Abstract

Background Recommendations for preconception care usually include optimal
nutrition and physical activity, but these have not been tested extensively for their relationship with birth outcomes such as low birthweight and preterm birth.

Methods Data from Waves I, II and IV of the National Longitudinal Study of
Adolescent Health (Add Health) contractual dataset were utilized. In Wave I in-home
M AN U
interview, participants were asked to recall their frequency of having five types of food on the previous day, including milk, fruit, vegetables, grains, and sweets. At Wave II, participants reported the previous day’s intake of 55 items, and results were categorized into high-calorie sweet, high-calorie non-sweet, and low-calorie food. At Wave I in-
TE D
home interview, participants were also asked how many times in a week or during the past week they were involved in types of physical activity. At Wave IV, female participants reported pregnancies and birth outcomes. Multivariable linear regression
EP
analysis with survey weighting was used to predict birthweight and gestational age. Results There were no associations between reported food intake and birth outcomes.
