Health Determinants and Indicators MCQs

Disability-adjusted life years (DALY) : DALY is a measure of overall disease burden, expressed as a number of years lost due to ill-health, disability or early death. The DALY is becoming increasingly common in the field of public health and health impact assessment. The Global Burden of Disease project combines the impact of premature mortality with that of disability. It captures the population impact of important fatal and nonfatal disabling conditions through a single measure. It is calculated by formula : DALY = YLL + YLD The DALY relies on an acceptance that the most appropriate measure of the effects of the chronic illness is time. One DALY, therefore, is equal to one year of healthy life lost.

PQLI→ ranges from 0 to 100 HDI→ ranges from 0 to 1 Reference: Park's Preventive and social medicine, 27th Edition, Chapter Concept Of Health & Disease.

Life expectancy is a positive mortality indicator Notification rate is a morbidity indicator DALY is a disability indicator Bed turn over ratio (eg: hospital discharges/ average bed) is a Health ultilisation indicator Reference: Park's Preventive and social medicine, 27th edition, Chapter Principles of Epidemiology & Epidemiology methods.

DALY (Disability adjusted life years) Measure of burden of disease in a defined population and effectiveness of interventions Expresses years lost to premature deaths and years lived with disability adjusted for its severity CALCULATED as YLL+YLD Years of life lost (YLL) and years lost due to disability (YLD) Reference: Park's Preventive and social medicine, 27th edition, Chapter Principles of Epidemiology & Epidemiology methods.

Disability rates are as follows DALY (Disability adjusted life years) HALE (Health Adjusted Life Expectancy) QALY (Quality Adjusted Life Years) Sullivan’s Index/DFLE (Disability Free Life Expectancy) Reference: Park's Preventive and social medicine, 27th edition, Chapter Principles of Epidemiology & Epidemiology methods.

The HDI is a summary composite measure of a country's average achievements in three basic aspects of human development: health, knowledge and standard of living. A component in HDI includes GNI percapita/Income which can be considered as a proxy of Human living standards. Reference: Park's Preventive and social medicine, 27th Edition, Chapter Concept Of Health & Disease.

Disability rates are as follows DALY (Disability adjusted life years) HALE (Health Adjusted Life Expectancy) QALY (Quality Adjusted Life Years) Sullivan’s Index/DFLE (Disability Free Life Expectancy) HPI is Human Poverty Index (HPI) → United Nations development indicator that assessed the level of human deprivation in various countries. It considered factors like life expectancy, education, and basic living standards to measure poverty beyond income alone. Reference: Park's Preventive and social medicine, 27th edition, Chapter Principles of Epidemiology & Epidemiology methods.

Explanation: Zinc deficiency is closely associated with sexual dysfunction. Zinc is crucial for hormone synthesis, especially testosterone, and supports normal reproductive function in males. A deficiency can result in decreased testosterone levels, erectile dysfunction, reduced libido, and impaired spermatogenesis. Explanation of other options: Copper (Option B): While important for enzymatic activity and iron metabolism, copper is not directly implicated in sexual dysfunction. Magnesium (Option C): Magnesium plays a role in over 300 biochemical reactions but is not directly linked to sexual health or dysfunction. Molybdenum (Option D): A trace element involved in enzymatic processes, but no clear evidence supports a role in sexual function. Reference: https://pmc.ncbi.nlm.nih.gov/articles/PMC9778609/
