Recent national surveys in Brazil have demonstrated a decrease in the consumption of traditional food and a parallel increase in the consumption of ultra-processed food, which has contributed to a rise in obesity prevalence in all age groups. Environmental factors, especially familial factors, have a strong influence on the food intake of preschool children, and this has led to the development of psychometric scales to measure parents’ feeding practices. The aim of this study was to test the validity of a translated and adapted Comprehensive Feeding Practices Questionnaire in a sample of Brazilian preschool-aged children enrolled in private schools. A transcultural adaptation process was performed in order to develop a modified questionnaire (43 items). After piloting, the questionnaire was sent to parents, along with additional questions about family characteristics. Test-retest reliability was assessed in one of the schools. Factor analysis with oblique rotation was performed. Internal reliability was tested using Cronbach’s alpha and correlations between factors, discriminant validity using marker variables of child’s food intake, and convergent validity via correlations with parental perceptions of perceived responsibility for feeding and concern about the child’s weight were also performed. The final sample consisted of 402 preschool children. Factor analysis resulted in a final questionnaire of 43 items distributed over 6 factors. Cronbach alpha values were adequate (0.74 to 0.88), between-factor correlations were low, and discriminant validity and convergent validity were acceptable. The modified CFPQ demonstrated significant internal reliability in this urban Brazilian sample. Scale validation within different cultures is essential for a more comprehensive understanding of parental feeding practices for preschoolers.

Eating habits formed in early childhood are influenced by parental feeding behaviors, warranting investigation of predictors and correlates of parent feeding. We aimed to describe relationships between parental feeding practices and parent and child characteristics in a sample of Brazilian preschoolers. Four hundred and two parents of preschoolers enrolled in private schools of São Paulo and Campinas, Brazil, completed a Brazilian version of the Comprehensive Feeding Practices Questionnaire, as well as questions about parental attitudes, child food intake, other obesity-associated behaviors, and socioeconomic and demographic characteristics. We ran bivariate logistic regression models examining associations between independent variables and each feeding practice. Next, we ran multiple logistic regression models predicting each parental feeding practice. Greater ‘Restriction for Weight Control’ and ‘Restriction for Health’ were associated with lower maternal education (OR = 2.42 (CI 95% 1.07–5.48) and 2.79 (CI 95% 1.25–6.22), respectively), and with higher concern about child overweight (OR = 2.46, CI 95% 1.64–3.69 for ‘Restriction for Weight Control’, only), while greater ‘Pressure’ was associated with greater concern about child underweight (OR = 2.30, CI 95% 1.53–3.47) and lower maternal BMI (OR = 0.94, CI 95% 0.88–1.00). Greater use of ‘Emotion Regulation/ Food as Reward’ was associated with lower maternal education (OR = 2.22, CI 95% 1.05–4.71). In analyses of positive feeding practices, lesser use of ‘Healthy Eating Guidance’ and ‘Monitoring’ was associated with greater intake of less healthy foods in children (OR = 1.53 (CI 95% 1.01–2.32) and OR = 1.94 (CI 95% 1.27–2.97), respectively), and greater use of screen devices (OR = 1.59 (CI 95% 1.04–2.44) and OR = 1.57 (CI 95% 1.03–2.39), respectively). Lesser use of ‘Healthy Eating Guidance’ was additionally associated with higher maternal BMI (OR = 1.09, CI 95% 1.03–1.16), and lesser use of ‘Monitoring’ with lesser perceived parent responsibility for child feeding (OR = 1.68, CI 95% 1.12–2.52). Our results demonstrate diverse socioeconomic, anthropometric and behavioral correlates of parent feeding in a large Brazilian sample of parents of preschoolers.

Maintaining a healthy weight may involve compensating for previously consumed calories at subsequent meals. To test whether heavier children demonstrated poorer caloric compensation across a range of conditions, and to explore whether compensation failure was the result of inadequate adjustment of overall intake or specific over-consumption of highly palatable, high energy-density 'junk' foods, we administered two compensation tests to a sample of 4-5 y olds. For Test A, preloads varied only in carbohydrate content and were organoleptically indistinguishable (200 ml orange-flavored beverage [0 kcal vs. 200 kcal]). For Test B, the preloads varied substantially in both macronutrient composition and learned gustatory cues to caloric content (200 ml water [0 kcal] vs. 200 ml strawberry milkshake [200 kcal]). Each preload was followed 30 min later by a multi-item ad-libitum meal containing junk foods (chocolate cookies, cheese-flavored crackers) and core foods (fruits and vegetables, bread rolls, protein foods). Testing took place at the children's own school under normal lunch-time conditions. Children were weighed and measured. Caloric compensation occurred in both tests, in terms of total, junk and core food intake (RMANOVA, all p < 0.01). Higher BMI z scores were associated with greater average caloric compensation (r = -0.26; p < 0.05), such that overweight/obese children showed least compensation (41%), children over the 50th centile the next least (59%), and children under the 50th centile (80%) the most. For Test A only, obese/overweight children compensated less well than normal-weight children in terms of junk food intake (RMANOVA preload-by-weight group interaction p < 0.05), with no significant effect for core foods. Our results suggest that caloric compensation is consistently poorer in heavier children, and that overweight/obese children's preferences for junk foods may overwhelm intake regulation mechanisms within meals containing those foods.

To identify associations between maternal restrictive feeding practices for child weight control and sociodemographic, behavioral, dietetic, and anthropometric characteristics. Cross-sectional study with mothers of children aged 2-8 years. Maternal feeding practices were measured by the Comprehensive Feeding Practices Questionnaire, in private schools in Brazil. Bivariate and multivariate associations were performed, using nonparametric analyses to estimate odds ratios and significance levels. Maternal restrictive feeding practices for weight control were independently associated with the mother's perception of her child being a little overweight/overweight/obese (OR=4.61, p=0.001), greater concern about the child's overweight (OR=2.61, p<0.001), child's overweight/obesity/severe obesity (OR= 2.18, p<0.001), and the child's greater intake of ultra-processed foods (OR=1.40, p=0.026). In this study, the risk variables identified for the use of the maternal restrictive feeding practices to control the child's weight can be used to provide education and guidance interventions in health and education networks directed to groups with similar characteristics to those of the studied population.

Summary: Background: Child food intake and appetitive behaviors show an inconsistent pattern of associations with parental feeding practices. Relationships likely vary depending on parent feeding style, and on the method by which child eating behaviors are measured.Objectives: We tested relationships of controlling and less controlling forms of parental promotion and limitation of eating with food intake and appetitive behaviors assessed in preschoolers' normal school environments.Methods: As part of a 5‐day protocol, preschoolers consumed standardized lunches, and caloric compensation, eating rate and eating in the absence of hunger were assessed. Feeding practices were measured using the Child Feeding Questionnaire (CFQ) and Parent Feeding Styles Questionnaire (PFSQ). CFQ‐Pressure to eat and CFQ‐Restriction were controlling forms of promotion/limitation of child intake, and CFQ‐Monitoring and PFSQ‐Prompting to eat were less controlling forms.Results: Children (3–5y, n = 70) of parents with higher CFQ‐Pressure to eat scores showed lower total intake, consuming significantly fewer calories from bread, snacks and fruits and vegetables. Higher PFSQ‐Prompting to eat was associated with lower fruit and vegetable intake only. CFQ‐Restriction and CFQ‐Monitoring scores were unassociated with food intake. Higher CFQ‐Pressure to eat was associated with slower eating rate, while higher CFQ‐Monitoring was associated with lower intake in absence of hunger.Conclusions: Parental promotion and limitation of intake were associated with preschoolers' eating behaviors assessed in an ecologically valid setting, without parents present. Controlling and less controlling forms showed differential patterns of associations. Results were consistent with child‐to‐parent and parent‐to‐child effects, but research using longitudinal designs is needed to test bidirectional relationships.

Objective: The present study aimed to identify food patterns among 2–9-year-olds and investigate sociodemographic, anthropometric and behavioural predictors of less healthy dietary patterns.Design: Cross-sectional study. Parents of 2–9-year-olds completed an FFQ and factor analysis was applied to identify dietary patterns. Parents also completed questionnaires assessing sociodemographic, anthropometric and behavioural characteristics of parents and children, including parental feeding practices.Setting: Participants were recruited from private schools of Campinas and São Paulo, SP, Brazil, between April and June 2014.Subjects: Parents of 2–9-year-olds (n 929).Results: Two dietary patterns emerged: ‘traditional food’ and ‘ultra-processed food’. Lower maternal education (OR=2·05, P=0·010) and higher maternal weight status (OR=1·43, P=0·044) were associated with a greater likelihood of the ultra-processed food pattern. Lower perceived parental responsibility for adequacy of food group intake (OR=2·41, P=0·020), and lower scores on the parental feeding practices of ‘Healthy Eating Guidance’ (OR=1·83, P<0·001) and ‘Monitoring’ (OR=2·52, P<0·001), were also associated with the presence of this pattern, as was higher child’s screen use during mealtimes (OR=1·61, P=0·004).Conclusions: The present study is the first to evaluate associations between less healthy dietary patterns of Brazilian 2–9-year-olds and parental feeding practices. Our findings highlight sociodemographic, anthropometric and behavioural factors within families that could be used to target tailored policies to at-risk populations.
