ABSTRAKJumlah kasus osteoporosis cenderung mengalami peningkatan di Indonesia. Jawa Timur merupakan satu dari lima propinsi dengan risiko osteoporosis tertinggi di Indonesia. Penelitian bertujuan menganalisis perbandingan risiko osteoporosis menurut IMT, paritas, dan konsumsi kafein. Penelitian ini merupakan penelitian observasional analitik dengan desain kasus kontrol. Sampel kasus adalah wanita penderita osteoporosis berdomisili di Surabaya serta melakukan pemeriksaan osteoporosis di RSUD Dr. Soewandhie Surabaya tahun 2013-2014. Sampel kontrol adalah wanita bukan penderita osteoporosis berdomisili di Surabaya serta melakukan pemeriksaan osteoporosis di RSUD Dr. Soewandhie Surabaya tahun 2013-2014. Responden terdiri dari 45 kasus dan 45 kontrol diperoleh menggunakan metode simple random sampling. Data diperoleh melalui data primer dan sekunder. Variabel bebas adalah indeks massa tubuh, paritas, dan konsumsi kafein. Analisis dilakukan menggunakan perhitungan OR pada Epi info dengan tingkat kemaknaan 95% CI. Besar risiko tiap variabel adalah IMT (OR = 2,99; 95% CI = 1,16 < OR < 7,74), paritas (OR = 2,72; 95% CI = 1,07 < OR < 7,01), dan konsumsi kafein (OR = 2,41; 95% CI = 0,91 < OR < 6,42). Kesimpulan adalah wanita yang memiliki IMT < 18,5 berisiko terkena osteoporosis 2,99 kali lebih besar dibandingkan wanita yang memiliki IMT ≥ 18,5. Wanita yang memiliki paritas ≥ 3 kali berisiko terkena osteoporosis 2,72 kali lebih besar dibandingkan wanita memiliki paritas < 3 kali. Wanita yang mengonsumsi kafein ≥ 2 gelas/hari berisiko terkena osteoporosis 2,41 kali lebih besar dibandingkan wanita mengonsumsi kafein < 2 gelas/hari tetapi tidak signifi kan. Peneliti menyarankan agar wanita memiliki IMT normal dan membatasi jumlah kelahiran untuk mencegah terjadinya osteoporosis. (OR = 2,99; 95% CI = 1,16 < OR < 7,74), parity (OR = 2,72; 95% CI = 1,07 < OR < 7,01), and caffeine consumption (OR =2,41;95% CI = 0,91 < OR < 6,42 Kata kunci: risiko, osteoporosis, IMT, paritas, kafein ABSTRACT The number of osteoporosis tends to increase in Indonesia. East Java is one of fi ve provinces with the highest risk of osteoporosis in Indonesia. This study aims to analyze risk ratio of osteoporosis for women according to BMI

Foodborne diseases (FBDs) have a large disease burden among children. The major type of FBD in children is diarrhea, caused mainly by contaminated food. One of the diarrhea pathogens is Diarrheagenic Escherichia coli (DEC). The aim of this study was to establish a model of microbial prediction (DEC) in stool, caused by the transmission of FBDs in elementary schoolchildren. An observational analytic study was conducted, with a nested case-control study design. In Stage I, the study population was children in a selected elementary school at Surabaya. The sample size for Stage I was 218 children. In Stage II, the case sample was all children with a positive test for DEC (15 children), and the control sample was all children who had tested negative for DEC (60 children). The result of the laboratory tests showed that the proportion of DEC in children was 6.88% (15 of 218 children) and the proportion of Escherichia coli O157:H7 in children was only 0.46%. The most significant mode of transmission included in the model was the snacking frequency at school and the risk classification of food that was often purchased at school. The formulation of the predicting model of DEC in stool can be used as an early warning against the incidence of FBDs in elementary schoolchildren.

Typhoid fever is disease caused by Salmonella typhi bacteria transmission trought contaminated food and drink. Data from RSUD dr.

Data for case in this research are taken from medical record of ‘Unit Teratai’ for the past 1 year in RSUD dr. Abdoer Rahem Situbondo, whereas for control are case group. There are eighty person taken for this research as sample. This result was the risk of typhoid fever children which has habit of hand washing had after defecation at home OR 3.67 (1.29 < OR < 10.64), children which has habit of hand washing before eating had OR 4.33 (1.54 < OR < 12.44), children with short dirty fingernails had OR 7.79 (1.46 < OR < 46.18) frequent street food consumption OR 3.89 (1.39 < OR < 11.06), buy snack at food street OR 3.95 (1.40 < OR < 11.30), buy some snack with packing had OR 3.5 (1.26 < OR < 9.38).
