Walking keeps death away

Association of Daily Step Count and Step Intensity With Mortality Among US Adults

JAMA. 2020; 323(12):1151-1160.

Question  What are the associations between daily step counts and step intensity with mortality among US adults?

Findings  In this observational study that included 4840 participants, a greater number of steps per day was significantly associated with lower all-cause mortality (adjusted hazard ratio for 8000 steps/d vs 4000 steps/d, 0.49). There was no significant association between step intensity and all-cause mortality after adjusting for the total number of steps per day.

Meaning  Greater numbers of steps per day were associated with lower risk of all-cause mortality.

At this time of year, plans are always being made to improve our lives in the coming year. This research provides us with an opportunity to make an important and meaningful choice for our well-being. It’s free and affordable for everyone. It involves walking, an activity that many of us do on an extremely limited basis. It does not matter the speed, to obtain benefits it is enough to move with our pace, however, it is necessary to do 8,000 a day to obtain this positive result that will make us live better and longer.

The deadly risk of the sedentary life

Strong evidence shows that physical inactivity increases the risk of many adverse health conditions, including the world’s major non-communicable diseases (NCDs) of coronary heart disease (CHD), type 2 diabetes, and breast and colon cancers, and shortens life expectancy. Because much of the world’s population is inactive, this presents a major public health problem.

Worldwide, we estimate that physical inactivity is responsible for between 6% and 10% of the major NCDs of CHD, type 2 diabetes, and breast and colon cancers. And, this unhealthy behaviour is responsible for 9% of premature mortality, or >5.3 of the 57 million deaths in 2008. By eliminating physical inactivity, life expectancy of the world’s population may be expected to increase by 0.68 years. This makes inactivity comparable to the established risk factors of smoking and obesity, discussed below. It is important to interpret the added years of life correctly: they appear modest because they represent gains in the whole population (comprising inactive and active persons), not among inactive persons who become active. Because all the gain accrues to those who move from inactive to active, the increase in life expectancy among the inactive alone is greater. For perspective, other research conducted in the United States estimated that inactive persons would gain 1.3–3.7 added years from age 50 by becoming active. And, among East Asians, life expectancy from age 30 among the active was 2.6–4.2 years greater, compared with inactive persons.”

  • Noncommunicable diseases (NCDs) kill 41 million people each year, equivalent to 71% of all deaths globally.
  • Each year, 15 million people die from a NCD between the ages of 30 and 69 years; over 85% of these “premature” deaths occur in low- and middle-income countries.
  • Cardiovascular diseases account for most NCD deaths, or 17.9 million people annually, followed by cancers (9.0 million), respiratory diseases (3.9million), and diabetes (1.6 million).
  • These 4 groups of diseases account for over 80% of all premature NCD deaths.
  • Tobacco use, physical inactivity, the harmful use of alcohol and unhealthy diets all increase the risk of dying from a NCD.
  • Detection, screening and treatment of NCDs, as well as palliative care, are key components of the response to NCDs.

Modifiable behavioural risk factors

Modifiable behaviours, such as tobacco use, physical inactivity, unhealthy diet and the harmful use of alcohol, all increase the risk of NCDs.

  • Tobacco accounts for over 7.2 million deaths every year (including from the effects of exposure to second-hand smoke), and is projected to increase markedly over the coming years.
  • 4.1 million annual deaths have been attributed to excess salt/sodium intake.
  • More than half of the 3.3 million annual deaths attributable to alcohol use are from NCDs, including cancer.
  • 1.6 million deaths annually can be attributed to insufficient physical activity.”

Is sport for all a lost war?

“Over 6.3 million adults aged 40 to 60 do not achieve 10 minutes of continuous brisk walking over the course of a month and are missing out on important health benefits, according to the Public Health England (PHE10 minutes brisk walking recommendations: evidence summary.

The findings also reveal how lifestyles have changed over time, showing that people in the UK are 20% less active now than they were in the 1960s and on average walk 15 miles less a year than 2 decades ago. The sedentary nature of modern, busy lives makes it difficult for many to find the time for enough exercise to benefit their health.

PHE’s new One You physical activity campaign is encouraging adults to build 10 minutes continuous brisk walking into their day as a simple way to improve their health. This is particularly aimed at those who have an inactive or low activity lifestyle and may find incorporating activity into their day challenging. The ‘Active 10’ app has been developed to show how much brisk walking a person is doing each day and how to incorporate more of it into their lifestyles.

Taking at least 1 brisk 10 minute walk a day has been shown to reduce the risk of early death by 15%. A 10 minute walk can contribute to meeting the CMO’s physical activity guidance of 150 minutes of moderate to vigorous exercise each week. This can lead to health benefits including a lowered risk of type 2 diabetes (by 40%), cardiovascular disease (by 35%), dementia (by 30%) and some cancers (by 20%).

The severity of the current physical inactivity epidemic amongst adults contributes to 1 in 6 deaths in the UK and is costing the NHS over £0.9 billion per year.”

20-minutes walk to avoid obesity risk

Lack of exercise is twice as likely to determine the obesity beginning and a daily break of 20-minute walk permits to avoid the premature death.

The effects of obesity and exercise have been studied on 334,161 men and women for 12 years period . Although the impact of exercise was greatest among people of a normal weight, even those with a high body mass index (BMI) levels saw a benefit. Lack of exercise was thought to have caused almost 700,000 deaths across Europe in 2008.

Study leader Prof Ulf Ekelund – Medical Research Council (MRC) epidemiology unit at Cambridge University, said: “This is a simple message: just a small amount of physical activity each day could have substantial health benefits for people who are physically inactive. Although we found that just 20 minutes would make a difference, we should really be looking to do more than this – physical activity has many proven health benefits and should be an important part of our daily life.”

Participants in the research, who had an average age of about 50, were recruited to the European Prospective Investigation into Cancer (Epic) study conducted across 10 European countries, including the UK. All had their height, weight and waist sizes measured and provided self-assessments of physical activity levels.

Just under a quarter (22.7%) were categorised as inactive, working in sedentary jobs without engaging in any recreational exercise.

The findings, which are published in the American Journal of Clinical Nutrition, say the greatest reductions in the risk of premature death were seen when comparing moderately active groups with those who were completely inactive.

Using the most recent available public data, the researchers calculated that 337,000 of the 9.2m deaths that occurred in Europe in 2008 could be attributed to obesity, but physical inactivity was thought to be responsible for almost double this number – 676,000 deaths.

Co-author Prof Nick Wareham, director of the MRC epidemiology unit, said: “Helping people to lose weight can be a real challenge and, whilst we should continue to aim at reducing population levels of obesity, public health interventions that encourage people to make small but achievable changes in physical activity can have significant health benefits and may be easier to achieve and maintain.”

June Davison, senior cardiac nurse at the British Heart Foundation, said: “The results of this study are a clear reminder that being regularly physically active can reduce the risk of dying from coronary heart disease.

“The research suggests that just a modest increase in physical activity can have health benefits. Adults should aim to do at least 150 minutes of moderate intensity activity a week, carrying it out in sessions of 10 minutes or more.

“Whether it’s going for a walk, taking a bike ride or using the stairs instead of the lift, keeping active every day will help reduce the risk of developing coronary heart disease.”

US: 87% parents worried about injuries in sports

In US “Youth sports are becoming increasingly competitive, and most parents believe children are suffering.

According to a new national poll released by the espnW: Women + Sports Summit this weekend, two-thirds of parents think there is “too much emphasis on winning over having fun,” and 87% of parents said they were worried about the risk of injury in sports.

Parents are most concerned about concussions on the high school football field, which increasingly have been in the headlines lately (including on TIME’s cover). Just in the past week, three high school football players in Alabama, North Carolina and New York have died, possibly due to football injuries.

Parental concerns could explain the drop in participation in youth sports in the last several years. In 2008, 44.5% of children ages 6-12 participated in some type of sports organization. Only 40% of children did so in 2013, according to the Sports & Fitness Industry Association. Football, basketball, baseball and soccer have all seen double-digit declines in participation (though lacrosse and hockey have not).”

I due alpinisti sul Bianco sono morti

Purtroppo sono morti i due alpinisti sul Bianco e non sapremo mai il perchè. La montagna è così fatta, non lascia scampo quando si sbaglia. L’errore, se c’è stato, è stato di fidarsi troppo delle proprie abilità e partire per un’impresa già difficile con il bel tempo, sapendo che sarebbe peggiorato e di molto. Questo è successo ed è quasi impossibile resistere a quell’altezza con quella temperatura. In montagna gli errori si pagano spesso con la vita o con gravi menomazioni; l’eccesso di sicurezza è spesso una causa d’incidenti, si pensa di essere immortali e poi ci viene dimostrato il contrario. L’alpinismo non è uno sport ma quanto è accaduto fa certo parte del capitolo: rendimento e preparazione psicologica. Si potrebbe dire in modo cinico: pensavamo di essere così bravi da ingannare la montagna.
