Abstract
Background: Childhood represents a critical period of nutritional risk in the programming of later chronic disease. Few longitudinal studies have explored repeated measures of nutrition throughout the first decade of life in relation to preteen cardiometabolic outcomes.
Objectives: This research aimed to explore associations of early feeding practices (human milk exposure and duration and timing of introduction to solids) and childhood dietary quality and inflammatory scores (at 5 and 9-11 y and change during childhood) on preteen cardiometabolic outcomes.
Methods: This is an analysis of children from the ROLO longitudinal birth cohort study (n = 399). Information on early feeding practices were obtained at postnatal study visits. Food frequency questionnaires collected maternal-reported dietary intakes for each child at 5 and 9-11 y of age. Healthy Eating Index (HEI)-2015 and the Children's Dietary Inflammatory Index (C-DII) scores were calculated. Anthropometry, body composition, blood pressure, heart rate, cardiorespiratory endurance, and blood biomarkers were obtained at 9-11 y. Crude and adjusted linear regression models examined nutritional exposure associations with preteen cardiometabolic outcomes.
Results: In the adjusted model, any human milk exposure was associated with lower body fat (%) at 9-11 y (β: -2.86; 95% confidence interval [CI]: -5.46, -0.27; P = 0.03), than never receiving human milk. At 5 y, diet scores were favorably associated with lean mass at 9-11 y (P < 0.05 for both). Higher preteen HEI-2015 scores were associated with lower preteen leptin levels (tertile 3 compared with tertile 1-β: -2.92; 95% CI: -5.64, -0.21; P = 0.03). Diet quality significantly deteriorated (HEI-2015 score decreased) and became more proinflammatory (C-DII score increased) from 5 to 9-11 y of age. Diet quality/inflammation deterioration (compared with improvement) or overall change in dietary scores were not related to preteen cardiometabolic outcomes.
Conclusions: Exposure to human milk in early life was associated with lower preteen adiposity, irrespective of duration. Diet quality/inflammatory potential deteriorated between early childhood and the preteen years, highlighting a potential period for intervention.
期刊介绍:
American Journal of Clinical Nutrition is recognized as the most highly rated peer-reviewed, primary research journal in nutrition and dietetics.It focuses on publishing the latest research on various topics in nutrition, including but not limited to obesity, vitamins and minerals, nutrition and disease, and energy metabolism.
Purpose:
The purpose of AJCN is to:
Publish original research studies relevant to human and clinical nutrition.
Consider well-controlled clinical studies describing scientific mechanisms, efficacy, and safety of dietary interventions in the context of disease prevention or health benefits.
Encourage public health and epidemiologic studies relevant to human nutrition.
Promote innovative investigations of nutritional questions employing epigenetic, genomic, proteomic, and metabolomic approaches.
Include solicited editorials, book reviews, solicited or unsolicited review articles, invited controversy position papers, and letters to the Editor related to prior AJCN articles.
Peer Review Process:
All submitted material with scientific content undergoes peer review by the Editors or their designees before acceptance for publication.
