Purpose
This study examined the effects of upright nesting compared with swaddling on physiological status, sleep duration, and feeding tolerance in preterm infants in the neonatal intensive care unit.
Methods
A total of 48 preterm infants, 24 per group, with gestational ages of 31 to 36 weeks, were enrolled. During the study, all infants were fed every 2 hours and did not receive sedation. Those requiring respiratory support or presenting with congenital abnormalities were excluded. At the unit level, participants were assigned to the “upright nesting” or the “swaddling” group. Physiological parameters, such as body temperature, oxygen saturation, heart rate, and respiratory rate, as well as sleep duration and feeding tolerance, were measured over 3 consecutive days. To examine group effects, time effects, and group-by-time interactions, linear mixed models were applied.
Results
Baseline characteristics, including sex, birth weight, and gestational age, were comparable between groups. Infants receiving upright nesting showed higher mean body temperature and oxygen saturation, lower heart rate, longer sleep duration, and improved feeding tolerance. Linear mixed models presented significant main effects of time for temperature, oxygen saturation, and heart rate, while significant group effects were presented for sleep duration and feeding tolerance. Group by time interactions were not statistically significant, suggesting favorable trends without differential change over time.
Conclusion
Upright nesting supports physiological stability, promotes longer sleep duration, and enhances feeding tolerance in preterm infants. Furthermore, it is a promising supportive strategy in neonatal intensive care, but larger studies are needed to confirm the results.

Purpose
This study explored the intrapersonal, interpersonal, and school factors, following the socioecological model, associated with sugar-sweetened beverage (SSB) consumption in Korean high-school students.
Methods
A total of 231 students from first to third grade, aged 15–18 years, participated in this cross-sectional study. Multiple linear regression analysis was conducted to identify the factors.
Results
Among the intrapersonal factors, fast-food consumption (β=0.13, t=1.97, p=.050) and habit strength of SSB consumption were positively associated (β=0.35, t=4.30, p<.001), and sleep duration was negatively associated with SSB consumption (β=–0.14, t=–2.02, p=.045). Among interpersonal factors, perceived SSB consumption by peers was positively associated (β=0.30, t=4.93, p<.001), and among school factors, vending machines at school (β=0.13, t=2.07, p=.039) and supermarkets and convenience stores near schools were positively associated with SSB consumption (β=0.17, t=2.87, p=.005).
Conclusion
School nurses should propose policies and interventions that consider the multilevel factors to reduce SSB consumption in adolescents.

Purpose
This study aimed to identify factors-both infant-related and maternal-associated with pressure to eat as a feeding practice among mothers with infants.
Methods
This study used a cross-sectional design and included 163 mothers of infants aged 2~12 months. Of the 180 self-reported questionnaires that were distributed, 163 (91%) were included in the data analysis. Multiple regression analysis was used to identify the factors associated with pressure to eat as a feeding practice among the mothers.
Results
Infant’s temperament (β=-.17, p=.035), mother’s body mass index (β=-.16, p=.048), and concern about the infant being underweight (β=.30, p=.001) were associated with pressure to eat as a feeding practice among mothers. The explanatory power of these variables in the predictive model was 19.2%.
Conclusion
Educational programs should be developed for improving mother’s awareness of cues from infants with difficult temperament. In addition, educational interventions regarding the correct evaluation of infant’s weight are needed to relieve mother’s concern about their infant’s being underweight. These interventions might be helpful to reduce the prevalence of pressure to eat as a feeding practice among mothers with infants.
