Concordance and Discordance of Self-Rated and Researcher-Measured Successful Aging: Subtypes and Associated Factors.

Objectives: To investigate subtypes of successful aging (SA) based on concordance and discordance between self-rated and researcher-defined measures and their associations with demographic, psychosocial, and life satisfaction factors.

Method: We used multinomial logistic regression models to analyze 2013 cross-sectional survey data from 1,962 persons aged 65 and older in Shanghai that measured self-rated successful aging (SSA) with a single global assessment and researcher-defined successful aging (RSA) with a cumulative deficit index reflecting physical, physiological, cognitive, psychological, and social engagement domains. We generated four subtypes based on these two dichotomous variables: nonsuccessful aging (non-SA; meeting neither the criterion of RSA nor the criterion of SSA), RSA-only (meeting the criterion of RSA-only but not the criterion of SSA), SSA-only (meeting the criterion of SSA-only but not the criterion of RSA), and both-successful aging (both-SA; meeting both criteria of RSA and SSA).

Leisure participation and subjective well-being: Exploring gender differences among elderly in Shanghai, China.

Objectives: To explore the association between leisure participation and subjective well-being and the role gender in this issue among elderly Chinese in Shanghai, China.

Methods: Principal components analysis and logistic regressions are used to analyze the cross-sectional data of the 2013 Shanghai Elderly Life and Opinion Survey that contains 2884 respondents (60+ with a mean age of 72.6) recruited from a multistage cluster sampling design.

Validating a Scale of Health Beliefs in Preventive Health Screenings Among Chinese Older Adults.

We aimed to examine the psychometric properties of a modified 16-item Attitudinal Index (AI), a measure of Chinese older adults' beliefs about preventive health screenings. We used the 2013 Shanghai Elderly Life and Opinion data including 3,418 respondents age 60+ who were randomly split into training and validation samples. We examined the validity and reliability of the modified AI.

Social Engagement and Health: Findings From the 2013 Survey of the Shanghai Elderly Life and Opinion.

What are the social factors that matter most to the health of elderly Chinese? Are there any gender and age differences? Using a representative sample of elderly Chinese in Shanghai, the most developed city in China with the nation's largest proportion of elderly residents, this study found that economic conditions, chronic health status, living arrangements, social activity participation, and caring for grandchildren are factors that are most important to the health of elderly Chinese. This is true for both self-rated health and psychological well-being. The beneficial effects of participation in social activities are particularly salient for elderly women and for the old-old, whereas the salutary effects of caring for grandchildren are more substantial for elderly men and for the young-old.

Self-Rated Health, Interviewer-Rated Health, and Their Predictive Powers on Mortality in Old Age.

Objectives: This study examines the potential use of interviewer-rated health (IRH) as a complementary measure of self-rated health (SRH) through a systematic comparison of their components and mortality-predictive powers in the Chinese elderly population.

Methods: This study used a nationwide dataset with more than 12,000 adults aged 65 or older drawn from the 2005 and 2008 waves of the Chinese Longitudinal Health Longevity Survey (CLHLS).

Results: Disability, cognitive function, chronic disease conditions, psychological well-being, and health behaviors influenced both the SRH and IRH of Chinese older adults; these factors, especially disabilities, explained a large portion of the association between SRH and mortality.

Trends in ADL and IADL disability in community-dwelling older adults in Shanghai, China, 1998-2008.

Objectives: We investigated trends in activities of daily living (ADL) and instrumental activities of daily living (IADL) disability from 1998 to 2008 among elder adults in Shanghai, China.

Method: Our data came from 4 waves of the Shanghai Longitudinal Survey of Elderly Life and Opinion (1998, 2003, 2005, and 2008). ADL and IADL disabilities were recorded dichotomously (difficulty vs.

Less exercise and more TV: leisure-time physical activity trends of Shanghai elders, 1998-2008.

Background: Surveillance of physical activity trends in older adults is limited in developing nations. This study examined 10-year leisure-time physical activity trends of elderly residents of Shanghai, the largest Chinese city with the nation's highest proportion of senior citizens.

Methods: The study used panel data from the Shanghai Longitudinal Survey of Elderly Life and Opinion (1998, 2003, 2005 and 2008).

Expression of MTLC gene in gastric carcinoma.

Aim: To investigate the expression of c-myc target from laryngeal cancer cells (MTLC) gene in gastric carcinoma (GC) tissues and the effect of MTLC over-expression on gastric carcinoma cell line BGC823.

Methods: RT-PCR was performed to determine the expression of MTLC mRNA in GC and matched control tissues. BGC823 cells were transfected with an expression vector pcDNA3.
