Abstract

Background: Cholesterol is essential for the formation of cell membranes, bile salts, hormones, and vitamin D, as well as serving as an energy source. Reduced physical activity in middle-aged adults can decrease organ function and increase the risk of metabolic disorders, while a diet high in saturated fat and low in fiber may elevate blood cholesterol levels. This study aimed to determine the relationship between dietary patterns and physical activity with total cholesterol levels in middle-aged adults in Petapahan Village, Deli Serdang Regency. Using a quantitative cross-sectional design with 47 respondents, data were collected through interviews, the Food Frequency Questionnaire (FFQ), a physical activity questionnaire, and cholesterol meter measurements, and analyzed using the Spearman correlation test. The results showed that 64% of respondents frequently consumed certain foods, 57% had light physical activity, and 36% had high cholesterol levels. Statistical analysis revealed a significant relationship between dietary patterns and physical activity with total cholesterol levels (p = 0.000), indicating that both factors are associated with cholesterol levels in middle-aged adults.

Abstract

Developing nations continue to face the disproportionate burden of anemia worldwide. Fatigue and impaired cognitive performance in teenagers, as well as impaired motor and behavioral development in children, are all symptoms of this disorder. There is a substantial risk of iron insufficiency in teenage females since their daily iron needs are about 11 mg. In order to sustain development and compensate for iron losses that occur naturally, including during menstruation, the body's iron needs rise throughout adolescence. Adolescent girls at SMA Swasta Nusantara Lubuk Pakam were the subjects of this research, which sought to examine the correlation between anemia rates and variables such nutritional intake and knowledge. The Spearman Correlation test was used to analyze the data in a cross-sectional research. With a p-value of 0.000 (<0.05), the statistical test findings demonstrated a strong correlation between dietary consumption and knowledge and the occurrence of anemia. With p-values for carbohydrates (1.000), protein (0.716), and fat (0.062) all higher than 0.05, there was no statistically significant correlation between macronutrient consumption and the prevalence of anemia. Because of this, researcher may infer that dietary carbs, proteins, and fats do not contribute to the prevalence of anemia, and we reject the alternative hypothesis (Ha) for this variable.
