Aghaee S, Quesenberry CP, Deardorff J, Kushi LH, Greenspan LC, Ferrara A, Kubo A. Associations between infant growth and pubertal onset timing in a multiethnic prospective cohort of girls. BMC Pediatr 2022; 22:171. [PMID: 35361165 PMCID: PMC8969386 DOI: 10.1186/s12887-022-03242-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 03/17/2022] [Indexed: 11/13/2022] Open
Abstract
Background Early puberty increases risk of adverse health conditions throughout the life course. US girls are experiencing earlier puberty without clear reasons. Studies suggest early life factors, such as infant growth, may influence pubertal timing. We assessed the associations between infant growth and onset of breast development (thelarche), pubic hair development (pubarche), and menarche in girls. Methods A prospective cohort of girls born at a Kaiser Permanente Northern California medical facility in 2005–11 was used. Weight-for-age z-scores were calculated at birth and 24 months. Difference in z-scores greater than 0.67 represent rapid “catch-up” growth, less than -0.67 represent delayed “catch-down” growth, and between -0.67 and 0.67 represent “normal” growth. Pubertal onset was measured using clinician-assessed sexual maturity ratings (SMRs) and defined as the age at transition from SMR 1 to SMR 2 + for both thelarche and pubarche. SMR data was collected through June 2020. Menarche was analyzed as a secondary outcome. Weibull and modified Poisson regression models were used. Models were adjusted for potential confounders. Results There were 15,196 girls included in the study. Approximately 30.2% experienced catch-up growth, 25.8% experienced catch-down growth, and 44% had normal growth. Girls with catch-up growth had increased risk of earlier thelarche (hazard ratio = 1.26, 95% confidence interval (CI): 1.18, 1.35), pubarche (1.38, 95% CI: 1.28, 1.48), and menarche (< 12y, relative risk = 1.52, 95% CI: 1.36, 1.69) compared to those with normal growth, after adjusting for covariates. These associations were partially mediated by childhood body mass index. Catch-down growth was associated with later pubertal onset. Conclusions Girls who experience infant catch-up growth have higher risk of earlier pubertal development compared to girls with normal growth and the associations are partially explained by childhood obesity. This information may help clinicians to monitor girls who are at high risk of developing earlier.

Van Minde MRC, Lagendijk J, Raat H, Steegers EAP, de Kroon MLA. An innovative postnatal risk assessment and corresponding care pathways in Preventive Child Healthcare. J Adv Nurs 2021; 78:739-749. [PMID: 34590735 PMCID: PMC9293120 DOI: 10.1111/jan.15003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 06/12/2021] [Accepted: 07/24/2021] [Indexed: 11/29/2022]
Abstract
Aims This study aims to evaluate the effectiveness of an innovative postnatal risk assessment (the postnatal Rotterdam Reproductive Risk Reduction checklist: R4U) and corresponding care pathways in Preventive Child Healthcare (PCHC), along with PCHC professional satisfaction. Design Four PCHC organizations located in three municipalities with a higher adverse perinatal outcome than the national average were selected for participation. The study concerns a historically controlled study design. Methods The study enrolled participants from September 2016 until December 2017. The historical cohort existed of children born in previous years from 2008 until 2016. The outcome measure was defined as catch‐up growth: more than 0.67 standard deviation score weight for height increase in the first 6 months of life. PCHC professional opinion was assessed with a digital survey. Results After the inclusion period, 1,953 children were included in the intervention cohort and 7,436 children in the historical cohort. Catch‐up growth was significantly less common in the intervention cohort; 14.9% versus 19.5% in the historical cohort (p < 0.001). A regression sensitivity analysis, using matching, showed an odds ratio of 0.957 (95% CI 0.938–0.976) for the intervention cohort. In the survey, 74 PCHC physicians and nurses participated; most of them were neutral concerning the benefits of the postnatal R4U. Conclusion This study shows that the implementation of a novel postnatal risk assessment including in PCHC is feasible and effective. Final efforts to ensure a widespread implementation should be taken. Impact PCHC offers a unique opportunity to recognize and address risk factors for growth and development in children and to implement care pathways. Effective and widely implemented risk assessments in antenatal and PCHC are scarce. To our knowledge, this kind of evidence‐based postnatal risk assessment has not been implemented in PCHC before and seizes the opportunity to prevent catch‐up growth and its long‐term effects.

Abstract
OBJECTIVE Maternal nutrition during pregnancy is a key factor influencing birth outcome. Dietary diversity is a proxy for multiple macro- and/or micronutrient sufficiency of an individual's diet. This systematic review aimed to summarise the findings on the association between maternal dietary diversity during pregnancy and the risk of low birth weight (LBW) in newborns. DESIGN This is a systematic review study. SETTING Google and the PubMed, Scopus and Google Scholar databases were searched to extract original studies on humans published until June 2020, without date restrictions. There was no limitation regarding geographic region or economic condition of countries. Duplicated and irrelevant studies were screened out and data were obtained through critical analysis. PARTICIPANTS Articles that examined the association between maternal dietary diversity during pregnancy and the risk of LBW in infants were included. RESULTS Of the ninety-eight studies retrieved, fifteen articles were included in the final review. All included articles represent low- and middle-income countries. Eighty percentage of the studies (n 12) indicated that low maternal dietary diversity during pregnancy is associated with an increased risk of LBW infants. Three studies that included a small number of LBW infants and did not take into account factors which may bias study results failed to show this association. CONCLUSION The results suggest that low maternal dietary diversity during pregnancy may be associated with the risk of LBW, more specifically in developing countries. Dietary diversity might be a valuable predictor of maternal nutrition during pregnancy and the chance of giving birth to a LBW infant.

Abstract
Background Accelerated postnatal growth is an important predictor for obesity risk. It is unknown whether early-life obesity-related risk factors affect body mass index (BMI) growth rates during distinct growth periods from early infancy through preschool years. Objective We examined whether breastfeeding duration, maternal BMI, and birth weight are associated with growth trajectories of age- and sex-standardized WHO BMI z scores (zBMIs) in young children. Design Children (n = 5905) in The Applied Research Group for Kids (TARGet Kids!) prospective cohort study underwent repeated measures of weight and length or height from birth to 10 y of age. Piecewise linear mixed models were used to determine whether zBMI growth rates differ for each risk factor during periods of growth between birth and 1, 3, 18, 36, and 72 mo of age. Results Children who were breastfed <6 mo compared with ≥6 mo showed a higher growth rate between 1-3 and 3-18 mo, resulting in higher standardized BMIs (zBMIs) of +0.24, +0.12, and +0.19 at 18, 36, and 72 mo, respectively. Maternal BMI (in kg/m2) ≥30 compared with <30 resulted in higher growth rates between 1-3 and 36-72 mo and higher zBMIs of +0.22, +0.14, +0.18, and +0.41 at 3, 18, 36, and 72 mo, respectively. Infants weighing <2.5 kg at birth (compared with 2.5-4 kg) experienced higher growth rates between 1-3 and 3-18 mo but had lower zBMIs at all time points (zBMI: -1.45 to -0.21). Infants weighing ≥4 kg at birth (compared with 2.5-4 kg) had significantly lower growth rates in the first 3 mo but higher zBMIs at all time points (zBMI: +1.16 to +0.27). Conclusion Differences in zBMI growth rates by breastfeeding duration, maternal BMI, and birth weight are seen in early infancy and contribute to differences in zBMI, which persist into midchildhood. This trial was registered at www.clinicaltrials.gov as NCT01869530.

Abstract
Purpose To evaluate a comprehensive scoring system which combines clinical manifestations of Pierre Robin Sequence (PRS) including severity of breathing difficulties, body weight and preoperative Cormack-Lehane grade, for its correlation with perioperative PRS airway management decision. Design Forty PRS children were retrospectively recruited after surgery. Specialists examined all subjects and scored for clinical manifestations (1´ - 4´), weight gain (1´- 4´), dyspnea scores (1´- 4´), and Cormack-Lehane grade (1´- 4´). The correlation of the integrated scores and the necessity of endotracheal intubation or laryngeal mask application were analyzed. In addition, the score correlation with postoperative dyspnea and/or low pulse oxygen saturation (SPO2) levels after extubation was determined. Findings In our study every individual patient had a score from 0´ to 16´, while the higher in the numbers represented higher risk of breathing difficulty. All patients with comprehensive scores <10 points underwent endotracheal intubation successfully. Patients scoring 10–12 points had an intubation success rate of 47%, whereas all patients scored >13 points required a laryngeal mask assisted airway management and were considered to have difficult airways. Dyspnea after extubation and postoperative low SPO2 occurred among patients who scored over 10 points. Conclusion In PRS patients, preoperative weight gaining status and severity of dyspnea in combination with Cormack-Lehane classification provide a scoring system that could help to optimize airway management decisions such as endotracheal intubation or laryngeal mask airway placement and has the potential to predict postoperative dyspnea or low SPO2 levels.

Abstract
BACKGROUND Although the immutable benefits of breastfeeding are well documented, information on the potential consequences of exposure to tobacco metabolites specifically via breastfeeding is sparse. OBJECTIVE The aim was to conduct the first study of the association between exposure to tobacco metabolites specifically through breastfeeding and infant weight gain. METHODS We used historical data from the US Collaborative Perinatal Project. Mothers were classified as nonsmokers, light smokers (1-19 cigarettes/day), and heavy (20+ cigarettes/day) smokers. In-hospital feeding type was observed during a nursery stay after delivery. We conducted stratified analyses among average-for-gestational-age (AGA; N = 23 571) and small-for-gestational-age (SGA; N = 2552) infants. We isolated the effect of exposure to tobacco metabolites specifically through breastfeeding. RESULTS Overall, maternal smoking was associated with change in weight-for-length z-score in a dose-response manner. Change in weight z-score was most pronounced among SGA infants of heavy smokers (breastfed: 0.53; 95% confidence interval [CI], 0.12-0.94; formula fed: 0.17; 95% CI, 0.03-0.30). Exposure to tobacco metabolites specifically through breastfeeding was not associated with additional weight gain among AGA infants. Among the much smaller sample of SGA infants, exposure specifically through breastfeeding was associated with marginally significant additional weight gain (0.46; 95% CI, 0.00-0.91) among infants of heavy smokers. CONCLUSION Our findings are in accord with recommendations by health agencies for smokers to breastfeed. However, SGA infants exposed to tobacco metabolites via breastfeeding by heavy smokers appear to gain weight more rapidly than other infants. Practical implications of our findings are discussed.

Abstract
Hypertension is a predominant risk factor for cardiovascular diseases and a major health care burden. Accumulating epidemiological and experimental evidence suggest that adult-onset hypertension may have its origins during early development. Upon exposure to glucocorticoids, the fetus develops hypertension, and the offspring may be programmed to continue the hypertensive trajectory into adulthood. Elevated oxidative stress and deranged nitric oxide system are not only hallmarks of adult hypertension but are also observed earlier in life. Endothelial dysfunction and remodeling of the vasculature, which are robustly associated with increased incidence of hypertension, are likely to have been pre-programmed during fetal life. Apparently, genomic, non-genomic, and epigenomic factors play a significant role in the development of hypertension, including glucocorticoid-driven effects on blood pressure. In this review, we discuss the involvement of the aforementioned participants in the pathophysiology of hypertension and suggest therapeutic opportunities for targeting epigenome modifiers, potentially for personalized medicine.

Abstract
ABSTRACT The aim of this study was to analyze the concept of child growth by identifying the attributes and consequences that make up the phenomenon. The concept analysis was supported by 41 studies and based on the evolutionary analysis model and integrative literature review. Five databases, Scopus, CINAHL, LILACS, PubMed, and the Cochrane Library were searched to select articles. The search found that growth has presented different connotations, including social and physiological aspects, which are part of the physical domain of child development. Attributes, antecedents, and consequences identified provide an overview of the phenomenon analyzed, because these point out several aspects previously related to other studies on child growth. The theoretical understanding about child growth can offer nurses in-depth knowledge about factors involved in this process, facilitating intervention-based decision-making.

Abstract
The 'fetal origin hypothesis' suggests that metabolic diseases are directly related to poor nutritional status in early life. Thus, a high birth weight (HBW) may pose a lower risk than normal birth weight. Overweight and overnutrition are among the most widely recognized risk factors of metabolic diseases. To explore the possible effects of HBW on blood pressure and hypertension, a systematic review was performed. The PubMed and Embase databases were searched for relevant studies. The outcomes included systolic blood pressure (SBP), diastolic blood pressure (DBP) and hypertension. We included all of the studies that assessed the differences in outcomes for children aged >1 year between those born with normal birth weight (birth weight between 2500 and 4000 g or between the 10th and 90th percentiles for their gestational age) and those born with HBW (birth weight4000 g or 90th percentile for their gestational age). The outcomes were analyzed descriptively and by conducting a meta-analysis. Thirty-one studies satisfied the inclusion criteria. The mean difference in blood pressure and the relative risk of hypertension between individuals with HBW and individuals with normal birth weight was inversely associated with age. SBP and DBP, as well as the prevalence of hypertension, were higher in younger children with HBW but lower in older adults with HBW compared with individuals with normal birth weight. The findings suggested that an individual with HBW is prone to hypertension and higher blood pressure during childhood. However, a 'catch-down' effect in the elevation of blood pressure is observed in subjects with HBW as they grow older. Thus, older individuals with HBW are less susceptible to hypertension than those with normal birth weight.

Abstract
Weight-for-length during the early postnatal period is a critical predictor of subsequent body composition and metabolic risk. This study was designed to analyze change in weight-for-length status according to birth weight in early infancy. Data were collected for 267 infants enrolled in the Jackson County Women, Infants, and Children (WIC) program. Postnatal measurements were collected at a clinic visit between birth and 12 weeks of age (mean = 5.7 weeks). Changes in WHO z-scores (weight, length, weight-for-length) between birth and the clinic visit were calculated. Infants were classified as exclusively breastfed or as formula-fed. Ethnicity was coded as Hispanic or non-Hispanic. Infants were classified based on birth weight z-score as lower (<-1 SD) or higher (> +1 SD). Multiple regression models tested birth weight, demographic factors, and feeding as predictors of z-score change measures. Demographic factors and feeding were also tested as moderators of the effects of birth weight. Lower birth weight infants displayed an increase in weight-for-length z-score between birth and the clinic visit. Change in weight-for-length was associated with significant increase in weight z-score but not in length z-score. Higher birth weight predicted decrease in weight and length z-scores but did not predict change in weight-for-length. Hispanic ethnicity predicted decrease in length z-score and increase in weight-for-length z-score but did not moderate effects of birth weight. Increase in weight-for-length among lower birth weight infants and persistence of high weight-for-length among higher birth weight infants may reflect phenotypic adjustments that are maladaptive in adverse dietary environments.

Abstract
OBJECTIVE To determine the pattern and predictors of growth velocity in early infancy in a resource-poor setting. METHODS Weight velocity between birth and first postnatal visit was determined in a cohort of preterm and full-term infants in Lagos, Nigeria using three mathematical methods reported in the literature. Maternal and infant factors predictive of weight velocity were identified by multiple linear regression analysis. RESULTS Overall, 658 infants were enrolled with mean gestational age of 37.7±2.0 weeks, birthweight of 3.2±0.6 kg and median age of 45 (interquartile range: 42-48) days at follow-up. Offspring of older and HIV-positive mothers had significantly lower mean weight velocities while male infants and those with low birthweight and fetal growth restriction had significantly higher mean weight velocity than their peers. These patterns were consistent across the three growth models. Maternal age (p=0.004), antenatal care (p=0.007), HIV-status (p=0.008) and gender (p<0.001) were predictive of weight velocity. Higher weight velocity was strongly associated with lower birthweight (p<0.001) indicative of "catch-up" growth as well as with higher gestational age (p<0.001). CONCLUSIONS While maternal status is predictive of early growth faltering, preterm infants warrant timely intervention to forestall/minimise the potential health and developmental consequences associated with their sub-optimal growth trajectory.

Abstract
BACKGROUND Changes in fish-eating habits due to rapid urbanization in Western Amazon was used as model to investigate whether maternal fish-intake rate impacts on children's weight and height during the first 5 years. AIM The study examined the growth of 82 breastfed children, and maternal fish consumption (hair mercury concentrations, HHg) during pregnancy and lactation. SUBJECTS AND METHODS Fish consumption in mothers and children was estimated through HHg. The children were measured and weighed at birth and at 6 (exclusive breastfeeding), 36 and 60 months. RESULTS Fish consumption rate (HHg) had no significant impact on children's growth at the specified ages (p = 0.35). After 6 months of exclusive breastfeeding, children had the highest proportion of Z-scores <-1 SD; however, weaning (with extended breastfeeding) had a substantial impact in moving up the attained growth at 3 years. The duration of breastfeeding was significantly correlated with attained Z-scores for weight-for-age (r = 0.26; p = 0.02) and weight-for-height (r = 0.22; p = 0.04) but not for height-for-age. At 3 years most children had improved Z-scores (>-1 SD) for height-for-age (70/82), weight-for-age (74/82) and weight-for-height (74/82). At 5 years, all but one child attained Z-scores >-1. CONCLUSION The apparently good nutritional status of subjects is more likely due to a well balanced diet composition than to only one dietary protein source--fish.
