Over the last decade, the lives of children in several countries, including Greece, have been affected by recession. The aim of the present study was (a) to examine time trends in physical activity (PA) and screen time (ST) of Greek preschool children, together with their family affluence (FA), from 2009 until 2018, and to explore the associations among them; and (b) to investigate the connections of parental educational level and children's BMIs to their achieving ST (<1h/day) and PA (11,500 st ...[more]

Project description:BACKGROUND:Dramatic increases in child overweight have occurred in China. A comprehensive look at trends in physical activity and sedentary behaviors among Chinese youth is needed. The study aimed to examine trends in domain-specific physical activity and sedentary behaviors, explore mean and distributional changes in predicted behaviors over time, and investigate how behaviors vary by residence. METHODS:Using 2004-2011 China Health and Nutrition Survey data, adjusted means for MET-hours/week from physical activity and hours/week from sedentary behaviors were determined for school children (6-18 years), stratifying by gender, age group, and residence. Physical activity domains included in-school physical activity, active leisure (out-of-school physical activity), active travel (walking or biking), and domestic activity (cooking, cleaning, and child care). For each physical activity domain, the MET-hours/week measure was determined from the total weekly time spent (hours) in domain-specific activities and corresponding MET-values using the Compendium of Energy Expenditures for Youth. Sedentary behaviors included television, computer use, homework, and other behaviors (board games, toys, extracurricular reading and writing). For each sedentary behavior, the hours/week measure was determined from total weekly time spent in specific sedentary behaviors. Residence groups included megacities (population ? 20million), cities/towns (300,000 ? population < 20million), and rural/suburban areas (population < 300,000). Repeated measure linear mixed and quantile regression models were used to predict adjusted means. RESULTS:Little change in physical activity behaviors occurred over time, with the exception of statistically significant trends toward increased domestic activity among male children (p < .05). Across all gender and age groups, statistically significant trends over time toward an average increase in computer use were seen (p < .01); these increases were largely driven by those ?50th percentile on the distribution. Children living in megacities (versus rural areas) reported higher levels of physical activity, homework, and computer use. CONCLUSIONS:Intensified, systematic intervention and policy efforts promoting physical activity and reducing sedentary behaviors among children are needed.

Project description:BackgroundKnowledge of developmental trends in meeting age-specific 24-hour movement behaviour guidelines is lacking. This study describes developmental trends in device-measured physical activity and sedentary time over a three-year period among Western Australian children aged two to seven years, including differences between boys and girls. The proportion of children meeting age-specific physical activity guidelines before and after they transition to full-time school was also examined.MethodsData from waves 1 and 2 of the Play Spaces and Environments for Children's Physical Activity (PLAYCE) cohort study were used (analysis n = 1217). Physical activity and sedentary time were measured by accelerometry at ages two to five (preschool, wave 1) and ages five to seven (commenced full-time school, wave 2). Accelerometer data were processed using a validated machine-learning physical activity classification model. Daily time spent in sedentary behaviour, energetic play (moderate-to-vigorous physical activity (MVPA)), total physical activity, and meeting physical activity guidelines were analysed using linear and generalised linear mixed-effects models with age by sex interaction terms.ResultsAll movement behaviours changed significantly with increasing age, and trends were similar in boys and girls. Total daily physical activity increased from age two to five then declined to age seven. Mean daily total physical activity exceeded 180 min/day from ages two to five. Daily energetic play increased significantly from age two to seven, however, was below 60 min/day at all ages except for seven-year-old boys. Daily sedentary time decreased to age five then increased to age seven but remained lower than at age two. All two-year-olds met their age-specific physical activity guideline, decreasing to 5% of girls and 6% of boys at age four. At age seven, 46% of boys and 35% of girls met their age-specific physical activity guideline.ConclusionsYoung children's energetic play and total physical activity increased with age, but few children aged three to seven met the energetic play (MVPA) guideline. Interventions should focus on increasing children's energetic play in early childhood. Clearer guidance and strategies are needed to support young children as they change developmentally and as they transition from one age-specific movement guideline to the next.

Project description:This study aimed to investigate associations of objectively measured physical activity (PA) and sedentary time with adiposity in a predominantly biethnic (South Asian and White British) sample of young children.The sample included 333 children age 11 months to 5 yr who provided 526 cross-sectional observations for PA and body composition. Total PA volume (vector magnitude counts per minute), daily time at multiple intensity levels (the cumulative time in activity >500, >1000, >1500, …, >6000 counts per minute), and time spent sedentary (<820 counts per minute), in light PA (820-3907 counts per minute) and in moderate-to-vigorous PA (?3908 counts per minute) were estimated with triaxial accelerometry. Indicators of adiposity included body mass index, waist circumference, and the sum of subscapular and triceps skinfold thicknesses. Statistical analyses were performed using multilevel regression and isotemporal substitution models adjusted for confounders. Effect modification by ethnicity was examined.There was no evidence for effect modification by ethnicity (P interaction ? 0.13). In the whole sample, the accumulated time spent above 3500 counts per minute (i.e., high light-intensity PA) was inversely associated with the sum of skinfolds (? = -0.60 mm, 95% confidence interval [CI] = -1.19 to -0.021, per 20 min·d), and the magnitude of association increased dose dependently with PA intensity (peaking for time spent >6000 counts per minute = -1.57 mm, 95% CI = -3.01 to -0.12, per 20 min·d). The substitution of 20 min·d of sedentary time with moderate-to-vigorous PA was associated with a lower sum of skinfolds (-0.77 mm, 95% CI = -1.46 to -0.084).High light-intensity PA appears to be beneficial for body composition in young South Asian and White British children, but higher-intensity PA is more advantageous.

Project description:ObjectiveThis cross-sectional study examined environmental correlates of sedentary behavior (SB) and physical activity (PA) in preschool children in the urban area of Tianjin, China.MethodsData were collected from the Physical Activity and Health in Tianjin Chinese Children study, involving healthy children 3-6 years old and their families. In all children (n = 980), leisure-time SB (LTSB) and leisure-time PA (LTPA) were reported in min/day by parents. In a subgroup (n = 134), overall sedentary time, light PA, and moderate-to-vigorous PA (MVPA) were objectively measured using ActiGraph accelerometry (≥3 days, ≥10 h/day). Environmental correlates were collected using a questionnaire that included home and neighborhood characteristics (e.g., traffic safety, presence of physical activity facilities) and children's behaviors. Potential correlates were identified using linear regression analysis.ResultsMultiple linear regression analysis showed that "having grandparents as primary caregivers" (βs and 95% confidence intervals (95%CIs) for overall sedentary time: 29.7 (2.1-57.2); LTSB (ln): 0.19 (0.11-0.28)) and "having a television (for LTSB (ln): 0.13 (0.00-0.25)) or computer (for LTSB (ln): 0.13 (0.03-0.23)) in the child's bedroom" were both associated with higher SB. Furthermore, "having grandparents as primary caregivers" was associated with less MVPA (β (95%CI): -7.6 (-14.1 to -1.2)), and "active commuting to school by walking" correlated with more MVPA (β (95%CI): 9.8 (2.2-17.4)). The path model showed that "more neighborhood PA facilities close to home" was indirectly related to higher LTPA (ln), which was partly mediated by "outdoor play" (path coefficients (95%CI): 0.005 (0.002-0.008)) and "going to these facilities more often" (path coefficients (95%CI): 0.013 (0.008-0.018)). Traffic safety was not a correlate.ConclusionFamily structure and media exposure in the home maybe important factors in shaping preschoolers' PA patterns. Built environmental correlates could indirectly influence preschoolers' LTPA through parental help with engaging in active behaviors.

Project description:PURPOSE:Many children attend family child care homes (FCCHs), an important setting to influence children's physical activity (PA) and sedentary behavior (SB). This study assessed children's PA and SB while in FCCHs, characteristics of the FCCH PA environment, and relationships between the environment and child PA and SB. METHOD:Children ages 1.5-4.0 years (n?=?495) were recruited from 165 FCCHs in North Carolina. Children's moderate to vigorous PA and SB were measured via accelerometry for 3 days. FCCH PA environments were assessed over 2 days using the Environment and Policy Assessment and Observation for FCCHs. Ten subscores and an overall PA environment score (possible range: 0-30) were calculated; higher scores indicate better quality. RESULTS:Children accumulated 30 (13) minutes of moderate to vigorous PA and 143 (42) minutes of SB in FCCHs daily. FCCHs scored low on the Environment and Policy Assessment and Observation for FCCHs, with an average overall score of 13 (2). FCCHs scored highest on screen time and screen time practices subscores, and lowest on PA education/professional development and PA policy subscores. Although no statistically significant associations were observed, some large Cohen d effect sizes were noted (eg, outdoor playtime subscore and moderate to vigorous PA). CONCLUSIONS:This study highlights opportunities to improve FCCHs and increase children's behaviors (eg, providing adequate time and outdoor play spaces).

Project description:ObjectiveTo examine recent national trends in psychotropic use for very young children at US outpatient medical visits.MethodsData for 2- to 5-year-old children (N = 43 598) from the 1994-2009 National Ambulatory and National Hospital Ambulatory Medical Care Surveys were used to estimate the weighted percentage of visits with psychotropic prescriptions. Multivariable logistic regression was used to identify factors associated with psychotropic use. Time effects were examined in 4-year blocks (1994-1997, 1998-2001, 2002-2005, and 2006-2009).ResultsPsychotropic prescription rates were 0.98% from 1994-1997, 0.83% from 1998-2001, 1.45% from 2002-2005, and 1.00% from 2006-2009. The likelihood of preschool psychotropic use was highest in 2002-2005 (1994-1997 adjusted odds ratio [AOR] versus 2002-2005: 0.67; 1998-2001 AOR versus 2002-2005: 0.63; 2006-2009 AOR versus 2002-2005: 0.64), then diminished such that the 2006-2009 probability of use did not differ from 1994-1997 or from 1998-2001. Boys (AOR versus girls: 1.64), white children (AOR versus other race: 1.42), older children (AOR for 4 to 5 vs 2 to 3 year olds: 3.87), and those lacking private insurance (AOR versus privately insured: 2.38) were more likely than children from other groups to receive psychotropic prescriptions.ConclusionsPsychotropic prescription was notable for peak usage in 2002-2005 and sociodemographic disparities in use. Further study is needed to discern why psychotropic use in very young children stabilized in 2006-2009, as well as reasons for increased use in boys, white children, and those lacking private health insurance.

Project description:BackgroundAmerican women tend to reduce physical activity (PA) during the transition to motherhood. Their main barrier to participation in PA is lack of time due to new/increased parenting and housework responsibilities. Because there are known racial/ethnic variations in time spent on housework among American women, their PA changes during the transition to motherhood might also differ by racial/ ethnic background. This study aimed to compare PA between American mothers of young child(ren) under age 5 years (YC) and American women without children by their racial/ethnic background.MethodsSecondary data analyses were conducted using 2011-2018 US National Health and Nutrition Survey data. The study sample included 4,892 women aged 20-45 years (Asian n = 760; Black n = 1,162; Hispanic n = 1,324; White n = 1,646). Participants completed a Physical Activity Questionnaire that asked about participation in transportation and leisure-time moderate- and vigorous-intensity PA (MVPA; minutes/week). Multivariable regression analyses were conducted to compare MVPA among women living without children and with YC (no older children) in each of the racial/ethnic groups.ResultsOverall, the prevalence of physical inactivity, defined as zero minutes of MVPA in a typical week, was 43% (95% CI = 38-49%) vs. 32% (95% CI = 29-35%) among women living with YC vs. without children. The adjusted odds of physical inactivity for women living with YC, compared to women living without children, was significantly higher among Asian (OR = 2.08 [95% CI = 1.37-3.17]) and White women (OR = 1.63 [95% CI = 1.11-2.38]), while it was statistically insignificant among Hispanic and Black women. Among women who reported participating in MVPA, Asian women living with YC had 35 fewer minutes/week of MVPA than their counterparts living without children (p = 0.06), while other racial and ethnic groups showed no significant differences.ConclusionsAmerican mothers of YC were less likely to engage in transportation or leisure-time MVPA, compared to those living without children. This association was particularly strong among Asian women. The study results suggest that a PA reduction in the transition to motherhood may be particularly large among Asian American women, calling for targeted efforts for PA promotion among Asian American mothers of YC; e.g., culturally-tailored community-based physical activity programs for Asian American mothers.

Project description:Background. This study examines factors associated with physical activity (PA) and sedentary behaviors (SB) in young adults (18-35 years) and compares objective and subjective assessment measures of PA and SB. Methods. 595 young adults (27.7 ± 4.4 years; 25.5 ± 2.6?kg/m2) enrolled in the Study of Novel Approaches to Weight Gain Prevention (SNAP) trial. Hours/day spent in SB (<1.5?METs) and minutes/week spent in bout-related moderate-to-vigorous intensity PA (MVPA; ?3?METs and ?10?min) were assessed using self-report and objective measures. Demographic factors associated with SB and MVPA were also explored (i.e., age, gender, BMI, ethnicity, work and relationship status, and number of children). Results. Objective MVPA (263 ± 246?min/wk) was greater than self-report estimates (208 ± 198?min/wk; p < 0.001) and differed by 156 ± 198?min/wk at the individual level (i.e., the absolute difference). Females, overweight participants, African Americans, and those with children participated in the least amount of MVPA. Objective estimates of SB (9.1 ± 1.8?hr/day; 64.5% of wear time) were lower than subjective estimates (10.1 ± 3.5?hr/day; p < 0.001), differing by 2.6 ± 2.5?hr/day for each participant. Conclusion. Young adults interested in weight gain prevention engage in both high levels of MVPA and SB, with participants self-reporting fewer MVPA minutes and more SB compared to objective estimates. This study is registered at ClinicalTrials.gov (NCT01183689).

Project description:PurposeTo provide an overview of relationships between sedentary behavior and mortality as well as incidence of several noncommunicable diseases and weight status reported in the 2018 Physical Activity Guidelines Advisory Committee Scientific Report (2018 PAGAC Scientific Report), and to update the evidence from recent studies.MethodsEvidence related to sedentary behavior in the 2018 PAGAC Scientific Report was summarized, and a systematic review was undertaken to identify original studies published between January 2017 and February 2018.ResultsThe 2018 PAGAC Scientific Report concluded there was strong evidence that high amounts of sedentary behavior increase the risk for all-cause and cardiovascular disease (CVD) mortality and incident CVD and type 2 diabetes. Moderate evidence indicated sedentary behavior is associated with incident endometrial, colon and lung cancer. Limited evidence suggested sedentary behavior is associated with cancer mortality and weight status. There was strong evidence that the hazardous effects of sedentary behavior are more pronounced in physically inactive people. Evidence was insufficient to determine if bout length or breaks in sedentary behavior are associated with health outcomes. The new literature search yielded seven new studies for all-cause mortality, two for CVD mortality, two for cancer mortality, four for type 2 diabetes, one for weight status, and four for cancer; no new studies were identified for CVD incidence. Results of the new studies supported the conclusions in the 2018 PAGAC Scientific Report.ConclusionsThe results of the updated search add further evidence on the association between sedentary behavior and health. Further research is required on how sex, age, race/ethnicity, socioeconomic status, and weight status may modify associations between sedentary behavior and health outcomes.

Project description:ObjectiveTo analyze physical activity and sedentary behavior in preschool children during their stay at school and the associated factors.Methods370 preschoolers, aged 4 to 6 years, stratified according to gender, age and school region in the city of Londrina, PR, participated in the study. A questionnaire was applied to principals of preschools to analyze the school infrastructure and environment. Physical activity and sedentary behavior were estimated using accelerometers for five consecutive days during the children's stay at school. The odds ratio (OR) was estimated through binary logistic regression.ResultsAt school, regardless of age, preschoolers spend relatively more time in sedentary behaviors (89.6%-90.9%), followed by light (4.6%-7.6%), moderate (1.3%-3.0%) and vigorous (0.5%-2.3%) physical activity. The indoor recreation room (OR=0.20; 95%CI 0.05 to 0.83) and the playground (OR=0.08; 95%CI 0.00 to 0.80) protect four-year-old schoolchildren from highly sedentary behavior. An inverse association was found between the indoor recreation room and physical activity (OR=0.20; 95%CI 0.00 to 0.93) in five-year-old children. The indoor recreation room (OR=1.54; 95%CI 1.35 to 1.77), the playground (OR=2.82; 95%CI 1.14 to 6.96) and the recess (OR=1.54; 95%CI 1.35 to 1.77) are factors that increase the chance of six-year-old schoolchildren to be active.ConclusionsThe school infrastructure and environment should be seen as strategies to promote physical activity and reduce sedentary behavior in preschool children.
