Design Cross sectional household survey.
Setting All regions of England 2005.
Participants 10 503 adults aged 16 and over identified with a two stage selection process: random selection of geographical areas and filling predefined quotas of individuals. Results weighted to reflect the national demographic profile of adults aged 16 and over.
Main outcome measures Estimates of the prevalence of body piercing overall and by age group, sex, and anatomical site. Estimates, in those aged 16-24, of the proportion of piercings associated with complications and the seeking of professional help.
Results The prevalence of body piercing was 1049/10 503 (10%, 95% confidence interval 9.4% to 10.6%). Body piercing was more common in women than in men and in younger age groups. Nearly half the women aged 16-24 reported having had a piercing (305/659, 46.2%, 42.0% to 50.5%). Of the 754 piercings in those aged 16-24, complications were reported with 233 (31.0%, 26.8% to 35.5%); professional help was sought with 115 (15.2%, 11.8% to 19.5%); and hospital admission was required with seven (0.9%, 0.3% to 3.2%).
Conclusions Body piercing is common in adults in England, particularly in young women. Problems are common and the assistance of health services is often required. Though serious complications requiring admission to hospital seem uncommon, the popularity of the practice might place a substantial burden on health services.
Published studies in other developed countries report a prevalence of body piercing ranging from 4.3% to 51%.5 6 7 8 9 10 The wide variation in estimates is due to factors such as the time and location of the studies, the different population groups participating, and different definitions of piercing used. Most studies have surveyed adolescents or young adults with most using convenience samples, in which selection bias is likely to have a major influence on the findings. Three surveys of the general population provide estimates of prevalence of body piercing (excluding earlobe piercing) of between 6.7% and 14%.11 12 13 Two of these were recent studies, but none of them was performed in the United Kingdom.
Estimates of the proportion of body piercings that develop complications range from 17% to 70%, the variation again probably due to the different definitions used and populations studied.5 7 14 15
Analysis of hospital episode statistics in England and Wales found that the annual incidence of auricular perichondritis more than doubled from 1990-1 to 1997-8.16 The rise is thought to be caused by the increasing popularity of high ear piercing—that is, in the upper third of the pinna. Of 115 general practitioners who responded to a survey in Bury and Rochdale in 1999, 95% stated that they had seen a patient with a complication of piercing.17 Whittle and Lamden found that 62 of 64 dentists in south Lancashire had seen patients with lip or tongue piercings in the previous 12 months.18 Patients with associated oral health problems had been seen by 44% of respondents. Both surveys had response rates of around 60%.
We estimated the prevalence of body piercing in England; the proportion of piercings that resulted in complications; and the proportion of piercings that resulted in complications serious enough for further help to be requested. We did this by sampling the general population of England aged 16 and over.
The selection of adults was two stage. The first stage involved random sampling of geographical areas and the second stage the sampling of individuals to fill predefined quotas. Primary sampling units were small neighbourhoods of about 300 households. Sampling of these units was stratified and proportional across all combinations of the 10 standard regions of England and 56 ACORN types. (The ACORN type of a particular neighbourhood is based on a number of demographic statistics and lifestyle variables (www.caci.co.uk/acorn/). A total of 694 different neighbourhoods were sampled, and these were considered to be representative of neighbourhoods in England.
Within a primary sampling unit, the selection of adults was non-random. Interviewers were provided with a list of possible addresses, and quota controls were set in terms of sex, age group, and employment status. Individuals were interviewed at various times (including the evenings and weekends). Only one individual was interviewed at each address. After completing an interview, the interviewers were directed not to attempt interviews in the next or next but one house or flat.
We designed the questionnaire with the research company. A piercing was defined in the questionnaire as "an opening in any part of the body (except the earlobes) through which jewellery might be worn." We did not distinguish between piercings that were currently patent and those that had been allowed to heal over. We excluded soft earlobe piercings to achieve a larger sample size than would otherwise have been possible. Individuals were first asked "Have you ever had any body piercings—that is, NOT including any earlobe piercings?" Those who reported having ever had such a piercing were then asked a series of questions. For each of a maximum of 10 piercings recorded in the survey, the respondent was asked "Where on the body is/was the piercing?" To this they were allowed to record one of navel (belly button), tongue, nose, ear, nipple, lip, eyebrow, genital, other, and don’t know. They were then asked "Which, if any, of the following health problems did you experience?" To this they were allowed to record one or more of the following health problems: none, swelling, bleeding, infection, tear or injury, allergy, other, and don’t know. If a health problem was recorded, the respondent was asked "Which, if any, of the following sources of professional help did you use?" To this they were allowed to record one or more of the following sources of professional help: none, piercer, NHS Direct, pharmacist, general practitioner, accident and emergency department, hospital admission, other, and don’t know. Respondents answered questions themselves on a laptop computer without having to divulge responses to the interviewer. Interviewers showed the respondent how to use the laptop with a couple of practice questions.
We used sampling weights to make results more representative of
adults aged 16 or over in England and of the piercings they have. The
research company provided the sampling weights, which we used in all
analyses. These weights were based on the national demographic
profile of adults in England aged 16 or over. We used demographic
variables to weight the sample (sex, working full time or not, with
or without children, age group (16-24, 25-34, 35-44, 45-54, 55-64,
65), social grade (AB, C1, C2,
D, E),19 and region). In an analysis of all individuals
surveyed, we standardised weights so that the sum of the weights
equalled the total number of all individuals surveyed (10 503). In
an analysis of all piercings, we standardised weights so that
the sum of the weights equalled the total number of reported
piercings (1943). In an analysis of all piercings in 16-24 year
olds, we standardised weights so that the sum of the weights
equalled the total number of reported piercings in that age group
(754).
We based confidence intervals and significance tests on the modified sandwich estimator of variance20 21 allowing for the clustering of the sample within the primary sampling units and the stratification of the sampling by region. This had the effect of widening confidence intervals and increasing P values. The size of the allowance made depended on the particular analysis. The design effect for the overall prevalence of body piercing was 1.20. All data management and analyses (after we received the data from BMRB) were performed with Stata 8.2 (StataCorp, College Station, TX).
BMRB complies with the Market Research Society’s Code of Conduct and guidelines, and is British Standard BS7911/Market Research Quality Standards Association MRQSA certified. All data were managed in accordance with the Data Protection Act 1998.
We estimated that 10% of adults (95% confidence interval 9.4% to
10.6%, 1049/10 503) have ever had a body piercing (table 1)
. The mean number
of piercings per pierced individual was 1.71. Seven individuals
reported having had at least 10 piercings.
In each age group piercing was more common in women than men
(data not shown) and was about three times more common in women
than men overall (table 1).
Piercing was much more common
in younger age groups (table 1).
Indeed there was a steady and
marked fall in prevalence with increasing age. Nearly half the
women aged 16-24 reported having had a piercing (305/659, 46.2%,
42.0% to 50.5%) (table 1).
Piercing was significantly less common in social
grades A and B than in lower grades (table 1).
Piercing was
significantly less common in London than in other regions (prevalence
ratio 0.68, 0.55 to 0.84; P<0.001) (table 1).
Further analysis showed
that this could not be explained by differences in age group, sex, or
social grade.
Of all 1934 piercings, 33% were at the navel, followed by nose
(19%), ear (13%), tongue (9%), nipple (9%), eyebrow (8%), lip
(4%), genitals (2%), and some other part of the body (3%) (table
2)
.
The anatomical sites used for piercing varied by sex (table 2).
In women, the
most common piercings were, in order: navel, nose, ear, tongue,
eyebrow, nipple, lip; and in men: nipple, eyebrow, ear, tongue, nose,
lip, genitals. Thus nipple piercing was the most popular in men, but
one of the least popular in women, while navel piercing was by far
the most popular in women (accounting for more than a third of all
piercings in women) and much rarer in men (table 2).
Genital piercing was not
popular but is estimated to be about twice as common in men than
in women (although small numbers mean that the evidence for this
is limited, P=0.1) (table 2).
All sites of piercing were
more common among 16-24 year olds than those who were older;
this was particularly the case for lip and tongue piercings
(table 3)
.
Four in five (1564/1943, 80%) piercings were performed in specialist
piercing/tattooing shops (table 4)
, and with certain piercings
such as tongue and navel, about 90% were performed in specialist
shops. A worrying 9% of tongue piercings, however, were performed
by "non-specialists." Compared with other types of piercings,
piercings of the ears (excluding lobes), nose, lips, and genitals
were more likely to be performed by "non-specialists." At each
anatomical site, even genital and tongue, several piercings
were reported as having been performed by the individuals themselves
or by a friend or relative (table 4).
Complications
In our analysis we first examined all
complications together and then only those that resulted in the
seeking of further help as an indication of severity. Overall,
complications were reported in 533/1940 (27.5%, 24.8% to 30.3%)
piercings, with problems thought serious enough to seek further help
in 250/1940 (12.9%, 10.8% to 15.2%). From the data collected it is
not possible to tell when piercings were performed or when
complications occurred. An analysis of piercings in the group aged
16-24, in whom piercings and subsequent complications are likely
to have been in the recent past, provides a more reliable basis
for identifying which type of piercing is more likely to result
in a complication. In this age group we found slightly higher
proportions of piercings in which complications developed and
respondents sought further help (table 5)
.
The most common problems reported with piercings in those aged
16-24 were swelling, infection, and bleeding. Problems were
most likely to be reported with tongue piercings (50%), followed
by piercings of the genitals (45%) and nipple (38%). Help was
most likely to be sought for piercings of the genitals (45%),
followed by the nipple (25%) and tongue (24%). At the more unusual
sites such as genitals, however, the estimated percentage of
piercings resulting in a complication is not precise because of
the small numbers of piercings identified. Although not significantly
different, piercings performed by a friend or relation, a
non-specialist shop, or a mobile piercer, seemed more likely to
result in a complication than piercings performed in a specialist
piercing/tattooing shop (table 5).
Serious complications that
resulted in a hospital admission were significantly more likely to
occur with piercings performed by a non-specialist (4/134, 3.0%, 0.7%
to 11.9%) than with piercings performed by someone at a specialist
piercing or tattooing shop (3/620, 0.5%, 0.1% to 2.0%) (P=0.01).
Help was sought most often from pharmacists, piercers, and
general practitioners. Almost one in every 100 piercings in this
age group resulted in a hospital admission.
The choice of anatomical site for piercing clearly varies by sex. In our survey, women particularly favoured navel, nose, ear, and tongue piercings, whereas men favoured nipple, eyebrow, ear, and tongue piercings. Nipple, eyebrow, and genital piercings were more common in men than women. Although not much favoured by men, navel piercings were by far the most common piercing, accounting for 33% (639/1943). Other studies have shown sex differences in choice of piercing site, although the most popular sites vary slightly by population studied. All piercings were more common in young people, but the fact that piercings of the lip and tongue were particularly popular in those aged 16-24 suggests that oral piercings are a more recent fashion and that people might be becoming more adventurous. That piercing was less common in London than other regions might be related to ethnic, cultural, or religious differences.
About a third of all complications were associated with navel piercings, the most common type of piercing. Tongue piercings, however, most often resulted in a complication (usually swelling). About a half of tongue piercings resulted in a complication and about a quarter resulted in help being sought. Intimate (nipple and genital) piercings were less common but the chances of a complication occurring were relatively high (about a quarter of nipple piercings and about a half of all genital piercings resulting in help being sought). A high level of complications with such piercings has been reported by others.22 Interestingly, help was sought in a greater proportion of complications at the ear, nipple, and genital as opposed to other sites. This could indicate that, should a complication occur at these sites, there is a greater chance of it being considered serious by the individual concerned.
Although most problems associated with piercing are usually minor and self limiting, some complications are serious and can be fatal. There is some evidence to support the concerns raised about the transmission of bloodborne viruses through body piercing.23 Our study was not designed to identify such rare complications, but piercers, people choosing to be pierced, and healthcare providers need to be aware of the possible serious negative outcomes of body piercing.
Most piercings were performed in specialist piercing or tattooing shops, although about 20% were performed outside of these settings. Self piercings were reported at every anatomical site we asked about, even the tongue. Piercings in settings other than specialist piercing/tattooing shops were more likely to result in a complication for which help was sought (22% of piercings by non-specialists compared with 14% of piercings by specialists, P=0.13) and were significantly more likely to result in a complication requiring a hospital admission (3% of piercings by non-specialists compared with 0.5% of piercings by specialists, P=0.01).
Our estimate of prevalence of body piercing overall and our finding that piercing was more common in women than men and in younger age groups support those of similar studies carried out in other developed countries.11 12 13 Our study supports and extends the information presented by Laumann and Derick on the proportion of piercings in which complications developed, and the proportion of piercings performed by different providers.13
Limitations
Our study might have been subject to some
selection bias as the selection of the sample was not truly random.
Moreover, it is not known how many approaches led to a refusal or no
contact being made, potentially introducing a further selection
bias to our results. Our estimates could have been affected if
individuals with body piercings were more or less likely to be at
home or more or less willing to participate in research. We
consider that the sampling method and corrective weighting used,
however, produced good estimates for all adults and all body
piercings (excluding earlobe piercings) in the population aged 16 or
over and living in England.
Data were collected with a self completed questionnaire to avoid embarrassment with regard to intimate piercings, but some recall or response bias remains possible. The maximum number of piercings recordable for each individual was 10. Of the seven individuals who reported at least 10, some bias could have occurred in their choice of which piercings to report. Respondents were limited to fixed categories of response and their responses were not verified. The detail of each complication was not captured and there could have been some misclassification, such as confusion between infection and allergy.
We did not collect data on the date of piercing and the date of any complications so it was impossible to estimate a proper risk. But piercings and complications in those aged 16-24 will have occurred in the fairly recent past and restricting an analysis of complications to these 754 piercings is a more reliable basis for identifying which type of piercing is more likely to result in a complication.
Conclusions
The findings of our study are important
because they provide background information showing that piercing is
common, particularly in young women; that complications are common;
and that health service providers are often called on to help. If
piercing remains fashionable, almost half the female population might
eventually have had a body piercing at a site other than the earlobe.
Even if serious complications are rare, the popularity of the
practice and the fact that complications can occur long after the
actual piercing, might place a considerable burden on health
services for many years. Health professionals need to be aware of
the potential complications of body piercing and the appropriate
management. More research is needed to determine which factors
increase the risk of complications so that this information can
be used to raise awareness in piercers, their clients, and health
services and to improve the safety of body piercing.
