Abstract

he problem of inconsistent breast milk supply frequently affects postpartum mothers and can impact the effectiveness of exclusive breastfeeding. Breast milk production and secretion are influenced by physiological and psychological factors, as well as family support during the postpartum period. Oxytocin massage is a complementary therapy that can enhance milk ejection by stimulating the milk ejection reflex and promoting relaxation. This study aimed to examine the factors associated with the use of oxytocin massage on breast milk production among postpartum mothers on days 4–10 at the Amuntai Selatan Health Center. An observational analytic study using a cross-sectional approach was conducted from February to May 2026. The sample consisted of 40 postpartum mothers selected through purposive sampling. The independent variables were age, knowledge, education level, occupation, spousal support, and number of children, while the dependent variable was the implementation of oxytocin massage on breast milk production. Data were analyzed using the Chi-square test with a significance level of p<0.05. The results showed significant associations between age, knowledge, education, spousal support, and number of children and the use of oxytocin massage (p<0.05), while occupation was not significantly associated (p>0.05). Spousal support was the primary influencing factor.

Abstract

Uterine involution is a significant physiological process during the postpartum period, marked by a gradual reduction in uterine fundal height following childbirth. An inadequate decrease may increase the risk of postpartum complications, including uterine subinvolution and postpartum haemorrhage. Early mobilisation is a non-pharmacological strategy that can facilitate uterine involution. This study aimed to evaluate the effectiveness of early mobilisation in reducing uterine fundal height among postpartum mothers on days 1–3 at Babirik Health Center. A quasi-experimental design with a pretest-posttest approach was employed from February to May 2026. The sample consisted of 12 respondents, including 6 in the intervention group and 6 in the control group, selected through purposive sampling. Uterine fundal height was measured using a measuring tape, while early mobilisation was implemented progressively from 6–8 hours postpartum. Data were analysed using the Paired t-test and independent t-test with a significance level of p<0.05. The results showed that the mean uterine fundal height in the intervention group decreased from 11.2 cm before intervention to 3.1 cm after intervention. The control group showed a more gradual decline. Statistical results showed p-values of 0.000 and 0.001 (p<0.05), indicating that early mobilisation effectively reduces uterine fundal height. Early mobilisation is a safe and simple non-pharmacological strategy to accelerate uterine involution and support postpartum recovery.

Abstract

Background: Early Initiation of Breastfeeding (EIBF) is a research-supported practice that promotes successful lactation and increases the likelihood of exclusive breastfeeding. Skin-to-skin contact and breastfeeding within the first hour after birth stimulate hormonal responses that support milk production and strengthen maternal-infant bonding. This study aimed to determine the relationship between EIBF and the success of exclusive breastfeeding among postpartum mothers in the maternity ward of Paradise Mother and Child Hospital. Methods: This observational study used a cross-sectional design involving 50 postpartum mothers with infants aged 6–12 months, selected through sequential sampling. EIBF data were obtained from medical records and Maternal and Child Health (MCH) handbooks, while exclusive breastfeeding data were collected through structured interviews using a validated questionnaire. Data were analysed using the Chi-square test with a 95% confidence level. Results: Most mothers practiced EIBF (68.0%), and 72.0% successfully provided exclusive breastfeeding for the first six months. EIBF was significantly associated with successful exclusive breastfeeding (p=0.001). Conclusion: Early initiation of breastfeeding was significantly associated with successful exclusive breastfeeding. Strengthening EIBF implementation, breastfeeding education, and lactation support is important to increase exclusive breastfeeding rates and promote optimal maternal and infant health.

Abstract

Background: Preterm birth remains a leading cause of neonatal morbidity and mortality worldwide. Besides obstetric and maternal medical conditions, psychological factors, particularly maternal stress during pregnancy, may contribute to the risk of preterm birth through neuroendocrine mechanisms affecting pregnancy outcomes. This study aimed to examine the relationship between maternal stress levels and the risk of preterm birth among pregnant women at Maba Regional General Hospital, Maba District, East Halmahera Regency. Methods: This analytical observational study used a cross-sectional design and was conducted from March to May 2026. A total of 75 pregnant women were selected using total sampling. Maternal stress was assessed using the Perceived Stress Scale (PSS-10), while the risk of preterm birth was determined based on obstetric risk factors documented in medical records. Data were analysed using descriptive statistics and the Chi-square test with a 95% confidence level. Results: Most respondents experienced moderate stress (41.3%), while 26.7% experienced high stress. A high risk of preterm birth was identified in 38.7% of participants. Pregnant women with high stress levels were more likely to have a high risk of preterm birth. The Chi-square test showed a significant association between maternal stress level and preterm birth risk (p=0.001). Conclusion: Maternal stress during pregnancy was significantly associated with increased preterm birth risk. Integrating mental health screening, psychological counselling, and stress management into antenatal care may help reduce this risk and improve maternal and neonatal health outcomes

Abstract

Background: The Maternal and Child Health (MCH) Handbook is an important educational tool for improving pregnant women's knowledge of maternal health, particularly their ability to recognize pregnancy danger signs. Adequate understanding of its content and benefits may support early detection of complications and timely access to appropriate healthcare. This study aimed to examine the relationship between mothers' knowledge of the MCH Handbook and their ability to recognize pregnancy danger signs among first-trimester pregnant women at Damuli Primary Health Center. Methods: This analytical observational study employed a cross-sectional design and was conducted from March to May 2026. A total of 35 first-trimester pregnant women were selected using total sampling. Knowledge of the MCH Handbook and the ability to recognize pregnancy danger signs were assessed using structured questionnaires. Data were analyzed using descriptive statistics and the Chi-square test with a 95% confidence level. Results: Most respondents demonstrated good knowledge of the MCH Handbook (40.0%) and good ability to recognize pregnancy danger signs (60.0%). Mothers with good knowledge were more likely to correctly recognize pregnancy danger signs than those with moderate or poor knowledge. The Chi-square test showed a significant relationship between MCH Handbook knowledge and the ability to recognize pregnancy danger signs (p=0.002). Conclusion: Knowledge of the MCH Handbook was significantly associated with the ability to recognize pregnancy danger signs. Continuous health education during antenatal care is essential to strengthen its utilization and support early detection of pregnancy complications.

Abstract

Background: Stunting remains a significant public health concern in Indonesia because of its long-term effects on children's physical growth, cognitive development, and future human capital. Exclusive breastfeeding during the first six months of life is a primary strategy to prevent stunting. Breast milk provides optimal nutrients and bioactive components that support healthy growth, strengthen immunity, and promote infant development. This study aimed to investigate the relationship between exclusive breastfeeding and stunting among children under five years of age in the working area of Damuli Primary Health Center, Patani Timur District, Central Halmahera Regency. Methods: This observational study employed a cross-sectional design and was conducted from March to May 2026. The sample consisted of 50 mothers with children aged 24–59 months, selected using total sampling. Data on exclusive breastfeeding history were collected through structured interviews using a questionnaire, while stunting status was assessed based on height-for-age according to the World Health Organization (WHO) Child Growth Standards. Data were analyzed using descriptive statistics and the Chi-square test with a 95% confidence level. Results: Most children were exclusively breastfed and were not classified as stunted. Exclusively breastfed children had a lower incidence of stunting than those who were not exclusively breastfed. The Chi-square test showed a significant relationship between exclusive breastfeeding and stunting (p=0.001). Conclusion: Exclusive breastfeeding was significantly associated with stunting among children under five. Promoting exclusive breastfeeding, growth monitoring, and nutritional education should remain priorities in stunting prevention efforts.
