Objectives: To identify dietary patterns in pre-school children and to investigate its determinants. Methods:Cross-sectional study nested in a cohort born between 2004 and 2005 in the municipality of Diamantina, state of Minas Gerais, Brazil. The instrument used to explore the dietary patterns was a frequency questionnaire for food consumption. Factor analysis was used for the identification of the dietary patterns. The study also assessed personal and socioeconomic data and anthropometric measurements of 232 preschoolers in the period between July 2009 and July 2010. The determinants of food patterns were identified by logistic regression.Results: Three patterns were obtained, which were called: "mixed diet," "snack," and "unhealthy." The children of mothers with low education are more likely (odds ratio -OR = 3.80; confidence interval 95% -95%CI = 1.90-7.60) to consume food from the "mixed diet" pattern, and less likely (OR = 0.31; 95%CI = 0.15-0.61) to consume food from the "snack" pattern, while those with higher per capita income are more likely to consume food from the "unhealthy" pattern (OR = 2.43; 95%CI = 1.13-5.24). Conclusion:Three dietary patterns were identified in the studied population, which were determined by the level of maternal education and per capita income. Resultados: Três padrões foram obtidos, denominados de "dieta mista", "lanche" e "não saudável". Os pré-escolares filhos de mães com menor escolaridade têm mais chance (odds ratio -OR = 3,80; intervalo de confiança de 95% -IC95% = 1,90-7,60) de consumir alimentos do padrão "dieta mista" e menor chance (OR = 0,31; IC95% = 0,15-0,61) de consumir alimentos do padrão "lanches", enquanto os de maior renda per capita têm mais chance de consumir alimentos do padrão "não saudável" (OR = 2,43; IC95% = 1,13-5,24). J Pediatr (Rio J) Conclusão:Foram identificados três padrões alimentares na população estudada, os quais foram determinados pelo nível de escolaridade materna e renda per capita.

Abstract

Objective: To verify the prevalence of intestinal parasitic infections among preschoolers and to identify the associated risk factors. Methods: The study is a cross-sectional study nested in a cohort of children who were born and resident in Diamantina, Minas Gerais, Brazil. At the time of the study, all children were aged 60 months 6 five months. They were recruited after written informed consent was obtained from parents or guardians. The study was carried out between July 2009 and July 2010. In total 214 children provided a stool sample for examination on intestinal parasitic infections. Information on potential risk factors for parasitosis was obtained from parents and guardians of the children by a questionnaire. Logistic regression was used for analysis. Results: Intestinal parasitic infections were found in 27.5% (n559) of children. The boys' infection prevalence (26.1%, n536) was slightly lower than the infection prevalence of the girls (30.3%, n523), but not statistically different (p50.51). Fourteen children, (23.7%) were infected with two or more parasite species and forty-five (76.3%) with single parasites. A low per capita income of family was strongly associated with an increased risk for an infection (OR52.89; P50.003). Preschoolers whose mothers did not work outside home had a significantly lower risk for infection (OR50.41; p50.01).
