Parenting experiences of mothers of moderate-to-late preterm children in South Korea: a qualitative study

Impact of the child's birth weight on maternal misperceptions of young children's weight: A retrospective study with nationally representative data

AIM

A young child's abnormal birth weight (BW) can affect a mother's misperceptions of her child's weight, potentially hindering the child's health management. Therefore, this study investigated the impact of children's BW on maternal misperceptions of children's weight during early childhood.

METHODS

A retrospective study was conducted for 485,095 children who were 54-60 months of age, born between 2011 and 2013, and participated in South Korea's Sixth National Health Screening Program for Infants and Children (NHSPIC). Data on BW, weight, sex, birth year, preterm birth, breastfeeding history, maternal age, mothers' perceptions of the child's weight, and socioeconomic status were collected and incorporated in the final analysis via data linkage between the NHSPIC and Korean healthcare claims information. Multiple logistic regression analysis was applied to identity the impact of BW on mothers' misperceptions of children's weight, after adjustment for all variables.

RESULTS

Low BW (LBW) children had the lowest proportion (57.1%) of mothers who accurately identified their child's weight compared to normal or high BW. LBW was an independent factor affected maternal misperception of the child's weight (underestimation: adjusted odds ratio [aOR]: 1.46, 95% confidence interval [CI]: 1.41-1.52; overestimation: aOR: 0.84, 95% CI: 0.73-0.97). Overweight or underweight status, male gender, preterm birth, a younger mother, and low socioeconomic status were also associated with both underestimation and overestimation.

CONCLUSION

LBW emerged as an important risk factor for maternal misperception of a child's weight. Therefore, pediatric nurses need to apply interventions to improve perceptions of children's weight among mothers of young LBW children.

Impact of moderate-to-late preterm birth on neurodevelopmental outcomes in young children: Results from retrospective longitudinal follow-up with nationally representative data

This study investigated the relationship between moderate-to-late preterm (MLPT) birth and the risk of neurodevelopmental impairments (NIs) in young children compared with the risks associated with very preterm (VPT) and full-term (FT) birth based on nationally representative large-scale population data. Retrospective follow-up was conducted over 71 months for 738,733 children who were born and participated in the Korean National Health Screening Program for Infants and Children (NHSPIC) between 2011 and 2013. Using a data linkage between the NHSPIC and Korean healthcare claim information, data on birth year, sex, delivery type, birth weight, growth abnormality, gestational age, breastfeeding history, maternal age, NIs, multiple gestation, preterm labor, premature rupture of membranes (PROM), gestational diabetes, gestational hypertension, smoking during pregnancy, and socioeconomic status were collected and included in the final analysis. Cox proportional hazards models were applied to identify the impact of gestational age on NI risk, with all variables adjusted as appropriate. Overall, 0.9% and 3.8% rates of VPT and MLPT births were identified, respectively. NI incidence was highest among VPT children (34.7%), followed by MLPT (23.9%) and FT (18.2%) children. Both VPT (hazard ratio [HR], 1.45; 95% confidence interval [CI], 1.03 to 2.05) and MLPT (HR, 1.21; 95% CI, 1.04 to 1.41) births were associated with increased NI risk. Low birth weight, PROM, and smoking during pregnancy were also associated with increased NI risk, while longer breastfeeding and higher socioeconomic status were associated with decreased risk. Special attention must be given to NIs for both VPT and MLPT children.
