The purpose of this study to analyse whether compulsive buying in teenagers is related to gender and alcohol and cannabis use in a sample of 573 students aged 14–17 from secondary education schools in Burgos (Spain) (M = 15.65; SD = 1.04). Random cluster sampling was performed to select the sample. The Compulsive Buying Questionnaire was used together with two extra promts: ‘Indicate how much alcohol you consume’ and ‘Indicate how much cannabis you take’. Descriptive statistics were used in data analysis, while MANOVA was used to study gender differences in alcohol and cannabis use, compulsive buying and their interaction. The results show higher scores for female compulsive buyers than for men, higher scores for alcohol and cannabis users’ compulsive buying than for non-users, respectively, and higher scores for female users than for male users. A certain interaction was also observed between alcohol and cannabis use. A higher alcohol consumption entailed a higher score in compulsive buying, with cannabis users who did not consume alcohol obtaining the highest scores. Thus, prevention programmes should consider teenagers’ gender and the risk of taking toxic substances.

AimsTo investigate the prevalence and incidence of presbyopia in an urban Chinese population.Methods1817 subjects aged ≥35 years were identified by random cluster sampling in Yuexiu District, Guangzhou, China, at baseline in 2008, and all were invited for the follow-up examination in 2014. Distance and near visual acuity (VA) tests, as well as non-cycloplegic automated refraction were performed at each examination as per standardised protocol. Participants with presenting near VA ≤20/40 were further tested with add power at a standard distance of 40 cm to obtain their best-corrected near VA. Functional presbyopia was defined as near VA under presenting distance refraction correction of <20/50 and could be improved by at least one line with add power.ResultsA total of 1191 (83.5% of the 2014 follow-up) participants were included in the current analysis with a mean (SD) age of 50.4 (9.7) years, and 52.9% were female. Prevalence of functional presbyopia at baseline was 25.2% (95% CI 21.5 to 28.9) and the 6-year incidence was 42.8% (95% CI 39.4 to 50.1). Older and more hyperopic subjects had both higher prevalence and incidence of presbyopia (P<0.001). Average presbyopic correction coverage (PCC) was 87.7% at baseline and was significantly lower in myopic participants (P=0.006).ConclusionsPrevalence of functional presbyopia in urban China is relatively lower along with a higher PCC compared with previous population-based rural cohorts. We identified a high presbyopia incidence, and further studies are needed to understand longitudinal presbyopia progression as well as the urban–rural gap in presbyopia to throw light on future strategic planning.

Objective: Moving Shapes paradigm is a test that evaluates intentionality as a theory of mind (ToM) component. This study aimed to assess the normative data and reliability of this test in a community sample of 9-11-year-old children. Method: A total of 398 children aged between 9 and 11 years were recruited from mainstream elementary schools through a random cluster sampling. All participants were evaluated using the Moving Shapes paradigm. To evaluate test-retest reliability, the test was administered again after 2-4 weeks. Results: The intentionality mean score was 29.70 (+5.88) out of 60. There was no significant difference between girls and boys in test scores. Age was not significantly related to the paradigm variables scores. Ten percent of the participants achieved the scores below 22, and 10% above 37. Cronbach’s Alfa was 0.40 for the intentionality score. The test-retest reliability was fair to good (0.43 - 0.79) for different groups of animations. The inter-rater agreement was 80%. Conclusion: The study found that the Moving shapes paradigm is a reliable instrument to evaluate intentionality in normal school-aged children.
