Taking vitamin D supplements does not reduce the risk of asthma attacks in children or adults, according to an updated Cochrane review.

These findings are in contrast to a previous Cochrane review that indicated a reduction in asthma attacks in people taking vitamin D. However, the review found no harm in taking vitamin D and it did not examine other possible health benefits.

The review was carried out by researchers from Queen Mary University of London and the University of Edinburgh. Researcher Adrian Martineau, Clinical Professor of Respiratory Infection and Immunity at Queen Mary University of London, said: “Vitamin D deficiency has been linked to an increased risk of severe asthma attacks and our previous Cochrane review, published in 2016, found that vitamin D reduced the risk of asthma attacks. However, more studies have been published since then and when we included the extra data in our updated review, the overall results changed. We found that vitamin D supplements had no effect on risk of asthma attacks or on control of asthma symptoms compared with a placebo.”

Professor Martineau and his colleagues analysed the results of 20 randomised controlled trials – the gold-standard for medical research – including data on 1,155 children and 1,070 adults with asthma. This compares to nine trials involving a total of 1,093 people whose data contributed to the previous review. The majority of patients in the trials had mild to moderate asthma.

When they compared patients who were assigned to take a vitamin D supplement with patients who were assigned to take a placebo (dummy medication), the researchers found no statistically significant difference in the number of people who experienced an asthma attack requiring treatment with a course of steroid tablets.

The review did not find any effect of taking vitamin D on asthma control even when people were vitamin D-deficient when they joined the studies, or with different doses of the supplement, or in people of different ages.

Professor Martineau said: “In contrast to our previous Cochrane review on this topic, this updated review does not find that vitamin D offers protection against asthma attacks or improves control of asthma symptoms. However, the trials we looked at did not include many people with severe asthma or people with very low levels of vitamin D in their blood, so these are areas where more research is still needed."

Anne Williamson, the first author on the study who is also from Queen Mary University of London, commented: “We can’t be certain why this updated review has given a different result to our original study from 2016. It could be that people with asthma may be getting better treatment than previously. Or it could be that, in general, rates of vitamin D deficiency have decreased over time, due to increasing intake of supplements or fortified foods. Either of these factors could obscure potential benefits from taking vitamin D supplements. Regardless of the reason, these most recent findings are likely to be correct for people living with asthma today.

This also highlights why it’s vital to update reviews when more research is published.”

Today’s review includes data from 20 clinical trials, compared with nine in the 2016 review, and children with asthma are better represented than previously. The review team say they have also applied stricter criteria on which studies would be included, compared to some other reviews. For example, they excluded studies that did not compare vitamin D with a placebo and those that did not monitor patients for at least 12 weeks.

Most of the trials included in the review involved patients taking cholecalciferol, which is the typical form of vitamin D supplement. One trial that used calcidiol, which is a compound that the body can make from vitamin D, reported an improvement in asthma control in patients taking this supplement. The reviewers say further research is needed to confirm whether this form of vitamin D has benefits for people with asthma.

Measures to eliminate hazards around the home, such as reducing clutter, adding railings to stairs and improving poor lighting, can reduce the risk of falls for older people by around a quarter, according to a Cochrane review recently published.

The review did not find any compelling evidence for other measures to reduce falls, such as making sure older people have the correct prescription glasses, special footwear, or education on avoiding falls.

It also found that decluttering and reducing hazards had the most benefit for older people who are at risk of falls, for example because they have recently had a fall and been hospitalised or need support with daily activities such as dressing or using stairs.

Nearly one third of people aged 65 years and older fall each year. Most falls occur in the home.

Lindy Clemson, Professor Emeritus at the University of Sydney, Australia was lead author of the review. She said: “Falls are very common among older people. They can cause serious injury or even death, but they are preventable. In this review we wanted to examine which measures could have the biggest impact on reducing falls among older people living at home.”

Professor Clemson and her colleagues analysed the results of 22 studies including data on 8,463 older people living in the community.

They found that taking measures to reduce fall hazards around the home lowers the overall rate of falls by 26%. This typically includes an assessment of fall hazards in and around the home and recommendations for lowering the risk, for instance by removing clutter and adding handrails and non-slip strips to steps. These measures have the biggest effect (38% fewer falls) for people who are at a higher risk of falls. Based on their analyses, the reviewers found that if 1,000 people who had previously had a fall followed these measures for about a year, the total number of falls would come down from 1,847 to 1,145.

Professor Clemson said: “Having had a fall or starting to need help with everyday activities are markers of underlying risk factors, such as being unsteady on your feet, having poor judgement or weak muscles. These risk factors make negotiating the environment more challenging and increase the risk of a trip or slip in some situations.

The research shows that, for those at risk of falls, being aware of fall hazards in and around the home, removing hazards and adapting with safe behaviours can significantly reduce the risk of falling. It appears that interventions to reduce fall hazards around the home need certain elements of assessment and support to work, not just a short check list of things to tick off. So, while everyone can take more care about their home environment and should do exercise for balance and lower limb strength, professional support from an occupational therapist is an important intervention for many people living at home."

“We encourage all people, as they age, to reduce fall hazards. These are often simple things like removing or changing slippery floor mats, improving lighting on stairs or de-cluttering the home. It seems this is not always ‘common sense’. People tend not to notice clutter around their home or realise that climbing ladders the way they always have is potentially a fall risk, particularly if their mobility or balance is not as it used to be.”

While the review showed fewer falls with hazard reduction, there was not enough data from the studies to determine if there were fewer admissions to hospital due to a fall. The authors found limited evidence for the other approaches to prevent falls that they examined – assistive technologies and education. They also found there was a lack of research on the impact on fall reduction of providing equipment or modifications to help older people carry out daily activities, such as showering or as cooking a meal.

Professor Clemson added: “Preventing falls is a really important way of helping people to remain healthy and independent as they grow older, and our review also highlights the need for more research in this area.”

Cochrane is delighted to announce the availability of RevMan Web, its popular, web-based systematic-review production software, to the wider academic community beyond Cochrane – to support evidence synthesis development and evidence-based medicine education. Cochrane expects interest in use of the tool from those in universities and medical schools, and many other research sectors.

RevMan Web facilitates the creation of meta-analyses, forest plots, risk-of-bias tables, and other systematic review elements. It is acknowledged to be easy-to-use – and is also widely used in learning or training about systematic review production.

Cochrane is making RevMan Web available for use by institutions or individuals for their own systematic review development work. The product is presented on a Software-as-a-Service basis: Cochrane offers a hosted service, comprising the software and cloud storage of all review data uploaded. 

Laura Ingle, Cochrane’s Director of Publishing and Technology, says this is a hugely positive step forward: “Cochrane’s investment and development of RevMan Web has allowed the preparing and maintaining of Cochrane Reviews to reach our high standards and methodologies – making Cochrane reviews the gold standard in health evidence. Cochrane is committed to making RevMan Web the platform of choice for all systematic review production, and now we are enabling access to RevMan Web for the wider review community at a reasonable and affordable cost.

"In addition to reviews of studies of the effects of healthcare interventions, you can use RevMan Web to write reviews that synthesize qualitative evidence, reviews of prognosis studies, reviews of studies of methodology, diagnostic test accuracy reviews, and overviews of reviews. RevMan Web is easy to use, is a safe and central place to manage all reviews, and allows collaboration across people to work on the same project. With its included learning and training materials, it also makes it a great training tool for teaching systematic review techniques. 

"Cochrane authors have been using RevMan for 5 years and we are excited to offer this systematic review and meta-analysis software to individual researchers, those working on reviews together, and to those looking for licences for their university. It’s a great tool for those generating one-off meta-analyses and forest plots or conducting their own systematic reviews.”

Free access is available in Research4Life low and middle-income countries and to Cochrane Review authors working on Cochrane Reviews. Cochrane authors working on non-Cochrane reviews, Cochrane Members, students,  and academics are eligible for a discounted rate.

Dr Jenny McSharry, Health Psychologist and lecturer in the School of Psychology at the University of Galway, explains what systematic reviews are and why they are a particularly trustworthy source of health evidence. 

Dr Jenny Mc Sharry was supported by an Evidence Synthesis Ireland Writing Mentorship (Grant code ESI-2021-001) and this blog post was originally posted on Evidently Cochrane.

When we are diagnosed with a new condition, experience a worrying symptom or need to make a health decision for ourselves or our loved ones, it can be hard to know where to turn. How often have we found ourselves unable to sleep, alone at 3AM, searching online for answers to questions we never thought we would have to ask?  In times of anxiety and uncertainty, how can we know what health evidence to trust when we need it most?

When looking for reliable information to help with health decisions, reviews of evidence, in particular systematic reviews, can be a good place to start.

Systematic reviews of multiple studies can be useful for health decisions

Reviews that bring together and summarise the existing evidence are more reliable than one research study, or one person’s opinion or experience. Lots of things can affect the findings of a research study and we can have more confidence in reviews that bring together lots of studies. There is more information on why Personal experiences or anecdotes (stories) are an unreliable basis for assessing the effects of most treatments on the Evidently Cochrane blog.

Systematic reviews are seen as the gold-standard of research evidence. A systematic review is a type of review that tries to find, assess, and summarise all the evidence that meets pre-specified criteria to answer a specific question. Researchers who complete systematic reviews follow a number of key steps to make their findings more trustworthy.

Systematic reviews summarise evidence related to a specific question

Systematic reviews look for evidence that might help answer a specific question, and clearly outline this question from the start. For example, a systematic review Antihistamines for motion sickness was done to find out if  medicines used for allergy symptoms (antihistamines) work and are safe in preventing travel (motion) sickness. The review summarises evidence on how antihistamines compare with dummy treatment (placebo), no treatment, and other medicines. This review is useful if you want to find evidence about medicines for travel sickness, but not if you want to know if you should avoid reading or drink ginger tea while travelling. When a review clearly states its focus, it helps us judge whether it is relevant and useful to us.

Systematic reviews aim to find all studies that meet certain criteria

Systematic reviews researchers try to find and include all studies relevant to a specific question. This is important, as we want all relevant information to be available to us when making a health decision. When using evidence from a review to decide if we should start a new treatment for example, we want to be sure that studies that found benefits, studies that found harms, and studies that found little or no difference, are just as likely to have been included.

Systematic review researchers try to find all relevant studies by clearly outlining the sources they will search, and by making a list of the criteria they will use to decide if studies should be included. For example, in our review Video calls for reducing social isolation and loneliness in older people, we wanted to find out if older people who used video calls to keep in touch with family and friends feel less lonely than those who did not. For this review, we needed to decide on what we meant by older adults, as the findings might be different for people aged 65 and older, or people aged 70 and older. For this review, we decided to include studies of people aged 65 and older and made it clear when reporting the findings that this was the group we had focused on.

Systematic review researchers clearly state the methods they will use to identify studies before starting the review. Other researchers should be able to use these methods and find the same set of studies.

Systematic reviews assess and report on the quality of evidence

When reading reviews of evidence, it is important to know how many relevant studies there are, but also to know if the studies are of good quality. Even if a number of studies find that a treatment is beneficial, we may not want to choose this treatment if we find out that the number of people included in the studies was very small, or that the way in which people were identified to take part in the studies was not clear. For a systematic review, researchers assess if the methods used in the included studies were appropriate. Researchers then make a judgement on the level of certainty we can have in the overall evidence, based on whether the included studies were done well or not.

Finding relevant systematic reviews: Where to look?

When it comes to trustworthiness, not all information we find is equal, and it is good to know that systematic reviews can be helpful in making health decisions. However, when feeling anxious about a health condition or symptom, or when trying to make an urgent health decision, it can be hard to know how to find relevant systematic reviews.

Cochrane is an independent global organisation that aims to provide high-quality evidence to inform decisions about health and care. Cochrane systematic reviews are published online in the Cochrane Library. The Cochrane Library is free to access for people in the UK and Ireland (and in many other countries). You can search by topic, and the reviews all have a Plain Language Summary. The blogs here on Evidently Cochrane aim to make health evidence easy to understand and use by providing summaries of Cochrane Reviews in context, often alongside patients’ and health professionals’ experiences. Evidently Cochrane includes an A-Z list of topics to make it easier to search for relevant evidence, and can be a good place to start when supporting family and friends or making choices about our own health.

What else can you do to work out if health information is trustworthy?

If you are interested in finding out more about health information and what we can trust, the blog, Making health decisions: things that can help, looks at some key things to consider to help us to make the right decision and to reduce the risk of regretting our choices later on. The blog also reminds us that summaries of research evidence are just one part of how we make health decisions, and our own preferences and values and the views of healthcare professionals are also very important. The blog includes lots of resources to help you think critically about health information and to support your decision-making.

Family-centred care is a way of providing care that focuses on the needs of children while providing planned care around the whole family unit. A new Cochrane review published recently found there was a small improvement in the overall health and well-being of Indigenous children and their families when they participated in family-centred care programmes at a primary healthcare service.

‘Family centred-care is not new,’ says lead author Dr Natalie Strobel, Senior Research Fellow at Edith Cowan University’s Centre for Improving Health Services for Aboriginal and Torres Strait Islander Children and Families. ‘Aboriginal Medical Services have been doing this for years. For example, they don’t just immunise babies, they talk to mums, aunts, uncles, grandparents and everybody that’s part of that family unit – trying to ensure that everybody's getting care. That’s both health and social care, so it might be making sure there’s appropriate housing, referrals to services that they needed or for other types of support.’

‘We know that primary healthcare, particularly Indigenous-led services, are well placed to deliver services that reflect the needs of Indigenous children and their families. Of our author team of nine, four are Aboriginal and have worked in health services as nurses and midwives for a long time. Families want primary healthcare services that both support them and recognise Indigenous ways of knowing and doing business. This can be delivered through environmental, communication, educational, counselling, and family support approaches.’

A key finding of this new review was that family-centred care delivered by primary healthcare services may improve the overall health and well-being of children and their families, however, due to a range of factors, the evidence was rated as very low certainty. There was also evidence to suggest that families who participated in family-centred care increased their parenting knowledge and awareness to a small degree. However, for all other outcomes it was unclear whether family-centred care improves specific child health and well-being outcomes. Ultimately more high quality trials are needed to generate evidence to determine whether family-centred care improves the health and well-being of Indigenous children.

‘We consider family-centred care to be really promising, but we’re not confident in the evidence for a range of reasons, which are quite complex,’ Natalie says. ‘For example, people in the studies were aware of what intervention they were getting, many people did not come back to report their results, and not all the studies reported the information we were interested in. Also, some of the issues around low quality of evidence are really hard for communities that are doing this type of work to get around.’

‘For instance, in the United States you're delivering the intervention on a reservation and there's not a huge number of people to do this work. Often the person who delivers the intervention also collects the data. We know that's got a significant level of bias involved in it, but it's also very pragmatic, that's what happens and how it has to work because there's not enough people to complete the project. This highlights the challenges of conducting high quality studies, and underscores the need to build capacity and support people in communities.’

‘I think with the advent of this type of research, it will give people an idea of what's going on in the field so that they know where potentially they could identify and collect better evidence to add to this emerging evidence base. Ultimately it is quite a tricky space, and realistically when you are trying to do things that are good for your community, you have to make allowances and be pragmatic about how research is delivered.’

‘Overall, this was a huge and complex review that was really challenging to deliver but we’re so pleased we did,’ Natalie says. ‘I really have to hand it to the team though. It was their sheer persistence that delivered this review, and the reward now for us is having this really high quality piece of work that people from health services can use to show how effective their programs are. We wanted to support local services to advocate for themselves and now they can use this information as they need – either to show where they might need to make changes or to demonstrate that what they're doing is effective and benefits children, families and communities. They are really making a difference.’

Physical exercise can help to improve the severity of movement-related symptoms and the quality of life in people with Parkinson’s Disease. Findings from the first Cochrane review of the available evidence found that any type of structured exercise is better than none.

The Cochrane Movement Disorders review looked at 156 randomised controlled trials comparing physical exercise with no physical exercise or with different types of exercise, and it included a total of 7,939 people from around the world, making it the largest and most comprehensive systematic review to study the effects of physical exercise in people with Parkinson’s Disease. 

The review from Cochrane, a collaboration of independent, international experts, was led by Dr Elke Kalbe, Professor of Medical Psychology at the University of Cologne, Germany. It found that physical exercise ranging from dance, water-based exercise, strength and resistance exercise and endurance exercise, to tai chi, yoga and physiotherapy, made mild to large improvements to the severity of movement-related (‘motor’) symptoms and quality of life. 

“Parkinson’s Disease is a progressive disorder of the nervous system that mostly affects people over 60,” said Professor Kalbe. “Symptoms begin gradually and include movement problems such as trembling, stiffness, slowness of movement and balance, and lack of coordination. People can also have emotional and mood problems, fatigue, sleep problems and cognitive difficulties. Parkinson’s Disease cannot be cured, but the symptoms can be relieved, and physiotherapy or other forms of exercise may help too. Until now it has been unclear whether some types of exercise work better than others. We wanted to find out what exercise works best to improve movement and quality of life.”

The average age of the participants in the studies included in the review was between 60 and 74 years. Most had mild to moderate disease and no major impairment of their thinking processes. The review found that most types of exercise worked well for the participants compared to no physical exercise.

The first author of the review, Mr Moritz Ernst, is a member of Cochrane Haematology and deputy head of the working group on Evidence-based Medicine, which is led by co-author of the study, Professor Nicole Skoetz, at University Hospital Cologne. He said: “We observed clinically meaningful improvements in the severity of motor symptoms for most types of exercise. These included dancing, training to improve gait, balance and movement, multi-exercise training, and mind-body training.  

“We saw similar benefits in the severity of motor symptoms for water-based training, strength and resistance training, and endurance training, but the estimates of improvement were rather imprecise, meaning that we are not as confident in saying that these improvements are clinically meaningful.

“For the effects on quality of life, we observed clinically meaningful beneficial effects for water-based training, and effects that are probably clinically meaningful for several types of exercise, such as endurance training, mind-body training, training to improve gait, balance and movement and multi-exercise training. Again, these estimates were rather imprecise.”

The certainty in the estimates for the effects on symptoms from different forms of exercise varied because some studies were very small, and not all provided information on the severity of motor symptoms and quality of life for all the participants. However, the authors say that their review highlights that most types of exercise produced meaningful improvements, and they found little evidence of much difference between different exercises.

Prof. Kalbe said: “We think that our results are good news because they indicate that people with Parkinson’s Disease can benefit from various structured exercise programmes to improve the severity of motor symptoms and quality of life. Our review highlights the importance of physical exercise in general, while the exact exercise type may be secondary. Therefore, the personal preferences of people with Parkinson’s Disease should be given special consideration to help motivate them to adhere to an exercise programme. Any exercise counts! 

“It is important to point out that our conclusions do not rule out that certain motor symptoms may be treated most effectively by programmes, such as physiotherapy, that are designed specifically for people with Parkinson’s disease.”

Mr Ernst concluded: “Although our results are quite promising for people with Parkinson’s Disease, the certainty in the evidence on the efficacy of different exercise types and on potential differences between them, was usually limited. This was also because most studies had a very small sample size. Therefore, although there is already a large amount of research in this field, we would encourage researchers to conduct larger studies with clearly defined samples, as this would help to draw conclusions with more confidence. In addition, it would be admirable to see studies that focus on people with more advanced disease and thinking impairment, so that we could find out if physical exercise could also be beneficial for these people.”

Cochrane is named in honour of Archie Cochrane, a British medical researcher who contributed greatly to the development of epidemiology as a science. 

Archie Cochrane is best known for his influential book, Effectiveness and Efficiency: Random Reflections on Health Services, published in 1972. The principles he set out in it so clearly were straightforward: he suggested that, because resources would always be limited, they should be used to provide equitably those forms of health care which had been shown in properly designed evaluations to be effective. In particular, he stressed the importance of using evidence from randomized controlled trials (RCTs) because these were likely to provide much more reliable information than other sources of evidence. Cochrane's simple propositions were soon widely recognised as seminally important - by lay people as well as by health professionals.

How can we have a rational health service if we don’t know which of the things being done in it are useful and which are useless or possibly even harmful? — Archie Cochrane

In 1979 he wrote, "It is surely a great criticism of our profession that we have not organised a critical summary, by specialty or subspecialty, adapted periodically, of all relevant randomised controlled trials." His challenge led to the establishment during the 1980s of an international collaboration to develop the Oxford Database of Perinatal Trials.

In 1987, the year before Cochrane died, he referred to a systematic review of RCTs of care during pregnancy and childbirth as "a real milestone in the history of randomized trials and in the evaluation of care", and suggested that other specialties should copy the methods used. His encouragement, and the endorsement of his views by others, led to the opening of the first Cochrane Centre (in Oxford, UK) in 1992 and the founding of  Cochrane in 1993.
