RESUMEN
Studies demonstrated increased obstetric and neonatal complications in women with schizophrenia-spectrum disorder (SSD), but most inadequately addressed confounders and rarely considered antipsychotic effects. We conducted a meta-analysis and a population-based cohort study evaluating associations of adverse obstetric/neonatal outcomes with SSD and prenatal antipsychotic use. In the meta-analysis, we searched four databases from inception to October-31-2023 and generated pooled risk estimates using random-effect models. In the cohort study, we identified women aged 15-50 years with SSD-diagnosis from electronic-heath-record database of public healthcare-services who delivered first/singleton children between 2003 and 2018 in Hong Kong. Propensity-score weighted regression-analyses incorporating important confounders including maternal pre-existing and gestational morbidities, substance/alcohol abuse, and psychotropic use, were performed to assess risk of adverse obstetric/neonatal outcomes in SSD-women versus non-SSD-women, and subsequently treated-SSD and untreated-SSD subgroups to disentangle effects of SSD from antipsychotic exposure. The meta-analysis (studies = 18, women = 37,214,330, including 42,926 SSD-women) found significant associations of SSD with 12 of 17 analyzed negative obstetric/neonatal outcomes (with pooled relative risk ranged:1.12-2.10), including placental complications, induced labor, Caesarean delivery, fetal distress, stillbirth, preterm birth, small-for-gestational-age, low birth weight, low APGAR scores, neonatal and post-neonatal deaths. However, the cohort study (466,358 women, including 804 SSD-women) revealed that elevated risk of most study outcomes in unadjusted-models were markedly-attenuated or became non-significant in propensity-score weighted adjusted-models, except index-delivery hospitalization ≥7 days (odds ratio [OR] = 1.76 [95% CI = 1.33-2.34]), preterm birth (OR = 1.48 [95% CI = 1.09-2.00]) and neonatal special-care admission (OR = 1.65 [95% CI = 1.35-2.01]). Apart from higher neonatal special-care admission in treated-SSD than untreated-SSD women (OR = 1.75 [95% CI = 1.23-2.52]), no significant between-group differences emerged in other outcomes. In sum, elevated risk of most obstetric/neonatal complications reported in SSD-women might largely be explained by maternal physical comorbidities, substance/alcohol use disorders and other confounders. Interventions targeting modifiable maternal risk factors should be incorporated in prenatal care for SSD-women to minimize avoidable adverse outcomes.
RESUMEN
Pre-exposure prophylaxis (PrEP) use has been shown to be effective for HIV prevention in men who have sex with men (MSM). PrEP use coverage aside, maintenance of high PrEP adherence is crucial in ensuring the achievement of HIV prevention. In this PrEP implementation study in Hong Kong, we examined the patterns of PrEP use in MSM and evaluated their association with prevention-effective adherence for HIV prevention. In January 2020-June 2021 in Hong Kong, 312 recruited MSM (median 30 years old) were followed up for 1 year, with HIV and creatinine testing, consultation, and PrEP refill. No HIV breakthrough infection was observed. As a measure of prevention-effective adherence, executed adherence (EA) was expressed as the proportion of days with HIV risk that were protected by PrEP and/or condom in 6 months. In 65,585 diary entries of 215 MSM, the median proportion of EA achieved was 89% (IQR 84-93%). Three latent classes of PrEP users were identified by latent class analysis. Taking Class 1 "daily dominant PrEP" (n = 113, 53%) as reference, Class 2 "episodic PrEP" (n = 76, 35%) was adopted by MSM with less sexual activity, had less PrEP refill and lower EA level, while Class 3 "mixed PrEP schedule" (n = 26, 12%) MSM were more sexually active but with a similar EA level. The study findings showed varied and dynamic PrEP usage patterns in the real-world setting. Strategies for promoting adherence are needed to ensure the maintenance of high EA level among PrEP-using MSM especially those on episodic PrEP schedule.

PURPOSE: To detect otherwise undiagnosed asymptomatic sexually transmitted infection (STI), and for estimating prevalence among men who have sex with men (MSM). METHODS: In this community-based study in Hong Kong, adult MSM were recruited. After completion of an online survey, free multi-anatomic sites self-sampling kits (urine specimens, pharyngeal and rectal swabs) for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) tests were delivered to requesting participants. Factors associated with STI positivity were analyzed in logistic regression. RESULTS: From September 2021 to October 2022, 712 MSM were recruited, with 86% aged 18-39, and 16% reported history of chemsex engagement. A majority (81%) had previously undergone HIV testing, 68% had ever tested for STI, and 35% previously diagnosed with STI. Totally 428 (60%) had requested self-sampling kits, and 276 (39%) returned collected samples. Among participants who returned the samples, about half had never been tested in the past and had no history of STI. Overall 21% tested positive for CT and/or NG (CT/NG)-CT positive 16% and NG positive 7%. By anatomic site, 16% of rectal swabs, 7% of pharyngeal swabs, but just 3% of urine specimens were CT/NG positive. The prevalence of CT/NG was not significantly different by history of STI diagnosis and testing. CONCLUSION: Self-sampled STI testing is a potentially useful means for enhancing uptake of screening in MSM in the community, which could uncover otherwise undiagnosed asymptomatic infections. Internet-based self-sampling for STI testing could complement the current clinic-based STI testing for supporting epidemiologic evaluation of STI control in the community.

BACKGROUND: Psychiatric patients are susceptible to adverse mental health impacts during COVID-19, but complex interplays between psychopathology and pandemic-related variables remain elusive. This study aimed to investigate concomitant associations between psychopathological symptoms, psychological measures and COVID-19 related variables in Chinese psychiatric patients during the peak of fifth pandemic wave in Hong Kong. METHODS: We employed network analysis to investigate inter-relationships among psychopathological symptoms (including depression, anxiety, post-traumatic stress disorder-like [PTSD-like] symptoms, insomnia, psychotic symptoms), cognitive complaints, health-related quality of life, loneliness, resilience and selected pandemic-related factors in 415 psychiatric outpatients between 28 March and 8 April, 2022. Network comparisons between genders, diagnosis (common mental disorders [CMD] vs. severe mental disorders [SMD]), and history of contracting COVID-19 at fifth wave were performed as exploratory analyses. RESULTS: Our results showed that anxiety represented the most central node in the network, as indicated by its highest node strength and expected influence, followed by depression and quality of life. Three comparatively strong connections between COVID-19 and psychopathological variables were observed including: fear of contagion and PTSD-like symptoms, COVID-19 stressor burden and PTSD-like symptoms, and COVID-19 stressor burden and insomnia. Network comparison tests revealed significant network structural difference between participants with history of contracting COVID-19 and those without, but showed no significant difference between genders as well as between CMD and SMD patients. CONCLUSIONS: Our findings suggest the pivotal role of anxiety in psychopathology network of psychiatric patients amidst COVID-19. Pandemic-related variables are critically associated with trauma/stress and insomnia symptoms. Future research is required to elucidate potential network structural changes between pandemic and post-COVID periods.

BACKGROUND: Psychiatric patients are susceptible to adverse mental health outcome during COVID-19 pandemic, but its associated factors are understudied. This observational cross-sectional study aimed to comprehensively examine prevalence and correlates of psychological distress, in terms of depression, anxiety and post-traumatic-stress-disorder (PTSD)-like symptoms, among Chinese adult psychiatric outpatients amidst the peak of fifth COVID-19 wave in Hong-Kong. METHODS: A total of 415 patients (comprising 246 patients with common-mental-disorders [CMD] and 169 with severe-mental-disorders [SMD]) and 399 demographically-matched controls without mental disorders were assessed with self-rated questionnaires between 28-March and 8-April-2022, encompassing illness profile, mental health symptoms, psychosocial measures (loneliness, resilience, coping styles) and COVID-19 related factors. Univariate and multivariable logistic regression analyses were conducted to determine variables associated with moderate-to-severe depressive, anxiety and PTSD-like symptoms among psychiatric patients. RESULTS: Our results showed that CMD patients had the greatest psychological distress relative to SMD patients and controls. Approximately 40-55% CMD patients and 25% SMD patients exhibited moderate-to-severe depression, anxiety and PTSD-like symptoms. Multivariable regression analyses revealed that female gender, lower educational attainment, single marital status, being housewife, more severe insomnia, psychotic-like symptoms and cognitive complaints, self-harm behavior, lower resilience, avoidance coping, never contracting COVID-19 infection, greater fear of contagion, and longer exposure to pandemic-related information were independently associated with depression, anxiety and/or PTSD-like symptoms in psychiatric patients. CONCLUSIONS: Our results affirm increased vulnerability of psychiatric patients toward psychological distress during pandemic. An array of identified correlates facilitates early detection of high-risk psychiatric patients for targeted strategies to minimize pandemic-related negative psychological impact.

OBJECTIVE: Existing data on prenatal antidepressant prescribing patterns are mostly derived from Western countries, with limited research assessing antidepressant continuation and reinitiation during pregnancy. This study aimed to examine antidepressant prescribing practice among Chinese pregnant women in Hong Kong. METHODS: This population-based study identified women aged 15-50 years who delivered their first and singleton child, and had redeemed at least one antidepressant prescription within 3 months pre-pregnancy and/or during pregnancy between 2003 and 2018, using data from the health-record database of Hong Kong public healthcare services. Antidepressant utilization patterns before and during pregnancy, and factors associated with antidepressant continuation and reinitiation following medication discontinuation were evaluated. RESULTS: Of 466,358 pregnancies, 3019 (0.67%) received antidepressants within 3 months of pre-pregnancy and/or during pregnancy, and 2700 (0.58%) had prenatal antidepressant use. There was a significant rising trend of prenatal antidepressant use over time (0.6% in 2003 to 1.3% in 2018; odds ratio: 1.09, 95% confidence interval = [1.08, 1.10], p < 0.001). A consistent pattern of decreasing overall antidepressant use from 3 months pre-pregnancy to the second trimester was observed, followed by a slight increase in the third trimester. Almost half (n = 949, 49.5%) of 1918 women on antidepressants in 3 months pre-pregnancy continued treatment beyond the first trimester. A total of 8.2% that discontinued antidepressants in 3 months pre-pregnancy or in the first trimester reinitiated treatment in the later stage of pregnancy. Older age at conception (⩾35 years), recent calendar year of delivery (2015-2018), pre-existing depression/anxiety disorders, longer-term pre-pregnancy antidepressant treatment and pre-pregnancy prescription of other psychotropics were significantly associated with antidepressant continuation. Antidepressant reinitiation was predicted by pre-existing depression/anxiety disorders. CONCLUSIONS: Our results that prenatal antidepressant use is increasingly prevalent and half of pregnant women discontinued antidepressants 3 months before or after conception underscore the need for future research to clarify the risk and benefit of antidepressant continuation versus discontinuation to facilitate development of evidence-based guidelines, so as to optimize maternal and fetal outcomes.

Background: Psychotropic substance use, for chemsex in particular, is common in gay or bisexual men (GBM) with HIV infection. This case-control study examined the association between Axis I psychiatric disorders and active psychotropic substance use, and identified factors affecting the prevalence of psychiatric disorders in HIV-infected GBM. Methods: Participants were 62 HIV-infected self-identified GBM who reported psychotropic substance use in the past 1 year (cases), and 55 HIV-infected self-identified GBM without psychotropic substance use in the past 1 year and had negative toxicology tests at recruitment (controls). The Chinese-bilingual Structured Clinical Interview for DSM-IV (Axis I, Patient version) was followed to establish the psychiatric diagnoses. Socio-demographic data, level of social support, HIV-related data, and pattern of psychotropic substance use were collected. Results: Cases had lower level of social support, more depressive disorders (AOR 3.4, 95% CI 1.3-8.7, p=0.01) and psychotic disorders (AOR 7.2, 95% CI 1.2-41, p=0.03) but not anxiety disorders. Significant difference in the prevalence of psychiatric disorders was only evident for disorders with onset after HIV diagnosis. Methamphetamine dependence, weekly methamphetamine use for 2 years or more, using methamphetamine beyond chemsex, duration of HIV diagnosis were significant predictors for psychiatric disorders in the cases. Conclusion: Active psychotropic substance use in HIV-infected gay or bisexual men was associated with an overall 3-fold increase in Axis I psychiatric disorders. Coordinated efforts from HIV, psychiatric and substance use services are needed to prevent harms arising from chemsex and to identify those in need and facilitate treatment access.

Previous studies examining antidepressants and congenital-malformations were primarily conducted in western countries, and many were constrained by important methodological limitations. This population-based study identified 465,069 women (including 1,705 redeemed ≥1 prescription of antidepressants during first-trimester) aged 15-50 years who delivered their first and singleton child between 2003 and 2018 in a predominantly-Chinese population in Hong Kong, using territory-wide medical-record database of public-healthcare services, and employed propensity-score fine-stratification-weighted logistic-regression analyses to evaluate risk of any major and organ/system-specific congenital-malformations following first-trimester exposure to antidepressants. Major malformation overall was not associated with any antidepressant (weighted-odds-ratio wOR, 0.88 [95 %CI, 0.44-1.76]), specific drug-class, or individual antidepressants. Exposure to any antidepressant was associated with increased risk of cardiac (wOR, 1.82 [95 %CI, 1.07-3.12]) and respiratory anomalies (wOR,4.11 [95 %CI, 1.61-10.45]). Exposure to selective-serotonin-reuptake-inhibitors (SSRI) and multiple-AD-classes were associated with respiratory and cardiac anomalies, respectively. However, these identified associations were not consistently affirmed across sensitivity analyses, precluding firm conclusion. Observed associations of specific cardiac defects with serotonin-norepinephrine-reuptake-inhibitors (SNRI), tricyclic-antidepressants (TCA) and multiple-AD-classes were noted with wide confidence-intervals, suggesting imprecise estimation. Overall, our findings suggest that first-trimester antidepressant exposure was not robustly associated with increased risk of congenital-malformations. Further research clarifying comparative safety of individual antidepressants on specific malformations is warranted.

Previous research examining bipolar-disorder (BD) and pregnancy/neonatal outcomes yielded mixed results, were mostly derived from Western countries and rarely delineated effect between disorder and mood-stabilizers. This population-based study identified women age 15-50 years who delivered first/singleton child in 2003-2018 in Hong Kong, utilizing territory-wide medical-record database of public healthcare services. Propensity-score weighted logistic-regression analyses adjusted for confounders were employed to examine risk of adverse pregnancy, delivery and neonatal outcomes associated with BD and mood-stabilizers (lithium, anticonvulsants and antipsychotics). Exploratory unadjusted-analyses were conducted to assess risk for congenital-malformations. Of 465,069 women, 302 had BD-diagnosis, including 168 redeemed ≥ 1 prescription of mood-stabilizers during pregnancy (treated-BD) and 134 gestationally-unexposed to mood-stabilizers (untreated-BD). BD was significantly-associated with increased risk of gestational-diabetes (adjusted-odds-ratio: 1.75 [95 % CI: 1.15-2.70]) and maternal somatic hospitalization ≤ 90 days post-discharge from index-delivery (2.12 [1.19-3.90]). In treatment status-stratified analyses, treated-BD women exhibited significantly-increased rate of gestational-diabetes (2.09 [1.21-3.70]) relative to controls (non-BD and gestationally-unexposed to mood-stabilizers). No significant association of BD or mood-stabilizers with other adverse outcomes was observed. Overall, our findings indicate that BD and mood-stabilizers are not associated with most adverse pregnancy, delivery and neonatal outcomes. Further research clarifying comparative safety of individual mood-stabilizing agents on pregnancy/neonatal outcomes is required.

BACKGROUND: Self-deferral of men having sex with men (MSM) from blood donation is a means of protecting blood safety. There has recently been a strategy change from permanent to time-limited deferral in some countries. Awareness and attitudes of donors is crucial for effective implementation of MSM deferral or any change of the strategy. STUDY DESIGN AND METHODS: A postdonation survey was administered using a Web-based questionnaire, after explanation by trained volunteers, to evaluate donors' awareness and compliance toward the health history enquiry (HHE, the deferral questionnaire) of the Hong Kong Red Cross Blood Transfusion Service, sexual experiences, and opinions on permanent versus time-limited deferral. RESULTS: A total of 1373 Chinese donors (male:female 1.28:1), a majority (89.1%) of whom were repeat donors, completed the survey at eight blood donation centers. Almost all (98.7%) were aware of HHE, although only half read it in detail, the latter comprising more experienced donors. Most did not hold strong views on deferral, with more than half (59.4%) concurring with both permanent and time-limited deferral. Seventeen (3.2%) of the sexually active male donors were MSM, of whom six disagreed with permanent deferral while seven agreed with changing to time-limited deferral. A simpler question structure was preferred by 57% of the respondents for screening MSM to achieve self-deferral. CONCLUSIONS: Donors generally do not read through the deferral questionnaire in sufficient detail for making an informed decision. Blood safety would eventually depend on donors' compliance with the deferral mechanism, irrespective of whether it is permanent or time-limited.

Introduction: The extent of cognitive impairment and its association with psychological distress among people with pre-existing mental illness during COVID-19 is understudied. This study aimed to investigate prevalence and correlates of subjective cognitive impairment (SCI) in Chinese psychiatric patients during fifth-wave of COVID-19 in Hong Kong (HK). Methods: Four-hundred-eight psychiatric outpatients aged 18-64 years were assessed with questionnaires between 28 March and 8 April 2022, encompassing illness profile, psychopathological symptoms, coping-styles, resilience, and COVID-19 related factors. Participants were categorized into moderate-to-severe and intact/mild cognitive impairment (CI+ vs. CI-) groups based on severity of self-reported cognitive complaints. Univariate and multivariate regression analyses were conducted to determine variables associated with CI+ status. Results: One-hundred-ninety-nine participants (48.8%) experienced CI+. A multivariate model on psychopathological symptoms found that depressive and post-traumatic-stress-disorder (PTSD)-like symptoms were related to CI+, while a multivariate model on coping, resilience and COVID-19 related factors revealed that avoidant coping, low resilience and more stressors were associated with CI+. Final combined model demonstrated the best model performance and showed that more severe depressive and PTSD-like symptoms, and adoption of avoidant coping were significantly associated with CI+. Conclusion: Almost half of the sample of psychiatric patients reported cognitive complaints during fifth-wave of COVID-19 in HK. Greater depressive and PTSD-like symptom severity, and maladaptive (avoidant) coping were found as correlates of SCI. COVID-19 related factors were not independently associated with SCI in psychiatric patients. Early detection with targeted psychological interventions may therefore reduce psychological distress, and hence self-perceived cognitive difficulties in this vulnerable population.
RESUMEN
BACKGROUND: The COVID-19 pandemic significantly increased depression prevalence in general population. However, the relationship between persistent dysfunctional thinking associated with COVID-19 (perseverative-cognition) and depression, and its potential moderators are understudied. We aimed to examine the association between COVID-19 perseverative-cognition and depression, and the moderating effect of potential risk and protective factors on this association in general public during the peak of fifth COVID-19 wave in Hong Kong. METHODS: This survey recruited 14,269 community-dwelling adults between March 15-April 3, 2022 to investigate association between COVID-19 perseverative-cognition and depression, and the moderating effect of resilience, loneliness and three coping strategies (including emotion-focused, problem-focused and avoidant coping) on this association, using hierarchical regression models and simple slope analyses. COVID-19 perseverative cognition was assessed by the Obsession with COVID-19 Scale (OCS) and depressive symptoms were measured by the Patient Health Questionnaire-9 (PHQ-9). RESULTS: Perseverative-cognition was positively associated with depression severity. Resilience, loneliness and three coping strategies moderated the association between perseverative-cognition and depression. Specifically, greater resilience and emotion-focused coping ameliorated the association between perseverative-cognition and depression, while higher levels of loneliness, avoidant and problem-focused coping accentuated such association. LIMITATIONS: Cross-sectional design precluded establishing causality among variables. CONCLUSION: This study affirms that COVID-19 perseverative-cognition is significantly related to depression. Our findings indicate the potential critical role of enhanced personal resilience and social support, and adoption of emotion-focused coping in mitigating negative effect of COVID-19 related maladaptive thinking on depression severity, thereby facilitating development of targeted strategies to reduce psychological distress amidst the prolonged pandemic.

People with mental disorders have increased risk of psychological distress during COVID-19. However, there is limited research comprehensively examining factors associated with suicidal ideation, the strongest predictor of suicidal behavior, among psychiatric patients amidst pandemic. We investigated prevalence and correlates of suicidal ideation in 407 Chinese psychiatric outpatients (diagnosed with mood, anxiety or schizophrenia-spectrum disorders) aged 18-64 years during the peak of fifth COVID-19 wave in Hong Kong between 28 March and 8 April, 2022, based on a comprehensive array of variables encompassing socio-demographics, illness profile, psychopathological symptoms, psychological measures and pandemic-related factors. Univariate and multivariate logistic regression analyses were conducted to determine correlates of suicidal ideation. Results showed that 128 (31.4%) participants exhibited suicidal ideation. Univariate analyses revealed that being unemployed or full-time student, more severe depressive, anxiety, PTSD-like, insomnia and psychotic symptoms, higher levels of loneliness, avoidant-coping, greater pandemic-related stress burden and distress by social-distancing measures were related to suicidal ideation. Conversely, participants with higher monthly household-income, better quality-of-life, and greater resilience were less likely to have suicidal ideation. Notably, only depressive symptom severity was retained in final multivariate model as a factor significantly associated with suicidal ideation. Hence, we observed that approximately one-third of Chinese psychiatric patients experienced suicidal ideation during fifth pandemic wave. Our findings underscore the influence of depressive symptoms being above and beyond that of other psychopathological symptoms, psychological and pandemic-related variables on suicidal ideation. Longitudinal research is required to clarify suicidal ideation trajectories and predictors of persistent suicidal ideation across pandemic and post-pandemic periods.

Introduction: Literature reveals increased suicidal ideation in the general population during pandemic. However, few COVID-19 studies comprehensively assessed factors associated with suicidal ideation, and mixed findings were observed. We aimed to examine prevalence and correlates of suicidal ideation in general public during the peak of fifth COVID-19 wave in Hong Kong based on a broad array of relevant measures. Methods: This survey assessed 14,709 community-dwelling adults during March 15-April 3, 2022. Comprehensive assessment was administered including socio-demographics, pre-existing mental/physical morbidity, mental-health symptoms, resilience, loneliness, coping strategies, and pandemic-related factors. Presence of suicidal ideation was evaluated by ratings of item 9 on Patient-Health-Questionnaire-9. Results: A total of 2,249 (15.3%) participants exhibited suicidal ideation. Multivariable-regression analysis found that being single and unemployed, pre-existing mental disorder, more severe depressive and anxiety symptoms, higher levels of loneliness and engagement in avoidant coping were significantly associated with suicidal ideation. Conversely, attaining tertiary educational level or above, greater resilience and adopting problem-focused coping were associated with lower likelihood of suicidal ideation. Although univariate-analyses revealed that a number of pandemic-related factors were linked to suicidal ideation, none remained significant in the multivariable model. Conclusion: A significant proportion of people experienced suicidal ideation during the peak of fifth COVID-19 wave. Risk and protective factors identified would facilitate early identification of high-risk individuals and provision of targeted interventions to minimize suicidal ideation and risk of self-harm. Caution should be exercised due to study limitations of a cross-sectional design which precluded establishing causality among variables, and reliance on self-reported data.
RESUMEN
INTRODUCTION: Both daily and on-demand regimens have been proven effective for pre-exposure prophylaxis (PrEP) against HIV in men who have sex with men (MSM). We aimed to compare the two regimens on their coverage of condomless anal intercourse (CLAI) in MSM. METHODS: A randomized, controlled, open-label, crossover trial was conducted in a teaching hospital in Hong Kong. Participants were sexually active HIV-negative MSM aged 18 years or above with normal renal function and without chronic hepatitis B infection. Oral tenofovir disoproxil fumarate 300 mg/emtricitabine 200 mg (TDF/FTC) tablets were prescribed for PrEP. After a 2-week lead-in with daily TDF/FTC for treatment-naïve MSM for tolerance assessment, participants were randomly assigned in a 1:1 ratio with a block size of four to either daily-first or on-demand-first arm based on the IPERGAY study, for receiving PrEP for 16 weeks, then crossed-over to the alternative regimen for another 16 weeks. The primary outcome was the proportion of days with PrEP-covered CLAI by intention-to-treat analysis. The trial is registered with the CCRB Clinical Trials Registry, CUHK, CUHK_CCRB00606, and is closed to accrual. RESULTS: Between 25 August 2018 and 23 March 2019, 119 eligible participants were assigned to daily-first arm (n = 59) and on-demand-first arm (n = 60) with an 87% overall completion rate (n = 103). With 96% and 54% of days on PrEP during daily and on-demand periods, respectively, the proportion of days with PrEP-covered CLAI between two arms were not statistically different (92% vs. 92%, p = 0.93). About half (47%) were diagnosed with at least one episode of incident sexually transmitted infection. Mild and time-limited adverse events, including diarrhoea, headache, nausea and dizziness, were reported in 37 (31%) and 10 (8%) during the daily and on-demand periods, respectively. At the end of the study, a similar proportion favoured daily or on-demand regimen. CONCLUSIONS: High prevention-effective adherence, as reflected from the coverage of CLAI, was achievable by either daily or on-demand PrEP among MSM, albeit a higher number of tablets taken for daily PrEP. As both regimens were well accepted, a flexible approach adopting either or both regimens with possible switching is warranted in order to suit individual health needs.

BACKGROUND: Previous studies have shown that men who have sex with men (MSM) and who engage in drug use in sexualized contexts (chemsex) were more likely to be HIV positive. Their social networks and adoption of HIV prevention measures have, however, not been fully investigated. We aim to compare the sexual behavior, HIV prevention efforts and social networks of MSM by the intensity and patterns of their drug use. METHODS: Data from respondents of a community-based, cross-sectional survey (PRiSM) conducted among MSM in Hong Kong in 2017 were collected retrospectively. Characteristics of MSM engaged and not engaged in chemsex were compared in logistic regressions, delineated by latent class analysis (LCA) and compared in multinominal logistic regression. FINDINGS: Of 4133 respondents, 3044 were sexually active with an HIV prevalence of 6.5%. The prevalence of chemsex engagement in the preceding 6 months was 12%, after excluding use of poppers or erectile dysfunction agents (EDA) alone. Four types of drug user were identified by LCA: Minimal (mainly poppers), low-threshold (mainly poppers and EDA), medium-threshold (mainly methamphetamine, GHB, poppers and EDA) and intense (extensive use of different types of drug). Medium-threshold and intense drug users were more likely to be HIV positive, be diagnosed with sexually transmitted infections, make gay friends through mobile apps and sex parties, and intend to take pre-exposure prophylaxis (PrEP). Medium-threshold drug users had a more influential role in their social network, as shown by their higher centrality in mobile apps network. CONCLUSION: Chemsex engagement in MSM is significantly associated with HIV infection in Hong Kong. The HIV transmission risk could however be offset by the inclination of MSM belonging to medium-threshold and intense drug users to take PrEP, should the intervention become accessible to the community. Further mobile apps could be a good channel to access MSM who are medium-threshold drug users.

The Hong Kong HIV Cohort Database is an observational cohort including all patients enrolled in 2 HIV specialist clinical services in Hong Kong. Basic demographics, HIV transmission category, and the diagnoses of AIDS were captured using a standardized template. As of December 2006, 2132 HIV cases had been registered in the database, representing two thirds of all reports submitted to the government's surveillance system. Non-Chinese and young females≤24 years were less represented in the cohort. Description of cohort cases was, however, more complete in terms of transmission category and presentation with AIDS-defining illnesses. Overall, Pneumocystis jirovecci, tuberculosis, and systemic mycosis accounted for a majority of AIDS cases within 3 months of HIV diagnosis. There was a gradual rise of HIV positive men having sex with men in the cohort, notably after 2002, an observation also made in other Asian countries.
