Factors Correlated with Body Image Dissatisfaction in Children and Adolescents Diagnosed with HIV: A Cross-Sectional Study.

(1) Background: The adverse effects of continuous use of antiretroviral therapy can generate dissatisfaction with body image in children and adolescents diagnosed with Human Immunodeficiency Virus infection (HIV) infection. The aim of this study was to verify the prevalence and factors associated with body image dissatisfaction (BI) in children and adolescents diagnosed with HIV infection; (2) This is a cross-sectional study with 60 children and adolescents (32 females; 28 males) aged 8-15 years diagnosed with HIV, carried out in Florianópolis, Brazil. Information on BI was collected through a silhouette scale, as well as sociodemographic information, biological maturation, lifestyle, self-esteem, adherence to antiretroviral treatment and aspects of HIV infection; (3) Results: The results indicated that 53.

Anthropometric measures associated with fat mass estimation in children and adolescents with HIV.

To verify the association between anthropometric indicators and body fat percentage estimated by dual X-ray absorptiometry (DXA) and air displacement plethysmography (ADP) in children and adolescents diagnosed with human immunodeficiency virus (HIV). This cross-sectional study was carried out with 62 children and adolescents with HIV (aged 8 to 15 years). Body fat percentage was estimated by DXA and ADP.

The Oporto mixed-longitudinal growth, health and performance study. Design, methods and baseline results.

Background: Studies concerning child and adolescent growth, development, performance and health aimed at the multiple interactions amongst this complex set of variables are not common in the Portuguese speaking countries.

Aim: The aim of this paper is to address the key ideas, methodology and design of the Oporto Growth, Health and Performance Study (OGHPS).

Subjects And Methods: The OGHPS is a multidisciplinary mixed-longitudinal study whose main purpose is to examine the multiple interactions among biological, environmental and lifestyle indicators that affect growth, development, health and performance of Portuguese adolescents aged 10-18 years old.

Sex-specific genetic effects in physical activity: results from a quantitative genetic analysis.

Background: The objective of this study is to present a model to estimate sex-specific genetic effects on physical activity (PA) levels and sedentary behaviour (SB) using three generation families.

Methods: The sample consisted of 100 families covering three generations from Portugal. PA and SB were assessed via the International Physical Activity Questionnaire short form (IPAQ-SF).

Genotype by sex and genotype by age interactions with sedentary behavior: the Portuguese Healthy Family Study.

Sedentary behavior (SB) expression and its underlying causal factors have been progressively studied, as it is a major determinant of decreased health quality. In the present study we applied Genotype x Age (GxAge) and Genotype x Sex (GxSex) interaction methods to determine if the phenotypic expression of different SB traits is influenced by an interaction between genetic architecture and both age and sex. A total of 1345 subjects, comprising 249 fathers, 327 mothers, 334 sons and 325 daughters, from 339 families of The Portuguese Healthy Family Study were included in the analysis.

Genotype by energy expenditure interaction with metabolic syndrome traits: the Portuguese healthy family study.

Moderate-to-high levels of physical activity are established as preventive factors in metabolic syndrome development. However, there is variability in the phenotypic expression of metabolic syndrome under distinct physical activity conditions. In the present study we applied a Genotype X Environment interaction method to examine the presence of GxEE interaction in the phenotypic expression of metabolic syndrome.

Clustering of body composition, blood pressure and physical activity in Portuguese families.

Aim: The purposes of this study were: (i) to identify familial resemblances in body fat, blood pressure (BP) and total physical activity (TPA); (ii) to estimate the magnitude of their genetic and environmental influences; and (iii) to investigate shared familial aggregation among these phenotypes.

Subjects And Methods: The sample comprised 260 nuclear families from Portugal. Body fat was assessed by bioelectrical impedance.

Motor coordination, activity, and fitness at 6 years of age relative to activity and fitness at 10 years of age.

Background: Health benefits of physical activity (PA) and physical fitness (PF) are reasonably well established, but tracking studies of PA and PF in childhood have not ordinarily considered the role of motor coordination.

Objectives: To compare the growth status, gross motor coordination (GMC), PA, and PF characteristics of children at 6 years of age relative to aerobic fitness (fit, unfit) and PA (active, sedentary) at 10 years.

Methods: 285 primary school children (142 girls, 143 boys) resident on the 4 main Azorean islands, Portugal, were measured annually (in the fall) from 6 to 10 years.

RT-PCR based analysis of cell culture negative stools samples from poliomyelitis suspected cases.

Background: Routine diagnosis of acute flaccid paralysis (AFP) is still based on classical virological procedures. Several serotypes of enterovirus which possess the potential to cause neurological disorders are not easily isolated in the cell culture systems used for the AFP diagnosis.

Objectives: Our goal was to look into the presence of enterovirus genomes in fecal suspensions previously considered negative by cell culture procedures, using RT-PCR.
