Dietary patterns and their determinants in a sampleof 6 to 12 year old Swiss childrenSara Della BellaS Della Bella1, S Suggs1, P Marques-Vidal2, N Rangelov11Institute for Public Communication (ICP), Universita` della Svizzera Italiana,Lugano, Switzerland2Faculte´ de biologie et me´decine, UNIL-CHUV, Lausanne, SwitzerlandContact: dellasa@usi.chBackgroundDiet is a crucial determinant of health. Since individual fooditems are eaten in combination, the assessment of eatingpatterns (as an alternative to the single food approach) isimportant to realistically evaluate a person’s diet. Equallyimportant is the investigation of the determinants of suchpatterns, which can suggest targets for future interventions.MethodWe used Principal Component Analysis (PCA) to reduce datainto patterns based upon inter-correlations between dietaryitems, in a sample of children ages 6–12 in Switzerland(n = 607) who enrolled in the FAN project (Family, physicalActivity and Nutrition) and completed a 7-day food diary in2010. These data were used to calculate the daily consumptionfor eight food groups. Participants received a score for eachderived pattern. From these, a set of dummy variables werecreated synthesizing whether a participant belongs to thehighest percentile of a particular pattern. We then investigatethe association between belonging to the highest quintile of apattern and a set of socio-demographic variables using bothcross-tabulations and multivariate logistic regressions.ResultsPCA reveals four dietary patterns: the first characterized by ahigh consumption of fruits and vegetables; the secondcharacterized by high intake of meat and sweets, salty snacksand sugary drinks; the third characterized by high consump-tion of dairy and farinaceous and the fourth characterized by ahigh intake of fish and a low intake of eggs. Preliminary resultsshow that being female is associated with belonging to thehighest quintile of the fruits and vegetables dietary pattern(Chi2 = 14,598, p = 0,000) and that the coefficient of genderremains statistically significant in the logistic model(exp() = 2,128, p = 0,001).ConclusionsFemale are more than twice as likely as male to belong to thehighest quintile of the healthiest dietary patterns, characterizedby high intake of fruit and vegetables.Key message Boys should be targeted in interventions aiming at increasingthe consumption of fruits and vegetables among children8th European Public Health Conference: Parallel Sessions 163
