Abstract

Preeklampsia merupakan komplikasi kehamilan yang kompleks dan multifaktorial, dengan salah satu faktor risiko potensial berasal dari paparan logam berat, khususnya timbal (Pb). Penelitian ini bertujuan untuk menganalisis hubungan antara kadar timbal dalam darah dengan kejadian preeklampsia pada ibu hamil. Desain penelitian adalah analitik observasional dengan rancangan case control yang melibatkan 66 responden, terdiri dari 33 ibu hamil dengan preeklampsia dan 33 ibu hamil normotensi. Pemilihan sampel dilakukan secara purposive sampling dengan kriteria inklusi usia kehamilan ≥28 minggu dan tanpa riwayat penyakit kronis. Kadar timbal darah diukur menggunakan metode Atomic Absorption Spectrophotometry (AAS). Data dianalisis menggunakan uji Mann-Whitney dengan tingkat kemaknaan α=0,05. Hasil penelitian menunjukkan rata-rata kadar timbal darah sebesar 19,33 ± 8,21 µg/dL (rentang 6,50–31,75 µg/dL). Uji statistik menunjukkan perbedaan signifikan antara kelompok preeklampsia dan kontrol (p=0,000), dengan kadar timbal lebih tinggi pada kelompok preeklampsia. Temuan ini mendukung hipotesis bahwa paparan timbal, bahkan pada kadar rendah, berkontribusi terhadap patogenesis preeklampsia melalui mekanisme stres oksidatif, kerusakan endotel, dan penurunan nitric oxide. Disarankan pemeriksaan kadar timbal sebagai bagian dari skrining risiko preeklampsia di daerah dengan potensi paparan logam berat tinggi. Kata kunci: timbal, preeklampsia, kehamilan, logam berat, stres oksidatif

Abstract

Stunting is a chronic nutritional problem with long-term consequences for human capital and is influenced by nutritional conditions across the life course, including adolescence as a critical preconception period. Adolescent girls play a strategic role in intergenerational stunting prevention; however, nutrition literacy in this group remains relatively low. This study aimed to analyze the effect of nutrition education on improving nutrition knowledge among adolescent girls as a preventive strategy for intergenerational stunting among senior high school students.A quasi-experimental study with a one-group pretest–posttest design was conducted. The study participants consisted of 100 female students in grades X and XI from a senior high school in Rumbai, Indonesia, selected using a total sampling technique. Data were collected using a structured nutrition knowledge questionnaire that had been tested for validity and reliability. Data analysis included univariate and bivariate analyses. Normality was assessed using the Shapiro Wilk test, and differences in nutrition knowledge scores before and after the intervention were analyzed using a paired t-test with a significance level of p < 0.05.The mean nutrition knowledge score increased significantly from 65.42 ± 6.12 before the intervention to 81.30 ± 6.05 after the intervention (p < 0.001). A mean difference of 15.88 points indicates a substantial improvement in nutrition knowledge following the nutrition education program. In conclusion, nutrition education is effective in improving nutrition knowledge among adolescent girls and has the potential to serve as an upstream preventive strategy for intergenerational stunting.

Abstract

Breast milk production is one of the major determinants of successful exclusive breastfeeding during the early postpartum period. Insufficient milk production often leads to early breastfeeding discontinuation and the introduction of infant formula. This study aimed to determine the effectiveness of Woolwich Massage on breast milk production based on both maternal and infant indicators among postpartum mothers. A quasi-experimental study with a pretest–posttest control group design was conducted at BPM Sasyuni, Kampar Regency, Indonesia, from January to March 2026. Thirty postpartum mothers were recruited using consecutive sampling and equally assigned to an intervention group (n = 15) and a control group (n = 15). Breast milk production was assessed using maternal indicators (breast fullness, breast softening, spontaneous milk leakage, let-down reflex, and absence of breast engorgement) and infant indicators (urination frequency, bowel movement frequency, infant satisfaction, sleep duration, and weight gain). The paired t-test revealed a significant increase in breast milk production scores in the intervention group (mean difference = 5.13 ± 0.99; p < 0.001), while the independent t-test demonstrated significantly greater improvement than the control group (p < 0.001). These findings suggest that Woolwich Massage is an effective, safe, and low-cost non-pharmacological intervention that can be integrated into routine postpartum midwifery care to support successful exclusive breastfeeding.
