Methods This secondary analysis pooled individual participant data from 10 community-based smoking cessation trials conducted in Hong Kong …

Effectiveness of Instant Messaging-Based Online Group Support for Preventing Smoking Relapse: A Pragmatic Randomized Controlled Trial
Online group support potentially help prevent smoking relapse. This two-arm, pragmatic, open-label randomized controlled trial assessed the effectiveness of instant messaging (IM) (i.e., WhatsApp) online group support versus text messages for smoking relapse prevention.

Effectiveness of personalized smoking cessation intervention based on ecological momentary assessment for smokers who prefer unaided quitting: Protocol for a randomized controlled trial
Introduction Ecological momentary assessment (EMA)-based smoking cessation intervention may help personalize intervention for smokers who prefer to quit smoking unaided. This study aims to evaluate the effectiveness of EMA-based phone counseling and instant messaging for smoking cessation. Methods/design This is a two-arm, accessor-blinded, simple individual randomized controlled trial (allocation ratio 1:1). Participants will be recruited from c…
Increase of unmotivated and hardened smokers in Hong Kong: A repeated cross-sectional trend analysis

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. We investigated how Facebook was used against regulations to sell HTPs in HK. We screened Facebook pages run by HTP businesses targeting HK users in June 2019 and included pages with over 300 "Likes" for inductive content analysis by coding their "About" descriptions an…
Self-Reported Screen Time on Social Networking Sites Associated With Problematic Smartphone Use in Chinese Adults: A Population-Based Study
Background: Problematic smartphone use (PSU) has been associated with screen time in general, but little is known about the effect of different screen-based activities. We examined the associations of self-reported time spent on overall and specific screen-based activities with PSU and its addictive symptoms in Hong Kong Chinese adults. Methods: We analyzed data from 562 smartphone owners (56.5% female; 82.1% aged 25–64 years) in a population-bas…
Factors Associated With Mental Health Symptoms During the Covid-19 Pandemic in Hong Kong
Background: The COVID-19 pandemic has led to an increasing mental health burden. We examined the factors associated with mental health symptoms in Chinese general adults in Hong Kong. Methods: We conducted a dual-frame (landline and mobile) survey on Chinese adults aged 18 years or older in April 2020. Shortage of preventive materials, perceptions of the outbreak (each item range 1-5), and reduction in income were assessed. Mental health symptoms…
High Perceived Susceptibility to and Severity of Covid-19 in Smokers Are Associated with Quitting-Related Behaviors
A growing body of evidence shows smoking is a risk factor for coronavirus disease (COVID-19). We examined the associations of quitting-related behaviors with perceived susceptibility to and severity of COVID-19 in smokers. We conducted a telephone survey of 659 community-based adult smokers (81.7% male) in Hong Kong, where there was no lockdown. Exposure variables were perceptions that smoking can increase the risk of contracting COVID-19 (percei…
Problematic Smartphone Use and Mental Health in Chinese Adults: A Population-Based Study
Problematic smartphone use (PSU) has been associated with anxiety and depression, but few explored its mental well-being correlates that could co-occur with or be independent of mental symptoms. We studied the associations of PSU with anxiety, depression, and mental well-being in Hong Kong Chinese adults in a probability-based survey ( N = 4054; 55.0% females; mean age ± SD 48.3 ± 18.3 years). PSU was measured using Smartphone Addiction Scale-Sho…
Exposure to health misinformation about Covid-19 and increased tobacco and alcohol use: A population-based survey in Hong Kong
Our results first showed that exposure to health misinformation that smoking/alcohol drinking can protect against COVID-19 was associated with self-reported increases in tobacco and alcohol consumption in Chinese during the pandemic
Association of heated tobacco product use with smoking cessation in Chinese cigarette smokers in Hong Kong: A prospective study
HTP use was not associated with cigarette abstinence at 6 months in a community-based cohort of smokers with intentions to quit or reduce smoking. Trial registration details ClinicalTrials.gov, NCT03565796
The reliability and validity of the Chinese Short Warwick-Edinburgh Mental Well-being Scale in the general population of Hong Kong
Short version of the Smartphone Addiction Scale in Chinese adults: Psychometric properties, sociodemographic, and health behavioral correlates
Background and aims Problematic smartphone use (PSU) is an emerging but understudied public health issue. Little is known about the epidemiology of PSU at the population level. We evaluated the psychometric properties of the Smartphone Addiction Scale – Short Version (SAS-SV) and examined its associated sociodemographic factors and health behaviors in Chinese adults in Hong Kong. Methods A random sample of 3,211 adults aged ≥18 years (mean ± SD :…
