Abstract

Diabetes Mellitus (DM) is a non-communicable disease with an increasing global prevalence. Effective monitoring and management are essential to reduce disease burden and prevent complications, including through HbA1c assessment and nutritional status evaluation such as Body Mass Index (BMI) and Mid-Upper Arm Circumference (MUAC), which are feasible in primary health care settings. This study aimed to analyze the relationship between nutritional status and HbA1c levels among patients with Diabetes Mellitus at primary health centers in Kupang City. A cross-sectional design was conducted among 69 respondents selected using consecutive sampling at Oepoi, Sikumana, and Bakunase Primary Health Centers. Data were collected through BMI and MUAC measurements and HbA1c examination and analyzed using Pearson correlation test. The results indicated that most respondents were female, overweight based on BMI, had normal MUAC, and uncontrolled HbA1c levels. Statistical analysis showed no significant association between BMI and HbA1c levels (p > 0.05) nor between MUAC and HbA1c levels (p > 0.05). In conclusion, nutritional status was not significantly associated with HbA1c levels among DM patients. Glycemic control may be influenced by factors beyond anthropometric indicators.

Abstract

Primary dysmenorrhea ranks among the most prevalent menstrual issues in teenagers, impacting their everyday life and general well-being. The age at which menstruation begins has frequently been linked to the likelihood of experiencing dysmenorrhea; however, previous studies have produced mixed results. The goal of this research was to examine the connection between the age of menarche and the incidence of primary dysmenorrhea in female students at Kristen Citra Bangsa Mandiri Junior High School in Kupang. This investigation utilized an analytical observational method with a cross-sectional approach. A total of 54 students were chosen using purposive sampling according to specific inclusion and exclusion standards. Menarche age was classified as early (younger than 12 years), normal (12 to 14 years), and late (older than 14 years). The WaLIDD Score was employed to evaluate primary dysmenorrhea. The data were processed using the chi-square test, with a significance threshold set at p<0.05. The findings indicated that 55.6% of female students had a normal age for the start of menstruation, while 44.4% started early. The occurrence of primary dysmenorrhea was found to be 77.8%, with mild cases at 38.9%, moderate cases at 31.5%, and severe cases at 7.4%. Those who did not experience primary dysmenorrhea made up 22.2% of the respondents. The statistical analysis yielded a p=0.90 value. There was no significant link between the age of menarche and the prevalence of primary dysmenorrhea among students at Citra Bangsa Mandiri Christian Junior High School in Kupang City.

Abstract

Penggunaan obat antiinflamasi nonsteroid (OAINS) secara luas meningkatkan risiko gastritis melalui kerusakan mukosa lambung. Penelitian ini bertujuan mengevaluasi efek protektif ekstrak daun salam (Syzygium polyanthum) terhadap gambaran histopatologi mukosa lambung tikus Sprague Dawley yang diinduksi ibuprofen. Penelitian eksperimental laboratorik dengan desain posttest only with control group melibatkan 30 ekor tikus yang dibagi menjadi lima kelompok (n=6): kontrol negatif, kontrol positif (ibuprofen 100 mg/kgBB), serta tiga kelompok perlakuan yang menerima ibuprofen dan ekstrak daun salam dosis 50, 150, dan 250 mg/kgBB. Preparat lambung diperiksa pada perbesaran 400× untuk menilai deskuamasi, erosi, ulserasi, dan hiperplasia. Analisis menggunakan uji Kruskal–Wallis dan Mann–Whitney (α=0,05). Kontrol positif menunjukkan kerusakan mukosa berupa deskuamasi, erosi, dan hiperplasia. Kelompok perlakuan memperlihatkan perbaikan histologis dengan penurunan skor kerusakan, terutama pada dosis 250 mg/kgBB yang menurunkan skor sebesar 26,5% dibanding dosis lebih rendah. Terdapat perbedaan bermakna antar kelompok (p=0,000). Ekstrak daun salam menunjukkan efek protektif terhadap mukosa lambung akibat induksi ibuprofen.

Abstract

ABSTRACT Adolescence represents a transitional developmental stage characterized by significant physical, psychological, and social changes, which increase vulnerability to reproductive health problems. Inadequate levels of knowledge and unfavorable attitudes during this period may lead to various risky sexual behaviors, including premarital sexual intercourse, unintended pregnancy, and the transmission of sexually transmitted infections, including Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS). This study aimed to analyze the relationship between the level of knowledge and adolescents’ attitudes toward reproductive health among senior high school and vocational high school students in Kupang City. This study employed a quantitative approach with a cross-sectional design. The study population comprised all senior high school and vocational high school students in Kupang City at the selected research sites, with a total sample of 107 students selected using proportionate stratified random sampling and meeting the predefined inclusion and exclusion criteria. Data were collected using a structured questionnaire and analyzed through univariate and bivariate analyses using the Fisher–Freeman–Halton Exact Test with a significance level of p 0.05. The results showed that the majority of respondents had high to very high levels of knowledge and demonstrated positive attitudes toward reproductive health. Statistical analysis indicated a significant relationship between the level of knowledge and adolescents’ attitudes toward reproductive health (p = 0.001). This study concludes that the level of knowledge is significantly associated with adolescents’ attitudes toward reproductive health, highlighting the need to strengthen reproductive health education in schools to foster positive attitudes and healthy reproductive behaviors among adolescents. Keywords: Adolescents, Attitude and Knowledge, Reproductive Health, Kupang City.  ABSTRAK Remaja mengalami tahap transisi yang ditandai dengan berbagai perubahan fisik, psikologis, dan sosial yang signifikan, sehingga meningkatkan kerentanan terhadap permasalahan kesehatan reproduksi.
