Atividade física: prevalência, fatores relacionados e associação entre pais e filhos

Sports participation among Brazilian adolescents and children: systematic review

Abstract The aim of this study is to describe the prevalence of sports participation in Brazilian children and adolescents through a systematic literature review. A search was carried out in the following electronic databases: MEDLINE, WEB OF SCIENCE, BIREME, SCIELO, and SCOPUS for manuscripts published until 2020, combining the keywords: “children”, “adolescents”, “prevalence”, and “sports participation”, in Portuguese and English. Twenty-six articles published between 2003 and 2020 were included in the review, with the aim of estimating the prevalence of participation in organized sports in Brazilian children and adolescents. Considering the regions where the studies were carried out, the majority were developed in the south (57.7%; n=15), followed by the southeast (19.2%; n=05), and northeast (15.4%; n=04), in addition to 7.7% (n=02) in all regions of the country. The data showed prevalence of sports participation ranging from 15.0% to 73.2% (mean of 44.8%) among children and adolescents, being higher in males (63.1%). From the results found, the need to develop public policies is evident, in order to favor adherence and maintenance of young people to sports practice, especially among those of the female sex.

Association of parent-child physical activity: a review update of Brazilian studies – Report Card Brazil

Abstract This systematic review update aimed to search for new evidences about parent-child physical activity among Brazilian studies. A new literature search for Brazilian studies published until 31 December 2019 was performed in the databases Medline, Embase, Cinahl, Lilacs, Sport Discus, and SciELO by the combination of descriptors regarding children and adolescents, physical activity, and parental support, restricted to English and Portuguese language. As result, only one new study were included besides those from previous review which corroborated with previous findings about positive relationship of parent-child physical activity. The included studies (n=14) were presented according to geographical distribution, year of publication, research design and physical activity assessment method. Limitations and future directions about specific physical activity domains and weekly amount, as well as peers and environmental support were highlighted. This review findings reinforced that parental lifestyle behavior is an important factor for active lifestyle promotion among Brazilian children and adolescents.

Gênero e cultura corporal de movimento: práticas e percepções de meninas e meninos

Resumo: Este artigo apresenta os resultados e as análises de uma pesquisa com meninas e meninos dos 8os e 9os anos do ensino fundamental da região metropolitana de uma cidade brasileira. Identificaram-se suas percepções sobre as experiências com as atividades físicas e esportivas, a frequência com que as praticam dentro e fora da escola, seus interesses em relação a elas e suas percepções a respeito do prazer pela prática, da competência corporal e do apoio social. A investigação aplicou questionários fechados aos estudantes, e a amostra final contou com 1742 sujeitos, provenientes de 39 escolas. O gênero mostrou-se um marcador de diferença estatisticamente significativo nos resultados: as desigualdades de gênero foram favoráveis aos meninos em quase todos os aspectos avaliados, exceto no apoio docente, que foi percebido de forma equânime.

[Anthropometric indices to identify metabolic syndrome and hypertriglyceridemic waist phenotype: a comparison between the three stages of adolescence]

OBJECTIVE:

To determine the prevalence of metabolic syndrome (MS) and the hypertriglyceridemic waist phenotype (HW) in a representative adolescent sample; as well as to establish which anthropometric indicator better identifies MS and HW, according to gender and adolescent age.

METHODS:

This cross sectional study had the participation of 800 adolescents (414 girls) from 10-19 years old. Anthropometric indicators (body mass index, waist perimeter, waist/stature ratio, waist/hip ratio, and central/peripheral skinfolds) were determined by standard protocols. For diagnosis of MS, the criteria proposed by de Ferranti et al. (2004) were used. HW was defined by the simultaneous presence of increased waist perimeter (>75th percentile for age and sex) and high triglycerides (>100 mg/dL). The ability of anthropometric indicators was evaluated by Receiver Operating Characteristic curve.

RESULTS:

The prevalence of MS was identical to HW (6.4%), without differences between genders and the adolescence phases. The waist perimeter showed higher area under the curve for the diagnosis of MS, except for boys with 17-19 years old, for whom the waist/stature ratio exhibited better performance. For diagnosing HW, waist perimeter also showed higher area under the curve, except for boys in initial and final phases, in which the waist/stature ratio obtained larger area under the curve. The central/peripheral skinfolds had the lowest area under the curve for the presence of both MS and HW phenotype.

CONCLUSIONS:

The waist perimeter and the waist/stature showed a better performance to identify MS and HW in both genders and in all three phases of adolescence.
