Is household smoking status associated with expenditure on food at restaurants, alcohol, gambling and insurance? Results from the 1998-99 Household Expenditure Survey, Australia.

AIM: To examine how household expenditure on food at restaurants, alcohol, gambling and insurance vary between smoking and non-smoking households. DESIGN: Cross sectional survey of households from private dwellings, conducted by the Australian Bureau of Statistics (ABS), using a stratified multistage area sample design. SETTING: Australia, 1998-99. PARTICIPANTS: Nationally representative sample of households (n = 6892). MAIN OUTCOME MEASURES: Expenditure on meals at restaurants, alcohol, alcoholic beverages at licensed premises, gambling, and insurance. RESULTS: The odds of reporting expenditure on restaurant food and health insurance were 20% and 40% smaller for smoking than non-smoking households, respectively. The odds of reporting expenditure on alcohol (not including expenditure at licensed premises), drinking at licensed premises, and gambling were 100%, 50%, and 40% greater for smoking than for non-smoking households, respectively. CONCLUSIONS: The study suggests that smokers are more likely to engage in risky behaviour. Implementing smoking bans in licensed premises and gambling venues can provide an opportunity to reduce smoking prevalence. Quitting or cutting down smoking can provide opportunities for expenditure on other products or services, and enhance standards of living.

Review of the quality of studies on the economic effects of smoke-free policies on the hospitality industry.

OBJECTIVE: To compare the quality and funding source of studies concluding a negative economic impact of smoke-free policies in the hospitality industry to studies concluding no such negative impact. DATA SOURCES: Researchers sought all studies produced before 31 August 2002. Articles published in scientific journals were located with Medline, Science Citation Index, Social Sciences Citation Index, Current Contents, PsychInfo, Econlit, and Healthstar. Unpublished studies were located from tobacco company websites and through internet searches. STUDY SELECTION: 97 studies that made statements about economic impact were included. 93% of the studies located met the selection criteria as determined by consensus between multiple reviewers. DATA EXTRACTION: Findings and characteristics of studies (apart from funding source) were classified independently by two researchers. A third assessor blind to both the objective of the present study and to funding source also classified each study. DATA SYNTHESIS: In studies concluding a negative impact, the odds of using a subjective outcome measure was 4.0 times (95% confidence interval (CI) 1.4 to 9.6; p = 0.007) and the odds of not being peer reviewed was 20 times (95% CI 2.6 to 166.7; p = 0.004) that of studies concluding no such negative impact. All of the studies concluding a negative impact were supported by the tobacco industry. 94% of the tobacco industry supported studies concluded a negative economic impact compared to none of the non-industry supported studies. CONCLUSION: All of the best designed studies report no impact or a positive impact of smoke-free restaurant and bar laws on sales or employment. Policymakers can act to protect workers and patrons from the toxins in secondhand smoke confident in rejecting industry claims that there will be an adverse economic impact.

Smoking and financial stress.

AIM: Stress relief is commonly provided as a reason for smoking. However, it is plausible that the cost of smoking may create financial stress, particularly among the poor. The aim of the study was to examine the relationship between smoking and financial stress. DESIGN: Cross sectional survey of households from private dwellings conducted by the Australian Bureau of Statistics (ABS), using a stratified multistage area sample design. SETTING: Australia, 1998-99. PARTICIPANTS: Nationally representative sample of households (n = 6892). MAIN OUTCOME MEASURES: The outcome measures of objective financial stress were two dichotomous variables indicating whether the household had experienced any financial stress or severe financial stress in the past 12 months. RESULTS: The odds of experiencing any financial stress were 1.5 (95% confidence interval (CI) 1.3 to 1.7) times greater, and the odds of severe financial stress were twice (95% CI 1.6 to 2.5) as large for smoking households than non-smoking households. The effect of smoking on financial stress did not vary significantly across categories of income. Among smoking households, higher percentage of total household expenditure on tobacco was significantly related to financial stress. CONCLUSIONS: Given data were cross sectional, firm conclusions cannot be drawn about the causal relationship between smoking and financial stress. It is likely that they both affect each other. Undoubtedly, expenditure on tobacco will reduce available funds that could otherwise be used to ameliorate financial stress.

Impact of tobacco tax reforms on tobacco prices and tobacco use in Australia.

OBJECTIVE: To document the impact of changes to tobacco taxes on the range and price of tobacco sold during the period when the National Tobacco Campaign (NTC) was run. DATA SOURCES: Information about brand availability, pack size, and price was extracted from Australian Retail Tobacconist. A retail observational survey was undertaken to monitor actual retail prices. Data on cigarette prices, brands, packet configurations, and outlets from which they were purchased were obtained from the benchmark and three follow up population telephone surveys conducted to evaluate the NTC. METHOD: Data from the three sources were compared to see the extent to which the impact of tax changes had been offset by greater retail discounting and a more concerted effort by consumers to purchase cheaper products. RESULTS: Smokers were unable to cushion themselves from the sharp price increases that occurred during the third phase of the NTC. Both average recommended retail prices of manufactured cigarettes and average actual cigarette prices paid by smokers increased by 25% in real prices. CONCLUSION: The fall in smoking prevalence over the first two phases of the NTC was substantially greater than would be expected due to tax changes alone. The fall in smoking consumption over the first two phases was slightly less than would be expected and in the third considerably higher than would be expected.

Budesonide but not nedocromil sodium reduces exhaled nitric oxide levels in asthmatic children.

Exhaled nitric oxide (ENO) has been proposed as a marker of airway inflammation in asthma and could be useful to evaluate the response to anti-inflammatory treatment. We investigated the effect of budesonide and nedocromil sodium on ENO levels and lung function in asthmatic children. Twenty stable steroid-naïve asthmatic children were randomized in a single blind, cross-over study to receive inhaled budesonide (group A) or nedocromil sodium (group B) for 6 weeks. ENO was measured with a chemiluminescence analyser at baseline and at the end of each treatment period. Repeated-measures ANOVA was carried out. In asthmatic baseline ENO levels [mean 32.5 ppb, 95% confidence interval (CI) 26.4 to 38.7] were significantly higher compared to reference values (8.7 ppb, 95% CI 8.1 to 9.2, P<0.001). There were no treatment-order effect, no carry-over effect and in both groups the response pattern was the same: budesonide significantly lowered ENO levels from 41.0 ppb to 22.8 ppb in group A (mean, P<0.01) and from 22.6 ppb to 13.0 ppb in group B, (mean, P<0.05), while nedocromil did not reduce ENO values (from 24.4 ppb to 22.6 ppb in group B and from 22.8 ppb to 38.0 ppb in group A, mean, P = NS and P<0.01 respectively). After budesonide treatment ENO values of asthmatics were still significantly higher than in healthy children The baseline values of FEV1 and FEF(25-75) were normal in both groups and no significant changes were observed during the study. In conclusion, our study shows that budesonide, but not nedocromil sodium, significantly reduces ENO levels in stable asthmatic children even in absence of changes in the lung function.

Exhaled nitric oxide and exercise-induced bronchoconstriction in asthmatic children.

It is known that exhaled nitric oxide (ENO) is increased in asthmatic individuals, probably as an expression of airway inflammation, but no studies have been reported of ENO and exercise-induced bronchoconstriction (EIB). We assessed the effect of a treadmill exercise challenge on ENO concentration in 24 asthmatic children aged 11.2 +/- 0.4 yr (mean +/- SEM). According to the presence or absence of EIB, the children were divided into an EIB group (n = 10) and a non-EIB group (n = 14). ENO was measured with a single-breath reservoir technique. FEV(1), ENO, and heart rate were measured at baseline and 1, 6, 12, and 18 min after the end of exercise. We also measured ENO in 18 healthy control children aged 10.8 +/- 0.6 yr, of whom nine underwent an exercise challenge identical to that of the asthmatic children. After the exercise test, the mean decrease in FEV(1) was 34% in the EIB group and 5% in the non-EIB group. The EIB group had higher baseline ENO values (12.3 +/- 1.6 ppb) than the healthy children (6.1 +/- 0.2 ppb) (p < 0.01). The time course of ENO was similar in the EIB, non-EIB, and control groups, with no significant changes after exercise (p = NS). In the overall group of asthmatic children there was a significant correlation (r = 0.61, p < 0.01) between baseline (preexercise) ENO and magnitude of the maximal decrease in FEV(1) after exercise. In conclusion, our study shows that ENO levels do not change during acute airway obstruction induced by exercise challenge in asthmatic children. In addition, baseline ENO values correlate with the magnitude of postexercise bronchoconstriction, suggesting that NO may be a predictor of airway hyperresponsiveness to exercise.

A simple flow-driven method for online measurement of exhaled NO starting at the age of 4 to 5 years.

NO is increased in exhaled air of asthmatic patients, and may be used as a marker of airway inflammation. The online method is a standardized technique for measuring exhaled nitric oxide (ENO). However, this method has proven difficult for some children, who may have trouble maintaining a constant expiratory flow. The aim of this study was to validate a modified technique for online ENO measurement that utilizes a flow regulator to overcome the patient problem of having to actively maintain a constant expiratory flow. We measured ENO levels with two methods in 105 asthmatic and 10 healthy subjects, comparing the standardized (ST) single-breath method with a modified single-breath, flow-driven (FD) method. With the ST method and visual monitoring, the subjects inhaled NO-free air to TLC, and exhaled with a target flow of 50 ml/s. With the FD method, the subjects exhaled from TLC and flow was kept constant (50 ml/s) by the operator, using a flow regulator. The subjects were divided into two groups, one consisting of children aged 4 to 8 yr (n = 74) and the other of children aged 9 to 16 yr (n = 41). In the group aged 4 to 8 yr, 38 children (51%) were unable to perform the ST method, whereas only five children (7%) failed to perform the FD technique. In the group aged 9 to 16 yr, only four children (10%) were unable to perform the ST maneuver, and all successfully performed the FD maneuver. The mean concentrations of ENO in the 73 children who performed both types of maneuver were similar (36.1 +/- 3.4 [mean +/- SEM] ppb with the ST method and 33.8 +/- 3.3 ppb with the FD technique, p = NS) and were highly correlated with one another (r = 0.99, p < 0.0001). ENO values were significantly higher in steroid-naive than in steroid-treated asthmatic children. In conclusion, we describe a modified online method for measuring ENO that is simple, does not require active cooperation to maintain a constant expiratory flow, and can be easily performed by children from 4 to 5 yr of age onward.

[Assisted labor among non European community pregnant women at the Gynecology and Obstetrics Clinic of the Verona University].

BACKGROUND: The aim of this paper is to evaluate the role and the prevalence of the non-European Community pregnant women in our Institute during the period 1992-1998. The peculiarity of the female immigration in the world and particularly in Italy is stressed from the point of view of the different cultural, ethnic and religious problems of these women. METHODS: During the observed period 8972 women delivered; 434 of them came from non-European Community countries and their individual (age, country) and obstetric (parity, physiological or pathological evaluation of pregnancy, mode of delivery) data were observed. On the basis of the different countries of provenance these women have been subdivided into five groups (East Europe, North Africa and Middle East, Central Africa, Far East and Latin America). RESULTS: The percentages of preterm births (24.2% vs 23.1%), of < or = 1500 g newborns (6.9% vs 5.3%) and of caesarean sections (34.3% vs 27.7%) are higher in the non-European Community women that delivered in our Institute. In 222 (51.1%) cases the women delivered without induction of labour; while in 14.5% of cases it was induced. The length of labour and the genital conditions (episiotomy, tearing) were considered in all ethnic groups of women. CONCLUSIONS: On the basis of the literature and of the analysis of our data, some suggestions about the management of labour and delivery of non-European Community women in Italy are proposed. In particular, the problems of linguistic communication and of the hospital staff preparation in the assistance to labour and delivery are stressed.

Exhaled nitric oxide concentrations during treatment of wheezing exacerbation in infants and young children.

While it is known that exhaled nitric oxide (ENO) is increased in adults and school children with asthma exacerbation probably as an expression of disease activity, no studies have investigated whether this phenomenon also occurs in infants and young children with recurrent wheeze exacerbation. We measured ENO in 13 young children (mean age 20.2 mo) with recurrent wheeze (Group 1) during an acute episode and after 5 d of oral prednisone therapy. ENO was measured also in nine healthy control subjects (Group 2) (mean age 16.9 mo) and in six children with a first-time viral wheezy episode (Group 3) (mean age 11 mo). To measure ENO, infants inhaled NO-free air via a face mask from a reservoir and, through a nonrebreathing valve, exhaled in a collecting bag that was analyzed by chemiluminescence. To address the question of whether the levels of ENO collected in the bag are a reflection of the pulmonary airway, ENO determinations were performed in two healthy infants before and after tracheal intubation for elective surgery. During the acute episode of wheezing the mean (+/- SEM) value of ENO in children with recurrent wheeze (Group 1) was 14.1 +/- 1.8 ppb, almost threefold higher than in healthy control subjects (5.6 +/- 0.5 ppb, p < 0.001). After steroid therapy we found a mean fall of 52% in ENO (5.9 +/- 0.7 ppb, p < 0.01) compared with baseline values. ENO values measured before and after intubation in two infants were 6 ppb and 5 ppb in one child and 7 ppb and 6 ppb in the other one. The mean value of ENO of children with first-time wheeze (Group 3) was 8.3 +/- 1.3 ppb, significantly lower (p < 0.05) than the value of children with recurrent wheeze (Group 1). In conclusion, we describe a method to measure ENO in young children and show that infants with recurrent wheeze have elevated levels of ENO during exacerbation that rapidly decrease after steroid therapy. This suggests that, in these children, airway inflammation could be present at a very early stage.

The impact of smoke-free workplaces on declining cigarette consumption in Australia and the United States.

OBJECTIVES: This study estimates the contribution of smoke-free workplaces to the recent national declines in cigarette consumption in Australia and the United States. METHODS: Nineteen studies of the impact of smoke-free workplaces on workday cigarette consumption were reviewed. The number and cost of cigarettes forgone were calculated and extrapolated to a scenario in which all indoor work areas were smoke-free. RESULTS: Of the 19 studies, 18 reported declines in daily smoking rates, and 17 reported declines in smoking prevalence. Smoke-free workplaces are currently responsible for an annual reduction of some 602 million cigarettes, or 1.8% of all cigarettes that might otherwise be consumed, in Australia, and an annual reduction of 9.7 billion cigarettes (2%) in the United States. Approximately 22.3% of the 2.7 billion decrease in cigarette consumption in Australia between 1988 and 1995 can be attributed to smoke-free workplaces, as can 12.7% of the 76.5 billion decrease in the United States between 1988 and 1994. CONCLUSIONS: If workplaces were universally smoke-free, the number of cigarettes forgone annually would increase to 1.14 billion (3.4%) in Australia and 20.9 billion (4.1%) in the United States.
