“…In our review of these studies, we found, like others, 48 that most cross-sectional studies reported that overweight children had lower PALs than their non-overweight peers. [49][50][51][52] Some of these studies include objective measures of physical activity, such as accelerometer data.…”

“…In an early report based on 1 y of follow-up during the preschool years, changes in adiposity were smaller with higher levels of activity; 35 the 8-y follow-up results were extended, and the outcomes expanded to include BMI, 48 with results consistent with the earlier report. Among Native American second-grade children in the Pathways Project, activity based on accelerometry was associated with lower adiposity among children of normal weight status, but with higher adiposity and BMI among overweight children.…”

“…Only five of the studies used objective measures of physical activity. 35,48,[65][66][67] The others relied on self-reported measures, either by the children themselves, 61,[68][69][70][71] by their parents, [72][73][74][75][76][77] or by a combination thereof. 78 In the Framingham Children's Study, children wore accelerometers for up to 5 days twice per year.…”

AIM:To review the published prospective observational studies of the relationship of physical activity and sedentary behavior with the development of overweight and adiposity, with an emphasis on methodologic issues. METHODS: Sample size, population studied, length of follow-up, assessment of exposure (physical activity, inactivity, or sedentary behavior), assessment of outcome (relative weight, overweight, % body fatness, adiposity), statistical approach, and main findings were extracted, summarized, and key methodological issues highlighted. RESULTS: In total, 17 studies of physical activity and 15 studies of inactivity/sedentary behavior were identified; as these were not mutually exclusive, 20 unique studies were reviewed. Results were mixed, with most studies showing an inverse association of physical activity with weight or fatness outcomes and/or a direct association of inactivity/sedentary behavior with weight or fatness outcomes. The effects identified were generally of small magnitude. Imprecise measurement of activity exposures likely weakens the observed relationships. Most studies used a pre-post design and had limited duration of follow-up (r2 y). Studies with longer and more frequent follow-up did not always use the most advantageous statistical approach. CONCLUSIONS: On balance, the available evidence from prospective observational studies suggests that increased physical activity and decreased sedentary behavior are protective against relative weight and fatness gains over childhood and adolescence. In addition to improved measurement methods, longer and more frequent follow-up as well as truly longitudinal analysis methods would help establish these important prevention and intervention targets, and identify subgroups or development periods where interventions would likely be effective.

Interventions to prevent obesity in children and adolescents: a systematic literature review

Objective: Preventive measures to contain the epidemic of obesity have become a major focus of attention. This report reviews the scientific evidence for medical interventions aimed at preventing obesity during childhood and adolescence. Design: A systematic literature review involving selection of primary research and other systematic reviews. Articles published until 2004 were added to an earlier (2002) review by the Swedish Council on Technology Assessment in Health Care. Methods: Inclusion criteria required controlled studies with follow-up of at least 12 months and results measured as body mass index, skinfold thickness or the percentage of overweight/obesity. Children could be recruited from normal or high-risk populations.Results: Combining the new data with the previous review resulted in an evaluation of 24 studies involving 25 896 children. Of these, eight reported that prevention had a statistically significant positive effect on obesity, 16 reported neutral results and none reported a negative result (sign test; P ¼ 0.0078). Adding the studies included in five other systematic reviews yielded, in total, 15 studies with positive, 24 with neutral and none with negative results. Thus, 41% of the studies, including 40% of the 33 852 children studied, showed a positive effect from prevention. These results are unlikely to be a random chance phenomenon (P ¼ 0.000061). Conclusion: Evidence shows that it is possible to prevent obesity in children and adolescents through limited, school-based programs that combine the promotion of healthy dietary habits and physical activity.

-Physical activity (PA) in children has a decisive role in motor development and prevention of childhood obesity. The available evidence suggests that there is high prevalence of low levels of PA in children, but little is known about the level of PA in preschool children. The objective of this study was to identify the prevalence and the factors associated with low levels of PA in preschool children. This was a cross-sectional study performed in private schools in the municipality of Olinda (state of Pernambuco), with data collection through parent's face-to-face interviews. The study included 265 children (54.3% girls) with mean age of 4.9 years (SD=0.8). Children who did not perform at least 60 minutes/day of outdoors physical activities were considered exposed to low levels of PA. Data analysis was performed by logistic regression considering low level of PA as the outcome. The results showed that 65.3% (95%CI: 9.4-70.8) of children were classified as exposed to 'low level of PA' . Analysis showed that higher parental education (OR=2.41; 95%CI: 1.13-5.10), lack of space for playing at home (OR=2.36; 95%CI: 1.17-4.78), and attending school in the afternoon (OR=2.92, 95%CI 1.55-5.49) or full-time (OR=57.1, 95%CI 6.57-496.2) were associated with low levels of PA. Preschoolers from families with higher number of children had lower likelihood of low level of PA (OR=0.49; 95%CI 0.26-0.93). It can be concluded that the proportion of children exposed to low levels of PA is high compared to the results of similar studies and that parental and environmental factors are associated with physical activity level in preschool-aged children. Key words: Epidemiology; Motor activity; Preschool. 65,3% (IC95%: 9,8) (OR=2,41; IC95%: 1,10), falta de espaços para jogos e brincadeiras na residência (OR=2,36; IC95%: 1,78) e estudar em período vespertino (OR=2,92; IC95%: 1,49) ou integral (OR=57,1; IC95%: 6,2) foram fatores associados a baixo nível de AF.

Evidências disponíveis sugerem que há elevada prevalência de baixos níveis de AF em crianças, mas pouco se conhece sobre o nível de AF em pré-escolares. O objetivo do estudo foi identificar a prevalência e os fatores associados ao baixo nível de AF em pré-escolares. Estudo transversal realizado em escolas privadas da Cidade de Olinda (PE), com coleta de dados mediante entrevista "face a face" com os pais das crianças. Participaram do estudo 265 crianças (54,3% meninas) com idade média de 4,9 anos (DP=0,8). Foram consideradas expostas a baixo nível de AF as crianças que não realizavam, no mínimo, 60 minutos/dia de AF ao ar livre. A análise dos dados foi efetuada mediante regressão logística, considerando o baixo nível de AF como desfecho. Os resultados mostram que
