Midlife women's perceptions of their changing bodies: an ethnographic analysisBanister, Elizabeth M. 31 July 2018 (has links)
The purpose of this study was to document, from a developmental perspective, midlife women's perceptions of their changing bodies within the larger cultural context, and to use ethnographic research as a tool for researching midlife women. The central question guiding the analysis of midlife women's lives was: What are midlife women's perceptions of their changing bodies? The self-reported experiences of 11 midlife women (ages 40–55) were obtained and the data analyzed using Spradley's (1979) Developmental Research Sequence Method.
Data were collected by using individual and group interviews. During the individual interviews, three kinds of ethnographic questions (descriptive, structural, and contrast) were used to explore how each woman conceptualized her experiences. After the individual interviews were completed, three consecutive group interviews were conducted. The group interviews provided a context for determining the women's shared meaning of their changing bodies at this pivotal time of their development. To solidify the credibility of this qualitative study, the understandings derived from the study were subjected to member checking and the application of content analysis.
Four general themes emerged from the analysis of the data. The first two themes—the media and medicine—involved aspects of the culture that most influenced the women's interpretations of their changing bodies and were, therefore, structural in nature. The second two themes—loss, and redefining of self (including the development of self-care)—involved the more personal aspects of the women's narratives such as reflected meanings and attitudes.
Results of the study indicated that the midlife period in a woman's life encompasses a broad spectrum of experience, full of contradiction and change. Issues of loss, change in role functions, cultural influences that perpetuate ageism and sexism, ambivalence, strong emotional responses, lack of consistent information about menopause and sexuality, questioning, critical reflection, coping mechanisms, redefining self self-care—all played a central role in the women's lives during this important time of transition.
Midlife events prompted the participants to question and challenge traditional cultural expectations about female roles and behavior; and in this way they reinterpreted their experiences and created new meaning from them. The women reformulated their self-definitions from that of caregiver to care receiver, from caring for others to caring more for oneself. This could be seen as a major developmental change in the women's lives, since through this process of facing the challenges of midlife, the women moved from self definitions that were based on negative cultural stereotypes to self definitions that were based on an affirmation of their ability to experience the events of their existence as autonomous individuals, less bound by stereotypes than they had been before.
Health professionals can attempt to examine some of their own biases and assumptions about midlife women that could influence their treatment of, and attitudes towards, these women. Furthermore, health professionals are in the position to help their midlife clients question and become critically aware of the social, historical, and political context that defines women's midlife experience, so that midlife women need not take for granted the established interpretation of their physical changes. Suggestions for further research are included. / Graduate

Menopause, Middle Age, and the Social WorkerVatter, Bonnie C. 01 January 1978 (has links)
The central thesis of this paper is that the social work profession needs to know much more about menopause and its concomitants in order to enhance diagnosis and treatment. Unfortunately, the woeful lack of research and consequent paucity of data on the subject require a heavy reliance upon intuitively plausible statements in support of larger propositions about many of the strategic relationships advanced in the course of the argument. When these propositions and statements are taken as a whole, the paper is also an outline of essential research topics.

Energy and nutrient intake, and body composition of elderly women with different ages and levels of physical activityBell, Elizabeth J. 17 March 1993 (has links)
The US population over the age of 65 years is growing rapidly, with elderly
women outnumbering men by 50 percent. Studies show that aging is often
accompanied by reduced energy intake, inadequate nutrition, and the loss of lean
body mass with a subsequent increase in body fat, as well as the tendency towards
inactivity. An increased level of physical activity elevates energy needs, which can
lead to increased energy and nutrient intake, and has been shown to aid in the
maintenance of lean body mass and the reduction of body fat. Positive health
outcomes for seniors depends partly on a clearer understanding of the
interrelationships between physical activity, diet, and body composition.
The purpose of this study was to determine whether higher overall levels of
physical activity among elderly women, were related to higher energy intake, nutrient adequacy, and less body fat, and to what extent age affected these
associations. Sixty-three elderly women (aged 65-98 years) volunteers completed a
three part study spanning 14 weeks. Mean level of physical activity (MLPA) and
mean nutrient intakes were estimated using nine self-reported days of records, three
predetermined days from each of three recording periods. MLPA was determined
from self-reported hours spent in five physical activity categories (resting, very
light, light, moderate, and heavy), multiplied by corresponding weighted factors of
intensity (1.0, 1.5, 2.5, 5.0, 7.0, respectively). Nutrient analyses for seven
vitamins (vitamin A, vitamin C, thiamin, riboflavin, niacin, vitamin B6, vitamin
B12) and three minerals (calcium, iron, and zinc) were done using the Food
Processor II computer software. A mean adequacy ratio (MAR) was calculated for
each subject as the average percent of the RDA for intakes of all 10 nutrients.
Body composition assessment included triplicate measures of: height and weight
from which body mass index (BMI) was determined; waist-to-hip ratio (WHR); and
an estimation of percent body fat (PBF) from the sum of four skinfolds (triceps,
biceps, subscapular, suprailiac).
It was determined that MLPA was not directly related to energy intake,
nutrient adequacy, or the three body composition parameters. However, the
correlation coefficients between MLPA and energy intake, mean adequacy ratio, and
percent RDA for 8 of the 10 nutrients were positive, and the correlation coefficients
between MLPA and all three body fatness measures were negative, as was expected. The small coefficient of variability of MLPA limited its discriminating power in
determining associations with energy intake, nutrient adequacy, and body
composition.
Backward stepwise regression models were conducted to distinguish potential
confounding effects of age, education, and MLPA on the variables kcal/day,
kcal/kg/day, MAR, BMI, WHR, and PBF. Age was found to account for the
largest portion of the variations, and was greater than the contribution of MLPA for
all of these variables, except in the case of kcal/kg/day.
When the subjects were divided into young-old (65-74 yr) and old-old (75-98
yr) subgroups, the younger compared to the older women were found to be more
active as measured by MLPA (p=.02), explained by their engaging in more light
activities of daily living (p=.04). The young-old compared to the old-old women
consumed more kcalories/day (p=.01), and had a higher MAR score (p=.00). The
nutrient densities of the two groups' diets were not significantly different. The
younger women had slightly lower BMI, WHR, and PBF values.
This study revealed age, rather than MLPA, was a better predictor of some
parameters of diet adequacy and body fatness among this sample of elderly women.
In addition, consistently higher levels of physical activity and greater dietary
adequacy and was found among the younger compared to the older portions of this
sample of senior women, suggesting that nutrition intervention programs for the
elderly should encourage daily activeness as a strategy to maintain or improve
dietary adequacy with advancing age. / Graduation date: 1993

Dietary behavior and body composition parameters among self-reported exercising and non-exercising elderly womenBell, Kathleen A. 15 March 1993 (has links)
The percentage of the American population who are 65 years old or older is
rapidly increasing, especially the proportion of women. It is becoming crucial to
encourage lifestyle behaviors that will enable senior women to remain in optimal
health. Following the 1990 Dietary Guidelines' recommendations to limit fat intake
and consume adequate amounts of dietary fiber has been shown to positively impact
longevity and health status in the elderly by decreasing risk factors for chronic
diseases. An expected outcome of engaging in regular exercise is a reduction in
body fat, which is also associated with a lowered incidence of several chronic
illnesses. However, the literature clearly indicates that nutritional quality of the diet
and involvement in regular exercise decrease with increasing age. There is evidence that, with the adoption of one health enhancing behavior, there is a greater tendency
to engage in other health promoting behaviors, but little data exist on the healthseeking
behaviors of older adults.
The purpose of this study was to ascertain if there were identifiable
differences between self-defined exercising and self-defined non-exercising elderly
women with respect to their nutrient intake, food sources of dietary fat and fiber,
dietary change behavior, and body composition parameters, considering their age
and education and income levels. The objective was to determine whether those
women who had consciously undertaken a regular exercise program would also have
higher micronutrient intakes, make lower fat and higher fiber food choices, report
having made more dietary changes in the direction of the 1990 Dietary Guidelines,
and have leaner body compositions than those who had not undertaken such a
program.
Thirty-three elderly women self-reported exercisers (mean age 74.1 years)
and 30 self-reported non-exercisers (mean age 71.3 years) were enrolled in a 14
week study. Exercisers were defined as those who reported having engaged in a
regular program of planned exercise a minimum of 15 minutes per session, 2 times
per week, for at least the last year, and non-exercisers were those who had not.
They kept three, 7-day food records at 5 week intervals. Nutrient intake was
estimated from 9 days of food records, 3 predetermined days from each recording
period, using the Food Processor n software. Dietary intakes were analyzed for
energy, macronutrients, dietary fiber, and selected micronutrients. Food sources of dietary fat and fiber were determined using a food categorization adapted from
Popkin and coworkers (1989). Information concerning dietary change behavior,
obtained from questionnaire responses, was compared between groups using chisquare
tests. Body composition, assessed through repeat measurements during each
dietary recording period, included determination of percent body fat through
skinfolds, waist-to-hip-ratio and body mass index. Average 9-day nutrient intakes
and anthropometric measures were compared between groups using t-tests or Mann-
Whitney U tests.
Both elderly women exercisers and non-exercisers had similar energy,
macronutrient, and dietary fiber intakes based on 9-day means. Their total fat
intakes, expressed in grams and as percentages of energy, were not significantly
different. Both groups consumed a lower percentage of their daily kcalories as total
fat (32%) compared with national surveys of women over 65 (36%). Exercisers
consumed more total vitamin A (p=.03) and carotene (p=.00) than the non-exercising
women. A great proportion of both groups did not meet 75 % of the
Recommended Dietary Allowances for calcium and zinc. A larger proportion of the
exercisers than the non-exercisers reported using lower fat cheese (p=.02) and green
and yellow vegetables (p=.03), which partially explained their higher total vitamin
A and carotene intakes. Exercisers obtained less of their total fat intake from lower
fat milk (p=.02) and more of their fat intake from lower fat lunch meats (p=.04)
than the non-exercisers. The categories of legumes (p=.02) and lower fiber
vegetables (p=.05) supplied greater amounts of dietary fiber for the exercisers compared with the non-exercisers. When asked about dietary changes made over
the past decade, a greater percentage of the exercisers than non-exercisers reported
having decreased red meat intake (p=.05) and increased consumption of cereals
(p=.05) and legumes (p=.00). Actual intake data showed that the legume food
category contributed more dietary fiber to the diets of the exercisers than the non-exercisers
(p=.02).
No differences were found in body fat measures between the exercisers and
non-exercisers. The lack of observed differences between the two groups reinforces
what other researchers have found, that a large number of factors influence body
composition, of which exercise is only one. More research is needed to distinguish
the interactions of age, energy intake, and physical activity on the body fatness of
elderly women, as well as the most accurate instruments for assessing body
composition for this age group.
Exercise participation among elderly women in this study appeared to be
associated with several positive dietary behaviors. Elderly women exercisers
compared to non-exercisers made food choices leading to higher total vitamin A and
carotene intakes, and also reported making more changes in food consumption
behaviors in the direction of current dietary recommendations. These observed
outcomes provide support for designing health-promotion programs for elderly
women which include both nutrition education and exercise components. / Graduation date: 1993
