Item Rotating shift workers with vitamin D defciency have a higher risk of obstructive sleep apnea.(2022) Menezes Júnior, Luiz Antônio Alves de; Fajardo, Virgínia Capistrano; Freitas, Silvia Nascimento de; Coelho, George Luiz Lins Machado; Oliveira, Fernando Luiz Pereira de; Nascimento Neto, Raimundo Marques do; Meireles, Adriana LúciaObjectives The study aimed to evaluate the association between obstructive sleep apnea (OSA) and vitamin D defciency (VDD) in shift workers. Methods This cross-sectional study included male rotating shift workers in an iron ore extraction company. Participants were classified as VDD when 25(OH)D < 20 ng/mL for a healthy population and 25(OH)D < 30 ng/ mL for groups at risk for VDD. Risk of developing OSA was classified by Berlin questionnaire (BQ) and NoSAS score. Data were compared using chi-square analysis with Cramer’s V as effect size, and Bonferroni correction. Multivariate logistic regression analysis was performed to investigate whether or not VDD was associated with OSA risk assessment. Results Among 1423 male workers, mostly younger, aged 30 to 39 years (53%), worked shifts for more than 5 years (76%). The prevalence of high risk of OSA by BQ was 16%, and 33% by NoSAS score. Additionally, 29% had VDD. In multivariate analysis, controlled for confounding factors, workers with VDD had a 52% increased chance of OSA by BQ (OR 1.52; CI95% 1.06–2.18) and a 64% increased chance of OSA by NoSAS score (OR 1.64; CI95% 1.09–2.48). After subgroup analyses, similar results were not observed in workers aged 20–29 and 30–39 years. Conclusion Rotating shift workers with vitamin D defciency are more likely to have obstructive sleep apnea, assessed by the Berlin questionnaire and NoSAS score.Item Hypertension is associated with a variant in the RARRES2 gene in populations of Ouro Preto, Minas Gerais, Brazil : a cross-sectional study.(2021) Batista, Aline Priscila; Barbosa, Keila Furbino; Azevedo, Rafael Júnior de; Vianna, Valeska Natiely; Queiroz, Erica Maria de; Marinho, Carolina Coimbra; Coelho, George Luiz Lins MachadoBackground: Arterial hypertension (AH) is implicated in vascular health and contributes significantly to cardiovascular morbidity and mortality. In addition to the contribution of usual risk factors for AH, elucidating the influence of genetic factors is a promising area of investigation. Therefore, we evaluated the association between AH and cardiovascular risk factors (CVRFs) and genetic polymorphisms in communities in Southeast Brazil. Methods: A total of 515 adults aged 18-91 years, who were cross-sectionally assessed between 2015-2016, were included. Demographic, clinical, behavioral, anthropometric characteristics, and laboratory parameters and 12 single nucleotide polymorphisms in seven candidate genes involved in cardiovascular risk (RARRES2, AGT, NOS3, GNB3, APOE, APOB, APOC3, LDLR, and PPARG) were evaluated, with AH as the outcome. Sex, age, and laboratory parameters were considered the main confounding factors. Results: There was a significant association between age >60 years (odds ratio [OR] =6.74), alcohol dependence (OR=3.84), smoking (OR=1.74), overweight (OR=1.74), high plasma triglyceride (TG) levels (OR=1.98) and low high-density lipoprotein (HDL-c) (OR=6.22), diabetes (OR=3.68), and insulin resistance (OR=2.40) and AH. A significant association was observed between rs4721 in RARRES2 and AH. The T allele in homozygosis was a potent chance modifier for AH. The highest chance gradients for AH were characterized by the presence of the TT genotype and DMT2 (OR=9.70), high TG (OR=6.26), low HDL-c (OR=8.20), and age more than 60 years (OR=9.96). Conclusion: The interaction of the T allele of the rs4721 polymorphism in RARRES2 with CVRFs may predispose carriers to a higher cardiovascular risk.Item Anthropometric measurements and obesity diagnosis in schoolchildren.(2011) Cândido, Ana Paula Carlos; Freitas, Silvia Nascimento de; Coelho, George Luiz Lins MachadoTo evaluate whether anthropometric methods such as arm muscle area, armfat area, Rohrer index, conicity index, and waist-to-height ratio and the commonly usedbody mass index method are suitable for obesity screening in a multiethnic paediatric pop-ulation.Item Association between nutritional status, food habits and physical activity level in schoolchildren.(2012) Coelho, Lorene Gonçalves; Cândido, Ana Paula Carlos; Coelho, George Luiz Lins Machado; Freitas, Silvia Nascimento deObjective: To analyze the relation between nutritional status, food habits and physical activity level in schoolchildren. Methods: A cross-sectional study was carried out with 661 schoolchildren, from 6 to 14 years old, enrolled in public and private schools located in the urban area of Ouro Preto, state of Minas Gerais, Brazil. A semistructured questionnaire was applied to collect data on demographic, socio-economic, anthropometric and level of physical activity variables. Schoolchildren were classified according to criteria for body mass index by age, body fat percentage and physical activity level, respectively. Dietary data were collected through a validated food frequency questionnaire specific for children and adolescents. Food consumption was evaluated according to an adaptation of the Recommended Foods Score, whose objective is the assessment of overall diet quality with a focus on healthy food consumption. Results: We observed high frequency of overweight according to body mass index per age (20.1%) and body fat percentage (22.8%), as well as physical inactivity (80.3%) among schoolchildren. We also found low scores on the Recommended Foods Score in 77.2% of students. There was no significant relation between overweight and physical inactivity or food consumption (p > 0.05). Conclusion: Schoolchildren had a high frequency of overweight, which, alone, was not associated with the high physical inactivity and the low quality diet observed. Therefore, more studies should be performed to identify other factors besides those already described, which may be influencing overweight in this population.Item Anthropometric methods for obesity screening in schoolchildren; the Ouro Preto Study.(CÂNDIDO, A. P. C. et al. Anthropometric methods for obesity screening in schoolchildren; the Ouro Preto Study. Nutrición Hospitalaria, v. 27, p. 145-152, 2012. Disponível em: . Acesso em: 01 set. 2014., 2012) Cândido, Ana Paula Carlos; Alosta, Juliana Pereira Sallum; Oliveira, Cinthia Teixeira de; Freitas, Renata Nascimento de; Freitas, Silvia Nascimento de; Coelho, George Luiz Lins MachadoBackground and aims: Childhood obesity is increasing dramatically in last decades. To evaluate the usefulness of body mass index (BMI), skinfold thickness (ST), waist circumference (WC), and foot-to-foot bioelectrical impe - dance (BIA-FF) for screening for obesity in mixed-race population, using the tetrapolar bioelectrical impedance (BIA-T) technique as reference method. Methods and results: A cross-sectional-based population study was performed in the city of Ouro Preto, Brazil, in 2006. Schoolchildren aged 6-15 years (n = 788) was randomly selected according to age and sex stratified by the proportion of students in each schools of the city. Nonparametric receiver operating characteristic (ROC) analysis was used to define the sensitivity and specificity for each method studied using the tetrapolar method as reference. The BMI and the BIA-FF were the most suita - ble for adiposity screening in pre-pubertal and pubertal stages because they present a better balance between sensitivity and specificity, and smaller misclassification. For post-pubertal boys, the BF-ST-D was the best body fat assessment method. Conclusion: The results suggest that BIA-FF and BMI are choice methods for obesity screening in mixed population and that the method choice for body fat screening must be done according to sexual maturity of boys and girls. The present study demonstrates the need to perform studies in wider mixed-race population to determine anthropometric parameters and to examine the predictive ability of methods and cut-offs here elucidated in the development of obesity.
