Influencing factors analysis of spontaneous knee joint osteoarthritis among middle aged and old aged pople in Xi'an

Objective:To explore the prevalence rate of knee joint osteoarthritis and its pathogenetic fea- tures among the middle-aged and old aged people in the urban and rural area of Xi'an.Methods:From May to October 2005,1538 Han nationality above 40 years in Xi'an were investigated according to strati- fied and cluster random sampling.The same questionnaire was delivered to subjects who had been given normotopia and lateral position radiographic examination in both knees.Excluded from etiological arthri- tis,some subjects with clinical symptoms and a radiographic grade (beyond Kellgren & Lawrence gradeⅡ) were finally diagnosed as spontaneous knee joint osteoarthritis.All analyses were performed with SPSS 13.0 and t test,U test.Single factor analysis and multiple logistic regression analysis were used to analyze dates.Results:The total prevalence of spontaneous knee joint osteoarthritis was 12.1% with 2.5% and 2.1% for right and left knees,respectively.The prevalence of knee joint osteoarthritis in wom- en was 2.5 times of that in men (17.2% vs 6.8%,P=0.000).the osteophyte prevalence in women was 2.3 times of that in men (26.5% vs 11.4%,P=0.000).The prevalence of knee joint osteoarthritis and osteophyte increased with the growth of age.So did the symptomatic knee,except for the age group of 56- 60 years and 66-70 years.The prevalence of symptomatic knee joint for urban area was significantly higher than that for rural area (56.3% vs 45.3%,P=0.003).In women,the prevalence of knee joint os- teoarthritis increased significantly with the increasing of body mass index,which had not been observed in men.Female and obesity are the risk factors for osteoarthritis,but bean and its products and meat could prevent the osteoarthritis.Conclusion:Old age,female and obesity serve as risk factors for knee joint os- teoarthritis.

Analysis of the Variations of Body Build of Middle-and Old-aged and Research on the Prototype

The characteristics of body build of middle - and old -aged women and its rule of variations as well as the basic sizes of various parts are discussed. All these are based on the body measurements of this age group, and also on the statistical studies of the measurement data. By setting the regression equation, the calculating formulae of various control parts are obtained, thus establishing the prototype of this age group for women.

Study on Body Form and Garment Size Series of the Middle Age and Aged People

This paper was designed to analyze on the data, which was obtained from 'National Physique Fitness Investigation Report (2000)'. In order to get the typical body form and figure type of the middle age and aged people, it was focused on the body form data of this group (age 40 - 60). After calculation and analyzing, the distinguishing feature of body form and the distribution of figure type were deduced. Finally, the re-classification of body form for Chinese middle age and aged people was suggested. It as also suggested that a new garment size series especially for the middle age and aged should be built to fit for these people. This conclusion would be useful and significant to design and production for clothing company, especially that who take the aged people as their target consumer.

By means of law and social policy, Russia can promote the active participation of the elderly in politics, economy, culture and other activities to promote the positive image of the elderly. The active aging policy in Russia and the development trend of the old-age care service to promote the social adaptation and re-employment of the elderly are of positive significance to the development of our country＇s old-age care service.

Delirium,insulin-like growth factor I,growth hormone in older inpatients

BACKGROUND Delirium is a common disorder in elderly medical inpatients with serious adverse outcomes and is characterized by sudden onset,disturbance in attention,awareness,consciousness and cognition,and often with behavioural disturbances.Central to understanding delirium,is understanding mechanisms by which body and brain wellbeing are linked and in particular how brain responses to bodily homeostatic stress is mediated.A number of studies have investigated the relationship between insulin-like growth factor I(IGF-I)and delirium in medically ill hospitalised patients with conflicting results.However,none have investigated growth hormone(GH)which is related to IGF-I via negative feedback.AIM To investigate the relationship between serum levels of IGF-I and GH,and the occurrence of delirium.METHODS Prospective,longitudinal,observational study.Consecutive elderly inpatients(aged 70+),were assessed twice weekly with Montreal cognitive assessment(MoCA),Confusion assessment method(CAM),Acute Physiology and Chronic Health Evaluation II.Delirium was defined using CAM.Previous history of dementia was evaluated with the Informant Questionnaire on Cognitive Decline in the Elderly.IGF-I and GH levels were estimated with the ELISA method.Generalized estimating equations(GEE)model was applied for the first five assessments to analyze those longitudinal data.RESULTS The sample consisted of 198 participants(mean age 80.63±6.81;range 70-97).Of these 92(46.5%)were females.Eighty six(43.4%)were identified with a history of dementia.Incident or prevalent delirium during hospitalisation was identified with CAM in 40 participants(20.2%).Evaluation of missing values with Little's MCAR test indicated that they were missing completely at random(MCARχ2=12.24,u:9,P=0.20).Using GEE for the analysis we found that low MoCA scores,low levels of IGF-I and high levels of GH were significantly associated with any delirium(prevalence,incident,or fluctuating,during the study period(Waldχ2=12.231;u:1,P<0.001,Waldχ2=7.196,u:1,P=0.007,Waldχ2=6.210;:u:1,P=0.013 respectively).CONCLUSION The results show that low levels of IGF-I,high levels of GH and low scores in cognition are independently associated with the occurrence of any delirium during the hospitalisation of medically ill older people.The results of the study supports the hypothesis that deficits in the immunoreactivity of the brain(low cerebral reserve)may be associated with delirium.

Relationship among Health Related Quality of Life, Quality of Sleep, and Oral Health Condition

Japan’s aging rate (ratio of elderly aged 65 and older to total population) has exceeded 20%. The aim of this study was to clarify the relationships between Health Related Quality of Life, Body Mass Index (BMI), and sleep quality. Subjects were 51 adults over 55 years old with chronic disease who living in the community. Instruments and structured interviews were used giving due consideration to privacy. Interviews were conducted within 10 - 20 minutes at the out-patient department. The evaluation instruments included bodymass index, Pittsburgh Sleep Quality Index (PSQI), Health Related Quality of Life (HRQOL), and Oral Health Impact Profile (OHIP-14). A significant positive correlation (ρ = 0.321, p < 0.05) between PSQI and QOL (OHIP-14) scores was confirmed with sleep quality being lower with lower QOL scores. A negative correlation (ρ = ?0.339, p < 0.05) between physical health component summary scores (PCS) and mental health component summary scores (MCS) of HRQOL was confirmed, demonstrating that PCS was low, and the level of MCS was high. Sleep quality was found lower among those with lower oral health-related QOL scores. Moreover, in subjects with lower MCS scores, the PCS scores were found to be higher. Accordingly, it was considered appropriate that dental treatment and care, support the maintenance of activities and sleep, and mental health promotion which are likely requisites critical for elderly persons’ maintenance of independent lifestyles in their familiar community.

Effect of Bushen Hemai decoction on vascular stiffness in elderly patients with isolated systolic hypertension

Objective: To investigate the effect of Bushen Hemai decoction on the wall stiffness of middle-aged and elderly patients with simple systolic hypertension. Methods: The 126 middle-aged and elderly patients with simple systolic hypertension admitted to our hospital from May 2010 to May 2015 were randomly divided into control group (63 cases) and observation group (63 cases). The control group was treated with conventional Western medicine, while the observation group was treated with Bushen Hemai decoction on the basis of the control group. The two groups were treated for 4 weeks. Results: The systolic blood pressure of the two groups decreased after treatment (observation group: T=16.165, control group: T=13.537, P<0.05);the systolic blood pressure of the two groups did not change significantly after treatment (observation group: T=1.857, control group: T=0.483, P>0.05);the systolic blood pressure of the observation group was lower than that of the control group after treatment (T=16.165, P<0.05). After treatment, the level of ST segment of ECG in the two groups was lower than that before treatment (observation group: T=22.145, control group: T=11.007, P<0.05);after treatment, the level of ST segment of ECG in the observation group was lower than that in the control group (T=8.130, P<0.05). After treatment, the pulse conduction velocity of the two groups was lower than that of the control group (observation group:T=8.694, control group: T=3.944, P<0.05);after treatment, the pulse conduction velocity of the observation group was lower than that of the control group (T=5.326, P<0.05). The total effective rate of the observation group (93.65%) was higher than that of the control group (76.19%) (P<0.05). Conclusion: Bushen Hemai Decoction has a significant clinical effect on middle-aged and elderly patients with simple systolic hypertension, and can improve the stiffness of the tube wall, which is worthy of clinical reference.
