How India is Serving the Growing Delhi Slum Population


As the population in India continues to increase steadily, so does the number of people living in slums. The country’s 2011 census revealed that the slum population currently stands at 65 million people, up from 52 million in 2001. 2,613 of India’s 4,041 towns are classified as slums. In the territory of Delhi, where capital city New Delhi is located, 1.8 million of the 22 million residents live in 22 slums.

The India census defines the term “slum” as an area resided in yet unsuited for human habitation. These places are deemed unfit if they are a hazard to human health and safety due to lack of space, ventilation, cleanliness and other factors. These areas also lack hygienic drinking water facilities, functional bathroom areas and plumbing.

The Delhi slum population lives day-to-day without the basic amenities of electricity, plumbing and gas. Most of the residents are unemployed or daily wage workers, making less than the equivalent of one U.S. dollar a day.

In the 2011 census, slums are categorized in three different subgroups – notified, recognized and identified. Notified and recognized slums are legally established, while identified slums do not hold official slum status by the Indian government. The residents living in identified slums do not have access to legal protection and civic services.

Identified slums must have a population of at least 300 people with 60-70 tenements. Over one million of the growing Delhi slum population reside in identified slums and receive no aid from the government.

With the drastic population increase of the slums, the few resources these areas have are becoming even more depleted and run down.

However, not all of the census’ findings are negative. During the 10-year period under review, the Indian slum population grew at a rate slower than the general urban population. The average household size in slums is no larger than the average household size of urban areas. Slum literacy rate rose from 72.2 percent in 2001 to 77.7 percent in 2011. This is still below the overall Indian literacy rate of 84.1 percent.

WaterAid India is an organization that works to help some of the main issues the growing Delhi slum population is facing: lack of water, sanitation and hygiene, abbreviated as WASH. WaterAid aims to increase Delhi’s access to WASH through deliveries, supporting communities to manage and monitor their own services and advocating for improved WASH conditions from the government.

Asha is another organization seeking to aid Delhi’s slum residents. Asha provides many services for slum dwellers such as access to healthcare, financial services and education. They seek to meet basic environmental and healthcare needs of the population and empower and educate slum dwellers to change their own futures. These are just two of the many organizations seeking to improve the lives of the growing Delhi slum population.

Major Diseases in Luxembourg in Line with Global Trends


According to the 2014 Euro Health Consumer Index, Luxembourg ranks eighth in Europe for comprehensive healthcare. This makes sense, given the fact that Luxembourg is the wealthiest country in the EU. Even so, Luxembourg still faces diseases that threaten its citizens. This article examines the most major diseases in Luxembourg and what measures have been taken to advance patient care and lower mortality rates.

Most prevalent of the major diseases in Luxembourg is cardiovascular disease. According to the statistics portal funded by the Government of Luxembourg, in the year 2014, cardiovascular diseases caused approximately 31.2 percent of deaths. Ischemic heart diseases, as well as other forms of heart disease such as heart failure and cardiac arrest, were the leading causes of death within this category.

Cancer causes 30.6 percent of deaths in the country. Cancers of the digestive system accounted for the highest rate of death in this category, followed closely by cancers of the respiratory system. These two cancers alone cause 52.5 percent of cancerous deaths in Luxembourg.

Respiratory diseases account for 6.97 percent of deaths. Chronic lower respiratory diseases, such as asthma, bronchitis, emphysema, influenza and pneumonia result in the most deaths, 76 percent, within this category.

The top diseases in Luxembourg align with global health trends. The World Health Organization found that cardiovascular diseases are the most deadly diseases all over the world, contributing close to 15 million of the 54 million deaths in 2015.

Luxembourg’s government has taken steps to combat some of these diseases in an effort to lower mortality rates. For instance, the Ministry of Health has implemented a four-year national cancer plan from 2014-2018. This plan is designed to develop cancer prevention methods and improve recovery processes.

Like so many other countries around the world, Luxembourg has made it its mission to find a way to not only combat the major diseases but also to better the lives of its citizens.

Major Diseases in Moldova, One of Europe’s Poorest Countries

Diseases in Moldova
The Republic of Moldova is a parliamentary republic that has implemented an ambitious economic reform program. Agriculture dominates the economy, and the country depends on imports for energy needs. Moldova remains the poorest country in the World Health Organization’s (WHO) European region, although it has made significant progress in economic growth. It had an estimated per capita gross national income of $1810 USD in 2010, according to the World Bank. Life expectancy estimates are two to five years higher than the other countries in the Commonwealth of Independent States (CIS). Most deaths are a result of diseases in Moldova. Both communicable and noncommunicable diseases have been increasing steadily since the country’s independence in 1991.

The most common causes of death in the country are circulatory system diseases, followed by cancer and digestive system diseases. Most of the deaths caused by diseases in Moldova are related to heavy alcohol and tobacco use, although chronic liver disease and cirrhosis rates have decreased over the last five years.

Key challenges in the fight against diseases in Moldova also include HIV/AIDS and tuberculosis. The prevalence of tuberculosis has been rising since 1990 and has more than doubled to date, reaching 182 per 100,000 people. The most dramatic rate increase is in children.

The deadliest risk factors for diseases in Moldova are dietary risks, high systolic blood pressure and high body mass index. Lesser risks include tobacco smoke, alcohol and drug use and high fasting plasma glucose.

While Moldova has quite a bit of work to do, being number one in death rates due to liver diseases, number five in prostatic hypertrophy and number seven in both coronary heart disease and congenital anomalies, it is on the road to better lives for its citizens. It is pushing to reduce poverty, with many Millennium Development Goals being developed and maintained. The country is also working to develop agricultural sustainability and many different ways of importing medicine and products that will help with rates of diseases in Moldova.

How to Improve Health in Developing Countries


Despite the modern advancements of this era, developing countries still have poor access to quality, cost-effective healthcare. Attempting to close the socioeconomic gap created by poverty, there are three initiatives that governments and national organizations can take to improve health in developing countries.

3 Ways to Improve Health in Developing Countries

  1. Investing in Education: One of the most important ways to improve health in developing countries is by educating citizens. Educating people enables them to obtain safer jobs, increased health literacy, take preventive healthcare measures, avoid riskier health behaviors and demand better-quality health services.This is especially true for women living in developing countries, from girls entering puberty to pregnant mothers. Most deaths that occur in developing countries are neonatal, or during the first five years of life. By “providing formal or vocational education, adequate family planning, and antenatal services can break the cycle of poverty and empower women”, this type of education would begin providing soon-to-be mothers with the necessary knowledge to keep her family, future children, and self both safer and healthier.
  2. Increasing Health Benefits for the Poor: Poorer countries receive much lower health benefits than richer countries. In developing areas, the poor are subjected to higher risk of contracting diseases and lower access to quality healthcare. This is solely due to the cost of medicine, treatments and vaccinations. Through the creation of targeted systems that strategies identify who is poor and eligible for lower-cost health care. Another attribute of this system is directing programs directly towards lesser developed areas. This targeting system has the potential to “eliminate poverty at less than 10 percent the cost of development programs that do not discriminate between poor and rich”. These systems are done on different levels: most specifically they target individually poor, geographically poor, what diseases need to be prioritized, and the age of those that need health care the most.
  3. Promoting Primary and Essential Healthcare: A way to improve health in developing countries involves governments providing cost-effective health packages for everyone. An example of this would be Ethiopia and Malawi, where governments have focused on achieving universal vaccine coverage, developing cleaner water supplies and creating better sanitation practices.On a broader scale, as part of the Sustainable Development Goals, the U.N. has agreed to pursue universal healthcare by 2030. The initiative to create universal healthcare includes “access to quality essential healthcare services and access to safe, effective, quality and affordable essential medicines and vaccines for all”. By making availability universal, resources can be directed towards primary-level facilities of care that strengthen the overall treatments that people will be receiving.

These are not the only ways to improving health in developing countries. Governments and organizations have taken many different initiatives to closing the socioeconomic gap. With the Sustainable Development Goals, there should be a significant increase of developed countries contributing to establishing safe, quality healthcare systems.

Top Diseases in Azerbaijan


The disease is rampant in Middle Eastern and Eastern European countries. Azerbaijan, located just south of the Caucasus Mountains and home to 9.6 million people, is no exception. Every day, these people are affected by chronic diseases in Azerbaijan, which ranges from heart disease and cancer all the way to infectious diseases and HIV/AIDS. Here is a list of the top diseases in Azerbaijan that threaten local citizens.

Cardiovascular Diseases

According to the World Health Organization (WHO), 54 percent of deaths in Azerbaijan are caused by cardiovascular diseases. Between 1990 and 2013, the annual mortality rate from cardiovascular diseases in Azerbaijan has increased by 18.2 percent, with an average of 0.8 percent per year. The most severe of cardiovascular diseases in Azerbaijan is Ischemic Heart Disease. However, the number of fatal strokes in Azerbaijan has increased by 24 percent since 1990, and the number of deaths caused by Hypertensive Heart Disease has increased by 33 percent since 1990. Cardiovascular diseases are by far the number one cause of death in Azerbaijan.

Chronic and Lower Respiratory Diseases

Data shows that of the communicable diseases in Azerbaijan, chronic respiratory diseases are the most dangerous. From the list of communicable diseases, lower respiratory infections make up for half of the deaths depending on age group, and the annual mortality rate sharply increases for those over the age of 55. However, things are looking better for chronic respiratory diseases in Azerbaijan; since 1990, the annual mortality rate for lower respiratory infections has decreased by 73 percent.

HIV/AIDS

Although HIV/AIDS does not make up for a large percentage of harm, it is still a very dangerous disease in Azerbaijan. HIV/AIDS has one of the fastest-growing annual mortality rates of any other disease in Azerbaijan. Between 1990 and 2013, the number of deaths caused by HIV/AIDS has increased by 3,247 percent. As of 2015, the number of people in Azerbaijan living with HIV is estimated to be around 11,000, and it is predicted that the number will increase.

Diseases in Azerbaijan are extremely prevalent and have a large effect on citizens’ lives. Organizations such as WHO, UNICEF, and UNAIDS are all working closely together in order to properly treat current diseases and prevent future deaths.

Noncommunicable Diseases: The Impending Global Health Crisis


The WHO’s “Ten years in public health 2007-2017” report chronicles the “evolution of global public health” over the past decade. The report emphasizes the escalation of chronic noncommunicable diseases (NCD) as the largest threat to global health.

Chronic NCDs are categorized as diseases that progress slowly. The four main NCDs are cancer, cardiovascular disease, diabetes and chronic respiratory disease, all of which share common risk factors abundant in non-health sectors. NCDs have only recently been recognized as a main component in the impending global health crisis. These chronic diseases share four risk factors: tobacco use, excessive alcohol use, unhealthy diet and minimal physical activity.

In 2015, the World Health Organization (WHO) reported 70 percent of global deaths were due to NCDs (39.5 million out of 56.4 million). Out of the 39.5 million NCD fatalities, 30.7 million occurred in low and middle-income countries.

Health systems traditionally rely on curing individual disease as they arise. However, current health systems are not sustainable due to insufficient disease management and care. Access to disease treatment is becoming unavailable for millions of individuals, including affluent people in wealthy countries.

A study released by the World Economic Forum states that diabetes cost the global economy nearly $500 billion in 2010 and this is projected to increase to $745 billion by 2030. Newly approved cancer treatments average $120,000 per person, causing medical care to be “unaffordable for even the richest countries in the world.”

These high costs have four severe implications:

  1. They undermine the traditionally ethical ideal that healthcare should be available to everyone;
  2. The need for social protection becomes obvious when a person has to spend much as 60 percent of their income to get diabetes medication;
  3. Prevention becomes the foundation of global health;
  4. High costs clarify that no economy can outlast the NCD global crisis by investing solely in treatment services.

The WHO report ‘Ten years in public health 2007-2017’ estimates that 40 million people die each year from NDCs, “accounting for 70 percent of all deaths worldwide.” According to Margaret Chan, Director-General at WHO, chronic noncommunicable diseases have surpassed infectious disease as the leading cause of death worldwide.

The WHO’s newly established ‘Health Emergencies Programme’, enables faster response to global pandemics and emergencies. The programme collaborates with various countries and partners to “prepare for, prevent, respond to and recover from all hazards that create health emergencies, including disasters, disease outbreaks and conflicts.” It is also focused on community engagement and increasing disease prevention in public health services.

Chan urges the world to focus on implementing universal health care to reduce noncommunicable diseases. It is the ultimate expression of equality, ensuring no one is left behind.

Progress Toward Eradicating Ebola


Eradicating Ebola is the global community’s next step in ensuring worldwide health. The disease is rare but extremely contagious, and causes internal and external bleeding as well as a severe fever. As soon as the virus enters the body, it weakens the immune system by attacking immune cells. In time, it causes blood vessels to carry less blood, which results in organ failure and eventual death.

Also known as Ebola hemorrhagic fever or Ebola virus, the disease is spread through direct contact with bodily fluids or objects that have been contaminated by bodily fluids, such as medical needles. It can also be contracted through contact with infected animals, specifically bats and primates.

There have been a number of Ebola cases internationally but the disease has mainly remained in regions of West Africa. The disease originated in 1976 in the Democratic Republic of the Congo, but it was Guinea, Liberia, and Sierra Leone that witnessed the largest Ebola epidemic in 2014 through 2016. An estimated 28,616 people contracted the disease and this resulted in 11,310 deaths.

Fortunately, the presence of Ebola has been contained since the outbreak. In 2015, researchers from the World Health Organization began testing a vaccine in Guinea, which returned with a 100 percent success rate. This vaccine was developed through a “ring vaccination” approach. The approach separated patients and their immediate contacts from the general public.

The vaccination report was released in December 2016. As Marie-Paule Kieny, lead author of the report, states: “While these compelling results come too late for those who lost their lives during West Africa’s Ebola epidemic, they show that when the next Ebola outbreak hits, we will not be defenseless.” Although the vaccine demonstrates progress in eradicating Ebola, it is in need of additional safety research before it can be formally licensed.

Another development in eliminating Ebola comes from a group of Canadian researchers. The group administered a drug known as Interferon Beta-1a to patients infected with Ebola. The drug, which is used to treat hepatitis B and C, had surprisingly effective results. “After 21 days, 67 percent of the Interferon-treated Ebola patients were still alive, compared to just 19 percent of the others,” reports Tom Blackwell from The National Post.

Although more research must be conducted regarding Interferon Beta-1a, findings look promising. The vaccine also demonstrates significant progress in eradicating Ebola, a disease that is now destined to become an element of the past.

Top Three Diseases in Israel

Top 3 Diseases in Israel
While Israel has been able to lower the number of deaths caused by diseases, many conditions in Israel are still prevalent. The death rates from certain diseases in Israel have declined by 80 percent since the 1970s, but there is always room for improvement. Here are the top three diseases in Israel.

Top Three Diseases in Israel

  1. Cancer: Cancer, the major killer in Israel, caused almost one-quarter of total deaths in Israel in 2011. Even though the cancer rate is relatively low compared to other countries, cancer is still a primary cause of death. The most common cancer among Israeli men is lung cancer, which is primarily caused by tobacco smoking. The most common cancer among Israeli women is breast cancer. About 4,500 Israeli women are diagnosed with breast cancer each year, and 900 dying from it. However, according to the Israel Cancer Association, the number of women surviving breast cancer is steadily on the rise thanks to research and technology able to detect early signs. It has also been reported that the lung cancer rate among men is lower than most countries.
  2. Coronary Heart Disease: Coronary Heart Disease is the second most prevalent cause of death in Israel. Together, cancers and heart disease account for 40 percent of deaths. However, like cancer, heart disease in Israel is being contained. The death rate from heart disease in Israel has dropped by 50 percent since 1998, partly due to declines in smoking and national campaigns against obesity, diabetes and hypertension. The people of Israel have been willing to change their lifestyles to prevent heart disease. There are also reliable ambulance services in Israel to respond to any emergency.
  3. Diabetes: Diabetes is the next leading cause of death after cancer and heart disease. Compared to other countries, deaths from diabetes are high in Israel. But the country has tried a number of ways to defeat diabetes including using an artificial pancreas, medical smartphones and glucose-sensing enzymes. Researchers have also been looking for a cure with the help of the Juvenile Diabetes Research Foundation and the Israel Science Foundation. Scientists are also working on an antibody to block killer cells that destroy helpful cells in the pancreas.- Emma MajewskiPhoto: Flickr

Poverty and Epidemiology of the Top Diseases in France

Poverty and Epidemiology of the Top Diseases in France
It is widely known that developing nations are plagued by different diseases than industrialized nations. While most global deaths by non-communicable diseases occur in poverty-stricken nations, the citizens of industrialized nations also typically die of similar illnesses. In fact, 88 percent of people in high-income countries die of conditions such as heart attack, stroke, cancer and diabetes.

France, a wealthy nation with the fifth largest economy in the world, follows this trend. The top diseases in France are cancer, neuropsychiatric conditions (such as Alzheimer’s), cardiovascular disease and diabetes.

Regardless of a country’s income, poverty impacts the epidemiology of disease. The basic relationship between poverty and health is rather straightforward: with lower incomes, the poor struggle to afford quality food and medical treatments. For example, one study suggests that not having access to fresh fruits and veggies may account for the increased rate of gastrointestinal cancers in the poor. Along with a higher infection rate, poor people with cancer often suffer more pain from the disease.

In addition, the impoverished typically have less knowledge about healthy lifestyles and engage in risky activities, such as smoking. Reuters presented a study showing that poverty and poor education correlate directly with the risk of heart disease. Another link between poverty and epidemiology is that poor people typically have weaker support systems. This makes caring for chronic conditions such as diabetes challenging.

While this may be surprising, 14 percent of the Frenh population actually lived below the poverty line in 2012. The unemployment rate was at 9.8 percent in 2014. About 26 percent of French people said they did not follow through on at least one medical treatment due to finances. Those in the lowest quintile of income were three times more likely to not seek medical treatment than those in the top quintile of income. Furthermore, people with higher incomes were more like to see a specialist doctor (such as a cardiologist or oncologist).

Healthcare affordability is not the only connection between poverty and disease. Trends in substance abuse among lower income citizens are also connected with the top diseases in France. Alcohol and tobacco use can be linked to the most avoidable deaths in the country. Alcohol and tobacco are typically used more often in areas with lower socioeconomic statuses. In fact, the unemployed accounted for increasing smoking rates from 44 percent to 50.8 percent between 2005 and 2010. These trends may shed light on the high prevalence of breast and colon cancer in France.

Fortunately, France has universal healthcare; 77.4 percent of healthcare costs are covered by this system. The remaining costs are either out of pocket expenses or covered by voluntary health insurance. Overall, France is a healthy country compared to other European countries. The average life expectancy is eight years longer than other countries in that region. Healthy life expectancy is five years longer.

There are still issues in regards to coverage and access. Poorer people in France are missing treatments because of finances. Consequently, the country is making an effort to reduce the financial burden of the top diseases in France. The government has begun offering free breast and colorectal cancer screenings to older adults. These two cancers account for 16 percent of all cancer deaths in France. Thirty percent of all breast cancer cases in 2012 were detected through the free screenings.

While France is one of the wealthiest nations in the world, citizens are still vulnerable to the effects of poverty. However, the country realizes where healthcare falls short and is working towards protecting vulnerable populations. Lessons learned in France can be used as a model for other nations. Hopefully, the epidemic of chronic diseases will be solved so that today’s developing nations will not have the same plight in the future. Good solutions can transcend culture and help people all over the world.

5 Ways Poverty Affects the Developing Brain

Poverty_ Brain
Living in poverty can coincide with numerous social problems — childhood neglect, violence and malnutrition, to name a few. However, there are studies being conducted that show how poverty may potentially affect the developing brain and the cognitive abilities of children. Here are five ways that research is currently showing how poverty affects the brain.

5 Ways Poverty Affects the Developing Brain

  1. Brain scans of children who grow up in poverty reveal that, overall, their brains develop less gray matter in the frontal and parietal lobe. Serving as the control center for the brain, the frontal lobe manages accessory cognitive functions like planning, focusing, problem-solving, organizing and controlling impulses. The parietal lobe is responsible for processing sensory information. The Institute for Research on Poverty at the University of Wisconsin-Madison reports that less gray matter in these areas, as seen on Magnetic Resonance Imaging (MRI) scans, can impede children’s abilities to learn even before they enter kindergarten. The research demonstrated that throughout brain growth in the first three years of life, children in a lower socioeconomic status (SES) had significantly lower brain volumes than their higher SES counterparts.
  2. Brains influenced by poverty show a significant decline in cognitive abilities related to memory, reading and language. This is evident through children’s performances on neurocognitive tests as well as brain activity on electroencephalograms (EEG). Research performed by Natalie H. Brito, a postdoctoral research fellow at Columbia University, combined this information along with studies of families to link cognitive abilities to circumstances like neglect, household stress and economic status.
  3. Similar studies conducted by Elizabeth Sowell from The Children’s Hospital in Los Angeles and Kimberly Noble from Columbia University demonstrate that brains of children in the lowest income brackets (families who make less than $25,000 annually) have six percent less surface area than children from higher income bracket families.
  4. Developing brains exposed to severe poverty also show smaller hippocampi (the portion of the brain that is central to stress response, memory and learning). Existing research supports the fact that parental caregiving is an important factor in the hippocampal development and childhood wellbeing. Combined with poverty, stressful life experiences result in a lower volume of hippocampi.
  5. A smaller amygdala is also characteristic of growing brains that have been exposed to poverty. Responsible for emotional processing and social information, a smaller amygdala can result in childhood depression and mood and behavioral problems.

The symptoms of poverty include many factors that can contribute to the modifications of a developing child’s DNA – malnutrition, exposure to violence, lack of cognitive stimulation or less time bonding with parents. Rather than present the solution as “eliminate all poverty,” remedies should focus on policies and programs that seek to mitigate the influence of poverty’s external factors. Research in this area is still developing, as scientists and doctors continue to monitor the neuroscience of poverty as children grow into adults.

Brito agrees when she says, “When I talk to a lot of our participants – always worrying about where their next paycheck comes from, always worrying about if they have enough resources – it takes away time and energy from having meaningful interaction with your child. So in developing countries, making sure that those policies are in place so that parents are available to just interact with their child, just play with their child without worry, really does make a big difference.”
