Abstract

Background: The results of a study by the Centers for Disease Control and Prevention (CDC) in 2014 showed that 35.2% of adults (≥18 years) in the United States had short sleep duration. Medical students are relatively prone to having poor sleep quality. Sleep quality is one of the factors that affect concentration, where poor sleep quality can have an impact on decreased ability to concentrate, memory, ability to solve problems and make decisions and think critically. Objective: To determine the relationship between sleep quality and concentration in students of the Faculty of Medicine, University of Nusa Cendana. Methods: This research is an observational analytic study with cross sectional design conducted on preclinical students of the Faculty of Medicine, University of Nusa Cendana. The sampling technique was stratified random sampling with a sample size of 69 people. Sleep quality data were obtained from filling out the PSQI questionnaire and testing the concentration using the Stroop test. Data analysis used the Contingency coefficient correlation test. Results: The sample with poor sleep quality was 40 people (58%) and 29 people (42%) had good sleep quality. The number of samples with a good concentration was 35 people (50.7%) and a bad concentration was 34 people (49.3%). The results of bivariate analysis using the Contingency coefficient test obtained p value = 0.036 (p <0.05) and r=0,244. Conclusion: There is a significant and weak relationship between sleep quality and concentration among students at the Faculty of Medicine, University of Nusa Cendana. Key words: sleep quality, concentration, medical students.

Abstract

Malaria remains a major public health challenge in eastern Indonesian and anaemia is a principal haematological complication with notable clinical and functional consequences. Community-based data quantifying malaria-associated anaemia in East Sumba are scarce. This study aimed to determine the prevalence of anaemia associated with malaria and to evaluate the association between malaria infection and anaemia among residents of Mau Bokul Village, East Sumba. An analytical cross-sectional survey was conducted on 98 community participants recruited by consecutive sampling during June–July 2025. Malaria diagnosis was established by microscopy of Giemsa 3%-stained thick blood films and haemoglobin (Hb) was quantified using a point-of-care digital meter (Easy Touch GCHb). Fisher's Exact Test analyzed the association between malaria and anaemia with significance set at (p < 0.05).  The results are indicate malaria prevalence was 8.2% (8/98), and anaemia prevalence was 34.7% (34/98). All malaria-positive individuals were anaemic. The association between malaria and anaemia was statistically significant (p < 0.001).

Abstract

The prevalence of diabetes mellitus continues to increase, alongside a growing burden of central obesity as a major contributing risk factor. The waist-to-hip ratio (WHR) serves as a practical anthropometric indicator for assessing central obesity, whereas glycated hemoglobin (HbA1c) reflects long-term glycemic control. Nevertheless, the evidence regarding the association between WHR and HbA1c levels remains inconclusive and varies across studies. Research objective to analyze the relationship between waist-to-hip ratio (WHR) and HbA1c levels among patients with diabetes mellitus at primary health care centers in Kupang City. This study employed a cross-sectional design. Venous blood samples were collected to measure HbA1c levels, while waist and hip circumferences were measured to obtain the waist-to-hip ratio (WHR) values. Data were analyzed using the Chi Square test. Result: The respondents were aged 18–59 years. The Chi-Square analysis indicated a non-significant association, with a p-value of 0.067. There was no significant association between waist-to-hip ratio (WHR) and HbA1c levels among patients with diabetes mellitus at community health centers in Kupang City. Glycemic control is influenced not only by anthropometric parameters but also by various other factors, including dietary patterns, sex, physical activity, and lifestyle behaviors.

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.
