          Abstract

          ABSTRACT The purpose was to investigate the use of physical activity trackers (PAT) and to analyze the relationship between its use and physical activity (PA) levels. Participants were N=1498 (N=841 females) aged 14-85 years. Interest, use and preferences for PAT were measured by questionnaire. PA was measured using IPAQ short version. Kruskal-Wallis Test was used to test the differences in PA levels between participants. Out of all the participants who practice PA/exercise regularly, 59% do not use PAT, 27% were using, and 14% have used. Adolescents, middle-aged females and older males, who use PAT did significantly more vigorous PA than participants who not use. Young adults who use PAT did significantly more moderate and vigorous PA than participants who not use. And middle-aged males who use PAT did significantly more total week PA, vigorous PA and walking PA than participants who not use. About half of the participants that exercise regularly use PAT. Despite participants that use PAT tend to have higher levels of habitual PA, it is not conclusive that the use of PAT leads to do more PA.

          RESUMO (1500 palavras) (mesma ordem como títulos) O objetivo deste estudo foi avaliar o uso de dispositivos de avaliação da atividade física (PAT) e analisar a relação entre o seu uso e os níveis de atividade física (AF). Os participantes foram N = 1498 (N = 841 mulheres) com idades compreendidas entre 14 e 85 anos. O interesse, uso e preferências pelo PAT foram medidos por questionário. A AF foi avaliada usando a versão curta do IPAQ. O teste de Kruskal-Wallis foi utilizado para testar as diferenças nos níveis de AF entre os participantes. De todos os participantes que praticam AF / exercitam-se regularmente, 59% não usam PAT, 27% estavam a usar e 14% já usaram. Adolescentes, mulheres de meia idade e homens mais velhos, que usam o PAT, fizeram AF significativamente mais vigorosa do que os participantes que não usam. Jovens adultos que usam PAT fizeram AF significativamente mais AF moderada a vigorosa do que os participantes que não usam. E os homens de meia-idade que usam PAT fizeram significativamente mais AF total na semana, AF vigorosa e AF de caminhada que os participantes que não usam. Cerca de metade dos participantes que se exercitam regularmente usam o PAT. Apesar dos participantes que usam o PAT tenderem a ter níveis mais altos de AF habitual, não é conclusivo que o uso do PAT indica mais AF.

          RESUMEN El propósito fue investigar el uso de rastreadores de actividad física (RAF) y analizar la relación entre su uso y los niveles de actividad física (AF). Los participantes fueron N = 1498 (N = 841 mujeres) de 14 a 85 años. El interés, el uso y las preferencias de RAF se midieron mediante un cuestionario. La AF se midió utilizando la versión corta de IPAQ. La prueba de Kruskal-Wallis se utilizó para evaluar las diferencias en los niveles de AF entre los participantes. De todos los participantes que practican AF regularmente, el 59% no usa RAF, el 27% lo estaba usando y el 14% lo ha usado. Los adolescentes, las mujeres de mediana edad y los hombres mayores, que usan RAF, hicieron significativamente más AF intensa que los participantes que no lo usan. Los adultos jóvenes que usan RAF tuvieron niveles de AF moderada y vigorosa significativamente más elevada que los participantes que no lo usan. Los hombres de mediana edad que usan RAF tuvieron significativamente más AF global y AF vigorosa y caminaban más que los participantes que no lo usan. Alrededor de la mitad de los participantes que hacen ejercicio regularmente usan RAF. A pesar de que los participantes que usan RAF tienden a tener niveles más altos de AF, no es concluyente que el uso de RAF conduzca a más PA.

          International physical activity questionnaire: 12-country reliability and validity.

          Physical inactivity is a global concern, but diverse physical activity measures in use prevent international comparisons. The International Physical Activity Questionnaire (IPAQ) was developed as an instrument for cross-national monitoring of physical activity and inactivity. Between 1997 and 1998, an International Consensus Group developed four long and four short forms of the IPAQ instruments (administered by telephone interview or self-administration, with two alternate reference periods, either the "last 7 d" or a "usual week" of recalled physical activity). During 2000, 14 centers from 12 countries collected reliability and/or validity data on at least two of the eight IPAQ instruments. Test-retest repeatability was assessed within the same week. Concurrent (inter-method) validity was assessed at the same administration, and criterion IPAQ validity was assessed against the CSA (now MTI) accelerometer. Spearman's correlation coefficients are reported, based on the total reported physical activity. Overall, the IPAQ questionnaires produced repeatable data (Spearman's rho clustered around 0.8), with comparable data from short and long forms. Criterion validity had a median rho of about 0.30, which was comparable to most other self-report validation studies. The "usual week" and "last 7 d" reference periods performed similarly, and the reliability of telephone administration was similar to the self-administered mode. The IPAQ instruments have acceptable measurement properties, at least as good as other established self-reports. Considering the diverse samples in this study, IPAQ has reasonable measurement properties for monitoring population levels of physical activity among 18- to 65-yr-old adults in diverse settings. The short IPAQ form "last 7 d recall" is recommended for national monitoring and the long form for research requiring more detailed assessment.

            Global trends in insufficient physical activity among adolescents: a pooled analysis of 298 population-based surveys with 1·6 million participants

            Summary Background Physical activity has many health benefits for young people. In 2018, WHO launched More Active People for a Healthier World, a new global action on physical activity, including new targets of a 15% relative reduction of global prevalence of insufficient physical activity by 2030 among adolescents and adults. We describe current prevalence and trends of insufficient physical activity among school-going adolescents aged 11–17 years by country, region, and globally. Methods We did a pooled analysis of cross-sectional survey data that were collected through random sampling with a sample size of at least 100 individuals, were representative of a national or defined subnational population, and reported prevalence of of insufficient physical activity by sex in adolescents. Prevalence had to be reported for at least three of the years of age within the 10–19-year age range. We estimated the prevalence of insufficient physical activity in school-going adolescents aged 11–17 years (combined and by sex) for individual countries, for four World Bank income groups, nine regions, and globally for the years 2001–16. To derive a standard definition of insufficient physical activity and to adjust for urban-only survey coverage, we used regression models. We estimated time trends using multilevel mixed-effects modelling. Findings We used data from 298 school-based surveys from 146 countries, territories, and areas including 1·6 million students aged 11–17 years. Globally, in 2016, 81·0% (95% uncertainty interval 77·8–87·7) of students aged 11–17 years were insufficiently physically active (77·6% [76·1–80·4] of boys and 84·7% [83·0–88·2] of girls). Although prevalence of insufficient physical activity significantly decreased between 2001 and 2016 for boys (from 80·1% [78·3–81·6] in 2001), there was no significant change for girls (from 85·1% [83·1–88·0] in 2001). There was no clear pattern according to country income group: insufficient activity prevalence in 2016 was 84·9% (82·6–88·2) in low-income countries, 79·3% (77·2–87·5) in lower–middle-income countries, 83·9% (79·5–89·2) in upper–middle-income countries, and 79·4% (74·0–86·2) in high-income countries. The region with the highest prevalence of insufficient activity in 2016 was high-income Asia Pacific for both boys (89·0%, 62·8–92·2) and girls (95·6%, 73·7–97·9). The regions with the lowest prevalence were high-income western countries for boys (72·1%, 71·1–73·6), and south Asia for girls (77·5%, 72·8–89·3). In 2016, 27 countries had a prevalence of insufficient activity of 90% or more for girls, whereas this was the case for two countries for boys. Interpretation The majority of adolescents do not meet current physical activity guidelines. Urgent scaling up of implementation of known effective policies and programmes is needed to increase activity in adolescents. Investment and leadership at all levels to intervene on the multiple causes and inequities that might perpetuate the low participation in physical activity and sex differences, as well as engagement of youth themselves, will be vital to strengthen the opportunities for physical activity in all communities. Such action will improve the health of this and future young generations and support achieving the 2030 Sustainable Development Goals. Funding WHO.

              Systematic review of the health benefits of physical activity and fitness in school-aged children and youth

              Background The purpose was to: 1) perform a systematic review of studies examining the relation between physical activity, fitness, and health in school-aged children and youth, and 2) make recommendations based on the findings. Methods The systematic review was limited to 7 health indicators: high blood cholesterol, high blood pressure, the metabolic syndrome, obesity, low bone density, depression, and injuries. Literature searches were conducted using predefined keywords in 6 key databases. A total of 11,088 potential papers were identified. The abstracts and full-text articles of potentially relevant papers were screened to determine eligibility. Data was abstracted for 113 outcomes from the 86 eligible papers. The evidence was graded for each health outcome using established criteria based on the quantity and quality of studies and strength of effect. The volume, intensity, and type of physical activity were considered. Results Physical activity was associated with numerous health benefits. The dose-response relations observed in observational studies indicate that the more physical activity, the greater the health benefit. Results from experimental studies indicate that even modest amounts of physical activity can have health benefits in high-risk youngsters (e.g., obese). To achieve substantive health benefits, the physical activity should be of at least a moderate intensity. Vigorous intensity activities may provide even greater benefit. Aerobic-based activities had the greatest health benefit, other than for bone health, in which case high-impact weight bearing activities were required. Conclusion The following recommendations were made: 1) Children and youth 5-17 years of age should accumulate an average of at least 60 minutes per day and up to several hours of at least moderate intensity physical activity. Some of the health benefits can be achieved through an average of 30 minutes per day. [Level 2, Grade A]. 2) More vigorous intensity activities should be incorporated or added when possible, including activities that strengthen muscle and bone [Level 3, Grade B]. 3) Aerobic activities should make up the majority of the physical activity. Muscle and bone strengthening activities should be incorporated on at least 3 days of the week [Level 2, Grade A].
