Objective:
A commonly used confrontation naming task used in the United States is The Boston Naming Test (BNT). Performance differences has been found in Caucasian and ethnic minorities on the BNT. The Cordoba Naming Test (CNT) is a 30-item confrontation naming task developed in Argentina. Past research has shown acculturation levels can influence cognitive performance. Furthermore, one study evaluated geriatric gender differences on CNT performance in Spanish. Researchers reported that older male participants outperformed female participants on the CNT. To our knowledge, researchers have not evaluated ethnic differences on the CNT using a geriatric sample. The purpose of the present study was to examined CNT performance and acculturation in a Latinx and Caucasian geriatric sample. It was predicted the Caucasian group would outperform the Latinx group on the CNT. Moreover, the Caucasian group would report higher acculturation levels on the Abbreviated Multidimensional Acculturation Scale (AMAS) compared to the Latinx group.
Participants and Methods:The sample consisted of 9 Latinx and 11 Caucasian participants with a mean age of 66.80 (SD =6.10), with an average of 14.30 (SD = 2.00) years of education. All participants were neurologically and psychologically healthy and completed the CNT and the AMAS in English. Acculturation was measured via the AMAS English subscales (i.e., English Language, United States. Identity, United States, Competency). A series of ANCOVAs, controlling for years of education completed and gender, was used to evaluate CNT performance and acculturation.
Results:The ethnic groups were not well demographically matched (i.e., years of education and gender).We found that the Caucasian group outperformed the Latinx group on CNT performance p = .012, ηp 2 = .34. Furthermore, the Caucasian group reported higher acculturation levels (i.e., English Language, United States, Identity, United States, Competency) compared to the Latinx group p’s < .05, ηps2 = .42-.64.
Conclusions:To our knowledge, this is the first study to evaluate CNT performance between ethnic groups with a geriatric sample. As expected the Caucasian group outperformed the Latinx group on the CNT. Also, as expected the Caucasian group reported higher English acculturation levels compared to the Latinx group. Our findings are consistent with past studies showing ethnic differences on confrontational naming performance (i.e., The Boston Naming Test), favoring Caucasians. A possible explanation for group differences could have been linguistic factors (e.g., speaking multiple languages) in our Latinx group. Therefore, since our Latinx group reported lower levels of English Language, United States identity, and United States competency the Latinx group assimilation towards United States culture might of influence their CNT performance. Future studies with different ethnic groups (e.g., African-Americans) and a larger sample size should examine if ethnic differences continue to cross-validate in a geriatric sample.

Introduction
School-based interventions to prevent obesity have shown heterogeneous results. Recent school-based trials with “negative” have cast doubt on their effectiveness. In the Juntos Santiago trial, we used an innovative, theory-based gamification strategy to increase motivation and participation in healthy behavioural changes. This is the first trial, to our knowledge, to use gamification to prevent childhood obesity.
ObjectiveTo examine the effectiveness of a multicomponent gamification strategy to prevent obesity in 5th and 6th-grade schoolchildren in Santiago de Chile.
Materials and methodsSchool-based, parallel cluster-randomized controlled trial. 81 schools in two municipalities in Santiago, Chile, with more than 40 students in 5th and 6th grade altogether were eligible. Schools were randomized and sequentially invited to participate. The multicomponent intervention was a gamification strategy with four components: (i) healthy challenges (snacks, steps and healthy activities); (ii) gamification incentives, such as points, levels, leaderboards and badges; (iii) rewards (infrastructure and fun activity) and (iv) an online platform for parents and students to monitor the progress. Participants were followed up at 5 and 8 months. Pre-registered primary outcomes were body mass index (BMI) z-score and waist circumference (WC) at 8 months. Secondary outcomes were BMI and systolic (SBP) and diastolic blood pressure (DBP) at 8 months. Multilevel analysis adjusted for individual and school-level covariates were used.
Results24 schools (9 controls) and 2333 students (709 controls) were assessed at baseline and 2264 students (689 controls) were assessed at 8 months. The mean BMI z-score was lower in the intervention group compared to the control group at 8 months (mean difference -0.132, 95% CI -0.249; -0.014), while no difference was observed for WC. Mean BMI and SBP were lower in the intervention arm compared to the control arm (mean difference for SBP -0.139; 95% CI -2.39; -0.40). No difference was observed for DBP.
DiscussionThe gamification strategy appears to prevent childhood obesity and reduce systolic blood pressure in school children in Santiago. These effects are larger than the pooled effects from existing meta-analyses. Further research should identify which components of the gamification strategy were more effective.
