Living alone, social support, and feeling lonely among the elderly

This study aimed to describe the characteristics of the elderly population living alone, and to examine how living alone relates to feeling lonely. Interviews were conducted with a stratified random sample of 4,859 elderly individuals living in Kaohsiung, Taiwan. Variables collected included demographic information, living alone or not, activities of daily living(ADL), instrumental activities of daily living (IADL), Short Portable Mental Status Questionnaire (SPMSQ), chronic conditions, perceived social support, and a subjective measure of feeling lonely. Using logistic regression, it was found that factors associated with living alone included gender, marital status, occupation, source of income, religion, and IADL. Living alone was, in tum, related to decreased levels of both perceived social supportand feeling lonely after adjustment for potential confounders. Managing retired life is important for adult elders, particularly for men. Lack ofsocial support is common among the elderly community who live alone, which could wel1 be a main reason for this group to feel lonely. As loneliness is linked to physical and mental health problems, increasing social support and facilitating friendship should be factored into life-style management forcommunities of elderly

Promoting transportation cycling for women: The role of bicycle infrastructure

Objective. Females are substantially less likely than males to cycle for transport in countries with low bicycle transport mode share. We investigated whether female commuter cyclists were more likely to use bicycle routes that provide separation from motor vehicle traffic. Methods. Census of cyclists observed at 15 locations (including off-road bicycle paths, on-road lanes and roads with no bicycle facilities) within a 7.4 km radius of the central business district (CBD) of Melbourne, Australia, during peak commuting times in February 2004. Results. 6589 cyclists were observed, comprising 5229 males (79.4%) and 1360 females (20.6%). After adjustment for distance of the bicycle facility from the CBD, females showed a preference for using off-road paths rather than roads with no bicycle facilities (odds ratio [OR]=1.43, 95% confidence interval [CI]: 1.12, 1.83), or roads with on-road bicycle lanes (OR=1.34, 95% CI: 1.03, 1.75). Conclusions. Consistent with gender differences in risk aversion, female commuter cyclists preferred to use routes with maximum separation from motorized traffic. Improved cycling infrastructure in the form of bicycle paths and lanes that provide a high degree of separation from motor traffic is likely to be important for increasing transportation cycling amongst under-represented population groups such as women.https://www.ncbi.nlm.nih.gov/pubmed/1769818

Screening children with developmental coordination disorder : the development of the caregiver assessment of movement participation

This study investigated the psychometric properties of the Caregiver Assessment of Movement Participation (CAMP), which was developed to measure and identify children with movement participation problems in home contexts. The test-retest reliability, as well as the concurrent and contrast-group validity of the 35-item parent-proxy CAMP, was examined on 312 children aged 5 to 8 years using intraclass correlation, factor analysis, and the Rasch model. Initial findings on the CAMP appeared to support its validity. Testing on other properties from a practical perspective, such as finding the best rating scale structure and cutpoints, are recommended before using the instrument for child health surveillance screening. <br /

A comparison of four functional test in discriminating fallers from non-fallers in older people

Purpose : Which functional tests on mobility and balance can better screen older people at risk of falls is unclear. This study aims to compare the Berg Balance Scale (BBS), Tinetti Mobility Score (TMS), Elderly Mobility Scale (EMS) and Timed Up and Go test (TUG) in discriminating fallers from non-fallers in older people. Method : This was a case-control study involving one rater who conducted a mobility and balance assessment on subjects using the four functional tests in random sequence. Subjects recruited included 17 and 22 older people with a history of single and multiple falls respectively from a public Falls Clinic, and 39 community-dwellers without fall history and whose age, sex and BMI matched those of the fallers. All subjects underwent the mobility and balance assessment within one day. Results : Single fallers performed better than multiple fallers in all four functional tests but were worse than non-fallers in the BBS, TMS and TUG. The BBS demonstrated the best discriminating ability, with high sensitivity and specificity. The BBS item \u27pick up an object from the floor\u27 was the best at screening fallers. Conclusion : BBS was the most powerful functional test of the four in discriminating fallers from non-faller

Risk of death in dialysis patients taking cisapride

AbstractBackgroundCisapride is a prokinetic agent that is useful to relieve gastrointestinal symptoms that often occur in dialysis patients. However, sudden death has been reported and alarmed the use of cisapride in dialysis patients. This study was performed to identify whether the use of cisapride increases the risk of death.MethodsWe retrospectively analyzed all records of dialysis patients followed during the period November 1997 to March 2000. Cisapride dosage and risk factors associated with increased risk of sudden death such as cardiovascular disease, hypokalemia, and possible interacting drugs were recorded.ResultsOf 364 dialysis patients, 85 had been prescribed with cisapride (group A) whereas 279 had not (group B). Group A patients were older, with more female patients and longer duration of dialysis. There was no significant difference in mortality or causes of death between the two groups after adjusting for the baseline demographic differences. For group A, eight patients (9.41%) died while still on cisapride and 19 (22.4%) died after cisapride had been stopped. The causes of death were peritonitis (n = 2), infection (n = 2), ischemic heart disease (n = 1), malignancy (n = 1), sudden death (n = 1), and unknown (n = 1). Low serum albumin (p=0.013) and hypokalemia (p=0.066) were potential predictors of death while taking cisapride, but the presence of diabetes mellitus, maximum dosage of cisapride, and underlying cardiovascular disease were not. There was no drug interaction leading to cisapride toxicity.ConclusionsPatients who were given cisapride were older, more often women, and had a longer duration of dialysis. Low serum albumin and hypokalemia were significant predictors of death in patients given cisapride. Although no excessive risk of death was documented, the use of cisapride in dialysis patients should still be cautious and potential drug interactions and electrolyte disturbances should be avoided

Optimal stimulation duration of tens in the management of osteoarthritic knee pain

Objective: This study examined the optimal stimulation duration of transcutaneous electrical nerve stimulation (TENS) for relieving osteoarthritic knee pain and the duration (as measured by half-life) of post-stimulation analgesia. Subjects: Thirty-eight patients received either: (i) 20 minutes (TENS20); (ii) 40 minutes (TENS40); (iii) 60 minutes (TENS60) of TENS; or (iv) 60 minutes of placebo TENS (TENSPL) 5 days a week for 2 weeks. Methods: A visual analogue scale recorded the magnitude and pain relief period for up to 10 hours after stimulation. Results: By Day10, a significantly greater cumulative reduction in the visual analogue scale scores was found in the TENS40 (83.40%) and TENS60 (68.37%) groups than in the TENS20 (54.59%) and TENSPL (6.14%) groups (p 3 0.000), such a group difference was maintained in the 2-week followup session (p 3 0.000). In terms of the duration of post-stimulation analgesia period, the duration for the TENS40 (256 minutes) and TENS60 (258 minutes) groups was more prolonged than in the other 2 groups (TENS20 = 168 minutes, TENSPL = 35 minutes) by Day10 (p 3 0.000). However, the TENS40 group produced the longest pain relief period by the follow-up session. Conclusion: 40 minutes is the optimal treatment duration of TENS, in terms of both the magnitude (VAS scores) of pain reduction and the duration of post-stimulation analgesia for knee osetoarthritis.<br /

The Specific Characteristics of Childhood Obesity and the Effective Strategies to Combat Childhood Obesity in Hong Kong: A Short Review

Childhood obesity is a serious public health problem all around the world. The problem also currently exists in Hong Kong. Unhealthy lifestyle behavior may be one of key factors contributing to childhood obesity. The review revealed the specific characteristics of childhood obesity and the effective strategies in prevention of childhood obesity in Hong Kong context. Hong Kong is a metropolitan city which is interwoven eastern and western culture. The historical reasons and the complex political issues lead to overcrowded of people living in a small place. The environmental factors and the lifestyle pattern are the crucial causes contributing to childhood obesity. Parents have significant influence in shaping lifestyle behavior of children. While Chinese culture, informal childcare and more energy-dense food consumptions are the specific factors affecting children in lifestyle behavior as shown in the previous studies. The finding of the present review paper is expected to realize root causes of the prevalence of childhood obesity. On the other hand, many studies regarding to the treatment of childhood obesity were also reviewed. It was found that fewer studies were conducted to provide the combined intervention to combat childhood obesity. Generally, parental education was not the focus of childhood obesity intervention programs and parent-oriented approach was not commonly adopted in these programs. While limited childhood obesity intervention programs have been conducted in Hong Kong, it is recommended to conduct an appropriate program for children specifically in Hong Kong context. The design of preventive strategies should take into consideration of these specific characteristics in Hong Kong to reverse the increased prevalence of childhood obesity

Discordance between lung function of Chinese university students of 20-year-old established norms

Objective: We examined the validity of the 20-year-old established Asian norms for pulmonary function in a contemporary cohort of Hong Kong Chinese university students. Design and participants: Pulmonary function testing was conducted in university students (n = 805). Setting: A university campus in Hong Kong. Measurements and results: Parameters recorded included gender, age, height, weight, standard lung function variables (ie, FEV1, FVC, and peak expiratory flow rate [PEFR]), and exhaled carbon monoxide (CO) level. Subjects completed a questionnaire on pulmonary health, smoking history, and their dietary and exercise habits within 3 months of the study. Data were compared with the established norms for lung function for Chinese persons from Hong Kong. On average, subjects were taller than those reported in the original cohort, on whom the established norms are based; however, FEV1, FVC, and PEFR were lower. As predicted, the exhaled CO level was higher in smokers. Those who exercised regularly had a higher FEV1 and FVC, and reported fewer respiratory complaints. Conclusions: Our findings support the idea that lung function norms not only differ across ethnic groups, but that they may be susceptible to change over a single generation within an ethnic group living in the same geographic region. Assuming the equivalence of our testing methods and those on which established norms are based, our findings shed further insight into the dynamic nature of lung function, and have implications regarding the definition of normal pulmonary function and its variance over the short term. <br /

Blood-nourishing and Hard-softening Capsule Costs Less in the Management of Osteoarthritic Knee Pain: A Randomized Controlled Trial

The blood-nourishing and hard-softening (BNHS) capsule is a traditional Chinese formula used in the symptomatic treatment of inflammation and pain. We conducted this randomized controlled trial to compare the efficacy of BNHS with other commonly prescribed drugs. We recruited 120 patients from two teaching hospitals; 30 patients in each hospital were randomly assigned to receive BNHS. In one hospital, the 30 controls were given another traditional Chinese drug; whereas a Western medicine (chondroprotection drug/Viartril-s) was used as the control in the other hospital. Intervention was carried out over a period of 4 weeks. Primary outcome measures included self-reported pain level, and changes in stiffness and functional ability as measured by the Western Ontario McMaster Universities Osteoarthritis (WOMAC) index. Mixed models were used for statistical analysis. Substantial improvements in disease-specific symptoms were observed, after 4 weeks of treatment, in patients taking BNHS capsules. As assessed by the WOMAC index, pain level of the BNHS group decreased by 57% [95% confidence interval (CI) = 50, 63], stiffness by 63% (95% CI = 55, 71) and functional ability increased by 56% (95% CI = 50, 63). No significant differences were found in any of the outcome measures between the BNHS group and either of the comparison groups. No severe adverse effects were reported. However, this study lacked a placebo group; therefore, we conclude that BNHS appears to be as effective as commonly prescribed medicines for the relief of pain and dysfunction in knee osteoarthritis patients, but costs a lot less than other Western and herbal drugs in the study

Testing a Model of Patient Characteristics, Psychologic Status, and Cognitive Function as Predictors of Self-Care in Persons with Chronic Heart Failure

Objective Self-care is a key component in the management of chronic heart failure (CHF). Yet there are many barriers that interfere with a patient\u27s ability to undertake self-care. The primary aim of the study was to test a conceptual model of determinants of CHF self-care. Specifically, we hypothesized that cognitive function and depressive symptoms would predict CHF self-care. Methods Fifty consecutive patients hospitalized with CHF were assessed for self-care (Self-Care of Heart Failure Index), cognitive function (Mini Mental State Exam), and depressive symptoms (Cardiac Depression Scale) during their index hospital admission. Other factors thought to influence self-care were tested in the model: age, gender, social isolation, self-care confidence, and comorbid illnesses. Multiple regression was used to test the model and to identify significant individual determinants of self-care maintenance and management. Results The model of 7 variables explained 39% (F [7, 42] 3.80; P = .003) of the variance in self-care maintenance and 38% (F [7, 42] 3.73; P = .003) of the variance in self-care management. Only 2 variables contributed significantly to the variance in self-care maintenance: age (P \u3c .01) and moderate-to-severe comorbidity (P \u3c .05). Four variables contributed significantly to the variance in self-care management: gender (P \u3c .05), moderate-to-severe comorbidity (P \u3c .05), depression (P \u3c .05), and self-care confidence (P \u3c .01). When cognitive function was removed from the models, the model explained less of the variance in self-care maintenance (35%) (F [6, 43] 3.91; P = .003) and management (34%) (F [6, 43] 3.71; P = .005). Conclusion Although cognitive function added to the model in predicting both self-care maintenance and management, it was not a significant predictor of CHF self-care compared with other modifiable and nonmodifiable factors. Depression explained only self-care management
