Abstract
BACKGROUND: Obesity and osteoporosis have origins in childhood, and both are
affected by dietary intake and physical activity. However, there is little
information on what constitutes a diet that simultaneously promotes low fat
mass and high bone mass accrual early in life. OBJECTIVE: Our objective was to
identify dietary patterns related to fat and bone mass in children during the
age period of 3.8-7.8 y. DESIGN: A total of 325 children contributed data from
13 visits over 4 separate study years (age ranges: 3.8-4.8, >4.8-5.8, >5.8-6.8,
and >6.8-7.8 y). We performed reduced-rank regression to identify dietary
patterns related to fat mass and bone mass measured by dual-energy X-ray
absorptiometry for each study year. Covariables included race, sex, height,
weight, energy intake, calcium intake, physical activity measured by
accelerometry, and time spent viewing television and playing outdoors. RESULTS:
A dietary pattern characterized by a high intake of dark-green and deep-yellow
vegetables was related to low fat mass and high bone mass; high processed-meat
intake was related to high bone mass; and high fried-food intake was related to
high fat mass. Dietary pattern scores remained related to fat mass and bone
mass after all covariables were controlled for (P < 0.001-0.03). CONCLUSION:
Beginning at preschool age, diets rich in dark-green and deep-yellow vegetables
and low in fried foods may lead to healthy fat and bone mass accrual in young
children.
