Para-Clinical Community Medicine flashcards — 51 questions with answers
Define Community Medicine.
The branch of medicine that deals with the health of populations (rather than individuals), focusing on the promotion of health, prevention of disease, and the organization of health services for a defined community.
What is the difference between 'health' as defined by the WHO (1948) and the medical model of health?
WHO defines health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity" (positive, holistic). The medical model defines health negatively as the mere absence of disease.
What is the scope of Community Medicine (its three core functions)?
Health promotion, disease prevention (primary, secondary, tertiary), and the organization/administration of health services for the community, guided by epidemiology and biostatistics.
Name the four levels of prevention in Community Medicine.
Primordial prevention (prevent emergence of risk factors), primary prevention (prevent disease onset), secondary prevention (early detection and treatment), and tertiary prevention (limit disability and rehabilitate).
In the history of Community Medicine, who is regarded as the 'Father of Epidemiology' and for what work?
John Snow, for his 1854 investigation of the Broad Street cholera outbreak in London, demonstrating that cholera was spread by contaminated water (before the germ theory).
Who is considered the 'Father of Medicine' and what concept did he introduce regarding disease and environment?
Hippocrates; in 'On Airs, Waters, and Places' he proposed that disease is influenced by environmental factors (climate, water, air) rather than solely supernatural causes.
What was Edwin Chadwick's major contribution to public health?
His 1842 'Report on the Sanitary Condition of the Labouring Population of Great Britain' linked poverty and poor sanitation to disease, driving the Public Health Act of 1848 (sanitary reform movement).
What are the four levels of a typical national health system pyramid?
Primary level (community/PHC), secondary level (district hospitals, specialist referral), tertiary level (teaching/specialized hospitals), and the central/national level (policy and administration).
What are the WHO's six building blocks of a health system?
(1) Service delivery, (2) Health workforce, (3) Health information systems, (4) Access to essential medicines, (5) Financing, and (6) Leadership/governance.
What are the essential components of Primary Health Care as defined by the Alma-Ata Declaration (1978)?
Represented by the mnemonic ELEMENTS: Education, Local disease control, Expanded immunization, Maternal & child health/family planning, Essential drugs, Nutrition, Treatment of common diseases, and Safe water/sanitation.
State the epidemiological triad (agent-host-environment model).
Disease results from the interaction of three factors: the agent (causative organism/factor), the host (susceptible individual), and the environment (external factors favoring transmission).
Define incidence rate and give its formula.
The number of new cases of a disease occurring in a defined population during a specified period. $$\text{Incidence rate} = \frac{\text{No. of new cases during a period}}{\text{Population at risk}} \times 1000$$
Define prevalence and give the point prevalence formula.
The total number of existing cases (old + new) in a population at a given time. $$\text{Point prevalence} = \frac{\text{No. of existing cases at a point in time}}{\text{Total population at that time}} \times 1000$$
What is the relationship between incidence (I), prevalence (P), and duration of disease (D)?
For a stable (steady-state) condition, prevalence equals incidence times average duration: $$P = I \times D$$
Define Community Medicine's concept of '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.
Name the three main types of descriptive epidemiological studies.
Case reports/case series, cross-sectional (prevalence) studies, and ecological (correlational) studies. They describe disease by time, place, and person.
What three characteristics does descriptive epidemiology use to characterize disease occurrence?
Time (trends, seasonal/epidemic/secular patterns), Place (geographic distribution), and Person (age, sex, occupation, and other attributes).
Compare a cohort study and a case-control study by their direction of inquiry.
A cohort study is prospective/forward-looking: starts with exposure and follows to outcome. A case-control study is retrospective/backward-looking: starts with the outcome (disease) and looks back at exposure.
Which measure of association is calculated in a cohort study, and what is its formula?
Relative Risk (Risk Ratio). $$RR = \frac{\text{Incidence in exposed}}{\text{Incidence in non-exposed}} = \frac{a/(a+b)}{c/(c+d)}$$
Which measure of association is calculated in a case-control study, and what is its formula?
Odds Ratio. $$OR = \frac{ad}{bc}$$ where a, b, c, d are the cells of the 2×2 exposure-disease table.
Show the other 31 Community Medicine flashcards
How do you interpret a Relative Risk value of 1, greater than 1, and less than 1?
$RR = 1$: no association between exposure and disease. $RR > 1$: exposure increases risk (positive association). $RR < 1$: exposure is protective.
Define attributable risk (AR) and give its formula.
The excess risk of disease in the exposed group attributable to the exposure. $$AR = I_{exposed} - I_{non-exposed}$$
What is the gold-standard design in experimental epidemiology?
The Randomized Controlled Trial (RCT), in which participants are randomly allocated to intervention or control groups to test the efficacy of an intervention.
What is the purpose of randomization and blinding in an RCT?
Randomization eliminates selection bias and evenly distributes confounders between groups; blinding (single/double/triple) reduces observer and information bias.
Define sensitivity and specificity of a screening test with formulas.
Sensitivity = ability to correctly identify diseased individuals: $\frac{TP}{TP+FN}$. Specificity = ability to correctly identify non-diseased: $\frac{TN}{TN+FP}$.
Define biostatistics.
The application of statistical methods to the collection, organization, analysis, and interpretation of data related to biology, medicine, and public health.
Distinguish qualitative from quantitative data, with subtypes.
Qualitative (categorical) data: nominal (unordered categories, e.g. blood group) and ordinal (ordered, e.g. disease severity). Quantitative (numerical) data: discrete (counts) and continuous (measured, e.g. weight).
Distinguish a population parameter from a sample statistic.
A parameter is a numerical characteristic of the whole population (e.g. population mean $\mu$); a statistic is the corresponding value calculated from a sample (e.g. sample mean $\bar{x}$) used to estimate the parameter.
Give the formula for the arithmetic mean of a sample.
$$\bar{x} = \frac{\sum_{i=1}^{n} x_i}{n}$$ where $x_i$ are the observations and $n$ is the sample size.
Define the median and mode.
The median is the middle value when data are arranged in order (the value dividing the distribution into two equal halves). The mode is the most frequently occurring value.
Give the formula for the sample standard deviation.
$$s = \sqrt{\frac{\sum_{i=1}^{n}(x_i - \bar{x})^{2}}{n-1}}$$
Define the coefficient of variation and give its formula.
A relative, unitless measure of dispersion used to compare variability between datasets with different units/means. $$CV = \frac{s}{\bar{x}} \times 100\%$$
In a normal (Gaussian) distribution, what percentage of observations fall within 1, 2, and 3 standard deviations of the mean?
Approximately 68.3% within $\mu \pm 1\sigma$, 95.4% within $\mu \pm 2\sigma$, and 99.7% within $\mu \pm 3\sigma$ (the empirical/68-95-99.7 rule).
For a right (positively) skewed distribution, what is the order of mean, median, and mode?
$\text{Mode} < \text{Median} < \text{Mean}$ (the mean is pulled toward the long right tail).
Give the formula for the standard error of the mean (SEM).
$$SEM = \frac{s}{\sqrt{n}}$$ where $s$ is the sample standard deviation and $n$ is the sample size.
State the null hypothesis and alternative hypothesis concepts in significance testing.
The null hypothesis ($H_0$) states there is no difference/association. The alternative hypothesis ($H_1$) states a difference/association exists. Testing decides whether to reject $H_0$.
Define Type I and Type II errors in hypothesis testing.
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 = $1-\beta$.
What does a p-value represent, and what is the conventional threshold for significance?
The probability of obtaining the observed result (or more extreme) if the null hypothesis were true. Conventionally, $p < 0.05$ is considered statistically significant.
Which statistical test compares means of two independent groups, and which compares proportions/categorical data?
Student's t-test compares means of two groups (ANOVA for more than two). The chi-square ($\chi^{2}$) test compares categorical data/proportions.
Give the formula for the chi-square test statistic.
$$\chi^{2} = \sum \frac{(O - E)^{2}}{E}$$ where $O$ = observed frequency and $E$ = expected frequency.
What does the Pearson correlation coefficient (r) measure, and what is its range?
The strength and direction of a linear relationship between two continuous variables. It ranges from $-1$ to $+1$; $r=0$ means no linear correlation, $\pm 1$ means perfect linear correlation.
Write the equation of a simple linear regression line and define its terms.
$$y = a + bx$$ where $y$ is the dependent variable, $x$ the independent variable, $a$ the intercept, and $b$ the regression coefficient (slope, the change in $y$ per unit change in $x$).
What does the coefficient of determination ($r^{2}$) indicate?
The proportion of the total variation in the dependent variable that is explained by the independent variable in the regression model (e.g. $r^{2}=0.64$ means 64% of variance is explained).
Define environmental health.
The branch of public health concerned with all aspects of the natural and built environment that may affect human health, aiming to prevent disease and create health-supportive environments.
What are the WHO water quality standards for residual chlorine and the acceptable turbidity of drinking water?
Free residual chlorine should be at least $0.5\ \text{mg/L}$ after 1 hour of contact; turbidity of drinking water should be less than $5\ \text{NTU}$ (ideally $<1\ \text{NTU}$).
List the main steps in conventional water purification at a treatment plant.
Storage (sedimentation), coagulation/flocculation, sedimentation, filtration (slow sand or rapid sand), and disinfection (usually chlorination).
What is the principle of chlorination and the term for the chlorine needed to satisfy demand before free residual chlorine appears?
Chlorine oxidizes and kills pathogens via hypochlorous acid. The amount consumed by organic matter/microbes before free chlorine remains is the 'chlorine demand'; the 'break-point' is where demand is met and free residual chlorine begins to rise.
Name the two major categories of air pollutants with examples.
Primary pollutants (emitted directly: CO, $\ce{SO2}$, $\ce{NO_x}$, particulate matter) and secondary pollutants (formed in the atmosphere: ozone $\ce{O3}$, PAN, photochemical smog).
What are the recognized methods of solid waste disposal in a community?
Sanitary landfill, composting, incineration, and recycling; for special/biomedical waste, autoclaving and controlled incineration are used (following segregation by color-coded bins).
State the three main functions of food/nutrients and classify macronutrients vs micronutrients.
Functions: energy (fuel), body-building (growth/repair), and protective/regulatory. Macronutrients (needed in large amounts): carbohydrates, proteins, fats. Micronutrients (small amounts): vitamins and minerals.
How is Body Mass Index (BMI) calculated and what are the WHO cut-offs for underweight, normal, overweight, and obese?
$$BMI = \frac{\text{weight (kg)}}{[\text{height (m)}]^{2}}$$ Underweight $<18.5$; normal $18.5\text{--}24.9$; overweight $25\text{--}29.9$; obese $\geq 30\ \text{kg/m}^{2}$.
