Longitudinal studies demonstrating persistence of adiposity from childhood to adulthood
Study | Baseline year; study size (n); participant age | Follow-up year; study size (n); participant age | Association between childhood obesity and adulthood obesity | Unique data or comments |
---|---|---|---|---|
Follow-up of the Harvard Growth Study12 | 1922–1935; 508; 13–18 years | 1988; 425; 72 ± 1 years | 52% of survivors who were obese in youth remained obese in old age; adolescent BMI predicted adverse outcomes independent of adult BMI | 55 year follow-up; all-cause and CHD mortality in men; weight unknown in subjects deceased at follow-up (32%) |
Bogalusa Heart Study14,17,21,22,24,55 | Multiple; 16,000 overall; 0–17 years | Multiple; variable; Up to 38 years | Baseline BMI and adiposity correlated with adult BMI (r=0.66); 62% in highest childhood BMI quartile persisted to highest BMI quartile in adulthood; highest childhood BMI and age most likely to persist to high adult BMI; even BMI at 2–5 years correlated with adult BMI | NHW and AA, community-based study |
NHLBI Growth and Health Study50 | 1986; 2,379 girls; 9–10 years | 1998–2001; 2,054; yearly until 21–23 years | Overweight girls were 11–30-times more likely to be obese adults; relationship between CVD risk factors and weight already present at 9 years of age | NHW and AA, females; large cohort; good retention |
Minneapolis Children's Blood Pressure Study78 | 1977; 1,207; 7.7 years | 1993–1995; 679; 23.6 years | Childhood and adulthood BMI and weight correlated; childhood weight gain related to adult CVD risk factors | Data on IR |
Cardiovascular Risk in Young Finns Study128,129 | 1980; 3,596; 3–18 years | 2001; 2,283; 24–39 years | Childhood BMI correlated with adult BMI (r=0.45, P<0.0001); obesity persisted from youth to adulthood | Large cohort; good retention; >20 years of follow up |
Muscatine Coronary Risk Factor Project130,131 | 1971; 8,909; 9–18 years | 1981; 2,631; 23, 28, and 33 years | Correlation between child and adult obesity quintiles: r=0.51–0.88 for weight; r=0.58–0.91 for BMI; 49–70% and 48–75% remained in upper quintiles; 31% from upper/lower quintiles changed groups | Population based; 15–24 years of follow up |
Copenhagen Male Draftees Study132 | 1937–1963; 93,800; 7 years | 1988; 1,400; time of military draft | Compared 429 severely obese young adults to 1% random sample of draftees; risk of adult obesity increased exponentially over childhood BMI range | Large population-based cohort; males |
Australian Schools Health and Fitness Survey133 | 1985; 8,498; 7–15 years | 2001–2005; 4,571; 24–34 years | RR=4.7 for obese child to become obese adult; proportion of adult obesity attributed to childhood obesity 6.4% in males and 12.6% in females | Australian cohort |
1958 British Birth Cohort134 | 1958; 17,378; birth | 1965–1991; 11,407; 7, 11, 16, 23, and 33 years | Correlation between child (7 years) and adult (33 years) BMI (r=0.33 male, r=0.37 female), but only 17–18% of obese 33-year-olds had been obese at 7 years. Having two obese parents increased risk of adult obesity | British cohort |
New Delhi Birth Cohort135 | 1969–1972; 2,584; birth | 1998–2002; 1,492; 26–32 years | Greater childhood BMI gain from 5–14 years associated with MetS, IGT, DM, but none obese at 12 years | Indian cohort |
Newton Girls Study136 | 1965; 793, 8–9 years | 1998; 448, 42.1 years | Premenarchal weight status main influence on adult weight status | Longitudinal data on females |
