Is overweight or obesity associated with anemia in children? Follow-up of Samoans in the Ola Tuputupua'e "Growing Up" study.

ABSTRACT:

Objectives

Globally, there is growing evidence of a double burden of malnutrition with obesity coexisting alongside micronutrient deficiencies across the life course. An emergent double burden poses a threat to health during childhood in Samoa: among 2-4-year-olds with overweight/obesity, 42.9% were anemic. Previous research suggests that obesity-related inflammation may increase the risk of iron deficiency or anemia in children. To test this hypothesis, we examined whether overweight/obesity at 2-4 is associated with anemia at 3.8-6 years old among Samoan children.

Methods

Data were obtained from the Ola Tuputupua'e "Growing Up" cohort study. Overweight/obesity at 2-4 years old was classified by body mass index-for-age Z-score > +2 SD. Anemia was defined as hemoglobin < 110 g/L for under 5-year-olds and < 115 g/L for 5-6-year-olds. Prevalence ratios (PRs) for anemia at 3.8-6 years old were estimated by fitting modified Poisson regression models.

Results

In our sample of 197 children, 16.24% (n = 32) were affected by overweight/obesity at 2-4 years old and 26.90% (n = 53) had anemia at 3.8-6 years old. After covariate adjustment, the prevalence of anemia was 18% lower among children with overweight/obesity at 2-4 years old compared to those without (PR:0.82; 95% CI:0.42-1.63); however, the corresponding confidence interval was imprecise and inclusive of a higher prevalence.

Conclusions

There was not strong evidence to support a relationship between overweight/obesity and anemia in Samoan children, suggesting that obesity-related inflammation may not be related to iron deficiency nor anemia in this setting. Further investigation of the antecedents of overweight/obesity and anemia is critical to inform integrated action to improve health in Samoa.

Project description:Background and aims: Youth populations with overweight/obesity (OW/OB) exhibit heterogeneity in cardiometabolic health phenotypes (e.g. fasting glucose, serum triglycerides, etc.). The underling mechanisms for those differences are still unclear. This study aimed to analyze the whole blood transcriptome profile (RNA-seq) of children with metabolic healthy overweight/obesity (MHO) and metabolic unhealthy overweight/obesity (MUO) phenotypes. Methods: 27 children with OW/OB (10.14 ± 1.3 years, 59% boys) from the ActiveBrains project were included. MHO was defined as having none of the following criteria for metabolic syndrome: elevated fasting glucose, high serum triglycerides, low high-density lipoprotein cholesterol, and high systolic or diastolic blood pressure, while MUO was defined as presenting one or more of these criteria. Inflammatory markers interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α), epidermal growth factor (EGF) and, vascular endothelial growth factor A (VEGF) were additionally determined. Total-blood RNA was analyzed by 5’-end RNA sequencing. Two different bioinformatics approaches were performed: 1) Differential gene expression analyses using Limma R/Bioconductor software package (analyses adjusted by sex and maturational status) and 2) weighted gene coexpression network analyses (WGCNA). Results: Children with MHO had lower values of pro-inflammatory cytokines TNF-α and IL-6 compared to MUO (p < 0.05). 40 genes were differentially expressed (FDR < 0.05) in children with MHO compared to MUO. WGCNA analysis identified 23 gene coexpression modules (i.e. clusters of genes) with low preservation (Zsummary < 2) in children with MHO compared to MUO. Differential and WGCNA gene expression patterns identified 32 genes linked to metabolism, mitochondrial and immune functions. Conclusions: Whole blood transcriptome analysis revealed a distinct pattern of gene expression in children with MHO compared to MUO children. The identified gene expression patterns related to metabolism, mitochondrial and immune functions can promote a better understanding of cardiovascular disease prognosis in individuals with MHO.

Project description:BackgroundLeading medical organizations have called on primary care pediatricians to take a central role in the prevention of childhood obesity. Weight counseling typically has not been incorporated into routine pediatric practice due to time and training constraints. Brief interventions with simple behavior change messages are needed to reach high-risk children, particularly Latino and Black children who are disproportionately affected by obesity and related comorbidities. Steps to Growing Up Healthy (Added Value) is a randomized controlled trial testing the efficacy of brief motivational counseling (BMC) delivered by primary care clinicians and the added value of supplementing BMC with monthly contact by community health workers (CHW) in the prevention/reversal of obesity in Latino and Black children ages 2-4 years old.Methods/designMother-child dyads (targeted n = 150) are recruited for this 12-month randomized trial at an inner-city pediatric primary care clinic and randomized to: 1) BMC delivered by clinicians and nurses at well, sick, and WIC visits with the goal of reducing obesogenic behaviors (BMC); 2) BMC plus monthly phone calls by a CHW (BMC + Phone); or 3) BMC plus monthly home visits by a CHW (BMC + Home). During BMC, the medical team facilitates the selection of a specific goal (i.e., reduce sugar sweetened beverage consumption) that is meaningful to the mother and teaches the mother simple behavioral strategies. Monthly contacts with CHWs are designed to identify and overcome barriers to goal progress. Dyads are assessed at baseline and 12 months and the primary outcome is change in the child's BMI percentile. We hypothesize that BMC + Phone and BMC + Home will produce greater reductions in BMI percentiles than BMC alone and that BMC + Home will produce greater reductions in BMI percentiles than BMC + Phone.DiscussionSteps to Growing Up Healthy will provide important information about whether a brief primary care-based intervention that utilizes a motivational interviewing and goal setting approach can be incorporated into routine care and is sufficient to prevent/reverse obesity in young children. The study will also explore whether monthly contact with a community health worker bridges the gap between the clinic and the community and is an effective strategy for promoting obesity prevention in high-risk families.Trial registrationClinicalTrials.gov NCT01973153.
