Associations of growth from birth to puberty with blood pressure and lipid profile at ~17.5 years: evidence from Hong Kong's "Children of 1997" birth cohort

Birth conditions nutritional status in childhood associated with cardiometabolic risk factors at 30 years of age: a cohort study

This study aimed to assess the association of birth conditions, nutritional status, and childhood growth with cardiometabolic risk factors at 30 years of age. We also evaluated whether body mass index (BMI) at 30 years mediated the association of weight gain in childhood with cardiometabolic risk factors. This is a prospective cohort study that included all live births in 1982 in hospitals in the city of Pelotas, Rio Grande do Sul State, Brazil, whose families lived in the urban area. Mothers were interviewed at birth, and participants were followed at different ages. For our analyses, we used data on weight and height collected at birth, 2 and 4 years and cardiovascular risk factors at 30 years. Multiple linear regressions were performed to obtain adjusted coefficients and G-formula for mediation analysis. Relative weight gain in childhood, despite the age, was positively related to mean arterial pressure, whereas relative weight gain in late childhood was positively associated with carotid intima-media thickness, pulse wave velocity, triglycerides, non-HDL cholesterol, plasma glucose, and C-reactive protein. BMI in adulthood captured the total effect of relative weight gain in the period between 2 and 4 years on carotid intima-media thickness, triglycerides, non-HDL cholesterol, and C-reactive protein. Our findings reinforce the evidence that rapid relative weight gain after 2 years of age may have long-term consequences on the risk of metabolic and cardiovascular disorders.

Rapid Growth in Malnutrition Children Associated with Higher Systolic Blood Pressure in Adolescent

BACKGROUND: Several studies found that children experiencing rapid growth earlier in life might increase the risk of chronic disease. Cardiovascular disease and hypertension are common risk factors and have been the leading cause of death worldwide. However, studies investigating the effects of rapid growth in early life on blood pressure later in life are limited. AIM: This study aimed to analyze the association between rapid growth after the first 1000 days of life and blood pressure at 17−19 years old. METHODS: We analyzed 17-year follow-up cohort using secondary data from the Indonesian Family Life Survey from the second (1997), third (2000), and fifth wave (2014). The survey was conducted in 13 provinces in Indonesia. No more than 672 children under 2 years old were included in the study. Rapid growth was defined as an alteration in length or height-per-age and weight-per-age z-score, based on WHO Child Growth Standard, on 1997 and 2000 time frame which was greater than 0.67, experienced by children with malnutrition (low birth weight, stunted, underweight, and wasting). Blood pressure was measured three times by an oscillometric method in 2014. In addition, we used a one-way ANOVA (analysis of variance) test to assess the association of rapid growth on systolic blood pressure. RESULTS: Malnutrition children at 0-2-year-old that grow rapidly in length or height, had higher systolic blood pressure than normal children (p = 0.029). In contrast, there was no difference observed in systolic blood pressure in children with malnutrition and children who did not experience rapid growth in weight. CONCLUSIONS: Children who had a history of malnutrition earlier in life (0−23 months) and had rapid growth in length or height after the first 1000 days of life had higher systolic blood pressure than normal children and children with malnutrition who did not grow rapidly.

Prepubertal Dietary and Plasma Phospholipid Fatty Acids Related to Puberty Timing: Longitudinal Cohort and Mendelian Randomization Analyses

Dietary intakes of polyunsaturated, monounsaturated and saturated fatty acids (FAs) have been inconsistently associated with puberty timing. We examined longitudinal associations of prepubertal dietary and plasma phospholipid FAs with several puberty timing traits in boys and girls. In the Avon Longitudinal Study of Parents and Children, prepubertal fat intakes at 3-7.5 years and plasma phospholipid FAs at 7.5 years were measured. Timings of Tanner stage 2 genital or breast development and voice breaking or menarche from repeated reports at 8-17 years, and age at peak height velocity (PHV) from repeated height measurements at 5-20 years were estimated. In linear regression models with adjustment for maternal and infant characteristics, dietary substitution of polyunsaturated FAs for saturated FAs, and higher concentrations of dihomo-γ-linolenic acid (20:3n6) and palmitoleic acid (16:1n7) were associated with earlier timing of puberty traits in girls (n = 3872) but not boys (n = 3654). In Mendelian Randomization models, higher genetically predicted circulating dihomo-γ-linolenic acid was associated with earlier menarche in girls. Based on repeated dietary intake data, objectively measured FAs and genetic causal inference, these findings suggest that dietary and endogenous metabolic pathways that increase plasma dihomo-γ-linolenic acid, an intermediate metabolite of n-6 polyunsaturated FAs, may promote earlier puberty timing in girls.
