“…The food intake was evaluated by means of the semi-quantitative food frequency questionnaire (FFQ), comprising of 97 food elements. The questionnaire used has been designed and validated to infer the reality of the adolescents in Salvador [ 18 ]. The FFQ was applied by the same panel of trained dieticians who collected the epidemiological, clinical, and socioeconomic information, during a consultation with each study participant, who described their dietary habits.…”

“…Furthermore, the consumption of each food and/or preparations was standardized to read units of weight (g) and or volume (mL). This information was next used for computation of the daily ingestion of the food recorded through the FFQ as previously described [ 14 , 18 ]. The results of these calculations were deconvoluted to extrapolate the daily consumption [ 14 , 18 ].…”

Systems Nutrology of Adolescents with Divergence between Measured and Perceived Weight Uncovers a Distinctive Profile Defined by Inverse Relationships of Food Consumption

Changes in food consumption, physical inactivity, and other lifestyle habits are potential causes of the obesity epidemic. Paradoxically, the media promotes idealization of a leaner body appearance. Under these circumstances, self-perception of weight by adolescents may be affected. Here, we performed a cross-sectional study, between June and December 2009, to evaluate the interaction between anthropometric status, perceived body weight, and food consumption profiles in 1496 adolescents from public schools in Salvador, Brazil. Data on socio-epidemiological information, anthropometric status, and dietary patterns were analyzed using multidimensional statistical approaches adapted from systems biology. There were dissimilarities between anthropometric status and perception of body weight related to sex. Four dietary patterns were identified based on the food intake profile in the study participants. The distinct dietary patterns were not influenced by divergence between measured and perceived weight. Moreover, network analysis revealed that overestimation of body weight was characterized by a selectivity in ingestion of food groups that resulted in appearance of inverse correlations of consumption. Thus, misperception of body weight is associated with inverse correlations of consumption of certain food groups. These findings may aid individualized nutritional interventions in adolescents who overestimate body weight.

“…The food intake was assessed using the semi-quantitative food frequency questionnaire (FFQ), consisting of 97 food items. The questionnaire used was constructed to fit the reality of the students of public schools in Salvador and later validated by our group [13]. The FFQ was applied directly to the students, who reported on their food consumption outside and inside the household.…”

“…After the data collection, by using food composition and nutrition tables, we standardized the consumed quantities of each food and/or preparations referred to units of weight (g) and or volume (mL), which were used for calculation of the daily consumption of the food registered with the FFQ. Using this approach, data collected to measure consumption of food in a month (total month consumption) was deconvoluted to infer daily consumption (divided by number of days in a given month) as previously described [13]. Industrialized foods and/or preparations that were not included in the tables were searched via internet directly on the manufacturer’s website or through recipes.…”

Multidimensional Analysis of Food Consumption Reveals a Unique Dietary Profile Associated with Overweight and Obesity in Adolescents

There is a significant increase in overweight and obesity in adolescents worldwide. Here, we performed a cross-sectional study to examine the potential association between food consumption profiles and overweight in a large number of adolescents from Brazil. Sampling by clusters and conglomerates was carried out in students of public schools in Salvador, Brazil, between June and December 2009 and 1496 adolescents were evaluated. Data on socio-epidemiological data, anthropometric status and food consumption were captured. Multivariate analyses, such as hierarchical clustering and correlation networks, were used to perform a detailed description of food consumption profiles. There were differences in age and anthropometric status related to sex. Four clusters of food groups were identified based on the intake profile in the study population. No disparities in food intake were observed in individuals stratified by sex or anthropometric status. Furthermore, network analysis revealed that overweight or obesity were hallmarked by a selectivity in the ingestion of food groups that resulted in the appearance of inverse correlations of consumption, which was not present in eutrophic adolescents. Thus, overweight and obesity are associated with preferential choices of ingestion of specific food groups, which result in the appearance of inverse correlations of consumption. Such knowledge may serve as basis for future targeted nutritional interventions in adolescents.
