Predictors of low bone mineral density in elderly males with chronic obstructive pulmonary disease: the role of body mass index

Objective.?The aim of this study was to investigate the relationships between nutritional indices (Body mass index (BMI), serum albumin), sarcopenia, bone mineral density (BMD) and the severity of their pulmonary obstruction in elderly patients with chronic obstructive pulmonary disease (COPD).

Methods.?The method involved was a prospective transversal study; 82 males >65 years old, 41 stable patients with COPD and 41 healthy elderly individuals (controls). All subjects underwent spirometry, biochemical analyses and dual energy X-ray absorptiometry. The significance of the differences between mean values and prevalence rates was tested. The relationships between BMD and independent predictors were analysed by multiple linear regressions. Logistic regression models were applied on dichotomised variables.

Results.?In patients with COPD, the prevalence of osteoporosis was higher in subjects with sarcopenia (46% vs. 0%; p?<?0.05) and with BMI?<?25.1?kg/m² (58% vs. 15%; p?<?0.02). Multiple regression analysis indicated that BMI, appendicular skeletal muscle mass (ASMM), albumin, and forced expiration volume after 1?s (FEV1) explained the 70% of BMD variability at the hip and 56% at the spine. Logistic regression showed that a BMI?<?25.1?kg/m² was independently associated with osteoporosis risk (OR?=?10.0; 95%CI 1.3–76); no independent effect emerged for FEV1% (<and ?50%).

Conclusion.?In elderly males with COPD, the BMI values?≤25?kg/m² are more strongly related to low BMD levels than albumin values. Among those patients, BMI values within the normal range for younger adults might point out a higher risk of osteoporosis.     

Body Dissatisfaction: Commitment,Support, and Trust in Romantic Relationships

Research investigating dimensions of relationship quality has suggested that aspects of relationship quality (e.g., commitment, support, trust) are related to lower levels of body dissatisfaction in women. However no studies have examined the effect of all three measures of relationship quality on body dissatisfaction simultaneously. Trust and support correlated with body dissatisfaction in men and women. Additionally, the results showed that lack of support is a predictor of body dissatisfaction in men and lack of trust is a predictor in women; relationship commitment did not appear to relate to body dissatisfaction.     

How to improve gait and balance function in elderly individuals—compliance with principles of training

Most balance training regimens for elderly individuals focus on self-controlled exercises, although automatic postural responses after a balance perturbation are not under direct volitional control. We critically review the literature on this topic, and notice that several studies fail to comply with basic principles of training and therefore show little improvement in function. Some present the view that physical function in the too frail and too fit cannot be improved, which we instead argue would be the effect of nonspecific training programs. We propose a concept for balance training that incorporates voluntary exercises as well as perturbation and dual-task exercises to improve balance control. The program is performed on five different levels where levels 1–4 exercises focus on the skill to maintain balance and level 5 adds perturbation exercises that focus on the skill to recover balance as well as dual task exercises providing a cognitive load during execution of a balance motor task. Functional requirements for muscle strength and power are directly incorporated into the program. The feasibility of the concept has been demonstrated on elderly fallers. A randomized control trial is underway to investigate the effects on healthy elderly individuals. Further intervention studies using this concept are encouraged.     

Perceptions of Body Image

Abstract

Perception of body image is an important component of self-concept and self-esteem. It has significant influence on work performance, a sense of physical attractiveness and incidents of health problems, such as anorexia. Negative perceptions of others by employees and supervisors can lead to violations of the Americans with Disabilities Act.     

Implementation of physically active lessons: A 2-year follow-up

Combining physical activity and academic content is a promising way to improve health and academic learning in schoolchildren. This paper examined the continuation of physically active lessons (PAL) in five Norwegian elementary schools, two years after a 10-month intervention period, which consisted of weekly minimum 2 x 45 min of PAL. Data were collected through semi-structured interviews with nine teachers and five school leaders. The Level of Use instrument was used to assess how the teachers integrated PAL into the school day. Two years after the intervention period, seven of nine teachers conducted PAL regularly, on average one lesson per week. Teachers’ implementation progress varied from struggling with logistics, to stable routine and creative adaption. Perceived benefits for the children, active leadership, and ongoing implementation support seem important for continuation. Introduction of PAL as a school development project, systematic planning from the onset and a gradual introduction of PAL, can be an effective strategy for continuation and long-term sustainability. In addition, the Level of Use instrument was useful to better understand which support mechanisms are needed at different stages in the implementation of PAL.

Internet Pornography use and Sexual Body Image in a Dutch Sample

Objectives: A commonly attributed cause of sexual body image dissatisfaction is pornography use. This relationship has received little verification. Methods: The relationship between sexual body image dissatisfaction and Internet pornography use was tested using a large-N sample of Dutch respondents. Results/Conclusion: Penis-size dissatisfaction is associated with pornography use. The relationship between pornography use and breast-size dissatisfaction is null. These results support prior speculation and self-reports about the relationship between pornography use and sexual body image among men. These results also support a prior null finding of the relationship between breast-size satisfaction for women and pornography use.     

Housing price, elderly dependency and fertility behaviour

Sustaining declines in fertility have increasingly become an alarming issue in most of the world economies. Many governments have been making enormous efforts to alleviate such intertwined problems as falling fertility and soaring elderly dependency. What really makes fertility rates fall? Does housing price have a role (as many argue)? Most researchers addressed this issue from a demographic perspective, but have yet to fully unravel the mystery of human fertility behaviour. The paper aims to investigate the novel linkages between birth rate, housing price and elderly dependency, with the case of Hong Kong. It employs two key methods: (i) the Autoregressive Distributed Lag (ARDL) to co-integration procedure and (ii) Granger causality, to disentangle the complicated relationships, long-run and short-run. The empirical results show that a 1 percent increase in housing prices and elderly leads to 0.52% and 1.65% decreases in birth rate respectively. Besides, both housing price and elderly dependency Granger cause birth rate in the long-run. Our findings not only shed light on fertility behaviour, but also provide implications for policy change. That is particularly relevant to those economies whose low fertility situations need to be ameliorated.     

我国校园暴力现象研究的再思考

当前,学界对校园暴力的研究主要沿用了传统的问题—对策范式,从研究侧重点不同可以区分为现状描述型、问题探析型和对策建构型三种研究类型。但是,由于传统的问题—对策范式无法从主体体验去解读校园暴力,使得相关研究具有一定局限性。从身体社会学的视角出发,不仅可以发现被传统研究范式遮蔽的议题,还可以从身体与结构互构的途径来理解校园暴力现象,为当前校园暴力研究提供了一个新的研究路径。     

Body mass index and functional status in community dwelling older Turkish males

Abstract

Objectives: To assess sex hormones in men with obesity and prostate cancer (PCa) and to study association between androgens and the pathogenesis biology of PCa in vitro.

Subjects and methods: One hundred and eighty-one men older than 45?years selected from of a population attending to Urology departments screening for PCa, (78 participants without PCa and 103 patients with PCa). All participants were assessed for body mass index (BMI), age, Gleason score, and PSA. Endocrine profile was determined for LH, total testosterone (TT), 17β-estradiol (E2), prolactin and leptin. Biochemical profile (HbA1c, triacylglycerols and lipoproteins) was also determined. In vitro experiments were also performed, involving the study of 5α-dihydrotestosterone (DHT) and E2 in the presence of adipocyte-conditioned medium (aCM).

Results: All variables were continuous and described a Gaussian distribution unless mentioned. To determine the relation of aggressiveness, variable were transformed into categories. Thus, PCa aggressiveness is associated with the increase of age and BMI (p?<?.0001) but with is decreased with TT and E2 (p?<?.05). Moreover, adipocyte-secreted molecules increase aggressiveness of PCa cells in vitro. Lastly, DTH but not E2 enables invasiveness in vitro.

Conclusions: It was observed a coexistence of hormone axis profile alteration with sex hormones and BMI in PCa patients, in accordance with the new perspective of PCa pathogenesis.     

Body image,self-esteem,and behavioral risk for chronic disease among college students: Additional evidence for integrated prevention

Abstract

Objective: To examine associations between two body image constructs (body appreciation and body satisfaction) and five health behaviors (diet, physical activity, weight management, tobacco exposure, and alcohol intake) associated with risk for chronic disease, controlling for self-esteem. Participants: Three hundred and forty-four college students enrolled at a large, public university in the southeastern US. Methods: Students completed an online survey composed of measures of body appreciation, body satisfaction, self-esteem, and frequency of engagement in preventive health behaviors. Hierarchical linear regression models were used to assess relationships between constructs. Results: Body appreciation, but not body satisfaction or self-esteem, significantly and positively predicted engagement in diet-, physical activity-, and weight-related health behaviors. No associations were found for substance use outcomes. Conclusions: Results illuminate health risks among college students and provide additional evidence to support the development of holistic preventive interventions that simultaneously address aspects of mental and physical health among college students.     

Shock wave lithotripsy for ureteral stones in elderly male patients

Introduction.?Age has never been considered as a factor in the treatment of ureteral stones, but elderly male patients may suffer from concomitant illnesses that may affect SWL results, such as voiding difficulties and musculo-skeletal and cardio-vascular disorders. The aim of this study was to assess the success rate and complications of shock wave lithotripsy (SWL) for all size and location ureteral stones in patients older than 70 years of age.

Patients and Methods.?We retrospectively reviewed the charts and radiology films of all patients who had undergone SWL for ureteral stones with the HM3 lithotriptor and compared the results of patients younger than 70 years to those older than 70 years.

Results.?During 2000–2003, 238 consecutive male patients (23 older than 70 years) underwent SWL under regional anesthesia for all size and locations ureteral stones. Stone sizes, locations, opacity, and pre-operative drainage procedures matched in both groups. The overall stone-free rate was 91% for both groups. Complications were recorded in 1% of the older patients and 3.7% of the younger ones. No treatment-related mortality was recorded.

Conclusions.?Age itself has no effect on the success rate of SWL with the HM3 lithotripter for ureteral stones. In general, SWL treatment showed a high success rate with minimal morbidity and no treatment-related mortality.     

Body shopping: Maternity and alterity in Mamatoto

ABSTRACT

The products and practices of The Body Shop, both material and rhetorical, can be inserted into a number of competing discourses along the axes of feminist interests in the body and its relation to culture. We focus here on The Body Shop's Mamatoto range as it relates to contemporary Western discursive formations of maternity, alterity, and the vexed constructions of ‘difference’ and ‘globalism’ that emerge from them. Among the meta-products of Mamatoto are discursive formations of the body itself which, while they appear to endorse, even to celebrate, an active engagement with transcultural specificity and difference, actually reinstate the Western, white body of ‘woman’ as the ‘gold standard’ against which the exoticized currency of other women can be classified, appropriated and disowned. Within this framework, maternity itself is deployed by The Body Shop as a richly suggestive trope that serves to represent the problematics of body-as-nature, body-as-culture and body-as-identity that continue to preoccupy feminists across a wide range of political and cultural agendas.     

Effects of testosterone treatment on body composition in males with testosterone deficiency syndrome

Abstract

Objective: We evaluated the safety of testosterone treatment and its efficacy on body composition in males with testosterone deficiency syndrome (TDS) over 24 months.

Methods: 50 males aged 50–65 years with TDS (Aging Males Symptoms Scale [AMS]?>?26 and calculated free testosterone [cFT] 250?pmol/l) were administered 50?mg testosterone gel daily for one year. During the second year, patients received 1000?mg of testosterone undecanoate every 2–3 months. Outcome measures were clinical chemistry values and total testosterone; sex hormone-binding globulin and cFT, changes in AMS and International Prostate Symptom Score; and changes in body composition measured by dual-energy-x-ray absorptiometry.

Results: There were no clinically significant changes in clinical chemistry safety parameters. There were significant improvements in both total and cFT and in AMS scores after three months (p?<?0.001). Lean mass increased 2.35% at 12 months and 4.5% at 24 months, but proportionally more muscle mass was gained in arms and legs than in the trunk. Fat mass decreased 4.2% at 12 months and 9.1% at 24 months.

Conclusions: Testosterone treatment in males with TDS leads to body changes affecting lean and fat mass with significant improvement in AMS scores, and has an excellent safety profile.     

Spillover Impacts of a Reproductive Health Program on Elderly Women in Rural Bangladesh

This paper extends the program evaluation literature by investigating intra-household externalities generated by a reproductive health program, administered as a quasi-control experiment in rural Bangladesh. Although the program targeted only mothers and children in randomly selected treatment areas, using a reduced form demand approach and data from Matlab Health and Socio-economic Survey of 1996, we found a significantly positive spillover impact of this reproductive health program on the health of the never-targeted elderly women.

The microanatomy of trabecular bone in young normal and osteoporotic elderly males

Normally there is a gradual continual loss of cortical and trabecular bone in both men and women as they age. Osteopenia and osteoporosis are conditions in which the loss results in brittle bones that fracture easily. Males with low testosterone and hypogonadism are predisposed to osteoporosis and prevention tends to be overshadowed by the greater problem in postmenopausal women. The ability of the skeleton to resist external forces depends partly upon the amount of bone present and partly upon other factors including cancellous bone microarchitecture. This is examined in iliac crest bone biopsies from idiopathic osteoporotic men, mean age 60 ± 12 SD years [n = 16]. These were compared with a healthy control group (autopsy samples), mean age 30 ± 8.9 years [n = 28] with the aim of examining the pattern of cancellous atrophy in male idiopathic osteoporosis. Undecalcified specimens were embedded in methylmethacrylate and prepared for histomorphometry. Sections were analysed using an automated trabecular analysis system (TAS), whereby a binary image was created. Area measurements including the trabecular surface and distance measurements including the trabecular width were made. The binary image was thinned to its medial framework and the node and terminus number as indices of trabecular interconnection were recorded, together with the strut length. Results (median (range)) showed a lower percentage bone volume in the elderly osteoporotic male, 10.2% (5.4–23.1) compared to young normals 25.2% (14.6–43.9), p < 0.001. The trabeculae tended to be thinner, 95.7 µm (66.7–170.7) c.f. 120.8 µm (75.8–208.6) and considerably fewer in number, 11.1 (2.1–31.4) c.f. 48.3 (25.4–66.9), p < 0.001 per field and in particular the number of nodes, 2.1 (0.15–14) c.f. 40.6 (10.3–74.1) per field and the node: terminus ratio fell to 0.13 (0.01–1.19) c.f. controls 0.98 (0.24–6.69), p < 0.001. It was concluded that the pattern of cancellous atrophy in male idiopathic osteoporosis differs from normal aging and resembles that in postmenopausal women. Results using the automated TAS confirm previous observations made manually.     

Batteries assessing health related fitness in the elderly: a brief review

Evaluation of physical functioning is a key issue in clinical geriatrics and in aging research. In recent years, different physical performance batteries in which individuals are asked to perform several tasks and are evaluated using different criteria have been designed and used in elderly populations. These batteries include different types of test which range from basic motor abilities to relevant everyday activities, depending on the construct area in the domain of physical function that must be measured. This paper reviews and classifies the main physical functioning batteries that can be found in the scientific field of aging research in order to provide knowledge on selection, administration, and interpretation of this indispensable assessment tools.     

Intentions and strategies among elderly people: Coping in everyday life

Many studies of the elderly adopt a provider perspective, focusing on social policy, organizations, and professional groups. Less is known about how the elderly manage when they eventually need help in everyday living. This study examined the everyday behavior and strategies of the elderly through conducting semi-structured, in-depth interviews with 22 people over age 65. The intentions and strategies found revealed that the elderly managed or coped in active, adaptive, and passive ways, ranged along a continuum from actively maintaining their independence to passively depending on others.     

Estimation of elderly housing demand in an Asian city: Methodological issues and policy implications

Projection of elderly housing demands and needs has always been complex because of the volatility and heterogeneity of the factors involved. This paper argues that in a society where the tradition of elderly parents co-habiting with the children's family is breaking up, the projection of elderly housing demands for planning and policy purposes may not be scientifically possible. This owes to the impossibility to gauge housing affordability of the elderly by conventional indicators and the lack of information on the market behaviour of the elderly alone. This paper suggests the analysis of pre-retirement income, housing arrangements and housing aspiration to help elderly housing service providers to make more informed decisions. However, the projection of housing needs is more plausible if the underlying demographic projection models take care of major demographic trends such as household sizes and types, and if surveys are carried out to gauge housing aspirations of contemporary elderly persons. By using the above methods, the paper projected the future elderly housing needs and demands of Hong Kong, and found that public rental housing was perceived as the most secure type of housing regardless of affordability. This preference may reflect anomalies in elderly policies, particularly the lack of housing choices to suit the varied needs and affordability.
