Tey NP, Lai SL, Teh JK

Maturitas, 2016 Dec;94:39-45.
PMID: 27823743 DOI: 10.1016/j.maturitas.2016.08.016

OBJECTIVES: The aims of this study were to assess the current sharp rise in chronic diseases and disabilities with advancing age, and to examine the debilitating effects of chronic diseases among the oldest old in China.
STUDY DESIGN AND OUTCOME VARIABLES: This study used data from four waves of the Chinese Longitudinal Health and Longevity Survey (CLHLS) conducted in 2002, 2005, 2008 and 2011. The sample comprised 2137 older adults who were interviewed in 2002 and re-interviewed in the following waves. Cross-tabulations were run to show the rise in chronic disease and disability with age. Ordinal logistic regression was run to examine the debilitating effects of these diseases in terms of the ability of the oldest old to perform activities of daily living.
RESULTS: The prevalence of chronic diseases rose sharply with age. The prevalence rate of six major diseases increased between 38% (respiratory diseases) and 533% (neurological disorder) among respondents who were re-interviewed nine years later. Cardiovascular diseases were the most common. Neurological disorder and cancer were less common, but had the most debilitating effects on patients. Overall, 10.0%, 3.1% and 3.1% of the respondents were disabled by cardiovascular, musculoskeletal and sensorial diseases, respectively. Ordinal logistic regression showed that neurological disorder had the strongest debilitating effects, followed by musculoskeletal and cardiovascular diseases among 2137 older persons who had survived and were followed up from the base year (2002) through 2011.
CONCLUSION: The rapid rise in chronic diseases has resulted in an increased burden of disability among the oldest old in China. There is a need to improve health care systems for the prevention and management of chronic diseases.
Productive engagement of older adults in China: A multilevel analysis

Sia BK, Tey NP, Goh KL, Ng ST

Geriatr Gerontol Int, 2021 Dec;21(12):1138-1146.
PMID: 34700364 DOI: 10.1111/ggi.14299

AIM: This study investigates how the personal characteristics and behavior, and health status of older adults in China influenced their productive engagement in paid and unpaid jobs.
METHODS: Data for this analysis came from 2002, 2005, 2008 and 2011 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). We used a random intercept multilevel multinomial logit model to analyze data from 3208 older adults aged 65 from the 2002 wave, which decreased to 1385 in 2011. The main study variable is older adults' engagement in paid jobs and unpaid work (including housework, care-taking, poultry farming, and planting vegetables that have an economic value).
RESULTS: There was a strong association between older adults' productive engagement and their functional limitations to daily living activities, health and healthy behavior. Older adults with inadequate finance were more likely to be working to support themselves. Those who exercised less and living in the provinces with higher GDP were less likely to work post-retirement. Chronic diseases, advances in age, no education and rural residence did not deter older adults from doing unpaid work.
CONCLUSION: Older adults in China were actively engaged in paid and unpaid activities. Efforts to support the active engagement of older adults require all stakeholders to promote healthy living, facilitate social engagements and provide an age-friendly work environment.

Multiethnic Malaysia provides a unique case study of divergence in population aging of different sociocultural subgroups within a country. Malaysia represents 3 major ethnicities in Asia-the Malay, Chinese, and Indian. The 3 ethnic groups are at different stages of population aging, as they have undergone demographic transition at different pace amidst rapid social and economic changes. Between 1991 and 2010, the Malaysian population aged 60 and over has more than doubled from about 1 million to 2.2 million, and this is projected to rise to about 7 million or 17.6% of the projected population of 40 million by 2040. In 2010, the aging index ranged from 22.8% among the Bumiputera (Malays and other indigenous groups), to 31.4% among the Indians and 55.0% among the Chinese. Population aging provides great challenges for Malaysia's social and economic development. The increasing prevalence of noncommunicable diseases in older adults, coupled with the erosion of the traditional family support system has increased demands on health care services with an overwhelming need for multidisciplinary and specialized geriatric care. Following the adoption of the National Policy for the Elderly in 1995, issues of population aging have gained increasing attention, especially among researchers. There is an urgent need to increase public awareness, develop infrastructure, as well as support action oriented research that will directly translate to comprehensive and cohesive social strategies, policies, and legislation to protect not just the current older Malaysians but the future of all Malaysians.
Fulltext Medical students' attitudes toward abortion education: Malaysian perspective

Tey NP, Yew SY, Low WY, Su'ut L, Renjhen P, Huang MS, et al.

PLoS One, 2012;7(12):e52116.
PMID: 23300600 DOI: 10.1371/journal.pone.0052116

Abortion is a serious public health issue, and it poses high risks to the health and life of women. Yet safe abortion services are not readily available because few doctors are trained to provide such services. Many doctors are unaware of laws pertaining to abortion. This article reports survey findings on Malaysian medical students' attitudes toward abortion education and presents a case for including abortion education in medical schools.
Fulltext Ethnic differences in the prevalence, socioeconomic and health related risk factors of knee pain and osteoarthritis symptoms in older Malaysians

Knee pain is often underreported, underestimated and undertreated. This study was conducted to estimate the prevalence, burden and further identify socioeconomic factors influencing ethnic differences in knee pain and symptoms of OA among older adults aged 55 years and over in Greater Kuala Lumpur (the capital city of Malaysia). The sample for the Malaysian Elders Longitudinal Research (MELoR) was selected using stratified random sampling, by age and ethnicity from the electoral rolls of three parliamentary constituencies. Information on knee pain was available in 1226 participants, mean age (SD) 68.96 (1.57) years (409 Malay, 416 Chinese, 401 Indian). The crude and weighted prevalence of knee pain and self-reported knee OA symptoms were 33.3% and 30.8% respectively. There were significant ethnic differences in knee pain (crude prevalence: Malays 44.6%, Chinese 23.5% and Indians 31.9%, p<0.001). The presence of two or more non-communicable diseases (NCD) attenuated the increased risk of knee pain among the ethnic Indians compared to the ethnic Chinese. The prevalence of knee pain remained significantly higher among the ethnic Malays after adjustment for confounders. While the prevalence of knee pain in our older population appears similar to that reported in other published studies in Asia, the higher prevalence among the ethnic Malays has not previously been reported. Further research to determine potential genetic susceptibility to knee pain among the ethnic Malays is recommended.
