RESUMEN

Background: Nature therapy can significantly benefit the physiology and psychology of middle-aged and older people, but previous studies have focused on forest environments. The restoration potential of rural environments in urban fringe areas, which are more accessible to older people on a daily basis, has not been fully studied. This study assessed the effects of nature therapy on the physical and mental health of older women in a rural setting (locally known as Linpan) in the urban fringe area of Chengdu, China. Methods: We recruited a total of 60 older women (65.3 ± 5.5 years old) living in cities for 3 days of nature therapy in the winter (30 subjects) and spring (30 subjects), including 20 hypertensive patients. Results: The results showed that the overall blood pressure, pulse and sleep dysfunction rating scores of the participants were significantly lower than the pretest levels, and the finger blood oxygen saturation, mid-day salivary alpha-amylase and cortisol were increased post-treatment. Increases in these biomarker indicates and increase in stress. There were significant differences in the changes in systolic blood pressure between the hypertension group (HTN) and the normal group (normal) (HTN decreased by 8.8%, normal decreased by 5.4%), salivary alpha-amylase content (HTN decreased by 0.3%, normal increased by 16.9%), and sleep dysfunction rating scores (HTN decreased by 59.6%, normal decreased by 54%). The decreases in systolic blood pressure and pulse in the winter group were higher than those in the spring group by 1.8 and 4.4%, respectively, while the increases in salivary alpha-amylase content and salivary cortisol content were lower than those in the spring group by 11.7 and 11.2%, respectively, and the decrease in sleep dysfunction rating scores was lower than that in the spring group by 7.1%. Conclusion: Our study concluded that nature therapy based on various health activities in the Linpan has significant health effects on older women. It can regulate blood pressure and pulse in older women, relieve cardiovascular disease, improve sleep quality. Meanwhile, older women with high blood pressure experienced a more significant effect than the healthy group.

RESUMEN

The aim of the present study was to analyze the effects of a Qigong exercise programme on the severity of the menopausal symptoms and health-related quality of life (HRQoL) of community-dwelling postmenopausal women. This was done by means of a randomised clinical trial with a sample of 125 women who were assigned to either a control (n = 62) or an experimental group (n = 63). The severity of their menopause-related symptoms and HRQoL were assessed through the Menopause Rating Scale (MRS) and the 36-item Short-Form Health Survey (SF-36) respectively, before and after the intervention period. The main findings of our study reveal significant improvement in the severity of menopausal symptoms at the somatic, psychological, and urogenital levels, as well as in the total score of the MRS. Additionally, participants assigned to the Qigong group experienced improvement in the general health, physical functioning, role-physical, bodily pain, vitality, and mental health domains of the 36-item Short-Form Health Survey, as well as in its physical component and mental component summaries. We can therefore conclude that, among Spanish postmenopausal women, a twelve-week Qigong exercise programme has beneficial effects on the severity of menopausal symptoms and HRQoL.HighlightsWe have studied the effects of Qigong on menopause-related quality of life.Qigong is a useful tool in the management of the severity of menopausal symptoms.A 12-week Qigong programme showed benefits on health-related quality of life.Trial registration: ClinicalTrials.gov identifier: NCT03989453.

RESUMEN

BACKGROUND AND AIMS: We and others have identified links between cardiovascular conditions and poor musculoskeletal health. However, the relationship between measures of carotid atherosclerosis such as focal carotid plaque and common carotid intima media thickness (CCA-IMT) and falls remains understudied. This study examined the association between measures of carotid atherosclerosis and fall-related hospitalization over 11.5 years in community dwelling older women. METHODS AND RESULTS: 1116 older women recruited in 1998 to a five-year randomized controlled trial to examine the effect of calcium supplementation in preventing fracture and who had undertaken B-mode ultrasound in 2001 (three years after the baseline clinical visit) were included in this study. The participants were followed for over 11.5 years as Perth Longitudinal Study of Ageing Women (PLSAW). Over the follow up period, 428 (38.4%) women experienced a fall-related hospitalization. Older women with carotid plaque had 44% a higher relative hazard for fall-related hospitalization (HR 1.44; 95%CI, 1.18 to 1.76) compared to those without carotid plaque. The association persisted after adjustment for established falls risk factors such as measures of muscle strength and physical function.Each SD increase in the mean and maximum CCA-IMT was also associated with a higher risk of fall-related hospitalizations (HR 1.10; 95%CI, 1.00 to 1.21 and HR 1.11; 95%CI, 1.01 to 1.22, respectively). CONCLUSIONS: Measures of carotid atherosclerosis are associated with a higher risk of fall-related hospitalization independent of established falls risk factors. These findings suggest the importance of vascular health when considering falls risk.

RESUMEN

BACKGROUND: Research on the body image and eating behaviors of older women is scarce. Moreover, the scant existing research has lacked a focus on positive dimensions, such as positive reappraisal and acceptance, body appreciation, appearance satisfaction, and intuitive eating among older women. Therefore, the aim of the present study was to examine a model of the relationships among these positive dimensions and psychological functioning in older women. METHODS: A sample of 171 women aged 60-75 years were recruited through social media to respond to a survey assessing body image, eating behaviors, and psychological wellbeing. RESULTS: The final model was a good fit to the data. In this model, positive reappraisal and acceptance of age-related appearance changes was associated with higher body appreciation, in turn associated with higher body image related quality of life, higher levels of intuitive eating, and lower levels of depressive symptoms. CONCLUSION: Positive body image and positive reappraisal of aging-related changes in appearance are associated with psychological wellbeing among older women. Longitudinal data are needed to clarify the direction of these relationships and inform interventions. Body image remains an important dimension among older women and should be accounted for in broader health promotion efforts among this group.

RESUMEN

Hatha yoga (HY) and aerobic and strengthening exercise (ASE) programs are recommended for optimal management of osteoarthritis. However, evidence on long-term adherence to these programs and factors that influence it is lacking in older adults. The purposes of this study were to (1) describe and compare long-term HY and ASE adherence in community-dwelling older women with knee osteoarthritis 12 months post-HY/ASE intervention programs; (2) identify benefits and facilitators of, and barriers to, long-term adherence; and (3) examine other self-care interventions used after completing HY or ASE programs. Adherence was defined as following the prescribed HY/ASE program or incorporating the practice into daily habits. Five semistructured focus group interviews and 12 months of exercise diaries were obtained from 28 women (mean age 71.2 years). Long-term adherence to the prescribed HY or ASE regimen was relatively high, albeit adapted to individual needs, priorities, and preferences. Over the 12-month follow-up period, participants spent on average 3.5 days/3.1 hours per week on exercise. Most participants remained physically active by modifying their prescribed programs and integrating elements of the interventions into their own exercise regimens. Facilitators to long-term adherence were perceived benefits, having an exercise routine/habit, and program structure/instruction. Poor health status, lack of time, and exercise preferences were identified as barriers. Participants used a variety of self-care interventions including oral supplements and alternative diets for managing their osteoarthritis. This work suggests that exercise programs for osteoarthritis that incorporate individual preferences, flexible hours, and easy-to-follow instructions are most likely to result in long-term adherence.

RESUMEN

BACKGROUND: The number of older women living with HIV in Africa is growing, and their health outcomes may be adversely impacted by social frailty, which reflects deficits in social resources that accumulate over the lifespan. Our objective was to adapt a Social Vulnerability Index (SVI) originally developed in Canada for use in a study of older women living with or without HIV infection in Mombasa, Kenya. METHODS: We adapted the SVI using a five-step process: formative qualitative work, translation into Kiswahili, a Delphi procedure, exploration of potential SVI items in qualitative work, and a rating and ranking exercise. Four focus group discussions (FGD) were conducted (three with women living with HIV and one with HIV-negative women), and two expert panels were constituted for this process. RESULTS: Themes that emerged in the qualitative work were physical impairment with aging, decreased family support, a turn to religion and social groups, lack of a financial safety net, mixed support from healthcare providers, and stigma as an added burden for women living with HIV. Based on the formative FGD, the expert panel expanded the original 19-item SVI to include 34 items. The exploratory FGD and rating and ranking exercise led to a final 16-item Kenyan version of the SVI (SVI-Kenya) with six domains: physical safety, support from family, group participation, instrumental support, emotional support, and financial security. CONCLUSIONS: The SVI-Kenya is a holistic index to measure social frailty among older women in Kenya, incorporating questions in multiple domains. Further research is needed to validate this adapted instrument.

RESUMEN

Background Polypharmacy is an important consideration for the provision of Residential Medication Management Reviews (RMMRs) among older women given their enhanced risk of medication-related problems and admission to residential aged care (RAC). Objectives To determine the prevalence of the use of RMMRs among older women in RAC, and the association between RMMRs and polypharmacy, medications, and costs. Setting Older Australian women aged 79-84 years in 2005 who had at least one Medicare Benefits Schedule and Pharmaceutical Benefits Scheme record, received a service in aged care, and consented to data linkage. Methods Generalised estimating equations were used to determine the association between polypharmacy and RMMRs, while adjusting for confounding variables. Main outcome measures Prevalence of the use of RMMRs among older women in RAC, association between RMMRs and polypharmacy, medications, and costs. Results Most participants did not have continuous polypharmacy and did not receive RMMRs from 2005 [451 (67.4%)] until 2017 [666 (66.6%)]. Participants with continuous polypharmacy were 17% more likely to receive a RMMR (risk ratio 1.17; 95% confidence interval 1.11, 1.25). Participants in their final year of life and residing in outer regional/remote/very remote Australia were less likely to receive RMMRs. Out-of-pocket medication costs increased over time, and alendronate and aspirin were common contributors to polypharmacy among participants who received RMMRs. Conclusion Polypharmacy was associated with receiving RMMRs and around two-thirds of women who are entitled to a RMMR never received one. There is potential to improve the use of medicines by increasing awareness of the service among eligible individuals, their carers and health care professionals.

RESUMEN

BACKGROUND: Exercise training above a given intensity is necessary to prevent age-associated physical disability and diseases; however, the physical and psychological barriers posed by deteriorated physical fitness due to aging may hinder older people from performing daily exercise training. Because 5-aminolevulinic acid (ALA), a precursor of heme, reportedly improves mitochondrial function, we examined whether ALA, combined with sodium ferrous citrate (SFC) for enhancement, improved aerobic capacity and voluntary exercise training achievement in older women aged over 75 yrs. METHODS: The study was conducted using a placebo-controlled, double-blind crossover design. Fifteen women aged ~78 yrs. with no exercise habits underwent two trials for 7 days each where they performed interval walking training (IWT), repeating fast and slow speeds of walking for 3 min each, at >70% and at ~40% of peak aerobic capacity for walking, respectively, with ALA+SFC (100 and 115 mg/day, respectively) or placebo supplement intake (CNT), with a 12-day washout period. Before and after each trial, subjects underwent a graded cycling test while having their oxygen consumption rate (V·O2), carbon dioxide production rate (V·CO2), and plasma lactate concentration ([Lac-]p) measured. Furthermore, during the supplement intake period, exercise intensity for IWT was measured by accelerometry. RESULTS: In ALA+SFC, the increases in V·O2 and V·CO2 during the graded cycling test were attenuated (both, P < 0.01) with a 13% reduction in [Lac-]p (P = 0.012) while none of these attenuated responses occurred in CNT (all, P > 0.46). Furthermore, energy expenditure and time during fast walking for IWT were 25% (P = 0.032) and 21% (P = 0.022) higher in ALA+SFC than in CNT. CONCLUSION: Thus, ALA+SFC supplementation improved aerobic capacity and thus increased fast-walking training achievement in older women.

RESUMEN

BACKGROUND: The National Comprehensive Cancer Network Breast Cancer Guidelines Committee suggests that the omission of adjuvant radiation therapy (RT) after breast-conserving surgery can be a reasonable option among older women with low-risk breast cancer (early-stage, estrogen receptor-positive, and node-negative) if they are treated with endocrine therapy. However, RT usage in this group of women still exceeds 50%. Conversely, older women tend to forego RT (even when necessary) due to cost, inconvenience, and potential adverse responses associated with RT. Understanding health-related quality of life (HRQOL) change with receipt of RT among older women in the modern era is limited due to the under-representation of this population in clinical trials. OBJECTIVE: The proposed study aims to examine the associations of RT with HRQOL trajectories as well as survival outcomes among older women with 5-10 years of follow-up. We will also assess whether prediagnosis comorbidity burden influences receipt of RT and whether the associations between RT and HRQOL trajectory and survival outcomes are modified by the comorbidity burden. METHODS: We will use a retrospective cohort study design with the population-based Surveillance, Epidemiology, and End-Results database linked to the Medicare Health Outcomes Survey (SEER-MHOS). Older women (≥65 years) who were diagnosed with low-risk breast cancer in 1998-2014, received breast-conserving surgery, and participated in MHOS 1998-2016 are eligible for this analysis. The latent class analysis clustering method will be used to identify each patient's prediagnosis comorbidity burden, and HRQOL will be evaluated using the Short Form 36/Veterans RAND 12-Item Health Survey scales. The inverse-weighted estimates of the probability of treatment will be included to control for treatment selection bias and confounding effects in subsequent analysis. The association of RT with HRQOL trajectory will be evaluated using inverse-weighted multilevel growth mixture models. The inverse-weighted Cox regression model will be used to obtain hazard ratios with 95% CIs for the association of RT with survival outcomes. Differential effects of RT on both outcomes according to comorbidity burden class will also be evaluated. RESULTS: As of October 2020, the study was approved by the institutional review board, and SEER-MHOS data were obtained from the National Cancer Institute. Women with low-risk breast cancer who met inclusion and exclusion criteria have been identified, and prediagnosis comorbidity burden class has been characterized using latent class analysis. Further data analysis will begin in November 2020, and the first manuscript will be submitted in a peer-reviewed journal in February 2021. CONCLUSIONS: This research can potentially improve clinical outcomes of older women with low-risk breast cancer by providing them additional information on the HRQOL trajectories when they make RT treatment decisions. It will facilitate informed, shared treatment decision making and cancer care planning to ultimately improve the HRQOL of older women with breast cancer.

RESUMEN

BACKGROUND: A significant proportion of older women suffer from chronic pain, which can decrease quality of life. The objective of this pilot randomized study was to evaluate the feasibility of a flow-restorative yoga intervention designed to decrease pain and related outcomes among women aged 60 or older. METHODS: Flow-restorative yoga classes were held twice weekly for 1 hour and led by a certified yoga instructor. Participants randomized to the intervention group attended the yoga classes for 12 weeks and received supplemental materials for at-home practice. Those randomized to the control group were asked to maintain their normal daily routine. Feasibility was evaluated using recruitment and retention rates, class and home practice adherence rates, and participant satisfaction surveys. Outcome measures (self-reported pain, inflammatory markers, functional fitness, quality of life, resilience, and self-reported physical activity) were assessed at baseline and post-intervention. Paired t-tests or Wilcoxon signed-rank tests were used to examine changes in outcome measures within treatment groups. RESULTS: Thirty-eight participants were recruited and randomized. Participants were primarily white, college-educated, and higher functioning, despite experiencing various forms of chronic pain. Attendance and retention rates were high (91 and 97%, respectively) and the majority of participants were satisfied with the yoga program (89%) and would recommend it to others (87%). Intervention participants also experienced reductions in pain interference and improvements in energy and social functioning. CONCLUSIONS: This pilot study provides essential data to inform a full scale randomized trial of flow-restorative yoga for older women with chronic pain. Future studies should emphasize strategies to recruit a more diverse study population, particularly older women at higher risk of disability and functional decline.

RESUMEN

BACKGROUND: Aging appears to attenuate the response of skeletal muscle protein synthesis (MPS) to anabolic stimuli such as protein ingestion (and the ensuing hyperaminoacidemia) and resistance exercise (RE). OBJECTIVES: The purpose of this study was to determine the effects of protein quality on feeding- and feeding plus RE-induced increases of acute and longer-term MPS after ingestion of whey protein (WP) and collagen protein (CP). METHODS: In a double-blind parallel-group design, 22 healthy older women (mean ± SD age: 69 ± 3 y, n = 11/group) were randomly assigned to consume a 30-g supplement of either WP or CP twice daily for 6 d. Participants performed unilateral RE twice during the 6-d period to determine the acute (via [13C6]-phenylalanine infusion) and longer-term (ingestion of deuterated water) MPS responses, the primary outcome measures. RESULTS: Acutely, WP increased MPS by a mean ± SD 0.017 ± 0.008%/h in the feeding-only leg (Rest) and 0.032 ± 0.012%/h in the feeding plus exercise leg (Exercise) (both P < 0.01), whereas CP increased MPS only in Exercise (0.012 ± 0.013%/h) (P < 0.01) and MPS was greater in WP than CP in both the Rest and Exercise legs (P = 0.02). Longer-term MPS increased by 0.063 ± 0.059%/d in Rest and 0.173 ± 0.104%/d in Exercise (P < 0.0001) with WP; however, MPS was not significantly elevated above baseline in Rest (0.011 ± 0.042%/d) or Exercise (0.020 ± 0.034%/d) with CP. Longer-term MPS was greater in WP than in CP in both Rest and Exercise (P < 0.001). CONCLUSIONS: Supplementation with WP elicited greater increases in both acute and longer-term MPS than CP supplementation, which is suggestive that WP is a more effective supplement to support skeletal muscle retention in older women than CP.This trial was registered at clinicaltrials.gov as NCT03281434.

RESUMEN

BACKGROUND: The results obtained from previous trials regarding the effects of vitamin D supplementation on muscle strength and mobility in postmenopausal women have been inconsistent. This systematic review and meta-analysis of randomised controlled trials (RCTs) aimed to investigate the effect of vitamin D supplementation on muscle strength and mobility in postmenopausal women. METHODS: A comprehensive search on EMBASE, PubMed, MEDLINE and SCOPUS was performed to identify relevant articles published up to 28 March 2019. RCTs published in English measuring the effect of all forms and doses of vitamin D supplementation with or without calcium on muscle strength and mobility outcomes in postmenopausal women were included. RESULTS: In total, 29 eligible studies were included in the systematic review. The pooled findings using a random effects model showed that vitamin D supplementation insignificantly increased hand grip strength (HGS) as the measurement of muscle strength (MD = 0.656; 95% confidence interval = -0.037 to 1.350, P = 0.06). However, it did not affect timed-up-and-go (TUG) as the measurement of mobility (MD = 0.118; 95% confidence interval = -0.655 to 0.892, P = 0.76). The subgroup analyses showed that vitamin D supplementation improved HGS with respect to dosages >1000 IU day-1 (P = 0.016), a treatment duration of 3 months (P Ë‚ 0.001) and subjects with baseline vitamin D <30 ng mL-1 (P = 0.033). CONCLUSIONS: The present review demonstrates that vitamin D supplementation resulted in small but nonsignificant improvements in muscle strength compared to control in postmenopausal women. No significant effect was observed in mobility after vitamin D administration.

RESUMEN

The vitamin D debate relates in part to ideal public health population levels of circulating 25-hydroxyvitamin D (25OHD) to maintain bone structure and reduce fracture. In a secondary analysis of 1348 women aged 70 to 85 years at baseline (1998) from the Perth Longitudinal Study of Aging in Women (a 5-year calcium supplementation trial followed by two 5-year extensions), we examined the dose-response relations of baseline plasma 25OHD with hip DXA BMD at year 1, lumbar spine BMD, and trabecular bone score (TBS) at year 5, and fracture-related hospitalizations over 14.5 years obtained by health record linkage. Mean baseline plasma 25OHD was 66.9 ± 28.2 nmol/L and 28.5%, 36.4%, and 35.1% of women had levels <50, 50 to 74.9, and ≥75 nmol/L, respectively. Generalized additive models showed that total hip and femoral neck BMD and TBS, but not spine BMD, were higher with increasing plasma 25OHD up to 100 nmol/L. Compared with those with 25OHD <50 nmol/L, women with 25OHD ≥75 nmol/L had significantly higher total hip and femoral neck BMD at year 1 (3.3% to 3.9%) and TBS at year 5 (2.0%), all P < 0.05. During the follow-up, 27.6% of women experienced any fracture-related hospitalization and 10.6% hip fracture-related hospitalization. Penalized spline regression models showed a decrease in risk with increased 25OHD levels up to 65 nmol/L and 75 nmol/L for hip fracture and any fracture-related hospitalization, respectively. Cox regression grouped analyses showed that compared with women with 25OHD <50 nmol/L, those with 25OHD levels 50 to 74.9 and ≥75 nmol/L had significantly lower risk for hip fracture [HR 0.60 (95% CI, 0.40 to 0.91) and 0.61 (95% CI, 0.40 to 0.92), respectively], and any fracture-related hospitalization [HR 0.77 (95% CI, 0.59 to 0.99) and 0.70 (95% CI, 0.54 to 0.91), respectively]. In older white women, 25OHD levels >50 nmol/L are a minimum public health target and 25OHD levels beyond 75 nmol/L may not have additional benefit to reduce fracture risk. © 2019 American Society for Bone and Mineral Research.

RESUMEN

BACKGROUND: Frailty is a clinical condition associated with loss of muscle mass and strength (sarcopenia). Although sarcopenia has multifactorial causes, it might be partly attributed to a blunted response to anabolic stimuli. Leucine acutely increases muscle protein synthesis, and resistance training (RT) is the strongest stimuli to counteract sarcopenia and was recently shown to improve insulin sensitivity (IS) in frail older women. Discrepancies exist regarding whether chronic supplementation of leucine in conjunction with RT can improve muscle mass and IS. OBJECTIVE: The aim of this double-blinded placebo-controlled study was to determine the effects of leucine supplementation and RT on IS in prefrail and frail older women. METHODS: Using the Fried criteria, 19 nondiabetic prefrail (1-2 criteria) and frail (≥3 criteria) older women (77.5 ± 1.3 y; body mass index (kg/m2): 25.1 ± 0.9) underwent a 3-mo intervention of RT 3 times/wk with protein-optimized diet of 1.2 g·kg-1·d-1 and 7.5 g·d-1 of l-leucine supplementation compared with placebo l-alanine. Pre-/postintervention primary outcomes were fasting plasma glucose, serum insulin, and 4-h responses to a standard meal of complete liquid formula. Secondary outcomes of resting energy expenditure using indirect calorimetry and body composition using dual-energy X-ray absorptiometry were obtained. Paired t tests analyzed pooled data, and 2-factor repeated-measures ANOVA determined supplementation, training, and interaction effects. RESULTS: No significant time, group, or interaction effects were observed for postprandial areas under the curve of serum insulin or plasma glucose or for resting energy expenditure in l-leucine compared with l-alanine. Total lean body mass increased and percentage body fat decreased significantly for both groups postintervention (0.76 ± 0.13 and -0.92 ± 0.33 kg, respectively; time effect: P < 0.01). CONCLUSIONS: IS was not affected by RT and leucine supplementation in nondiabetic prefrail and frail older women. Therefore, leucine supplementation does not appear to influence IS under these conditions. This trial was registered at clinicaltrials.gov as NCT01922167.

RESUMEN

BACKGROUND: Previous research indicates that dance training may improve balance among older adults. AIMS: This study investigated the effects of Thai traditional dance on balance performance among older women. METHODS: Forty-three women aged 60-80 years, with mean scores between 45 and 52 points on the Berg Balance Scale (BBS), were recruited and randomly assigned into two groups: a Thai traditional dance group (TTDG) (n = 22) and a control group (CG) (n = 21). TTD program comprised three dance sessions of 30-60 min per week over the course of 12 weeks while the CG kept their normal daily activities. Balance performance was assessed using standardized tests including the NeuroCom Balance Master® System (Version 9.2), the Timed Up and Go Test (TUG) and the BBS. RESULTS: The results revealed that overall balance was better for those in TTDG compared to the CG. There was a significantly lower sway velocity and faster weight transfer in the Sit-to-Stand Test (p ≤ 0.001) for those in the dance group. TTDG had quicker turn time in the Step Quick Turn Test (p ≤ 0.001), improved Step Up Over Test and Walk Across Test, faster movement time, walking speed, and a better score in the TUG after training (p ≤ 0.001). DISCUSSION: A 3-weekly Thai traditional dance intervention significantly improved balance and mobility among older community-dwelling women as compared to normal daily activities. CONCLUSION: Thai traditional dance could potentially prevent age-related mobility and balance decline and its related fall risk.

RESUMEN

Three hundred eighty-seven home-dwelling older women were divided into quartiles based on mean serum 25-hydroxyvitamin D (S-25(OH)D) levels. The rates of falls and fallers were about 40% lower in the highest S-25(OH)D quartile compared to the lowest despite no differences in physical functioning, suggesting that S-25(OH)D levels may modulate individual fall risk. INTRODUCTION: Vitamin D supplementation of 800 IU did not reduce falls in our previous 2-year vitamin D and exercise RCT in 70-80 year old women. Given large individual variation in individual responses, we assessed here effects of S-25(OH)D levels on fall incidence. METHODS: Irrespective of original group allocation, data from 387 women were explored in quartiles by mean S-25(OH)D levels over 6-24 months; means (SD) were 59.3 (7.2), 74.5 (3.3), 85.7 (3.5), and 105.3 (10.9) nmol/L. Falls were recorded monthly with diaries. Physical functioning and bone density were assessed annually. Negative binomial regression was used to assess incidence rate ratios (IRRs) for falls and Cox-regression to assess hazard ratios (HR) for fallers. Generalized linear models were used to test between-quartile differences in physical functioning and bone density with the lowest quartile as reference. RESULTS: There were 37% fewer falls in the highest quartile, while the two middle quartiles did not differ from reference. The respective IRRs (95% CI) for falls were 0.63 (0.44 to 0.90), 0.78 (0.55 to 1.10), and 0.87 (0.62 to 1.22), indicating lower falls incidence with increasing mean S-25(OH)D levels. There were 42% fewer fallers (HR 0.58; 040 to 0.83) in the highest quartile compared to reference. Physical functioning did not differ between quartiles. CONCLUSIONS: Falls and faller rates were about 40% lower in the highest S-25(OH)D quartile despite similar physical functioning in all quartiles. Prevalent S-25(OH)D levels may influence individual fall risk. Individual responses to vitamin D treatment should be considered in falls prevention.

RESUMEN

Objective: To examine U.S. Chinese older women and the association between their cancer screening behaviors and self-reported cancers with Traditional Chinese Medicine (TCM) use across sociodemographic characteristics. Method: Through the Population Study of Chinese Elderly in Chicago (PINE), 1,830 Chinese older women self-reported history of cancer screening, presence of women's cancers, and TCM use according to type. Analyses were performed using multivariate regression models. Results: Chinese older women who underwent breast cancer screening are more likely to use herbal TCM (rate ratio [RR] = 1.15, 95% confidence interval [CI] = [1.03, 1.29]), acupuncture (RR = 1.62, CI = [1.21, 2.15]), massage therapy (RR = 2.05, CI = [1.46, 2.88]), and tai chi (RR = 1.86, CI = [1.28, 2.69]). Those who had cervical cancer screening are more likely to use herbal TCM (RR = 1.32, CI = [1.17, 1.48]), acupuncture (RR = 1.66, CI = [1.27, 2.18]), massage therapy (RR = 1.61, CI = [1.17, 2.21]), tai chi (RR = 1.69, CI = [1.19, 2.40]), and other forms of TCM (RR = 1.36, CI = [1.04, 1.79]). Those with cervical cancer are less likely to use herbal TCM (RR = 0.42, CI = [0.19, 0.93]). Conclusion: Contrary to previous studies, our results suggest that U.S. Chinese older women who have engaged in cancer screening use TCM while those with self-reported cancer did not use TCM at a higher rate. This warrants further research on TCM utilization to identify reasons of use in this population and encourage patient-centered care.

RESUMEN

The objective of the study was to determine the association between AAC and neuromuscular function over 5 years. Participants in this study were ambulant women over 70 years old residing in Perth, Western Australia who participated in the Calcium Intake Fracture Outcomes Study, a randomised controlled trial of calcium supplementation. 1046 women (mean age = 74.9 ± 2.6 years; BMI = 27.1 ± 4.4 kg/m2) were included. Lateral spine images captured during bone density testing were scored for AAC (AAC24; 0-24) at baseline. Severe AAC (AACsev) was defined using established cut points (AAC24 ≥ 6). At baseline and follow-up, isometric grip strength was assessed using a dynamometer. Mobility was assessed by the Timed-Up-and-Go (TUG) test. Using pre-defined criteria, muscle weakness was considered as grip strength < 22 kg and poor mobility defined as TUG > 10.2 s. A subset of women had appendicular lean mass (ALM) determined by dual-energy X-ray absorptiometry at baseline and follow-up (n = 261). AACsev was evident in 193 (18.5%) women. Average decline in grip strength after 5 years was greater in those with AACsev than those without (3.6 ± 3.7 vs. 2.9 ± 4.2 kg; p = 0.034). This remained significant after adjustment for age, treatment allocation, diabetes, smoking history, renal function, medical record-derived prevalent vascular disease, BMI and physical activity (ß = - 0.184; 95% confidence interval: - 0.361, - 0.008; p = 0.040). AACsev was not associated with 5-year changes in TUG or ALM in univariable or multivariable analyses (all p > 0.05). In older women, severe aortic calcification was associated with greater 5-year decline in muscle strength, but not TUG or ALM. These findings support the concept that vascular disease may have an effect on the loss of muscular strength.

RESUMEN

OBJECTIVE: To clarify the effect of programmed exercise (PE), performed for at least six weeks, on perceived stress (PS) in middle aged and old women. METHODS: A structured search was carried out in PubMed, Embase, Cochrane Library, Scielo, Web of Science and Scopus, from database inception through January 10, 2018, without language restriction. The US, UK, and Australian clinical trials databases were also searched. The search included a combination of the terms "programmed exercise", "perceived stress", "menopausal women" and "randomized controlled trial" (RCTs). PE was classified according to duration as "mid-term exercise intervention" (MTEI; mean duration 6 months), and "long-term exercise intervention" (LTEI; mean duration 12 months). Mean ±â€¯standard deviations of changes in PS scores, as assessed with different questionnaires, were calculated as standardized mean differences (SMDs) and used as effect size for meta-analysis. SMDs of PS after intervention were pooled using a random-effects model. Study quality and bias risk were assessed with the Cochrane tool. RESULTS: Five RCTs that studied midlife and older women (mean age 47.0 ±â€¯1.7 years minimum to 71.8 ±â€¯5.6 maximum) were included in the meta-analysis. There was no significant effect of PE on PS score (SMD: -0.16; 95% CI: -0.43 to 0.11). In subgroup analyses, there was no significant effect of PE on PS with mid-term interventions (SMD: - 0.17; 95% CI: -0.59 to 0.25) nor with long-term interventions (SMD: -0.02; 95% CI: -0.42 to 0.38) as compared with controls. CONCLUSION: PE of low to moderate intensity does not improve PS in midlife and older women.

RESUMEN

BACKGROUND: Women with refractory urgency urinary incontinence (ie, unresponsive to behavioral and pharmacological interventions) are treated with onabotulinumtoxinA or sacral neuromodulation. OBJECTIVE: The objective of the study was to compare treatment efficacy and adverse events in women <65 and ≥65 years old treated with onabotulinumtoxinA or sacral neuromodulation. STUDY DESIGN: This study was a planned secondary analysis of a multicenter, randomized trial that enrolled community-dwelling women with refractory urgency urinary incontinence to onabotulinumtoxinA or sacral neuromodulation treatments. The primary outcome was a change in mean daily urgency urinary incontinence episodes on a bladder diary over 6 months. Secondary outcomes included ≥75% urgency urinary incontinence episode reduction, change in symptom severity/quality of life, treatment satisfaction, and treatment-related adverse events. RESULTS: Both age groups experienced improvement in mean urgency urinary incontinence episodes per day following each treatment. There was no evidence that mean daily urgency urinary incontinence episode reduction differed between age groups for onabotulinumtoxinA (adjusted coefficient, -0.127, 95% confidence interval, -1.233 to 0.979; P = .821) or sacral neuromodulation (adjusted coefficient, -0.698, 95% confidence interval, -1.832 to 0.437; P = .227). Among those treated with onabotulinumtoxinA, women <65 years had 3.3-fold greater odds of ≥75% resolution than women ≥65 years (95% confidence interval, 1.56 -7.02). Women <65 years had a greater reduction in Overactive Bladder Questionnaire Short Form symptom bother scores compared with women ≥65 years by 7.49 points (95% confidence interval, -3.23 to -11.74), regardless of treatment group. There was no difference between quality of life improvement by age. Women ≥65 years had more urinary tract infections following onabotulinumtoxinA and sacral neuromodulation (odds ratio, 1.9, 95% confidence interval, 1.2-3.3). There was no evidence of age differences in sacral neuromodulation revision/removal or catheterization following onabotulinumtoxinA treatment. CONCLUSION: Younger women experienced greater absolute continence, symptom improvement, and fewer urinary tract infections; both older and younger women had beneficial urgency urinary incontinence episode reduction, similar rates of other treatment adverse events, and improved quality of life.
