Contribution of vegetable soup to total vegetables intake and its determinants among mothers in Portugal

Abstract

Purpose - This paper's aim is to assess vegetable soup intake and its contribution to total vegetable intake among mothers of Portuguese schoolchildren as well as to examine the association between relative vegetable soup intake and sociodemographic characteristics. Design/methodology/approach - A cross-sectional survey was carried out in Portugal as part of the Pro Children study. In total 1,673 women, mothers of 11-13 year old children, took part in the study. The vegetable intake and sociodemographic characteristics were collected with a self-administered questionnaire in which a precoded 24-hour recall was applied. The analysed sociodemographic characteristics were the number of people and composition of household, educational level, social class and region of residence The associations between preferential or exclusive consumer mothers of vegetable soup (i.e. >= 50 per cent. of total vegetable intake) and sociodemographic characteristics were analysed by a logistic regression model. Findings - The mean intake of vegetable soup was 76.1 g/d and its contribution to total vegetable intake was approximately 45 per cent. The percentage of mothers that were preferential or exclusive consumers of vegetable soup was 41 per cent. Preferential or exclusive vegetable soup intake was less likely among mothers when the number of people in the household was less than four (vs 4; OR: 0.734, 95 per cent CI: 0.577-0.934) and that did not live with their spouse/partner (OR: 0.617, 95 per cent CI: 0.424-0.878). Originality/value - The paper focuses on the consumption of vegetable soup, a traditional culinary preparation among Portuguese people. Also, it identifies factors associated with its consumption.
