Abstract
Background:
Late achievement of motor milestones may increase the risk of overweight since early achievers
have an increased opportunity to build lean body mass and expend energy.
Overweight infants may have delayed achievement of gross motor milestones, as excess body fat
limit mobility.
Aim:
1. To investigate whether delayed ability to sit and walk is associated with overweight at age 7 years
2. To examine whether age (in months) at achieving the ability to sit and walk is associated with a
higher BMI at age 7.
3. To examine whether increasing weight at birth and at 5 months of age postpone the achievement
of the ability to sit and walk independently.
Methods:
Data: The Danish National Birth Cohort. Study
population consisted of 32,973 children who were
followed from birth to age 7. Children were born
between 1998 and 2003 and follow-up took place
from 2003 to2010. Information on height and
weight in infancy was obtained from the GP and
information on motor milestone achievement and
on height and weight age 7 years was reported by
the parents.
Data analysis: Logistic and linear regression.
Results:
Weight status in the study population, n=32,793
1: Late ability to sit (>8 months) and to walk (>15 months)
was not associated with overweight at age 7.
Gender specific OR’s between:
1.00; (CI 0.98-1.02) and 1.02; (CI 0.95-1.07)).
2: Age of achievement of sitting and walking independently
was weakly inverse associated with BMI at age 7.
Gender specific BMI z-scores between: -0.029 (CI -0.038; -
0.019) and -0.015 (CI -0.023; -0.006) which corresponds to a
BMI in the range -0.3% to -0.2% at age 7 years.
3: Increased birth weight (in 500 grams intervals) and BMI at
5 months of age was weakly inverse associated with
achievement of the ability to sit and walk independently
β-coefficients between:
-0.05 months; (CI -0.09; -0.01) and -0.08 months (CI -0.014; -
0.02).
Conclusions from our study:
1) Delay in achievement of motor milestones does not predict later overweight among children.
2) Age in month of achieving the ability to sit and walk independently does not predict a higher BMI at age 7
3) Age of achieving motor milestones is largely independent of growth
