Experiencing food insecurity in childhood: influences on eating habits and body weight in young adulthood.

Objective: To examine how food insecurity in childhood up to adolescence relates to eating habits and weight status in young adulthood.

Design: A longitudinal study design was used to derive trajectories of household food insecurity from age 4·5 to 13 years. Multivariable linear and logistical regression analyses were performed to model associations between being at high risk of food insecurity from age 4·5 to 13 years and both dietary and weight outcomes at age 22 years.

Eating behaviors, dietary patterns and weight status in emerging adulthood and longitudinal associations with eating behaviors in early childhood.

Background: Eating behaviors may contribute to differences in body weight and diet over time. Our study aims to examine how eating behaviors of young adults relate to their current weight status and dietary patterns and to explore longitudinal associations with eating behaviors in early childhood.

Methods: Study participants are young adults (n = 698) taking part in the Quebec Longitudinal Study of Child Development.

Diet quality during pregnancy and its association with social factors: 3D Cohort Study (Design, Develop, Discover).

Good diet quality during pregnancy provides adequate nutrition to support both the mothers and the fetus. The objective of this study is to describe the distribution of diet quality during pregnancy and to study the association between social factors and diet quality during pregnancy in a Canadian population. This study was based on 1535 pregnant women who provided dietary information in the 3D Cohort Study in Quebec, Canada.

Breast-feeding, rapid growth in the first year of life and excess weight at the age of 2 years: the 3D Cohort Study.

Objective: To assess relationships between breast-feeding, rapid growth in the first year of life and overweight/obesity status at the age of 2 years.

Design: As part of an observational, longitudinal study beginning in early pregnancy, multivariable logistic regressions were used to assess associations between breast-feeding duration (total and exclusive) and rapid weight gain (RWG) between birth and 1 year of age, and to determine predictors of overweight/obesity status at the age of 2 years.

Setting: Nine hospitals located in the province of Quebec, Canada.

Adequacy of nutritional intake during pregnancy in relation to prepregnancy BMI: results from the 3D Cohort Study.

Our study compares adequacy of nutritional intakes among pregnant women with different prepregnancy BMI and explores associations between nutritional intakes during pregnancy and both prepregnancy BMI and gestational weight gain (GWG). We collected dietary information from a large cohort of pregnant Canadian women (n 861) using a 3-d food record. We estimated usual dietary intakes of energy (E), macronutrients and micronutrients using the National Cancer Institute method.

Adequacy of nutritional intake from food and supplements in a cohort of pregnant women in Québec, Canada: the 3D Cohort Study (Design, Develop, Discover).

Assessments of the dietary intakes in various populations suggest that pregnant women have difficulty meeting all their nutritional requirements through diet alone. Few large-scale studies have considered both food sources and supplements in assessing the adequacy of nutritional intakes during pregnancy. Our study aimed to assess nutritional intakes during pregnancy by examining dietary sources and supplements.

Dietary Intake at 9 Years and Subsequent Body Mass Index in Adolescent Boys and Girls: A Study of Monozygotic Twin Pairs.

There is a lack of evidence pointing to specific dietary elements related to weight gain and obesity prevention in childhood and adulthood. Dietary intake and obesity are both inherited and culturally transmitted, but most prospective studies on the association between diet and weight status do not take genetics into consideration. The objective of this study was to document the association between dietary intake at 9 years and subsequent Body Mass Index (BMI) in adolescent monozygotic boy and girl twin pairs.

Genetic and environmental influences on eating behaviors in 2.5- and 9-year-old children: a longitudinal twin study.

Background: Eating behaviors during childhood are related both to children's diet quality and to their weight status. A better understanding of the determinants of eating behavior during childhood is essential for carrying out effective dietary interventions.

Methods: We assessed the contribution of genetic and environmental factors to variations in selected eating behaviors in early and late childhood.

Gene-environment contributions to energy and macronutrient intakes in 9-year-old children: results from the Quebec Newborn Twin Study.

Background: Few twin studies have examined nutrition-related phenotypes among children, and none has investigated energy and macronutrient intakes.

Objective: The objective was to quantify genetic and environmental influences on variations in energy and macronutrient intakes among children aged 9 years.

Design: We conducted a nutrition study among children participating in the Quebec Newborn Twin Study, a population-based birth cohort of twins.
