Social environment and height: England and Scotland 1987 and 1988.

This study was designed to investigate the social characteristics associated with the height of primary schoolchildren aged from 5 to 11. Data were analysed for 8491 representative sample children measured in England and Scotland in 1987 and 1988 and 3203 inner city children measured in England in 1987. Height was negatively associated with social class but the association was not significant after allowing for biological variables. A negative gradient of height with size of sibship was evident in white children but was less so in Afro-Caribbean and Asian children. The individual associations of 11 different environmental characteristics were examined after allowing for biological factors and size of sibship. Consistent associations with height included a negative gradient of height with increasing latitude and an association of taller stature with increasing maternal age. A social class gradient in height is accounted for by associations with biological factors, particularly the parental heights; environmental attributes are weakly associated with height after allowing for biological factors.

Prevalence of asthma and wheeze in the Highlands of Scotland.

To establish the prevalence of asthma and wheeze in 12 year old children in a region with low background pollution levels, a population of children resident in the Highland Region of Scotland was studied by questionnaire supported by objective data. A respiratory questionnaire was distributed to the parents of 1919 children aged from 12-13 years and attending secondary schools in the educational divisions of Lochaber, Ross and Cromarty, and Inverness including Skye in Highland Region to ascertain history of wheeze and parental awareness of a diagnosis of asthma. Peak expiratory flow (PEF) measurements were carried out before and after a standardised exercise test. Ozone levels were noted. Questionnaires were completed by 1825 parents (95% of those invited) and 1702 (93%) of those returning questionnaires took part in the exercise test. The overall prevalence of reported asthma was 14% and wheeze 25%. Defined as a fall in PEF of more than 15% with exercise, the overall prevalence of exercise induced bronchospasm was 9%. In Skye the prevalence of reported asthma was 17%, wheeze 28%, and exercise induced bronchospasm 30%. There were no significant differences between areas for reported asthma or wheeze. There was, however, a highly significant difference between areas for exercise induced bronchospasm, most of which was accounted for by the very high incidence in Skye, which is one of the most rural of the areas studied. The results of this study do not support the hypothesis that asthma is commoner in urban than rural areas, whether we compare the Highlands with the rest of the UK or areas within the Highlands, or whether we examine reported symptoms or exercise induced bronchospasm. The results do not support an association between atmospheric pollution and the prevalence of asthma.

Audit of screening programme for congenital hypothyroidism in Scotland 1979-93.

OBJECTIVE: To evaluate the efficiency of the screening programme for congenital hypothyroidism in Scotland and to determine the outcome in the cohort of children with positive testing for thyroid stimulating hormone (TSH). DESIGN: Establishment of comprehensive database for all Scottish infants with high TSH, detected on Guthrie screening. SUBJECTS: 344 infants born between August 1979 and December 1993 with TSH greater than 40 mU/l on initial Guthrie, or 15-40 mU/l on repeat Guthrie. MAIN OUTCOME MEASURES: Ages at time of: (a) Guthrie collection, (b) notification of positive result by laboratory, and (c) start of treatment; audit of late diagnosis/missed cases; categorisation of positive cases into definite and probable congenital hypothyroidism, transient TSH elevation, and uncertain status; educational status of children with definite and probable congenital hypothyroidism. RESULTS: 344 positive cases were categorised as having definite (224) and probable (11) congenital hypothyroidism, transient TSH elevation (88), and status uncertain (21). The overall incidence of definite/probable congenital hypothyroidism was 1 in 4400 live births. For the definite/probable groups median age of Guthrie collection was consistently between 6 and 7 days from 1983 onwards but for the whole cohort was later than 10 days in 10.5%. Median age of notification fell from 14 days in 1980 to 11 days in 1993. Median age of starting treatment ranged between 11 and 15 days from 1983 onwards. Treatment was delayed in four cases, three due to failed or late Guthrie card submission. Of 149 children with definite/ probable congenital hypothyroidism who were of school age, educational status was ascertained in 139 (93%). Only two children (1.4%) were attending special school, one of whom was known to have mild hypothyroidism. Sixteen children (11.5%) were receiving extra help in mainstream education compared with 18% of control children in the Scottish very low birth weight study. CONCLUSION: The current screening programme is working well, but efficiency could be increased by earlier and more reliable Guthrie collection. A substantial proportion of children picked up on the screening programme have a transient rise in TSH rather than true congenital hypothyroidism. The incidence of special education and learning support in Scottish children with congenital hypothyroidism appears to be no different to that of the general population.

Prevalence and risk factors for joint pain among men and women in the West of Scotland Twenty-07 study.

OBJECTIVE: To examine the association between three modifiable risk factors (obesity, smoking, and alcohol consumption) and reported joint pain. METHODS: Cross sectional data were collected on 858 people aged 58 years living in the West of Scotland and on the same individuals four years later, aged 62 years. RESULTS: There was a positive relation between obesity and reported pain in the hips, knees, ankles, and feet. The strongest relation was with knee pain (odds ratio = 2.42 (95% confidence interval, 1.65 to 3.56)). There were no strong consistent associations between smoking habits and pain in any joint after adjusting for sex, alcohol consumption, body mass index, social class, and occupational exposures. Similarly, alcohol was not consistently related to pain in any joint in the fully adjusted models. CONCLUSIONS: Obesity had consistent and readily explained associations with lower limb joint pain. The data suggest that smoking behaviour and alcohol consumption are not consistently associated with joint pain across the body.

Common causes of blindness and visual handicap in the west of Scotland.

An analysis of blind registration forms was made to determine the commonest causes of blindness in the west of Scotland. It was found that the leading causes of blindness in order of frequency of incidence were senile macular degeneration, glaucoma, cataract, diabetic retinopathy, and myopic degeneration. Diabetic retinopathy was the leading cause of blindness among persons of working age.

Microbial contamination of contact lens cases in the west of Scotland.

A cross-sectional study of 178 asymptomatic contact lens wearers attending 10 contact lens practices in the west of Scotland was conducted over a 4 month period. The aims of the study were to identify specific microbial contaminants in lens cases, to determine the rate of contamination of such containers and to assess the value of the steps involved in different lens care regimens in the prevention of case contamination. Microbial contamination affected 53% of lens cases. Cases used with conventional wear and disposable systems were contaminated at similar rates and, therefore, the advantage of regular lens replacement may have been lost if these lenses were stored in contaminated cases. Four percent of lens cases were contaminated with amoebal species and all of these showed concomitant bacterial colonisation. These findings imply that case hygiene is probably as important as lens hygiene if new or disinfected lenses are not to be immediately re-contaminated by storage in dirty cases. Unfortunately simple and effective methods of lens and case disinfection, which would be suitable for use in the average home environment, are not yet available. It follows that frequent and regular disposal of lens cases may prove to be a necessary measure to prevent the build-up of microbial colonisation in such containers.

Snow sports injuries in Scotland: a case-control study.

OBJECTIVES: To examine the incidence and patterns of snow sports injuries at the three largest commercial ski areas in Scotland and to identify factors associated with injury risk. METHODS: A prospective case-control study of all injured people at Cairngorm, Glenshee, and Nevis Range ski areas during the 1999-2000 winter season. Personal details, snow sports related variables, diagnosis, and treatment were recorded. Control data were collected at random from uninjured people at all three areas. Random counts were performed to analyse the composition of the on slope population. RESULTS: A total of 732 injuries were recorded in 674 people. Control data were collected from 336 people. The injury rate for the study was 3.7 injuries per 1000 skier days. Alpine skiers comprised 67% of the on slope population, snowboarders 26%, skiboarders 4%, and telemark skiers 2%. Lower limb injuries and sprains were the commonest injuries in alpine skiers and skiboarders. Snowboarders sustained more injuries to the upper limb and axial areas. Skiboarders and snowboarders had a higher incidence of fractures. After adjustment for other variables, three factors were all independently associated with injury: snowboarding (odds ratio (OR) 4.07, 95% confidence interval (CI) 1.65 to 10.08), alpine skiing (OR 3.82, CI 1.6 to 9.13), and age <16 years (OR 1.9, CI 1.14 to 3.17). More than five days of experience in the current season and at least one week of experience in total had a protective effect against injury. CONCLUSIONS: Despite a change in the composition of the alpine population at Scottish ski areas, the overall rate and pattern of injury are similar to those reported previously in comparable studies. Several factors are associated with an increased risk of injury and should be targeted in future injury prevention campaigns.

Lead poisoning in rural Scotland.

Nine people from four families living in rural parts of Scotland have been found to suffer from clinical or biochemical effects of lead poisoning. Five had symptoms and four had unequivocal evidence of excessive lead exposure. The source of lead has been traced to the domestic water supply which in all cases was grossly contaminated with lead acquired from lead plumbing systems, including lead storage tanks. Clinical improvement followed the replacement of lead piping in two families studied. Lead poisoning is a possible cause of chronic ill health in areas of plumbosolvent water.

Salt and blood pressure in Scotland.

Dietary salt intake and urinary sodium excretion were compared in normotensive and hypertensive subjects in Renfrew, Scotland. All groups had high 24-hour urinary salt excretions, and hypertensive subjects did not eat or excrete more salt than normotensive subjects. The only significant relations found were a lower sodium excretion in hypertensive women than in normotensive women (p < 0.02) and a lower urinary sodium concentration in hypertensive men than in normotensive men (p < 0.05). These data provide no support for the hypothesis that dietary salt is a major cause of hypertension.

Research ethical committees in Scotland.

A questionnaire was sent to 41 ethical committees in Scotland requesting information about their constitution and supervision of clinical research. Thirty-four (83%) replies were received. Committees varied in size from one to 73 members, most of whom were medical. Ten had no nurse members and only three had lay members without direct NHS connections. Sixteen saw their role as advisory rather than supervisory. Thirteen had not met in the past year whereas two had held 10 or more meetings. Limited use (12) was made of standard protocols, and only six had formal procedures for monitoring research in progress. Only seven of 370 proposals were rejected outright. Risk/benefit dilemmas and difficulties relating to informed consent were the commonest problems encountered. The committees provide only limited safeguards for patients and research workers, and more effective, standardised procedures are indicated.

Diagnosis and treatment of venous thromboembolism by consultants in Scotland.

A questionnaire was sent to 508 consultants in Scotland likely to encounter deep vein thrombosis and pulmonary embolism to assess their current standard practice in diagnosis and treatment of these disorders. Replies were received from 358 (70.5%). In deep vein thrombosis 47% and in pulmonary embolism 33% of consultants usually depended on clinical observation alone for diagnosis. In deep vein thrombosis 37% used venography to supplement clinical diagnosis and in pulmonary embolism 13% used angiography and 53% used isotopic scanning. Almost all consultants treated deep vein thrombosis (95%) and pulmonary embolism (99%) with anticoagulants. Most consultants (81%) gave heparin by intravenous infusion. Although many consultants gave intravenous heparin for more than three days (49.5% in deep vein thrombosis and 61% in pulmonary embolism), 25% of these consultants did not use any laboratory monitoring of heparin's effect. Large numbers of consultants gave warfarin for more than three months (20% in deep vein thrombosis and 47% in pulmonary embolism). There was a significant tendency to give heparin (p less than 0.01) and warfarin (p less than 0.001) for longer periods in pulmonary embolism than in deep vein thrombosis. This survey shows a widely varying practice and underlines the need for further controlled studies to provide clear guidance in the management of deep vein thrombosis and pulmonary embolism.

Spina bifida and anencephaly in Scotland.

Data obtained from routine sources showed that from 1971 to 1982 the birth prevalences of spina bifida and anencephaly in Scotland fell. When known terminations after routine alpha fetoprotein screening were added to total births the adjusted birth prevalence could be calculated. In 1974-82 this fell by 40% for spina bifida (3 X 0-1 X 8) and 36% for anencephaly (2 X 2-1 X 4). These findings were compared with data on birth prevalences in England and Wales, Northern Ireland, and Glasgow. The fall in birth prevalences of spina bifida and anencephaly over the past decade appears to have been due both to a true fall in incidence as well as to increased screening and termination for these conditions.

A case-control study of cervical cancer screening in north east Scotland.

To estimate the relative risk of invasive cervical cancer in each succeeding year after a negative screening result the screening records of all women tested in the north east of Scotland were examined as the basis for a case-control study. The cases consisted of 115 women in whom invasive cervical cancer had been diagnosed in 1968-82 and who had appeared in the screening records at least once before diagnosis. For each patient five controls were selected from women of the same age who appeared in the screening records before the date of diagnosis in the patient. If the patient's cancer had been detected by screening the controls were chosen from women of the same age screened the same year. A comparison was made between cases and controls of the number of negative smears taken before the diagnosis. The results showed a high relative protection (inverse of the relative risk) in the first two years after a negative test, falling steadily as time since the last negative test elapsed. Even after 10 years, however, a considerable residual effect was observed.

Rett's syndrome in the west of Scotland.

Nineteen girls with characteristic features of Rett's syndrome, including normal initial development, regression at about 12 months of age, repetitive hand movements, and severe mental handicap were studied. This represents an estimated incidence of one in 30 000 live births (one in 15 000 girls) in the west of Scotland. Although the children were often initially considered to be autistic, they did not conform to this diagnosis as they made good personal contact within the limits of their mental development. The developmental regression was sometimes falsely attributed to vaccination. Each child showed striking involuntary movements and abnormality of tone, varying from hypotonia, which was found only in the youngest, to rigidity, which was common in older girls; this permitted classification into three clinical subtypes. The abnormalities were highly suggestive of an extrapyramidal disorder, and this has implications for further research and possible treatment.

Association between liberalization of Scotland's liquor licensing laws and admissions for self poisoning in West Fife.

Data were collected prospectively on 2868 consecutive patients admitted for self poisoning between 1971 and 1982. Analysis showed a dramatic increase in the frequency of alcohol taken in association with self poisoning, in both sexes, after the liberalization of Scotland's liquor licensing laws. This increase, however, did not appear to affect the severity of overdoses or the outcome. Total admission rates for self poisoning increased with relaxation of the liquor licensing laws, and since overdoses associated with alcohol tend to occur at night these impose considerable strain on casualty departments and acute admitting units.

Trends in suicide in Scotland 1974-84: an increasing problem.

A detailed investigation of trends in suicide rates in Scotland from 1974 to 1984 showed a complex pattern. Overall rates for men increased by 40% with the greatest increases in those aged 45-64. In contrast, rates for women showed a small decline, which was most noticeable in those aged 15-24. The well recognised decline in poisoning by domestic gas was seen over this period, and suicide by this method virtually stopped. Both sexes showed a decline in suicide by poisoning with drugs, although the decrease was larger among women. The fall in suicide rates among young women was almost all due to the decrease in this method. The rise in rates for men was largely due to increases in hanging and poisoning with vehicle exhaust gases, although all methods except drugs and domestic gas showed some increase. These findings indicate that suicide is an increasing problem with causes that are far from understood, so that prevention may be difficult.

Trends in suicide and unemployment in Scotland, 1976-86.

To establish whether a correlation exists between unemployment and suicide the trends in the rates of both among men in Scotland during 1976-86 were studied. Both rates showed rapid increases in the late 1970s and then much slower increases after 1982. In contrast, among women, although the rate of unemployment followed a similar pattern, there was a gradual fall in the rate of suicide. The trends in regional unemployment for men during 1971-81 were compared with the suicide rates for the period before the increase (1974-7) and the period after the rapid increase (1983-6). No association was observed between trends in suicide and unemployment when analysed by health board areas or aggregates of local government districts. These data do not support the hypothesis that the rise in unemployment is a direct cause of the rise in suicide rates among men.
