Abstract

Diarrhea remains one of the leading causes of morbidity and mortality among infants in Indonesia. Formula feeding is often associated with diarrhea, especially among infants under six months of age. Based on 2024 data from the Kupang City Health Office, Sikumana Public Health Center ranked second in diarrhea cases among children under five, with 1,376 reported cases. This study employed an analytical observational design with a cross-sectional approach. The population included all infants aged 0–6 months residing in the Sikumana Public Health Center area. A total of 120 infants were selected using a consecutive sampling technique according to inclusion and exclusion criteria. Data were collected through structured questionnaires administered to parents and verified with information from the Maternal and Child Health (KIA) book. Data were analyzed using the Chi-square test with a significance level of p<0.05. Among the 120 respondents, 21 infants (17.5%) received formula, while 99 infants (82.5%) did not receive formula. A total of 45 infants (37.5%) experienced diarrhea, and 75 infants (62.5%) did not. Data analysis indicated no meaningful connection between formula feeding and the occurrence of diarrhea (p = 0.352). There was no significant association between formula feeding and the rates of diarrhea in infants aged 0–6 months at the Sikumana Public Health Center located in Kupang City.

Abstract

The increasing number of elderly individuals in Indonesia each year is accompanied by a higher prevalence of degenerative diseases, including hypercholesterolemia. However, with advancing age, elderly individuals tend to experience a decline in functional capacity, leading to reduced physical activity. This study aimed to analyze the relationship between physical activity intensity and total cholesterol levels among elderly residents at the Kupang Elderly Social Welfare Technical Implementation Unit (UPTD) in 2025. This analytical study employed a cross-sectional design involving elderly residents of the Kupang Elderly Social Welfare UPTD. Data were examined through both univariate and bivariate analyses employing the Chi-square test with a significance threshold of p < 0.05. A majority of the respondents fell into the young elderly category (60–69 years) and were mostly women. The findings revealed that the greater part of older participants showed low intensity in physical activity while having elevated total cholesterol levels. The Chi-square analysis demonstrated a meaningful connection between the intensity of physical activity and total cholesterol levels (p < 0.05). These findings suggest that a decrease in physical activity intensity correlates with an increase in total cholesterol levels among seniors. A noteworthy relationship exists between physical activity intensity and total cholesterol levels in elderly individuals at Kupang Elderly Social Welfare UPTD. Regular and appropriately tailored physical activity serves as an important strategy to maintain lipid metabolism balance and prevent cardiovascular disease risks in the elderly population.

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

Central obesity and hypertension are major public health problems contributing substantially to the burden of non-communicable diseases. Excess saturated fat intake plays an important role in visceral fat accumulation and blood pressure elevation, particularly in populations with distinctive lifestyles and dietary patterns such as religious communities and monasteries. This study aimed to determine the association between saturated fat intake and central obesity as well as elevated hypertension among members of communities and monasteries of the Archdiocese of Ende. An observational analytic study with a cross-sectional design was conducted. A total of 50 respondents were selected using simple random sampling. Saturated fat intake was assessed using a Semi-Quantitative Food Frequency Questionnaire, central obesity was determined by waist circumference measurement, and elevated hypertension was identified through blood pressure assessment. Data were analyzed using the Chi-Square test with a significance level of α = 0.05. Most respondents had normal saturated fat intake (50.0%), followed by high intake (40.0%). Central obesity was observed in 72.0% of respondents, and 40.0% were classified as having elevated hypertension. Bivariate analysis demonstrated a significant association between saturated fat intake and central obesity (p = 0.001) as well as elevated hypertension (p = 0.009). There is a significant association between saturated fat intake and both central obesity and elevated hypertension among members of communities and monasteries of the Archdiocese of Ende.

Abstract

Diabetes melitus adalah  penyakit kronis berupa gangguan metabolik yang ditandai dengan  adanya kadar glukosa darah yang melebihi batas normal. Aloksan mengakibatkan kerusakan sel beta pankreas dengan cara mengaktifkan oksigen reaktif (ROS) yang dimulai oleh reaksi reduksi dari aloksan. Target dari ROS yaitu DNA dari sel pulau Langerhans pada pankreas. Daun bidara mengandung senyawa flavonoid, saponin, tanin dan fenolat sebagai antioksidan alami yang menetralkan dan menstabilkan radikal bebas dalam organ pankreas. Untuk mengetahui efek ekstrak daun bidara  (Ziziphus mauritiana) terhadap perubahan histopatologi pankreas tikus wistar (Rattus norvegicus) yang diinduksi aloksan. Penelitian ini merupakan penelitian eksperimental laboratorium dengan pendekatan true experimental design posttest only with control group pada kelompok perlakuan dan kontrol. Sampel terbagi menjadi 5 kelompok uji yaitu kelompok kontrol negatif, kontrol positif, perlakuan 1 (dosis 200 mg/kgBB), perlakuan 2 ( dosis 400 mg/kgBB) dan perlakuan 3 (dosis 800 mg/kgBB).

Abstract

Obesitas sentral berkaitan dengan peningkatan stres oksidatif akibat penumpukan lemak viseral, yang dapat mengganggu sistem antioksidan seperti superosida dismutase (SOD). Perbedaan jenis kelamin mungkin memengaruhi kadar SOD, namun data pada pegawai usia produktif dengan obesitas sentral, khususnya di lingkungan kerja seperti universitas, masih terbatas. Penelitian ini bertujuan untuk mengetahui hubungan antara jenis kelamin dengan kadar superoksida dismutase (SOD) pada pegawai dengan obesitas sentral di Universitas Nusa Cendana. Penelitian observasional analitik dengan desain potong lintang ini melibatkan 30 pegawai dengan obesitas sentral yang dipilih menggunakan teknik purposive sampling. Jenis kelamin diperoleh melalui kuesioner, obesitas sentral diukur berdasarkan lingkar pinggang, dan kadar SOD diukur dari sampel darah menggunakan metode laboratorium terstandar. Analisis data menggunakan uji Shapiro-Wilk untuk normalitas dan uji Mann-Whitney U untuk signifikansi (p < 0,05). Median kadar SOD pada laki-laki sebesar 12,91 U/mL dan perempuan 11,43 U/mL, tanpa perbedaan signifikan (p = 0,633). Jenis kelamin tidak berhubungan dengan kadar SOD pada pegawai dengan obesitas sentral di Universitas Nusa Cendana; kadar SOD dipengaruhi oleh obesitas sentral dan faktor gaya hidup.

Abstract

Propionibacterium acnes is a type of bacteria that typically exists on skin areas with many sebaceous glands, like the scalp and face. The exploration of natural antibacterial agents made from herbal plants is one approach to decrease resistance issues. One such plant utilized is red betel, scientifically known as Piper crocatum. The objective of this study is to assess the antibacterial properties of the ethanol extract from red betel leaves against Propionibacterium acnes. This study adopted a true experimental framework with a post-test only control group model. The red betel leaf extract was produced through maceration using a 70% ethanol solution, followed by evaporation until a concentrated extract was achieved. In this study, the treated groups included various concentrations: 100%, 50%, 25%, 12.5%, 6.25%, 3.125%, and 1.56%, alongside a positive control using clindamycin and a negative control using sterile aquades. The antibacterial testing was performed using the disc diffusion method, referred to as the Kirby-Bauer technique against Propionibacterium acnes bacteria. The analysis conducted was the One Way Anova statistical test. Findings from this study reveal that the extract of red betel leaves contains alkaloids, tannins, saponins, flavonoids, and terpenoids. The testing outcomes indicate that the average diameter of the inhibition zone resultant from each sample is 11.16 mm for the 100% concentration, 9.63 mm for the 50% concentration, 8.85 mm for the 25% concentration, 8.21 mm for the 12.5% concentration, 7.78 mm for the 6.25% concentration, 6.93 mm for the 3.125% concentration, and 0 mm for the 1.56% concentration. From the results, it can be concluded that the ethanol extract from red betel leaves exhibits antibacterial activity against the growth of Propionibacterium acnes.
