Dietary behaviors throughout childhood are associated with adiposity and estimated insulin resistance in early adolescence: a longitudinal study.

ABSTRACT: BACKGROUND:Despite the growing prevalence of excess weight and prediabetes in children, the contributing role of dietary behaviors throughout childhood remains poorly understood. We examined longitudinal associations of dietary behaviors throughout childhood with adiposity and estimated insulin resistance (HOMA-IR) in adolescence. METHODS:Among 995 children from Project Viva, a pre-birth cohort, we examined associations of child dietary behaviors (frequency of eating breakfast, fast food, family dinner, and eating meals while watching television) reported annually throughout childhood (from ages 4 to 11?years) with body mass index z-score (BMI-z; n?=?991), waist circumference (WC; n?=?995), DXA overall and central adiposity measurements (n?=?721), and HOMA-IR (n?=?579) in early adolescence (13.2?±?0.9?years old). We used mixed effects models adjusted for potential confounders. RESULTS:Eating breakfast daily throughout childhood was associated with lower BMI-z and DXA-measured overall and central adiposity in boys and girls (e.g. for whole-body fat %: ? -?1.43% [95% CI: -2.42, -?0.45] and?-?1.47% [-?2.25, -?0.68]), and with lower HOMA-IR in boys (% difference?-?15.6% [-?22.7, -?7.9]). Daily family dinner and eating fast food less than once per week throughout childhood were both associated with lower BMI-z and adiposity in girls (for BMI-z: ? -?0.17?units [-?0.24, -?0.11] and ? -?0.09?units [-?0.17, -?0.02]) and lower insulin resistance in boys (% difference?-?7.3% [-?12.4,-?1.8] and?-?7.6% [-?13.2, -?1.7]). Finally, eating meals while watching television

Project description:BackgroundInconsistent findings have been reported for associations between protein intake and age at menarche. We aimed to investigate the association between intake of protein and protein-containing food groups during childhood with menarche among Iranian girls.MethodsGirls aged 6-18 years who did not experience menarche in the third or fourth examination cycles of the Tehran Lipid and Glucose Study were selected and were followed to the fifth examination cycle. Daily intakes of protein from different animal/plant sources and ten protein-containing food groups were assessed using a food frequency questionnaire at baseline (the third or fourth examination cycles). Occurrence of menarche and its onset age were asked during each examination cycle. Cox proportional hazards regression was used to estimating hazard ratios (HRs) and 95% confidence interval (95%CI) for the occurrence of menarche per one standard deviation (SD) of dietary intakes. Logistic regression was also used to estimate the odds of reaching menarche ≤12 years.ResultsDuring the study, 147(61%) of girls reached menarche, the median age at menarche was 12 years. The adjusted HRs (95% CI) for the occurrence of menarche per one-SD of dietary intakes were 0.68 (0.48, 0.98; p = 0.040) for plant protein and 1.36 (1.01, 1.84; p = 0.042) for animal protein after adjusting for baseline age, BMI Z-score, energy intake, and mother's early menarche and education. Substituting 10-g animal protein with plant protein was associated with a 16% (95%CI: 5-25%; p = 0.006) lower risk of menarche. Dietary intakes of poultry (adjusted HR: 1.35; 95% CIs: 1.00-1.82; p = 0.049) and low-fat dairy (adjusted HR: 1.20; 95%CIs: 0.99-1.46; p = 0.064) were marginally associated with the increased risk of menarche. However, the odds of early menarche was significant only for plant protein (adjusted odds ratio = 0.39; 95% CI: 0.16-0.96; p = 0.040).ConclusionsOur findings indicate that the risk of menarche increases by higher intakes of animal protein and decreases by plant protein. Intakes of poultry and low-fat dairy associate with a higher risk of menarche. The odds of menarche occurrence ≤12 years reduces by higher intakes of plant protein.
