How Has the Age-Related Process of Overweight or Obesity Development Changed over Time? Co-ordinated Analyses of Individual Participant Data from Five United Kingdom Birth Cohorts

Abstract: BackgroundThere is a paucity of information on secular trends in the age-related process by which people develop overweight or obesity. Utilizing longitudinal data in the United Kingdom birth cohort studies, we investigated shifts over the past nearly 70 years in the distribution of body mass index (BMI) and development of overweight or obesity across childhood and adulthood.Methods and FindingsThe sample comprised 56,632 participants with 273,843 BMI observations in the 1946 Medical Research Council National … Show more

“…Within trajectories, males had lower BMI than females at the 10-year baseline in the AYAO and normative classes, although a higher baseline BMI in the COP trajectory. These findings are consistent with clinical and epidemiological observations that girls gain more weight during puberty 21. It also suggests that while boys are at lower risk of early-onset obesity, those who are in this trajectory have a higher BMI.…”

“…MCS has been used to update the historical picture on such phenomena as the shortening of mothers' employment breaks (Hansen, Hawkes & Joshi, 2009), the marginalisation of social tenants (Feinstein et al, 2008) and increased child adiposity (Johnson, Li, Kuh & Hardy, 2015) across all four national cohorts. Comparing MCS with the second generation studies of the 1958 and 1970 cohorts, whose offspring were surveyed in 1991 and 2004, showed that the social gradient in child development (vocabulary and total difficulties scores) had not widened since the early 1990s (Blanden & Machin, 2008).…”

“…In the UK, we have previously demonstrated a secular trend towards higher body mass index (BMI) at increasingly younger ages, such that, by adolescence, overweight/obesity prevalence is already two to three times higher in cohorts born into, compared with before, the obesity epidemic 2. This is particularly concerning given evidence that adolescent obesity tracks into and across adulthood and is associated with the development of various non-communicable disease risk factors 3–6…”
