Criterion-related validity of the short form of the international physical activity questionnaire in adults who are Deaf

Background: To implement appropriate programs for promoting physical activity (PA) in people who are Deaf, it is important to have valid instruments for assessing PA in this population. Objective: The main purpose of this study was to examine the criterion validity of the short form of the International Physical Activity Questionnaire (IPAQ-S) in Deaf adults. Method: This study included 44 adults (18e65 years) of both genders (63.6% were females) who met the inclusion criteria. Objective measures of PAwere collected using accelerometers, which were worn by each participant during one week. After using the accelerometer, the IPAQ-S was applied to assess participants’ physical activity during the last 7 days. Results: There was no significant correlation between the average time spent in moderate to vigorous physical activity (MVPA) as measured by the accelerometer (40.1 6 24.5 min/day) and by the IPAQ-S (41.3 6 57.5 min/day). The IPAQ-S significantly underestimated the time spent in sedentary behavior (7.6 6 2.7 h/day vs. 10.1 6 1.6 h/day). Sedentary behavior and MVPA as measured by the accelerometer and the IPAQ-S showed limited agreement. Conclusions: Our results show some limitations on the use of IPAQ-S for quantifying PA among adults who are Deaf. The IPAQ-S tends to overestimate the MVPA and to underestimate sedentary behavior in adults who are Deaf.

Increased physical activity and fitness above the 50th percentile prevents the institutionalization of elderly people: a cross-sectional pilot study.

Introduction Institutionalization in a nursing home restricts autonomy, most notably free will, free choice, and free action. Decreased physical activity and fitness are predictive of disability and dependence (Rikli & Jones, 2013; Tak, Kuiper, Chorus, & Hopman-Rock, 2014); however little is known about the impact of these factors on institutionalization. Thus, this study aimed to analyze the impact of physical activity and fitness and on the risk of elderly people without cognitive impairment become institutionalized. Methods This cross-sectional study involved 195 non-institutionalized (80.14.4yrs) and 186 institutionalized (83.85.2yrs) participants. Cognitive impairment was assessed using Mini-Mental State Examination, physical activity was assessed using the International Physical Activity Questionnaire, and measures of physical fitness were determined by the Senior Fitness Test. Results: Multivariate binary logistic analysis selected 4 main predictors of institutionalization in both genders. The likelihood of becoming institutionalized increased by +18.6% for each additional year of age, while it decreased by -24.8% by each fewer kg/m2 in BMI, by -0.9% for each additional meter performed in the aerobic endurance test and by -2.0% for each additional 100MET-min/wk of physical activity expenditure (p<0.05). Values ≤50th percentile (age ≥81yrs, BMI≥26.7kg/m2, aerobic endurance ≤367.6m, and physical activity ≤693MET-min/wk) were computed using Receiver Operating Characteristics analysis as cut-offs discriminating institutionalized from non-institutionalized elderly people. Conclusion The performance of physical activity, allied to an improvement in physical fitness (mainly BMI and aerobic endurance) may prevent the institutionalization of elderly people without cognitive impairment only if they are above the 50th percentile; the following is highly recommend: expending ≥693MET-min/wk on physical activity, being ≤26.7kg/m2 on BMI, and being able to walk ≥367.6m in the aerobic endurance test, especially above the age of 80 years. The discovery of this trigger justifies the development of physical activity programs targeting the pointed cut-offs in old, and very old people. References Rikli, R., & Jones, C. (2013).

Actividade física e autonomia instrumental das pessoas idosas

Pretende-se perceber se existe uma relação entre o nível regular de actividade física praticado pelas pessoas idosas e a sua autonomia instrumental. Desenvolveu-se um estudo descritivo, correlacional e transversal, no ano 2010, com amostra intencional constituída por 100 indivíduos com idade igual ou superior a 60 anos, de ambos sexos. A colheita de dados foi efectuada em dois ginásios e dois centros de dia localizados na cidade de Lisboa, e foram utilizados como instrumentos a Escala de Actividades Instrumentais de Vida Diária de Lawton e Brody e o International Physical Activity Questionnaire. Obteve-se uma média de idades de 76 anos, sendo 78% dos inquiridos do sexo feminino. Inseriram-se 30% na categoria de actividade física “ligeira”, 45% na “moderada” e 25% na “vigorosa”. Relativamente à autonomia instrumental, a maioria era moderadamente dependente. Verificou-se que o grau de autonomia instrumental dos idosos aumenta com o incremento da actividade física praticada (ρS=0.815; p-value<0.001); Abstract: This work seeks to realize if there is a relationship between the level of regular physical activity practiced by elderly persons and its instrumental autonomy. A descriptive, related and transversal study was developed in the year 2010, with an intentional sample consisting of 100 individuals, aged 60 years or above, of both genders. The data collection was carried out in two gymnasiums and two day care centers located in the city of Lisbon, and were used the Lawton and Brody’s Instrumental Activities of Daily Living Scale and the International Physical Activity Questionnaire. A mean age of 76 years was obtained and 78% of the respondents were female. 30% were classified as having a "low" physical activity level, 45% as "moderate" and 25% as "high". Regarding instrumental autonomy, most were moderately dependent. It was verified that the degree of instrumental autonomy of the elderly increases with increased physical activity (ρS=0.815; p-value<0.001).

Does an In-Season Detraining Period Affect the Shoulder Rotator Cuff Strength and Balance of Young Swimmers?

Aims: To compare the physical activity, sedentary activity and health-related quality of life (HRQoL) in institutionalized vs. non-institutionalized elderly, and to establish a pattern of relationship and prediction of physical and sedentary activity with physical and mental components of HRQoL. Methods: The sample consisted of 383 elderly with ≥ 75 years old (n=187 institutionalized and n=196 non-institutionalized). Were administered the International Physical Activity Questionnaire (IPAQ) and Short Form 36 Health Survey (SF-36) for evaluated the physical and sedentary activity and HRQoL. Also was used the Mini Mental State Examination (MMSE) as exclusion criteria for cognitive problems in the elderly. Results: Differences between institutionalized and non-institutionalized elderly were found in moderate-intensity activities and walking, a favour of non-institutionalized. The institutionalized elderly remain more minutes in sedentary activity. Also, were observed differences between both groups in physical component of HRQoL, a favour of non-institutionalized elderly. The mental component remained unchanged. The multivariate regression analyses showed that physical activity predicted the physical (8 to 12%) and mental (5 to 8%) components of HRQoL for institutionalized and non-institutionalized elderly. Conclusions: Non-institutionalized elderly were more physically active, spent less time in sedentary activity and showed better perception physical component of HRQoL that institutionalized elderly. An important and encouraging result of this study was that physical activity is a predictor of improved physical and mental component of HRQoL for institutionalized and non-institutionalized elderly.
