ABSTRACT
The objective was evaluating the psychometric properties of the Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) among Brazilian young adults of both genders. The sample was composed by 506 undergraduate students (295 females and 211 males), aged between 17 and 29 years old. Exploratory and confirmatory factor analyses were used for construct validity (N = 506). Correlations between the SATAQ-3 scores and those of the Tripartite Influence Scale (TIS) and Body Shape Questionnaire (BSQ) were used for convergent validity. Reliability was assessed through internal consistency (α) and reproducibility (test-retest) through comparison of the means obtained at two different time points and through intra-class correlation. The scale presented a factor structure composed of five factors, replicated in the confirmatory factor analysis with satisfactory values for the measurements of adjustment to the model. Correlations with the BSQ and TIS scores were rho = .52 and rho = -.35, respectively. Cronbach's alpha coefficients were satisfactory, and their stability was demonstrated. Brazilian SATAQ-3 had good validity and reproducibility, being indicated for use in samples of Brazilian youths.

BACKGROUND: Increasing age and cholesterol levels, male gender, and family history of early coronary heart disease (CHD) are associated with early onset of CHD in familial hypercholesterolemia (FH). OBJECTIVE: Assess subclinical atherosclerosis by computed tomography coronary angiography (CTCA) and its association with clinical and laboratorial parameters in asymptomatic FH subjects. METHODS: 102 FH subjects (36% male, 45 ± 13 years, LDL-c 280 ± 54 mg/dL) and 35 controls (40% male, 46 ± 12 years, LDL-c 103 ± 18 mg/dL) were submitted to CTCA. Plaques were divided into calcified, mixed and non-calcified; luminal stenosis was characterized as >50% obstruction. RESULTS: FH had a greater atherosclerotic burden represented by higher number of patients with: plaques (48% vs. 14%, p=0.0005), stenosis (19% vs. 3%, p=0.015), segments with plaques (2.05 ± 2.85 vs.0.43 ± 1.33, p=0.0016) and calcium scores (55 ± 129 vs. 38 ± 140, p=0.0028). After multivariate analysis, determinants of plaque presence were increasing age (OR=2.06, for age change of 10 years, CI95%: 1.38-3.07, p<0.001) and total cholesterol (OR=1.86, for cholesterol change by 1 standard deviation, CI95%: 1.09-3.15, p=0.027). Coronary calcium score was associated with the presence of stenosis (OR=1.54; CI95%: 1.27-1.86, p<0.001, for doubling the calcium score). Male gender was directly associated with the presence of non-calcified plaques (OR: 15.45, CI95% 1.72-138.23, p=0.014) and inversely with calcified plaques (OR=0.21, CI95%: 0.05-0.84, p=0.027). Family history of early CHD was associated with the presence of mixed plaques (OR=4.90, CI95%: 1.32-18.21, p=0.018). CONCLUSIONS: Patients with FH had an increased burden of coronary atherosclerosis by CTCA. The burden of atherosclerosis and individual plaque subtypes differed with the presence of other associated risk factors, with age and cholesterol being most important. A coronary calcium score of zero ruled out obstructive disease in this higher risk population.
