Prevalence and risk factors of the co-occurrence of physical frailty and cognitive impairment in Chinese community-dwelling older adults

This cross-sectional study aimed to determine the prevalence of the co-occurrence of physical frailty and cognitive impairment and to identify its associated demographic, psychosocial and behavioural factors. Participants were recruited from 32 neighbourhoods using multistage sampling method in Xuhui District, Shanghai, China. A total of 1585 older adults were included who lived in community, were 75 years or older and without a clinical diagnosis of dementia. Based on the presences of frailty (using the modified frailty phenotype criteria) and/or cognitive impairment (using Chinese version Mini-Mental Status Examination stratified by educational level), the participants were classified into four groups: normal, cognitive impairment alone, frailty alone and co-occurrence. Multinomial logistic regression analyses were conducted to identify the demographic, psychosocial (depression, social participation and social support) and behavioural (sedentary lifestyle and sleep problems) characteristics associated with the co-occurrence of physical frailty and cognitive impairment. The prevalence of frailty alone, cognitive impairment alone and the co-occurrence of physical frailty and cognitive impairment in the study sample were 7%, 26.94% and 7.19% respectively. The results of multinomial logistic regression show the following characteristics significantly associated with the co-occurrence of physical frailty and cognitive impairment: advanced age (81–85 years old, Odds Ratio, OR = 1.99, 95% CI = 1.10–3.59; 86 years or older, OR = 6.43, 95% CI = 3.66–11.29), number of co-morbidities (OR = 1.34, 95% CI = 1.01–1.77), depression (OR = 3.88, 95% CI = 2.39–6.29), social participation (OR = 0.61, 95% CI = 0.39–0.96), sedentary lifestyle (OR = 2.69, 95% CI = 1.66–4.34) and sleep problems (insomnia occasionally, OR = 1.84, 95% CI = 1.07–3.17; insomnia every day, OR = 2.38, 95% CI = 1.33–4.26). The co-occurrence of physical frailty and cognitive impairment is a prevalent health issue in oldest old community-dwelling older adults. Advanced age, co-morbidity, depression, sedentary lifestyle and sleep problems are risk factors for cognitive frailty while good social participation may have a protective effect on it.     

Association of Child Marriage With Suicidal Thoughts and Attempts Among Adolescent Girls in Ethiopia

PurposeLittle information exists on the mental health implications of child marriage in Africa. This study examined the association between child marriage and suicidal ideation and suicide attempt among girls aged 10–17 years.MethodsData were drawn from a 2007 cross-sectional survey conducted in the Amhara region, Ethiopia. Multilevel logistic regression was used to analyze risk factors for suicidality.ResultsApproximately 5.2% of girls reported ever being married, 5.4% were promised in marriage, and 9.3% reported receiving marriage requests. Girls who were ever married (odds ratio [OR] = 1.81; 95% confidence interval [CI] = 1.03–3.18), were promised in marriage (OR = 2.35; 95% CI = 1.38–4.01) or had received marriage requests (OR = 2.29; 95% CI = 1.46–3.59) were significantly more likely than girls who were never in the marriage process to have had suicidal thoughts in the past 3 months. Residence in communities with high involvement in stopping child marriage was protective of suicidal ideation. The odds of suicide attempt were twice as high among girls with marriage requests as among those with none.ConclusionsChild marriage was associated with increased odds of suicidality. Findings call for stronger community engagement in child marriage prevention and mental health support for child brides.     

Coincident alcohol dependence and depression increases risk of suicidal ideation among Army National Guard soldiers

PurposeSuicide rates among military service members have risen dramatically, while drivers remain poorly understood. We examined the relationship between coincident alcohol dependence and depression in shaping risk of suicidal ideation among National Guard forces.MethodsWe performed a longitudinal analysis using a randomly selected, population-based sample of Ohio Army National Guard soldiers. Telephone-based surveys of 1582 soldiers who participated in both wave 1 (2008–2009) and wave 2 (2009–2010) were analyzed.ResultsOdds ratios (ORs) for suicidal ideation among those with versus without alcohol dependence were similar among nondepressed (OR = 3.85 [95% confidence intervals (CIs) = 1.18–12.52]) and depressed individuals (OR = 3.13 [95% CI = 0.88–11.14]); multiplicative interaction was not observed. In contrast, the risk differences (RDs) among those with versus without alcohol dependence diverged for those without depression (RD = 0.04 [95% CI = 0.02–0.07]) compared with those with depression (RD = 0.11 [95% CI = 0.06–0.18]); strong evidence of additive interaction was observed.ConclusionsWe found that alcohol dependence and depression interact statistically in shaping risk for incident suicidal ideation among Army National Guard service members. A high-risk prevention approach including population-based screening for suicidality among patients with alcohol dependence, depression, and particularly those with both conditions is warranted in military populations.     

Immigrant Density, Sense of Community Belonging, and Suicidal Ideation Among Racial Minority and White Immigrants in Canada

Immigrants represent a substantial proportion of suicides in Canada. This study assesses the hypothesis that high immigrant density fosters personal sense of community belonging among immigrants, and in turn, protects against suicide risk. This multilevel cross-sectional study is based on individual-level data from the 2007 Canadian Community Health Survey (n = 12,951 participants) merged with area-level data from the 2006 Canadian census (n = 57 health regions). Prevalence of suicidal ideation was 1.3 %. Among rural racial minority immigrants, each 10 % increase in immigrant density associated with 67 % lower odds of suicidal ideation (adjusted odds ratio (AOR) = 0.33, 95 % CI: 0.14–0.77); sense of community belonging did not mediate this association, but was independently associated with suicidal ideation (AOR = 0.44, 95 % CI: 0.28–0.69). Immigrant density was not associated with suicidal ideation among white immigrants or urban settings. Immigrant density and sense of community belonging may correlate with suicidal ideation through distinct mechanisms of association.     

Prospective COVID-19 related changes in physical activity and sedentary time and associations with symptoms of depression and anxiety

ProblemThe COVID-19 pandemic is associated with psychological distress. Decreased moderate-vigorous physical activity (MVPA) and increased sedentary time may be exacerbating pandemic-related symptoms of anxiety and depression, but existing studies exploring these associations are almost entirely cross-sectional.MethodsReported data from 2018 and Summer 2020 were used to create change categories based on compliance with MVPA guidelines and relative sedentary time. Participants completed the Patient Health Questionnaire-4 (PHQ-4) in Summer 2020. Associations among changes in MVPA and sedentary time (separately and jointly) with psychological distress (total PHQ-4 score) were examined with ordinal logistic regression and associations with depressive or anxiety symptoms were examined with logistic regression.ResultsAmong 2,240 participants (65% women, mean age 57.5 years), 67% increased sedentary time and 21% became inactive between the two time points. After multivariate adjustment, participants who became (OR = 1.71, 95% CI: 1.05–2.78) or remained inactive (OR = 2.07, 1.34–3.22) were more likely to experience depressive symptoms compared to those who remained active. Participants who increased sedentary time were also more likely to experience depressive symptoms compared to those who maintained sedentary time (OR = 1.78, 1.13–2.81). Jointly, those who increased sedentary time while remaining (OR = 3.67, 1.83–7.38) or becoming inactive (OR = 3.02, 1.44–6.34) were much more likely to have depressive symptoms compared to the joint referent (remained active/maintained sedentary time). Associations with anxiety symptoms were not statistically significant.ConclusionsThese findings support the value of promoting MVPA and limiting sedentary time during stressful events associated with psychological distress, like the COVID-19 pandemic.     

Association between Sexual Behaviors,Bullying Victimization and Suicidal Ideation in a National Sample of High School Students: Implications of a Sexual Double Standard

PurposeThe sexual double standard is the notion that women are more harshly judged for their sexual behaviors than men. The purpose of this study was to investigate if the sexual double standard could explain gender differences in bullying victimization among adolescents and the extent to which that relationship correlated with depression and suicidal ideation.MethodsAnalyses were conducted using a sample of high school students (n = 13,065) from the 2011 Youth Risk Behavior Survey, a cross-sectional and national school-based survey conducted by the Centers for Disease Control and Prevention. Data were assessed using multiple logistic regression, gender-stratified analyses, and interaction terms.FindingsStudents who engaged in sexual intercourse (sexually active) had higher odds of being bullied. When this association was stratified by gender, odds of being bullying increased for girls (odds ratio [OR], 1.83; 95% CI, 1.58–2.13) and decreased for boys (OR, 0.94; 95% CI, 0.77–1.16). Sexually active students who were bullied also displayed more than five times (OR, 5.65; 95% CI, 4.71–6.78) the adjusted odds of depression and three times (adjusted OR, 3.38; 95% CI, 2.65–4.32) the adjusted odds of suicidal ideation compared with students who reported neither of those behavioral characteristics. When stratified by gender, girls had slightly higher odds of depression and suicidal ideation but overall, the odds remained strong for both genders.ConclusionsResults provide some evidence that a sexual double standard exists and may play a prominent role in bullying victimization among girls. Therefore, addressing the sexual double may be important to consider when tailoring school bullying intervention programs.     

Predictors of herpes zoster vaccination among Australian adults aged 65 and over

Objective(s)To estimate HZ vaccine coverage in Australia among older Australians and to identify potential barriers to vaccination.DesignAnalysis of data from three cross-sectional surveys administered online between 2019 and 2020.Setting and participantsAdults aged 65 and over residing in Australia.Main outcome measuresSelf-reported herpes zoster vaccination.ResultsAmong the 744 adults aged 65 and over in this sample, 32% reported being vaccinated for HZ, including 23% of participants aged 65–74, 55% of participants aged 75–84, and 0% for participants aged 85 and above. Those who are vaccinated with other immunisations are more likely to have received HZ vaccine, including seasonal influenza (OR = 4.41, 95 % CI: 2.44–7.98) and pneumococcal vaccines (OR = 4.43, 95 % CI: 2.92 – 6.75). Participants with a history of certain conditions, such as stroke (OR = 2.26, 95 % CI: 1.13–4.49), were more likely to be vaccinated against HZ. Participants that reported smoking tobacco daily were less likely to be vaccinated against HZ (OR = 0.48, 95 % CI: 0.26–0.89). Participants were less likely to be vaccinated against HZ if they preferred to develop immunity ‘naturally’ (OR = 0.29, 95 % CI: 0.15 – 0.57) or expressed distrust of vaccines (OR = 0.34, 95 % CI: 0.13–0.91).Conclusion(s)Further research is required to understand the barriers to HZ vaccine uptake. Increasing the funding eligibility for those who are at risk of complications from shingles, or lowering the age of eligibility, may increase vaccine coverage.     

Knowledge,attitude, and perception regarding HPV-related diseases and vaccination among the general public in Guizhou Province of China

BackgroundThe rising prevalence of high-risk human papillomavirus (HR-HPV) type-related diseases pose an ongoing health challenge in China. In this study, we assessed the current views of the general public of the Guizhou Province on HPV and HPV vaccinations to provide recommendations for future directions regarding the rollout of HPV vaccination in the area.MethodsAn online questionnaire survey was conducted that included 3412 (2532 females and 880 males) native adult residents of the Guizhou Province. Data on the socio-demographic characteristics, knowledge of HPV, and perceptions of HPV vaccinations were collected. Data comparisons were made between students and non-students and between participants with and without medical backgrounds. All statistical analyses were performed using SPSS 26.0.ResultsThe self-reported HPV infection rates were 5.85% in women and 0.86% in men. A total of 46.29% of women and 34.43% of men achieved acceptable knowledge levels of HPV and 47.54% of women possessed an acceptable knowledge level of HPV vaccines. Non-students and medical participants performed significantly better in the knowledge tests than their respective opposing groups. Online media was the most popular HPV information source for all the participants. A total of 93.58% of women and 87.88% of men expressed willingness toward HPV vaccination. The major facilitators of vaccination acceptance were females (OR = 1.932, 95% CI: 1.390–2.685, p < 0.001) or students (OR = 2.276, 95% CI: 1.207–4.291, p = 0.011), and participants with higher HPV knowledge level (OR = 1.796, 95% CI: 1.300–2.481, p < 0.001). Ages 41–50 (OR = 0.255, 95% CI: 0.121–0.538, p = 0.001) or > 50 (OR = 0.141, 95% CI: 0.059–0.337, p < 0.001) were significant predictors of a negative attitude towards HPV vaccination.ConclusionGuizhou residents had poor knowledge of HPV-related issues. The percentage of healthcare workers who achieved acceptable knowledge levels was one-half or less. The increasing HPV prevalence and cervical cancer incidence can be contained if more affordable vaccines are developed and the low knowledge levels pervading young adults and medical staff is eliminated.     

COVID-19 vaccine hesitancy among persons living in homeless shelters in France

COVID-19 vaccine hesitancy is frequent and can constitute a barrier to the dissemination of vaccines once they are available. Unequal access to vaccines may also contribute to socioeconomic inequalities with regard to COVID-19. We studied vaccine hesitancy among persons living in homeless shelters in France between May and June 2020 (n = 235). Overall, 40.9% of study participants reported vaccine hesitancy, which is comparable to general population trends in France. In multivariate regression models, factors associated with vaccine hesitancy are: being a woman (OR = 2.55; 95% CI 1.40–4.74), living with a partner (OR = 2.48, 95% CI 1.17–5.41), no legal residence in France (OR = 0.51, 95% CI 0.27–0.92), and health literacy (OR = 0.38, 95% CI 0.21, 0.68). Our results suggest that trends in vaccine hesitancy and associated factors are similar among homeless persons as in the general population. Dissemination of information on vaccine risks and benefits needs to be adapted to persons who experience severe disadvantage.     

Positive attitudes towards persons living with HIV in North Kosovo: The university students' perspective

HIV-related stigma could delay the identification and treatment of persons living with HIV (PLHIV), particularly in regions affected by ethnic conflicts. The aims of this study were to assess attitudes towards PLHIV and examine factors associated with stronger positive attitudes towards PLHIV among university students in the Serbian province of Kosovo. A cross-sectional study was conducted at the University of Pristina temporarily settled in Kosovska Mitrovica during the academic year 2013–2014. A total of 1,017 first- and fourth-year students completed an anonymous questionnaire about socio-demographic characteristics, PLHIV, high-risk groups for acquiring HIV and health behaviour. The main outcome measure was the Attitude Score (ATS), calculated as a sum of points awarded for all attitude-related items. The majority of students (84%) expressed positive attitudes towards PLHIV, while others were indecisive. Most students held negative opinions about persons who use drugs (64%), homosexual persons of both genders (50%) and sex workers (42%). Being female (odds ratio [OR] = 1.49, 95% confidence interval [CI] 1.05–2.09) and older (OR = 1.13, 95% CI 1.03–1.24), not doing paid work while studying (OR = 3.35, 95% CI = 1.63–6.84), studying health-related disciplines (β = −0.113, 95% CI = −0.085 to −2.747), having stronger positive attitudes towards homosexual persons of both genders (OR = 0.77, 95% CI = 0.64–0.94) and not using illicit drugs (β = 2.08, 95% CI = 1.03–4.20) were associated with stronger positive attitudes towards PLHIV. Social inclusion of PLHIV and individuals at high risk for acquiring HIV could help reduce the HIV-related stigma.     

Dutch homeless people 2.5 years after shelter admission: what are predictors of housing stability and housing satisfaction?

Housing stability is an important focus in research on homeless people. Although definitions of stable housing differ across studies, the perspective of homeless people themselves is generally not included. Therefore, this study explored the inclusion of satisfaction with the participant's current housing status as part of the definition of housing stability and also examined predictors of housing stability with and without the inclusion of homeless person's perspective. Of the initial cohort consisting of 513 homeless participants who were included at baseline in 2011, 324 (63.2%) were also interviewed at 2.5‐year follow‐up. To determine independent predictors of housing stability, we fitted multivariate logistic regression models using stepwise backward regression. At 2.5‐year follow‐up, 222 participants (68.5%) were stably housed and 163 participants (51.1%) were stably housed and satisfied with their housing status. Having been arrested (OR = 0.36, 95% CI: 0.20–0.63), a high level of somatisation (physical manifestations of psychological distress) (OR = 0.52, 95% CI: 0.30–0.91) and having unmet care needs (OR = 0.77, 95% CI: 0.60–0.99) were negative predictors of housing stability. Having been arrested (OR = 0.43, 95% CI: 0.25–0.75), high debts (OR = 0.45, 95% CI: 0.24–0.84) and a high level of somatisation (OR = 0.49, 95% CI: 0.28–0.84) were negative predictors of stable housing when satisfaction with the housing status was included. Because inclusion of a subjective component revealed a subgroup of stably housed but not satisfied participants and changed the significant predictors, this seems a relevant addition to the customary definition of housing stability. Participants with characteristics negatively associated with housing stability should receive more extensive and individually tailored support services to facilitate achievement of housing stability.     

Low Risk Sexual and Drug-Using Behaviors Among Latina Women with AIDS in Los Angeles County

Latina women represent nearly half of all females diagnosed with AIDS in Los Angeles County, yet little is known about their risk behaviors compared to women of other race/ethnicities. Compared to white and African American women with AIDS, Latinas with AIDS had fewer lifetime male sexual partners (P < .0001); reported fewer sexually transmitted diseases (OR = 0.24; 95% CI: 0.1, 0.5); were less likely to trade sex for drugs/money (OR = 0.18; 95% CI: 0.07, 0.5); and were less likely to report exposure to HIV via injection drug use (OR = 0.3; 95% CI: 0.09, 0.99). Latinas were also more likely to be single mothers (OR = 3.02; 95% CI: 1.4, 6.4); less likely to receive public assistance (OR = 0.33; 95% CI: 0.16, 0.70); were less likely to have completed high-school (OR = 0.11; 95% CI: .04, .31) and were more likely to never have had health insurance (OR = 2.44; 95% CI: 1.15, 5.18). The data demonstrate low-risk behaviors for Latinas and underscores the challenge of delivering effective HIV prevention to women without traditional risk profiles.     

The Association of Soft Drink Consumption and the 24-Hour Movement Guidelines with Suicidality among Adolescents of the United States

Background: Evidence is lacking for the association of the behaviors of the 24 h movement guidelines including sleep duration, physical activity, screen time, and soft drink consumption with suicidality among adolescents. Methods: Data were extracted from a national representative sample of Youth Risk Behavior Surveys (YRBS) in the United States from 2011 to 2019. Binary logistic regression models with complex sampling designs were used to explore the association of the recommendations of the 24 h movement guidelines and soft drink consumption with suicidality. Results: The total prevalence of suicidal ideation, suicide plan, suicide attempt, and suicide attempt with medical treatment was higher among adolescents who did not meet all the recommendations in the 24 h movement guidelines and had a higher level of soft drink consumption. Totally, not meeting all the recommendations of the 24 h movement guidelines was significantly associated with an increased risk of suicidal ideation (OR: 1.69, 95% CI: 1.30–2.19) and suicide plan (OR: 1.76, 95% CI: 1.34–2.33) compared with adolescents who meet all the recommendations. Soft drink consumption of ≥3 times/day was associated with an increased risk of suicidality including suicidal ideation, suicide plan, suicide attempt, and suicide attempt with medical treatment, regardless of sex. Soft drink consumption of ≥3 times/day was significantly associated with an increased risk of suicide attempt and suicide attempt with medical treatment, regardless of whether the recommendations of physical activity, screen time, and sleep duration were met. Conclusion: Age-appropriate sleep duration, no more than 2 h of screen time per day, at least 1 h of physical activity per day as contained in the 24 h movement guidelines and less than one soft drink consumption per day are good targets to prevent involvement in suicidality. More actions for intervening in the movement and dietary behaviors among adolescents are needed to maintain physical and mental health.     

24-hour movement guideline adherence and mental health: A cross-sectional study of emerging adults with chronic health conditions and disabilities

BackgroundRecent work has shown that individuals with chronic health conditions and disabilities (CCD) meet the 24-h movement guidelines at lower rates than population norms; however, the evidence base remains limited across different stages of the lifespan and very few studies have examined associations with mental health outcomes.ObjectiveThis study examined 24-h movement guideline adherence among emerging adults with CCD compared to those without and associations between guideline adherence and indicators of mental health.MethodsThis cross-sectional study used data from the 2020 cycle of the Canadian Campus Wellbeing Survey. A total of 17,874 emerging adults enrolled at 20 post-secondary institutions (mean age = 21.6 ± 2.94 years; 65.2% female), including 3336 who identified with a CCD, self-reported their movement behaviors (physical activity, sedentary behaviors, sleep) and completed measures of psychological distress and mental well-being. Logistic regressions models were computed to examine differences in guideline adherence. Propensity score weighted linear regression models were computed to examine associations between guideline adherence and indicators of mental health.ResultsEmerging adults with CCD had significantly lower odds of meeting the 24-h movement guidelines than their peers, and disparities in guideline adherence were most pronounced among those with multimorbidity, developmental, and physical disabilities. Guideline adherence was associated with significantly more favorable scores for psychological distress and mental well-being among those with and without CCD.ConclusionsFindings suggest emerging adults with CCD engage in less healthy movement behavior patterns than their peers, yet they appear to experience similar mental health benefits when they do meet the 24-h movement guidelines.     

Patient and clinician factors associated with uptake of the human papillomavirus (HPV) vaccine among adolescent patients of a primary care network

BackgroundHuman papillomavirus (HPV) vaccination rates for adolescents remain relatively low. The purpose of this study is to examine patient and clinician factors associated with HPV vaccination among patients, ages 11–17, of a large community-based primary care network.MethodsElectronic health records and administrative data from a large primary care network from January 2017 – June 2018 for patients ages 11–17 (n = 10,682) and the 198 primary care clinicians that saw them were analyzed. Mixed effects logistic regression models examined the association of patient and clinician factors with HPV vaccine uptake.ResultsMost patients (63.0%) had at least one dose of the HPV vaccine, and 37.7% were up to date. In adjusted analyses, patients who received the tetanus, diphtheria, and pertussis (Tdap) vaccine (OR = 2.8, 95% CI: 2.1–3.9) compared to those who did not receive the vaccine and patients with five or more medical visits (OR = 1.9, 95% CI: 1.6–2.2) had the greatest odds of being up to date with the HPV vaccine series. Compared to White patients, African American/Black (OR = 0.8, 95% CI: 0.6 – 1.0) and Alaskan Native/American Indian (OR = 0.5, 95% CI: 0.3–0.9) patients were less likely to be up to date. Boys were also less likely to be up to date with the HPV vaccine series compared to girls (OR = 0.7, 95% CI: 0.7–0.8). Additionally, patients with family/general practice primary care clinicians were less likely to have their patients up to date than those with pediatricians (OR = 0.8, 95% CI: 0.6 – 1.0).ConclusionHPV vaccine uptake varied by patient characteristics, heath care utilization and primary care clinician specialty. These findings may inform future evidence-based interventions aimed at increasing HPV vaccine uptake among adolescents by targeting patient sub-groups and reducing missed opportunities for vaccination.     

Population immunity to measles in Canada using Canadian Health Measures survey data – A Canadian Immunization Research Network (CIRN) study

We aimed to determine population immunity to measles in Canada, and to assess the risk of future outbreaks. We tested 11,176 sera from Cycles 2 (2009–2011) and 3 (2011–2013) cohorts from the biobank of Statistics Canada’s Canadian Health Measures Survey (CHMS) using the BioPlex 2220 MMRV IgG assay. We then tested all BioPlex negative and equivocal samples using a more sensitive Plaque Reduction Neutralization Test (PRNT). We determined the weighted proportion of positive, equivocal, and negative samples by age, sex, region and whether individuals were born in Canada. We found that 90.0% (95% confidence interval (CI): 88.2, 91.9) of samples were positive, 4.5% (95% CI: 3.4, 5.5) were equivocal and 5.5% (95% CI: 4.3, 6.7) were negative. Individuals in the 12–19 year age band had the lowest proportion positive at 78.7% (95% CI: 74.2, 83.2) and the highest proportion of positive samples was found in those 60–79 years (99.6%, 95% CI: 99.3, 99.9). Seropositivity was consistently <90% across a broad range of pediatric and adult age bands (6–39 years). We found that a slightly higher proportion of females were positive (91.9%, 95% CI: 90.1, 93.6) compared to males (88.3%, 95% CI: 85.8, 90.7). When taking into account interaction between age and born in Canada status, we found individuals born in Canada aged 19 and under were less susceptible (OR = 0.6 (95% CI: 0.4, 0.95)) compared to those born outside Canada whereas, those aged 20 and over were more susceptible (OR = 1.7 (95% CI: 1.1, 2.8)). Our findings indicate that measles immunity in Canada is below the 95% immunity threshold required to sustain measles elimination, underscoring the importance of maintaining high vaccine coverage to prevent future measles outbreaks and sustain Canada’s elimination status.     

Precarious employment and the risk of suicidal ideation and suicide attempts

ObjectiveAlthough the effect of occupation or employment status on suicide risk is notable, there are few studies on the effect of precarious employment on suicide. We compared suicidal ideation and suicide attempts in precarious workers and their non-precarious counterparts using a representative sample from South Korea.MethodThe 2008 Korean Community Health Survey data were used for this study. Information was obtained on 52,161 participants (41,063 employees with non-precarious work and 11,098 employees with precarious work). The outcome of the logistic regression model was the presence of suicidal thoughts and attempts, and the independent variables were the demographics, socioeconomic status, and health status.ResultsEmployees with precarious work were more likely to exhibit suicidal ideation (OR = 1.41; 95% CI, 1.28–1.55) and suicide attempts (OR = 1.52; 95% CI, 1.02–2.27) than employees with non-precarious work. After controlling for income and education (Model 2) depressive feelings (Model 6), compared with unadjusted model, remained significant but the odds ratio was largely attenuated, indicating a strong association between suicidal risk and socioeconomic and feelings of depression.ConclusionPrecarious workers had a higher risk of suicidal ideation and suicide attempts than non-precarious workers. Our study suggests that precarious employment is an important risk for suicide.     

Social and demographic patterns of influenza vaccination coverage in Norway,influenza seasons 2014/15 to 2020/21

AimsTo examine influenza vaccination coverage among risk groups (RG) and health care workers (HCW), and study social and demographic patterns of vaccination coverage over time.MethodsVaccination coverage was estimated by self-report in a nationally representative telephone survey among 14 919 individuals aged 18–79 years over seven influenza seasons from 2014/15 to 2020/21. We explored whether belonging to an influenza RG (being >=65 years of age and/or having >=1 medical risk factor), being a HCW or educational attainment was associated with vaccination status using logistic regression.ResultsVaccination coverage increased from 27 % to 66 % among individuals 65–79 years, from 13 % to 33 % among individuals 18–64 years with >=1 risk factor, and from 9 % to 51 % among HCWs during the study period. Being older, having a risk factor or being a HCW were significantly associated with higher coverage in all multivariable logistic regression analyses. Higher education was also consistently associated with higher coverage, but the difference did not reach significance in all influenza seasons. Educational attainment was not significantly associated with coverage while coverage was at its lowest (2014/15–2017/18), but as coverage increased, so did the differences. Individuals with intermediate or lower education were less likely to report vaccination than those with higher education in season 2018/19, OR = 0.61 (95 % CI 0.46–0.80) and OR = 0.58 (95 % CI 0.41–0.83), respectively, and in season 2019/20, OR = 0.69 (95 % CI 0.55–0.88) and OR = 0.71 (95 % CI 0.53–0.95), respectively. When the vaccine was funded in the COVID-19 pandemic winter of 2020/21, educational differences diminished again and were no longer significant.ConclusionsWe observed widening educational differences in influenza vaccination coverage as coverage increased from 2014/15 to 2019/20. When influenza vaccination was funded in 2020/21, differences in coverage by educational attainment diminished. These findings indicate that economic barriers influence influenza vaccination decisions among risk groups in Norway.     

Food Addiction and Lifestyle Habits among University Students

The prevalence of overweight and obesity is increasing in our society, with a complex, multifactorial origin, and associated with greater morbidity and mortality in the population. Food addiction (FA) is a common disorder in overweight/obese people, which appears to be increasingly common in young people. This study analyzed food addiction in a group of young university students and to examine its association with body composition, quality of sleep, adherence to the Mediterranean diet, physical activity/sedentary habits, tobacco or alcohol consumption, and health status. A total of 536 undergraduate nursing students participated in a questionnaire that included the Yale Food Addiction Scale (YFAS 2.0). Up to 6.4% of the students presented FA. Statistically significant associations were observed in the variables for sleep quality odds ratio (OR) 4.8 (95% confidence interval (CI): 1.66–13.87), anxiety/depression OR 8.71 (95% CI: 3.93–19.27), body mass index (BMI) OR 8.32 (95% CI: 3.81–18.15) and sedentary lifestyle OR 2.33 (95% CI: 1.09–5.01). A predictive model was developed after binary logistic regression (area under the ROC curve 0.84 (95% CI: 0.77–0.91). Students with FA presented higher BMI values, worse sleep quality, anxiety or depression problems, and more time spent in sedentary behaviors.     

童年期虐待的不同形式与中学生自杀行为关联性研究

目的 探讨不同形式的童年期虐待与中学生自杀行为的关系。方法 采用分层整群抽样的方法,以广州、新乡、沈阳和重庆4个地区14221名中学生为研究对象,使用问卷调查了解一般人口统计学指标、心理问题症状、童年期虐待经历及自杀行为等信息,建立多因素logistic回归模型,分析不同形式的童年期虐待对自杀行为发生的影响。结果 中学生童年期总体虐待、躯体虐待、情感虐待、性虐待、自杀意念、自杀计划和自杀未遂的检出人数(率)分别为7246(51.0%)、5824(41.0%)、5409(38.0%)、1039(7.3%)、2042(14.4%)、1174(8.3%)和548(3.9%)。男生躯体虐待的检出率高于女生,女生情感虐待和自杀意念的检出率高于男生,组间差异有统计学意义(P<0.01);童年期性虐待、自杀计划和自杀未遂的检出率在不同性别间的差异无统计学意义(P>0.01)。控制相关混杂因素的作用后,童年期虐待经历会增加男生自杀意念(OR=2.03,95%CI:1.72~2.40)和自杀计划(OR=1.93,95%CI:1.57~2.37)的发生风险,增加女生自杀意念(OR=2.45,95%CI:2.12~2.82)、自杀计划(OR=2.46,95%CI:2.02~3.00)和自杀未遂(OR=2.12,95%CI:1.61~2.78)的发生风险。除童年期躯体虐待与男生自杀未遂外,不同类型的童年期虐待均是男女中学生自杀行为发生的危险因素(P<0.01)。随着童年期虐待种类数的增加,男女生自杀行为的发生风险亦呈增高趋势(P<0.01)。持续受虐以及施虐人为父母/其他的中学生,自杀行为的发生风险显著增加。结论 童年期虐待经历是中学生自杀行为发生的重要危险因素。
