MBBS Social and Preventive Medicine flashcards — 55 questions with answers
Define Social and Preventive Medicine (SPM).
SPM is the branch of medicine dealing with the prevention of disease, promotion of health, and prolongation of life through organized community efforts. It combines social medicine (health in relation to social factors) with preventive medicine (preventing disease before it occurs).
What is the scope of Social and Preventive Medicine?
It spans the full spectrum of health: health promotion, specific protection, early diagnosis and treatment, disability limitation, and rehabilitation. It covers epidemiology, biostatistics, demography, environmental health, occupational health, nutrition, MCH, communicable and non-communicable disease control, and health management.
State the WHO (1948) definition of health.
"Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." Spiritual and other dimensions were later added in discussions.
What are the four levels of prevention?
1) Primordial prevention (prevent emergence of risk factors), 2) Primary prevention (health promotion and specific protection), 3) Secondary prevention (early diagnosis and prompt treatment), and 4) Tertiary prevention (disability limitation and rehabilitation).
Differentiate health promotion from specific protection.
Health promotion is non-specific action to enhance overall health (e.g., good nutrition, health education, lifestyle). Specific protection targets a particular disease/agent (e.g., immunization, fluoridation, use of specific nutrients, chemoprophylaxis).
Name a key milestone marking the start of modern public health and its figure.
John Snow's 1854 investigation of the Broad Street cholera outbreak in London (removing the pump handle) is a landmark; he is regarded as the father of modern epidemiology. The 1848 Public Health Act in England also marked the start of state-organized public health.
What were the three historical phases (eras) in the evolution of public health?
1) Disease control phase (sanitary/environmental, 1880s), 2) Health promotive phase (personal/MCH services), and 3) Social engineering / new public health phase (chronic disease, risk factors, comprehensive care).
Define Primary Health Care (PHC) as per the Alma-Ata Declaration.
Essential health care based on practical, scientifically sound, socially acceptable methods and technology, made universally accessible to individuals and families at a cost the community and country can afford, in the spirit of self-reliance and self-determination. Declared at Alma-Ata, 1978, with the goal "Health for All by 2000."
What are the four principles (pillars) of Primary Health Care?
1) Equitable distribution (accessibility), 2) Community participation, 3) Intersectoral coordination, and 4) Appropriate technology.
List the eight essential elements of Primary Health Care (Alma-Ata).
Remembered as ELEMENTS: 1) Education about health, 2) Locally endemic disease control, 3) Expanded immunization, 4) Maternal and child health/family planning, 5) Essential drugs, 6) Nutrition (food supply), 7) Treatment of common diseases/injuries, 8) Safe water and sanitation. (Later mental health was added.)
Define epidemiology.
The study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems (John Last).
What is the epidemiological triad?
The interaction of Agent, Host, and Environment. Disease results when this equilibrium is disturbed; the environment acts as the medium for agent–host interaction.
Differentiate incidence from prevalence and give their formulas.
Incidence = new cases over a period. $$\text{Incidence rate} = \frac{\text{Number of new cases during a period}}{\text{Population at risk}} \times 1000$$ Prevalence = existing (old + new) cases at a point/period. $$\text{Point prevalence} = \frac{\text{Total existing cases at a point in time}}{\text{Population at that point}} \times 1000$$
State the relationship between prevalence, incidence and duration of disease.
For a stable (steady-state) condition: $$P = I \times D$$ where $P$ = prevalence, $I$ = incidence, and $D$ = average duration of the disease.
Define attack rate and give its formula.
Attack rate is an incidence rate used during epidemics, expressed as a percentage. $$\text{Attack rate} = \frac{\text{Number of new cases during outbreak}}{\text{Total population at risk}} \times 100$$
What is the basic reproduction number ($R_0$) and what does its value indicate?
$R_0$ is the average number of secondary cases produced by one infected case in a fully susceptible population. If $R_0 > 1$ the infection spreads (epidemic potential); if $R_0 < 1$ it dies out; if $R_0 = 1$ it is endemic/stable.
Classify epidemiological studies into the two broad categories.
1) Observational studies (descriptive: case report, case series, cross-sectional, ecological; analytical: case-control, cohort) and 2) Experimental/interventional studies (randomized controlled trials, field trials, community trials).
Compare cohort and case-control studies in direction and starting point.
Cohort: starts with exposure, follows forward to outcome (exposure to disease); good for rare exposures, measures incidence and relative risk. Case-control: starts with disease, looks back at exposure (disease to exposure); good for rare diseases, cheaper, measures odds ratio.
Give the formula for relative risk (RR) using a 2×2 table.
With exposed (a=disease, b=no disease) and unexposed (c=disease, d=no disease): $$RR = \frac{a/(a+b)}{c/(c+d)}$$ RR is calculated in cohort studies.
Give the formula for odds ratio (OR) and state where it is used.
$$OR = \frac{a \times d}{b \times c}$$ Used in case-control studies; it approximates relative risk when the disease is rare.

Define attributable risk (AR) and population attributable risk.
Attributable risk (risk difference) = incidence in exposed minus incidence in unexposed: $AR = I_e - I_u$. Population attributable risk = the proportion of disease incidence in the total population attributable to the exposure.
What is the gold standard study design and why?
The randomized controlled trial (RCT). Randomization balances known and unknown confounders between groups, allowing the strongest causal inference. Blinding and a control group reduce bias.
Differentiate epidemic, endemic, and pandemic.
Endemic = constant/usual presence of a disease in a population/area. Epidemic = occurrence clearly in excess of expected (outbreak). Pandemic = an epidemic spreading over several countries/continents affecting large numbers.
List the key steps in investigating a disease outbreak.
1) Verify the diagnosis, 2) Confirm the existence of an epidemic, 3) Define and identify cases (case definition), 4) Describe by time, place, person, 5) Formulate hypothesis, 6) Test hypothesis (analytical study), 7) Implement control measures, 8) Communicate findings.
What is an epidemic curve and what does its shape indicate?
A graph of number of cases against time of onset. A single sharp peak suggests a point-source (common source) outbreak; multiple/regular peaks suggest propagated (person-to-person) spread; a plateau suggests a continuous common source.
Differentiate sensitivity and specificity of a screening test.
Sensitivity = ability to correctly identify those WITH disease (true positives). Specificity = ability to correctly identify those WITHOUT disease (true negatives). High sensitivity rules disease out (SnNout); high specificity rules disease in (SpPin).
Give the formulas for sensitivity and specificity using a 2×2 table.
With TP=true positive, FN=false negative, FP=false positive, TN=true negative: $$\text{Sensitivity} = \frac{TP}{TP + FN} \qquad \text{Specificity} = \frac{TN}{TN + FP}$$
Define positive predictive value (PPV) and negative predictive value (NPV) with formulas.
PPV = probability that a person with a positive test truly has the disease; NPV = probability that a person with a negative test is truly disease-free. $$PPV = \frac{TP}{TP + FP} \qquad NPV = \frac{TN}{TN + FN}$$ Predictive values depend on disease prevalence.
How does disease prevalence affect predictive values of a test?
As prevalence increases, PPV increases and NPV decreases. Sensitivity and specificity are intrinsic to the test and do not change with prevalence, but predictive values do.
What is the criterion for selecting a disease suitable for screening (Wilson–Jungner criteria, key points)?
The disease should be an important health problem with a recognizable latent/early stage, a known natural history, an acceptable and safe test, available effective treatment, agreed policy on whom to treat, and the cost should be balanced against benefit. Screening should be a continuous process.
Differentiate qualitative and quantitative data, with sub-types.
Qualitative (categorical): nominal (no order, e.g., blood group) and ordinal (ordered, e.g., disease severity). Quantitative (numerical): discrete (counts, e.g., number of children) and continuous (measurable, e.g., height, weight).
Define the three measures of central tendency.
Mean = arithmetic average $\bar{x} = \frac{\sum x}{n}$; Median = the middle value when data are arranged in order; Mode = the most frequently occurring value.
Give the formula for the sample standard deviation.
$$s = \sqrt{\frac{\sum (x_i - \bar{x})^2}{n - 1}}$$ It measures the dispersion/spread of data around the mean; its square is the variance.
Define the coefficient of variation (CV) and its use.
$$CV = \frac{s}{\bar{x}} \times 100$$ It is a unitless relative measure of dispersion used to compare variability between data sets with different units or widely different means.
Describe the properties of a normal (Gaussian) distribution.
Bell-shaped and symmetrical about the mean; mean = median = mode. About 68% of observations lie within $\bar{x} \pm 1s$, 95% within $\bar{x} \pm 1.96s$, and 99.7% within $\bar{x} \pm 3s$.
Define probability and state its range.
Probability is the likelihood of occurrence of an event. $$P(E) = \frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$$ Its value ranges from 0 (impossible) to 1 (certain); $0 \leq P(E) \leq 1$.
List the main types of probability (random) sampling.
1) Simple random sampling, 2) Systematic sampling, 3) Stratified random sampling, 4) Cluster sampling, and 5) Multistage sampling. All give every unit a known, non-zero chance of selection.
Differentiate probability and non-probability sampling.
Probability sampling: every unit has a known non-zero chance of selection; allows generalization and estimation of sampling error (e.g., simple random, stratified). Non-probability sampling: selection is subjective with unknown probability (e.g., convenience, quota, purposive, snowball); prone to bias.
What is the standard error of the mean (SEM) and its formula?
SEM estimates how much the sample mean varies from the true population mean. $$SEM = \frac{s}{\sqrt{n}}$$ It decreases as sample size increases.
Define null hypothesis ($H_0$) and alternative hypothesis ($H_1$).
$H_0$ states there is no difference/no association between groups (the assumption to be tested). $H_1$ states there is a real difference/association. Statistical testing aims to reject or fail to reject $H_0$.
Differentiate Type I and Type II errors.
Type I error ($\alpha$) = rejecting a true null hypothesis (false positive). Type II error ($\beta$) = failing to reject a false null hypothesis (false negative). Power of a test = $1 - \beta$.
What is a p-value and the conventional level of significance?
The p-value is the probability of obtaining the observed result (or more extreme) if the null hypothesis is true. By convention, $p < 0.05$ is considered statistically significant, leading to rejection of $H_0$.
Match common statistical tests to their use: t-test, chi-square, ANOVA, correlation.
Student's t-test: compares means of two groups (quantitative). Chi-square ($\chi^2$): tests association between two categorical variables. ANOVA: compares means of three or more groups. Correlation (Pearson's $r$): measures strength/direction of linear association between two quantitative variables.
Name common software used for epidemiological data analysis.
Epi Info (CDC/WHO, free, for outbreak analysis), SPSS, STATA, SAS, R, and Microsoft Excel. Epi Info is widely used for field epidemiology and outbreak investigations.
Define disease surveillance and name its two main types.
Surveillance is the continuous, systematic collection, analysis and interpretation of health data, with timely dissemination for public health action. Types: 1) Active surveillance (health workers actively seek cases) and 2) Passive surveillance (routine reporting by facilities).
What is sentinel surveillance?
A type of surveillance where selected reporting sites (sentinel sites/health facilities) provide high-quality data on specific conditions to monitor trends, used when comprehensive reporting is not feasible (e.g., influenza, HIV sentinel sites).
List components of a Health Information System (HIS).
Data sources include census, vital statistics (births/deaths registration), notification of diseases, hospital/health facility records, epidemiological surveillance, disease registers, environmental health data, and health surveys. HIS supports planning, monitoring and evaluation.
What is the difference between Crude Death Rate and Infant Mortality Rate (with formulas)?
$$\text{CDR} = \frac{\text{Total deaths in a year}}{\text{Mid-year population}} \times 1000$$ $$\text{IMR} = \frac{\text{Deaths under 1 year in a year}}{\text{Live births in same year}} \times 1000$$ IMR is a sensitive indicator of a community's overall health and socioeconomic status.
Define DALY and its two components.
DALY (Disability-Adjusted Life Year) is a composite measure of disease burden: one DALY = one lost year of healthy life. $$\text{DALY} = YLL + YLD$$ where YLL = Years of Life Lost due to premature death and YLD = Years Lost due to Disability.
Name the main constructs of the Health Belief Model.
Perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy. It explains health behavior based on a person's beliefs about a disease and the value of action to reduce its threat.
List the stages of the Transtheoretical (Stages of Change) Model.
1) Precontemplation, 2) Contemplation, 3) Preparation, 4) Action, 5) Maintenance (and sometimes Termination/Relapse). It describes the process by which people change health behaviors over time.
State the five action areas of health promotion in the Ottawa Charter (1986).
1) Build healthy public policy, 2) Create supportive environments, 3) Strengthen community action, 4) Develop personal skills, and 5) Reorient health services toward prevention and promotion.
Differentiate health education from health promotion.
Health education is the process of providing information and skills to influence knowledge, attitudes and behavior for health (one component). Health promotion is broader, combining educational, environmental, political and organizational supports for actions conducive to health.
Compare individual, group, and mass approaches in health education methods.
Individual approach: personal contact/counselling (most effective, two-way, but limited reach). Group approach: lectures, demonstrations, group discussions, role play (moderate reach, allows interaction). Mass approach: TV, radio, posters, newspapers (widest reach but least personal, one-way).
Define community participation and empowerment in public health.
Community participation is the active involvement of the community in planning, implementing, and evaluating health programs (a PHC principle). Empowerment is the process by which communities gain control over decisions and resources affecting their health, enhancing self-reliance and ownership.
