- Stress has a central role in most theories of psychosis etiology, but the relation between stress and psychosis has rarely been examined in large population-level data sets, particularly in low- and middle-income countries. We used data from 39 countries in the World Health Survey (n = 176 934) to test the hypothesis that stress sensitivity would be associated with psychotic experiences, using logistic regression analyses. Respondents in low-income countries reported higher stress sensitivity (P < .001) and prevalence of psychotic experiences (P < .001), compared to individuals in middle-income countries. Greater stress sensitivity was associated with increased odds for psychotic experiences, even when adjusted for co-occurring anxiety and depressive symptoms: adjusted odds ratio (95% CI) = 1.17 (1.15-1.19) per unit increase in stress sensitivity (range 2-10). This association was consistent and significant across nearly every country studied, and translated into a difference in psychotic experience prevalence ranging from 6.4% among those with the lowest levels of stress sensitivity up to 22.2% among those with the highest levels. These findings highlight the generalizability of the association between psychosis and stress sensitivity in the largest and most globally representative community-level sample to date, and support the targeting of stress sensitivity as a potential component of individual- and population-level interventions for psychosis.

- Background: Alcohol use is a leading risk factor for death and disability, but its overall association with health remains complex given the possible protective effects of moderate alcohol consumption on some conditions. With our comprehensive approach to health accounting within the Global Burden of Diseases, Injuries, and Risk Factors Study 2016, we generated improved estimates of alcohol use and alcohol-attributable deaths and disability-adjusted life-years (DALYs) for 195 locations from 1990 to 2016, for both sexes and for 5-year age groups between the ages of 15 years and 95 years and older.Methods: Using 694 data sources of individual and population-level alcohol consumption, along with 592 prospective and retrospective studies on the risk of alcohol use, we produced estimates of the prevalence of current drinking, abstention, the distribution of alcohol consumption among current drinkers in standard drinks daily (defined as 10 g of pure ethyl alcohol), and alcohol-attributable deaths and DALYs. We made several methodological improvements compared with previous estimates: first, we adjusted alcohol sales estimates to take into account tourist and unrecorded consumption; second, we did a new meta-analysis of relative risks for 23 health outcomes associated with alcohol use; and third, we developed a new method to quantify the level of alcohol consumption that minimises the overall risk to individual health.Findings: Globally, alcohol use was the seventh leading risk factor for both deaths and DALYs in 2016, accounting for 2.2% (95% uncertainty interval [UI] 1.5-3.0) of age-standardised female deaths and 6.8% (5.8-8.0) of age-standardised male deaths. Among the population aged 15-49 years, alcohol use was the leading risk factor globally in 2016, with 3.8% (95% UI 3.2-4-3) of female deaths and 12.2% (10.8-13-6) of male deaths attributable to alcohol use. For the population aged 15-49 years, female attributable DALYs were 2.3% (95% UI 2.0-2.6) and male attributable DALYs were 8.9% (7.8-9.9). The three leading causes of attributable deaths in this age group were tuberculosis (1.4% [95% UI 1. 0-1. 7] of total deaths), road injuries (1.2% [0.7-1.9]), and self-harm (1.1% [0.6-1.5]). For populations aged 50 years and older, cancers accounted for a large proportion of total alcohol-attributable deaths in 2016, constituting 27.1% (95% UI 21.2-33.3) of total alcohol-attributable female deaths and 18.9% (15.3-22.6) of male deaths. The level of alcohol consumption that minimised harm across health outcomes was zero (95% UI 0.0-0.8) standard drinks per week.Interpretation: Alcohol use is a leading risk factor for global disease burden and causes substantial health loss. We found that the risk of all-cause mortality, and of cancers specifically, rises with increasing levels of consumption, and the level of consumption that minimises health loss is zero. These results suggest that alcohol control policies might need to be revised worldwide, refocusing on efforts to lower overall population-level consumption.

- Background and AimsAlthough gout is one of the most common rheumatic diseases, world data are lacking because most studies have focused on industrialized countries. Therefore, we aimed to investigate the global burden of gout and its associations with the year of diagnosis, age, geographical region, sociodemographic status and various further risk factors. MethodsRetrospective data from the Global Burden of Disease (GBD) were used, initially collected between 1990 and 2019. Raw numbers and age-standardized rates (per 100,000 persons) of prevalence, incidence and years lived with disability (YLDs) of gout were extracted from GBD 2019 for 204 countries and territories and stratified by sex, age, year, sociodemographic index and geographic region. Correlations between gout and other chronic diseases were identified, and the burden attributable to high body mass index (BMI) and kidney dysfunction was described. ResultsThe total number of patients and gout age-standardized prevalence rate increased between 1990 and 2019. Gout was most prevalent in Australasia and high-income North America, and a higher sociodemographic index (SDI) was associated with higher age-standardized prevalence, incidence and YLDs. High BMI and kidney dysfunction were risk factors for gout, while gout was correlated with other kidney diseases. ConclusionsThe global prevalence of gout, as well as incidence, and YLDs increased worldwide from 1990 to 2019 and had a significant association with sex, age, geographic region, SDI and risk factors. Understanding the complex interplay of environmental, sociodemographic and geographic risk factors is essential in mitigating the ever-rising disease burden of gout.

- We performed an umbrella review on environmental risk/protective factors and biomarkers for postpartum depressive symptoms to establish a hierarchy of evidence. We systematically searched PubMed, Embase, and the Cochrane Database of Systematic Reviews from inception until 12 January 2021. We included systematic reviews providing meta-analyses related to our research objectives. Methodological quality was assessed by AMSTAR 2, and the certainty of evidence was evaluated by GRADE. This review was registered in PROSPERO (CRD42021230784). We identified 30 articles, which included 45 environmental risk/protective factors (154594 cases, 7302273 population) and 9 biomarkers (2018 cases, 16757 population). The credibility of evidence was convincing (class I) for antenatal anxiety (OR 2.49, 1.91-3.25) and psychological violence (OR 1.93, 1.54-2.42); and highly suggestive (class II) for intimate partner violence experience (OR 2.86, 2.12-3.87), intimate partner violence during pregnancy (RR 2.81, 2.11-3.74), smoking during pregnancy (OR 2.39, 1.78-3.2), history of premenstrual syndrome (OR 2.2, 1.81-2.68), any type of violence experience (OR 2.04, 1.72-2.41), primiparity compared to multiparity (RR 1.76, 1.59-1.96), and unintended pregnancy (OR 1.53, 1.35-1.75).

- BACKGROUND: Data on the association between overweight/obesity and bullying victimization among adolescents are scarce from low- and middle-income countries.OBJECTIVES: We assessed the associations between overweight/obesity and bullying victimization in 41 low- and middle-income countries.METHODS: Cross-sectional data from the Global School-based Student Health Survey were analysed. Data on past 30-day bullying victimization (including type) and body mass index based on measured weight and height were collected. The 2007 WHO Child Growth reference was used to define overweight and obesity. Multivariable logistic regression (multinomial and binary) and meta-analyses based on country-wise estimates were conducted. Data on 114 240 adolescents aged 12 to 15 years were analysed (mean age [SD], 13.8 [1.0] y; 48.8% girls).RESULTS: Among girls, compared with normal weight, overweight (OR = 1.08; 95% CI, 1.02-1.16; between-country heterogeneity I2 = 0.0%) and obesity (OR = 1.20; 95% CI, 1.07-1.34; I2 = 0.0%) were associated with significantly higher odds for any bullying victimization, but no significant association was observed among boys. However, overweight and obesity were both associated with significantly increased odds for bullying by being made fun of because of physical appearance among both sexes-obesity (vs normal weight): girls OR = 3.42 (95% CI, 2.49-4.71); boys OR = 2.38 (95% CI, 1.67-3.37).CONCLUSIONS: Effective strategies to reduce bullying of children with overweight/obesity are needed in low- and middle-income countries.

- OBJECTIVES: To assess the association between chronic physical conditions and multimorbidity and mild cognitive impairment (MCI) in low- and middle-income countries (LMICs).DESIGN: Nationally representative, cross-sectional, community-based study.SETTING: Six countries that participated in the World Health Organization Study on Global Ageing and Adult Health.PARTICIPANTS: Individuals aged 50 and older (N=32,715; mean age 62.1 ± 15.6; 51.7% female).MEASUREMENTS: The definition of MCI was based on the recommendations of the National Institute on Ageing and Alzheimer's Association. Ten chronic conditions were assessed (angina pectoris, arthritis, asthma, cataract, chronic lung disease, diabetes mellitus, edentulism, hearing problems, hypertension, stroke). Multivariable logistic regression analysis was conducted to assess the association between chronic physical conditions, multimorbidity (≥2 chronic conditions), and MCI.RESULTS: The prevalence of multimorbidity was 49.8% (95% confidence interval (CI)=48.1-51.5%) and of MCI was 15.3% (95% CI=14.4-16.3%). After adjustment for potential confounders, edentulism (odds ratio (OR)=1.24), arthritis (OR=1.24), chronic lung disease (OR=1.29), cataract (OR=1.33), stroke (OR=1.94), hearing problems (OR=2.27), and multimorbidity (OR=1.40) were significantly associated with MCI. There was a gradual increase in the likelihood of MCI (1 condition: OR=1.21, 95% CI=1.03-1.42; ≥4 conditions: OR=2.07, 95% CI=1.70-2.52).CONCLUSION: These results highlight the need to investigate the underlying mechanisms linking chronic conditions and MCI and whether prevention or treatment of chronic conditions or multimorbidity can reduce the onset of cognitive decline and subsequent dementia, especially in LMICs.

- There are no studies on the association between food insecurity and mild cognitive impairment (MCI). Thus, cross-sectional, community-based data on individuals aged ≥50 years from the World Health Organization's Study on Global AGEing and Adult Health (SAGE) conducted in South Africa (2007⁻2008) were analyzed to assess this association. The definition of MCI was based on the National Institute on Ageing-Alzheimer's Association criteria. Past 12-month food insecurity was assessed with two questions on frequency of eating less and hunger due to lack of food. Multivariable logistic regression analysis was conducted. The sample consisted of 3,672 individuals aged ≥50 years [mean (SD) age 61.4 (18.3); 56% females]. The prevalence of MCI was 8.5%, while 11.0% and 20.8% experienced moderate and severe food insecurity, respectively. After adjustment for potential confounders, moderate and severe food insecurity were associated with 2.82 (95%CI = 1.65⁻4.84) and 2.51 (95%CI = 1.63⁻3.87) times higher odds for MCI compared with no food insecurity, respectively. The OR for those aged ≥65 years with severe food insecurity was particularly high (OR = 3.87; 95%CI = 2.20⁻6.81). In conclusion, food insecurity was strongly associated with MCI among South African older adults. Future longitudinal research is required to assess whether addressing food insecurity may reduce risk of MCI and subsequent dementia.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Little is known about the association between psychotic-like experiences (PLEs) and nonsuicidal self-injury (NSSI) in the general adult population. Thus, the aim of this study was to examine the association using nationally-representative data from England.METHODS: Data from the 2007 Adult Psychiatric Morbidity Survey was analyzed. The sample consisted of 7403 adults aged ≥16 years. Five forms of PLEs (mania/hypomania, thought control, paranoia, strange experience, auditory hallucination) were assessed with the Psychosis Screening Questionnaire. The association between PLEs and NSSI was assessed by multivariable logistic regression. Hierarchical models were constructed to evaluate the influence of alcohol and drug dependence, common mental disorders, and borderline personality disorder symptoms on this association.RESULTS: The prevalence of NSSI was 4.7% (female 5.2% and male 4.2%), while the figures among those with and without any PLEs were 19.2% and 3.9% respectively. In a regression model adjusted for sociodemographic factors and stressful life events, most types of PLE were significantly associated with NSSI: paranoia (OR 3.57; 95%CI 1.96-6.52), thought control (OR 2.45; 95%CI 1.05-5.74), strange experience (OR 3.13; 95%CI 1.99-4.93), auditory hallucination (OR 4.03; 95%CI 1.56-10.42), and any PLE (OR 2.78; 95%CI 1.88-4.11). The inclusion of borderline personality disorder symptoms in the models had a strong influence on the association between PLEs and NSSI as evidenced by a large attenuation in the ORs for PLEs, with only paranoia continuing to be significantly associated with NSSI. Substance dependence and common mental disorders had little influence on the association between PLEs and NSSI.CONCLUSIONS: Borderline personality disorder symptoms may be an important factor in the link between PLEs and NSSI. Future studies on PLEs and NSSI should take these symptoms into account.

- Background Sibship size and birth order may be contributing factors to the multifactorial etiology of psychosis. Specifically, several studies have shown that sibship size and birth order are associated with schizophrenia. However, there are no studies on their association with psychotic experiences (PE). Methods Cross-sectional, community-based data from 43 low- and middle-income countries which participated in the World Health Survey were analyzed. The Composite International Diagnostic Interview was used to identify four types of past 12-month PE. The association of sibship size and birth order with PE was assessed with multivariable logistic regression. Results The final sample consisted of 212,920 adults [mean (SD) age 38.1 (16.0) years; 50.7% females]. In the multivariable analysis, compared to individuals with no siblings, the OR increased linearly from 1.26 (95%CI = 1.01–1.56) to 1.72 (95%CI = 1.41–2.09) among those with 1 and ≥ 9 siblings, respectively. Compared to the first-born, middle-born individuals were more likely to have PE when having a very high number of siblings (i.e. ≥9). Conclusions Future studies should examine the environmental and biological factors underlying the association between sibship size/birth order and PE. Specifically, it may be important to examine the unmeasured factors, such as childhood infections and adversities that may be related to both family structure and PE.

- Previous studies examining the association between schizophrenia and pain have produced mixed results and data on sub-threshold psychosis or psychotic symptoms and pain are scarce. This study assessed the association between psychosis and severe pain among community-dwelling adults in 44 low- and middle-income countries (LMICs) where no data exists.Data on 235,370 adults aged ≥18 years from the World Health Survey (WHS) 2002-2004 were analyzed. The presence of past 12-month psychotic symptoms was established using four questions from the Composite International Diagnostic Interview. Participants were categorized into four mutually exclusive groups based on whether they had at least one psychotic symptom and/or a lifetime psychosis or schizophrenia diagnosis. Multivariable logistic regression was used to estimate the association between psychosis and past 30-day severe pain. The prevalence of severe pain among those with 0, 1, 2, ≥3 psychotic symptoms was 8.7%, 16.7%, 21.8%, 30.5% respectively. Compared to those with no psychotic symptoms or diagnosis, the ORs (95%CIs) were: at least one symptom without diagnosis [2.17 (1.99-2.38)]; no symptom with diagnosis [2.33 (1.71-3.17)]; at least one symptom and diagnosis [4.27 (3.20-5.71)]. Associations were partly mediated by chronic physical conditions, anxiety, and depression. Despite some limitations such as the use of a single-item question to assess pain, the results of this study suggest that individuals with psychotic symptoms or a psychosis diagnosis should be systematically assessed for pain, and if necessary, receive treatment for pain and its underlying conditions. Future research on the effect of pain management on psychosis outcome is warranted.
