Discussion 4: Elizabeth Gonzalez

Question 1

The increase in tuberculosis (TB) cases in the United States from the mid-1980s to 1992 can be attributed to several factors:

The HIV/AIDS epidemic, which compromised immune systems and made people more susceptible to TB.

The emergence of drug-resistant TB strains, which were harder to treat.

Socioeconomic factors, like an increase in homelessness and drug use, created conditions conducive to TB spread.

Inadequate public health infrastructure that struggled to effectively manage and control TB.

Immigration from countries with high TB prevalence.

The situation improved post-1992 due to increased funding, better surveillance, and the introduction of directly observed therapy (DOT).

Question 2

A.  In 2007, which group had the greatest number of TB cases?

Based on the incidence rates provided, the group with the highest incidence rate of TB was males over the age of 65, with an incidence rate of 9.4 cases per 100,000 population.

B.  Does this mean that males 44-65 years of age are at greatest risk for developing TB?

Not exactly. The group with the highest risk of developing TB, according to these incidence rates, is males over the age of 65. While the incidence rate for males aged 45-64 is high (7.4 cases per 100,000), it's not the highest. It's important to note that "risk" in this context is represented by the incidence rate, not the absolute number of cases.

Thus, while males aged 45-64 have a higher risk compared to many other groups, the group with the highest risk according to this data is males over the age of 65.

Question 3

A. The incidence rates for the years 2000 to 2007 have already been calculated and are shown in the table. Incidence rate, often expressed as the number of cases per 100,000 population, is a measure of the frequency with which new cases of a disease occur in a population over a specified period. The values provided in the table represent these rates.

B. Looking at the data, the trend in TB incidence rates from 2000 to 2007 shows a steady decrease over time. Starting at a rate of 5.8 cases per 100,000 in 2000, the rate drops nearly every year, reaching 4.4 cases per 100,000 by 2007. This suggests that fewer new cases of TB were occurring each year during this period, indicating that TB control measures might have been increasingly effective.

Question 4

1. For females under 5 years old, the incidence rate is 2.3 cases per 100,000 population. This is calculated by dividing the number of cases (245) by the estimated population (10,652,174), and then multiplying the result by 100,000.

2. For males aged 5-14 years, the incidence rate is 0.7 cases per 100,000 population. This is calculated in the same way, dividing the number of cases (143) by the estimated population (20,428,571), and then multiplying the result by 100,000.

Question 5

A. According to the data provided, in 2007, the group with the highest incidence rate of TB was males over the age of 65, with an incidence rate of 9.4 cases per 100,000 population.

B. This age group might have the highest TB incidence rate for a few reasons:

· Weakened immune systems: As people age, their immune systems can weaken, making them more susceptible to infections such as TB.

· Pre-existing conditions: Older adults may have more pre-existing health conditions, which can further compromise their immune systems and increase the risk of TB.

· Exposure over time: Older adults may also have had more cumulative exposure to TB over their lifetimes, increasing the likelihood of infection.

C. The answer to question 5a is the same as the answer to question 2a. Both identified males over the age of 65 as the group with the highest incidence rate of TB in 2007. The answers are consistent because the same data was used for both questions.

Question 6

Describe the change in TB case (incidence) rates presented in Table 4 below.

1. 1950s to mid-1980s: In the years following World War II, there was a steady decline in TB cases in the U.S. This was largely due to improved living conditions, the development of effective antibiotics, and public health efforts to control the disease.

2. Mid-1980s to early 1990s: However, in the mid-1980s, there was a resurgence of TB, with an increase in cases that peaked in 1992. This increase was associated with the HIV/AIDS epidemic, the emergence of multidrug-resistant TB, increases in homelessness and drug use, and shortcomings in the public health infrastructure.

3. Mid-1990s to 2007: Following the peak in 1992, there was another decline in TB cases. This was in response to a revitalized public health effort that involved improved funding, better surveillance, the introduction of directly observed therapy (DOT), and efforts to combat HIV/AIDS.

Question 7

TB-specific death rates (also known as mortality rates) have been decreasing from 1977 to 1979:

· In 1977, the TB-specific death rate was 1.4 per 100,000 population.

· In 1978, it decreased slightly to 1.3 per 100,000 population.

· In 1979, it decreased further to 0.9 per 100,000 population.

This decline in mortality rates over these years suggests that there was an improvement in either TB treatment or prevention measures during this period.

Question 8:

To calculate the percent change in TB death rate between 1978 and 1979:

The formula for percent change is: ((New value - Old value) / Old value) * 100%

Using the data you provided, the percent change is: ((0.9 - 1.3) / 1.3) * 100% = -30.77%.

So, there was a decrease of about 30.77% in the TB death rate from 1978 to 1979.

Question 9:

The large decrease in TB death rates between 1978 and 1979 could be due to several factors, including improvements in medical treatments, successful public health interventions, and better access to healthcare services. It's also possible that changes in reporting or data collection practices might have influenced the numbers.

Question 10:

The prevalence ratio is calculated as follows:

(number of new and old TB infections during a specified time period / total population during the same time period) * 100

In this scenario:

(30 / 100) * 100 = 30

So, the prevalence ratio of TB infection in the nursing home during July is 30 per 100 residents.

Question 11:

Family assessment tools and community assessment tools serve similar purposes in identifying needs, strengths, and areas of concern, but they do so at different scales and with different focus areas.

Family assessment tools often focus on individual and family dynamics, including physical health, mental health, relationships, and living situation. Examples include genograms, which visualize family relationships and health history, and family health assessment tools, which assess physical health, lifestyle, and environmental factors.

Community assessment tools focus on a broader population. They may assess factors such as population health, socioeconomic status, access to healthcare services, and environmental conditions. Examples include community health surveys, public health data analysis, and geographic assessments of health resources.

Question 12:

Epidemiology is the science of understanding the patterns, causes, and effects of health and disease conditions in defined populations.

· Web of causation recognizes that a disease may not have a single cause, but rather a web of interconnected factors that contribute to its development. This may include genetic predisposition, environmental factors, lifestyle choices, and more.

· Morbidity is the term for illness. In epidemiology, we look at the incidence (new cases in a population over a specific time period) and prevalence (all cases, old and new, in a population at a given time) to understand the extent of disease in a population.

· Mortality refers to death. In epidemiology, we often use mortality rates to understand the lethal impact of a disease on a population.
