m2 were included. Biases were measured using Marlowe-Crowne Social Desirability Scale Short-Form, Martin Larsen Approval Motivation Scale, and diet quality using the Australian Recommended Food Score. Pearson chi-square, t-test and Wilcoxon tests evaluated gender differences and Spearman's rank-order tested strengths of correlations between biases and diet quality. Social desirability did not differ by gender, however females reported higher social approval scores than males (p = 0.009). Among females, there was a positive correlation between social desirability and diet quality (p = 0.002), and between social approval and dairy sub-scale (p < 0.001); and a negative correlation between social approval and vegetable subscale (p = 0.045). Among males there were no correlations between social desirability or social approval and overall diet quality. Social approval may be more common in females and influence self-reported diet. To address bias and mis-reporting errors, future studies should account for participants' social desirability and/or social approval status, especially among young adult females. Further research is needed to explore gender differences in social desirability and approval in young adults, and associations between social biases and diet quality.

Efficacy of a Multi-Component m-Health Diet, Physical Activity, and Sleep Intervention on Dietary Intake in Adults with Overweight and Obesity: A Randomised Controlled Trial. Nutrients 2021; 13:nu13072468. [PMID: 34371975 PMCID: PMC8308779 DOI: 10.3390/nu13072468] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 07/16/2021] [Accepted: 07/17/2021] [Indexed: 12/14/2022] Open
Abstract
This three-arm randomised controlled trial evaluated whether (1) a multi-component weight loss intervention targeting diet, physical activity (PA), and sleep was effective at improving dietary intake over six months and 12 months, compared with a control, and (2) the enhanced diet, PA, and sleep intervention was more effective at improving dietary intake than the traditional diet and PA intervention. A total of 116 adults (70% female, 44.5 years, BMI 31.7 kg/m2) were randomised to either traditional diet and PA intervention; enhanced diet, PA, and sleep intervention; or wait-list control. To examine between-group differences, intervention groups were pooled and compared with the control. Then, the two intervention groups were compared. At six months, the pooled intervention group consumed 1011 fewer kilojoules/day (95% CI −1922, −101), less sodium (−313.2 mg/day; 95% CI −591.3, −35.0), and higher %EI from fruit (+2.1%EI; 95% CI 0.1, 4.1) than the controls. There were no differences in intake between the enhanced and traditional groups at six months. At 12 months, the pooled intervention and control groups reported no significant differences. However, compared to the traditional group, the enhanced reported higher %EI from nutrient-dense foods (+7.4%EI; 95% CI 1.3, 13.5) and protein (+2.4%EI; 95% CI 0.1, 4.6), and reduced %EI from fried/takeaway foods (−3.6%EI; 95% CI −6.5, −0.7), baked sweet products (−2.0%EI; 95% CI −3.6, −0.4), and packaged snacks (−1.1%EI; 95% CI −2.2, −0.3). This weight loss intervention reduced total energy and sodium intakes as well as increased fruit intake in adults at six months. The enhanced intervention group reported improved dietary intake relative to the traditional group at 12 months.

Behavioural mediators of reduced energy intake in a physical activity, diet, and sleep behaviour weight loss intervention in adults. Appetite 2021; 165:105273. [PMID: 33945842 DOI: 10.1016/j.appet.2021.105273] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 03/29/2021] [Accepted: 04/16/2021] [Indexed: 10/21/2022]
Abstract
Reduced energy intake is a major driver of weight loss and evidence suggests that physical activity, dietary, and sleep behaviours interact to influence energy intake. Energy restriction can be challenging to sustain. Therefore to improve intervention efficacy, evaluation of how changes in physical activity, diet, and sleep behaviours mediate reduced energy intake in adults with overweight/obesity who participated in a six-month multiple-behaviour-change weight loss intervention was undertaken. This was a secondary analysis of a 3-arm randomised controlled trial. Adults with body mass index (BMI) 25-40 kg/m2 were randomised to either: a physical activity and diet intervention; physical activity, diet, and sleep intervention; or wait-list control. Physical activity, dietary intake, and sleep was measured at baseline and six-months using validated measures. The two intervention groups were pooled and compared to the control. Structural equation modelling was used to estimate the mediated effects (AB Coefficient) of the intervention on total energy intake. One hundred and sixteen adults (70% female, 44.5y, BMI 31.7 kg/m2) were enrolled and 70% (n = 81) completed the six-month assessment. The significant intervention effect on energy intake at six-months (-1011 kJ/day, 95% CI -1922, -101) was partially mediated by reduced fat intake (AB = -761.12, 95% CI -1564.25, -53.74) and reduced consumption of energy-dense, nutrient-poor foods (AB = -576.19, 95% CI -1189.23, -97.26). In this study, reducing fat intake and consumption of energy-dense, nutrient-poor foods was an effective strategy for reducing daily energy intake in adults with overweight/obesity at six-months. These strategies should be explicitly targeted in future weight loss interventions.

Abstract
OBJECTIVE The prospective relationships between poor sleep health, poor diet quality, and physical inactivity with self-rated health (SRH) are not well described. The aim of this study was to assess individual and joint associations between high-risk health behaviors and incident poor SRH. METHOD Participants from the Household Income and Labor Dynamics in Australia longitudinal cohort reporting "good" SRH in 2013 were included (n = 8,853) in 2020 data analysis. Logistic regression was used to assess odds of poor SRH in 2017 associated with (a) individual, (b) count, and (c) unique combinations of high-risk behaviors reported in 2013. RESULTS In the sample (48% female, Mage = 45.2 years, SD = 16.8), poor sleep health (OR = 1.66, 95% CI [1.38, 2.01]), physical inactivity (OR = 1.18, [1.01, 1.38]), and poor diet quality (OR = 1.38, [1.16, 1.65]) were associated with increased odds of poor SRH. Reporting one (OR = 1.76, [1.27, 2.43]), two (OR = 2.16, [1.57, 2.98]), and three (OR = 2.99, [2.02, 4.41]) high-risk behaviors was associated with increased odds of poor SRH. All unique combinations of high-risk behaviors were significantly associated with greater odds of poor SRH, except "poor sleep health only" (prevalence = 1.3%). Odds of poor SRH associated with high-risk behavior combinations ranged from 1.73 (95% CI [1.21, 2.47]) for "physical inactivity only" to 4.11 ([2.66, 6.35]) for "poor sleep health + poor diet quality." CONCLUSIONS Reporting ≥ 1 high-risk behavior was associated with increased odds of poor SRH. The combination of poor sleep health with poor diet quality was associated with the greatest odds of poor SRH. Improving multiple high-risk behaviors in combination may be more effective in preventing decline in SRH than improving any behavior alone.

The influence of sleep health on dietary intake: a systematic review and meta-analysis of intervention studies. J Hum Nutr Diet 2020; 34:273-285. [PMID: 33001515 DOI: 10.1111/jhn.12813] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 07/28/2020] [Accepted: 08/22/2020] [Indexed: 01/07/2023]
Abstract
BACKGROUND Poor dietary intake increases disease risk, and poor sleep influences diet. This systematic review and meta-analysis of intervention studies aimed to evaluate the effect of sleep health on dietary intake in adults. METHODS Five online databases were used to identify studies published between 1970 and 2019. Included studies were interventions that modified sleep and reported dietary outcomes. RESULTS Fifty four full texts were assessed and 24 publications were included. Following risk of bias appraisal, data were narratively summarised and a sub-group of studies (n = 15) was meta-analysed to determine the effect of sleep on dietary intake. One intervention modified sleep timing and 23 modified duration. Sleep duration was partially restricted (≤5.5 h night-1 ) (n = 16), totally restricted (n = 4), partially and totally restricted (n = 1), and extended (n = 2). Dietary outcomes were energy intake (n = 24), carbohydrate, fat, protein intake (n = 20), single nutrient intake (n = 5), diet quality (n = 1) and food types (n = 1). Meta-analysis indicated partial sleep restriction results in higher energy intake in intervention compared with control [standardised mean difference (SMD) = 0.37; 95% confidence interval (CI) = 0.21-0.52; P < 0.001], with a mean difference of 204 kcal (95% CI = 112-295; P < 0.001) in daily energy intake, and a higher percentage of energy from fat, protein, carbohydrate (fat: SMD = 0.33; 95% CI = 0.16-0.51; P < 0.001; protein: SMD = 0.30, 95% CI = 0.12-0.47, P = 0.001; carbohydrate: SMD = 0.22, 95% CI = 0.04-0.39, P = 0.014). CONCLUSIONS Partial sleep restriction with duration of ≤5.5 h day-1 increases daily energy intake, as well as fat, protein and carbohydrate intake. Further research is needed to determine the relationship between other dimensions of sleep health and dietary intake.

Efficacy of a Multi-component m-Health Weight-loss Intervention in Overweight and Obese Adults: A Randomised Controlled Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E6200. [PMID: 32859100 PMCID: PMC7503928 DOI: 10.3390/ijerph17176200] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 08/14/2020] [Accepted: 08/17/2020] [Indexed: 12/27/2022]
Abstract
BACKGROUND This study compared the efficacy of two multi-component m-health interventions with a wait-list control group on body weight (primary outcome), and secondary outcomes of cardiovascular risk factors, lifestyle behaviours, and mental health. METHODS Three-arm randomised controlled trial (Enhanced: physical activity, diet, sleep, Traditional: physical activity, diet, Control) with assessments conducted at baseline, 6 and 12 months. Participants (n = 116) were overweight or obese adults aged 19-65 (M = 44.5 [SD = 10.5]). The 6-month intervention was delivered via a smartphone app providing educational materials, goal-setting, self-monitoring and feedback, and also included one face-to-face dietary consultation, a Fitbit and scales. The trial was prospectively registered and conducted between May 2017 and September 2018. Group differences on primary and secondary outcomes were examined between the Pooled Intervention groups (Pooled Intervention = Enhanced and Traditional) and Control groups, and then between Enhanced and Traditional groups. RESULTS Nineteen participants (16.4%) formally withdrew from the trial. Compared with the Control group, average body weight of the Pooled Intervention group did not differ at 6 (between-group difference = -0.92, (95% CI -3.33, 1.48)) or 12 months (0.00, (95% CI -2.62, 2.62)). Compared with the Control group, the Pooled Intervention group significantly increased resistance training (OR = 7.83, (95% CI 1.08, 56.63)) and reduced energy intake at 6 months (-1037.03, (-2028.84, -45.22)), and improved insomnia symptoms at 12 months (-2.59, (-4.79, -0.39)). Compared with the Traditional group, the Enhanced group had increased waist circumferences (2.69, (0.20, 5.18)) and sedentary time at 6 months (105.66, (30.83, 180.48)), and improved bed time variability at 12 months (-1.08, (-1.86, -0.29)). No other significant differences were observed between groups. CONCLUSIONS Relative to Controls, the Pooled Intervention groups did not differ on body weight but improved resistance training, and reduced energy intake and insomnia symptom severity. No additional weight loss was apparent when targeting improvements in physical activity, diet and sleep in combination compared with physical activity and diet.

Abstract
BACKGROUND Recent research has demonstrated an association between dietary intake and sleep health that can influence chronic disease risk factors. A scoping review of research studies investigating dietary intake and sleep was undertaken to determine the extent and scope of research in laboratory-based, free-living and mixed settings. Additionally, this review determines how well subpopulations and geographical locations are represented and the methodologies used to assess outcome measures. METHODS Five online databases were used to identify papers published between 1970 and 2017. Included studies were those conducted in adults and reported both outcomes of interest: (i) sleep health, including sleep restriction and sleep hygiene and (ii) dietary outcomes, including altered nutrients, dietary patterns and supplements. RESULTS In total, 129 publications were included with the majority being dietary interventions investigating sleep outcomes (n = 109) with fewer being sleep interventions investigating and reporting dietary outcomes (n = 20). Dietary interventions were most often carried out in free-living environments, in contrast to sleep interventions that were most often carried out in laboratory-based environments. The majority of dietary interventions investigated use of a supplement (n = 66 studies), which was predominantly caffeine (n = 49). Sleep interventions investigated sleep duration only, with the majority (n = 17) investigating the effect of partial sleep restriction under 5.5 h per night on dietary intake, while three studies investigating total sleep deprivation. CONCLUSIONS Investigating broader aspects of dietary such as overall diet quality and dietary patterns and other components of sleep health such as quality, timing and sleep hygiene are important aspects for future research.

Abstract
INTRODUCTION Traditional behavioural weight loss trials targeting improvements in physical activity and diet are modestly effective. It has been suggested that sleep may have a role in weight loss and maintenance. Improving sleep health in combination with physical activity and dietary behaviours may be one strategy to enhance traditional behavioural weight loss trials. Yet the efficacy of a weight loss intervention concurrently targeting improvements in physical activity, dietary and sleep behaviours remains to be tested. METHODS AND ANALYSIS The primary aim of this three-arm randomised controlled trial is to examine the efficacy of a multicomponent m-Health behaviour change weight loss intervention relative to a waitlist control group. The secondary aims are to compare the relative efficacy of a physical activity, dietary behaviour and sleep intervention (enhanced intervention), compared with a physical activity and dietary behaviour only intervention (traditional intervention), on the primary outcome of weight loss and secondary outcomes of waist circumference, glycated haemoglobin, physical activity, diet quality and intake, sleep health, eating behaviours, depression, anxiety and stress and quality of life. Assessments will be conducted at baseline, 6 months (primary endpoint) and 12 months (follow-up). The multicomponent m-Health intervention will be delivered using a smartphone/tablet 'app', supplemented with email and SMS and individualised in-person dietary counselling. Participants will receive a Fitbit, body weight scales to facilitate self-monitoring, and use the app to access educational material, set goals, self-monitor and receive feedback about behaviours. Generalised linear models using an analysis of covariance (baseline adjusted) approach will be used to identify between-group differences in primary and secondary outcomes, following an intention-to-treat principle. ETHICS AND DISSEMINATION The Human Research Ethics Committee of The University of Newcastle Australia provided approval: H-2017-0039. Findings will be disseminated via publication in peer-reviewed journals, conference presentations, community presentations and student theses.

Balanced: a randomised trial examining the efficacy of two self-monitoring methods for an app-based multi-behaviour intervention to improve physical activity, sitting and sleep in adults. BMC Public Health 2016; 16:670. [PMID: 27473327 PMCID: PMC4967346 DOI: 10.1186/s12889-016-3256-x] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Accepted: 07/01/2016] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Many adults are insufficiently physically active, have prolonged sedentary behaviour and report poor sleep. These behaviours can be improved by interventions that include education, goal setting, self-monitoring, and feedback strategies. Few interventions have explicitly targeted these behaviours simultaneously or examined the relative efficacy of different self-monitoring methods. METHODS/DESIGN This study aims to compare the efficacy of two self-monitoring methods in an app-based multi-behaviour intervention to improve objectively measured physical activity, sedentary, and sleep behaviours, in a 9 week 2-arm randomised trial. Participants will be adults (n = 64) who report being physically inactive, sitting >8 h/day and frequent insufficient sleep (≥14 days out of last 30). The "Balanced" intervention is delivered via a smartphone 'app', and includes education materials (guidelines, strategies to promote change in behaviour), goal setting, self-monitoring and feedback support. Participants will be randomly allocated to either a device-entered or user-entered self-monitoring method. The device-entered group will be provided with a activity tracker to self-monitor behaviours. The user-entered group will recall and manually record behaviours. Assessments will be conducted at 0, 3, 6, and 9 weeks. Physical activity, sedentary behaviour and sleep-wake behaviours will be measured using the wrist worn Geneactiv accelerometer. Linear mixed models will be used to examine differences between groups and over time using an alpha of 0.01. DISCUSSION This study will evaluate an app-based multi-behavioural intervention to improve physical activity, sedentary behaviour and sleep; and the relative efficacy of two different approaches to self-monitoring these behaviours. Outcomes will provide information to inform future interventions and self-monitoring targeting these behaviours.

Abstract
Years ago we undertook to define Health Informatics (HI) competencies. This effort resulted in the creation of a document that articulated HI roles, the challenges faced by HI professionals, the high-level tasks that they needed to undertake to address these challenges and the competencies (skills, knowledge, and experience) they needed to complete these tasks. Unfortunately, in so doing we created what is arguably the most boring book in history, shoes contents are very difficult to extract, use, maintain and improve. We report here the completion of a pilot of a system that we believe corrects this situation. It is a webbased tool that incorporates all of the material, from roles to detailed competencies, enabling them to be accessed and used for a variety of purposes, the most notable of which is professional self-assessment.

Abstract
High Body Mass Index (BMI) has been associated with improved survival of End-Stage Renal Disease (ESRD) patients on chronic hemodialysis (HD); however, studies on the relationship of BMI with survival in Peritoneal Dialysis (PD) patients have yielded conflicting results. The purpose of this study was to evaluate the impact of BMI on survival of Canadian ESRD patients on PD, correcting for their age, sex, race, diabetes mellitus, and arterial hypertension. In an intent to treat study, we reviewed data of the Canadian Organ Replacement Register (CORR), of incident patients, starting PD between 1994 and 1998 and followed up from their initial PD treatment to the end of 2003. Patients were censored at loss to follow up, transplantation, and the end of the observation period. Cox regression (multivariate) analysis was performed and adjustments were made for age, gender, race, primary renal disease and BMI. During these years, 4054 patients commenced PD, 1742 (43%) of them were females and 1471 (36.3%) were diabetics. The majority were Caucasians (n=3058, 75.4%); 120 (3%) belonged to the First Nations, 137 (3.4%) were black, and the rest (739 pts-18.2%) belonged to various other ethnicities. Based on quartiles of the BMI distribution, 1130 patients (28%) had a BMI < 18.5 kg/m(2); 1163 (28.7%), 18.5-24.9 kg/m(2); 1214 (30%), 25-29.9 kg/m(2); 547 (13.5%) > 30 kg/m(2). Intent to treat Cox regression analysis showed that being underweight was a strong risk factor for death. Specifically, a BMI less than 18.5 was associated with a death hazard ratio (HR) 1.3, (CI: 1.1-1.6). On the contrary, BMI > 30 was not associated with worse survival than those with normal BMI (HR = 1.009, CI = 0.89-1.14). High-BMI patients should not be discouraged from PD just because of their size.

Abstract
We describe a web-based system that enables an individual to assess him/her self against the set of competencies required for a variety of roles in the area of Applied Health Informatics (AHI). The competencies themselves were developed by a multi-disciplinary team under the auspices of the Canadian Institute for Health Research (CIHR), and include the knowledge, skills, and experience necessary to fulfill specific roles as an applied health informatician. Both textual and graphical information is presented to the user and potential mechanisms for correcting competency gaps are presented in this online interactive system.

Abstract
AIM The purpose of this study was to test the reliability of an exophthalmometer commonly used in the Netherlands; to determine the exophthalmometry value distribution with this instrument and to assess the upper exophthalmometry limits of normal in a healthy, adult, Caucasian, Dutch population. Furthermore, to assess the effects of gender and age on exophthalmometry readings in this group and in a group of Graves' patients by comparing healthy, adult, Caucasian, Dutch individuals with adult, Caucasian, Dutch Graves' patients. METHODS To test the reliability of our Hertel exophthalmometer, we determined the interobserver variation between two observers by measuring 160 eyes in healthy, adult, Caucasian, Dutch females and males (10 females and 10 males in each decade between 20 and 60 years of age). These data were also used for the assessment of the Hertel value distribution and for defining the upper limits of normal in these individuals by logistic regression analysis. The effects of disease, age and gender were established using these data plus data of a retrospective study of 393 adult, Caucasian, Dutch females (n=294) and males (n=99) with Graves' orbitopathy in whom Hertel values were measured with the same exophthalmometer. RESULTS Exophthalmometry using an Hertel exophthalmometer appeared reliable (Pearson correlation coefficient for interobserver variation 0.89; 96% of the Hertel values measured by two observers were within the limits (of 2 mm) of agreement). Hertel values usually show a normal distribution in healthy individuals and in Graves' patients and are sex- and age-dependent, but there was no dependence on age in this small series in adults. Logistic regression analysis revealed an upper limit of normal of 16 mm in females and 20 mm in males in our group, using the exophthalmometer described. CONCLUSIONS Exophthalmometry is reliable and absolute measurement of proptosis is feasible. International standardization of Hertel exophthalmometry is required in order to compare exophthalmometry data in the literature reliably.

Abstract
BACKGROUND Breast carcinoma metastasises to the eye more frequently than is clinically recognised. The incidence is perhaps not appreciated, either because of the more common involvement and consequences of spread to major organs (such as lung, liver, or bone) or because a number of eye lesions are small and asymptomatic. Over a 6-month period, all patients with locally advanced or metastatic breast cancer were screened for ocular involvement and as a result management recommendations made. MATERIALS AND METHODS Between January 2001 and June 2001, 68 patients with known locally advanced or metastatic breast carcinoma were referred for a screening ophthalmic examination. The aim of the study was to assess the frequency of asymptomatic ocular metastases by breast carcinoma in visually asymptomatic patients. The recognition and early treatment of both ocular metastases and ocular manifestations of metastatic breast carcinoma are important in maximising the quality of life in this group of palliative patients. These patients were all referred and recruited from the Beatson Oncology Centre and Breast Unit at the Western Infirmary, Glasgow by the oncologist (ANH). Examination included visual acuity assessment, slit-lamp examination, tonometry, and indirect ophthalmoscopy. RESULTS The median time from diagnosis of breast carcinoma to ophthalmic screening was 5 years (range 6 months-23 years). No patient had any evidence of choroidal metastases on ophthalmic examination. Four patients (5.8%) had ophthalmic manifestations of metastatic breast carcinoma and a further two had ocular complications of treatment. One patient had a restrictive motility problem from a metastatic deposit to her lateral rectus muscle and another had corneal punctate epitheliopathy secondary to a seventh nerve palsy. A further patient had coarse nystagmus from cerebellar metastases and the final patient of the four had a Horner's syndrome from metastases in the neck. In addition, two patients had symptomatic dry eyes whose onset coincided with commencement of chemotherapy. CONCLUSION Ophthalmic manifestations of metastatic breast carcinoma occurred in 5.8% of asymptomatic patients. Orbital metastases were documented in one patient. No case of choroidal metastases was observed in this group with advanced or metastatic disease. Therefore, patients do not need to be routinely screened particularly for choroidal metastases.

Abstract
AIM To review the outcome of upper lid lowering for eyelid retraction at a single unit over five years and to report the high complication rate with mersilene mesh as a spacer material. METHODS We retrospectively reviewed the case records of 48 patients who underwent upper lid lowering for lid retraction between January 1995 and January 2000. RESULTS The indication for surgery was eyelid retraction secondary to dysthyroid disease in 41 patients, seventh nerve palsy in 3 cases, overcorrection of ptosis elsewhere in 3 cases and previously treated orbital lymphoma in one patient. A good result was achieved in 80% with a single procedure. Undercorrection occurred in 10% and overcorrection occurred in 8%. Spacer material, either mersilene mesh or more recently vicryl, was used in 42% of lids. Late extrusion of mersilene mesh occurred in 20% of lids that had a spacer inserted an average of 18 months postoperatively. CONCLUSIONS The high extrusion rate with mersilene was unacceptable and the alternative spacer material vicryl is now used. The possibility of revisional surgery because of under- or overcorrection should be explained to patients.

Abstract
A 21-year-old man presented with severe corneal cystinosis and steroid-related cataract bilaterally. Rather than combined cataract surgery and penetrating keratoplasty, the patient had uneventful phacoemulsification and intraocular lens implantation after which visual acuity improved to 66 in both eyes. The outcome indicates that conventional phacoemulsification is sufficient in these cases. A guarded prognosis is advised in patients with cystinosis having cataract surgery as the fundal view is often impaired and there may be associated maculopathy.

Abstract
PURPOSE To document the visual outcome and postoperative complications in infants who had congenital cataract surgery with posterior chamber intraocular lens (PC IOL) implantation in the first year of life. SETTING The Children's Hospital, Dublin, Ireland. METHODS Twenty-seven eyes of 20 infants were reviewed. Seven infants (14 eyes) had bilateral congenital cataract and 13 (13 eyes), uniocular cataract. The mean age at surgery was 4 months (range 3 weeks to 11 months). A standard surgical technique involved anterior capsulorhexis, phacoemulsification with or without posterior capsulorhexis with in-the-bag PC IOL implantation, and no anterior vitrectomy. Surgery was performed by 1 surgeon. The mean follow-up was 41 months (range 6 to 88 months). RESULTS The main complication was lens reproliferation into the visual axis. Of the 11 eyes that did not have a primary posterior capsulorhexis, 10 had 1 or more capsulotomies. Seven required a neodymium:YAG (Nd:YAG) laser capsulotomy a mean of 6 months postoperatively, and 2 had 2 Nd:YAG capsulotomies. Six eyes also had a surgical capsulotomy when the membrane was deemed too thick for further laser treatment. Fourteen of 25 eyes had a primary posterior capsulorhexis; 8 had no further intervention. Four eyes had persistent hyperplastic primary vitreous (PHPV), 3 required a surgical capsulotomy, 2 had an Nd:YAG laser capsulotomy, 2 had an anterior vitrectomy, and 1 developed open-angle glaucoma. There was a mean refractive shift of 6.0 diopters after a mean follow-up of 41 months, with most of the myopic shift occurring in the first 24 months. CONCLUSIONS Visual axis reopacification was the main complication of IOL implantation in infants, with PHPV leading to more complications and repeat procedures. Anterior vitrectomy appeared to reduce the reoperation rate. Results indicate that primary posterior capsulorhexis is important and Nd:YAG capsulotomy is not satisfactory in infants. In addition, the reduction in glaucoma with IOL implantation, if borne out over the long term, is a significant advantage in cases of congenital cataract.

Abstract
The objective was to study the patterns of emergency department visits and to make recommendations on ways of improving the service. Patients' demographic data, diagnoses, source of referral and follow-up were entered onto a database. Three thousand seven hundred consecutive patients' visits over a six-week period were entered. The average daily attendance ranged between 80-100 people. 54% of patients were self-referrals. 20% had a previous visit to the hospital. 17% were referred from a GP, 5% from another hospital and 3% from opticians. Superficial injury to the eye and ocular adnexae was the most common diagnostic category. 56% of patients were discharged at the first visit. 23% returned for review to casualty. 14% were referred to OPD, 3% directly to a consultant for review and 1% were admitted to hospital. Waiting times for consultation for patients was highly variable ranging from thirty minutes to five hours, mean two hours. The department provides a service far in excess of its defined function. Non urgent problems accounted for as much as 60-70% of all emergency department visits. Improvement of ophthalmic training of GPs, introduction of an ophthalmic triage system and expansion of outpatient services is recommended so that casualty remains a genuine emergency service and not a primary care service with uncontrollable numbers and unacceptable waiting times for patients.

Abstract
HYPOTHESIS Angioaccess procedures for dialysis have varied patency rates with frequent need for intervention. A superficialized arteriovenous brachiobasilic fistula created as a 2-step procedure will have good long-term patency with minimal complication. DESIGN Retrospective medical record review and patient interview. SETTING Tertiary referral university hospital. PATIENTS Twelve patients who underwent delayed superficialization of brachiobasilic fistula from September 1994 to April 2000. MAIN OUTCOME MEASURES Patency of fistula for dialysis, and major and minor complications, including revisions. RESULTS Delayed superficialization of brachiobasilic fistula was performed in 12 patients. Fistulas have been used for a mean duration of 22.4 months (range, 10-59 months). Two patients required alternate access owing to thrombosis of brachiobasilic fistula. CONCLUSIONS The delayed superficialized brachiobasilic arteriovenous fistula has a good initial patency rate with minimal complications. It should be considered early in patients if radiocephalic fistula is unavailable.

Abstract
PURPOSE To determine the efficacy of dacryocystoplasty with balloon dilation in the treatment of acquired obstruction of the nasolacrimal system in adults. METHODS Balloon dacryocystoplasty was performed in 52 eyes of 42 patients under general anaesthetic. A Teflon-coated guidewire was introduced through the canaliculus and manipulated through the nasolacrimal system and out of the nasal aperture. A 4 mm wide 3 cm coronary angioplasty balloon catheter was threaded over the guidewire in a retrograde fashion and dilated at the site of obstruction. RESULTS There was complete obstruction in 30% of cases and partial obstruction in 70%. The most common site of obstruction was the nasolacrimal duct. The procedure was technically successful in 94% of cases. The overall re-obstruction rate was 29% within 1 year of the procedure. There was an anatomical failure rate of 17% for partial obstruction and 69% for complete obstruction within 1 year. CONCLUSIONS Balloon dacryocystoplasty has a high recurrence rate. There may be a limited role for this procedure in partial obstructions. Further refinements of the procedure are necessary before it can be offered as a comparable alternative to a standard surgical dacryocystorhinostomy.

Abstract
Two cases of ischaemic optic neuropathy, which occurred as a complication of oncological neck surgery, are reported. These cases are submitted because of the apparent scarcity in the literature of this complication after head and neck surgery. They are also unusual because they presented with different clinical manifestations of ischaemic optic neuropathy after separate forms of bilateral neck dissection. A literature review identifies a small number of similar cases and risk factors and preventative measures are discussed.

Abstract
1. The 5-year actuarial graft, patient and functional graft survival rates were analyzed in 743 consecutive primary cadaveric kidney transplants from The Toronto Hospital between January 1985-December 1997. 2. Recipient age > or = 55 years, male recipient sex, recipient diabetes mellitus, CIT > 36 hours and delayed graft function were found to significantly decrease patient survival. 3. Recipient age > or = 55 years, sensitization to HLA antigens (peak PRA > 50%), donor/recipient HLA antigen mismatches, CIT > 36 hours, delayed graft, function and 6-month SCr > 200 mumol/L were found to significantly decrease graft survival. 4. Acute rejection episodes had no significant impact on overall 5-year patient or graft survival. 5. The observation that serum creatinine > 200 mumol/L had a major adverse influence on long-term outcome reflects the importance of functional renal mass on graft survival.
