Abstract Aims Suicidal acts may cluster in time and space and lead to community concerns about further imitative suicidal episodes. Although suicide clusters have been researched in previous studies, less is known about the clustering of non-fatal suicidal behaviour (self-harm). Furthermore, most previous studies used crude temporal and spatial information, e.g., numbers aggregated by month and residence area, for cluster detection analysis. This study aimed to (i) identify space–time clusters of self-harm and suicide using daily incidence data and exact address and (ii) investigate the characteristics of cluster-related suicidal acts. Methods Data on emergency department presentations for self-harm and suicide deaths in Taipei City and New Taipei City, Taiwan, were used in this study. In all-age and age-specific analyses, self-harm and suicide clusters were identified using space–time permutation scan statistics. A cut-off of 0.10 for the p value was used to identify possible clusters. Logistic regression was used to investigate the characteristics associated with cluster-related episodes. Results A total of 5,291 self-harm episodes and 1,406 suicides in Taipei City (2004–2006) and 20,531 self-harm episodes and 2,329 suicides in New Taipei City (2012–2016) were included in the analysis. In the two cities, two self-harm clusters (n [number of self-harm episodes or suicide deaths in the cluster] = 4 and 8 in Taipei City), four suicide clusters (n = 3 in Taipei City and n = 4, 11 and 4 in New Taipei City) and two self-harm and suicide combined clusters (n = 4 in Taipei City and n = 8 in New Taipei City) were identified. Space–time clusters of self-harm, suicide, and self-harm and suicide combined accounted for 0.05%, 0.59%, and 0.08% of the respective groups of suicidal acts. Cluster-related episodes of self-harm and suicide were more likely to be male (adjusted odds ratio [aOR] = 2.22, 95% confidence interval [CI] 1.26, 3.89) and young people aged 10–29 years (aOR = 2.72, 95% CI 1.43, 5.21) than their cluster-unrelated counterparts. Conclusions Space–time clusters of self-harm, suicide, and self-harm and suicide combined accounted for a relatively small proportion of suicidal acts and were associated with some sex/age characteristics. Focusing on suicide deaths alone may underestimate the size of some clusters and/or lead to some clusters being overlooked. Future research could consider combining self-harm and suicide data and use social connection information to investigate possible clusters of suicidal acts.

Background Childhood adversities (CAs) have been found to be associated with problem behaviors in adolescents; however, the mediators—that help build resilience and prevent some children who experience CAs from engaging in problem behaviors—await more exploration, including social integration. The aim of this study is to identify the association between CAs and adolescent problem behaviors, and to further examine the mediating role of social integration distinctly as psychological and structural integration. Methods Data used were from the Taiwan Education Panel Survey, a core panel of 4,261 students (age 13) surveyed in 2001 and followed for three more waves until age 18. For psychological integration, an average score was calculated to represent adolescents’ feelings about their school. Structural integration was constructed by several items about adolescents’ school and extracurricular activities. We used structural equation modeling with diagonally weighted least squares method to examine the effect of CA on the primary outcome—adolescent problem behaviors via social integration. Results The hypothesized structural equation model specifying the path from childhood adversity to adolescent problem behavior showed good fit. Respondents with one CA were indirectly linked to problem behaviors via psychological but not structural integration—the level of participation in school and non-school activities. Results of mediation analysis showed that psychological integration significantly mediated the paths from one CA to all six problem behaviors (all ps

BACKGROUND A comparison of the performance between monetary and an asset-based socioeconomic position (SEP) index in predicting adolescents' health outcomes was conducted only in low-income countries. Our study aims to compare these two indices among adolescents from low-income families in a high-income country. METHODS Data of adolescents aged 12-18 years was used from the Taiwan Database of Children and Youth in Poverty (n = 2529). The asset-based index was based on a set of weighted self-reported household conditions using principal components analysis. Multivariable logistic regression was conducted to examine the association between these two indices and the mental and physical health outcomes among adolescents. RESULTS Health outcomes were significantly associated with the asset-based SEP index but not with the monetary index. An increased trend was shown in mental illness symptoms, infections, injuries, allergies and dental problems when the regression was performed in the asset-based SEP index (P < 0.05) but not in the monetary SEP index. CONCLUSIONS An asset-based SEP index serves as a better index associated with a social gradient in health inequality. To prioritize giving care to people in need, healthcare policymakers should consider including an assessment of household assets and resources, supplementary to the conventional monetary index.

ObjectivesMen who have sex with men (MSM) are a highly neglected population in the current recommendation of girls-only human papillomavirus (HPV) vaccination programmes in many countries. To better assess the cost effectiveness of HPV vaccination among men requires data on the prevalence of HPV infection in MSM using a community sample, which is still sparse in several regions. We examined the prevalence of and factors associated with anogenital HPV infection among MSM in Taiwan.MethodsMSM 20 years of age and older were recruited from the community and social media in Taiwan in 2015–2016 and screened for HPV infection to detect 37 genotypes. MSM were seen at baseline and were/will be seen at 6, 12, 24 and 36 months. Men completed a questionnaire regarding their sexual experiences. Multivariable regression analyses were conducted to identify associated behavioural risk factors using the baseline data.ResultsA total of 253 MSM were recruited; 87 % were below 35 years of age. Diagnosis of HIV was reported in 4% of men; just over 20% had three or more anal sex partners in the past year. The prevalence of any tested HPV type was 29.4% at the anal site and 11% at the penile site. One quarter of MSM were infected with any of the 9-valent vaccine HPV types. Anal HPV detection was associated with having three or more receptive anal sex partners in the past year (adjusted odds ratio (aOR)=2.92, 95% CI 1.29 to 6.61) and having older sex partners (aOR=2.51, 95% CI 1.07 to 5.90).ConclusionsOur data provide the base to calculate the reproductive rate for HPV transmission in a low-risk community sample and cost-effectiveness to include men in HPV vaccination policies. Adding evidence from a community sample adds comprehensiveness for future estimates of disease transmission and vaccine effectiveness.
