Analyzing effects on anterior open bite in twins by PLS-SEM and sobel test.

OBJECTIVE: This study aimed to assess the different pathways between predictor factors such as zygosity, atypical swallowing, mouth breathing, breastfeeding and bottle feeding related to anterior open bite (AOB) in twins. METHODS: The study was conducted in monozygotic (MZ) and dizygotic (DZ) twin children aged 3-15 years. AOB, atypical swallowing, mouth breathing, feeding type, duration of bottle use, and mouth opening status during sleep were recorded during oral examination. Partial least squares structural equation model (PLS-SEM) and sobel tests were performed to assess the total and indirect effects among the variables on AOB. RESULTS: A total of 404 children (29.2% MZ;70.8% DZ) participated in this study. The effect of zygosity on mouth breathing in the PLS-SEM model was statistically significant. Conversely, it was determined that mouth breathing effected that atypical swallowing (p = 0.001). Atypical swallowing triggered AOB (p = 0.001). The atypical swallowing has a mediation effect between AOB and mouth breathing (p = 0.020). Mouth breathing causes atypical swallowing and therefore indirectly increases the likelihood of AOB. While breastfeeding decreases AOB incidence (p = 0.023), bottle feeding increases AOB incidence (p = 0.046). The sobel tests show that the fully mediator variable feature of mouth breathing is statistically significant in the negative relation between zygosity and atypical swallowing. CONCLUSION: The PLS-SEM model showed that mouth breathing triggers atypical swallowing and atypical swallowing triggers AOB. As a result of this chain of relationships, an indirect effect of zygosity on AOB was observed. According to sobel tests, zygosity has an indirect effect on atypical swallowing through mouth breathing, while mouth breathing has a positive indirect effect on AOB through atypical swallowing. CLINICAL RELEVANCE: This study identified the relationships between different factors and the presence of AOB. The findings of this study demonstrate in detail the relationships between AOB and zygosity, atypical swallowing, mouth breathing, breastfeeding and bottle feeding. Brestfeeding has a reducing effect on the frequency of AOB. Among the nutritional forms, breastfeeding ensures the proper development of the stomatognathic system by working the oro-facial muscles.

Longitudinal assessment of sleep and fatigue according to baby feeding method in postpartum women: a prospective observational study.

BACKGROUND: Poor subjective sleep quality, depressive symptoms and fatigue occur frequently in postpartum. However, the dynamics of their respective associations from prepartum throughout the maternity period in function of baby feeding method have not been fully elucidated. METHODS: Prospective, longitudinal study using validated questionnaires probing for sleep quality, insomnia, fatigue and depressive symptoms at 35-37 weeks of gestation and at 2, 8 and 12 weeks postpartum in the obstetric departments of two Flemish hospitals. Somers'd ordinal correlation was used for correlations between the results of questionnaires (ratio variables) and the feeding method variable (an ordinal variable); T tests (normal data) or Mann Whitney (non normal data) tests for equality of means; ordinal regression ('Proportional odds model') to investigate the predictive value of parameters at one moment on the feeding method choice at a later moment; logistic regression to investigate the predictive value of parameters on later change of feeding method. RESULTS: 188 women indicating a choice for either bottle or breastfeeding in prepartum (27-35 weeks' gestation) were included. Higher fatigue assessed through the Fatigue Severity Scale within late pregnancy was moderately associated with primary bottle feeding choice. Fatigue decreased at early and late postpartum in bottle feeding (-0.38 ± 1.04; p = .110 and - 0.31 ± 1.01; p = .642 respectively), but remained unchanged from late pregnancy through early and late postpartum in breastfeeding (0.04 ± 1.21; p = .110 and - 0.27 ± 0.96; p = .642 respectively), resulting in similar fatigue in both feeding methods in early through late postpartum. There were no differences in sleep quality or insomnia symptoms at all time points. Presence of postpartum depressive symptoms were associated with early switching to bottle feeding (Somers' d correlation 0.11 (p = .021). CONCLUSIONS: Fatigue and depressive symptoms are inversely associated with breastfeeding initiation or maintenance and influence feeding method dynamics.

Effects of feeding patterns during the first 6 months on weight development of infants ages 0-12 months: a longitudinal study.

The purpose of this study was to investigate the effect of feeding patterns during the first 6 months on weight development of infants ages 0-12 months. Using monitoring data from the Maternal and Child Health Project conducted by the National Center for Women and Children's Health of the Chinese Center for Disease Control and Prevention from September 2015 to June 2019, we categorized feeding patterns during the first 6 months as exclusive breastfeeding, formula feeding, or mixed feeding. We calculated weight-for-age Z scores (WAZ) according to the World Health Organization's (WHO) 2006 Child Growth Standard using WHO Anthro version 3.2.2. A multilevel model was used to analyze the effect of feeding patterns during the first 6 months on the WAZ of infants ages 0-12 months in monitoring regions. Length of follow-up (age of infants) was assigned to level 1, and infants was assigned to level 2. Characteristics of infants, mothers, and families and region of the country were adjusted for in the model. The average weight of infants ages 0-12 months in our study (except the birth weights of boys who were formula fed or mixed fed) was greater than the WHO growth standard. After we adjusted for confounding factors, the multilevel model showed that the WAZ of exclusively breastfed and mixed-fed infants were statistically significantly higher than those of formula-fed infants (coefficients = 0.329 and 0.159, respectively; P < 0.05), and there was a negative interaction between feeding patterns and age (both coefficients = - 0.020; P < 0.05). Infants who were exclusively breastfed were heavier than formula-fed infants from birth until 12 months of age. Mixed-fed infants were heavier than formula-fed infants before 8 months, after which the latter overtook the former. Infants' weight development may be influenced by feeding patterns during the first 6 months. Exclusive breastfeeding during the first 6 months may be beneficial for weight development of infants in infancy.

The transition from tube feeding to oral feeding algorithm in preterm infants: case-control study.

BACKGROUND: Oral feeding is a complex sensorimotor process influenced by many variables, making it challenging for healthcare providers to introduce and manage it. Feeding practice guided by tradition or a trial-and-error approach may be inconsistent and potentially delay the progression of oral feeding skills. AIM: To apply a new feeding approach that assesses early oral feeding independence skills of preterm infants in the neonatal intensive care unit (NICU). To prove its effectiveness, compare two approaches of oral feeding progression based on clinical outcomes in preterm infants, the traditional approach used in the NICU of Mansoura University Children Hospital (MUCH) versus the newly applied approach. METHODS: A quasi-experimental, exploratory, and analytical design was employed using two groups, control and intervention groups, with 40 infants for the first group and 41 infants for the second one. The first group (the control) was done first and included observation of the standard practice in the NICU of MUCH for preterm oral feeding, in which oral feeding was dependent on post-menstrual age (PMA) and weight for four months. The second group (the intervention) included early progression to oral feeding depending on early assessment of Oral Feeding Skills (OFS) and early supportive intervention and/or feeding therapy if needed using the newly developed scoring system, the Mansoura Early Feeding Skills Assessment "MEFSA" for the other four months. Infants in both groups were studied from the day of admission till discharge. RESULTS: In addition to age and weight criteria, other indicators for oral feeding readiness and oral motor skills were respected, such as oral feeding readiness cues, feeding practice, feeding maintenance, and feeding techniques. By following this approach, preterm infants achieved earlier start oral feeding (SOF) and full oral feeding (FOF) and were discharged with shorter periods of tube feeding. Infants gained weight without increasing their workload to the NICU team. CONCLUSION: The newly applied approach proved to be a successful bedside scoring system scale for assessing preterm infants' early oral feeding independence skills in the NICU. It offers an early individualized experience of oral feeding without clinical complications.

Feeding modalities, HIV transmission and its predictors among HIV-exposed infants visited Gamo and Gofa zones public health facilities, Southern Ethiopia: a retrospective follow up study.

BACKGROUND: Despite the highest (88%) Prevention of Mother-To-Child Transmission (PMTCT) of HIV coverage in Eastern Africa, 50% of new HIV infections in children aged 0-14 years occur in the region. OBJECTIVE: The aim of this study was to assess the feeding modalities, the rate of HIV transmission and its predictors among HIV exposed infants (HIV-EIs) visited Gamo and Gofa Zones public health facilities, Southern Ethiopia from January 2013 to February 2019. METHOD AND MATERIALS: Institution-based retrospective follow up study was employed among 450 HIV-EIs having DNA/PCR test results. All infant-mother pair records in selected health facilities were reviewed using a standard data extraction tool from March to July 2019. HIV transmission probabilities were assessed by Kaplan-Meier time-to-event analysis method and log-rank tests were used to compare the risk among different groups. The Cox-proportional hazards model, adjusted on infant feeding modalities and other co-variants was used to identify predictors of HIV transmission, and statistical significance was declared at a p-value of < 0.05. RESULTS: In total, 383 complete records were analyzed. In the study, 85.6% (95%CI: 81.6%, 89.1%) of HIV-EIs were exclusively breastfed in the first six months. The 18 months probability of infant HIV transmission was 64 (16.7%) (95%CI: 13.1%-20.8%). The risk of HIV-transmission was higher among infants who were delivered at the hospital than health centers/health posts (AHR = 3.07; 95%CI: 1.19, 7.95); discontinued Cotrimoxazole prophylaxis in at least one visit (AHR = 6.32; 95%CI: 3.35, 11.94); did not exclusively breastfeed (AHR = 3.07; 95%CI: 1.72, 5.47) and came from urban areas (AHR = 5.90; 95%CI: 1.40, 24.85). CONCLUSIONS: The study showed that HIV-EIs had a greater rate of 18 months HIV transmission than the national pooled prevalence. The risk of transmission is higher among infants who do not breastfeed exclusively for the first 6 months, and the risk increases with the number of months spent by breastfeeding. Therefore, strengthening counselling on safer feeding options and Cotrimoxazole prophylaxis use; provision of quality PMTCT service with special focus in hospitals and urban residents were recommended.

Bottle-feeding practice and its associated factors among mothers of children aged 0 to 23 months in sub-Saharan Africa: a multi-level analysis of demographic and health surveys (2015-2022).

BACKGROUND: Avoidance of bottle feeding is recommended as it interferes with optimal suckling behavior, is difficult to keep clean, and is an important route for the transmission of pathogens. However, there is a current shift towards breastfeeding for a short period and the introduction of bottle feeding in both the developed and developing worlds. Bottle-feeding practice and its individual- and community-level determinants are not addressed in sub-Saharan Africa. Therefore, this study aimed to fill this gap and assess the pooled prevalence and associated factors of bottle feeding among mothers of children less than 23 months of age. METHODS: Data from the recent demographic and health surveys of 20 countries in sub-Saharan Africa conducted between 2015 and 2022 were used. A total weighted sample of 86,619 mother-child pairs was included in the current study. Multilevel mixed-effects logistic regression was used to determine the factors associated with the outcome variable. Intra-class correlation coefficient, likelihood ratio test, median odds ratio, and deviance (-2LLR) values were used for model comparison and fitness. Finally, variables with a p-value < 0.05 and an adjusted odds ratio with a 95% confidence interval were declared statistically significant. RESULTS: The overall pooled prevalence of bottle feeding among mothers of children aged 0 to 23 months in sub-Saharan Africa was 13.74% (95% CI: 13.51%, 13.97%). Factors like maternal age [AOR = 1.09; 95% CI (1.04, 1.14)], educational status [AOR = 2.83; 95% CI (2.58, 3.10)], marital status [AOR = 1.16; 95% CI (1.09, 1.24)], maternal occupation [AOR = 0.76; 95% CI (0.73, 0.79)], media exposure [AOR = 0.80; 95% CI (0.76, 0.85)], wealth index [AOR = 1.21; 95% CI (1.15, 1.29)], sex of the household head [AOR = 1.17; 95% CI (1.12, 1.24)], family size [AOR = 1.06; 95% CI (1.01, 1.12)], number of under-five children [AOR = 1.11; 95% CI (1.04, 1.19)], place of delivery [AOR = 1.06; 95% CI (1.00, 1.12)], mode of delivery [AOR = 1.41; 95% CI (1.31, 1.52)], counseling on breastfeeding [AOR = 0.88; 95% CI (0.84, 0.92)], age of the child [AOR = 1.65; 95% CI (1.57, 1.75)], and residence [AOR = 1.64; 95% CI (1.56, 1.72)] were significantly associated with bottle-feeding practices. CONCLUSION: Nearly one out of seven children aged 0 to 23 months received bottle feeding in sub-Saharan African countries. Older mothers, higher mothers' educational status, unmarried women, richest families, non-working mothers, exposed to media, female-headed households, large family size, having one under-five children, home delivery, cesarean delivery, children aged 6-11 months, and urban residence were significantly associated with an increased risk of bottle feeding. Breastfeeding promotion programs are advised to target mothers who are older, educated, working, rich, gave birth at home, have a large family size, are delivered by cesarean section, have children aged 6-11 months, and reside in urban areas to achieve a significant decrease in bottle feeding rates in sub-Saharan Africa.

A simple step to improve fat and energy delivery of human milk delivered via bottle-feeding pump: An experimental study.

BACKGROUND: Enteral feeding pump systems deliver decreased amounts of macronutrients in human milk to neonates. This study determined the macronutrient loss associated with a bottle-feeding pump system and the effect of manually mixing the human milk during extended feeds. METHODS: Macronutrient content from samples of donor human milk was analyzed after simulated extended feeds with a bottle-feeding pump system, using a human milk analyzer. Simulations were repeated using manual mixing of the bottle every 30 min during feeding. The percentage of the baseline was calculated, and one-sample t tests and analysis of variance compared the effect of manual mixing and the duration of feeding on macronutrient delivery. RESULTS: The delivery of fat and energy was lower over time, but manual mixing considerably improved retention. The length of feeding impacted fat delivery, with less fat delivered over time (P < 0.001). Manually mixing significantly increased fat delivery (P < 0.001). Similar results were found for energy, with a significant reduction in energy delivery over time (P < 0.001) and significantly more energy delivered with mixing (P < 0.001). Mixing and the duration of feeding had minimal effect on protein or carbohydrate delivery. CONCLUSIONS: Bottle-feeding pump systems are associated with a significant reduction in the delivery of fat and energy of donor human milk. The manual mixing of donor human milk during prolonged feeds is a simple way to improve fat and energy delivery to the neonate.

The effect of position on feeding performance in infants with cleft lip and palate: Quasiexperimental study.

PURPOSE: This single-group, quasiexperimental study was conducted to determine the effect of feeding position on the physiological parameters and feeding performance of term-born infants with cleft lip and palate (CLP) in the preoperative period. METHODS: The study sample consisted of 45 infants aged 0-6 months with CLP followed up preoperatively in our outpatient clinic between January 2021 and 2022. Infants who were being fed with a specialty bottle for babies with CLP and whose families consented to participate in the study were included. After 2 h of fasting, the infants were fed in the elevated supine (ESU) position for the first meal, then in the elevated side-lying (ESL) position for the second meal after another 2 h of fasting. The infants' heart rate and oxygen saturation values before, during, and after each feed and indicators of feeding performance were compared between the positions. RESULTS: There was no significant difference between the positions in terms of heart rate and oxygen saturation before, during, or after feeding (p > .05). There was no statistically significant difference in measures of feeding performance according to the infants' feeding position (p > .05). CONCLUSION: According to the findings obtained in this study, infants with CLP showed no statistically significant differences in heart rate, oxygen saturation, or feeding performance when fed in the ESL and ESU positions. PRACTICE IMPLICATIONS: However, despite the lack of statistical significance, both physiological values and feeding performance tended to be better when the infants were fed in the ESL position, nurses can practice ESL position according to the infant's opposite direction of the side of the cleft lip or palate.

The role of breastfeeding and formula feeding regarding depressive symptoms and an impaired mother child bonding.

Associations between depressive symptoms and breastfeeding are well documented. However, evidence is lacking for subdivisions of feeding styles, namely exclusive breastfeeding, exclusive formula feeding and a mixed feeding style (breastfeeding and formula feeding). In addition, studies examining associations between mother-child-bonding and breastfeeding have yielded mixed results. The aim of this study is to provide a more profound understanding of the different feeding styles and their associations with maternal mental health and mother-child-bonding. Data from 307 women were collected longitudinally in person (prenatally) and by telephone (3 months postnatally) using validated self-report measures, and analyzed using correlational analyses, unpaired group comparisons and regression analyses. Our results from a multinomial regression analysis revealed that impaired mother-child-bonding was positively associated with mixed feeding style (p = .003) and depressive symptoms prenatal were positively associated with exclusive formula feeding (p = .013). Further studies could investigate whether information about the underlying reasons we found for mixed feeding, such as insufficient weight gain of the child or the feeling that the child is unsatiated, could help prevent impaired mother-child-bonding. Overall, the results of this study have promising new implications for research and practice, regarding at-risk populations and implications for preventive measures regarding postpartum depression and an impaired mother-child-bonding.

Exploration of the Association Between Sucking Measures and Ability to Attain Independent Oral Feeds Among Infants Who Are Born Preterm.

IMPORTANCE: Infants who are born preterm often experience difficulty transitioning from full tube to independent oral feeds, which often prolongs their hospital stay. No clinical measures associated with attainment of independent oral feeds are currently available. OBJECTIVE: To identify specific nutritive sucking measures associated with time to attainment of independent oral feeds among infants who are born preterm. DESIGN: An observational cohort pilot study was undertaken. SETTING: A Level 2 to Level 3 neonatal intensive care unit. PARTICIPANTS: Fourteen infants (7 male, 7 female) born at or less than 34 wk gestation were enrolled. OUTCOMES AND MEASURES: The monitored suck measures included average suck strength (millimeters of mercury), average sucking burst duration (seconds), average suck count (number of sucks), and average pause duration (seconds). Time to independent oral feeds (days) and baseline characteristics were also monitored. The nutritive sucking measures were recorded once, during the first 5 min of an oral feed, when infants were taking an average of three to four oral feeds per day using a nipple monitoring device. RESULTS: An inverse relation was found among average suck burst duration (p = .04), gestational age (p = .03), and days to attainment of independent oral feeds. CONCLUSIONS AND RELEVANCE: Study results suggest that average sucking burst duration, during the first 5 min of an oral feed, is associated with time to attain independent oral feeds. Plain-Language Summary: Sucking burst duration is a simple measure that may be used clinically to identify early on infants who may have trouble transitioning from full tube to independent oral feedings. The results of this study suggest that a suck burst duration in the first 5 min of an oral feeding is inversely associated with the length of time to achieve independent oral feeding. The results highlight the importance of considering an infant's nutritive sucking ability when evaluating their potential to achieve independent oral feedings.

The effects of simulated gastroesophageal reflux on infant pig oropharyngeal feeding physiology.

The neural connectivity among the oral cavity, pharynx, and esophagus is a critical component of infant feeding physiology. Central integration of oral and pharyngeal afferents alters motor outputs to structures that power swallowing, but the potential effects of esophageal afferents on preesophageal feeding physiology are unclear. These effects may explain the prevalence of oropharyngeal dysphagia in infants suffering from gastroesophageal reflux (GER), though the mechanism underlying this relationship remains unknown. Here we use the validated infant pig model to assess the impacts of simulated GER on preesophageal feeding parameters. We used high-speed videofluoroscopy and electromyography to record bottle-feeding before and following the infusion of a capsaicin-containing solution into the lower esophagus. Sucking parameters were minimally affected by capsaicin exposure, such that genioglossus activity was unchanged and tongue kinematics were largely unaffected. Aspects of the pharyngeal swallow were altered with simulated GER, including increased thyrohyoid muscle activity, increased excursions of the hyoid and thyroid per swallow, decreased swallow frequency, and increased bolus sizes. These results suggest that esophageal afferents can elicit changes in pharyngeal swallowing. In addition, decreased swallowing frequency may be the mechanism by which esophageal pathologies induce oropharyngeal dysphagia. Although recent work indicates that oral or pharyngeal capsaicin may improve dysphagia symptoms, the decreased performance following esophageal capsaicin exposure highlights the importance of designing sensory interventions based upon neurophysiology and the mechanisms underlying disordered feeding. This mechanistic approach requires comprehensive data collection across the entirety of the feeding process, which can be achieved using models such as the infant pig.NEW & NOTEWORTHY Simulated gastroesophageal reflux (GER) in an infant pig model resulted in significant changes in pharyngeal swallowing, which suggests that esophageal afferents are centrally integrated to alter motor outputs to the pharynx. In addition, decreased swallow frequency and increased bolus sizes may be underlying mechanisms by which esophageal pathologies induce oropharyngeal dysphagia. The infant pig model used here allows for a mechanistic approach, which can facilitate the design of intervention strategies based on neurophysiology.

Breastfeeding Practice Before Bottle-Feeding: An Initiative to Increase the Rate of Breastfeeding for Preterm Infants at the Time of Neonatal Intensive Care Unit Discharge.

Preterm babies who received 72 hours of breastfeeding practice before introducing a bottle had significantly higher rates of breastfeeding at the time of neonatal intensive care unit (NICU) discharge than did babies who were introduced to bottle-feeding with or before breastfeeding during the first 72 hours of oral feeding or babies who were primarily bottle-fed. There were no statistical differences in corrected gestational age (CGA) at birth, first oral feeding, or full oral feeds, in days from first to full oral feeds, or in CGA or days of life at NICU discharge.

Biomonitoring Study of Urinary Bisphenol A Levels and Impact of Bottle-Feeding Practices Among Infants and Children From Northern India.

OBJECTIVES: To compare the urinary bisphenol A (BPA) levels in bottle-fed and never bottle-fed infants and under-five children and to determine the impact of bottle-feeding practices and sociodemographic factors on urinary BPA levels. METHODS: A community-based cross-sectional study was carried out on children aged between 2 to 60 months attending the Anganwadi centres in Chandigarh. RESULTS: Urine samples were collected from 184 children, out of which 94.56% (n = 174) children had detectable urinary BPA levels. The mean (SD) BPA level was 2.74 (2.60) ng/ml and BPA was detected in 93.9% of 'ever' bottle-fed children (n = 93/99) and 95.3% of 'never' bottle-fed children (n = 81/85) (P = 0.69). On multivariate regression analysis, there were no significant predictors for high (≥ 75th percentile) urinary BPA levels. Still, the odds of urinary BPA levels ≥75th percentile showed higher trend for significance among children from middle/higher socioeconomic background in reference to lower socioeconomic stratum (adjusted OR 7.02; 95% CI 1.24, 133.25; P = 0.07) and among children whose feeding bottles were brushed once or twice daily in reference to group with no daily brushing (adjusted OR 3.92, 95% CI 0.95, 20.56; P = 0.07). CONCLUSIONS: Although feeding with plastic bottle did not emerge as a statistically significant risk factor for BPA exposure, yet detection of BPA levels among majority of study children signals urgent need for unmasking exposure to other sources given the potential long-term toxicity of BPA among infants and young children.

Infant Oral Candidiasis and Bottle Cleaning Methods: A Descriptive Study.

As manufacturers produce bottles with additional parts, such as an anticolic straw, cleaning time increases. Increased cleaning time potentially decreases cleaning effectiveness and, thus, increases the chance for thrush. This study explored the relationship between the number of bottle parts and cleaning methods for bottle-fed-only infants (<13 months) presenting with oral candidiasis. After obtaining demographic information on eligible infants (via parental consent) from the chart, caregivers of 60 infants verbally completed a questionnaire. The questionnaire elicited information about the preferred bottle for feeding, number of parts, washing frequency, washing method, drying method, sterilization frequency, and sterilization method. The χ2 test, and Fisher's exact test when necessary, was performed to examine the relationship between each reported cleaning method (washing, drying, and sterilization) compared with the number of bottle parts (≤3 or ≥4). The number of bottle parts showed no association with bottle cleaning methods (p > .05). Although there were no statistically significant relationships, trends did present that warrant investigation. Future studies to confirm recommended practices for cleaning methods and identify those at risk from demographic data could positively affect the health of bottle-fed infants by reducing the occurrence of thrush.

Multilevel modeling analysis of bottle feeding and its determinants among children 0-23 months in East Africa: evidence from recent DHS data (2015-2022).

BACKGROUND: Despite breastfeeding recommendations, the prevalence and length of breast milk feeding in developing nations is rapidly decreasing, with bottle feeding taking its place. This reduces the effectiveness of breastfeeding and is associated with diarrheal disease mortality and morbidity. The purpose of this study was to determine the prevalence, distribution, and determinants of bottle feeding among under-two-year-old children in the region. METHODS: The ten East African countries' Demographic and Health Surveys (DHS) recent data from 2015 to 2022 was used. The data were weighted using sample weights for probability sampling and nonresponse. The study used 43,150 weighted children. A multi-level logistic regression model was used, and P - values of ≤ 0.2 and < 0.05 were used to declare candidate variables in the binary, and multivariable to declare significant variables, respectively. RESULTS: The prevalence of bottle feeding among children under-two-years-old in East Africa was 10.08% (95% CI 9.79, 10.36), ranging from 4.04% (95% CI 3.56, 4.53) in Tanzania to 33.40% (95% CI 32.72, 34.08) in Kenya. High antenatal care communities (AOR 1.22; 95% CI 1.11, 1.35), mothers aged 25-34 years (AOR 1.17; 95% CI 1.06, 1.28), high wealth index communities (AOR 1.12; 95% CI 1.02,1.25), women who had at least one types mass media exposure (AOR 1.64; 95% CI 1.53, 1.77), women from communities with high level mass media exposure (AOR 1.36; 95% CI 1.23, 1.52), given first birth after teenage years (AOR 1.17; 95% CI 1.09, 1.26), having more than one health visit in the year (AOR 1.37; 95% CI 1.27,1.47), multiple children (AOR 1.46; 95% CI 1.22, 1.75) were associated with higher rates of bottle feeding. Whereas a primary education (AOR 0.51; 95% CI 0.47, 0.54), having 3-5 living children (AOR 0.86; 95% CI 0.79, 0.95), a rural setting (AOR 0.53; 95% CI 0.49, 0.58), and a long distance from health facilities (AOR 0.84; 95% CI, 0.78, 0.91) were associated with lower rates of bottle feeding. CONCLUSIONS: The overall prevalence of bottle feeding was moderate in East African countries. Improving the availability and accessibility of health facilities to mothers, utilizing maternal healthcare, and media exposure will contribute to a significant decrease in the inappropriate bottle feeding of children in East Africa.

Comparison of the Effect of Direct Breastfeeding, Expressed Human Milk, and Infant Formula Feeding on Infant Weight Trajectories: A Systematic Review.

Background: Formula and breastfeeding are known factors associated with infant weight trajectories. Evidence exploring the effect of expressed human milk feeding on infant weight in the community setting has not been well synthesized. Objectives: This systematic review examined (1) weight changes among infants fed expressed human milk and (2) differences in weight change between infants fed expressed human milk and infants fed at the breast or infant formula via bottle. Methods: A comprehensive search of the literature was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The quality of each study was appraised using the Joanna Briggs Critical Appraisal Tools. Results: A total of six studies met the eligibility criteria and included a total of 5,152 infants. The within-subject analysis identified only 31 infants strictly or predominantly fed expressed human milk. The between-subject analysis comparing expressed human milk feeding to the available comparison groups (formula-fed or direct at the breastfed) revealed that higher weight gains were observed in the weight trajectories among infants in the bottle or formula-fed conditions in four of the six included studies. Conclusions: Findings from the few studies included in this review found a difference in the infant weight gain patterns among expressed human milk-fed infants when compared with their respective feeding groups (directly breastfed or formula-fed). Further research is needed to corroborate these findings and elucidate the clinical significance of the differences in weight gain patterns observed across infant feeding groups.

Awareness and Support of Responsive Bottle Feeding Among WIC Counselors and Caregivers: A Formative Qualitative Study.

OBJECTIVE: To understand the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) counselor experiences discussing responsive bottle feeding during counseling and WIC participants' knowledge, understanding, and use of responsive bottle feeding. METHODS: Qualitative descriptive, semistructured interviews with 23 participants (8 WIC counselors and 15 WIC participants) were conducted online via Zoom. The WIC counselors and mothers of WIC-enrolled bottle-fed infants were recruited through a network of WIC clinics in North Carolina. Interviews were recorded, transcribed, and collaboratively analyzed using content analysis. RESULTS: The WIC participants received responsive infant feeding support from WIC counselors but often in the context of breastfeeding. WIC counselors provided valuable support for families but were challenged by limited training on responsive bottle feeding, balancing promoting breastfeeding with supporting mothers' feeding decisions, and time constraints. CONCLUSIONS AND IMPLICATIONS: Findings provide preliminary support for the need to develop and pilot an intervention focused on promoting responsive feeding for parents of bottle-fed infants.
