Body image in children and adolescents diagnosed with the human immunodeficiency virus: a systematic review

ABSTRACT CONTEXT: The relationship with body image, which is the way the body presents itself to each subject, can be aggravated in children and adolescents diagnosed with an human immunodeficiency virus (HIV) infection, since these patients use antiretroviral therapy and may suffer from the adverse effects of the treatment due to continuous use of medication. OBJECTIVE: To estimate the prevalence of body image dissatisfaction, to describe the assessment methods, and to identify associated factors in children and adolescents diagnosed with HIV. DESIGN AND SETTING: This is a systematic review. Department of Physical Education, Florianópolis - Brazil METHODS: We followed the procedures of the Preferred Reporting Items for Systematic Reviews (PRISMA) and the Cochrane recommendations in the selection of articles through a search performed in eight databases. RESULTS: Prevalence of body image dissatisfaction due to thinness was between 36.7-52.0% in males and 28.1-36.4% in females, and body image dissatisfaction due to overweight was between 8.0-31.2% in males and 21.9-50.0% in females. Factors associated with body image dissatisfaction were as follows: female sex, older age, low levels of physical activity, low self-esteem, higher body fat, higher body weight, greater arm muscle area, triceps skinfold thickness, and higher body mass index. CONCLUSION: Children and adolescents of both sexes diagnosed with HIV infection are dissatisfied by thinness and overweight of their body image.

Association between bone mineral density and content and physical growth parameters among children and adolescents diagnosed with HIV: a cross-sectional study

ABSTRACT BACKGROUND: During childhood and adolescence, there are significant increases in bone mineral content (BMC) and bone mineral density (BMD). OBJECTIVE: To investigate physical growth parameters associated with BMD and BMC among children and adolescents diagnosed with human immunodeficiency virus (HIV). DESIGN AND SETTING: Cross-sectional study conducted in Florianópolis, Brazil, among 63 children and adolescents (aged 8-15 years) diagnosed with HIV. METHOD: BMD, BMC and fat percentage z score were evaluated using dual X-ray absorptiometry. Age/height z score and body mass index (BMI)/age z score were obtained in accordance with international recommendations, and bone age was obtained through hand-wrist radiography. Sex, family income, information on HIV infection (T CD4+ lymphocyte count, viral load and type of antiretroviral therapy, moderate-vigorous physical activity and sedentary behavior) were used as adjustment variables in the analyses. Simple and multiple linear regression analyses were performed, with a significance level of P ≤ 0.05. RESULTS: Subtotal BMD (without the head region) was directly associated with bone age, BMI/age z score and fat percentage z score, even after adjusting for covariates. Subtotal BMC/height was directly associated with bone age, height/age z score, BMI/age z score and fat percentage z score, even after adjusting for covariates. CONCLUSION: Subtotal BMD and subtotal BMC/height were directly associated with physical growth indicators among children and adolescents diagnosed with HIV.

Excesso de adiposidade corporal periférica, central e geral em adolescentes de uma cidade do sul do Brasil / Excess of peripheral, central and general body adiposity in adolescents in a city in southern Brazil

Objetivo: estimar a prevalência e analisar os fatores sociodemográficos e de estilo de vida associados ao excesso de adiposidade periférica, central e geral em adolescentes. Método: estudo transversal, realizado na cidade de São José/Santa Catarina, Brasil, com 1.132 adolescentes (14-19 anos). As variáveis dependentes foram adiposidade periférica (dobra cutânea [DC] do tríceps), central (DC subescapular) e geral (presença de adiposidade periférica e central), classificadas pelo percentil 90 do Centers for Disease Control and Prevention. As variáveis independentes foram nível econômico, atividade física (AF) e hábitos alimentares, obtidos por meio de questionários. A maturação sexual foi avaliada segundo critérios de Tanner. Resultados: o excesso de adiposidade periférica, central e geral, foi de 11,1%, 10,3% e 7,1%, respectivamente, para adolescentes do sexo masculino e, 13,1%,14,7% e 9,8%, respectivamente, para adolescentes do sexo feminino. Os adolescentes do sexo masculino com baixos níveis de AF apresentaram maiores chances de excesso de adiposidade periférica (OR:2,32; IC95%: 1,09-5,37). As adolescentes do sexo feminino, no estágio maturacional pós-púbere apresentaram maiores chances de excesso de adiposidade central (OR:3,80; IC95%:2,25-6,41) e geral (OR:3,31; IC95%:1,79-6,10), e aquelas que estudavam no período noturno apresentaram menores chances de ter excesso de adiposidade central (OR:0,35; IC95%:0,18-0,71) e geral (OR:0,43; IC95%:0,19-0,95). Conclusão: o excesso de adiposidade se fez presente, sendo que o baixo nível de AF para os adolescentes do sexo masculino, o estágio maturacional póspúbere e o turno de estudo diurno foram fatores associados ao excesso de adiposidade para as adolescentes do sexo feminino.

Objective: to estimate the prevalence and to analyze sociodemographic and lifestyle factors associated with excess peripheral, central and general adiposity in adolescents. Method: a cross-sectional study, conducted in the city of São José/Santa Catarina, Brazil, with 1,132 adolescents (14-19 years old). The dependent variables were peripheral adiposity (tríceps skinfold), central (subscapular skinfold) and general (presence of peripheral and central adiposity), classified from the 90th percentile of the Centers for Disease Control and Prevention curve. The independent variables were economic level, physical activity (PA) and eating habits, obtained through questionnaires. The sexual maturation was evaluated according to Tanner criteria. Results: the excess of central and general peripheral adiposity was 11.1%, 10.3% and 7.1%, respectively, for male adolescents and 13.1%, 14.7% and 9.8%, respectively, for adolescent females. Males with low PA l evels presented higher odds of excess peripheral adiposity (OR: 2.32; 95% CI: 1.09-5.37). The female adolescents in the post-pubertal maturational stage presented higher odds of excess central adiposity (OR: 3.80; 95% CI: 2.25-6.41) and general adiposity (OR: 3.31; 95% CI: 1.79-6.10), and those who studied at night had a lower chance of having excess central adiposity (OR: 0.35, 95% CI: 0.18-0.71) and general adiposity (OR: 0.43; 95% CI: 0.19-0.95). Conclusion: the excess of adiposity was present and that the low level of PA for the male adolescents, the post-pubertal maturational stage and the daytime shift were factors associated with excess adiposity for female adolescents.

Aspects to consider in health professionals' promotion of physical activity / Aspectos a serem considerados na promoção de atividade física por profissionais de saúde

In Brazil, bodily practices and physical activity (BPPA) have come a long way, with the implementa-tion of policies, actions and programs that have substantially contributed to public health. However, recent setbacks, in which political instability, scarcity and cuts in public spending predominate, show that more progress and consolidation in the National Health System (SUS) are still needed. Thus, the objective of this article is to demonstrate the aspects that must be considered for promoting BPPA in primary health care, discussing its complexity and multifactorial nature, aimed at health profession-als, especially in physical education. In conclusion, essential aspects were highlighted, ranging from the struggle to defend and advance public policies that encourage the promotion and consolidation of the BPPA, to theories that help understand the dimensions of human behavior

No Brasil, as práticas corporais e atividade física (PCAF) obtiveram avanços com a implementação de políticas, ações e programas que contribuíram substancialmente com a saúde pública. Entretanto, recen-tes retrocessos, em que a instabilidade política, escassez e cortes de gastos públicos predominam, evidenciam o quando as PCAF ainda precisam avançar e serem consolidadas no Sistema Único de Saúde. Assim, o objetivo desse ensaio é demonstrar os aspectos que devem ser considerados para a promoção das PCAF na Atenção Primária à Saúde, trazendo reflexões quanto a sua complexidade e multifatoriedade. Essa reflexão é direcionada aos profissionais de saúde, sobretudo aos profissionais de Educação Física. Em conclusão, foram ressaltados aspectos essenciais, que vão desde a luta pela defesa e avanço de políticas públicas que incentivem o fomento e consolidação das PCAF até a apropriação de teorias que ajudem a compreender a dimensão do comportamento humano
