The prevalence of short inter-pregnancy interval and its associated risk factors among women attending primary health care centers of NGHA in Jeddah, Saudi Arabia: A cross-sectional study.

The inter-pregnancy interval (IPI) refers to the time between one pregnancy and the next. Studies have shown that IPIs shorter than 18 months are linked to negative outcomes, such as preterm delivery, infant mortality, and small-for-gestational-age birth. The aim of this study was to measure the prevalence and risk factors of short inter-pregnancy intervals among women receiving care at primary health centers in Jeddah, Saudi Arabia. This is a cross-sectional study conducted at primary health care centers among mothers with a history of giving birth to at least one child and having two successive pregnancies. The data was collected through face-to-face interviews using a structured questionnaire. Statistical analysis was carried out using RStudio (R version 4.3.0). A total of 300 responses were analyzed. The prevalence of short IPI was 36.0%, 31.0% had prolonged IPI, and 33.0% had optimal IPI. Lower educational level, unemployment as a student, low or middle income, a rise in the number of children, typically more than six, and an increase in the number of male offspring, mostly four or more, lack of breastfeeding, and breastfeeding duration have all been identified as statistically significant risk factors for short IPIs. Short inter-pregnancy interval is prevalent in Jeddah city, which can negatively impact the perinatal outcomes. Addressing the risk factors and providing proper education in antenatal and postnatal clinics to reduce the number of unintended pregnancies can help in decreasing the number of short inter-pregnancy intervals and improving maternal and fetal outcomes.

Social Desirability Bias in a Randomized Controlled Trial That Included Breastfeeding Promotion in Western Kenya

BackgroundBreastfeeding promotion is associated with improved measures of breastfeeding practice; however, most studies rely on participant-reported outcomes. ObjectivesThis study aimed to evaluate the likelihood of bias in self-reported breastfeeding outcomes. MethodsWe used data from the WASH Benefits randomized controlled trial in Kenya (clinicaltrials.gov NCT01704105), which included intervention arms that received infant and young child feeding messages (nutrition group) and arms that did not (non-nutrition group) to examine recall bias in the assessment of early initiation of breastfeeding (EIBF) and exclusive breastfeeding (EBF) duration. Pregnant women were eligible for inclusion, but 40% of infants were born before the first visit by the health promoter. We used the random variability in the timing of the infant birth relative to the first contact with the health promoter to examine recall bias in EIBF. We used ≤5 rounds of repeated surveys to examine bias in recall of EBF duration. ResultsThere was a significant effect of the intervention group on EIBF [prevalence ratio: 1.50, 95% confidence interval (CI): 1.43, 1.57] and a significant difference in the duration of EBF [nutrition group: 6.0 mo; interquartile range (IQR): 3.0–6.0; nonnutrition group: 3.0 mo; IQR: 0.5–6.0; P < 0.001]. There was not a significant interaction with birth timing relative to the first contact with the health promoters (P = 0.915), suggesting that the observed main effect on EIBF was due to recall bias. We found that 75.9% of mothers who initially reported having ceased EBF before 6 mo in the nutrition group changed their response to 6 mo or later in subsequent surveys. Only 32.5% of mothers in the non-nutrition group followed this pattern. ConclusionsThese data provide strong evidence of bias in reporting of breastfeeding practices in this nonblinded intervention trial and should serve as a caution to researchers who rely on self-reported outcomes of behavior change interventions.This trial was registered at clinicaltrials.gov as NCT01704105.

Factors affecting early initiation of breastfeeding among mothers of urban area of Jabalpur district, Madhya Pradesh, India: A community-based cross-sectional study.

Early initiation of breastfeeding reduces infant mortality and morbidity and prolongs the duration of breastfeeding. The present study was conducted to assess the prevalence of early initiation of breastfeeding and factors associated with early initiation of breastfeeding in the urban area of Jabalpur district of Madhya Pradesh. The present community-based cross-sectional study was conducted in an urban area of Jabalpur district of Madhya Pradesh from March 2017 to July 2018 on 370 recently delivered mothers. Data were collected by interview, using the pretested structured questionnaire and analyzed using SPSS, version 20. Significance was set at the value of P < 0.05. The prevalence of early initiation of breastfeeding was found to be 45.4%. The percentage of mothers initiating breastfeeding earlier increased when they belonged to the higher age group, nuclear family, were educated, employed, counseled during antenatal visits, non-primigravida and delivered in health institutions. It was also observed that type of delivery, socioeconomic status of mothers, birth weight of baby and occupation of husband are not significantly associated with the early initiation of breastfeeding. Increasing literacy amongst the population, promoting marriages at an appropriate age, counseling pregnant women regarding early initiation of breastfeeding during antenatal care visits and institutional deliveries can significantly increase the prevalence of early initiation of breastfeeding in the mothers of urban areas of Jabalpur district, Madhya Pradesh.

Father Support, Postpartum Depression, and Breastfeeding Weaning Time: A Structural Equation Model

Background: Fathers play a crucial role in family well-being beyond financial support, positively influencing the health of both mothers and infants through involvement in childcare, prenatal care, and emotional support during pregnancy and childbirth. However, research on the long-term effects of father involvement in during prenatal and its postpartum outcome, particularly in Indonesia, is limited.Purpose: This study aimed to measure the direct and indirect effects of father support throughout pregnancy on postpartum depression and breastfeeding weaning time, by considering potential mediating pathways and controlling for relevant sociodemographic variables.Methods: Prospective observational techniques were employed from January to July 2021, involving 648 consecutively selected mothers attending antenatal care in seven health clinics in Makassar. Data collection included meticulous adherence to protocols covering sociodemographic factors, father support, and breastfeeding weaning time. Father support was assessed with the Father Support During Pregnancy questionnaire, administered three times with a 72-hour interval. Postpartum depression was measured using the Edinburgh Postnatal Depression Scale, while breastfeeding weaning time was quantified in weeks. Analysis included Spearman's correlation and SEM using SPSS and SPSS Amos.Result: The study identified negative correlations between maternal breastfeeding weaning time and postpartum depression (r=-0.183, p&lt;0.01), and positive correlations with father support (r=0.148, p&lt;0.01), parity (r=-0.269, p&lt;0.01), and marital age (r=0.187, p&lt;0.01). In the standardized model showed a marginal rise in the overall influence of father support, parity, and marital age on breastfeeding weaning time (0.256, 0.016, and 0.123, respectively). Father support emerged as the primary contributor to postpartum depression, inversely impacting breastfeeding duration. Higher father support correlated with lower maternal depression scores, and longer.Conclusion: This study highlights the role of father support in reducing the impact of postpartum depression on breastfeeding duration. Nurses can contribute by participating in interdisciplinary research and advocating for comprehensive assessment approaches.

The effects of duration of any breastfeeding on body mass index in Australian children: Exploration of health, economic and equity impacts.

Breastfeeding is a protective measure against childhood overweight and obesity. However, many children are not breastfed the recommended duration, with those from disadvantaged backgrounds more likely to cease breastfeeding early. Investigate the association between duration of any breastfeeding and body mass index (BMI) and estimate the health, economic and equity impacts of increasing breastfeeding duration to at least 6 months. We modelled the association between any breastfeeding duration and BMI at age 6/7 years, using a nationally representative cohort of 3935 Australian children (survey weighted to 221 103 children). We then used a simulation model to predict the impact of increasing breastfeeding duration to at least 6 months in all children on prevalence of overweight (including obesity) and associated healthcare costs to age 16/17 years. Achieving breastfeeding duration of at least 6 months could prevent 2933 cases of overweight at age 16/17 years, translating to healthcare cost-savings of AUD $4.29 million. Although most cases (68%) would come from low socio-economic backgrounds this would make only a minor difference in reducing inequalities. Efforts to support increased breastfeeding duration could result in reduced prevalence of overweight and obesity and save healthcare costs, however, additional action would be required to improve equity.

Association of Hormonal Exposures With Grip Strength in Women >45 Years: Data From the CONSTANCES Cohort Study.

Although biological findings show that estrogens are beneficial for muscular mass maintenance and bone resorption inhibition, the association of hormonal exposure with physical performance are controversial. We investigated the association of reproductive history and exogenous hormone use with hand-grip strength (GS) in women. Using the data from the CONSTANCES French prospective population-based cohort study, we ran linear mixed models to investigate the association of reproductive history and exogenous hormones use with maximal GS in 37 976 women aged 45 to 69 years recruited between 2012 and 2020. We used multiple imputation by chained equations to control missing values and corrections for multiple testing. The mean age of women was 57.2 years. Mean GS was 26.6 kg. After adjustment for age and confounders, GS increased with age at menarche (β+1 year = 0.14; 95% CI, 0.10-0.17) and duration of breastfeeding (β for ≥10 months vs <5 months = 0.39; 95% CI, 0.20-0.59; P for linear trend <.01). Compared to nonmenopausal women, postmenopausal women had significantly lower GS (β = -0.78; 95% CI, -0.98 to -0.58). GS was negatively associated with hormone therapy (HT) past use (β = -0.25; 95% CI, -0.42 to -0.07). Our results suggested that menopausal transition was strongly associated with lower GS. However, despite our hypothesis, increased age at menarche and duration of breastfeeding were associated with higher GS and HT past users presented lower GS than HT never users. These findings could help identify women at high risk of poor physical performance.

A long-term study of stable isotope ratios of fingernail keratin and amino acids in a mother-infant dyad.

To evaluate the potential of compound-specific isotope analysis of amino acids (CSIA-AA) for investigating infant feeding practices, we conducted a long-term study that compared infant and maternal amino acid (AA) nitrogen isotope ratios. Fingernail samples were collected from a single mother-infant dyad over 19 months postpartum. Carbon and nitrogen stable isotope ratios were measured in the bulk keratin of the fingernail samples. Selected samples were then hydrolyzed and derivatized for compound-specific nitrogen isotope analysis of keratin AAs. As in previous studies, infant bulk keratin nitrogen isotope values increased during exclusive breastfeeding and fell with the introduction of complementary foods and eventual cessation of breastfeeding. Infant trophic AAs had elevated nitrogen isotope values relative to the mother, while the source AAs were similar between the mother and infant. Proline and threonine appeared to track the presence of human milk in the infant's diet as the isotopic composition of these AAs remained offset from maternal isotope values until the cessation of breastfeeding. Although CSIA-AA is costly and labor intensive, it appears to hold potential for estimating the duration of breastfeeding, even after the introduction of complementary foods. Through the analysis of a full suite of AAs, it may also yield insights into infant physiology and AA synthesis.

The Impact Of Endorphin Massage On The Efficient Production Of Postpartum Breast Milk In TPMB Sulastri, Pagelaran District, Pringsewu Regency In 2024.

Initiating breastfeeding within the first day of delivery has been shown to decrease the likelihood of newborn mortality. It is specifically demonstrated to provide exclusive protection against diarrhea, respiratory infections, and pneumonia ASI. The project seeks to investigate endorphin massage's impact on smoothness development in postpartum women at TPMB Sulastri, S.ST., M.Kes in 2024.ASI stands for Automatic Speech Recognition. This research employs a quasi-experiment design utilizing a pretest-posttest control group strategy. The sample included of 14 participants in the intervention group and 14 participants in the control group. Purposive sampling techniques were employed. The instrument utilizes Standard Operating Procedures (SOP) and checklist sheets. A three-day Endorphin massage treatment was administered and assessed using the Mann-Whitney test. The study found that 50% of individuals had a moderate frequency of meal intake. The utilization rate of non-hormonal contraceptives was 71.4%. The weight of newborns does not exceed 100% of the BBLR. The gestational age at the time of labor is 100% accurate. The mean milk output of the intervention group was 2.6 before and 7.5 after. The mean of the control group was 2.5 before and 5.2 after. The endorphin massage significantly impacted the efficient production of breast milk in postpartum moms. This was evidenced by a p-value of 0.000 (&lt; 0.05) and a positive Correlation Coefficient value of 0.88, indicating a highly robust association between the two variables. Ultimately, endorphin massage has a significant impact on facilitating the efficient production of breast milk in mothers throughout the postpartum period. It is desirable for lactating postpartum women to regularly engage in endorphin massage to ensure the continuous and unobstructed flow of breast milk during the entire two-year duration of breastfeeding.

Longer skin-to-skin contact after birth enhances breastfeeding quality and duration: A cohort study.

Skin-to-skin contact (SSC) immediately after birth may improve breastfeeding outcomes. This study explored the effect of the duration of SSC in the delivery room on breastfeeding quality and duration. In this prospective observational cohort study, mother-infant pairs practising SSC were categorised into two groups based on SSC duration (≤45 or >45 min). Outcomes included breastfeeding quality in the delivery room and at 24 h of age assessed by the Infant-Breastfeeding Assessment Tool (IBFAT) score, and long-term breastfeeding duration up to 6 months while accounting for potential confounding variables. The study included 72 mother-infant pairs. SSC for more than 45 min was significantly correlated with longer immediate breastfeeding (65 vs. 19 min, p < 0.001) and higher breastfeeding quality scores immediately after birth (IBFAT score of 10 vs. 7, p < 0.001). Regarding the long-term effect, infants in the extended SSC group were breastfed longer (5.2 vs. 3.7 months, p = 0.005) and had exclusive breastfeeding (4.7 vs. 2.7 months, p > 0.001). No significant confounding variables were identified. Extended SSC (>45 min) correlated with prolonged, higher-quality breastfeeding after birth and longer successful breastfeeding.

Current Evidence on Nutrient Intakes and Infant Growth: A Narrative Review of Baby-Led Weaning vs. Conventional Weaning.

Throughout infancy, changes in growth and development are observed, including changes in nutritional requirements; at approximately 6 months of age, when complementary feeding begins, breastmilk and/or formula are no longer the sole source of energy and nutrients. Little is known about the impact of complementary feeding (CF) approaches used during this time on infant nutrition and growth. Baby-led weaning (BLW) has continued to gain popularity over the last two decades, emphasizing the importance of examining the adequacy of different CF methods. This narrative review of 19 studies from January 2010 to April 2024 aims to discuss the differences between BLW and conventional weaning (CW). The definition of BLW varied across studies, and no standard definition has been established. Though no differences in energy were reported, macronutrient and micronutrient intakes were variable between approaches, including for micronutrients such as iron and zinc. Of the few studies with growth data, results comparing BLW and CW were conflicting. Differences were seen in the demographics of parents who chose to follow BLW and breastfeeding prevalence and duration prior to complementary feeding. Additional research is needed to understand the impacts of BLW and CW on nutrient intakes and growth to inform recommendations for infant complementary feeding approaches.

Reliability and validity of the German version of the Iowa infant feeding attitude scale (IIFAS-G) and relations to breastfeeding duration and feeding method

BackgroundPublic health initiatives (e.g., the Baby Friendly Hospital Initiative) have led to an increase in breastfeeding rates worldwide. However, as (exclusive) breastfeeding duration is still below WHO recommendations, it is crucial to understand the factors that influence decisions on breastfeeding practice. Modifiable psychological factors such as intention to breastfeed have therefore become targets of recent interventions. As the intention to breastfeed is among the strongest predictors of breastfeeding duration, reliable tools for measuring the intention to breastfeed are needed. The Iowa Infant Feeding Attitude Scale (IIFAS) measures attitudes towards infant feeding and is used in various languages and across different cultural contexts. However, there has been no German version of the IIFAS (IIFAS-G) so far. The aim of this study was to investigate reliability, validity, and associations of the IIFAS-G with feeding method and breastfeeding duration.MethodsBetween August and November 2022, a total of 353 mothers (Mage = 35 years, SDage = 4.2 years) of singleton infants (47.3% female (1 undetermined), Mage = 10.8 months, SDage = 4.7 months, age range: 3-547 days; 90.4% living in Switzerland) participated in an online survey. The IIFAS-G was administered as a part of a larger study on early child development and infant feeding method.ResultsThe translated IIFAS-G showed unsatisfactory model fit for the two factor 17-item solution. Four items showed low factor loadings. After item reduction, a 13-item two factor solution showed satisfactory model fit (CFI = 0.92, TLI = 0.90, RMSEA = 0.07) and high internal consistency (Cronbach’s α = 0.85). The IIFAS-G score was higher for mothers who exclusively breastfed their infants compared to mothers who additionally or exclusively fed infant formula. Moreover, mothers with higher IIFAS-G scores were less likely to stop breastfeeding their child over the course of 1.5years (HR = 0.87).ConclusionA shorter two-factor IIFAS-G is proposed to investigate attitudes towards breastfeeding and formula feeding in German-speaking mothers.

Factors associated with stunting among children 0-23 months in Aceh: A cross-sectional study using SSGI 2021

Stunting is a chronic health problem that affects children and has long-term implications for cognitive development. The multifactorial causes of stunting require the identification of the most dominant factors to facilitate effective interventions. This study aimed to analyze the factors associated with stunting in children under two years old in Aceh. This was a cross-sectional study involving 2,395 subjects aged 0-23 months. Data were obtained from the 2021 SSGI national survey, consisting of stunting prevalence, child and family characteristics, household sanitation, universal health insurance ownership, breastfeeding and complementary feeding practices, immunization status, parenting and pregnancy classes, supplementary feeding, and food security. Logistic regression analysis was performed with 95% confidence intervals. The results showed a significant association between stunting and child sex, sanitation conditions, parental education, exclusive breastfeeding, complementary feeding practices, immunization status, micronutrient supplementation, and breastfeeding duration (p&lt;0.05). In conclusion, the factors associated with stunting in children aged 0-23 months in Aceh are sanitation, parental education, exclusive breastfeeding, complementary feeding practices, immunization, micronutrient supplementation, and duration of breastfeeding. This study highlights the importance of improved nutrition education, family support, increased immunization coverage, and improved environmental sanitation to reduce the prevalence of stunting among young children in Aceh.

Reproductive factors and risk of cardiovascular outcomes in women with ST-elevation myocardial infarction

BackgroundThere are many sex-specific factors affecting myocardial infarction (MI) outcomes in males and females. This study aimed to evaluate the relationship between reproductive factors and cardiovascular outcomes in women after ST-elevation MI.MethodThis retrospective cohort study was initiated in 2016–2017 at Chamran Hospital, Isfahan, Iran. One hundred eighty women with a diagnosis of ST-elevation MI were followed up for 3 years, and any occurrence of cardiovascular events (CVs) was recorded. All information regarding reproductive factors was recorded via questionnaire. This information was compared between women with cardiovascular events and women without adverse events using a sample t test, chi-square test, and multiple backward logistic regression analysis. SPSS version 24 was used to conduct all analyses.ResultSixty-four women with a mean age of 65.81 ± 13.14 years experienced CV events, and 116 women with a mean age of 65.51 ± 10.88 years did not experience CV events. A history of ischemic heart disease and diabetes mellitus were more prevalent in women with CV events (P = 0.024 and P = 0.019). After adjusting for ischemic heart disease and diabetes mellitus, oral contraceptive pill (OCP) usage was more prevalent in women with CV events than in women without CV events (60.9% vs. 40.4%, P = 0.008). There was a greater chance of CV events in women with OCP usage (OR = 3.546, P = 0.038) and a lower chance of CV events in women with greater age at menarche (OR = 0.630, P = 0.009) and longer breastfeeding duration (OR = 0.798, P = 0.041) according to multiple backward logistic regression models.ConclusionBased on this study, OCP consumption is a risk factor, while older age at menarche and longer duration of breastfeeding are protective factors for cardiovascular outcomes in women after STEMI.

Intimate Partner Violence and Breastfeeding Outcomes Among Canadian Women: An Exploratory Correlational Study.

Human breastmilk is the optimal nutrition for infants; however, preliminary research suggests that women who experience intimate partner violence (IPV) are less likely to initiate and continue breastfeeding. Self-efficacy is a known facilitator to achieve positive breastfeeding outcomes. This study aimed to explore the relationship between experiencing IPV and breastfeeding duration, exclusivity, and self-efficacy for Canadian mothers, and to identify potential variables that influence breastfeeding decision-making among women with experiences of IPV. This was a cross-sectional secondary analysis of surveys completed by 129 mothers with children under the age of 2 years from Ontario, Canada. Data were stratified according to those who had experienced IPV and those who had not. Breastfeeding outcomes assessed included breastfeeding self-efficacy and breastfeeding duration and exclusivity. Non-parametric tests and correlations were used to determine if relationships existed between IPV and breastfeeding outcomes. 72.3% (n = 94) of women in this sample breastfed their child(ren). Experiencing IPV was associated with lower breastfeeding self-efficacy scores (W = 768, p = 0.055) with a moderate effect size (r = 0.32 [95% 0.06,0.55]). This relationship was significant in the context of psychological abuse (W = 816.5, p = 0.015) with a small effect size (r = 0.22 [95% 0.03,0.41]). This study provides novel preliminary evidence suggesting that experiencing IPV of any type can negatively impact breastfeeding self-efficacy, with psychological abuse potentially being the most detrimental. Future research is required to build upon these findings.

Feeding-Related Early Signs of Autism Spectrum Disorder: A Narrative Review.

Feeding difficulties are prevalent among individuals with autism spectrum disorder (ASD). Nevertheless, the knowledge about the association between feeding-related early signs and child development remains limited. This review aimed to describe the signs and symptoms related to feeding during child development and to explore their relevance to the diagnosis of ASD. Specialists in nutrition and/or ASD conducted a search of MEDLINE, PsycINFO, and Web of Science databases. Although studies in typically developing children demonstrate age-related variations in hunger and satiety cues, the literature about early feeding indicators in ASD is scarce. Challenges such as shortened breastfeeding duration, difficulties in introducing solid foods, and atypical mealtime behaviors are frequently observed in children with ASD. The eating difficulties experienced during childhood raise concerns for caregivers who base their feeding practices on their perceptions of food acceptance or refusal. Considering the observed associations between feeding difficulties and ASD, the importance of recognizing feeding-related signs according to developmental milestones is emphasized to alert medical professionals that deviation in the formation of feeding habits and skills could indicate the need for ASD diagnostic investigation.

Academy of Breastfeeding Medicine Clinical Protocol #19: Breastfeeding Promotion in the Prenatal Period (Revised 2024).

Background: The Academy of Breastfeeding Medicine revised the 2015 version of this clinical protocol to review the evidence and provide recommendations related to breastfeeding promotion in the prenatal period. Key Information: Promoting and normalizing breastfeeding in the prenatal period can improve breastfeeding outcomes including initiation and duration of breastfeeding. Ideally, prenatal interventions should be a part of a comprehensive longitudinal breastfeeding support program. Recommendations: Clinicians or other health workers should discuss breastfeeding at each prenatal visit. Counseling topics should include the health benefits of breastfeeding versus not breastfeeding, the basics of breastfeeding (e.g., physiology, positioning), what to expect of hospital-based and immediate postpartum breastfeeding support (i.e., Baby-Friendly Ten Steps), and the risks of unnecessary supplementation. Medical, anatomical, and other risk factors for breastfeeding challenges should be identified, and targeted anticipatory guidance should be given. Prenatal counseling should include distribution of structured breastfeeding education at low literacy levels and in the parent's preferred language. Counseling should be culturally sensitive and patient-centered, including family members when appropriate. Prenatal support may integrate various health workers (e.g., medical doctors, midwives, community health workers, lactation consultants, among others) and include various modalities including telecommunication. Enhancing breastfeeding education for prenatal care providers is also imperative. Additional themes related to implementation of recommendations for specific populations are also reviewed.

Breastfeeding patterns in infants are associated with a later diagnosis of autism Spectrum disorder.

Breastfeeding is associated with medical and developmental benefits. This study aimed to assess associations between nutritional patterns in the first year of life and the likelihood of autism spectrum disorder (ASD). 270 children diagnosed with ASD (cases) and 500 neurotypical children (controls) matched to cases by sex, ethnicity, and birth date (± 3 months) were included in this retrospective case-control study. Both groups were ascertained from children born between 2014 and 2017 whose development/nutrition were monitored at mother-child health clinics in southern Israel. Conditional logistic regression was used to determine the independent association of nutritional patterns with ASD while adjusting for socio-demographic and clinical characteristics. Both exclusive and partial breastfeeding modes were associated with decreased odds of ASD diagnosis (aOR = 0.221, 95%CI = 0.136-0.360; aOR = 0.494, 95%CI = 0.328-0.743, respectively). A breastfeeding duration of >12 months was associated with lower ASD odds (aOR = 0.418, 95%CI = 0.204-0.855), while the introduction of solids after 6 months of age was associated with higher ASD odds than the introduction of solids at 6 months (aOR = 2.455, 95%CI = 1.116-4.201). These findings suggest that a longer period of exclusive breastfeeding is associated with a subsequent reduced likelihood of ASD diagnosis, thus reiterating the importance of proper post-natal nutrition for infant neurodevelopment.
