The association between lifestyle and hypertension among elderly: A cross-sectional study at the Merdeka Community Health Center, Karo Regency
No full textBackground: Hypertension is a non-communicable disease with a continually rising prevalence, particularly within the elderly population. Lifestyle factors play a critical role in influencing the risk of developing hypertension. This study aimed to determine the relationship between lifestyle and the incidence of hypertension among the elderly at Merdeka Health Center in 2025.
Methods: This study employed a quantitative design with a descriptive correlational method and a cross-sectional approach. The study population consisted of all 125 elderly individuals who visited the Merdeka Health Center between January and December 2024. A sample of 55 respondents was selected using an accidental sampling technique. Data were collected through questionnaires and blood pressure measurements and were subsequently analyzed using the Spearman's rho correlation test with a significance level of α=0.05.
Results: The findings indicated a significant relationship between physical activity (p=0.046;r=−0.270), dietary patterns (p=0.029;r=0.295), rest/sleep habits (p=0.007;r=0.361), pesticide exposure (p=0.009;r=−0.351), and family history of hypertension (p=0.000;r=0.512) with the incidence of hypertension in the elderly. However, no significant relationship was found between smoking history and the incidence of hypertension (p=0.057;r=−0.258).
Conclusion: Most of the investigated lifestyle components—specifically physical activity, dietary patterns, and rest habits—along with pesticide exposure and family history, have a significant association with the incidence of hypertension in the elderly. It is therefore recommended that elderly individuals adopt a healthy lifestyle for the prevention and control of hypertension
Relationship between clean water quality and sanitation with health problems in Rambung Baru Village, Sibolangit Sub-district
No full textThe global challenge of inadequate access to clean water and sanitation continues to impose a substantial burden on public health, especially in developing regions. This study investigates the relationship between water quality, sanitation conditions, and health disorders among residents of Rambung Baru Village, Sibolangit Subdistrict, Indonesia. Employing a cross-sectional analytical design, data were collected from 130 households utilizing spring water as their primary source. Water quality was evaluated through physical, chemical, and microbiological analyses, while sanitation hygiene and health disorder data were gathered via questionnaires and health center records. The results indicate that over half of the respondents consumed water failing to meet quality standards, and nearly half experienced inadequate sanitation hygiene around water sources. A statistically significant association was found between poor water quality and the incidence of health disorders (p = 0.007), with affected individuals showing higher prevalence of diarrhea, acute respiratory infections, and skin diseases. Conversely, no significant relationship emerged between sanitation hygiene and health disorders (p = 0.289), although trends suggest a potential influence. These findings underscore the critical role of water quality in disease transmission and point to the need for prioritized interventions targeting water source protection and household water treatment. Given the complex interactions among water quality, sanitation, and hygiene behaviors, integrated approaches combining infrastructure improvements with community education on hygiene practices are essential. Further longitudinal research incorporating confounding factors is recommended to deepen understanding and guide effective public health strategies in similar rural contexts
Effect of hygiene of kitchen utensils and food handlers on microbial counts in Jumbo Ayahanda Iced Tea drinks, Medan City
No full textFood safety is a crucial aspect of public health, aiming to prevent diseases resulting from the consumption of contaminated food or beverages. This study employed a quantitative research design with an analytical observational approach. The analytical observational method was used to determine the relationship between two independent variables—kitchen utensils and food handler hygiene—and the dependent variable, the microbial count in jumbo iced tea beverages sold along Ayahanda Street, Medan. The quantitative approach was chosen for its ability to measure data numerically and statistically analyze the relationships among variables. Data collection was conducted through direct observation using standardized assessment sheets. The kitchen utensil variable included evaluation of the cleanliness of plastic cups, straws, cool boxes, and cup sealer machines; washing procedures; equipment storage; cleaning methods for stainless steel, glass, and food-grade plastic tools; as well as cleaning frequency. The food handler hygiene variable was assessed based on hand hygiene before and after beverage preparation, nail cleanliness, cleanliness of clothing and aprons during work, and the use of personal protective equipment such as masks and gloves. Microbiological testing involved determining the Total Plate Count (TPC) and comparing the results with established safety standards. Observational and laboratory data were processed and analyzed statistically using the Chi-Square test with a 5% significance level (α = 0.05) to evaluate the effect of kitchen utensil conditions and food handler hygiene on microbial counts. The results showed that the majority of jumbo iced tea samples contained microbial levels within safe limits. Of the 30 samples tested, only 4 samples (13.3%) contained detectable microbes, while 26 samples (86.7%) showed no microbial growth based on the Total Plate Count method. There was no significant association between kitchen utensil cleanliness and microbial counts in jumbo iced tea sold on Ayahanda Street, Medan (p-value = 0.507). However, a significant relationship was found between food handler hygiene and microbial counts in the same products (p-value = 0.024)
The association between working posture and work duration with symptoms of Carpal Tunnel Syndrome (CTS) among online motorcycle taxi drivers in Medan City
No full textCarpal Tunnel Syndrome (CTS) is a neurological disorder caused by compression of the median nerve, commonly observed among workers performing repetitive movements. Online motorcycle taxi drivers represent a high-risk group due to demands for extended working hours and non-ergonomic riding postures. This study aimed to analyse the association between working posture, working duration, and complaints of CTS among online motorcycle taxi drivers. This observational analytical study employed a cross-sectional design and involved 92 online motorcycle taxi drivers in the Universitas Prima Indonesia area, Medan, selected via consecutive sampling. Data were collected using a characteristics questionnaire, the Boston Carpal Tunnel Questionnaire (BCTQ), Phalen's Test, and posture observation using the Rapid Upper Limb Assessment (RULA). Data were analysed using the Chi-Square test. Results indicated that 57.6% of respondents reported CTS complaints. The majority of respondents worked longer than 8 hours per day (66.3%) and had low-risk working postures (48.9%); however, the proportion of CTS was highest among those with high-risk postures (72.4%). Statistical analysis revealed a significant association between working posture and CTS occurrence (p=0.041) and between working duration and CTS occurrence (p=0.009). Working longer than 8 hours per day conferred a 3.2-fold increased risk of developing CTS. It is concluded that poor working posture and prolonged working duration are significantly associated with a higher incidence of CTS among online motorcycle taxi drivers. Ergonomic interventions, regulation of working hours, and occupational health education are recommended for prevention
