Abstract Aims Cognitive deficits are an important factor in the pathogenesis of psychosis. Subjective cognitive complaints (SCCs) are often considered to be a precursor of objective cognitive deficits, but there are no studies specifically on SCC and psychotic experiences (PE). Thus, we assessed the association between SCC and PE using data from 48 low- and middle-income countries. Methods Community-based cross-sectional data of the World Health Survey were analysed. Two questions on subjective memory and learning complaints in the past 30 days were used to create a SCC scale ranging from 0 to 10 with higher scores representing more severe SCC. The Composite International Diagnostic Interview was used to identify past 12-month PE. Multivariable logistic regression and mediation analyses were performed. Results The final sample consisted of 224 842 adults aged ⩾18 years [mean (SD) age 38.3 (16.0) years; 49.3% males]. After adjustment for sociodemographic factors, a one-unit increase in the SCC scale was associated with a 1.17 (95% CI 1.16–1.18) times higher odds for PE in the overall sample, with this association being more pronounced in younger individuals: age 18–44 years OR = 1.19 (95% CI 1.17–1.20); 45–64 years OR = 1.15 (95% CI 1.12–1.17); ⩾65 years OR = 1.14 (95% CI 1.09–1.19). Collectively, other mental health conditions (perceived stress, depression, anxiety, sleep problems) explained 43.4% of this association, and chronic physical conditions partially explained the association but to a lesser extent (11.8%). Conclusions SCC were associated with PE. Future longitudinal studies are needed to understand temporal associations and causal inferences, while the utility of SCC as a risk marker for psychosis especially for young adults should be scrutinised.

Background: The effect of weight modification on future dementia risk is currently a subject of debate and may be modified by age. Objective: The aim of the present study was to investigate the association between body mass index (BMI) status with mild cognitive impairment (MCI) (a preclinical stage of dementia) in middle-aged and older adults residing in six low- and middle-income countries using nationally representative data. Methods: Cross-sectional data from the Study on Global Ageing and Adult Health (SAGE) were analyzed. MCI was defined using the National Institute on Aging-Alzheimer’s Association criteria. BMI (kg/m2) was based on measured weight and height and categorized as: underweight (<18.5), normal (18.5–24.9), overweight (25.0–29.9), and obese (≥30.0). Multivariable logistic regression analysis and meta-analysis were conducted to assess associations. Results: Data on 32,715 individuals aged ≥50 years with preservation in functional abilities were analyzed [mean (SD) age 62.1 (15.6) years; 51.7% females]. Among those aged 50–64 years, compared to normal weight, underweight (OR = 1.44; 95% CI = 1.14–1.81), overweight (OR = 1.17; 95% CI = 1.002–1.37), and obesity (OR = 1.46; 95% CI = 1.09–1.94) were all significantly associated with higher odds for MCI. In those aged ≥65 years, underweight (OR = 0.71; 95% CI = 0.54–0.95) and overweight (OR = 0.72; 95% CI = 0.55–0.94) were associated with significantly lower odds for MCI, while obesity was not significantly associated with MCI. Conclusion: The results of the study suggest that the association between BMI and MCI is likely moderated by age. Future longitudinal studies are required to confirm or refute the present findings before recommendations for policy and practice can be made.

We investigated physical activity (PA) correlates among middle-aged and older adults (aged ≥50 years) with hazardous drinking patterns in six low- and middle-income countries. Cross-sectional data were analyzed from the World Health Organization’s Study on Global Ageing and Adult Health. Hazardous drinking was defined as consuming >7 (females) or >14 (males) standard drinks per week. Participants were dichotomized into low (i.e., not meeting 150 min of moderate PA/week) and moderate–high physically active groups. Associations between PA and a range of correlates were examined using multivariable logistic regressions. The prevalence of low PA in 1,835 hazardous drinkers (60.5 ± 13.1 years; 87.9% males) was 16.2% (95% confidence interval [13.9%, 18.9%]). Older age, living in an urban setting, being unemployed, depression, underweight, obesity, asthma, visual impairment, poor self-rated health, and higher levels of disability were identified as significant PA correlates. The current data provide important guidance for future interventions to assist older hazardous drinkers to engage in regular PA.
