Study protocol for a comparative randomized controlled trial of Tai Chi and conventional exercise training on alleviating depression in older insomniacs.

Background: Insomnia and depression are prevalent mental disorders that are often comorbid among older adults. Lifestyle intervention strategies incorporating Tai Chi or conventional exercise have been shown to alleviate symptoms of insomnia and depression. However, the comparative efficacy of these exercise modalities in individuals with both disorders has yet to be determined.

Psychosocial factors of stages of change among adults with intellectual disabilities.

Relationships among full constructs of the transtheoretical model using a sample of 121 adults with mild intellectual disabilities in Taiwan were examined. Self-reports of stages of change and transtheoretical model psychosocial measures were gathered through interviews. Although MANCOVA revealed that behavioral processes of change, cognitive processes of change, self-efficacy, and perceived pros increased across stages, we did not find a clear linear pattern of association.

Association between physical activity and cardiovascular risk in Chinese youth independent of age and pubertal stage.

Background: Childhood and adolescence are critical periods of habit formation with substantial tracking of lifestyle and cardiovascular risk into adulthood. There are various guidelines on recommended levels of physical activity in youth of school-age. Despite the epidemic of obesity and diabetes in China, there is a paucity of data in this regard in Chinese youth.

Associations between dietary habits and risk factors for cardiovascular diseases in a Hong Kong Chinese working population--the "Better Health for Better Hong Kong" (BHBHK) health promotion campaign.

Diet and nutritional status have been shown to play pivotal roles in the occurrence of many chronic diseases. In this study, we examined the patterns of dietary habits and their relationships with risk factors for cardiovascular and chronic diseases in Hong Kong working populations. In April 2000, a 5-year territory-wide health promotion campaign supported by the Li Ka Shing Foundation was launched in Hong Kong by the Health InfoWorld of Hospital Authority.

Low levels of awareness of suboptimal health conditions in a high-risk working population: the "better health for better Hong Kong" health promotion campaign.

The incidences of cardiovascular risk factors such as obesity and diabetes are rising in many Asian populations. In April 2000, a 5-year territory-wide health promotion campaign supported by Li Ka Shing Foundation was launched in Hong Kong by the Health InfoWorld of Hospital Authority. From the general working class, 4,832 Chinese people were randomly recruited into this campaign.

Effect of age and gender on energy expenditure in common activities of daily living in a Chinese population.

Purpose: It is important to quantify the amount of energy expended in various common household tasks to provide objective information regarding physical activity recommendations in health promotion, weight management, or rehabilitation programs for older people with chronic diseases. These activities may be age/gender sensitive and culturally specific, and not included in current Compendium of Metabolic Equivalent (MET) values. This study measures the energy expenditure of commonly performed activities of daily living tasks in a Chinese population, examining age and gender differences.

Age-related anthropometric remodelling resulting in increased and redistributed adiposity is associated with increases in the prevalence of cardiovascular risk factors in Chinese subjects.

Background: Ageing promotes increases in the prevalence of components of the metabolic syndrome, which obesity often underlies.

Methods: We report the relationship between ageing, obesity and other cardiovascular risk factors in 694 community-based Chinese subjects in gender-specific groups of three age ranges: 20.0-39.
