Smokefree home rules and susceptibility to cigarette and e-cigarette use in adolescents
SFH rules, especially strict rules without violations, were associated with lower susceptibility to cigarette or EC use, and this association was partly mediated through less tolerant attitudes toward tobacco use. Further research on policies and interventions on SFH rules and practice is warranted for effective tobacco prevention
Association between sarcopenic obesity, obesity, sarcopenia and quality of life in middle-aged and older Chinese

A population-based cross-sectional online survey was conducted in May 2020 on Hong Kong adults (N …
Late-onset or chronic overweight/obesity predicts low self-esteem in early adolescence
Late-onset or chronic overweight/obesity predicted low general, social and academic/school-related self-esteem. Children who successfully reduced weight may have equal levels of self-esteem or even better social self-esteem than those being always underweight/normal weight. Overweight/obese children had a vulnerability to self-esteem in non-domestic environments
Obesity indicators as mediators of association between daytime napping and type 2 diabetes mellitus
Our results showed significant mediating effects of WC, WHR and WHtR on the association between daytime napping and T2DM, suggesting that waist circumference management could be important in daytime nappers
Perception of heated tobacco products and support for regulations
Lower support for HTP regulations and a total ban on sale were associated with perceptions of reduced harm and effectiveness for quitting CCs of HTPs in Hong Kong
A content analysis of heated tobacco product business in Hong Kong on Facebook
Heated tobacco products (HTPs) are increasingly popular in Hong Kong (HK) even though they have not been formally launched and the sale of duty-not-paid tobacco sticks is illegal.

Suicidality and cultural values among Hong Kong adolescents
Are height and leg length universal markers of childhood conditions? The Guangzhou Biobank cohort study
OBJECTIVE: In developed western populations longer legs have been shown to be a marker of better early childhood conditions. In the first generations to experience the epidemiologic transition and associated economic development, epigenetic constraints on growth might preclude improved childhood conditions from increasing leg growth or height. DESIGN, SETTING AND PARTICIPANTS: Multivariable linear regression was used to assess the association of …

A Comparison of Three Retrospective Self-reporting Methods of Measuring Change in Instructional Practice
Inequality and inequity in access to health care and treatment for chronic conditions in China
Non-communicable diseases (NCDs) are a large and rapidly-growing problem in China and other middle-income countries. Clinical treatment of NCDs is long-term and expensive, so it may present particular problems for equality and horizontal equity (equal treatment for equal need) in access to health care, although little is known about this at present in low- and middle-income countries. To address this gap, and inform policy for a substantial propo…
Is leg length a biomarker of childhood conditions in older Chinese women? The Guangzhou Biobank Cohort Study
OBJECTIVE: In developed western populations longer legs have been shown to be a biomarker of better early childhood conditions. It was hypothesised that in transitioning populations better childhood conditions may bring forward puberty and thus decrease leg length, counteracting the overall positive effect of a favourable childhood environment on leg growth. DESIGN: Structural equation modelling was used to assess the interrelationship of age, ed…

Children in the experimental group experienced greater happiness, fewer worries and lesser difficulty in psychological adjustment than children in the control group, providing evidence that the play-integrated prepara…
Liver enzymes and incident diabetes in China
BACKGROUND: Impaired liver function has been shown to be associated with incident diabetes. The independent role of the different liver enzymes, including γ-glutamyltransferase (GGT), alanine transaminase (ALT) and aspartate transaminase (AST), has not been addressed properly, taking into account their high collinearity. We used partial least squares (PLS) regression to identify the contribution of ALT, AST and GGT, which appears causally associa…
Smoking cessation and carotid atherosclerosis
INTRODUCTION: Smoking has been shown to be associated with carotid atherosclerosis in cross-sectional and prospective studies in Western populations. However, few studies have examined the reversal of risk resulting from quitting smoking, and the results are conflicting. METHODS: 959 men aged 50-85 years were randomly selected from phase III (2006-2007) of the Guangzhou Biobank Cohort Study into this cross-sectional study. Common carotid artery i…
Alcohol use and fasting glucose in a developing southern Chinese population
BACKGROUND: In observational studies, mainly from Western Caucasian populations, moderate alcohol use has been shown to be associated with a lower risk of diabetes. However, whether the protection is due to the attributes of alcohol or to those of moderate alcohol users is difficult to disentangle. A population with a different distribution of alcohol consumption and diabetes prevalence from Western populations was studied as a counterfactual com…
