Identification of food intake patterns and associated factors in teenagers

Abstract

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<0.001). The "traditional pattern" was negatively associated with classes D, C, and B (β=-0.149, p<0.007), and the "healthy pattern" was negatively associated with females (β=-0.200, p>0.0001) and classes D, C, and B (β=-0.125, p<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.

Padrões alimentares de adolescentes brasileiros por regiões geográficas: análise do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA)

“…According to the current study's results, male adolescents appear to have a healthier dietary pattern, since they show greater adherence to the traditional pattern and lower adherence to the unhealthy pattern, compared to female adolescents. Similar results were found in a study of adolescent students in public schools in Bahia, where the "healthy" pattern was inversely associated with female adolescents 17 .…”

“…In the last five years, it has been witnessed a trend in the use of methodologies for assessing food consumption in Brazilian children and adolescents based on the identification of dietary patterns 11,12,13,14,15,16,17,18,19,20,1,21,22 . However, such studies involve localized samples, denoting a gap in studies with nationally representative probabilistic samples of Brazilian adolescents according to geographic region.…”

“…The increasing consumption of processed foods, either in developed [1] or developing countries [2], has led to concerns related to consequences on human health, especially metabolic disorders [3,4] and hypertension [5], as well as consequences for oral health that can affect dental elements, such as pain, decreased masticatory efficiency and aesthetic changes [6].…”

“…Entre os estudos que investigaram a relação entre hábitos alimentares, atividade física e fatores socioeconômicos, cinco encontraram associação negativa significativa (MASCARENHAS et al, 2014;AMBROSINI et al, 2009;BIBILONI et al, 2012;SHI et al, 2005;TRANG et al, 2013) e oito encontraram associação positiva (BRODERSEN et al, 2005;JOHANSEN;RASMUSSEN;MADSEN, 2006;BRODERSEN et al, 2007;MACFARLANE et al, 2007;PEARSON et al, 2009;PITEL et al, 2010;CUTLER et al, 2011;PITEL et al, 2013;). Em 2 estudos (KOURLABA et al, 2009RIDDOCH et al, 2007 não foram observadas associações estatisticamente significantes.…”
