Insomnia during the COVID-19 pandemic: prevalence and correlates in a multi-ethnic population Singapore.

Background: Globally, the Coronavirus disease 2019 (COVID-19) pandemic had a significant impact on mental health. Sudden lifestyle changes, threatening information received through various sources, fear of infection and other stressors led to sleep disturbances such as insomnia. The current study aimed to assess the prevalence of insomnia and its associated risk factors during the first wave of COVID-19 pandemic among Singapore residents.

Factors influencing smoking cessation: Insights from Singapore's nationwide health and lifestyle survey.

Introduction: Singapore has implemented an evidence-based smoking cessation framework to support smokers in quitting. Our study investigated the prevalence and correlates of (1) quit attempts (QA) and quit intentions (QI) among current smokers, and (2) smoking cessation (SC) among ever-smokers in Singapore.

Method: Data was collected from a nationwide survey conducted between 2020 and 2022.

Adherence to COVID-19 measures and the associated factors: evidence from a two-wave longitudinal study in Singapore.

Background: At the onset of the Coronavirus disease (COVID-19) pandemic when pharmaceutical interventions were not readily available, governments relied on public health mandates and social distancing measures to counter rising infection rates. In order to address the dearth of longitudinal studies, this study sought to identify factors associated with continued adherence to COVID-19 preventive behaviours in Singapore.

Methods: Data were from a two-wave longitudinal cohort study; baseline study was conducted from May 2020 to June 2021 and follow-up study from October 2021 to September 2022.

Radical reactivity of antiaromatic Ni(II) norcorroles with azo radical initiators.

Norcorrole is a stable 16π-antiaromatic porphyrinoid that exhibits characteristic reactivities and physical properties. Here, we disclose the reaction of Ni(II) norcorroles with alkyl radicals derived from azo radical initiators. The radical selectively attacked the distal α-position relative to the -position to construct a nonaromatic bowl-shaped structure.

Understanding Major Depressive Disorder in Singapore: Insights from the second Singapore Mental Health Study (SMHS 2016).

Background: Major Depressive Disorder (MDD) poses significant public health challenges globally and in Southeast Asia, with substantial impairment and disease burden. Understanding its prevalence and associated risk factors is crucial for effective intervention.

Methods: This study aims to describe the prevalence shifts, correlates, and comorbidities of MDD in Singapore.
