Advanced Search Abstract Background: We compared three commonly used statistical models to assess the effect of maternal body mass index BMI on growth between 6. Model 1 analysis of the difference in anthropometric measurements between the two ages; Model 2 analysis of the measurement at We show that these larger effects arise because Model 2 parameterizes the effect of maternal BMI twice in same model: Similar results were obtained in analogous analyses from cohorts in Boston, MA, and Singapore.
Early growth has been studied as an exposure causing long-term adult outcomes like high blood pressure, coronary artery disease and diabetes 1 ; as an outcome caused by maternal and familial influences, including infant feeding, later diet and physical activity 2—9 ; and as a causal intermediate between early life exposures and later chronic disease.
It can be characterized by its overall trajectory, using either parametric or nonparametric longitudinal models. Other attempts have focused on age period-specific effects.
Investigators of childhood growth have therefore analysed growth in specific age periods by employing a variety of statistical adjustment methods for size attained at earlier ages and even, in some studies, at later ages as well. Using the same dataset, we compare the results of the different analytical approaches, discuss the potential biases associated with each, and recommend strategies for future research.
Briefly, the clusters randomized were maternity hospitals and one affiliated polyclinic outpatient clinic where children receive routine health care per hospital. Clusters were randomized to a control intervention continuation of the breastfeeding practices and policies in effect at the time of randomization or an experimental intervention based on the Baby-Friendly Hospital Initiative.
Follow-up interviews and examinations at 6.

|Assuring the health of the public, however, goes beyond focusing on the health status of individuals; it requires a population health approach. As noted in Chapter 1America's health status does not match the nation's substantial health investments.|

The training and quality assurance procedures at both the 6. We considered three statistical analytical approaches to estimate the causal effect of maternal obesity on growth in height, weight and adiposity between the ages of 6.
For ease of interpretation and comparison, all outcome trajectories are represented by straight lines. As graphically depicted in Figure 1the simplest method Model 1 of analysis is to compare the mean change in the anthropometric measure between 6.
Figure 1 View large Download slide Graphical depiction of trajectory growth in anthropometric outcomes to ages 6. Growth is assumed to be linear from birth to age According to Model 1, the differences in outcome at age 6.

Countries such as India have little prospect.
