Extent of regretted sexual intercourse among young teenagers in Scotland: a cross sectional survey

This cross sectional survey determined the extent of regretted sexual intercourse among young teenagers in Scotland. Using a questionnaire, data were obtained from 7395 third-year pupils (3365 boys and 3730 girls) aged 13 years and 6 months to 14 years and 9 months in 24 nondenominational state secondary schools. Regretted sexual intercourse, measured on a three-point scale, was analyzed by ordinal logistic regression. The data revealed that 18% (661) of boys and 15.4% (576) of girls had experienced sexual intercourse, of which 74.8% occurred since their 13th birthday. Boys, compared with girls, reported higher levels of regret. For boys, higher levels of regret were significantly associated with having exerted pressure to have sex. On multivariate analysis, reports of being pressured, exerting pressure, not having planned sexual intercourse with partner, and high levels of parental monitoring were significantly related to girls' regret. For women, regret seemed to be related to lack of control. Sex education should focus on assisting young people to develop relationship and negotiation skills. In addition, making teenagers aware of potential emotional and relationship consequences of early sexual intercourse may delay first intercourse.     

Lipid concentrations and the use of lipid lowering drugs: evidence from a national cross sectional survey

ObjectiveTo evaluate the prevalence of the use of lipid lowering agents and its relation to blood lipid concentrations in English adults.DesignCross sectional survey.SettingEngland, 1998.ParticipantsNationally representative sample of 13 586 adults (aged ⩾16 years) living in non-institutional households.Results Mean total cholesterol concentrations were 5.47 (SE 0.02) mmol/l in men and 5.59 (0.02) mmol/l in women. Mean HDL cholesterol concentrations were 1.28 (0.01) mmol/l in men and 1.55 (0.01) mmol/l in women. Overall, of 10 569 adults who had a valid cholesterol measurement taken 7133 (67.5%; 95% confidence interval 66.5% to 68.4%) had a total cholesterol concentration ⩾5 mmol/l, 2804 (26.5%; 25.7% to 27.4%) had a ratio of total cholesterol to HDL cholesterol ⩾5 mmol/l, and 237 (2.2%; 1.9% to 2.5%) reported taking lipid lowering drugs. Of 117 participants with no history of cardiovascular disease but whose estimated 10 year risk of coronary heart disease was ⩾30% and whose total cholesterol concentration was ⩾5 mmol/l, four (3%) were taking lipid lowering drugs. Of 385 adults aged 16-75 with a history of coronary heart disease and eligible for lipid lowering treatment, 114 (30%; 25% to 34%) were taking lipid lowering drugs, of whom only 50 (44%; 35% to 53%) had a total cholesterol concentration <5 mmol/l.ConclusionsDespite the high prevalence of dyslipidaemia in English adults, the proportion of adults taking lipid lowering drugs in 1998 was only 2.2%. Rates of treatment were low among high risk patients eligible for primary prevention with lipid lowering drugs, and less than one third of patients with established cardiovascular disease received such treatment.     

Bullying behaviour and psychosocial health among school students in New South Wales,Australia: cross sectional survey

ObjectivesTo examine the prevalence of bullying behaviours in schoolchildren and the association of bullying with psychological and psychosomatic health.DesignCross sectional survey.SettingGovernment and non-government schools in New South Wales, Australia.Participants3918 schoolchildren attending year 6 (mean age 11.88 years), year 8 (13.96), and year 10 (15.97) classes from 115 schools.ResultsAlmost a quarter of students (23.7%) bullied other students, 12.7% were bullied, 21.5% were both bullied and bullied others on one or more occasions in the last term of school, and 42.4% were neither bullied nor bullied others. More boys than girls reported bullying others and being victims of bullying. Bullying behaviour was associated with increased psychosomatic symptoms. Bullies tended to be unhappy with school; students who were bullied tended to like school and to feel alone. Students who both bullied and were bullied had the greatest number of psychological and psychosomatic symptoms.ConclusionsBeing bullied seems to be widespread in schools in New South Wales and is associated with increased psychosomatic symptoms and poor mental health. Health practitioners evaluating students with common psychological and psychosomatic symptoms should consider bullying and the student’s school environment as potential causes.

Key messages

• Bullying behaviour occurs in schools worldwide and is likely to be associated with poor health in schoolchildren
• Research into bullying has been mainly focused on victims but there are other categories of bullying that deserve attention
• At least three out of five students experienced or participated in bullying in schools in New South Wales, Australia
• The psychosocial and psychosomatic health of the students varied according to their bullying status

     

Birth weight of offspring and insulin resistance in late adulthood: cross sectional survey

ObjectiveTo investigate the association between birth weight of offspring and mothers'' insulin resistance in late adulthood.DesignCross sectional survey.SettingGeneral practitioner''s surgeries in 23 towns in Great Britain.Participants4286 women aged 60-79 years.ResultsBirth weight of offspring was inversely related to maternal insulin resistance in late adulthood. For each 1 kg higher birth weight of offspring, women had a 15% reduction in the odds of being in the fourth with highest insulin resistance, compared to other fourths (odds ratio 0.85; 95% confidence interval 0.71 to 1.00). This increased to 27% (0.73; 0.60 to 0.90) after adjusting data for potential confounders. A U shaped relation between birth weight of offspring and diabetes in older age was found; women with the lightest and heaviest offspring had the highest prevalence of diabetes.ConclusionsBirth weight of offspring is inversely related to the mother''s insulin resistance in late adulthood, despite the association of glucose intolerance during pregnancy with heavier offspring at birth. Common genetic factors contribute to the relation between birth weight and risk of cardiovascular disease and diabetes in adults.

What is already known on this topic

Small birth weight is related to increased risk of cardiovascular disease and diabetes in adulthood; the underlying mechanisms are unclearSmall birth weight of offspring is related to parental cardiovascular disease, suggesting that common genetic factors affect birth weight and the risk of disease in adulthoodGenetic factors associated with the metabolism of insulin are plausible in linking birth weight and cardiovascular disease (the fetal insulin hypothesis)

What this study adds

Birth weight of offspring is inversely related to maternal insulin resistance in older ageGenetic factors related to both insulin resistance and birth weight explain at least part of the association between birth weight and risk of cardiovascular disease and diabetes in adulthood     

Doctors' use of electronic medical records systems in hospitals: cross sectional survey

ObjectivesTo compare the use of three electronic medical records systems by doctors in Norwegian hospitals for general clinical tasks.DesignCross sectional questionnaire survey. Semistructured telephone interviews with key staff in information technology in each hospital for details of local implementation of the systems.Setting32 hospital units in 19 Norwegian hospitals with electronic medical records systems.Participants227 (72%) of 314 hospital doctors responded, equally distributed between the three electronic medical records systems.ResultsMost tasks listed in the questionnaire (15/23) were generally covered with implemented functions in the electronic medical records systems. However, the systems were used for only 2-7 of the tasks, mainly associated with reading patient data. Respondents showed significant differences in frequency of use of the different systems for four tasks for which the systems offered equivalent functionality. The respondents scored highly in computer literacy (72.2/100), and computer use showed no correlation with respondents'' age, sex, or work position. User satisfaction scores were generally positive (67.2/100), with some difference between the systems.ConclusionsDoctors used electronic medical records systems for far fewer tasks than the systems supported.

What is already known on this topic

Electronic information systems in health care have not undergone systematic evaluation, and few comparisons between electronic medical records systems have been madeGiven the information intensive nature of clinical work, electronic medical records systems should be of help to doctors for most clinical tasks

What this study adds

Doctors in Norwegian hospitals reported a low level of use of all electronic medical records systemsThe systems were mainly used for reading patient data, and doctors used the systems for less than half of the tasks for which the systems were functionalAnalyses of actual use of electronic medical records provide more information than user satisfaction or functionality of such records systems     

Prevalence of dysfunctional breathing in patients treated for asthma in primary care: cross sectional survey

ObjectivesTo estimate the prevalence of dysfunctional breathing in adults with asthma treated in the community.DesignPostal questionnaire survey using Nijmegen questionnaire.SettingOne general practice with 7033 patients.ParticipantsAll adult patients aged 17-65 with diagnosed asthma who were receiving treatment.Results227/307 patients returned completed questionnaires; 219 (71.3%) questionnaires were suitable for analysis. 63 participants scored ⩾23. Those scoring ⩾23 were more likely to be female than male (46/132 (35%) v 17/87 (20%), P=0.016) and were younger (mean (SD) age 44.8 (14.7) v 49.0 (13.8, (P=0.05). Patients at different treatment steps of the British Thoracic Society asthma guidelines were affected equally.ConclusionsAbout a third of women and a fifth of men had scores suggestive of dysfunctional breathing. Although further studies are needed to confirm the validity of this screening tool and these findings, these prevalences suggest scope for therapeutic intervention and may explain the anecdotal success of the Buteyko method of treating asthma.

What is already known on this topic

Abnormal breathing patterns may cause characteristic symptoms and impair quality of lifeEffective interventions exist for dysfunctional breathingDysfunctional breathing has been described in patients attending hospital respiratory clinics

What this study adds

29% of adults treated for asthma in primary care had symptoms suggestive of dysfunctional breathingAffected patients were more likely to be female and younger, but no differences were found with severity of asthmaSome patients with asthma may benefit from breathing therapy     

A cross sectional survey for B virus antibody in a colony of group housed rhesus macaques

A systematic sampling technique was used in combination with a highly sensitive and specific ELISA to provide unbiased age-specific prevalence estimates of B virus antibody in rhesus monkeys housed in three different outdoor breeding corrals. Among 146 sampled monkeys, 97% of animals 2.5 years and older were seropositive, while only 22% of younger animals were seropositive. Neither gender nor social dominance ranking were predictive of B virus antibody status. The strong age association was not inconsistent with hypothesized venereal transmission of B virus. Improvements in the epidemiologic understanding of B virus are necessary to assist efforts to eradicate this agent from breeding colonies of rhesus monkeys.     

Referral for menstrual problems: cross sectional survey of symptoms,reasons for referral,and management

ObjectivesTo describe the menstrual experience of women referred for menstrual problems, in particular menorrhagia (excessive menstrual loss), and to assess associations with reasons for referral given by their general practitioners, the women''s understanding of the reasons for their attendance at the hospital clinics, and clinic outcome.DesignQuestionnaire survey, with partial review of case notes after 8 months.SettingThree hospital gynaecology clinics in Glasgow and Edinburgh.Participants952 women completed the questionnaire, and the first 665 were reviewed.ResultsOnly 38% (95% confidence interval 34% to 41%) of women reported excessive menstrual loss as a severe problem. However 60% (57-63%) gave it as reason for attending a clinic, and 76% (73-79%) of general practitioners gave it as reason for referral. Reason for referral was significantly biased towards bleeding (McNemar odds ratio 4.01, 3.0 to 5.3, P<0.001) and against pain (0.54, 0.4 to 0.7, P<0.001). Dysfunctional uterine bleeding was diagnosed in 37% (31-42%) of the 259 women who gave as reason for attendance something other than bleeding. Women who were economically disadvantaged differed in prevalence of the main diagnoses and were more likely to fail to reattend. Hysterectomy was associated with referral for bleeding (relative risk 4.9, 1.6 to 15.6, P<0.001) but not with the patient stating bleeding as the reason for clinic attendance.ConclusionsIntolerance of the volume of their bleeding is not a key feature among women attending clinics for bleeding problems. Broad menstrual complaint tends to be reframed as excessive bleeding at referral and during management. This may result in women receiving inappropriate care. Conceptualisation and assessment of menorrhagia requires reconsideration.

What is already known on this topic

Excessive menstrual loss (menorrhagia) is one of the commonest reasons for secondary referral of women, but there is no formalised clinical assessment in routine useManagement typically involves potent drugs or invasive surgery, with 60% of women having hysterectomy within 5 yearsMany women referred for menorrhagia have menstrual blood loss that is not excessive

What this study adds

Discordance exists between symptoms and both referral and diagnostic pathways, arising from a disproportionate focus on menstrual bleedingAmong women referred for menorrhagia, volume of bleeding is not a key symptomThis raises concerns about conceptualisation and assessment of menstrual complaint and the appropriateness of healthcare provision     

Sexual behaviour of adolescents in Nigeria: cross sectional survey of secondary school students

ObjectivesTo determine whether family structure (polygamous or monogamous) is associated with sexual activity among school students in Nigeria.DesignCross sectional school survey with a two stage, clustered sampling design.Participants4218 students aged 12-21 years attending 39 schools in Plateau state, Nigeria. Responses from 2705 students were included in the analysis.ResultsOverall 909 students (34%) reported ever having had sexual intercourse, and 1119 (41%) reported a polygamous family structure. Sexual activity was more common among students from polygamous families (42% of students) than monogamous families (28%) (χ²=64.23; P<0.0001). Variables independently associated with sexual activity were male sex (adjusted odds ratio 2.52 (95% confidence interval 2.05 to 3.12)), older age (1.62 (1.24 to 2.14)), lower sense of connectedness with parents (1.87 (1.48 to 2.38)), having a dead parent (1.59 (1.27 to 2.00)), family polygamy (1.58 (1.29 to 1.92)), lower sense of connectedness with school (1.25 (1.09 to 1.44)), and lower educational level of parents (1.14 (1.05 to 1.24)). Multistep logistic regression analysis showed that the effect of polygamy on sexual activity was reduced by 27% by whether students were married and 22% by a history of forced sex.ConclusionsSecondary school students in Nigeria from a polygamous family structure are more likely to have engaged in sexual activity than students from a monogamous family structure. This effect is partly explained by a higher likelihood of marriage during adolescence and forced sex. Students'' sense of connectedness to their parents and school, regardless of family structure, decreases the likelihood of sexual activity, and fostering this sense may help reduce risky sexual behaviour among Nigerian youth.

What is already known on this topic

In 2000 Nigeria developed a national health policy aimed at preventing behaviour among adolescents leading to sexually transmitted infections (including HIV), pregnancy, and dropout from schoolEffective interventions in Nigeria have been hampered by inadequate information on contextual factors associated with sexual behaviour of adolescentsIn Western countries adolescents'' sense of connectedness to their parents and to school is inversely associated with risky sexual behaviour, but these effects may differ in countries where polygamy is prevalent and where school attendance is low

What this paper adds

A polygamous family structure is associated with early sexual activity among adolescents, an effect partly explained by a higher likelihood of marriage and history of forced sexual intercourseA greater sense of connectedness to parents and school decreases the likelihood of sexual activity, regardless of family structure     

The health of children in refuges for women victims of domestic violence: cross sectional descriptive survey

ObjectivesTo describe the health and developmental status of children living in refuges for women victims of domestic violence and to investigate their access to primary healthcare services.DesignCross sectional survey.SettingWomen''s refuges in Cardiff.Participants148 resident children aged under 16 years and their mothers.Results148/257 (58%) children living in refuges between April 1999 and January 2000 were assessed. Child health system data were incorrect (general practitioner and/or address) or unavailable for 85/148 (57%) children. Uptake of all assessments and immunisations was low. 13/68 (19%) children aged <5 years had delayed or questionable development on the Denver test, and 49/101 (49%) children aged 3-15 years had a Rutter score of >10 (indicating probable mental health problems). Concerns were expressed by mothers of 113/148 (76%) children. After leaving the refuge, 22 children were untraceable and 36 returned home to the perpetrator from whom the families had fled.ConclusionsThe children had a high level of need, as well as poor access to services. Time spent in a refuge provides a window of opportunity to review health and developmental status. Specialist health visitors could facilitate and provide support, liaison, and follow up.

What is already known on this topic

A pilot study showed poor uptake of immunisations and surveillance among children who live in refuges for women victims of domestic violenceQualitative studies suggest that these children are at risk of psychological ill health

What this study adds

Baseline health and demographic data show that children in refuges have a high level of unmet health need, particularly in relation to mental health difficultiesTheir families have poor access to health services
