Nevertheless, this has been the first attempt of using a multilevel approach to validate dietary intake in an international context, and an important understanding of between-center variation in nutrient intake bias as well as factors that can influence the performance of the method has been achieved.
These findings support the rationale for the design and testing of multilevel interventions to reduce obesogenic dietary intake in young preschool age children.
By using a multilevel modeling approach, we observed that the bias in protein intake did not vary across centers in men, but varied among women (5.7% of variation) in the crude model with random intercepts.
Respecting the environmental variables, the linear multilevel regression model showed a significantly association with the FV intake score in response to the increase of density of stores of fruit and vegetables in the neighborhood.
We used multilevel analyses to estimate the within-subject effects of SSB on food intake.
Putative within-day and longitudinal effects of maternal stress on children's dietary intake, physical activity, and body composition will be tested through multilevel modeling and latent growth curve models, respectively.
Multilevel linear regression adjusted for school clustering, SES, percentage of body fat, and total energy intake were used to investigate differences between log MVPA on days when inconsistent consumers ate or skipped breakfast.
Poor food intake is known to lead to malnutrition in long-term care homes (LTCH), yet multilevel determinants of food intake are not fully understood, hampering development of interventions that can maintain the nutritional status of residents.
Data are mean (95% confidence interval) based on multilevel mixed-effects linear regression, adjusted for age, sex, HIV status, alpha-1 glycoprotein, smoking habits, alcohol intake, and nutritional intervention.
