Summary

Twinning does not impact the achievement of early motor milestones when compared to singletons. However, dizygotic (DZ) twins develop motor skills faster than monozygotic (MZ) twins, and later birth cohorts show delays in gross motor development.

Area of Science:

  • Developmental Pediatrics
  • Twin Studies
  • Motor Development

Background:

  • Twinning may influence the attainment of early motor milestones.
  • Understanding factors affecting motor development in infants is crucial for early intervention.

Purpose of the Study:

  • To investigate the impact of twinning on the achievement of early motor milestones.
  • To compare motor development in twins versus singletons.
  • To examine the influence of sex, zygosity, and birth cohort on twin motor development.

Main Methods:

  • Maternal reports collected data on motor milestones (turn, sit, crawl, stand, walk) in twins aged 0-24 months.
  • Twin data was compared to normative singleton data from Child Health Clinics (CHC).
  • Analyses controlled for gestational age and examined effects of sex, zygosity, and birth cohort.

Main Results:

  • No significant differences were found in motor milestone achievement between twins and singletons.
  • Girls achieved 'sit without support' slightly earlier than boys.
  • Dizygotic (DZ) twins achieved milestones faster than monozygotic (MZ) twins.
  • Twins born in earlier cohorts achieved milestones faster than those in later cohorts.

Conclusions:

  • Twinning does not delay the achievement of motor milestones compared to singletons.
  • Sex has minimal effect on early motor development.
  • DZ twins demonstrate faster motor milestone attainment than MZ twins.
  • Later birth cohorts show delayed gross motor development (crawl, stand, walk).
