Non-Communicable Diseases Practice Questions

Q: Economic blindness is defined as:

Vision 6/60 to 3/60. ***Vision 6/60 to 3/60*** - **Economic blindness** refers to a level of visual impairment where an individual is unable to perform most jobs requiring good sight. - This category specifically encompasses visual acuity ranging from **6/60 to 3/60** (or 20/200 to 20/400 in feet). *Severe visual impairment with vision below 1/60* - Vision below **1/60** with significant visual field loss is typically classified as **absolute blindness** or **total blindness**. - This degree of impairment is more severe than economic blindness and often implies a complete inability to see objects. *Social blindness with vision below 3/60* - **Social blindness** is defined by a visual acuity of **3/60 or less**. - This level indicates significant visual impairment where an individual may be unable to navigate independently in an unfamiliar environment. *Complete blindness with no perception of light* - This definition describes **total blindness** or **no light perception (NLP)**. - It represents the most severe form of visual loss, where the individual cannot perceive any light.

Q: Minimum age for routine screening of osteoporosis in women according to USPSTF guidelines:

65 years. ***65 years*** - The **U.S. Preventive Services Task Force (USPSTF)** recommends routine osteoporosis screening with **bone mineral density (BMD) testing** for all women aged 65 years and older. - This recommendation is based on evidence that screening in this age group can effectively reduce the risk of **osteoporotic fractures**. *55 years* - This age is **too early** for routine osteoporosis screening in women according to current USPSTF guidelines. - Screening before age 65 is recommended only for younger women at **increased risk** of osteoporosis. *60 years* - This age is also **too early** for routine osteoporosis screening in women without additional risk factors. - The benefits of universal screening typically outweigh the harms beginning at age 65. *50 years* - This age is generally considered **too young** for routine osteoporosis screening. - Women in this age group are often still premenopausal or early postmenopausal and typically do not have a sufficiently high risk to warrant routine screening.

Q: As per Indian guidelines, what is the recommended age for a woman to begin screening for cervical cancer?

30 years. ***30 years*** - **Indian guidelines** from the **Ministry of Health & Family Welfare (MoHFW)** and the **Indian Council of Medical Research (ICMR)** recommend initiating cervical cancer screening at **age 30 years** or within 3 years of first sexual contact. - The recommended screening methods in India include **VIA (Visual Inspection with Acetic Acid)**, **HPV DNA testing**, or **Pap smear**, performed every 5 years until age 65. - This approach is tailored to the **Indian healthcare setting** and resource availability. *21 years* - This is the recommended screening age according to **US guidelines (ACOG/USPSTF)**, not Indian guidelines. - While appropriate for the US context, Indian guidelines start screening later at age 30, considering **epidemiological data**, **disease prevalence**, and **healthcare infrastructure** specific to India. *25 years* - Some **European countries** and the **UK** recommend starting screening at age 25. - This is **not the recommended age** for cervical cancer screening according to Indian national guidelines. - In India, screening typically begins at age 30 years. *18 years* - Initiating cervical cancer screening at age 18 is **not recommended** by any major international or Indian guidelines. - Screening before age 21 (in US guidelines) or 30 (in Indian guidelines) often leads to **unnecessary procedures and anxiety**, as **HPV infections** and mild dysplasias in adolescents usually resolve spontaneously.

Q: What is the leading cause of mortality among non-communicable diseases (NCDs) in India?

Cardiovascular diseases. ***Cardiovascular diseases*** - **Cardiovascular diseases (CVDs)**, including **ischemic heart disease** and **stroke**, are the leading cause of mortality among NCDs in India, accounting for approximately **27% of total deaths**. - This is due to a combination of risk factors such as **hypertension**, **diabetes**, **dyslipidemia**, **tobacco use**, and **lifestyle factors** (sedentary behavior, unhealthy diet). - CVDs represent the **single largest NCD burden** in India, surpassing all other NCD categories. *Incorrect: Diabetes* - While a significant NCD and a major risk factor for CVDs, **diabetes itself is not the leading direct cause of mortality** among NCDs in India. - Diabetes ranks as an important NCD but contributes to mortality primarily through its **cardiovascular and renal complications**. - These complications are often categorized under CVDs or chronic kidney disease in mortality statistics. *Incorrect: Chronic respiratory diseases* - **Chronic respiratory diseases (CRDs)**, such as **COPD** and **asthma**, are the **second leading cause** of NCD mortality in India but rank lower than CVDs. - Major drivers include **air pollution** (both indoor and outdoor), **smoking**, and **occupational exposures**. - CRDs account for approximately 11% of total deaths in India. *Incorrect: Cancers* - **Cancers** are a significant cause of NCD mortality, ranking **third** among NCDs in India, but are not the leading cause when compared to CVDs. - Common cancers include **oral, lung, breast, cervical**, and **gastrointestinal cancers**. - Cancer accounts for approximately 9% of total deaths in India.

Q: What is the prevalence of Rheumatic Heart Disease (RHD) in India in the 5-15 years age group based on school-based screening studies?

5-7 per 1000. ***Correct: 5-7 per 1000*** - School-based screening studies focusing on the 5-15 years age group in India reveal a prevalence of **rheumatic heart disease (RHD)** ranging from **5 to 7 per 1000** children. - This prevalence highlights the significant public health burden of RHD within this vulnerable age demographic in India. - Multiple echocardiographic screening studies across different regions of India consistently report this range as the average prevalence. *Incorrect: 1-2 per 1000* - This range is generally considered too low for the true prevalence of RHD in school-aged children in India, as documented by multiple studies. - It might represent prevalence rates in regions with very strong primary prevention programs or different demographic groups. - Underestimates the actual disease burden in the Indian context. *Incorrect: 10-12 per 1000* - While higher than the actual average, this range is typically considered an overestimate for the general prevalence of RHD in this age group from school-based screenings in India. - Such high numbers might be seen in extremely high-risk or specific endemic areas but do not represent the national average. *Incorrect: 13-15 per 1000* - This range is significantly higher than the reported average prevalence of RHD in school-based screening studies in India. - This would indicate an alarmingly widespread and uncontrolled incidence of RHD, which is not supported by current epidemiological data. - May represent historical data from decades ago or specific high-risk pockets rather than current national estimates.

Q: What is the criterion for blindness as defined in India?

Visual acuity less than 6/60. ***Visual acuity less than 6/60*** - In India, **blindness** is officially defined as a visual acuity of **less than 6/60** in the better eye with best possible correction, or a visual field constriction to 20 degrees or worse. - This definition is crucial for determining eligibility for **disability benefits** and access to vision rehabilitation services under the Persons with Disabilities Act. - This threshold represents the minimum criterion for legal blindness in India. *Visual acuity less than 3/60* - A visual acuity of less than 3/60 represents **severe blindness (Category 3)**, which is **worse than the minimum threshold** of 6/60. - This level of vision loss **does qualify as legal blindness** in India, representing a more profound degree of visual impairment. - While 6/60 is the defining threshold, 3/60 indicates even more severe vision loss. *Visual acuity less than 12/60* - Visual acuity less than 12/60 but better than 6/60 indicates **low vision** or moderate visual impairment, but it does **not** meet the criteria for legal blindness in India. - This level is categorized as low vision, where individuals may still benefit from magnifiers and other visual aids. - Such individuals retain significant functional vision for many tasks. *Visual acuity less than 18/60* - A visual acuity of less than 18/60 but better than 6/60 is considered **mild to moderate visual impairment** or low vision, but it does not qualify as legal blindness. - Individuals with this vision level typically retain considerable functional vision, although they may experience difficulties with certain tasks requiring fine detail. - This level may qualify for low vision services but not disability certification for blindness.
