Global trends in dementia care research in the context of COVID-19: bibliometric analysis.

Alzheimer's disease is the most common type of dementia, producing a deterioration in the activities of daily living which can lead to the need for care provision. COVID-19 impacted their quality of life and in this care delivery. This study aimed to analyse most productive and prominent authors, the journals and countries with the highest number of publications, the most cited documents and the most used keywords. Publications were retrieved from journals indexed in the Main Collection of the Web of Science (WoS) and analysed using the traditional laws of bibliometrics. A total of 376 documents were found. The WoS categories with the highest number of publications accumulated were "Geriatric Gerontology" and "Gerontology." Clarissa Giebel was the most productive (23 papers) and most cited (with 569 citations) co-author. The Journal of Alzheimer's Disease (21 papers) published the most number of documents. The manuscript "2021 Alzheimer's Disease Facts and Figures" was the most cited. Four thematic clusters related to mental health, telemedicine, care and well-being were found among the authors' keywords. Research networks exist worldwide, with the United States of America and England leading the scientific output. These results may be of interest to researchers, publishers and professionals interested in this subject, as they provide current information on publications related to this topic.

Portuguese translation and validation of the questionnaires from the Canadian Physical Literacy Assessment-2: a pilot study.

Background/objective: Physical literacy assessment is considered a vital resource to decrease the prevalence of sedentary lifestyles and physical inactivity in children and adolescents worldwide. In Portugal, there is no physical literacy assessment tool for children under 15 years old. The main objective of this study was to carry out a translation and cultural adaptation of the Canadian Physical Literacy Assessment 2 (CAPL-2) into Portuguese, as well as to test its psychometric properties, in children between 8 and 12 years of age. Methods: The questionnaires included in the CAPL-2 were translated using the translation-back-translation method and adapted to their context. The test-retest reliability, internal consistency, and confirmatory factor analysis of the CAPL-2 Portuguese version were analyzed in a sample of 69 and 138 students, respectively, from a school in the Alentejo region (Portugal). Results: The Portuguese version of the CAPL-2 questionnaires demonstrated high internal consistency (Cronbach's α: 0.713-0.979) and test-retest reliability ranging from moderate to nearly perfect in the motivation and confidence domain and knowledge and comprehension domain (ICC = 0.549-0.932). The results showed a good fit after adjusting for covariation paths (CMIN/DF = 1.382, p = 0.105, RMSEA = 0.053, CFI = 0.971, TLI = 0.955, NFI = 0.907). Conclusion: The CAPL-2 version of the questionnaires, translated and adapted to the Portuguese context, demonstrated validity and reliability, making them suitable for assessing physical literacy in children aged 8-12 years.

Effects of a 4-Week After-School Physical Literacy Program on Health-Related Quality of Life and Symptomatology in Schoolchildren with ADHD: A Study Protocol.

Research has shown that physical activity programs led to improvements in children with Attention Deficit Hyperactivity Disorder (ADHD). However, no study evaluating the impact of a physical literacy (PL) program has been conducted. This study aims to examine PL and the effects of an after-school PL program on Health-related quality of life (HRQoL) and ADHD symptomatology including quality and sustained attention. A parallel-group randomised controlled trial will be conducted assessing PL, HRQoL and ADHD symptomatology, both at the beginning and the end of the PL after-school program implementation. The program will last 4 weeks, including two sessions per week lasting 55 min. Sessions will be divided into several parts: greeting (5 min), block I (20 min), block II (20 min) and relaxation and feedback (10 min). Block I will focus on the acquisition of content that contributes to the development of the domains of knowledge and understanding and daily activity; and block II, in addition to favouring physical competence, will seek to improve motivation. If this program proves its effectiveness, it could be an alternative to be included in educational systems, representing a scientific breakthrough regarding physical activity adherence and inactivity-related disease prevention, HRQoL and management of ADHD-associated symptomatology.

Comparison of Glycosylated Haemoglobin, Blood Pressure, and Anthropometric Measurements Depending on Gender and Bodyweight State in Adolescents.

Background/Objective: The greatest anthropometric and physiological changes occur during adolescence. Assessment of growth patterns is necessary to prevent future health risks. Aims: To describe the values of glycosylated haemoglobin (HbA1c), systolic (SBP) and diastolic (DBP) blood pressure, triceps skinfold, and abdominal circumference according to gender and age (between 12 and 17 years), as well as explore the differences between body weight conditions. Methods: A descriptive cross-sectional study was carried out, including 4130 adolescents between 12 and 17 years old. SBP and DBP, HbA1c, triceps skinfold, and abdominal circumference were evaluated. Results: Significant differences were observed between males and females for HbA1c (p < 0.001), SBP (p < 0.001), triceps curl (p < 0.001), and abdominal circumference (p < 0.001), independently of the age group. Regardless of gender and age groups, significant differences were observed between overweight/obese and normal-weight adolescents in SBP (p < 0.001), DBP (p < 0.001 to 0.009), triceps skinfold (p < 0.001), and abdominal perimeter (p < 0.001). Conclusions: Our findings revealed higher SBP, DBP, triceps skinfold, and abdominal circumference in overweight/obese adolescents compared to normal-weight adolescents in both genders.

Associations between Physical Activity Level and Mental Health in the Spanish Population: A Cross-Sectional Study.

Physical inactivity and sedentary lifestyles appear to be critical factors in developing mental health problems, including depression, anxiety, and other diseases in developed societies. This study analysed the associations between physical activity level (PAL) and mental health using the Goldberg General Health Questionnaire (GHQ12) in the Spanish population before the COVID-19 pandemic. A cross-sectional design, based on data from the Spanish National Health Survey (ENSE 2017), the last health survey before the pandemic, was carried out with 17,641 participants. Data did not follow a normal distribution, so non-parametric tests were used to analyse intergroup differences, differences at baseline and post hoc, and correlations between variables. Associations were found between the PAL, mental health and all its dimensions. The groups that performed moderate and intense PAL showed lower values in the GHQ12 questionnaire than those who walked or were inactive. Thus, higher PAL was associated with better mental health indicators, including successful coping, self-esteem and stress. This study provides a framework to compare outcomes between the pre- and post-pandemic periods, as the ENSE is performed every five years.

An Active Retirement Programme, a Randomized Controlled Trial of a Sensorimotor Training Programme for Older Adults: A Study Protocol.

Research shows that exercise training programmes lead to several improvements in older adults' health-related quality of life (HRQoL) and well-being. This study will examine the effects of an active retirement programme on Portuguese older adults, investigating its effects on body composition, physical fitness, HRQoL, and physical activity level (PAL). Therefore, a parallel-group randomised controlled trial will be conducted, including body composition (height and body weight), physical fitness (strength, flexibility, agility, postural control, and gait), HRQoL, and PAL assessments before and after the application of the programme. The programme will be carried out for six months, two days per week (45 min), plus a year of follow-up. The programme will consist of six circuits with eight physical exercises each. The circuits will change at the end of the four weeks (one monthly circuit). The exercises' difficulty will increase throughout the programme, with alternatives for all the participants. If the effectiveness of the programme is demonstrated, implementation in different services and municipalities could be advised, as the actors involved in health and social services should promote the well-being of their citizens through, among others, health-related physical activity and the prevention of diseases associated with inactivity.

Normative Values of Height, Bodyweight and Body Mass Index of 12-17 Years Population from Extremadura (Spain).

Background: Growth charts constitute an essential tool for monitoring adolescents' development. In Extremadura, the percentile growth charts by Faustino Orbegozo Foundation are used. However, they are based on Basque Country population data. Considering socioeconomic differences between Spanish regions, growth chart data could not be appropriate. Aims: to describe the percentile distribution of adolescents from Extremadura and compare these percentiles with those proposed by the Faustino Orbegozo Eizaguirre Foundation that are currently applied in the Extremadura Health Service. Methods: A descriptive cross-sectional study was conducted. A total of 4130 adolescents (12-17 years) participated into the study. Bodyweight and height were assessed. Results: Significant differences were found comparing real measured values with commonly used reference tables for bodyweight at all ages between 12 and 13 years and at 14 years in both gender (p < 0.05). Differences were also found in boys at 15, 16.5 and 17 years (p < 0.05). Regarding height, significant differences were reported at 12, 13, 14.5, 15, 16.5 and 17 years old (p < 0.05) in males; while females' results only revealed differences at 12, 12.5, 14.5 and 15.5 years (p < 0.05). BMI outcomes showed differences in both gender at 12, 12.5, 13, 14 and 15 years old (p < 0.05). Differences were also found at 16 and 14.5 years for boys and girls, respectively (p < 0.05). Conclusion: Bodyweight, height and BMI of adolescents from Extremadura differ of the reference values currently applied. Hence, this study's outcomes suggest the need to use new indicators, adapted to the physical and anthropometric reality of children and young people to avoid the possible normalisation of situations of thinness, overweight or obesity.

Descriptive Study about Bodyweight Status of Extremadura Adolescents. Are We Applying the Best Indicator as the Reference Parameter?

Background: There is no agreed criteria that establishes childhood obesity thresholds based on BMI, which may be used to assess adolescent overweight/obesity. This tool has been determined at the most practical and least costly in classifying bodyweight status in adolescents. However, it is an indicator of bodyweight and not adiposity. Aims: To assess bodyweight status of Extremadura adolescents by sex and age using international, national, and regional reference criteria and comparing the different diagnoses criteria. Methods: A descriptive cross-sectional study was conducted with 4130 adolescents (12-17 years). Bodyweight and height were assessed. Results: Pairwise comparisons indicates that the World Health Organization (WHO) classified 542 individuals in a different category compared to Faustino Obergozo (FO), and 1028 individuals with respect to the Extremadura adolescents' percentiles (EX). Moreover, FO classified 684 adolescents in a different category than EX. Despite the concordance in diagnostic criteria (by Cohen's kappa test) reported between the WHO, FO, and EX for all bodyweight categories in both sexes and all age ranges, significant differences were found (assessed by Cochran Q test and McNemar test as post-hoc) between the WHO and FO for all bodyweight proportion except in the thinness category in girls (15-17 years) and boys (12-14 years). Meaningful differences were also obtained comparing WHO and EX for each bodyweight category in all ages and sexes. Comparisons between FO and EX revealed significant differences for all bodyweight categories in all participants except for overweight in girls (12-14 years) and boys (15-17 years) and normal weight and obesity in girls (15-17 years). Conclusions: the WHO, FO, and EX criteria present different outcomes estimating overweight and/or obesity prevalence in adolescents aged between 12 and 17 years. The change from Extremadura criteria to the WHO reference will result in more adolescents being diagnosed as overweight or obese.
