“…Giles et al reported four distinct BMI Z ‐score trajectories from birth to age 3 years among 557 Australian participants. These four trajectory groups, which were characterized by birth size and postnatal growth in the first 6 months of life, were labeled as “low” (lower BMI Z ‐score at birth and substantial decrease until 6 months), “intermediate” (lower BMI Z ‐score at birth and slight decrease until 6 months), “high” (higher BMI Z ‐score at birth and maintenance until 6 months) and “accelerating” (higher BMI Z ‐score at birth and increase until 6 months).…”

“…Group‐based trajectory modeling enables the data themselves to divide a study population into subgroups that present distinct patterns and to fit its own trajectory models for each of those subgroups . Several studies have applied the group‐based trajectory approach to identify distinct weight gain patterns . However, few studies have examined the association between diverse weight gain trajectory patterns in the first 2 years of life and adiposity levels later in life.…”

Objective To identify distinct body mass index (BMI) percentile trajectories during early childhood and examine adiposity levels in childhood and early adulthood according to the BMI percentile trajectories. Methods Iowa Fluoride Study cohort parents (n=1,093) reported their child’s anthropometric data on average six times between age 0 and 23 months. A subset of the cohort underwent DXA scans at approximately age 8 years (n=495) and again at approximately age 19 years (n=314). Group-based trajectory analysis was conducted to identify distinct BMI percentile trajectories from age 0–23 months. Sex-specific age-adjusted linear regression analyses were conducted to compare fat mass index (FMI) in childhood and early adulthood among subgroups that follow the distinct BMI percentile patterns. Results Four BMI percentile patterns were identified: consistently-low (Group1: 9.8%), increase-in-the-second-year (Group2: 33.7%), increase-in-the-first-year (Group3: 23.9%), and consistently-high (Group4: 32.6%). Compared to Group2 females, Groups 3 and 4 females had higher FMI in childhood and early adulthood (P<0.05). However, no significant difference was found in males. Conclusion Females who experiences a steep increase of BMI percentile in the first year of life, as opposed to a steep increase in the second year of life, may have higher body fat later in life, but not for males.

“…1 -12 Previous studies have identified 3 broad types of trajectories: a majority group with "healthy" BMI throughout childhood, groups who develop BMI in the overweight range at some point during childhood, and those with BMI in the overweight or obese range throughout childhood. 1 -6 Underlying influences on different patterns of BMI development are not well understood, but factors reported to predict childhood BMI trajectories include mother's BMI, 1,3,5,6,8,10,11 smoking during pregnancy, 1,5,6 and sociodemographic background. 1 -5, 12 Previous work suggests that a range of early life factors including infant feeding, diet, physical activity, and family routines are associated with child overweight and obesity.…”

BMI Development and Early Adolescent Psychosocial Well-Being: UK Millennium Cohort Study

BACKGROUND AND OBJECTIVES:The underlying influences on different patterns of BMI development are not well understood, and psychosocial outcomes linked to BMI development have been little investigated. Objectives were to identify BMI developmental trajectories across the first decade of life, examine early life predictors of trajectory membership, and investigate whether being on a particular BMI trajectory is associated with markers of psychosocial well-being.

“…53,54 Latent class growth modeling is one method used recently to distinguish groups of children with biologically distinct growth trajectories and estimate the effects of prenatal and postnatal exposures on the odds of membership in a specific growth trajectory group. 55 Future research could benefit from utilizing these advanced methods of studying early life growth patterns.…”

Relationship between prenatal growth, postnatal growth and childhood obesity: a review

2017

Evidence is accumulating that obesity risks become established early in life. The goal of this systematic review is to assess whether there is evidence that rapid postnatal growth holds different implications for childhood obesity risks for children who experienced different patterns of prenatal growth. We conducted systematic database searches in PubMed and Embase in October 2014 for studies assessing the implications of prenatal and postnatal growth for childhood obesity. The 18 studies meeting inclusion criteria indicated that risks of obesity increased with birthweight; risks of obesity also increased with rapid postnatal growth for children across the birthweight distribution. Fifteen studies indicated that rapid postnatal growth is linearly associated with obesity for children and adolescents of all sizes at birth, with no interaction effect. Three studies reported interaction effects with postnatal growth, conferring additional increased risk of obesity among children and adolescents who were small at birth. Both prenatal and postnatal growth are important risk factors for obesity, and their combined effects should be analyzed further to understand how obesity risks develop early in life.

Growth trajectories in early childhood, their relationship with antenatal and postnatal factors, and development of obesity by age 9 years: results from an Australian birth cohort study

Abstract: Efforts to prevent childhood obesity may need to be embedded within population-wide strategies that also pay attention to healthy weight for women in their reproductive years.
