Background. Although available evidence suggests short birth intervals are associated with adverse perinatal outcomes, little is known about the extent to which birth spacing affects postnatal child growth. The present study assessed the independent association of birth interval with birth weight and subsequent postnatal growth indices. Methods. This retrospective cohort study carried out in the rural areas of Kassena-Nankana district of Ghana compared postnatal growth across different categories of birth intervals. Birth intervals were calculated as month difference between consecutive births of a woman. The study population comprised 530 postpartum women who had delivered a live baby in the past 24 months prior to the study. Results. Using the analysis of covariance (ANCOVA) that adjusted for age of the child, gender of the child, weight-for-length z-score (WLZ), birth weight, adequacy of antenatal care (ANC) attendance, and dietary diversity of the child, the mean length-for-age z-score (LAZ) among children of short preceding birth interval (<24 months) was significantly higher than among children of long birth interval (that is, at least 24 months) ((0.51 versus −0.04) (95% CI: 0.24–0.87), p  = 0.001). The adjusted mean birth weight of children born to mothers of longer birth interval was 74.0 g more than children born to mothers of shorter birth interval (CI: 5.89–142.0, p < 0.03). Conclusions. The results suggest that a short birth interval is associated positively with an increased risk of low birth weight (an indicator of foetal growth), but birth spacing is associated negatively with the LAZ (an indicator of postnatal growth).

The associations between birth interval and a range of child health outcomes were examined in a population-based cohort of approximately 3500 urban Brazilian children. The effects of several socioeconomic and maternal confounding factors were controlled for in the analyses. Children born after shorter birth intervals (&lt;18 and 18 through 23 months) were disadvantaged with respect to most of the health outcomes when compared with children born after intermediate birth intervals (24 through 35, 36 through 47, and 48 through 71 months). Effects were particularly marked for birth weight, postneonatal mortality, and anthropometric status at mean age 19 months. Children born after a long birth interval (&gt;71 months) also showed some disadvantage for birth weight, perinatal mortality, and infant mortality. However, this group experienced lower risks of hospitalizations during the first 19 months of life and better anthropometric status at mean age 19 months. This study provides data that are scarce from such settings and contributes to the quantification of associations between birth spacing and child health. This information is important in the planning of appropriate intervention strategies.

AbstractPrematurity, size at birth, and postnatal growth are important factors that determine cardiometabolic and neurodevelopmental outcomes later in life. In the present study, we aimed to investigate the associations between the size at birth and growth velocity after birth with cardiometabolic and neurodevelopmental outcomes in preterm infants. Fifty-six preterm infants born at < 32 weeks of gestation or having a birth weight of < 1500 g were enrolled and categorized into small for gestational age (SGA) and appropriate for gestational age (AGA) groups. Anthropometric and cardiometabolic parameters were assessed at school-age, and the Korean Wechsler Intelligence Scale for Children, fourth edition (K-WISC-IV) was used for assessing the intellectual abilities. The growth velocity was calculated by changes in the weight z-score at each time period. Multivariate analysis was conducted to investigate the associations of growth velocity at different periods with cardiometabolic and neurodevelopmental outcomes. Forty-two (75%) were classified as AGA and 25% as SGA. At school-age, despite the SGA children showing significantly lower body weight, lean mass index, and body mass index, there were no differences in the cardiometabolic parameters between SGA and AGA groups. After adjusting for gestational age, birth weight z-score, weight z-score change from birth to discharge and sex, change in weight z-score beyond 12 months were associated with a higher systolic blood pressure, waist circumference, and insulin resistance. Full-scale intelligent quotient (β = 0.314, p = 0.036) and perceptional reasoning index (β = 0.456, p = 0.003) of K-WISC-IV were positively correlated with postnatal weight gain in the neonatal intensive care unit. Although cardiometabolic outcomes were comparable in preterm SGA and AGA infants, the growth velocity at different time periods resulted in different cardiometabolic and neurocognitive outcomes. Thus, ensuring an optimal growth velocity at early neonatal period could promote good neurocognitive outcomes, while adequate growth after 1 year could prevent adverse cardiometabolic outcomes in preterm infants.

For the last few decades, demographers have directed considerable attention towards the study of human fertility through the analysis of birth interval data. This study examines the covariates of birth intervals and the effect of increased birth intervals on current fertility level in Bangladesh. Using the data of BDHS 2007, Cox Proportional Hazards model is used to determine the covariates of birth intervals. Mother’s age at first birth, previous birth interval, mother’s education and working status, mass media exposure appeared as the significant determinants of birth intervals. To estimate the tempo effect of birth interval on current fertility of Bangladesh, Bongaarts and Feeney method (1998) has been used. The tempo adjusted TFR was found to be 3.85, while the conventional TFR was 2.73 for the year 2005-06. This demonstrates that an increased effort to widen the spacing of births can effectively reduce the level of fertility in the future. Dhaka Univ. J.

BackgroundParenteral nutrition associated cholestasis (PNAC) is a frequently observed pathology in extremely low birth weight (ELBW) infants. Its pathogenesis is determined by the composition and duration of parenteral nutrition (PN) as well as the tolerance of enteral feeds (EF). “Aggressive” nutrition is increasingly used in ELBW infants to improve postnatal growth. Little is known about the effect of “aggressive” nutrition on the incidence of PNAC. We analyzed the influence of implementing an “aggressive” nutritional regimen on the incidence of PNAC and growth in a cohort of ELBW infants.MethodsELBW infants were nourished using a “conservative” (2005–6;n= 77) or “aggressive” (2007–9;n= 85) nutritional regimen that differed in the composition of PN after birth as well as the composition and timing of advancement of EFs. We analyzed the incidence of PNAC (conjugated bilirubin > 1.5 mg/dl (25 µmol/l)) corrected for confounders of cholestasis (i.e., NEC and/or gastrointestinal surgery, sepsis, birth weight, Z-score of birth weight, time on PN and male sex), growth until discharge (as the most important secondary outcome) and neonatal morbidities.ResultsThe incidence of PNAC was significantly lower during the period of “aggressive” vs. “conservative “nutrition (27% vs. 46%,P< 0.05; adjusted OR 0.275 [0.116–0.651],P< 0.01). Body weight (+411g), head circumference (+1 cm) and length (+1 cm) at discharge were significantly higher. Extra-uterine growth failure (defined as a Z-score difference from birth to discharge lower than −1) was significantly reduced for body weight (85% vs. 35%), head circumference (77% vs. 45%) and length (85% vs. 65%) (P< 0.05). The body mass index (BMI) at discharge was significantly higher (11.1 vs. 12.4) using “aggressive” nutrition and growth became more proportionate with significantly less infants being discharged below the 10th BMI percentile (44% vs. 9%), while the percentage of infants discharged over the 90th BMI percentile (3% vs. 5%) did not significantly increase.Discussion“Aggressive” nutrition of ELBW infants was associated with a significant decrease of PNAC and marked improvement of postnatal growth.

Background The association between birth outcomes and child maltreatment remains controversial. The purpose of this study is to test whether infants without congenital or chronic disease who are low birth weight (LBW), preterm, or small for gestational age (SGA) are at an increased risk of being maltreated. Methods A hospital-based case-control study of infants without congenital or chronic diseases who visited the National Center for Child Health and Development, Tokyo, between April 1, 2002 and March 31, 2005 was conducted. Cases (N = 35) and controls (N = 29) were compared on mean birth weight, gestational age, and z-score of birth weight. Results SGA was significantly associated with infant maltreatment after adjusting for other risk factors (adjusted odds ratio: 4.45, 95% CI: 1.29–15.3). LBW and preterm births were not associated with infant maltreatment. Conclusion Infants born as SGA are 4.5 times more at risk of maltreatment, even if they do not have a congenital or chronic disease. This may be because SGA infants tend to have poorer neurological development which leads them to be hard-to-soothe and places them at risk for maltreatment.

SummaryTo examine the effects of birth spacing on early childhood mortality, 3729 singleton births in 1983–84 were followed for 3 years in rural Bangladesh. Logistic regression analyses were used to assess whether the survival of older siblings modifies the effect of preceding birth intervals and to see if the effects of preceding and succeeding birth intervals are inter-related, controlling for the effects of sex of the child, mother's age and household economic status. With the exception of the neonatal period, birth spacing effects were highly significant. A preceding birth interval of <15 months was associated with a greater mortality risk in the post-neonatal period for children with an older sibling who survived infancy. However, a short preceding birth interval did not adversely affect post-neonatal mortality if the older sibling died in infancy. Neonatal and post-neonatal deaths were higher if older siblings had died in respective age intervals. A pregnancy interval of <12 months after childbirth raised the risk of death at ages 1–2 years considerably if the child was born after a short birth interval (<15 months). The results suggest that the high mortality risks of closely spaced children are due to sibling competition for parental resources.

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 summarize 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 98 studies retrieved, 15 articles were included in the final review. All included articles represent low- and middle-income countries. 80% 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.

Background: Perinatal mortality includes both deaths in the first week of life and fetal deaths (stillbirths). Over 130 million babies are born every year, and more than 10 million infants die before their fifth birthday and almost 8 million before their first birthday.Objectives: To make an effort to find out impact of birth interval on fetal outcomes like, low birth weight (weight less than 2500 grams regardless of gestational age), perinatal death (death within 28 weeks of gestation to 7 days of birth) in subsequent pregnancies.Methods: This was a cross-sectional study conducted in BPKIHS, Dharan in 2011. Patients included were women of second gravida between age group 20 -35 years .The consecutive convenience sampling method was used to collect the data. Study population was divided into three birth interval groups of <18, 18-59,>59 months respectively and fetal outcomes (low birth weight, gestational age, early neonatal death, Apgar score) were compared.Results: Out of included population majority (55.63%) of the women had age range of 20-25 years with the mean age of 25.30. Among the total 168 who were included 20(11.91%) were belongs to birth interval <18 months, 113(67.26%) were found in 18-59 months group and 35(20.83%) were in >59 months group.Conclusion: There was increased risk of preterm and low birth weight and perinatal death in women with birth interval <18 months as compared to women with birth interval 18-59 months and groups >59 months. Health Renaissance 2015;13(3): 169-176

Abstract Background Newborn screening (NBS) for cystic fibrosis (CF) improves nutritional outcomes. Despite early dietetic intervention some children fail to grow optimally. We report growth from birth to 2 years in a cohort of children diagnosed with CF by NBS and identify the variables that influence future growth. Methods One hundred forty-four children were diagnosed with CF by the West Midlands Regional NBS laboratory between November 2007 and October 2014. All anthropometric measurements and microbiology results from the first 2 years were collated as was demographic and CF screening data. Classification modelling was used to identify the key variables in determining future growth. Results Complete data were available on 129 children. 113 (88%) were pancreatic insufficient (PI) and 16 (12%) pancreatic sufficient (PS). Mean birth weight (z score) was 3.17 kg (− 0.32). There was no significant difference in birth weight (z score) between PI and PS babies: 3.15 kg (− 0.36) vs 3.28 kg (− 0.05); p = 0.33. By the first clinic visit the difference was significant: 3.42 kg (− 1.39) vs 4.60 kg (− 0.48); p < 0.0001. Weight and height remained lower in PI infants in the first year of life. In the first 2 years of life, 18 (14%) infants failed to regain their birth weight z score. The median time to achieve a weight z score of − 2, − 1 and 0 was 18, 33 and 65 weeks respectively. The median times to reach the same z scores for height were 30, 51 and 90 weeks. Birth weight z score, change in weight z score from birth to first clinic, faecal elastase, isolation of Pseudomonas aeruginosa, isolation of Staphylococcus aureus and sweat chloride were the variables identified by the classification models to predict weight and height in the first and second year of life. Conclusions Babies with CF have a lower birth weight than the healthy population. For those diagnosed with CF by NBS, the weight difference between PI and PS babies was not significantly different at birth but became so by the first clinic visit. The presence of certain factors, most already identifiable at the first clinic visit can be used to identify infant at increased risk of poor growth.
