Environmental influences on children\u27s physical activity in early childhood education and care

Background: To examine the relationship between attributes of early childhood education and care (ECEC) settings and children\u27s physical activity and sedentary behavior. Methods: Cross-sectional study involving 490 children aged 2-5 years from 11 ECECs. The ECEC routine, size of the outdoor environment, and time spent in the outdoor environment were calculated for each center. Children\u27s physical activity and sedentary time were measured using accelerometers. Multivariate linear regressions were used to examine associations of the attributes of ECEC centers with the outcome variables, adjusting for the effects of center clustering and gender. Results: Children in ECECs that offered free routines (where children can move freely between indoor and outdoor environments) had lower levels of sedentary time (28.27 min/h vs 33.15 min/h; P = .001) and spent more time in total physical activity (7.99 min/h vs 6.57 min/h; P = .008) and moderate- to vigorous-intensity physical activity (9.49 min/h vs 7.31 min/h; P = .008). Children in ECECs with an outdoor environment \u3e400 m2 had less sedentary time (28.94 min/h vs 32.42 min/h; P = .012) than those with areas children

Measuring unmet need for contraception among women in rural areas of Papua New Guinea

Located in the South West Pacific region, with a population of 7.5 million, Papua New Guinea (PNG) is among a group of Pacific countries with sub-optimal health status. The maternal mortality ratio is 171 per 100,000 live births. Unmet need for contraception and family planning services, although poorly understood in PNG, may be one of the underlying causes of poor maternal health. This study set out to measure the prevalence and trends in unmet need for contraception and the identified socioeconomic factors associated with contraceptive use among women of reproductive age (15–49 years) in PNG. Data available from the Integrated Health and Demographic Surveillance System (IHDSS) were used in this study. A sub-population data set was extracted of 1434 women who gave birth in the preceding two years and resided in four rural surveillance sites: Asaro, Hides, Hiri and Karkar. Analyzes of unmet need for contraception were performed with respect to birth spacing and limiting the number of births. Unmet need for contraception was 34% for the previous birth, 37% for the current pregnancy, and 49% for future family planning. The total unmet need for contraception was 35%, of which 49% was for spacing births and 51% for limiting births. Women's age, education and household wealth are the most significant determinants of unmet need for contraception. The high level of unmet need for contraception may contribute to women's poor health status in PNG. Urgent programming responses from the health sector for supporting effective interventions to increase availability and use of contraceptives are required.

Correlates of sedentary behaviours in preschool children: a review

Background: Sedentary behaviour has been linked with a number of health outcomes. Preschool-aged children spend significant proportions of their day engaged in sedentary behaviours. Research into the correlates of sedentary behaviours in the preschool population is an emerging field, with most research being published since 2002. Reviews on correlates of sedentary behaviours which include preschool children have previously been published; however, none have reported results specific to the preschool population. This paper reviews articles reporting on correlates of sedentary behaviour in preschool children published between 1993 and 2009.Methods: A literature search was undertaken to identify articles which examined correlates of sedentary behaviours in preschool children. Articles were retrieved and evaluated in 2008 and 2009.Results: Twenty-nine studies were identified which met the inclusion criteria. From those studies, 63 potential correlates were identified. Television viewing was the most commonly examined sedentary behaviour. Findings from the review suggest that child&rsquo;s sex was not associated with television viewing and had an indeterminate association with sedentary behaviour as measured by accelerometry. Age, body mass index, parental education and race had an indeterminate association with television viewing, and outdoor playtime had no association with television viewing. The remaining 57 potential correlates had been investigated too infrequently to be able to draw robust conclusions about associations.Conclusions: The correlates of preschool children&rsquo;s sedentary behaviours are multi-dimensional and not well established. Further research is required to provide a more comprehensive understanding of the influences on preschool children&rsquo;s sedentary behaviours to better inform the development of interventions.<br /

Appropriateness of the definition of 'sedentary' in young children : whole-room calorimetry study

The present study aimed to measure the energy cost of three common sedentary activities in young children to test whether energy expended was consistent with the recent consensus definition of 'sedentary' as 'any behaviour conducted in a sitting or reclining posture and with an energy cost ≤1.5 metabolic equivalents (METs)' (Sedentary Behaviour Research Network, 2012).  This was an observational study

Preschool and childcare center characteristics associated with children\u27s physical activity during care hours: an observational study

Background: Preschools and childcare settings offer opportunities to promote adequate levels of physical activity. Research is needed to identify the key features of these settings to optimize young children\u27s activity. The aims of this study were to determine if differences existed in preschool children\u27s physical activity during care hours compared with outside care hours and to examine a comprehensive range of potential center-based correlates of physical activity for preschool boys and girls. Methods: Data are from the Healthy Active Preschool and Primary Years study: 71 childcare centers, 65 preschools and 1002 preschool children. Percent of time in total (light- to vigorous-intensity) physical activity was measured using Actigraph GT1M accelerometers. Center physical environment characteristics, policies and practices were assessed by trained research staff using comprehensive audit tools. Data were collected in 2008/9 and were analyzed separately for boys and girls in Stata using multilevel mixed effects models. Results: Boys and girls were less active during care than outside care hours (51.1 % vs. 52.4 %, p = 0.01; 48.0 % vs. 51.5 %, p \u3c 0.0001, respectively). In the final adjusted models, number of outdoor spaces with natural ground coverings was associated with boys\u27 physical activity (coeff = 0.477, 95 % CI 0.089, 0.867) and the amount of time girls spent indoors before going outdoors was inversely associated with their physical activity (coeff = −0.035, 95 % CI −0.065, −0.004). The models explained 12 and 10 % of boys\u27 and girls\u27 physical activity during care hours, respectively. Conclusions: This study identified that children are significantly less active during than outside care hours. Few center-based correlates of preschool children\u27s physical activity were identified. Future research should explore other aspects of centers, such as what children actually do while they are outside, and broader potential influences on children\u27s behaviours including social, cultural and policy contexts within which centers operat

Influences on consumption of soft drinks and fast foods in adolescents

Soft drink and fast food are energy dense foodstuffs that are heavily marketed to adolescents, and are likely to be important in terms of risk of obesity. This study sought to examine the influences on soft drink and fast food consumption among adolescents as part of a cross-sectional survey of 2,719 adolescents (aged 11-16) from 93 randomly selected schools in New South Wales, Australia. Students provided information on soft drink and fast food consumption, and responded to statements examining influences over consumption. Over half of the boys and more than one third of the girls reported drinking soft drink daily, and consumption peaked in Grade 8 students. A quarter of students reported choosing soft drinks instead of water or milk, and around 40% agreed that soft drink was usually available in their homes. Availability in the home and drinking soft drinks with meals was most strongly associated with consumption in all age groups. Fast food consumption was higher among boys than girls in all age groups. Convenience and value for money yielded the strongest associations with fast foodconsumption in boys, while preferring fast food to meals at home and preferring to &ldquo;upsize&rdquo; meals were most strongly associated with consumption in girls. Interventions to reduce consumption of soft drinks should target availability in both the home and school environment by removing soft drinks and replacing them with more nutritive beverages. Fast food outlets should be encouraged to provide a greater range of healthy and competitively priced options in reasonable portions.<br /

Physical activity during school recess : a systematic review

Context: Interest has increased in examining the physical activity levels of young people during school recess. Identifying correlates of their recess physical activity behaviors is timely, and would inform school-based physical activity programming and intervention development. The review examined the correlates of children\u27s and adolescent\u27s physical activity during school recess periods. Evidence acquisition: Asystematicsearchofsixelectronicdatabases,referencelists,andpersonal archives identified 53 studies (47 focused on children) published between January 1990 and April 2011 that met the inclusion criteria. Data were analyzed in 2011. Correlates were categorized using the social-ecological framework. Evidence synthesis: Forty-four variables were identified across the four levels of the social- ecological framework, although few correlates were studied repeatedly at each level. Positive associ- ations were found of overall facility provision, unfixed equipment, and perceived encouragement with recess physical activity. Results revealed that boys were more active than girls. Conclusions: Providing access to school facilities, providing unfixed equipment, and identifying ways to promote encouragement for physical activity have the potential to inform strategies to increase physical activity levels during recess periods

Relationship between children\u27s physical activity, sedentary behavior, and childcare environments: A cross sectional study

The purpose of this study was to investigate the relationship between the childcare environment and physical activity and sedentary behavior of toddlers and preschoolers. A total of 68 toddlers (1.0–2.9 years) and 233 preschoolers (3.0–5.9 years) were recruited from 11 childcare services in 2013 within the Illawarra and Shoalhaven region of NSW, Australia. For this study analysis was conducted in 2016. The childcare environmentwas assessed using the Environment and Policy Assessment Observation (EPAO) instrument, and childcare services categorized as low, medium, or high based on their scores. Time spent in physical activity and sitting was assessed over one week using activPAL accelerometers. Relationship between EPAO and children\u27s physical activity and sedentary behavior was assessed using multilevel mixed-effects linear regression. Toddlers who attended high EPAO services sat more (8.73 min [−10.26, 27.73]) and stood less (−13.64 min [−29.27, 2.00]) than those who attended low EPAO services. Preschoolers who attended high EPAO services sat less than those in low and medium services (mean [95%CI] = −7.81 min [−26.64, 11.02]). Sub-categories of the EPAO that were associated with less time sitting were: sedentary environments for toddlers and portable play equipment for preschoolers. This study extends previous research by identifying differences between toddlers and preschooler\u27s physical activity and sedentary behaviors in relation to childcare environments. A greater understanding of how the childcare environment relates to sitting time for both toddlers and preschool aged children is needed
