Fathers' use of social media for social comparison is associated with their food parenting practices.

Over 85% of parents use social media; however, limited research has investigated the associations between parental social media use and food parenting practices. The objectives of this study were to: 1) describe how mothers and fathers use social media focused on topics related to child feeding and family meals; and 2) examine associations between parental social media use focused on child feeding and family meals and mothers' and fathers' food parenting practices. Data were obtained from 179 mothers and 116 fathers of children aged 3-8 years enrolled in a family-based obesity prevention intervention. We used descriptive statistics to describe parents' social media use in relation to child feeding and family meals and linear regressions with generalized estimating equations to explore associations between parents' social media use and food parenting practices. Models were stratified by parent gender and adjusted for household income, parent ethnicity, parent age, child sex, and intervention status. A higher percent of mothers than fathers reported using social media to seek information related to child feeding and family meals (64.8% mothers; 25.0% fathers) and to share and compare family meals and food choices (41.9% mothers; 19.8% fathers). While social media use was not associated with food parenting practices in mothers, fathers' social media use to share and compare family meals and food choices was associated with negative food parenting practices, i.e., greater use of food for emotional regulation (ß = 0.37, p = 0.02) and greater use of food for reward (ß = 0.34, p = 0.02). Study results can inform strategies to promote healthy social media use among parents of young children.

Development, validity and reliability assessment of the Canadian Food Literacy Measure.

Food literacy is a growing area of interest given its potential to support healthy and sustainable diets. Most existing food literacy measures focus on nutrition and food skills but fail to address food systems and socio-environmental aspects of food literacy. Further, measures developed and tested in the Canadian context are lacking. The objective of this project was to develop and test the validity and reliability of a brief self-administered measure, in French and English, designed to assess multiple dimensions of food literacy among adults living in Canada. The 23-item Canadian Food Literacy Measure was developed through an iterative process that included assessment of face and content validity through expert review (n=20) and cognitive interviews (n=20), and construct validity and reliability, i.e., internal consistency through an online survey (n=154). The results indicate that the measure is well understood by both English- and French-speaking adults. The measure's construct validity is demonstrated by the observed differences in total scores in hypothesized directions by gender (p=0.003), age (p=0.007), education level (p=0.002), health literacy (p<0.001) and smoking status (p=0.001) and the significant positive correlation (r = 0.29; p=0.002) between total scores and fruit and vegetable intake. The measure also has high internal consistency with a Cronbach's coefficient alpha of 0.80. This measure can be used in surveillance studies to provide insight into the food literacy of adults living in Canada and in epidemiologic research that aims to explore how food literacy is associated with a variety of health outcomes.
