“…We defined weight at one year as the weight measurement taken by a nurse closest to 12 months of age (range: 11–13 months). Weight measurements are taken according to a standard protocol that includes weighting the unclothed infant on a calibrated scale and documenting the weight with precision of 10 g. These weight data have previously been examined in detail and validated in a study assessing the Israeli infant growth curve 18,19 . Using the 2006 World Health Organization growth standards, 20 we calculated age‐ and sex‐specific weight z ‐scores at birth and age one.…”

Background The global prevalence of childhood obesity has risen dramatically recently. Previous studies found an association between rapid infant weight gain and childhood overweight. Evidence suggests that exposure to high ambient air temperatures during prenatal life and during adulthood is associated with birthweight and obesity respectively. Objective The objective of this study was to examine whether exposure to high ambient temperatures during infancy is associated with rapid infant weight gain in Israel. Methods This is a population‐based historical cohort study using data from the Israeli national public network of maternal and child health clinics between 2008 and 2013. We assessed exposure to ambient temperature in the first year of life using a high‐resolution hybrid spatio‐temporal model and calculated annual mean and minimum temperatures for each infant based on daily mean and minimum temperatures at the community clinic location. We defined rapid infant weight gain as a World Health Organization weight z‐score difference >0.67 between birthweight and weight at age one year. We estimated these associations using log‐linear and general additive models and adjusted for population group, district, maternal age, parental education, parity, sex, gestational age, birthweight, calendar year and calendar month of birth. Results The study population included 217,310 singleton‐term infants. Adjusted models demonstrated a positive association between ambient temperature exposure and rapid infant weight gain. Compared to the third quintile of minimum temperature, infants exposed to the first and second quintile had an adjusted relative risk of 0.98 (95% CI 0.96, 1.00) and 0.97 (95% CI 0.95, 0.98), respectively, while those exposed to the fourth and fifth quintiles had an adjusted relative risk of 1.06 (95% CI 1.04, 1.07) and 1.02 (95% CI 1.00, 1.04) respectively. The associations with mean temperature were similar but slightly weaker. Conclusions Exposure to higher ambient temperatures, of emerging importance in the climate change era, is associated with rapid infant weight gain in Israel. Future studies should use additional exposure, covariate, and outcome data to analyse the nature and the source of this association in more detail.

“…Validated weight measurements were taken by nurses according to a standard protocol that includes weighting the unclothed infant on a calibrated scale and documenting the weight with 10 g precision. 35,36 We evaluated rapid weight gain during infancy using the measurements taken between birth and age fifteen months, to also capture the visits of those late to the age one-year recommended visit (Figure S1 and Table S1). We included all available information, regardless of infants' geographic location or birthweight (N = 1,295,893).…”

BackgroundChildhood overweight and obesity is a global public health problem. Rapid infant weight gain is predictive of childhood overweight. Studies found that exposure to ambient air pollution is associated with childhood overweight, and have linked prenatal exposure to air pollution with rapid infant weight gain.ObjectivesTo examine the association between prenatal and postnatal ambient NO2 exposure, a traffic‐related marker, with rapid weight gain in infants.MethodsWe carried out a population‐based historical cohort study using data from the Israeli national network of maternal and child health clinics. The study included 474,136 infants born at term with birthweight ≥2500 g in 2011–2019 in central Israel. Weekly averages of NO2 concentration throughout pregnancy (prenatal) and the first 4 weeks of life (postnatal) were assessed using an optimized dispersion model and were linked to geocoded home addresses. We modelled weight gain velocity throughout infancy using the SuperImposition by Translation and Rotation (SITAR) method, a mixed‐effects nonlinear model specialized for modelling growth curves, and defined rapid weight gain as the highest velocity tertile. Distributed‐lag models were used to assess critical periods of risk and to measure relative risks for rapid weight gain. Adjustments were made for socioeconomic status, population group, subdistrict, month and year of birth, and the alternate exposure period – prenatal or postnatal.ResultsThe cumulative adjusted relative risk for rapid weight gain of NO2 exposure was 1.02 (95% confidence intereval [CI] 1.00, 1.04) for exposure throughout pregnancy and 1.02 (95% CI 1.01, 1.04) for exposure during the first four postnatal weeks per NO2 interquartile range increase (7.3 ppb). An examination of weekly associations revealed that the critical period of risk for the prenatal exposure was from mid‐pregnancy to birth.ConclusionsPrenatal and postnatal exposures to higher concentrations of traffic‐related air pollution are each independently associated with rapid infant weight gain, a risk factor for childhood overweight and obesity.

“…Differences in neonatal birth weight have also been identified between ethnic groups. Thus the use of a chart adapted to another population may lead to the overdiagnosis of SGA or LGA [12]. For this reason, projects aiming at developing personalized growth charts are undertaken.…”

Background: Growth charts are the primary tools for evaluating neonatal birth weight and length. They help and qualify the neonates as Appropriate for Gestational Age (AGA), Small for Gestational Age (SGA), or Large for Gestational Age (LGA). The most commonly used neonatal charts include Intergrowth-21st, WHO, and Fenton. The aim of the study was to compare the tools used for assessing neonatal birth weight and the incidence of SGA and LGA using the different charts. Methods: Data on 8608 births in the Clinical Department of Obstetrics and Gynecology were compared. We divided the patient population into five gestational age groups. The 10th and 90th percentiles were calculated. The percentage of cases meeting the SGA and LGA criteria was determined. Results: Statistically significant differences between growth charts were identified for each of the groups. The 10th percentile for the study population corresponded to 2970 g for females and 3060 g for males born in the 40th week of gestation. The 90th percentile values were 4030 g and 4120 g. Our analysis showed a statistically significant difference in detection of LGA or SGA between three growth charts and our data both in male (χ 2 (3) = 157.192, p < 0.001, Kramer's V = 0.444) and female newborns (χ 2 (3) = 162.660, p < 0.001, Kramer's V = 0.464). Discussion: Our results confirm that differences exist between growth charts. There is a need for harmonizing growth assessment standards. It is recommended that a growth chart should be developed for the Polish population, which would improve the diagnosis of SGA and LGA.
