Abstract

Background : In 2010 within the area of Semarang Municipality, exclusive breastfeeding by mothers to their babies reaches  up to only 20,06%. One of the problems was the lack of lactation counseling especially by the health service institutions. Objectives: To reveal the effect of intensive lactation counseling on exclusive breastfeeding up to 3 months. Method: This research study was designed as a quasi-experiment of non-equivalent control group. The population of this study was a group of mothers who were in the 7th to 8th months of pregnancy bearing the second child or more. The number of the subjects was 25 mothers who were grouped into 2: the experimental groups of 12(n=12) and 27 control group of 13 (n=13). The group underwent a treatment of intensive lactation counseling of 9 times on 2 stages, the first was four-time treatments during the medical examination on their pregnancy of 7th – 8th months. The second stage of treatments was done by home visit for 5 times during week 1, 2, 4, 8, and 12 after giving birth by certified lactation counselors for 40 work hours. These counselors had the experience of at least 5 clients counseling. The control group had the usual counseling that they normally received from the midwives at the Health Primary Center and  private midwives nearby. Results: The group without intensive lactation counseling showed no gain of knowledge, attitude towards early initiation of breastfeeding, exclusive breastfeeding, breastmilk and no increase of the number of exclusive breastfeeding on their babies prior to and during the study. The group with intensive lactation breastfeeding shows a significant gain of knowledge, positive attitude towards early initiation of breastfeeding, exclusive breastfeeding, breastmilk and significant increase of the number of exclusive breastfeeding for 3 months on their babies that born prior to and during the study from 2(16,7%) to 10(83,3%). Conclusion: Intensive lactation counseling increases the practice of exclusive breastfeeding up to 3 months. Keywords : intensive lactation counseling, exclusive lactation breastfeeding, 3 months

Abstract

Diet rendah energi dan peningkatan aktivitas secara individual belum efektif dalam penurunan berat badan. Oleh karena itu, perlu dicari metode lain atau memodifikasi metode dengan membentuk kelompok peer group aktivitas. Tujuan penelitian ini menganalisis efektifitas aktivitas peer group terhadap kepatuhan aktivitas fisik, kepatuhan diet, penurunan berat badan dan persen lemak tubuh pada remaja overweight. Desain penelitian menggunakan Randomized Controlled Trial dengan rancangan eksperimental ulang pre-posttest control group design. Subjek penelitian adalah remaja putri overweight sebanyak 13 orang kelompok kontrol dan 13 orang kelompok perlakuan. Subjek dilakukan intervensi berupa jogging minimal 30 menit dan naik turun tangga sebanyak 10 kali per hari selama empat minggu. Ukuran kepatuhan diet diambil setiap minggu berdasarkan hasil recall 2x24 jam selama 4 minggu. Perbedaan kepatuhan aktivitas fisik dan kepatuhan diet diuji menggunakan Chi Square Test sedangkan perubahan berat badan dan persen lemak tubuh menggunakan ANOVA Repeated Measure Test. Ada perbedaan yang signifikan antara kepatuhan aktivitas fisik (p=0,000) dan penurunan berat badan (p=0,004) antara kelompok perlakuan dan kontrol namun tidak ada perbedaan yang signifikan antara kepatuhan diet (p>0,05) dan penurunan persen lemak tubuh (p=0,382) antara kelompok perlakuan dan kontrol. Peer group efektif dalam meningkatkan aktivitas fisik dan menurunkan berat badan pada remaja overweight.
