Normal values of balance tests in women aged 20-80

OBJECTIVES: To determine normal values for four commonly used clinical functional balance tests from community-dwelling women aged 20 to 80 and to identify any significant decline due to aging. DESIGN: A cross-sectional study was undertaken to provide normative values for four clinical balance tests across 6 decade cohorts. SETTING: The Betty Byrne-Henderson Center for Women and Aging, Royal Womens' Hospital, Brisbane, Australia. PARTICIPANTS: Four hundred fifty-six community-dwelling, independently ambulant women with no obvious neurological or musculoskeletal-related disability, aged 20 to 80, were randomly recruited from a large metropolitan region. MEASUREMENTS: The clinical balance measures/tests were the Timed Up and Go test, step test, Functional Reach test, and lateral reach test. Multivariate analysis was used to test the effect for age, height, and activity level. RESULTS: Normal data were produced for each test across each decade cohort. Gradual decline in balance performance was confirmed, with significant effect for age demonstrated. CONCLUSION: New normative data across the adult age decades are available for these clinical tests. Use of clinical balance tests could complement other balance tests and be used to screen women aged 40 to 60 whose performance is outside the normal values for age and to decrease later falls risk.

Physical therapy for urinary incontinence in postmenopausal women with osteoporosis or low bone density : a randomized controlled trial

Objective: To assess the effectiveness of 12 weekly physical therapy sessions for urinary incontinence (UI) compared with a control intervention, for reducing the number of UI episodes measured with the 7-day bladder diary, at 3 months and 1 year postrandomization. Methods: A single parallel-group randomized controlled trial was conducted at one outpatient public health center, in postmenopausal women aged 55 years and over with osteoporosis or low bone density and UI. Women were randomized to physical therapy (PT) for UI or osteoporosis education. The primary outcome measure was number of leakage episodes on the 7-day bladder diary, assessed at baseline, after treatment and at 1 year. The secondary outcome measures included the pad test and disease-specific quality of life and self-efficacy questionnaires assessed at the same timepoints. Results: Forty-eight women participated (24 per group). Two participants dropped out of each group and one participant was deceased before 3-month follow-up. Intention-to-treat analysis was undertaken. At 3 months and 1 year, there was a statistically significant difference in the number of leakage episodes on the 7-day bladder diary (3 mo: P = 0.04; 1 y: P = 0.01) in favor of the PT group. The effect size was 0.34 at 1 year. There were no harms reported. Conclusions: After a 12-week course of PT once per week for UI, PT group participants had a 75% reduction in weekly median number of leakage episodes, whereas the control group's condition had no improvement. At 1 year, the PT group participants maintained this improvement, whereas the control group's incontinence worsened.

L’expérience de vieillir au quotidien de femmes âgées montréalaises vivant seules à domicile dans un contexte de précarité économique

À ce jour, peu d’intérêt a été porté à l’exploration des expériences et réalités spécifiques au sous-groupe et sous-culture des femmes âgées vivant seules dans la pauvreté. Dans ce contexte, le but de cette étude était d’explorer et d’analyser l’expérience de vieillir au quotidien de femmes âgées montréalaises vivant seules à domicile dans un contexte de précarité économique. La théorie de l’universalité et de la diversité du soin de Madeleine Leininger a été l'assise théorique de cette étude et une approche qualitative avec devis de type mini-ethnographie a été retenue pour répondre au but de l’étude. Sept femmes âgées de 65 ans et plus, vivant seules à domicile dans un contexte de précarité économique, ont été recrutées pour participer à l’étude. Une approche «boule de neige» a été sélectionnée pour effectuer le recrutement des participantes qui s’est réalisé avec l’aide de deux ressources communautaires de Montréal. La collecte de données a été effectuée auprès de ces femmes par l’entremise d’entrevues individuelles semi-dirigées, d’un court questionnaire sociodémographique ainsi que par la tenue d'un journal de terrain. L’analyse qualitative de contenu s’est basée sur les quatre étapes du guide d'analyse des données de Leininger, soit : l'analyse des données brutes, le regroupement de celles-ci en patterns récurrents, l’émergence des sous-thèmes et thèmes ainsi que la formulation des résultats de recherche sous forme d’énoncés théoriques ou de recommandations. Les résultats de cette étude renseignent sur l’expérience de vieillir au quotidien de ces femmes par rapport à six facteurs culturels de leur structure sociale soit l’environnement, les valeurs culturelles, le mode de vie, les relations humaines, le facteur économique et l’ethnohistoire de même que par rapport à leur expérience de santé/maladie et vieillissement et à leur relation avec le système de soins. Les résultats en lien avec les facteurs culturels permettent de conclure que cette expérience de vieillir s’ancre principalement dans l’environnement intime du domicile de ces femmes, se concrétise en des sentiments de liberté, d’indépendance et de contrôle, s’enrichit dans le don de soi, se délimite à l’intérieur d’un réseau social appauvri et s’épanouit dans une vision positive de la vie et le refus d’un statut de pauvreté et de dépendance. Quant aux résultats relatifs aux dimensions de l’expérience humaine et du système de soins, ils révèlent que l’expérience de vieillir de ces femmes s’inscrit dans une volonté de préserver la fonctionnalité de leur corps, de conserver leur autonomie et de se positionner comme l’experte sur leur santé dans leur rapport avec les soins professionnels reçus. Les résultats révèlent aussi des indices de leur autodétermination, de leur résilience, de leur pouvoir d’agir et du sens qu’elles donnent à la vie dans les différents aspects de leur expérience de vieillir. Finalement, les résultats de la présente étude soutiennent des recommandations cliniques promouvant des approches de soins infirmiers culturellement cohérentes et empreintes d’empowerment auprès de ces femmes.

Redução da força muscular está relacionada à perda muscular em mulheres acima de 40 anos

O objetivo do estudo foi comparar a influência da idade na massa muscular e na força muscular, de membros superiores e inferiores, em mulheres acima de 40 anos. Foram estudadas 52 voluntárias, divididas em 3 grupos etários: 40-49 anos(G40, n=16), 50-59 anos(G50, n=18) e 60-70 anos(G60, n=18). Avaliaram-se: massa muscular (MM) por impedância bioelétrica e força muscular-1RM (FM). Para estatística, utilizaram-se análise variância-one-way, teste de Duncan e correlação de Pearson. Observou-se diferença significativa (p<0,05) entre 10,1% na MM entre G40 e G50 e 7,5% entre G50 e G60, totalizando 16,8% nas duas décadas (G40/G60). A FM de membros inferiores foi 16,4% menor entre G40 e G50 e 12,5% entre G50 e G60, perfazendo 25,3% nas duas décadas (p<0,05). Nos membros superiores, não houve diferença significativa da força, entre G40 e G50 (3,3% supino reto e 2,5% rosca direta) e entre G50 e G60 (17,5% e 9,6%), totalizando, nas duas décadas, 20,2% e 12,2%, respectivamente. A Soma das FMs foi corrigida pela MM (FMs/MM), não apresentando diferenças estatísticas entre os grupos. Correlacionando-se MM e FM, houve maior analogia nos membros inferiores (r=0,57), quando comparados aos membros superiores (r=0,42 e r=41, respectivamente). Concluíu-se que as mulheres apresentaram menores valores de MM e de FM nos membros inferiores logo na quinta década de vida. A FMs/MM parece não se alterar em mulheres entre 40 e 60 anos, quando comparadas por grupos etários. A MM reduzida parece ser fator importante para os menores valores de FM observados em mulheres entre 40 e 60 anos.

Prática de atividade física e composição corporal em mulheres na menopausa

OBJETIVO: Analisar a relação entre a prática de atividade física e composição corporal em mulheres na menopausa. METODOS: Participaram do estudo 62 mulheres, com 50 anos ou mais (61,2±7,6 anos), todas na menopausa. A prática de atividade física foi avaliada através do acelerômetro (minutos na semana e counts). A massa magra e massa gorda total e de tronco foram mensuradas com uso da absortimetria de raios X de dupla energia e expressas em valores percentuais. A relação entre as variáveis de composição corporal e a atividade física foi avaliada pela correlação de Spearman e de Pearson. As comparações entre grupos (de acordo com a prática de atividade física e idade) foram realizadas por meio do teste t independente e Mann-Whitney. RESULTADOS: O grupo de idade igual ou inferior a 59 anos apresentou maiores médias de atividade física total em counts (3.572.435 versus 2.843.840) e minutos por semana de atividade física moderada-vigorosa (273 minutos versus 156 minutos). As mulheres que acumularam 150 minutos ou mais de atividade física moderada-vigorosa apresentaram valores inferiores de massa gorda total (43,8 versus 47,2 kg/m²), valores superiores de massa corporal magra (53,8 versus 49,6 kg) e IMC reduzido (27,7 versus 30,46 kg/m²) quando comparadas àquelas com menos de 150 minutos de atividade física na semana. Apenas o tempo em atividades moderadas apresentou correlação negativa com o percentual de gordura total (r=-0,26, p<0,05); já atividade física total em counts correlacionou-se com o percentual de massa magra (r=0,30), percentual de gordura total (r=-0,32), gordura de tronco (r=-0,29), e IMC (r=-0,32), todas as correlações apresentaram significância estatística de p<0,05. CONCLUSÃO: Mulheres na menopausa com idade igual ou superior a 50 anos que apresentam minutos em atividades moderada e vigorosa, e counts de atividade física total superiores possuem níveis inferiores de massa gorda e superiores de massa magra.

Pelvic floor muscles training to reduce symptoms and signs of vulvovaginal atrophy : a case study

Objective: Vulvovaginal atrophy (VVA), caused by decreased levels of estrogen, is a common problem in aging women. Main symptoms of VVA are vaginal dryness and dyspareunia. First-line treatment consists of the application of local estrogen therapy (ET) or vaginal moisturizer. In some cases however, symptoms and signs persist despite those interventions. This case study describes a 77-year-old woman with severe VVA symptoms despite use of local ET and the addition of pelvic floor muscle (PFM) training to her treatment. Methods: A patient with stress urinary incontinence and VVA was referred to a randomized clinical trial on PFM training. On pretreatment evaluation while on local ET, she showed VVA symptoms on the ICIQ Vaginal Symptoms questionnaire and the ICIQ-Female Sexual Matters associated with lower urinary tract Symptoms questionnaire, and also showed VVA signs during the physical and dynamometric evaluation of the PFM. She was treated with a 12-week PFM training program. Results: The patient reported a reduction in vaginal dryness and dyspareunia symptoms, as well as a better quality of sexual life after 12 weeks of PFM training. On posttreatment physical evaluation, the PFMs' tone and elasticity were improved, although some other VVA signs remained unchanged. Conclusions: Pelvic floor muscle training may improve some VVA symptoms and signs in women taking local ET. Further study is needed to investigate and confirm the present case findings and to explore mechanisms of action of this intervention for VVA.

Modeling factors that influence exercise and dietary change among midlife Australian women: results from the Healthy Aging of Women Study

The objective of this study was to investigate the factors that influence midlife women to make positive exercise and dietary changes. In late 2005 questionnaires were mailed to 866 women aged 51–66 years from rural and urban locations in Queensland, Australia and participating in Stage 2 of the Healthy Aging of Women Study. The questionnaires sought data on socio-demographics, body mass index (BMI), chronic health conditions, self-efficacy, exercise and dietary behavior change since age 40, and health-related quality of life. Five hundred and sixty four (69%) were completed and returned by early 2006. Data analysis comprised descriptive and bivariate statistics and structural equation modeling. The results showed that midlife is a significant time for women to make positive health behavior changes. Approximately one-third of the sample (34.6%) indicated that they had increased their exercise and around 60% had made an effort to eat more healthily since age 40. Modeling showed self-efficacy to be important in making both exercise and dietary changes. Although education appeared to influence self-efficacy in relation to exercise change, this was not the case for dietary change. The study has application for programs promoting healthy aging among women, and implies that those with low education, high BMI and poor mental health may need considerable support to improve their lifestyles.

A longitudinal study of the relationship between lifestyle and mental health among midlife and older women in Australia : findings from the Healthy Aging of Women Study

We investigated the temporal relationship between lifestyle and mental health among 564 midlife women. The mental health measured included anxiety, depression, and mental well-being; the lifestyle measures included body mass index (BMI), exercise, smoking, alcohol use, and caffeine consumption. We found that BMI was positively related with mental well-being (r = .316, p = .009); smokers had lower mental well-being than nonsmokers (β = 6.725, p = .006), and noncaffeine drinkers had higher mental well-being (β = 5, p = .023). Past alcohol-drinkers had less anxiety than nondrinkers (β = 1.135, p = .04). Therefore, lifestyle is predictive of mental health among midlife and older women.

Predictors of mental health in post-menopausal women : results from the Australian healthy aging of women study

Objective: To examine the extent to which socio-demographics, modifiable lifestyle, and physical health status influence the mental health of post-menopausal Australian women. Methods: Cross-sectional data on health status, chronic disease and modifiable lifestyle factors were collected from a random cross-section of 340 women aged 60-70 years, residing in Queensland, Australia. Structural equation modelling (SEM) was used to measure the effect of a range of socio-demographic characteristics, modifiable lifestyle factors, and health markers (self-reported physical health, history of chronic illness) on the latent construct of mental health status. Mental health was evaluated using the Medical Outcomes Study Short Form 12 (SF-12®) which examined and Center for Epidemiologic Studies Depression Scale (CES-D). Results: The model was a good fit for the data (χ2=4.582, df=3, p=0.205) suggesting that mental health is negatively correlated with sleep disturbance (β = -0.612, p <0.001), and a history of depression (β = -0.141, p = 0.024).While mental health was associated with poor sleep, it was not correlated with most lifestyle factors (BMI, alcohol consumption, or cigarette smoking) or socio-demographics like age, income or employment category and they were removed from the final model. Conclusion: Research suggests that it is important to engage in a range of health promoting behaviours to preserve good health. We found that predictors of current mental health status included sleep disturbance, and past mental health problems, while socio-demographics and modifiable lifestyle had little impact. It may be however, that these factors influenced other variables associated with the mental health of post-menopausal women, and these relationships warrant further investigation.

Prevalence and correlates of sleep disturbance in post-menopausal Australian women : the Healthy Aging of Women (HOW) study

Background: Sleep disturbance in midlife women has been studied extensively, although less is known about sleep after menopause. This study examined the relative impact of socio-demographics, modifiable lifestyle factors, and health status on sleep disturbance in post-menopausal women from Queensland, Australia. Methods: The longitudinal Healthy Aging of Women (HOW) study examines health-related quality of life (HRQOL measured by SF-12©), chronic illness, modifiable lifestyle factors such as physical activity, alcohol consumption, smoking, and sleep disturbance (General Sleep Disturbance Scale, GSDS ≥ 43 represent poor sleep) in midlife and older women from low and high socio-economic, rural and urban areas of South-East Queensland, Australia. This paper presents cross-sectional data from the 322 women, aged 60-70 years, participating in the HOW study in 2011. Results: For women in this study, sleep disturbance was relatively common, with 23% (n = 83) reporting poor sleeping (GSDS ≥ 43). Sleep disturbance scores were strongly correlated with being unemployed or on a disability support pension (β = 18.69, P < 0.01), sedentary lifestyle (β = 23.84, P < 0.01), and lower mental (β = -0.60, P <0.01) and physical health-related quality of life scores (β = -0.32, P = 0.01), and these variables explained almost one third of variance in sleep disturbance scores (ηρ² = 29%). Conclusions: Multivariable analysis revealed that sleep disturbance was correlated with physical and mental health-related quality of life, disability, and sedentary lifestyle, but not other lifestyle and socio-demographic characteristics. It may be however, that modifiable lifestyle factors may indirectly impact on sleep by influencing health status.

A longitudinal study of the impact of chronic psychological stress on health-related quality of life and clinical biomarkers : protocol for the Australian Healthy Aging of Women Study

BACKGROUND: Despite advancements in our understanding of the importance of stress reduction in achieving good health, we still only have limited insight into the impact of stress on cellular function. Recent studies have suggested that exposure to prolonged psychological stress may alter an individual's physiological responses, and contribute to morbidity and mortality. This paper presents an overview of the study protocol we are using to examine the impact of life stressors on lifestyle factors, health-related quality of life and novel and established biomarkers of stress in midlife and older Australian women.The primary aim of this study is to explore the links between chronic psychological stress on both subjective and objective health markers in midlife and older Australian women. The study examines the extent to which exposure frightening, upsetting or stressful events such as natural disasters, illness or death of a relative, miscarriage and relationship conflict is correlated with a variety of objective and subjective health markers.Methods/design: This study is embedded within the longitudinal Healthy Aging of Women's study which has collected data from midlife and older Australian women at 5 yearly intervals since 2001, and uses the Allostastic model of women's health by Groer and colleagues in 2010. The current study expands the focus of the HOW study and will assess the impact of life stressors on quality of life and clinical biomarkers in midlife and older Australian women to explain the impact of chronic psychological stress in women. DISCUSSION: The proposed study hypothesizes that women are at increased risk of exposure to multiple or repeated stressors, some being unique to women, and the frequency and chronicity of stressors increases women's risk of adverse health outcomes. This study aims to further our understanding of the relationships between stressful life experiences, perceived quality of life, stress biomarkers, chronic illness, and health status in women.

Predictors of mental health in midlife and older women : results from the Australian Healthy Aging of Women Study

Purpose: To examine the extent to which socio-demographic characteristics, modifiable lifestyle factors and health status influence the mental health of midlife and older Australian women from the Australian Healthy Aging of Women (HOW) study. Methods: Data on health status, chronic disease and modifiable lifestyle factors were collected from a random sample of 340 women aged 40-65 years, residing in Queensland, Australia in 2011. Structural equation modelling (SEM) was used to measure the effect of a range of socio-demographic characteristics (marital status, age, income), modifiable lifestyle factors (caffeine intake, alcohol consumption, exercise, physical activity, sleep), and health markers (self-reported physical health, history of chronic illness) on the latent construct, mental health. Mental health was evaluated using the Medical Outcomes Study Short Form 12 (SF-12®) and the Center for Epidemiologic Studies Depression Scale (CES-D). Results: The model was a good fit for the data (χ2 = 40.166, df =312, p 0.125, CFI = 0.976, TLI = 0.950, RMSEA = 0.030, 90% CI = 0.000-0.053); the model suggested mental health was negatively influenced by sleep disturbance (β = -0.628), sedentary lifestyle (β = -0.137), having been diagnosed with one or more chronic illnesses (β = -0.203), and poor self-reported physical health (β = - 0.161). While mental health was associated with sleep, it was not correlated with many other lifestyle factors (BMI (β = -0.050), alcohol consumption (β = 0.079), or cigarette smoking (β = 0.008)) or background socio-demographic characteristics (age (β = 0.078), or income (β = -0.039)). Conclusion: While research suggests that it is important to engage in a range health promoting behaviours to preserve good health, we found that only sleep disturbance, physical health, chronic illness and level of physical activity predicted current mental health. However, while socio-demographic characteristics and modifiable lifestyle factors seemed to have little direct impact on mental health, they probably had an indirect effect.
