title: Identification of food intake patterns and associated factors in teenagers

description: OBJECTIVE: To identify schoolchildren"s dietary patterns and investigate the demographic, social, and economic determinants of the differences found between patterns. METHODS: The sample consisted of 1,330 students aged 11 to 17 years attending the public schools of Salvador, Bahia, Brazil. The subjects' food intake data were collected by a semiquantitative Food Frequency Questionnaire comprising 97 food items. All information was collected during a single interview. The exposure variables were gender, age, and socioeconomic class, and the outcome variables were categorized food consumption pattern in "mixed pattern", "traditional pattern", and "healthy pattern". The data were treated by simple and multiple linear regression analyses and the dietary patterns determined by factor analysis. RESULTS: Most participants were female (56.9%) and over 13 years old (79.2%). The "mixed pattern" was positively associated with females (β=0.181, p&lt;0.001). The "traditional pattern" was negatively associated with classes D, C, and B (β=-0.149, p&lt;0.007), and the "healthy pattern" was negatively associated with females (β=-0.200, p&gt;0.0001) and classes D, C, and B (β=-0.125, p&lt;0.023). CONCLUSION: Three dietary patterns were identified among the adolescents, namely mixed, traditional, and healthy. Gender and socioeconomic class were associated with dietary patterns. Male teenagers and those in the lower socioeconomic classes had a healthier dietary pattern than their peers of higher socioeconomic classes and females.

title: Neck circumference as predictor of excess body fat and cardiovascular risk factors in adolescents

description: OBJECTIVE:To verify whether neck circumference can predict cardiovascular risk factors and excess body fat in adolescents.METHODS:This cross-sectional study included male and female adolescents aged 10 to 14 years from Viçosa, Minas Gerais. The following data were collected: anthropometric measurements, blood pressure, percentage of body fat according to dual energy X-ray absorptiometry, and levels of fasting glucose, fasting insulin, triglycerides, total cholesterol, high-density lipoprotein, and low-density lipoprotein. The anthropometric measurements were used for calculating indices and assessing nutritional status. The receiver operating characteristic curve tested whether neck circumference could predict cardiovascular risk. We also investigated how neck circumference related to the study parameters. The significance level was set at 5% (p&lt;0.05).RESULTS:A total of 260 adolescents were assessed of which 50.4% (n=131) were females, 20.4% (n=53) had excess body weight according to the body mass index-for-age index, and 42.7% (n=111) had excess body fat. Blood pressure (3.9%, n=10) and all biochemical parameters were affected, varying from 1.9% (n=5) for glucose to 65% (n=169) for total cholesterol. Neck circumference correlated with body fat, waist circumference, hip circumference, weight, height, body mass index, waist-to-height ratio, homeostasis model of assessment - insulin resistance, fasting insulin, blood pressure, and high-density lipoprotein (&lt;0.05). It predicted excess body fat and changes in fasting insulin and blood pressure in both sexes, blood glucose and high-density lipoprotein in females, and triglycerides in males (area under the curve &gt;0.5; p&lt;0.05, varying from 0.610 for high-density lipoprotein to 0.817 for blood pressure).CONCLUSION:Neck circumference was capable of predicting excess fat and cardiovascular risk factors in adolescents.

title: Iron intake and its association with iron-deficiency anemia in agricultural workers' families from the Zona da Mata of Pernambuco, Brazil

description: OBJECTIVE:To verify the association between dietary iron intake and the occurrence of iron-deficiency anemia in agricultural workers' families from the municipality of Gameleira in the state of Pernambuco, Brazil.METHODS:The study population consisted of 46 harvesters' families, consisting of 225 individuals. The food intake of each individual was recorded on three different days by directly weighing the foods consumed. Hemoglobin was determined by fingerstick (HemoCue). This research used the probability of adequacy method to assess iron intake and the paired ttest for comparing groups. The Spearman Mann-Whitney test estimated associations between the dietary variables and anemia.RESULTS:The prevalence of anemia was high in all ages groups and highest (67.6%) in children aged &lt;5 years with a mean hemoglobin of 10.37 g/dL (±1.30 g/dL). Children aged &lt;5 years had low percentage of iron intake adequacy (53.1%). Most of them consumed diets with low iron bioavailability (47.5%). Associations between the occurrence of anemia and dietary variables were significant for total iron (heme and nonheme), its bioavailabilities, and general meat intake.CONCLUSION:Inadequate dietary iron intake and inadequate intake of factors that facilitate iron absorption can be considered decisive for the occurrence of iron-deficiency anemia. Food insecurity occurs between family members, with some members being favored over others with regard to the intake of good dietary iron sources.

title: Refinement of the Brazilian Household Food Insecurity Measurement Scale: Recommendation for a 14-item EBIA

description: OBJECTIVE:To review and refine Brazilian Household Food Insecurity Measurement Scale structure.METHODS:The study analyzed the impact of removing the item "adult lost weight" and one of two possibly redundant items on Brazilian Household Food Insecurity Measurement Scale psychometric behavior using the one-parameter logistic (Rasch) model. Brazilian Household Food Insecurity Measurement Scale psychometric behavior was analyzed with respect to acceptable adjustment values ranging from 0.7 to 1.3, and to severity scores of the items with theoretically expected gradients. The socioeconomic and food security indicators came from the 2004 National Household Sample Survey, which obtained complete answers to Brazilian Household Food Insecurity Measurement Scale items from 112,665 households.RESULTS:Removing the items "adult reduced amount..." followed by "adult ate less..." did not change the infit of the remaining items, except for "adult lost weight", whose infit increased from 1.21 to 1.56. The internal consistency and item severity scores did not change when "adult ate less" and one of the two redundant items were removed.CONCLUSION:Brazilian Household Food Insecurity Measurement Scale reanalysis reduced the number of scale items from 16 to 14 without changing its internal validity. Its use as a nationwide household food security measure is strongly recommended.

title: Folate inadequacy in the diet of pregnant women

description: OBJECTIVE:To estimate food and dietary folate inadequacies in the diets of adult pregnant women.METHODS:A prospective study was conducted with 103 healthy pregnant adult users of the Public Health Care System of Ribeirão Preto, São Paulo,Brazil. The present study included the 82 women with complete food intake data during pregnancy, which were collected by three 24-hour dietary recalls. Food folate (folate naturally present in foods) and dietary folate (food folate plus folate from fortified wheat flour and cornmeal) inadequacies were determined, using the Estimated Average Requirement as cutoff.RESULTS:The diets of 100% and 94% of the pregnant women were inadequate in food folate and dietary folate, respectively. However, fortified foods increased the medium availability of the nutrient by 87%.CONCLUSION:The large number of pregnant women consuming low-folate diets was alarming. Nationwide population studies are needed to confirm the hypothesized high prevalence of low-folate diets among pregnant women.

title: Reference serving sizes for the Brazilian population: An analysis of processed food labels

description: OBJECTIVE:To compare serving sizes reported on processed food labels with reference serving sizes according to nutrition labeling legislation and the "Food Guide for the Brazilian Population".METHODS:This cross-sectional study analyzed the labels of 2,072 processed foods in a supermarket of Florianópolis, Santa Caratina, Brazil. The foods were classified according to the Brazilian food labeling legislation. Central tendency and variability values were calculated for the serving sizes and energy values reported on the labels, as well as the ratio between the reported and reference energy value. The Spearman correlation test was performed between the reference serving size and the reference energy density, and also between the reference serving size and energy density of each study food.RESULTS:Nutrition labeling and the Food Guide presented reference servings with different sizes and energy values. The serving sizes reported on the labels did not follow either of the references and presented heterogeneous values, with a maximum range of 55-240 g among ready and semi-ready pre-prepared dishes. The reported energy values were between 0.1 times smaller and 2.4 times larger than the reference values. The reference serving sizes presented a highly inverse correlation with the reference energy density (Spearman coefficient= 0.9) and a very low inverse correlation with the energy density of the foods analyzed (Spearman coefficient= 0.2).CONCLUSION:This study showed the need for standardizing reference serving size information for the Brazilian population as well as reviewing nutrition labeling legislation in order to standardize the serving sizes reported on labels and to update the reference energy density used to calculate serving sizes.

title: Factors associated with the consumption of fruits and vegetables in schoolchildren aged 7 to 14 years of Florianópolis, South of Brazil

description: Objective: To estimate the prevalence of the fruit and vegetable intake of schoolchildren aged 7 to 14 years from Florianópolis, Santa Catarina, Brazil, and analyze the associated factors. Methods: This cross-sectional study analyzed food intake, socioeconomic, and biological data of 2,836 schoolchildren. The Chi-square test analyzed the dependent (fruit and vegetable intake) and independent variables; the latter with p-value &lt;0.20 were selected for logistic regression analysis. The level of significance was p&lt;0.05. Results: Only 4.8% of the sample had adequate fruit and vegetable intake. The variables associated with adequate fruit and vegetable intake were school ownership status (private versus public), mother's education level, and family income per member. After adjustment only family income per capita remained associated with fruit and vegetable intake. Conclusion: The fruit and vegetable intake of schoolchildren aged 7 to 14 years from Florianópolis, Santa Catarina, Brazil, is inadequate.
