Background:The main nutritional problem in children under five, which is still found in many countries in the world, is stunting. The relationship between risk factors for low birth weight (LBW) in children has been investigated in several primary studies with a number of contradictions in the results. The purpose of this study was to determine the effect of low birth weight (LBW) on the incidence of stunting in children under 60 months in various countries using the meta-analysis method. Subjects and Method: The articles were selected from the Google Scholar, PubMed, Web of Science, Microsoft Academic, and Science Direct databases published from 2000-2021. Article collection for 2 months with search keywords ("Low Birth Weight" OR "LBW") AND "Stunting" AND ("adjusted odds ratio" OR "multivariable"). The meta-analysis step used is a PRISMA flowchart. Data analysis was carried out using the Review Manager 5.3 . program. Results: Based on 11 primary studies conducted in Brazil, Ethiopia, and Indonesia, it was shown that in a cross-sectional study LBW could increase the incidence of stunting in children aged 0-60 months by 3.64 times compared to non-LBW (aOR = 3.64; 95% CI = 2.70). up to 4.90; p<0.001). While the case-control study showed that LBW can increase the incidence of stunting in children aged 0-60 months as much as 6.95 times compared to non-LBW (aOR = 6.95; 95% CI = 4.02 to 12.04; p<0.001). Conclusion: Low birth weight increases the risk of stunting in the population of children under 60 months of age.

Perilaku merokok hingga saat ini masih menjadi perilaku yang sangat digemari oleh masyarakat di Indonesia. Dahulu merokok hanya dilakukan oleh orang dewasa namun saat ini banyak remaja yang sudah melakukan perilaku ini. Kurangnya pengetahuan dan sikap remaja terhadap dampak buruk rokok menjadi faktor remaja tetap mempertahankan perilaku merokok. Metode yang digunakan dalam kegiatan ini terdiri  dari tiga tahap yaitu pretest, penyuluhan secara online dengan menggunakan google meet dan postest. Berdasarkan olah data menggunakan aplikasi SPSS diperoleh hasil nilai sig <0,001 atau p<0.005 yang artinya terdapat perbedaan yang signifikan antara pengetahuan remaja sebelum dan setelah dilakukan penyuluhan secara online tentang bahaya merokok. Dengan demikian penyuluhan atau pemberian edukasi kesehatan dapat dikatakan efektif untuk meningkatkan pengetahuan remaja.

Objectives: The study investigated the association between indoor air pollution (IAP) and risk factors for acute respiratory infection (ARI) symptoms in children under 5 years of age.Methods: A cross-sectional study was conducted using data derived from Indonesia Demographic and Health Survey in 2017. Binary logistic regression modeling was employed to examine each predictor variable associated with ARI among children under 5 years of age in Indonesia.Results: The study included a total of 4936 households with children. Among children under 5 years old, 7.2% reported ARI symptoms. The presence of ARI symptoms was significantly associated with the type of residence, wealth index, and father’s smoking frequency, which were considered the sample’s socio-demographic characteristics. In the final model, living in rural areas, having a high wealth index, the father’s smoking frequency, and a low education level were all linked to ARI symptoms.Conclusions: The results revealed that households in rural areas had a substantially higher level of reported ARI symptoms among children under 5 years old. Furthermore, the father’s smoking frequency and low education level were associated with ARI symptoms.
