Abstract
Infants born to mothers with type 2 diabetes (T2D) and gestational diabetes (GDM) are at an increased risk of being overweight/obese. Modifiable lifestyle factors play a role in prevention of overweight and obesity. In 2017, the Canadian 24 h Movement Guidelines for the Early Years (CMG) were released. Alongside physical activity recommendations, sweetened beverage consumption (SBC) recommendations were also released by the American Academy of Pediatrics in 2017. The objective of this study was to determine the knowledge pregnant women with T2D and GDM have on the CMG and SBC recommendations, and to determine what factors affect this. A survey with questions regarding demographics, socioeconomic variables and the CMG and SBC recommendations was administered to pregnant women at Diabetes in Pregnancy clinics in Calgary, Alberta from July 2019 to January 2020. Surveys were analyzed utilizing the non-parametric Kruskall-Wallis Rank-Sum test, chi-square test and linear regression. A total of 79 respondents with T2D and GDM were collected. Respondents had the highest knowledge of SBC recommendations and the lowest knowledge of CMG recommendations. A bachelor's or higher degree was associated with significantly higher knowledge scores than a high-school education or less. In conclusion, pregnant women with T2D and GDM in this study had overall poor knowledge of the CMG and SBC recommendations, with less knowledge regarding the CMG. Level of education was found to be associated with knowledge regarding these recommendations. Future programs to improve education around infant and toddler physical activity and SBC recommendations may be beneficial for this patient population.

Abstract
BACKGROUND AND AIMS Objective assessment of physical activity (PA) using accelerometers and pedometers has become more accurate and common practice in the study of childhood overweight. The study aimed: i) to compare PA levels and body shape of boys and girls, and assess compliance of active children with the PA recommendation; ii) to analyse associations between the risk of overweight and the moderate-to-vigorous physical activity (MVPA) in children. METHODS The sample comprised 395 children (198 girls) aged 6-10 years. Height and weight were measured, and BMI was calculated subsequently. A tri-axial accelerometer was used to obtain seven consecutive days of MVPA, as well as the weekly time being sedentary. Logistic regression analysis was used to examine the afore-mentioned relationship among the risk of obesity and MVPA, controlling for confounders. RESULTS After controlling for wearing time, boys spent significantly more minutes in the moderate-to-vigorous portion of PA than their female counterparts. About 47% of boys were active on week days by achieve the mean value of 60 min/day of MVPA; corresponding percentage for the weekend was just 32%. Among girls, only 22% were active on week days and 29% at the weekend. MVPA was not significantly associated with the risk of being overweight nor in female neither in male children. The final regression model revealed that girls of mothers with high educational level were less likely to be classified as overweight girls. CONCLUSIONS Findings revealed no significantly relation between MVPA and obesity risk among Portuguese children. Future research should extend similar design to other lifestyle features of children to clarify potential predictors of being overweight at early ages.

Abstract
Background Physical activity is a multifactorial trait, determined by both individual and environmental characteristics, it seems relevant to understand the determinants related to youth guidelines accomplishment. The present study aimed to verify the differences between the Brazilian federative units regarding to the prevalence of youth physical activity guidelines accomplishment and to investigate the determinants related to the inter-individual differences in this accomplishment. Methods Sample comes from the 2015 Brazilian National School Health Survey (PeNSE), comprising 99,570 adolescents (51,527 girls, 13-17y), enrolled in 3039 schools. Adolescents reported the time they spend in moderate-to-vigorous physical activity daily, and they were categorized as active or inactive, if the guidelines were achieved, or not, respectively, and multilevel statistical analyses were used, including both child and school-level variables. Multilevel Binomial model was computed in the SuperMix software. Results The majority of the adolescents did not comply with the physical activity guidelines daily, where Bahian children complied the least, while those from Amazonas, Tocantins, and Mato Grosso do Sul complied the most. Boys (OR: 2.305; 95%CI: 2.277-2.334), older adolescents (OR: 1.044; 95%CI: 1.036-1.051), and those who spent more time in active travelling to/from school (OR: 1.001; 95%CI: 1.001-1.001) complied more the physical activity guidelines. At the school level, adolescents from larger schools (OR: 0.957; 95%CI: 0.928-0.986) tended to comply less with the guidelines. Conclusion Significant differences between Brazilian federative units in youth daily physical activity guidelines compliance were observed, highlighting the role of individual but also environmental constraints in the Brazilian adolescents’ engagement in physical activity.

Abstract
The purpose of this study was to measure the factors that influence children’s moderate-to-vigorous physical activity (MVPA) during school curriculum time, recess time, and outside school time in a rural area. During the Fall and Winter of 2016, 34 boys and 55 girls aged 8–14 years from rural communities in rural Northwestern Ontario participated in the Spatial Temporal Environment and Activity Monitoring project. The children’s MVPA was measured using an accelerometer, and child-level demographic, behavioral, and environmental data were gathered from surveys, passively logging global positioning units, and municipal datasets. Data on daily temperature and precipitation were gathered from the closest Environment Canada weather station. A mixed model was used to assess the relationship between child- and day-level factors and children’s MVPA. On average, children were getting 12.9 min of MVPA during recess, 17.7 min during curriculum time, and 29.0 min of MVPA outside school time. During all three time points, boys were more active than girls. During curriculum time, children in lower grades were more active, and the weather had differing impacts depending on the time of day. The findings of this study illustrate the differences in MVPA and the factors that influence MVPA by time of day. Examining different time segments provides valuable information for understanding children’s MVPA patterns.

Abstract
O objetivo foi identificar desigualdades na prática de atividade física de lazer e deslocamento ativo para escola em adolescentes brasileiros, bem como suas tendências de acordo com o sexo, tipo de escola, escolaridade materna e regiões geográficas de 2009 a 2015. Estudo descritivo baseado em dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2009, 2012 e 2015. Foram considerados ativos no lazer aqueles que acumularam, no mínimo, 60 minutos por dia, em cinco ou mais dias da semana anteriores à entrevista. Para deslocamento ativo para escola, foi avaliado o transporte a pé ou de bicicleta para a escola na semana anterior à entrevista. Os desfechos foram estratificados pelo sexo, tipo de escola, escolaridade materna e regiões geográficas. As desigualdades foram avaliadas por meio de diferenças e razões entre as estimativas, bem como por índices sumários de desigualdade. Foram incluídos na PeNSE 2009, 2012 e 2015, 61.301, 61.145 e 51.192 escolares, respectivamente. A prevalência de atividade física de lazer foi 13,8% em 2009, 15,9% em 2012 e 14,7% em 2015; já para o deslocamento ativo para escola, foi 70,6%, 61,7%, 66,7%, respectivamente. Meninos apresentaram uma prevalência de 10 pontos percentuais (p.p.) maior de atividade física de lazer e cerca de 5p.p. no deslocamento ativo para escola do que as meninas. Escolares filhos de mães com maior escolaridade apresentaram, em média, uma prevalência de atividade física de lazer 10p.p. maior do que seu grupo extremo de comparação e cerca de 30p.p. menor com relação ao deslocamento ativo para escola. As desigualdades observadas permaneceram constantes ao longo do período avaliado. Foram identificadas desigualdades socioeconômicas e entre os sexos, que se mantiveram constantes ao longo do período analisado e que foram específicas para cada domínio de atividade física.

Abstract
Background Children’s activity level, including physical activity (PA) and screen sedentary time (SST), is influenced by environmental factors in which parents play a critical role. Different types of parenting styles may influence children’s activity level. Inconsistent results were found on the association between parenting styles and PA, and few studies tested the association between parenting styles and SST. This study examined the association between parenting styles, PA and SST and the modifying effect of children’s gender and maternal educational level on these associations. Methods Cross-sectional data were collected from parents of children aged 8–11 years old who completed a web-based non-standardized questionnaire (N = 4047). Since 85% of the questionnaires were filled in by mothers, parenting styles are mainly reported by mothers. Multiple linear regression techniques were used to assess the associations between parenting styles (authoritative, permissive, authoritarian and neglectful), and PA and SST (mean min/day). The modifying effect of children’s gender and maternal educational level on these associations was explored. P values ≤.0125 were considered as statistically significant based on the Bonferroni correction for four primary analyses. Results The neglectful parenting style was most widely used (35.3%), while the authoritarian style was least common (14.8%). No significant association was found between parenting styles and PA level. As regards SST, an authoritative parenting style was significantly associated with lower SST in boys while a neglectful parenting style was significantly associated with higher SST in both boys and girls. When the mother had a medium educational level, an authoritative parenting style was significantly associated with lower SST while neglectful parenting was significantly associated with higher SST. Conclusions No association was found between parenting styles and PA. However, an authoritative parenting style was associated with a reduction in SST and a neglectful parenting style with an increase in SST, especially in boys and in children whose mother had a medium education level. Future studies of parenting practices are needed to gain more insight into the role of parents in children’s PA and SST levels, as a basis for the development of interventions tailored to support parents in stimulating PA and reducing SST in children.

Understanding differences between summer vs. school obesogenic behaviors of children: the structured days hypothesis. Int J Behav Nutr Phys Act 2017; 14:100.

Abstract
BACKGROUND Although the scientific community has acknowledged modest improvements can be made to weight status and obesogenic behaviors (i.e., physical activity, sedentary/screen time, diet, and sleep) during the school year, studies suggests improvements are erased as elementary-age children are released to summer vacation. Emerging evidence shows children return to school after summer vacation displaying accelerated weight gain compared to the weight gained occurring during the school year. Understanding how summer days differ from when children are in school is, therefore, essential. DISCUSSION There is limited evidence on the etiology of accelerated weight gain during summer, with few studies comparing obesogenic behaviors on the same children during school and summer. For many children, summer days may be analogous to weekend days throughout the school year. Weekend days are often limited in consistent and formal structure, and thus differ from school days where segmented, pre-planned, restrictive, and compulsory components exist that shape obesogenic behaviors. The authors hypothesize that obesogenic behaviors are beneficially regulated when children are exposed to a structured day (i.e., school weekday) compared to what commonly occurs during summer. This is referred to as the 'Structured Days Hypothesis' (SDH). To illustrate how the SDH operates, this study examines empirical data that compares weekend day (less-structured) versus weekday (structured) obesogenic behaviors in U.S. elementary school-aged children. From 190 studies, 155 (~80%) demonstrate elementary-aged children's obesogenic behaviors are more unfavorable during weekend days compared to weekdays. CONCLUSION In light of the SDH, consistent evidence demonstrates the structured environment of weekdays may help to protect children by regulating obesogenic behaviors, most likely through compulsory physical activity opportunities, restricting caloric intake, reducing screen time occasions, and regulating sleep schedules. Summer is emerging as the critical period where childhood obesity prevention efforts need to be focused. The SDH can help researchers understand the drivers of obesogenic behaviors during summer and lead to innovative intervention development.

Abstract
Background Targeting specific time periods of the day or week may enhance physical activity (PA) interventions in youth. The most prudent time segments to target are currently unclear. Objectives To systematically review the literature describing differences in young people’s objectively measured PA on weekdays vs. weekends, in school vs. out of school, weekends vs. out of school and lesson time vs. break time. Methods Electronic databases were searched for English-language, cross-sectional studies of school-aged children (4–18 years) reporting time-segment-specific accelerometer-measured PA from 01/1990 to 01/2013. We meta-analysed standardised mean differences (SMD) between time segments for mean accelerometer counts per minute (TPA) and minutes in moderate-to-vigorous PA (MVPA). SMD is reported in units of standard deviation; 0.2, 0.5 and 0.8 represent small, moderate and large effects. Heterogeneity was explored using meta-regression (potential effect modifiers: age, sex and study setting). Results Of the 54 included studies, 37 were eligible for meta-analyses. Children were more active on weekdays than weekends [pooled SMD (95 % CI) TPA 0.14 (0.08; 0.20), MVPA 0.42 (0.35; 0.49)]. On school days, TPA was lower in school than out of school; however, marginally more MVPA was accumulated in school [TPA −0.24 (−0.40; −0.08), MVPA 0.17 (−0.03; 0.38)]. TPA was slightly lower on weekends than out of school on school days, but a greater absolute volume of MVPA was performed on weekends [TPA −0.10 (−0.19; −0.01), MVPA 1.02 (0.82; 1.23)]. Heterogeneity between studies was high (I2 73.3–96.3 %), with 20.3–53.1 % of variance between studies attributable to potential moderating factors. Conclusions School-aged children are more active on weekdays than weekend days. The outcome measure influences the conclusions for other comparisons. Findings support the tailoring of intervention strategies to specific time periods.

Abstract
OBJECTIVE The positive impacts of active travel on health markers still require further research, especially in youth populations with higher risk of obesity. The present study aimed to analyze the associations between blood pressure and adiposity risk (BPAR) and active travel to school in children. METHODS The sample comprised 665 Portuguese children (345 boys) aged 7-9 years. Data on height, weight, and skinfold thickness were collected by a trained fieldworker as well as data on BPAR between March 2009 and January 2010 (data were analyzed in 2012-2013). Information on mode and duration of travel to school (i.e. exposure) was gathered by questionnaire. Outcome variables were statistically normalized and expressed as Z scores. A BPAR score was computed as the mean of the Z scores. Multiple linear regression, with adjustments for confounders, was used. RESULTS Active commuting was inversely associated with BPAR after adjustment for several potential confounders. After adjusting for BMI, the strength of the relationship between BPAR and active commuting was significantly improved (p≤0.01). CONCLUSIONS Findings showed an independent association between the clustered BPAR and active commuting in children aged 7-9 years.

Abstract
OBJECTIVES To evaluate the impact of the chronic kidney disease (CKD) on quality of life, from the children's and their parents' perspective, respiratory muscle strength, lung function, and functional capacity in children and adolescents. METHOD Cross-sectional study of children with CKD aged 8 to 17 years. Those incapable of taking the tests were excluded. After an interview, quality of life by Pediatric Quality of Life Inventory) (PedsQL(TM)), muscular strength, pulmonary function tests, and the 6-minute walking test (6MWT) were applied. Student's t-test, ANOVA (difference in means), and Pearson's coefficient of correlation were used. The level of significance was set at 5%. RESULTS Of the 40 patients, the mean distance walked at the 6MWT was 396 meters, and the mean final score at the quality of life test as perceived by the children and parents was 50.9 and 51, respectively. From the children's perspective, the transplanted patients had a higher quality of life score when compared to those undergoing hemodialysis (p<0.001); those who practiced physical activity had better quality of life when compared to the sedentary children (p<0.001). From the children's and the parents' perspectives, the male gender had a higher quality of life score (p<0.05). There was a positive correlation between the distance walked at the 6MWT and age, height, final PedsQL(TM), forced vital capacity (FVC), and forced expiratory volume in the first second (FEV1), as well as a negative correlation between FEV1/FVC and the distance walked. CONCLUSION A significant reduction in the quality of life and the functional capacity was observed in children with CKD, influenced by the type of treatment, gender, and sedentary life style.

Abstract
OBJECTIVE To determine the association between family structure, maternal education level, and maternal employment with sedentary lifestyle in primary school-age children. METHOD Data were obtained from 897 children aged 6 to 12 years. A questionnaire was used to collect information. Body mass index (BMI) was determined using the age- and gender-specific Centers for Disease Control and Prevention definition. Children were categorized as: normal weight (5(th) percentile≤BMI<85(th) percentile), at risk for overweight (85(th)≤BMI<95(th) percentile), overweight (≥ 95(th) percentile). For the analysis, overweight was defined as BMI at or above the 85(th) percentile for each gender. Adjusted odds ratios (adjusted ORs) for physical inactivity were determined using a logistic regression model. RESULTS The prevalence of overweight was 40.7%, and of sedentary lifestyle, 57.2%. The percentage of non-intact families was 23.5%. Approximately 48.7% of the mothers had a non-acceptable educational level, and 38.8% of the mothers worked outside of the home. The logistic regression model showed that living in a non-intact family household (adjusted OR=1.67; 95% CI=1.04-2.66) is associated with sedentary lifestyle in overweight children. In the group of normal weight children, logistic regression analysis show that living in a non-intact family, having a mother with a non-acceptable education level, and having a mother who works outside of the home were not associated with sedentary lifestyle. CONCLUSION Living in a non-intact family, more than low maternal educational level and having a working mother, appears to be associated with sedentary lifestyle in overweight primary school-age children.

Abstract
Research considering physical activity (PA), physical inactivity and health outcomes among urban and rural youth has produced equivocal findings. This study examined PA, physical inactivity, sedentary behaviours and cardiorespiratory fitness (CRF) in adolescents from urban and rural communities in the Portuguese Midlands. The sample included 362 adolescents (165 males, 197 females) of 13-16 years of age. CRF was assessed by the PACER test. A GT1M accelerometer was used to record 5 consecutive days of PA and time spent sedentary. Analyses of covariance (chronological age as co-variate) were performed to test the effect of the area of residence on sedentary behaviour, PA and CRF. Urban youth of both sexes spent less time in sedentary activities than rural youth. Urban males were more active than rural peers at the weekend, whereas urban females were significantly less active than rural females on week days and across all days assessed. Rural youth of both sexes had higher levels of CRF than urban youth. Area of residence was related to aerobic fitness, PA and time spent in sedentary behaviours among Portuguese youth. Interventions seeking to enhance health and active lifestyles in Portuguese youth should consider the potential impact of socio-geographic factors.

Abstract
BACKGROUND AND OBJECTIVES Data on physical activity are limited in children with CKD. The objectives of this study were to measure the level and correlates of physical activity in children and young adults with CKD and to determine the association of physical activity with physical performance and physical functioning. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Physical activity was measured for 7 days using pedometers; physical performance was measured by the 6-minute walk distance (6MWD) and physical functioning with the PedsQL 4.0. RESULTS Study participants were 44 patients 7-20 years of age who had CKD stage 1-4 (n=12), had ESRD and were undergoing dialysis (n=7), or had undergone kidney transplantation (n=25). Participants were very sedentary; they walked 6218 (interquartile range, 3637, 9829) steps per day, considerably less than recommended. Physical activity did not differ among participants in the CKD stage 1-4, ESRD, and transplant groups. Females were less active than males (P<0.01), and physical activity was 44% lower among young adults (18-20 years) than younger participants (P<0.05). Physical activity was associated positively with maternal education and hemoglobin concentration and inversely with body mass index. Respective 6MWD in males and females was 2 and approximately 4 SDs below expected. Low levels of physical activity were associated with poor physical performance and physical functioning, after adjustment for age, sex, and body mass index. CONCLUSIONS In most participants with CKD, physical activity was considerably below recommended levels. Future studies are needed to determine whether increasing physical activity can improve physical performance and physical functioning.

Abstract
We investigated whether physical activity (PA) correlates differed for 9-10 year-old British children living in urban, suburban and rural settings. We analysed cross-sectional data on 1653 children (SPEEDY study). Exposure variables were self-reported, whilst PA was measured using Actigraph accelerometers. Data were analysed using multilevel hierarchical regression models, stratified by home setting. PA levels did not differ by home setting. Boys, those of normal weight and those having a preference for PA had higher PA levels in all strata, but additional correlates were identified within each setting. These results highlight the potential importance of tailoring interventions to specific environmental and population strata.

Abstract
BACKGROUND Improving physical fitness is often an objective of programmes aimed at preventing obesity among youth. AIM To evaluate the association between cardiorespiratory fitness (CRF) and area of residence controlling for several correlates in adolescents. SUBJECTS AND METHODS CRF was assessed with the progressive aerobic cardiovascular endurance run (PACER) test in a cross-sectional sample of 362 Portuguese adolescents (165 males, 197 females) of 13-16 years of age. Youth were classified by area of residence as urban or rural. Gender, age, weight status, parental education, screen time (inactivity) and moderate-to-vigorous physical activity (MVPA) were statistically controlled. Logistic regression analysis was used. RESULTS Adolescents of both sexes from rural settings were 76% more likely to be classified as aerobically fit compared to those from urban areas. The odds ratio for CRF in the final model was similar in boys (OR = 0.24, 95% CI 0.06-0.99, p < 0.05) and girls (OR = 0.24, 95% CI 0.07-0.76, p < 0.05). MVPA and weight status were important predictors of CRF in Portuguese adolescents of 13-16 years of age. Maternal education was an additional predictor in girls. CONCLUSION CRF and rural/urban settings were significantly related in this sample of Portuguese adolescents of both sexes.
