Washington D.C, Nov 7: A study states that more physical activity and higher intensities of exercise could decrease the risk of death in older women from any cause.

Lack of exercise or physical activity is estimated to cause as many deaths each year as smoking.

Current guidelines recommend at least 150 minutes a week of moderate intensity physical activity, or 75 minutes a week of vigorous-intensity aerobic physical activity (or a combination of the two), and muscle-strengthening exercises two or more days a week.

The study, led by investigators at Brigham and Women's Hospital, investigated physical activity of women measured over seven days using a wearable device called a triaxial accelerometer.

Moderate to vigorous intensity physical activity (e.g. brisk walking) was associated with 60-70 percent lower risk of death at the end of the four-year study among the most active women, compared to the least active.

"The fact the physical activity lowers mortality rate is nothing new - we have many studies showing this. However, previous studies have primarily relied on self-reported physical activity, and self-reports tend to be imprecise. Based on these self-report studies, we know that physical activity is associated with a 20-30 percent reduction in mortality rates, comparing the most with the least active. Using device-measured physical activity in the present study, we observed a 60- 70 percent risk reduction larger than previously estimated from self-report studies. For context, non-smokers have about a 50 percent reduction, compared with smokers," stated I-Min Lee, MBBS, ScD, associate epidemiologist at Brigham and Women's Hospital, and first author of the study.

"This study supports current guidelines for physical activity, such as those from the federal government and the American Heart Association, that emphasize moderate-intensity physical activity. It also adds to existing evidence that can inform upcoming physical activity guidelines over time."

This is one of the first studies to investigate physical activity, and a clinical outcome, using the newer generation triaxial wearable devices which have increased sensitivity to recognize physical activity and are capable of more precise measurements than the previously used uniaxial devices, or studies relying on self-reports only.

"We used devices to better measure not only higher intensity physical activities, but also lower intensity activities and sedentary behavior, which has become of great interest in the last few years," stated I-Min Lee, MBBS, ScD.

Data were analyzed from 16,741 participants (average age 72) from the Women's Health Study who wore the device for at least 10 hours a day, on at least four out of seven days.

Light physical activity, such as slow walking, was not associated with lower death rate during the study. Researchers note that light activity may be beneficial for other health outcomes not reported in this paper.

The findings have been published in Circulation.

Washington, Jun 20: Pregnant and postpartum women are usually at a high risk of depression and anxiety - one in seven women struggle with symptoms in the perinatal period and the coronavirus pandemic is exacerbating those struggles according to a recent study.

The study was published in Frontiers in Global Women's Health, which found that the likelihood of maternal depression and anxiety has substantially increased during the health crisis.

"The social and physical isolation measures that are critically needed to reduce the spread of the virus are taking a toll on the physical and mental health of many of us," said Dr. Margie Davenport of the University of Alberta, Canada, who co-authored the study.

For new moms, those stresses come with side effects.

"We know that experiencing depression and anxiety during pregnancy and the postpartum period can have detrimental effects on the mental and physical health of both mother and baby that can persist for years," said Davenport.

Such effects can include premature delivery, reduced mother-infant bonding, and developmental delays in infants.

The study surveyed 900 women - 520 of whom were pregnant and 380 of whom had given birth in the past year - and asked about their depression and anxiety symptoms before and during the pandemic.

Before the pandemic began, 29 percent of those women experienced moderate to high anxiety symptoms, and 15 percent experienced depressive symptoms. During the pandemic, those numbers increased - 72 percent experienced anxiety and 41percent experienced depression.

Because lockdown measures have affected daily routines and access to gyms, researchers also asked women whether their exercise habits had changed. Of the women surveyed, 64 percent reduced their physical activity since the pandemic began, while 15 percent increased and 21 percent experienced no change.

Exercise is a known way to ease depression symptoms, so limited physical activity may result in an uptick in depressive symptoms. Indeed, the study found that women who engaged in at least 150 minutes of moderate physical activity a week had significantly lower symptoms of depression and anxiety.

The findings are somewhat limited given the fact that researchers could not survey women before the pandemic began (since they could not know a pandemic would occur). The women surveyed could only offer their pre-pandemic symptoms in hindsight.

Also, while the researchers asked women about their symptoms using validated measures, only mental health care professionals can validly diagnose an individual with depression or anxiety.

The study was specifically interested in the impact of COVID-19 on new moms, but Davenport says maternal mental health is a critical issue no matter the time.

"Even when we are not in a global pandemic, many pregnant and postpartum women frequently feel isolated whether due to being hospitalized, not having family or friends around or other reasons," she said.

"It is critical to increase awareness of the impact of social (and physical) isolation on the mental health of pregnant and postpartum women," Davenport added.

Increased awareness makes diagnosis and treatment - the ultimate goal - more likely.

Global poverty could rise to over one billion people due to the COVID-19 pandemic and more than half of the 395 million additional extreme poor would be located in South Asia, which would be the hardest-hit region in the world, according to a new report.

Researchers from King's College London and Australian National University published the new paper with the United Nations University World Institute for Development Economics Research (UNU-WIDER) said that poverty is likely to increase dramatically in middle-income developing countries and there could be a significant change in the distribution of global poverty.

The location of global poverty could shift back towards developing countries in South Asia and East Asia, the report said.

The paper, 'Precarity and the Pandemic: COVID-19 and Poverty Incidence, Intensity and Severity in Developing Countries,' finds that extreme poverty could rise to over one billion people globally as a result of the crisis.

The cost of the crisis in lost income could reach USD 500 million per day for the world's poorest people, and the intensity and severity of poverty are likely to be exacerbated dramatically.

The report said that based on the USD 1.90 a day poverty line and a 20 per cent contraction, more than half of the 395 million additional extreme poor would be located in South Asia, which would become the hardest hit region in the world mainly driven by the weight of populous India followed by sub-Saharan Africa which would comprise 30 per cent, or 119 million, of the additional poor.

The report added that as the value of the poverty line increases, a larger share of the additional poor will be concentrated in regions where the corresponding poverty line is more relevant given the average income level.

For instance, the regional distribution of the world's poor changes drastically when looking at the USD 5.50 a day poverty line the median poverty line among upper-middle-income countries.

At this level, almost 41 per cent of the additional half a billion poor under a 20 per cent contraction scenario would live in East Asia and the Pacific, chiefly China; a fourth would still reside in South Asia; and a combined 18 per cent would live in the Middle East and North Africa (MENA) and in Latin America and the Caribbean (LAC), whose individual shares are close to that recorded for sub-Saharan Africa.

India plays a significant role in driving the potential increases in global extreme poverty documented previously, comprising almost half the estimated additional poor regardless of the contraction scenario, the report said.

Nonetheless, there are other populous, low and lower-middle- income countries in South Asia, sub-Saharan Africa, and East Asia and the Pacific accounting for a sizeable share of the estimates: Nigeria, Ethiopia, Bangladesh, and Indonesia come next, in that order, concentrating a total of 18 19 per cent of the new poor, whereas the Democratic Republic of Congo, Tanzania, Pakistan, Kenya, Uganda, and the Philippines could jointly add 11 12 per cent.

Taken together, these figures imply that three quarters of the additional extreme poor globally could be living in just ten populous countries.

The report added that this high concentration of the additional extreme poor is staggering , although not necessarily unexpected given the size of each country's population.

On one hand, data shows that three of these ten countries (Ethiopia, India, and Nigeria) were among the top ten by number of extreme poor people in 1990 and remained within the ranks of that group until 2018.

Despite this crude fact, two of these countries have managed to achieve a sustained reduction in their incidence of poverty since the early 1990s, namely Ethiopia and India, reaching their lowest poverty headcount ratio ever recorded at about 22 and 13 per cent, respectively. Nonetheless, the potential contraction in per capita income/consumption imposed by the pandemic's economic effects could erase some of this progress.

The researchers are now calling for urgent global leadership from the G7, G20, and the multilateral system, and propose a three-point plan to address the impact of the COVID-19 on global poverty quickly.

Professor of International Development at King's College London and a Senior Non-Resident Research Fellow at UNU-WIDER Andy Sumner said the COVID-19 crisis could take extreme poverty back over one billion people because millions of people live just above poverty.

Millions of people live in a precarious position one shock away from poverty. And the current crisis could be that shock that pushes them into poverty.

Professor Kunal Sen, Director of UNU-WIDER said the new estimates about the level of poverty in the world and the cost of the COVID-19 pandemic to the world's poor are sobering.

We cannot stand by and see the hard work and effort of so many be eradicated. We will know what the real impact is in time, but the necessary action to ensure we achieve the Sustainable Development Goals by 2030 needs to be planned now, Sen said.

The Lockdown is not a cure but a critical strategy to prevent the geographical spread of COVID-19.

While pandemics at this level involves actual life threatening situations for individual's or significant others in one's immediate circle, it envisages a marked disruption in routine life. Even after the pandemic has been contained and will come to pass; it's aftermath will leave a trailblazer which demands planning and implementation of a post pandemic reconstruction of society with potentially traumatic experiences varying in intensity, multiplicity and duration.

Degree of Trauma

It would do well for each one of us to realise that the pandemic is "potentially traumatic", since not everyone will experience COVID -19 as a traumatic event in their lives. Yet, there will be those who may develop post pandemic stress reactions, depression and related dysfunction and pathological reactions while still other exhibit healthy reactions to the same set of circumstances.

"Psychological reactions to the pandemic can be distilled into four distinct prototypical patterns, namely, Resilience, Recovery, Chronic and Delayed patterns which may vary in intensity, multiplicity, and duration. Resilient individual have an ability to bounce back from adversity and experience modest or little disruption in normal functioning and are able to maintain a relatively stable, healthy levels of psychological functioning even after enduring the pandemic. Recovery pattern is characterised by relatively rapid reduction in symptoms and return to normal functioning whereas chronic pattern is characterised by symptoms and dysfunction of a long duration," says Pune-based military psychologist Lt Col Dr Samir Rawat.

Challenges at the Individual and Community Levels

From a psychological perspective, post pandemic reconstruction would entail catering to the problems, concerns and needs of those adversely impacted by the COVID -19 with stress symptoms typically characterised by individual's experiencing an overwhelming trauma of the pandemic (for example, recurring nightmares/ breaking into a cold sweat, flashback of stressful events, increasing irritability, low frustration tolerance or emotional numbing).

It could also manifest in depressive symptoms which may result in lack of interest or diminished pleasure in activities and things which you earlier liked to do, feelings of worthlessness or even survivor guilt in case of a loss of a loved one due to COVID-19, fleeting thoughts of death and suicidal ideation. Physical symptoms, on the other hand could be a decrease in appetite, weight and sleep problems, inability to focus and lack of concentration.

Undoubtedly, the pandemic will cause a financial loss of varying magnitude to many, especially the marginalised and economically disadvantaged strata of daily wage earners; it will also lead to loss of jobs (already beginning to show), homelessness, occupational difficulties and new challenges in interpersonal relations at work and on the home front, besides physical health problems and psychological barriers with new norms of accepted social behaviour (social distancing, handshakes, an obsession for cleanliness to name a few).

Emotional battles

Many factors may influence whether individuals come out stronger and more resilient or surrender to the pandemic. Emotion Regulation is one such long term critical factor that can play an important role in contributing to varying degrees of adaptation with negative or positive outcomes. While we know that primary emotions are fear, anger, disgust, joy, anticipation, acceptance, sadness and surprise, other basic emotions include wonder, love, desire, joy, hatred, sadness, attachment, disgust, rage and even expectancy .

To be able to regulate these emotions and avoid negativity , especially on social media platforms is likely to increase efforts in emotion regulation which involves initiating, increasing or maintaining an emotional response.

This means by regulating or on the other hand by stopping, decreasing or avoiding an emotional response, that is, by down-regulating, depending on the individual's objectives and goals or his /her ability to regulate emotions in the valued and given direction.

"One of the best ways to regulate emotions is through cognitive restructuring wherein we change the way we think; after all it is not the event but the interpretation of the event which is perceived as stressful and finding meaning promotes resilience and reduces risk and vulnerability to stress," advises Dr Rawat.

Adding, "Clearly, we need to have a psychological plan to prevent, mitigate and minimise negative outcomes by post pandemic reconstruction of society at an individual and community level all over the country; this has to be integrated by all leaders across verticals in diverse domains."
