Objectives: To assess the reproducibility and validity a 127-item, habitual intake, foodfrequency questionnaire (FFQ), developed for low-income and low-literacy Brazilian workers, by comparison with a 24-hour dietary recall (24-HDR). Design: The FFQ and 24-HDR were interviewer-administered at the local workplace to each subject twice, with a period of 6 months between estimates; and four 24-HDRs were conducted during the 4-month period between the two FFQs (FFQ1 and FFQ2). Reproducibility was tested by comparing mean nutrient intakes from the two FFQs. Validity was determined by comparing the mean nutrient intakes from the FFQs with the corresponding averages of the six 24-HDRs (reference method). Setting: Goiânia City, in Central West Brazil. Subjects: The study was based on 104 (62 women and 42 men) subjects, aged 18 to 60 years, who were randomly selected. Results: Dietary intake from the FFQ was higher than from the 24-HDR. Reproducibility was assessed by Pearson correlation coefficients for nutrients from FFQ1 and FFQ2, and ranged from 0.23 for retinol to 0.69 for total energy (mean 0.52). Intra-class coefficients for nutrients averaged by the 24-HDRs ranged from 0.29 for vitamin C to 0.76 for total energy; retinol was not significant. In the validation study, correlation between the FFQ and the 24-HDR ranged between 0.21 for vitamin C and 0.70 for total energy (mean 0.50). Adjusting for total energy lowered the coefficients, except for calcium, retinol and vitamin C. Coefficients increased with attenuation, ranging from 0.35 for carbohydrate to 0.65 for calcium. Conclusions: Results indicate that this questionnaire had satisfactory reproducibility and reasonable validity.
Objective: Verify the association between anthropometric indicators and the Subjective Global Assessment of Nutritional Status (SGA) and the Screening of Risk for Nutritional Status and Growth (STRONGkids) scales. Methods: A cross-sectional study with patients from 0 to 18 years admitted in the Hospital das Clínicas, Goiânia (GO), between August and November 2015. Children and adolescents admitted in up to 48 hours were included. Patients who required specific instruments for assessing their nutritional status and those hospitalized in Intensive Care were excluded. Identification and anthropometric data was collected and applied to the SGA and STRONGkids. We performed an analysis comparing proportions and did an agreement assessment, where p<0.05 was significant.Results: 71 patients were evaluated, of whom 9.6% had low or very low birth weight/age, 9.7% had thinness or accentuated thinness according to the weight/height index, 16.9% had a height impairment, 7% were thin according to the body mass index/age, and 32.4% were malnourished with regard to arm muscle circumference. The STRONGkids detected that 69% of the sample had a moderate or high nutritional risk. According to the SGA, malnutrition prevalence was 38.1%. There was an association between the SGA and body mass index/age (p=0.022), height/age (p<0.001) and arm muscle circumference (p=0.014). There was no association between the STRONGkids and anthropometric indicators. A correlation was found between: high nutritional risk versus severe malnutrition and low nutritional risk x the well-nourished (p<0.001), but the agreement was weak (k=0.255). Conclusions: It is recommended to use the STRONGkids as a screening instrument because it has a higher sensitivity for diagnosing patients with a nutritional risk. The SGA should be applied to nutritional assessment due to its association with anthropometry.
BackgroundThe assessment of nutritional status in clinical practice must be done with
simple, reliable, low cost and easy performance methods. The power of handshake is
recognized as a useful tool to evaluate muscle strength, and therefore, it is
suggested that can detect malnutrition.AimTo evaluate the nutritional status by subjective global assessment and power of
handshake preoperatively in patients going to gastrointestinal surgeries and to
compare the diagnosis obtained by subjective global assessment with traditional
anthropometric methods and power of handshake.MethodsA cross-sectional study was conducted with patients for surgery in the
gastrointestinal tract and related organs. Socioeconomic and anthropometric data,
applied to subjective global assessment and checked the power of handshake, were
collected. The force was obtained by the average of three measurements of the
dominant and non-dominant hand and thus compared with reference values of the
population by sex and age, for the classification of nutritional risk.ResultsThe sample consisted of 40 patients, 24-83 years, and most women (52.5%)
housewives (37,5%) and diagnosed with cancer (45%). According to subjective global
assessment, 37.5% were classified as moderately malnourished; 15% were underweight
by BMI measurements; 25% had arm circumference at risk for malnutrition
