Bayi berat lahir rendah (BBLR) merupakan masalah kesehatan karena termasuk penyebab utama kematian neonatus di Indonesia selain karena dampak negatif jangka panjang yang disebabkannya. Konsumsi Tablet Tambah Darah (TTD) minimal 90 tablet selama kehamilan merupakan upaya menurunkan resiko kejadian BBLR. Namun kepatuhan konsumsi TTD pada ibu hamil di Indonesia masih rendah. Penelitian ini bertujuan untuk menganalisis hubungan kepatuhan konsumsi TTD pada ibu hamil dengan kejadian BBLR di Indonesia menggunakan data Survei Kesehatan Indonesia tahun 2023. Populasi penelitian ini adalah perempuan berusia 10-54 tahun di Indonesia berstatus kawin/cerai hidup/cerai mati yang memiliki riwayat persalinan periode 1 Januari 2018 sampai 25 September 2023, untuk kelahiran terakhir yang telah berakhir yang menjadi responden dalam SKI 2023. Sampel dalam penelitian ini adalah responden dari populasi penelitian yang memenuhi kriteria inklusi. Kriteria inklusi dalam penelitian ini adalah perempuan melahirkan bayi tunggal, informasi berat lahir bayi berdasarkan KIA, dengan data yang lengkap untuk semua variabel yang diteliti. Desain penelitian ini adalah cross sectional  dan menggunakan uji regresi cox dalam analisis data bivariat dan multivariat untuk mendapatkan Prevalence Ratio (PR) dengan interval kepercayaan 95%. Pendekatan analisis multivariat dilakukan untuk mengontrol variabel kovariat yaitu usia, pendidikan, pekerjaan, paritas, usia kehamilan, komplikasi kehamilan, merokok, kuantitas ANC K4,  kualitas ANC 10T, pola makan, status ekonomi, wilayah tempat tinggal dan jenis kelamin. Hasil penelitian ini menunjukkan proporsi BBLR sebesar 5,33% dan proporsi kepatuhan konsumsi TTD pada ibu hamil sebesar 49,02%. Hasil analisis multivariat menunjukkan hubungan yang signifikan secara statistik antara ibu hamil yang tidak patuh mengkonsumsi TTD dengan kejadian BBLR di Indonesia, dimana ibu hamil yang tidak patuh mengkonsumsi TTD mempunyai risiko 1,216 kali lebih besar (adjusted PR: 1,216; 95% CI: 1,04-1,43; p-value: 0,016) untuk melahirkan BBLR dibandingkan ibu yang patuh mengkonsumsi TTD, setelah dikontrol usia kehamilan Kepatuhan konsumsi TTD pada ibu hamil di masih rendah, padahal berhubungan signifikan dengan kejadian BBLR di Indonesia, sehingga perlu perhatian dari pemerintah untuk meningkatkan kepatuhan konsumsi TTD pada ibu hamil.

Low birth weight (LBW) is a health problem because it is one of the main causes of neonatal mortality in Indonesia in addition to the long-term negative impacts it causes. Consumption of Iron Supplement Tablets (TTD) of at least 90 tablets during pregnancy is an effort to reduce the risk of LBW. However, compliance with TTD consumption in pregnant women in Indonesia is still low. This study aims to analyze the relationship between compliance with TTD consumption in pregnant women and the incidence of LBW in Indonesia using data from the 2023 Indonesian Health Survey. The population of this study were women aged 10-54 years in Indonesia with married/divorced/divorced and died status who had a history of childbirth from January 1, 2018 to September 25, 2023, for the last birth that had ended who were respondents in the 2023 SKI. The sample in this study were respondents from the study population who met the inclusion criteria. The inclusion criteria in this study were women giving birth to a single baby, information on the baby's birth weight based on the KIA, with complete data for all variables studied. The design of this study was cross-sectional and used the cox regression test in bivariate and multivariate data analysis to obtain the Prevalence Ratio (PR) with a 95% confidence interval. The multivariate analysis approach was carried out to control covariate variables, namely age, education, occupation, parity, gestational age, pregnancy complications, smoking, quantity of ANC K4, quality of ANC 10T, diet, economic status, area of residence and gender. The results of this study showed a proportion of LBW of 5.33% and a proportion of compliance with TTD consumption in pregnant women of 49.02%. The results of the multivariate analysis showed a statistically significant relationship between pregnant women who were not compliant in consuming TTD and the incidence of LBW in Indonesia, where pregnant women who were not compliant in consuming TTD had a 1.216 times greater risk (adjusted PR: 1.216; 95% CI: 1.04-1.43; p-value: 0.016) of giving birth to LBW compared to mothers who were compliant in consuming TTD, after controlling for gestational age. Compliance with TTD consumption in pregnant women is still low, even though it is significantly related to the incidence of LBW in Indonesia, so the government needs attention to increase compliance with TTD consumption in pregnant women.

Anglz Bayi Bent Lahir Rendah (BBLR) di Indonesia maslh cukup tinggi. Keadaan BBLR meningkatkan risiko kematian dan kesakitan perinatal & bayi.

Abstract Low birth weight rate is still high. Low birth weight increased the risk of perinatal and infant mortality and morbidity. This study aims to know the relation between antenatal care (first visit, frequency, iron pill consumption) and low birth weight controlling for infant?s gender, maternal age, maternal education, parity, birth space and history of abortion. 5 The study design is unmatched case-control nsed Indonesia Demographic and Health Survey 1997 (IDHS 1997) data wherein 748 cases and 1496 controls were selected among singleton infants were carried out in IDHS 1997- This study found: the mother of cases have 1.29 times having first visit at the second or third trimester of pregnancy compared to the controls controlling for maternal age, maternal education and birth space. The mother of cases have 1.81 tlmes having visit frequency less than 4 times compared to controls controlling for maternal age and birth space. The mother of cases have 1.89 times having iron pill consumption less than 90 pill compared to the controls controlling for visit frequency, maternal age, maternal education and birth space. The attributable risk of first visit was 22.5 %, visit freqneudy was 44.8 % and iron pill consumption was 47.1 %. This study recommend: 1). to control for the availability and distribution of iron pill 2). to add other questions into IDRS questionnaire, eg. maternal blood tension, height, weight and anemia?s status 3). to give informations for girls and young mothers about the reproduction health with the main messages are marriage age/birth age and birth space 4). to analyze the last IDHS data.
