ABSTRACT

OBJECTIVE: To determine the combined longitudinal effect of body mass index (BMI) and physical activity (PA) on health-related quality of life (HrQoL), using the SF-6D (SF-36) utility measure. METHODS: Five waves of self-reported data from the 1946-51 cohort (n=5,200; data collection, 2001-2013) of the Australian Longitudinal Study on Women's Health were used. Mixed effect models were employed to address the objective. RESULTS: Women with high PA experienced higher HrQoL regardless of BMI group, however, for those healthy or overweight, there was a very small decline in HrQoL over time. Women reporting no PA levels experienced the lowest baseline mean SF-6D score within each BMI group, with decreasing trajectories over the follow-up period. The rate of decline was greatest in women with obesity. Within each BMI group, there was a large, increasing gap in HrQoL between those who reported no and low PA over time. Women with obesity and high PA experienced similar HrQoL trajectories to women with normal weight or overweight with low PA levels. Overweight women with moderate PA experienced similar HrQoL to those with low PA but normal weight. CONCLUSIONS: PA may mitigate the adverse effect of overweight and obesity on HrQoL at mid-life, at higher activity levels. Implications for public health: PA benefits HrQoL regardless of body mass, with larger gains for those currently not physically active. Moderate to high PA may mitigate the effect of overweight and obesity.

ABSTRACT

There is substantial multimorbidity at mid-life but little is known about the strength of evidence on multimorbidity and health-related quality of life (HrQoL) at mid-life. This review addresses this gap, focusing on studies of the general population. PubMed, Web of Science, Embase and APA PsycNET databases were screened on 6 March 2017 for original research on multimorbidity and HrQoL in adults aged 40-65 years from the general population. Studies focused on index conditions, using single-item HrQoL measures, unlikely to represent the general population (e.g. primary care), and papers that were not in the English language were excluded. A narrative synthesis was presented due to heterogeneity in the measurement of multimorbidity. Of the 2557 articles, 83 underwent full text screening and 8 were included in the review. Included studies were of moderate to high quality and no exclusions were made on the basis of quality or bias. Multimorbidity was associated with poorer HrQoL at mid-life. Two cross-sectional studies found that adults with multimorbidity at early mid-life reported poorer HrQoL than adults with multimorbidity at late mid-life, while another found the reverse. Two distinct disease clusters were identified: mental health conditions and cardiovascular disease (CVD). Those in the mental health cluster reported poorer HrQoL than those in the CVD cluster, women more so than men. Limitations of the selected studies include lack of longitudinal evidence, use of self-reported conditions and no assessment of disease severity. Multimorbidity is associated with poor HrQoL at mid-life at the population level, with some evidence of differences in association with age and disease cluster and sparse evidence on sex differences. Longitudinal research using a weighted disease severity index and multimorbidity trajectories is needed to strengthen the evidence base.

ABSTRACT

OBJECTIVE: To assess patterns and levels of dietary supplement use among Australian Defence Forces, previously deployed to the Middle East Area of Operations. DESIGN: A cross-sectional study. Participants of a large survey self-completed questions about dietary supplement use, health status, personal and job-related characteristics, and lifestyle factors. Frequency of current use of supplements was assessed in three categories (bodybuilding, energy and weight loss). SETTING: Middle East Area of Operations post-deployment health survey. SUBJECTS: Current and ex-serving Australian Defence Force personnel (n 14 032) who deployed to the Middle East between 2001 and 2009. RESULTS: Bodybuilding supplements were used by 17·5 % of participants, energy supplements by 24·5 % and weight-loss supplements by 7·6 %. Overall, 32·3 % of participants used any of these supplements. Bodybuilding and energy supplements were more often used by men, younger persons and those in the Army, while weight-loss supplements were more commonly used by women and Navy personnel. Supplements in all three categories were more commonly used by persons in lower ranks, active service and combat roles. Users of bodybuilding supplements had healthier lifestyles and better health status, while users of energy and weight-loss supplements had less healthy lifestyles and poorer mental and physical health status. Overall, 11·7 % of participants used supplements containing caffeine and 3·6 % used a creatine-containing product. CONCLUSIONS: Use of dietary supplements among Australian Defence Force personnel is common, and patterned by lifestyle factors and health status.

ABSTRACT

PURPOSE: To investigate how SF-6D utility scores change with age between generations of women and to quantify the relationship of SF-6D with lifestyle factors across life stages. METHODS: Up to seven waves of self-reported, longitudinal data were drawn for the 1973-1978 (young, N = 13772), 1946-1951 (mid-age, N = 12792), 1921-1926 (older, N = 9972) cohorts from the Australian Longitudinal Study on Women's Health. Mixed effects models were employed for analysis. RESULTS: Young and mid-age women had similar average SF-6D scores at baseline (0.63-0.64), which remained consistent over the 16-year period. However, older women had lower scores at baseline at 0.57 which steadily declined over 15 years. Across cohorts, low education attainment, greater difficulty in managing income, obesity, physical inactivity, heavy smoking, no alcohol consumption, and increasing stress levels were associated with lower SF-6D scores. The magnitude of effect varied between cohorts. SF-6D scores were lower amongst young women with high-risk drinking behaviours than low-risk drinkers. Mid-age women, who were underweight, never married, or underwent surgical menopause also reported lower SF-6D scores. Older women who lived in remote areas, who were ex-smokers, or were underweight, reported lower SF-6D scores. CONCLUSION: The SF-6D utility score is sensitive to differences in lifestyle factors across adult life stages. Gradual loss of physical functioning may explain the steady decline in health for older women. Key factors associated with SF-6D include physical activity, body mass index, menopause status, smoking, alcohol use, and stress. Factors associated with poorer SF-6D scores vary in type and magnitude at different life stages.

ABSTRACT

This study explored the impact of multiple deployments on the health and well-being of the partners (married or de facto) and children of Australian military personnel who have deployed frequently. Permission to contact military partners was sought from a sample of Australian Defence Force (ADF) members. Partners provided data on deployment history, physical health, mental health, and their children's emotions, and behaviors. Associations between multiple deployments and health and well-being of partners and children were assessed using logistic regression. Data were collected from 1,332 Australian Defence Force partners (response rate 36%) with 1,095 children aged between 4 and 17 years. Almost half (47%) of partners had experienced more than one deployment, mainly to Timor-Leste, Iraq, and Afghanistan. There was little evidence of associations between numbers of deployments and the health of the partner. In contrast, more behavioral problems were reported for children who experienced two or more deployments with odds ratios generally greater than 2 and significant trends with increasing numbers of deployment. Although military families who experience multiple deployments may, by selection, be more resilient than those who have fewer deployments, these results suggest that adverse impacts on the children may accrue with increasing parental absences because of deployment.

ABSTRACT

INTRODUCTION: Unit cohesion has been shown to bolster the mental health of military personnel; hence, it is important to identify the characteristics that are associated with low unit cohesion, so that interventions to improve unit cohesion can be targeted and implemented. Little is known about the factors associated with low unit cohesion. This research aims to identify demographic, military service and deployment factors associated with low unit cohesion. METHODS: Data from a self-reported cross-sectional study of 11 411 current or ex-serving Australian military personnel deployed to Iraq or Afghanistan between 2001 and 2009 were used. Multivariable logistic regression was used to investigate the research aims. RESULTS: Being female (adjusted OR (aOR) (95% CI) 1.35 (1.21 to 1.51)), non-commissioned officer (aOR (95% CI) 1.50 (1.39 to 1.62)), lower ranked (aOR (95% CI) 1.74 (1.51 to 2.01)) or having left military service (aOR (95% CI) 1.71 (1.46 to 2.02)) was associated with reporting low unit cohesion. Potentially modifiable factors such as performing logistic roles on deployment (aOR (95% CI) 1.13 (1.01 to 1.27)), dissatisfaction with work experience on deployment such as working with colleagues who did not do what was expected of them (aOR (95% CI) 4.09 (3.61 to 4.64)), and major problems at home while deployed (aOR (95% CI) 1.50 (1.38 to 1.63)) were also associated with reporting low unit cohesion. CONCLUSIONS: This is the first study to identify demographic, military service and deployment factors associated with low unit cohesion. The modifiable nature of unit cohesion means that military leaders could use this information to identify subgroups for targeted resilience interventions that may reduce vulnerabilities to mental health problems and improve the job satisfaction, preparedness and deployment experiences of serving members.

ABSTRACT

OBJECTIVE: To examine whether the relationship between traumatic exposure on deployment and poor mental health varies by the reported level of childhood adversity experienced in Australian military veterans deployed to the Bougainville or East Timor military operations. METHODS: Cross-sectional self-reported survey data were collected in 2008 from 3,564 Australian military veterans who deployed to East Timor or Bougainville on their deployment experiences, health and recall of childhood events. Multivariable logistic regression was used to investigate the association between childhood adversity, deployment exposures and mental health. RESULTS: The most common childhood adversity reported was 'not having a special teacher, youth worker or family friend who looked out for them while growing up'. On average, responders reported experiencing 3.5 adverse childhood experiences (SD 2.7) and averaged 5.3 (SD 4.9) traumatic exposures on deployment. Both childhood adversity and traumatic exposures on deployment were associated with higher odds of poorer mental health. However, there was no evidence that level of childhood adversity modified the association between traumatic exposure and mental health. CONCLUSIONS/IMPLICATIONS: These findings suggest that military personnel who recalled a higher level of childhood adversity may need to be monitored for poor mental health and, if required, provided with appropriate support.

ABSTRACT

INTRODUCTION: Stereoscopic vision is a critical part of the human visual system, conveying more information than two-dimensional, monoscopic observation alone. This study aimed to quantify the contribution of stereoscopy in assessment of radiographic data, using widely available three-dimensional (3D)-capable display monitors by assessing whether stereoscopic viewing improved the characterisation of cerebral aneurysms. METHODS: Nine radiology registrars were shown 40 different volume-rendered (VR) models of cerebral computed tomography angiograms (CTAs), each in both monoscopic and stereoscopic format and then asked to record aneurysm characteristics on short multiple-choice answer sheets. The monitor used was a current model commercially available 3D television. Responses were marked against a gold standard of assessments made by a consultant radiologist, using the original CT planar images on a diagnostic radiology computer workstation. RESULTS: The participants' results were fairly homogenous, with most showing no difference in diagnosis using stereoscopic VR models. One participant performed better on the monoscopic VR models. On average, monoscopic VRs achieved a slightly better diagnosis by 2.0%. CONCLUSIONS: Stereoscopy has a long history, but it has only recently become technically feasible for stored cross-sectional data to be adequately reformatted and displayed in this format. Scant literature exists to quantify the technology's possible contribution to medical imaging - this study attempts to build on this limited knowledge base and promote discussion within the field. Stereoscopic viewing of images should be further investigated and may well eventually find a permanent place in procedural and diagnostic medical imaging.
