Physical inactivity in children is a major public health challenge, for which valid physical activity assessment tools are needed. Wearable devices provide a means for objective assessment of children’s physical activity, but they are often not adopted because of issues such as cost, comfort, and privacy. In this context, self-reporting tools could be employed, but their validity in relation to a child’s age is understudied. We present the agreement of one of the most popular self-reporting tools, the Physical Activity Questionnaire for Children (PAQ-C) with accelerometer-measured physical activity in 9-year-old versus 12-year-old children, wearing an accelerometer-based wearable device for seven consecutive days. We study the relationship between the PAQ-C and accelerometer scores using Spearman’s rank correlation coefficients and Bland–Altman plots in a sample of 131 children included for analysis. Overall, there was correlation between PAQ-C score and physical activity measures for the 12-year-old children (rho = 0.47 for total physical activity, rho = 0.43 for moderate-to-vigorous physical activity, rho = 0.41 for steps, p < 0.01), but not for the 9-year-old children (rho = 0.08 for total physical activity, rho = 0.21 for moderate-to-vigorous physical activity, rho = 0.19 for steps, p > 0.05). All PAQ-C items other than item 3 (activity at recess) did not reach significance in correlation with accelerometry for the 9-year-old children (p > 0.05). Therefore, the use of wearable devices for more objective assessment of physical activity in younger children should be preferred.

Background. Trends show a significant decline with adolescent physical activity (PA). Knowledge regarding how sensory-processing patterns and body mass index (BMI) relate to adolescents’ PA participation is scarce. Purpose. This study investigated if relationships exist between adolescent BMI, sensory processing, and PA participation. Method. This correlational study collected data from 141 adolescents who completed the Adolescent/Adult Sensory Profile and the Physical Activity Questionnaire–Adolescent. Their BMIs were calculated using self-reported age, height, and weight. The data were analyzed using descriptive statistics and two-tailed Spearman’s rank correlation coefficients. Findings. Adolescents with different sensory-processing patterns reported participation in both similar and distinct PAs. Participation in PA and BMI shared no significant correlation. Sensory sensitivity and BMI total ( rs = –.171, p = .044) and BMI percentile ( rs = –.191, p = .024) demonstrated significant correlations. Analysis revealed a correlation between sensory seeking patterns and PA ( rs = .224, p = .008) as well as correlations among sensory quadrants and participation in specific PAs. Implications. Occupational therapists should consider an adolescent’s sensory preferences when recommending PA interventions.

Purpose:To examine the validity and repeatability of a short leisure time physical activity (LTPA) questionnaire during pregnancy.Methods:Seventy-nine women with uncomplicated pregnancies and weeks’ gestation ≤ 33 participated. After the first questionnaire (LTPAQ1) they entered 7-day LTPA and pedometer counts in a logbook and completed the second LTPA questionnaire (LTPAQ2). Validity was assessed with Spearman’s rank correlation coefficients by comparing LTPAQ2 with pedometer counts and logbook. For describing repeatability, change in the mean, geometric mean ratio, typical error, coefficient of variation (CV, %) and Bland-Altman plots were used.Results:Forty-five (57%) and 47 (59%) women were available for pedometer and logbook comparisons and 49 (62%) for repeatability assessment. LTPAQ2 showed no correlation with pedometer but moderate correlation with the logbook for the frequency of moderate to vigorous-intensity LTPA (rs = 0.68, 95% CI 0.48 to 0.81). In repeatability, the typical error for frequency estimates varied from 1.2 to 3.7 sessions and CV for duration from 119 to 369%. The corresponding values for systematic error were -1.0 to 0.3 sessions and 4 to 36%. The 95% limits of agreement for single variables were large.Conclusions:The questionnaire was valid for assessing moderate to vigorous-intensity LTPA but its individual repeatability proved weak.

Background and Aim: The physical asymmetries associated with a prosthesis raises the question of validity of the Sensory Organization Test (SOT) measures (equilibrium score (ES) and strategy score (SS)) in lower limb amputees. This study explores the validity of these measures in transtibial amputees by correlating with their corresponding centre of pressure (COP) excursion/velocity measures. Technique: Fifteen transtibial amputees (69.5 ± 6.5 years) completed three trials for each of the six SOT conditions. Discussion: The Spearman’s rank correlation coefficients between ESs and global COP excursion/velocity measures ranged from 0.52 to 0.71 for Conditions 1, 4 and 5, 0.79 to 0.85 for Conditions 2 and 3, and 0.39 to 0.43 for Condition 6. The coefficients for SSs ranged between 0.78 and 0.97 for Conditions 1 to 5 and 0.55 to 0.67 for Condition 6. The corresponding sound and prosthetic side COP variables demonstrated varying strengths of association with ES and SS. Clinical relevance Of the two clinical measures examined, the SSs are strongly reflective of COP excursion/velocity measures and these findings have application in the interpretation of SOT when evaluating balance in transtibial amputees.

AbstractBACKGROUND:Along with time, variation in the exposome is dependent on the location and sex of study participants. One specific factor that may influence exposure co-variations is a shared household environment.OBJECTIVES:To examine the influence of shared household and partner’s sex in relation to the variation in 128 endocrine disrupting chemical (EDC) exposures among couples.METHODS:In a cohort comprising 501 couples trying for pregnancy, we measured 128 (13 chemical classes) persistent and non-persistent EDCs and estimated 1) sex-specific differences; 2) variance explained by shared household; and 3) Spearman’s rank correlation coefficients (rs) for females, males, and couples’ exposures.RESULTS:Sex was correlated with 8 EDCs including polyfluoroalkyl substances (PFASs) (p< 0.05). Shared household explained 43% and 41% of the total variance for PFASs and blood metals, respectively, but less than 20% for the remaining 11 EDC classes. Co-exposure patterns of the exposome were similar between females and males, with within-classrs higher for persistent and lower for non-persistent chemicals. Medianrss of polybrominated compounds and urine metalloids were 0.45 and 0.09, respectively, for females (0.41 and 0.08 for males), whereas lowerrss for these 2 classes were found for couples (0.21 and 0.04).CONCLUSIONS:Overall, sex did not significantly affect EDC levels in couples. Individual, rather than shared environment, could be a major factor influencing the co-variation of 128 markers of the exposome. Correlations between exposures are lower in couples than in individual partners and have important analytical and sampling implications for epidemiological study.

The Relationship

Background: The relationship between moderate to vigorous physical activity (MVPA) and fundamental motor skill (FMS) is inconsistent in early childhood, due to its complex and nonlinear characteristics. This study aimed to analyze the nonlinear relationships between MVPA, FMS, body mass index (BMI), sex, and age in preschoolers. Methods: This cross-sectional study with preschoolers (n = 204; 4.0 [0.8] y old; 99 boys), provided objective physical activity data, FMS assessments, and BMI. The associations between MVPA, FMS, BMI, sex, and age were explored using the network analysis (RStudio and qgraph). Results: Boys were more motor competent than girls in all FMS skills, while girls were more active than boys during the weekend. Older children were less active than their younger peers during these days. MVPA is weak and differently related to each FMS, and the leap skill emerged with the highest betweenness and strength values in the network. Conclusions: For the assessed preschoolers, when considering BMI, age, and sex, the relationships between MVPA and FMS are inconsistent, and leap emerged as the main variable. During early childhood, these variables are connected as part of a complex system in which each skill has a dynamic role within the emerging pattern.

This study into the behaviour of domestic cats (Feliscatus) aimed to assess the relationship between behavioural expressions obtained via the Qualitative Behaviour Assessment (QBA) and quantitative outcomes of temperament tests. Four behavioural tests were used: Unfamiliar person (UP); Novel object (NO); Conspecific reaction (CR); and Food offering (FO) tests. Tests were filmed and assessed using an ethogram that included 25 discrete behavioural categories, generating quantitative information (coding method) on the existing temperament dimensions. Videos were also assessed by another observer using the QBA method, based on a list of 20 adjectives rated in visual analogue scales (rating method). Data were analysed using Principal Component Analysis. Spearman's rank correlation coefficients were used to relate the principal components (PC) of QBA to the temperament dimensions obtained with the coding method. The QBA allowed us to identify three PC, explaining 76.63% of the total variance. PC1 ranged from 'calm/relaxed/friendly' to 'tense/fearful/alert', reflecting the valence of cats' behavioural and emotional expressions towards the stimuli tested. PC2 ranged from 'indifferent' to 'agitated/active', indicating the level of emotional arousal, and PC3 ranged from 'aggressive' to 'suspicious' and could be interpreted as an axis of 'aggressiveness — caution' in response to the stimuli. The first PC obtained for each test by using the coding method was significantly correlated with the PC1 of QBA, suggesting that the variations in cats' behavioural and emotional expressions identified by QBA were correlated with the main quantitative outcomes of temperament tests traditionally applied for domestic cats. QBA could be a promising tool for identifying and differentiating cat temperament profiles. Further research is required to assess the potential use of QBA as a feasible and practical method for use in shelters.

Dosage is essential for studying the compatibility and effectiveness of traditional Chinese medicine. Danggui and Chuanxiong are widely used in traditional Chinese medicine for ailments and treatment of various disorders. 628 traditional Chinese medicine prescriptions containing Danggui and Chuanxiong were extracted from the self-built prescription database and screened for the three groups of prescriptions, i.e., irregular menstruation, sores, and stroke. We processed and tested the dosage of Danggui and Chuanxiong and selected the optimal copula function, Gumbel copula function, from the Archimedes function family and elliptical copula function family to establish the data model. To establish the presence of a correlation between the dose of Danggui and Chuanxiong, a graph of the joint distribution function of rank correlation coefficients, Kendall’s rank correlation coefficient and Spearman’s rank correlation coefficient, was used. Our results suggest that the model using the Gumbel copula function better reflects the correlation between the dose of Danggui and Chuanxiong. For irregular menstruation, sores, and strokes, Kendall’s rank correlation coefficients were 0.6724, 0.5930, and 0.7757, respectively, and Spearman’s correlation coefficients were 0.8536, 0.7812, and 0.9285, respectively. In all three prescription groups, the dose of Danggui and Chuanxiong was positively correlated, implying that, as the dosage of one drug increases, the dosage of the other increases as well. From the perspective of data mining and mathematical statistics, the use of the copula function model to evaluate the correlation between the prescribed dosage of the two drugs was innovative and provided a new model for the scientific interpretation of the compatibility of traditional drugs. This might also serve to guide the clinical use of traditional Chinese medicine.

Abstract Introduction: Despite the importance of appropriate levels of muscular strength to maintain the functional capacity and a healthy life in old age, the current literature still lacks studies that investigate the profile of elderly women who practice Mat Pilates regarding these variables. Objective: This study aimed to analyze muscular strength, functional capacity, and risk of sarcopenia in elderly women who practiced Mat Pilates. Method: This is a cross-sectional study carried out with 50 elderly women who practice Mat Pilates in the city of Maringá, Paraná. Sociodemographic and health questionnaires were used, in addition to tests created by a Latin American development group for maturity called Grupo de Desenvolvimento Latino Americano para a Maturidade (GDLAM), sitting-rising test, arm curl test, and SARC-F questionnaire. For data analysis, Shapiro-Wilk and Mann-Whitney U tests, as well as Spearman’s Rank Correlation Coefficients, were used. The level of significance was p < 0.05. Results: The 70-79-year-old elderly women showed worse results in the functional capacity and muscular strength tests of the upper limbs and a higher risk of sarcopenia than the individuals who were under 70 years of age. Muscular strength was inversely related to the reduction of the risk of sarcopenia, and functional capacity was directly associated with this risk. Conclusion: A good functional capacity seems to be related to the reduction of the risk of sarcopenia. Age seems to be an intervening factor for reducing muscular strength levels and functional capacity and increasing the risk of sarcopenia.

We aimed to evaluate the effects of the COVID-19 lock down on lifestyle in China during the initial stage of the pandemic. A questionnaire was distributed to Chinese adults living in 31 provinces of China via the internet using a snowball sampling strategy. Information on 7-day physical activity recall, screen time, and emotional state were collected between January 24 and February 2, 2020. ANOVA, χ² test, and Spearman’s correlation coefficients were used for statistical analysis. 12,107 participants aged 18–80 years were included. During the initial phase of the COVID-19 outbreak, nearly 60% of Chinese adults had inadequate physical activity (95% CI 56.6%–58.3%), which was more than twice the global prevalence (27.5%, 25.0%–32.2%). Their mean screen time was more than 4 hours per day while staying at home (261.3 ± 189.8 min per day), and the longest screen time was found in young adults (305.6 ± 217.5 min per day). We found a positive and significant correlation between provincial proportions of confirmed COVID-19 cases and negative affect scores (r = 0.501, p = 0.004). Individuals with vigorous physical activity appeared to have a better emotional state and less screen time than those with light physical activity. During this nationwide lockdown, more than half of Chinese adults temporarily adopted a sedentary lifestyle with insufficient physical activity, more screen time, and poor emotional state, which may carry considerable health risks. Promotion of home-based self-exercise can potentially help improve health and wellness.

This paper aims to investigate the agricultural trade complementarity of the Association of Southeast Asian Nations (ASEAN) countries on the global agricultural market over the period 1997–2015 by employing the trade complementarity index (TCI), the export similarity index (ESI), and Spearman’s rank correlation coefficients for competitiveness indicators. The results indicate that: (i) the ASEAN countries’ agricultural export patterns are weakly complementary in matching the regional import demands; while (ii) they are relatively complementary in exporting agricultural products to the world market; (iii) the countries’ agricultural competitiveness patterns are more affected by and benefited from the global integration than the regional integration; and (iv) the countries, moreover, tend to become more substitutable over time. The research results suggest that the ASEAN countries should cooperate and utilise the internal markets to enhance the competitiveness and predominantly focus on the external global markets.
