Older women`s experiences with sternotomy

While incision and subsequent scarring is a feature of all surgery, in cardiac surgery the sternotomy incision is significant and central to the body, separating the chest in half between the breasts. Increasingly older women count for a larger proportion of patients undergoing cardiac surgery each year in Australia yet there has been limited exploration of their experiences with sternotomy. A phenomenological approach was used to elicit the experiences of older women who had undergone cardiac surgery. In-depth interviews with four older women revealed a range of ways in which these women were affected by their sternotomy and their whole experience of cardiac surgery. Findings from this project provide insight into practical issues affecting these women and may assist nurses in the assessment and planning of care and education for older women having cardiac surgery, particularly in the areas of preparation for cardiac surgery and body image.

Fit for life : older women`s commitment to exercise

The article explores the lived experiences of older women with a high commitment to exercise. The methods of investigation were in-depth interviews with 17 women fitness instructors for the over-50s and the author's observations as a participant in a variety of exercise programs. The subjective experience of embodiment of older women, the ways in which the body is constructed discursively, and the objective processes of aging are explored. The women's narratives are placed in the wider context of consumption, lifestyle, and identity construction. The study analyzes whether older women's commitment to exercise is a reflection of a climate of constraint, in which individuals seek to shape and manage the body to combat the effects of aging, or is one of empowerment and enablement. More important, the article explores the ways in which the women used fitness programs as a means of constructing intimacy, a sense of community, and satisfaction in interpersonal relations.

Which aspects of socio-economic status are related to health in mid-aged and older women?

A population-based study was conducted to validate gender- and age-specific indexes of socio-economic status (SES) and to investigate the associations between these indexes and a range of health outcomes in 2 age cohorts of women. Data from 11,637 women aged 45 to 50 and 9,510 women aged 70 to 75 were analyzed. Confirmatory factor analysis produced four domains of SES among the mid-aged cohort (employment, family unit, education, and migration) and four domains among the older cohort (family unit, income, education, and migration). Overall, the results supported the factor structures derived from another population-based study (Australian Bureau of Statistics, 1995), reinforcing the argument that SES domains differ across age groups. In general, the findings also supported the hypotheses that women with low SES would have poorer health outcomes than higher SES women, and that the magnitude of these effects would differ according to the specific SES domain and by age group, with fewer and smaller differences observed among older women. The main exception was that in the older cohort, the education domain was significantly associated with specific health conditions. Results suggest that relations between SES and health are highly complex and vary by age, SES domain, and the health outcome under study.

Serum vitamin D and falls in older women in residential care in Australia

Objectives: To determine the prevalence of vitamin D deficiency in older people in residential care and the influence that the level of vitamin D may have on their incidence of falls.

Design: Prospective cohort.

Setting: Residential care facilities for older people in several states of Australia.

Participants: Six hundred sixty-seven women in low-level care and 952 women in high-level care, mean age 83.7 years.

Measurements: Serum 25-hydroxyvitamin D (25D) levels and recognized risk factors for falls including current medication use, a history of previous fractures, weight, tibial length (as a surrogate for height), cognitive function, walking ability, and frequency of going outdoors were determined. The women in low-level care and high-level care were followed for an average of 145 and 168 days, respectively. Falls were recorded prospectively in diaries completed monthly by residential care staff.

Results: Vitamin D deficiency (defined as a serum 25D level below 25 nmol/L) was present in 144 (22%) women in low-level care and 428 (45%) in high-level care. After excluding 358 bed-bound residents and adjusting for weight, cognitive status, psychotropic drug use, previous Colles fracture, and the presence of wandering behavior, log serum 25D level remained independently associated with time to first fall. The adjusted hazards ratio was 0.74 (95% confidence interval=0.59–0.94; P=.01), implying a 20% reduction in the risk of falling with a doubling of the vitamin D level.

Conclusion: Vitamin D deficiency is common in residential care in Australia. A low level of serum vitamin D is an independent predictor of incident falls.

Craft groups : sites of friendship, empowerment, belonging and learning for older women

This article reports on a qualitative research project conducted in Victoria, Australia, with nine older women. The purpose of the research was to explore the women's experience of involvement in craft groups, and specifically, the impact of this involvement on their sense of well-being. Traditionally the health of older people has been examined in relation to medical markers of physical well-being, and often, decline. We were interested to widen this perspective to understand the impact of social connection, belonging and ongoing learning and development on the ageing experience. While the focus of the groups was on domestic craftwork, the process of coming together as a collective appeared to have significant bearing on the holistic health of the women involved. Consistent with feminist groupwork literature, the findings indicated that the women we interviewed experienced the group setting as affirming and generative in a number of ways. These include providing an avenue for mutual aid, addressing isolation, affirming individual and collective strength and wisdom, while acquiring new skills, and normalising concerns regarding health and family.

Does the inclusion of moderate amounts of red meat in the diet of exercising older women impact on faecal markers of bowel health, including faecal lactoferrin?

Background: High intakes of red meat may be associated with increased risk of colorectal cancer (CRC), however, to determine CRC risk, it is important to assess faecal changes related to protein and carbohydrate metabolism.

Objective: To determine the influence of three weekly meals rich in red meat as opposed to a carbohydrate control diet on faecal markers which are involved in the aetiology of CRC.

Design: Twenty post-menopausal women (aged 60-75) undertook, 3 times a week for 12 weeks, a 30 minute exercise session followed immediately by a cooked meal that was high in lean red meat, low in carbohydrate (n= 10) or low in lean red meat, high in carbohydrate (n=10). Dietary fibre intake and macronutrients were kept constant. At the beginning and end of the study, three-day faecal samples were collected and by-products of protein fermentation and carbohydrate metabolism, undigested fibre residues, and faecal output and colonic bacterial microbiota changes measured.

Outcomes: No significant differences were observed in subjects on either diet when comparing faecal output, faecal pH, other faecal markers, nor faecal lactoferrin. There was a trend observed in changes in the population of colonic microbiota using FISH analysis. Bacteroides spp. and Prevotella spp. appeared to decrease in women consuming a high red meat diet compared with an increase in women consuming a high carbohydrate diet.

Conclusions: In this pilot study the trend in colonic microbiota change is interesting and suggests that dietary influence of colonic microbiota, especially changes in Bacteroidetes, may be indicative of risk of gut damage and disease compared to other faecal markers.

Illness representations and cancer screening in older women

This research investigated why some older women do not obtain screening mammograms and Pap smear tests. In-depth interviews found many beliefs which are contrary to screening and influenced the women's screening behaviour.

Older women and sternotomy

Explores the experiences of older women having a sternotomy incision following cardiac surgery. Older women account for a large proportion of patients undergoing cardiac surgery each year in Australia. The context from which they face cardiac surgery is unlike that of men and of younger women, and there has been limited exploration of their experiences.

Ways in which 'community' benefits frail older women's well-being : '... we are much happier when we feel we belong'

Aim: This paper aims to explore frail older women’s lived experiences of ‘community’ and which aspects of ‘community’ they perceive as beneficial to their well-being.

Method: This qualitative project used a mixed methodological approach which integrated aspects of descriptive phenomenology and grounded theory. Ten frail, older women residing in South East Melbourne, Australia participated in in-depth interviews.

Results: This research obtained a rich and detailed account of the aspects of ‘community’ identified by participants as enhancing their well-being. These included: social contact, community dynamics, feelings of support and positive orientation.

Conclusion: This paper has increased our understanding of the factors supporting well-being of frail older women. Service providers should actively consider how they can strengthen these factors to improve social connectedness for frail older women by the use of volunteers, developing social networks and increasing availability and quality of community-based activities.

Older women crafting ethical subjectivities in rural places

Over the last two years my colleagues and I conducted research conversations with older women living in rural Victoria about the meaning of craft in their lives. These conversations are the basis for our speculations on how women constitute ethical subjectivities through specific craft activities and through their engagement with Country Women Association (CWA) craft groups. The CWA is recognised as a ‘community of practice’ with local, regional, state, national and global networks, aiming to improve the lives of rural people. The focus of this paper, however, is on how ethical subjectivities by rural women are fashioned through specific involvements in craft activities and craft groups. I aim to elaborate on how Foucault’s later work on the ‘Care of the Self’ may open possibilities, even if limited, for understanding the complex ways women take up subject positions in interaction with historical, political, economic and social arrangements, and through engagement with specific institutions. For Foucault, ‘care of the self’ is an inherently social practice. Currently, modern power relations incite us to relate to our selves through self confessional and self-disciplining technologies. Could a differently constituted mode of self-care be drawn from the Ancient Greeks to offer us ideas for enacting personal and social transformations today?

Annual feedback is an effective tool for a sustained increase in calcium intake among older women

We aimed to optimize calcium intake among the 2,000+ older women taking part in the Vital D study. Calcium supplementation was not included in the study protocol. Our hypothesis was that annual feedback of calcium intake and informing women of strategies to improve calcium intake can lead to a sustained increase in the proportion of women who consume adequate levels of the mineral. Calcium intake was assessed on an annual basis using a validated short food frequency questionnaire (FFQ). Supplemental calcium intake was added to the dietary estimate. Participants and their nominated doctor were sent a letter that the participant’s estimated daily calcium intake was adequate or inadequate based on a cutoff threshold of 800 mg/day. General brief statements outlining the importance of an adequate calcium intake and bone health were included in all letters. At baseline, the median daily consumption of calcium was 980 mg/day and 67 percent of 1,951 participants had calcium intake of at least 800 mg per day. Of the 644 older women advised of an inadequate calcium intake at baseline (< 800 mg/day), 386 (60%) had increased their intake by at least 100 mg/day when re-assessed twelve months later. This desirable change was sustained at 24 months after baseline with almost half of these women (303/644) consuming over 800 mg calcium per day. This study devised an efficient method to provide feedback on calcium intake to over 2,000 older women. The improvements were modest but significant and most apparent in those with a low intake at baseline. The decreased proportion of these women with an inadequate intake of calcium 12- and 24-months later, suggests this might be a practical, low cost strategy to maintain an adequate calcium intake among older women.

Trials and tribulations of recruiting 2,000 older women onto a clinical trial investigating falls and fractures : vital D study

Background Randomised, placebo-controlled trials are needed to provide evidence demonstrating safe, effective interventions that reduce falls and fractures in the elderly. The quality of a clinical trial is dependent on successful recruitment of the target participant group. This paper documents the successes and failures of recruiting over 2,000 women aged at least 70 years and at higher risk of falls or fractures onto a placebo-controlled trial of six years duration. The characteristics of study participants at baseline are also described for this study.

Methods The Vital D Study recruited older women identified at high risk of fracture through the use of an eligibility algorithm, adapted from identified risk factors for hip fracture. Participants were randomised to orally receive either 500,000 IU vitamin D3 (cholecalciferol) or placebo every autumn for five consecutive years. A variety of recruitment strategies were employed to attract potential participants.

Results Of the 2,317 participants randomised onto the study, 74% (n = 1716/2317) were consented onto the study in the last five months of recruiting. This was largely due to the success of a targeted mail-out. Prior to this only 541 women were consented in the 18 months of recruiting. A total of 70% of all participants were recruited as a result of targeted mail-out. The response rate from the letters increased from 2 to 7% following revision of the material by a public relations company. Participant demographic or risk factor profile did not differ between those recruited by targeted mail-outs compared with other methods.

Conclusion The most successful recruitment strategy was the targeted mail-out and the response rate was no higher in the local region where the study had extensive exposure through other recruiting strategies. The strategies that were labour-intensive and did not result in successful recruitment include the activities directed towards the GP medical centres. Comprehensive recruitment programs employ overlapping strategies simultaneously with ongoing assessment of recruitment rates. In our experience, and others direct mail-outs work best although rights to privacy must be respected.

Annual high-dose oral vitamin D and falls and fractures in older women : a randomized controlled trial

Context Improving vitamin D status may be an important modifiable risk factor to reduce falls and fractures; however, adherence to daily supplementation is typically poor.

Objective To determine whether a single annual dose of 500 000 IU of cholecalciferol administered orally to older women in autumn or winter would improve adherence and reduce the risk of falls and fracture.

Design, Setting, and Participants A double-blind, placebo-controlled trial of 2256 community-dwelling women, aged 70 years or older, considered to be at high risk of fracture were recruited from June 2003 to June 2005 and were randomly assigned to receive cholecalciferol or placebo each autumn to winter for 3 to 5 years. The study concluded in 2008.

Intervention 500 000 IU of cholecalciferol or placebo.

Main Outcome Measures Falls and fractures were ascertained using monthly calendars; details were confirmed by telephone interview. Fractures were radiologically confirmed. In a substudy, 137 randomly selected participants underwent serial blood sampling for 25-hydroxycholecalciferol and parathyroid hormone levels.

Results Women in the cholecalciferol (vitamin D) group had 171 fractures vs 135 in the placebo group; 837 women in the vitamin D group fell 2892 times (rate, 83.4 per 100 person-years) while 769 women in the placebo group fell 2512 times (rate, 72.7 per 100 person-years; incidence rate ratio [RR], 1.15; 95% confidence interval [CI], 1.02-1.30; P = .03). The incidence RR for fracture in the vitamin D group was 1.26 (95% CI, 1.00-1.59; P = .047) vs the placebo group (rates per 100 person-years, 4.9 vitamin D vs 3.9 placebo). A temporal pattern was observed in a post hoc analysis of falls. The incidence RR of falling in the vitamin D group vs the placebo group was 1.31 in the first 3 months after dosing and 1.13 during the following 9 months (test for homogeneity; P = .02). In the substudy, the median baseline serum 25-hydroxycholecalciferol was 49 nmol/L. Less than 3% of the substudy participants had 25-hydroxycholecalciferol levels lower than 25 nmol/L. In the vitamin D group, 25-hydroxycholecalciferol levels increased at 1 month after dosing to approximately 120 nmol/L, were approximately 90 nmol/L at 3 months, and remained higher than the placebo group 12 months after dosing.

Conclusion Among older community-dwelling women, annual oral administration of high-dose cholecalciferol resulted in an increased risk of falls and fractures.
