Abstract Background The human immunodeficiency virus (HIV) epidemic has been drastically increasing among men who have sex with men (MSM) in China over the past decade. More so, the number of HIV infections among young adults in the country has also been on the rise, highlighting a unique sub-population, which may lead to increased incidence and transmission of the disease. This study aimed to determine the HIV infection rate amongst student and non-student young men who have sex with men (YMSM) in three regions in China and factors associated with their HIV infection. Methods A cross-sectional study was conducted from 1 September to 6 September 2017 in Beijing, Sichuan, and Guangzhou). Participants were recruited through a popular Chinese gay social networking application, as well as several college-based youth associations. Univariate and multivariate logistic regression analyses were conducted to assess factors associated with HIV infection. Results The HIV infection rate among non-student YMSM was significantly higher than that of student YMSM (10.3% versus 5.3%, χ2trend=17.34, P<0.001). The multivariate logistic regression analysis showed that YMSM self-identifying as homosexual (AOR=2.81, 95%CI=1.40-5.66, P=0.004) and perceived themselves at risk for HIV (AOR=3.08, 95:CI:1.33-7.15, P=0.009) had a 3 times increased odds of being HIV positive. Additionally, participants whom reported not always using condoms with sex partners in the past six months (AOR=1.69, 95%CI=1.17-2.44, P=0.006) were at increased odds of HIV infection. Conclusions Young men who have sex with men, particularly those identifying as homosexual and not always using condoms during intercourse, are at increased odds of HIV infection in China. Promoting comprehensive sexual education to youth and other measures aimed at improving HIV knowledge could help control HIV transmission among this key sub-population.

Objective: We aimed to determine the prevalence of social isolation and associated factors among adults with epilepsy in northeast China.Methods: A cohort of consecutive patients with epilepsy (PWE) from the First Hospital of Jilin University (Changchun, China) was recruited. Demographic and clinical data for each patient were collected during a face-to-face interview. Social isolation was measured using the Berkman-Syme Social Network Index (SNI), and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) and Quality of Life in Epilepsy Inventory (QOLIE-31) were also administered. Multivariate logistic regression analyses were used to determine the factors associated with social isolation in PWE.Results: A total of 165 patients were included in the final analysis. The mean SNI score was 2.56 (SD: 1.19), and 35 patients (21.2%) were socially isolated. In multivariate logistic regression analysis, higher depressive symptom levels (OR = 1.15, 95% CI: 1.003–1.318, P = 0.045) and poorer quality of life (OR = 0.967, 95% CI: 0.935–0.999, P = 0.047) emerged as independent factors associated with social isolation in PWE.Conclusion: Social isolation is common and occurs in approximately one-fifth of PWE. Social isolation is significantly associated with depressive symptoms and poor quality of life in PWE. Patients need to be encouraged to actively integrate with others and reduce social isolation, which may help improve their quality of life.

UNSTRUCTURED COVID-19 has been particularly devastating to Black and Latinx communities in the U.S. However, data on acceptability of the COVID-19 vaccines among minority populations are limited. We conducted an online survey among adults in Puerto Rico to identify factors associated with intention to vaccinate against COVID-19. Sociodemographic variables were analyzed independently for association with intention to vaccinate. Significant associations were included in the multivariate logistic regression analysis. A total of 1016 responses were available for analysis. In the bivariate analysis, younger age, higher education, pre-covid employment, male sex, gay/bisexual identity, and single marital status were associated with increased intention to vaccinate. In the multivariate logistic regression, younger, male respondents who had higher educational attainment reported higher intention to vaccinate. Lower-income and living outside the San Juan metro region were associated with lower intention to vaccinate. National and international health organizations were identified as the most reliable sources of information, followed by healthcare professionals. These findings highlight the importance of considering sociodemographic characteristics identified with low intention to vaccinate as well as using trusted sources of information when designing public messaging related to increasing COVID-19 vaccinations.

Background/Aim. The assessment of association of depression and diabetes mellitus type 2 using the Patient Health Questionaire (PHQ-9) has not been done in Montenegro. The aim of this study was to assess the prevalence of depression in the patients with type 2 diabetes mellitus, and to identify the risk factors associated with the presence of depression. Methods. A cross-sectional study was conducted at the General Hospital in Bijelo Polje, from July to September, 2015. It included 70 patients over 35 years of age with the diagnosis of diabetes for at least six months. For the assessment of depression presence and intensity PHQ?9 was used. All variables associated with the presence of depression at a significance level of p < 0.05 were included into the final method of the multivariate logistic regression analysis. Results. Comorbidities were statistically significant more frequent among patients with depression (?2 = 5.40; p = 0.020). Duration of diabetes over five years was significantly associated with depression (?2 = 12.48; p < 0.001). Depression occurred more frequently among physically inactive subjects (?2 = 10.74; p = 0.005). The presence of diabetic polyneuropathy (?2 = 6.04; p = 0.014) and cataract (?2 = 5.351; p = 0.021) were also significantly associated with depression. A multivariate logistic regression analysis showed that the duration of diabetes over five years and presence of cataract were independently associated with depression. Conclusion. The risk factors for depression among the subjects with diabetes were disease duration more than five years and the presence of cataract. Since depression is a serious disease and can be a risk factor for many chronic diseases, the best way of prevention is its early detection and treatment.

ABSTRACT Objective: The purpose of this study was to investigate the diagnostic aspects, contributing conditions, and predictive key factors associated with ectopic eruption of maxillary second molars. Material and Methods: This retrospective study evaluated the study models, lateral cephalographs, and panoramic radiographs of 40 adult subjects (20 men, 20 women) with bilateral ectopic eruption and 40 subjects (20 men, 20 women) with normal eruption of the maxillary second molars. Studied variables were analyzed statistically by independent t-tests, univariate and multivariate logistic regression analysis, followed by receiver-operating characteristic analysis. Results: Tooth widths of bilateral lateral incisors, canines, and premolars were wider in the ectopic group, which resulted in greater arch lengths. The ANB angle and maxillary tuberosity distance (PTV-M1, PTV-M2) were smaller in the ectopic group. The long axes of the maxillary molars showed significant distal inclination in the ectopic group. The multivariate logistic regression analysis showed that three key factors—arch length, ANB angle, and PTV-M1 distance—were significantly associated with ectopic eruption of the second molars. The area under the curve (AUC) was the largest for the combination of the three key factors with an AUC greater than 0.75. PTV-M1 alone was the single factor that showed the strongest association with ectopic eruption (AUC = 0.7363). Conclusions: An increase in arch length, decrease in ANB angle, and decrease in maxillary tuberosity distance to the distal aspect of the maxillary first molar (PTV-M1) were the most predictive factors associated with ectopic eruption of maxillary second molars.

Objective. To analyze sociodemographic and behavioral factors associated with vulnerability to HIV according to sexual orientation. Method. This is a cross-sectional study conducted using data on 3,818 people in the city of Imperatriz, Brazil, during 2015 and 2016. The survey’s questionnaires addressed sociodemographic and behavioral variables. For the data analysis, association (chi-square test) and strength of association (odds ratio) were observed. A significance level of p<0.05 and adjustment for age and gender were taken into consideration. Results. A substantial portion of the sample stated they were heterosexual (88.8%). These individuals demonstrated a lower chance of HIV infection (p<0.001), sexually transmitted infections (p<0.001), alcohol use (p<0.001) and condom use (p<0.001), compared to men who have sex with men and/or bisexuals. In this group, after adjusting for confounding variables, the factors associated with HIV infection were being male (p<0.001), unmarried (p<0.001), having completed higher education (p<0.001) and boasting multiple sexual partners (p<0.001). Conclusion. Behavioral and sociodemographic factors of vulnerability to HIV are predominant among men who have sex with men and/or are bisexual.

ObjectivesThis study aims to determine the prevalence of and factors associated with underweight children under the age of 5 in Punjab, Pakistan.DesignWe analysed cross-sectional household-level subnationally representative Multiple Indicator Cluster Survey.SettingsPunjab province, Pakistan.Participants24 042 children under 5 years of age.Data analysisMultilevel multivariate logistic regression analysis.ResultsPrevalence of moderately and severely underweight children was found to be (33.3% and 11.3%, respectively). Multivariate multilevel logistic regression results show that as the child grows older the likelihood of the child being underweight increases significantly (eg, children between 12 and 23 months are one and half times more likely to be underweight, whereas children between the ages of 36 and 47 months are two and a half times more likely to be underweight). Gender was found to be another significant factor contributing to underweight prevalence among children under the age of 5. The likelihood of a girl child being underweight is more than that of a boy child being underweight (OR 0.92, 95% CI 0.8 to 1.0). Similarly, a child whose birth order is three or more is two times more likely to be underweight (OR 1.96, 95% CI 1.5 to 2.5) relative to a child of a lower birth order. Moreover, diarrhoea also significantly increases the likelihood of the child being underweight (OR 1.31, 95% CI 1.1 to 1.5). Child size is another determinant for underweight prevalence among children under 5, for example, a child with a size smaller than average at the time of birth is 2.7 times more likely to be moderately underweight than a child with an average or larger than average size at the time of birth.ConclusionRigorous community-based interventions should be developed and executed throughout the province to improve this grave situation of underweight prevalence in Punjab. Mother’s education should be uplifted by providing them formal education and providing awareness about the importance of proper nutrition for children.

ObjectiveTo examine the trends of HIV prevalence, risk behaviours and HIV testing among men who have sex with men (MSM) in Nanjing.DesignFive consecutive cross-sectional surveys.SettingNanjing, China.Primary and secondary outcome measuresHIV and syphilis prevalence, HIV testing rate and factors associated with HIV infection; demographic characteristics and behaviours.Results649, 669, 577, 633, 503 MSM were recruited from 2013 to 2017. HIV prevalence was 9.9%, 12.3%, 12.5%, 9.8% and 10.1%, respectively. Syphilis prevalence decreased with a range from 10.6% to 5.6%. Risk behaviours like unprotected anal intercourse (UAI) and unprotected virginal sex in the past 6 months decreased, but multiple sex partners and ever used rush popper rose significantly. MSM tested for HIV in the previous year remained stable from 57.0% to 64.1% (P=0.633). Multivariate analysis showed that tested for HIV in the past year was protective factor against HIV infection. MSM who had UAI in the past 6 months, sex role as receptive and dual, diagnosed with sexually transmitted diseases (STDs) in the past year and currently syphilis infected were risk factors for HIV infection.ConclusionsWe observed stable high HIV prevalence, a steady HIV testing rate, decreasing syphilis prevalence and UAI among MSM in Nanjing. However, rush popper use rose dramatically. The HIV preventive strategies for MSM including condom promotion, HIV testing expansion and reduction of rush popper use, STDs screening and standardised treatment should be strengthened.

Objective. This is the first study in China to examine the use of nitrite inhalants and its correlates among men who have sex with men (MSM) in Beijing, China.Methods. A cross-sectional survey was conducted in 2012. Structured interviews collected data on demographics, sexual and drug use behaviors, and the use of HIV services. Blood specimens were collected and tested for HIV and syphilis.Results. A total of 400 MSM eligible for the study were between 19 and 63 years of age and overall HIV prevalence was 6.0% (9.0% among nitrite inhalant users and 3.3% among nonusers). Nearly half (47.3%) of them reported ever using nitrite inhalants and 42.3% admitted using nitrite inhalants in the past year. Multivariable logistic analysis revealed that ever using nitrite inhalants in the past was independently associated with being aged≤25years, having higher education attainment, seeking sex via Internet, having casual partners in the past three months, and being HIV positive.Conclusion. The use of nitrite inhalants was alarmingly prevalent among MSM in Beijing. The independent association of the nitrite inhalant use with more casual sex partners and HIV infection underscored the need for intervention and prevention of nitrite inhalant use.

The Relationship

Background: Although various modalities of hemodialysis (HD) are presumed to have different effects on insulin resistance (IR), the relationship between hemodiafiltration (HDF) and IR has not been fully evaluated. Methods: In a cross-sectional study, 82 non-diabetic HD patients were enrolled. The patients were divided into two groups according to the median homeostasis model assessment index (HOMA-IR) value of 1.685. Clinical and biochemical data were compared, and multivariate logistic regression analysis was performed to identify the independent factors associated with higher HOMA-IR. Results: The higher HOMA-IR group had increased body mass index (BMI), decreased HDL cholesterol, and lower beta-2 microglobulin reduction rate (β2-MG RR) compared to the lower HOMA-IR group. HOMA-IR was significantly correlated with β2-MG RR. In addition, HDF patients had lower HOMA-IR levels compared with low flux hemodialysis patients. On multivariate logistic regression analysis, BMI and HDF treatment were independent factors associated with higher and lower HOMA-IR, respectively. Conclusion: This study suggests that HDF treatment may reduce IR in non-diabetic HD patients.

In Jamaica, where homosexuality is criminalized, scant research has examined associations between sexual stigma and HIV infection. The study objective was to examine correlates of HIV infection among men who have sex with men (MSM) in Jamaica. We conducted a cross-sectional tablet-based survey with MSM in Jamaica using chain referral sampling. We assessed socio-demographic, individual, social, and structural factors associated with HIV infection. A logit-link model, fit using backwards-stepwise regression, was used to estimate a final multivariable model. Among 498 participants (median age: 24, interquartile range: 22–28), 67 (13.5%) were HIV-positive. In the multivariable model, HIV infection was associated with increased odds of socio-demographic (older age, odds ratio [OR]: 1.05, 95% confidence interval [CI]: 1.00–1.10]; residing in Kingston versus Ocho Rios [OR: 6.99, 95% CI 2.54–19.26]), individual (poor/fair versus excellent/good self-rated health [OR: 4.55, 95% CI: 1.81–11.42], sexually transmitted infection [STI] history [OR: 3.67, 95% CI: 1.61–8.38]), and structural (enacted sexual stigma [OR: 1.08, 95% CI: 1.01–1.15], having a health care provider [OR: 2.23, 95% CI: 1.06–4.66]) factors. This is among the first studies to demonstrate associations between sexual stigma and HIV infection in Jamaica. Findings underscore the need to integrate STI testing in the HIV care continuum and to address stigma and regional differences among MSM in Jamaica.
