[PMID: 35081112 PMCID: PMC8791492 DOI: 10.1371/journal.pone.0260703] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Accepted: 11/15/2021] [Indexed: 11/24/2022] Open
Abstract
Both cardiovascular and reproductive complications may have origins in utero or in early life. Women in the Bogalusa Heart Study (n = 1401) had been linked to birth certificates for birthweight and gestational data, which were examined relative to childhood (ages 4–16) cardiometabolic indicators, indicated by mean levels overall and total risk factor burden as estimated by area under the curve (AUC) computed from longitudinal quadratic random-effects growth models. Women reported the birthweight and gestational age of each of their own pregnancies, and delivery medical records were linked to interview data where possible. Path analyses were conducted to examine the relationships among a woman’s own birth outcomes, childhood and preconception adult cardiovascular health, and birth outcomes. Mean blood pressure (systolic blood pressure (SBP) adjusted relative risk (aRR) per 1-SD increase, 1.27, 95% CI 1.04–1.57) and low-density lipoprotein (aRR 1.21, 95% CI 1.02–1.44) in childhood predicted preterm birth (PTB), while mean SBP (aRR 1.33, 95% CI 1.02–1.74) predicted term low birthweight. The AUC data suggested an association between blood pressure and PTB (aRR for SBP top 10%, 1.86, 95% CI 1.08–3.21). Pre-pregnancy total cholesterol was negatively associated with gestational age. In path analyses, positive associations were found for each step between own birthweight, childhood BMI, pre-pregnancy BMI, and child’s birthweight. Childhood levels of some, though not all, cardiovascular risk factors may predict adverse birth outcomes (preterm birth and reduced fetal growth).

Abstract
OBJECTIVE To conduct a comprehensive review of the literature on childhood risk factors and their associations with adulthood subclinical and clinical cardiovascular disease (CVD). STUDY DESIGN A systematic search was performed using the MEDLINE, EMBASE, PsycINFO, CINAHL, and Web of Science databases to identify English-language articles published through June 2018. Articles were included if they were longitudinal studies in community-based populations, the primary exposure occurred during childhood, and the primary outcome was either a measure of subclinical CVD or a clinical CVD event occurring in adulthood. Two independent reviewers screened determined whether eligibility criteria were met. RESULTS There were 210 articles that met the predefined criteria. The greatest number of publications examined associations of clinical risk factors, including childhood adiposity, blood pressure, and cholesterol, with the development of adult CVD. Few studies examined childhood lifestyle factors including diet quality, physical activity, and tobacco exposure. Domains of risk beyond "traditional" cardiovascular risk factors, such as childhood psychosocial adversity, seemed to have strong published associations with the development of CVD. CONCLUSIONS Although the evidence was fairly consistent in direction and magnitude for exposures such as childhood adiposity, hypertension, and hyperlipidemia, significant gaps remain in the understanding of how childhood health and behaviors translate to the risk of adulthood CVD, particularly in lesser studied exposures like glycemic indicators, physical activity, diet quality, very early life course exposure, and population subgroups.

Abstract
The study aimed to identify maternal factors associated with birth weight in Colombia from 2002 to 2011. This was a descriptive study based on data from the Live Birth Registry of Colombia, Administrative Department of Vital Statistics. Birth weight was classified as low birth weight < 2,500g, insufficient birth weight 2,500-2,999g, normal birth weight 3,000-3,999g, and high birth weight ≥ 4,000g. Data analysis used Mann-Whitney U test, Kruskal-Wallis test, and multinomial logistic regression. Women with increased likelihood of low birth weight newborns were 35 years or older (OR = 1.4; 95%CI: 1.39-1.4), had little schooling (OR = 1.1; 95%CI: 1.1-1.1), were single (OR = 1.1; 95%CI: 1.1-1.2), without prenatal care (OR = 1.9; 95%CI: 1.9-2.0), and lived in rural areas (OR = 1.2; 95%CI: 1.1-1.2). Women with higher prevalence of high birth weight newborns were 35 years or older (OR = 1.1; 95%CI: 1.1-1.1) and had four or more children (OR = 2.1; 95%CI 2.0-2.1). Insufficient birth weight showed a similar pattern to low birth weight. In conclusion, social, demographic, and maternal factors influence the birth weight of newborns in Colombia.

IUGR with infantile overnutrition programs an insulin-resistant phenotype through DNA methylation of peroxisome proliferator-activated receptor-γ coactivator-1α in rats. Pediatr Res 2015; 77:625-32. [PMID: 25675425 DOI: 10.1038/pr.2015.32] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2014] [Accepted: 11/05/2014] [Indexed: 12/26/2022]
Abstract
BACKGROUND Intrauterine growth restriction (IUGR) followed by postnatal accelerated growth (CG-IUGR) is associated with long-term adverse metabolic consequences, and an involvement of epigenetic dysregulation has been implicated. Peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) is a key orchestrator in energy homeostasis. We hypothesized that CG-IUGR programed an insulin-resistant phenotype through the alteration in DNA methylation and transcriptional activity of PGC-1α. METHODS A CG-IUGR rat model was adopted using maternal gestational nutritional restriction followed by infantile overnutrition achieved by reducing the litter size. The DNA methylation was determined by pyrosequencing. The mRNA expression and mitochondrial content were assessed by real-time PCR. The insulin-signaling protein expression was evaluated by western blotting. RESULTS Compared with controls, the CG-IUGR rats showed an increase in the DNA methylation of specific CpG sites in PGC-1α, and a decrease in the transcriptional activity of PGC-1α, mitochondrial content, protein level of PI3K and phosphorylated-Akt2 in liver and muscle tissues. The methylation of specific CpG sites in PGC-1α was positively correlated with fasting insulin concentration. CONCLUSION IUGR followed by infantile overnutrition programs an insulin-resistant phenotype, possibly through the alteration in DNA methylation and transcriptional activity of PGC-1α. The genetic and epigenetic modifications of PGC-1α provide a potential mechanism linking early-life nutrition insult to long-term metabolic disease susceptibilities.

Abstract
Background: It is now widely accepted that the early-life nutritional environment is important in determining susceptibility to metabolic diseases. In particular, intra-uterine growth restriction followed by accelerated postnatal growth is associated with an increased risk of obesity, type-2 diabetes and other features of the metabolic syndrome. The mechanisms underlying these observations are not fully understood. Aim: Using a well-established maternal protein-restriction rodent model, our aim was to determine if exposure to mismatched nutrition in early-life programmes adipose tissue structure and function, and expression of key components of the insulin-signalling pathway. Methods: Offspring of dams fed a low-protein (8%) diet during pregnancy were suckled by control (20%)-fed dams to drive catch-up growth. This ‘recuperated' group was compared with offspring of dams fed a 20% protein diet during pregnancy and lactation (control group). Epididymal adipose tissue from 22-day and 3-month-old control and recuperated male rats was studied using histological analysis. Expression and phosphorylation of insulin-signalling proteins and gene expression were assessed by western blotting and reverse-transcriptase PCR, respectively. Results: Recuperated offspring at both ages had larger adipocytes (P<0.001). Fasting serum glucose, insulin and leptin levels were comparable between groups but increased with age. Recuperated offspring had reduced expression of IRS-1 (P<0.01) and PI3K p110β (P<0.001) in adipose tissue. In adult recuperated rats, Akt phosphorylation (P<0.01) and protein levels of Akt-2 (P<0.01) were also reduced. Messenger RNA expression levels of these proteins were not different, indicating a post-transcriptional effect. Conclusion: Early-life nutrition programmes alterations in adipocyte cell size and impairs the protein expression of several insulin-signalling proteins through post-transcriptional mechanisms. These indices may represent early markers of insulin resistance and metabolic disease risk.

Abstract
Piglets with intrauterine growth retardation (IUGR) or with normal birth weight (NBW) were selected to evaluate the effects of maternal folic acid supplementation on hepatic mitochondrial function and expression levels of genes involved in mitochondrial DNA (mtDNA) biogenesis and mitochondrial function. During gestation, primiparous Yorkshire sows were fed a Control diet (folic acid 1.3 mg/kg) or a folic acid-supplemented diet (folic acid 30 mg/kg) with 16 replicates per diet. During the 28-d lactation period, sows were fed a common diet. Compared with NBW piglets, hepatic ATP concentrations and mtDNA contents were decreased in IUGR piglets. Furthermore, IUGR piglets exhibited lower membrane potential and decreased oxygen consumption in liver mitochondria, but these parameters were not affected by maternal folic acid supplementation. Intrauterine growth retardation decreased mRNA expression abundance of peroxisomal proliferator-activated receptor-γ coactivator-1α, mitochondrial transcription factor A, uncoupling protein 3, and cytochrome c oxidase subunit I and IV. Impaired antioxidant capacity characterised by increased malondialdehyde content and decreased manganese-superoxide dismutase activity was also observed in IUGR pigs. In IUGR piglets, however, nearly all of these parameters were normalised to the level of NBW piglets when the maternal diet was supplemented with folic acid during pregnancy. Hence, maternal folic acid supplementation was proved to be an effective way to reverse the changes in gene expressions in IUGR pigs, which provided a possible nutritional strategy to improve growth development of IUGR individuals.

Abstract
BACKGROUND This birth cohort study was conducted to investigate the contribution of prenatal and antenatal environmental exposures to later-life hypertensive status. METHODS Two thousand five hundred and three individuals born in 1921-1954 at the Peking Union Medical College Hospital (PUMCH) were targeted; 2,081 (83.1%) participated. Clinical examinations included an interview, blood pressure (BP) measurements, and laboratory assays. Statistical analyses were performed using ordinal regression models with later-life hypertensive status as the dependent variable. Similar analyses were for subpopulations divided by family history of hypertension. RESULTS In the 2,081 subjects, 449 were normotensive, 531 were prehypertensive, and 1,101 had hypertension. Three hundred and forty two hypertensive patients were classified as high-risk (BP ≥180/110 mm Hg, or accompanied with diabetes or three well-established cardiovascular risk factors); the other 759 patients were at mid-to-low risks. Lower birth weight (<2,500 g: odds ratio (OR) = 1.67, P = 0.02; 2,500- <3,000 g: OR = 1.64, P < 0.01; 3,000- <3,500 g, OR = 1.40, P = 0.01), family history of hypertension (OR = 1.73, P < 0.01), poor education (OR = 1.76, P < 0.01), and alcoholism (OR = 3.05, P < 0.01) significantly predicted later-life high-risk hypertension. For participants with hypertensive family history (57.7%), the association with birth weight became nonsignificant, but poor education (OR = 2.33, P < 0.01) and alcoholism (OR = 3.10, P = 0.01) remained important. For participants without hypertensive family history (42.3%), the effects of lower birth weight (<2,500 g: OR = 2.26, P = 0.02; 2,500- <3,000 g: OR = 1.91, P = 0.01; 3,000- <3,500 g, OR = 1.78, P = 0.01) and alcoholism (OR = 3.23, P < 0.01) remained significant. CONCLUSION Low birth weight, low education, alcoholism, and hypertensive family history are linked to later-life hypertensive status. Low birth weight is also partly associated with one's genetic background; whereas the association with education and alcoholism are independent from hypertensive family history.

Abstract
BACKGROUND Both low birth weight, an indicator of intrauterine growth restriction, and low grade systemic inflammation depicted by high sensitivity C-reactive protein (hs-CRP) have emerged as independent predictors of cardiovascular (CV) disease and type 2 diabetes. However, information linking low birth weight and hs-CRP in a biracial (black/white) population is scant. We assessed a cohort of 776 black and white subjects (28% black, 43% male) aged 24-43 years (mean 36.1 years) enrolled in the Bogalusa Heart Study with regard to birth weight and gestational age data were retrieved from Louisiana State Public Health Office. FINDINGS Black subjects had significantly lower birth weight than white subjects (3.145 kg vs 3.441 kg, p < 0.0001) and higher hs-CRP level (3.29 mg/L vs 2.57 mg/L, p = 0.011). After adjusting for sex, age, body mass index (BMI), smoking status and race (for total sample), the hs-CRP level decreased across quartiles of increasing birth weight in white subjects (p = 0.001) and the combined sample (p = 0.002). Adjusting for sex, age, BMI, smoking status and race for the total sample in a multivariate regression model, low birth weight was retained as an independent predictor variable for higher hs-CRP levels in white subjects (p = 0.004) and the total sample (p = 0.007). Conversely, the area under the receiver operative curve (c statistic) analysis adjusted for race, sex, age, smoking status and BMI yielded a value of 0.777 with regard to the discriminating value of hs-CRP for predicting low birth weight. CONCLUSIONS The deleterious effect of low birth weight on systemic inflammation depicted by the hs-CRP levels in asymptomatic younger adults may potentially link fetal growth retardation, CV disease and diabetes, with important health implications.

Abstract
OBJECTIVE It is recognized that there is a remarkable variability in the systemic response to high-fat (HF) diets that cannot be completely explained by genetic factors. In addition, pregnancy complications leading to intrauterine growth restriction (IUGR) have been associated with an increased risk of developing metabolic syndrome (MetS) later in life. Thus, we hypothesized that offspring born with IUGR exhibit permanent metabolic changes that make them more susceptible to HF diet-induced MetS. RESEARCH DESIGN AND METHODS SD rats born normal (control) or with hypoxia-induced IUGR were randomized to low-fat (10% fat) or HF (45% fat) diets. After 9 weeks of feeding, physiological and molecular pathways involved in the MetS were evaluated. RESULTS IUGR offspring exhibited decreased energy intake and physical activity relative to controls. In offspring fed a HF diet, IUGR was associated with decreased total body fat content, a relative increase in intra-abdominal fat deposition and adipocyte size, an increase in fasting plasma concentrations of leptin, triglyceride and free fatty acids, and an increased concentration of triglycerides and ceramides in both liver and skeletal muscle. These changes in lipid homeostasis were accompanied by in vivo insulin resistance and impaired glucose tolerance and associated with increased phosphorylation of protein kinase C , inhibition of insulin receptor substrate 1, and a decreased activation of protein kinase B (PKB; also known as Akt) in liver and skeletal muscle in response to insulin. CONCLUSIONS IUGR enhances specific deleterious metabolic responses to a HF diet. Our results suggest that offspring born with IUGR may require special attention and follow-up to prevent the early onset of MetS.
