Non-Communicable Diseases Practice Questions

Q: Which is the most common tumor leading to death in adults?

Lung cancer. ***Lung cancer*** - **Lung cancer** is the most common cause of cancer-related death in both men and women worldwide [1], [2]. - Its high mortality is attributed to its aggressive nature, late diagnosis, and limited treatment options for advanced stages [3]. *Prostate cancer* - While **prostate cancer** is very common in men, it typically has a slower progression and a relatively high survival rate compared to lung cancer. - Early detection through screening often leads to successful treatment and a good prognosis. *Colorectal cancer* - **Colorectal cancer** is a significant cause of cancer mortality but ranks behind lung cancer in overall deaths [2]. - Improved screening methods like colonoscopies allow for early detection and removal of precancerous polyps, reducing mortality. *Leukemia* - **Leukemia** refers to cancers of the blood and bone marrow, and while serious, they are less common causes of cancer death than solid tumors like lung, colorectal, or prostate cancer [2]. - Advances in chemotherapy, stem cell transplantation, and targeted therapies have significantly improved survival rates for many types of leukemia.

Q: Which condition has the maximum relative risk attributed to obesity?

DM. ***DM*** - Obesity is a major risk factor for Type 2 Diabetes Mellitus (T2DM), with a **relative risk often exceeding 3-7 times that of normal-weight individuals**, and even higher for severe obesity. - The link is primarily due to **insulin resistance** caused by increased adipose tissue. *Hypertension* - Obesity significantly increases the risk of hypertension, with a relative risk typically in the range of **2 to 3 times higher** than normal-weight individuals. - The mechanisms involve increased **blood volume**, **sympathetic nervous system activity**, and **renal sodium reabsorption**. *CHD* - Obesity is a strong independent risk factor for Coronary Heart Disease (CHD), contributing to a relative risk of approximately **1.5 to 2.5 times higher** than normal weight. - It often acts by exacerbating other risk factors like **hypertension**, **dyslipidemia**, and **diabetes**. *Cancer* - Obesity is linked to various cancers, including endometrial, esophageal adenocarcinoma, renal cell, and breast cancer in postmenopausal women, with relative risks typically ranging from **1.2 to 2 times higher** for specific cancers. - The pathways include **chronic inflammation**, altered **hormone levels** (e.g., estrogen), and **insulin-like growth factor signaling**.

Q: In the context of managing chronic diseases, which principle is referred to as the 'Rule of Halves'?

Hypertension. ***Hypertension*** - The **"Rule of Halves"** specifically describes the statistical observation that in many populations, approximately half of individuals with hypertension are aware of their condition, half of those aware are treated, and half of those treated achieve adequate blood pressure control. - This concept highlights significant challenges in the **detection**, **treatment initiation**, and **effective management** of hypertension within a population. *Weight Management* - While important for overall health, **weight management** does not have a commonly recognized "Rule of Halves" in its diagnostic or treatment cascade. - It involves complex behavioral, dietary, and physical activity interventions, rather than a specific statistical division of care. *Diabetes Management* - Similar to hypertension, **diabetes management** faces challenges in diagnosis and control, but the "Rule of Halves" is not a standard term used to describe its epidemiological cascade. - Management focuses on blood glucose control, lifestyle modifications, and preventing complications, without this specific statistical breakdown. *Visual Impairment* - The concept of the **"Rule of Halves"** is not associated with the diagnosis, awareness, or treatment of visual impairment. - Management of visual impairment involves identifying the underlying cause and providing corrective lenses, surgery, or low-vision aids.

Q: Which of the following is a non- modifiable risk factor for CHD -

Old age. Old age - Age is a **non-modifiable risk factor** for Coronary Heart Disease (CHD) because it is an inherent biological process that cannot be changed [3]. - The risk of developing CHD **increases with age** due to cumulative exposure to other risk factors and natural wear and tear on the cardiovascular system [3]. *Diabetes* - Diabetes is a **modifiable risk factor** for CHD because it can be managed and controlled through lifestyle changes, medication, and regular monitoring [2]. - **Poorly controlled diabetes** significantly increases the risk of heart disease by damaging blood vessels and promoting atherosclerosis. *Smoking* - Smoking is a highly **modifiable risk factor** for CHD as it can be completely stopped [1], [2]. - **Cessation of smoking** significantly reduces the risk of heart attack and stroke over time [1]. *Hypertension* - Hypertension is a **modifiable risk factor** for CHD because blood pressure can be lowered through lifestyle interventions, such as diet and exercise, and pharmacotherapy [2]. - **Uncontrolled high blood pressure** places increased stress on the heart and blood vessels, accelerating the development of atherosclerosis [1].

Q: According to the World Health Organization, blindness is defined as counting fingers at a distance of what?

3 meters. ***3 meters*** - The World Health Organization (WHO) defines **blindness** for epidemiological purposes as a best-corrected visual acuity worse than **3/60** or **counting fingers at 3 meters** in the better eye. - This criterion helps in global health surveillance and resource allocation for visual impairment. *1 meter* - Counting fingers at **1 meter** represents a visual acuity of approximately **1/60**, which is **worse than 3/60** and therefore also falls into the **blindness** category. - However, the WHO definition specifically uses **3 meters (3/60)** as the threshold—visual acuity worse than this (including 1/60) confirms blindness, but 3/60 is the defining cut-off point. *6 meters* - Counting fingers at **6 meters** would imply a visual acuity of approximately **6/60**, which is better than the WHO threshold for blindness. - This level of vision falls into the category of **severe visual impairment**, not blindness. *9 meters* - Counting fingers at **9 meters** suggests a relatively better level of visual acuity. - This is significantly above the WHO definition of blindness and would be classified as **moderate visual impairment** or better.

Q: Commonest carcinoma in men in tropical countries is

Ca oral cavity. ***Ca oral cavity*** - The high prevalence of **tobacco chewing** and **betel nut use** in many tropical countries significantly contributes to the high incidence of oral cavity cancer in men. - This habit is deeply ingrained in the **cultural practices** of these regions, leading to chronic irritation and carcinogenesis. *Ca rectum* - While colorectal cancer is common globally, it is generally **less prevalent** in tropical regions compared to oral cavity cancers attributed to specific lifestyle factors. - Its incidence is often linked to **Westernized diets** and sedentary lifestyles, which are not universally dominant in all tropical areas. *Ca testis* - Testicular cancer is more common in **younger men** in developed countries and is not typically the leading cancer in men across tropical regions. - It accounts for a **smaller proportion** of all male cancers globally compared to more prevalent cancers like oral cavity, lung, or prostate cancer. *Ca bladder* - Bladder cancer is often associated with **smoking** and occupational exposure to certain chemicals (e.g., dyes, rubber). - While present, it does not typically surpass the incidence of **oral cavity cancer** in tropical regions, where unique risk factors are highly prevalent.

Q: World Heart Day is celebrated on?

29th September. ***29th September*** - **World Heart Day** is an annual event observed globally on this date to raise awareness about **cardiovascular diseases (CVDs)** including heart disease and stroke - Established by the **World Heart Federation** to promote heart health and encourage preventive measures through lifestyle modification - The day aims to reduce the global burden of CVD through education about risk factors and healthy living *28th September* - This date is not recognized as World Heart Day - Often confused due to proximity to the actual date (29th September) *8th September* - **World Physiotherapy Day** is celebrated on this date, focusing on the role of physical therapy in health and well-being - While physical activity is crucial for cardiovascular health, this is a distinct observance from World Heart Day *1st December* - **World AIDS Day** is observed on this date to raise awareness about the AIDS pandemic and HIV infection - This date is unrelated to cardiovascular health awareness

Q: Goal of Prudent diet: Total Cholesterol to HDL ratio should be less than:

3.5. ***3.5*** - A total cholesterol to HDL ratio of less than **3.5** is generally considered optimal for reducing the risk of **atherosclerotic cardiovascular disease (ASCVD)**. - This ratio reflects a favorable balance with higher levels of **high-density lipoprotein (HDL)**, often referred to as "good cholesterol". *1.5* - While a ratio of 1.5 would indicate excellent lipid health, it is an **unrealistically low** and rarely achievable target for most individuals through lifestyle changes alone. - This value is significantly below typical healthy ranges and is not a standard goal for a **prudent diet**. *4.5* - A ratio of **4.5** or higher indicates an **increased risk** of cardiovascular disease, suggesting a less favorable lipid profile. - This value is generally considered **suboptimal** and would be a target for intervention rather than a goal of a prudent diet. *2.5* - A ratio of 2.5 would be considered a **very good** and healthy lipid profile, indicating a low risk of cardiovascular disease. - Although beneficial, the standard guideline for a healthy target is typically less than **3.5**, making 2.5 a more aggressive but still positive target.
