The aim of the current study was to compare bone loading due to physical activity between lean, and overweight and obese individuals. Fifteen participants (lower BMI group: BMI < 25 kg/m2, n = 7; higher BMI group: 25 kg/m2 < BMI < 36.35 kg/m2, n = 8) wore a tri-axial accelerometer on 1 day to collect data for the calculation of bone loading. The International Physical Activity Questionnaire (short form) was used to measure time spent at different physical activity levels. Daily step counts were measured using a pedometer. Differences between groups were compared using independent t-tests. Accelerometer data revealed greater loading dose at the hip in lower BMI participants at a frequency band of 0.1–2 Hz (P = .039, Cohen’s d = 1.27) and 2–4 Hz (P = .044, d = 1.24). Lower BMI participants also had a significantly greater step count (P = .023, d = 1.55). This corroborated with loading intensity (d ≥ 0.93) and questionnaire (d = 0.79) effect sizes to indicate higher BMI participants tended to spend more time in very light activity, and less time in light and moderate activity. Overall, participants with a lower BMI exhibited greater bone loading due to physical activity; participants with a higher BMI may benefit from more light and moderate level activity to maintain bone health.

Objective: To investigate the effect of item order on physical activity (PA) estimates using the International Physical Activity Questionnaire – short form (last 7 day) telephone interview (IPAQ-S7T). Method: The IPAQ-S7T was conducted for Time 1 (Hawai`i) and sample 1 (Belgium). Then item order was reversed for Times 2, 3 (Hawai`i), and sample 2 (Belgium). Results: In Hawai`i, vigorous activity levels were higher, walking levels lower for Time 1, compared to Times 2 and 3. Moderate activity was higher at Time 1 than Time 3. The Belgium study reported higher levels of vigorous activity for sample 1, compared to sample 2. Total volume of PA across time points was unchanged for the Hawai`i study, but decreased with reversed items in the Belgium study. Conclusion: Item ordering affects the levels and duration of reported PA using the IPAQ-S7T. This warrants further research on order efficacy and whether other PA measures are affected.

The goal of this study is to investigate whether or not the attention level of middle school students’ changes depends on their physical activity. Fourty middle-school students who have been taking education in Yalova province joined the study as a volunteer. Fifty percent of the participants are male and the others are female. The experimental and the control groups have been formed and each of these groups consisted of 10 male and 10 female students. International physical activity questionnaire short form and Burdon concentration test were used as the information gathering instruments. To compare the experimental groups with the control groups, a T-test was used for independent groups. To compare one to another participant in each group, also T-test was used for dependent groups. Using the international physical activity questionnaire short form, preliminary and final tests were applied to each participant. According to the results of the questionnaire, weekly MET values of each participant were calculated. At the beginning of the study, the Burdon concentration test applied to each participant. Our study has finished in eight weeks. The physical activity levels of the control group were kept constant and no information was given. Twenty pieces of Xiaomi-mi-band-3 smart bracelets were supplied to the experimental group and they were informed about the features of these devices. At the end of 8 weeks period, the international physical activity questionnaire short form and Burdon concentration test were applied to each participant again. According to the physical activity levels of the control group, no significant difference has been found between the results of the Burdon concentration test (p > 0.05). But according to the physical activity levels of the experimental group, a significant difference has been found between the results of the Burdon concentration test (p < 0.05). As a result, it has been observed that an increase in levels of physical activity provides an increase in concentration. In conclusion, it is seen that many students and young people have low levels of physical activity due to both lifestyle and virtual world dependence. Although there are many factors, the decrease in physical activity causes low levels of attention. The better the attention levels of our students and young people, the more successful they will be in their lives. Our study and most of the mentioned studies reveal that attention is a developable skill and a situational factor that is open to influence. Therefore, attention development in children who are directed to recreational activities should be emphasized, especially during periods of rapid physical growth. If we want our students and young people to be more successful, they should be encouraged and supported more about physical activity.

Abstract Background To tailor physical activity treatment programs for patients with osteoarthritis, clinicians need valid and feasible measurement tools to evaluate habitual physical activity. The widely used International Physical Activity Questionnaire-Short Form (IPAQ-SF) is not previously validated in patients with osteoarthritis. Purpose To assess the concurrent criterion validity of the IPAQ-SF in patients with osteoarthritis, using an accelerometer as a criterion-method. Method Patients with osteoarthritis (n = 115) were recruited at The Division of Rheumatology and Research at Diakonhjemmet Hospital (Oslo, Norway). Physical activity was measured by patients wearing an accelerometer (ActiGraph wGT3X-BT) for seven consecutive days, followed by reporting their physical activity for the past 7 days using the IPAQ-SF. Comparison of proportions that fulfilled physical activity recommendations as measured by the two methods were tested by Pearson Chi-Square analysis. Differences in physical activity levels between the IPAQ-SF and the accelerometer were analyzed with Wilcoxon Signed-Rank Test and Spearman rank correlation test. Bland-Altman plots were used to visualize the concurrent criterion validity for total- and intensity-specific physical activity levels. Results In total, 93 patients provided complete physical activity data, mean (SD) age was 65 (8.7) years, 87% were women. According to the IPAQ-SF, 57% of the patients fulfilled the minimum physical activity recommendations compared to 31% according to the accelerometer (p = 0.043). When comparing the IPAQ-SF to the accelerometer we found significant under-reporting of total physical activity MET-minutes (p = < 0.001), sitting (p = < 0.001) and walking (p < 0.001), and significant over-reporting of moderate-to-vigorous physical activity (p < 0.001). For the different physical activity levels, correlations between the IPAQ-SF and the accelerometer ranged from rho 0.106 to 0.462. The Bland-Altman plots indicated an increased divergence between the two methods with increasing time spent on moderate-to-vigorous intensity physical activity. Conclusion Physical activity is a core treatment of osteoarthritis. Our finding that patients tend to over-report activity of higher intensity and under-report low-intensity activity and sitting-time is of clinical importance. We conclude that the concurrent criterion validity of the IPAQ-SF was weak in patients with osteoarthritis.

Objective. The study examines relationships between physical activity levels and income status of working-age city residents. Methods. The study was carried out in the years 2014 and 2015 in Wrocław, Poland. The study sample comprised 4332 participants (2276 women; 2056 men) aged 18 to 64 years. Respondents’ habitual physical activity levels were measured with the International Physical Activity Questionnaire Short Form (IPAQ-SF), while their income status was assessed with author’s own Socio-Economic Status of Working-Age People Questionnaire (S-ESQ). Results. The results revealed positive correlations between the level of physical activity and income status of male and female working-age residents of Wrocław. The highest physical activity levels were noted among respondents with a steady income, as well as among respondents with the highest income and savings and with no debts. The odds for respondents’ above average physical activity levels were the greatest in women with the highest income and with savings and in debt-free men and women. Conclusion. Effective actions should be developed aimed at improvement of physical activity levels of people in an adverse financial situation.

Abstract Background The objective was to compare levels of physical activity (PA) in a large sample of Spanish people with diabetes with and without cataracts. To our knowledge, this is the first study comparing PA levels in people with diabetes with and without cataracts in a large representative sample. Methods Cross-sectional data from the Spanish National Health Survey 2017 were analyzed (n = 1014 people with diabetes; 43.1% females; age range 15–69 years; mean age 58.4 ± 9.2 years). International Physical Activity Questionnaire (IPAQ) short form was used to measure PA. Total MET-min week−1 of PA were calculated and participants were divided into two categories according to American Diabetes Association PA guidelines: (i) &lt;600 MET-min week−1. (ii) At least 600 MET-min week−1. Diabetes and cataracts were self-reported in response to the questions ‘Have you ever been diagnosed with diabetes/cataracts?’ Participants also reported other variables including age, gender, marital status, living as a couple, education, smoking, alcohol consumption and obesity. Statistical analysis was performed with SPSS 23.0. Results The overall prevalence of cataract was 14.0% and the overall prevalence of people doing &lt;600 MET-min week−1 of PA was 35.4%. The prevalence of cataract was significantly lower in those doing more PA (12.1% vs. 17.5%; P = 0.016). Those without cataracts were significantly more active than those with cataracts (1846.8 vs. 1289.4 MET-min week−1; P = 0.001). The adherence to American Diabetes Association PA guidelines was significantly higher in those without cataracts (66.1% vs. 55.6%; P = 0.016). Conclusions Interventions to promote PA targeting people with both diabetes and cataracts are warranted.

Background:The International Physical Activity Questionnaire-Short Form (IPAQ-S) has been evaluated against accelerometer-determined physical activity measures in small homogenous samples of adults in the United States. There is limited information about the validity of the IPAQ-S in diverse US samples.Methods:142 Blacks residing in low-income housing completed the IPAQ-S and wore an accelerometer for up to 6 days. Both 1- and 10-minute accelerometer bouts were used to define time spent in light, moderate, and vigorous physical activity.Results:We found fair agreement between the IPAQ-S and accelerometer-determined physical activity (r = .26 for 10-minute bout, r = .36 for 1-minute bout). Correlations were higher among men than women. When we classified participants as meeting physical activity recommendations, agreement was low (kappa = .04, 10-minute; kappa = .21, 1-minute); only 25% of individuals were classified the same by both instruments (10-minute bout).Conclusions:In one of the few studies to assess the validity of a self-reported physical activity measure among Blacks, we found moderate correlations with accelerometer data, though correlations were weaker for women. Correlations were smaller when IPAQ-S data were compared using a 10- versus a 1-minute bout definition. There was limited evidence for agreement between the instruments when classifying participants as meeting physical activity recommendations.

El principal objetivo fue determinar si existen diferencias en los niveles de actividad física (NAF) y la intención de ser físicamente activo entre países en función del género, curso y estatus socioeconómico. Participaron 3052 adolescentes (14.58 ± 1.39 años), 1516 chicos y 1536 chicas. Del total, 734 chilenos y 2318 españoles. Las variables medidas fueron los NAF con el “International Physical Activity Questionnaire- Short Form” (IPAQ-SF), la intención de ser físicamente activo con el “Intention to be Physically Active” y el estatus socioeconómico familiar con el “Family Affluence Scale II” (FASII). Se encontraron diferencias significativas en los NAF y en la intención de ser físicamente activo entre países en función del género (p < .001), curso (p < .001) y estatus socioeconómico (p < .01), siendo más altas en España. Además, la relación de cada una de estas variables con los NAF y la intencionalidad varía según el país. Como la relación de las variables sociodemográficas con los NAF y la intención de ser físicamente activo varía en función del país sería necesario llevar a cabo más estudios transculturales que permitan realizar intervenciones de promoción de actividad física y salud adaptadas a las necesidades de cada lugar. === The main goal was to analyze the physical activity levels and the intention to be physically active differences between both countries regarding the gender, course and socioeconomic status. The sample was 3,052 adolescents (14.58 ± 1.39 years), 1,516 males and 1,536 females. From the whole participants, 734 were Chilean and 2,318 Spanish. Physical activity levels were measured using the “International Physical Activity Questionnaire- Short Form” (IPAQ-SF), the intention to be physically active using the “Intention to be Physically Active” scale and the socioeconomic status using the “Family Affluence Scale II” (FASII). There are significant differences in physical activity levels and the intention to be physically active between both countries according to the gender (p < .001), course (p < .001) and socioeconomic status (p < .01). Data were higher in Spain than Chile. Moreover, the relation between these sociodemographic variables with physical activity levels and the intention to be physically active were different regarding the country. As the relation between these sociodemographic variables with physical activity levels and the intention to be physically active is different according to the country, cross-cultural researches are required to develop physical activity and health interventions adapted to people`s needs.

The lockdown with a prohibition of free mobility introduced in many countries has affected restrictions in physical activity (PA). The purpose of the study was to compare PA during restrictions and the “unfreezing” stage. The study group consisted of 89 healthy adult students. To assess the level of PA, a long version of the International Physical Activity Questionnaire (IPAQ) was used. The first evaluation was carried out in the period from 16 to 20 April 2020 at the time of the lockdown and the second in the period from 11 to 14 May 2020 during the so-called “unfreezing”. The average total PA rate during the first measurement was 8640 metabolic equivalent (MET)-min/week and in the second, 10,560 MET-min/week. The analysis of total energy expenditure showed a statistically significant difference (p < 0.029). The establishment of “unfreezing” laws for sport and recreation and the reduction of restrictions have significantly contributed to an increase in the overall level of PA. Based on our outcomes, we recommend students follow the scientific guidelines for undertaking PA (i.e., WHO) during the pandemic in order to maintain an appropriate pro-healthy dose of exercise.

Interventions to increase physical activity in children have adopted broad approaches and achieved varying success. There is a need to adopt approaches underpinned with a theoretical basis. Accordingly, the aim here was to implement and evaluate a 12-week intervention designed using the concepts of the COM-B model to determine the effect this has on physical activity levels. One hundred and forty-seven school-age children (mean age 8.9 ± 1.3 years) took part in a 12-week program delivered in a school setting. Topics included physical activity, healthy eating, sleep quality and reducing screen time/sedentary activities when not in school. A sample of participants wore a wrist-worn accelerometer for seven days pre-and post-intervention (N = 11). The physical activity frequency was unchanged (2.9 ± 1.0 AU) when compared with post-intervention values (3.1 ± 0.8 AU, mean increase 6.8 ± 3.7%, p > 0.05). Changes were observed in the daily consumption of fruit and vegetables (pre-intervention 44.6% vs. post-intervention 60.2%, p < 0.05). Sedentary time, light activity, moderate activity and vigorous activity were unchanged post-intervention (p > 0.05). There is a need to adopt a broader approach that incorporates a theoretical basis and considers the complex ways by which physical activity behaviours are influenced.

Abstract Background Physical inactivity is a global phenomenon in European welfare countries. Proper monitoring is essential to measure the physical activity level of the population. Methods In the Hungarian cohort of the European Physical Activity and Sport Monitoring System (EUPASMOS) project, our participants (N = 598) completed sociodemographic questions and the International Physical Activity Questionnaire – short form (IPAQ-SF) survey. The validity and reliability of the subjective measurement tool were examined, IPAQ-SF outcomes were contrasted against triaxial RM42 accelerometer wore for 7 consecutive days. Results The IPAQ-SF showed moderate internal consistency (Cronbach Alpha = 0.647). The concurrent validity of the IPAQ-SF to triaxial accelerometer indicated a significant weak-to-moderate correlation (R = 0.111–0.338, p = 0.042; p < 0.001). The test-retest reliability showed a significant correlation between two measurements (R = 0.788–0.981, p < 0.001). Conclusion The Hungarian version of the IPAQ-SF had excellent test-retest reliability, but low-to-fair concurrent validity for moderate and vigorous physical activity, walking and sitting time, as compared to the objective criterion measure among Hungarian adults.
