London, There is no correlation between obesity and how close you live to fast food restaurants or gyms as previous studies have indicated that these factors may be important in adult obesity, say researchers.
According to the study, published in the International Journal of Obesity, the areas where we live are known to be important for our health. For example, obesity is more prevalent in deprived neighbourhoods.
Deprived neighbourhoods are typically defined by low socio-economic levels, e.g., low average income and high unemployment rates, the researchers said.
The reason why obesity is more prevalent in such neighbourhoods have been a topic of interest among both researchers and policymakers for a long time, and commercial facilities, like fast food outlets and physical activity facilities, have attracted much research attention and debate.
"However, our large-scale study in Sweden, using longitudinal national registry data of more than 1.5 million adults, did not find a statistically significant association between these two types of facilities and obesity", explained Kenta Okuyama from the Lund University in Sweden.
The researchers said that it is unlikely that the availability of fast food outlets or lack of gyms is causes of obesity in Swedish adults.
Although reducing fast food outlets or introducing physical activity facilities might, in theory, promote healthy eating and exercise, it may not be very effective in all countries and regions.
"Because the contexts vary by its culture and lifestyle that may affect how often people utilize these facilities in their daily lives", Okuyama said.
During the findings, the researchers did show a correlation between neighbourhood deprivation and obesity.
"The next goal is to investigate further what other factors can possibly impact the risk of obesity in Sweden", Okuyama concluded.
New Delhi, May 15 (IANS) Delhi Health Minister Satyendar Jain on Friday said while earlier it was believed that the coronavirus will die with the rise in mercury, but even in countries with very high temperature the infection is increasing and this shows that we have to learn to live with COVID-19.Speaking to the media, Jain said while the cases are increasing, the rate of increase is just five per cent."There was a time when we all thought that this pandemic will be over by May 1 due to the summer. But now we have seen that in the Latin American countries also the pandemic is increasing. The temperature of these countries is very high. This shows that we have to learn to live with COVID-19," Jain said.He also said that in the last two months, in the lockdown, we have learned various lessons from the COVID-19."If we wear masks, maintain social distancing and wash hands regularly then people will be 90-95 per cent safer," he said.Jain said on Thursday, India's growth rate of COVID was five per cent and earlier there was a time when the growth rate was 20 per cent. "I believe that the numbers should be seen in terms of the percentage increase."He said the new cases in Delhi are coming from the containment zones as well as from outside the containment zones."We have received various suggestions from the residents of Delhi and based on those we have sent our suggestions to the central government regarding the relaxation of the lockdown. The key suggestions from the people are that every person should wear a mask in public place and social distancing should be maintained all the time. People have also suggested that public transportation should start for example, buses and metros with limited capacity."Regarding the malls, he said people have suggested that in the limited capacity of either 25 per cent or 50 per cent the malls of the city should be opened. They have also suggested that the markets should be opened following either odd-even rules or only three days a week."The Delhi government believes that there should be a balance between the fight against COVID and economic activities. We are fighting against the COVID-19 with full effort, but now we have to start the economic activities, therefore, the measures should be followed. When the lockdown was imposed at that time we were not prepared to fight this pandemic, but now we are prepared to fight this pandemic."Regarding the issue of the migrant labourers, Jain said there are two kinds of people."One is the migrant labourer of Delhi and the second is the migrant labourer of other states who are passing through Delhi. For the migrants, the government has arranged stay and food across Delhi. Any such person you meet can be sent to the nearby shelter of the Delhi government. We are providing lunch and dinner to nearly 10 lakh poor people every day."--IANSnks/dpb
New Delhi, May 8 (IANS) With the number of coronavirus cases in the country climbing to 56,342 on Friday, the Union Health Ministry said that "we have to learn to live with the virus" and that "it is a difficult battle, we need everyone's cooperation".Addressing mediapersons, Lav Agarwal, Joint Secretary at the Health Ministry, said, "We have to learn to live with the virus. We need to introduce certain behavioural changes to implement these (social distancing) practices." The response from the Health Ministry came after a sudden spurt in the number positive cases in the past few days when the tally crossed the 3,000-mark each day. "A total of 3,390 new cases and 103 deaths were reported in the last 24 hours till 8 a.m. on Friday," Agarwal said.Responding to a query over AIIMS Director Randeep Guleria's recent comment that Covid-10 cases will peak in India in June-July, Agarwal said, "If we follow the required dos and don'ts, we may not reach the peak in number of cases and our curve may continue to remain flat."According to the Health Ministry, 16,540 Covid-19 patients, which is about 29.36 per cent of the total cases, have recovered so far, while in the past 24 hours, 1,273 people have been cured.The total number of confirmed cases in India is 56,342. Out of this, 37,916 are active cases while 1,886 people have succumbed to the dreaded virus so far. "In 216 districts, no positive case has been detected. In 42 districts. no new case has been detected in the last 28 days, while 29 districts have not reported any case in the last 21 days," the Health Ministry said.It added that 3.2 per cent of the total active cases are on oxygen support, 4.2 per cent in ICUs and 1.1 per cent on ventilator support.--IANSss/arm
Beijing- In an alarming find, Chinese doctors have recovered live coronavirus in spit and human excreta in samples from recovering COVID-19 patients.The study, published in the journal Annals of Internal Medicine, found that some patients had positive, real-time fluorescence polymerase chain reaction (RT-PCR) test results for SARS-CoV-2 in the sputum or faeces after the pharyngeal swabs became negative.
Pharyngeal swabs are widely used to determine the appropriateness for a patient's discharge from the hospital and/or whether isolation continues to be required.The findings from Beijing Ditan Hospital, Capital Medical University in China raise concerns over whether patients with negative pharyngeal swabs are truly virus-free or if sampling of additional body sites might be needed.For the findings, the clinicians retrospectively identified a convenience sample of patients admitted to Beijing Ditan Hospital, Capital Medical University with a diagnosis of COVID-19 and paired RT-PCR testing of pharyngeal swabs with either sputum or feces.
Among 133 patients admitted with COVID-19 from January 20 to February 27, 2020, the authors identified 22 with an initial or follow-up positive sputum or fecal samples paired with a follow-up negative pharyngeal sample.
RT-PCR positive for SARS-CoV2 of sputum and feces was seen up to 39 and 13 days, respectively, after the obtained pharyngeal samples were negative.The researchers caution that the study was not carried out in a systematic fashion with a sampling of all patients in a protocolized manner, and "it is not known whether this positive sputum or faecal results indicate that the patient could still be infectious to others.''
However, the findings are potentially important because they suggest that more study is needed in this area.The global coronavirus positive cases crossed 7.8 lakh n Tuesday, with nearly 38,000 deaths.As of Tuesday, China reported 82,240 cases, with 3,309 fatalities, according to data compiled by the Center for Systems Science and Engineering (CSSE) at the Washington-based Johns Hopkins University.The US registered 164,274 cases, the highest in the world, while Italy had the largest number of deaths at 11,591.
Amid the social distancing chants during the new coronavirus (COVID-19) pandemic, the great Indian community -- known to be social animals that love to throw parties for every single occasion -- is caged at homes, unable to grasp the new reality around them.
No outings, no late night parties, no birthday dinners and, above all, no movies at cinema halls while dealing with both work and kids at home - this curfew-like atmosphere is unprecedented for many due to a global health crisis.
Experts, however, say that this is just another phase in life that would soon go away and people should live in the moment and enjoy some "me-time".
"Even as physical distancing is encouraged, it's important to stay emotionally connected to loved ones - use social media, cell phones and video calls to keep in touch with friends and family," said Dr Samir Parikh, Director, Department of Mental Health and Behaviour sciences, Fortis Healthcare.
People who are self-isolated at home, they need to maintain a regular routine -- this involves a regular sleep-awake pattern, eating balanced meals and physical exercise.
"Create a list of tasks you want to achieve every day and maintain work-life boundaries by designating a specific time and space to work. Listen to music, watch movies or read a book; use this time meaningfully to engage in activities or hobbies you have wanted to," Parikh told IANS.
Panic is bigger threat that the actual one so stick to reliable sources of information and restrict how much you consume news to a maximum of 1-2 times a day.
"There is a line between caution and panic, one that we must not cross. It's important to check facts and be mindful of the information we ourselves read and forward on social media. Also promote stories of strength and positivity in these times of distress," Parikh emphasized.
According to Dr Manish Jain, Consultant, Psychiatry, BLK Super Speciality Hospital, There is so much panic because people apprehend the worst-case scenario.
"They need to understand facts and clear myths related to COVID-19. More they'll be aware of facts, less there will be panic," said Jain.
The need of the hour is altruism and social responsibility.
"Don't hoard excessive supplies, support others in times of distress, maintain hygiene practices and observe physical distancing, not just for your own safety but that of others as well," Jain told IANS.
With the rising incidence of Covid-19 in the country, it's natural for people to be concerned about their own health and safety as well as of their loved ones.
Till the time you are home, do indoor productive and pleasurable activities such as reading, learn something new such as guitar, socialise with family -- while safety and cleanliness on top of your mind. (IANS)
New York. If you want to live longer, reduce levels of inflammation throughout your body and delay the onset of age-related diseases -- eat less food, say researchers.
According to a study, published in the journal Cell, researchers from the US and China provided the most detailed report of the cellular effects of a calorie-restricted diet in rats.
While the benefits of caloric restriction have long been known, the new results show how this restriction can protect against aging in cellular pathways.
"We already knew that calorie restriction increases life span, but now we've shown all the changes that occur at a single-cell level to cause that," said study senior author Juan Carlos Izpisua Belmonte from the Salk Institute in the US
"This gives us targets that we may eventually be able to act on with drugs to treat aging in humans," Belmonte added.
For the findings, the research team compared rats who ate 30 per cent fewer calories with rats on normal diets.
The diet of animals in the age group of 18-27 months was controlled. (In humans, this would be roughly equivalent to someone following a calorie-restricted diet from the age of 50 to 70.)
The research team isolated and analysed a total of 168,703 cells from 40 cell types in the 56 rats from starting as well as during the conclusion of the diet. The cells came from fat tissues, liver, kidney, aorta, skin, bone marrow, brain and muscle.
In each isolated cell, the researchers used single-cell genetic-sequencing technology to measure the activity levels of genes.
They also looked at the overall composition of cell types within any given tissue. Then, they compared old and young mice on each diet.
Many of the changes that occurred as rats on the normal diet grew older didn't occur in rats on a restricted diet; even in old age, many of the tissues and cells of animals on the diet closely resembled those of young rats.
Overall, 57 per cent of the age-related changes in cell composition seen in the tissues of rats on a normal diet were not present in the rats on the calorie restricted diet, the study said.
"This approach not only told us the effect of calorie restriction on these cell types, but also provided the most complete and detailed study of what happens at a single-cell level during aging," said study researcher Guang-Hui Liu from Chinese Academy of Sciences in China.
According to the study, some of the cells and genes most affected by the diet related to immunity, inflammation and lipid metabolism.
The number of immune cells in nearly every tissue studied dramatically increased as control rats aged but was not affected by age in rats with restricted calories.
In brown adipose tissue--one type of fat tissue--a calorie-restricted diet reverted the expression levels of many anti-inflammatory genes to those seen in young animals, the research said (IANS)
