A systematic review of personality and musculoskeletal disorders: evidence from general population studies.

Introduction: We conducted a systematic review to evaluate the quality and extent of evidence on associations between personality disorders (PDs) and musculoskeletal disorders (MSDs) in population-based studies, since these disorders are leading causes of disease burden worldwide. Methods: A search strategy of published, peer-reviewed and gray literature was developed in consultation with a liaison librarian and implemented for Embase, CINAHL Complete, Medline Complete, and PsycINFO via the EBSCOhost platform from 1990 to the present and CORDIS and ProQuest Dissertations & Theses Global, respectively. The inclusion criteria were as follows: I) general population participants aged ≥15 years; II) self-report, probable PD based on positive screen, or threshold PD according to the DSM-IV/5 (groupings: any, Clusters A/B/C, specific PD) or ICD-10/11; III) MSDs identified by self-report or ICD criteria (arthritis, back/neck conditions, fibromyalgia, osteopenia/osteoporosis) and III) cohort, case-control, and cross-sectional study designs. Two reviewers independently screened articles and extracted the data. Critical appraisal was undertaken using the Joanna Briggs Institute checklists for systematic reviews of etiology and risk. A descriptive synthesis presents the characteristics of included studies, critical appraisal results, and descriptions of the main findings. This review adhered to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Results: There were 11 peer-reviewed, published articles included in this review (n = 9 cross-sectional and n = 2 case-control studies); participants were ≥18 years in these studies. No published gray literature was identified. Semi-structured interviews were the most common method to ascertain PDs; all studies utilized self-reported measures to identify MSDs. Overall, we detected limited and conflicting evidence for associations between PDs and MSDs. Discussion: The main result may be explained by lack of population-based longitudinal evidence, heterogenous groupings of PD, and few comparable cross-sectional and case-control studies. Strengths of the review include a comprehensive search strategy and a discussion of mechanisms underlying possible associations between PDs and MSDs. Conclusions: The quality of most studies included in this review that examined associations between PD and MSDs in general population adults was high. However, the results demonstrated limited and conflicting evidence for these associations, in part, due to lack of comparable evidence, which should be addressed in future research.

Lithium use and bone health in women with bipolar disorder: A cross-sectional study.

INTRODUCTION: Several psychiatric disorders and medications used to treat them appear to be independently associated with skeletal deficits. As there is increasing evidence that lithium possesses skeletal protective properties, we aimed to investigate the association between lithium use and bone health in a group of women with bipolar disorder. METHOD: Women with bipolar disorder (n = 117, 20+ years) were recruited from south-eastern Australia. Bipolar disorder was confirmed using a clinical interview (SCID-I/NP). Bone mineral density (BMD; g/cm2 ) was measured at the spine, hip and total body using dual-energy x-ray absorptiometry and low bone mass determined by BMD T-score of <-1.0. Weight and height were measured, socioeconomic status (SES) determined and information on medication use and lifestyle factors self-reported. Linear and logistic regression were used to test associations between lithium and (i) BMD and (ii) low bone mass, respectively. RESULTS: Thirty-five (29.9%) women reported current lithium use. Lithium users and non-users differed in regard to SES and BMD; otherwise, groups were similar. After adjustments, mean BMD among lithium users was 5.1% greater at the spine (1.275 [95% CI 1.229-1.321] vs. 1.214 [1.183-1.244] g/cm2 , p = 0.03), 4.2% greater at the total hip (0.979 [0.942-1.016] vs. 0.938 [0.910-0.966] g/cm2 , p = 0.03) and 2.2% greater at the total body (1.176 [1.148-1.205] vs. 1.150 [1.129-1.171] g/cm2 , p = 0.08) compared to participants not receiving lithium. Lithium users were also less likely to have low bone mass (22.9% vs. 43.9%, p = 0.031). Associations persisted after adjustment for confounders. CONCLUSION: These data suggest lithium is associated with greater BMD and reduced risk of low bone mass in women with bipolar disorder. Research into the underlying mechanisms is warranted.

The diagnostic cut-off points for components of sarcopenia in Finnish Caucasian women: A retrospective cross-sectional study.

Objectives: To determine the diagnostic cut-off values of components for sarcopenia in Caucasian women. Methods: The present retrospective cross-sectional study based on the REFERENCE sample included 400 healthy women aged 20 to 40 years, and the OSTPRE sample included 344 women aged 63 to 75. The subjects of the OSTPRE population were re-measured five and ten years later after the baseline. Both samples underwent grip strength (GS), quadriceps strength (QS), and total-body DXA (TB-DXA) measurements, from which Relative Skeletal Muscle Mass Index (RSMI) was calculated. Results: In the REFERENCE population, the -1 SD / -2 SD cut-off points were for RSMI 5.8 kg/m2 / 5.1 kg/m2, for GS 32.0 kg / 26.4 kg, and for QS 39.8 kg / 29.8 kg. The prevalence of under -2 SD distributions in REFERENCE were: RSMI 1.8%, GS 1.3%, and QS 2.0%, and in OSTPRE (15/20/25 years measurements): RSMI 1.2 %/1.9 %/0.5 %, GS 52.2%/42.3%/48.8%, and QS 47.4%/55.2%/not available. The distributions of GS and QS were statistically significantly different between REFERENCE and all OSTPRE measurement points (p<0.001 in Chi-squared). Conclusions: The diagnostic cut-offs for components of sarcopenia are RSMI 5.1 kg/m2, grip strength 26.4 kg, and quadriceps strength 29.8 kg in Finnish Caucasian women.

Effectiveness of exercise on fall prevention in community-dwelling older adults: a 2-year randomized controlled study of 914 women.

BACKGROUND: Communal exercise interventions may help prevent falls and injuries. However, pragmatic trials demonstrating the effectiveness of such strategies are sparse. METHODS: We determined whether a cost-free 12-month admission to the city's recreational sports facilities including initial 6 months of supervised weekly gym and Tai Chi sessions decreases the number of falls and related injuries. The mean (SD) follow-up time was 22·6 (4.8) months in 2016-19. A total of 914 women from a population-based sample with a mean age of 76.5 (SD 3.3, range 71.1-84.8) years were randomized into exercise intervention (n = 457) and control (n = 457) groups. Fall information was collected through biweekly short message (SMS) queries and fall diaries. Altogether 1,380 falls were recorded for the intention-to-treat analysis, with 1,281 (92.8%) being verified by telephone. RESULTS: A 14.3% fall rate reduction was detected in the exercise group (Incidence rate ratio (IRR) = 0.86; CI 95% 0.77-0.95) compared with the control group. Approximately half of the falls caused moderate (n = 678, 52.8%) or severe (n = 61, 4.8%) injury. In total, 13.2% (n = 166) of falls (including 73 fractures) required medical consultation with a 38% lower fracture rate in the exercise group (IRR = 0.62; CI 95% 0.39-0.99). Overall, the greatest reduction of 41% (IRR = 0.59; CI 95% 0.36-0.99) was observed in falls with severe injury and pain. CONCLUSIONS: A community-based approach for a 6-month exercise period combined with a 12-month free use of sports premises can reduce falls, fractures and other fall-related injuries in aging women.

Falls in community-dwelling women with bipolar disorder: a case-control study.

BACKGROUND: Falls are a common occurrence in psychiatric hospital settings, however population-based research among individuals with psychiatric disorders, in particular bipolar disorder (BD) is scant. Thus, we aimed to investigate falls risk in community-dwelling women diagnosed with BD. METHODS: Women with BD (cases, n = 119) were recruited from health care settings located in southeast Victoria, Australia. Age-matched controls (n = 357, ratio 3:1) without BD were participants in the Geelong Osteoporosis Study drawn from the same geographical region. Lifetime history of BD was identified by semi-structured clinical interview (SCID-IV/NP). Previous 12-month falls data were obtained via questionnaire. Information on mobility, alcohol use, general health, medication use, blood pressure, body mass index, socioeconomic status and use of a walking aid was collected. Generalised Estimating Equations, binary and ordinal logistic regression were used to determine the odds ratio (OR) and 95% confidence interval (CI) for falls following adjustment for confounders. RESULTS: During the 12-month period, 34 (28.6%, median age 48.4 yr) cases and 70 (19.6%, median age 49.1 yr) controls reported one fall; 22 (18.5%) cases and 18 (5.0%) controls reported ≥ two falls (p < 0.001). Cases had 2.5-fold increased odds of at least one fall and 2.9-fold increased likelihood of increasing falls categories (0 vs. 1 vs. 2 +), compared to controls [adjOR 2.5, 95%CI (1.8, 3.4), adjOR OR 2.9, 95%CI (2.0, 4.1)]. CONCLUSION: Risk of falls was greater among women with BD. Balance training could be a research and clinical focus for falls prevention programs among women with bipolar disorder to prevent the detrimental outcomes associated with falling.

Comparing self-reports to national register data in the detection of disabling mental and musculoskeletal disorders among ageing women.

BACKGROUND: Self-reports of diseases are used in research due to time and cost efficiency. Mental disorders (MDs) and musculoskeletal disorders (MSDs) are the leading causes of global disability. AIMS: To investigate how self-reports detect physician-diagnosed severe MDs and MSDs in postmenopausal women. METHODS: In the population-based OSTPRE cohort, 1466 women (aged 57-66) had received a permanent work disability pension (DP) due to 'MDs only' (n = 336), 'MSDs only' (n = 926) or 'MDs + MSDs' (n = 204) by the end of 1998 and responded to a postal enquiry in 1999. In 2009, 1029 women responded to a follow-up enquiry. Self-reports were cross-checked against register data on DPs. RESULTS: In 1999, 47 % of the participants in the 'MDs only' and 21 % in the 'MDs + MSDs' reported DPs due to MDs, whereas 75 % in the 'MSDs only' and 67 % in the 'MDs + MSDs' reported DPs due to MSDs. By 2009, this discrepancy increased, with the respective figures being 34 % and 19 % for MDs and 75 % for both MSDs groups. In 1999, older age was related to non-reporting in the three groups (each: p ≤ 0.001). CONCLUSION: Self-reports grossly underestimate the prevalence of disabling MDs and considerably that of MSDs among ageing women. Thus, additional sources of information are needed.

Bipolar disorder and bone health: A case-control study.

BACKGROUND: Bipolar disorder (BD) is associated with significant psychological and physical comorbidity. Yet little is known about the bone health of individuals with BD. Thus, we aimed to investigate the association between BD and bone health in a population-based sample of women. METHODS: Women with a history of BD (cases; n = 117) were recruited from public and private health care settings and controls, without BD, were drawn from the Geelong Osteoporosis Study (n = 909). BD was identified using a semi-structured clinical interview (SCID-I/NP). Bone mineral density (BMD) was measured at the spine, femoral neck and total body using dual energy x-ray absorptiometry, and bone quality by quantitative heel ultrasound and included the following parameters: Speed of Sound (SOS), Broadband Ultrasound Attenuation (BUA) and Stiffness Index (SI). Weight and height were measured and information on medication use and lifestyle was obtained. RESULTS: Adjusted mean BMD among the cases was 4.3% lower at the hip and 1.6% lower at the total body compared to controls. Age was an effect modifier at the spine. Among women <50 years, mean spine BMD for cases was 3.5% lower than controls. No differences in spine BMD for those ≥50 years were detected. Cases also had a 1.0%, 3.2% and 7.8% lower adjusted mean SOS, BUA and SI compared to controls, respectively. LIMITATIONS: Course, chronicity and recovery of BD were not explored in relation to bone health. CONCLUSION: These data suggest BD is associated with low bone quantity and quality in women. Replication and research into underlying mechanisms is warranted.

Exploring the comorbidity between personality and musculoskeletal disorders among adults: A scoping review.

Introduction: There is growing awareness of the comorbidity between mental and musculoskeletal disorders (MSDs) and their associated burden. We aimed to explore what is known regarding the existing epidemiological clinical-and population- based literature on the comorbidity between personality disorders (PDs) and MSDs specifically. In addition, we aimed to investigate their associated burden by examining a range of outcomes including morbidity/mortality, patient- and clinical-reported outcomes, work-related outcomes, hospital admissions, and financial costs. Finally, we sought to identify gaps in the literature and provide recommendations for further research. Methods: Studies with participants 15 years of age were eligible. Categorical PDs/features (DSM-III/IV/5 or ICD 9/10), identified by a health care professional, medical records, diagnostic interviews, or self-administered questionnaires. The definitions/groupings of MSDs were guided by the ICD-10 including conditions of the back, joints, and soft tissue, and disorders of bone density and structure. Published peer-reviewed and gray literature were considered. Eligible study designs were cohort, case-control, and cross-sectional studies, and existing reviews of observational studies. Identification and selection of articles, data extraction and the presentation of the results was conducted according to the Joanna Briggs Institute methodological guidance and the PRISMA extension for scoping reviews. Results: In total, 57 articles were eligible including 10 reviews and 47 individual studies. Across clinical and population settings, we detected evidence of comorbidity between PDs and chronic back/neck/spine conditions, arthritis, and fibromyalgia, and emerging evidence of associations between PDs and reduced bone mineral density. In terms of knowledge gaps, the burden associated with PDs and MSDs is poorly understood, as is their underlying mechanisms. Discussion: This scoping review might prompt further research into PDs and MSDs as separate groups of disorders, along with their comorbidity and the mechanisms that may link them.

Associations between personality and musculoskeletal disorders in the general population: A systematic review protocol.

There is growing evidence of the comorbidity between personality disorder (PD) and musculoskeletal disorders (MSDs). However, there are no systematic reviews including critical appraisal and meta-analyses that identify, evaluate, and synthesize the available evidence on these associations. Therefore, we present here a protocol of the methodology to undertake a systematic review, with the objective to evaluate associations between PD and MSDs in epidemiological population-based studies. A systematic review of observational studies will be conducted. A complete search strategy will be developed in consultation with a health librarian. To identify peer-reviewed literature, the search will be translated for, and implemented in Medline Complete, CINAHL Complete, and PsycINFO via the EBSCOhost platform from 1990 to the present. Gray literature will be identified. Studies will be eligible if they examine general population participants aged 15 years and over. Associations of interest are the presence of threshold or positive screen according to the DSM-V/5 (groupings: any, Clusters A, B, C, specific PD) or ICD-10 for PD in relation to arthritis, back/neck conditions, fibromyalgia, osteopenia/osteoporosis, and/or "any" of these MSDs. Data extraction and critical appraisal will be conducted in line with the Joanna Briggs Institute (JBI) guidance for systematic reviews of etiology and risk. The results from all studies will be presented in tables, text, and figures. A descriptive synthesis will present the characteristics of included studies, critical appraisal results, and descriptions of the main findings. Where appropriate, meta-analyses will be performed. If heterogeneity (e.g., I 2 = 50%) is detected, subgroup/sensitivity analysis may be used to explore the possible sources. The systematic review does not require ethics approval. The proposed systematic review will strengthen the evidence base on what is known regarding associations between PD and MSDs by identifying, evaluating, and synthesizing the findings of existing observational studies including meta-analyses, where appropriate.

Urban RCT participants were healthier than non-participants or rural women.

OBJECTIVE: To investigate sociodemographic characteristics and physical and mental health indicators between participants and nonparticipants of a large-scale 2-year exercise RCT including noninvited women living in nearby rural area in Finland. STUDY DESIGN AND SETTING: From a previous OSTPRE study cohort, 914 women (aged 72-84) participated in Kuopio Fall Prevention Study in 2016-2019. The participants were compared to non-participants (n = 4,536) and noninvited OSTPRE women (n = 7,119) living outside the urban recruitment area. RESULTS: Participants were younger (P< 0.001) with higher education (P< 0.001) and had more often regular hobbies (P< 0.001) and physical exercising (P< 0.001) than nonparticipants or noninvited. They reported better functional capability (P< 0.001), mental (P< 0.001) and subjective health (P< 0.001), lower number of medications (P< 0.001), less fear of falls (P< 0.001), but more frequent falls (P= 0.002) and more often musculoskeletal diseases (P= 0.006).  Participants also showed better functional capacity in the clinical measurements. In register analysis, urban-rural differences in the prevalence of diseases were detected. CONCLUSION: In population-based exercise interventions, participants are more likely to be better off in respect to physical and mental wellbeing, functional capability and sociodemographic status. Recruiting participants only from cities increases unavoidable selection bias due to urban-rural differences which should be noticed when interpreting and generalizing RCT results. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov identifier NCT02665169.

Exploring the comorbidity of musculoskeletal and personality disorders among adults: a scoping review protocol.

BACKGROUND: Separately, mental and musculoskeletal disorders (MSDs) are prevalent across the life course and are leading contributors to disability worldwide. While people with personality disorder (PD) have been shown to have an increased risk of certain physical health comorbidities-associations with MSDs have not been thoroughly explored. The proposed scoping review aims to explore the existing clinical- and population-based literature on the comorbidity of PD and MSDs among adults ≥ 18 years and the burden associated with their comorbidity, identify knowledge gaps on this topic, and propose recommendations for future research. METHODS: This protocol describes the methodology to undertake the scoping review. It is guided by Arksey and O'Malley's framework and the extensions recommended by the Joanna Briggs Institute. A comprehensive search strategy will be used to identify relevant articles, which will be underpinned by Population, Concept, and Context (PCC) inclusion criteria. One author will perform the search and two authors will independently screen titles/abstracts followed by a full-text review for articles considered relevant. The supervising author will confirm the final selection of articles to be included. One author will extract relevant information from the articles using a predetermined charting form, while a second will perform validation of all information entered. DISCUSSION: Information will be synthesised to inform a discussion of what is known regarding associations between PD and MSDs, and the burden associated with their comorbidity in different contexts, with future research directions proposed. SYSTEMATIC REVIEW REGISTRATION: This protocol is registered in Open Science Framework Registries ( https://osf.io/mxbr2/ ).

Metabolite Profiling of Osteoporosis and Atherosclerosis in Postmenopausal Women: A Cross-Sectional Study.

PURPOSE: Atherosclerosis (AS) and osteoporosis (OP) are common causes of morbidity and mortality in postmenopausal women and are connected via an unknown mechanistic link. Metabolite profiling of blood samples may allow the identification of new biomarkers and pathways for this enigmatic association. PATIENTS AND METHODS: We studied the difference in 148 metabolite levels from serum samples in postmenopausal women with AS and OP compared with those in healthy participants in this cross-sectional study. Quantitative AS was assessed by carotid artery intima-media thickness (cIMT) and carotid artery calcifications (CACs) by ultrasound, as well as OP by femoral neck (FN) bone mineral density (BMD) and 148 metabolic measures with high-throughput proton (1H) nuclear magnetic resonance (NMR) in serum samples from 280 postmenopausal (PM) women. Subjects were a randomly selected subsample from the population-based Kuopio Osteoporosis Risk Factor and Prevention (OSTPRE) study. The final study population included the following groups: OP with CAC (n=16, group I), non-OP with no CAC (n=59, group II), high cIMT tertile with OP (n=11, group III) and low cIMT tertile without OP (n=48, group IV). RESULTS: There were differences in several metabolite levels between groups I and II. The acetate level was lower in group I compared to that in group II (group I mean ± SD: 0.033 ± 0.0070; group II: 0.041 ± 0.014, CI95%: 0.018‒0.15, p=0.014). The result was similar with diacylglycerol (p=0.002), leucine (p=0.031), valine (p=0.022) and several very low-density lipoprotein (VLDL) metabolite levels, which were lower in group I compared to those in group II. However, no associations were found in adjusted analyses with total body (TB) fat mass (FM), age and statin use (p>0.05). CONCLUSION: Our novel study found differences in the metabolite profiling of altered amino acid and lipoprotein metabolism in participants with OP and AS compared with those in healthy women. The causative mechanisms remain unknown and further studies are needed.

Personality Disorder and Physical Health Comorbidities: A Link With Bone Health?

We examined whether personality disorders (PDs) (any, cluster A/B/C) were associated with bone mineral density (BMD) in a population-based sample of Australian women (n = 696). Personality and mood disorders were assessed using semi-structured diagnostic interviews. BMD was measured at the spine, hip, and total body using dual-energy x-ray absorptiometry (GE-Lunar Prodigy). Anthropometrics, medication use, physical conditions, and lifestyle factors were documented. The association between PDs (any, cluster A/B/C) and BMD (spine/hip/total body) was examined with multiple linear regression models. The best models were identified by backward elimination including age, weight, physical activity, smoking status, alcohol consumption, dietary calcium intake, mood disorders, physical multimorbidity, socioeconomic status, and medications affecting bone. The variables were retained in the model if p < 0.05. All potential interactions in final models were tested. Those with cluster A PD, compared to those without, had 6.7% lower hip BMD [age, weight adjusted mean 0.853 (95% CI 0.803-0.903) vs. 0.910 (95% CI 0.901-0.919) g/cm2, p = 0.027] and 3.4% lower total body BMD [age, weight, smoking, alcohol, calcium adjusted mean 1.102 (95% CI 1.064-1.140) vs. 1.139 (95% CI 1.128-1.150) g/cm2, p = 0.056]. No associations were observed between cluster B/C PDs and hip/total body BMD or between any of the PD clusters and spine BMD. To our knowledge, this study is the first to investigate the bone health of women with PD in a population-based sample. Given the paucity of literature, replication and longitudinal research including the examination of underlying mechanisms and sex differences are warranted.

Physical activity and Baltic Sea diet are interactively related to higher life satisfaction in community-living older Finnish women: OSTPRE-FPS study.

A healthful diet and sufficient physical activity (PA) are related to several health outcomes. However, there is a paucity of data on the association of PA and dietary pattern with life satisfaction (LS) in the older adults aged ≥65. The present study investigated the independent and combined association of PA and Baltic Sea diet (BSD) score with LS in older Finnish women. Subjects were 554 women aged 65-72 years from the Osteoporosis Risk Factor and Prevention - Fracture Prevention Study. Women reported the hours and type of PA and lifestyle factors via questionnaires and dietary intake using the 3-d food record. Adequate PA was considered according to WHO recommendation: PA = 0, 0 < PA < 2·5 and ≥2·5 h/week. BSD score was categorised as <13 or ≥13 based on the median score. LS was self-reported using LS scale with four items on current 'interest', 'happiness in life', 'ease of living' and 'feelings of loneliness' (range: 4-20, lower score representing higher satisfaction). After adjusting for the confounders, PA was statistically significantly associated with lower LS score (ß coefficient = -0·207, P = 0·001), where women with PA ≥ 2·5 h/week had the lowest LS score followed by women with 0 < PA < 2·5 and PA = 0 (Pfor trend = 0·020). Association between BSD and LS was NS. Only among women with BSD score ≥ 13, but not BSD < 13, PA ≥ 2·5 h/week was statistically significantly associated with lower LS score (mean = 9·3), followed by 0 < PA < 2·5 (mean = 9·9) and PA = 0 groups (mean = 11·8) (Pfor trend = 0·033). In conclusion, adequate PA according to WHO recommendation independently and in combination with higher BSD score may be associated with higher LS in older women.

Depressive disorders, anxiety disorders and subjective mental health in common musculoskeletal diseases: A review.

Globally, musculoskeletal diseases (MSDs) and mental disorders are the leading causes of disability, but their mutual relationships have been little studied. The objective of the current review is to summarize the evidence on the relationships between depressive and anxiety disorders, subjective mental health and common MSDs in adults aged 45 years and over. A review of studies published in English, identified using MEDLINE, was conducted. Search terms included spinal stenosis, intervertebral disc displacement, osteoarthritis, osteoporosis, depressive disorder, anxiety disorders, mental health, subjective well-being, subjective quality of life, life satisfaction and personal satisfaction. A total of 287 records were initially identified, and an additional 190 records were identified from their reference lists. Eight studies were considered eligible and were, thus, included in the current review. The included studies reported that: 1) major depressive disorder is associated with chronic back pain; 2) anxiety disorders are associated with cervical or lumbar disc herniation; 3) mood and anxiety disorders are associated with lower bone mineral density in men; 4) life satisfaction and its improvement prevent bone loss in postmenopausal women; and 5) quality of life reduces progressively as the number of osteoporotic fractures increases. In conclusion, common MSDs are associated with mental disorders and subjective mental health in adults aged 45 years or more, but longitudinal research is needed.

Randomised controlled trial (RCT) study design for a large-scale municipal fall prevention exercise programme in community-living older women: study protocol for the Kuopio Fall Prevention Study (KFPS).

INTRODUCTION: Falls are a substantial health problem in seniors, causing fractures and being the leading cause of fatal injuries. The benefits of physical activity in fall prevention have been shown in randomised controlled trials (RCTs) in small cohorts (eg, ≤200 persons), but there is a gap between the known health effects of exercise and the large-scale implementation of effective activity in communities. Mental health and subjective well-being (SWB) should also be studied since they are strongly related to healthy ageing. Thus far, the proven efficacy of communal strategies to reduce falls and improve healthy ageing is sparse. METHODS AND ANALYSIS: In 2016, a 2-year RCT was launched in Kuopio, Finland to estimate the efficacy of a large, population-based, fall prevention exercise programme in community-living older women (born 1932-1945). Both the intervention and control group (n=457+457) receive health education. The intervention group is also offered free 6-month supervised training courses (weekly gym training and Taiji sessions), followed by a free 6-month unsupervised use of exercise facilities, as well as unsupervised low-cost exercise is also offered for another 12 months. During the whole 24-month follow-up, controls are free to pursue all their normal physical activities. Both study groups undergo the study measurements three times. Outcome measures include recording of falls, injuries, bone mineral density, changes in health and functional status and cognitive performance, deaths and SWB. Finally, the cost-effectiveness and cost-utility analysis will be conducted from the societal view. The main analyses comparing outcomes between study groups will be conducted using the intention to treat principle. ETHICS AND DISSEMINATION: The study has been reviewed and approved by the Research Ethics Committee of the Hospital District of North Savo. All regulations and measures of ethics and confidentiality are handled in accordance with the Declaration of Helsinki. TRIAL REGISTRATION NUMBER: NCT02665169; Pre-results.

High Postural Sway Is an Independent Risk Factor for Osteoporotic Fractures but Not for Mortality in Elderly Women.

The aim of this prospective cohort study was to investigate the independent effect of postural sway on overall fracture and osteoporotic fracture risk after controlling for other established fracture risk factors. As a secondary outcome, mortality was also investigated. The study sample is a stratified random sample of 1568 women born between 1932 and 1941, residing in Kuopio province, eastern Finland. Fracture data were obtained through study questionnaires and verified through hospital records. Mortality data were verified through the National Registry. Using static posturography, postural sway was recorded for 1568 women at the fifth year of follow-up in 1994 through 1997. Mediolateral (ML), anteroposterior (AP), and total sway parameters were used for analysis. Mean follow-up time for any fractures, osteoporotic fractures, and mortality was 10.6, 11.4, and 17.5 years, respectively. After adjustment, subjects in the highest quartile of ML sway (HR, 2.0; 95% CI, 1.5 to 2.8) and total sway (HR, 1.6; 95% CI, 1.2 to 2.2) had a higher risk for any fracture. Osteoporotic fracture risk was also higher in the fourth quartile of ML sway (HR, 1.9; 95% CI, 1.1 to 3.0) and total sway (HR, 1.7; 95% CI, 1.0 to 2.8). The models were adjusted for fracture risk assessment tool risk factors and leg-extension strength. Further, women having both lowest bone density and highest postural sway were at 4.9 (95% CI, 2.6 to 9.5) times higher risk of overall fracture and 11.8 (95% CI, 2.7 to 51.3) times higher risk for osteoporotic fracture in comparison with subjects having highest bone density and lowest postural sway. The association between postural sway and mortality was not significant after adjustment. In conclusion, high postural sway is an independent risk factor for any fractures as well as for osteoporotic fractures. A combination of low bone density and high postural sway poses even higher fracture risk than either factor alone. Postural sway does not predict mortality independently. © 2019 American Society for Bone and Mineral Research.

Effects of ethinyl estradiol-containing oral contraception and other factors on body composition and muscle strength among young healthy females in Finland-A cross-sectional study.

OBJECTIVE: The aim of this cross-sectional study was to determine the association of hormonal contraception and other life-style factors and habits affecting body composition (BC) and muscle strength. STUDY DESIGN: We measured the body composition of 400 healthy Finnish women (aged 20-40 years) using total body dual energy x-ray absorptiometry (TB-DXA) as well as grip strength (GS [kPa]) with a hand-held dynamometer and knee extension strength (KES [kg]) between 2011 and 2014. Investigated body composition variables were appendicular skeletal mass (ASM [kg]), body mass index (BMI [kg/m2]), relative skeletal muscle index (RSMI [ASM/m2]), total lean mass (TLM [kg]), skeletal muscle index (SMI [TLM/weight × 100]) and fat-%. Participants filled out a questionnaire concerning life-style factors and habits: hormonal contraception, physical activity, alcohol consumption, age, pregnancies, smoking and self-assessed health that were also adjusting factors in the covariate model. We investigated the effects of hormonal contraception and other life-style factors and habits on body composition and muscle strength using AN(C)OVA in the analyses. RESULTS: Women using hormonal contraception with the combination of ethinyl estradiol + progestogen had significantly lower mean ASM (18.0), RSMI (6.5), TLM (40.8) (p < 0.01) and GS (34.6) (p < 0.001) compared to the women not using hormonal contraception with mean values of ASM (18.8), RSMI (6.7), TLM (42.6) and GS (36.9). After adjustment ASM (18.3), SMI (64.3), GS (35.2) (p < 0.05), RSMI (6.6) and TLM (41.2) (p < 0.01) were significantly lower and fat-% (31.4) higher (p < 0.05) compared to women not using hormonal contraception with mean values of ASM (19.0), SMI (66.1), GS (36.7), RSMI (6.8), TLM (42.7) and fat-% (29.8). CONCLUSION: Use of ethinyl estradiol + progestogen-containing hormonal contraception may have negative association with muscle mass and strength.

Personality disorder is an excess risk factor for physical multimorbidity among women with mental state disorders.

We examined whether mental state disorders (lifetime mood, anxiety, eating, substance misuse) with comorbid personality disorder are associated with physical multimorbidity in a population-based sample of women. Mental state and personality disorders were assessed using semi-structured diagnostic interviews. Clinical measures were performed and medical conditions, medication use and lifestyle factors were documented by questionnaire. Mental state disorders were associated with higher odds of physical multimorbidity; risk was especially high for those with comorbid personality disorder. These findings suggest that mental state and physical comorbidity might be worsened by the additional comorbidity of personality disorder.
