The nature and long-term effects of childhood sexual abuse: a survey of adult women survivors in Britain.

The nature and long-term effects of childhood sexual abuse (CSA) were examined in 775 women survivors who responded to a survey in a women's magazine. Compared to existing research, there was a high rate of CSA involving sexual intercourse (46%), a high rate of intra-familial abuse (80%), a younger age of onset of abuse (8.5 years), and a longer duration of abuse (5.2 years). In univariate analyses, the reporting of a range of long-term psychological effects was significantly related to experience of abuse involving sexual intercourse or sexual contact, abuse perpetrated by a father or stepfather, abuse which was repeated or prolonged, presence of threats or violence, blaming of the child, saying disclosure would split the family, and a younger age of onset. In logistic and multiple regression analyses, the most important predictor variables were presence of threats or violence, and verbal coercion, followed by abuse being repeated or prolonged. It is suggested that future researchers should use a range of assessment instruments and multivariate analyses to examine the nature and long-term effects of child sexual abuse in both women and men.

Nutritional ergogenic aids: chromium, exercise, and muscle mass.

Athletes who want to develop muscle mass have sought various ways to reach this goal. We are all too familiar with the abuse of anabolic steroids and growth hormone. Given the concern for such abuses, athletes and coaches are seeking new and safer means to achieve the same end. Within the last couple of years, advertisements for chromium supplements have been prominently displayed in body-building and strength-training magazines. These supplements are purported to be a safe alternative to anabolic steroids and are said to promote an increase in muscle mass. This brief review will focus on the theoretical basis for believing that chromium supplements will increase muscle mass, and on the current research regarding the relationship of chromium and exercise.

Use of creatine and other supplements by members of civilian and military health clubs: a cross-sectional survey.

A survey was used to collect anonymous cross-sectional data on demographics, exercise habits, and use of creatine and other supplements by exercisers in civilian (C) and military (M) health clubs. M (n = 133) reported more aerobic training and less use of creatine and protein supplements than C (n = 96, p <.05). Supplement users (SU, n = 194) and nonusers (SNU, n = 35) engaged in similar frequency and duration of aerobic exercise, as well as number of resistance exercise repetitions, but SU completed more sets for each resistance exercise (x- +/- SE, 5 +/- 1) than SNU (3 +/- 1, p < or =.05). Significant (p < or =.05) associations were observed between SU and resistance training goal of strength (as opposed to endurance), as well as greater frequency of resistance training. Male gender, resistance training goal of strength, lower frequency and duration of aerobic training, and use of protein, b-hydroxy-b-methyl butyrate, and androstenedione/dehydroepiandrosterone supplements were all associated with creatine use (p <.05). For creatine users, the dose and length of creatine supplementation was 12.2 +/- 2.7 g.day-1 for 40 +/- 5 weeks. Popular magazines were the primary source of information on creatine (69%) compared to physicians (14%) or dietitians (10%, p < or =.0001). This study underscores two potential public health concerns: (a) reliance on popular media rather than allied-health professionals for information on creatine, and (b) use of creatine, a popular supplement with unknown long-term effects, in combination with other anabolic supplements of questionable efficacy and/or safety.

An interview with the president. "I'd like to see America used as a global lab".

AN INTERVIEW WITH THE PRESIDENT:"I'd Like to See America Used as a Global Lab" President Bill Clinton met with Science magazine on 6 December for a broad-ranging interview that looked at how science and technology are likely to change our world, and how he might continue to interact with the scientific community after he leaves office in January. What emerged confirms a portrait many people have painted of Clinton: a polymath who rarely resorts to the platitudes we have come to expect from politicians--especially on the topic of science. This online transcript of the conversation between Clinton and Science Editor Ellis Rubinstein contains material which could not be included in print for space reasons.

What do mothers remember about the 'back to sleep' campaign?

A campaign was launched by the Department of Health late in 1991 to advise mothers how to reduce the risk of cot death. OBJECTIVE--To investigate whether mothers remember receiving this advice, their sources of information, and the advice they were given. SETTING--Questionnaires filled in by mothers of babies born in three maternity units in East Anglia. METHOD--150 mothers of full term babies born throughout 1992 were enrolled. All of them should have received the information. They were sent a questionnaire when their baby was 6 months old. RESULTS--399 (89%) questionnaires were analysable. Sources of information were: television, 72%; magazines, 59%; midwives, 55%; health visitors, 48%; and doctors, 11%. 23% said they received no advice from a health professional about reducing the risk of cot death. Doctors, who had all been informed by the Department of Health, were surprisingly poor at passing on the information. Advice on sleeping position was remembered by 72%, overheating by 60%, and smoking by 35%. Problems in following the advice were reported by only 5% of mothers. CONCLUSIONS--The media was most influential in spreading the new advice. Basic infant care advice is not the preserve of doctors.

First-aid supplies for backpacking.

A portable first-aid kit should be carried in the backpack of campers, hikers, and anyone who expects to spend time in a remote and unoccupied area. That is the recommendation found in lay texts dealing with medical care, in backpacking books, as well as in articles appearing in popular magazines. It goes without saying that it is far better to practise safety and prevention than to have to use first aid. However, many times medical problems occur which no amount of safety and forethought could have prevented. Information in this paper indicates that hikers are generally well prepared for the health-related problems they encounter. Hikers carry diverse supplies to meet health problems but there are some basic supplies with which hikers start their long-distance sojourn. Those supplies and their usage rates are discussed, as are attitudes toward using the supplies.

Self-induced vomiting and bulimia nervosa: an undetected problem.

Six hundred and twenty women who were currently practising self-induced vomiting to control their weight were identified with the help of a women's magazine. Nineteen women (3.1%) fulfilled diagnostic criteria for anorexia nervosa. Of the remainder, 499 (83.0%) fulfilled diagnostic criteria for bulimia nervosa, a recently described eating disorder. Of these, 56.1% practised self-induced vomiting at least once daily; the mean duration of vomiting was 4.5 years. Most women were of normal body weight. On standardised measures, 68.1% of women showed pronounced psychiatric morbidity and 89% had profoundly disturbed attitudes to food and eating. 56.4% thought they definitely needed medical help, though only 30.1% had ever discussed any aspect of their eating difficulties with a doctor. This study highlights the secrecy that surrounds bulimia nervosa and suggests that it is an important undetected source of psychiatric morbidity.

Malaria prophylaxis: postal questionnaire survey of general practitioners in south east Wales.

Postal questionnaires were sent to 494 general practitioners in south east Wales asking about their experience and understanding of antimalarial prophylaxis; 293 were returned, giving a response rate of 59%. Forty eight (16%) of the respondents reported being consulted by immigrants returning home for advice about malaria prophylaxis, of whom 13 (27%) overestimated the time for which their protective immunity might last after leaving the malarious area. Two hundred and eighty respondents (96%) considered that they were responsible for advising travellers and 195 (67%) would always consult a publication before giving chemoprophylactic advice (magazines were particularly popular), but only 18 (6%) would always consult a specialist centre--the Ross Institute in eight cases (3%), a local centre in 39 (13%). Only about half of the doctors were aware of chloroquine resistance in Kenya and Thailand. Over half would withhold chloroquine in pregnancy, and many chose pyrimethamine alone or sulfadoxine-pyrimethamine as suitable chemoprophylactic drugs, though neither is still recommended by the World Health Organisation. One hundred and ninety two respondents (66%) would give advice about protective measures other than chemoprophylaxis. More must be done to encourage general practitioners to contact specialist centres and to educate them in the use of antimalarial chemoprophylactic drugs.

Dietary habits and mortality in 11,000 vegetarians and health conscious people: results of a 17 year follow up.

OBJECTIVE: To investigate the association of dietary habits with mortality in a cohort of vegetarians and other health conscious people. DESIGN: Observational study. SETTING: United Kingdom. SUBJECTS: 4336 men and 6435 women recruited through health food shops, vegetarian societies, and magazines. MAIN OUTCOME MEASURES: Mortality ratios for vegetarianism and for daily versus less than daily consumption of wholemeal bread, bran cereals, nuts or dried fruit, fresh fruit, and raw salad in relation to all cause mortality and mortality from ischaemic heart disease, cerebrovascular disease, all malignant neoplasms, lung cancer, colorectal cancer, and breast cancer. RESULTS: 2064 (19%) subjects smoked, 4627 (43%) were vegetarian, 6699 (62%) ate wholemeal bread daily, 2948 (27%) ate bran cereals daily, 4091 (38%) ate nuts or dried fruit daily, 8304 (77%) ate fresh fruit daily, and 4105 (38%) ate raw salad daily. After a mean of 16.8 years follow up there were 1343 deaths before age 80. Overall the cohort had a mortality about half that of the general population. Within the cohort, daily consumption of fresh fruit was associated with significantly reduced mortality from ischaemic heart disease (rate ratio adjusted for smoking 0.76 (95% confidence interval 0.60 to 0.97)), cerebrovascular disease (0.68 (0.47 to 0.98)), and for all causes combined (0.79 (0.70 to 0.90)). CONCLUSIONS: In this cohort of health conscious individuals, daily consumption of fresh fruit is associated with a reduced mortality from ischaemic heart disease, cerebrovascular disease, and all causes combined.

Lesbian couples: should help extend to AID?

A considerable amount of publicity has recently centred on a few Lesbian couples who have successfully obtained artificial insemination by donor (AID) in order to have a child. Advice was orginally sought on a private basis from the Journal on the following case: now the issue is public knowledge, the doctor presenting the case has agreed to open discussion, and a case conference was convened to consider it. Those taking part were: Jackie Forster, Co-editor of Sappho; lesbian feminist magazine; Carola Haigh, General Practitioner, London; Ian Kennedy, Barrister and Lecturer in Law, Kings College, London; Anthony Parsons, Gynaecology Department, Kings College Hospital, London; Jennifer Pietroni, General Practitioner, London; Gordon Price, Department of Child & Family Psychiatry, Kings College Hospital, London; Rose Robertson, from Parents Enquiry, a counselling organisation for families where there is an incidence of Homosexuality and where it is causing stress. Roger Higgs, General Practitioner and organiser of the Case Conference Series, was in the Chair.

Genomewide scan identifies susceptibility locus for dyslexia on Xq27 in an extended Dutch family.

CONTEXT: Dyslexia is a common disorder with a strong genetic component, but despite significant research effort, the aetiology is still largely unknown. OBJECTIVE: To identify loci contributing to dyslexia risk. METHODS: This was a genomewide linkage analysis in a single large family. Dutch families with at least two first degree relatives suffering from dyslexia participated in the study. Participants were recruited through an advertisement campaign in papers and magazines. The main outcome measure was linkage between genetic markers and dyslexia phenotype. RESULTS: Using parametric linkage analysis, we found strong evidence for a locus influencing dyslexia on Xq27.3 (multipoint lod = 3.68). Recombinations in two family members flanked an 8 cM region, comprising 11 currently confirmed genes. All four males carrying the risk haplotype had very low scores on the reading tests. The presentation in females was more variable, but 8/9 females carrying the risk haplotype were diagnosed dyslexic by our composite score, so we considered the putative risk allele to be dominant with reduced penetrance. Linkage was not found in an additional collection of affected sibling pairs. CONCLUSIONS: A locus influencing dyslexia risk is probably located between markers DXS1227 and DXS8091 on the X chromosome, closely situated to a locus indicated by a published genome scan of English sibling pairs. Although the locus may not be a common cause for dyslexia, the relatively small and gene poor region offers hope to identify the responsible gene.

Cancer in printing workers in Denmark.

OBJECTIVES: To study the cancer incidence in printing workers in Denmark. METHODS: The cohort of 15,534 men and 3593 women working in the printing industry in 1970 were followed up for death, emigrations, and incident cancer cases until the end of 1987. Their cancer incidence was compared with that of all economically active people in Denmark. The smoking and drinking habits reported by members of the printing trade unions at a survey in 1972 were compared with habits reported by members of other trade unions. RESULTS: Lung, bladder, renal pelvis, and primary liver cancers were in excess among the printing workers. The excess risks of lung cancer among the factory workers in newspaper and magazine production, of bladder cancer in typographers in printing establishments, of renal pelvis cancer in typographers and lithographers, and of primary liver cancer among lithographers and bookbinders exceeded those expected based on the reported smoking and drinking habits. CONCLUSION: Our results indicate, in line with a previous study from Manchester, that work with rotary letterpress printing was associated with an increased risk of lung cancer. The inconsistent results from studies on bladder cancer in printing workers may point to a risk confined to a certain subgroup. The sixfold risk of primary liver cancer in Danish lithographers warrants studies in other countries.

Knowledge of Chlamydia trachomatis genital infection and its consequences in people attending a genitourinary medicine clinic.

OBJECTIVES: To assess knowledge of Chlamydia trachomatis infections, with a comparison of knowledge of Neisseria gonorrhoeae infections. METHODS: A cross sectional survey, by self completed questionnaire, of 200 subjects attending a genitourinary outpatient clinic. RESULTS: The response rate was 82% (90 male and 73 female). 51% of men (60% of females) had heard of chlamydia. 65 (82%) were unaware of the potential consequences of infection. 66% were unaware that the disease could be asymptomatic. Significantly more men (77%) than women (60%) had heard of gonorrhoea. Most participants (68%-82%) knew little of the possible consequences of this infection, and only 26% were aware that it could be asymptomatic. Knowledge was higher regarding fertility topics. There was no correlation between knowledge and either age or socioeconomic status. However, greater knowledge was displayed by those who read health information leaflets always or often. For both men and women, the preferred source of health information was the doctor. Other popular sources were health information leaflets, women's magazines, and television. CONCLUSIONS: Barely half the participants had heard of chlamydia and gonorrhoea. Further knowledge of either infection was very poor. There are serious implications for public health. The reasons for this are unclear and require exploration before targeted health promotion. Doctors and the popular media are acceptable, and potentially effective, sources of information. Acquisition of knowledge is important, both to reduce sexual risk taking behaviour and its consequences, and to allow for informed consent for chlamydia screening programmes.

News media coverage of smoking and health is associated with changes in population rates of smoking cessation but not initiation.

OBJECTIVE: To determine whether changes in news media coverage of smoking and health issues are associated with changes in smoking behaviour in the USA. DESIGN AND MAIN OUTCOME MEASURES: Issue importance in the US news media is assessed by the number of articles published annually in major magazines indexed in The Reader's Guide to Periodical Literature. Annual incidence rates for cessation and initiation in the USA were computed from the large, representative National Health Interview Surveys (1965-1992). Patterns in cessation incidence were considered for ages 20-34 years and 35-50 years. Initiation incidence was examined for adolescents (14-17 years) and young adults (18-21 years) of both sexes. RESULTS: From 1950 to the early 1980s, the annual incidence of cessation in the USA mirrored the pattern of news media coverage of smoking and health, particularly for middle aged smokers. Cessation rates in younger adults increased considerably when second hand smoke concerns started to increase in the US population. Incidence of initiation in young adults did not start to decline until the beginning of the public health campaign against smoking in the 1960s. Among adolescents, incidence rates did not start to decline until the 1970s, after the broadcast ban on cigarette advertising. CONCLUSIONS: The level of coverage of smoking and health in the news media may play an important role in determining the rate of population smoking cessation, but not initiation. In countries where cessation has lagged, advocates should work to increase the newsworthiness of smoking and health issues.

Print media coverage of California's smokefree bar law.

OBJECTIVE: To assess the print media coverage of California's smokefree bar law in the state of California. DESIGN: Content analysis of newspaper, trade journal, and magazine items. SUBJECTS: Items regarding the smokefree bar law published seven months before and one year following the implementation of the smokefree bar law (June 1997 to December 1998). Items consisted of news articles (n = 446), opinion editorials (n = 31), editorials (n = 104), letters to the editor (n = 240), and cartoons (n = 10). MAIN OUTCOME MEASURES: Number and timing of publication of items, presence of tobacco industry arguments or public health arguments regarding law, positive, negative, and neutral views of opinion items published. RESULTS: 53% of items published concerning the smokefree bar law were news articles, 47% were opinion items. 45% of items regarding the smokefree bar law were published during the first month of implementation. The tobacco industry dominated coverage in most categories (economics, choice, enforcement, ventilation, legislation, individual quotes), except for categories public health used the most frequently (government role, tactics, organisational quotes). Anti-law editorials and letters to the editor were published more than pro-law editorials and letters. Region of the state, paper size, presence of local clean indoor air legislation, and voting on tobacco related ballot initiatives did not have an impact on the presence of opinion items. CONCLUSIONS: The tobacco industry succeeded in obtaining more coverage of the smokefree bar law, both in news items and opinion items. The tobacco industry used historical arguments of restricting freedom of choice and economic ramifications in fighting the smokefree bar law, while public health groups focused on the worker protection issue, and exposed tobacco industry tactics. Despite the skewed coverage, public health groups obtained adequate attention to their arguments to keep the law in effect.

Recall of health warnings in smokeless tobacco ads.

OBJECTIVE: To determine the effects of health warning characteristics in smokeless tobacco magazine print ads on warning recall, and the implications for current US Federal regulations. DESIGN: Subjects examined two distracter ads and one of nine randomly assigned smokeless tobacco ads varying in health warning presence, size (8 to 18 point font), and contrast (low versus high)-including no health warning. They were then interviewed about ad content using recall and recognition questions. SUBJECTS: A convenience sample of 895 English speaking males aged 16-24 years old who were intercepted at seven shopping malls throughout Massachusetts during May 2000. MAIN OUTCOME MEASURES: Proven aided recall, or recall of a health warning and correct recognition of the warning message among distracters, and false recall. RESULTS: Controlling for covariates such as education, employment/student status, and Hispanic background, proven aided recall increased significantly with font size; doubling size from 10 to 20 point font would increase recall from 63% to 76%. Although not statistically significant, recall was somewhat better for high contrast warnings. Ten per cent of the sample mistakenly recalled the warning where none existed. CONCLUSIONS: As demonstrated by substantially greater recall among ads that included health warnings over ads that had none, health warnings retained their value to consumers despite years of exposure (that can produce false recall). Larger health warnings would enhance recall, and the proposed model can be used to estimate potential recall that affects communication, perceived health risk, and behaviour modification.

Going below the line: creating transportable brands for Australia's dark market.

OBJECTIVE: To investigate non-point-of-sale cigarette marketing in Australia, one of the "darkest" markets in the world. DESIGN: Analysis of 172 tobacco industry documents. RESULTS: The tobacco industry has continued to market their products despite severe restrictions on legal marketing activity. They made careful plans to circumvent regulation well in advance. In preparation for bans, they chose and strengthened existing brands to enable their continued success in a dark market and prepared the consumer for bans by increasing their spending on below the line activities. Bans reduced the industry's effectiveness and efficiency. After bans new brand launches stopped: instead key existing brands were strengthened via alterations to the product, line extensions, and stretching loopholes in the legislation as far as possible. In line with the general trend towards integrated marketing, a range of activities have been used in combination, including guerrilla marketing, advertising in imported international magazines, altering the pack, sponsorships, brand stretching, event promotions, lifestyle premiums, and the development of corporate websites. CONCLUSIONS: The tobacco industry acknowledges that marketing restrictions have an impact, validating their continued use in tobacco control. The industry is extremely creative in circumventing these marketing restrictions, requiring tobacco marketing regulations to be informed by marketing expertise, regularly updated, and to adopt the broadest possible scope. Tobacco control advocates, particularly those communicating with young people, could learn from the creativity of the tobacco industry.
