School sex education often negative, heterosexist, and out of touch

12 Sep, 16 | by Emma Gray

And taught by poorly trained, embarrassed teachers, say young people

School sex education is often negative, heterosexist, and out of touch, and taught by poorly trained, embarrassed teachers, finds a synthesis of the views and experiences of young people in different countries, published in the online journal BMJ Open.

Schools’ failure to acknowledge that sex education is a special subject with unique challenges is doing a huge disservice to young people, and missing a key opportunity to safeguard and improve their sexual health, conclude the researchers.

They base their findings on 55 qualitative studies which explored the views and experiences of young people who had been taught sex and relationship education (SRE) in school based programmes in the UK, Ireland, USA, Australia, New Zealand, Canada, Japan, Iran, Brazil and Sweden between 1990 and 2015.

Most of the participants were aged between 12 and 18.

The researchers synthesised the feedback and found that despite the wide geographical reach of the studies, young people’s views were remarkably consistent.

Two overarching themes emerged to explain most of the data. The first of these was that schools have failed to recognise the distinctive and challenging nature of SRE, for the most part preferring to approach it in exactly the same way as other subjects, say the researchers.

Yet the feedback indicated there are distinct challenges when teaching SRE: in mixed sex classes young men feared humiliation if they weren’t sexually experienced and said they were often disruptive to mask their anxieties; their female class mates felt harassed and judged by them.

Young people also criticised the overly ‘scientific’ approach to sex, which ignored pleasure and desire, and they felt that sex was often presented as a ‘problem’ to be managed. Stereotyping was also common, with women depicted as passive, men as predatory, and little or no discussion of gay, bisexual, or transgender sex.

The second principal theme was that schools seem to find it difficult to accept that some of their students are sexually active, leading to content that is out of touch with the reality of many young people’s lives and a consequent failure to discuss issues that are relevant to them, say the researchers.

This was evident in what young people perceived as an emphasis on abstinence; moralising; and a failure to acknowledge the full range of sexual activities they engaged in.  Sex education was delivered too late, some students felt.

But it also manifest in a failure to deliver helpful and practical information, such as the availability of community health services, what to do if they got pregnant, the pros and cons of different methods of contraception, or the emotions that might accompany sexual relationships.

Young people also disliked having their teachers deliver SRE, not only because they felt teachers were poorly trained and too embarrassed, but also because of the potential for this arrangement to disrupt teacher-pupil relationships and breach boundaries.

The researchers point out that despite its low status and variable content and quality, school based SRE is seen as vital by policy makers for protecting young people from ill health, unwanted pregnancies, sexual abuse and exploitation.

And the evidence suggests that young people themselves want SRE to be taught in schools, using an approach that is ‘sex positive’—one that aims for young people to enjoy their sexuality in a way that is safe, consensual, and healthy.

They conclude: “Schools should acknowledge that sex is a special subject with unique challenges, as well as the fact and range of young people’s sexual activity, otherwise [they] will continue to disengage from SRE, and opportunities for safeguarding and improving their sexual health will be reduced.”

The August most read list contains papers with a number of different study designs, on a number of different topics. Returning to the top spot this month is a systematic review on the lack of an association or an inverse association between low-density-lipoprotein cholesterol and mortality in the elderly, by Ravnskov et al. At numbers three and six respectively, we have Quigley et al with a cross-sectional study examining the association between breast feeding outcomes and place of birth, and Tabassum et al with a study on the association of volunteering with mental well-being which also received a press release. Levett et al come in at number eight with randomised controlled trial which concludes that an antenatal integrative medicine education programme in addition to usual care significantly reduced epidural use and caesarean section in nulliparous women. Finally, at number ten is an experimental study by Eleftheriou et al looking at the influence of attractiveness on the condom use intentions of heterosexual men.

Complimentary therapies, well-being and consultants as victims of bullying: Most read articles in July.

11 Aug, 16 | by Fay Pearson

 Tired Doc

July’s top 10 most read papers sees two studies taking into account doctors’ points of view. The first, by Bourne et al., takes a closer look at look at which aspects of the complaints process they find the most stressful. The second, by Shabazz et al., uses a survey of Royal College of Obstetricians and Gynaecologists to explore how significant numbers of consultants in the UK are victims of bullying.

We also have a study by Linton et al., that systematically reviews self-report measures for assessing well-being, and a randomised controlled trial by Levett et al., that concludes that the use of complementary therapies during birth can significantly reduce usage of epidurals and cesarean sections.

Volunteering in middle age and senior years linked to enhanced mental health

8 Aug, 16 | by Emma Gray

No positive association seen before age of 40, suggesting link varies across life course

Volunteering in middle and older age is linked to good mental health/emotional wellbeing, finds a large study of British adults, published in the online journal BMJ Open.

But no such association was seen before the age of 40, suggesting that the link may be stronger at certain points of the life course, say the researchers.

Previous research has shown that volunteering in older age is associated with better mental and physical health, but it’s unclear whether this extends to other age groups.

The researchers therefore mined responses to the British Household Panel Survey (BHPS), involving a representative sample of adults living in 5000 households in Great Britain.

The BHPS ran every year from 1991 until 2008 before being incorporated into a much larger survey.  It included a wide range of questions on leisure time activities, which covered the frequency of formal volunteering—from at least once a week through to once a year or less, or never.

The BHPS also included a validated proxy for mental health/emotional wellbeing known as the GHQ-12.

The researchers gathered 66,343 responses for 1996, 1998, 2000, 2002, 2004, 2006 and 2008.

Around one in five respondents (21%) said they had volunteered. Women tended to volunteer more than men, and while almost a quarter of those aged 60 to 74 said they volunteered, this proportion dropped to 17% among the youngest age group.

GHQ-12 scores were better (lower) among those who volunteered than among those who had never done so—10.7 vs 11.4—across the entire sample, irrespective of age.

The average GHQ score was the best (lowest) among those who were frequent volunteers and worst (highest) among those who never volunteered.

When age was factored in, the positive association between volunteering and good mental health/emotional wellbeing became apparent at around the age of 40 and continued up into old age (80+).

Those who had never volunteered had lower levels of emotional wellbeing, starting at midlife and continuing into old age, compared with those who did volunteer.

The findings held true even after taking account of a range of potentially influential factors, including marital status, educational attainment, social class, and state of health.

By way of an explanation for the findings, the researchers speculate that volunteering at younger ages may just be viewed as another obligation, while social roles and family connections in early middle age may spur people to become involved in community activities, such as in their child’s school.

This is an observational study so no firm conclusions can be drawn about cause and effect, added to which the researchers were not able to gauge the extent of ‘informal’ volunteering, such as helping out neighbours, so couldn’t capture the full spectrum of voluntary activities.

But they nevertheless suggest that the findings show that volunteering may be more meaningful at certain points of the life course, and they call for greater efforts to involve middle aged to older people in some sort of volunteering.

“Volunteering might provide those groups with greater opportunities for beneficial activities and social contacts, which in turn may have protective effects on health status…With the ageing of the population, it is imperative to develop effective health promotion for this last third of life, so that those living longer are healthier,” they write.

Previous research indicates that people who volunteer are likely to have more resources, a larger social network, and more power and prestige, all of which have knock-on effects on physical and mental health, they point out.

“Volunteering may also provide a sense of purpose, particularly for those people who have lost their earnings, because regular volunteering helps maintain social networks, which are especially important for older people who are often socially isolated,” they add.

Top 10 Most Read: Cholesterol and mortality in the elderly, chronic pain in the UK and smokers’ quitting attempts

8 Jul, 16 | by Ed Sucksmith

cigarettes-1221102_960_720

Several new entries make it into our top 10 Most Read list this month. In first place is a systematic review on the associations between low-density-lipoprotein cholesterol and mortality in the elderly. Further down the list is an analysis of Italian medical societies’ websites to examine conflicts of interest between professional medical societies and industry. Other new entries this month include an investigation into the relationship between air pollution and child and adolescent mental health by researchers from Umeå University in Sweden. Using a cohort of over half a million individuals under 18 years of age, the authors found that neighbourhood air pollution concentration is associated with dispensed medications for certain psychiatric disorders. At number 6 is a systematic review and meta-analysis of the prevalence of chronic pain in the UK. The authors conclude that chronic pain affects between one-third and one-half of the population of the UK, corresponding to just under 28 million adults. Lastly, making it in at number 9 is a study by Chaiton and colleagues on smokers’ quitting behaviour. The authors found that it may take as much as 30 or more attempts before a smoker quits successfully.

Third to half of UK population lives with chronic pain

20 Jun, 16 | by Emma Gray

Proportion likely to rise as population ages; major cause of disability and distress

Between a third and half (43%) of the UK population—roughly 28 million adults—lives with chronic pain, finds an analysis of the available evidence, published in the online journal BMJ Open.

This proportion is likely to rise as the population ages, warn the researchers, who add that chronic pain is a major cause of disability and distress among those affected by it.

There is no consensus on the proportion of people living with long term pain in the UK, and in a bid to try and gain an accurate picture, the researchers trawled relevant databases to find research on different types of pain, published after 1990.

Their search included studies on population based estimates of chronic pain—defined as lasting more than 3 months—chronic widespread pain, fibromyalgia (a rheumatic condition characterised by muscular or musculoskeletal pain), and chronic neuropathic pain (pain caused by nerve signalling problems).

From among 1737 relevant articles, 19 studies, involving just under 140,000 adults, were deemed suitable for inclusion in the final analysis.

They pooled the study data to arrive at an estimate of the prevalence of chronic pain, overall, and chronic widespread pain. Summary estimates were also drawn up for moderate to severely disabling chronic pain, fibromyalgia, and chronic neuropathic pain among UK adults.

Based on seven studies, the researchers worked out that the prevalence of chronic pain ranged from 35% to 51% of the adult population, with the prevalence of moderate to severely disabling chronic pain (based on four studies), ranging from 10% to 14%—equivalent to around 8 million people.

Pooling of the data showed that 43% of the population experience chronic pain, and 14% of UK adults live with chronic widespread pain. The summarised data also showed that 8% of UK adults experience chronic neuropathic pain, and 5.5% live with fibromyalgia.

Twelve of the studies categorised the prevalence of pain by age group, and unsurprisingly, these showed that older people were more likely to live with pain over the long term.

Among 18-25 year olds, the prevalence was 14%, although it may be as high as 30% among 18-39 year olds, the analysis indicates—a sizeable chunk of the working population, say the researchers.

Among those aged 75 and above, the prevalence was almost two thirds (62%), suggesting that if current trends continue, the burden of chronic pain may increase further still as the population ages, say the researchers.

Women were more likely than men to be affected by chronic pain, irrespective of age or pain type.

The researchers point out that the included studies varied considerably, and that not all of them were of high quality, so making it difficult to draw firm conclusions.

The studies showed gradually increasing prevalence of chronic pain over time, from 1990. And the researchersestimate that the prevalence of chronic pain in the UK is now around 43%, equating to around 28 million people, based on population stats for 2013.

“Such prevalence data does not itself define need for care or targets for prevention, but reliable information on prevalence will help to drive public health and healthcare policymakers’ prioritisation of this important cause of distress and disability in the general population,” they conclude.

Drug treatment of hyperactivity in kids may have levelled off in UK

20 Jun, 16 | by Emma Gray

But it lasts much longer than it does in rest of Europe or US

The tendency to treat childhood hyperactivity (ADHD) with drugs may have reached a plateau in the UK, following a steep rise in the number of prescriptions for these medicines over the past 20 years, reveals research published in the online journal BMJ Open.

But when kids with attention deficit and hyperactivity disorder (ADHD) do go down the pharmacological route, their treatment lasts for much longer than that of their European or US peers, the findings show.

Drugs are one of several treatment options for ADHD, which includes parental training and behavioural therapies. ADHD drugs have been in use since the 1960s and are on the World Health Organization’s list of essential medicines for common psychiatric disorders.

The researchers base their findings on an analysis of Clinical Practice Research Datalink (CPRD) records, relating to children up to the age of 16 who had been prescribed at least one drug to treat ADHD between 1992 and 2013.

The CPRD is one of the world’s largest collections of long term anonymised primary care medical records. It is broadly representative of the UK population, covering around 8% of the total.

The researchers analysed the data to estimate trends in ADHD prescribing patterns among children between 1995 and 2013, and the length of treatment for those diagnosed with the condition.

During this period, 14,748 children under the age of 16 (85% of them boys) were given at least one prescription for an ADHD drug, with methylphenidate accounting for 94% of all prescriptions.

Over half (58%) of the children received their first prescription between the ages of 6 and 11; around 4% were 5 years old when they were first prescribed an ADHD drug.

The use of these drugs in this age group soared by a factor of 35, from 1.5 per 10,000 children in 1995 to 50.7/10,000 in 2008, after which it seemed to level off at 51.1/10,000 children by 2013.

The rate of new prescriptions rose 8-fold over the same timeframe, reaching 10.2 per 10,000 children in 2007, but subsequently falling to 9.1/10,000 in 2013.

These patterns may reflect the impact of National Institute for Health and Care Excellence guidelines issued in 2008, and/or concerns about the potential impact on the heart of long term use, suggest the researchers.

UK prescribing rates for ADHD drugs are considerably lower than they are in many other countries, the researchers point out. They are 10 times lower than in the US, up to 5 times lower than in Germany, and 4 times lower than in the Netherlands, although UK rates are twice as high as in France.

Nevertheless, the course of treatment tends to be longer than in these countries, the published evidence indicates. More than three out of four UK children (around 77%) were still being prescribed ADHD drugs 1 year after diagnosis and 60% were still on treatment 2 years later, the figures show.

The probability of stopping ADHD drugs within six years seemed to be higher in 11-15 year olds than it was in 6-10 year olds, the data showed, which may indicate that treatment is being stopped too early among young adults, say the researchers.

This is an observational study, and the researchers point out that their analysis cannot determine the causes behind the prescribing patterns they found. Furthermore, the data relate only to  the issuing of prescriptions, and not to their being dispensed or drugs actually taken.

But they conclude: “Although the prevalence and incidence of ADHD drug use in children have substantially increased during the past two decades, it seems that it may have reached a plateau recently…Our study indicates a turning point in the patterns of ADHD drug prescribing in children in the UK.”

Prolonged sitting, non-fatal self-harm, and institutional mental healthcare: Most read articles in May

6 Jun, 16 | by Emma Gray

Prolonged sitting and fatigue, non-fatal self-harm, and trends in institutional mental healthcare in Western Europe

File:Une femme lisant à la biblothèque des Champs Libres de Rennes.jpg

This month sees a mixture of some old favourites and some new entries in the Top 10 Most Read list. First up is a pilot study by Wennberg et al which uses a randomised two-condition crossover trial to compare the acute effects of uninterrupted sitting with sitting interrupted by brief bouts of light-intensity walking on self-reported fatigue, cognition, neuroendocrine biomarkers and cardiometabolic risk markers in overweight and obese adults. Kristensen et al‘s paper on the effect of statins remains popular at number two this month and at number four we have an observational study by Geulayov et al which received a press release – it examines trends in non-fatal self-harm and its management in England. In at number five this month is a study by Chow et al investigating how institutional mental healthcare has changed in Western Europe since 1990, finding that there are ongoing overall trends of a decrease in the number of psychiatric hospital beds and an increase in the number of places in other institutions, including prisons. Last month’s most read paper by Gunn et al remains in the top ten, and at number ten we have a new entry by Laver et al with a systematic review of systematic reviews, assessing the effects of interventions to delay functional decline in people with dementia.
