Frequency and accuracy of weight comments by others, and the association with weight misperception among Hong Kong adolescents
*Purpose:* To assess the frequency and accuracy of weight comments received from different sources among Chinese adolescents and the relation of weight comments to weight misperception.

*Methods:* In the Hong Kong Student Obesity Surveillance (HKSOS) project 2006-07, 22612 form 1 to 7 students (41.5% boys) completed a questionnaire on obesity. Students were asked if they had received serious "too fat" or "too thin" comments over the past 30 days from family members, peers and professionals, and the accuracy of the comments was assessed against the actual weight status. Weight misperception was defined as discordance between the actual and perceived weight status. Logistic regression was used to calculate adjusted odd ratios (ORs) for weight misperception by weight comments received.

*Results:* One in three students received weight comments, most commonly from mother for both "too fat" and "too thin" comments. Health professional was the most accurate source of weight comments, yet less than half the comments were correct. Receiving incorrect weight comments was significantly associated with weight misperception in all sex-weight status sub-groups, particularly among obese girls. In contrast, student who received correct weight comments were less likely to have weight misperception.

*Conclusions:* Weight comments were commonly received by Chinese adolescents in Hong Kong, yet most of the comments were inaccurate, and such incorrect comments were associated with weight misperception. Family members, peers and professionals should realize the potential adverse effects of their weight comments and adolescents should be taught how to correctly assess their weight status to reduce misperceptions

Moderate Alcohol Use and Mortality from Ischaemic Heart Disease: A Prospective Study in Older Chinese People
Abstract Background: Moderate alcohol use is generally associated with lower ischaemic heart disease (IHD) mortality but it is difficult to ascertain whether this is due to attributes of moderate alcohol users or the properties of alcohol itself. Evidence from populations with different patterns of alcohol use and IHD can provide crucial evidence. We assessed the association of moderate alcohol use with IHD mortality in older Chinese people from Hong Kong.
Methodology We used Cox regression to determine whether moderate alcohol use was associated with IHD mortality in a prospective, population-based cohort study of all 56167 attendees, aged 65 years or over, from July 1998 to December 2000 at all 18 Elderly Health Centers operated by the Department of Health in Hong Kong.
Principal Findings After a median follow-up of 4.2 years, there were 406 (188 in men, 218 in women) deaths from IHD in 54,090 subjects (96.3% successful follow-up). Moderate alcohol use in men was not associated with IHD mortality adjusted only for age [Hazard Ratio, HR 1.01 (95% CI 0.55 to 1.84) compared with never drinkers] or additionally adjusted for socioeconomic status and lifestyle. Almost all women were occasional drinkers and their current alcohol use was not significantly associated with IHD mortality [HR 0.88, (95% CI 0.51 to 1.53)].
Conclusions Moderate alcohol use had no effect on IHD mortality in older Chinese men. Lack of replication of the usual protective effect of moderate alcohol use in a setting with a different pattern of alcohol use and IHD could be due to chance or could suggest that the protective effect of alcohol on IHD does not extend to all populations
Examining consumers’ adoption of wearable healthcare technology: The role of health attributes
With the advancement of information technology, wearable healthcare technology has emerged as one of the promising technologies to improve the wellbeing of individuals. However, the adoption of wearable healthcare technology has lagged when compared to other well-established durable technology products, such as smartphones and tablets, because of the inadequate knowledge of the antecedents of adoption intention. The aim of this paper is to address an identified gap in the literature by empirically testing a theoretical model for examining the impact of consumers’ health beliefs, health information accuracy, and the privacy protection of wearable healthcare technology on perceived usefulness. Importantly, this study also examines the influences of perceived usefulness, consumer innovativeness, and reference group influence on the adoption intention of wearable healthcare technology. The model seeks to enhance understanding of the influential factors in adopting wearable healthcare technology. Finally, suggestions for future research for the empirical investigation of the model are provided

The Association of Problematic Smartphone Use with Family Well-Being Mediated by Family Communication in Chinese Adults: A Population-Based Study
Background and aims: Few studies have investigated the effects of problematic smartphone use (PSU) in the family context. We studied the association of PSU as a predictor with family well-being and the potential mediating role of family communication in Hong Kong Chinese adults. Methods: We analyzed data of 5,063 randomly selected adults [mean age (SD) = 48.1 (18.2) years; 45.0% men] from a dual landline and mobile telephone survey in 2017. PSU was assessed by the Smartphone Addiction Scale-Short Version with higher scores indicating higher levels. Family well-being was assessed by three questions on perceived family health, harmony, and happiness (3Hs) with higher scores indicating greater well-being. Perceived sufficiency and quality of family communication were rated. Multivariable regression analyses examined (a) associations of PSU with family 3Hs and well-being and (b) mediating role of family communication, adjusting for sociodemographic variables. Results: PSU was negatively associated with perceived family health (adjusted β = −0.008, 95% CI = −0.016, −0.0004), harmony (adjusted β =−0.009, 95% CI = −0.017, −0.002), happiness (adjusted β =−0.015, 95% CI = −0.022, −0.007), and well-being (adjusted β= −0.011, 95% CI = −0.018, −0.004). Perceived family communication sufficiency (adjusted β = −0.007, 95% CI =−0.010, −0.005) and quality (adjusted β = −0.009, 95% CI =−0.014, −0.005) mediated the association of PSU with family well-being, with 75% and 94% of total effects having mediated, respectively. Discussion and conclusions: PSU was negatively associated with family well-being, which was partially mediated by family communication. Such findings provide insights for health programs to prevent PSU and improve family well-being
Estimating daily and diurnal variations of illicit drug use in Hong Kong: A pilot study of using wastewater analysis in an Asian metropolitan city
The measurement of illicit drug metabolites in raw wastewater is increasingly being adopted as an approach to objectively monitor population-level drug use, and is an effective complement to traditional epidemiological methods. As such, it has been widely applied in western countries. In this study, we utilised this approach to assess drug use patterns over nine days during April 2011 in Hong Kong. Raw wastewater samples were collected from the largest wastewater treatment plant serving a community of approximately 3.5 million people and analysed for excreted drug residues including cocaine, ketamine, methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA) and key metabolites using liquid chromatography coupled with tandem mass spectrometry. The overall drug use pattern determined by wastewater analysis was consistent with that have seen amongst people coming into contact with services in relation to substance use; among our target drugs, ketamine (estimated consumption: 1400-1600. mg/day/1000 people) was the predominant drug followed by methamphetamine (180-200. mg/day/1000 people), cocaine (160-180. mg/day/1000 people) and MDMA (not detected). The levels of these drugs were relatively steady throughout the monitoring period. Analysing samples at higher temporal resolution provided data on diurnal variations of drug residue loads. Elevated ratios of cocaine to benzoylecgonine were identified unexpectedly in three samples during the evening and night, providing evidence for potential dumping events of cocaine. This study provides the first application of wastewater analysis to quantitatively evaluate daily drug use in an Asian metropolitan community. Our data reinforces the benefit of wastewater monitoring to health and law enforcement authorities for strategic planning and evaluation of drug intervention strategies
