We provide a wide-ranging review of health-related physical activity in children and adolescents using a behavioural epidemiology framework. In contrast to many other reviews, we highlight issues associated with true sedentary behaviours alongside physically active behaviours. Specifically, we review the evidence concerning the links between physical activity and cardiovascular disease, overweight and obesity, psychosocial measures, type II diabetes, and skeletal health. Although the evidence is unconvincing at times, several factors lead to the conclusion that promoting physical activity in youth is desirable. A review of the prevalence of physical activity and sedentary behaviours shows that many young people are active, but this declines with age. A substantial number are not adequately active for health benefits and current trends in juvenile obesity are a cause for concern. Prevalence data on sedentary behaviours are less extensive but suggest that total media use by young people has not changed greatly in recent years. Most children and adolescents do not exceed recommended daily hours of TV viewing. Physical activity is unrelated to TV viewing. We also identified the key determinants of physical activity in this age group, highlighting demographic, biological, psychological, behavioural, social and environmental determinants. Interventions were considered for school, family and community environments. Finally, policy recommendations are offered for the education, governmental, sport and recreation, health, and mass media sectors. 相似文献

Abstract The academic study of sport and exercise science has expanded greatly into the arena of public health over the past 20 years or more and Europe has played a significant role in this. It is opportune to review evidence concerning ways to change population levels of physical activity for health. This paper summarises such evidence by using a lifespan approach with physical activity behaviour change for children and adolescents, adults and older adults. Correlates of physical activity are identified and the outcome of interventions is discussed. Intervention success has been variable often due to weak fidelity and short-term implementation, and process evaluation is missing from many such studies. Nevertheless, evidence points to possible behaviour change across all age groups and through multiple settings, including schools, worksites and the community. 相似文献

This study examined the effect of health worry (i.e., cognitive aspect of anxiety resulting from concern for health) on walking difficulty in a nationally representative sample (N = 7,527) of older adults (M age = 76.83 years). The study further tested whether physical activity mediates the effect of health worry on walking difficulty in a 6-year follow-up design. Results of a mediation analysis using structural equation modeling showed that people with a high degree of health worry engaged in less physical activity (β = -.24, p < .001), and people who participated in less physical activity were more likely to report walking difficulty at the 6-year follow-up (β = -.22, p < .001). There was a significant indirect effect from health worry to walking difficulty through physical activity (β = .05, p < .001), controlling for demographic, psychosocial, and health related factors. Results suggested that inducing threat and worry may not be effective for physical activity promotion in the older population. More promising coping and regulation strategies are discussed. 相似文献

The objective of this systematic review and meta-analysis was to evaluate the effectiveness of peers to deliver programs or encourage older people to be physically active and improve physical outcomes. Peer reviewed articles published in English between January 1976 and June 2016, retrieved from six databases according to the predefined inclusion criteria were included. Where possible results were pooled and meta-analyses conducted. Eighteen articles were included in the review, a total of 3,492 intervention participants, average age 66.5 years and 67.1% were female. Overall, study quality was medium to high. Interventions mainly included resistance, flexibility and cardiovascular training, however there was one aquatic exercise group. Eight studies were delivered by peers and five utilised peer support, which included advice and being positive but was not directly linked to an exercise intervention. While 16 of the 18 studies reported improvement in levels of physical activity and/or noted physical benefits by peer involvement, the meta-analyses findings supported the control groups for the six-minute-walk-test and the timed-up-and-go test. Findings from this review suggest exercise programs involving peers can promote and maintain adherence to exercise programs. However, results were inconclusive as to whether peers have a positive effect on improving older people’s physical function. 相似文献

It is clear that, despite their natural tendencies, children have become less physically active in recent decades, with children today expending approximately 600 kcal· day -1 less than their counterparts 50 years ago. Although the health consequences of a reduced energy expenditure in adults is well documented, there is little direct evidence linking sedentariness with health in children. However, three main benefits arising from adequate childhood physical activity have been postulated. The first is direct improvements in childhood health status; evidence is accumulating that more active children generally display healthier cardiovascular profiles, are leaner and develop higher peak bone masses than their less active counterparts. Secondly, there is a biological carryover effect into adulthood, whereby improved adult health status results from childhood physical activity. In particular, childhood obesity may be a precursor for a range of adverse health effects in adulthood, while higher bone masses in young people reduce the risk of osteoporosis in old age. Finally, there may be a behavioural carryover into adulthood, whereby active children are more likely to become more active (healthy) adults. However, supporting evidence for this assertion is weak. Given this background, recent health guidelines suggesting that children should accumulate 60 min of moderate-intensity physical activity every day - supplemented by regular activities that promote strength flexibility and bone strength - appear to be justified. Future developments should include the implementation of large-scale, longitudinal studies spanning childhood and young adulthood, the further refinement of tools for measuring physical activity accurately in young people, and research into the relative strength of association between fitness - as well as activity - and health in children. 相似文献

Abstract Physical activity is an integral component of a healthy lifestyle, with relationships documented between physical activity, chronic diseases, and disease risk factors. There is increasing concern that many people are not sufficiently active to benefit their health. Consequently, there is a need to determine the prevalence of physical activity engagement, identify active and inactive segments of the population, and evaluate the effectiveness of interventions. The aim of the present study was to identify and explain a number of methodological and decision-making processes associated with accelerometry, which is the most commonly used objective measure of physical activity in child and adult research. Specifically, this review addresses: (a) pre-data collection decisions, (b) data collection procedures, (c) processing of accelerometer data, and (d) outcome variables in relation to the research questions posed. An appraisal of the literature is provided to help researchers and practitioners begin field-based research, with recommendations offered for best practice. In addition, issues that require further investigation are identified and discussed to inform researchers and practitioners of the surrounding debates. Overall, the review is intended as a starting point for field-based physical activity research using accelerometers and as an introduction to key issues that should be considered and are likely to be encountered at this time. 相似文献

The relationship between physical activity (PA) and cognition has received much attention recently. While evidence of improved cognition following PA has consistently been observed, the majority of studies have spotlighted aerobic exercise and the effects of other modes of PA, such as Tai Ji Quan, on cognition have received limited attention. This article provides a brief review of the literature concerning the influence of Tai Ji Quan on cognition in older adults, including those with intact cognition and those with cognitive impairment. In addition, this review proposes potential mechanisms (cardiovascular fitness, motor fitness, movement coordination, social interaction, and meditation statuses as well brain structure and function) evaluated from a neuroimaging perspective that may explain the Tai Ji Quan–cognition relationship. Finally, we present suggestions for future research. In conclusion, Tai Ji Quan, with its multi-faceted characteristics, shows promise as a mode of PA for enhancing cognition, as well as brain health, in older adults. Based on the findings in this review, further exploration of the effects of Tai Ji Quan on cognition in older adults is warranted. 相似文献

PurposeThe study was to examine county-level associations of physical activity with coronavirus disease 2019 (COVID-19) cases and deaths, per 100,000 county residents.MethodsData were collected from publicly available data sources for 3142 counties and equivalents, including the District of Columbia. Subjective health ratings, percentage uninsured, percentage unemployed, median household income, percentage female residents, percentage White residents, percentage of residents 65 years of age or older, and rural designation served as controls.ResultsThe two-level random intercept regression showed that physical activity rates at the county level were statistically and negatively associated with COVID-19 cases and deaths. Additional analyses showed that physical activity rates moderated the relationship between cases and deaths, such that the relationship was strongest when physical activity rates were low.ConclusionThe results presented here offer empirical evidence of the benefits of county-level physical activity during a pandemic. Implications for public health and physical activity provision are discussed. 相似文献

Despite the significant health benefits of regular physical activity for older adults, only a minority achieve recommended levels. To develop effective interventions, the reasons for the low levels of physical activity in this population must be understood. The present review identifies and synthesizes qualitative studies concerning the acceptability of physical activity to community dwelling older adults. A systematic search of four electronic databases identified 10 studies meeting inclusion criteria. These were appraised, and findings were combined and compared using thematic synthesis. Older adults construed physical activity as a by-product of other activities, rather than as a purposeful activity within itself. This seemed to be linked to their self-perception as an ageing member of society, with physical activity considered irrelevant, and competing roles and responsibilities (e.g., family) taking precedence. Additionally, older adults appeared to experience conflict between maintaining their autonomy and accepting the physical and social vulnerabilities associated with ageing. As older adults do not see physical activity as purposeful within itself, interventions promoting moderate or vigorous physical activity are likely to have limited success. As even small increases in physical activity benefit older adults, future interventions may wish to target the reduction of sedentary behaviour in this population. 相似文献

ABSTRACTEffective and sustainable strategies for physical activity promotion during childhood are of considerable importance to physical education, sport, and health organisations. Multi-component physical activity intervention approaches for children and young people are firmly rooted within the literature; however, there is a dearth of research evidence pertaining to healthy lifestyle promotion within and beyond the school environment. ‘Promoting active lifestyles in schools’ represents a valuable resource for teachers seeking to integrate health-related learning and encourage physically active students. The essential ingredients within this book are the active pedagogies and the health-related learning strategies for children from the ages of 5 to 16 years. Through a consistent formula, this book positions the longitudinal process of health-related learning at the centre of its practice, by providing age-appropriate learning outcomes, activities and assessment strategies within and beyond the school environment. This review seeks to examine the focus of the book and consider its contribution to the existing empirical evidence base within the fields of physical education, health education and physical activity promotion. 相似文献

Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults. 相似文献

Identifying factors related to physical activity levels in young people is important for a more efficient health promotion. The aims of this study were to assess physical activity levels in a national sample of urban Spanish adolescents, and to examine the association between significant others' physical activity (father, mother, brother, sister, and close friends) and that of the adolescents. The present study comprised 2260 adolescents (1157 boys, 1103 girls) aged 13.0-18.5 years participating in the AVENA Study. Both the adolescents' physical activity and that of their relatives and close friends was assessed by questionnaire. The odds of being active were higher in boys than girls (odds ratio?=?2.79, 95% confidence interval?=?2.34-3.33) and tended to decrease across age groups in both boys and girls. Father's and older brother's physical activity was associated with boys' physical activity, while that of any significant other was associated with girls' physical activity. When both parents reported being active, boys had nearly two times higher odds of being active and girls had nearly three times higher odds of being active. The physical activity levels of Spanish adolescents are in line with those previously reported. Physical activity levels in girls are strongly related to the physical activity of any significant other, whereas physical activity levels in boys are only related to their male relatives' physical activity. 相似文献

身体活动指“由骨骼肌产生的体能消耗运动”．是保持身体健康、增进社会交往的重要方式和途径。在澳大利亚，虽然有研究调查民族群体身体活动的各个层面，但总体而言．多数研究更侧重于民族群体的同质性，而忽视了其异质性。本研究探讨在新南威尔士州居住的澳籍香港老年华人对身体活动的概念理解及对身体活动的态度。研究使用开放性问卷进行个体深度访谈，受访者22人。研究发现，大多数受访者不清楚“身体活动”这一术语的含义，对他们来说，“身体活动”是一个模糊的、复杂的术语。该群体对身体活动的态度反映了他们在预防性卫生保健方面的文化和健康观念。显然，提升澳籍香港老年华人的身体活动水平．需要一种基于文化特殊性的健康促进策略以解决对身体活动的误解，同时也需要具体的身体活动态度与华人整体性保健观念相匹配。 相似文献
