  • Women often outlive men but in poorer health: what new Lancet study says

    Why in the news?

    Over 30 years, a study examining 20 diseases revealed minimal advancements in narrowing the disparity between genders as per “the Lancet Public Health Journal”.

    What does the New Lancet report say?

    • On Health Disparities: The study highlights that women tend to suffer more from lower back pain, depression, and headaches, while men have shorter life expectancies due to higher rates of road accidents, cardiovascular diseases, and, recently, COVID-19.
    • On Health Burden: Women spend more time in poor health, while men are more likely to die prematurely from severe conditions.
    • Overall Global Analysis: The analysis examines differences in the 20 leading causes of illness and death globally, considering all ages and regions.

    What Causes the Differences in Diseases Between Women and Men? (Observations)

    • Biological Factors:
        • Hormonal Differences: Hormonal fluctuations in women, such as during menstrual cycles, pregnancy, and menopause, can influence susceptibility to certain conditions like migraines, depression, and autoimmune diseases.
        • Genetic Variations: Variations in genes and genetic predispositions may contribute to differences in disease susceptibility and severity between sexes.
        • Anatomical Variances: Physiological differences, such as in skeletal structure and hormonal regulation, can affect the manifestation of certain diseases like lower back pain and reproductive disorders.
    • Societal and Gender Norms:
        • Healthcare-Seeking: Societal norms and gender roles may influence healthcare-seeking behaviors, with men often less likely to seek medical attention for mental health issues due to perceived notions of masculinity.
        • Occupational Hazards: Occupational differences between genders can lead to varying exposures to health risks, with certain professions associated with higher rates of injury or exposure to harmful substances.
        • Socioeconomic Factors: Disparities in socioeconomic status can impact disease prevalence and outcomes differently for women and men.
    • Healthcare System Bias:
        • Diagnostic Bias: Gender biases in healthcare may result in underdiagnosis or misdiagnosis of certain conditions in women, leading to delays in treatment and poorer health outcomes.
        • Treatment Disparities: Differences in treatment approaches and responses may exist between sexes, with women sometimes receiving less aggressive treatment for cardiovascular diseases or being undertreated for pain conditions.
        • Research Bias: Historically, medical research has often focused on male subjects, leading to a lack of understanding of how diseases manifest and progress differently in women.
    • No Improvement in Care for Women Over Time
      • Stable Gender Gap: Despite overall health improvements, the disparity between male and female health conditions remains stable.
      • Conditions Affecting Women: Conditions like lower back pain and depressive disorders have shown little to no decrease over time compared to male-dominated conditions.
      • Reproductive Focus: Global health systems have historically focused on women’s reproductive health, neglecting other significant health issues affecting women.

    What Needs to Be Done (Way Forward)

    • Better Data Collection: Governments should consistently collect and categorize health data by sex and gender to better understand and address health disparities.
    • Targeted Health Interventions: Specific health interventions should be developed and implemented based on detailed sex and gender data.
    • Increased Funding: More financial resources should be allocated to underfunded conditions that disproportionately affect women, such as mental health.
    • Addressing Healthcare Bias: Efforts should be made to eliminate biases in healthcare to ensure women receive appropriate and timely treatment for their conditions.

  • Fewer women are being hired for leadership positions

    Why in the news?

    Although women’s representation in the workforce has grown over the years “LinkedIn’s Economic Graph data”  indicates that progress has stalled since 2022 and declined in 2024.

    What does the data show?

    • Representation of women in the workforce has increased over the years but progress has stalled since 2022 and declined in 2024. The promotion of women to senior and leadership roles has stagnated in recent years.
    • Sectors like healthcare, education, administrative, and support services have higher female representation in senior positions, while sectors like manufacturing, construction, oil, and gas have poor representation.

    Representation of women in the overall workforce and in senior positions 

    Entry and career progression of women  

     

    • Oil, Gas, and Mining: Among the lowest representation of women in leadership roles, at around 11%.
    • Construction: Very few women are represented, especially in senior roles.
    • Utilities: Women face significant barriers in advancing to leadership positions.
    • Wholesale: Low entry and career progression for women.
    • Manufacturing: Poor representation of women across all positions, including senior roles.
    • Transportation: Limited career progression opportunities for women.
    • Real Estate: Few women in leadership positions, with significant entry barriers.

    About the accommodation and other services  

    • Representation of women in senior roles within the accommodation and food services sector falls between 15% and 20%.
    • This sector exhibits a moderate level of female representation compared to other industries.
    • While not the highest, it surpasses sectors like oil, gas, mining, construction, utilities, wholesale, manufacturing, transportation, and real estate, where women hold just 11%-14% of leadership positions.
    • The data suggests there’s still room for improvement in increasing the number of women in leadership roles within the accommodation and food services sector.
    • Efforts to improve gender diversity and inclusion should be continued and perhaps intensified in this sector, aligning with broader industry and societal goals for gender parity in the workforce.

    Administrative and support services:

    • Women hold senior positions in administrative and support services at a rate of 22% to 30%, indicating a moderate level of representation compared to other sectors.
    • This sector demonstrates a higher level of female representation in leadership roles compared to industries like oil, gas, mining, construction, utilities, wholesale, manufacturing, transportation, and real estate, where women’s leadership roles range from 11% to 14%.
    • The education sector boasts the highest representation of women in senior positions at 30%, suggesting that sectors like administrative and support services still have room for improvement.
    • Efforts to promote gender diversity and inclusion within administrative and support services should be sustained, aiming for further increases in the representation of women in leadership roles.
    • Continued focus on addressing biases, societal norms, and structural barriers is essential to achieving greater gender parity and advancement opportunities for women within this sector.

    Way Forward

    • Efforts by policymakers and business leaders are needed to tackle challenges faced by women in reaching leadership roles, focusing on “women-led development”.
    • Stricter enforcement of laws such as the Companies Act, 2013, which mandates women directors on company boards. Between April 2018 and December 2023, 507 companies were fined for non-compliance, with 90% being listed companies.

  • Sundhnuksgigar Volcano erupts in Iceland

    Why in the News?

    Southwest Iceland witnessed the eruption of the Sundhnuksgigar volcano, triggering evacuations in the nearby areas.

    About Sundhnuksgigar Volcano 

    • Sundhnuksgigar is a row of craters just outside the town of Grindavik on the Reykjanes peninsula
    • It is situated on the Mid-Atlantic Ridge, a divergent boundary where the Eurasian and North American tectonic plates are moving apart.

    What is a Volcano?

    • A volcano is a fissure or vent in the Earth’s crust through which gases, molten rock materials (lava), ash, steam, sulphur dioxide etc., are expelled during an eruption.
    • These openings occur where the rock layers in the Earth’s crust are relatively weak.
    • Volcanic activity is categorized as an endogenic process, originating from within the Earth.
    • Depending on the explosivity of the volcano, various extrusive and intrusive landforms can be formed.

    Different types of volcanoes can be classified based on the frequency of eruption and the nature of the eruption:

    1.   Frequency of eruption:

    • Active volcanoes: Frequent eruptions in Pacific Ring of Fire: New Zealand, Southeast Asia, Japan, western Americas. Linked to plate tectonics, like Kilauea and Santa Maria. High seismicity, volcanic activity.
    • Dormant Volcanoes: These are not currently erupting but have the potential to erupt again in the future. An example is Mount Kilimanjaro in Tanzania, the highest mountain in Africa.
    • Extinct or inactive volcanoes: These have not erupted in the distant geological past. Dhinodhar Hill in Gujarat is an example.

    2.   Nature of Eruption:

    • Shield Volcanoes: Largest and least explosive volcanoes, formed from basalt lava. Often low in explosivity, except when water interacts. Hawaiian volcanoes exemplify this..
    • Composite Volcanoes: Volcanoes with cooler, thicker lava, built up through explosive eruptions. Layer ash, pyroclastic material, and lava flow. Examples: Mayon, Fuji, Rainier.
    • Calderas: The most explosive volcanoes, prone to collapsing inward during eruptions rather than building upwards. The resulting depressions are called calderas.
    • Flood Basalt Provinces: These volcanoes erupt highly fluid lava that travels long distances, covering vast areas with thick basalt flows.

    Reasons for Iceland’s Volcanism

    • Tectonic Activity: Iceland is situated on the Mid-Atlantic Ridge, where the Eurasian and North American plates diverge. This creates volcanic rift zones where magma rises to the surface, leading to eruptions.
    • Hotspots: Additionally, Iceland is positioned over a hotspot, contributing to heightened volcanic activity. Hotspots are areas where magma from the mantle rises towards the surface, fueling eruptions.
    • Subglacial Volcanism: Iceland’s volcanic activity is not limited to the surface; some eruptions occur beneath glaciers, leading to explosive interactions between lava and ice. These subglacial eruptions can produce powerful steam explosions, ash clouds, and catastrophic floods known as jokulhlaup.

    PYQ:

    [2021] Mention the global occurrence of volcanic eruptions in 2021 and their impact on the regional environment.

    [2013] Consider the following:

    1. Electromagnetic radiation

  • Still no sign of the language of equity and inclusion

    Why in the news?

    The ECI’s election announcement lacked sign language interpreters, highlighting the everyday exclusion of Deaf and Hard of Hearing (DHH) citizens.

    Present Issue:

    • India’s societal and structural framework often neglects the needs of Deaf and Hard of Hearing (DHH) citizens.
    • This exclusion is evident in various aspects of daily life, such as the absence of sign language interpreters during major public announcements and inadequate accessibility in public services.

    Sign Language versus Oralism

    • The Indian education system predominantly employs “oralism,” which emphasizes teaching deaf individuals to use their voices and lip-read, rather than using sign language.
    • This approach has been criticized for perpetuating social isolation and failing to remove barriers that hinder the integration of DHH individuals.
    • In contrast, using sign language has been shown to aid cognitive development and prevent linguistic deprivation.
    • Over 70 countries recognize their national sign languages legally, promoting accessibility and inclusion for deaf citizens.

    Present Scenario:

    • As per WHO estimates in India, there are approximately 63 million people, who are suffering from Significant Auditory Impairment; this places the estimated prevalence at 6.3% in the Indian population.
    • As per the NSSO survey, currently, 291 persons per one lakh population are suffering from severe to profound hearing loss (NSSO, 2001).
    • Of these, a large percentage are children between the ages of 0 to 14 years.

    What Does the 2011 Census Say?

    • The 2011 Census reported five million hearing-impaired individuals in India, while the National Association of the Deaf estimates 18 million.
    • Despite these large numbers, DHH individuals are often excluded from educational and employment opportunities. Only 5% of deaf children attend school, and they face prolonged graduation timelines due to oralist-focused curricula.
    • Government initiatives for employing the deaf are often ineffective, and there is a lack of ISL recognition, despite repeated demands and protests.

    The National Programme for Prevention and Control of Deafness

      • The program was initiated in the year 2007 in pilot mode in 25 districts of 11 States/UTs. It has been expanded to other districts too after the 12th five-year plan.
      • The Program was a 100% Centrally SponsoredScheme during the 11th Five-year plan. However, as per the 12th Five Year Plan, the Centre and the States will have to pool in resources financial norms of NHRM.
      • However, it falls short of addressing the quality of life for DHH individuals. This program has been expanded to 228 districts of 27 States / U.Ts in a phased manner.

    Objectives of the program:

    • To prevent avoidable hearing loss on account of disease or injury.
    • Early identification, diagnosis, and treatment of ear problems responsible for hearing loss and deafness.
    • To medically rehabilitate persons of all age groups, suffering from deafness.
    • To develop institutional capacity for ear care services by providing support for equipment and material and training personnel.

    Components of the Programme: 

    • Manpower Training & Development to grassroots level workers.
    • Service Provision Including Rehabilitation – Screening camps for early detection of hearing impairment and deafness.
    • Awareness Generation for early identification of the hearing impaired.
    • Monitoring and Evaluation.

    What Needs to be done?

    • Official Recognition of ISL: ISL should be recognized as an official language, and its use should be integrated into educational systems and public services. Teaching ISL in schools, colleges, and to the general public will promote inclusivity and fluency.
    • Inclusive Health Care: Health care systems need to be updated to ensure accessible communication for DHH patients. This includes training more ISL interpreters and reducing barriers for DHH individuals pursuing healthcare professions.
    • Media and Public Communication: Media channels should incorporate ISL interpretation and subtitles, especially in Hindi and regional languages. Government event announcements should have live ISL interpreters to ensure accessibility.
    • Employment Opportunities: Creating more employment opportunities for DHH individuals, beyond low-skilled jobs, is essential. This includes training and employing DHH individuals as ISL instructors and ensuring accessible workplaces.

    Conclusion: To ensure inclusivity for DHH citizens, India must officially recognise ISL, integrate it into education and public services, improve healthcare accessibility, and expand employment opportunities and mental health support.

  • Oldest Known Human Viruses Discovered In 50,000-Year-Old Neanderthal Bones

    Why in the News?

    • Researchers found traces of many present-day viruses in the bones of two Neanderthals who lived 50,000 years ago, providing a new perspective on their extinction.

    Breakthrough Study on Neanderthals 

    • Ancient viruses in Neanderthal DNA samples from skeletons found in Russia’s Chagyrskaya cave.
    • The study detected fragments resembling three modern viruses: adenovirus (common colds), herpesvirus (cold sores), and papillomavirus (genital warts).

    Health Impacts Inherited in Modern Human Beings:

    Modern humans inherit various health impacts from Neanderthals, including skin conditions, allergies, metabolism, nicotine addiction, mood disorders, sleep patterns, blood clotting, sense of smell, and UV radiation response.

    Who were the Neanderthals?

      • Neanderthals were a distinct species of hominins that lived in Europe and parts of Asia around 400,000 to 40,000 years ago during the Middle to Late Pleistocene Epochs.
      • Their evidence was first found in 1856 in the Neander Valley in present-day Germany.
    • Physical Features:
        • Neanderthals were robustly built, with a stocky and muscular frame adapted to cold climates.
        • They had large brains, comparable in size to modern humans, indicating advanced cognitive abilities.
        • Distinctive features included a prominent brow ridge, large nose, and a receding chin.
    • Social Life:
        • Neanderthals were skilled hunters and gatherers, using tools such as stone flakes, scrapers, and spears for hunting and butchering animals.
        • They utilized fire for cooking, warmth, and protection, as evidenced by the presence of hearths in their archaeological sites.
        • Evidence suggests they had complex social structures and engaged in rituals and symbolic behaviours, including burying their dead with grave goods.
    • Habitat and Distribution:
    • Neanderthals inhabited a wide range of environments, including open grasslands, forests, and even cold tundra regions.
        • Their range extended from Western Europe to Central Asia, with evidence of populations in regions such as Spain, France, Germany, Croatia, and the Middle East.
    • Interactions with Modern Humans:
      • Neanderthals coexisted with early modern humans (Homo sapiens) for thousands of years in Europe and Asia.
      • There is evidence of interbreeding between Neanderthals and modern humans, with genetic studies indicating that non-African humans carry about 1-2% Neanderthal DNA.
