Drinking in different social contexts among white, black, and Hispanic men

This paper describes alcohol use by White, Black, and Hispanic men in eight different social settings. Data were obtained from a multi-stage probability sample of the household population of White, Black, and Hispanic adults aged 18 years and over, residing in the 48 contiguous United States. The response rate was 73 percent for Whites, 76 percent for Blacks, and 72 percent for Hispanics. Results show that Whites go more frequently and drink more frequently than Blacks and Hispanics at restaurants, in clubs or organizational meetings, and in bars. Blacks go more frequently than Whites and Hispanics to public settings such as parks, streets, and parking lots; however, the mean number of drinks consumed in these public places and the proportion of men drinking five or more drinks is higher for Hispanics than for Whites and Blacks. Other places where heavier drinking is common in all three ethnic groups are bars, taverns and cocktail lounges, and parties. In all three ethnic groups, men who are younger and those who are single go more frequently than other men to bars or public places such as streets, parks, and parking lots. Men who are younger and those who are single also have a higher rate of heavy drinking and of drunkenness than other men.     

Cigarette advertising and children's smoking: why Reg was withdrawn.

OBJECTIVE--To examine the appeal of the Embassy Regal "Reg" campaign to young people. DESIGN--Three quantitative surveys and one piece of qualitative research: (a) self completion questionnaire administered in classrooms, (b) questionnaire led interviews with children, (c) questionnaire led interviews with adults, and (d) group discussions with children and adults. SETTINGS--(a) Secondary and middle schools in England; (b) north of England, Scotland, and Wales; (c) north of England, Scotland, and Wales; and (d) Glasgow. SUBJECTS--(a) 5451 schoolchildren aged 11-15 recruited by stratified random sampling; (b) 437 children aged 5-10 recruited by quota sampling; (c) 814 adults aged 15-65 recruited by quota sampling; and (d) 12 groups of children aged 10-15, three groups of adults aged 18-24, and three groups of adults aged 35-55. RESULTS--Children were familiar with cigarette advertising and in particular the Reg campaign. Although younger children struggled to understand the creative content of the adverts, older and smoking children could understand and appreciate the humour. They considered Reg to be amusing and could relate to the type of joke used in the advert. In addition Reg''s flippant attitude towards serious issues appealed to the children. While adults aged 18-24 understood the campaign they did not identify with it, and 35-55 year olds (the campaign''s supposed target) were unappreciative of the campaign. CONCLUSIONS--The Reg campaign was getting through to children more effectively than it was to adults and held most appeal for teenagers, particularly 14-15 year old smokers. It clearly contravened the code governing tobacco advertising, which states that advertising must not appeal to children more than it does to adults, and it may have had a direct impact on teenage smoking. In view of these findings the Advertising Standards Authority''s decision to withdraw the Reg campaign seems appropriate.     

Alcohol,Binge Drinking and Associated Mental Health Problems in Young Urban Chileans

Objective

To explore the link between alcohol use, binge drinking and mental health problems in a representative sample of adolescent and young adult Chileans.

Methods

Age and sex-adjusted Odds Ratios (OR) for four mental wellbeing measures were estimated with separate conditional logistic regression models for adolescents aged 15-20 years, and young adults aged 21-25 years, using population-based estimates of alcohol use prevalence rates from the Chilean National Health Survey 2010.

Results

Sixty five per cent of adolescents and 85% of young adults reported drinking alcohol in the last year and of those 83% per cent of adolescents and 86% of young adults reported binge drinking in the previous month. Adolescents who reported binging alcohol were also more likely, compared to young adults, to report being always or almost always depressed (OR 12.97 [95% CI, 1.86-19.54]) or to feel very anxious in the last month (OR 9.37 [1.77-19.54]). Adolescent females were more likely to report poor life satisfaction in the previous year than adolescent males (OR 8.50 [1.61-15.78]), feel always or almost always depressed (OR 3.41 [1.25-9.58]). Being female was also associated with a self-reported diagnosis of depression for both age groups (adolescents, OR 4.74 [1.49-15.08] and young adults, OR 4.08 [1.65-10.05]).

Conclusion

Young people in Chile self-report a high prevalence of alcohol use, binge drinking and associated mental health problems. The harms associated with alcohol consumption need to be highlighted through evidence-based prevention programs. Health and education systems need to be strengthened to screen and support young people. Focussing on policy initiatives to limit beverage companies targeting alcohol to young people will also be needed.     

Effectiveness of motivational interviewing and physical activity on prescription on leisure exercise time in subjects suffering from mild to moderate hypertension

Background

Depression and anxiety disorders have a high disease burden and as many as 15% of young people report mental health problems. Binge drinking, which is a particularly harmful way of consuming alcohol, is common among secondary school students. The aim of this study was to examine the association between binge drinking and self-reported mental health in boys and girls aged 12 to 18 years.

Findings

This cross-sectional analysis was performed on data collected by the Community Health Service (GGD) Brabant Zuidoost, the Netherlands, in 2007. In this Youth Survey, 10 090 randomly selected adolescents aged 12 tot 18 years were each sent a letter, a questionnaire, and a user name and log-in code for if they preferred to complete the Internet version of the questionnaire. Mental health was assessed using the Mental Health Inventory (MHI-5), a short 5-item questionnaire to detect feelings of depression and anxiety. Participants were asked about current alcohol consumption, their relationship with their parents, drug use, and sociodemographic data. Corrected for confounders, binge drinking and mental health problems were associated in the 12 to 15 year old girls (OR 2.43; 95% CI 1.86-3.17, p = 0.000) and boys (OR 1.64, 95% CI 1.19-2.27, p = 0.003). The majority of the 16 to 18 year old adolescents had been binge drinking in the previous 4 weeks (69.6% boys and 56.8% girls). In this age group, boys with mental health problems were less likely to be classified as binge drinkers than were boys without mental health problems (OR 0.63, 95% CI 0.45-0.87, p = 0.005). No such association between binge drinking and mental health was found in girls of this age.

Conclusion

Girls and boys aged 12-15 years were classified as binge drinkers significantly more often when they reported poor mental health. Because binge drinking damages the brain, especially at a young age, it is important that health professionals are alert to possible binge drinking when young adolescents report mental health problems and should ask their patients about their drinking behaviour. Likewise, if youngsters under 16 present with binge drinking, they should be asked whether they are anxious or depressed.     

Health and cancer prevention: knowledge and beliefs of children and young people.

OBJECTIVE--To collect information from children and young people about their knowledge of and attitudes towards cancer and their understanding of health and health related behaviours to inform future health promotion work. DESIGN--Questionnaire survey of 15-16 year olds, and interviews with play materials with 9-10 year old children. SETTING--Six inner city, suburban, and rural schools. SUBJECTS--226 children aged 15-16 years and 100 aged 9-10 years. MAIN OUTCOME MEASURES--Knowledge about different types of cancer; beliefs about health; sources of information; quality of research data obtainable from young children about cancer and health. RESULTS--Both samples knew most about lung cancer, but there was also some knowledge of breast and skin cancer and leukaemia. Smoking, together with pollution and other environmental factors, were seen as the dominant causes of cancer. Environmental factors were mentioned more often by the inner city samples. Television and the media were the most important sources of information. Young people were more worried about unemployment than about ill health. More than half the young people did not describe their health as good, and most said they did not have a healthy lifestyle. Children were able to provide detailed information about their knowledge and understanding by using drawings as well as interviews. CONCLUSIONS--Children and young people possess considerable knowledge about cancer, especially about lung cancer and smoking, and show considerable awareness of predominant health education messages. Despite this knowledge, many lead less than healthy lifestyles. Health is not seen as the most important goal in life by many young people; the circumstances in which many children and young people live are not experienced as health promoting.     

Preventing childhood obesity by reducing consumption of carbonated drinks: cluster randomised controlled trial

Objective To determine if a school based educational programme aimed at reducing consumption of carbonated drinks can prevent excessive weight gain in children.Design Cluster randomised controlled trial.Setting Six primary schools in southwest England.Participants 644 children aged 7-11 years.Intervention Focused educational programme on nutrition over one school year.Main outcome measures Drink consumption and number of overweight and obese children.Results Consumption of carbonated drinks over three days decreased by 0.6 glasses (average glass size 250 ml) in the intervention group but increased by 0.2 glasses in the control group (mean difference 0.7, 95% confidence interval 0.1 to 1.3). At 12 months the percentage of overweight and obese children increased in the control group by 7.5%, compared with a decrease in the intervention group of 0.2% (mean difference 7.7%, 2.2% to 13.1%).Conclusion A targeted, school based education programme produced a modest reduction in the number of carbonated drinks consumed, which was associated with a reduction in the number of overweight and obese children.     

Follow up study of moderate alcohol intake and mortality among middle aged men in Shanghai,China.

OBJECTIVE: To assess the risk of death associated with various patterns of alcohol intake. DESIGN: Prospective study of mortality in relation to alcohol consumption at recruitment, with active annual follow up. SETTING: Four small, geographically defined communities in Shanghai, China. SUBJECTS: 18,244 men aged 45-64 years enrolled in a prospective study of diet and cancer during January 1986 to September 1989. MAIN OUTCOME MEASURE: All cause mortality. RESULTS: By 28 February 1995, 1198 deaths (including 498 from cancer, 269 from stroke, and 104 from ischaemic heart disease) had been identified. Compared with lifelong non-drinkers, those who consumed 1-14 drinks a week had a 19% reduction in overall mortality (relative risk 0.81; 95% confidence interval 0.70 to 0.94) after age, level of education, and cigarette smoking were adjusted for. This protective effect was not restricted to any specific type of alcoholic drink. Although light to moderate drinking (28 or fewer drinks per week) was associated with a 36% reduction in death from ischaemic heart disease (0.64; 0.41 to 0.998), it had no effect on death from stroke, which is the leading cause of death in this population. As expected, heavy drinking (29 or more drinks per week) was significantly associated with increased risks of death from cancer of the upper aerodigestive tract, hepatic cirrhosis, and stroke. CONCLUSIONS: Regular consumption of small amounts of alcohol is associated with lower overall mortality including death from ischaemic heart disease in middle aged Chinese men. The type of alcoholic drink does not affect this association.     

The Company of Drunk Youths

We conducted the third in a series of studies of the alcoholic behavior of youth in 1991 in the Moscow Oblast. We surveyed, by means of a questionnaire, 925 pupils, aged 14 to 18 years, in city schools and technical institutes. The principal purpose of the study was to determine changes in the extent of the attraction of alcohol for youth of the Moscow Oblast compared with 1984 and 1977. As the findings showed, there has been an increase in the social differentiation of drunkenness among the young: those who possessed adequate social resources less often turned to alcohol, but the group of youths who were experiencing general social hardship had started to abuse alcohol more frequently. There were also discernible negative tendencies in the pattern of alcohol consumption: young people had begun to drink more frequently outside the home and to consume stronger beverages. In risk groups, negative emotions began to assume more importance among the reasons for turning to alcohol. For any young person, social intercourse with one's peers is a necessary stage in socialization. In such a milieu, a young person not only tests the viability of adult norms conveyed to him by family and school but also works out his own rules of conduct, which, we assumed, would cause significant differences in the company in which regular use of alcohol was the norm.     

Modelling cost effectiveness of meningococcal serogroup C conjugate vaccination campaign in England and Wales

ObjectivesTo assess the cost effectiveness of a meningococcal serogroup C conjugate vaccination campaign in 0-17 year olds.DesignCost effectiveness analysis from the perspective of the healthcare provider.SettingEngland and Wales.ResultsIn 1998-9, immediately before the introduction of meningococcal C vaccination, the burden of serogroup C disease was considerable, with an estimated 1137 cases in people aged 0-17 years and at least 72 deaths. The vaccination campaign is estimated to have cost between £126m ($180m, €207m) and £241m ($343m, €395m), depending on the price of the vaccine. Under base case assumptions the cost per life year saved from the vaccination campaign is estimated to be £6259. School based vaccination was more cost effective than general practice based vaccination because of lower delivery costs. Immunisation of infants aged under 1 year was the least cost effective component of the campaign because, although this maximises the life years gained, the three dose schedule required is more expensive than other methods of delivery. Estimates of the cost per life year saved were sensitive to assumptions on the future incidence of disease and the case fatality ratio.ConclusionsMeningococcal C vaccination is likely to be more cost effective in all age groups when the incidence of disease is high. It is also more cost effective when given to children aged 1-4 (by general practitioners) and to children and young people aged 5-17 years at school than when administered to infants under 12 months of age or young people aged 16-17 years who are not at school.

What is already known on this topic

The burden of group C meningococcal disease in England and Wales in the late 1990s was considerableIn November 1999 the United Kingdom was the first country to introduce mass vaccination against group C meningococcal diseaseThere are no published economic evaluations of the vaccination campaign

What this study adds

This economic evaluation supports the introduction of the meningococcal C vaccineSchool based vaccination is more cost effective than routine vaccination of infants because delivery costs are lower and fewer doses are required     

Alcohol and energy drinks: a pilot study exploring patterns of consumption, social contexts, benefits and harms

ABSTRACT: BACKGROUND: Young people around the world are increasingly combining alcohol with energy drinks (AEDs). However, as yet, limited research has been conducted examining this issue, particularly in terms of exploring patterns of consumption, social practices and the cultural contexts of AED consumption. We sought to understand how AEDs are used and socially constructed among young people. METHODS: We conducted 25 hours of observation in a variety of pubs, bars and nightclubs, as well as in-depth interviews with ten young people who regularly consumed AEDs during a session of alcohol use. RESULTS: In this pilot study, participants were highly organised in their AED consumption practices and reported rarely altering this routine. Some young people consumed upwards of eight AEDs on a typical night, and others limited their use to between three and five AEDs to avoid unpleasant consequences, such as sleep disturbances, severe hangovers, heart palpitations and agitation. Wakefulness and increased energy were identified as the primary benefits of AEDs, with taste, reduced and increased intoxication, and sociability reported as additional benefits. Young AED users were brand sensitive and responded strongly to Red Bull imagery, as well as discounted AEDs. Finally, some young people reported substituting illicit stimulants with energy drinks. CONCLUSIONS: Combining energy drinks with alcohol is now a normalised phenomenon and an integral and ingrained feature of the night-time economy. Despite this, many young people are unaware of recommended daily limits or related harms. While some young people consume AEDs to feel less drunk (consistent with motivations for combining alcohol with illicit stimulants), others report using AEDs to facilitate intoxication. While preliminary, our findings have relevance for potential policy and regulatory approaches, as well as directions for future research.     

Brief intervention to prevent hazardous drinking in young people aged 14--15 in a high school setting (SIPS JR-HIGH): study protocol for a randomized controlled trial

ABSTRACT: BACKGROUND: Whilst the overall proportion of young people drinking alcohol in the United Kingdom has decreased in recent years, those who do drink appear to drink a larger amount, and more frequently. Early and heavy drinking by younger adolescents is a significant public health problem linked to intellectual impairment, increased risk of injuries, mental health issues, unprotected or regretted sexual experience, violence, and sometimes accidental death, which leads to high social and economic costs. This feasibility pilot trial aims to explore the feasibility of delivering brief alcohol intervention in a school setting with adolescents aged 14 and 15 and to examine the acceptability of study measures to school staff, young people and parents.Methods and designSeven schools across one geographical area in the North East of England will be recruited. Schools will be randomly allocated to one of three conditions: provision of an advice leaflet (control condition, n = 2 schools); a 30-minute brief interactive session, which combines structured advice and motivational interviewing techniques delivered by the school learning mentor (level 1 condition, n = 2 schools); and a 60-minute session involving family members delivered by the school learning mentor (level 2 condition, n = 3 schools). Participants will be year 10 school pupils (aged 14 and 15) who screen positively on a single alcohol screening question and who consent to take part in the trial. Year 10 pupils in all seven schools will be followed up at 6 and 12 months. Secondary outcome measures include the ten-question Alcohol-Use Disorders Identification Test. The EQ-5D-Y and a modified short service use questionnaire will inform the health and social resource costs for any future economic evaluation.Young people recruited into the trial will also complete a 28-day timeline follow back questionnaire at 12-month follow-up. A qualitative evaluation (with young people, school staff, learning mentors, and parents) will examine facilitators and barriers to the use of screening and brief intervention approaches in the school setting in this age group.Trial registrationTrial reference number ISRCTN07073105.     

Doctors' drinking habits and consumption of alcohol.

Alcohol consumption and drinking habits among Finnish doctors were studied as part of a survey of stress and burnout. A questionnaire containing 99 questions or groups of questions was sent to all 3496 practising doctors aged under 66 randomly selected from the registry of the Finnish Medical Association. Altogether 2671 doctors (76%) responded; this sample was representative of the Finnish medical profession. The average weekly consumption of alcohol during the past year and various aspects of drinking behaviour were assessed, and the presence or absence of symptoms and diseases often encountered among heavy drinkers and addicts was determined. The data were analysed separately for men and women, for those aged less than or equal to 40 and greater than 40, and for the men with high and low alcohol consumption and with high and low scores on the index of drinking habits. Selected variables related to work, stress, and coping were correlated with alcohol consumption and drinking behaviour. The median consumption of alcohol among male doctors was 4876 g (6.2 litres) and among female doctors 2226 g (2.8 litres) of absolute alcohol per person per year and was higher in those aged over 40. Beer was most commonly drunk by men and wine by women. Increased alcohol consumption was associated with older age, disappointment with career, heavy smoking, use of benzodiazepines, stress and burnout symptoms, suicidal thoughts, general dissatisfaction, and diseases related to alcohol. Drinking habits were heavier among doctors working in community health centres, those taking long sick leaves, younger doctors disappointed with their careers or the atmosphere at work, and older doctors immersed in their work. Alcohol consumption among doctors seems to be higher than that of the general population in Finland, and heavy drinking seems to be associated with stress and burnout.     

Electronic Cigarette Use among Irish Youth: A Cross Sectional Study of Prevalence and Associated Factors

PurposeTo examine prevalence of, and factors associated with, e-cigarette use among young people aged 16-17 in Ireland.MethodsIn 2014, a representative sample of 821 young people aged 16-17 recruited from secondary schools completed a pen and paper survey on e-cigarette use, tobacco use, and socio-demographic items.FindingsA total of 23.8% of respondents had used e-cigarettes at least once. Dual trial of tobacco and e-cigarettes was common with 69.5% of regular smokers and 30.4% of ‘ever’ smokers having tried e-cigarettes and 10.6% of current smokers using e-cigarettes regularly. 4.2% of never smokers have tried e-cigarettes. Overall, current e-cigarette use (once a month or more) was low (3.2%). Binary logistic regression conducted through generalized estimating equations (GEE) determined that controlling for other variables, current tobacco use and ‘ever’ tobacco use predicted ever e-cigarette use. Gender and school-level socioeconomic status were also independent predictors of ever e-cigarette use. Gender stood as the only predictor of on-going e-cigarette use, with males being more likely to regularly use e-cigarettes at least once a month.ConclusionsE-cigarette use among 16-17 year olds in Ireland is of note, with nearly a quarter of students having tried them. Concurrent or experimental use of e-cigarettes and tobacco is more common than sole use, while a small number have tried e-cigarettes without having tried tobacco.     

The changing pattern of alcohol consumption in England and Wales 1978-85.

An alcohol consumption survey of 926 people aged 18 or over in England and Wales was conducted by Gallup in 1985. The results were compared with those obtained in a similar survey conducted by the Office of Population Censuses and Surveys in 1978. Overall alcohol consumption remained virtually unchanged. Men showed little difference in drinking habits, except for the 18-24 age group, who seemed to be drinking less. For women mean alcohol consumption in 1985 was similar to that in 1978, but more women were not drinking at all so the mean alcohol consumption per drinker had risen. As with earlier work, this study showed that social class had little influence on alcohol consumption, while being married seemed to have a moderating effect. A variable regional pattern of alcohol intake was found. In a separate analysis under-age drinking was common among 16-17 year olds (65%). Their pattern of drinking was similar to that of other age groups, except for those over 65 years, who drank less. Change in alcohol intake in the UK over the seven years was in the middle of the range of values for other European countries. The stable UK overall consumption was perhaps due to the constant relative price of alcohol.     

Some final responses to Dr. Waugh

OBJECTIVE: To describe alcohol disorders in the general Canadian population, using as a standard indicator the CAGE questionnaire (Have you felt you needed to cut down on your drinking? Have you felt annoyed by criticism of your drinking? Have you felt guilty about drinking? Have you felt you needed a drink first thing in the morning [eye-opener]?). DESIGN: Secondary analysis of data from Canada''s Alcohol and Other Drugs Survey (CADS), a national telephone survey conducted in 1994 of a representative sample of 12,155 people aged 15 years or more. PARTICIPANTS: The CAGE questionnaire was administered to 5894 drinkers who had consumed alcohol in the 12 months before the CADS survey. MAIN OUTCOME MEASURES: Respondents with positive (2 or more affirmative responses) and negative results on the CAGE questionnaire were compared as to demographic characteristics, alcohol consumption and harmful consequences of their drinking. Independent predictors of a positive result were identified by means of logistic regression analysis. RESULTS: A total of 5.8% of CAGE-tested current drinkers had a positive result on the past-year CAGE in 1994. The proportion of respondents reporting alcohol-related problems in one or more areas of their life was 7 times greater among drinkers with a positive result on the CAGE questionnaire than among those with a negative result (66.8% v. 9.5%) (p < 0.0001). When all demographic characteristics were controlled for simultaneously, male sex, residence in the Atlantic provinces, Quebec or the Prairies, single/never married or divorced/separated marital status, and low education level were found to be independent risk factors for a positive result on the CAGE questionnaire. About 85% of the respondents with a positive result had not sought help for their drinking. Applying the estimated sensitivity and specificity of the CAGE questionnaire in detecting alcohol dependence, as per criteria of the Diagnostic and Statistical Manual, in a general US population, the authors estimated that 4.1% of Canadians had an alcohol dependence in 1994. CONCLUSION: The large proportion of current drinkers with a positive result on the CAGE questionnaire who did not seek help for their drinking underscores the need for identification and brief interventions by physicians. Further research is needed to elucidate the underlying reasons for regional differences in CAGE status.     

Peanut allergy in relation to heredity,maternal diet,and other atopic diseases: results of a questionnaire survey,skin prick testing,and food challenges.

OBJECTIVES: To determine rates of other atopic manifestations in people with peanut allergy and the prevalence of such allergy in their families. DESIGN: A survey of people with self reported peanut allergy and people referred by their general practitioner for suspected peanut allergy; survey and skin testing of 50 children with reported peanut allergy and their available first degree relatives. SUBJECTS: 622 adults and children with reported, suspected, or known peanut allergy. MAIN OUTCOME MEASURES: Prevalence of peanut allergy and other allergies in the families of people with peanut allergy. RESULTS: 622 valid completed questionnaires were returned out of the 833 questionnaires dispatched (74.7%). All forms of atopy were both more common in successive generations (P < 0.0001) and more common in maternal than paternal relatives (P < 0.0001). Peanut allergy was reported by 0.1% (3/2409) of grandparents, 0.6% (7/1213) of aunts and uncles, 1.6% (19/1218) of parents, and 6.9% (42/610) of siblings. Consumption of peanuts while pregnant or breast feeding was more common among mothers of probands aged < or = 5 years than mothers of probands aged > 5 years (P < 0.001). Age of onset correlated inversely with year of birth (r = -0.6, P < 0.001). Skin prick testing of 50 children with reported peanut allergy and their families: 7 probands (14%) had a negative result for peanut. Peanut allergy was refuted by food challenge in all those tested (5/7). No parent and 13% (5/39) of siblings had a positive result on skin prick testing for peanut. Two of these siblings had negative challenge with peanuts. The prevalence of peanut allergy in siblings is therefore 3/39 (7%). CONCLUSIONS: Peanut allergy is more common in siblings of people with peanut allergy than in the parents or the general population. Its apparently increasing prevalence may reflect a general increase of atopy, which is inherited more commonly from the mother. Peanut allergy is presenting earlier in life, possibly reflecting increased consumption of peanut by pregnant and nursing mothers.     

Influence of circadian typology on drug consumption, hazardous alcohol use, and hangover symptoms

Few studies have focused on the influence of circadian typology on drug use, and none has considered the use of illegal drugs and hazardous alcohol consumption. This study analyzes the influence of circadian typology on several types of drug consumption (habitual or sporadic), hangover symptoms (past 12 mos), and, more specifically, hazardous alcohol consumption of young adults. Five hundred seventeen university students (173 males), between 17 and 30 yrs of age, answered the Composite Scale of Morningness (CSM), the Alcohol Use Disorders Identification Test (AUDIT), and a self-referred questionnaire on drug consumption during the previous month and on the prevalence of different hangover symptoms during the previous year. Our results confirm a higher prevalence of consumption of addictive substances, both legal (nicotine and cola drinks) and illegal (cannabis and ecstasy), in evening- compared to morning- and neither-type subjects (p?相似文献   

Drinking,smoking, and illicit drug use among 15 and 16 year olds in the United Kingdom.

OBJECTIVE: To examine patterns of self reported drinking, smoking, and illicit drug use among a representative United Kingdom sample of people born in 1979. DESIGN: Cross sectional, single phase survey based on a stratified cluster sample of 70 United Kingdom secondary schools during March and April 1995. Pupils completed a 406 item standardised questionnaire under examination conditions. SETTING: United Kingdom state and private secondary schools. SUBJECTS: 7722 pupils aged 15 and 16. MAIN OUTCOME MEASURES: Reported use of alcohol, tobacco, and illicit drugs. RESULTS: Almost all the pupils had drunk alcohol, 36% (2772/7689) had smoked cigarettes in the past 30 days, and 42.3% (3264/7722) had at some time used illicit drugs, mainly cannabis. 43% (1546/3546) of boys and 38% (1529/4009) of girls had tried cannabis. Higher levels of smoking were associated with poorer school performance (20.4% (783/3840) with average performance v 44.1% (214/486) with below average performance, F = 79.06, P < 0.01). Levels of drug use in 15 and 16 year olds in 1995 were higher in Scotland than in England, Wales, or Northern Ireland. CONCLUSIONS: Drug experimentation was high among 15 and 16 year olds, and use of cannabis was particularly high among smokers. Cigarette smoking was more common among girls than boys.     

Family size and children's education in Matlab, Bangladesh

This study examines the relationship between family size and children's education in Bangladesh for two periods - 1982 with high fertility and 1996 with low fertility - using data from the Matlab Health and Demographic Surveillance System of the ICDDR,B: Centre for Health and Population Research. Children aged 8-17 years (27,448 in 1982 and 32,635 in 1996) were selected from households where the mother was aged 30-49 years and the father was the head of household. Children's education was measured in terms of completed years of schooling: at least class 1 (among 8-17 year olds), at least class 5 (among 12-17 year olds) and at least class 7 (among 15-17 year olds). After controlling for all variables in the multivariate analyses, level of children's education was not found to be associated with family size during the high fertility period. The family size-education relationship became negative during the low fertility period. In both periods children of educated mothers from wealthier households and those who lived close to primary/high schools had more education, but this socioeconomic difference reduced substantially over time. Boys had more education than girls during the high fertility period but this difference disappeared during the low fertility period. As birth rates fall and the proportion of children from small families increases an increase in children's education is to be expected.     

Aging, cancer, and cancer vaccines

ABSTRACT: World population has experienced continuous growth since 1400 A.D. Current projections show a continued increase - but a steady decline in the population growth rate - with the number expected to reach between 8 and 10.5 billion people within 40 years. The elderly population is rapidly rising: in 1950 there were 205 million people aged 60 or older, while in 2000 there were 606 million. By 2050, the global population aged 60 or over is projected to expand by more than three times, reaching nearly 2 billion people 1. Most cancers are age-related diseases: in the US, 50% of all malignancies occur in people aged 65-95. 60% of all cancers are expected to be diagnosed in elderly patients by 2020 2. Further, cancer-related mortality increases with age: 70% of all malignancy-related deaths are registered in people aged 65 years or older 3. Here we introduce the microscopic aspects of aging, the pro-inflammatory phenotype of the elderly, and the changes related to immunosenescence. Then we deal with cancer disease and its development, the difficulty of treatment administration in the geriatric population, and the importance of a comprehensive geriatric assessment. Finally, we aim to analyze the complex interactions of aging with cancer and cancer vaccinology, and the importance of this last approach as a complementary therapy to different levels of prevention and treatment. Cancer vaccines, in fact, should at present be recommended in association to a stronger cancer prevention and conventional therapies (surgery, chemotherapy, radiation therapy), both for curative and palliative intent, in order to reduce morbidity and mortality associated to cancer progression.
