Exercise 1a: Saudi Hospital Investigated Possible Ways

Exercise 1a Saudi Hospital Investigated The Possible Ways Of Defining

Exercise 1 A Saudi hospital investigated the possible ways of defining Hypertension in a local population. The collected data are the following: Females n1= 739, Males n2= 1257. Sample proportion of females with hypertension = 16%, and sample proportion of males with hypertension = 22%.

a) What is the proportion of females with hypertension?

b) What is the proportion of males with hypertension?

c) What is the proportion of patients suffering from hypertension?

In addition, a separate exercise involves a biostatistics class where students rated their fear of exams on a scale from 0 to 10. The data for the fear levels are categorized with corresponding frequencies, and calculations for mean, median, mode, range, sample variance, and sample standard deviation are to be performed based on this data.

Hypertension is a prevalent cardiovascular condition characterized by elevated blood pressure levels, and accurately defining its prevalence within specific populations is crucial for implementing effective public health strategies. The investigation conducted by a Saudi hospital provides valuable insights into the distribution of hypertension among males and females in their patient population, enabling healthcare professionals to understand demographic variations and tailor interventions accordingly.

The hospital's data indicates that out of 739 female patients, a certain proportion are hypertensive, with a sample proportion of 16%. Similarly, among 1,257 male patients, 22% are identified as hypertensive. To determine the actual number of hypertensive individuals in each group, the proportions are applied to the total sample sizes. For females, the calculation is 0.16 × 739 ≈ 118 females with hypertension. For males, the calculation is 0.22 × 1257 ≈ 276 males with hypertension. These figures underscore the importance of gender-specific screening and intervention programs, as the higher proportion among males suggests potential biological, behavioral, or environmental factors influencing hypertension prevalence.

The overall proportion of patients suffering from hypertension in this population can be derived by summing the hypertensive males and females and dividing by the total sample size. The total hypertensive cases are approximately 118 + 276 ≈ 394, from a combined sample of 1996 individuals. The overall prevalence then becomes 394 / 1996 ≈ 0.197, or about 19.7%. This overall prevalence rate aids in understanding the burden of hypertension in the local population, emphasizing the need for targeted health education, screening, and management programs.

In the second scenario involving students’ fear of exams, the data collected on fear levels (ranging from 0 to 10) and their frequencies allow for descriptive statistical analysis. The mean fear score can be computed by multiplying each score by its frequency, summing these products, and dividing by the total number of students. The median involves ordering students by fear score and identifying the middle value, while the mode determines the most frequently occurring fear score. The range indicates the difference between the highest and lowest scores, providing a measure of variability. The variance and standard deviation quantify the dispersion of fear scores around the mean, offering insights into students’ anxiety levels.

Such analyses are vital in understanding the psychological impact of examinations on students, guiding educators and counselors in developing strategies to mitigate exam-related anxiety. Overall, combining epidemiological data with psychological assessments offers a comprehensive view of health and well-being within specific populations, facilitating informed decision-making for health promotion and support services.
