NEET-PG 2013 - Community Medicine Practice Questions

Q: What is the BMI range that defines preobesity?

25-29.9. ***25-29.9*** - A **Body Mass Index (BMI)** between 25 and 29.9 kg/m² is classified as **overweight** [1] or **preobesity**. - This range indicates an increased risk of developing various health problems associated with higher body weight [1]. *18.5-24.9* - This BMI range is considered **normal weight**, which is generally ideal for health [1]. - Individuals within this range typically have the lowest risk of weight-related health complications [1]. *30-34.9* - A BMI in this range is classified as **obesity class I** [1]. - This category indicates a significantly increased risk of developing co-morbidities such as type 2 diabetes and cardiovascular disease [1]. *35-39.9* - This BMI range represents **obesity class II** (severe obesity) [1]. - Individuals in this category face a high risk of serious health issues and often require more aggressive intervention strategies [1].

Q: All of the following are required more during lactation as compared to pregnancy, except ?

Iron. ***Iron*** - **Iron requirements are significantly higher during pregnancy** (~27 mg/day) due to the expansion of maternal red blood cell mass, fetal development, and placental iron needs. - During lactation, iron requirement decreases to **~9-10 mg/day**, lower than in pregnancy, as **lactational amenorrhea** (absence of menstruation) reduces iron loss. - This represents the **most significant decrease** in requirement from pregnancy to lactation among the listed nutrients. *Vitamin A* - The **recommended daily allowance (RDA) for Vitamin A is higher during lactation** (~1300 μg/day) compared to pregnancy (~800 μg/day). - This increased requirement ensures **adequate transfer to breast milk** to support infant's **vision development and immune function**. *Niacin* - **Niacin requirements during lactation** (~17 mg/day) are **similar to pregnancy** (~18 mg/day). - While lactation involves increased metabolic demands, niacin requirements do not show a marked increase compared to pregnancy, unlike Vitamin A and Energy. - This option is less clearly "required more" during lactation. *Energy* - **Energy requirements are significantly higher during lactation** to fuel milk production, which is energetically demanding. - A lactating woman typically needs an **additional 500 kcal/day**, compared to ~300 kcal/day in the 2nd/3rd trimester of pregnancy.

Q: What is the iron requirement for a normal menstruating adult female?

15 mg/day. ***15 mg/day*** - The recommended daily iron intake for a normal menstruating adult female was **15 mg/day** according to guidelines at the time of this examination (NEET-2013). - This higher requirement compared to males and post-menopausal women is due to **iron loss in menstrual blood**, averaging approximately **0.5-1 mg/day** additional iron loss. - **Note:** Current guidelines recommend **18 mg/day** (US RDA) or **21 mg/day** (ICMR, India), but this question reflects the 2013 standard. *20 mg/day* - This amount is **higher than the typical recommendation** for healthy menstruating women without significant pathology. - While some women with heavier menstrual bleeding might require this, it's not the baseline requirement for normal menstruation. *30 mg/day* - This intake level is typically recommended for **pregnant women** in the second and third trimesters or individuals with **diagnosed iron deficiency anemia** requiring therapeutic supplementation. - It is significantly more than the daily requirement for a healthy menstruating female. *35 mg/day* - This is an **excessively high** daily iron intake for a healthy menstruating female. - Such high doses are usually prescribed for **severe iron deficiency anemia** or specific medical conditions under supervision. - Chronic intake at this level without medical indication could potentially lead to adverse effects.

Q: Which nut has the highest protein content among the following options?

Groundnut. ***Groundnut*** - **Groundnuts** (peanuts) contain approximately **26 grams of protein per 100 grams**, which is the highest among the given options. - While botanically classified as legumes, groundnuts are commonly grouped with nuts in nutritional contexts. - They are also rich in **healthy fats**, **fiber**, and various **B vitamins**. *Almond* - **Almonds** contain about **21 grams of protein per 100 grams**, making them the second highest in protein content among the options. - They are excellent sources of **vitamin E**, **magnesium**, and **healthy monounsaturated fats**. *Walnut* - **Walnuts** contain approximately **15 grams of protein per 100 grams**, which is lower than both groundnuts and almonds. - They are notably rich in **omega-3 fatty acids** (alpha-linolenic acid). *Coconut* - **Coconut flesh** has relatively low protein content, around **3.3 grams per 100 grams**. - It is primarily known for its high content of **medium-chain triglycerides** and **saturated fats**.

Q: Pearl's index is defined as the number of unintended pregnancies per:

Per 100 woman years. ***Per 100 woman years*** - The **Pearl Index** is a common measure of the effectiveness of contraception. - It is calculated as the number of unintended pregnancies per **100 woman-years** of exposure to a contraceptive method. *Per 10 woman years* - This metric represents too small a population and duration to provide a statistically reliable measure of contraceptive effectiveness. - Using 10 woman-years as the denominator would inappropriately inflate the Pearl Index value, making methods appear less effective than they are. *Per 1000 woman years* - While a larger denominator provides greater statistical power, the standard definition of the Pearl Index specifically uses **100 woman-years**. - Expressing it per 1000 woman-years would make the index numerically smaller, potentially leading to misinterpretation if not clearly stated. *Per 50 woman years* - This denominator is not the standard convention for calculating the **Pearl Index**. - It would result in a different numerical value for the index, making direct comparisons with commonly reported Pearl Index values challenging.

Q: Indira Gandhi Matritva Sahyog Yojana is targeted at which age group?

19 years and above. ***19 years and above*** - The **Indira Gandhi Matritva Sahyog Yojana (IGMSY)**, now known as the **Pradhan Mantri Matru Vandana Yojana (PMMVY)**, is a **conditional cash transfer scheme** for pregnant and lactating women. - Eligibility for the scheme generally applies to women aged **19 years and above** for their first live birth. *Above 65 years old* - This age group is typically associated with schemes targeting **senior citizens** or those needing geriatric care, not maternal benefits. - The **Indira Gandhi Matritva Sahyog Yojana** focuses on reproductive age and maternal health. *Above 50 years old* - Women above 50 years old are generally past their child-bearing age, making them largely irrelevant for a **maternity benefit scheme**. - This age group may be eligible for different types of social security or health schemes. *Above 30 years old* - While women above 30 years old can be pregnant and benefit from the scheme, the eligibility criteria start earlier, at **19 years and above**. - Stating "above 30 years old" would exclude a significant portion of eligible beneficiaries in their early reproductive years.

Q: What was the target reduction in child mortality rates set by the Millennium Development Goals (MDGs) between 1990 and 2015?

Two-thirds. ***Two-thirds*** - The **Millennium Development Goal 4 (MDG 4)** specifically aimed to **reduce child mortality by two-thirds** among children under five years old between 1990 and 2015. - This target focused on improving maternal and child health outcomes globally. *Half* - Reducing child mortality by half was not the specific target set by MDG 4 for the 1990-2015 period. - While improvements were sought, the ambition was a more substantial reduction. *One-fourth* - A reduction of one-fourth would have been a significantly lower target than what was ultimately set and pursued by the MDGs. - The goals were designed to be ambitious yet achievable. *One-third* - Reducing child mortality by one-third falls short of the actual target established by the MDGs. - The international community aimed for a greater impact on child survival rates.

Q: Infant mortality rate in India is per 1000 live births?

34. ***34*** - As per the **Sample Registration System (SRS)** data around **2012-2013**, India's **Infant Mortality Rate (IMR)** was reported as **34 deaths per 1,000 live births**. - This represents the number of infant deaths (before completing one year of age) per 1,000 live births in a given year. - This was the approximate national average used for the NEET-2013 examination period. *25* - This figure represents a lower IMR than the national average for India during 2012-2013. - While some progressive states like Kerala had achieved IMR closer to this figure, it was not the overall national rate at that time. *55* - This figure is higher than the reported national IMR for India in 2012-2013. - India's IMR had already declined below this level due to improved maternal and child health programs under NRHM (National Rural Health Mission). *60* - This value represents a historical estimate from earlier years (pre-2010). - By 2012-2013, India had made significant progress in reducing infant mortality from these higher historical levels through better healthcare access and immunization coverage.

Q: Which of the following is a Category A bioterrorism agent?

Anthrax. ***Anthrax*** - **Anthrax**, caused by *Bacillus anthracis*, is classified as a **Category A** bioterrorism agent due to its high mortality rate, ease of dissemination, and potential for major public health impact. - It can manifest as cutaneous, inhalational, gastrointestinal, or injectional forms, with **inhalational anthrax** being the most lethal. *Brucella* - **Brucella** species cause brucellosis, which is classified as a **Category B** bioterrorism agent. - While it can be debilitating, it generally has a lower mortality rate and less public health impact than Category A agents. *Q fever* - **Q fever**, caused by *Coxiella burnetii*, is another **Category B** bioterrorism agent. - It causes a flu-like illness and can have chronic complications but is not as severe or easily disseminated as Category A agents. *Typhus fever* - **Typhus fever**, caused by *Rickettsia prowazekii* (epidemic typhus) or *Rickettsia typhi* (murine typhus), is a **Category B** bioterrorism agent. - It can cause severe illness but is not among the highest-priority agents like anthrax, smallpox, or botulism.
