Retrospective analysis of cancer survival across South-Western Victoria in Australia.

OBJECTIVE: This paper aims to describe cancer survival and examine association between survival and socio-demographic characteristics across Barwon South-Western region (BSWR) in Victoria, Australia. DESIGN: This study is based on the retrospective cohort database of patients accessing oncology services across BSWR. SETTING: Six rural and three urban hospital settings across the BSWR. PARTICIPANTS: The participants were patients who were diagnosed with cancer in 2009. MAIN OUTCOME MEASURES: Overall survival (OS) of participants was the main outcome measure. RESULTS: Total of 1778 eligible patients had four-year OS for all cancers combined of 59.7% (95% CI, 57.4-62.0). Improved OS was observed for patients in the upper socio-economic tertile (64.2%; 95% CI, 60.9-67.5) compared to the middle (59.3%; 95% CI, 55.5-63.1) and lowest tertiles (49.6%; 95% CI, 44.2-54.9) (P < 0.01). On multivariate analyses, higher socio-economic status remained a significant predictor of OS adjusting for gender, remoteness and age (HR [hazard ratio] 0.81; 95% CI 0.74-0.89; P < 0.01). Remoteness was significantly associated with improved OS after adjusting for age, gender and socio-economic status (HR 0.86; 95% CI, 0.77-0.97; P = 0.01). Older age ≥70 years compared to <70 years conferred inferior OS (HR 3.08; 95% CI, 2.64-3.59; P < 0.01). CONCLUSIONS: Our study confirmed improved survival outcomes for patients of higher socio-economic status and younger age. Future research to explain the unexpected survival benefit in patients who lived in more remote areas should examine factors including the correlation between geographical residence and eventual treatment facility as well as compare the BSWR care model to other regions' approaches.

Characteristics of cancer diagnoses and staging in South Western Victoria: a rural perspective.

OBJECTIVE: Australian states and territories have legislation mandating reporting of cancer diagnoses; however, tumour stage at diagnosis, treatment plan and associated outcomes are not routinely recorded in cancer registries for all tumour types. This study describes the Evaluation of Cancer Outcomes study that collects detailed information for patients diagnosed with cancer in south-western Victoria. DESIGN: Retrospective data collection. SETTING: Population based. PARTICIPANTS: New cancer patients within the Barwon South Western region. MAIN OUTCOME MEASURES: Cancer incidence and staging data for a regional and rural area. RESULTS: In 2009, there were 1778 primary tumours. Prominent tumour streams included prostate, breast, colon, lung, lymphoma, melanoma and rectum. Stage at diagnosis was recorded for more than 50% of patients for the tumour streams of testis, breast, bowel, renal, lung, and head and neck. Patients reporting to health centres with an on-site oncologist as part of their team had a higher rate of staging recorded at diagnosis (48.0 versus 36.9%, P=0.01). More women (55.4%) than men (41.4%) had stage-recorded. CONCLUSION: The Evaluation of Cancer Outcomes study is an important initiative that collects information about newly diagnosed cases of cancer more detailed than is currently collected by the Cancer Council of Victoria. Future studies will build on this base dataset and provide valuable insight into the regional and rural experience of treatment pathways after diagnosis. More work is needed to bring more services to our rural patients, or more education is needed to encourage the recording of tumour staging.

Radiotherapy in the Barwon South Western Region: a rural perspective.

INTRODUCTION: Cancer-related mortality rates are higher in rural areas compared with urban regions. Whether there are corresponding geographical variations in radiotherapy utilisation rates (RURs) is the subject of this study. METHODS: RURs for the regional centre of Geelong and rural areas of the Barwon South Western Region were calculated using a population-based database (2009). RESULTS: Lower RURs were observed for rural patients compared with the Geelong region for prostate cancer (15.7% vs 25.8%, P = 0.02), rectal cancer (32.8% vs 44.7%, P = 0.11), lymphoma (9.4% vs 26.2%, P = 0.05), and all cancers overall (25.6% vs 28.9%, P = 0.06). This lower rate was significant in men (rural, 19.9%; Geelong, 28.3%; P = 0.00) but not in women (rural, 33.6%; Geelong, 29.7%; P = 0.88). Time from diagnosis to radiotherapy was not significantly different for patients from the two regions. Tumour staging within the rural and Geelong regions was not significantly different for the major tumour streams of rectal, prostate and lung cancer (P = 0.61, P = 0.79, P = 0.43, respectively). A higher proportion of tumours were unstaged or unstageable in the rural region for lung (44% vs 18%, P < 0.01) and prostate (73% vs 57%, P < 0.01) cancer. CONCLUSION: Lower RURs were observed in our rural region. Differences found within tumour streams and in men suggest a complexity of relationships that will require further study.

Depression following fracture in women: a study of age-matched cohorts.

OBJECTIVES: High levels of disability, functional impairment and mortality are independently associated with fracture and depression, however the relationship between fracture and depression is uncertain. The aim of this study was to investigate whether fracture is associated with subsequent depressive symptoms in a population-based sample of women. DESIGN: A study of age-matched fracture versus non-fracture cohorts of women. SETTING: Barwon Statistical Division, southeastern Australia. PARTICIPANTS: Two samples of women aged ≥35 years were drawn from the Geelong Osteoporosis Study (GOS). The fracture cohort included women with incident fracture identified from radiology reports and the non-fracture cohort were randomly selected from the electoral roll during 1994-1996. OUTCOME MEASURE: Symptoms of depression for women with and without fracture during the 12-month period 2000-2001 were identified by self-report questionnaire based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. RESULTS: A total of 296 women with fracture (12 hip, 48 vertebral, 91 wrist/forearm, 17 upper arm, 7 pelvis, 11 rib, 62 lower leg and 48 other fractures) and 590 women without fracture were included. Associations between fracture and depression differed between younger (≤65 years) and older (>65 years) women. Age and weight-adjusted odds ratio for depression following fracture among younger women was 0.62 (0.35 to 1.11, p=0.12) and 3.33 (1.24 to 8.98, p=0.02) for older women. Further adjustment for lifestyle factors did not affect the results. CONCLUSIONS: This study demonstrated that differences in mood status exist between older and younger women following fracture and that fracture is associated with increased depression in older women. Assessment of mood status in both the short and long term following fracture in the elderly seems justified, with early detection and treatment likely to result in improved outcomes.

Rheumatoid arthritis and incident fracture in women: a case-control study.

BACKGROUND: To examine fracture incidence in women with rheumatoid arthritis (RA) for an entire geographical region of south-eastern Australia. METHODS: Women aged 35 years and older, resident in the Barwon Statistical Division (BSD) and clinically diagnosed with RA 1994-2001 were eligible for inclusion as cases (n = 1,008). The control population (n = 172,422) comprised the entire female BSD population aged 35 years and older, excluding those individuals identified as cases. Incident fractures were extracted from the prospective Geelong Osteoporosis Study Fracture Grid. We calculated rate ratios (RR) and 95% confidence intervals (CI) to compare the age-adjusted rate of fracture between the RA and non-RA populations, and used a chi-square test to compare proportions of fractures between women with and without RA, and a two-sided Mann-Whitney U-test to examine age-differences. RESULTS: Among 1,008 women with RA, 19 (1.9%) sustained a fracture, compared to 1,981 fractures sustained by the 172,422 women without RA (1.2%). Fracture rates showed a trend for being greater among women diagnosed with RA (age-adjusted RR 1.43, 95%CI 0.98-2.09, p = 0.08). Women with RA sustained vertebral fractures at twice the expected frequency, whereas hip fractures were underrepresented in the RA population (p < 0.001). RA status was not associated with the likelihood of sustaining a fracture at sites adjacent to joints most commonly affected by RA (p = 0.22). CONCLUSION: Given that women with RA have a greater risk of fracture compared to women without RA, these patients may be a suitable target population for anti-resorptive agents; however, larger studies are warranted.

A novel serogenetic approach determines the community prevalence of celiac disease and informs improved diagnostic pathways.

BACKGROUND: Changing perspectives on the natural history of celiac disease (CD), new serology and genetic tests, and amended histological criteria for diagnosis cast doubt on past prevalence estimates for CD. We set out to establish a more accurate prevalence estimate for CD using a novel serogenetic approach. METHODS: The human leukocyte antigen (HLA)-DQ genotype was determined in 356 patients with 'biopsy-confirmed' CD, and in two age-stratified, randomly selected community cohorts of 1,390 women and 1,158 men. Sera were screened for CD-specific serology. RESULTS: Only five 'biopsy-confirmed' patients with CD did not possess the susceptibility alleles HLA-DQ2.5, DQ8, or DQ2.2, and four of these were misdiagnoses. HLA-DQ2.5, DQ8, or DQ2.2 was present in 56% of all women and men in the community cohorts. Transglutaminase (TG)-2 IgA and composite TG2/deamidated gliadin peptide (DGP) IgA/IgG were abnormal in 4.6% and 5.6%, respectively, of the community women and 6.9% and 6.9%, respectively, of the community men, but in the screen-positive group, only 71% and 75%, respectively, of women and 65% and 63%, respectively, of men possessed HLA-DQ2.5, DQ8, or DQ2.2. Medical review was possible for 41% of seropositive women and 50% of seropositive men, and led to biopsy-confirmed CD in 10 women (0.7%) and 6 men (0.5%), but based on relative risk for HLA-DQ2.5, DQ8, or DQ2.2 in all TG2 IgA or TG2/DGP IgA/IgG screen-positive subjects, CD affected 1.3% or 1.9%, respectively, of females and 1.3% or 1.2%, respectively, of men. Serogenetic data from these community cohorts indicated that testing screen positives for HLA-DQ, or carrying out HLA-DQ and further serology, could have reduced unnecessary gastroscopies due to false-positive serology by at least 40% and by over 70%, respectively. CONCLUSIONS: Screening with TG2 IgA serology and requiring biopsy confirmation caused the community prevalence of CD to be substantially underestimated. Testing for HLA-DQ genes and confirmatory serology could reduce the numbers of unnecessary gastroscopies.

Prevention of aromatase inhibitor-induced bone loss with alendronate in postmenopausal women: The BATMAN Trial.

UNLABELLED: Postmenopausal women on aromatase inhibitors (AI) are at risk of aromatase inhibitor-associated bone loss (AIBL) and fractures. In 2005 Osteoporosis Australia proposed an algorithm for bisphosphonate intervention. Three hundred and three postmenopausal women with early breast cancer (EBC) were enrolled (osteoporotic, n=25; osteopaenic, n=146; normal bone mineral density (BMD), n=126). Weekly alendronate (70 mg) treatment efficacy as triggered by the algorithm in preventing bone loss was evaluated. All patients received anastrozole (1 mg daily), calcium and vitamin D. RESULTS: All osteoporotic patients received alendronate at baseline. Eleven out of the 146 (7.5%) osteopaenic patients commenced alendronate within 18 months of participation and eleven commenced after. One hundred and twenty four out of the 146 (84.9%) osteopaenic patients and all 126 with normal baseline BMD did not trigger the algorithm. At three years, lumbar spine mean BMD increased (15.6%, p<0.01) in the osteoporotic group. BMD in the osteopaenic group with early intervention significantly increased at three years (6.3%, p=0.02). No significant change was seen in the late intervention group. No change was observed in those with osteopaenia without alendronate. There was a significant drop in lumbar spine (-5.4%) and hip (-4.5%) mean BMD, in the normal BMD group, none of whom received alendronate. Fracture data will be presented. CONCLUSION: In postmenopausal women with endocrine-responsive EBC, BMD improved over time when a bisphosphonate is administered with anastrozole in osteoporotic patients using an osteoporosis schedule. Subjects with normal baseline BMD experienced the greatest BMD loss, although none became osteoporotic.

Cross-sectional analysis of association between socioeconomic status and utilization of primary total hip joint replacements 2006-7: Australian Orthopaedic Association National Joint Replacement Registry.

BACKGROUND: The utilization of total hip replacement (THR) surgery is rapidly increasing, however few data examine whether these procedures are associated with socioeconomic status (SES) within Australia. This study examined primary THR across SES for both genders for the Barwon Statistical Division (BSD) of Victoria, Australia. METHODS: Using the Australian Orthopaedic Association National Joint Replacement Registry data for 2006-7, primary THR with a diagnosis of osteoarthritis (OA) among residents of the BSD was ascertained. The Index of Relative Socioeconomic Disadvantage was used to measure SES; determined by matching residential addresses with Australian Bureau of Statistics census data. The data were categorised into quintiles; quintile 1 indicating the most disadvantaged. Age- and sex-specific rates of primary THR per 1,000 person years were reported for 10-year age bands using the total population at risk. RESULTS: Females accounted for 46.9% of the 642 primary THR performed during 2006-7. THR utilization per 1,000 person years was 1.9 for males and 1.5 for females. The highest utilization of primary THR was observed in those aged 70-79 years (males 6.1, and females 5.4 per 1,000 person years). Overall, the U-shaped pattern of THR across SES gave the appearance of bimodality for both males and females, whereby rates were greater for both the most disadvantaged and least disadvantaged groups. CONCLUSIONS: Further work on a larger scale is required to determine whether relationships between SES and THR utilization for the diagnosis of OA is attributable to lifestyle factors related to SES, or alternatively reflects geographic and health system biases. Identifying contributing factors associated with SES may enhance resource planning and enable more effective and focussed preventive strategies for hip OA.

Genome-wide association study using extreme truncate selection identifies novel genes affecting bone mineral density and fracture risk.

Osteoporotic fracture is a major cause of morbidity and mortality worldwide. Low bone mineral density (BMD) is a major predisposing factor to fracture and is known to be highly heritable. Site-, gender-, and age-specific genetic effects on BMD are thought to be significant, but have largely not been considered in the design of genome-wide association studies (GWAS) of BMD to date. We report here a GWAS using a novel study design focusing on women of a specific age (postmenopausal women, age 55-85 years), with either extreme high or low hip BMD (age- and gender-adjusted BMD z-scores of +1.5 to +4.0, n = 1055, or -4.0 to -1.5, n = 900), with replication in cohorts of women drawn from the general population (n = 20,898). The study replicates 21 of 26 known BMD-associated genes. Additionally, we report suggestive association of a further six new genetic associations in or around the genes CLCN7, GALNT3, IBSP, LTBP3, RSPO3, and SOX4, with replication in two independent datasets. A novel mouse model with a loss-of-function mutation in GALNT3 is also reported, which has high bone mass, supporting the involvement of this gene in BMD determination. In addition to identifying further genes associated with BMD, this study confirms the efficiency of extreme-truncate selection designs for quantitative trait association studies.

Area-based socioeconomic status and mood disorders: cross-sectional evidence from a cohort of randomly selected adult women.

OBJECTIVE: Data suggest there are established socio-economic disparities associated with mental health although most research has focused on individual-level indicators of socio-economic position. The aim of this study was to investigate the association between mood disorders and area-based socio-economic status (SES), and whether both ends of the SES continuum experienced increased odds for a mood disorder. METHODS: Using a clinical interview (SCID-I/NP), psychiatric history was ascertained in a population-based sample of 1095 women (20-93 years) from the Barwon Statistical Division, south-eastern Australia. SES was determined by cross-referencing residential addresses with Australian Bureau of Statistics 2006 census data for the region and categorised into three groupings of low, mid, and upper SES. The Index of Economic Resources (IER), Index of Education and Occupation (IEO), and Index of Relative Socioeconomic Advantage/Disadvantage (IRSAD) were utilised. Lifestyle factors were self-reported. RESULTS: For IER, the low SES group had a 2.0-fold increased odds of a current mood disorder compared to the mid group, after adjustment for physical activity and current anxiety (OR=2.0, 95% CI 1.0-4.1, p=0.05). This pattern was similarly observed for IEO (OR=1.8, 95% CI 0.9-3.7, p=0.1) and IRSAD (OR=1.6 95% CI 0.8-3.4, p=0.2). Those within the upper SES group showed a non-significant increase in the odds of a current mood disorder compared to the mid-group; IER (OR=1.4, 95% CI 0.8-2.5, p=0.3), IEO (OR=1.2, 95% CI 0.07-2.3, p=0.5) and IRSAD (OR=1.2, 95% CI 0.7-2.1, p=0.6). CONCLUSIONS: Women in the low SES category were most likely to have a mood disorder. Furthermore, being in an upper SES group may not be protective against mood disorders.

Changes in hip fracture rates in southeastern Australia spanning the period 1994-2007.

Hip fracture incidence rates appear to be declining in Western populations. Utilizing comprehensive incident hip fracture data from radiology reports, we determined changes in hip fracture rates in southeastern Australia between 1994-1996 and 2006-2007 for residents aged 55 years or older. During this period, the population at risk increased by 47% for men and 40% for women. Although the absolute number of hip fractures increased by 53% in men and 4.4% in women, standardized hip fracture ratios were 0.92 [95% confidence interval (CI) 0.79-1.08] and 0.69 (95% CI 0.62-0.77), respectively. Marked reductions in hip fracture rates were observed for women: 32% for ages 75 to 84 years and 29% for ages 85 years or older. Data from the Geelong Osteoporosis Study were used to identify changes in body composition and lifestyle that might have influenced hip fracture risk in women during this period. Between 1993-1997 and 2004-2008, there was an increase in adiposity, bone mineral density (BMD), healthy lifestyles, and exposure to bone-active drugs; use of hormone therapy declined. Thus hip fracture incidence rates have decreased from the mid-1990 s to the mid-2000 s, the effect being greater among women. Our data also suggest that the recent increase in adiposity and consequent increase in BMD at the hip may have contributed to this decline. However, improved efficacy and increased uptake of antifracture drug treatments, other cohort effects, or other environmental influences cannot be excluded.

Paracetamol (acetaminophen) use, fracture and bone mineral density.

Paracetamol is the most widely prescribed simple analgesic and antipyretic. It exerts its effects via cyclooxygenase and endocannabinoid pathways, which may affect signalling in bone cells and hence influence bone metabolism. Given the high rates of paracetamol use in the community and the evidence linking its mechanism of action to bone metabolism, we aimed to investigate the association between paracetamol use, fracture, and bone mineral density (BMD) in women participating in the Geelong Osteoporosis Study (GOS). Cases (n = 569) were women aged ≥ 50 years identified from radiological reports as having sustained a fracture between 1994 and 1996. Controls (n = 775) were women without fracture recruited from the same region during this period. BMD was measured at the spine, hip, total body and forearm using dual energy absorptiometry. Medication use, medical history and lifestyle factors were self-reported. There were 69 (12.1%) paracetamol users among the cases and 63 (8.1%) among the controls. Paracetamol use increased the odds for fracture (OR = 1.56, 95%CI 1.09-2.24, p = 0.02). Adjustment for BMD at the spine, total hip and forearm did not confound the association. However, incorporating total body BMD into the model attenuated the association (adjusted OR = 1.46, 95%CI 1.00-2.14, p = 0.051). Further adjustment for age, weight, physical activity, smoking, alcohol, calcium intake, medication use, medical conditions, falls and previous fracture did not explain the association. These data suggest that paracetamol use is a risk factor for fracture, although the mechanism of action remains unclear.

Fracture risk score and absolute risk of fracture.

PURPOSE: To report the 5- and 10-year absolute risk of fracture associated with the previously reported fracture risk (FRISK) score. MATERIALS AND METHODS: All participants gave written, informed consent, and the Barwon Health Human Research Ethics Committee approved the study. An age-stratified population-based sample of women aged 60 years and older (n = 600) was recruited during 1994-1996. FRISK scores of 0-10 incorporating bone mineral density (BMD) at two sites (hip and spine), falls scores in the previous 12 months of 1-4, weight, and number of fractures as an adult were calculated. Fractures of the hip, spine, humerus, and wrist were ascertained during a median follow-up period of 9.6 years (interquartile range, 6.6-10.5). The cumulative probability of fracture at 5 and 10 years after baseline measurements was calculated by using actuarial methods. The utility of this model was compared with other FRISK algorithms, including the World Health Organization FRISK assessment tool FRAX designed for United Kingdom and that designed for the United States and the Garvan nomogram (Australia). RESULTS: This study supplies the 5- and 10-year absolute risk of fracture associated with all levels of the FRISK score. While there are modest differences in absolute risk of fracture seen for different numbers of prior fractures, the more marked differences occur across the different categories of falls scores and different categories of BMD. The receiver operating characteristic curves showed no significant difference in area under the curve for all four absolute risk of fracture algorithms. CONCLUSION: Absolute risk of fracture can be determined by using readily obtainable clinical information that may aid treatment decisions.

The association between depressive and anxiety symptoms and bone mineral density in the general population: the HUNT Study.

BACKGROUND: Psychiatric disorders may be risk factors for reduced bone mineral density (BMD). Longitudinal evidence is limited and this is yet to be examined among community-dwelling adults with anxiety. We aimed to investigate the cross-sectional and longitudinal relationships between anxiety and depressive symptoms and BMD. METHOD: This study examined data from the second Nord-Trondelag Health Study (1995-1997; 1194 men and 7842 women) and a follow-up conducted in 2001 (697 men and 2751 women). Symptomatology was ascertained using the Hospital Anxiety and Depression Scale and BMD was measured at the forearm using single-energy X-ray absorptiometry. Information on medication use and lifestyle was self-reported, and these, together with anthropometric measures were tested in multivariate analyses. RESULTS: In men, adjusted BMD was 2.6% lower at the ultradistal forearm for those with depressive symptoms and 2.6% lower at the ultradistal and 2.0% lower at the distal forearm for those with anxiety symptoms. In women, adjusted BMD at the distal and ultradistal forearm was lower for heavier women with depressive symptoms but this relationship diminished with decreasing weight. Forearm BMD was similar for women with or without anxiety symptoms. Longitudinally, neither depressive nor anxiety symptoms were associated with bone loss over 4.6 years. LIMITATIONS: Findings cannot be generalised to other skeletal sites and a longer follow-up period may be necessary to detect differences in bone loss. CONCLUSIONS: These results indicate that depressive and anxiety symptoms are cross-sectionally associated with reduced BMD. These findings provide further evidence to support monitoring BMD in individuals diagnosed with psychiatric illness.

Habitual physical activity and the risk for depressive and anxiety disorders among older men and women.

BACKGROUND: Regular physical activity is generally associated with psychological well-being, although there are relatively few prospective studies in older adults. We investigated habitual physical activity as a risk factor for de novo depressive and anxiety disorders in older men and women from the general population. METHODS: In this nested case-control study, subjects aged 60 years or more were identified from randomly selected cohorts being followed prospectively in the Geelong Osteoporosis Study. Cases were individuals with incident depressive or anxiety disorders, diagnosed using the Structured Clinical Interview for DSM-IV-TR (SCID-I/NP); controls had no history of these disorders. Habitual physical activity, measured using a validated questionnaire, and other exposures were documented at baseline, approximately four years prior to psychiatric interviews. Those with depressive or anxiety disorders that pre-dated baseline were excluded. RESULTS: Of 547 eligible subjects, 14 developed de novo depressive or anxiety disorders and were classified as cases; 533 controls remained free of disease. Physical activity was protective against the likelihood of depressive and anxiety disorders; OR = 0.55 (95% CI 0.32-0.94), p = 0.03; each standard deviation increase in the transformed physical activity score was associated with an approximate halving in the likelihood of developing depressive or anxiety disorders. Leisure-time physical activity contributed substantially to the overall physical activity score. Age, gender, smoking, alcohol consumption, weight and socioeconomic status did not substantially confound the association. CONCLUSION: This study provides evidence consistent with the notion that higher levels of habitual physical activity are protective against the subsequent risk of development of de novo depressive and anxiety disorders.

Association of high-sensitivity C-reactive protein with de novo major depression.

BACKGROUND: Although there is cross-sectional evidence that changes in the immune system contribute to the pathophysiology of depression, longitudinal data capable of elucidating cause and effect relationships are lacking. AIMS: We aimed to determine whether subclinical systemic inflammation, as measured by serum high-sensitivity C-reactive protein (hsCRP) concentration, is associated with an increased risk of de novo major depressive disorder. METHOD: Major depressive disorder was diagnosed using a clinical interview (SCID-I/NP). This is a retrospective cohort study; from a population-based sample of 1494 randomly selected women recruited at baseline during the period 1994-7, 822 were followed for a decade and provided measures of both exposure and outcome. Of these women, 644 (aged 20-84 years) had no prior history of depression at baseline and were eligible for analysis. RESULTS: During 5827 person-years of follow-up, 48 cases of de novo major depressive disorder were identified. The hazard ratio (HR) for depression increased by 44% for each standard deviation increase in log-transformed hsCRP (ln-hsCRP) (HR = 1.44, 95% CI 1.04-1.99), after adjusting for weight, smoking and use of non-steroidal anti-inflammatory drugs. Further adjustment for other lifestyle factors, medications and comorbidity failed to explain the observed increased risk for depression. CONCLUSIONS: Serum hsCRP is an independent risk marker for de novo major depressive disorder in women. This supports an aetiological role for inflammatory activity in the pathophysiology of depression.

Patterns of alcohol use and associated physical and lifestyle characteristics according to new Australian guidelines.

OBJECTIVE: To describe the pattern of alcohol consumption and associated physical and lifestyle characteristics in a population-based sample of Australian men. METHOD: A community-based age-stratified random sample of 1420 men (median age 56 years, range 20-93) participating in the Geelong Osteoporosis Study, an epidemiological study set in south-eastern Australia. Daily alcohol intake was ascertained from a detailed food frequency questionnaire and categorized according to the Australian National Health and Medical Research Council 2009 guidelines (non-drinkers, greater than zero but ≤ 2 drinks per day, > 2 drinks per day), with a standard drink equivalent to 10 g of ethanol. Anthropometry was measured and lifestyle factors self-reported. Body composition was determined using dual energy absorptiometry. Socio-economic status was categorized according to the Australian Bureau of Statistics data. Results were age standardized to the Australian male population figures. RESULTS: The median daily ethanol consumption was 12 g (IQR 2-29) per day with a range of 0-117 g/day. The age-standardized proportion of non-drinkers was 8.7%, 51.5% consumed up to two drinks per day (≤ 20 g ethanol/day), and 39.9% exceeded 2 standard drinks per day (> 20 g ethanol/day). Alcohol consumption was positively associated with cigarette smoking, weight, higher SES and inversely with age and physical activity. CONCLUSIONS: Approximately, 40% of Australian men consume alcohol at levels in excess of current recommendations, which in combination with other risk factors may adversely impact upon health.
