Resemblance of Diet Quality in Families of Youth with Type 1 Diabetes Participating in a Randomized Controlled Behavioral Nutrition Intervention Trial in Boston, MA (2010-2013): A Secondary Data Analysis.

ABSTRACT: BACKGROUND:Parent-child diet quality resemblance is unknown in families of youth with type 1 diabetes, for whom nutrition is central to disease management. OBJECTIVE:Examine diet quality resemblance in families of youth with type 1 diabetes participating in a behavioral nutrition intervention trial and investigate whether treatment assignment or family meal frequency modifies resemblance. DESIGN:This is a secondary data analysis from an 18-month randomized controlled trial conducted August 2010 to May 2013. PARTICIPANTS/SETTING:Parent-youth dyads (N=136, child age=12.3±2.5 years) were recruited from a northeast US diabetes center. MAIN OUTCOME MEASURES:Parent and child Healthy Eating Index-2005 (HEI-2005, reflecting adherence to 2005 Dietary Guidelines for Americans) and whole plant food density (WPFD, reflecting intervention target foods) were calculated from 3-day food records collected every 6 months. STATISTICAL ANALYSIS:Linear random effects models adjusting for demographics and disease characteristics investigated parent-child diet quality resemblance. Separate models examined whether treatment assignment or family meal frequency modified resemblance. Three-way interaction terms examined whether resemblance changed over time by treatment assignment. RESULTS:Time-varying parent and child HEI-2005 and WPFD were positively associated (P<0.001), and there were no interactions with family meals. Parent-child HEI-2005 resemblance was similar across treatment groups; however, parent-child WPFD resemblance was stronger in the intervention (?±standard error [SE]=.30±.06) vs control families (?±SE=.12±.05). Parent-child HEI-2005 resemblance was similar over time by treatment assignment, whereas parent-child WPFD resemblance increased over time for families in the intervention group (three-way interaction term ?±SE=.03±.01). CONCLUSIONS:Parent and youth diet quality were positively correlated in families of youth with type 1 diabetes. Resemblance was stronger in the intervention group for target foods, but not for a general measure of diet quality. The lack of effect modification by family meal frequency suggests that family diet quality resemblance is not contingent on shared meals.

Project description:Identifying the sources, composition, and temporal variability of fine (PM2.5) and coarse (PM2.5-10) particles is a crucial component in understanding particulate matter (PM) toxicity and establishing proper PM regulations. In this study, a Harvard Impactor was used to collect daily integrated fine and coarse particle samples every third day for 9 years at a single site in Boston, MA. In total, 1,960 filters were analyzed for elements, black carbon (BC), and total PM mass. Positive Matrix Factorization (PMF) was used to identify source types and quantify their contributions to ambient PM2.5 and PM2.5-10. BC and 17 elements were identified as the main constituents in our samples. Results showed that BC, S, and Pb were associated exclusively with the fine particle mode, while 84% of V and 79% of Ni were associated with this mode. Elements mostly found in the coarse mode, over 80%, included Ca, Mn (road dust), and Cl (sea salt). PMF identified six source types for PM2.5 and three source types for PM2.5-10. Source types for PM2.5 included regional pollution, motor vehicles, sea salt, crustal/road dust, oil combustion, and wood burning. Regional pollution contributed the most, accounting for 48% of total PM2.5 mass, followed by motor vehicles (21%) and wood burning (19%). Source types for PM2.5-10 included crustal/road dust (62%), motor vehicles (22%), and sea salt (16%). A linear decrease in PM concentrations with time was observed for both fine (-5.2%/yr) and coarse (-3.6%/yr) particles. The fine-mode trend was mostly related to oil combustion and regional pollution contributions. Average PM2.5 concentrations peaked in summer (10.4 µg/m3), while PM2.5-10 concentrations were lower and demonstrated little seasonal variability. The findings of this study show that PM2.5 is decreasing more sharply than PM2.5-10 over time. This suggests the increasing importance of PM2.5-10 and traffic-related sources for PM exposure and future policies.Although many studies have examined fine and coarse particle composition and sources, few studies have used concurrent measurements of these two fractions. Our analysis suggests that fine and coarse particles exhibit distinct compositions and sources. With better knowledge of the compositional and source differences between these two PM fractions, better decisions can be made about PM regulations. Further, such information is valuable in enabling epidemiologists to understand the ensuing health implications of PM exposure.

Project description:BackgroundStudies investigating dietary resemblance between parents and their children have gained mixed results, and the resemblance seems to vary across nutrients, foods, dietary-assessment tools used, and parent-child pairs. We investigated parent-child dietary resemblance using a novel approach in applying statistical analysis, which allowed the comparison of 'whole-diet' between parents and their children. Additionally, we sought to establish whether sociodemographic factors or family meals were associated with dietary resemblance and whether parent-child dietary resemblance was dependent on the parent providing food consumption data on behalf of the child (father or mother, "the respondent").MethodsThe DAGIS study investigated health behaviors among Finnish preschoolers using a cross-sectional design. One parent filled in a food frequency questionnaire (FFQ) measuring the child's food consumption outside preschool hours during the last week. In addition, we instructed both parents or legal guardians, should the child have two, to fill in a similar FFQ regarding their own food use. Parents also reported their educational level, the number of children living in the same household, and the number of family meals. As a measure of dietary resemblance between a parent and a child, we computed Spearman correlations ranging mostly from no resemblance (0) to complete resemblance (+ 1) between parent-child pairs over the 'whole-diet' (excluding preschool hours). These resemblance measures were further investigated using linear mixed models.ResultsWe obtained 665 father-child and 798 mother-child resemblance measures. Mother-child resemblance was on average 0.57 and stronger than father-child resemblance (0.50, p < 0.0001), which was explained by a parent-respondent interaction: the diet of the child resembled more the diet of the parent who provided food consumption data for the child. In univariate models, father- and mother-reported number of family meals were positively associated with father-child and mother-child resemblances. Mother-reported number of family meals was positively associated with mother-child resemblance in a full model.ConclusionsThe diet of the child seems to resemble more the diet of the parent responsible for the reporting of food consumption. Studies should report who provided the food consumption data for the child and take this into account in analyses, since reporter-bias can influence the results.
