A Clustered Randomized Controlled Trial to Reduce Secondhand Smoke Exposure Among Nonsmoking Pregnant Women in Sichuan Province, China.

INTRODUCTION: Nonsmoking pregnant women in China have significant exposure to secondhand smoke (SHS). Few interventions have focused on pregnant women reducing their SHS exposure. METHODS: This clustered randomized controlled trial, conducted at eight hospitals in Sichuan, China, compared a prenatal health education intervention with usual clinical care as a control. The primary outcome was self-reported "no SHS exposure" before and 3 months after birth. The intervention consisted of three large group educational sessions, standardized clinician advice, brief monthly follow-up calls, and educational materials and resources. A random sample of participants was biochemically validated before birth with hair nicotine, a long-term biomarker of smoke exposure. RESULTS: Overall, 1181 participants were randomized to intervention (n = 526) and control (n = 655) groups. More participants in the intervention group than the control group reported no SHS exposure 3 months after birth (Total: 77.9% vs. 52.6%, P < .001; Home: 81.2% vs. 53.3%, P < .001). The intervention group also had greater changes in improved smoke-free homes and SHS knowledge and attitudes. Controlling for covariates, the intervention group was less likely to report SHS exposure than the control group (Total: OR = 0.47, 95% CI = 0.31 to 0.71; Home: OR = 0.33, 95% CI = 0.21 to 0.53), and this effect was sustained 3 months after birth. The adjusted log concentration of hair nicotine for the intervention group decreased by 0.28 log µg/g more than the control group. CONCLUSIONS: Our smoke-free health education intervention for nonsmoking pregnant women significantly reduced SHS exposure before and after birth. This intervention model can become part of a standard protocol for the care of pregnant women in hospital settings.

China has raised the tax on cigarettes: what's next?

The Chinese government raised tobacco tax on 10th May 2015, 10 years after the ratification of the WHO Framework Convention on tobacco control. The increase in the resulting tax rate as a percentage of the retail price from 49% to 56% is still relatively low compared to the WHO-recommended benchmark, which is about 70% of the retail price. Therefore, ample room remains for the Chinese government to further increase the tax on cigarettes.

The healthcare costs of secondhand smoke exposure in rural China.

OBJECTIVE: The goal of this study was to assess the healthcare costs attributable to secondhand smoke (SHS) exposure among non-smoking adults (age ≥ 19) in rural China. METHODS: We analysed data from the 2011 National Rural Household Survey which was conducted among adults in five provinces and one municipality in China (N=12,397). Respondents reported their smoking status, health conditions and healthcare expenditures. Relative risks were obtained from published sources. Healthcare costs included annual outpatient and inpatient hospitalisation expenditures for five SHS-related diseases: asthma, breast cancer (female only), heart disease, lung cancer and tuberculosis. SHS-attributable healthcare costs were estimated using a prevalence-based annual cost approach. FINDINGS: The total healthcare costs of SHS exposure in rural China amounted to $1.2 billion in 2011, including $559 million for outpatient visits and $612.4 million for inpatient hospitalisations. The healthcare costs for women and men were $877.1 million and $294.3 million, respectively. Heart disease was the most costly condition for both women ($701.7 million) and men ($180.6 million). The total healthcare costs of SHS exposure in rural China accounted to 0.3% of China's national healthcare expenditures in 2011. Over one-fifth of the total healthcare costs of SHS exposure in rural China were paid by health insurance. The out-of-pocket expenditures per person accounted for almost half (47%) of their daily income. CONCLUSIONS: The adverse health effects of SHS exposure result in a large economic burden in China. Tobacco control policies that reduce SHS exposure could have an impact on reducing healthcare costs in China.

The heterogeneous effects of cigarette prices on brand choice in China: implications for tobacco control policy.

BACKGROUND: China has long kept its tobacco taxes below international standards. The Chinese government has cited two rationales against raising tobacco tax, namely, the unfair burden it places on low-income smokers and the ability of consumers to switch to cheaper brands. OBJECTIVE: This study examines how different socioeconomic subgroups of Chinese smokers switch brands in response to cigarette price changes. METHODS: We model smokers' choice of cigarette tier as a function of tier-specific prices. We examine heterogeneous responses to prices by estimating mixed logit models for different income and education subgroups that allow for random variation in smokers' preferences. We use data from three waves of the longitudinal International Tobacco Control China Survey, collected in six large Chinese cities between 2006 and 2009. FINDINGS: Low-income and less educated smokers are considerably more likely to switch tiers (including both up-trading and down-trading) than are their high-socioeconomic status (SES) counterparts. For those in the second-to-lowest tier, a ¥1 ($0.16, or roughly 25%) rise in prices increases the likelihood of switching tiers by 5.6% points for low-income smokers and 7.2% points for less educated smokers, compared to 1.6% and 3.0% points for the corresponding high-SES groups. Low-income and less educated groups are also more likely to trade down compared to their high-SES counterparts. CONCLUSIONS: Only a small percentage of low-income and less educated Chinese smokers switched to cheaper brands in response to price increases. Hence, the concern of the Chinese government that a cigarette tax increase will lead to large-scale brand switching is not supported by this study.

The impact of smoke-free legislation on reducing exposure to secondhand smoke: differences across gender and socioeconomic groups.

BACKGROUND: On 11 January 2009, Taiwan expanded its smoke-free legislation to all indoor public places and workplaces. This study examined the impact of this policy on secondhand smoke (SHS) exposure in adult non-smokers, across gender and socioeconomic status groups (SES). METHODS: An annual sample of about 13,000-14,000 non-smokers was drawn from cross-sectional nationwide data of Taiwan Adult Tobacco Behavior Surveys during 2005-2011. Logistic regressions were used to analyse the aggregate data to estimate the association between the 2009 smoke-free legislation and SHS exposures in homes and workplaces. Interaction terms were used to examine the impact of the 2009 smoke-free policy on reducing differences in SHS exposure across gender, education and income groups. RESULTS: The 2009 policy reduced the odds of SHS exposure in homes in 2009 (OR=0.76, 95% CI 0.68 to 0.84) and in workplaces (year 2009: OR=0.49, 95% CI 0.39 to 0.62; year 2010: OR=0.79, 95% CI 0.66 to 0.95). The model with interaction terms showed that men were more likely than women to be exposed to workplace SHS (OR=2.02, 95% CI 1.80 to 2.27) but were less likely to be exposed to home SHS (OR=0.79, 95% CI 0.73 to 0.86). SHS exposure in homes was significantly related to lower socioeconomic status, but the 2009 smoke-free policy reduced the difference in SHS exposure across education levels. CONCLUSIONS: The 2009 smoke-free policy reduced the SHS exposure for non-smokers. However, this impact on home SHS did not persist after 2009, and the effect of protection was unequal across gender and SES groups. Thus, further enforcement of smoking restrictions would be needed to reduce the risk of SHS exposure and improve protection against SHS risk among parts of the population with lower socioeconomic status.

The effect of cigarette prices on brand-switching in China: a longitudinal analysis of data from the ITC China Survey.

BACKGROUND: Recent studies have found that Chinese smokers are relatively unresponsive to cigarette prices. As the Chinese government contemplates higher tobacco taxes, it is important to understand the reasons for this low response. One possible explanation is that smokers buffer themselves from rising cigarette prices by switching to cheaper cigarette brands. OBJECTIVE: This study examines how cigarette prices influence consumers' choices of cigarette brands in China. METHODS: This study uses panel data from the first three waves of the International Tobacco Control China Survey, drawn from six large cities in China and collected between 2006 and 2009. The study sample includes 3477 smokers who are present in at least two waves (8552 person-years). Cigarette brands are sorted by price into four tiers, using excise tax categories to determine the cut-off for each tier. The analysis relies on a conditional logit model to identify the relationship between price and brand choice. FINDINGS: Overall, 38% of smokers switched price tiers from one wave to the next. A ¥1 change in the price of cigarettes alters the tier choice of 4-7% of smokers. Restricting the sample to those who chose each given tier at baseline, a ¥1 increase in price in a given tier would decrease the share choosing that tier by 4% for Tier 1 and 1-2% for Tiers 2 and 3. CONCLUSIONS: China's large price spread across cigarette brands appears to alter the brand selection of some consumers, especially smokers of cheaper brands. Tobacco pricing and tax policy can influence consumers' incentives to switch brands. In particular, whereas ad valorem taxes in a tiered pricing system like China's encourage trading down, specific excise taxes discourage the practice.

Secondhand smoke exposure at home in rural China.

PURPOSE: This study estimated secondhand smoke (SHS) exposure at home among nonsmoking children (age 0-18) and adults (age ≥ 19) in rural China, and examined associated socio-demographic factors. METHODS: A total of 5,442 nonsmokers (including 1,456 children and 3,986 adults) living in six rural areas in China were interviewed in person. The standardized questionnaire obtained information on their demographic characteristics and SHS exposure at home. Differences in SHS exposure were assessed by use of the chi-squared test. Logistic regression analysis was used to examine the associated factors. RESULTS: Occurrence of SHS exposure at home among nonsmoking children and adults was 68.0 and 59.3%, respectively. Logistic regression analysis found that children living in households with married, low-education, and low-income heads of household, and those who resided in the Qinghai province of China were more likely to be exposed to SHS. Among adults, those who were female, aged 19-34, single, low-education, and low-income, and those who lived in Qinghai province were more likely to be exposed to SHS at home. CONCLUSIONS: Our findings of substantial SHS exposure at home in rural China emphasize the importance of implementing interventions to reduce SHS exposure among this population.

Can increases in the cigarette tax rate be linked to cigarette retail prices? Solving mysteries related to the cigarette pricing mechanism in China.

OBJECTIVE: To explain China's cigarette pricing mechanism and the role of the Chinese State Tobacco Monopoly Administration (STMA) on cigarette pricing and taxation. METHODS: Published government tobacco tax documentation and statistics published by the Chinese STMA are used to analyse the interrelations among industry profits, taxes and retail price of cigarettes in China. RESULTS: The 2009 excise tax increase on cigarettes in China has not translated into higher retail prices because the Chinese STMA used its policy authority to ensure that retail cigarette prices did not change. The government tax increase is being collected at both the producer and wholesale levels. As a result, the 2009 excise tax increase in China has resulted in higher tax revenue for the government and lower profits for the tobacco industry, with no increase in the retail price of cigarettes for consumers. CONCLUSIONS: Numerous studies have found that taxation is one of the most effective policy instruments for tobacco control. However, these findings come from countries that have market economies where market forces determine prices and influence how cigarette taxes are passed to the consumers in retail prices. China's tobacco industry is not a market economy; therefore, non-market forces and the current Chinese tobacco monopoly system determine cigarette prices. The result is that tax increases do not necessarily get passed on to the retail price.

Economic costs attributable to smoking in China: update and an 8-year comparison, 2000-2008.

OBJECTIVE: To estimate the health-related economic costs attributable to smoking in China for persons aged 35 and older in 2003 and in 2008 and to compare these costs with the respective results from 2000. METHODS: A prevalence-based, disease-specific approach was used to estimate smoking-attributable direct and indirect economic costs. The primary data source was the 2003 and 2008 China National Health Services Survey, which contains individual participant's smoking status, healthcare use and expenditures. RESULTS: The total economic cost of smoking in China amounted to $17.1 billion in 2003 and $28.9 billion in 2008 (both measured in 2008 constant US$). Direct smoking-attributable healthcare costs in 2003 and 2008 were $4.2 billion and $6.2 billion, respectively. Indirect economic costs in 2003 and 2008 were $12.9 billion and $22.7 billion, respectively. Compared to 2000, the direct costs of smoking rose by 72% in 2003 and 154% in 2008, while the indirect costs of smoking rose by 170% in 2003 and 376% in 2008. CONCLUSIONS: The economic burden of cigarette smoking has increased substantially in China during the past decade and is expected to continue to increase as the national economy and the price of healthcare services grow. Stronger intervention measures against smoking should be taken without delay to reduce the health and financial losses caused by smoking.

Effect of media campaigns and smoke-free ordinance on public awareness and secondhand smoke exposure in Taiwan.

This study evaluated the effect of Taiwan's smoke-free ordinance and media campaigns on public awareness and secondhand smoke exposure. The authors conducted 3 waves of research--in July 2008 (before media campaigns), in December 2008 (during media campaigns), and in March 2009 (3 months after implementation of the smoke-free law). National representative samples of 1074, 1084, and 1094 people, respectively, were interviewed successfully by telephone in the 3 surveys. The results showed that general awareness of smoke-free workplace legislation rose dramatically from 28.5% in July 2008 to 87.6% in December 2008 to 93.6% in March 2009. Exposure to secondhand smoke in the workplace fell from 28.5% in July 2008 to 24.9% in December 2008 to 7.3% in March 2009, and household secondhand smoke exposure decreased from 36.8% to 34.3% to 21.3%, respectively, during the same period. Multivariate analyses results indicated that media campaigns, smoke-free ordinance implementation, having higher education, and having higher income were associated with more awareness of the smoke-free workplace legislation. In addition, smoke-free ordinance implementation, being female, having higher education, and having higher income were associated with less likelihood of reporting secondhand smoke exposure in the workplace. In conclusion, smoke-free ordinance implementation and media campaigns were effective in raising public awareness of the new law and reducing secondhand smoke exposure in workplaces, in public places, and at home.

Recent tobacco tax rate adjustment and its potential impact on tobacco control in China.

OBJECTIVES: To compare the new tobacco tax structure effective from May 2009 with the tax structure before May 2009 and to analyse its potential impact. METHODS: Published government statistics and estimated price elasticities of the demand for cigarettes are used to estimate the impact of the new tax rate adjustment on cigarette consumption and population health. RESULTS: The new adjustment increased the tax rate by 11.7% points at the producer price level. Converting this 11.7% point increase to the retail price level would mean an increase of 3.4% points in the retail price tax rate. Thus, China's new cigarette tax rate at the retail level would be 43.4% instead of the previous 40%. CONCLUSIONS: The primary motivation for the recent Chinese government tobacco tax adjustment is to raise additional government revenue. Because the additional ad valorem tax has not yet been transferred to smokers, there is no public health benefit. It is hoped that the Chinese government will pass along these taxes to the retail price level, which would result in between 640,000 and two million smokers quitting smoking and between 210,000 and 700,000 quitters avoiding smoking-related premature death.

The role of taxation in tobacco control and its potential economic impact in China.

OBJECTIVES: To identify key economic issues involved in raising the tobacco tax and to recommend possible options for tobacco tax reform in China. METHODS: Estimated price elasticities of the demand for cigarettes, prevalence data and epidemiology are used to estimate the impact of a tobacco tax increase on cigarette consumption, government tax revenue, lives saved, employment and revenue loss in the cigarette industry and tobacco farming. RESULTS: The recent Chinese tax adjustment, if passed along to the retail price, would reduce the number of smokers by 630,000 saving 210,000 lives, at a price elasticity of -0.15. A tax increase of 1 RMB (or US$0.13) per pack of cigarettes would increase the Chinese government's tax revenue by 129 billion RMB (US 17.2 billion), decrease consumption by 3.0 billion packs of cigarettes, reduce the number of smokers by 3.42 million and save 1.14 million lives. CONCLUSION: The empirical economic analysis and tax simulation results clearly indicate that increasing the tobacco tax in China is the most cost-effective instrument for tobacco control.

Quit smoking advice from health professionals in Taiwan: the role of funding policy and smoker socioeconomic status.

OBJECTIVES: In 2002, Taiwan launched a program to encourage doctors to provide brief cessation counselling to their patients during routine outpatient visits. This study is to compare and analyse the annual prevalence rate of receiving advice to quit smoking from health professionals before (2004) and after (2005, 2006) the increase in funding and the withdrawal of additional funding (2007). METHODS: We analysed pooled data from 2004 to 2007 Taiwan Adult Tobacco Survey, an annual random digit dialling telephone survey, to estimate the prevalence of receiving quit advice among ever smokers across these years. Smoking characteristics and the socioeconomic factors of smokers associated with receipt of advice to quit smoking were also examined. RESULTS: The prevalence rate of receiving quit advice increased from 21.1% in 2004 to 28.2% in 2006, and then decreased slightly to 27.6% in 2007 after the funds were cut. Multivariate analyses results indicated that increasing financing for smoking cessation services in 2005, being male, older, a daily cigarette user, having previously attempted to quit, perceiving oneself as having poor health and being aware of the benefits of smoking cessation services were significantly positively associated with receiving quit advice from health professionals. In contrast, smokers who were younger, female and occasional cigarette users were less likely to receive quit advice. Also, smokers with socioeconomic disadvantages were not less likely to receive quit advice. CONCLUSIONS: During the period of increased funding for smoking cessation services, the rates of receiving quit advice increased among all smokers and across different socioeconomic groups.

Exposure to secondhand smoke and associated factors among non-smoking pregnant women with smoking husbands in Sichuan province, China.

BACKGROUND: Secondhand smoke (SHS) exposure harms pregnant women and the fetus. China has the world's largest number of smokers and a high male smoking prevalence rate. OBJECTIVE: To compare exposure to SHS among rural and urban Chinese non-smoking pregnant women with smoking husbands, and analyze factors associated with the level of SHS exposure and hair nicotine concentration. SETTING: Sichuan province, China. POPULATION: In all 1,181 non-smoking pregnant women with smoking husbands recruited from eight district/county Women and Children's hospitals. METHODS: The women completed a questionnaire in April and May 2008. Based on systematic sampling, 186 pregnant women were selected for sampling the nicotine concentration in their hair. Ordinal logistic regression analysis was conducted to examine correlates with self-reported SHS exposure (total and at home); linear regression was conducted for the sub-sample of hair nicotine concentrations. MAIN OUTCOME MEASURES: Secondhand smoking exposure rates, hair nicotine levels. RESULTS: About 75.1% of the non-smoking pregnant women with smoking husbands reported regular SHS exposure. The major source of exposure was through their husband. In the multivariate analysis, the risk of greater SHS exposure (total and at home) and hair nicotine concentration was increased for women who were rural, had a husband with greater cigarette consumption, less knowledge about SHS, less negative attitudes about SHS, and no smoke-free home rules. CONCLUSIONS: The high prevalence rate of SHS exposure suggests that it is important for non-smoking pregnant women, especially rural women, to establish smoke-free home rules and increase knowledge and negative attitudes towards SHS.

Effects of global and domestic tobacco control policies on cigarette consumption per capita: an evaluation using monthly data in China.

INTRODUCTION: China consumes 44% of the world's cigarettes. Robust tobacco control measures are needed to contain the trend of increasing cigarette consumption. This paper examines the effectiveness of policy interventions introduced in China on reducing the country's tobacco use. METHODS: The paper uses data on China's monthly cigarette consumption per capita from January 2000 to June 2017 to estimate the impact of specific policies on China's tobacco consumption. Tobacco consumption is calculated from monthly sales data from the China National Tobacco Corporation and demographic data from the China National Bureau of Statistics. The policies studied include the WHO Framework Convention on Tobacco Control (FCTC), national tobacco-related policy changes and two tobacco tax increases implemented in China during the study period. Segmented regression analysis is used to estimate the immediate effects of the policies studied and changes in the time trends resulted from these policy changes. FINDINGS: The impact of national policy changes in China is almost 20 times greater than the impact of the WHO FCTC treaty itself, and national policy changes in tobacco control are a determining factor in reversing the trend of increasing tobacco consumption in China. The 2015 tax increase, which raised retail cigarette prices, produced both immediate and trend effects, with a total incremental effect 7.8 times that of the 2009 tax increase, which did not result in higher cigarette prices for the consumer. INTERPRETATIONS: Translating global tobacco control policies into domestic policies will generate a much greater impact on reducing average cigarette consumption, and tobacco taxes that are reflected in the retail prices of cigarettes will be more effective in reducing cigarette consumption.

Chinese physicians and their smoking knowledge, attitudes, and practices.

BACKGROUND: China has the most smokers among the world's nations. Physicians play a key role in smoking cessation, but little is known about Chinese physicians and smoking. METHODS: This 2004 clustered randomized survey of 3552 hospital-based physicians from six Chinese cities measured smoking attitudes, knowledge, personal behavior, and cessation practices for patients. Descriptive statistics and multivariate analysis of factors associated with asking about or advising against smoking were conducted in 2005 and 2006. RESULTS: Smoking prevalence was 23% among all Chinese physicians, 41% for men and 1% for women. Only 30% report good implementation of smoke-free workplace policies and 37% of current smokers have smoked in front of their patients. Although 64% usually advise smokers to quit, only 48% usually ask about smoking status, and 29% believe most smokers will follow their cessation advice. Less than 7% set quit dates or use pharmacotherapy when helping smokers quit. Although 95% and 89%, respectively, know that active or passive smoking causes lung cancer, only 66% and 53%, respectively, know that active or passive smoking causes heart disease. Physicians were significantly more likely to ask about or advise against smoking if they believed that counseling about health harms helps smokers quit and that most smokers would follow smoking-cessation advice. CONCLUSIONS: Physician smoking cessation, smoke-free workplaces, and education on smoking-cessation techniques need to be increased among Chinese physicians. Strengthening counseling skills may result in more Chinese physicians helping smoking patients to quit. These improvements can help reduce the Chinese and worldwide health burden from smoking.

Disease burden of adult lung cancer and ischaemic heart disease from passive tobacco smoking in China.

OBJECTIVE: To address the health hazards tobacco smoking imposes upon non-smokers in China, this paper estimates the burden of diseases in adults from passive tobacco smoking for two major diseases--lung cancer and ischaemic heart disease (IHD). METHODS: The disease burden was estimated in terms of both premature mortality and disability adjusted life years (DALYs), a measure that accounts for both the age at death and the severity of the morbidity. RESULTS: Passive smoking caused more than 22,000 lung cancer deaths in 2002 according to these estimates. When the toll of disability is added to that of mortality, passive smoking was responsible for the loss of nearly 230,000 years of healthy life from lung cancer. Using the evidence from other countries that links IHD to passive smoking, we estimated that approximately 33,800 IHD deaths could be attributable to passive smoking in China in 2002. Passive smoking is also responsible for the loss of more than one quarter of a million years of healthy life from IHD. Although most of the disease burden caused by active smoking occurs among men, women bear nearly 80% of the total burden from passive smoking. The number of deaths among women caused by passive smoking is about two-thirds of that caused by smoking for the two diseases we examined. CONCLUSION: Even without considering the passive smoking risks for other diseases and among children that have been documented in other countries, passive smoking poses serious health hazards for non-smokers, especially for adult female non-smokers in China, adding more urgency to the need for measures to be taken immediately to protect the health of non-smokers and curb the nation's tobacco epidemic.

Economic Burden for Lung Cancer Survivors in Urban China.

BACKGROUND: With the rapid increase in the incidence and mortality of lung cancer, a growing number of lung cancer patients and their families are faced with a tremendous economic burden because of the high cost of treatment in China. This study was conducted to estimate the economic burden and patient responsibility of lung cancer patients and the impact of this burden on family income. METHODS: This study uses data from a retrospective questionnaire survey conducted in 10 communities in urban China and includes 195 surviving lung cancer patients diagnosed over the previous five years. The calculation of direct economic burden included both direct medical and direct nonmedical costs. Indirect costs were calculated using the human capital approach, which measures the productivity lost for both patients and family caregivers. The price index was applied for the cost calculation. RESULTS: The average economic burden from lung cancer was $43,336 per patient, of which the direct cost per capita was $42,540 (98.16%) and the indirect cost per capita was $795 (1.84%). Of the total direct medical costs, 35.66% was paid by the insurer and 9.84% was not covered by insurance. The economic burden for diagnosed lung cancer patients in the first year following diagnosis was $30,277 per capita, which accounted for 171% of the household annual income, a percentage that fell to 107% after subtracting the compensation from medical insurance. CONCLUSIONS: The economic burden for lung cancer patients is substantial in the urban areas of China, and an effective control strategy to lower the cost is urgently needed.

Attention-deficit/hyperactivity disorder in children: excess costs before and after initial diagnosis and treatment cost differences by ethnicity.

OBJECTIVES: To estimate the excess costs for children in the years surrounding initial diagnosis of attention-deficit/hyperactivity disorder (ADHD) and to estimate differences in treatment costs by ethnicity. DESIGN: We identified children diagnosed with ADHD and estimated their health service costs in the 2 years before and 2 years after initial diagnosis of ADHD. Costs were compared with those for children without ADHD. We adjusted for age, sex, ethnicity, pharmacy co-pay, estimated family income, coexisting mental health disorders, and chronic medical conditions. SETTING: Nonprofit, integrated health care delivery system in northern California from January 1, 1996, to December 31, 2004. PARTICIPANTS: Children aged 2 to 10 years with (n = 3122) and without (n = 15 899) ADHD. Main Exposure Attention-deficit/hyperactivity disorder. MAIN OUTCOME MEASURES: Health care costs and use in the years before and after initial ADHD diagnosis as well as costs of ADHD-related services. RESULTS: Compared with children without ADHD, children with ADHD had mean costs that were $488 more in the second year before their ADHD diagnosis, $678 more in the year before their diagnosis, $1328 more in the year after their diagnosis, and $1040 more in the second year after their diagnosis. Asian Americans diagnosed with ADHD had lower total ADHD-related mean costs per year than white Americans diagnosed with ADHD ($221 lower), and Asian Americans, African Americans, and Hispanic Americans all had lower ADHD-related pharmacy mean costs than white Americans ($95, $63, and $77 lower, respectively). CONCLUSIONS: Children with ADHD use significantly more health services before and after their diagnosis than children without ADHD. Among children diagnosed with ADHD, nonwhite Americans (especially Asian Americans) use fewer ADHD-related services than white Americans.
