Cigarette smoking by socioeconomic group, sex, and age: effects of price, income, and health publicity.

Abstract Objective: To assess effects of price, income, and health publicity on cigarette smoking by age, sex, and socioeconomic group. Design: Econometric multiple regression analysis of data on cigarette smoking from the British general household survey. Subjects: Random sample of adult population in Britain interviewed for biennial general household surveys 1972-90. Main outcome measures - Changes in cigarette consumption and prevalence of smoking. Results: Price elasticities of demand for cigarettes (percentage change in cigarette consumption for a 1% change in price) were significant at -0.5 (95% confidence interval -0.8 to -0.1) for men and -0.6 (-0.9 to -0.3) for women, were highest in socioeconomic group V (-1.0 for men and -0.9 for women), and lowest (not significantly different from zero) in socioeconomic groups I and II. The gradient in price elasticities by socioeconomic group was significant for men (F=5.6, P=0.02) and for women (F=6.1, P=0.02). Price was a significant factor in cigarette consumption by age for women in every age group and for men aged 25-34. Cigarette consumption by young men aged 16-34 increased with income. There was a significant decrease in smoking over time by women in socioeconomic groups I and II and by men in all age and social groups except socioeconomic group V attributable to health publicity. Price significantly affected smoking prevalence in socioeconomic group V (-0.6 for men and -0.5 for women) and for all women (-0.2). Conclusions: Men and women in lower socioeconomic groups are more responsive than are those in higher socioeconomic groups to changes in the price of cigarettes and less to health publicity. Women of all ages, including teenagers, appear to have been less responsive to health publicity than have men but more responsive to price. Response to health publicity decreased linearly with age. Real price increases in cigarettes could narrow differences between socioeconomic groups in smoking and the related inequalities in health, but specific measures would be necessary to ameliorate effects on the most deprived families that may include members who continue to smoke. The use of a policy to steadily increase cigarette tax is likely to help achieve the governments targets for smoking and smoking related diseases.

Low back pain of mechanical origin: randomised comparison of chiropractic and hospital outpatient treatment.

OBJECTIVE--To compare chiropractic and hospital outpatient treatment for managing low back pain of mechanical origin. DESIGN--Randomised controlled trial. Allocation to chiropractic or hospital management by minimisation to establish groups for analysis of results according to initial referral clinic, length of current episode, history, and severity of back pain. Patients were followed up for up two years. SETTING--Chiropractic and hospital outpatient clinics in 11 centres. PATIENTS--741 Patients aged 18-65 who had no contraindications to manipulation and who had not been treated within the past month. INTERVENTIONS--Treatment at the discretion of the chiropractors, who used chiropractic manipulation in most patients, or of the hospital staff, who most commonly used Maitland mobilisation or manipulation, or both. MAIN OUTCOME MEASURES--Changes in the score on the Oswestry pain disability questionnaire and in the results of tests of straight leg raising and lumbar flexion. RESULTS--Chiropractic treatment was more effective than hospital outpatient management, mainly for patients with chronic or severe back pain. A benefit of about 7% points on the Oswestry scale was seen at two years. The benefit of chiropractic treatment became more evident throughout the follow up period. Secondary outcome measures also showed that chiropractic was more beneficial. CONCLUSIONS--For patients with low back pain in whom manipulation is not contraindicated chiropractic almost certainly confers worthwhile, long term benefit in comparison with hospital outpatient management. The benefit is seen mainly in those with chronic or severe pain. Introducing chiropractic into NHS practice should be considered.

Hungry for tobacco: an analysis of the economic impact of tobacco consumption on the poor in Bangladesh

OBJECTIVE To investigate the extent of tobacco expenditures in Bangladesh and to compare those costs with potential investment in food and other essential items. DESIGN Review of available statistics and calculations based thereon. RESULTS Expenditure on tobacco, particularly cigarettes, represents a major burden for impoverished Bangladeshis. The poorest (household income of less than

118/month). Average male cigarette smokers spend more than twice as much on cigarettes as per capita expenditure on clothing, housing, health and education combined. The typical poor smoker could easily add over 500 calories to the diet of one or two children with his or her daily tobacco expenditure. An estimated 10.5 million people currently malnourished could have an adequate diet if money on tobacco were spent on food instead. The lives of 350 children could be saved each day. CONCLUSION Tobacco expenditures exacerbate the effects of poverty and cause significant deterioration in living standards among the poor. This aspect of tobacco use has been largely neglected by those working in poverty and tobacco control. Strong tobacco control measures could have immediate impact on the health of the poor by decreasing tobacco expenditures and thus significantly increasing the resources of the poor. Addressing the issue of tobacco and poverty together could make tobacco control a higher priority for poor countries.

Health promotion for adolescents in primary care: randomised controlled trial

Abstract Objective: To compare one view (oblique) and two view (oblique and craniocaudal) mammography in breast cancer screening. Design: Randomised controlled trial. Setting: Nine breast screening centres in England. Subjects: 40163 women aged 50-64 attending their first breast screening examination. Interventions: Women were randomised to have one view mammography, two view mammography, or two view mammography in which one view was read by one reader and both views were read by another. Main outcome measures: Prevalence of cancer detected, recall rates, cost per cancer detected, and marginal cost per extra cancer detected. Results: Two view mammography detected 24% more women with breast cancer (95% confidence interval 16% to 31%) than one view mammography. Prevalence of detected cancer was 6.84 with two view mammography and 5.52 per 1000 women with one view. The proportion of women recalled for assessment was 15% lower (95% confidence interval 6% to 23%) with two view (6.97%) than with one view (8.16%) mammography. The cost of two view screening was higher (pounds sterling26.46 compared with pounds sterling22.00 per examination) but the average cost per cancer detected was similar (pounds sterling5330 compared with pounds sterling5310) and the marginal cost per extra cancer detected with two views was similar to the average cost (pounds sterling5400). Conclusion: Two view mammography is medically more effective than one view; it detects more cancers and reduces recall rates; it is also similarly cost effective financially.

Price and cigarette consumption in Europe

STUDY OBJECTIVE--To compare a community support scheme using care attendants with standard aftercare for their effects on independence and morale of elderly patients discharged from hospital and on their use of health and social services. DESIGN--Randomised controlled study of cohort of patients over 75 discharged to their own homes. SETTING--District general hospital and community. PATIENTS--Total of 903 patients (mean age 82, 25% over 85). INTERVENTIONS--Total of 464 patients received support from care attendants on first day at home and for up to 12 hours a week for two weeks. Support comprised practical care, help with rehabilitation, and organising social help. The remaining 439 patients received standard aftercare. END POINT--Difference between two groups of 7% in hospital readmission rates or one point on activities of daily living scale (power 80%, significance level 5%). MEASUREMENTS AND MAIN RESULTS--Three months after the initial discharge 763 patients were interviewed (84%). There were no significant differences between the two groups in physical independence (activities of daily living scale), in measures of morale (Philadelphia scale), or in death rates. Hospital readmission rates within 18 months of discharge, however, were significantly higher in the control group and they spent more days in hospital (mean; control group 30.6 days, support group 17.1 days; p = 0.014). Of the patients living alone who were followed up for 18 months 21 (15%) receiving standard aftercare were readmitted more than twice compared with 6 (5%) supported by care attendants (p less than 0.01). CONCLUSIONS--If the findings are confirmed, and the policy extended to all patients over the age of 75 living alone, an average health district might expect either to save about 23 hospital beds at a net annual saving of about pounds 220,000 in the short term or to increase available beds by this number.

Adolescent smokers seen in general practice : health, lifestyle, physical measurements, and response to antismoking advice

Abstract Objectives: To evaluate the effectiveness of inviting teenagers to general practice consultations to discuss health behaviour concerns and appropriate follow up care. Design: Randomised controlled trial, with participants randomised to a consultation (intervention) or usual care (control). Questionnaires completed at baseline, 3 months, and 12 months. Setting: Eight general practices in Hertfordshire, England. Participants: 1516 teenagers aged 14-15 years. Intervention: Consultations with practice nurses to discuss health concerns and develop plans for healthier lifestyles. Main outcome measures: Mental and physical health, “stage of change” for health related behaviour, and use of health services. Results: At baseline 970 teenagers completed questionnaires; 23% smoked, 35% had been drunk in the previous three months, 64% considered they ate unhealthily, 39% took little exercise, and 36% had possible depression. 41% (304) of teenagers invited attended for a consultation; over one third (112) were offered follow up care. More intervention group teenagers reported positive movement in stage of change for diet and exercise and in at least one of four behaviours (diet, exercise, smoking, drinking alcohol) at 3 months (41% v 31%, P<0.01), but this did not persist at 12 months. There was marginally more positive change in actual behaviour by intervention teenagers at 3 months (16% v 12%, P=0.06). Recognition of possible depression resulted in improved mental health outcomes at 3 and 12 months. 97% of attenders said they would recommend the intervention to a friend. Conclusions: Change in behaviour was slight but encouraging, and the intervention was well received and relatively cheap.

Medical, surgical, and health outcomes of gastrostomy feeding.

Objective: To analyse the variation in demand for tobacco according to price of cigarettes across the European region. Design: Cross-sectional study. Setting: All the 52 countries of the European region. Participants: For each European country, data were collected on annual per adult cigarette consumption (2000), smoking prevalence (most recent), retail price of a pack of local and foreign brand cigarettes (around 2000), the gross domestic product adjusted by purchasing power parities, and the adult population (2000). Main outcome measure: Price elasticity of demand for cigarettes (that is, the change in cigarette consumption according to a change in tobacco price) across all the European countries, estimated by double-log multiple linear regression. Results: Controlling for male to female prevalence ratio, price elasticities for consumption were −0.46 (95% confidence interval (CI) −0.74 to −0.17) and −0.74 (95% CI −1.13 to −0.35) for local and foreign brand, respectively. The inverse relation between cigarette price and consumption was stronger in countries not in the European Union (price elasticity for foreign brand cigarettes of −0.8) as compared to European Union countries (price elasticity of −0.4). Conclusions: The result that, on average, in Europe smoking consumption decreases 5–7% for a 10% increase in the real price of cigarettes strongly supports an inverse association between price and cigarette smoking.

Pricing Policies And Control of Tobacco in Europe (PPACTE) project: cross-national comparison of smoking prevalence in 18 European countries

OBJECTIVE--To compare physical, lifestyle, and health characteristics of adolescent smokers and non-smokers and their initial response to anti-smoking counselling. DESIGN--Adolescents aged 13, 15, and 17 years were identified from age-sex registers and invited by letter for a general practice health check. SETTING--Three general practices in the MRC general practice research framework. MAIN OUTCOME MEASURES--Blood pressure, body mass index, saliva cotinine concentration, peak flow rate, alcohol consumption, exercise, duration of sleep, and stated persistent health problems. RESULTS--73% of the adolescents (491) attended for the health check. A total of 68 (14%) were regular smokers. By age 17 those who smoked regularly had a significantly lower systolic blood pressure than those who had never smoked regularly (by 6 mm Hg; p = 0.025) despite a significantly higher body mass index (by 1.5; p <0.001) [corrected]. Cotinine concentrations increased with smoking exposure, from 0.7 ng/ml when no family member smoked to 155 ng/ml in active smokers of six or more cigarettes a week. Significantly more regular smokers than never regular smokers drank greater than or equal to 8 g alcohol a day (chi 2 = 15.2 adjusted for age and sex p less than 0.001); regular smokers exercised less (1.0 hrs/week in boys and 0.8 hrs/week in girls v 3.4 hrs/week in boys and 2.2 hrs/week in girls; p less than 0.001) and slept less (8.0 hrs/night v 8.5 hrs/night at age 17; p less than 0.005). Persistent health problems, mostly asthma or allergic symptoms, were reported by 25% (17/68) of the smokers and 16% (60/381) of the non-smokers. Of the smokers given counselling, 60% (26/43) made an agreement with the practice doctor or nurse to give up smoking. CONCLUSION--General practice is an appropriate setting for adolescents to receive advice on healthy lifestyle, which should not focus solely on smoking.
