Differences on Habitual Physical Activity Index in Primary Schoolchildren according to Age and Gender

The World Health Organization (WHO) has warned that a large majority of children do not reach its recommendations on physical activity for health, i.e., 60 min a day of moderate to vigorous physical activity. The objective of this study was to know the index of habitual physical activity in different contexts where the child interacts: school index (SCHOOL-I), extracurricular/sports activity index (SPORT-I), free time index (LEISURE-I) and the total habitual physical activity index (GLOBAL-I) based on age and gender. 900 Primary Education schoolchildren from Galicia (Spain) aged 10–12 years (M = 10.84; SD = 0.67) participated, of which 454 (50.40%) were boys and 446 (49.6%) girls. For data collection, the validated Inventory of Habitual Physical Activity in Schoolchildren (IAFHE) questionnaire was used. The results show a significant main effect on the age factor in SCHOOL-I (p < 0.001), and in GLOBAL-I (p = 0.034), the rates being higher in 10-year-old children compared to 11 and 12. A significant main effect has also been found in the gender factor in SCHOOL-I (p < 0.001), SPORT-I (p < 0.001) and in GLOBAL-I (p < 0.001), being greater in boys than in girls. It is concluded that, as school age increases, a lower index of physical activity is registered, this being higher in boys compared to girls. It is necessary to establish strategies to promote the practice of physical activity from different agents and in different contexts.

Influence of the Perception of Barriers in Practice of PA in Adolescents: Explanatory Model

Background: Sedentarism is an important risk factor for non-communicable diseases. To avoid it, it is necessary to establish the barriers which influence a low level of practice of Physical Activity. Methods: This study, conducted with 833 students, aims to describe a model to explain the barriers determining the level of practice of Physical Activity in adolescents according to age, school year, BMI and gender. The inclusion of the analyzed barriers followed the tetra-factorial model: Body image/physical and social anxiety; Tiredness/laziness; Responsibilities/lack of time and Environment/facilities. Results: The barriers to Physical Activity in adolescents are fatigue and sloth, and temporary obligations. The barrier that least influences the practice of Physical Activity is the environment and body image. It is determined that the subjects with the lowest Physical Activity index were those with a high fatigue and laziness score and higher age. The level of physical activity of this population is medium (95% CI, 2.8274–2.9418). Conclusions: It is necessary to overcome tiredness or apathy towards the practice of Physical Activity, especially in those under 16 years of age.

Is Sitting Always Inactive and Standing Always Active? A Simultaneous Free-Living activPal and ActiGraph Analysis

Sedentary Behavior (SB), defined as sitting with minimal physical activity, is an emergent public health topic. However, the measurement of SB considers either posture (e.g., activPal) or physical activity (e.g., ActiGraph), and thus neglects either active sitting or inactive standing. The aim of this study was to determine the true amount of active sitting and inactive standing in daily life, and to analyze by how much these behaviors falsify the single sensors’ sedentary estimates. Sedentary time of 100 office workers estimated with activPal and ActiGraph was therefore compared with Bland-Altman statistics to a combined sensor analysis, the posture and physical activity index (POPAI). POPAI classified each activPal sitting and standing event into inactive or active using the ActiGraph counts. Participants spent 45.0% [32.2%–59.1%] of the waking hours inactive sitting (equal to SB), 13.7% [7.8%–21.6%] active sitting, and 12.0% [5.7%–24.1%] inactive standing (mean [5th–95th percentile]). The activPal overestimated sedentary time by 30.3% [12.3%–48.4%] and the ActiGraph by 22.5% [3.2%–41.8%] (bias [95% limit-of-agreement]). The results showed that sitting is not always inactive, and standing is not always active. Caution should therefore be paid when interpreting the activPal (ignoring active sitting) and ActiGraph (ignoring inactive standing) measured time as SB.

Sleep disturbance as a moderator of the association between physical activity and later pain onset among American adults aged 50 and over: evidence from the Health and Retirement Study

ObjectiveTo examine whether sleep disturbance modifies the association between physical activity and incident pain.DesignProspective population-based study.SettingHealth and Retirement Study.ParticipantsAmerican adults aged ≥50 years who reported no troublesome pain in 2014 were re-assessed for pain in 2016. Of 9828 eligible baseline respondents, 8036 (82%) had complete follow-up data for adjusted analyses (weighted analysis population N=42 407 222).ExposuresPhysical activity was assessed via interview with questions about time spent in moderate and vigorous physical activity. Sleep disturbance, assessed using a modified form of the Jenkins Sleep Scale, was examined as a potential moderator.Main outcome measureTroublesome pain.ResultsIn weighted analyses, 37.9% of the 2014 baseline pain-free sample participated in moderate or vigorous physical activity once a week or less, with an overall mean Physical Activity Index Score of 9.0 (SE=0.12). 18.6% went on to report troublesome pain in 2016. Each one-point higher on the Physical Activity Index Score was associated with a reduced odds ratio (OR) of incident pain for those who endorsed sleep disturbance never/rarely (OR=0.97, 95% CI 0.94 to 0.99), but not for those who endorsed sleep disturbance sometimes (OR=0.99, 95% CI 0.97 to 1.01) or most of the time (OR=1.01, 95% CI 0.99 to 1.03). The analysis of possible interaction demonstrated that frequency of sleep disturbance moderated the physical activity and incident pain association (Wald test: p=0.02).ConclusionsThe beneficial association of physical activity on reduced likelihood of later pain was only observed in persons who endorsed low levels of sleep disturbance.

Tracking da atividade física em adolescentes entre 2010 e 2014

Even though the benefits of regular physical activity (PA) are well established, national tracking studies are still scarce. The aim of the study was to analyze the tracking of physical activity (PA) in 2010, 2012 and 2014 of adolescents from Jacarezinho, Paraná. Adolescents (ages: 15.6 ± 0.6 years) were evaluated in 2014, who had participated in the 2010 and 2012 surveys. The Baecke questionnaire was used to evaluate the physical activity fields: school, sports and leisure time. ANOVA for repeated measures was used to compare the physical activity index (PAI) in years 2010, 2012 and 2014. The Spearman correlation coefficient was used to relate PAI obtained in 2014 with previous years. Significant reduction was observed in both sexes in the total and school index in 2012 and 2014 in relation to 2010. The leisure time index also presented a significant reduction in male sex from 2012 to 2014 (p<0.05). In the correlation between 2014 and the previous years, boys demonstrated weak association in the leisure index in 2010 (rho=0.292). In the female sex, values were significant in the leisure time and total indexes (rho=0.263; rho=0.307) in 2010 and in the sports and total indexes (rho=0.337; rho=0.332) in 2012. The research indicates that PA of adolescents decreased with age advancement, resulting in low to moderate tracking.

Physical Activity and Obesity Indicators: National Cross Sectional Study on Lebanese Adults

<p>Association between higher levels of physical activity and lower rates of obesity has been shown. The aim is to assess the relation between the prevalence of physical activity and the Physical Activity Index (PAI) of 300 Lebanese healthy adults, with age, gender, occupation, body mass indices and waist circumferences (WC). The cutoff points of WC for both genders were determined using the values of Body Mass Index (BMI). A cross-sectional study using self-reported valid questionnaire was conducted randomly on 150 men and 150 women, between 18 and 74 years, from Beirut region. Association between variables was performed using chi2, T-Test and ANOVA. Linear regression determined the WC cutoffs based on BMI. 22% of the population was obese with WC mean level of 92.47±14.4cm (87.71±14.4 cm for women and 97.24±12.96 cm for men). The prevalence of physical activity was 34% in overall population (27% in women and 40% in men).There was no significant association between BMI values and PAI (p&lt; 0.085 for men and p&lt; 0.300 for women). However there was an inverse association between WC values and PAI in both genders (p&lt;0.043 in men and p&lt; 0.036 in women). Linear regression showed WC cut-off point in Lebanese women with BMI ≥25 kg/m2 and ≥30 kg/m2 of 86 cm and 100 cm respectively, whereas for men it was 92.12 cm and 105 cm respectively. The prevalence of physical activity in Beirut is low with differences among genders. The highest physical activity index is associated with the decreased values of waist circumference.</p>
