Tracking a dietary pattern associated with increased adiposity in childhood and adolescence.

ABSTRACT: Understanding dietary tracking may help to inform interventions to improve dietary intakes and health outcomes. This study investigated how a dietary pattern (DP) associated with increased adiposity in childhood tracked from 7 to 13 years of age, in the Avon Longitudinal Study of Parents and Children (ALSPAC).Three-day food diaries were collected at 7, 10 and 13 years. Reduced rank regression was used to score respondents for an energy-dense, high fat, low fiber DP at each age. Tracking coefficients were estimated for the DP and its key foods using data from 7,027 children.The DP tracking coefficient was 0.48 (95% CI: 0.44-0.52) for boys and 0.38 (95% CI: 0.35-0.41) for girls. Of 10 key food groups, fruit, vegetables, high fiber bread, high fiber breakfast cereals and full fat milk intakes exhibited the strongest tracking, particularly among low consumers. Lower maternal education and greater prepregnancy maternal BMI predicted higher DP z scores and lower fruit and vegetable intakes.A dietary pattern associated with increased adiposity tracks moderately from 7 to 13 years of age in this large UK cohort. Specific groups of families may require additional support to foster lifelong healthy dietary habits in their children.

Project description:Aims/hypothesisThe aim of this work was to examine the associations of average weight and weight velocity in three growth periods from birth through adolescence with type 2 diabetes incidence.MethodsChild participants were selected from a 43 year longitudinal study of American Indians to represent three growth periods: pre-adolescence (birth to ~8 years); early adolescence (~8 to ~13 years); and late adolescence (~13 to ~18 years). Age-, sex- and height-standardised weight z score mean and weight z score velocity (change/year) were computed for each period. Participants were followed for up to 25 years from the end of each growth period until they developed diabetes. Associations of weight z score mean or weight z score velocity with diabetes incidence were determined with sex-, birth date- and maternal diabetes-adjusted Poisson regression models.ResultsAmong 2100 participants representing the pre-adolescence growth period, 1558 representing the early adolescence period and 1418 representing the late adolescence period, there were 290, 315 and 380 incident diabetes cases, respectively. During the first 10 years of follow-up, the diabetes incidence rate ratio (95% CI) was 1.72 (1.40, 2.11)/SD of log10 weight z score mean in pre-adolescence, 2.09 (1.68, 2.60)/SD of log10 weight z score mean in early adolescence and 1.85 (1.58, 2.17)/SD of log10 weight z score mean in late adolescence. The diabetes incidence rate ratio (95% CI) was 1.79 (1.49, 2.17)/SD of log10 weight z score velocity in pre-adolescence, 1.13 (0.91, 1.41)/SD of log10 weight z score velocity in early adolescence and 1.29 (1.09, 1.51)/SD of log10 weight z score velocity in late adolescence. There were strong correlations in the weight z score means and weak correlations in the weight z score velocities between successive periods.Conclusions/interpretationHigher weight and accelerated weight gain in all growth periods associate with increased type 2 diabetes risk. Importantly, higher weight and greater weight velocity during pre-adolescence jointly associate with the highest type 2 diabetes risk. Graphical abstract.
