ABSTRACT
BACKGROUND: This study aims to verify the association between neck circumference (NC) and metabolic syndrome and establish NC cut-off points to predict metabolic syndrome. METHODS: Weight, height, NC, waist circumference, body mass index, fasting plasma glucose, HDL cholesterol, triglycerides and blood pressure were measured in a cross-sectional and population-based study with 966 adults. The association between NC and the burden of metabolic syndrome disease was evaluated by multinomial logistic regression. Receiver operating characteristic curves were used to acquire gender-specific cut-off values and predict metabolic syndrome. The NC is a simple anthropometric measurement, has low evaluation costs, can estimate the subcutaneous fat in the upper body and is related to cardiometabolic risks. RESULTS: NC is an independent predictor of metabolic syndrome burden with high association to women. The syndrome components stratification indicated that the NC of individuals with one component was lower than those with three or more (P = 0.001). Metabolic syndrome prediction cut-off point was a NC of 39.5 cm for men and 33.3 cm for women. CONCLUSIONS: Increased NC was associated with higher metabolic syndrome risks. This anthropometric parameter can be used as an additional marker for screening cardiovascular risk diseases.

BACKGROUND: It is of great value to develop valid instruments to estimate food consumption; for this purpose, the triads method has been applied in validation studies of dietary intake to evaluate the correlation between three measurements [food frequency questionnaire (FFQ), reference method and biomarker]. The main aim of the present study was to validate a FFQ for Brazilian adults by means of the method of triads by estimating the ingestion of total fatty acids based on the level of saturation. METHODS: The present study enrolled 152 Brazilian adults of both sexes, who were residents in the city of Viçosa, Brazil. The ingestion of total saturated, monounsaturated, polyunsaturated, trans, linoleic and linolenic fatty acids was assessed by means of a FFQ, two food records, and biomarkers, which were detected by gas chromatography. The validation coefficients were calculated using the method of triads and concordance was determined by Kappa statistics. RESULTS: The FFQ was considered an adequate dietary method, because, based on the validation coefficients, it estimates the intake of total fat (0.84), as well as linolenic (0.90) and linoleic acids (0.31). A high concordance rate was confirmed for all nutrients assessed by the FFQ and food records. Regarding the biomarkers, linolenic acid and linoleic acid presented greater concordance. CONCLUSIONS: According to the validation coefficients, the FFQ precisely estimated total fat, linolenic acid and linoleic acid contents.

Objetivo: Descrever a prevalência da utilização de serviços de fisioterapia entre a população adulta urbana de Lages (Santa Catarina) segundo variáveis demográficas e socioeconômicas. Métodos: Realizou-se um estudo transversal de base populacional com amostra obtida em múltiplos estágios e composta por adultos entre 20 e 59 anos (n=2.051). Os dados foram coletados por meio de entrevistas domiciliares em que se obteve a informação por parte dos sujeitos de pesquisa sobre o uso, em algum momento da vida, de serviços de fisioterapia. Foi calculada a prevalência desse desfecho para a população global segundo sexo, idade, escolaridade, autoavaliação em saúde e renda. Resultados: Observou-se que a prevalência da utilização de serviços de fisioterapia foi de 33,5% (IC95% 33,0%-39,8%) entre os homens e de 31,5% (IC95% 28,9%-34,1%) entre as mulheres. Quanto às demais variáveis demográficas investigadas, verificou-se que a prevalência do uso da Fisioterapia aumentou de acordo com a idade dos indivíduos, sendo o maior valor relatado no grupo de 50 a 59 anos (47,2%; IC95% 42,4%-52,0%) e foi maior entre as pessoas que referiram cor amarela (45,9%; IC95% 29,1%-62,7%). Em relação às variáveis socioeconômicas, constatou-se que grupos com melhores indicadores reportaram maior uso do serviço, sendo esse valor equivalente a 46,9% (IC95% 42,3%-51,5%) no estrato de maior renda e a 37,5% (IC95% 34,4%-40,7%) entre aqueles de 12 a 15 anos de estudo. Conclusão: Observou-se, no presente estudo, que o uso de serviços de fisioterapia variou na população de acordo com as características socioeconômicas e demográficas das pessoas investigadas.
Objective: To describe the prevalence of physical therapy service use among the urban adult population of Lages (Santa Catarina), according to demographic and socioeconomic variables. Methods: A population-based cross-sectional study with multiple-stage sampling was carried out among adults aged 20 to 59 years (n=2051). Data were gathered by means of interviews at the participants home, in which they provided information on the use of physical therapy services over their lifetime. The prevalence of this outcome was estimated for the entire population according to sex, age, educational level, self-evaluation of health, and income. Results: The prevalence of physical therapy service use was 33.5% (95% CI: 33.0%-39.8%) among men and 31.5% (95% CI: 28.9%-34.1%) among women. Regarding the other demographic variables investigated, the prevalence of physical therapy use increased with age and was highest among the 50 to 59 year-old group (47.2%; 95% CI: 42.4%-52.0%). The prevalence was also higher among participants of self-reported Asian background (45.9%; 95% CI: 29.1%-62.7%). Regarding socioeconomic variables, it was observed that groups with better indicators reported greater service use: 46.9% (95% CI: 42.3%-51.5%) in the highest income range and 37.5% (95% CI: 34.4%-40.7%) in the range of 12 to 15 years of education. Conclusion: The present study found that physical therapy service use varied among this population according to the participants socioeconomic and demographic characteristics.
