Rate of weight gain in very-low birth weight Puerto Rican neonates.

ABSTRACT: Small for gestational age neonates have a higher risk of growth delay. The purpose of the study is to determine if there are differences in their early weight gain patterns that persist after adjusting for confounding variables.Two-hundred sixteen neonates born between 1999 and 2003 were included. The group for analysis was derived by matching all the SGA infants with AGA infants by sex, year of birth, and birth weight. The period of observation was from birth to date of discharge. Weight gain rate was defined as grams gained per kilogram of birth weight per day. Two sample T-test was used to determine the difference in growth rate between the groups. Simple regression was used to establish the effect of morbidities on weight gain rate.The total mean birth weight was 1105 g (+/- 223 g), the mean gestational age was 30 weeks (+/- 2.7 weeks), and the mean weight gain rate was 13.4 g/kg/d (+/- 6.8 g/kg/d). The mean weight gain rate for the adequate for gestational age group was lower (11.9 g/kg/d +/- 7.6g versus 14.9 g/kg/d +/- 5.5 g) (P < 0.001). When all variables were analyzed using the lineal regression model, only having a low APGAR score (P = 0.02) and being small for gestational age (P = 0.0004) were significant.We conclude that the growth patterns of very low birth weight neonates are different based on the adequacy of their birth weight, and that the disparity in growth rate is not explained by the differences in the incidence of morbidities that affect growth.

Project description:BackgroundCholestasis is a common but serious clinical condition in preterm neonates. The current management for preterm neonatal cholestasis has limitations. The aim of this study was to determine effects of Bifidobacterium supplementation on the prevention and alleviation of cholestasis in preterm infants with very low birth weight.MethodsPreterm neonates with very low birth weight were enrolled in the Children's Hospital of Soochow University between December 2012 and December 2017. The patients were randomly assigned into Bifidobacterium and control groups, and effects of Bifidobacterium supplementation on the outcomes were compared between the two groups.ResultsThere was no significant difference in the baseline characteristics in the two groups. Notably, the proportion of cases with neonatal cholestasis was significantly lower, with fewer neonatal cholestasis-associated complications in the Bifidobacterium group compared with the control group (6% versus 22%, P < 0.01). Furthermore, the Bifidobacterium group exhibited less severe cholestasis and better improvement of the liver function than the control group as evidenced by the biochemical tests (P < 0.01). Furthermore, the Bifidobacterium group exhibited less severe cholestasis and better improvement of the liver function than the control group as evidenced by the biochemical tests (P < 0.01). Furthermore, the Bifidobacterium group exhibited less severe cholestasis and better improvement of the liver function than the control group as evidenced by the biochemical tests (days, P < 0.01). Furthermore, the Bifidobacterium group exhibited less severe cholestasis and better improvement of the liver function than the control group as evidenced by the biochemical tests (P < 0.01). Furthermore, the Bifidobacterium group exhibited less severe cholestasis and better improvement of the liver function than the control group as evidenced by the biochemical tests (P < 0.01).

Furthermore, the Bifidobacterium group exhibited less severe cholestasis and better improvement of the liver function than the control group as evidenced by the biochemical tests (.ConclusionsBifidobacterium supplementation has significantly preventive and other beneficial effects on the management of cholestasis in preterm infants with very low birth weight. Its long-term safety and effectiveness will need further investigation. This trial is registered with the Chinese Clinical Trial Registry (Registration No. ChiCTR1900022296).

Project description:Background:Excessive gestational weight gain and rapid infancy weight gain (RIWG) are associated with increased susceptibility to childhood obesity. Since low-income and minority children are particularly at risk, investigation of the associations between gestational weight gain and rate of infancy weight gain may inform childhood obesity prevention. This study investigated the associations between gestational weight gain and rate of infancy weight gain during the first four to six months postpartum in participants from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Hawai'i and Puerto Rico. Methods:This was a cross-sectional secondary data analysis from a text message-based intervention in WIC participants in Hawai'i and Puerto Rico. The analysis included 80 mother/infant pairs from the control group who completed the follow-up visit when infants were four to six months old. Maternal weight, height, and gestational weight gain were self-reported. Infant weight was measured at baseline and follow-up. A proportional odds model was used to investigate the association between gestational weight gain and infancy weight gain rate (rapid or extremely rapid, on-track, or slow), adjusting for maternal age, pregravid body mass index (BMI) status, parity, and being up-to-date with infant vaccinations. Results:In comparison to recommended gestational weight gain, excessive and inadequate (under the recommended amount) gestational weight gain was associated with 77% decreased (adjusted odds ratio [AOR]?=?0.23; 95% confidence interval [CI]?=?0.08, 0.70; p?=?0.01) and 71% decreased (AOR?=?0.29; 95% CI?=?0.09, 0.94; p?=?0.04) odds of RIWG versus on-track or slow infant weight gain, respectively. In comparison to women with one child, women with two children (AOR?=?0.31; 95% CI?=?0.11, 0.87; p?=?0.03) or three or four children (AOR?=?0.24; 95% CI?=?0.07, 0.88; p?=?0.03) had significantly lower odds of RIWG versus on-track or slow infancy weight gain. Conclusions:Women with excessive or inadequate gestational weight gain had lower proportional odds of RIWG and were more likely to have slower infant weight gain than women who gained the recommended amount of weight.
